In the following embodiment, the same reference numerals is used to refer to the same or similar elements throughout.
The establishing module 110 obtains a processing parameter and power consumption information of a motor of the processing machine to establish a characteristic curve of the processing parameter and the power consumption information. In the embodiment, the motor includes, for example, a spindle motor and a three-axis servo motor. The processing parameter comprises a spindle motor speed and a servo feed speed.
Further, before the processing parameter and the power consumption information of the motor of the processing machine are obtained, it requires different processing parameters for the motor to observe the power consumption of the motor to obtain the relationship between the performance and the power consumption of the motor. Assuming that the spindle motor speed sets 500, 1000, 2000, 3000 RPM, respectively, a power consumption measurement is performed for the spindle motor under these spindle motor speed, so as to obtain the spindle motor speeds and the corresponding power consumption information of the spindle motor. The establishing module 110 establishes the characteristic curve of the spindle motor speed and the power consumption information according to the obtained spindle motor speed and the corresponding power consumption information.
Similarly, assuming that the servo feed speed sets 200, 500, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, 5000, 5500, 6000 mm/min, respectively, and a power consumption measurement is performed for the three-axis servo motor under these servo feed speeds, so as to obtain the servo feed speed and the corresponding power consumption information of the three-axis servo motor. The establishing module 110 establishes the characteristic curve of the servo feed speed and the power consumption information according to the obtained servo feed speed and the corresponding power consumption information. Further, the servo feed speed is, for example, expressed as V=R×Pb, wherein R is motor speed (RPM), Pb is ball screw pitch of servo shaft (mm), and V is the servo feed speed.
After establishing the characteristic curve, the establishing module 110 may establish a coupling model of the processing parameter and an electricity consumption by using a curve fitting method according to the characteristic curve. That is, the establishing module 110 establishes a coupling model of the processing parameter (i.e. the spindle motor speed and the servo feed speed) and an electricity consumption by using a curve fitting method according to the above obtained characteristic curve of the spindle motor speed and the power consumption information and the above obtained characteristic curve of the servo feed speed and the power consumption information, so as to perform the subsequent process.
The obtaining module 120 obtains a processing chipping instruction of the motor, a unit electricity and a processing time cost. In the embodiment, the processing chipping instruction of the motor is, for example, NC program code, i.e. G01, G02, G03, etc. The unit electricity is, for example, cost of the processing machine per kilowatt (NTD/degree). The processing time cost is, for example, the unit processing time cost (NTD/hr) of the processing machine multiplied by the processing time (hr).
The processing module 130 is coupled to the establishing module 110 and the obtaining module 120 and calculates a processing time, an electricity cost and a comprehensive cost of the processing machine according to the processing chipping instruction of the motor, the unit electricity, the processing time cost and the coupling model, so as to optimize the processing machine.
That is, the processing module 130 may analyze the processing chipping instruction of the motor, the unit electricity, the processing time cost and the coupling model and calculate the processing time, the electricity cost and the comprehensive cost of the processing machine according to an analysis result, so as to optimize the processing machine. Therefore, without affecting the processing accuracy, the device may effectively improve the processing efficiency and reduces the power consumption, such that the factory may achieve the effect of energy saving and carbon reduction and increase the production efficiency.
In the embodiment, the above electricity cost is, for example, the electricity consumption (KW) multiplied by the processing time (hr) and the unit electricity (NTD/hr), and the comprehensive cost is, for example, the electricity cost added with the processing time cost. The processing efficiency may convert the time cost obtained by saving the time to the processing cost, such as Mcr=Mt×Hr, wherein Mcr is the processing cost saved by increasing the processing efficiency, Mt is the saved processing time (hr), and Hr is processing time cost (NTD/hr). P=I×V and 1 kWh=1000 W*hr may be further used, so as to convert the increasing amount of the power efficiency to the electricity cost saved (=the degree of the saved electricity×electricity cost/degree), wherein P is the power of the power consumption (W), I is motor current (A), V is motor voltage (V). Then, the sum of the processing cost and the electricity cost is the comprehensive benefit of processing and energy saving. The optimization of process needs to be better than the original system, i.e. the goal of collaborative optimization design.
Further, the processing module 130 further receives an adjustment instruction, wherein the adjustment instruction is used for adjusting the processing parameter, the unit electricity, the processing time, the electricity cost and the comprehensive cost. That is, the user may adjust the processing parameter, the unit electricity, the processing time, the electricity cost and the comprehensive cost according to the requirement thereof, and the adjustment instruction of the above content is generated to the processing module 130 through a human-machine interface. Then, the processing module 130 may calculate an updating processing time, an updating electricity cost and an updating comprehensive cost according to the adjustment instruction and the coupling model, so as to optimize the processing machine. Therefore, under the adjustment of the parameter that is expected to be modified by the user, it may effectively improve the processing efficiency and reduces the effect of the power consumption, such that the factory may achieve the effect of energy saving and carbon reduction and increase the production efficiency.
According to the above description of the embodiment, it may sum up a method for synchronously optimizing efficiency and energy consumption of a processing machine.
In step S210, the method involves obtaining a processing parameter and power consumption information of a motor of the processing machine to establish a characteristic curve of the processing parameter and the power consumption information. In step S220, the method involves establishing a coupling model of the processing parameter and an electricity consumption by using a curve fitting method according to the characteristic curve. In step S230, the method involves obtaining a processing chipping instruction of the motor, a unit electricity and a processing time cost. In step S240, the method involves calculating a processing time, an electricity cost and a comprehensive cost of the processing machine according to the processing chipping instruction of the motor, the unit electricity, the processing time cost and the coupling model, so as to optimize the processing machine.
In step S310, the method involves receiving an adjustment instruction, wherein the adjustment instruction is used for adjusting the processing parameter, the unit electricity, the processing time, the electricity cost and the comprehensive cost. In step S320, the method involves calculating an updating processing time, an updating electricity cost and an updating comprehensive cost according to the adjustment instruction and the coupling model to optimize the processing machine.
As mentioned above, According to the method and the device for synchronously optimizing efficiency and energy consumption of the processing machine disclosed by the embodiments of the present disclosure, a processing parameter and power consumption information of a motor of the processing machine is obtained to establish a characteristic curve of the processing parameter and the power consumption information.

A processing time, an electricity cost and a comprehensive cost of the processing machine are calculated according to the processing chipping instruction of the motor, the unit electricity, the processing time cost and the coupling model, so as to optimize the processing machine. Therefore, in the case without affecting the processing accuracy, it may effectively improve the processing efficiency and reduces the power consumption, such that the factory may achieve the effect of energy saving and carbon reduction and increase the production efficiency.
Additionally, an adjustment instruction may be further received, wherein the adjustment instruction is used for adjusting the processing parameter, the unit electricity, the processing time, the electricity cost and the comprehensive cost, and an updating processing time, an updating electricity cost and an updating comprehensive cost are calculated according to the adjustment instruction and the coupling model, so as to optimize the processing machine.
