Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic composition diagram of a coal mine mining machine operation skill training system according to an embodiment of the present invention. As shown in fig. 1, the training system includes a signal collector 1, an upper computer 2, a controller 3, and an indicator 4.
Generally, coal mining is performed by matching a fully-mechanized coal mining machine and a coal mining machine in sequence, the fully-mechanized coal mining machine is used for driving coal out of a channel, then the coal mining machine is used for cutting a coal mine, and finally the cut coal mine is transported away from a mining surface.
The signal collector 1 is used for collecting a movement track or a movement position signal of the mining machine.
In actual coal mining, the fully-mechanized excavating machine needs to open passages with different shapes according to needs, so that a tool bit motion track and relative positions of the tool bit relative to upper, lower, left and right walls of a motion tunnel need to be obtained during operation skill training of the fully-mechanized excavating machine, and the signal collector 1 comprises a correlation sensor and an ultrasonic ranging sensor. The emission sensors and the ultrasonic ranging sensors are arranged in an array manner in a one-to-one team, the motion track and the relative position signal of the mining machine in the operation space with the same area of the array are detected, and the motion track and the relative position signal are sent to the controller 3. The transmitting end of the sensor is arranged on the cutter head and used for acquiring the motion track and the relative position of the cutter head in real time, and the receiving end of the sensor is arranged on the electronic curtain and used for displaying the motion track of the cutter head of the roadheader. The receiving ends of the sensors are arranged on the electronic curtain in an array mode, and are used for detecting the motion track signals of the comprehensive excavator tool bit in the operation space with the same area as the array and sending the motion track signals to the controller 3. The movement track of the fully-mechanized excavating machine tool bit in the space is collected through the correlation sensor and the ultrasonic distance measuring sensor, so that the footage of the fully-mechanized excavating machine can be accurately detected.
The coal mining machine is a mining machine which breaks down coal from a coal body (breaking coal) by a working mechanism and loads the coal into a working face conveyor (charging coal). The cutting accuracy of the shearer affects the safety and coal mining quality of coal mining, and therefore requires the shearer operator to accurately control the cutting position of the drum. In order to simulate the cross section of the underground coal seam and achieve high training level for students, three groups of mining height levels are set, wherein the distance between the first level and the second level is 30mm, and the distance between the second level and the third level is 50 mm. Below the first level is insufficient mining height, above the first level below the second level is perfect operation, above the second level below the third level is overstock, above the third level is operation failure. The setting of the number of the mining height levels and the setting of the distance between the two coal mining levels can be adjusted correspondingly according to the actual requirements of training, for example, more mining height levels can be set when trainees are trained at high levels, and the distance between the two mining height levels can be set to be larger when the requirements are lower. Aiming at the operation requirements of the coal mining machine, the signal collector 1 is arranged into an infrared sensor array, collects the movement position signals of the coal mining machine relative to three mining levels, and sends the movement position signals to the controller 3.
An industrial control program is arranged in the upper computer 2 and used for sending out control signals. The upper computer 2 is a computer capable of directly sending a control command, in the embodiment of the application, the upper computer 2 is a computer and a mobile intelligent device and is also used for sending a control signal, and a corresponding controlled object is the controller 3.
The controller 3 is in communication connection with the signal collector 1 and the upper computer 2, the controller 3 receives a control signal sent by the upper computer 2, and the controller 3 controls the correlation sensor and the ultrasonic distance measuring sensor to carry out motion trail or controls the infrared sensor array to carry out motion position signal collection according to the control signal by combining a logic program arranged in the controller 3. The controller 3 receives the motion track or the motion position signal, processes the motion track or the motion position signal and sends out an instruction signal, wherein when the motion track or the motion position is consistent with a preset motion track or a preset motion position within a preset range, the controller is used for sending out a first instruction signal, and when the motion track or the motion position is inconsistent with the preset motion track or the preset motion position within the preset range, the controller is used for sending out a second instruction signal and converting the instruction signal into a photoelectric signal. The determination of the preset range can be correspondingly adjusted according to the actual requirements of training, and in addition, the preset ranges with different levels can be set to distinguish more detailed operation levels, for example, for a new student, the preset range can be properly expanded as long as the action can be basically finished; and in the skill assessment stage, different grades can be set in the preset range so as to better distinguish the difference of the operation levels of different personnel. It should be noted that, for the number of levels in the preset range, the corresponding first instruction signal and second instruction signal may also be divided into more sub-divisions, for example, the first instruction signal is divided into one level, two levels, three levels, and so on. In addition, the preset range is also embodied differently when the machine operates differently, for example, for the comprehensive excavator, because a track with a certain shape is required to be cut, a certain number of sampling points are arranged on the preset track, a student is required to accurately operate the comprehensive excavator to enable the cutter head to pass through the sampling points, and the operation level of the student can be evaluated according to the percentage of the passing sampling points, for example, the 100% passing is full, and the 60% passing is passing. And for the coal mining machine, the operation level of the trainee is evaluated through different set coal mining horizontal lines, wherein the coal mining height is insufficient below the first level, the perfect operation is performed below the first level and the second level, the coal mining height is over-limit and the operation failure is performed above the third level, and the coal mining height is not enough.
