[0049] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0050] A perfect communication system is essential to ensure the safety of mine technicians and improve the efficiency of emergency rescue. Currently, there are usually two communication methods used in mine communication systems. First, branch Ethernet: FDDI is used as the backbone network and traditional Ethernet is used as the branch. The two are combined to form the entire communication network system. At the same time, switching technology is used to solve the interface conversion problem between FDDI and unified Ethernet, and provide a high-speed trunk channel. Second, industrial field bus: connect field equipment and control systems using CAN, DeviceNet and other methods to form a fully digital, two-way, multi-variable communication network.

[0051] However, in mining environments, due to complex terrain, narrow space, and harsh environment, traditional wired communication systems face problems such as difficult deployment, high costs, and complex maintenance.

[0052] For example, the environment inside a mine is usually very complex, including narrow passages, steep slopes, criss-crossing tunnels, etc. These factors make the deployment of wired communication systems extremely difficult, as a large number of cables and lines need to be laid, which is not only costly but also vulnerable to disasters such as mine accidents.

[0053] In addition, the working conditions inside mines are usually very harsh, including high temperature, high humidity, dust, harmful gases, etc. These conditions put forward higher requirements on the stability and reliability of communication equipment, and wired communication systems are often difficult to adapt to such environments.

[0054] In addition, the deployment of wired communication systems inside mines requires a large number of cables and equipment, which leads to high deployment costs. At the same time, due to the particularity of the mining environment, the maintenance and repair of wired communication systems is also very difficult, further increasing maintenance costs.

[0055] Also, because the working environment and requirements of mines change frequently, a flexible and scalable communication system is needed to adapt to these changes. However, wired communication systems are often difficult to quickly adapt to these changes due to their fixed physical structure.

[0056] Based on the above questions, please refer to Figure 1An embodiment of the present application provides an underground mine communication system, which includes a ground communication terminal, an underground communication terminal, a first mobile terminal and a second mobile terminal. The first mobile terminal is configured to communicate directly with the underground communication terminal, and the second mobile terminal is configured to communicate with the first mobile terminal based on a preset data sharing technology.

[0057] The second mobile terminal can send the collected second device message to the first mobile terminal based on a preset data sharing technology;

[0058] The first mobile terminal can send the collected first device message and the received second device message to the underground communication terminal;

[0059] The underground communication terminal can send the collected current environment information, the received first device message and the received second device message to the ground communication terminal.

[0060] Specifically, the ground communication terminal refers to the communication equipment located on the ground. As part of the communication network, it is responsible for communicating with the underground communication terminal or other ground equipment. The ground communication terminal receives various types of information sent from the underground communication terminal, such as environmental monitoring data, equipment status, location and health information of the staff, etc. The ground communication terminal processes and analyzes the received information so that the ground management personnel can better understand the conditions inside the mine and make corresponding decisions. The ground communication terminal also has a data storage function, which can record and store communication history data for subsequent analysis and auditing. The ground communication terminal also has the ability to connect to external networks (such as the Internet, dedicated networks, etc.), so that the communication system inside the mine can exchange information with external rescue agencies, management centers, etc.

[0061] The underground communication terminal refers to the key component in the underground mine communication system. It is located inside the mine and is responsible for collecting, processing and transmitting information and data in the mine. There are multiple underground communication terminals inside the mine, distributed in different locations. The underground communication terminal is equipped with a data acquisition module, which can monitor the environmental parameters in the mine in real time, such as temperature, humidity, smoke concentration, gas composition, etc. It can also receive information sent from various devices inside the mine (such as sensors, mobile terminals, etc.) and perform preliminary processing. This information may include the working status of the equipment, the health and safety status of the staff, etc.

