Design of Automatic Monitoring System for Weak Power Grid Based on Single Chip Computer

传统的自动监控系统存在输出时延的问题,为此设计一种基于单片机的弱电网自动监控系统。首先,定义弱电网运行的MFCC参数,并使用系统自动监控服务器与传感器提取运行数据;其次,将获取的信息导入前端,同步使用计算器将数据频率转换成数据量;最后,采集弱电网运行电压、电流与阻抗,将获取的数据通过GPRS传输到系统传感器终端,以此完成对弱电网运行的自动监控与预警。实验结果表明,设计系统时延较短,具有实用性。

The traditional automatic monitoring system has the problem of output delay,so a weak current network automatic monitoring system based on MCU is designed.Firstly,define the MFCC parameters of the weak current network operation,and use the system automatic monitoring server and sensor to extract the operation data;Secondly,the acquired information is imported into the front end,and the calculator is used synchronously to convert the data frequency into data volume;Finally,the operation voltage,current and impedance of the weak current network are collected,and the obtained data are transmitted to the sensor terminal of the system through GPRS,so as to complete the automatic monitoring and early warning of the weak current network operation.The experimental results show that the designed system has short delay and practicability.
