Problems solved by technology

[0004] Currently the mileage of mining equipment cannot be directly and accurately measured
The commonly used method is to measure the depth through the odometer installed on the walking track. Because the track often slips and the floating coal around the track is serious, it has a great impact on the accuracy of the depth measurement, making the measured depth value and the real value. The difference is large, the accuracy is poor, and it is impossible to grasp the position of the mining equipment in the roadway

Abstract

The invention discloses an excavation equipment depth measurement method based on a total station, which combines an inertial navigation unit with the total station, gives the forward direction of the equipment through the inertial navigation unit, gives the accurate positioning of the equipment through the total station unit, and realizes the roadway depth measurement of the excavation equipment through the mutual cooperation of the inertial navigation unit and the total station unit. As the inertial navigation unit and the total station unit have strong adaptability to the environment and have no limitation on equipment types, the method can be used for various equipment such as a slope continuous miner, a heading machine and the like, and is wide in application. And through real-time depth data, an operator can remotely obtain the position of the equipment in a roadway, and follow-up actions of the operator on the excavation equipment are facilitated.

Description

technical field [0001] The invention relates to the technical field of underground excavation, in particular to a method for measuring the depth of excavation equipment based on a total station. Background technique [0002] As an important equipment in the mechanized production process of fully mechanized excavation, mining equipment is widely used in coal mine roadway mining and road tunnel construction. my country's coal mine mining face is highly dangerous and dusty, which is not conducive to the production labor and safety and health of on-site workers. With the popularization and application of computer technology, environmental perception technology, data fusion technology and intelligent algorithm, the remote control of mining equipment and unmanned working face become the inevitable requirements of future development. [0003] To realize remote control of mining equipment and unmanned working face, it is necessary to accurately obtain the real-time position of the ...
