Speed monitoring and capturing system and method for inclined roadway transportation mine car

Abstract

The invention discloses a speed monitoring and capturing system and method for an inclined roadway transportation mine car. The speed monitoring and capturing system comprises a speed monitoring unitand a sports car capturing unit. The speed monitoring unit comprises a monitoring box, a mounting bracket and a camera, a circuit board and a power supply circuit module are arranged in the monitoringbox, and a video acquisition and transmission circuit integrated on the circuit board comprises a microprocessor module, a data storage circuit module, a wireless communication module, a USB interface circuit module and a sound-light alarm circuit module. The sports car capturing unit comprises a supporting frame, a slope speed reduction plate, a PLC controller , a first double-lifting-point electric hoist and a second double-lifting-point electric hoist. Two wheel braking mechanisms are arranged on the slope speed reduction plate. The speed monitoring and capturing system is convenient to install and maintain, can be applied to inclined roadway transportation, can monitor the speed of a mine car in real time, achieves safe and stable capturing of the running car in combination with the running car capturing unit, prevents serious consequences, and is convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety production, and in particular relates to a speed monitoring and capturing system and method for mine vehicles transported in inclined lanes. Background technique [0002] Coal has been mined as an important resource in my country for a long time, but most of the coal resources are buried deep underground. The biggest safety hazard in alley transportation is the occurrence of sports car accidents. The so-called sports car accident refers to the loss of control of the mine car used for lowering equipment, lifting materials, transporting coal or personnel in coal mines due to short ropes, broken chains or misoperation. Under the action of its own gravity component, the accident caused by the abnormal operation of the mine car along the track. Therefore, the importance of the anti-car device is self-evident. In the prior art, in order to solve the serious consequences of sports car accidents ...

AI Technical Summary

Problems solved by technology

In the prior art, in order to solve the serious consequences of sports car accidents in inclined lane transportation, many researchers and engineers have proposed a variety of solutions, such as the anti-sports car device in the invention patent with application number 201721864746.2, which is installed on the mine car track The anti-sports car blocking assembly and the anti-sports car retractable winch assembly, but its structure is huge and complex, the location of the sports car is unknown, and multiple anti-sports devices need to be installed in the inclined lane, and the structural complexity of a single anti-sports device increases its installation cost , which limits its wide application; another example is the anti-car device in the invention patent with the application number 201510908805.0, which includes the speed acquisition component, hydraulic drive system and track capture component installed on the mine car. To prevent the occurrence of sports car accidents, but its structure is also relatively complex. The individual sports car accidents are unknown, and it is necessary to install an anti-sports car device on each sports car. Similarly, the complexity of its structure increases the installation cost and limits its wide application
