Problems solved by technology

However, the cost of intelligent control chips currently on the market is relatively high, for example, DRV103 chip, the bulk purchase price on MOUSER is more than 33 yuan, and this chip can only control one solenoid valve
In this way, the device cost for controlling each solenoid valve is more than 33 yuan, and more additional electronic components are required to cooperate, which leads to a larger circuit board area and higher cost
Moreover, only one company can provide such chips at present, and there is a risk of out of stock and production discontinuation

Abstract

The invention provides a controller of multiple electromagnetic valves. The controller is used for controlling the multiple electromagnetic valves, and comprises a microprocessor and a plurality of switch units, wherein the switch units are correspondingly connected between the microprocessor and the multiple electromagnetic valves, the microprocessor controls the multiple electromagnetic valves through the plurality of switch units, the microprocessor outputs a pulse signal with a preset frequency and a preset duty cycle to the electromagnetic valves, so that the electromagnetic valves are enabled to keep in a power-on state; and the invention further provides an electromagnetic valve device, and the electromagnetic valve device comprises the controller of the multiple electromagnetic valves and the multiple electromagnetic valves.

Description

technical field [0001] The invention relates to the field of electromagnetic valve control, in particular to a multi-channel electromagnetic valve controller, an electromagnetic valve device including the controller, and an electromagnetic valve control method. Background technique [0002] Nowadays, if most solenoid valves are turned on for a long time, they will cause serious heat generation and high power consumption, which will affect the service life of the solenoid valve. At the same time, the impedance of the solenoid valve coil will increase as the temperature of the valve body increases, and the voltage divided by the impedance of the coil will increase accordingly, resulting in a decrease in the energy actually used to generate electromagnetic field energy. One solution is that an intelligent control chip can be used. However, the cost of intelligent control chips currently on the market is relatively high, for example, DRV103 chip, the bulk purchase price on MOUS...
