For convenient description, a detailed description will be made below to some nouns or terms appearing in the present disclosure:

Power Line Communication (PLC): is a unique communication manner of the power system. Power Line Communication refers to the technology of transmitting analog or digital signals at high speed in a carrier manner using the existing power lines.

Electronic Magnetic Compatibility (EMC): refers to the ability of a device or system to operate by conforming to the requirements in an electromagnetic environment without producing unendurable electromagnetic interference to any device in its environment. EMC comprises requirements in two aspects: on the one hand, it means that the electromagnetic interference produced by the device in the environment during normal operation cannot exceed a certain limit; on the other hand, there is a certain degree of resistance to electromagnetic interference present in the environment, i.e. electromagnetic sensitivity.

Power line communication technology: is power system communication with a power transmission line as a transmission medium of a carrier signal. Since the power transmission line has a very solid support structure erected with more than three conductors, the transmission line uses power frequency current to transmit a carrier signal whilst conveying power frequency current.

Channel: is a physical passage to convey information.

Coupling: refers to a phenomenon that there is close coordination and mutual influence between the input and output of two or more circuit elements or electrical networks, and energy is transmitted from one side to the other by interaction.

Carrier: refers to a radio wave of a specific frequency, which is a waveform modulated to transmit a signal, and generally a sine wave.

Noise power: also e.g., an equivalent noise power, is an incident infrared radiation power required when the signal-to-noise ratio is 1, also that is, the output voltage generated by the infrared radiation power projected on the microbolometer is equal to the noise voltage of the microbolometer itself.

Embodiment 1

When the power line communication technology is applied to the air-conditioning system in the related art, the communication signal conflicts with the EMC standard requirements of electromagnetic compatibility, which further results in the EMC bottleneck problem of the power line communication technology in the disclosure of the air-conditioning system.

In order to solve the above-described problem, a power adjustment system is proposed in some embodiments of the present disclosure. FIG. 1 is a schematic view of a power adjustment system according to some embodiments of the present disclosure. As shown in FIG. 1, the power adjustment system comprises: an air-conditioning control module 11, a noise intercepting module 13, a communication module 15, and channels 17 and 19.

The air-conditioning control module 11 is configured to set the communication network's transmission power and minimum number of communication sub-carriers according to an allowed minimum value determined by the communication network. It should be noted that, the transmission power has to be less than a threshold allowed by the EMC standards; the noise intercepting module 13 is configured to intercept the noise characteristics of the air-conditioning unit in real time; the communication module 15 is configured to adjust a state of a corresponding communication sub-carrier according to the power adjustment data generated by the air-conditioning control module 11; the channels 17 and 19 are both connected to the noise intercepting module 13 and the communication module 15, for signal transmission.

In some embodiments, the air-conditioning unit after power-on starts to work, and the air-conditioning control module 11 sends an intercepting instruction to the noise intercepting module 13, so that the noise intercepting module 13 starts real-time intercepting. The intercepting instruction comprises the noise amplitude of a frequency point of the communication sub-carrier needed to be intercepted. After receiving the intercepting instruction, the noise intercepting module 13 starts to receive and analyze the noise value generated on the power line by the air-conditioning unit during the process of operation in real time, and extracts its amplitude according to the frequency point of the communication sub-carrier to form data, and returns the data to the air-conditioning control module 11.

In addition, when receiving a noise value of each communication sub-carrier written in by the noise intercepting module 13 or externally, the air-conditioning control module 11 may perform a superposition operation according to a minimum power P1 allowed by the communication network. In some embodiments, the minimum power P1 and the noise power are added to obtain a superimposed power which is then compared with the EMC threshold. In the case where the superimposed power is greater than the EMC threshold, the transmission power value of the communication sub-carrier is reduced, so that the superimposed power is within the range of the above-described EMC threshold. Since there are a plurality of communication sub-carriers described above, it is necessary to calculate a superimposed power of each of the communication sub-carriers to form the power adjustment data corresponding to each communication sub-carrier, and then send the power adjustment data to the communication module 15, which then adjusts a state of the carrier channel of each communication sub-carrier according to the above-described power adjustment data, so as to ensure that the air-conditioning system may communicate normally.

It should be noted that, in the case where the requirements of the EMC standards cannot be met in a minimum power output state, there is a need to report a communication failure, thus prompting that it is necessary to reduce the noise interference of an air-conditioning unit itself.

