Automatic coal unloading system and method of hopper car based on photoelectric correlated sensor technology

Abstract

The invention discloses an automatic coal unloading system of a hopper car based on a photoelectric correlated sensor technology. The automatic coal unloading system of the hopper car based on the photoelectric correlated sensor technology comprises a photoelectric correlated sensor unit, an execution unit and a control terminal (13), wherein the photoelectric correlated sensor unit comprises supports (5); an optoelectronic switch illuminator (4) is arranged at the top end of one support (5); an optoelectronic switch photoelectric receiver (6) is arranged at the top end of the other support (5); and the execution unit comprises a bottom door opening and closing mechanism (7), a first door opening and meeting device (8) and a second door opening and meeting device (9). The invention furtherdiscloses an automatic coal unloading method of the hopper car based on the photoelectric correlated sensor technology. According to the automatic coal unloading method of the hopper car provided bythe invention, the photoelectric correlated sensor technology is adopted, and the illuminator and the photoelectric receiver arranged at appropriate positions of two sides of a walking track of the bottom-opened hopper car form a correlated separating type optoelectronic switch, so that the bottom door opening and closing mechanism of the bottom-opened hopper car is opened, and coals can be automatically and efficiently unloaded.

Description

technical field [0001] The invention belongs to the technical field of hopper car door opening control, and more specifically relates to a hopper car automatic coal unloading system and method based on photoelectric cross-beam sensing technology. Background technique [0002] In order to improve the unloading efficiency of the bottom-opening hopper car, the coal unloading system is equipped with multiple coal unloading chutes, and the coal in different compartments of the hopper car can fall into different coal unloading chutes by controlling the regular opening of the door-opening head-to-head device. [0003] At present, there are two common control systems: one is the hopper car automatic unloading control system based on electromagnetic induction technology, which reads the vehicle information through the card reader to control the regular opening and closing of the door opening and meeting equipment, but it needs to be attached to the car. Different labels, when the veh...

[0003] At present, there are two common control systems: one is the hopper car automatic unloading control system based on electromagnetic induction technology, which reads the vehicle information through the card reader to control the regular opening and closing of the door opening and meeting equipment, but it needs to be attached to the car. Different labels, when the vehicles are regrouped, it is necessary to relabel the vehicles or change the label type, the workload is heavy, and it is easy to make mistakes. If the label sequence management is not performed on the grouped vehicles, the label sequence will be confused and affect the normal opening and closing; one is Taking advantage of the fact that the distance between adjacent wheels is a fixed value, a fixed-distance proximity switch is set on the rail. The proximity switch and supporting facilities are close to the ground, which is easily affected by the environment. The system is complex and the reliability is not high.
