Mine disaster early warning and rescue system, as depicted in figs. 1 and 2, comprise shell 9, shell 9 is installed air channel 12, shell 9 is stretched out at two ends, air channel 12, one end provided with fan 10 in air channel 12, the outside portion of shell 9 arranges RDIF read write line 6, in shell 9, sensor is set, A/D converter 2, single-chip microcomputer 5, Wireless transceiver module 7, sensor is by firedamp sensor 1, humidity sensor 3 and temperature pick up 4 form, the inductive probe of sensor stretches in air channel 12, sensor is all connected single-chip microcomputer 5 with RDIF read write line 6, wherein firedamp sensor 1 connects single-chip microcomputer 5 by A/D converter 2, single-chip microcomputer 5 connects wireless transport module 7, wireless transport module 7 wireless connections warning device 8.Fan 10 can drive air air channel 12 process later, and the inductive probe of sensor can measure performance in mine.Link 11 is installed on described shell 9 top, conveniently hangs up at mine.The utility model can be multiple, is arranged on the diverse location of mine respectively.
The principle that native system is followed " unified payment tag card, unified equipment, unified management ", carry out " people one tag card " system by personnel on duty and teams and groups, this tag card can be considered " voucher on duty " or " tunnel admission card ".This tag card is RF tag, can be arranged in the work board of employee.Concrete scheme is as follows.
The utility model of some is all installed in all tunnels by shaft production unit, and particular location according to the situation, is as the criterion to meet radiation areas.
Shaft production unit provides tag card to personnel in the pit, and tag card carries by personnel in the pit is next to the skin.When sending out tag card tag card said the essential information of corresponding employee, comprise name, age, sex, affiliated teams and groups, affiliated work post, post etc. and log in system database.
Namely safety in production department comes into force after authorizing this tag card.The scope of authority comprises: this employee qualifiedly can enter the tunnel of the scope of operation, the timeliness of tag card, loses efficacy, reports the loss, and enters tunnel to prevent unrelated person and unauthorized person.
The personnel entering tunnel must wear tag card.But this person is through the identification monitoring point in tunnel, immediately by system identification, and by the information exchange of grid, the information transmission such as section this person passed through, time are to aboveground safety monitoring center record.If the mark card number of induction is invalid or enter limiting channel, system is by automatic alarm, and safety monitoring center operator on duty receives the report for police service signal, performs associated safety work management program immediately.
Once there is security incident in tunnel, safety monitoring center can know the basic condition (which place when certain employee pass through) of trapped personnel in the very first time, search-and-rescue work can be shot the arrow at the target, wrecker uses mobile far-distance from recognition device, the position of convenient detection distress personnel in certain scope, is convenient to the safety and efficiently running of rescue.
The design of downhole data acquisition module
The part of data acquisition of this part mainly early warning, image data mainly uses three sensing systems: temperature pick up, humidity sensor and firedamp sensor, the data that sensor detects convert data signal to through A/D converter TLC549 analog signal, through single-chip microcomputer 89C52 process, through wireless network terminal transmission earthward, down-hole information Data Comparison when normally producing in the information collected and database, thus can learn whether there is potential safety hazard.
Wireless transport module selects NRF24L01, and it is Monolithic RF transceiver, and operating voltage is 3.3 ~ 3.6V, works in 433/868/915MHz tri-channels.NRF24L01 is made up of frequency synthesizer, receiving demodulation device, crystal oscillator, power amplifier and modulator, automatic process prefix and carry out CRC (CRC), SPI interface and single chip communication can be used, peripheral circuit is simple especially, conveniently can be connected with single-chip microcomputer, configure also very convenient.NRF24L01 is applicable to the numerous areas such as radio alarming, wireless data monitoring.Be applicable to the frequency of 400MHZ based on Mine Radio Transmission, therefore NRF24L01 can meet the functional requirement of this design, and therefore this design selects NRF24L01 chip as wireless transmitting-receiving equipments.
