A comprehensive communication network is an essential foundation for intelligent mine safety production and management. In the construction of underground mine communication networks, the main network often consists of fiber optic cables and 5G / 4G base stations. Deploying this type of network requires laying fiber optic cables separately along the mining access road, and then deploying each base station sequentially along the fiber optic cables. The problem is that laying fiber optic cables in the complex environment of the mining access road is difficult and unsuitable for most mine tunnel scenarios. Currently, most mines, in order to save costs, do not even lay fiber optic cables or deploy communication networks within the mining access road, seriously affecting the work quality and personnel safety within the mining access road.

[0044] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0045] Example 1:

[0046] Embodiment 1 of this utility model provides a communication relay system suitable for the networking needs of non-coal underground mines, such as... Figure 1 As shown, it includes: multiple multi-network converged routers 1, power supply lines 2, and a main network 3, wherein:

[0047] The power supply line 2 extends along the extension direction of the mining route 4. At least one multi-network fusion router 1 is installed on the power supply line 2 at a first preset distance, and two adjacent multi-network fusion routers 1 are connected through the power supply line 2. The main network 3 is located outside the entrance of the mining route 4. The main network 3 is connected to the multi-network fusion router 1 closest to the entrance of the mining route 4 through a network cable or optical fiber. Multiple multi-network fusion routers 1 are connected in a step-by-step manner to extend the wireless network to the entire mining route 4, ensuring that the mining route 4 can be covered by wireless signals and realizing the transmission and reception of wireless signals within the mining route 4.

[0048] In this embodiment, the mining access route 4 can refer to the interior of the mine tunnel, and the extension direction of the mining access route 4 is the extension direction of the mining tunnel. The power supply line 2 is set in the same direction as the extension of the mining access route 4, and the power supply line 2 provides power to the multi-network converged route 1.

[0049] Furthermore, the power supply line 2 can provide power to the lighting devices inside the mine tunnel, which illuminate the interior of the mine tunnel to ensure normal operation inside the mine tunnel and are essential facilities inside the mine tunnel.

[0050] The main network 3 can be a 4G / 5G base station for signal processing and signal reception and transmission. The multi-network converged router 1 is equipped with corresponding interfaces and wireless signal transceiver modules to transmit data through network signals; the multi-network converged router 1 can also transmit signals through the power line 2 based on power line carrier technology to realize the transmission and reception of wireless signals within the back sampling route 4.

[0051] In this embodiment, as Figure 1 and Figure 3As shown, the multi-network converged router 1 is equipped with a power line carrier communication module 14. The power line carrier communication module 14 superimposes high-frequency communication signals onto the power current to achieve data transmission over the circuit. Therefore, in this embodiment, by leading two wires from the power supply line 2 and electrically connecting them to the positive and negative terminals of the power line carrier communication module 14 respectively, the multi-network converged router 1 is electrically connected to the power supply line 2. Data transmission and reception between the main network 3 and each multi-network converged router 1 are achieved through the power supply line 2 and the optical fiber at the entrance of the mining access road 4. Multiple multi-network converged routers 1 provide wireless signal coverage within the mining access road 4, enabling personnel positioning and data collection and uploading within the mining access road 4, thus solving the signal blind spot problem within the mining access road 4. Since lighting is essential for operations in the mining access road 4, the power supply line 2 must be laid and deployed within the mining access road 4. In this embodiment, signal transmission between the multi-network converged routers 1 is directly completed using the power supply line 2, eliminating the need for additional optical fiber deployment, thus reducing deployment costs and difficulty.

[0052] Furthermore, such as Figure 2 As shown, a monitoring device 5 is also installed between two adjacent multi-network fusion routes 1 in the same mining route 4. The monitoring device 5 is connected to the adjacent multi-network fusion route 1 through the power supply line 2. In this embodiment, the monitoring device 5 is used to monitor the environment inside the mining route 4 and transmit the monitored data to the nearest multi-network fusion route 1. After processing the received data, the multi-network fusion route 1 transmits the data to the external main network 3 through the power supply line 2 to realize the uploading of monitoring data.

[0053] In this embodiment, the first preset distance is set by those skilled in the art based on actual conditions.

