摘要
介绍一种基于单片机AT89S8252与PSTN通信接口电路组成的远程监测系统,该系统具有可视化、安全、高效等特点。选用具有复位功能和看门狗定时器的MAX232,提高单片机的稳定性和抗干扰能力,保障了系统的可靠运行。通过上、下位机主从结构设计,从而实现定时和随机两种方式对工业排放废气参数的有效远程监控,为环保质量监测部门对工业排污提供了一种有实际应用价值的监测系统。
In the paper,a kind of remote monitoring system was made up of MCU AT89S8252 and interface circuit is introduced,the system has characteristics of visualize, safe and reliable. Using MAX232 can restore to the position and has watch dog timer function to improve the stabilty. The system has been ensured normal running. It is designed by above - vice construct,the waste-vapor of indstruit can be checked by the mannals of setting timer and freedom. The monitoring system has reality faciity.
