Description

Technical Field

[0003] The invention relates to the technical field of mine communication, and in particular to a mine HPLC wireless voice intercom method and system. Background Art

[0005] Real-time voice intercom in narrow and complex underground tunnels. Due to the reflection of wireless signals by the walls in the tunnels, the transmission distance of wireless signals underground is very short, and long-distance voice signal transmission is impossible. As a result, real-time voice intercom cannot be carried out in all tunnels in the entire mine. In the event of an emergency, the personnel in each tunnel underground cannot be notified in a timely and effective manner, which leads to a series of catastrophic consequences.

[0006] In the prior art, real-time voice signal intercom in underground tunnels is usually solved by pure wireless relay or Ethernet plus wireless method for underground signal coverage. However, both methods of the prior art have their own problems. The pure wireless relay voice intercom method consists of: wireless voice intercom and wireless repeater. Due to the narrowness of the underground tunnels, the reflection of wireless signals by the walls in the tunnels causes a large amount of overlap of wireless signals, which shortens the underground transmission distance exponentially. In order to solve the distance problem, it is necessary to increase signal repeaters. In order to solve the signal coverage problem in narrow and long tunnels, it is necessary to deploy multiple repeaters in the tunnels to amplify the signal, which leads to a further increase in the underground superimposed signals, resulting in an increase in the background noise of the wireless channel and a weakening of the effect of the wireless repeater. Moreover, this method cannot cover the entire mine, and can only provide signal coverage in local tunnels. It cannot be used for underground voice intercom, and can only be used locally in underground / above tunnels.

[0007] Another method of Ethernet plus wireless voice intercom consists of: Ethernet gateway, Ethernet router and wireless voice intercom. When communicating above and below the mine, the signal transmission mainly relies on the underground ring network. Real-time voice intercom cannot be carried out in places where the ring network cannot cover. For some special tunnels, Ethernet will be deployed for voice intercom, but the cost of deploying cables underground is too high, so it is usually not deployed throughout the mine. This leads to blind spots for voice intercom underground. Real-time intercom in underground tunnels: Generally, long-distance real-time intercom uses Ethernet for signal transmission, that is, the wireless intercom transmits the voice coding signal to the nearby Ethernet gateway, and the Ethernet gateway transmits it to the Ethernet gateway at the voice signal receiving end. The Ethernet gateway at the receiving end then converts the voice signal into a wireless voice coding signal and transmits it to the wireless intercom for voice playback. That is, a long-distance voice intercom is completed. Because this intercom system relies on Ethernet to transmit voice coded signals, it is still limited by the coverage of Ethernet. In addition, the voice intercoms usually used by Ethernet-based wireless intercoms are based on 2.4GHZ wireless communication. However, due to the poor ability of 2.4G wireless communication to bypass obstacles, the communication distance underground is usually not more than 200 meters. This further reduces the effective coverage of this system.

[0008] Therefore, a new solution is urgently needed to solve the problem that wireless signal coverage in underground tunnels is difficult and voice cannot be fully deployed underground. For example, the transmission of voice data and control data of wireless voice intercom equipment underground is less than 500Kbps, which solves the problem that the wireless signal of traditional intercom cannot be transmitted over long distances due to the narrow tunnels underground. Summary of the invention

[0010] In view of this, it is necessary to provide a mine-used HPLC wireless voice intercom method and system to solve the above-mentioned defects of the prior art.

[0025] Preferably, after turning on the terminal devices of all personnel, synchronizing all data in the database to all devices and systems, and completing the device access to the network, the method further includes:

[0026] Periodically transmit heartbeat packets to the attached HPLC gateway, so that the HPLC gateway can repackage data frames with its own ID after receiving the heartbeat packets and transmit them to the upper-level gateway until the data reaches the server;

[0027] The server stores the uploaded path information and locates the specific location of the wireless voice intercom in real time according to the path information.

[0028] Preferably, the voice intercom system based on the networking is configured to select an intercom mode to initiate voice communication to the target object, specifically including:

[0029] Select a talk mode from unicast, multicast or broadcast to initiate voice communication with the target party.

