Description
Technical field
The utility model is mining personnel in the pit's framing signal receiving system relates to the signal receiving device that uses in a kind of downhole positioning system, belongs to mining safe early warning apparatus field.Be particularly related to the signal receiving device explosion-proof, accurate positioning function that has that uses in a kind of downhole positioning system.
Background technology
Owing to circumstance complication under the mine, the electromagnetic wave that the signal receiving device that navigation system is used under the mine produces is subject to surrounding environment influence at present, causes existing signal receiving device to receive jitter, locatees inaccuracy.When the down-hole has an accident, be not easy accurately to confirm personnel positions, pointedly trapped personnel is succoured.
Summary of the invention
In order to improve above-mentioned situation; The utility model is mining, and personnel in the pit's framing signal receiving system provides the signal receiving device of the tool explosion prevention function that uses in a kind of downhole positioning system; Cooperate sender unit to use, can effectively improve the stability and the accuracy of signal receiving device reception signal in the early warning system.
The utility model is mining, and personnel in the pit's framing signal receiving system is achieved in that the mining personnel in the pit's framing signal of the utility model receiving system is made up of transducer and charger two parts.Transducer is made up of converter shell, flatter, antenna, oscillating capacitance, oscillator coil, induction coil, gim peg, diode, filter capacitor, A/D converter, controller, output line and lead.Converter shell is the square box of sealing metal material, and square box simultaneously has flatter.Antenna places the flatter bottom.Oscillating capacitance and oscillator coil are connected with antenna through lead after through the lead parallel connection again.Gim peg is with oscillator coil and induction coil is parallel to each other and closely fixing, and induction coil is with to pass through lead again after diode is connected through lead parallelly connected with filter capacitor.The filter capacitor two ends connect the A/D converter through lead.The A/D converter passes through wire connection controller.Controller outer signal output line.Charger is made up of charger shell, transformer and plug.Transformer places in the charger shell, and plug is connected on the transformer.Transformer in the charger connects the intermediate point of A/D converter, controller and oscillating capacitance oscillator coil in the transducer through lead.
During use, under mine, whenever place a signal receiving device at a distance from 10～100 meters fixed position.Every personnel of going into the well carry a sender unit.Oscillating capacitance in the signal receiving device and oscillator coil parallel connection constitute oscillation circuit.After personnel go into the well individual's sender unit is put into the signal receiving device flatter.Sender unit is launched the wireless signal that has personnel's personal information, the antenna receiving signal of signal receiving device with the resonance frequency of oscillation circuit.The signal amplification of in oscillation circuit, vibrating, the electric field that changes.The electric field that changes is in magnetic field that the oscillator coil surrounding space changes.Since oscillator coil with induction coil is parallel to each other and near, so the magnetic field that changes in the space again in the inductive sensor coil generation corresponding electric field.Signal carries out detection through diode again then.The filter away high frequency noise at the filter capacitor place.Import the A/D converter at last, send into controller after being converted into digital signal to analog signal.Controller combines coding after output line is seen off with personnel's personal information and signal receiving device location information, supplies the follow-up equipment monitoring, to confirm personnel's particular location, reaches the purpose of succouring trapped personnel targetedly after mine disaster takes place.
Beneficial effect
One, simple in structure, convenient and practical.
Two, with low cost, be convenient to promote.
Three, tool explosion prevention function, signal stabilization, location are accurately.
