Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the automatic empty and heavy loading detection system for the container comprises an editable logic controller (PLC)1, a TOF laser ranging sensor 2, a rail pressure sensor 3 and an empty and heavy loading alarm 4 which are respectively connected with the PLC 1; the PLC 1 is connected with the empty and heavy mixed alarm 4 through a wired or wireless communication module;

as shown in fig. 2, the rail pressure sensor 3 is arranged on a sleeper C, the sleeper adjacent to the sleeper C is a sleeper B, the two sleepers adjacent to the sleeper B are respectively a sleeper C and a sleeper a, two ends of a force transmission rod 5 extending along the axial direction of the rail are respectively positioned on the sleeper a and the rail pressure sensor 3, the force transmission rod 5 is fixed on the sleeper B and the sleeper a, the rail right above the sleeper C is a rail Gb, the rail right above the sleeper B and the sleeper a is a rail Ga, a gap is reserved between the rail Ga and the rail Gb, the rail Ga and the rail Gb are fixedly connected by a clamping plate 6, and as the two rails Ga and Gb are fixed by the clamping plate 6, when the rail Ga descends, the rail Ga only applies partial pressure due to the existence of the gap between the two rails Ga and Gb, and the whole detection data is not greatly influenced;

along the advancing direction of a vehicle on a track, the TOF laser ranging sensor 2 is arranged on the front side of the track pressure sensor 3, a probe of the TOF laser ranging sensor 2 horizontally faces to the right upper side of the track, and the distance between the TOF laser ranging sensor 2 and the track pressure sensor 3 in the axial direction of the track is equal to the horizontal distance between the vehicle head and the front wheel of the vehicle.