[0030] Preferably, the method further comprises:

[0031] The voice intercom system is monitored with low power consumption until the voice intercom system is turned off.

[0032] In a second aspect, an embodiment of the present invention provides a mining HPLC wireless voice intercom system, comprising:

[0033] A networking module is used to network the voice intercom system based on high-speed power line carrier communication and Sub-1G wireless communication technology to obtain a voice intercom system after networking is completed;

[0038] The processor is coupled to the memory and is used to execute the program stored in the memory to implement the steps in the mine-used HPLC wireless voice intercom method as described in the embodiment of the first aspect of the present invention.

[0039] In a fourth aspect, the present invention further provides a computer-readable storage medium for storing computer-readable programs or instructions, which, when executed by a processor, can implement the steps in the mining HPLC wireless voice intercom method as described in the embodiment of the first aspect of the present invention.

[0040] Compared with the prior art, the mine-used HPLC wireless voice intercom method and system provided by the present invention has the following beneficial effects:

[0041] 1) The present invention cleverly combines Ethernet, power line carrier signal HPLC and Sub-1G wireless communication technology through software algorithms to form a real-time voice communication system that can cover every corner of the mine. This allows the voice intercom system to cover the voice intercom signal from the mine to the mine and to each tunnel underground, allowing miners to use the system for voice intercom in any corner of the mine, greatly improving the probability of underground miners handling and escaping in an emergency.

[0042] 2) The present invention solves the problem of low-cost deployment and inability to fully cover wireless voice real-time intercom in ultra-long tunnels in large mines, allowing voice intercoms to be carried out in places with lighting underground, and the intercom can move freely in the tunnel at a maximum speed of 50km / hour without affecting the quality of voice intercoms. The wireless intercom can be used on foot or on rubber-wheeled vehicles, which increases the scope of use.

[0043] 3) Through this voice intercom system, the present invention realizes the functions of unicast intercom, multicast intercom and broadcast intercom of the intercom.

[0044] The voice intercom system can be used in a unicast mode for point-to-point intercom in daily use, so that all wireless intercoms in the mine can talk to each other at the same time without interfering with each other. This solves the privacy problem of intercom voice and the mutual interference problem between multiple groups of traditional intercoms talking at the same time.

[0045] The voice intercom system can be used in daily use in a multicast intercom mode, that is, a point-to-multipoint intercom mode, that is, voice data is transmitted between edge gateways without occupying the bandwidth of the backbone network, so that multiple intercom small systems divided by physical areas can be formed underground. This does not affect the voice intercom function when each intercom terminal reports the fault to the ground or other groups in the event of a major incident. This further improves the emergency response capability of the voice intercom system.

[0046] The voice intercom system can be used in daily use as a broadcast intercom, that is, one-to-all intercom throughout the mine. In other words, in case of major events, the intercoms underground or above the mine can broadcast emergency events or commands to the entire mine in a timely and effective manner, ensuring the safety of miners.

[0047] 4) Through this voice intercom system, each intercom terminal can transmit short message data in unicast / multicast / broadcast mode, so that the LCD message display function, i.e. dual information transmission, can be enabled in high-noise scenes underground, solving the problem of voice failure and inability to interact with information in special high-noise scenes. This function can be used to upload pictures or transmit information by text input.

[0048] 5) The voice intercom system provided by the present invention adopts an ultra-low power consumption design in consideration of the time it takes for miners to go down the mine. That is, the standby time can be set from 1 hour to 72 hours according to the usage habits, thereby solving the problem of consuming all the battery power due to forgetting to turn off the machine. Due to the use of a special intermittent monitoring low power consumption mode, the maximum working time of the wireless intercom in the monitoring mode is greater than 72 hours.

[0057] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0058] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0059] Real-time voice intercom in narrow and complex underground tunnels. Due to the reflection of wireless signals by the walls in the tunnels, the transmission distance of wireless signals underground is very short, and long-distance voice signal transmission is impossible. As a result, real-time voice intercom cannot be carried out in all tunnels in the entire mine. In the event of an emergency, the personnel in each tunnel underground cannot be notified in a timely and effective manner, which leads to a series of catastrophic consequences.

