分布式控制电动自行车充电桩的网关系统设计

Design of Gateway System for Distributed Control of Electric Bicycle Charging Pile

本文基于RT-Thread设计了一种分布式控制电动自行车充电桩的网关系统。在这个系统中,网关负责整个系统与服务器数据的交互,还要维护与设备之间的通信,是设备与服务器交互的纽带。本文给出网关系统的硬件电路设计与任务设计,网关系统主控采用GD32F103VET6,除了主芯片自带的RTC和看门狗外,还要有局域网通信模块、4G通信模块、485通信模块、Flash存储模块。任务设计上通过成熟的通信协议来维护内网与外网的通信,通过可靠的程序设计策略,保证整个系统有非常高的稳定性。完成充电桩一系列需要采集和上传的指令。

In this paper, a gateway system for distributed control of electric bicycle charging piles is designed based on RT-Thread. In this system, the gateway is responsible for the data interaction between the entire system and the server, and it also maintains the communication with the device, which is the link between the device and the server. This article gives the hardware circuit design and task design of the gateway system. The main control of the gateway system uses GD32F103VET6. In addition to the RTC and watchdog that comes with the main chip, there are also LAN communication modules, 4G communication modules, 485 communication modules, and Flash storage module. In the task design, the communication between the internal network and the external network is maintained through a mature communication protocol, and a reliable program design strategy is adopted to ensure that the entire system has a very high stability. Complete a series of instructions that need to be collected and uploaded on the charging pile.
