Technical Field

[0001] This invention relates to the field of high-voltage switchgear technology, and in particular to a high-voltage switchgear for coal mine power supply and its operation method based on a mine power system. Background Technology

[0002] With the development of human power industry, there are more and more high-voltage switchgear for electricity. In production, power plants, substations and power distribution rooms of industrial and mining enterprises all use high-voltage switchgear to receive and distribute electrical energy. Because there are many high-voltage switchgear in mines and their locations are relatively hidden, they are extremely difficult to find in the complex environment of coal mines.

[0003] Therefore, a high-voltage switchgear for coal mine power supply and its operation method based on the mine power system are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a high-voltage switchgear for coal mine power supply and its operation method based on a mine power system, so as to solve the problem mentioned in the background art that high-voltage switchgear is difficult to find in coal mines.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-voltage switchgear for coal mine power supply and its operation method based on a mining-based system, comprising a device body, a central control center, and a computing device. The device body is equipped with a power supply and a controller. The power supply and controller are linearly connected. The controller is data-connected to the central control center. The central control center is data-connected to the computing device. The core processing units of the controller, the central control center, and the computing device are all mining-based core boards. The invention is characterized in that... Inside the device body, there are temperature sensors and position sensors. The temperature sensors and position sensors are linearly connected to the controller and electrically connected to the power supply through the controller. LoRa positioning tags are installed inside the temperature sensors and position sensors. A LoRa gateway is set up between the central control center and each group of equipment. The LoRa positioning tag is independently connected to the LoRa gateway. An auxiliary system is set up on the central control center. The temperature sensor, position sensor and LoRa gateway are connected to the auxiliary system through an industrial ring network. The auxiliary system is connected to the computing device through an industrial ring network. The temperature sensor, position sensor, and core processing unit of the LoRa gateway are also based on the Miningcore board.

[0006] Preferably, the auxiliary system includes a data receiving module, a big data module, an analysis module, a map module, a positioning module, a network module, and a device transmission module, wherein; The data receiving module is connected to the temperature sensor and the position sensor, and is used to receive temperature data and orientation data transmitted by the temperature sensor and the position sensor. The big data module is used to connect to the big data network to obtain atmospheric temperature information in real time and to assist the analysis module in analysis. The analysis module is used to combine temperature data, atmospheric temperature information and azimuth data to analyze and determine the equipment operation strategy. The map module is used to construct a map on a GIS based on existing spatial sites and big data modules; The positioning module is used to display the location of the device body on the map in real time based on the orientation data; The network module is used to provide a network foundation for data connections between various components, modules, and devices; The device communication module is connected to the computing device and is used to transmit data signals to the computing device or receive control data transmitted by the computing device.

[0007] Preferably, the positioning module is also connected to the LoRa gateway and receives location data detected by the LoRa positioning tag transmitted from the LoRa gateway. The orientation data includes two-dimensional point data of the device body, and the location data includes three-dimensional point data of the device body.

[0008] Preferably, the map module constructs two-dimensional maps and three-dimensional maps on the GIS: When the positioning module displays the device itself on the two-dimensional map, the positioning module only displays the location of the device itself on the two-dimensional map based on the location data; When the positioning module displays the device body on the 3D map, it combines location data and orientation data to display the location of the device body on the 3D map.

[0009] Preferably, the vertical distance between the position sensor and the stability sensor is fixed. The auxiliary system also includes a false detection module. After the positioning module receives the orientation data from the temperature sensor and the position sensor, the false detection module checks the orientation data of the temperature sensor and the position sensor. If the horizontal distance between the two is similar and the vertical distance is similar to the fixed value, the orientation data is correct. If the horizontal distance between the two is not equal, but the vertical distance is similar to the fixed value, the horizontal distance is compared with the position data, and the orientation data with the horizontal distance similar to the position data is selected. If the horizontal distance between the two is not equal and the vertical distance is not equal to the fixed value, an alarm message indicating a position error is sent to the computing device through the device communication module.

[0010] Preferably, the auxiliary system further includes a control module, which is connected to the computing device via a device communication module. The control module is used to receive data signals transmitted by the analysis module and the device communication module, and to control the operation of the device body based on the data signals.

[0011] Preferably, when the analysis module determines the device's operating strategy, it also incorporates location data for further judgment. During the judgment, it uses big data network to assist in the judgment. Specifically, it uses big data network combined with atmospheric temperature information, orientation data, and location data to determine the external temperature at the device's location and compares the external temperature with the temperature data. If the temperature difference is small, the machine operates according to the original strategy. If the temperature data is greater than the external temperature, a strategy of reducing the current and voltage output of the device is used, and this strategy information is transmitted to the computing device for display through the device communication module.

[0012] Preferably, after receiving the control data, the device transmission module transmits the control data to the control module, and the control module controls the start and stop of the device body after receiving the control data.

The auxiliary system analyzes and locates data using location data, orientation data, temperature data, atmospheric temperature information, two-dimensional maps, and three-dimensional maps. S3. The operator controls the operation of the equipment body and observes the position of the equipment body through the computing device.

[0014] A computing device, with a mining core board as the core processing unit, is connected to an auxiliary system via an industrial ring network and equipped with a touch-screen display. The computing device receives data signals transmitted by a device communication module and transmits these signals to the display screen. If an operator initiates control by touching the display screen, the computing device transmits the control data to the device communication module. The computing device can also directly acquire two-dimensional and three-dimensional map data via the industrial ring network and display them on the screen.

