Abstract
The invention relates to an intelligent communication system used underground for a coal mine. Base stations are mutually linked in a wireless manner, the base stations and terminals are also linked in the wireless manner, and the dynamic time synchronization technology capable of carrying out automatic compensation and the delayable command code and tree network intelligent routing technology are used, thereby realizing the flexible wireless communication system of dynamic deployment of the base stations with low cost, and facilitating the daily safety management and the scheduling of the coal mines and other complex environments; furthermore, the base stations have batteries, so that the intelligent communication system can also be used for accident rescue and accident scene well surface emergency communication.
Description
Technical field
Native system belongs to the wireless communication technique field, uses radio frequency time-division and frequency division technique communication simultaneously, Time synchronization technique, narrowband speech compression coding and decoding, radio position finding radio directional bearing technology etc.
Background technology
Because typical wireless digital communication system such as Personal Handyphone System, GSM and CDMA etc. are based on precise time synchronously and high-speed data exchange between the base station (as using optical fiber or twisted-pair feeder interconnected), be not suitable for very much the rescue communication of emergency arrangement, be not suitable in the environment of the inferior dynamic change of coal mine yet, native system adopts wireless link fully, use dynamically the Time synchronization technique of revisal automatically, but and time-delay command coding and tree network intelligence route technology, realized the wireless telecommunication system flexibly that the base station is dynamically disposed with lower cost, both can be used for the routine safety management and the scheduling of complex environments such as colliery, also can be used for accident rescue and well ground, scene of the accident emergency communication.
Summary of the invention
Be a kind of ground and the communication of under-well bi-directional real-time voice, Word information communication, personnel positioning, firedamp sensor numerical value long distance wireless is collected and early warning four big functions are one pocket underground working communication instrument of collecting.System utilizes the radio position finding radio directional bearing principle, reaches the two-way real-time communication between ground control centre and underground operators.Be wireless connections between all devices.
Embodiment
System implementation mode of the present invention is used under the coal mine administrative staff for the management of coal miner, and the safety manager is to the monitoring of operational environment, the report of burst emergency risks situation, the timely communication during emergency relief.
Show real-time gas density on the display of ground control centre, A ore deposit, according to these data, safety manager Mr. Zhang in time understands the slight change of operating environment under the ore deposit and makes corresponding indication.Also can recognize the present residing accurate positions such as staff 165,166 of down-hole handheld terminal.The same day, down-hole administrative staff 165,166 were by terminal issue " normally " instruction, and normal information is received in the ground control centre.Mr.'s A press-to-talk key is selected and No. 165 terminating machine carrier converse, and Mr. Zhang is immediately to the whole network broadcasting highlight on the same day behind the end of conversation.All information are all finished by wireless network, and the Be Controlled centralized computer is placed on record.The upper management personnel can transfer all firedamp sensor sensed data and message registrations of appointed date at any time from computer, so that responsibility is clear and definite.
The B ore deposit is in some time one day, red gas exceeding limit alarm appears on the display of ground control centre, picture shows the unusual automatic warning of No. 20 base station discovery gas, Mr. Zhang presses " promptly withdrawing " button immediately, at this moment, just promptly withdrawing indicator light and light on the terminal of underground work, down-hole LED billboard shows the information such as direction, arrow of withdrawing.The generation of major accident has been avoided in guiding workman orderly withdrawing rapidly, has improved life and property safety guarantee.
Mine landslide accident takes place in the C ore deposit, and this intelligence system is not installed before, and several miners in time do not withdraw, and the situation is critical.Several base stations and terminal are carried by rescue team, and the very first time is arrived in the scene of the accident, and because of native system is wireless connections, and base station and terminal can be worked more than 72 hours under no external power supply situation voluntarily from charged pool.Complete communication network extends fast along with rescue team member's propelling.Transmit the real-time Monitoring Data of the site of an accident on the display of movements control center, downhole rescuing personnel and ground control personnel carry out voice call at any time, so that the ground control personnel grasp downhole rescuing progress and issuing command at any time.Farthest reduce casualties and property loss.
Claims (6)
1. an intelligent wireless communication system for coal mine is characterized in that, need not to use traditional twisted-pair feeder or optical fiber to connect between the base station, also uses wireless telecommunications to carry out route and communication between the base station.
2. wireless telecommunication system as claimed in claim 1, each base station is used and is made up of 2 radio transceiver unit and 2 smart antennas, carry out time-sharing receive and transmit(tsrt) and exchanges data synchronously by strict time between 2 unit, wherein wireless data exchange is carried out in 1 Transmit-Receive Unit and network uplink base station, and wireless data exchange is carried out in the descending base station of another Transmit-Receive Unit and network.
3. wireless telecommunication system as claimed in claim 2, base station, down-hole and ground base station are formed communication network jointly, can transmit real-time voice, (gas, temperature etc.) sensing data, and possess the terminal positioning function.
4. wireless telecommunication system as claimed in claim 3, system can form the strand network, also can form tree-like crossover network.
5. wireless telecommunication system according to claim 1, ground can send " promptly unconditionally withdrawing " instruction to all terminals of down-hole by a button.
6. as wireless telecommunication system as described in the claim 5, the down-hole terminal can by button earthward control centre send " emergency ", " gas is unusual ", " permeable ", " normally ", information commands such as " in place ".