[0054] It is worth mentioning that, in this embodiment, as Figure 2 and Figure 3 As shown, multiple mining routes 4 can coexist. The entrance of each mining route 4 leads to the lower plate transport roadway. Therefore, the main network 3 can be set in the lower plate transport roadway. The first multi-network converged route 1 in each mining route 4 is connected to the main network 3 through optical fiber or network port 12. The power supply line 2 in each mining route 4 is also led out from the entrance of the mining route 4 to the lower plate transport roadway, and after being uniformly connected in the lower plate transport roadway, it is led out to the outside of the lower plate transport roadway and connected to the power source to supply power to each power supply line 2.

[0055] Furthermore, considering that multi-network converged router 1 needs to send and receive corresponding data, and also needs to connect with other multi-network converged routers 1, and may also need to connect with the main network 3, this embodiment also involves the following design:

[0056] like Figure 3 As shown, the multi-network converged router 1 specifically includes: a main control chip 11, a network port 12, an optical fiber interface 13, and a power line carrier communication module 14, wherein: the main control chip 11 is connected to the network port 12, the optical fiber interface 13, and the power line carrier communication module 14 respectively; the network port 12 or the optical fiber interface 13 in the multi-network converged router 1 closest to the entrance of the back sampling route 4 is connected to the main network 3; the power line carrier communication module 14 is connected to the power supply line 2.

[0057] In this embodiment, the power line carrier communication module 14 in the multi-network converged router 1 is used to connect to the power line carrier communication module 14 in another multi-network converged router 1 through the power supply line 2, so as to realize the hierarchical connection of the multi-network converged router 1. Different multi-network converged routers 1 can transmit data and control signals through the power line carrier communication module 14 and the power supply line 2.

[0058] In this embodiment, the main control chip 11 is used to call and control each port, process the data received by each port, and send the data through each port. The main control chip 11 can also store the received data.

[0059] Furthermore, since the multi-network converged router 1 needs to realize the transmission and reception of wireless data in the back sampling route 4, the multi-network converged router 1 also needs to be equipped with a corresponding wireless communication module. Therefore, this embodiment also involves the following design:

[0060] like Figure 3 As shown, the multi-network converged router 1 further includes: a 4G communication module 15, a Wi-Fi communication module 16, and a LoRa communication module 17; the 4G communication module 15, Wi-Fi communication module 16, and LoRa communication module 17 are all connected to the main control chip 11; the 4G communication module 15, Wi-Fi communication module 16, and LoRa communication module 17 are all used for wireless communication.

[0061] Furthermore, through actual measurements, it was found that the Wi-Fi signal of the Wi-Fi communication module 16 propagates over a distance of approximately 30m in the mining path 4, and the LoRa signal of the LoRa communication module 17 propagates over a distance of approximately 100m in the mining path 4. To ensure the effectiveness of the propagation of both signals, this embodiment also involves the following design: the first preset distance is 60±5m. In this embodiment, the first preset distance can be 55m, 60m, or 65m.

[0062] Furthermore, in this embodiment, the plurality of multi-network converged routers 1 are connected step-by-step through power supply lines 2; or the plurality of multi-network converged routers 1 are connected step-by-step through any one of Wi-Fi and LoRa wireless modes.

[0063] like Figure 3 As shown, the multi-network converged router 1 also includes: a binocular camera 18; the binocular camera 18 is connected to the main control chip 11; the binocular camera 18 is used to monitor the interior of the back-collection route 4.

[0064] In this embodiment, as Figure 3 As shown, the first multi-network converged router 1 in the mining route 4 can be connected to the main network 3 via a 4G communication module 15, a Wi-Fi communication module 16, or a LoRa communication module 17. Multiple multi-network converged routers 1 in the mining route 4 extend the coverage of 4G, Wi-Fi, and LoRa wireless networks in the mining route 4 via 4G communication modules 15, Wi-Fi communication modules 16, and LoRa communication modules 17. Simultaneously, these modules provide network access for workers in the mining route 4. Workers' mobile phones or cameras connect to the network via Wi-Fi, while industrial equipment in the mining route 4 connects via LoRa. Furthermore, through these network functions, personnel identification and location tracking can also be achieved. The corresponding implementation steps are as follows:

[0065] S1: Define the IP naming rules for multi-network converged route 1, such as associating mining level, mining area, connection order and location characteristics with the IP address of multi-network converged route 1, so that the IP address can reflect the location characteristics of the underground mining area where multi-network converged route 1 is located.