[0015] The beneficial effects of this invention are: 1. This invention uses a position sensor to detect directional data, and LoRa tags and LoRa gateways work together to detect location data, providing a data foundation for locating high-voltage switchgear.

Example

[0022] like Figures 1 to 4 As shown in the figure, a specific embodiment of the present invention provides a high-voltage switchgear for coal mine power supply and its operation method based on a mining-based system. The switchgear includes a main body 1, a central control center, and a computing device. The main body 1 is equipped with a power supply and a controller. The power supply and controller are linearly connected, the controller is data-connected to the central control center, and the central control center is data-connected to the computing device. The core processing units of the controller, the central control center, and the computing device are all mining-based core boards. Inside the device body 1, there is a temperature sensor 2 and a position sensor 3. The temperature sensor 2 and the position sensor 3 are linearly connected to the controller and electrically connected to the power supply through the controller. LoRa positioning tags are installed inside the temperature sensor 2 and the position sensor 3. A LoRa gateway is set up between the central control center and each group of equipment. The LoRa positioning tag is independently connected to the LoRa gateway. An auxiliary system is set up on the central control center. Temperature sensor 2, position sensor 3 and LoRa gateway are connected to the auxiliary system through the industrial ring network. The auxiliary system is connected to the computing device through the industrial ring network. Temperature sensor 2, position sensor 3, and the core processing unit of the LoRa gateway are also the core board of Miningcore.

[0023] Temperature sensor 2 and position sensor 3 are fixed to the device body 1 after installation.

[0024] The auxiliary system includes a data receiving module, a big data module, an analysis module, a map module, a positioning module, a network module, and a device communication module, among which; The data receiving module is connected to the temperature sensor and the position sensor to receive temperature data and orientation data transmitted by the temperature sensor and the position sensor. The big data module connects to the big data network to acquire atmospheric temperature information in real time and assists the analysis module in performing analysis. The analysis module is used to combine temperature data, atmospheric temperature information, and azimuth data to analyze and determine equipment operation strategies; The map module is used to build maps on GIS based on existing spatial sites and big data modules; The positioning module is used to display the device's location on a map in real time based on orientation data; The network module provides the network infrastructure for data connections between various components, modules, and devices; The device communication module is connected to the computing device for transmitting data signals to or receiving control data from the computing device.

[0025] The positioning module is also connected to the LoRa gateway and receives location data detected by the LoRa positioning tag transmitted from the LoRa gateway. The orientation data contains two-dimensional point data of the device body, and the location data contains three-dimensional point data of the device body.

[0026] The map module in GIS constructs maps in two dimensions and three dimensions: When the positioning module displays the device itself on the two-dimensional map, the positioning module only displays the location of the device itself on the two-dimensional map based on the location data; When the positioning module displays the device body on the 3D map, it combines location data and orientation data to display the location of the device body on the 3D map.

[0027] The vertical distance between the position sensor and the stability sensor is fixed. The auxiliary system also includes a false detection module. After the positioning module receives the orientation data from the temperature sensor and the position sensor, the false detection module checks the orientation data of the temperature sensor and the position sensor. If the horizontal distance between the two is similar and the vertical distance is similar to the fixed value, the orientation data is correct. If the horizontal distance between the two is not equal, but the vertical distance is similar to the fixed value, the horizontal distance is compared with the position data, and the orientation data with the horizontal distance similar to the position data is selected.

[0028] The auxiliary system also includes a control module, which is connected to the computing device via a device communication module. The control module receives data signals transmitted by the analysis module and the device communication module, and controls the operation of the device itself based on the data signals.

[0029] After receiving the control data, the device communication module transmits the control data to the control module, which then controls the start and stop of the device itself.

[0030] When the analysis module determines the equipment's operating strategy, it also incorporates location data for further judgment. During the judgment process, it uses big data network to assist in the decision-making. Specifically, it combines atmospheric temperature information, orientation data, and location data with big data network data to determine the ambient temperature at the location of the equipment and compares the ambient temperature with the temperature data. If the temperature difference is small, the machine operates according to the original strategy. If the temperature data is higher than the ambient temperature, a strategy of reducing the current and voltage output of the equipment is adopted, and this strategy information is transmitted to the computing device for display through the equipment communication module.

[0031] By adopting the above technical solution, the present invention receives temperature data and orientation data transmitted by temperature sensors and position sensors through a data receiving module, and transmits the temperature data to an analysis module and the orientation data to a positioning module. The analysis module obtains atmospheric temperature information based on a big data module, and analyzes the temperature data, atmospheric temperature information, and orientation data to determine the equipment operation strategy. Based on false detections of orientation data, the analysis module sends alarm information to a computing device through a device communication module. The positioning module marks the specific location of the equipment body on a two-dimensional / three-dimensional map constructed by a map module, combined with the location data and orientation data. The device communication module transmits data signals to the computing device or receives control data transmitted by the computing device. The control module receives data signals transmitted by the analysis module and the device communication module, and controls the operation of the equipment body based on the data signals. Example

The auxiliary system analyzes and locates data using location data, orientation data, temperature data, atmospheric temperature information, two-dimensional maps, and three-dimensional maps. S3. The operator controls the operation of the equipment body and observes the position of the equipment body through the computing device.

[0033] When operators view the location of the equipment itself through the computing device, they can freely switch between two-dimensional and three-dimensional maps.
