摘 要：石油勘探开发测井过程中，要实时监控电缆承受的张力，测井施工中通常在井口天滑轮上挂接张力计，利用通讯电缆连接张力计和测井工程车上的采集系统对电缆张力进行测量和监控。通讯电缆在施工过程中，不论井口还是地面会经常受到钻具等钻探工具设施的碰撞挤压而损坏，为了避免施工中发生此类问题而耽误工时，施工人员提出无线传输张力的方案。张力的采集和无线传输采用模块化设计，利用Modbus 传输协议根据实际情况设置采集速度。工程车上配置控制用的工控机，把张力信号恢复成兼容原来绞车面板的模拟量，工控机内安装的控制软件能根据实际灵活配置串口及电池电压监控。

Abstract：During the oil exploration and development logging process，the tension of the cable should be monitored in real time.In the logging construction，the tension meter is usually attached to the wellhead pulley，and the communication cable is used to connect the tension meter and the collection system on the logging truck. Tension is measured and monitored. During the construction process，the communication cable is often damaged by the collision of drilling tools such as drilling tools at the wellhead or the ground. In order to avoid such problems during construction，the construction workers propose a wireless transmission tension scheme. The tension collection and wireless transmission adopt modular design，and the acquisition speed is set according to the actual situation by using the Modbus transmission protocol. The industrial computer equipped with control on the engineering vehicle restores the tension signal to the analog quantity compatible with the original winch panel. The control software installed in the industrial computer can flexibly configure the serial port and battery voltage monitoring according to the actual situation.
