The present disclosure relates to the technical field of data processing, and particularly to a temperature processing method and apparatus.
At present, as an information source for a temperature detection system of an electric vehicle, a temperature sensor is an essential component of the temperature detection system of the electric vehicle.
In the prior art, the temperature detection system of the electric vehicle usually is configured with a thermocouple temperature sensor for temperature collection. The actual process of temperature collection is easily influenced by some interference factors, such as system lines and loads or external electromagnetic radiations.
The above interference factors will lead to the deviation of temperature measurement results and reduce the accuracy of temperature collection. In order to reduce the influences of the above interference factors on temperature collection, a filter may be added to a circuit or an appropriate filtering algorithm may be added to a system to filter a returned temperature value. However, if the temperature value returned by a temperature sensor changes at a certain moment due to external influences and an error always remains unchanged, the error cannot be found and corrected by the filter or the filtering algorithm such that the temperature value is always wrong, which may lead to other failures of the electric vehicle.

For example, if the channel corresponds to one temperature sensor, the temperature sensor corresponding to the channel may be restarted to reset the channel and perform temperature collection again. If the channel corresponds to one filtering algorithm, the corresponding filtering algorithm is reset and filtering is performed again.
On the basis of the above embodiments, further, obtaining a current frame output temperature value based on the current frame temperature value of each second effective channel includes:
Specifically, the current frame temperature values of all of the respective second effective channels are all valid, and the temperature processing apparatus calculates an average value of the current frame temperature values of all of the respective second effective channels, and take the calculated average value as the current frame output temperature value.
For example, the temperature processing apparatus calculates a current frame output temperature value Tout according to a formula
where Tk represents a current frame temperature value of a k-th second effective channel, k is a positive integer less than or equal to w, and w represents the number of the second effective channels.
S201: determining each third effective channel based on the current frame temperature value of each second effective channel.
Specifically, after determining each second effective channel, the temperature processing apparatus compares the current frame temperature value of each second effective channel with the current frame temperature value of each of the remaining second effective channels, and judges whether the second effective channel is a third effective channel based on a comparison result, and the third effective channel is uniquely corresponding to one second effective channel.

Specifically, the current frame temperature values of all of the respective third effective channels are all valid, and the temperature processing apparatus may calculate an average value of the current frame temperature values of all of the respective third effective channels, and take the calculated average value as the current frame output temperature value. For example, the temperature processing apparatus calculates a current frame output temperature value Tout according to a
where Tj represents a current frame temperature value of an j-th third effective channel, j is a positive integer less than m, and m represents the number of the third effective channels.
S301: calculating an absolute value of a difference between the current frame temperature value of the second effective channel and the current frame temperature value of each of the remaining second effective channels to obtain a comparison value corresponding to the second effective channel.
Specifically, the temperature processing apparatus calculates an absolute value of a difference between the current frame temperature value of the second effective channel and the current frame temperature value of each of the remaining second effective channels, and obtain comparison values corresponding to the second effective channel. It may be understood that there may be one or more comparison values corresponding to the second effective channel. The temperature processing apparatus obtains comparison values corresponding to all second effective channel.
For example, there are totally three second effective channels: a second effective channel A with a current frame temperature value of a, a second effective channel C with a current frame temperature value of c and a second effective channel D with a current frame temperature value of d. An absolute value of a difference between a and c is calculated as Vac an absolute value of a difference between a and d is calculated as Vad, and the comparison values corresponding to the second effective channel A are Vac and Vad. An absolute value of a difference between c and a is calculated as VCa, an absolute value of a difference between c and d is calculated as Vcd, and the comparison values corresponding to the second effective channel C are Vca and Vcd. An absolute value of a difference between d and a is calculated as Vda an absolute value of a difference between d and c is calculated as Vdc, and the comparison values corresponding to the second effective channel D are Vda and Vdc.
S302: taking the second effective channel as the third effective channel, when determining that the number of comparison values less than a third threshold among the comparison values corresponding to the second effective channel is greater than a preset value.
Specifically, each of the comparison values corresponding to the second effective channel is compared with a third threshold, and the number of comparison values less than the third threshold is counted. If the number of comparison values less than the third threshold is greater than a preset value, it means that the current frame temperature value of the second effective channel is valid, and the second effective channel is taken as the third effective channel. Each third effective channel is uniquely corresponding to one second effective channel, and the current frame temperature value of the third effective channel is equal to the current frame temperature value of the corresponding second effective channel. In this embodiment, the third threshold is set according to actual needs and is not limited herein. The preset value is set according to actual needs and is not limited herein.
