基于RS-485总线的水族箱控制器远程通信的实现

通过对目前大多数水族箱控制器应用现状的分析，说明单个水族箱控制器存在无法实现远程控制和管理的不足，在充分研究远程通信设计的基础上，采用基于485通信总线的上下位机通信结构，实现了远程通信的硬件电路的设计，提出了主从通信协议的数据格式、波特率和通信方式等，并完成了上下位机的程序流程图的设计，阐述了程序核心模块的设计思路，最终实现对多台水族箱控制器的远程控制和管理。

The Realization of the Remote Communication between PC and the Controller in Aquarium Based on RS-485 Bus

The paper analyzed most of the aquariums controller currently applied, explained the deficiency that a single controller of the aquariums is unable to realize the long-distance control and the inefficient management exists. The communication structure based on 485 buses between one-chip computer and PC is proposed, the hardware circuit in remote communication designed, the data form, baud rate and the way of the communication protocol proposed, the procedure flowchart of the communication between one-chip computer and PC designed, the designing of the procedure core modules explained, and finally the remote control and management of many aquariums are realized.
