Obstacle sensing and anti-collision system of self-propelled monorail conveyor

The utility model relates to agricultural machinery and electrical control technology, in particular to an obstacle sensing and anti-collision system of a self-propelled monorail conveyor. Comprising a first laser radar, a second laser radar, a data conversion unit, a first ultrasonic probe, a second ultrasonic probe, an appropriate ultrasonic probe, a fourth ultrasonic probe, an ultrasonic ranging unit, a controller, a first electric pull rope, a second electric pull rope, an accelerator mechanism and a brake mechanism. The first laser radar and the second laser radar are electrically connected with the data conversion unit through wires. The first ultrasonic probe, the second ultrasonic probe, the third ultrasonic probe and the fourth ultrasonic probe are electrically connected with the ultrasonic ranging unit through wires. The system controls the accelerator mechanism and the brake mechanism to act according to the laser radar ranging information and the ultrasonic ranging information. When the self-prope
