Description
Technical field
The present invention relates to coal mining field more particularly to a kind of roof caving coal hydraulic support tail beam sound and vibration data acquisition dresses
It sets.
Background technique
Top coal let-down judges and controls by worker substantially at present, since coal working face dust is big, inclement condition, to existing
Field operator's health and safety threatens, and worker is difficult accurate judgement top coal let-down degree, inevitably leads to push up
It the over-discharge of coal and owes to put.Top plate spoil can largely be released and cause Coal Quality Decline, transport washing increased costs by over-discharge；Owe the meeting of putting
Coal is lost, so that the rate of recovery be caused to reduce.Therefore bastard coal automatic identification is to realize the basis of top coal caving automation, is to mention
High coal mining rate improves Coal Quality, reduces the important means of cost, while being also beneficial to improve worker's working condition, drop
Low human casualty accident improves labor productivity.
Currently, a variety of automatic coal discharge methods have been proposed in academia, but the laboratory demonstration stage is mostly rested on,
The operating condition discussed is fairly simple, used data are also more satisfactory.And coal working face operating condition is severe, operating condition is multiple
Miscellaneous, acquisition various data will receive the interference of various noises so that existing automatic coal discharge method still may not apply to practical life
Among production.Cause such case deeper the reason is that being difficult to acquire a large amount of field datas, and then the actual number based on scene
Good, high reliablity the coal rock detection method according to research and development adaptability.Therefore, develop it is a kind of low cost, without manual intervention, can be long when
Between acquisition, the caving roof coal hydraulic support data acquisition device that easy to use, applicability is high be realize bastard coal automatic identification basis.
It is acquired described in patent CN201520792812 " a kind of fully mechanized coal face be caving petrographic property signal acquiring system "
System needs artificial participate in when carrying out data acquisition on fully-mechanized mining working, it is necessary to select and appoint staff on duty, cannot achieve nobody
Change automatic collection, and when using the acquisition device, need largely to improve existing hydraulic support and upgrade or
Person be using hydraulic support matched with acquisition device, increased again under the premise of acquisition device itself is high-cost use at
This, is unfavorable for the popularization of acquisition device, and that there is also memory capacity is limited, can not disposably acquire a large amount of sound and vibration number
According to the disadvantages of cannot working long hours.
Realize the automatic collection of hydraulic support tail boom sound and vibration data, it is necessary to solve the problems, such as following two:
1. the undistorted acquisition of sound and vibration signal, according to analysis above, the acceleration and vibration that tail boom movement generates are generated
Acceleration property have very big difference, and current vibrating sensor is difficult to accomplish height while high dynamic range, high bandwidth
Precision and low-power consumption；
2. the automatic identification of hydraulic support tail boom movement, starts and stops data to control acquisition device in the suitable time
Acquisition keeps the energy of acquisition device and memory space consumption as small as possible.
Summary of the invention
In order to solve the problems, such as that automatic top coal caving scene sound and vibration data are difficult to acquire, the present invention provides it is a kind of it is low at
This, without manual intervention, can acquire for a long time, the roof caving coal hydraulic support tail beam sound and vibration data that easy to use, applicability is high are adopted
Acquisition means.
When Sub-Level Caving, hydraulic support tail boom is in the moving situation slowly waved up and down, the variation meeting of tail boom pitch angle
The gravitational acceleration component of acquisition device all directions is caused to change；When not putting coal or moving frame, the gravity of tail boom all directions adds
Velocity component variation is unobvious.It is ensured that acceleration of gravity has variation range small (logical in the component of tail boom all directions
Often be not more than 1g, g be unit acceleration of gravity), variation it is slow the features such as.During putting coal, top coal or spoil are fallen hydraulic
On bracket tail boom, tail vibration of beam can be caused, this vibration signal has dynamic range big (usually not less than 10g), signal bandwidth
(typically larger than it is equal to 10kHz) greatly.The present invention proposes dynamic using high-precision, low bandwidth, low-power consumption sensor S1 and high bandwidth, height
The technical solution that state range sensor S2 is combined, the motor message of acquisition hydraulic support tail boom and coal and spoil fall generation respectively
Vibration signal, recycle sound transducer S3 acquisition Sub-Level Caving during voice data.
Further, it is used in order to facilitate scene and achievees the purpose that acquire for a long time, micro controller unit is always with lower
Sample frequency (such as 1Hz) acquisition high-precision, low bandwidth, low-power consumption sensor S1 signal, by the variation of contrast signal,
Or judges whether hydraulic support is in using motion recognition algorithms and put coaly state.If micro controller module judges that hydraulic support is in
It is non-to put coaly state, then the data of high bandwidth, high dynamic range sensor S2 and sound transducer S3 are not acquired, or further will be high
The power supply of bandwidth, high dynamic range sensor S2 and sound transducer S3 and correlation module is closed；Coal is put as hydraulic support is in
State, then microcontroller is with sample rate (such as 48KHz) high bandwidth not less than twice of signal bandwidth, high dynamic range sensor
The data of S2 and sound transducer S3, and store data in the memory inside device.
The present invention reduces the performance indicator requirement to single-sensor by using multi sensor combination, measures meeting
Installation cost is effectively reduced simultaneously in demand.Coaly state is put by automatic identification, and joined low-power consumption under coaly state in non-put
Mode, realizes the sound and vibration automatic data collection of no manual intervention, and reduce the power consumption of device, extends device at the scene
Working time.The present apparatus is powered using battery, is not necessarily to external power supply, without reequiping to existing hydraulic support when using the present apparatus
And upgrading, use cost is reduced, is easy to dispose, the scope of application is wider.In addition acquisition can generate a large amount of sound to the present apparatus for a long time
Vibration data, so storage unit uses large capacity nonvolatile memory.
