Title:
SOLENOID VALVE CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/047442
Kind Code:
A1
Abstract:
Disclosed is a solenoid valve control apparatus. The solenoid valve control apparatus (100) is used for controlling a solenoid valve (200) on a cooling liquid radiating pipe in a device, and comprises a signal conversion chip (110) and a power supply circuit (120); the signal conversion chip (110) is connected to the power supply circuit (120), and the power supply circuit (120) is used for supplying power to the solenoid valve (200); the signal conversion chip (110) receives a liquid leakage analog signal, converts the liquid leakage analog signal into a liquid leakage digital signal, and sends the liquid leakage digital signal to a system management module (300), and the liquid leakage analog signal is used for indicating liquid leakage of the cooling liquid radiating pipe in the device; and after a control signal is received from the system management module (300), the power supply state of the power supply circuit (120) to the solenoid valve (200) is controlled according to the control signal. The signal conversion chip (110) can perform digital-to-analog conversion, once the liquid leakage analog signal reaches a conversion threshold, the signal conversion chip (110) converts the liquid leakage analog signal to the liquid leakage digital signal, the control signal is received, and the power supply circuit (120) can be accurately controlled to power on or power off the solenoid valve (200).