For example, the preset value is 1. The comparison values corresponding to the second effective channel A are Vac and Vad, both of which are compared with the third threshold respectively. If Vac and Vad are both less than the third threshold, the number of comparison values less than the third threshold for the second effective channel A is 2, which is greater than the preset value 1, and then the second effective channel A is taken as the third effective channel. The comparison values corresponding to the second effective channel D are Vda and Vdc, both of which are compared with the third threshold respectively. If Vda is less than the third threshold and Vdc is greater than the third threshold, the number of comparison values less than the third threshold for the second effective channel D is 1, which is equal to the preset value 1, then the second effective channel D will not be taken as the third effective channel.
On the basis of the above embodiments, further, the temperature processing method according to the embodiment of the present disclosure further includes:
Specifically, each of the comparison values corresponding to the second effective channel is compared with the third threshold, and the number of comparison values less than the third threshold is counted. If the number of comparison values less than the third threshold is less than or equal to the preset value, it means that the current frame temperature value corresponding to the second effective channel is invalid, and the second effective channel may be reset.
For example, if the second effective channel corresponds to one temperature sensor, the temperature sensor corresponding to the second effective channel may be restarted to reset the second effective channel and perform temperature collection again. If the second effective channel corresponds to one filtering algorithm, the corresponding filtering algorithm is reset and filtering is performed again.
S401: obtaining a temperature variance of each first effective channel based on a variance of temperature values of a latest preset number of frames of each first effective channel.
Specifically, the temperature processing apparatus records the temperature values of the latest preset number of frames of each first effective channel, and then calculates a variance of the temperature values of the latest preset number of frames of each first effective channel to obtain a temperature variance of each first effective channel. In this embodiment, the temperature values of the latest preset number of frames of the first effective channel include the current frame temperature value of the first effective channel. The preset number of is set according to actual needs and is not limited here.
For example, when determining that the channel A is the first effective channel, the temperature processing apparatus acquires the temperature values of the latest 20 frames of the first effective channel A, then calculates a variance of the temperature values of the latest 20 frames of the first effective channel A according to a variance formula, and takes the calculated variance as the temperature variance of the first effective channel A. The variance formula is expressed as follows:
Where, δ represents a temperature variance of the first effective channel, p represents an average value of temperature values of the latest n frames of the first effective channel, ti represents a temperature value of the latest i-th frame of the first effective channel, i is a positive integer less than or equal to n, and n represents a preset number.
S402: determining each second effective channel based on a second threshold and the temperature variance of each first effective channel.
Specifically, for the temperature variance of each first effective channel, the temperature processing apparatus compares the temperature variance of each first effective channel with a second threshold, and judges whether the first effective channel is the second effective channel based on a comparison result, and the second effective channel is uniquely corresponding to one first effective channel. The temperature processing apparatus obtains each second effective channel. In this embodiment, the second threshold is set according to actual needs and is not limited herein.
For example, the temperature processing apparatus compares a temperature variance of the first effective channel A with the second threshold, and if the temperature variance of the first effective channel A is less than the second threshold, it means that the temperature value obtained from the first effective channel A is stable for a time period, and the first effective channel A could be taken as the second effective channel. The temperature processing apparatus compares a temperature variance of the first effective channel C with the second threshold, and if the temperature variance of the first effective channel C is greater than or equal to the second threshold, it means that the temperature value obtained from the first effective channel C is unstable for a time period, and the first effective channel C may be reset to obtain a temperature value again.
On the basis of the above embodiments, further, determining each second effective channel based on the temperature variance of each first effective channel and a second threshold includes:
Specifically, the temperature processing apparatus compares the temperature variance of the first effective channel with the second threshold, and if the temperature variance of the first effective channel is less than the second threshold, takes the first effective channel as the second effective channel, and the second effective channel corresponds to the first effective channel. The current frame temperature value of the first effective channel is taken as a current frame temperature value of the corresponding second effective channel, and the temperature sensor or the filtering algorithm corresponding to the first effective channel is taken as a temperature sensor or a filtering algorithm corresponding to the corresponding second effective channel.
On the basis of the above embodiments, further, the temperature processing method according to the embodiment of the present disclosure further includes:
Specifically, the temperature processing apparatus compares the temperature variance of the first effective channel with the second threshold, and if the temperature variance of the first effective channel is greater than or equal to the second threshold, it means that the temperature value obtained from the first effective channel is unstable for a time period, and the first effective channel may be reset.
