In summary, existing traffic emergency command and dispatch platforms suffer from low efficiency in emergency command and coordination and low emergency response capabilities. Summary of the Invention

[0003] In view of this, it is necessary to provide an emergency command and dispatch system based on multi-source fusion communication to solve the technical problems of low emergency command and coordination efficiency and low emergency response capability of existing traffic emergency command and dispatch platforms.

[0005] Unified communication system platform;

[0006] The IP intercom and converged dispatch platform is connected to the converged communication system platform and is used to send intercom information or dispatch instructions to desktop video terminals and vehicle terminals through the converged communication system platform.

[0014] In one possible implementation, the cloud PBX platform is connected to the IP intercom and converged dispatch platform, desktop video terminals, vehicle terminals, and command terminals via a gateway for intercepting internal microservices.

[0015] In one possible implementation, the cloud PBX platform is also used to maintain sessions with the IP intercom and converged dispatch platform, desktop video terminals, vehicle terminals and command terminals through nginx reverse proxy, and to forward the web services of the IP intercom and converged dispatch platform, desktop video terminals, vehicle terminals and command terminals based on the gateway to realize the circuit breaking of web services, and to realize the functions of web service rate limiting, permission authentication and node upgrade based on the gateway.

[0016] In one possible implementation, the cloud PBX platform comprises multiple servers, which are deployed in a distributed manner through the Nacos middleware.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] This invention provides an emergency command and dispatch system based on multi-source fusion communication, which will be described in detail below.

[0032] As shown in Figure 1, the present invention provides an emergency command and dispatch system based on multi-source fusion communication, comprising:

[0033] Unified Communication System Platform 102;

[0034] IP intercom and converged dispatch platform 101 is connected to converged communication system platform 102 and is used to send intercom information or dispatch instructions to desktop video terminal 103 and vehicle terminal 104 through converged communication system platform 102.

[0035] Desktop video terminal 103 is used to send live video information to IP intercom and converged dispatch platform 101, vehicle terminal 104 and command terminal 105;

[0036] The vehicle-mounted terminal 104 is used to receive and display intercom information, dispatch instructions, or live video information;

[0037] The command terminal 105 communicates with the vehicle-mounted terminal 104 via the operator base station 107, and is used to send intercom information or dispatch instructions to the vehicle-mounted terminal 104.

[0038] Understandably, in this embodiment, a converged communication system platform 102 is deployed in the central computer room, establishing peer-to-peer relays with the IP intercom system and the converged dispatch system to achieve two-way communication and converged dispatch. Desktop video terminals 103 are deployed in each duty room or leader's office, and each terminal accesses the central platform via the enterprise internet. Vehicle-mounted mobile communication equipment is deployed on the high-speed inspection vehicle, and an emergency command box is deployed on the communication command vehicle. The vehicle-mounted terminal 104 can access the central platform via the operator's 4G / 5G network under mobile conditions. When performing emergency tasks, a temporary command post can be quickly set up, and local audio and video can be transmitted back to the command center, forming a four-in-one linkage emergency command pattern of the task site, temporary command post, dispatch center, and leader's desktop. At the same time, it seamlessly connects with the IP intercom system and the converged dispatch system to form a multi-terminal converged communication system.

[0039] By deploying video terminals on vehicles, the system features rapid emergency response, flexible mobile deployment, and multi-terminal linkage and collaboration, achieving the effects of flattened command and visualized communication, and providing strong support for leadership decision-making and deployment.

[0040] The project aims to create a new type of emergency command application, enabling comprehensive situational awareness on highways. Through on-site video imaging, it provides real-time updates on people, vehicles, roads, bridges, and other elements, effectively ensuring road traffic safety and smooth flow.