[0060] In view of this, the present invention provides a mine-used HPLC wireless voice intercom method, which is used for effective full coverage of real-time voice intercom in underground mine tunnels. The following will be described and introduced through multiple embodiments.

[0061] Figure 1 The flowchart of the mine HPLC wireless voice intercom method provided by the present invention is shown in FIG. Figure 1 The mine-used HPLC wireless voice intercom method provided by the present invention comprises:

[0062] S1. Based on high-speed power line carrier communication and Sub-1G wireless communication technology, a voice intercom system is networked to obtain a voice intercom system after networking is completed;

[0063] S2. Based on the voice intercom system after the networking is completed, select an intercom mode to initiate voice communication to the target object, so that the voice communication device of the target object receives the voice broadcast message;

[0064] S3, completing the intercom after receiving the voice response message fed back by the target object in the same intercom mode.

[0065] Figure 2 The topological structure diagram of the voice intercom system provided by the present invention is shown in FIG. Figure 2 The present invention changes the method of increasing the range of real-time voice intercom underground by relying on Ethernet and wireless repeaters into a system that uses the original power line to load a carrier signal (HPLC) in the tunnels of the entire mine to remotely transmit real-time voice data and display the information of the intercom object. At the end of the network, the Sub-1G gateway on the power line is used to provide wireless signal coverage for the edge tunnels. The original power lines in the tunnels are used to transmit real-time voice intercoms by cable line carrier. Wireless voice intercoms can be carried out wherever there is electricity underground, allowing people with handheld intercoms to move freely in the tunnels. The voice intercom can switch seamlessly among the Sub-1G gateways installed in the tunnels without affecting the quality of the voice call. It gets rid of the restrictions on the use boundaries of underground wireless intercoms, allowing a borderless real-time voice intercom system to be formed above and below the coal mine. Combined with step S1, the embodiment of the present invention is actually a networking system generated by combining the technology of high-speed power line carrier communication (High-speed Power Line Communications) and Sub-1G wireless communication with the existing layout, and combined with the self-developed software algorithm of the embodiment of the present invention, a real-time voice communication system that can cover every corner of the wellbore is formed.

[0066] Figure 3 is a schematic diagram of a system debugging process provided by an embodiment of the present invention, combined with Figure 3As shown in the content, the process of the embodiment of the present invention can actually be divided into the networking process of step S1 and the voice intercom process of steps S2 and S3. In step S1, device registration, gateway grouping, file synchronization to the gateway and intercom, and device access to the network are completed. In steps S2 and S3, selection of unicast / multicast / broadcast intercom and idle monitoring are completed.

[0067] Based on the above solutions, the embodiments of the present invention achieve full coverage of voice intercom signals from the surface to the underground and in each tunnel underground, as well as a convenient, fast and stable voice call function.

[0068] Based on the above embodiments, Figure 4 is a schematic diagram of a networking process provided by an embodiment of the present invention, such as Figure 4 As shown, the voice intercom system is networked based on high-speed power line carrier communication and Sub-1G wireless communication technology to obtain a voice intercom system after networking, which specifically includes:

[0069] Enter the HPLC gateway information and intercom device ID information in the voice intercom system, and complete the binding of equipment and personnel;

[0070] Group the HPLC gateways according to the communication boundaries and store the grouped data in the database;

[0071] Turn on the terminal devices of all personnel, synchronize all data in the database to all devices and systems, and complete the device network access.

[0072] It is understandable that the embodiment of the present invention must first connect the information of all devices to the system and test them before they can be used normally. Figure 4 The complete detailed process of the networking process includes:

[0073] After the backbone network is built, the system enters the HPLC gateway information and intercom device ID information;

[0074] Then bind the intercom ID and the name of the person who receives it;

[0075] Then, the HPLC gateways are grouped according to the boundaries of multicast and broadcast, and each group is given a special name according to its usage scenario;

[0076] Store the grouped archives in the system's database;

[0077] Open all terminals and synchronize the device files in the system to all mobile intercoms and HPLC gateways;

[0078] Finally, the network access test is carried out until all devices are debugged successfully and the network is completed.