For example, if the first effective channel corresponds to one temperature sensor, the temperature sensor corresponding to the first effective channel may be restarted to reset the first effective channel and collect temperature again. If the first effective channel corresponds to one filtering algorithm, the corresponding filtering algorithm is reset and filtering is performed again.
S501: obtaining an effective temperature value of each first effective channel based on multi-frame temperature values of each first effective channel.
Specifically, the temperature processing apparatus acquires temperature values of a plurality of frames of each first effective channel, and obtain an effective temperature value of each first effective channel based thereon.
S502: taking the first effective channel as the second effective channel, when determining that the effective temperature value of the first effective channel is greater than a fourth threshold and less than a fifth threshold.
The temperature processing apparatus compares the effective temperature value of the first effective channel with a fourth threshold and a fifth threshold respectively, and if the effective temperature value of the first effective channel is greater than the fourth threshold and less than the fifth threshold, takes the first effective channel as the second effective channel. In this embodiment, the fourth threshold is set according to actual needs, and are not limited herein.
On the basis of the above embodiments, further, obtaining an effective temperature value of each first effective channel based on multi-frame temperature values of each first effective channel includes:
Specifically, the temperature processing apparatus calculates an absolute value of a difference between the current frame temperature value and the previous frame temperature value of the first effective channel as a neighboring difference, then compares the neighboring difference with a sixth threshold; if the neighboring difference is less than or equal to the sixth threshold, takes the current frame temperature value of the first effective channel as the effective temperature value of the first effective channel; and if the neighboring difference is greater than the sixth threshold, takes the previous frame temperature value of the first effective channel as the effective temperature value of the first effective channel. Determining the effective temperature value by the above process may effectively overcome the pulse interference caused by accidental factors. In this embodiment, the sixth threshold is set according to actual experiences and is not limited herein.
On the basis of the above embodiments, further, obtaining an effective temperature value of each first effective channel based on multi-frame temperature values of each first effective channel includes:
Specifically, the temperature processing apparatus acquires temperature values of q frames of the first effective channel, sorts the temperature values of q frames in a descending order, and obtains a temperature value in the middle of the order from the sorting results as the effective temperature value of the first effective channel, where the temperature values of q frames include the current frame temperature value of the first effective channel, and q is an odd number greater than or equal to 3. Determining the effective temperature value by the above process may effectively overcome the fluctuation and interference caused by accidental factors and achieve a good filtering effect on the slowly changed temperature.
For example, if q is 5, the temperature processing apparatus obtains temperature values of five consecutive frames including the current frame temperature value of the first effective channel, and sorts the temperature values of five frames in a descending order. The sorting results are marked as a first temperature value, a second temperature value, a third temperature value, a fourth temperature value and a fifth temperature value, in which the first temperature value is the largest and the fifth temperature value is the smallest, then the temperature value in the middle of the order, i.e., the third temperature value, is obtained as the effective temperature value of the first effective channel.
On the basis of the above embodiments, further, the current frame temperature value of each channel is obtained by a different filtering algorithm.
Specifically, each channel corresponds to a filtering algorithm, and the filtering algorithm corresponding to each channel is different from each other. The current frame temperature value of each channel is obtained by filtering by preforming different filtering algorithms to the temperature collection signal from the one same temperature sensor. In this embodiment, the filtering algorithm is selected according to actual needs and is not limited herein.
For example, three filtering algorithms, i.e., a median filtering algorithm, a nonlinear Kalman filtering algorithm and an adaptive robust Kalman filtering algorithm, are adopted to filter the temperature collection signal from the same one temperature sensor to obtain the current frame temperature values of three channels.
On the basis of the above embodiments, further, the temperature processing method provided by the embodiment of the present disclosure further includes:
Specifically, under the condition that the current frame temperature value of each channel is obtained by a different filtering algorithm, the temperature processing apparatus counts a total number of the third effective channels, and compares the total number of the third effective channels with a set value. If the total number of the third effective channels is less than the set value, it means that the temperature collection signal of the temperature sensor corresponding to each channel is invalid, and the temperature sensor corresponding to each channel may be restarted to perform temperature collection again. In this embodiment, each channel corresponds to a same one temperature sensor. The set value is set according to actual needs and is not limited herein.
On the basis of the above embodiments, further, the temperature processing method provided by the embodiment of the present disclosure further includes:
Specifically, under the condition that the current frame temperature value of each channel is obtained by a different filtering algorithm, if the temperature sensor has been continuously restarted for a first preset number of times, it means that the temperature sensor itself is failed and cannot accurately perform temperature collection, and a failure of the temperature sensor may be promoted. In this embodiment, the first preset number of times may be 3, which is set according to actual needs and is not limited herein.
