DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0031] like Figure 1-4 As shown, the coal mine power supply intelligent centralized control system simulation operation platform of the utility model embodiment includes: a display terminal 1, an operating table 2, a wind tube assembly 3 and a controller.

[0032] The display terminal 1 includes a display 11 and a frame 12 . The display 11 is connected to the frame 12 . A tool rack 5 is disposed on the frame 12 . A first sensor 52 is disposed on the tool rack 5 . The first sensor 52 is used to detect whether an instrument is on the tool rack 5 .

[0033] There are multiple operating tables 2, and the multiple operating tables 2 are arranged in sequence and electrically connected.

[0034] The operating console 2 includes a first feed switch 21, a first dual power switch 22, a second feed switch 23, and a first electromagnetic switch 24 which are arranged in sequence. The first feed switch 21, the second feed switch 23, and the first electromagnetic switch 24 are all provided with an isolating switch 27.

[0035] Each isolating switch 27 has an open position and a closed position, and a second sensor 4 is provided at both the open position and the closed position, and the second sensor 4 is used to detect the position of the isolating switch 27. When the isolating switch 27 moves to the open position, the second sensor 4 provided at the open position is triggered. When the isolating switch 27 moves to the closed position, the second sensor 4 provided at the closed position is triggered.

[0036] The wind cylinder assembly 3 includes a wind cylinder 32 and a wind cylinder control box 31 . A wind cylinder state sensor 35 is provided in the wind cylinder 32 . The first dual power switch 22 is electrically connected to the wind cylinder control box 31 .

[0037] The first sensor 52, the second sensor 4 and the wind tube state sensor 35 are all electrically connected to the controller. The controller will label all sensors in advance to determine which position the sensor transmits the signal. The display terminal 1, the operating console 2, and the wind tube assembly 3 are all electrically connected to the controller.

[0038] The instruments include methane concentration detector, electric pen, shutdown maintenance sign, etc.

[0039] There are a variety of training items on the display 11, and different items use different operating tables 2. For example, when training how to use the feed switch, only the first feed switch 21 is used for operation. When training the use and maintenance of the first dual power switch 22, the first feed switch 21 and the first dual power switch 22 are used for operation. When training the use of the wind tube assembly 3, the first feed switch 21, the first dual power switch 22 and the wind tube assembly 3 are used for operation. When training the use and maintenance of the first electromagnetic switch 24, the second feed switch 23 and the first electromagnetic switch 24 are used for operation. As for other items, designers can design according to actual usage scenarios.

[0040] The following describes the training process of trainees using the scenario of repairing the first electromagnetic switch 24 .

[0041] The trainee first selects an item for repairing the first electromagnetic switch 24 on the display 11 .

[0042] Then, exhaust operation is performed, the first dual power switch 22 is started, and the air duct control box 31 is operated to make the air duct 32 start working, so as to simulate the indoor methane-containing air flow to be discharged to the outdoors, and then the methane concentration detector is taken out to detect the methane concentration in the environment. After the methane concentration is within the normal range, the air duct assembly 3 is closed.

[0043] Then, the maintenance operation is performed, and the isolating switch 27 on the second feed switch 23 is moved to the closed position, thereby disconnecting the first electromagnetic switch 24 from the main power supply. Then, the isolating switch 27 on the first electromagnetic switch 24 is moved to the closed position, thereby disconnecting the circuit between the first electromagnetic switch 24 and the second feed switch 23.

[0044] Then hang up the shutdown maintenance sign, take down the electric pen from the frame 12 to inspect the first electromagnetic switch 24. After the inspection is completed, put back the electric pen and the shutdown maintenance sign, and move the isolating switch 27 of the first electromagnetic switch 24 to the open position, and move the isolating switch 27 of the second feed switch 23 to the open position.

[0045] During this process, when the trainee picks up and puts back the methane concentration detector, the electric pen and the shutdown maintenance card, the first sensor 52 will be triggered. When the trainee controls the operation of the wind tube 32, the wind tube state sensor 35 will be triggered. When the trainee operates the isolation switch 27, the second sensor 4 will be triggered.