[0079] On the basis of the above embodiment, the HPLC gateway information and intercom device ID information are input into the voice intercom system, and the binding between the device and the personnel is completed, specifically including:

[0080] Record the device IDs of the above-ground intercom, the underground Ethernet HPLC gateway, the HPLC wireless gateway, and the wireless intercom;

[0081] Bind the device ID with the user information and display the device location in 3D on the GIS map.

[0082] It can be seen from the above embodiments that the first step of networking is to complete the binding record of equipment and gateways. Specifically, the present invention is to bind the intercoms in the aboveground part, the Ethernet HPLC gateway, HPLC wireless gateway, wireless intercom and other equipment in the underground part. These equipment are equipped with unique IDs when they leave the factory. After being installed at the project site, these IDs need to be bound one by one with the installation location and the user to form equipment files and enter these files into the system as the location elements of the mine GIS map. Then, the equipment information entered into the system is spread on the mine GIS map according to the installation location for 3D display.

[0083] On the basis of the above embodiment, the HPLC gateways are grouped according to the communication boundary, and the grouped data is stored in the database, specifically including:

[0084] Determine the number of intercoms in the above-ground part of the functional area, the number of Ethernet HPLC gateways, the number of HPLC wireless gateways, and the number of wireless intercoms in the underground part;

[0085] Count the device IDs in the area, and then create sub-files as the communication boundaries of the group.

[0086] Specifically, the present invention needs to group devices and gateways. This is because after the intercoms in the above-ground part of the mine and the Ethernet HPLC gateways, HPLC wireless gateways, wireless intercoms and other equipment in the underground part are installed, in order to improve the intercom efficiency and reduce the mutual interference between voice receivers when multiple people use them at the same time, it is necessary to group the equipment according to the functional areas in the mine for business functions during non-emergency intercoms, such as the main mining area of ​​Group A, the shaft area of ​​Group B, the mining area of ​​Group C, etc. for business function area division.

[0087] After the division, the voice intercom between the devices in group A of the system cannot be monitored by any device in group B and group C, and the intercom between the devices in group B cannot be monitored by group A and group B either. In this way, the system uses the device ID to effectively physically isolate the business area, reducing the probability of congestion during voice data transmission in the main communication loop, so that the voice data transmitted by the wireless intercom in the non-cross-business area is only transmitted on the main road of the area, without occupying the data transmission channel of other business areas, thereby reserving a smooth voice data transmission channel for the emergency broadcast of high-priority voice commands to the whole mine. It truly achieves high-throughput real-time voice intercom for the whole mine.

[0088] The specific functional area division is based on the number of walkie-talkies in the above-ground part of the functional area, the number of Ethernet HPLC gateways, the number of HPLC wireless gateways, the number of wireless walkie-talkies in the underground part, and the ID of each device in the area, and then a sub-file is established to determine the area boundary of this group.

[0089] Finally, the regional archives need to be stored on the server for backup so that the regional records will not be lost or confused.

[0090] On the basis of the above embodiment, after opening the terminal devices of all personnel, synchronizing all data in the database to all devices and systems, and completing the device access to the network, the method further includes:

[0091] Periodically transmit heartbeat packets to the attached HPLC gateway, so that the HPLC gateway can repackage data frames with its own ID after receiving the heartbeat packets and transmit them to the upper-level gateway until the data reaches the server;

[0092] The server stores the uploaded path information and locates the specific location of the wireless voice intercom in real time according to the path information.

[0093] After the device files are established and divided into regions in the system, the entire file list needs to be downloaded to each terminal device as the basis for terminal unicast / multicast / and broadcast, and as the basis for the lookup table of the incoming device.

