Abstract
The utility model belongs to the technical field of alarm, which discloses a mine alarm positioning device. The utility model is characterized in that the mine alarm positioning device comprises a wireless signal receiving mechanism arranged in a mine tunnel, a monitoring and positioning mechanism which is connected with the wireless signal receiving mechanism via transmission cables and arranged on the ground, and a wireless signal sending mechanism which is fixed on the body of a miner and provided with a gas density sensor. The mine alarm positioning device can accurately detect the gas density of different positions in the mine tunnel, and a supervisor can clearly know the gas density under a mine. Therefore, the mine alarm positioning device can effectively detect and previously alarm mine gas accidents.
Description
Technical field
The utility model belongs to the alarm technique field, relates in particular to a kind of warning positioner that is used for mine laneway.
Background technology
At present, the coal mine gas explosion accident is high, and all cause huge property loss and personal injury every year, traces it to its cause, and mainly is to lack effectively supporting methane Concentration Measurement and early warning means.
The utility model content
The purpose of this utility model just provides the mine warning positioner that a kind of gas density and testing agency match.
The technical solution adopted in the utility model is:
A kind of mine warning positioner comprises:
Be arranged at the wireless signal receiver structure in the mine laneway, be arranged at ground monitoring detent mechanism by what transmission cable was attached thereto; With
Be fixed in miner's wireless signal transmitter structure that has gas concentration sensor on one's body.
Its additional technical feature comprises:
Described wireless signal receiver structure is at least two;
Described wireless signal receiver structure is made of reception antenna, wireless receiver and decoder;
Described wireless signal transmitter structure constitutes by gas alarm, encoder, wireless signal transmitter with the corresponding transmitting antenna of described wireless signal receiver structure reception antenna;
Between described wireless signal receiver structure for being connected in series;
Described radio reception mechanism is with being that ring-type connects between described monitoring detent mechanism.
A kind of mine warning positioner provided by the utility model, compared with prior art have the following advantages: one, because the wireless signal transmitter structure of gas concentration sensor is fixed on one's body the miner of operation in the underworkings, what zone the miner is in will detect this regional gas density, and receive by the wireless signal receiver structure that is arranged in the tunnel, and be transferred to and be arranged at ground monitoring and early warning mechanism, make the monitor staff come into plain view, can effectively prevent the generation of accident the gas density situation of down-hole; Its two owing to constitute the ring-type syndeton when being connected in series between radio reception mechanism and monitor control mechanism, even therefore during the fracture of stube cable one place, native system is appointed and can be sent alarm signal and do not lose its warning function.
Description of drawings
Fig. 1: the structural representation of mine warning positioner;
Fig. 2: the structured flowchart of mine warning positioner wireless signal receiver structure;
Fig. 3: the structured flowchart of mine warning positioner wireless signal transmitter structure.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing a kind of mine warning of the utility model positioner.
Be illustrated in figure 1 as the structural representation of mine warning positioner, promptly comprise the monitoring locator 1 in being arranged between ground handling, be fixed in the mine laneway 2 by comprising reception antenna 3 as shown in Figure 2, the radio receiver 6 that wireless signal receiver 4 and decoder 5 constitute (designs the number of this receiver according to the length in tunnel, it can be 50, also can be 100), pass through between monitoring locator and radio receiver by signal transmssion line, leader cable 7 annulars that power line constitutes connect, also comprise in addition be fixed in the miner on one's body as shown in Figure 3 by gas alarm 8, encoder 9, transmitting set 10 and transmitting antenna 12 that constitute with radio receiver 6 corresponding transmitting sets 11.Transmitting set 11 can be fixed in the mine lamp on the miner crown, also can be fixed in other exposure portion.
Its operating principle is, when the miner enters higher regional of gas density, its gas alarm produces alarm signal, weave into behind the alarm code by wireless signal transmitter and transmission antennas transmit by encoder 9, its reception antenna 3 nearby receives, again after wireless receiver receives the decode the address code that device solves receiver again the signal transmssion line through leader cable 7 reach monitoring locator 1.Because therefore the address code difference that different wireless signal receivers is compiled can receive near the gas situation in this signal wireless receiver address so that the tunnel can be known in ground, in time takes preventive measures.
Since as shown in Figure 1 mine warning positioner 6 of radio receivers be the annular syndeton of series connection, therefore, even when the connection leader cable opens circuit, received signal can be reached monitoring locator 1 too, make its warning function realize in the same old way.
Claims (6)
1, a kind of mine warning positioner is characterized in that comprising:
Be arranged at the wireless signal receiver structure in the mine laneway, be arranged at ground monitoring detent mechanism by what transmission cable was attached thereto; With
