Instrument valve control motor control method and motor status control machine
A technology of state control and control method, which is applied to the control of instrument valve-controlled motors and the field of motor state control machines. It can solve the problems that the valve state cannot be detected in real time, and the valve cannot be opened and closed normally, so as to achieve the effect of precise valve control function.

Embodiment 1
[0071] like figure 1 As shown, the present invention provides a method for controlling a meter valve-controlled motor. In this embodiment, the meter is a photoelectric direct-reading remote water meter. The method includes the following steps:
[0072] 101. Receive an external action command, and control the state transition of the motor according to the external action command, for example, receive an external action command, and control the motor from the "idle" state to the "standby" state;
[0073] 102. Continuously detect the status of the water meter communication serial port, and output a serial port status detection signal, for example, in the motor "standby" state, continuously detect the status of the water meter communication serial port, and output a serial port status detection signal;
[0074] 103. Receive the serial port state detection signal, and control the motor to maintain or switch the state according to the serial port state detection signal. For example,...
Embodiment 2
[0078] like figure 2 As shown, on the basis of embodiment 1, in further embodiment 2, the control method of the instrument valve-controlled motor of the present invention also includes, in "receiving the valve in-position state monitoring signal, and controlling the motor to maintain or After the step of "changing the state", it may also include, 106, controlling the motor to maintain its converted state according to the set time signal, and then further controlling the motor to change the state. Specifically, when the valve in-position state monitoring signal indicates that the valve is in place, after the control motor changes from the "acting" state to the "end" state, in the "end" state of the motor, the control motor continues to operate until the motor maintains " After 200ms-300ms, it will turn to "idle" state. Preferably, in the "end" state of the motor, the motor is controlled to keep moving until the motor remains in the "end" state for 230ms-270ms, more preferably...
Embodiment 3
[0080] like image 3 As shown, on the basis of embodiment 2, in further embodiment 3, the control method of the instrument valve control motor of the present invention also includes, 201 continuously monitors the valve action time, and outputs the valve action time signal, and 202 receives the valve action Time signal, and control the motor to maintain or switch state according to the valve action time signal; at the same time, 301 continuously monitors the motor current signal and outputs the motor current signal, 302 receives the motor current signal, and controls the motor to maintain or switch state according to the motor current signal. Specifically, when the motor is in the "action" or "end" state, the valve action time is continuously monitored, and the valve action time signal is output, and the valve action time signal is received, and the motor is controlled to maintain or switch the state according to the valve action time signal. If the valve action time does not e...