[0094] Then perform file synchronization. The specific process of synchronization includes:

[0095] Place the intercom in the area covered by the HPLC gateway signal, and then turn on the machine;

[0096] Click the file synchronization function and wait for the file synchronization to complete;

[0097] After the intercom completes file synchronization, it will prompt "File download successful";

[0098] Return to the main menu and select the intercom mode before transmitting the intercom voice signal, i.e. unicast / multicast / broadcast;

[0099] Then press the PTT button to pick up and transmit voice signals.

[0100] After synchronizing the files, the wireless voice intercom device will periodically send a heartbeat packet to the attached HPLC gateway. After receiving the heartbeat packet, the HPLC gateway will repackage the data frame with its own ID and send it to the upper-level gateway, and so on until the data reaches the server. At this time, the server will store the uploaded path information. Based on this path information, the server can locate the specific location of the wireless voice intercom in real time.

[0101] When the location information of all wireless voice intercoms in the system is uploaded, the server can allocate the best transmission path for voice intercom in real time according to the location information, so as to quickly deliver the voice data to the target monitored wireless intercom for voice broadcast.

[0102] On the basis of the above embodiment, the voice intercom system based on the completed networking selects an intercom mode to initiate voice communication to the target object, specifically including:

[0103] Select a talk mode from unicast, multicast or broadcast to initiate voice communication with the target party.

[0104] Figure 5 Schematic diagram of the voice intercom process provided by the embodiment of the present invention. Figure 5 As shown in the figure, the voice intercom process specifically includes:

[0105] After the device is started, the user list and multicast table are loaded. The user selects an intercom method from unicast, multicast or broadcast to initiate voice communication with the target object. The operation is to press the intercom start button, and the system will start picking up sound and performing voice encoding, and then send voice according to the selected intercom object, and then enter the monitoring state.

[0106] The target object receives the voice broadcast and displays the caller name and intercom method. The target object responds in the same way. After answering, it also enters the monitoring state to determine whether to continue the call within the set time. If not, it will shut down to save power.

[0107] Specifically, three intercom modes are provided in the embodiment of the present invention.

[0108] That is, one of the three modes of unicast / multicast / broadcast for voice intercom. If no selection is made, the last mode will be used by default.

[0109] Unicast is point-to-point voice intercom. The voice intercom signal transmitted by the transmitter can only be received and decoded by the target receiving intercom for voice broadcast. Other devices cannot receive, decode or broadcast.

[0110] Multicast is a point-to-multipoint voice intercom. The voice intercom signal transmitted by the transmitter can only be received, decoded and broadcasted by the intercom devices in the selected multicast list. Devices outside the group cannot decode and broadcast. That is, the voice signal transmitted by any device in the selected group can be monitored by all devices in the entire group.

[0111] Broadcasting is a one-to-all voice intercom. The voice intercom signal transmitted by the transmitter can be received, decoded and broadcasted by all devices in the system. That is, any intercom working in the monitoring state in the system can receive, decode and broadcast all the voice data in the system.

[0112] Based on the above embodiment, the method further includes:

[0113] The voice intercom system is monitored with low power consumption until the voice intercom system is turned off.

[0114] refer to Figure 5 As shown, the embodiment of the present invention substantially further provides the system with an idle monitoring function, and the idle monitoring function is specifically:

[0115] The wired intercom in the system will enter low-power monitoring state after being turned on until it is turned off;

[0116] The wireless voice intercom in the system enters a low-power monitoring state after being turned on. When the continuous monitoring time exceeds the automatic sleep time set by the system, it will automatically shut down to save battery power;

[0117] When the PTT button is pressed, the wired and wireless intercoms are in voice pickup and transmission state. When the PTT button is released, they are in monitoring state. In monitoring state, the intercom receives voice data and decodes and broadcasts it in real time.

[0118] After receiving the voice data, the LCD screen of the intercom will immediately display the name and location information of the data source, and broadcast the received voice at the same time. The display content of the LCD screen will be cleared 2 seconds after the broadcast is completed.

[0119] It is understandable that due to the issue of miners' time going down the mine and ensuring their production safety, this power-saving design can help them to maintain communication for a long time to the greatest extent, and will not cause unnecessary panic due to communication power outages.