Further, in order to improve reliability, accuracy and stability of the system of the embodiment of the application. Fig. 2 is a schematic diagram of a controller of a coal mining machine operational skill training system according to an embodiment of the present invention. As shown in fig. 2, the controller 3 includes a PLC programmable controller 31, an ethernet unit 32, an isolation barrier 33, a relay module 34, and a power supply 35. The PLC 31 is provided with a training or checking logic program and is used for sending out an instruction signal; the ethernet unit 32 is used for realizing information and instruction transmission between the PLC programmable controller 31 and the upper computer 2; the isolation gate 33 is used for isolating the PLC 31 from the signal collector 1; the relay module 34 is used for converting the instruction signal into a photoelectric signal; and the power supply 35 is used for providing working voltage for the signal collector 1, the isolation grid 33 and the relay module 34.
And the indicator 4 is in communication connection with the controller 3 and is used for receiving the instruction signal, displaying the motion track or the motion position and sending out a reminding signal, when the indicator 4 receives the first instruction signal, the first reminding signal is sent out, and when the indicator 4 receives the second instruction signal, the second reminding signal is sent out.
The signal collector 1 of the roadheader collects the movement track of the cutter head through a correlation sensor and an ultrasonic distance measuring sensor, and therefore, the indicator 4 comprises: the electronic curtain, the LED indicator light and the loudspeaker; the electronic curtain is made of movable steel and used for arranging the LED indicating lamps; the LED indicating lamps are arranged in an array mode and are used for displaying the preset movement track and the movement track of the fully-mechanized excavating machine; and the loudspeaker is used for sending out a reminding signal. The indicator 4 is used for displaying a preset motion track and an actual motion track by arranging an LED indicator lamp array on the electronic curtain. When the indicator 4 receives a first instruction signal, namely the actual motion track is consistent with the preset motion track in the preset range, the indicator 4 sends a first reminding signal, namely the LED indicator lamp through which the actual motion track passes displays green to indicate 'pass', and meanwhile, the horn sends a reminding signal; when the indicator 4 receives the second instruction signal, that is, the actual motion track is not matched with the preset motion track in the preset range, the indicator 4 sends a second reminding signal, that is, the LED indicator light through which the actual motion track passes displays red color to indicate that the operation is "wrong", the corresponding loudspeaker broadcasts the operation result, and the trainee can obtain the operation condition of the trainee through the display picture of the indicator light on the electronic curtain and the sound broadcast. Further, the LED indicator lamp correspondingly selects the multi-color display lamp for the number of levels divided by the first command signal from the controller 3 to recognize different operation levels with different colors.
The signal collector 1 of the coal mining machine collects the movement position of a roller of the coal mining machine through an infrared sensor array, and then aiming at the arrangement of the coal mining height level, an indicator 4 is provided with indicator lamps at different coal mining height line positions. Thus, the indicator 4 comprises: a double-color indicator light and a horn; the double-color indicator lamps are correspondingly arranged with the infrared sensor arrays one by one and used for indicating the movement position of the coal mining machine. When the indicator 4 receives the first instruction signal, the fact that the actual movement height is consistent with the preset movement position within the preset range is indicated, the indicator 4 sends out a first reminding signal, namely all green indicator lamps are always on to indicate that the green indicator lamps pass, and the corresponding loudspeakers broadcast the operation result; when the indicator 4 receives the second instruction signal, it indicates that the actual movement height is inconsistent with the preset movement position within the preset range, and then the indicator 4 sends a second reminding signal, that is, the red indicator light at the corresponding position is on, indicating "error", and the corresponding horn broadcasts the operation result. More specifically, when the mining height is not enough below the first level, the red indicator lamp corresponding to the first level is normally on; a first level higher than the first level and a second level lower than the second level is perfect operation, and all indicator lights are not on; the mining height exceeding limit is higher than the second level and lower than the third level, and a red indicator lamp at the second level is normally on; if the operation is failed, the operation of the coal mining machine is stopped, and the red indicator light at the third level is always on.
