Solenoid valve on machine and receiver, the gas concentration information for being also used to detect detector are sent to processing system；
The processing system, for receiving and processing radio wave signal and gas concentration information.
The working principle of base case: when needing to carry out stope perspective detection, start Radio Penetration
Instrument all devices arrange multiple launch points in the tunnel of stope side, in the other side of the stope
The multiple receiving points of roadway layout are received using one of launch point and a receiving point as initial transmissions point and initially
Transmitter is placed on initial transmissions point by point, and receiver is placed on initial receiving point, and transmitter is emitted certain by transmitting antenna
The radio wave signal of frequency, radio wave are propagated in stope, and receiver is received by receiving antenna across back production
Processing system is passed to after radio wave signal after working face, processing system receives and processes radio wave signal.
Wherein, transmitter and receiver is respectively connected with elevating mechanism, and elevating mechanism includes cylinder body and slides with inboard wall of cylinder block
The piston of cooperation, cylinder body are divided into storeroom and sensing chamber by boundary of piston, and the side that piston is located at sensing chamber is connected with stretching cylinder
External connecting rod, one end that connecting rod is stretched out outside cylinder body are connect with the transmitter or receiver, and storeroom, which is communicated with, to be inhaled
Sucker is pressed on the tunnel roof of stope by the sucker being attached on the roof of tunnel using external force, and sucker is tightly attached to lane
After on road roof, the air pressure of suction cup interior is far smaller than ambient pressure, so being connected to sucker under the action of external atmosphere pressure
The elevating mechanism and transmitter or receiver of lower section can be suspended in tunnel together, be equipped with detector since detection is indoor,
The certain space measurement gas concentration of indoor needs is detected, so the setting of limited block avoids piston and continues to move downward, from
And it is supplied to the enough spaces of sensing chamber；
Open simultaneously the solenoid valve on transmitter and receiver using controller, at this time by solenoid valve completely cut off storeroom with
Sucker connection, since the air pressure of suction cup interior is far smaller than ambient pressure, storing indoor air pressure is atmospheric pressure, sucker and storage
There are pressure differences between room, so storing indoor portion gas can be entered in sucker by solenoid valve, store indoor gas
It reduces, air pressure reduces, and extraneous atmosphere will push piston and move up, and the movement of piston will drive connecting rod and transmitter and connect
Receipts machine, which synchronizes, to move up, so that the height of transmitter and receiver is changed, and then realizes transmitter and receiver
It can move in this longitudinal dimension, since sucker can be adsorbed on tunnel roof, be not enough into the portion gas in sucker
Fall sucker, so sucker is still tightly attached on the roof of tunnel；And the opening that controller controls solenoid valve is synchronous, institute
It is synchronous to be located at the height that the transmitter and receiver of stope two sides moves up, to realize transmitter and reception
Machine is always positioned at sustained height, receives the radio wave from transmitter transmitting convenient for receiver.
Due to can be used different size of sucker, sucker it is of different sizes, the attraction of sucker is just different, and use is biggish
Sucker is able to enter the gas flow in sucker in storeroom with regard to larger, thus what piston driving transmitter or receiver moved up
Height is higher；Using lesser sucker, the gas flow being able to enter in sucker in storeroom is just smaller, thus piston driving
The height that transmitter or receiver move up is lower, so can be entered in sucker according to the size of sucker to control storeroom

Processing system can get more comprehensive data information.
When transmitter and receiver is respectively after initial transmissions point and initial receiving point detect, transmitter is moved to
Next launch point, receiver are moved to next receiving point；Or transmitter is fixed on a launch point whithin a period of time,
Receiving point is divided into receiving point section, the different receiving points in mobile receiver to receiving point section, transmitter continuously emits single-frequency
Radio wave, receiver receive the radio wave signal across stope in different receiving points point by point, then, mobile transmitting
Machine is to next launch point, and mobile receiver to different receiving points, receiver will receive every time in next receiving point section
Radio wave signal handled after send accepting/ordering system to, laterally increasing transmitting in this dimension to realize
Machine emits the coverage area of radio wave and the range of receiving of receiver, and then increases the range of detection.
Since connecting rod can slide up and down under the drive of piston along cylinder wall, there is seams between connecting rod and cylinder body
Gap, so can to enter detection by the gap indoor for extraneous gas, so in transmitter transmitting radio wave signal and
It, can be simultaneously to the gas in tunnel positioned at indoor detector is detected during receiver receives radio wave signal
Concentration is detected, for example, the concentration of detection CO2, NO, NO2 or SO2, the gas concentration information that detector will test
Controller is passed to, the gas concentration information received is sent to processing system by controller, and processing system believes gas concentration
Breath carry out processing and the corresponding staff of reminder announced take countermeasure, thus realize to the environment in the tunnels such as coal mine into
Row real time monitoring.

This is applied to the specific course of work of radio wave penetration system under mine are as follows:
When needing to carry out stope perspective detection, start radio wave penetration system all devices, in back production work
Make to arrange multiple launch points in the tunnel of face side, in the multiple receiving points of the roadway layout of the other side of the stope,
Using one of launch point and a receiving point as initial transmissions point and initial receiving point, transmitter 1 is placed on just
Exit point is originated, receiver is placed on initial receiving point, and transmitter 1 is believed by the radio wave that transmitting antenna emits certain frequency
Number, radio wave is propagated in stope, and receiving antenna receives radio wave signal and is converted to electric signal and passes to and connects
Receipts machine, receiver send processing system to after amplifying the processing such as filtering to received electric signal, and processing system is received and solved
Analysis processing radio wave signal.
Wherein, transmitter 1 and receiver are respectively connected with elevating mechanism, and elevating mechanism includes cylinder body 3 and slides with 3 inner wall of cylinder body
The piston 4 of dynamic cooperation, cylinder body 3 are that boundary is divided into storeroom 6 and sensing chamber 7 with piston 4, and piston 4 is located at the side connection of sensing chamber 7
There is the connecting rod 5 stretched out outside cylinder body 3, one end that connecting rod 5 is stretched out outside cylinder body 3 is connect with the transmitter 1 or receiver, is stored
Room 6 is communicated with the sucker 9 that can be adsorbed on tunnel roof 11, is pushed up the tunnel that sucker 9 is pressed on stope using external force
On wall 11, after sucker 9 is tightly attached on tunnel roof 11, the air pressure inside sucker 9 is far smaller than ambient pressure, so extraneous big
Under the action of air pressure, being connected to elevating mechanism and transmitter 1 or receiver below sucker 9 can be suspended in tunnel together, by
In being equipped with detector 8 in sensing chamber 7, certain space measurement gas concentration is needed in sensing chamber 7, so limited block 2
It is arranged and avoids piston 4 and continue to move downward the volume zero for making sensing chamber 7, to is supplied to the enough spaces of sensing chamber 7；
The solenoid valve 10 on transmitter 1 and receiver, the storage completely cut off at this time by solenoid valve 10 are opened simultaneously using controller
Hiding room 6 is connected to sucker 9, and since the air pressure inside sucker 9 is far smaller than ambient pressure, the air pressure in storeroom 6 is atmospheric pressure,
There are pressure differences between sucker 9 and storeroom 6, so the portion gas in storeroom 6 can enter sucker 9 by solenoid valve 10
Interior, the gas in storeroom 6 is reduced, and air pressure reduces, and extraneous atmosphere will push piston 4 and move up, and the mobile of piston 4 can band
Dynamic connecting rod 5 and transmitter 1 or receiver move up, so that the height of transmitter 1 and receiver is changed, Jin Ershi
Having showed transmitter 1 and receiver can move in this longitudinal dimension, since sucker 9 can be adsorbed on tunnel roof 11, enter
Portion gas in sucker 9 is insufficient to allow sucker 9 to fall, so sucker 9 is still tightly attached on tunnel roof 11；And controller
It is synchronous for controlling the opening of solenoid valve 10, so the height that the transmitter 1 and receiver positioned at stope two sides move up
It is synchronous, to realize transmitter 1 and receiver is always positioned at sustained height, receives convenient for receiver from transmitting
The radio wave that machine 1 emits.