[0062] Mobile terminals refer to communication devices that users can carry with them, which provide a flexible and convenient way of communication for workers in the mine. Mobile terminals support multiple communication methods such as voice, text, and video, allowing workers to exchange information and communicate in real time inside the mine. In addition, the mobile terminal is equipped with sensors for collecting the location information, health status, or data of the surrounding environment of the staff, and transmitting these data to the underground communication terminal or the ground communication terminal. In case of emergency, the staff can use the mobile terminal to send a distress signal and receive emergency responses and guidance from the ground communication terminal at the same time. Mobile terminals are usually equipped with a display screen that can display maps, work instructions, safety information, etc., to help workers better understand the situation inside the mine and their own location. Mobile terminals can be connected through preset data sharing technology to achieve information sharing and collaboration, and improve work efficiency and teamwork ability. In the implementation mode of the present application, a general Android thousand-yuan smartphone that can realize Wi-Fi information reception and Wi-Fi sharing between smartphones is used as a mobile terminal.

[0063] The preset data sharing technology refers to a series of technologies that can be used in the underground mine communication system to achieve data exchange and sharing between mobile terminals, including Wi-Fi, Bluetooth, ZigBee, RFID, etc. In some embodiments, the preset data sharing technology includes data encryption and security authentication measures to prevent unauthorized access and data leakage.

[0064] The second device message refers to information collected and sent by the second mobile terminal.

[0065] The first device message refers to information collected and sent by the first mobile terminal.

[0066] The second mobile terminal does not communicate directly with the underground communication terminal, but sends and receives the collected second device messages through the first mobile terminal as a relay, and sends the collected second device messages to the first mobile terminal based on the preset data sharing technology.

[0067] The first mobile terminal directly establishes a communication connection with the underground communication terminal. In addition to collecting environmental information and device status around itself, the first mobile terminal is also responsible for receiving data from the second mobile terminal and sending all the information to the underground communication terminal after aggregation. A first mobile terminal can establish a communication connection with multiple second mobile terminals.

[0068] The underground communication terminal sends all received information, including environmental data, equipment status, and possible location information of other miners, to the ground communication terminal.

[0069] In summary, the present application provides an underground mine communication system. The underground mine communication system includes a ground communication terminal, an underground communication terminal, a first mobile terminal and a second mobile terminal. The first mobile terminal can be directly connected to the underground communication terminal, and the second mobile terminal can be connected to the first mobile terminal based on a preset data sharing technology. The second mobile terminal can send the collected second device message to the first mobile terminal based on the preset data sharing technology. The first mobile terminal can send the collected first device message and the received second device message to the underground communication terminal. The underground communication terminal can send the collected current environment information, the received first device message and the received second device message to the ground communication terminal. In this way, by configuring the direct connection between the first mobile terminal and the underground communication terminal, and making the second mobile terminal indirectly connected through the first mobile terminal, the system achieves a wider communication coverage. Even in the complex environment of the underground mine, this multi-level communication network can ensure reliable data transmission. In addition, by using existing power lines and wireless communication technologies, the cost of establishing a separate communication link for each device is avoided.

[0070] In some embodiments, the second device message includes operation monitoring information and / or communication information of the second mobile terminal, and the first device message includes operation monitoring information and / or communication information of the first mobile terminal, the operation monitoring information includes location information, operation information and / or security information, and the communication information includes text information, voice information and / or video information.

[0071] Specifically, location information refers to providing the specific location of the mobile terminal, which is crucial for navigation, personnel positioning and emergency rescue in mines.

[0072] Operational information refers to the operational status of the mobile terminal, such as whether the device is working properly, which is very important for monitoring device health and formulating maintenance plans.

[0073] Safeguard information refers to equipment maintenance records, safety inspection results, etc., which helps ensure safe operation and timely maintenance of equipment.

[0074] Text messaging refers to the use of text messaging, such as work instructions, safety warnings, etc. It is a quick way to transmit important information in daily communication and emergency situations.

[0075] Voice messaging refers to allowing miners to communicate via voice, providing instant communication and feedback, which is very important for quick decision-making and conveying instructions in emergency situations.

[0076] Video information refers to the provision of real-time video streams, which enables ground personnel to intuitively understand the situation inside the mine, which is very useful for safety monitoring and accident investigation.

