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.