Due to can be used different size of sucker 9, sucker 9 it is of different sizes, the attraction of sucker 9 is just different, so energy
It is enough controlled according to the size of control sucker 9 gas that storeroom 6 enters in sucker 9 number, to control transmitter 1 and connect
The mobile height distance of receipts machine.Specifically, the sucker 9 being adsorbed on tunnel roof 11 is entering what certain gas was not fallen out still
Under the premise of, using biggish sucker 9, the gas flow in sucker 9 is able to enter in storeroom 6 with regard to larger, so that piston 4 drives
The height that transmitter 1 or receiver move up is higher；Using lesser sucker 9, it is able to enter in sucker 9 in storeroom 6
Gas flow is just smaller, so that the height that piston 4 drives transmitter 1 or receiver to move up is lower, so using different size of
Sucker 9, it is adjustable for making the height and position of transmitter 1 and receiver, and then makes transmitter 1 and receiver in this longitudinal dimension
The range detected on degree is adjustable；
The height and position of transmitter 1 and receiver can certainly be controlled by adjusting the preset value of timer, such as
The preset value of timer is 30s, and specifically, when controller opens solenoid valve 10, timer starts timing, when timer
When to 30s, timer trigger controller controls solenoid valve 10 and closes, and timer restarts timing, when timer again arrive by timing
When 30s, timer trigger controller controls the opening of solenoid valve 10, which constantly recycles, so that controller controls solenoid valve
10 cycle on and off.Whenever solenoid valve 10 is opened once, the portion gas in storeroom 6 will be flowed into sucker 9, piston
4 just will be shifted up a certain distance, so that the transmitter 1 for being connected to 4 lower section of piston or receiver be made to move up a certain distance, work as electricity
Magnet valve 10 is closed, and the gas stopping in storeroom 6 flows into sucker 9, in timer again 30s this period of timing,
Transmitter 1 can rest on the position transmitting radio wave of the height or receiver and can rest on same height and receive
Radio wave signal, when 30s when timer, terminate, and controller controls the opening of solenoid valve 10, transmitter 1 or receiver again
A certain distance can be moved up again, in such a way that controller cycles on and off solenoid valve 10, and pass through timer
When length of time, control storeroom 6 every time into sucker 9 gas number, it is every to control transmitter 1 and receiver with this
The secondary height moved up；
Transmitter 1 is controlled at various height by way of changing the size of sucker 9 or adjusting timer preset value
Launch point is regarded in position, so as to increase the coverage area that transmitter 1 emits radio wave in this longitudinal dimension, receives
The position that machine can correspondingly be in sustained height with transmitter 1 receives the radio wave emitted from transmitter 1, and then increases
The range of radio wave penetration system perspective detection, enables the processing system get more comprehensive data information.
It is when transmitter 1 and receiver are respectively after initial transmissions point and initial receiving point detect, transmitter 1 is mobile
To next launch point, receiver is moved to next receiving point；
Or transmitter 1 is fixed on a launch point whithin a period of time, receiving point is divided into receiving point section, movement connects
Different receiving points in receipts machine to receiving point section, transmitter 1 continuously transmitting single-frequency radio wave, receiver different receiving points by
Point receives the radio wave signal across stope, and then, mobile transmitter 1 to next launch point connects next
Mobile receiver to different receiving points, receiver passes after being handled each received radio wave signal in sink section
Give accepting/ordering system；And the position of transmitter 1 and receiver in tunnel can be interchanged, and such processing system can intersect
Acquire the data-signal of stope；The variation of transmitter 1 and receiver position lateral in tunnel, realizes in transverse direction
Increase transmitter 1 in this dimension and emit the coverage area of radio wave and the range of receiving of receiver, and then increases detection
Range.
Become position in horizontal and vertical two dimensions in conclusion the invention realizes transmitter 1 and receiver
Change, increases range and receiver that transmitter 1 emits radio wave in horizontal and vertical two dimensions lateral and vertical
Range of receiving in two dimensions, processing system can be obtained according to the radio wave signal of horizontal and vertical two different components
To the more accurate in-built associated technical parameters of stope, the in-built resolution to stope is improved
Ability provides significantly more efficient technical data for safety in production under mine；And the present invention controls transmitter 1 by controller and connects
The gas in elevating mechanism on receipts machine flows into respective sucker 9 simultaneously, keeps transmitter 1 synchronous with the elevating mechanism of receiver
Lifting drives transmitter 1 or receiver to synchronize and move up, and does not need to increase the lifting that additional power removes driving elevating mechanism, save
Additional power source.
Since connecting rod 5 can slide up and down under the drive of piston 4 along 3 wall of cylinder body, exist between connecting rod 5 and cylinder body 3
Gap, so extraneous gas can be entered in sensing chamber 7 by the gap and venthole simultaneously, so in transmitter 1
During emitting radio wave signal and receiver reception radio wave signal, the detector 8 in sensing chamber 7 is same
When the gas concentration in tunnel is detected, for example, the concentration of detection CO2, NO, NO2 or SO2, detector 8 be will test
