Abstract

Embodiments of the present application provide a computer device, a storage medium, and a state detection method, device, and system for a servo motor. The method includes: sampling the feedback voltage output by the servo motor according to the sampling period to obtain the sampling value, and accumulating the quantity of the sampling value to obtain the first set quantity; according to the sampling value, the first set quantity and the sampling period , generate a slope value; judge that the number of accumulated slope values ​​is less than the accumulated threshold or equal to the accumulated threshold; if it is judged that the number of slope values ​​is less than the accumulated threshold, continue to perform the step of sampling the feedback voltage output by the servo motor; When the number of out-of-slope values ​​is equal to the accumulated threshold, it is judged whether the successive accumulated thresholds and the slope values ​​are all smaller than the slope threshold, and the servo motor is controlled by the motor driver chip according to the judgment result. The embodiment of the present application improves the detection timeliness and reduces the detection cost.

Description

【Technical field】 [0001] The present application relates to the technical field of motors, and in particular, to a computer equipment, a storage medium, and a state detection method, device, and system for a servo motor. 【Background technique】 [0002] In the automotive air conditioning control system, the servo motor inside the air conditioning box is an important control component. If the servo motor has abnormal feedback voltage sampling or is stuck by foreign objects during operation, and the electronic control board fails to receive the abnormal information and still drives the servo motor to rotate, it will cause the motor to heat and damage or the stuck motor will be damaged. In the case of interruption by foreign objects, the servo motor cannot continue to rotate at this time, which is called stalled rotor. [0003] In the related art, it is possible to determine whether the servo motor is stalled by collecting the temperature of the body of the servo motor. Since i...

Problems solved by technology

If the servo motor has an abnormal feedback voltage sampling or is stuck by a foreign object during operation, but the electric control board fails to receive the abnormal information and still drives the servo motor to rotate, it will cause heat damage to the motor or cause the stuck motor to rotate. In the case of interruption by foreign objects, the servo motor cannot continue to rotate at this time. This situation is called stalled.

[0003] In related technologies, it is possible to determine whether the servo motor is locked by collecting the body temperature of the servo motor. Since it takes a certain time for the temperature to rise, the detection timeliness is poor, and the temperature sampling circuit needs to be set up to collect the temperature of the body, which will increase the detection cost.