[0077] In this way, the integration and transmission of this information, through the collaboration between the first mobile terminal and the second mobile terminal, and the connection with the underground communication terminal and the ground communication terminal, ensures the comprehensiveness and efficiency of the internal communication of the underground mine. Through this communication system, mine managers can monitor the environment and equipment status inside the mine in real time and respond to various situations in a timely manner, thereby improving the safety and work efficiency of the mine.

[0078] Please refer to Figure 1 In some embodiments, the first mobile terminal can:

[0079] Based on the first preset filtering rule, the second device message and the first device message are filtered to generate a third device message.

[0080] Specifically, the first preset filtering rule refers to a set of pre-set rules for the first mobile terminal to filter and process the message content according to these rules when processing and forwarding the first device message and the second device message, which can optimize the data flow and ensure that the transmitted information is relevant and important, thereby improving communication efficiency and reducing unnecessary bandwidth usage. First, filter according to the type of message (such as operation monitoring information, communication information, environmental monitoring data, security alarms, etc.), and only forward messages of specific types. Second, for environmental monitoring data, etc., a threshold can be set, and the data is only forwarded when it exceeds or falls below the preset threshold to highlight abnormal situations. Third, filter according to the timestamp of the message, for example, only forward messages within the recent period of time to maintain the timeliness of the information. Fourth, set priorities according to the urgency or importance of the message to ensure that high-priority messages can be processed and forwarded first. Fifth, compress and simplify the message content, remove unnecessary information, and reduce the amount of data transmission.

[0081] Thus, through this filtering process, the first mobile terminal can effectively manage the information flow, ensuring that only the most critical and relevant information is transmitted to the underground communication terminal and the ground communication terminal. This not only improves the communication efficiency, but also reduces the burden of information processing, allowing ground management personnel to make decisions more quickly and accurately. At the same time, this also helps to reduce the occupation of communication bandwidth and reduce the overall complexity and cost of the system.

[0082] See also Figure 2 In some embodiments, the underground mine communication system further includes an information conversion device capable of:

[0083] Receiving a third device message sent by the first mobile terminal;

[0084] Based on a preset information conversion protocol, convert the third device message to obtain a fourth device message;

[0085] Based on the power line carrier communication technology, a fourth device message is sent to the underground communication terminal.

[0086] Specifically, the information conversion device is a key component, which is responsible for converting the third device message sent by the first mobile terminal into a fourth device message that can be received and processed by the underground communication terminal. The information conversion device can handle the conversion between different communication protocols to ensure that the message from the first mobile terminal can be correctly understood and received by the underground communication terminal. For example, if the first mobile terminal uses a wireless communication protocol and the underground communication terminal uses a wired communication protocol, the information conversion device needs to convert between the two. An information conversion device can only be connected to one first mobile terminal at the same time. In some embodiments, the information conversion device can also provide encryption and decryption functions to ensure data security during transmission.

[0087] The preset information conversion protocol refers to a set of predefined rules and standards for converting the third device message sent by the first mobile terminal into a fourth device message that can be received and processed by the underground communication terminal, ensuring that different devices can communicate effectively even under different communication technologies and protocols. Since the first mobile terminal and the underground communication terminal use different communication protocols, protocol conversion is required to ensure that the message can be transmitted correctly.

[0088] The underground mine communication system also includes an information conversion device, which can receive a third device message sent by the first mobile terminal. Then, based on a preset information conversion protocol, the third device message is converted and processed to obtain a fourth device message. Finally, based on the power line carrier communication technology, the fourth device message is sent to the underground communication terminal.

[0089] In this way, through the integrated information conversion equipment, the underground mine communication system realizes the seamless connection between wireless communication and power line carrier communication, ensuring effective communication inside and outside the mine, thereby improving the flexibility and reliability of the communication system, while also reducing costs, making mine communication more efficient and economical.

[0090] See also Figure 3 ,The underground communication terminal includes a data acquisition module;

[0091] The underground communication terminal can collect current environmental information through the data collection module, and the current environmental information includes the temperature, humidity and / or smoke level of the environment.

[0092] Specifically, current environmental information refers to real-time data of the internal environment of the mine, which is collected by the underground communication terminal through its data acquisition module. Current environmental information is essential to ensure mine safety, monitor potential hazards and improve work efficiency.

