Design of battery monitoring system based on near field communication and low frequency wakeup

文中提出一种近场通信与低频唤醒相结合的无线通信架构,介绍了一种用于起动电池或其他零散分布电池的无线监测系统设计。该系统由小型可植入监测板、手持机以及上位机软件组成,管理人员可使用手持机以近场刷卡方式或低频广播方式巡检起动电池。其中监测板由微控制器、蓄电池参数采集电路和无线通信电路组成,体积小、功耗低,可封装到蓄电池外壳内,实时计算蓄电池状态信息。经实验测试,该系统具备低功耗和灵活性等特性,满足监测起动电池的要求。

This paper proposes a wireless communication architecture combining near-field communication and low-frequency wakeup,and introduces the design of a wireless monitoring system for starting batteries or other scattered distributed batteries.This system is composed of a small implantable monitoring board,a handheld computer and host computer software.The administrator can use the handheld computer to patrol and start the battery by near-field card swiping or low-frequency broadcasting.The monitoring board is composed of a microcontroller,a battery parameter acquisition circuit and a wireless communication circuit.It has advantages of small size and low power consumption,and can be packaged in the battery casing to calculate the battery status information in real time.The experimental testing results show that the system has low power consumption and flexibility to meet the requirements of monitoring starting batteries.