For example, the failure of the temperature sensor may be prompted by an alarm message or an alarm sound.
On the basis of the above embodiments, further, the current frame temperature value of each channel is obtained by a different temperature sensor.
Specifically, each channel corresponds to a temperature sensor, the temperature sensor corresponding to each channel is different from each other, and the temperature collection object of the temperature sensor corresponding to each channel is the same. In this embodiment, each channel is configured with the same filtering algorithm to filter the temperature collection signal of the corresponding temperature sensor to obtain the current frame temperature value of the channel.
For example, five temperature sensors may be provided to collect the temperature of a same object.
On the basis of the above embodiments, further, the temperature processing method according to the embodiment of the present disclosure further includes:
Specifically, under the condition that the current frame temperature value of each channel is obtained by a different temperature sensor, the temperature processing apparatus counts the number of times of continuous restart of the temperature sensor corresponding to each channel. If the temperature sensor corresponding to the channel is continuously restarted for a second preset number of times, it means that the temperature sensor corresponding to the channel is failed and cannot accurately perform temperature collection, and a failure of the temperature sensor corresponding to the channel may be promoted. In this embodiment, the second preset number of times may be 3, which is set according to actual needs and is not limited herein.
Next, a process of performing temperature collection for a same object using three different temperature sensors is taken as an example to illustrate an implementation process of the temperature processing method according to the embodiment of the present disclosure.
A temperature detection system is provided with a temperature sensor 1, a temperature sensor 2 and a temperature sensor 3, each collecting a temperature value every 100 ms and sending it to the temperature processing apparatus, in which channel 1 is corresponding to the temperature sensor 1, channel 2 is corresponding to the temperature sensor 2, and channel 3 is corresponding to the temperature sensor 3; and the first threshold is set to 1, the second threshold is set to 1, and the third threshold is set to 1.
The temperature data obtained by the temperature sensor 1, the temperature sensor 2 and the temperature sensor 3 and related processing results are shown in Table 1.
Step 1: acquiring a current frame temperature value of each channel. Temperature data collected by a temperature sensor 1, a temperature sensor 2 and a temperature sensor 3 is sent to a temperature processing apparatus. The temperature processing apparatus obtains the current frame temperature values of channel 1, channel 2 and channel 3.
The temperature processing apparatus sequentially obtains temperature data of five frames. A first frame data includes: the current frame temperature value of channel 1 is 18.52, the current frame temperature value of channel 2 is 18.55, and the current frame temperature value of channel 3 is 18.97; a second frame data includes: the current frame temperature of channel 1 is 19.28, the current frame temperature of channel 2 is 19.19, and the current frame temperature of channel 3 is 19.24; and a third frame data, a fourth frame data and a fifth frame data is shown in Table 1 and will not be repeated here.
Step 2: calculating a current frame temperature variation of each channel. The temperature processing apparatus calculates an absolute value of a difference between the current frame temperature value and a previous frame temperature value of each of three channels, and obtain the current frame temperature variation of each of the three channels.
For the first frame data, the temperature processing apparatus calculates the absolute values of the difference between the current frame temperature value and the previous frame temperature value of each of the three channels, and obtains that a temperature variation of channel 1 is 0.24, a temperature variation of channel 2 is 0.49, and a temperature variation of channel 3 is 0.16. For the second frame data, the third frame data, the fourth frame data and the fifth frame data, the calculated temperature variations of the three channels are shown in Table 1, and will not be repeated here. In this embodiment, for the fourth frame data, since the third frame data of the temperature value of channel 3 is invalid, the temperature variation of channel 3 is calculated by subtracting the temperature value of channel 3 of the second frame data from the temperature value of channel 3 of the fourth frame data.
Step 3: judging whether each channel is a first effective channel. The temperature processing apparatus compares the current frame temperature variation of each channel with a first threshold 1; if the temperature variation of the channel is less than 1, determines that the channel is the first effective channel, and enters Step 5; and if the temperature variation of the channel is greater than or equal to 1, determines that the channel is not the first effective channel, and enters Step 4.
For the first frame data, the temperature variation of channel 1 is 0.42, the temperature variation of channel 2 is 0.49, and the temperature variation of channel 3 is 0.16, all of which are less than 1. Therefore, channel 1, channel 2 and channel 3 are all taken as the first effective channels, which may be marked as a first effective channel 1, a first effective channel 2 and a first effective channel 3, respectively. Similarly, it may be determined that channel 1, channel 2 and channel 3 are the first effective channels for the second frame data, the fourth frame data and the fifth frame data.