[0046] The first sensor 52, the wind tube state sensor 35 and the second sensor 4 transmit the detected signals to the controller, which records the signals. The controller is provided with the correct operation sequence, and the controller compares the recorded operation sequence of the trainee with the correct operation sequence. If the two are consistent, the trainee's operation process is correct. If the two are inconsistent, the trainee's operation process is wrong.

[0047] Different training programs correspond to different operation sequences. The controller compares the signal sequence sent by various sensors with the sequence set in the control to determine whether the trainee's operation is correct.

[0048] In the related technology, when training operators, teachers are required to watch the operation process of each operator, which is labor-intensive and time-consuming. In addition, due to factors such as teacher fatigue and subjective judgment, misjudgment is prone to occur.

[0049] The coal mine power supply intelligent centralized control system simulation operation platform of the utility model embodiment can improve the training efficiency by concentrating multiple power supply training projects on the platform, and uses the controller for scoring, making the platform more intelligent.

[0050] The coal mine power supply intelligent centralized control system simulation operation platform of the utility model embodiment sets different operation tables 2 and sets sensors at the operation positions on the operation tables 2, so that the controller can record the trainee's operation process, and then automatically judge whether the operation of the operator is correct, and give the operation result without the teacher's judgment, thereby reducing the teacher's workload and improving the efficiency of training. Moreover, since the controller automatically judges right and wrong, there will be no misjudgment, thereby improving the accuracy of the result and facilitating large-scale training of operators.

[0051] Therefore, the coal mine power supply intelligent centralized control system simulation operation platform of the utility model embodiment has the advantages of high training efficiency and high scoring accuracy.

[0052] Optionally, the second sensor 4 is a position sensor.

[0053] Optionally, the first sensor 52 is a position sensor.

[0054] It should be noted that if Figure 4As shown, the isolating switch 27 has a handle, which is a strip-shaped member. One end of the handle is rotatably connected to the operating table 2, and the other end of the handle can be rotated relative to one end of the handle. After the trained personnel hold the other end of the handle, they can rotate the handle so that the handle moves between the open position and the closed position.

[0055] In some embodiments, Figure 1 As shown, the coal mine power supply intelligent centralized control system simulation operation platform also includes a duct assembly 3, and the duct assembly 3 also includes a mounting frame 30, on which a first fan 33 and a second fan 34 are provided. A duct control box 31 is installed on the mounting frame 30, and the first fan 33 and the second fan 34 are both electrically connected to the duct control box 31.

[0056] In some embodiments, Figure 1 As shown, the wind tube 32 includes a first wind tube 321 , which is provided with a first port 3211 and a second port 3212 , the first port 3211 is connected to the first fan 33 , a gas sensor 36 is provided at the second port 3212 , and a wind tube state sensor 35 is provided inside the first wind tube 321 .

[0057] The material of the air cylinder 32 is rubber, and the air cylinder state sensor 35 can be used to detect whether the air volume in the air cylinder 32 is normal.

[0058] The gas sensor 36 is used to detect the gas concentration in the exhaust airflow. In actual operation, the speed of the fan is adjusted according to the value of the gas sensor 36. When the gas sensor 36 measures a high gas concentration, the fan is accelerated, and when the gas sensor 36 measures a low gas concentration, the fan is decelerated. During training, since there is no gas in the training room, the value of the gas sensor 36 is almost zero. Therefore, the simulation operation platform of the coal mine power supply intelligent centralized control system of the embodiment of the utility model does not need to assess the project of adjusting the fan speed.

[0059] In some embodiments, Figure 1 As shown, the air duct 32 also includes a second air duct 322 , on which a third port 3221 and a fourth port 3222 are provided, the third port 3221 is connected to the second fan 34 , a connecting port 3213 is provided between the first port 3211 and the second port 3212 , and the fourth port 3222 is connected to the first air duct 321 through the connecting port 3213 .

