Description

Technical Field

[0001] The present invention relates to the technical field of coal mine safety, and in particular to a three-dimensional fusion dispatching platform for mines. Background Art

[0002] With the expansion of coal mining scale and the continuous improvement of coal mine safety production requirements, various subsystems such as coal mine staff, equipment, environmental monitoring, video monitoring, automation, and information are also increasing. Therefore, with the continuous increase in the number of underground access services in the transmission system, the demand for mine main transmission has shown a diversified development trend. Information from various systems such as underground coal mine environmental monitoring, personnel positioning, wireless communication, water pump monitoring, tape control, disaster avoidance and relief must be transmitted through the mine main transmission network, and the mine main transmission equipment must also meet the access requirements of different equipment in various systems, which puts higher requirements on indicators such as latency, capacity, and anti-interference of the communication system.

[0003] From the perspective of large-scale mines across the country, PHS, 2G and 3G communication systems have been gradually replaced and eliminated, and WiFi / 4G wireless communication systems are more commonly used. In recent years, the newly invested 5G and WiFi6 wireless converged communication systems are gradually maturing. The main disadvantage of the 4G wireless communication system for mines is that the bandwidth and real-time indicators cannot meet the requirements of application scenarios such as high-definition intelligent video and remote control. The promotion and use of 5G wireless communication systems for mines is still in its infancy. In terms of terminals, 5G mobile phones and mining CPE have obtained relevant coal safety certification and have the conditions for underground application. Mining products involving R16 NB-IoT have not yet completed coal safety certification. The WiFi6 wireless communication system has the advantages of simple structure, low cost, and high transmission rate, but the latency is high, the mobility and reliability are relatively low, and the mobile phone terminals are relatively immature, which affects the quality of voice calls.

[0004] At present, the demand for wireless communication systems in coal mines is mainly reflected in the following aspects: (1) Large bandwidth demand. Meet the needs of large data transmission such as mobile video monitoring, virtual mine construction, and multimedia scheduling. (2) Low latency and high reliability demand. Ensure the transmission quality of voice and high-definition video and the timeliness and reliability of remote control functions. (3) Multi-access demand. Meet the access of sensor data such as operating parameters and environmental parameters of a large number of electromechanical equipment. (4) Location information demand. Applications such as human-machine operation safety, intelligent collaborative operation, unmanned transportation, and underground robots are inseparable from the demand for location information. (5) Multi-system and multi-interface integration demand. Meet the different requirements and integration of environmental monitoring and control systems, video surveillance systems, IP broadcasting systems, information release systems, and various devices for interfaces. (6) Scenario linkage demand. Connect to various smart mine platforms, including personnel positioning systems, auxiliary transportation systems, video surveillance systems, etc., interact and communicate in specific scenarios, and conduct unified dispatch and command. For example, if an evacuation message is sent up and down in the personnel positioning system, the wireless communication system can be linked to automatically make an emergency call or make an emergency broadcast notification to the underground workers. Although domestic manufacturers have developed various wireless communication systems, there are still some major problems:

[0005] (1) Failure to integrate multiple communication methods: Due to historical reasons, most coal mines have multiple communication systems, from wired to wireless, from analog to digital, from bus to Ethernet, from technologies more than a decade ago to the latest technologies, and systems can be found in operation in coal mines. The separate operation of multiple communication methods will inevitably bring maintenance costs, so it is necessary to integrate multiple communication methods.

[0006] (2) No unified system management: Currently, coal mines use multiple communication systems for different applications, including voice call systems, broadcasting systems, and old-fashioned program-controlled switch analog telephone communication systems. The simultaneous use of multiple communication systems cannot bring efficient management and scheduling to the mine, so unified management of multiple communication systems is required.

[0007] (3) Lack of linkage between systems: Due to different construction times and different technical methods used, as well as various practical reasons during construction, the various systems that have been built in coal mines are independent of each other and become "isolated islands". There is no communication and interaction between systems. In addition, several different systems may exist in a mine at the same time, but each system is independent of each other and cannot communicate with each other at critical moments, lacking unified dispatch and command. Therefore, it is necessary to link various intelligent systems in mines through wireless communication systems in specific scenarios to achieve the goal of intelligent mines. Summary of the invention

[0008] The present invention provides a three-dimensional fusion dispatching platform for mining, which adopts a combination of wireless and wired Ethernet, can adapt to complex and harsh working environments, has flexible wiring, and effectively realizes mutual communication of video and audio.

