The invention provides a multifunctional distance measuring device for a substation operation crane, which is mounted on a crane body and comprises a vehicle-mounted module and a ground analysis display module which communicate with each other, the vehicle-mounted module is used for sensing electric field signals around specified electrified equipment under the operation condition of the operation crane, carrying out signal preprocessing and data calculation on the electric field signals, and further sending obtained calculation result data to the ground analysis display module; the ground analysis display module displays the received result data and preset threshold data; and comparing the received result data with the threshold data, judging whether the operation of the operation crane is safe or not according to a comparison result, and further giving an alarm when it is judged that the operation of the operation crane is unsafe. The device is simple in structure, convenient to operate, time-saving and labor-saving, and capable of measuring whether the operation crane and the electrified equipment are safe or not and preventing the problem that the safe distance is insufficient.

    本发明提供一种用于变电站作业吊车的多功能测距装置,安装于包括吊车本体、包括相互通信的车载模块和地面分析显示模块;车载模块在作业吊车的操作工况下,感应指定带电设备周边的电场信号,且对电场信号进行信号预处理及数据计算,进一步将所得计算结果数据发送给地面分析显示模块;地面分析显示模块显示接收到的结果数据和预先设置阈值数据;以及,将接收到的结果数据与阈值数据进行对比,并根据对比结果,判断作业吊车的操作是否安全,且进一步在判断出不安全时,进行报警。实施本发明,结构简单,操作方便且省时省力,能衡量出作业吊车与带电设备之间是否安全,并对安全距离不足问题进行防范。
