Abstract
The utility model discloses a portable person seeking instrument which is used for detecting the position of the buried and blocked person in the industrial and mining wells or other tunneling engineering. The utility model adopts the passive sticker detecting principle, the utility model is composed of a transmitter and a receiver, wherein, the transmitter is carried by the rescued person, and the receiver is carried by the rescue worker. The electromagnetic signal transmitted by the transmitter is received by the receiver within 30m, the electromagnetic signal is converted to the audio signal or the electrical signal, and thereby, the position of the rescued person who carries the transmitter can be displayed.
Description
The utility model relates to a kind of Calling person instrument, especially a kind of portable Calling person instrument that is buried the personnel positions that is blocked of surveying.
Accidents such as roof fall, sheet nation easily take place in colliery, metallurgical ore deposit, nonferrous metals ore, the tunnel mining operation, the field personnel is easily emitted junk or is caved in to bury and block, and this determines the position of being buried the personnel of being blocked rapidly and exactly so that give first aid to timely with regard to needs.Determine the method for being buried the personnel positions that is blocked for exploring in the short time, people have done the effort of decades.The 23 the international mining safety proceeding (U.S., in September, 1989, the 73-76 page or leaf) paper in " underground work personnel's monitoring systems " has been reported Japanese colliery for determining underground work personnel residing position when disaster takes place, set up underground work personnel's monitoring system, this device is made up of individual transmitter, antenna, frequency changer, down-hole fixed station and ground monitoring station.Individual's transmitter is contained in the lampshade of safety cap, the emission cognizance code.Code is received by antenna, through the frequency changer conversion frequency, is transported to the ground monitoring station after fixed station arrangement, and all data are in the monitoring station integrated treatment, and shows on screen, obtains the information of underground work personnel positions thus.This system works dependable performance, but mechanism is huge, and device is complicated.
The purpose of this utility model provides a kind of portable Calling person instrument, and it is simple in structure, and volume is little, in light weight, can detect the position of being buried the personnel of being blocked in the 30m scope.
Key points in design of the present utility model is, Calling person instrument adopts the passive detection principle design of replying, with solution be in by dilapidation bury, the human body reflecting properties is poor under the stifled situation, electromagnetic signal is broadcast and is passed the characteristic challenge, Calling person instrument only is made up of transmitter and receiver two parts, transmitter is by being worn by the rescue personnel, receiver is worn by the rescue personnel, the electromagnetic signal that transmitter is launched changes the audio signal or the signal of telecommunication into and is shown to the rescue personnel after being received by receiver, reaches the accurate judgement of rescue personnel with this and wears the purpose that this transmitter personnel are buried, block up the position.Transmitter is the minicomputer of an essential safe type, do not establish hand switch, can be used as power, can be used as power yet by external power source by self-contained battery, preferable is to be used as power or to be combined as a whole with mine lamp by the mains lighting supply of being worn by the rescue personnel, continuously transmitted pulse formula electromagnetic signal.Disturb for preventing that various media between the Receiver And Transmitter such as ore, mine timber, water etc. from forming this kind electromagnetic signal, cause direction and the last deviation of distance, the wavelength of determining electromagnetic emission is necessary, proves already, select the frequency of ELF section for use, can make Calling person instrument correctly determine the orientation.The weight of transmitter and size should be advisable conveniently to be worn by the rescue personnel, and transmitter preferably can be put into the lighting device or the dressing of being worn by the rescue personnel.Receiver is a kind of essential safe type, the locate mode device of using battery power, it can be a kind of single body, also can be combined by some midget plants, preferable receiver can be worn in the front by the rescue team member, is convenient to them in scene of the accident fast moving.For investigative range is increased, dedicated antenna is set, in the Calling person instrument according to antenna theory and Theory of Electromagnetic Field, desirable scheme is to adopt magnetic antenna emission, magnetic antenna to receive, and can make the electromagnetic signal penetration power of emission strong, and it is little to decay, be easy to be received, reach the purpose that increases investigative range.
Compared with prior art, the utlity model has following advantage: (1) the utility model adopts the passive detection principle design of replying, make Calling person instrument be in the simplest structure, only need be worn transmitter by the rescue personnel, the rescue personnel only need be equipped with receiver, do not need other auxiliary equipment, and transmitter and receiver is very light, increase added burden in the time of working can for rescue personnel and rescue personnel at the scene, thereby, do not possessing under huge, the complete monitoring system situation, using this instrument to reach and accurately verify the purpose of being buried stifled personnel positions rapidly.(2) electromagnetic signal is buried in well industrial and mineral and various Tunnel Engineering, decay is little in stifled field personnel's this layering lossy dielectric of dilapidation, intensity is high, and magnetic antenna has the characteristics of this electromagnetic signal of selective reception electromagnetic field component sign, compare with the Calling person instrument that adopts electric antenna, the utility model adopts magnetic antenna to transmit and receive machine, be easy to increase the sensitivity of Calling person instrument, and investigative range is increased.(3) transmitter is not established hand switch, launches electromagnetic signal all the time, has guaranteed that disaster has little time suddenly to open the personnel of switch or forget the personnel that open switch temporarily, all can in time be given first aid to.
Its technical characterictic is:
The circuit of transmitter 1 is simple as far as possible effectively, emission speciality ripple, and to improve transmitted wave to stifled penetration capacity of burying medium, its transmitting antenna adopts special high permeability magnetic rings antenna, and this can minification, reduces cost, can improve its radiation efficiency again.
Receiver circuit is by using narrow-band design, the about 20Hz of the bandwidth of complete machine.Can improve the sensitivity of receiver like this, reduce requirement, thereby can reduce the designed power consumption values of transmitter circuitry the transmitter radiant power, prolong transmitter supply service time, doing power supply with general mine lamp is example, generally speaking, can keep 3 day time effectively.
Below in conjunction with drawings and Examples technical characterictic of the present utility model is described further.
