Detailed description of the invention
See accompanying drawing 1, which depict the preferred embodiment according to a kind of rock recognition processor of the present invention.
Rock recognition processor is mainly used in Sub-Level Caving or coal mining process, and it can be arranged on the tail boom of caving roof coal hydraulic support or the rocking arm of coal-winning machine accordingly.Rock recognition processor mainly comprises shell, sensor, circuit module, wireless module and battery.Shell is fixedly connected on tail boom or rocking arm, the coal seam softer at coal petrography, vibration is less, can adopt the mode of envelope that magnet is set in housing exterior, shell by magnet adsorption on the tail boom of caving roof coal hydraulic support or the rocking arm of coal-winning machine, to reach fixing object, the coal seam comparatively hard at coal petrography, vibration is larger, installing hole can be set on shell, screw is used fixedly to be tightened on the tail boom of caving roof coal hydraulic support or the rocking arm of coal-winning machine by shell by installing hole, certainly, above-mentioned two kinds of fixing meanss also can be adopted to strengthen fixed effect simultaneously.Shell preferably adopts lighter fire proofing to make, sensor, circuit module, wireless module and battery are arranged on enclosure, shell is totally-enclosed housing, housing does not have external interface, and the connecting sewing everywhere of housing carries out encapsulation process, as sealing ring or fluid sealant fastening, enclosure adopts full embedding to seal, Embedding Material can the common materials such as ring selection epoxy resins, and do the sealing that ensure that processor to greatest extent like this, the dust avoiding down-hole a large amount of is to the infringement of sensor internal device.
Sensor is vibrating sensor or sonic sensor, also can use vibrating sensor and sonic sensor simultaneously, when it is put coal for perception or mine, hydraulic support or coal-winning machine contact produced signal with coal petrography, coal seam is softer and rock is harder, therefore, when being in coal seam, its vibration is less or frequency of sound wave is lower, when being in lithosphere, its vibration is comparatively large or frequency of sound wave is higher, increasing namely along with rock in coal seam, vibration or frequency of sound wave increase gradually, like this, according to the geological condition in current colliery, in conjunction with in coal mining process to the requirement of coal stone ratio, the limit value of vibration or frequency of sound wave can be drawn, when vibrating or frequency of sound wave exceedes limit value, namely think that equipment enters lithosphere.For vibration or the acoustic signals of better receiving equipment, preferably sensor is close to shell and arranges, the gap between shell and sensor uses solid packing to fill and lead up.
Circuit module is used for the signal that described in acquisition and processing, sensor receives, by the noise eliminating to collection signal, filtering and Mathematical Modeling computing, carry out the energy integral of coal and rock identify signal, identify coal petrography mixed proportion, judge to put in coal process whether occurred coarse coal at hydraulic support, or whether encountered rock in coal-winning machine coal cutting process.
Wireless module is electrically connected described circuit module, it is configured with antenna, for the signal after described circuit module process is externally sent with wireless pattern, the coal and rock identify result that described circuit module can be processed is sent to designated equipment and gets on, preferably it has receiving function simultaneously, so that the interchange of inside and outside data also can control rock recognition processor.Battery is used for powering to sensor, circuit module and wireless module, and it is preferably fixed in the chamber of enclosure interior, and is sealed by sealing ring, can be moistureproof, can be convenient for changing again simultaneously.The working method of powered battery and wireless transmission is avoided on hydraulic support or coal-winning machine, reoffer power supply and the maintenance work to cable thereof, avoids simultaneously and offer interface holes on shell.
The Coal-rock identification method of rock recognition processor is as follows:
Hydraulic support open coal discharge outlet carry out putting coal control time, judge whether to be in by the identification of the image data of rock recognition processor and put coal process or notify to carry out coal petrography signals collecting by opening rock recognition processor by the mode of radio communication, and synchronously by circuit module, model computing is carried out to image data, circuit module can comprise high-speed computation and the process that a DPS circuit carries out data, a batch calculation process is carried out for image data, and operation result is reported and submitted on the watch-dog of specifying, the data completing computing can be eliminated, so that vacating space receives new data.When the coal and rock identify data gathered do not put coal feature, automatically can close rock recognition processor, or coal and rock identify process is closed in the instruction that reception external equipment is sent by communication.
The coal and rock identify that above-mentioned rock recognition processor is transmitted hydraulic support is put in coal process and coal-winning machine coal cutting process according to the collection of coal petrography data, process, analysis and result detects, and comprising:
Put in coal process at hydraulic support, rock recognition processor is arranged again on the tail boom of hydraulic support, by constantly reading the data of the sensor, detect being caving of stone, and real-time online testing result wirelessly to be reported and submitted to the hydraulic support control device of specifying or hand-held terminal device, specifically comprise the following steps:
