Owing to be subjected to the influence of subsurface environment, signals such as wireless and infrared rays can't be grown Distance Transmission, the framing signal that the entrained individual signal processor of underground work personnel is launched needs to transfer to aboveground control room with a plurality of transferring equipment relays, with definite underground work personnel's position, and these transferring equipment need aboveground power supply power supply.After accident takes place, occur that supply line interrupts, transferring equipment is damaged or situation such as buried through regular meeting, therefore can only be as the down-hole positioning means under the normal condition, and also its positioning result exists uncertain; In addition, for the measurement of downhole temperature, humidity, gas density, each mining area all is to adopt the special messenger regularly to patrol and examine, and wastes time and energy, and can't avoid personnel's irresponsible behavior.
Summary of the invention
The present invention can't operate as normal after the down-hole has an accident in order to solve existing underground monitoring and positioner, and exists the location inaccurate, and the problem that monitoring is wasted time and energy provides a kind of underground monitoring and positioner.And be purpose only with the hardware configuration that this device is provided.
The present invention adopts following technical scheme to realize: a kind of underground monitoring and positioner, by individual signal processor, signal transmission component, the signal processing apparatus of aboveground signal processor and Computerized analysis system formation and the well head receiving record device that links to each other with computer constitute, between individual's signal processor and the signal transmission component is transmission of wireless signals, signal transmission component is to link to each other with aboveground signal processor in the signal processing apparatus, that be provided with along underworkings and with signal processing apparatus in the armouring radio-frequency cable of impedance matchings such as aboveground signal processor, the metal screen layer of armouring radio-frequency cable has hole every a segment distance.
On the individual signal processor of the present invention sensor is installed.For example: temperature pick up, humidity sensor, gas concentration sensor etc., the various physics and chemistry amount signals of monitoring that need in the detected down-hole of sensor are through individual signal processor internal circuit modulation and emission, signal transfers to aboveground signal processor and imports computer by the impedance radio-frequency cables such as armouring that the down-hole has hole, when realizing personnel positioning, also realized real-time monitoring to the subsurface environment situation.
Essence of the present invention is to have adopted the armouring radio-frequency cable that has hole on it as signal transmission component, thereby changed the signal transmission manner, the reliability degree affected by environment of signal transmission is reduced greatly, transmit existing problem thereby overcome existing underground signal.
Based on the hardware configuration of device of the present invention, multiple signal transfer mode can be arranged.Individual's signal processor can be the signal projector that only transmits, and its emission is with the radio-frequency (RF) pulse signal and the modulated sensor signal of the modulation of Personal Numbering signal; Correspondingly the aboveground signal processor in the signal processing apparatus can be the signal receiver that receives only signal; The hole of signal (the Personal Numbering signal and the sensor signal that comprise modulation) on the armouring radio-frequency cable of individual's signal projector emission enters the armouring radio-frequency cable, and flowing to aboveground signal receiver (receive frequency of aboveground signal receiver is consistent with the tranmitting frequency of individual signal projector), aboveground signal receiver carries out sending into computer again after the demodulation to signal.Individual's signal projector is the transmit clock pulse signal at any time, the miner who carries individual signal projector is when well head enters, well head receiving record device is noted miner's (individual signal projector) through moment of well head and be transferred to computer in the signal processing apparatus, the zero-time that positions, monitors as computer; Receive under the known prerequisite of the moment (this moment writes down when receiving signal by computer), the signaling rate of this pulse signal at the interpulse period of pulse signal that individual signal projector is sent out, aboveground signal receiver, computer is under the support of corresponding software, can calculate the length of signal launch point, promptly realize the location apart from well head.At this moment, the reflection of the signal of the respective sensor that receives of aboveground signal receiver is the environmental aspect of miner position this moment.Under this kind signal transfer mode, be can be by (the regulating button as being provided with on individual signal projector) of carrier oneself adjusting the interpulse period of the radio-frequency pulse of individual's signal projector emission, under the normal condition, interpulse period can be longer relatively, occurring under the emergency of accident, the carrier connects down the adjusting button and comes chopped pulse blanking time, with satisfy under the emergency at any time, fast the location, follow the tracks of.If but individual signal projector carrier is injured or can't press when regulating button because of other reason in accident, because of aboveground operating personnel uncontrollable interpulse period, can influence under the emergency at any time, follow the tracks of the location fast.
