国产化低功耗嵌入式火炮压力测试系统设计

Design of Domestically Low‑Consumption Internal Artillery Chamber Pressure Test System

针对当前国产化膛压测试系统存在的功耗较大问题,设计了基于RISC-V开源指令集CH32V203微控制器的国产化低功耗火炮压力测试系统。为了降低待机态功耗,进行了低功耗芯片选型,并通过多模块分电源使能管理的方法减少非工作态模块功耗;利用倒置开关实现系统不同运行状态的感知,同时进行了详细的系统运行状态机设计,降低系统运行态功耗。经不同工况下的模拟应用测试,测试系统具有良好的低功耗特性,所设计的国产化火炮压力测试系统最低功耗为8.14 mAh,能够满足国军标GJB2973A-2008的应用需求,为国产化膛压测试系统的低功耗设计提供了参考方案,推动了膛压测试系统的国产化替代进程。

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 consump-tion 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 sys-tem 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 ref-erence for the Low-power electronics of domestic chamber pressure test systems,and promotes the pro-cess of domestic substitution of chamber pressure test system.
