Self-adaptive segmented power supply system and method for one-way track of coal mine tunnel

Abstract

The invention provides a self-adaptive segmented power supply system for a one-way track of a coal mine tunnel. The self-adaptive segmented power supply system comprises a power supply and signal control box, power supply lines and an acousto-optic alarm. A vehicle-mounted annunciator is arranged on an electric locomotive. The self-adaptive segmented power supply system is characterized in that the power supply and signal control box comprises a microcontroller and a high-voltage direct-current contactor, wherein the high-voltage direct-current contactor is used for controlling the on-off state of the corresponding power supply line; the vehicle-mounted annunciator comprises a wireless signal receiving and sending module and a signal indicator light used for indicating whether an electric locomotive appears. A control method of the self-adaptive segmented power supply system comprises the steps that (a) a communication distance is set; (b) whether an electric locomotive travels into the one-way track is judged; (c) power is supplied to the corresponding power supply line; (d) an alarm signal is sent out; (e) power supplied to the other power supply lines is cut off; (f) whether the electric locomotive travels to the destination is judged. By means of the self-adaptive segmented power supply system and the control method, segmented power supply to the electric locomotive is realized, and an electric shock accident is avoided; the acousto-optic alarm can be used for giving a warning when other electric locomotives travel in the one-way track, and therefore a collision accident is avoided.

Description

technical field [0001] The present invention relates to a coal mine roadway single track power supply system and method, more specifically, to a coal mine roadway single track power supply system and method for segmented power supply according to the position of an electric locomotive. Background technique [0002] At present, the power supply of electric locomotives in coal mines mostly uses high-voltage and high-current power supply. The height of the roof layer of the roadway limits the height of the wires. There are certain safety hazards when the coal mine workers travel in the roadway. If the cable touches, an electric shock will occur, which may easily cause personal injury or death. Moreover, most of the transportation tracks in the roadway are monorail transportation. Since there is no linkage signal system, it is easy for locomotives traveling in opposite directions to meet on the single-track line, causing unnecessary troubles, wasting a lot of manpower and mater...

[0002] At present, the power supply of electric locomotives in coal mines mostly uses high-voltage and high-current power supply. The height of the roof layer of the roadway limits the height of the wires. There are certain safety hazards when the coal mine workers travel in the roadway. If the cable touches and causes electric shock, it is easy to cause personal injury or death

Moreover, most of the transportation tracks in the roadway are monorail transportation. Since there is no linkage signal system, it is easy for locomotives traveling in opposite directions to meet on the single-track line, causing unnecessary troubles, wasting a lot of manpower and material resources, and leaving behind for collisions.
