It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] See also Figure 1As shown, a DC motor operation performance test and analysis system based on data analysis includes a performance test and analysis platform, and the performance test and analysis platform is communicatively connected with a no-load test unit, a load test unit, a brake test unit and an overall test performance evaluation unit;

[0033] Example 1

[0034] This embodiment performs an operating performance test on the DC motor, performs performance tests in three different operating stages: no-load, load, and braking, and performs accurate performance platform detection on the DC motor in real time based on the test data;

[0035] The performance test analysis platform generates a no-load test signal and sends the no-load test signal to the no-load test unit. After receiving the no-load test signal, the no-load test unit performs a performance test on the DC motor in the no-load state. By judging whether the no-load performance of the DC motor is qualified under the no-load state of the DC motor, it can be inferred whether the operation of the DC motor in the current state meets the requirements, thereby improving the performance test efficiency of the DC motor.

[0036] Set a no-load period of the DC motor, and obtain the floating amount of the value of the insulation current between turns of the DC motor when the DC motor is subjected to the overload rated voltage and the set time threshold during the no-load period, wherein the overload rated voltage is expressed as a set value exceeding the rated voltage value, and a value range will be set during the actual test process, such as 1.1 to 1.3 times the rated voltage; the insulation current value is expressed as the current value that the inter-turn insulation performance can withstand, and exceeding the current value indicates that the insulation is energized; at the same time, obtain the surface deformation amount of the DC motor housing when the real-time speed of the DC motor exceeds the peak speed and continues for the set time threshold during the no-load period, and compare the floating amount of the insulation current value between turns of the DC motor when the DC motor is subjected to the overload rated voltage and the set time threshold during the no-load period, and the surface deformation amount of the DC motor housing when the real-time speed of the DC motor exceeds the peak speed and continues for the set time threshold during the no-load period with the current value floating amount threshold and the surface deformation amount threshold: wherein, the time threshold set during the experiment is the time threshold set for different stages and different processes, and its specific value is set differently according to the actual experimental test process;

[0037] If the DC motor is subjected to the overload rated voltage during the no-load period and the floating amount of the internal inter-turn insulation current value of the DC motor exceeds the current value floating amount threshold when it is subjected to the set time threshold, or if the real-time speed of the DC motor during the no-load period exceeds the speed peak value and the surface deformation of the DC motor housing exceeds the surface deformation threshold when it continues for the set time threshold, then the no-load test of the DC motor is determined to be unqualified, a no-load test abnormality signal is generated and sent to the performance test analysis platform, and after receiving the no-load test abnormality signal, the performance test analysis platform performs performance debugging on the DC motor;

[0038] If the DC motor is subjected to the overload rated voltage during the no-load period and the floating amount of the internal inter-turn insulation current value of the DC motor does not exceed the current value floating amount threshold when it is subjected to the set time threshold, and the real-time speed of the DC motor during the no-load period exceeds the speed peak value and the surface deformation of the DC motor housing does not exceed the surface deformation threshold when it continues for the set time threshold, then the no-load test of the DC motor is determined to be qualified, a no-load test normal signal is generated and the no-load test normal signal is sent to the performance test analysis platform;

[0039] The performance test analysis platform generates a load test signal and sends the load test signal to the load test unit. After receiving the load test signal, the load test unit performs a performance test on the load state of the DC motor. By testing the load state of the DC motor, it is determined whether the load operation performance of the DC motor meets the actual needs, thereby ensuring the efficiency and feasibility of the use of the DC motor. The actual operation efficiency of the DC motor is improved through performance testing. At the same time, operation warnings can be issued according to the load test, thereby reducing the risk of operation failures of the DC motor.

[0040] Set the load period of the DC motor, obtain the instantaneous floating amount of the speed value when the torque is continuously increased under the action of 1.5 times the continuous rated torque of the DC motor during the load period, and obtain the maximum rising span of the temperature rise speed of any internal component when the DC motor is continuously loaded during the load period, and compare the maximum rising span of the temperature rise speed of any internal component when the DC motor is continuously loaded during the load period and the instantaneous floating amount of the speed value when the torque is continuously increased under the action of 1.5 times the continuous rated torque of the DC motor during the load period with the maximum rising span threshold of the temperature rise speed and the instantaneous floating amount threshold of the speed value respectively:

[0041] If the maximum rising span of the temperature rise speed of any internal component exceeds the maximum rising span threshold of the temperature rise speed when the DC motor is continuously loaded during the load period, or if the DC motor is subjected to 1.5 times the continuous rated rated torque during the load period, and the instantaneous floating amount of the speed value exceeds the instantaneous floating amount threshold of the speed value when the torque is continuously increased, then it is determined that the load test analysis of the DC motor during the load period is abnormal, a load test abnormality signal is generated and sent to the performance test analysis platform, and after receiving the load test abnormality signal, the performance test analysis platform replaces the internal components of the DC motor and reduces the rated power of the DC motor at the same time;

[0042] If the maximum temperature rise span of any internal component of the DC motor does not exceed the maximum temperature rise span threshold when the DC motor is continuously loaded during the load period, and the instantaneous fluctuation of the speed value does not exceed the instantaneous fluctuation threshold when the torque is continuously increased under the action of 1.5 times the continuous rated torque of the DC motor during the load period, then it is determined that the load test analysis of the DC motor during the load period is normal, a load test normal signal is generated, and the load test normal signal is sent to the performance test analysis platform;