For the third frame data, the temperature variation of channel 1 is 0.08 and the temperature variation of channel 2 is 0.24, both of which are less than 1. Therefore, channel 1 and channel 2 are taken as the first effective channels. However, the temperature variation of channel 3 is 20.19, which is greater than 1, so channel 3 is not the first effective channel.
Step 4: restarting a temperature sensor corresponding to the channel. The temperature processing apparatus resets the channel with the current frame temperature variation greater than or equal to 1.
For the third frame data, the temperature change of channel 3 is 20.19, which is greater than 1, and channel 3 will be reset, that is, the temperature sensor 3 corresponding to channel 3 will be restarted.
For the first frame data, the second frame data, the fourth frame data and the fifth frame data, it is unnecessary to reset the channel.
Step 5: calculating a temperature variance of each first effective channel. The temperature processing apparatus obtains the temperature variance of each first effective channel based on a variance of the temperature values of the latest 20 frames of each first effective channel.
For the first frame data, the temperature processing apparatus calculates the variance of the temperature values of the latest 20 frames of each of three first effective channels, and obtains that a temperature variance of the first effective channel 1 is 0.24, a temperature variance of the first effective channel 2 is 0.23, and a temperature variance of the first channel 3 is 0.26. The temperature variances of the three channels calculated for the second frame data, the fourth frame data and the fifth frame data are shown in Table 1, and will not be repeated here.
For the third frame data, the temperature processing apparatus calculates the variance of the temperature values of the latest 20 frames of either of two first effective channels, and obtains that a temperature variance of the first effective channel 1 is 0.23 and a temperature variance of the first effective channel 2 is 0.26.
Step 6: judging whether each first effective channel is a second effective channel. The temperature processing apparatus compares the temperature variance of each first effective channel with a second threshold 1; if the temperature variance of the first effective channel is less than 1, determines that the channel is the second effective channel, and enters Step 8; and if the temperature variance of the channel is greater than or equal to 1, determines that the channel is not the second effective channel, and enters Step 7.
For the first frame data, the temperature variance of the first effective channel 1 is 0.24, the temperature variance of the first effective channel 2 is 0.23, and the temperature variance of the first effective channel 3 is 0.26, all of which are less than 1. Therefore, the first effective channel 1, the first effective channel 2 and the first effective channel 3 are all taken as the second effective channels, which may be marked as a second effective channel 1, a second effective channel 2 and a second effective channel 3, respectively. Similarly, it may be determined that the first effective channel 1, the first effective channel 2 and the first effective channel 3 are all the second effective channels for the second frame data, the fourth frame data and the fifth frame data.
For the third frame data, the temperature variance of the first effective channel 1 is 0.23 and the temperature variance of the first effective channel 2 is 0.26, both of which are less than 1. Therefore, the first effective channel 1 and the first effective channel 2 are both taken as the second effective channels.
Step 7: restarting a temperature sensor corresponding to the first effective channel. The temperature processing apparatus resets the first effective channel, that is, restarts the temperature sensor corresponding to the first effective channel, so as to perform temperature collection again.
Step 8: calculating comparison values corresponding to each second effective channel. The temperature processing apparatus calculates an absolute value of a difference between the current frame temperature value of each second effective channel and the current frame temperature value of each of the remaining second effective channels to obtain comparison values corresponding to the second effective channel.
For the first frame data, an absolute value of a difference between the current frame temperature value 18.52 of the second effective channel 1 and the current frame temperature value 18.55 of the second effective channel 2 is calculated as 0.03, an absolute value of a difference between the current frame temperature value 18.52 of the second effective channel 1 and the current frame temperature value 18.97 of the second effective channel 3 is calculated as 0.45, and then 0.03 and 0.45 are the comparison values corresponding to the second effective channel 1. Similarly, the comparison values 0.03 and 0.42 corresponding to the second effective channel 2 and the comparison values 0.04 and 0.05 corresponding to the second effective channel 3 may be calculated.
Similarly, for the second frame data, the fourth frame data and the fifth frame data, it is possible to calculate the comparison values corresponding to the second effective channel 1, the comparison values corresponding to the second effective channel 2 and the comparison values corresponding to the second effective channel 3, respectively.
For the third frame data, it is also possible to calculate the comparison values corresponding to the second effective channel 1 and the comparison value corresponding to the second effective channel 2.