[0060] For example, the mounting frame 30 is provided with multiple layers of compartments arranged up and down, and the first fan 33 and the second fan 34 are both arranged in the compartments. The first fan 33 is arranged below the second fan 34, and the start buttons of the first fan 33 and the second fan 34 are arranged in the wind tube control box 31. The second fan 34 is used as a backup fan. When the wind tube assembly 3 is running, the first fan 33 is started and the second fan 34 is not started. When the first fan 33 fails and is damaged, the second fan 34 is started.

[0061] Therefore, when the first fan 33 fails during training, the trainees can continue to use the second fan 34 for training, so that the training of the trainees will not be affected.

[0062] Optionally, the air cylinder state sensor 35 is arranged between the connection port 3213 and the inlet of the air cylinder 32 .

[0063] The coal mine power supply intelligent centralized control system simulation operation platform of the utility model embodiment is a simulation training, so the wind tube assembly 3 can be completely arranged indoors, and there is no need to arrange the air outlet of the wind tube assembly 3 outdoors, and only related operations need to be simulated.

[0064] In some embodiments, Figure 1 As shown, each operating table 2 is provided with a cabinet 25 and a table 26, the cabinet 25 is detachably connected to the table 26, the cabinet 25 includes a first part (not shown in the figure), and the table 26 includes a second part (not shown in the figure). When the cabinet 25 is closed, the first part and the second part are arranged opposite to each other, and the second part is provided with a cabinet sensor (not shown), and the cabinet sensor is electrically connected to the controller.

[0065] For example, the operating table 2 has electrical components inside, and in some projects, the cabinet 25 needs to be disassembled to inspect the electrical components inside. The first part is arranged at the outer edge of the cabinet 25, and the second part is arranged at the outer edge of the table 26. When the cabinet 25 is closed, the first part and the second part can contact each other.

[0066] When the cabinet 25 is not disassembled, the first part can contact the cabinet sensor on the second part. When the cabinet 25 is disassembled, the first part is separated from the second part, and the first part is also separated from the cabinet sensor. The signal of the cabinet sensor changes, and the cabinet 25 sensor transmits the signal to the controller. The controller can record the signal to determine whether the trainee has completed the disassembly of the cabinet 25.

[0067] After completing the relevant work, the trainee installs the cabinet 25. At this time, the first part contacts the second part, and the first part can contact the cabinet sensor on the second part, causing the signal of the cabinet sensor to change again. The cabinet 25 sensor transmits this signal to the controller, and the controller can record the signal to determine whether the trainee has completed the installation of the cabinet 25.

[0068] Optionally, the cabinet sensor is a pressure sensor, and when the first part contacts the second part, the first part can transmit pressure to the second part, and when the first part separates from the second part, the first part leaves the cabinet sensor, thereby causing a change in the signal of the cabinet sensor.

[0069] Optionally, a protrusion is provided on the first part, so as to increase the pressure on the second part when the cabinet 25 is closed.

[0070] In some embodiments, Figure 2 As shown, the tool display rack 5 includes a shell 51, a cavity is provided in the shell 51, and the shell 51 includes a top plate 511. The top plate 511 is recessed into the shell 51 to form a groove 512. The groove 512 is used to place instruments, and a first through hole is provided at the bottom of the groove 512.

[0071] For example, the meter is a methane concentration detector, an electric pen, etc. The meter is installed in the groove 512, thereby facilitating the standardized placement of the meter.

[0072] A plurality of tool racks 5 are provided.

[0073] In some embodiments, the tool display rack 5 also includes a first sensor 52, which is disposed in the cavity. The first sensor 52 includes a trigger member 521 and a detection member 522. The trigger member 521 is disposed above the detection member 522. The trigger member 521 can move in the up and down directions relative to the first through hole. The trigger member 521 has a first position and a second position. In the first position, one end of the trigger member 521 extends out of the first through hole to the groove 512, and the other end of the trigger member 521 is separated from the detection member 522.

