Problems solved by technology

Since the solenoid valve needs a large current when it is pulled in, the stability of the pull-in can be ensured by using a small current during the pull-in process. The current required to maintain stability, that is, the power dissipation is large

Embodiment Construction

[0027] A control method of a low-power solenoid valve with position state monitoring of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0028] Such as figure 1 with figure 2 As shown, a control method of a low-power solenoid valve with position status monitoring, comprising steps:

[0029] S1. The processor in the solenoid valve obtains the coil current in the solenoid valve in real time;

[0030] S2, providing a current threshold, when the coil current is greater than the current threshold, it is determined that the electromagnet in the solenoid valve acts, that is, the electromagnet generates a pull-in action;

[0031] S3. Provide a preset time and a stable current value. After the coil current is greater than the current threshold for a preset time, the processor controls the coil current to decrease to the stable current value.

[0032] Specifically, in the control method of the above-mentioned low-po...

Abstract

The invention provides a method for controlling a low-power electromagnetic valve with a position state monitoring function. The method is characterized by comprising the following steps: S1, acquiring a coil current in an electromagnetic valve in real time by a processor in the electromagnetic valve; S2, providing a current threshold value, judging that a pull-in action is generated in an electromagnet in the electromagnetic valve when the coil current is larger than the current threshold value; and S3, providing a preset time and a stable current value, and controlling the coil current to decrease to the stable current value by the processor after the coil current is larger than the current threshold value and lasting for the preset time. According to the method for controlling the low-power electromagnetic valve with the position state monitoring function, the coil current is reduced to the stable current value when the electromagnet is pulled in and the coil current is stable, so that the power consumption is reduced while the electromagnet is pulled in.

Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to a control method of a low-power solenoid valve with position state monitoring. Background technique [0002] With the continuous innovation of modern science and technology and the continuous expansion of production technology, the production process mainly embodies unmanned and fully automatic production, which effectively improves productivity and accelerates the pace of social development. The application of solenoid valves is becoming more and more extensive in our production. Solenoid valves are indispensable actuators in automatic control systems. Since the solenoid valve requires a large current when it is pulled in, the stability of the pull-in can be ensured by using a small current during the pull-in process. However, in practical applications, the current of the solenoid valve is often larger than that The current required to maintain stability, that is, the power consu...
