In order to solve the problem of high power consumption in the domestic chamber pressure test system, a low power consumption chamber pressure test system based on RISC-V open source instruction set CH32V203 microcontroller is designed. In order to reduce the power consumption in standby mode, the low power chip is selected, and the multi-module power supply is used to reduce the power consumption in non-working mode, the perception of different running states of the system is realized by using the inverted switch, and the detailed design of the system running state machine is carried out. The test system has good low power consumption, and the minimum power consumption of the chamber pressure test system is 8.14 mAh, which can meet the application requirements of GB2973A-2008, it provides a reference for the Low-power electronics of domestic chamber pressure test systems, and promotes the process of domestic substitution of chamber pressure test system.
