Intelligent electric locomotive collision-prevention system

Abstract

The invention discloses an intelligent electric locomotive collision-prevention system, which consists of an infrared emission unit, an infrared receiving unit, a master control unit, an execution unit, a sound and light alarming unit and a hydraulic brake unit, wherein the master control unit mainly comprises a singlechip IC (AT89C2051); the infrared receiving unit is connected with the input end of the singlechip; and one path of the output end of the singlechip is connected with the sound and light alarming unit and a hydraulic oil pump, while the other path controls the opening of a proportional electromagnetic valve. The intelligent electric locomotive collision-prevention system has a simple structure and rational design, and can automatically realize fast and stable stop before theoccurrence of collision risks, completely avoid electric locomotive collision accidents in the underground rail haulage process of a coal mine, greatly reduce economic loss and social impact caused by the accidents and improve the security coefficient and production efficiency of the coal mine.

Description

technical field [0001] The invention relates to a motor vehicle safety device, in particular to an electric locomotive anti-collision system in a mine underground horizontal roadway. technical background [0002] With the rapid development of the coal industry and the continuous rise of the coal market, the underground roadway transportation closely related to the production of raw coal in coal mines is becoming more and more heavy. Usually, measures such as increasing the number of transport vehicles and trains, or increasing the speed of vehicles are adopted to adapt. However, it also brings many unfavorable factors and potential safety hazards, especially because the driver of the electric locomotive is inattentive, unresponsive, makes mistakes in observation and judgment or is tired and drowsy, irresponsible, and the dislocation of the switch, and the switch is cut by mistake. Head-on collisions and rear-end collisions of rail transport electric locomotives occur frequen...

AI Technical Summary

Problems solved by technology

However, due to the special environment of the coal mine underground, the roadway is narrow, the rail surface is wet, and there are many bends in the branch road, the maximum distance between the roadway wall and the rail is less than 1 meter.

When the electric locomotive travels to a curve or fork, the electromagnetic wave or light emitted by the transmitter installed on the electric locomotive is easily reflected by the wall of the roadway or passing vehicles on the road, causing false alarms and malfunctions of the brake device.

Secondly, the braking device is braked by mechanical mechanisms such as hand brakes and motor levers. The reaction speed may be slow or fast, and the braking is not stable. It is also easy to cause the vehicle to fall off the road or damage the equipment, and even cause personal injury

Therefore, this type of braking device is not suitable for underground coal mines, and may also leave potential safety hazards.