[0093] The temperature inside a mine can have an impact on the health of workers and the operation of equipment. Monitoring the temperature helps maintain a suitable working environment.

[0094] Humidity that is too high or too low can cause equipment failure or affect the health of workers.

[0095] Smoke may be a sign of fire or other danger. Real-time monitoring of smoke levels helps to detect and respond to potential safety threats in a timely manner. In some embodiments, the current environmental information also includes harmful gases, dust, air pressure changes, vibrations, noise, etc.

[0096] Harmful gases such as methane, carbon monoxide, etc. may exist in mines. Monitoring gas concentrations is essential to prevent poisoning and explosion accidents.

[0097] Dust in mines can cause respiratory problems. Monitoring dust concentrations helps protect the health of workers.

[0098] Changes in air pressure inside a mine can affect worker comfort and equipment performance.

[0099] Wind speed and direction are critical to the design and optimization of ventilation systems, and also affect the speed and direction of fire spread.

[0100] High levels of vibration and noise can cause hearing damage to workers and affect the normal operation of equipment.

[0101] In this way, by collecting environmental information in real time or periodically, underground communication terminals can obtain the latest environmental data, thereby evaluating the safety status and health of workers in the mine.

[0102] Please refer to Figure 3 , in certain embodiments, the underground communication terminal is capable of;

[0103] Receiving a fourth device message sent by the information conversion device;

[0104] Based on the second preset filtering rule, the current environment information and the fourth device message are filtered to generate a first target message;

[0105] Based on the power line carrier communication technology, a first target message is sent to the ground communication terminal.

[0106] Specifically, the second preset filtering rule refers to a set of pre-set rules for the underground communication terminal to filter and process the message content according to these rules when processing and forwarding the first target message, which can optimize the data flow and ensure that the transmitted information is relevant and important, thereby improving communication efficiency and reducing unnecessary bandwidth occupation. First, filter according to the type of message (such as operation monitoring information, communication information, environmental monitoring data, etc.), and only forward messages of specific types. Second, according to the preset data range, only forward messages within a specific area or a specific time period to maintain the timeliness and relevance of the information. Third, set the priority according to the urgency or importance of the message to ensure that high-priority messages can be processed and forwarded first. Fourth, compress and simplify the message content, remove unnecessary information, and reduce the amount of data transmission. Fifth, errors may occur during the message transmission process. The second preset filtering rule includes an error detection and correction mechanism to ensure the accuracy and integrity of the message.

[0107] Power Line Carrier Communication (PLCC) is a communication technology that uses power lines as a communication medium. In underground mine communication systems, power line carrier communication technology can be used as an effective communication method for data transmission between underground communication terminals and ground communication terminals.

[0108] The underground communication terminal receives the fourth device message sent by the information conversion device. These messages contain the converted device status, operation monitoring information and communication information. Next, the underground communication terminal filters the current environment information and the fourth device message according to the second preset filtering rule. Then, the filtered information is integrated into the first target message. These messages contain key environmental parameters, device status and communication information, which are the core information that the ground communication terminal needs to receive and process. Finally, the underground communication terminal uses power line carrier communication technology to send the first target message to the ground communication terminal. This communication method uses the existing power lines in the mine, reducing the installation and maintenance costs of additional communication lines.

[0109] In this way, the underground communication terminal can not only serve as a key node in the communication network within the mine, but also as a center for environmental monitoring and data processing, ensuring that ground management personnel can receive key environmental and equipment information, thereby improving the communication efficiency and safety performance of the mine.

[0110] Please refer to Figure 3 , ground communication terminals can:

[0111] receiving a first target message sent by an underground communication terminal;

[0112] The first target message is analyzed and processed to generate a second target message.

[0113] Specifically, analysis and processing refers to the ground communication terminal analyzing and processing the received first target message, including data analysis, information integration and anomaly detection.

[0114] Data analytics refers to the analysis of environmental parameters to assess safety conditions within a mine.

