Abstract
The invention discloses a digital controller of a high-speed switch valve. The controller comprises an STM32 main control chip circuit, a power supply circuit, a CAN communication circuit, a high-speed switch valve driving circuit, a modulation-demodulation circuit, a temperature and pressure sensor and a differential pressure sensor. The STM32 main control chip circuit is electrically connected with the power supply circuit, the CAN communication circuit, the high-speed switch valve driving circuit and the modulation-demodulation circuit. The high-speed switch valve driving circuit has the beneficial effects that the response speed during valve opening and closing is increased through the design of the high-speed switch valve driving circuit; due to the design of the LVDT modulation-demodulation circuit, high-precision displacement detection can be completed; due to the design of a sensor circuit, precise pressure closed-loop control and temperature compensation of a valve port flow coefficient can be achieved; the system has the advantages of complete functions, excellent performance, wide applicability and the like.
