The invention relates to an included angle measuring system which comprises a plurality of signal transmitters, a plurality of signal receivers and a processing unit. The plurality of signal transmitters are fixed relative to the trailer; the plurality of signal receivers are arranged on the tractor; the processing unit is configured to determine the distance between the plurality of signal receivers and each signal emitter according to the detection signals between the plurality of signal receivers and the plurality of signal emitters; and the steering included angle between the tractor and the trailer is calculated according to the distances from the signal receivers to the signal emitters, the distances among the signal emitters and the distances among the signal receivers. Therefore, on one hand, the signal receiver and the signal emitter are both located outside the saddle and are convenient to assemble and disassemble; on the other hand, the problem that optical ranging cannot beused at night can be effectively solved; on the other hand, the steering included angle is obtained through accurate distance measurement calculation of the sensor, and compared with a traditional included angle measuring device, accuracy and stability are higher. The invention further provides traction transportation equipment.
本发明涉及一种夹角测量系统,包括多个信号发射器、多个信号接收器及处理单元;多个信号发射器相对挂车固定;多个信号接收器装设于牵引车;处理单元被配置为根据多个信号接收器与多个信号发射器之间的检测信号确定多个信号接收器到每一信号发射器之间的距离,并根据信号接收器到信号发射器之间的距离、多个信号发射器彼此之间的距离和多个信号接收器彼此之间的距离计算牵引车与挂车之间的转向夹角。这样,一方面信号接收器与信号发射器均位于鞍座外部,便于装拆;另一方面,可以有效解决光学测距夜间无法使用的问题;又一方面,通过传感器精确测距计算获得转向夹角,相比传统的夹角测量装置精确性及稳定性更高。还提供一种牵引运输设备。
