In order to improve the control performance of the solenoid valve, a controller for solenoid valve group based on STC-MCU was proposed. The DC solenoid driver circuit was designed based on H-bridge integrated circuit and PWM control. A linear current sensor was used to realize current control and working status monitoring. The high-speed transmission with the upper computer for data acquisition and control command were completed by Ethernet communication. The testing results show that the solenoid valve group works stably and the repetition rate of excitation pulse type current control is high. It can be seen that the controller, with high control precision, is stable and reliable
