Moving-block technology-based method for dividing underground narrow-gauge track block section

Abstract

The invention relates to a moving-block technology-based method for dividing an underground narrow-gauge track block section. The method comprises the following steps of dividing all tracks in an underground station of a mine into a plurality of basic track section units in advance; enabling an infrared positioning transmitter on the outer side of a headstock of a locomotive to emit infrared data with a locomotive number coded message in real time; after infrared positioning receivers arranged on two sides of an underground roadway receive the infrared data with the locomotive number coded message, enabling the infrared positioning receivers to feed the data back to a dispatcher control center; enabling the dispatcher control center to judge the state of a track section in which the locomotive runs according to the position of the locomotive and to automatically perform locking and unlocking control over the track to dynamically divide the track block section. The method replaces the traditional method for dividing an underground narrow-gauge track fixed section, the locomotive dispatching flexibility and the mine transporting efficiency of the underground locomotive are improved, the maintenance and the loss of equipment are reduced, the method is subjected to small influence of environmental factors and the underground safety transportation is guaranteed.

Description

technical field [0001] The invention relates to a division method of underground narrow-gauge track sections based on infrared communication technology, in particular to a division method of underground narrow-gauge track block divisions based on moving block technology. Background technique [0002] Since 2005, the output of domestic non-coal mines has increased year by year, and small mining areas have gradually been integrated into large and medium-sized mines. And with the gradual reduction of open-pit mining, underground mining has gradually increased. The output of a single mine has increased significantly, and the use of tramcars to transport ore rocks has become the choice of most mines. However, the current transportation capacity of tram locomotives has been unable to reach the ore output level, thus restricting the total output of underground mines and becoming an intermediate bottleneck in the entire process. To maximize the transportation effect, it is particu...

AI Technical Summary

Problems solved by technology

However, due to poor working conditions in underground mines and special track conditions, the way of using locomotive wheels to locate locomotives through track circuits or track axle counters is too rigid, and the equipment is frequently damaged and requires a lot of maintenance.

However, the method of using wireless on-board equipment on locomotives to realize wireless communication positioning is not suitable for underground applications in mines where the strength of wireless signals is unstable, and driving safety is difficult to be guaranteed.
