Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mine safety equipment, especially to a mine locomotive electronic fence device. BACKGROUND

[0002] In the mining operation, the mine locomotive as an important transport tool, its operation safety is crucial. The mine locomotive electronic fence device emerges as the times require, aims at effectively limiting and monitoring the operation range of the locomotive, preventing it from entering the dangerous area, so as to protect the safety of personnel and equipment, and optimize the production process.

[0003] However, the existing traditional mine locomotive electronic fence device has many defects, which seriously affects its performance and reliability, and is difficult to meet the needs of modern mine safety production.

[0004] First of all, in terms of positioning accuracy, the traditional device mostly relies on technologies such as radio frequency identification (RFID), and its accuracy is usually at the level of meters. In the complex underground environment of the mine, affected by factors such as numerous metal equipment and strong electromagnetic interference, the positioning error can reach 3-5 meters or even more. This makes it impossible to accurately determine whether the locomotive has actually crossed the preset safety boundary near the key areas such as the intersection of narrow tunnels and the boundary of dangerous areas, greatly weakening the protection effectiveness of the electronic fence.

[0005] Secondly, the weak anti-interference ability is a big problem of the traditional device. The underground mine is full of various high-power electrical equipment, such as coal mining machines, scraper conveyors and ventilators, etc. The strong electromagnetic interference generated by them when running often overlaps with the signal frequency band of the electronic fence device. At the same time, the high humidity and dusty environment in the mine also erodes the electronic components and signal transmission lines of the device, leading to signal distortion, misjudgment or even loss, seriously threatening the accuracy and stability of the locomotive operation safety monitoring.

[0006] Thirdly, the flexibility and adaptability of the traditional electronic fence device are poor. With the advancement of mining, the layout of the tunnel and the working area will be adjusted, and the existing device needs to consume a lot of manpower for on-site debugging and re-wiring and other tedious operations when re-planning the fence area. This not only is low in efficiency, but also makes the device unable to work normally during the adjustment period, greatly affecting the continuous production efficiency and safety of the mine.

[0007] In addition, the real-time performance of the traditional device also has obvious shortcomings. Due to the relatively backward communication protocol and data processing method, when the locomotive triggers the electronic fence boundary, the alarm information often cannot be transmitted to the monitoring center in time, with a delay time of several seconds or even longer. This delay may make the locomotive stay in the dangerous area for too long in case of emergency, significantly increasing the risk of accidents, and cannot meet the requirements of real-time monitoring and rapid response of the locomotive operation state.

DETAILED DESCRIPTION

[0022] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0023] The mine locomotive electronic fence device is described below in combination with the drawings.

[0024] As Figure 1 shown, the mine locomotive electronic fence device can comprise: a high-precision positioning unit 10, the high-precision positioning unit 10 can comprise a plurality of UWB positioning base stations 11, a data transmission module 12 and an inertial navigation system 13, wherein the plurality of UWB positioning base stations 11 are distributed in a mine roadway and are in communication connection with a UWB positioning tag installed on a mine locomotive through wireless signals to obtain mine locomotive position information in real time, and the positioning accuracy reaches a decimeter level. For example, the plurality of UWB positioning base stations 11 can be 2, 3, 4, 5, 6 UWB positioning base stations 11, etc., and the specific number of settings can be selected according to actual conditions, which is not limited herein, and each UWB positioning base station 11 is connected to the data transmission module 12 through a cable.

[0025] In the embodiment of the present application, in the mine roadway, the plurality of UWB positioning base stations 11 can be distributed at positions such as both sides and the top of the roadway. When the mine locomotive is running, the UWB positioning tag sends out signals and communicates with the UWB positioning base station. The UWB positioning base station transmits the positioning information to the data transmission module 12 through a cable.

[0026] The inertial navigation system 13 is arranged on the mine locomotive, and the inertial navigation system 13 is connected with the data transmission module 12.

