A speed monitoring and capturing system and method for transporting mine cars in inclined lanes

Abstract

The invention discloses a speed monitoring and capturing system and method for transporting mining vehicles in inclined lanes. The speed monitoring and capturing system includes a speed monitoring unit and a sports car capturing unit; the speed monitoring unit includes a monitoring box, a mounting bracket and a camera, and a There is a circuit board and a power supply circuit module. The video acquisition and transmission circuit integrated on the circuit board includes a microprocessor module, a data storage circuit module, a wireless communication module, a USB interface circuit module, and an audible and visual alarm circuit module; the sports car capture unit includes a support frame, The slope deceleration plate, the PLC controller, the first electric hoist with double lifting points and the second electric hoist with double lifting points, and two wheel braking mechanisms are arranged on the slope deceleration plate. The speed monitoring and capture system of the present invention is easy to install and maintain, and can be applied in inclined lane transportation to monitor the speed of mine cars in real time, combined with the sports car capture unit, to realize safe and stable capture of sports cars, prevent serious consequences, and facilitate popularization 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
