Personnel monitoring system for transport inclined shaft

Abstract

The invention discloses a personnel monitoring system for a transport inclined shaft, which comprises a system main control box, wherein the system main control box is connected with an optically controlled sensor, a door in-place sensor and a vision sensor, and analyzes and processes data acquired by the optically controlled sensor, the door in-place sensor and the vision sensor; and the system main control box is connected with and controls an explosion-proof electromagnetic lock, realizes the interlocking of driving vehicle and pedestrians in the transport inclined shaft, and ensures that people and vehicles cannot synchronously walk. The system main control box is connected with and controls a monitor, an alarm voice box and a console, the vision sensor comprises a vision server, and the vision server is connected with an explosion-proof camera, and uploads data acquired by the explosion-proof camera to a host computer which is connected with a network switch and is arranged in a ground dispatch room. The system achieves the aims of monitoring the pedestrians in the transport inclined shaft by a winch driver and monitoring personnel of the dispatch room and realizing the automatic control by analyzing and processing signals acquired by the sensors, realizes closed inclined shaft transportation, and ensures that no people walk when the vehicles are driven and no vehicle is driven when people walk.

Description

technical field [0001] The invention relates to a monitoring system of transportation equipment, in particular to a monitoring system applied to personnel in a coal mine transportation inclined shaft, and belongs to the technical field of coal mine inclined shaft transportation monitoring. Background technique [0002] At present, many mines in China use inclined shafts for transportation. Due to the limitation of production conditions, many mines do not have special passages for transporting workers. Instead, they use mixed transportation methods, which are used for both material transportation and pedestrians. [0003] First of all, according to the regulations of "no pedestrians, no pedestrians, no vehicles" in the inclined shaft, it is required that people and vehicles cannot walk together when transporting in the inclined shaft. However, regarding the current situation of inclined shaft transportation in China, there are generally the following problems, that is, before...

AI Technical Summary

Problems solved by technology

However, regarding the current situation of inclined shaft transportation in China, there are generally the following problems, that is, before transporting materials in the inclined shaft, the workers can only confirm whether there are still pedestrians in the inclined shaft by calling the signal workers on the upper and lower slopes of the inclined shaft. There are more than a dozen or even dozens of workers who pass through the transport inclined shaft to the next working face in one shift, but there is no special equipment or staff at the exits and entrances of the transport inclined shaft to register and register the workers entering and exiting the inclined shaft. Inventory and management, and there are many transportation inclined shafts that do not only have two exits, but also one or two exits in the middle of the inclined shaft. This will inevitably lead to the situation that it is impossible to accurately determine whether there are still pedestrians in the inclined shaft. Therefore, just Unable to effectively guarantee "no driving, no pedestrians"

[0004] Secondly, when the inclined shaft is carrying out material transportation, about three mine carts are usually attached to each lifting. The materials to be transported are usually gangue, wood, iron, etc., and the normal lifting speed is 3 meters per second. Here At high speeds, the mine car will vibrate strongly at the joint of the rails, and the materials on the car will easily slip due to the violent vibration. What is more unfortunate is that the mine car will derail due to factors such as the speed of the mine car. The mine car overturns and the car The materials inside will rush down the inclined shaft with strong kinetic energy, causing serious harm. Therefore, it is strictly necessary to ensure that people and vehicles cannot walk together.

[0005] Thirdly, the environment of the transportation inclined shaft is usually relatively harsh, such as smog, humidity, running water on the road surface, smooth, muddy road surface, and dim light. The length of the transportation inclined shaft is usually more than 500 meters, and some are more than 1,000 meters long. Due to the different nature of work, some workers often walk alone in the transportation inclined shaft. If an accident occurs accidentally, it will be difficult to be discovered in time. If driving at this time, it will easily cause personnel safety accidents

[0006] In addition, almost none of the inclined shafts in China has closed the upper and lower wellheads, but only installed a car stopper at each exit and entrance, which cannot effectively prevent pedestrians from entering and leaving the inclined shaft. It is also easy for workers to enter the inclined shaft, thus creating a safety hazard