[0009] The present invention provides a three-dimensional fusion scheduling platform for mining, including a server and a client. The server communicates with the client, is connected to other linkage subsystems, and is connected to core network services and outgoing services. The server consists of four parts and is uniformly managed through Docker Compose. Docker Compose uses a configuration file in YAML format to configure the services of an application, including containers, networks, and volumes. A user defines the dependencies between multiple containers in a declarative manner through the configuration file, and then starts or shuts down these containers simultaneously through one command.

[0010] Furthermore, the server includes a scheduling module, a Sip service module, a database module and a voice conversion module. The scheduling module is respectively connected to the client, other linkage subsystems, the Sip service module and the database module. The Sip service module is also connected to the voice conversion module, as well as to the core network service and the outgoing service.

[0011] Furthermore, the Sip service module is based on freeswitch and provides basic services, including sip account registration, session establishment and release, and voice packet forwarding recording. The Sip service module is used to provide command and dispatch functions with multimedia clusters and audio and video consultations as the core. It supports the access of media and terminals of various networks through access gateway docking, including video surveillance, conference terminals, wired telephones, emergency broadcasting, 4G / 5G mobile phones, and smart miners' lamps; at the same time, it also serves as the main connection part for docking with the 4G / 5G core network and outbound, realizing unified dispatch with the 4G / 5G core network and other communication systems.

[0012] Furthermore, the scheduling module serves as a scheduling backend, provides a restfull http interface to the outside world, and performs linkage business processing with other linkage subsystems to realize core business functions for the platform, including video surveillance, video consultation, and GIS scheduling; among which, the other linkage subsystems include a video surveillance subsystem and a personnel positioning subsystem.

[0013] Furthermore, for terminals that do not support the video call protocol in the Sip service module, it is linked with the video surveillance subsystem to realize the video call function through SIP voice + video streaming; it communicates with the Sip service module in real time to realize the unified dispatching and control of the control and command center.

[0014] Furthermore, the database module provides data access capabilities for the Sip service module and the scheduling module.

[0015] Furthermore, the voice conversion module is used to convert text information into natural and fluent voice output, providing a text-to-speech function; the voice conversion module interacts with the Sip service module through the MRCP protocol to implement the scheduling function of text broadcasting.

[0016] Furthermore, the client is implemented by QT, which is a cross-platform graphical user interface application development framework for building high-performance desktop, mobile and Web applications; the client monitors by communicating with the scheduling module, and the communication methods are http request and websocket.

[0017] Furthermore, through the communication between the client and the server, the functions of voice scheduling, video scheduling, GIS scheduling, cluster intercom, integrated conference, and instant messaging are realized, and the usage process is as follows: the terminal is connected to the freewitch-based SIP service module, and communicates and interacts with the scheduling module and the client in real time to realize the functions of voice scheduling, video scheduling, cluster intercom, integrated conference, instant messaging, etc., and the scheduling module is linked with other linkage subsystems to obtain the GIS location of the terminal, thereby realizing the GIS scheduling function.

[0018] The beneficial effects of the present invention are:

[0019] 1. Diversified communication methods: The mining three-dimensional fusion dispatching platform integrates multiple communication methods such as voice communication, data communication and video communication, which can meet the communication needs in different scenarios.

[0022] 4. Rapid response and rescue capabilities: When a coal mine accident occurs, the mining three-dimensional fusion dispatching platform can quickly respond and provide accurate location information for emergency rescue.

[0023] 5. Safety and reliability: Coal mines are dangerous working environments, so safety is the primary consideration for the three-dimensional fusion dispatching platform for mines. The system should have reliable fault diagnosis and recovery functions to ensure the stability and continuity of communication.

[0024] 6. Wide coverage: As the coal mine area is large, a communication system with wide coverage is required, which can achieve seamless coverage of the entire mine and meet the communication needs under various terrain and environmental conditions.

[0029] Figure 1 It is a structural schematic diagram of the three-dimensional fusion dispatching platform for mining of the present invention.