[0027] The anti-interference communication unit 20 is connected with the data transmission module 12.

[0028] It should be noted that the anti-interference communication unit 20 described in this embodiment works in a frequency band free from electromagnetic interference of electrical equipment in a mine, and is used to transmit the locomotive position information to the intelligent monitoring host 30. The intelligent monitoring host 30 is pre-set with electronic fence boundary parameters for receiving and processing the locomotive position information, and sends out an alarm instruction when the locomotive position information shows that the locomotive approaches or crosses the pre-set electronic fence boundary.

[0029] The intelligent monitoring host 30 is arranged in a monitoring center and is connected with the anti-interference communication unit 20, and is used to receive and process the locomotive position information transmitted by the anti-interference communication unit 20. The intelligent monitoring host 30 is pre-set with electronic fence boundary parameters inside, which are stored in the storage unit of the host in a digital form. When the locomotive position information is processed and shows that the locomotive approaches or crosses the pre-set electronic fence boundary, the control unit of the intelligent monitoring host 30 can timely send out an alarm instruction.

[0030] The alarm unit 40 is connected with the intelligent monitoring host 30 and is used to alarm through sound and light after receiving the alarm instruction.

[0031] Specifically, the UWB positioning base station 11 is installed in the mine tunnel, the position is ensured to be accurate, and the UWB positioning tag of the locomotive is communicated. Meanwhile, the inertial navigation system 13 and the data transmission module 12 are installed, the connection with the UWB positioning base station 11 and the anti-interference communication unit 20 is ensured to be normal, and the system is debugged to ensure that each module works normally.

[0032] When the locomotive starts to run, the UWB positioning base station 11 monitors the position information of the locomotive in real time, and transmits the position information to the anti-interference communication unit 20 through the data transmission module 12. The anti-interference communication unit 20 processes and enhances the signal, and then sends the signal to the intelligent monitoring host 30. The intelligent monitoring host 30 monitors the position information of the locomotive in real time, and processes according to the preset electronic fence boundary parameters. When the locomotive position information shows that the locomotive approaches or crosses the preset electronic fence boundary, the intelligent monitoring host 30 sends an alarm instruction. After the alarm unit 40 receives the alarm instruction, an alarm signal is sent.

[0033] In an embodiment of the utility model, as shown in Figure 1 The inertial navigation system 13 can include an accelerometer 131, a gyroscope 132, a magnetometer 133, a circuit board 134 and a microprocessor 135, wherein the accelerometer 131, the gyroscope 132 and the magnetometer 133 are connected with the microprocessor 135 through the circuit board 134 respectively; and the microprocessor 135 is connected with the data transmission module 12.

[0034] It can be understood that when the mine locomotive drives in the tunnel, the high-precision positioning unit monitors the position and motion state of the locomotive in real time when the locomotive approaches or enters a dangerous area (such as approaching the edge of the tunnel, a specific safety area, etc.). The inertial navigation system obtains the motion data of the locomotive through the accelerometer, the gyroscope and the magnetometer, and improves the positioning accuracy in combination with the positioning information of the UWB positioning base station.

[0035] In an embodiment of the utility model, as shown in Figure 1 The anti-interference communication unit 20 can include a signal enhancement module 21 and a frequency hopping spread spectrum communication module 22, the signal enhancement module 21 is connected with the frequency hopping spread spectrum communication module 22 and the data transmission module 12 respectively, and the signal enhancement module 21 and the frequency hopping spread spectrum communication module 22 are connected with the intelligent monitoring host 30 respectively.

[0036] It should be noted that the frequency hopping spread spectrum communication module 22 described in this embodiment has a dynamic frequency adjustment function, can automatically select the optimal communication frequency band according to the underground electromagnetic interference, simultaneously adopts a forward error correction coding technology to correct and encode the transmission data, improves the transmission reliability, reduces the bit error rate, has an automatic reconnection and data retransmission mechanism after communication interruption, and guarantees that the monitoring center obtains complete locomotive position information.

