[0024] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] According to an embodiment of the present invention, an embodiment of a method for controlling a lighting device on a work surface is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0027] Figure 1 is a flow chart of a method for controlling a lighting device on a work surface according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0028] Step S102, obtaining the position information of the coal mining equipment on the working face of the coal mine.

[0029] In the technical solution provided in the above step S102 of the present invention, the coal mining equipment is used to perform coal mining tasks on the working surface, and may be a coal mining machine. The position information may be position information of the coal mining machine.

[0030] In this embodiment, if there is a need to control the coal mining equipment performing coal mining operations on the working face and the ground control system, the position information of the coal mining equipment on the working face of the coal mine can be obtained.

[0031] Optionally, sensors of various positioning technologies are usually installed on coal mining equipment, including but not limited to Radio Frequency Identification (RFID). In the mine, due to the special limitations of signal propagation, technologies such as RFID, UWB or INS are usually used, which can provide accurate location information in the underground environment. RFID tags are installed on hydraulic supports, and RFID readers are installed on coal mining machines. When the coal mining machine moves, the reader can read the tag information on the supports along the way to determine the real-time location of the coal mining machine.

[0032] Optionally, the location information obtained by the sensors or readers on the coal mining equipment usually needs to undergo certain data processing to ensure its accuracy and availability. For example, the tag information read by the RFID reader may need to go through steps such as decoding and signal strength analysis before it can be converted into the precise location coordinates of the coal mining machine. The processed coal mining machine location information is transmitted to the ground control system in real time through a communication network (such as a visible light communication network, a radio frequency communication network). After receiving this information, the ground control system can integrate and analyze it with other information such as the operating status of the coal mining machine and environmental monitoring data.

[0033] Step S104, determining the lighting devices within the target area around the location information, and enhancing the initial brightness and initial signal strength of the lighting devices to obtain target brightness and target signal strength.

[0034] In the technical solution provided in the above step S104 of the present invention, the lighting device may be a lighting lamp base station, which may include a light emitting diode (LED) lamp.

[0035] In this embodiment, after obtaining the position information of the coal mining equipment on the working surface of the coal mine, the lighting equipment located within the target area around the position information can be determined. The initial brightness and initial signal strength of the lighting equipment can be enhanced to obtain the enhanced target brightness and target signal strength.

[0036] Optionally, a target area can be determined, which is usually the current working area of ​​the coal mining equipment and a certain range nearby, to ensure that the equipment and personnel can get enough lighting and stable data transmission with the ground control center during the coal mining operation. The size and shape of the target area can be flexibly set according to actual work needs and coal mine environmental characteristics, for example, considering the operating width of the coal mining machine, the dust diffusion range, the effective distance of signal transmission and other factors.

[0037] Optionally, adjust the brightness of the lighting equipment (lighting base station): According to the lighting requirements of the target area, the system will enhance the initial brightness of the lighting equipment. For example, when using LED lamps as light sources, the brightness of the LED lamps can be adjusted by controlling the current of the LED driving circuit. In coal mining operations, due to the generation of dust and coal dust, appropriate brightness enhancement helps to improve the visibility of the working face and ensure the safety of miners. Adjust the signal strength of the lighting equipment: In the visible light communication system, the lighting equipment also assumes the function of data transmission. The system will enhance the initial signal strength of the lighting equipment to meet the needs of data transmission. Enhancing the signal strength can be achieved by increasing the luminous power of the LED lamp or using special modulation technology to ensure that the communication quality is not affected by environmental factors (such as dust, gas, etc.).

[0038] Optionally, the brightness and signal strength adjustment of the lighting equipment is usually achieved through the communication between the integrated communication module and the control center. The control center calculates the target brightness and target signal strength based on the location information of the coal mining equipment, and sends adjustment instructions to the lighting equipment in the target area through the communication network. This intelligent control strategy can greatly improve the response speed and flexibility of the system. Energy efficiency optimization: By only enhancing the brightness and signal strength of the lighting equipment in the target area, rather than the equipment on the entire working face, the system can significantly reduce energy consumption and improve energy utilization efficiency. Especially in the mine environment, the rational use of resources is of great significance for reducing operating costs and environmental protection. Enhancing the brightness of lighting equipment can improve the lighting conditions of the working face, reduce the safety hazards caused by insufficient visibility, and improve the working comfort of miners. Stable data transmission: Enhancing the signal strength ensures the stability and reliability of data transmission between the coal mining equipment and the ground control center, which is essential for real-time monitoring of the coal mining operation status, environmental parameters and equipment health. The stability of the communication signal can timely detect and deal with potential equipment failures or environmental risks to ensure production safety.

[0039] In summary, by determining the target area around the coal mining equipment and adjusting the brightness and signal strength of the lighting equipment, the lighting and communication environment of the coal mine working face can be accurately optimized, which not only improves the reliability and security of communication, but also promotes the improvement of production efficiency and the rational use of energy. It is a key component of the modern intelligent coal mine system.

[0040] Step S106, controlling the lighting equipment to emit light according to the target brightness, and sending a signal to the ground control system that communicates with the coal mining equipment according to the target signal strength.

[0041] In the technical solution of step S106 of the present invention, the signal can at least be used to indicate the operating state of the coal mining equipment during the coal mining task, and the environmental conditions around the location information. The ground control system can also be called a control center, a ground control center or a ground control center.

[0042] In this embodiment, after determining the lighting equipment within the target area around the location information and enhancing the initial brightness and initial signal strength of the lighting equipment, the lighting equipment can be controlled to emit light according to the target brightness after the enhancement, and a signal can be sent to a ground control system that communicates with the lighting equipment according to the target signal strength.

[0043] Optionally, the above method is a key execution step for achieving targeted lighting and communication optimization in a coal mine working face communication system based on visible light communication. Through specific operations, it ensures that the working area of ​​the coal mining equipment is properly illuminated and has stable communication, thereby providing key operating status and environmental information to the ground control system.

[0044] Optionally, after determining the lighting equipment within the target area, the system will adjust the luminous intensity of these equipment according to the calculated target brightness value. The above method can accurately adjust the brightness of LED lamps by controlling the current of LED lamps to meet the current operation requirements of coal mining equipment. For example, when a coal mining machine is cutting coal, the increase in dust may affect the line of sight, so the brightness of the lighting equipment in the area will be automatically increased to improve the visibility of the working environment, ensure the safety of miners and improve work efficiency.

[0045] Optionally, the power of the data signal sent by the communication module in the lighting equipment can be adjusted according to the target signal strength. Enhancing the signal strength means increasing the luminous power of the LED lamp to ensure that the communication signal can overcome environmental interference (such as dust and gas) and be stably transmitted to the ground control system. Communication signal content: These signals contain at least the operating status information of the coal mining equipment (such as the health of the equipment, the progress of the operation, etc.) and the environmental conditions around the location information (such as gas concentration, temperature, humidity, dust content, etc.). These data are crucial for the ground control center to monitor the underground working environment in real time, prevent safety accidents, and optimize production scheduling.

[0046] Optionally, after receiving the signal transmitted from the lighting equipment, the ground control system will analyze the operating status and environmental information of the coal mining equipment to determine the safety and efficiency of the current operation, and promptly discover and deal with potential problems. Resource scheduling and equipment control: Based on the real-time location and status information of the coal mining equipment, the ground control center can perform intelligent resource scheduling, such as adjusting the ventilation and power supply systems, or directly controlling the operation of the coal mining equipment to optimize the production process, improve operating efficiency, and ensure the safety of workers. Emergency response and safety warning: In emergency situations, such as equipment failure, gas exceeding the limit, etc., the ground control center can quickly activate the emergency plan and take timely measures, such as evacuating personnel and isolating the accident area, to improve the emergency response speed and reduce accident losses.

[0047] In summary, by controlling the brightness and signal strength of lighting equipment, the lighting and communication quality of the coal mining equipment operation area is ensured, and the ground control center is provided with real-time equipment operation status and environmental information, thereby realizing intelligent monitoring and management of the coal mine working face. This method not only improves the safety and efficiency of coal mine production, but also promotes the intelligent development of mine communication technology, which is an indispensable technical means in modern coal mine operations.

[0048] In the above steps S102 to S106 of the present application, the position information of the coal mining equipment on the working face of the coal mine is obtained, wherein the coal mining equipment is used to perform coal mining tasks on the working face; the lighting equipment within the target area around the position information is determined, and the initial brightness and initial signal strength of the lighting equipment are enhanced to obtain the target brightness and target signal strength; the lighting equipment is controlled to emit light according to the target brightness, and a signal is sent to the ground control system that communicates with the coal mining equipment according to the target signal strength, wherein the signal is at least used to indicate the operating state of the coal mining equipment in the process of performing the coal mining task, and the environmental conditions around the position information. In this embodiment, by intelligently adjusting the brightness and signal strength of the lighting equipment, the surrounding environment of the coal mining equipment is optimized, which not only improves the communication efficiency, but also effectively saves energy, enhances the safety of the working face, and promotes the intelligent and efficient management of coal mine production. This method is an important innovation of modern coal mine communication and lighting systems, and has a significant positive effect on improving the overall efficiency and safety of coal mine operations. Thereby, the technical effect of improving the communication effect between the coal mining equipment and the ground control system is achieved, and the technical problem of poor communication effect between the coal mining equipment and the ground control system is solved.

[0049] The above method of this embodiment is further introduced below.

[0050] As an optional implementation mode, the method is applied to a communication system based on visible light communication, the communication system includes lighting equipment, a radio frequency identification system and a ground control system, the lighting equipment is deployed on the hydraulic support of the working face, step S102, obtaining the position information of the coal mining equipment on the working face of the coal mine, including: in the process of the coal mining equipment performing coal mining operations on the working face, controlling the radio frequency identification system to collect the position information; the method also includes: controlling the radio frequency identification system to send the position information to the ground control system.

[0051] In this embodiment, the method can be applied to a communication system based on visible light communication. The communication system may include lighting equipment, a radio frequency identification system, and a ground identification system. The lighting equipment is deployed on a hydraulic support of a working surface. In the process of obtaining the position information of the coal mining equipment on the working surface, the radio frequency identification system can be controlled to collect the position information during the execution of the coal mining task. And the radio frequency identification system is controlled to send the position information to the ground control system.

[0052] Optionally, the radio frequency identification system plays the role of location information collection in the coal mine communication system. The system mainly includes RFID readers and RFID tags. Among them, the RFID reader is usually installed on coal mining equipment (such as coal mining machines), while the RFID tag is deployed on the hydraulic support of the working face. This design enables the coal mining equipment to automatically read the RFID tag information on the surrounding hydraulic supports while performing the task, so as to determine its specific position in the working face in real time. During the operation of the coal mining equipment, the RFID reader on it will continuously scan and read the RFID tags on the nearby hydraulic supports to collect data containing position codes. The information of the RFID tag is designed to indicate the relative position of the hydraulic support in the working face. When the coal mining equipment passes through these supports, the tag information read by the reader constitutes the real-time position coordinates of the coal mining equipment. This process can be carried out continuously and automatically without human intervention, ensuring the real-time and accuracy of the location information.

[0053] Optionally, the RFID reader on the coal mining equipment sends the acquired location information to the ground control system through a communication network (which can be a radio frequency communication network or a visible light communication network). After receiving this information, the ground control system can update the location and status of the coal mining equipment underground in real time, providing a data basis for subsequent lighting and communication optimization operations. The transmission of this real-time location information is crucial to achieving precise control and resource optimization scheduling, especially in operating scenarios such as coal mines, which have complex environments and high risks.

[0054] As an optional implementation method, the radio frequency identification system includes an radio frequency identification reader and a plurality of radio frequency identification tags. The radio frequency identification reader is deployed at the middle position of the coal mining equipment along the working face direction, and the radio frequency identification tag is deployed at the middle position of the hydraulic support close to the side of the transportation equipment. The transportation equipment is used to perform coal transportation tasks. In the process of the coal mining equipment performing the coal mining task on the working face, the radio frequency identification system is controlled to collect location information, including: in the process of the coal mining equipment performing the coal mining task on the working face, the radio frequency identification reader is controlled to identify the information on the radio frequency identification tag to obtain the location information.

[0055] In this embodiment, the RFID system may include an RFID reader / writer and a plurality of RFID tags. The RFID reader / writer is deployed in the middle of the coal mining equipment along the working direction. The RFID tag is deployed in the middle of the hydraulic support close to the side of the transport equipment. The transport equipment can be used to perform coal transport tasks. In the process of controlling the RFID system to collect location information, the RFID reader / writer can be controlled to identify the information on the RFID tag to obtain the location information.

[0056] Optionally, the radio frequency identification system is closely integrated with the coal mining equipment and hydraulic supports to achieve real-time position tracking of the coal mining equipment in the coal mine working face.

[0057] Optionally, the RFID reader is installed on the coal mining equipment (such as a coal mining machine) and is located in the middle of the equipment along the working face. This deployment method ensures that the reader can cover a sufficiently wide working face area, while reducing the identification blind spots caused by the movement of the equipment, and improving the continuity and integrity of the location information collection. Deployment of RFID tags: The RFID tag is fixed on the hydraulic support, close to the middle position of one side of the transportation equipment (such as a coal truck). The reason for this design is that the movement path of the transportation equipment in the working face is relatively fixed and is usually consistent with the operating direction of the coal mining equipment. This deployment of the tag helps the reader to read the tag information more stably and accurately during the movement of the equipment, and the tag will not be easily blocked or damaged.

[0058] Optionally, during the coal mining operation, the RFID reader on the coal mining equipment will periodically send a wireless RF signal. The frequency of this signal is usually in the UHF band, which can penetrate certain obstacles and non-metallic materials and has good recognition capabilities. After receiving the reader signal, the RFID tag transmits the position encoding information stored on it back to the reader by backscattering. The reader receives and decodes this information, and combines its own timing and movement status to calculate the specific position coordinates of the coal mining equipment on the working face. This process is automatic and continuous, providing real-time position data for the ground control system.

[0059] Optionally, through RFID technology, the system can track the location of coal mining equipment in real time with high accuracy and fast response speed, which is particularly important for coal mines, which require precise control and scheduling. Non-contact information collection: RFID readers can read tag information at a long distance without direct contact, avoiding equipment failure or data loss caused by harsh environmental factors such as coal dust, gas, humidity, etc. Cost-effectiveness and flexibility: Using existing hydraulic supports and coal mining equipment as carriers of the RFID system reduces the construction cost of additional infrastructure. At the same time, the deployment location of RFID readers can be adjusted according to operational needs, which improves the flexibility and adaptability of the system. Safety and efficiency improvement: Real-time location information helps the ground control system accurately monitor the dynamics of underground operations, timely dispatch transportation equipment, adjust ventilation systems, etc., which not only improves production efficiency, but also enhances the safety of mine operations and can quickly respond to emergencies such as equipment failure and personnel positioning.

[0060] Optionally, the location information collected by the RFID system can be combined with the lighting control and data transmission strategies in the visible light communication system, such as steps S104 and S106 described above, to achieve intelligent lighting and data transmission optimization of the environment around the coal mining equipment. This technical integration can further improve the stability and reliability of communication, while optimizing energy use, reducing unnecessary power consumption, and improving mine operation efficiency.

[0061] In summary, the above embodiment realizes the real-time collection and transmission of the position information of the coal mining equipment in the working face by deploying the radio frequency identification system on the coal mining equipment and the hydraulic support, which provides important support for the intelligent management and efficient production of coal mines. The above solution combines the non-contact and high penetration characteristics of RFID with the stability and flexibility of visible light communication.

[0062] As an optional implementation mode, before enhancing the initial brightness and initial signal strength of the lighting device to obtain the target brightness and target signal strength, the method also includes: in response to the ground control system receiving the location information, determining the target area around the location information, and determining a first lighting device set corresponding to the lighting devices within the target area; generating a first control instruction for controlling the first lighting device set; step S104, enhancing the initial brightness and initial signal strength of the lighting device to obtain the target brightness and target signal strength, including: controlling the ground control system to send the first control instruction to each lighting device in the first lighting device set; in response to the lighting device receiving the first control instruction, controlling the lighting device to enhance the initial brightness and initial signal strength to obtain the target brightness and target signal strength.

[0063] In this embodiment, in response to the ground control system receiving the location information, the target area around the location information can be determined. The first lighting device set corresponding to the lighting devices within the target area can be determined, and a first control instruction for controlling the first lighting device set can be generated. The ground control system can be controlled to send the first control instruction to each lighting device in the first lighting device set. When the lighting device receives the first control instruction, the lighting device can be controlled to enhance the initial brightness and the initial signal brightness to obtain the target brightness and the target signal strength.

[0064] Optionally, once the ground control system receives the location information transmitted in real time by the coal mining equipment via the radio frequency identification system (RFID), the system will immediately analyze the data to determine the surrounding environment of the current location of the coal mining equipment. Through algorithm processing, the ground control system can quickly identify the target area around the coal mining equipment, which is usually defined according to actual work needs and environmental characteristics, such as the operating width of the coal mining machine, the possible dust diffusion area, etc.

[0065] Optionally, after the scope of the target area is determined, the ground control system will further identify the lighting equipment within this range, which is the so-called first lighting equipment set. These lighting equipment are usually deployed on hydraulic supports, corresponding to the location of coal mining equipment, and can provide necessary lighting and communication signal support for the working area. Determining the first lighting equipment set is the basis for implementing subsequent control strategies to ensure the optimal allocation and precise application of resources.

[0066] Optionally, the ground control system generates a first control instruction according to current working requirements and environmental conditions. The instruction includes specific parameters for enhancing the brightness and signal strength of the first lighting device set, such as target brightness value, target signal strength, etc. Subsequently, the ground control system sends the first control instruction to each lighting device in the first lighting device set through the communication network. This process reflects the remote control capability of the ground control system over underground equipment and realizes an automated process from data collection to instruction generation.

[0067] Optionally, after the lighting equipment receives the first control instruction sent by the ground control system, they will automatically adjust their brightness and signal strength according to the parameters in the instruction. This adjustment may involve modulating the current of the LED lamp to increase the brightness; or adjusting the transmission power of the communication module to enhance the signal strength. Through enhanced processing, the lighting equipment not only provides more sufficient lighting, but also ensures more stable data communication with the coal mining equipment, reducing the signal attenuation problem caused by environmental factors.

[0068] In the embodiment of the present invention, through the above method, a fully automated process from location information collection to lighting control is realized, which reduces manual intervention and improves the response speed and operating efficiency of the system. Targeted optimization and resource conservation: By only enhancing the lighting equipment in the target area, rather than all equipment in the global range, the system can improve the lighting and communication conditions in the coal mining area in a targeted manner, avoid energy waste, and reduce operating costs. Improved safety and production efficiency: Enhanced lighting and communication conditions help improve the safety and production efficiency of miners, especially when dealing with emergencies, such as equipment failures, environmental abnormalities, etc., which can respond and handle more quickly.

[0069] As an optional implementation mode, the communication system also includes a soot blowing system, which is connected to the lighting equipment and is used to handle dust on the lighting equipment. The soot blowing system includes a main air pipe, and a plurality of branch pipes are installed on the main air pipe. The branch pipes are equipped with a solenoid valve and an air nozzle. The blowing direction of the air nozzle is the same as the wind direction in the working face, and the air nozzle is deployed on the lighting equipment and is located on the side of the air inlet of the working face. The solenoid valve is integrated with a communication module and is connected to the ground control system. The method also includes: in the process of the coal mining equipment performing coal mining operations on the working face, controlling the ground control system to send a third control instruction to the communication module; in response to the communication module receiving the third control instruction, controlling the solenoid valves corresponding to each lighting device in the first lighting device set to open, and controlling the air nozzle to blow air to each lighting device in the first lighting device set to blow away the dust.

[0070] In this embodiment, the communication system may also include a soot blowing system, each soot blowing system is connected to each lighting device one by one, and is used to handle dust on the lighting device. The soot blowing system may include a main air pipe. A plurality of branch pipes are installed on the main air pipe. A solenoid valve and an air nozzle are installed on the branch pipe. The blowing direction of the air nozzle is the same as the wind direction in the working face, and the sealing nozzle is deployed on the lighting device and is located on the side of the air inlet of the working face. A communication module is integrated on the solenoid valve for interconnecting with the ground control system. In the process of the coal mining equipment performing the coal mining operation task, the ground control system can be controlled to send a third control instruction to the communication module, and according to the third control instruction, the solenoid valves on each lighting device in the first lighting device set can be controlled to open, and the air nozzle can be controlled to blow air to the corresponding lighting device to blow away the dust.

[0071] Optionally, in a coal mine working face communication system based on visible light communication, introducing a soot blowing system to handle dust on lighting equipment is an important measure to ensure stable communication quality and extend the service life of the equipment.

[0072] Optionally, the soot blowing system mainly includes components such as a main air pipe, a branch pipe, a solenoid valve and a nozzle. The main air pipe is responsible for providing high-pressure airflow to the branch pipe, and the branch pipe conveys the airflow to the solenoid valve and nozzle on each lighting device. The solenoid valve is used to control the opening and closing of the airflow, and the nozzle is responsible for blowing the airflow to the lighting device in a directional manner to remove dust attached to the device. The blowing direction of the nozzle is designed to be the same as the wind direction of the working face, and is located on the side of the air inlet of the working face of the lighting device. This design can utilize the natural wind flow of the working face to improve the efficiency and effect of soot blowing, and avoid dust diffusion against the wind, which affects the performance of other lighting devices and communication modules. The communication module integrated on the solenoid valve establishes a real-time communication connection with the ground control system. The communication module is responsible for receiving control instructions from the ground control system and converting the instructions into operations on the solenoid valve. This design enables the ground control system to remotely and accurately control the opening and closing time of each solenoid valve, realizing the automation and intelligence of the soot blowing operation.

[0073] Optionally, during the process of the coal mining equipment performing the coal mining operation task, the ground control system will monitor the location information and working status of the coal mining equipment in real time. When it is detected that the coal mining equipment is close to or within the range of the first lighting equipment set, the ground control system will generate and send a third control instruction according to the preset control strategy. This instruction contains the instruction information for opening the solenoid valve within the range of the first lighting equipment set, as well as the parameters of the blowing time and intensity. After the communication module receives the third control instruction sent by the ground control system, it will control the opening of the corresponding solenoid valve so that the airflow blows the lighting equipment in the first lighting equipment set through the wind nozzle. This process effectively removes the dust on the lighting equipment through the impact force of the high-pressure airflow, and restores the normal luminous efficiency and communication signal transmission capability of the equipment. After the soot blowing operation is completed, the solenoid valve will be closed to prevent unnecessary waste of airflow.

[0074] In the embodiment of the present invention, through the intelligent control of the ground control system, the sootblowing system can automatically identify and process the lighting equipment that needs to be cleaned, thereby realizing the automation of the sootblowing operation, reducing the workload of manual maintenance, and improving the intelligence level of the system. Targeted cleaning and resource conservation: Sootblowing is only performed on the equipment within the range of the first lighting equipment set, avoiding indiscriminate cleaning of all lighting equipment, saving airflow resources, and reducing maintenance costs. Communication quality assurance: Removing dust from lighting equipment can reduce the scattering and absorption of visible light communication signals, ensuring the stability and reliability of data transmission, which is crucial for real-time monitoring and management of mine operations. Equipment maintenance and life extension: Regular sootblowing operations help keep lighting equipment clean, reduce equipment failures due to dust accumulation, extend the service life of the equipment, and reduce replacement and repair costs.

[0075] As an optional implementation mode, the method also includes: in response to the ground control system receiving the location information, determining the second lighting device set corresponding to the lighting device outside the target area, and generating a second control instruction to control the second lighting device set; controlling the ground control system to send the second control instruction to each lighting device in the second lighting device set; in response to the lighting device receiving the second control instruction, controlling the brightness and signal strength of the lighting device to be reduced to obtain the reduced brightness and signal strength.

[0076] In this embodiment, if the ground control system receives the location information, it can determine the second lighting device set corresponding to the lighting device outside the target area, and generate a second control instruction for controlling the second lighting device set. The ground control system is controlled to send the second control instruction to each lighting device in the second lighting device set to control the brightness and signal strength of the lighting device to be reduced, thereby obtaining the reduced brightness and signal strength.

[0077] Optionally, in the coal mine working face communication system based on visible light communication, the lighting equipment not only provides the necessary lighting, but also carries the function of data transmission. In order to optimize resource utilization, reduce energy waste and improve communication efficiency, the system adopts a strategy of dynamically adjusting the brightness and signal strength of the lighting equipment.

[0078] Optionally, after the ground control system receives the location information transmitted in real time by the coal mining equipment through the radio frequency identification system (RFID), it will immediately analyze the data to determine the target area where the coal mining equipment is currently located. At the same time, the system will also identify the lighting equipment outside this area, that is, the second lighting equipment set. This ability to dynamically divide areas is the basis for achieving refined resource management.

[0079] Optionally, based on the division of lighting equipment inside and outside the target area, the ground control system generates a second control instruction. This instruction includes specific parameters for reducing the brightness and signal strength of the second lighting equipment set, such as a target brightness reduction value, a target signal strength reduction value, etc. The setting of these parameters is usually based on the real-time environmental conditions, communication requirements and energy management strategies of the coal mine working face.

[0080] Optionally, the ground control system sends the second control instruction to each lighting device in the second lighting device set through a communication network between the ground control system and the lighting device. The communication network may use radio frequency communication or other reliable communication methods to ensure that the instruction can be delivered to the target device in a timely and accurate manner. This remote instruction sending mechanism reflects the intelligent control capability of the ground control system over the underground equipment.

[0081] Optionally, after the lighting devices receive the second control instruction, they will automatically adjust their brightness and signal strength according to the parameters in the instruction to achieve the reduction process. In the visible light communication system, reducing the brightness may involve reducing the current input of the LED lamp, while reducing the signal strength may be achieved by adjusting the transmission power of the communication module. By reducing the process, the system can reduce energy consumption in non-operating areas, while avoiding excessive occupation of spectrum resources by signals, and optimizing the efficiency of the entire communication network.

[0082] In an embodiment of the present invention, by dynamically adjusting the brightness and signal strength of lighting equipment, the system can significantly reduce energy consumption in non-target areas, reduce overall operating costs, and reflect efficient use of resources. Communication network optimization: Reducing the signal strength of lighting equipment outside the target area helps to reduce interference in the communication network and improve the efficiency and reliability of data transmission within the entire system. Intelligent mine management: The above steps demonstrate the ability of the ground control system to intelligently manage underground equipment. It can automatically adjust the status of equipment according to the real-time environment and operating requirements, and is one of the key technologies for realizing intelligent management of modern mines. Safety and operating efficiency: Optimized lighting and communication conditions help improve the safety and operating efficiency of miners, especially when dealing with emergencies, such as equipment failures and environmental abnormalities, and can respond more quickly to improve the safety of mine operations.

[0083] As an optional embodiment, the communication system also includes a lighting power supply, which is connected to the lighting equipment and is used to provide power to the lighting equipment. The lighting equipment is provided with an emergency power supply. The method also includes: in the process of the lighting power supply providing visible light lighting to the coal mining equipment, controlling the lighting power supply to detect the power status of the emergency power supply; in response to the power status being lower than a power status threshold, controlling the lighting power supply to charge the emergency power supply.

[0084] In this embodiment, the communication system also includes a lighting power supply, which is connected to the lighting equipment and is used to provide power to the lighting equipment. The lighting equipment is provided with an emergency power supply. In the process of the lighting power supply providing visible light illumination to the coal mining equipment, the lighting power supply can be controlled to detect the power state of the emergency power supply. When the power state is lower than the power state threshold, the lighting power supply can be controlled to charge the emergency power supply.

[0085] Optionally, in a coal mine working face communication system based on visible light communication (VLC), it is crucial to ensure the continuous operation of lighting equipment and its communication functions, especially in emergency situations.

[0086] Optionally, the lighting power supply is the component in the entire system responsible for powering the lighting equipment. It is connected to the lighting equipment through wires or wireless charging technology to ensure that the lighting equipment can continuously provide lighting and communication functions. The lighting power supply may be a fixed power supply unit, such as ground power facilities, or a mobile power supply system integrated in the mine, such as lighting comprehensive protection. In order to cope with possible power outages or other unexpected situations, each lighting device is equipped with an emergency power supply. The emergency power supply is usually a built-in battery or rechargeable power supply, which can automatically switch to the emergency power supply when the lighting power supply fails to ensure the normal operation of lighting and communication functions. The selection and design of the emergency power supply must take into account the special working environment of the mine, such as explosion-proof, long life, fast charging and other characteristics.

[0087] Optionally, when the lighting power supply is operating normally, the system will continuously monitor the power status of the emergency power supply. This process can be performed by the built-in monitoring system of the lighting power supply, or remotely monitored by the ground control system through the communication network. Monitoring the power status is a key step to ensure that the emergency power supply is available when needed. When it is detected that the power status of the emergency power supply is lower than the preset power status threshold, the system will automatically trigger the charging process. This control can be achieved through the intelligent charging management function of the lighting power supply, that is, the power of the lighting power supply is used to charge the emergency power supply while ensuring the normal operation of the lighting equipment. The triggering and stopping of the charging process are automatically determined by the algorithm of the lighting power supply or the ground control system to ensure that the emergency power supply is always maintained at a suitable power status without affecting daily operations.

[0088] In the embodiment of the present invention, an emergency power supply is provided and power status detection and intelligent charging are implemented, which significantly improves the reliability of the communication system in emergency situations and reduces the risk of communication interruption due to power failures, thereby enhancing the safety of coal mine work. Optimal resource utilization: Intelligent charging management can dynamically adjust the charging strategy according to the power status of the emergency power supply, avoid overcharging or undercharging, and improve the efficiency of energy use. Simplified maintenance and management: The entire charging process is automatically monitored and controlled by the system, reducing the need for manual intervention, simplifying the maintenance and management of the equipment, and reducing operating costs. Continuity and flexibility: The configuration of the emergency power supply provides a guarantee for the continuous operation of the system. At the same time, the flexibility of the intelligent charging mechanism adapts to the variability and unpredictability of mine operations.

[0089] In summary, the above steps describe the collaborative working mechanism of the lighting power supply and the emergency power supply in the coal mine working face communication system based on visible light communication. By continuously detecting the power status and intelligent charging control, it ensures that the lighting equipment can continue to provide lighting and communication services even in the event of power outages. It is an important part of the intelligent and automated communication system of the mine.

[0090] In an embodiment of the present invention, the position information of the coal mining equipment on the working face of the coal mine is obtained, wherein the coal mining equipment is used to perform coal mining tasks on the working face; the lighting equipment located within the target area around the position information is determined, and the initial brightness and initial signal strength of the lighting equipment are enhanced to obtain the target brightness and target signal strength; the lighting equipment is controlled to emit light according to the target brightness, and a signal is sent to the ground control system that communicates with the coal mining equipment according to the target signal strength, wherein the signal is at least used to indicate the operating state of the coal mining equipment in the process of performing the coal mining task, and the environmental conditions around the position information. In this embodiment, by intelligently adjusting the brightness and signal strength of the lighting equipment, the surrounding environment of the coal mining equipment is optimized, which not only improves the communication efficiency, but also effectively saves energy, enhances the safety of the working face, and promotes the intelligent and efficient management of coal mine production. This method is an important innovation of modern coal mine communication and lighting systems, and has a significant positive effect on improving the overall efficiency and safety of coal mine operations. Thereby, the technical effect of improving the communication effect between the coal mining equipment and the ground control system is achieved, and the technical problem of poor communication effect between the coal mining equipment and the ground control system is solved.

[0091] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0092] At present, in modern mining, with the development of science and technology and the increase in production safety requirements, traditional mine communication methods can no longer meet the needs of efficient and safe mining operations. Traditional radio frequency communication technology is limited by environmental factors such as high gas and dust in coal mines, is susceptible to interference, and has uneven signal coverage. Therefore, it is particularly urgent to develop a new, stable and reliable mine communication system.

[0093] The embodiment of the present invention proposes a coal mine working face communication system based on visible light communication. The visible light communication technology has several significant advantages. First, the spectrum resources are rich, using the visible light band of 380-780nm; second, the cost is low. Based on the current LED lighting facilities, the communication function can be realized at a low cost; third, it is green and environmentally friendly. Compared with radio frequency communication, visible light communication hardly generates electromagnetic interference and is environmentally friendly; it also does not generate electric sparks, and is applied in high-gas mines with high reliability and safety. Combined with modern lighting technology, VLC is integrated into the mine lighting system, which not only provides continuous lighting but also realizes efficient data transmission, providing a new idea for communication under the mine. In addition, by integrating radio frequency identification technology, the positioning and management of mobile devices such as coal mining machines can be realized, further enhancing the practicality and safety of the system. Thereby, the technical effect of improving the communication effect between coal mining equipment and ground control system is achieved, and the technical problem of poor communication effect between coal mining equipment and ground control system is solved.

[0094] The embodiments of the present invention are further described below.

[0095] In an embodiment of the present invention, in order to overcome the defects of the prior art, the present invention provides a coal mine working face communication system based on visible light communication, which is not affected by electromagnetic interference and ensures the stability and reliability of data transmission.

[0096] In this embodiment, in order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a coal mine working face communication system based on visible light communication, including: a lighting power supply, multiple lighting base stations and a control center, characterized in that multiple lighting base stations are arranged on the bracket of the coal mining working face, the lighting base stations are used for working face lighting, and multiple lighting base stations are connected to the communication network. Communication modules are integrated in the lighting base stations and the working face coal mining machines for sending and receiving data. It also includes a radio frequency identification system for identifying the position of the coal mining machine and sending the position data to the control center, so that the control center can grasp the position of the coal mining machine in real time. The control center controls the three lighting base stations closest to the coal mining machine through the communication network to increase the brightness and signal strength, and the remaining lighting base stations reduce the brightness and signal strength.

[0097] Optionally, the RFID system includes an RFID reader and multiple RFID tags, the RFID reader is arranged in the middle position of the coal mining machine along the working face direction, and the RFID tag is arranged in the middle position of the hydraulic support close to the conveyor side.

[0098] Optionally, no RFID tags are installed on the first two frames and the rear two frames of the hydraulic support, and the RFID reader / writer identifies the RFID tags installed on the hydraulic support and sends the collected data to the control center.

[0099] Optionally, the lighting power supply is a lighting comprehensive protection, which is connected to multiple lighting lamp base stations. At the same time, each lighting lamp base station is provided with an emergency power supply, which is a rechargeable power supply. The lighting comprehensive protection has an intelligent charging management function, which can automatically adjust the charging mode according to the power status of the emergency power supply. The lighting comprehensive protection can charge the emergency power supply.

[0100] Optionally, a soot blowing system is also included, which is used to blow away dust on the lighting lamp base station. The soot blowing system includes a main air pipe, multiple branch pipes are installed on the main air pipe, and solenoid valves and air nozzles are installed on the branch pipes. The blowing direction of the air nozzle is consistent with the wind direction of the working surface, and the air nozzle is located on the side of the air inlet of the working surface of the lighting lamp base station.

[0101] Optionally, multiple solenoid valves are integrated with communication modules and can communicate with the control center. The control center is connected to the radio frequency identification system, so that the control center can open the solenoid valves on the three lighting base stations closest to the coal mining machine according to the specific location of the coal mining machine, so that high-pressure wind can blow away the dust on the three lighting base stations that increase the brightness, and the remaining solenoid valves are in a closed state.

[0102] Compared with the prior art, the present invention has the following beneficial effects: (1) Visible light communication is not affected by electromagnetic interference, thus ensuring the stability and reliability of data transmission, especially in coal mine environments with severe electromagnetic interference; the control center can grasp the underground situation in real time, facilitate rapid decision-making and resource allocation, and improve the management efficiency and production efficiency of the mine; (2) By increasing the brightness and signal strength of the lighting base station close to the coal mining machine, the scattering effect of a large amount of dust generated during the coal cutting process on the light can be effectively counteracted, thereby maintaining the stability and reliability of communication; reducing the brightness and signal strength of the lighting base station far away from the coal mining machine area helps to save energy and reduce unnecessary power consumption; (3) By setting up an emergency power supply on each lighting base station and ensuring that these power supplies can be used in the event of a power outage Independent power supply is provided in the event of an emergency, which significantly improves the overall reliability of the system and reduces the risk of communication interruption due to power supply problems. The lighting comprehensive protection has an intelligent charging management function, which can automatically adjust the charging mode according to the power status of the emergency power supply, which helps to protect the battery life and prevent overcharging, while ensuring that the emergency power supply is always in a suitable power state. (4) By effectively blowing away the dust on the lighting base station, the dust reduces the obstruction of light, thereby maintaining the stability of the signal strength and ensuring that the communication quality is not affected. Combined with the design of the solenoid valve and the air nozzle, the soot blowing operation can be automatically controlled, reducing manual intervention and improving the intelligence level of the system. The soot blowing system combines the particularity of the coal mine working environment and improves the soot blowing effect by blowing in a direction consistent with the wind direction of the working face.

[0103] Figure 2 A schematic diagram of a coal mine working face communication system based on visible light communication provided by the present invention is shown in FIG. Figure 2As shown, the coal mine working face communication system based on visible light communication provided by the present invention includes: lighting power supply, multiple lighting base stations and control center, multiple lighting base stations are arranged on the bracket of the coal mining working face, the lighting base stations are used for working face lighting, the lighting base stations use LED lights, multiple lighting base stations are connected to the communication network, and the lighting base stations and the working face coal mining machine are integrated with communication modules for sending and receiving data, and the equipment operation status, environmental monitoring data, video monitoring data and alarm and fault information of the coal mining machine are transmitted to the ground control center, and the ground control center can grasp the data and equipment operation status of the coal mining machine in real time. The above scheme monitors the equipment operation status and environmental monitoring data of the coal mining machine in real time, can timely discover and deal with potential safety hazards, and reduce the accident rate; visible light communication is not affected by electromagnetic interference, which ensures the stability and reliability of data transmission, especially in the coal mine environment with severe electromagnetic interference; LED lamps are more energy-efficient than traditional lighting equipment, and the integration of communication modules reduces the investment in additional communication equipment and reduces operating costs; the control center can grasp the underground situation in real time, which is convenient for rapid decision-making and resource allocation, and improves the management efficiency and production efficiency of the mine.

[0104] Optionally, the radio frequency identification system is used to identify the location of the coal mining machine and send the location data to the control center, so that the control center can grasp the location of the coal mining machine in real time. Since the control center knows the location of the coal mining machine, it can control the three lighting base stations closest to the coal mining machine through the communication network to increase the brightness and signal strength. At the same time, the remaining lighting base stations reduce the brightness and signal strength. The reason for doing this is that when the coal mining machine is cutting coal, the dust content in the air will greatly increase. These dusts scatter the light, thereby reducing the signal strength. Increasing the brightness of the lighting base station can increase the signal strength, thereby ensuring normal communication between the coal mining machine and the lighting base station. At the same time, the lighting intensity and signal of other lighting base stations are weakened.

[0105] Optionally, by increasing the brightness and signal strength of the lighting base station close to the coal mining machine, the scattering effect of the large amount of dust generated during the coal cutting process on the light can be effectively counteracted, thereby maintaining the stability and reliability of communication; reducing the brightness and signal strength of the lighting base station far away from the coal mining machine area helps to save energy and reduce unnecessary electricity consumption; the control center automatically adjusts the lighting configuration according to the real-time position of the coal mining machine, thereby improving the automation and intelligence level of the coal mine working face and reducing the need for manual intervention; optimized lighting conditions not only help to improve the line of sight of the working face, but also ensure the stability of the communication signal, thereby improving the efficiency and safety of coal mining operations.

[0106] The RFID system includes an RFID reader and multiple RFID tags. The RFID reader is set in the middle of the coal mining machine along the working face, and the RFID tag is set in the middle of the hydraulic support near the conveyor. By installing an RFID reader on the coal mining machine and setting an RFID tag on the hydraulic support, the system can monitor the specific position of the coal mining machine in real time to ensure the accuracy of various operations.

[0107] The first two and the last two hydraulic supports are not equipped with RFID tags, that is, the number of RFID tags is four less than the number of hydraulic supports, because these four supports are located at the head or tail of the working face, and the coal mining machine cannot run to these two places. However, when cutting coal, the left and right coal cutting rollers can reach these positions to cut coal. During the movement of the coal mining machine, the coal mining machine drives the RFID reader to move and identify the RFID tags installed on the hydraulic supports, collect signals and send the collected data to the control center. By reducing the number of RFID tags, the cost of the system can be reduced to a certain extent.

[0108] Figure 3 The schematic diagram of the emergency power supply arrangement in the coal mine working face communication system based on visible light communication provided by the present invention is as follows: Figure 3 As shown, the lighting power supply is a lighting comprehensive protection, which is connected to multiple lighting base stations. At the same time, each lighting base station is equipped with an emergency power supply. The emergency power supply is a rechargeable power supply. The lighting comprehensive protection has an intelligent charging management function and can automatically adjust the charging mode according to the power status of the emergency power supply. When it is detected that the power of the emergency power supply is lower than the set threshold, the lighting comprehensive protection will start the charging process and automatically stop after the power is fully charged to protect the battery life and avoid overcharging. Under normal circumstances, the lighting comprehensive protection can charge the emergency power supply. When the emergency power supply is fully charged, the charging stops. Once the wire between the lighting comprehensive protection and the lighting base station or between the lighting base station and the lighting base station is disconnected, the emergency power supply will supply power to the lighting base station so that the lighting base station can work normally. At the three-shift site, the emergency battery should be able to ensure that the lighting base station works for 8 hours, and at the two-shift site, the emergency battery should be able to ensure that the lighting base station works for 12 hours, ensuring that even in the case of a long-term power outage, the lighting and communication of the working face will not be interrupted, ensuring the safety of the miners and the continuity of production.

[0109] Optionally, by setting up emergency power supplies on each lighting base station and ensuring that these power supplies can independently supply power in the event of a power outage, the overall reliability of the system is significantly improved, reducing the risk of communication interruption due to power supply problems; the lighting comprehensive protection has an intelligent charging management function, which can automatically adjust the charging mode according to the power status of the emergency power supply, which helps to protect the battery life and prevent overcharging, while ensuring that the emergency power supply is always in an appropriate power state; in emergency situations, such as long-term power outages, the emergency power supply can ensure the normal operation of the lighting base station and provide the necessary lighting and communication support for the miners, thereby ensuring the safety of the miners.

[0110] Figure 4 A schematic diagram of a soot blowing system in a coal mine working face communication system based on visible light communication provided by the present invention, such as Figure 4 As shown, it also includes a soot blowing system, which is used to blow away dust on the lighting lamp base station to avoid dust blocking the light and thereby weakening the signal strength. The soot blowing system includes a main air pipe, and a plurality of branch pipes are installed on the main air pipe. The branch pipes are equipped with solenoid valves and air nozzles. The blowing direction of the air nozzle is consistent with the wind direction of the working surface, and the air nozzle is located on the side of the air inlet of the working surface of the lighting lamp base station. This can achieve a better soot blowing effect, because the dust on the working surface moves along the fresh wind of the working surface. For this reason, more dust will adhere to the direction in which the fresh wind enters the lighting lamp base station.

[0111] Optionally, by effectively blowing away the dust on the lighting base station, the dust's obstruction to light is reduced, thereby maintaining the stability of the signal strength and ensuring that the communication quality is not affected; combined with the design of the solenoid valve and the air nozzle, the soot blowing operation can be automatically controlled, reducing manual intervention and improving the intelligence level of the system; the soot blowing system combines the particularity of the coal mine working environment and improves the soot blowing effect by blowing in a direction consistent with the wind direction of the working face.

[0112] Optionally, multiple solenoid valves are integrated with communication modules and can communicate with the control center. Since the control center is connected to the radio frequency identification system, the control center can open the solenoid valves on the three lighting base stations closest to the coal mining machine according to the specific location of the coal mining machine, so that high-pressure wind can blow away the dust on the three lighting base stations that increase the brightness, thereby preventing dust from blocking the light of the lighting base stations and weakening the network strength. The remaining solenoid valves are all in a closed state. When the coal mining machine continues to move, the control center will open and close the corresponding solenoid valves according to the actual position of the coal mining machine, which can achieve accurate dust blowing, save compressed air, and reduce energy consumption.

[0113] Optionally, by accurately blowing away dust on the lighting base station near the coal mining machine, dust blocking the light is avoided, thereby maintaining the strength of the communication signal and the stability of the lighting effect; by intelligently controlling the opening and closing of specific solenoid valves, unnecessary compressed air consumption is reduced, thereby reducing energy consumption; the control center can automatically adjust the working state of the solenoid valve according to the real-time position of the coal mining machine, thereby improving the level of intelligence in coal mine working face management.

[0114] In an embodiment of the present invention, the position information of the coal mining equipment on the working face of the coal mine is obtained, wherein the coal mining equipment is used to perform coal mining tasks on the working face; the lighting equipment located within the target area around the position information is determined, and the initial brightness and initial signal strength of the lighting equipment are enhanced to obtain the target brightness and target signal strength; the lighting equipment is controlled to emit light according to the target brightness, and a signal is sent to the ground control system that communicates with the coal mining equipment according to the target signal strength, wherein the signal is at least used to indicate the operating state of the coal mining equipment in the process of performing the coal mining task, and the environmental conditions around the position information. In this embodiment, by intelligently adjusting the brightness and signal strength of the lighting equipment, the surrounding environment of the coal mining equipment is optimized, which not only improves the communication efficiency, but also effectively saves energy, enhances the safety of the working face, and promotes the intelligent and efficient management of coal mine production. This method is an important innovation of modern coal mine communication and lighting systems, and has a significant positive effect on improving the overall efficiency and safety of coal mine operations. Thereby, the technical effect of improving the communication effect between the coal mining equipment and the ground control system is achieved, and the technical problem of poor communication effect between the coal mining equipment and the ground control system is solved.

[0115] According to an embodiment of the present invention, a control device for a lighting device on a work surface is also provided. It should be noted that the control device for a lighting device on a work surface can be used to execute the control method for a lighting device on a work surface in the above embodiment.

Figure 5 As shown, the control device 500 for the lighting equipment on the work surface may include: an acquisition unit 502 , a processing unit 504 , and a control unit 506 .

[0117] The acquisition unit 502 is used to acquire the position information of the coal mining equipment on the working face of the coal mine, wherein the coal mining equipment is used to perform coal mining tasks on the working face.

[0118] The processing unit 504 is used to determine the lighting devices located within the target area around the location information, and enhance the initial brightness and initial signal strength of the lighting devices to obtain target brightness and target signal strength.
