Automatic Perception System of Personnel Approaching in Mine Underground Motor Vehicles

Abstract

The invention relates to an automatic proximity perception system for mining downwell motor vehicles and personnel, which comprises the components of labels that are worn on the bodies of personnel, base stations which are mounted on the vehicles, a server, a time synchronizer, a label control module and a vehicle control alarm module. The server is connected with the time synchronizer, the label control module, the vehicle control alarm module and each base station. The time synchronizer is connected with each base station through a cable and realizes time synchronization between base stations in a wired manner. The label control module transmits a control signal for the server to the labels through data channels for wireless data transmission. The base stations acquire label positioning information wirelessly and transmit the positioning information back to the server in the wired manner. The server performs label position calculation and presentation, system self-checking and equipment management, time synchronization control, alarm signal control and vehicle control. The automatic proximity perception system realizes quick position detection between vehicles and personnel and realizes simultaneous alarm at the vehicle end and the personnel end. Furthermore the automatic proximity perception system can realize quick vehicle stopping.

Description

technical field [0001] The invention relates to a safety protection system, in particular to an automatic sensing system for personnel approaching of mine underground motor vehicles. Background technique [0002] Some large vehicles in coal mines, due to the position of the driver in the vehicle, determine that their vision is very poor, they cannot make effective observations, and they are easy to squeeze the surrounding staff; on the other hand, due to the working environment The noise / sight is not good, and the staff cannot effectively detect the arrival of the vehicle, and quickly avoid it. [0003] In the existing technology, regardless of the use of RFID technology or radar technology, the working distance (not less than 100 meters) and two-way alarm cannot meet the needs, and it is easy to form dead angles of the antenna, resulting in missed readings. In the coal mine working face, due to the limitation of the working environment, environmental factors such as noise ...

Problems solved by technology

[0002] Some large vehicles in coal mines, due to the position of the driver in the vehicle, determine that their vision is very poor, they cannot make effective observations, and they are easy to squeeze the surrounding staff; on the other hand, due to the working environment The noise / sight is not good, and the staff can't effectively detect the arrival of the vehicle, so they can avoid it quickly

[0003] In the existing technology, regardless of the use of RFID technology or radar technology, the working distance (not less than 100 meters) and the two-way alarm cannot meet the needs, and it is easy to form a dead angle of the antenna, resulting in the phenomenon of missed reading

In the coal mine working face, due to the limitation of the working environment, environmental factors such as noise interference and poor line of sight also greatly affect the application of other technologies

At present, there is no better system to solve this problem
