Multi-terminal remote monitoring and early warning system based on STC89C52 MCU

为了克服远距离作业与危险作业等问题,提出了基于STC89C52单片机与无线通信技术的多终端远程监测预警系统。系统以单片机STC89C52为核心,对各数据采集终端电路进行独立设计,可根据实际需要采用多组传感测量装置对不同位置环境参数进行实时监测,包括温度数据和湿度数据。采集的数据信息由无线收发模块KYL1020U完成远距离传输,通过与PC机之间的串口通信将多路数据信息进行实时显示与处理,起到远程监测和预警作用。该测试系统结构简单,使用方便,具有实时性与高可靠性等特点,能够满足用户实际使用要求。

In order to overcome the problems of remote operation and dangerous operation, a multi terminal remote monitoring and warning system based on STC89C52 and wireless communication technology is proposed in this paper. With STC89C52 micro-controller as the core, with the independent circuit design for data acquisition terminal, the system adopts the multiple sensing and measuring device to have real-time monitoring of the different position of the environment parameters according to the actual needs, including temperature and humidity data. Long distance transmission of data information is completed by wireless transceiver module KYL1020U and multi-information is transported to PC by serial communication to achieve real-time displaying and processing. The test system proposed has characteristic of simple structure, easy use, real-time performance and high reliability to meet users requirement.