Individual's signal processor also can be the signal transceiver, and correspondingly the aboveground signal processor in the signal processing apparatus also is the signal transceiver.Under the control of computer, aboveground signal transceiver emission and the corresponding start pulse signal of individual signal transceiver in the signal processing apparatus, this start pulse signal is launched along transmission of armouring radio-frequency cable and hole from it, after individual's signal transceiver receives this start pulse signal, emission is with the location radio-frequency (RF) pulse signal and the modulated sensor signal of the modulation of Personal Numbering signal at once, and be transferred to aboveground signal transceiver in the signal processing apparatus through the armouring radio-frequency cable, send into computer after the demodulation again.The x time of start pulse signal and receive moment of feedback signal under the computer recording, under the known situation of signaling rate, computer can calculate the length of signal launch point apart from well head under the support of corresponding software, promptly realize the location.Whether the effect of well head receiving record device is to gather the personal characteristics code signal corresponding with individual signal transceiver and send into computer, go into the well and whether go up well again to show specific individual signal transceiver; Computer is only under the situation that receives this personal characteristics code signal, just can launch the start pulse signal corresponding (process well head during the last well of miner with this individual's signal transceiver, computer receives the personal characteristics code signal once more, to stop to launch and the corresponding start pulse signal of this individual's signal transceiver), like this, more and when not going into the well simultaneously in individual signal transceiver quantity, can avoid aboveground signal transceiver to launch the start pulse signal of the individual signal transceiver of not going into the well meaninglessly.Certainly,, also can not adopt well head receiving record device under this kind signal transfer mode and under the situation of individual signal transceiver negligible amounts, this be those skilled in the art on the technical solution of the present invention basis, the easiest constructional variant of associating.For confirming whether individual signal transceiver goes into the well, and individual signal transceiver can be launched the personal characteristics code signal continuously, during miner's process well head, well head receiving record device receives this signal and delivers to computer; Well head receiving record device also can be launched the start pulse signal that is used to search for individual signal transceiver continuously under computer control, during miner's process well head, its individual signal transceiver that carries receives this start pulse signal, launch the personal characteristics code signal, well head receiving record device receives this personal characteristics code signal and sends into computer at once; Even well head receiving record device can adopt the magnetic card attendance recorder, and the magnetic card attendance recorder was sent signal into computer after the miner swiped the card, and equally also can reach the purpose of confirming whether individual signal transceiver goes into the well.Adopt this trigger-type signal transfer mode, the location of individual's signal transceiver and the emission of sensor signal are that the start pulse signal that sent by aboveground signal transceiver is controlled, it is advantageous that aboveground operating personnel can be provided with or regulate the blanking time of start pulse signal at any time, normal condition following blanking time can be longer, can be shorter when urgent, be convenient to aboveground operating personnel's operation control.
No matter individual's signal processor and aboveground signal processor are to use as transmitting and receiving device, still use as transceiver, it realizes the those of ordinary skill of the internal circuit configuration of above-mentioned functions to electricity or signal and communication field, all be known and very easy realization, and the modification of multiple different structure can easily be arranged; Well head receiving record device also is like this.Therefore, the present invention is not described specifically their internal circuit configuration.
The present invention has adopted the armouring radio-frequency cable as the underground signal transmission part, itself is a passive device, does not have powerup issue, and not installing and using in the down-hole to have any influence to safety in production, can extend to each workspace with the driving progress; And armouring radio-frequency cable tension, compressive strength height, (as water logging or big fire) damages the armouring skin even the down-hole has an accident, as long as heart yearn is continuous, and still can the normal transmission signal.Can well realize the signal transmission of down-hole, for the reliable location of realizing the underground work personnel provides necessary condition; In addition, the present invention is sensor installation on individual signal processor, and the ambient conditions at each position under the monitor well need not to send the special messenger regularly to patrol and examine in real time.
