Electromagnetic Environment of Industrial Frequency Intelligent Monitoring System in City

The system is used to monitor electromagnetic environment of industrial frequency in city for eliminating industrial frequency radiation to harm people. The system can automatically acquire, memorize, analyze and manage measurement data. Data acquisition instrument was composed of anterior analog circuit, control circuit, data acquisition and memory, communication module. Interface in PC was realized with LabVIEW. A mass of actual measurement data was acquired and measurement precision accorded with request that don't exceed 6%. The system can operate normally in wicked environment and is low loss of power rating. Moreover, it is fit for distributed and remote monitoring