Step 9: judging whether each second effective channel is a third effective channel. The temperature processing apparatus counts the number of comparison values less than a third threshold among the comparison values corresponding to the second effective channel; if the number of comparison values less than the third threshold among the comparison values corresponding to the second effective channel is greater than a preset value 0, takes the second effective channel as the third effective channel, and enters Step 11; and if the number of comparison values greater than or equal to the third threshold among the comparison values corresponding to the second effective channel is equal to 0, enters Step 10.
For the first frame data, the comparison values 0.03 and 0.45 corresponding to the second effective channel 1 are both less than 1, and the number of comparison values less than 1 is 2, which is greater than 0. The second effective channel is taken as the third effective channel and marked as a third effective channel 1. Similarly, it may be determined that the second effective channel 2 and the second effective channel 3 are both the third effective channels, which are marked as a third effective channel 2 and a third effective channel 3, respectively.
Similarly, it may be judged that the second effective channel 1, the second effective channel 2 and the second effective channel 3 are all the third effective channels for the second frame data, the fourth frame data and the fifth frame data.
Similarly, it may be judged that the second effective channel 1 and the second effective channel 2 are both the third effective channels for the third frame data.
Step 10: restarting a temperature sensor corresponding to the second effective channel. The temperature processing apparatus resets the second effective channel, that is, restarts the temperature sensor corresponding to the second effective channel, so as to perform temperature collection again.
Step 11: obtaining a current frame output temperature value. The temperature processing apparatus calculates an average value of the current frame temperature values of all of the respective third effective channel as a current frame output temperature value. Next, the flow returns to Step 1 for circulation.
For the first frame data, an average value of the current frame temperature value 18.52 of the third effective channel 1, the current frame temperature value 18.55 of the third effective channel 2 and the current frame temperature value 18.97 of the third effective channel 3 is calculated to be 18.68, so the current frame output temperature value is 18.68.
Similarly, for the second frame data, the fourth frame data and the fifth frame data, an average value of the current frame temperature values of the third effective channel 1, the current frame temperature values of the third effective channel 2 and the current frame temperature values of the third effective channel 3 are respectively calculated as the current frame output temperature values, and the calculation results are shown in Table 1.
For the third frame data, an average of the current frame temperature value 19.2 of the third effective channel 1 and the current frame temperature value 19.43 of the third effective channel 2 is calculated to be 19.32, so the current frame output temperature value is 19.32.
Next, a process of processing a temperature collection signal collected by the same one temperature sensor using three different filtering algorithms is taken as an example to illustrate an implementation process of the temperature processing method according to the embodiment of the present disclosure.
A temperature detection system is provided with a temperature sensor X which collects a temperature value every 100 ms to obtain a temperature collection signal and send it to the temperature processing apparatus. The temperature processing apparatus filters the temperature collection signal using three different filtering algorithms to obtain the current frame temperature values of three channels. In this embodiment, the three filtering algorithms are a median filtering algorithm, a nonlinear Kalman filtering algorithm and an adaptive robust Kalman filtering algorithm. The median filtering algorithm is corresponding to channel I, the nonlinear Kalman filtering algorithm is corresponding to channel II, and the adaptive robust Kalman filtering algorithm is corresponding to channel III. The first threshold is set to 1, the second threshold is set to 1, and the third threshold is set to 1.
Temperature values obtained by filtering temperature collection information of the temperature sensor X and the related processing results are shown in Table 2.
Step 1: acquiring a current frame temperature value of each channel. A temperature sensor X sends a collected temperature collection signal to a temperature processing apparatus, the temperature processing apparatus filters the temperature collection signal using three filtering algorithms to obtain current frame temperature values of channel I, channel II and channel III, respectively.
The temperature processing apparatus sequentially obtains temperature data of five frames. A first frame data includes: the current frame temperature value of channel I is 25.84, the current frame temperature value of channel II is 25.81, and the current frame temperature value of channel III is 25.88. A second frame data, a third frame data, a fourth frame data and a fifth frame data is shown in Table 2 and will not be repeated here.
Step 2: calculating a current frame temperature variation of each channel. The temperature processing apparatus calculates an absolute value of a difference between the current frame temperature value and a previous frame temperature value of each of three channels, and obtain the current frame temperature variation of each of the three channels.
For the first frame data, the temperature processing apparatus calculates the absolute values of the difference between the current frame temperature value and the previous frame temperature value of each of the three channels, and obtains that a temperature variation of channel I is 0.06, a temperature variation of channel II is 0.12, and a temperature variation of channel III is 0.07. For the second frame data, the third frame data, the fourth frame data and the fifth frame data, the calculated temperature variations of the three channels are shown in Table 2, and will not be repeated here. In this embodiment, for the fourth frame data, since the temperature value of channel II in the third frame data is invalid, the temperature variation of channel II is calculated by subtracting the temperature value of channel II of the second frame data from the temperature value of channel II of the fourth frame data.