[0074] In the second position, one end of the trigger member 521 is retracted into the first through hole, and the other end of the trigger member 521 is in contact with the detection member 522 .

[0075] In some embodiments, Figure 2 As shown, the first sensor 52 further includes a first restoring member 523 , and the first restoring member 523 has a force that causes the trigger member 521 to return to the first position.

[0076] For example, the detection member 522 is electrically connected to the controller, the trigger member 521 is a cylindrical rod, the trigger member 521 is a metal member, and the detection member 522 is a sensor based on the Hall effect. When the trigger member 521 contacts or separates from the detection member 522, the magnetic field of the detection member 522 changes, thereby causing the signal detected by the controller to change.

[0077] When no instrument is placed in the groove 512, the trigger member 521 is in the first position. When an instrument is placed in the groove 512, the instrument causes the trigger member 521 to move downward, so that the trigger member 521 moves from the first position to the second position, thereby causing the signal of the detection member 522 to change. After the trainee takes out the instrument, the trigger member 521 returns to the first position under the action of the first reset member 523, thereby causing the signal of the detection member 522 to change again.

[0078] Therefore, the signal of the first sensor 52 detected by the controller can determine whether the trainee uses the relevant instrument.

[0079] In some embodiments, Figure 2 As shown, the first sensor 52 includes a base 524, a ring groove 5241 is provided on the base 524, the detection member 522 is arranged on the inner side of the ring groove 5241, the trigger member 521 is provided with an annular portion 5211, the diameter of the annular portion 5211 is larger than the diameter of the first through hole, one end of the first reset member 523 is arranged in the annular groove 5241, and the other end of the first reset member 523 abuts against the annular portion 5211.

[0080] For example, an annular portion 5211 is provided on the outer peripheral side of the trigger member 521, the annular portion 5211 is provided at the middle and upper part of the trigger member 521, and the annular portion 5211 is an annular plate. The first reset member 523 is a spring. The lower end of the first reset member 523 is embedded in the annular groove 5241, and the upper end of the first reset member 523 is against the lower end of the annular portion 5211. On the one hand, the annular portion 5211 can prevent the trigger member 521 from completely sliding from the first through hole to the groove 512, and on the other hand, the annular member is connected to the first reset member 523 so that the trigger member 521 can be automatically reset.

[0081] Optionally, a recess 5242 is provided in the middle of the base 524 , and the detection member 522 is provided in the recess 5242 . When in the second position, the lower end of the trigger member 521 can extend into the recess 5242 and contact the detection member 522 . When in the first position, the lower end of the trigger member 521 leaves the recess 5242 .

[0082] It should be noted that the parking sign is generally light in weight. If the first sensor 52 can be triggered, the first sensor 52 is used. If the first sensor 52 cannot be triggered, the first sensor 52 can be replaced by a gravity sensor for the parking sign.

[0083] In some embodiments, the second sensor 4 includes a sensor body 41, a connector 44, a first bolt 42, and a second bolt 43. The outer peripheral side of the sensor body 41 is provided with a thread. The connector 44 includes a first connecting portion 441 and a second connecting portion 442. The first connecting portion 441 and the second connecting portion 442 are generally L-shaped. The first connecting portion 441 is provided with a mounting hole. The sensor body 41 is arranged in the mounting hole. The second connecting portion 442 is detachably connected to the operating table 2.

[0084] The first bolt 42 and the second bolt 43 are both threadedly connected to the sensor body 41 , and the first bolt 42 , the first connecting portion 441 , and the second bolt 43 are sequentially arranged in the axial direction of the sensor body 41 .

[0085] For example, the connecting member 44 is made of a strip plate bent into an L shape, the sensor body 41 is installed in the mounting hole, and then the upper and lower ends of the sensor body 41 are fixed by the first bolt 42 and the second bolt 43 to prevent the sensor body 41 from falling off from the mounting hole.

[0086] The second connection portion 442 is connected to the operating platform 2 via bolts.
