Abstract
The present invention is a kind of Intellective Communication System that underground coal mine uses.Base station and base station, base station and terminal room are wireless link, using dynamic can automatic compensation Time synchronization technique, and can time delay command coding and tree network Intelligent routing technology, the flexible wireless telecommunication system of base station Dynamical Deployment is realized with relatively low cost, it is easy to the routine safety management and scheduling of the complex environments such as colliery, and base station is in itself from charged pool, it can also be used to accident rescue and the scene of the accident well ground emergency communication.
Description
Technical field
The system belongs to wireless communication technique field, while is communicated using radio frequency time-division and frequency division technique, time synchronized skill
Art, narrowband speech compression coding and decoding, radio-location technology etc..
Background technology
Due to typical wireless digital communication system such as Personal Handyphone System, GSM and CDMA etc. be all based on accurate time synchronized and
High-speed data exchanges (as interconnected using optical fiber or twisted-pair feeder) between base station, is not suitable for very much the rescue communication of emergency arrangement,
It is not suitable for use in the environment of the inferior dynamic change of coal mine, the system uses wireless link completely, can be automatic using dynamic
The Time synchronization technique of correction, and can time delay command coding and tree network Intelligent routing technology, realized with relatively low cost
The flexible wireless telecommunication system of base station Dynamical Deployment, can be not only used for routine safety management and the tune of the complex environments such as colliery
Degree, it can also be used to accident rescue and the scene of the accident well ground emergency communication.,
The content of the invention
The present invention is that a kind of collection ground and the communication of under-well bi-directional real-time voice, Word information communication, personnel positioning, gas pass
The pocket underground working communication instrument that sensor numerical value long distance wireless is collected and four big function of early warning is integrated.System is using wirelessly
Electric positioning principle, reach the two-way real-time communication between ground control centre and underground operators.It is wireless between all devices
Connection.
Embodiment
Present system embodiment is used for management of the underground coal mine administrative staff for coal miner, safety manager
Monitoring to working environment, the report for the emergency risks situation that happens suddenly, timely communication during emergency relief.
Real-time gas density is shown on the display of A ore deposits ground control centre, according to these data, safety manager
Mr. Zhang understands the slight change of operating environment under ore deposit and makes corresponding instruction in time.Also it will appreciate that the work to underground handheld terminal
Make the accurate location residing at present such as personnel 165,166.Same day underground administrative staff 165,166 issue " normal " by terminal and referred to
Order, ground control centre receives normal information.Mr.'s A press-to-talk key, selection and No. 165 terminating machine carrier are conversed,
Mr. Zhang broadcasts a highlight on the same day to the whole network immediately after end of conversation.All information are all completed by wireless network,
And placed on record by control centralized computer.All gas that upper management personnel can transfer specified day from computer at any time pass
Sensor sensed data and message registration, it is clear and definite so as to responsibility.
There is red gas exceeding limit alarm on some time one day, the display of ground control centre in B ore deposits, and picture shows the 20th
Number base station finds gas exception automatic alarm, and Mr. Zhang presses " Evacuation " button, now, the end just in underground work immediately
Evacuation indicator lamp lights on end, and underground LED billboard, which is shown, withdraws the information such as direction, arrow.Guide worker rapid orderly
Withdraw, avoid the generation of major accident, improve life and property safety guarantee.
Mine cave in accident occurs for C ore deposits, is fitted without this intelligence system before, several miners do not withdraw in time, and situation is tight
It is anxious.Rescue team carries some base stations and terminal, the very first time rush to the scene of the accident, because the system is wireless connection, and base station
And terminal can voluntarily work more than 72 hours from charged pool in the case of without external power supply.Complete communication network is with rescue
The propulsion of team member and quickly extend.The Real-time Monitoring Data of the site of an accident is transmitted on the display of movements control center, underground is rescued
Help personnel and carry out voice call at any time with ground control personnel, so that ground control personnel grasp downhole rescuing progress and hair at any time
Cloth instructs.Farthest reduce casualties and property loss.
Claims (6)