[0066] S2: Establish a mapping relationship between personnel identity information and mobile phone MAC address, and import the IP rules of the multi-network converged router 1 as a whitelist into the mobile phone held by the operator, thereby ensuring that the multi-network converged router 1 can obtain the real MAC address of the wirelessly connected mobile phone and then resolve the personnel identity.

[0067] S3: The multi-network converged router 1 has a dual-lens camera 18, which is arranged on both sides of the multi-network converged router 1. The dual-lens camera 18 identifies the speed, direction and distance of personnel movement, and combines the changes in the signal strength index value of the mobile phone to achieve accurate positioning of personnel.

[0068] Furthermore, considering the complex environment beneath the mine shaft, localized network outages may occur. To prevent data loss during network outages in the various multi-network converged routers 1, this embodiment also involves the following design:

[0069] like Figure 4 As shown, the main control chip 11 includes one or more of a memory module 111, a flash memory module 112, and a TF expansion card 113.

[0070] In this embodiment, the memory module 111, flash memory module 112, and TF expansion card 113 serve as a three-level storage system, and the multi-network converged router 1 performs functions such as collecting, packaging, and storing internal monitoring equipment data, engineering equipment data, and personnel positioning data. The three-level storage implementation of the multi-network converged router 1 is as follows: First, the received data is parsed into a unified data format, such as JSON, in the memory module 111. Then, according to the set overflow conditions (such as when the memory module 111 usage reaches 50%, when the battery module 19 capacity is less than 20%, or every 10 minutes), the data is written to the flash memory module 112, and the memory module 111 is cleared. Second, when the data in the flash memory module 112 reaches the preset conditions (such as when the storage space utilization rate in the flash memory module 112 reaches 50% or the time exceeds 15 days), the data in the flash memory module 112 is transferred to the TF expansion card 113, and the flash memory module 112 is cleared. Third, the data in the TF expansion card 113 can be deleted according to the set conditions (such as when the storage time exceeds 30 days or the storage space utilization rate exceeds 80%). Before deleting the data in the TF expansion card 113, data integrity verification is required to ensure that all data has been uploaded to the server for storage. Among them, the video and audio formats support H.264 and H.265 data compression functions, are transmitted using streaming media technology, and are not stored locally.

[0071] Furthermore, in this embodiment, considering the complex environment beneath the mine shaft and the possibility of localized power outages, to prevent the multi-network converged router 1 from shutting down directly in the event of a power outage, this embodiment also involves the following design:

[0072] like Figure 5 As shown, the multi-network converged router 1 also includes a battery module 19; the battery module 19 is connected to the main control chip 11.

[0073] In this embodiment, the power line carrier communication module 14 can transmit signals step by step whether the power supply line 2 is energized or de-energized. When there is no power outage, the power supply line 2 is energized, and adjacent multi-network converged routers 1 can operate normally by being powered by the power supply line 2, while charging the battery module 19. When a power outage occurs, the power supply line 2 is de-energized, and the multi-network converged router 1 maintains normal operation of the device through the battery module 19. The main control chip 11 in the multi-network converged router 1 can realize the switching between charging and power supply modes of the battery module 19.

[0074] Furthermore, the data collected by the multi-network converged router 1 has a remote server write verification and breakpoint resumption mechanism. For example, using the explicit acknowledgment (ACK) response mode, the server returns confirmation to the application layer after processing the data. If the client does not receive the ACK, a retry is triggered. Data collected during power outages and network outages is managed according to the above three-level storage strategy, and the time points of power outages and network outages are automatically recorded. When power and network are restored, data is resumed according to the timestamp.

[0075] Furthermore, considering that there are usually multiple mining routes 4, and the entrances of these multiple mining routes 4 are the main haulage roadways in the lower deck, which are usually areas with relatively high personnel activity, it is even more necessary to ensure wireless signal coverage at this location. Therefore, this embodiment also involves the following design: Figure 2 As shown, a wireless base station 6 is also installed at the entrance of the mining route 4.

[0076] Furthermore, such as Figure 2 As shown, when there are multiple mining routes 4, the communication relay system applicable to the networking of non-coal underground mines also includes a main power supply line 7, wherein: the main power supply line 7 is located outside the entrance of all mining routes 4 and is connected to the power supply line 2 in all mining routes 4 respectively; the main power supply line 7 is connected to an external power source to supply power to all power supply lines 2.

[0077] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