Step 3: judging whether each channel is a first effective channel. The temperature processing apparatus compares the current frame temperature variation of each channel with a first threshold 1; if the temperature variation of the channel is less than 1, determines that the channel is the first effective channel, and enters Step 5; and if the temperature variation of the channel is greater than or equal to 1, determines that the channel is not the first effective channel, and enters Step 4.
For the first frame data, the temperature variation of channel I is 0.06, the temperature variation of channel II is 0.12, and the temperature variation of channel III is 0.07, all of which are less than 1. Therefore, channel I, channel II and channel III are all taken as the first effective channels, which may be marked as a first effective channel I, a first effective channel II and a first effective channel III, respectively. Similarly, it may be determined that channel I, channel II and channel III are the first effective channels for the second frame data, the fourth frame data and the fifth frame data.
For the third frame data, the temperature variation of channel I is 0.02 and the temperature variation of channel II is 0.03, both of which are less than 1. Therefore, channel I and channel III are taken as the first effective channels. However, the temperature variation of channel II is 23.86, which is greater than 1, so channel II is not the first effective channel.
Step 4: resetting a filtering algorithm corresponding to the channel. The temperature processing apparatus resets the channel with the current frame temperature variation greater than or equal to 1, i.e., resets the filtering algorithm corresponding to the channel.
For the third frame data, the temperature variation of channel II is 23.86, which is greater than 1, and channel II will be reset, that is, the filtering algorithm corresponding to channel II will be restarted.
For the first frame data, the second frame data, the fourth frame data and the fifth frame data, it is unnecessary to reset the channel.
Step 5: calculating a temperature variance of each first effective channel. The temperature processing apparatus obtains the temperature variance of each first effective channel based on a variance of the temperature values of the latest 20 frames of each first effective channel.
For the first frame data, the temperature processing apparatus calculates the variance of the temperature values of the latest 20 frames of each of three first effective channels, and obtains that a temperature variance of the first effective channel I is 0.62, a temperature variance of the first effective channel II is 0.43, and a temperature variance of the first channel III is 0.23. The temperature variances of the three channels calculated for the second frame data, the fourth frame data and the fifth frame data are shown in Table 2, and will not be repeated here.
For the third frame data, the temperature processing apparatus calculates the variance of the temperature values of the latest 20 frames of either of two first effective channels, and obtains that a temperature variance of the first effective channel I is 0.48 and a temperature variance of the first effective channel III is 0.35.
Step 6: judging whether each first effective channel is a second effective channel. The temperature processing apparatus compares the temperature variance of each first effective channel with a second threshold 1; if the temperature variance of the first effective channel is less than 1, determines that the channel is the second effective channel, and enters Step 8; and if the temperature variance of the channel is greater than or equal to 1, determines that the channel is not the second effective channel, and enters Step 7.
For the first frame data, the temperature variance of the first effective channel I is 0.48, the temperature variance of the first effective channel II is 0.43, and the temperature variance of the first effective channel III is 0.23, all of which are less than 1. Therefore, the first effective channel I, the first effective channel II and the first effective channel III are all taken as the second effective channels, which may be marked as a second effective channel I, a second effective channel II and a second effective channel III, respectively. Similarly, it may be determined that the first effective channel I, the first effective channel II and the first effective channel III are all the second effective channels for the second frame data, the fourth frame data and the fifth frame data.
For the third frame data, the temperature variance of the first effective channel I is 0.48 and the temperature variance of the first effective channel III is 0.35, both of which are less than 1. Therefore, the first effective channel I and the first effective channel III are both taken as the second effective channels.
Step 7: resetting the filtering algorithm corresponding to the first effective channel. The temperature processing apparatus resets the first effective channel, that is, restarts the filtering algorithm corresponding to the first effective channel, so as to perform filtering again.
Step 8: calculating comparison values corresponding to each second effective channel. The temperature processing apparatus calculates an absolute value of a difference between the current frame temperature value of each second effective channel and the current frame temperature value of each of the remaining second effective channels to obtain comparison values corresponding to the second effective channel.