[0030] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0031] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0032] WiFi / 4G wireless communication systems are widely used in large-scale mines across the country, and the 5G and WiFi6 wireless converged communication systems newly invested in recent years are gradually maturing.

[0033] 4G wireless communication system:

[0034] The main functions of the 4G wireless communication system for mines are as follows: 1) Audio and video communication. Provide voice, video, SMS and other business communication functions. 2) Multimedia cluster dispatch. Support voice, video, SMS, data and other cluster dispatch services and real-time video and data return distribution functions, with group call, group call, forced insertion, forced removal, conference, recording and monitoring functions. 3) Video monitoring. Real-time video monitoring is achieved through underground cameras and mobile phone terminals. 4) Data transmission. Wireless transmission of monitoring and surveillance systems, personnel positioning systems and various sensor data.

[0035] The main advantages of the 4G wireless communication system for mines: 1) Flexible networking. 4G adopts a fully IP distributed structure with good integration. It can be integrated and coexist with different wireless technologies such as WiFi under the same architecture, and can be easily integrated with the wired network dispatching communication system using soft switching technology or IP-PBX switches to form a comprehensive dispatching communication system that integrates wired and wireless above and below the mine. 2) Wide coverage. The coverage radius of the ground base station in the mining area is not less than 5km, and the underground coverage range is 800m. It can adapt to networking of different scales, greatly reducing the number of base stations. 3) Mature technology and products. The stability and adaptability of the 4G system to the environment are constantly improving, and terminal equipment is relatively abundant.

[0036] The main disadvantage of the 4G wireless communication system for mining is that its bandwidth and real-time indicators cannot meet the requirements of application scenarios such as high-definition intelligent video and remote control.

[0037] 5G wireless communication system:

[0038] 5G can be applied in coal mines in the following scenarios: 1) Ultra-reliable, low-latency communication. Unmanned transportation, remote control of equipment, real-time monitoring of mobile devices, coal mine robot control, etc. 2) Enhanced mobile broadband. Underground video monitoring, voice communication, broadcast scheduling, smart terminals, virtual mine construction, mixed reality mining, etc. 3) Low cost, low energy consumption, and wide connection. Underground electronic fences, vehicle transportation management, smart wearable devices, safety system monitoring, operation safety monitoring, precise positioning of personnel, etc.

[0039] The promotion and use of 5G wireless communication systems for mines is still in its infancy. In terms of terminals, 5G mobile phones, mining CPE, etc. have obtained relevant coal safety certification and are ready for underground application. Mining products involving R16 NB-IoT have not yet completed coal safety certification.

[0040] 5G has the advantages of high transmission rate, low latency, strong concurrency and high reliability, but there are the following problems in actual use: 1) Safety issues of wireless transmission signals in the case of multiple systems and multiple antennas. According to GB 3836.1-2010 "Explosive Environment Part 1: General Requirements for Equipment", the transmission power of RF antennas in coal mine gas environment shall not exceed 6W, resulting in small wireless coverage, high equipment investment, and large installation and maintenance workload, which is not conducive to promotion. 2) 5G base stations are mainly explosion-proof and intrinsically safe, with large mass and volume, inconvenient to use and limited occasions. 3) The 5G terminal ecosystem is scarce, the communication module is expensive and power-hungry, and does not meet the conditions for large-scale industry application. 4) There are few actual application cases, and the application scenarios need to be further explored.

[0041] WiFi / WiFi6 wireless communication system:

[0042] At present, WiFi / WiFi6 wireless communication systems are mainly used in the following aspects: 1) Voice calls and voice dispatch. Including two-way calls, group calls, group calls, forced insertion, forced removal, conferences, recording and monitoring, etc. 2) Personnel positioning. Using information such as field strength and fingerprint features, the approximate location of the person holding the mobile phone can be determined. 3) Video transmission. One of the characteristics of WiFi is large bandwidth, which can achieve relatively low-cost video transmission with low latency requirements.

[0043] The WiFi6 wireless communication system has the advantages of simple structure, low cost, and high transmission rate, but the latency is relatively high, and the mobility and reliability are relatively low. In addition, the mobile phone terminals are relatively immature, which affects the quality of voice calls.

[0044] The present invention provides a three-dimensional fusion dispatching platform for mining, comprising a server and a client. The server communicates with the client, and the server is connected to other linkage subsystems, and is connected to core network services and outgoing services.

