Gyroscope for positioning engineering vehicle in tunnel

Abstract

The invention provides a gyroscope for positioning an engineering vehicle in a tunnel, and relates to the technical field of micro-mechanical voltage type gyroscopes. The gyroscope comprises a micro-mechanical voltage type gyroscope body, an auxiliary monitoring projection is arranged on the peripheral surface of the micro-mechanical voltage type gyroscope body adjacent to the left side of a socket, and the auxiliary monitoring projection is of a rectangular block structure; and a storage clamping groove is formed in the front end surface of a baffle plate at the socket end of the micro-mechanical voltage type gyroscope body. According to the invention, whether a fixing bolt of the micro-mechanical voltage type gyroscope body is loosened or not and whether a plug and the socket of the micro-mechanical voltage type gyroscope body are loosened or not are monitored in real time. Therefore, the situation that the acceleration and the direction are detected mistakenly due to unstable installation or unstable connection of the micro-mechanical voltage type gyroscope body is effectively avoided, and the problem that the acceleration and the direction are detected mistakenly and easily and the accurate positioning of the construction vehicle is influenced due to unstable installation or unstable connection of the micro-mechanical voltage type gyroscope body is solved.

Description

technical field [0001] The invention relates to the technical field of micro-mechanical voltage gyroscopes, in particular to a gyroscope used for positioning engineering vehicles in tunnels. Background technique [0002] When building a tunnel, the construction vehicles in the tunnel cannot be accurately positioned by GPS, so the acceleration and acceleration direction of the micro-mechanical voltage gyroscope are used to simulate the speed. position to achieve higher precision vehicle positioning. [0003] However, once the fixing bolts of the MEMS gyroscope become loose due to bumps and other factors in the tunnel or the socket between the plug and the MEMS gyroscope becomes loose, the driver cannot know in time, because the MEMS gyroscope is installed Instability or connection instability can easily lead to wrong detection of acceleration and direction, affecting the precise positioning of construction vehicles. Contents of the invention [0004] In view of this, the ...