In addition, it should be noted that, during the entire adjustment process, the above-mentioned communication module 15 only serves as an execution unit, and all the operation instructions need to be executed according to the air-conditioning control module 11.

Embodiment 2

According to some embodiments of the present disclosure, some method embodiments of a power adjustment method are provided. It should be noted that the steps shown in the flowchart of the accompanying drawings may be executed in a computer system such as a set of computer-executable instructions. Moreover, although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a sequence different from here.

FIG. 2 is a flowchart of a power adjustment method according to some embodiments of the present disclosure. As shown in FIG. 2, the power adjustment method comprises the following steps:

In step S202, a plurality of noise values are obtained, wherein the plurality of noise values comprise: a plurality of power line communication (PLC) noise values corresponding to a plurality of communication sub-carriers, and a background noise value of an air-conditioning unit itself. Each of the plurality of noise values comprises a PLC noise value corresponding to a communication sub-carrier and the background noise value of the air-conditioning unit.

In step S204, a plurality of noise powers corresponding to a plurality of noise values are determined. Each of the plurality of noise values corresponds to a noise power.

In step S206, power adjustment data of a plurality of communication sub-carriers is generated according to a plurality of noise powers.

In order to facilitate management, it is possible to establish a mapping relationship between the above-described power adjustment data and a plurality of noise powers in one-to-one correspondence, so as to form a power adjustment data table.

In step S208, the transmission power values of a plurality of communication sub-carriers are adjusted according to the power adjustment data.

By the above-described steps, it is possible to obtain a plurality of noise values, wherein the plurality of noise values comprise a plurality of PLC noise values corresponding to a plurality of communication sub-carriers, and a background noise value of an air-conditioning unit itself, then determine a plurality of noise powers corresponding to a plurality of noise values. Next, the power adjustment data of the plurality of communication sub-carriers are generated according to a plurality of noise powers and then the transmission power values of the plurality of communication sub-carriers are adjusted according to the power adjustment data. Compared with the related art where there is a drawback of EMC bottleneck when the power line communication technology is applied to the air-conditioning system, the power adjustment method provided by some embodiments of the present disclosure may realize the purpose that in the case where the EMC requirements cannot be met when the power line communication technology is applied to the air-conditioning system, the transmission power of the communication sub-carriers meets the EMC requirements in such a manner as to dynamically adjust the output power of the communication sub-carriers, so as to achieve the effect of reducing the intensity of the communication sub-carriers so that the transmission power of the communication sub-carriers meets the EMC requirements, thereby solving the technical problem that it is impossible to apply the power line communication technology to the air-conditioning system according to the output power of the communication sub-carrier in the related art.

As some alternative embodiments, the step S202 described above of that a plurality of noise values are obtained comprises step S2021 and step S2022 (as shown in FIG. 4). In step S2021, an intercepting instruction for obtaining a plurality of noise values is received, wherein the intercepting instruction carries a plurality of amplitudes corresponding to the frequency points of a plurality of communication sub-carriers needed to be intercepted. And in step 2022, a plurality of noise values according to the intercepting instruction are obtained. A frequency point of the communication sub-carrier corresponds to an amplitude. The above-mentioned a plurality of noise values can be obtained in the following manner.

First, in the case where the power line communication operates, the air-conditioning unit is powered on and started to work, and the air-conditioning control module sends an intercepting instruction to the noise intercepting module, so that the noise intercepting module starts real-time intercepting. The intercepting instruction comprises the noise amplitudes of the frequency points of the communication sub-carriers needed to be intercepted. After receiving the intercepting instruction, the noise intercepting module starts to receive and analyze the noise value generated on power line by the air-conditioning unit during the process of operation in real time, and extracts its amplitude according to the frequency point of the communication sub-carrier to form data, and returns the data to the air-conditioning control module.

Second, in the case where the power line communication does not operate, the air-conditioning unit is powered on to a rated operation state, the noise spectrum value is read by a spectrum analysis tool (for example, spectrum analyzer, EMC receiver), and then the corresponding communication carrier noise value is written into the air-conditioning control module for storage and analysis.