[0120] The embodiment of the present invention also provides a mine-used HPLC wireless voice intercom system, comprising:

[0121] A networking module is used to network the voice intercom system based on high-speed power line carrier communication and Sub-1G wireless communication technology to obtain a voice intercom system after networking is completed;

[0122] A voice intercom module, for selecting an intercom mode from the voice intercom system after the networking is completed to initiate voice communication to a target object, so that the voice communication device of the target object receives a voice broadcast message;

[0123] After receiving the voice response message fed back by the target object in the same intercom mode, the intercom is completed.

[0124] The specific working mode of the system can be referred to the above embodiment, and the embodiment of the present invention will not be described in detail here.

[0125] Compared with the prior art, the mine-used HPLC wireless hybrid network communication method and system provided by the present invention have the following beneficial effects:

[0126] 1) The present invention cleverly combines Ethernet, power line carrier signal HPLC and Sub-1G wireless communication technology through software algorithms to form a real-time voice communication system that can cover every corner of the mine. This allows the voice intercom system to cover the voice intercom signal from the mine to the mine and to each tunnel underground, allowing miners to use the system for voice intercom in any corner of the mine, greatly improving the probability of underground miners handling and escaping in an emergency.

[0127] 2) The present invention solves the problem of low-cost deployment and inability to fully cover wireless voice real-time intercom in ultra-long tunnels in large mines, allowing voice intercoms to be carried out in places with lighting underground, and the intercom can move freely in the tunnel at a maximum speed of 50km / hour without affecting the quality of voice intercoms. The wireless intercom can be used on foot or on rubber-wheeled vehicles, which increases the scope of use.

[0128] 3) Through this voice intercom system, the present invention realizes the functions of unicast intercom, multicast intercom and broadcast intercom of the intercom.

[0129] The voice intercom system can be used in a unicast mode for point-to-point intercom in daily use, so that all wireless intercoms in the mine can talk to each other at the same time without interfering with each other. This solves the privacy problem of intercom voice and the mutual interference problem between multiple groups of traditional intercoms talking at the same time.

[0130] The voice intercom system can be used in daily use in a multicast intercom mode, that is, a point-to-multipoint intercom mode, that is, voice data is transmitted between edge gateways without occupying the bandwidth of the backbone network, so that multiple intercom small systems divided by physical areas can be formed underground. This does not affect the voice intercom function when each intercom terminal reports the fault to the ground or other groups in the event of a major incident. This further improves the emergency response capability of the voice intercom system.

[0131] The voice intercom system can be used in daily use as a broadcast intercom, that is, one-to-all intercom throughout the mine. In other words, in case of major events, the intercoms underground or above the mine can broadcast emergency events or commands to the entire mine in a timely and effective manner, ensuring the safety of miners.

[0132] 4) Through this voice intercom system, each intercom terminal can transmit short message data in unicast / multicast / broadcast mode, so that the LCD message display function, i.e. dual information transmission, can be enabled in high-noise scenes underground, solving the problem of voice failure and inability to interact with information in special high-noise scenes. This function can be used to upload pictures or transmit information by text input.

[0133] 5) The voice intercom system provided by the present invention adopts an ultra-low power consumption design in consideration of the time it takes for miners to go down the mine. That is, the standby time can be set from 1 hour to 72 hours according to the usage habits, thereby solving the problem of consuming all the battery power due to forgetting to turn off the machine. Due to the use of a special intermittent monitoring low power consumption mode, the maximum working time of the wireless intercom in the monitoring mode is greater than 72 hours.

[0135] In some embodiments, the memory 602 may be an internal storage unit of a computer device, such as a hard disk or memory of the computer device. In other embodiments, the memory 602 may also be an external storage device of the computer device, such as a plug-in hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (SecureDigital, SD) card, a flash card (Flash Card), etc. equipped on the computer device.

The memory 602 is used to store application software and various types of data installed in the computer device, such as program codes installed in the computer device. The memory 602 may also be used to temporarily store data that has been output or is to be output. In one embodiment, when the mining HPLC wireless voice intercom program 603 is executed by the processor 601, the following steps are implemented:
