摘要：閥控蓄電池的廣泛使用對于在線監測是非常重要的課題。本文介紹了以LEM公司蓄電池傳感器Sentinel模塊為基礎的蓄電池在線監測硬件平臺的構成，并介紹了基于ARM9的蓄電池在線監測主機，現場進行了整機聯調，給出了測試結果。實驗證明該平臺可以應用于蓄電池在線監測。 敘詞：閥控蓄電池 在線監測 Sentinel 硬件平臺 ARM9 Abstract：The wide application of valve-regulated Battery makes online monitoring an important topic for study. The article introduces the components of online hardware monitoring platform based on Sentinel module, battery sensor by LEM company, and also presents battery online monitoring host computer based on ARM9. on-the-spot whole-machine combined debugging was conducted and test results were given. The experiment tells that the platform can be applied to battery online monitoring. Keyword：Valve-regulated battery, Online monitoring, Sentinel, Hardware platform, ARM9
