The invention provides a high-low crane automatic electrical control system and control method, and belongs to the technical field of electrical control. The high-low crane automatic electrical control system comprises a controller unit, a display unit, a sensor unit, a wireless transmission unit and a safety protection unit. The controller unit obtains the attitude of a box girder in hoisting according to an inclination angle sensor in the sensor unit, obtains the RTK space coordinate position of the head end and the tail end of the box girder according to a winch height encoder and a crown block stroke encoder, checks and resets the RTK position of a crown block in operation through an RFID position reader, calculates the RTK space coordinate position of the box girder and compares the RTK space coordinate position with a target value, the box girder is controlled to be lifted according to the difference value, automatic box girder lifting is achieved, the control precision is higher, the labor cost is reduced, and meanwhile the construction efficiency is improved; and the safety protection unit is used for guaranteeing that a certain safety distance is kept between the beam endand other objects, collision and scratching are prevented, the controller unit can control equipment to stop in time when an alarm is given, and construction safety is guaranteed.

    本发明提供了一种高低吊自动化电气控制系统及控制方法,属于电气控制技术领域,包括控制器单元、显示单元、传感器单元、无线传输单元和安全保护单元。控制器单元依据传感器单元中倾角传感器获得箱梁吊装中的姿态,依据卷扬机高度编码器和天车行程编码器获得箱梁首尾端的RTK空间坐标位置,并通过RFID位置读取器校核重置天车运行中的RTK位置,计算箱梁的RTK空间坐标位置并与目标值比较,根据差值控制箱梁提升,实现自动化箱梁吊装,控制精度更高,减少了人工成本,同时提高了施工效率;安全保护单元用于保证梁端与其他物体保持一定的安全距离,防止发生碰撞刮蹭,发生报警时控制器单元能够及时控制设备停机,保证施工安全。