As some alternative embodiments, the step S206 described above of that power adjustment data of a plurality of communication sub-carriers is generated according to a plurality of noise powers comprises step S2061, step S2062 and step S2063 (as shown in FIG. 4). In step S2061, a minimum power is determined which is allowed by the communication network where the plurality of communication sub-carriers are located. In step S2062, a plurality of superposition powers corresponding to a plurality of frequency points of a plurality of communication sub-carriers are determined according to the minimum power and a plurality of noise powers. And in step S2063, power adjustment data are generated according to the plurality of superposition powers. For example, a superposition power of each frequency point corresponding to the communication sub-carrier is determined according to the minimum power and each of the plurality of noise powers; power adjustment data is generated according to each superposition power.

In some embodiments, generating power adjustment data according to a plurality of superimposed powers comprises: determining whether the plurality of superimposed powers are greater than electromagnetic compatibility (EMC) thresholds corresponding to a plurality of frequency points, so as to obtain a determination result; generating power adjustment data according to the plurality of superimposed powers and the EMC thresholds in the case where there is a determination result that the plurality of superimposed powers are greater than electromagnetic compatibility (EMC) thresholds corresponding to a plurality of frequency points. For example, as shown in FIG. 5, in step S20631, determining whether each of the plurality of superimposed powers is greater than an electromagnetic magnetic compatibility (EMC) threshold of the frequency point corresponding to the each of the plurality of superimposed powers; and in step S20632, generating the power adjustment data according to at least one of the plurality of superimposed powers and a corresponding at least one EMC threshold in the case where at least one of the superimposed powers is greater than a corresponding electromagnetic compatibility (EMC) threshold.

For example, when the noise value of each communication sub-carrier written in by the intercepting module or externally is received, the superimposition operation may be performed according to the minimum power P1 allowed by the communication network. That is, each superimposed power is obtained by a superimposition operation of P1 and the noise power, and then the superimposed power is compared with the EMC threshold corresponding to the frequency point of the communication sub-carrier. In the case where the superimposed power is greater than the EMC threshold corresponding to the frequency point of the communication sub-carrier, the transmission power value of the communication sub-carrier is reduced, so that the superimposed power after superimposition is within a corresponding EMC threshold range. Since there are a plurality of communication sub-carriers described above, it is necessary to calculate the superimposed power of each communication sub-carrier, so as to form power adjustment data corresponding to each communication sub-carrier. Then, the power adjustment data is sent to the communication module. The communication module adjusts a state of the carrier channel of each communication sub-carrier according to the above-described power adjustment data, so as to ensure that the air-conditioning system may communicate normally.

As some alternative embodiments, the step S208 described above of that the transmission power values of a plurality of communication sub-carriers are adjusted according to the power adjustment data comprises step S2081 (as shown in FIG. 4) that power adjustment data is sent to the communication module, wherein the communication module is configured to adjust transmission power values corresponding to a plurality of communication sub-carriers according to the power adjustment data. The state of the plurality of carrier channels corresponding to the plurality of communication sub-carriers is controlled according to the power adjustment data, so as to adjust the intensity of the transmission power values corresponding to the plurality of communication sub-carriers, thereby allowing that the transmission power of the communication sub-carriers meets the EMC requirements.

In some embodiments, generating power adjustment data of a plurality of communication sub-carriers according to a plurality of noise powers comprises: determining a minimum power allowed by the communication network where the plurality of communication sub-carriers are located; determining a plurality of communication sub-carriers according to the minimum power and a plurality of noise powers; determining a plurality of superimposed powers of a plurality of frequency points corresponding to a plurality of communication sub-carriers; generating power adjustment data according to the plurality of superimposed powers.

In some embodiments, generating power adjustment data according to a plurality of superimposed powers comprises: determining whether the plurality of superimposed powers are greater than electromagnetic compatibility (EMC) thresholds corresponding to a plurality of frequency points, so as to obtain a determination result; generating power adjustment data according to the plurality of superimposed powers and the EMC thresholds in the case where there is a determination result that the plurality of superimposed powers are greater than electromagnetic compatibility (EMC) thresholds corresponding to a plurality of frequency points.

In some embodiments, adjusting transmission power values of a plurality of communication sub-carriers according to the power adjustment data comprises: sending the power adjustment data to the communication module, wherein the communication module is configured to adjust transmission power values corresponding to the plurality of communication sub-carriers according to the power adjustment data.
