Abstract

The utility model discloses a mine safety monitoring system which comprises image devices and a sensor group which are arranged on underground work surfaces. The image device is sued for real-timely monitoring the condition of the work surfaces. The sensor unit is used for collecting conditions of underground fuel gas, carbon monoxide, gas pressure and voltage. The image devices and the sensor group are connected with an aboveground central machine room through communication cables, process acquired video signals, fuel gas, pressure and voltage signals and real-timely transmit the data to a government remote monitoring center through optical fibers. The government remote monitoring center and the data real-time transmission among mines are adopted by the utility model. The government remote monitoring center can real-timely monitor the underground operation conditions of every well, effectively avoid the appearance of phenomena of lawbreaking mining falsification and management confusion, greatly lower the possibility of safe accidents and bring good social benefits.

Description

The mine safety monitoring system

Technical field

The utility model relates to monitoring system, specifically a kind of mine-used monitoring system that integrates video monitoring, network communication, telephone communication.

Background technology

In China's underground work, substantially for a long time be in the state that shuts off oneself from society, for down hole problem and environment, can't monitor in real time, even meet accident, also be difficult to describe or describe unclear during the down-hole people are flurried, the science of delaying is sued and laboured the time, has often caused huge personnel and economic loss.According to incompletely statistics, China only colliery has 2.5 ten thousand approximately, the conservative mine disaster data of official show: dead 6434 people of mine disaster in 2003, dead 6027 people in 2004, dead 5986 people in 2005, the mine disaster number accounts for global 80%, on December 5th, 2007, only the mine disaster in Hongdong, Shanxi is just dead 105 miners, whole nation shock, the group leader of investigation group of State Council, the national chief Li Yizhong of Administration of Work Safety Supervision clapping desk says " what six demonstrate,prove complete? I see it is to be guilty of all the "five evils".", but local government's supervision is ineffective, ore deposit master violation operation is the basic reason that mine disaster takes place.Yet abroad, be example with the U.S.: the safety monitoring system reliability service, aboveground monitor staff can monitor downhole conditions in real time, the underground work personnel again seldom, under control and command, operation is standard very, in case have an accident, be easy to withdraw, injures and deaths are little.Country decision in recent years for this reason: at first step up to close, ban and integrate little colliery; Secondly research and develop coal mine safety monitoring system as early as possible, to satisfy the urgent need of national security and development.

The utility model content

Technical problem to be solved in the utility model provides a kind of mine safety monitoring system, this monitoring system integrates video monitoring, network communication, telephone communication, implement on-line monitoring underground work situation, in time understand the work and the ambient conditions of work plane under the various mines, link up in time and handle, reduce the generation of security incident hidden danger.

For reaching the technical scheme that this purpose takes be:

A kind of mine safety monitoring system, comprise camera head and sensor groups that each scope of operation of down-hole is provided with, camera head in order to miner's number, the excavation mode of real-time each scope of operation of monitoring, have or not and be equipped with self-rescuer and emergency case, sensor groups is in order to the gas under the production wells, carbon monoxide, air pressure and voltage condition; Camera head is connected with the ground central machine room by communication cable for mine with sensor groups, the vision signal and gas, carbon monoxide, air pressure, the voltage signal that collect are handled, vision signal shows on display unit, and with view data by the optical fiber real-time Transmission to government's remote monitoring center, in time handling when unusual appears in gas, carbon monoxide, air pressure, voltage signal, and normal process data and abnormal conditions deal with data are all stored and waited to look into.

In order to adapt to the complex environment under the ore deposit, camera head adopts flame-proof mine optical fiber video camera, and flame-proof mine optical fiber video camera is all steel structure, and good seal performance, and anticorrosion, dustproof, waterproof can set zoom lens.

In order to make video data reduction good, be provided with fiber optic in the central machine room and optical signal is reduced to vision signal and carries out video and supervise through inserting the central machine room server behind the video distributor.

In order to adapt to the adverse circumstances under the ore deposit, communication cable for mine comprises that order wire is to, video cable core, computer cable core and outer field fire retardant jacket.

In order to reach better communication efficiency, order wire is to being provided with polyester belting layer, copper wire woven shield, PE inner liner and wire armoring layer successively between, video cable core, computer cable core and the fire retardant jacket.

The beneficial effect that the utility model can reach is:

1, the utility model adopts the data in real time transmission between government's remote monitoring center and each ore deposit, government's remote monitoring center can implement to monitor the job status of each mine down-hole, avoided ore deposit master's violation to exploit effectively, practised fraud, the phenomenon of managerial confusion occurs, and greatly reduces the possibility that security incident takes place.

2, the utility model adopts flame-proof mine optical fiber video camera, and good seal performance, and anticorrosion, dustproof, waterproof can set zoom lens, long service life.

3, novel cable of the present utility model cooperates with monitoring system, will forecast with unerring accuracy, predicts and handle accident, and the hidden danger that alleviates or reduce security incident takes place, and when reducing production costs, will produce the good social benefit.
