[0036] see figure 1 , is a flow chart of a method for controlling gear wear of an electric actuator provided in Embodiment 1 of the present invention. The gear wear control method of the electric actuator specifically includes:
[0037] Step S10, controlling the valve to move to the first mechanical stop position;
[0038] It should be noted that the operation of the control valve to the first mechanical stop position must be performed under the premise that the electric actuator stops working, otherwise the electric actuator will be affected.
[0039]Step S20, the threshold value of the number of turns of the motor controls the operation of the valve, and the stop position of the valve is the detection position;
[0040] Step S30, judging whether the detected position is the same as the standard position.
[0041] Wherein, when the detection position is different from the standard position, it is judged that the electric actuator is in the first gear wear state; when the d...

[0057] see image 3 , the embodiment of the present invention also provides a device 100 for controlling wear of the gear of an electric actuator. Wherein, the electric actuator gear wear control device 100 includes, for example: a judging module 110 for judging the relationship between the detection position and the standard position; an angle monitoring module 120 for detecting the angle of valve rotation; a control module 130 for Control the rotation of valves and motors.
[0058] Preferably, the electric actuator gear wear control device 100 further includes, for example: a display module 140 for displaying that the electric actuator 200 is in the normal state or the first gear wear state or the second gear wear state or the third gear wear state or shut down State: the alarm module 150 is used to prompt the user that the electric actuator 200 is in the third gear wear state.
[0059] In a specific embodiment, the judging module 110, the angle monitoring module 120, the ...

[0061] The embodiment of the present invention also provides an electric actuator 200, including a readable storage medium storing a computer program and a packaging IC electrically connected to the readable storage medium. When the computer program is read and run by the packaging IC, the electric actuator realizes the above-mentioned The method for controlling gear wear of an electric actuator described in any one of the embodiments.
[0062] The packaged IC in this embodiment may be, for example, a processor chip, and the processor chip is electrically connected to a computer-readable storage medium to read and execute the computer program. The packaged IC may also be a packaged circuit board, and the circuit board is packaged with a processor chip capable of reading and executing the computer program; of course, the circuit board may also package a computer-readable storage medium.
[0063] Wherein, the processor chip can also be provided with the electric actuator blockin...