[0043] The performance test analysis platform generates a braking test signal and sends the braking test signal to the braking test unit. After receiving the braking test signal, the braking test unit performs a braking performance test on the DC motor to determine whether the current DC motor braking performance meets the actual operation scenario of the DC motor, ensures that the braking efficiency is qualified, and ensures that the DC motor braking efficiency is qualified and the safety meets the actual operation, avoiding unnecessary wear of the DC motor;

[0044] The end time of the load period is taken as the starting point, and the stopping time of the DC motor is taken as the end point to set the braking period of the DC motor, and the maximum deviation value of the motor braking time under different speed operation scenarios of the DC motor in the braking period and the rising span value of the temperature rise peak value of the same component when the DC motor is not braked in the braking period are obtained, and the maximum deviation value of the motor braking time under different speed operation scenarios of the DC motor in the braking period and the rising span value of the temperature rise peak value of the same component when the DC motor is not braked in the braking period are compared with the maximum deviation value threshold of the time and the rising span value threshold of the temperature rise peak value respectively:

[0045] If the maximum deviation value of the motor braking time under different speed operation scenarios of the DC motor during the braking period exceeds the maximum deviation value threshold, or the rising span value of the temperature rise peak of the same component during non-same braking execution of the DC motor during the braking period exceeds the rising span value threshold of the temperature rise peak, then the braking test analysis of the DC motor is determined to be abnormal, a braking test abnormality signal is generated and the braking test abnormality signal is sent to the performance test analysis platform. After receiving the braking test abnormality signal, the performance test analysis platform replaces the specifications of the braking components of the DC motor and adjusts the braking speed during the operation of the DC motor to slow down the braking speed and reduce the impact of the temperature rise.

[0046] If the maximum deviation value of the motor braking time under different speed operation scenarios of the DC motor during the braking period does not exceed the maximum deviation value threshold of the time consumption, and the rising span value of the temperature rise peak of the same component during non-same braking execution of the DC motor during the braking period does not exceed the rising span value threshold of the temperature rise peak, then it is determined that the braking test analysis of the DC motor is normal, a braking test normal signal is generated, and the braking test normal signal is sent to the performance test analysis platform;

[0047] Example 2

[0048] The previous embodiment tests the DC motor in different states, and this embodiment compares and analyzes the conversion process of the DC motor in different states, thereby improving the comprehensiveness of the DC motor performance test;

[0049] After receiving the normal signal of the no-load test, the normal signal of the load test and the normal signal of the brake test, the performance test analysis platform generates an overall test performance evaluation signal and sends the overall test performance evaluation signal to the overall test performance evaluation unit;

[0050] After receiving the overall test performance evaluation signal, the overall test performance evaluation unit compares and analyzes the state conversion process during the DC motor test, and performs conversion analysis according to the no-load state, load state and braking state in the test process, thereby improving the accuracy of the DC motor performance test. The motor operation performance is tested more accurately through state conversion, which is beneficial to the DC motor operation efficiency detection and improves the feasibility of the DC motor operation performance.

[0051] Obtain the stable control time deviation value of the motor rated speed deviation amount corresponding to the no-load state and the load state during the DC motor performance test, and the continuous rise time of the temperature rise peak value of the same motor component under the load state and the braking state during the DC motor performance test, and mark the stable control time deviation value of the motor rated speed deviation amount corresponding to the no-load state and the load state during the DC motor performance test, and the continuous rise time of the temperature rise peak value of the same motor component under the load state and the braking state during the DC motor performance test as GPC and WSS respectively; obtain the temperature deviation value of the DC motor running start time corresponding to the no-load state in adjacent tests during the DC motor performance test, and mark the temperature deviation value of the DC motor running start time corresponding to the no-load state in adjacent tests during the DC motor performance test as WDP;

[0052] By formula The overall test performance evaluation coefficient FG during the DC motor performance test is obtained, where fae1, fae2 and fae3 are preset proportional coefficients of the stable control time deviation value, the temperature rise peak continuous rise time and the temperature deviation value, respectively, and e is a natural constant, and β is an error correction factor with a value of 1.5;

[0053] Compare the overall test performance evaluation coefficient FG during the DC motor performance test with the overall test performance evaluation coefficient threshold:

[0054] If the overall test performance evaluation coefficient FG exceeds the overall test performance evaluation coefficient threshold during the DC motor performance test, the overall evaluation of the DC motor performance test is determined to be abnormal, an overall evaluation abnormality signal is generated and the overall evaluation abnormality signal is sent to the performance test analysis platform. After receiving the overall evaluation abnormality signal, the performance test analysis platform resets the working parameters of the DC motor and performs inspections on each component, and in the subsequent DC motor performance test process, increases the number of performance tests in each state;

[0055] If the overall test performance evaluation coefficient FG does not exceed the overall test performance evaluation coefficient threshold during the DC motor performance test, the overall evaluation of the DC motor performance test is determined to be normal, an overall evaluation normal signal is generated, and the overall evaluation normal signal is sent to the performance test analysis platform;

[0056] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;

[0057] When the present invention is in use, the no-load test unit performs a performance test on the no-load state of the DC motor, and performs a performance test analysis during the no-load period, generates a no-load test abnormal signal or a no-load test normal signal through analysis, and sends it to a performance test analysis platform; the load test unit performs a performance test on the load state of the DC motor, generates a load test abnormal signal or a load test normal signal according to the load period analysis, and sends it to the performance test analysis platform; the braking test unit performs a braking performance test on the DC motor, generates a braking test abnormal signal or a braking test normal signal through braking period analysis, and sends it to the performance test analysis platform; the overall test performance evaluation unit performs a state conversion process comparison analysis during the DC motor test.