[0045] The server consists of four parts and is managed uniformly through Docker Compose, a tool for defining and running multi-container Docker applications. It uses a YAML-formatted configuration file (docker-compose.yml by default) to configure the application's services, including containers, networks, and volumes. Users can use this configuration file to declaratively define the dependencies between multiple containers, and then start or shut down these containers at the same time with a single command. This deployment in the form of containers greatly simplifies the deployment process of the three-dimensional fusion scheduling platform.

[0046] like Figure 1 As shown, the four parts of the server include a dispatch module (Dispatcher), a Sip service module (SipServer, based on freeswitch), a database module (Database), and a voice conversion module (MrcpServer).

[0047] Sip service module:

[0048] SipServer (based on freeswitch) serves as the foundation and core of voice communication, providing basic services such as sip account registration, session establishment and release, voice packet forwarding and recording, etc., to provide command and dispatch functions with multimedia cluster and audio and video consultation as the core. Through access gateway docking, it supports access to media and terminals of various networks, including video surveillance, conference terminals, wired phones, emergency broadcasts, 4G / 5G mobile phones, smart mining lamps, etc. At the same time, it also serves as the main connection part for docking 4G / 5G core network and outbound, and can realize unified dispatch with 4G / 5G core network and other communication systems.

[0049] Scheduling module:

[0050] Dispatcher is the dispatch backend, providing a restfull http interface to the outside world, and can be linked with other systems for business processing, including video surveillance systems, personnel positioning systems, etc., to realize core business functions such as video surveillance, video consultation, and GIS dispatch for the platform. In particular, for terminals that do not support the video call protocol in SipServer, they can be linked with the video surveillance system to realize the video call function through SIP voice + video streaming; they can communicate with SipServer in real time to realize unified dispatch control of the control and command center.

[0051] Database module:

[0052] As a database module, Database provides data access capabilities for SipServer and Dispatcher.

[0053] Voice conversion module:

[0054] MRCP server is a TTS module (Text-to-Speech), which converts text information into natural and fluent voice output and provides text-to-speech function. It interacts with sipserver through MRCP protocol to realize the scheduling function of text broadcasting for the three-dimensional fusion scheduling platform.

[0055] Client:

[0056] The client is implemented by QT (a cross-platform application development framework), which is a cross-platform graphical user interface application development framework that can build high-performance desktop, mobile and web applications. It monitors the entire dispatch system by communicating with the Dispatcher (http request and websocket).

[0057] Through the components of the above-mentioned dispatching platform, functions such as voice dispatching, video dispatching, GIS dispatching, cluster intercom, integrated conference, instant messaging, etc. can be realized. The usage process is that the terminal is connected to the freewitch-based SipServer, and communicates and interacts with the Dispatcher and the client in real time, which can realize voice dispatching, video dispatching, cluster intercom, integrated conference, instant messaging, etc. The Dispatcher can also be linked with other systems, such as the personnel positioning system, to obtain the GIS location of the terminal, thereby realizing the GIS dispatching function.

[0058] In summary, the above solutions can provide coal mines with more abundant services, including: voice / video calls, video monitoring, multimedia scheduling, multi-party conferences (voice, video), data transmission, underground mobile safety production management, etc. Its main functions include:

[0059] Achieve wireless WIFI / 4G signal coverage in key areas required underground, provide SIP-based high-definition voice, video calls, voice scheduling, data and other services, and realize data network services between mining 4G mobile phones and servers underground and on the ground.

[0060] By integrating the wireless communication system and the wired communication system resources through the fusion business switch, an integrated dispatching platform is formed, which effectively improves the communication level of the mine.

[0061] Dispatching function: support calling, group calling, forced insertion, forced removal, monitoring, recording, prohibition of calls, forced hanging and other functions;

[0062] Communication function: support VoLTE high-definition voice and video call functions;

[0063] Short message: For mobile terminals, the system has functions such as SMS sending and record query;

[0064] Call records: The system has call record query function;

[0065] Recording and query: The system has global recording and query, playback and download functions;

[0066] User authority management: Different user management authorities can be configured as needed;

[0067] Restriction function: The call terminals in the system can set the call permissions for each terminal, such as only certain terminals have the outgoing call permission function, and the rest do not have outgoing call permissions.

