一种AGV调度用组合式无线通信模块的设计

Design of a Combined Wireless Communication Module for AGV Dispatching

针对目前AGV调度缺乏专用通信解决方案的情况,设计了一种"核心板+底板"的组合式无线通信模块,并制定了相应的通信协议。核心板以STM32F030C8作为控制器,通过ESP8266以串口无线透传方式与调度计算机通信;底板分为串口通信底板与开关量输入底板两种,主要用于将模块分别连接到AGV控制器与设备控制器。经实践证实,该模块掉线率基本在0.5%以内,通信稳定,同时具备安装方便、二次开发简单等优点,能适用于大部分基于WIFI通信的AGV应用项目。

Aimed at the situation that there isn’t proprietary communication solution for AGV dispatching,a combined wireless communication module of“core board+bottom board”is designed,and the corresponding communication protocol is issued.STM32F030C8 is used as the controller of the core board,and it communicates with dispatch computer by ESP8266 in the way of pass-through between serial port and WIFI.There are two kinds of bottom boards,which contain serial port communication bottom boards and ON-OFF value input bottom boards,and the bottom board is used to connect the module to the AGV controller or the equipment controller mainly.Facts prove that the module communicates stably and the dropped-call rate is under 0.5%basically,and the module also has the advantages of convenient installation,easy secondary development,etc.The module can be applied to most AGV applications based on WIFI communication.
