Safe pointing and safe distance real-time monitoring system

Abstract

The invention relates to a safe pointing and safe distance real-time monitoring system which comprises a laser pointing distance measuring instrument, a ground host computer and a data transmission system, wherein the data transmission system is used for the communication between the laser pointing distance measuring instrument and the ground host computer. The laser pointing distance measuring instrument comprises a laser transmitter, a laser receiver, a laser pointing module, a laser distance measuring module, a central control unit, a communication module, a time control module and a power supply module, wherein the power supply module is used for supplying power for all the parts. The system is also provided with a video camera and a wireless control device. The invention can realize the automatic pointing in a tunneling direction and the automatic real-time monitoring of a tunneling distance, not only can save the manpower, but also can improve the production efficiency, and can realize the combined monitoring of data and images, the wireless control of a working spot and the remote control working of ground managers.

Description

technical field [0001] The invention relates to a system for pointing and ranging in tunnel and mine excavation engineering, in particular to an automatic control system capable of realizing safe pointing and safe distance monitoring. Background technique [0002] In coal mine excavation engineering, the excavation direction and excavation distance of the roadway are two important technical parameters related to engineering safety and engineering progress. For example, if the direction of the excavation is wrong, it will affect the progress of the project at least, and at the most, it will easily lead to false penetration of the multi-headed excavation of the roadway; if the excavation distance is not well controlled, it will easily cause dangers such as entering water areas, old empty areas, and gas outburst coal seams. The area puts the entire mine and personnel in a dangerous situation, and the inaccurate control of the water exploration position may cause floods, causing...

Problems solved by technology

[0004] With the improvement of the mechanization level of coal mine excavation engineering in recent years, the excavation speed has been greatly accelerated. Although the corresponding measuring instruments have been introduced in the process of laser pointing and laser ranging, the construction speed has been improved to a certain extent, but the manual work in this process The amount is still very large, and the laser pointing and laser ranging are carried out separately by two instruments. As the excavation continues, the installation positions of the above-mentioned detection instruments need to be changed frequently, so the installation workload is heavy. Adapt to the tunneling speed, and cannot guarantee the effective measurement and timely grasp of the measured parameters, let alone effective control
