Abstract
The utility model discloses a point-to-point positioning system used for underground tunnels. The point-to-point positioning system used for the underground tunnels comprises a plurality of position indicators, emission instruments installed on movable equipment and a control center arranged on the ground. The position indicators are distributed and fixedly arranged in the underground tunnels, and are connected with the control center in a wired mode. The emission instruments are worn by underground working personnel, and are in wireless point-to-point communication with the position indicators so as to enable the position indicators to obtain the angle and distance information of the emission instruments and the position indicators. The control center receives angle and distance information transmitted by the position indicators and then carries out processing on the information so as to position the emission instruments. According to the point-to-point positioning system used for the underground tunnel, the system structure is simple; the creation cost is low; passing-by positioning precision is provided through point-to-point positioning technology applied between the emission instruments and the position indicators; and heading positions of the underground working personnel can be determined.
Description
Technical field
The utility model belongs to point-to-point positioning and communicating technical field, relates in particular to the location technology in the drive of down-hole.
Background technology
Down-hole drive operation is a breakneck job; safety in order to ensure operating personnel when there is mine disaster; conventionally can build in down-hole operating personnel's DYNAMIC DISTRIBUTION and locating and monitoring system, thereby can the very first time notify personnel to withdraw when there is mine disaster, and underground equipment is dispatched.But current downhole positioning system is complicated, and construction cost is high, and makes communications limited because down-hole is with a varied topography.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this utility model has been to provide the point-to-point positioning system for down-hole drive, this system constructing cost is low, communication location is more reliable.
Technical scheme: for achieving the above object, the utility model is by the following technical solutions: a kind of point-to-point positioning system for down-hole drive, comprising distributes is fixed on a plurality of orientators in the drive of down-hole, be arranged on the transmitter on removable equipment and be located at ground control center, described orientator is fixing to be distributed in vertical hoistway and horizontal tunnel simultaneously, and is connected with ground control center by wire transmission network; Between described transmitter and orientator, adopt wireless points point to-point communication technology to be connected; And described transmitter is provided with for receiving the active module of activation signal.
As preferably, described orientator and transmitter adopt radio frequency identification communicator.
Further improve, the porch in described tunnel is provided with two radio-frequency identification reader/writers successively along roadway direction.Thereby make, when underground operators passes through tunnel, by radio-frequency identification reader/writer, to receive the sequencing of signal, thereby know the direct of travel of underground operators in tunnel.
Described single transmitter communicates to connect with two orientators simultaneously, thereby can locate by triangle, improves the positioning accurate accuracy of transmitter.
Described orientator and transmitter adopt Zigbee communication device, thereby can meet the transmission of big data quantity.
Beneficial effect: compared with prior art, the utlity model has following advantage: this system architecture is simple, create cost low; By the wireless points between transmitter and orientator to point location technology have through positioning precision, can also determine the direct of travel of underground operators simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of point-to-point positioning system described in the utility model;
Fig. 2 is the functional-block diagram of point-to-point positioning system described in the utility model.
Wherein, orientator 1, transmitter 2, control center 3, radio-frequency identification reader/writer 4.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As illustrated in fig. 1 and 2, a kind of point-to-point positioning system for down-hole drive, comprise above ground portion and under ground portion, enough a plurality of orientators wherein distributes in underground vertical hoistway and tunnel, this orientator for receive that transmitter that underground operators carries sends radio coding signal, thereby obtain relative angle and distance between transmitter and orientator, also can be that near a plurality of orientator receives radio coding signal that transmitter sends and carries out triangle location technology and determine the relative position information between transmitter and orientator, and this radio coding signal is sent to the control center of above ground portion by the data transmission network of underground wired mode, control center carries out data processing and analysis, and on display screen, demonstrate operating personnel in the exact position of down-hole, adopt this point-to-point locator meams to determine operating personnel's position.This point-to-point location technology can adopt the Zigbee mechanics of communication RFID REID alive that cost is lower.
For using electricity wisely, transmitter is provided with active module in addition, enters duty after transmitter receives activation signal, and when transmitter does not receive activation signal, transmitter is in dormant state.Further improve, can set gradually in the porch in every tunnel two radio-frequency identification reader/writers, when operating personnel carries transmitter turnover tunnel, by radio-frequency identification reader/writer, receive the sequencing of radio frequency identification signal, thereby can determine the working direction of operating personnel in tunnel.