For the first frame data, an absolute value of a difference between the current frame temperature value 25.84 of the second effective channel I and the current frame temperature value 25.81 of the second effective channel II is calculated as 0.03, an absolute value of a difference between the current frame temperature value 25.84 of the second effective channel I and the current frame temperature value 25.88 of the second effective channel II is calculated as 0.04, and then 0.03 and 0.04 are the comparison values corresponding to the second effective channel I. Similarly, the comparison values 0.03 and 0.07 corresponding to the second effective channel II and the comparison values 0.04 and 0.07 corresponding to the second effective channel III may be calculated.
Similarly, for the second frame data, the fourth frame data and the fifth frame data, it is possible to calculate the comparison values corresponding to the second effective channel I, the comparison values corresponding to the second effective channel II and the comparison values corresponding to the second effective channel III, respectively.
For the third frame data, it is also possible to calculate the comparison values corresponding to the second effective channel I and the comparison value corresponding to the second effective channel III.
Step 9: judging whether each second effective channel is a third effective channel. The temperature processing apparatus counts the number of comparison values less than a third threshold among the comparison values corresponding to the second effective channel; if the number of comparison values less than the third threshold among the comparison values corresponding to the second effective channel is greater than a preset value 0, takes the second effective channel as the third effective channel, and enters Step 11; and if the number of comparison values greater than or equal to the third threshold among the comparison values corresponding to the second effective channel is equal to 0, enters Step 10.
For the first frame data, the comparison values 0.03 and 0.04 corresponding to the second effective channel I are both less than 1, and the number of comparison values less than 1 is 2, which is greater than 0. The second effective channel is taken as the third effective channel and marked as a third effective channel I. Similarly, it may be determined that the second effective channel II and the second effective channel III are both the third effective channels, which are marked as a third effective channel II and a third effective channel III, respectively.
Similarly, it may be determined that the second effective channel I, the second effective channel II and the second effective channel III are all the third effective channels for the second frame data, the fourth frame data and the fifth frame data.
Similarly, it may be determined that the second effective channel I and the second effective channel III are both the third effective channels for the third frame data.
Step 10: resetting the filtering algorithm corresponding to the second effective channel. The temperature processing apparatus resets the second effective channel, that is, restarts the filtering algorithm corresponding to the second effective channel, so as to perform filtering again.
Step 11: obtaining a current frame output temperature value. The temperature processing apparatus calculates an average value of the current frame temperature values of all of the respective third effective channel as a current frame output temperature value. Next, the flow returns to Step 1 for circulation.
For the first frame data, an average value of the current frame temperature value 25.84 of the third effective channel I, the current frame temperature value 25.81 of the third effective channel II and the current frame temperature value 25.88 of the third effective channel III is calculated to be 25.84, so the current frame output temperature value is 25.84.
Similarly, for the second frame data, the fourth frame data and the fifth frame data, an average value of the current frame temperature values of the third effective channel I, the current frame temperature values of the third effective channel II and the current frame temperature values of the third effective channel III are respectively calculated as the current frame output temperature values, and the calculation results are shown in Table 2.
For the third frame data, an average of the current frame temperature value 25.79 of the third effective channel I and the current frame temperature value 25.8 of the third effective channel III is calculated to be 25.80, so the current frame output temperature value is 25.80.
In the temperature processing method according to the embodiment of the present disclosure, by the design of redundancy function for collecting temperature, whether the temperature values returned by a plurality of temperature sensors or processed by a plurality of filtering algorithms are valid or not are judged, and the accuracy of temperature collection is improved. If the temperature values are invalid, collection or processing is performed again by restarting the temperature sensors or automatically resetting the filtering algorithms to obtain valid temperature values.
Specifically, the acquisition module 801 acquires a current frame temperature value of each channel. If each channel corresponds to one temperature sensor, the temperature sensor corresponding to each channel may collect temperature in real time and send the obtained temperature value to the acquisition module 801, the acquisition module 801 takes the received temperature value collected by the temperature sensor in real time as a current frame temperature value of the corresponding channel. If each channel corresponds to one filtering algorithm and different filtering algorithms correspond to a same one temperature sensor, the temperature sensor may collect temperature in real time to obtain a temperature collection signal, and the acquisition module 801 processes the temperature collection signal using different filtering algorithms to obtain a current frame temperature value of each channel. In this embodiment, the number of the channels is at least two, which is set according to actual needs and is not limited herein.

The judgement subunit 80512 compares each of the comparison values corresponding to the second effective channel with a third threshold, and counts the number of comparison values less than the third threshold. If the number of comparison values less than the third threshold is greater than a preset value, it means that the current frame temperature value of the second effective channel is valid, and the second effective channel is taken as the third effective channel.
