The division method of underground narrow-gauge track block partition based on moving block technology

Abstract

The present invention relates to a method for dividing blocks of underground narrow-gauge track blocks based on mobile block technology. All tracks in the mine underground station are divided into several basic track section units in advance, and an infrared positioning transmitter installed outside the locomotive head Transmit infrared data with "vehicle number code information". When the infrared positioning receivers installed on both sides of the underground roadway receive the infrared data information with "vehicle number code information", the data will be fed back to the dispatch control center. The control center judges the status of the locomotive running position and track section through the position of the locomotive, automatically locks and unlocks the track, and completes the dynamic division of the track block zone. It replaces the traditional way of dividing the fixed section of narrow-gauge underground track, improves the flexibility of locomotive dispatching and the efficiency of mine transportation of underground locomotives, reduces the amount of maintenance and loss of equipment, is less affected by environmental factors, and ensures underground safety transportation.

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.
