Embodiment 1

[0026] A monitoring and alarming method for advance detection of roadway based on laser ranging, comprising the following steps:

[0027] a. Prepare, input to the central processor and set the safe excavation distance for advance water exploration in the roadway, and send a signal to adjust the angle of the laser rangefinder, and align the laser rangefinder with the measurement target;

[0028] b. Start, receive the laser rangefinder adjustment signal, start and stop the laser rangefinder, the light wave signal is sent out to the target, and the laser rangefinder will automatically receive the reflected echo signal;

[0029] c. Judgment: Receive the actual distance parameter measured by the laser rangefinder, compare the actual distance parameter with the safety tunneling distance parameter set in step a, and judge whether to send an alarm signal according to the comparison result. If the measured distance parameter is less than the set roadway advance water detection safety e...

Abstract

The invention relates to the technical field of automatic control, specifically to a tunnel advanced detection monitoring alarming method and apparatus based on laser range finding. The method includes the steps of a, preparation step including setting tunnel advanced water probing safety driving distance, sending a signal for adjusting the angle of a laser range finder, and aligning the laser range finder with a measurement target, b, starting step including receiving the properly adjusted signal of the laser range finder, and starting and stopping the laser range finder, c, determination step including receiving the actual distance parameter measured by the laser range finder, comparing the actual distance parameter with the tunnel advanced water probing safety driving distance set in step a, and determining whether to sent an alarm signal according to the comparison result, giving off an alarm signal when the measured distance parameter is smaller than the tunnel advanced water probing safety driving distance set in step a and locking the power supply of the tunnel driving working face, and d, information storage step including measuring, recording and storing the tunnel drilling footage of each working shift, each day and each month.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a monitoring and alarming method and device for roadway advanced detection based on laser ranging. Background technique [0002] In the process of water exploration and excavation in coal mine roadways, the requirements for the safety distance are very strict. The "Coal Mine Safety Regulations" stipulates that there must be excavation and exploration, that is, the excavation and discharge operations must be carried out before excavation. When the excavation length is about to reach the safe excavation distance, the next round of excavation and discharge operation must be carried out to determine the new roadway excavation safety distance, and the safe excavation distance must not be exceeded. This process is difficult to grasp. Violation of the safety red line of "everything must be explored". Contents of the invention [0003] In order to solve the technical problem...
