摘要
针对传统冷藏集装箱环境控制系统的各种参数与环节由单一控制器集中控制,系统结构复杂、非模块化、安装维护困难等问题,设计了基于STM32微控制器的冷藏集装箱微环境控制系统的串行通信子系统。介绍了该串行通信子系统的构成,分析了基帧识别、收发处理、轮询机制、有限状态机等设计方法及程序实现。测试结果表明,该系统实现了冷藏集装箱环境控制系统的分散控制与集中管理,简化了系统结构,方便维护,且效果良好。
The various parameters and the links centrally are controlled by a single controller in the traditional reefer container environ- ment control system,so the system structure is complex,non modular, and is difficult to install and maintain. So a serial communication subsystem of the micro environmental control system in reefer container based on STM32 microcontroller is designed. In the paper, the structure of the system is introduced,the design methods and program implementation of frame identify, sending and receiving process ing,polling mechanism, finite state machine of the communication subsystem is analyzed. The test results prove that the system achieves decentralized control and centralized management in the environmental control system in reefer container, it simplifies the system archi- tecture and makes it more convenient to maintain.