[0115] Information integration refers to the integration of information from different mobile terminals and underground communication terminals to obtain a comprehensive view of the mine status.

[0116] Anomaly detection refers to identifying anomalies in environmental parameters or equipment status so that timely action can be taken.

[0117] The ground communication terminal can receive the first target message sent by the underground communication terminal, and then analyze and process the first target message to generate a second target message.

[0118] In this way, the ground communication terminal can not only ensure that ground managers receive key information, but also conduct in-depth analysis of this information to improve the quality and efficiency of decision-making, thereby enhancing the functionality of the entire underground mine communication system and enabling it to provide more comprehensive safety protection and efficiency improvement.

[0119] Please refer to Figure 3 , in some embodiments, the surface communication terminal is capable of sending the second target message to the underground communication terminal;

[0120] The underground communication terminal can send the received second target message to the first mobile terminal;

[0121] The first mobile terminal can send the received second target message to the second mobile terminal based on the preset data sharing technology.

[0122] Specifically, the ground communication terminal sends the generated second target message to the underground communication terminal. These messages may contain management instructions, safety warnings or other critical information. Then, the underground communication terminal receives the second target message from the ground communication terminal and forwards these messages to the first mobile terminal based on its configured functions. Then, after the first mobile terminal receives the second target message, it sends these messages to the second mobile terminal based on the preset data sharing technology. Finally, the second mobile terminal finally receives the second target message from the first mobile terminal, so that all key personnel in the mine can obtain the latest instructions and information.

[0123] In this way, through this closed-loop information transmission process, the underground mine communication system ensures the rapid circulation and sharing of information, improves the communication efficiency and response speed within the mine, thereby ensuring mine safety and improving the efficiency of work and response to emergencies.

[0124] See also Figure 4 The underground mine communication system also includes a third mobile terminal, which can communicate with the second mobile terminal or the first mobile terminal based on a preset data sharing technology.

[0125] Specifically, the addition of the third mobile terminal expands the communication network in the mine, allowing more equipment and personnel to participate in the communication system. This is particularly important for large or complex mine environments because it increases the coverage of the network and the reliability of communication.

[0126] In addition, the third mobile terminal can serve as a relay point for information, helping to spread critical information within the mine. For example, in an emergency, the third mobile terminal can receive alarm information from the first mobile terminal or the second mobile terminal and pass it on to other devices or personnel that are not directly connected.

[0127] In this way, by adding a third mobile terminal, the system achieves higher redundancy. If a mobile terminal fails or is out of communication range, other mobile terminals can take over its functions, ensuring the continuity and stability of the communication network.

[0128] See also Figure 5 The embodiment of the present application provides an underground mine signal extension method, the method is based on the above-mentioned underground mine communication system, and the method includes:

[0129] 01: The second mobile terminal sends the collected second device message to the first mobile terminal based on the preset data sharing technology;

[0130] 02: The first mobile terminal sends the collected first device message and the received second device message to the underground communication terminal;

[0131] 03: The underground communication terminal sends the collected current environment information, the received first device message and the received second device message to the ground communication terminal.

[0132] Specifically, the underground mine signal extension method provided in the embodiment of the present application is implemented based on the above-mentioned underground mine communication system. First, the second mobile terminal sends the collected second device message to the first mobile terminal based on the preset data sharing technology. Then, the first mobile terminal sends the collected first device message and the received second device message to the underground communication terminal. Finally, the underground communication terminal sends the collected current environment information, the received first device message and the received second device message to the ground communication terminal.

[0133] In this way, through the collaboration between the first mobile terminal and the second mobile terminal, and the connection with the underground communication terminal and the ground communication terminal, the comprehensiveness and efficiency of the internal communication of the underground mine are ensured. In addition, the ground management personnel can monitor the environment and equipment status inside the mine in real time and respond to various situations in a timely manner, thereby improving the safety and work efficiency of the mine. In addition, the system uses existing power lines and wireless communication technologies, and there is no need to establish independent communication links for each device, which simplifies the network structure, reduces costs, and improves the flexibility and scalability of the system.
