摘　　要：针对现有膛压测试仪体积较大,不能满足中小口径火炮膛压测试需求的问题,本文采用存储测试技术、低功耗技术和微型化技术设计了体积为22cm3的电子测压器。该仪器充分利用单片机的片内资源,解决了系统微型化的关键问题,采用先进的电源管理技术实现了系统低功耗。它能够在发射现场实时记录膛压曲线,具有体积小、能承受600MPa高压、功耗低、无引线等优点。靶场实测结果表明设计的微型电子测压器的可靠性和测试精度满足膛压测试要求,准确可靠的测试数据能为兵器的研制和验收提供依据。Aimed at the existing problems in chamber pressure measurement such as the volume of the pressure gauge is too big to satisfy the chamber pressure testing requirements of small and medium caliber artillery. The electronic pressure gauge is designed, which adopted low power technology and miniaturization technology, which volume is 22cm3. The gauge realized system miniaturization with sufficient internal peripherals and realized low power consumption by smart power management. The gauge can record chamber pressure curve in real-time. It has the advantages of small volume, can bear high pressure up to 600MPa, low power consumption and no lead. The measured results obtained in firing range shows that the reliability and test precision of the miniature electronic pressure gauge satisfy the test requirements. Accurate and reliable test data provides the important basis for assessing artillery, gunpowder device and ballistic performance.