[0068] Call: Select the user you want to call, double-click the user or click the call button to call the selected user. The call starts after the called user answers. If the called user does not answer, the call ends automatically after the timeout. Users cannot call themselves.

[0069] Monitor: Select the user who is talking and click the monitor button to listen to the selected user's conversation. The monitored user cannot hear the monitor's voice. Low-level dispatchers cannot use this function on high-level users or dispatchers.

[0070] Force hang-up: The dispatcher can force hang-up two users who are on a call. Select any one of the users, or enter the number of any user and click the force hang-up button. Both parties will end the call immediately.

[0071] Forced disconnection: Select the user who is in a call and click the forced disconnection button to start a call with the selected user directly. The original caller with the selected user will be disconnected. Forced disconnection can be performed on users in idle, roaming, unknown and other states to establish a call between the dispatcher and the user. Low-level dispatchers cannot use this function on high-level users or dispatchers.

[0072] Forced Intrusion: After selecting a user who is on a call, click the Forced Intrusion button to insert into the selected user's call, forming a three-party call. Forced Intrusion can be performed on users in idle, roaming, unknown, etc., to establish a call between the dispatcher and the user. Low-level dispatchers cannot use this function on high-level users or dispatchers.

[0073] Dial pad: This area is specially prepared for calling external numbers of the system. You can use the soft dial pad to enter numbers to call external phones.

[0074] Recording: The real-time recording function can be enabled for any wired or wireless extension that needs recording. Every call is recorded in real time, and the recording files are stored in the dispatch machine or a dedicated recording file storage device. The management and query of the recordings can be completed through a dedicated external recording server, providing safer and more reliable management.

[0075] Unattended: When it is not working hours, you can set an unattended number to enable incoming calls to be directly transferred to another designated dispatch desk or internal phone (such as an IP phone or FXS user on night duty). After setting the unattended number, the unattended number button becomes the Cancel Unattended Number button, and the unattended number function will take effect; therefore, any calls to the dispatcher will be directly transferred to the unattended number extension, and the extension will ring.

[0076] Queue / hold function: The dispatcher's incoming calls can be queued, and the queue supports group answering; at the same time, the dispatcher can choose to hold and throw the user currently calling back to the queue.

[0077] Scheduling function:

[0078] 1) Virtual dispatching function: The entire dispatching system can be virtually divided into multiple independent dispatching systems, each of which undertakes different dispatching services;

[0079] 2) Soft keyboard: Direct dialing with keyboard, coordinated function operation, and the dispatcher can use the keyboard to assist in joining the device number that is not in the user status area;

[0080] 3) User status notification for the entire network: All authorized dispatchers in the network can obtain the status of terminal users on the network (calling, idle, online, offline, etc.) in real time;

[0081] 4) SMS function: The dispatching station can send SMS instructions to the wireless dispatching terminal, support SMS groups, and support internal users and public network users;

[0082] 5) Temporary conference: The dispatcher can add any queued user to the current call to hold a conference at any time;

[0083] 6) Meeting management: The dispatch console has built-in meeting management functions, which can invite meeting members, or perform operations such as muting, isolating, and kicking out participants;

[0084] 7) Unified network management: supports unified management of all dispatching machines, access terminals and other equipment, and can obtain equipment alarms, status and other information in real time;

[0085] 8) Group scheduling function: conference call, group call.

[0086] The video call method of SIP voice + video streaming proposed in the present invention can solve the video call problem of terminals that do not support the SIP video protocol in the mine, and provide a friendly and compatible implementation method for unified scheduling. The outgoing business based on SIP service can integrate the core network of other platforms and communication systems with different communication methods, solve the problem that traditional mines cannot uniformly manage various communication platforms, and can meet the requirements of relevant industry standards for wireless communication and various needs for scheduling applications in various professional fields of mines. The multi-network integration technology method can integrate multiple networks for underground wireless communication systems, emergency broadcast systems, video monitoring systems and other platforms, and realize the scheduling communication video linkage function. The intelligent scheduling and management platform supports voice scheduling, video scheduling, GIS scheduling, cluster intercom, integrated conference, instant messaging and other functions, realizing the integration of above-ground and underground communications, and the integration of wired and wireless scheduling, and improving scheduling and management efficiency.
