基于Wi-Fi通信的工频电场测量系统设计

Design of power frequency electric field measurement system based on Wi-Fi communication

现有的工频电场测量仪通常采用光纤作为数据传输介质,光纤系统结构复杂、成本较高。测量人员手持终端与电场探头之间由光纤连接,无法实现人机分离,给测量带来不便。该文设计了一种基于Wi-Fi通信的工频电场测量系统,通过Wi-Fi无线连接方式实现工频电场测量数据的传输,可避免因测量人员离测量点太近而带来的电场畸变影响,保障现场工频电场测量的准确性。工频电场测量结果可以在现场带有Wi-Fi功能的移动终端上显示,也可以上传至云服务器,供后台工作人员实时监测和分析,实现人机分离以及数据的不间断传输。

Optical fiber is usually used as data transmission medium in existing power frequency electric field measuring instruments.Optical fiber system has complex structure and high cost.The optical fiber is used to connect the hand-held terminal with the electric field probe.It cannot realize man-machine separation,which brings inconvenience to the measurement.This paper designs a power frequency electric field measurement system based on Wi-Fi communication.The system realizes the transmission of power frequency electric field measurement data through Wi-Fi wireless connection,which can avoid the influence of electric field distortion caused by the measurement surveyor who is too close to the measurement point,and can ensures the accuracy of field power frequency electric field measurement.The measurement results of power frequency electric field can be displayed on the mobile terminal with Wi-Fi function in the field,and can also be uploaded to the cloud server for real-time monitoring and analysis,thus realizing man-machine separation and uninterrupted data transmission.