[0037] In an embodiment of the present application, as shown in Figure 2 The mine locomotive electronic fence device further comprises a visual operation interface 50, which is arranged in a monitoring center and connected with the intelligent monitoring host 30, wherein the visual operation interface 50 displays the mining progress and regional changes through a graphical interface, allows the user to adjust the electronic fence boundary parameters according to the actual situation, and records and stores the running track and alarm information of the mine locomotive in real time.

[0038] In an embodiment of the present application, as shown in Figure 1 The alarm unit 40 can include a sound alarm component 41, a light alarm component 42 and an information sending component 43, wherein the sound alarm component 41 is connected with the audio output interface of the intelligent monitoring host 30, and is used for emitting different sounds.

[0039] The light alarm component 42 is connected with the light control interface of the intelligent monitoring host 30, and alarms in the form of flashing light. The light alarm component 42 can adopt high-brightness and low-power LED lights, and can display different colors to distinguish the alarm conditions.

[0040] The information sending component 43 is connected with the communication interface of the intelligent monitoring host 30, and sends the alarm information through the internal communication network of the mine.

[0041] It can be understood that after the alarm unit 40 receives the alarm instruction, the sound alarm component 41 emits different sounds, the light alarm component 42 alarms in the form of flashing light, and the information sending component 43 sends the alarm information to the relevant personnel through the internal communication network of the mine. For example, when the locomotive approaches or crosses the preset electronic fence boundary, the sound alarm component 41 will emit a high-frequency alarm sound, the light alarm component 42 will flash red light, and the information sending component 43 will send a short message or voice notification to the relevant personnel.

[0042] Specifically, when the mine locomotive drives in the tunnel, the UWB positioning base station 11 communicates with the UWB positioning tag, determines the position of the locomotive by measuring the time of flight of the signal. At the same time, the inertial navigation system 13 obtains the motion data of the locomotive through the accelerometer 131, the gyroscope 132 and the magnetometer 133, supplements and corrects the position of the locomotive, and improves the positioning accuracy.

[0043] The anti-interference communication unit 20 selects the optimal communication frequency band automatically according to the underground electromagnetic interference through the frequency hopping spread spectrum communication module 22, and uses the forward error correction coding technology to correct and encode the transmission data, thereby improving the reliability of data transmission. The signal enhancement module 21 performs enhancement processing on the signal to ensure stable transmission of the signal in complex environment.

[0044] The intelligent monitoring host 30 receives the locomotive position information transmitted by the anti-interference communication unit 20, and compares the position information with preset electronic fence boundary parameters. When the position information of the locomotive shows that the locomotive approaches or crosses the preset electronic fence boundary, the intelligent monitoring host 30 sends an alarm instruction.

[0045] After receiving the alarm instruction, the alarm unit 40 sends out different sounds through the sound alarm component 41, flashes light through the light alarm component 42, and sends alarm information to relevant personnel through the information sending component 43 through the internal communication network of the mine. The management personnel can understand the position and running state of the locomotive in real time through the visual operation interface 50, and take timely measures for processing.

[0046] Further, the electronic fence device for the mine locomotive described above can further include a power module (not shown in the figure), which is connected with the plurality of UWB positioning base stations 11, the circuit board 134, the signal enhancement module 21, the frequency hopping spread spectrum communication module 22, the intelligent monitoring host 30, the sound alarm component 41, the light alarm component 42 and the information sending component 43 through power lines. The power module is used to provide stable power supply for each unit, and ensure the normal operation of the device.

[0047] In summary, the electronic fence device for the mine locomotive according to the embodiments of the present application can realize high-precision positioning and safety monitoring of the mine locomotive through the cooperative work of the high-precision positioning unit, the anti-interference communication unit, the intelligent monitoring host and the alarm unit, and effectively improve the safety management level of the mine.
