摘　　要：针对目前油田采油车自动化程度低和局部操作不方便等缺点, 从更好地控制采油车的整个工作过程出发, 开发了一种较先进的采油车自动监控系统。该系统可实时显示起下载荷、深度、速度; 使用霍尔传感器可测得滑轮转速; 利用单片机可计算得到下入深度或上升距离; 通过使用应变测量技术测得钢丝绳的张力, 可计算出载荷大小。控制箱是该系统的核心部件, 它与气控执行部分相连, 可实现对刹车、离合器的控制, 并能根据各使用方所要求的不同参数, 更改程序相关参数, 实现对采油车的灵活控制。Since the existing trailer mounted pumping unit is inconvenient to operate, an automatic monitoring system is developed. The system can make a real time display of the load, depth and velocity. Hall sensor is adopted to measure the rotary speed of the pulley; singlechip computer is used to compute the depth of setting and rising distance of the pump; strain measuring technique is used to test the tensile force of the wireline, so the load computation can be accomplished. As the core component of the system, the control cabinet is connected with the pneumatic control executive part, and can carry out the control of the brake and clutch.
