摘要
随着物联网时代的到来,实现对快速充电机的智能远程管理,其监控终端的设计是其中的关键技术。结合单片机STM32和实时操作系统μC/OS-Ⅱ,介绍了快速充电机监控终端的整体设计方案,研究了大功率充电机CAN总线及GPRS数据发送的协议制定及软件设计方法,并对GPRS流量费用进行了经济性分析。结果表明该监控终端保证监控网络工作稳定,实现对充电机的运行状态的监测及其远程管理。
With the coming of Internet of Things age, the design of monitoring terminal for fast charger becomes a key tech- nology for realizing intelligent remote management. The whole design scheme of fast charger monitoring terminal is introduced, which is in combination with the microcontroller STM32 and the real-time operating system μC/OS-Ⅱ. The protocol establish- ment and software design method for high-power charger CAN bus and GPRS data transmission are studied. The economic analy- sis of GPRS flow cost is performed. The results show that the communication network is stable, and the monitoring terminal can realize the state monitoring and remote management for the charger.