[0041] The emergency command and dispatch system based on multi-source fusion communication provided by this invention has the following beneficial effects:

[0042] 1) It has realized a provincial-level centralized monitoring and command management platform for highways, as well as an information system with GIS graphical display, multi-type multimedia access, and dedicated platform-based management;

[0043] 2) Establish a flat, integrated command system that enables vertical and horizontal coordination and efficient operation;

[0044] 3) Provide comprehensive, full-process, and 24 / 7 communication support for emergency response;

[0045] 4) Achieve full integration of voice, video, data, GIS positioning, instant messaging and other services.

[0046] 5) A monitoring and sensing system, a communication support system, and a real-time forecasting and early warning system that meet the requirements of modern intelligent highways have been established.

[0047] In some embodiments, the IP intercom and converged dispatch platform 101, the desktop video terminal 103, the vehicle terminal 104, and the command terminal 105 are also connected to the cloud PBX platform.

[0048] The cloud PBX platform is used to receive service requests uploaded by the IP intercom and integrated dispatch platform 101, desktop video terminal 103, vehicle terminal 104 and command terminal 105, process the service requests, and feed back the processing results to the corresponding platform or terminal.

[0049] In some embodiments, the cloud PBX platform is also used to provide web services to the IP intercom and converged dispatch platform 101, desktop video terminal 103, vehicle terminal 104 and command terminal 105, so as to receive business requests based on web services.

[0050] In some embodiments, the cloud PBX platform is also used to receive microservice registration requests sent by the IP intercom and converged dispatch platform 101, desktop video terminal 103, vehicle terminal 104 and command terminal 105, register microservices based on the microservice registration requests, and monitor the status of the IP intercom and converged dispatch platform 101, desktop video terminal 103, vehicle terminal 104 and command terminal 105 based on the microservices.

[0051] In some embodiments, the cloud PBX platform is provided with a gateway for intercepting internal microservices between itself and the IP intercom and converged dispatch platform 101, desktop video terminal 103, vehicle terminal 104 and command terminal 105.

[0052] In some embodiments, the cloud PBX platform is also used to maintain sessions with the IP intercom and converged dispatch platform 101, desktop video terminal 103, vehicle terminal 104 and command terminal 105 through nginx reverse proxy, and to forward the web services of the IP intercom and converged dispatch platform 101, desktop video terminal 103, vehicle terminal 104 and command terminal 105 based on the gateway, so as to realize the circuit breaking of web services, and to realize the functions of web service rate limiting, permission authentication and node upgrade based on the gateway.

[0053] It is understood that the emergency command and dispatch system based on multi-source fusion communication provided by this invention adopts a lightweight IMS platform of cloud PBX, which has high reliability, stability, and high compatibility. It can connect to mainstream voice devices on the market and supports deployment in user private clouds or public clouds, showing good platform compatibility. The platform adopts a microservice architecture, supports virtualization deployment, has strong scalability, and supports multi-domain isolation and multi-tenant sharing, resulting in high resource utilization. Each customer can be provided with independent usage space, isolated from each other, without affecting their own use, meeting operational needs.

[0054] The core of the entire system is the cloud-based platform, providing core switching and service implementation. It integrates multiple service modules such as IPPBX, SBC, address book, recording, billing, resource management, and automated operation and maintenance. Through cloud-based SaaS (Software as a Service), it provides enterprise users with IPPBX business functions such as internal voice communication, while also customizing for industry-specific needs, facilitating rapid implementation. Centralized cloud deployment and operation and maintenance avoid problems caused by limited personnel skills at the grassroots level, while saving maintenance and management costs. The Cloud PBX platform fully supports access to a full range of terminals, including IP phones, IP video phones, converged gateways, call centers, PBXs, and IADs, meeting the flexible networking needs of different users.

[0055] The cloud PBX system architecture is divided into five layers, as shown in Figure 2, which can flexibly provide different services:

[0056] manage:

[0057] Provides web services for IPPBX management;

[0058] Business layer:

[0059] BasicAS: Business analysis and processing, external call routing, etc.;

[0060] I-SBC: Registered Relay Edge Session Controller, providing registration functionality to other switching networks;

[0061] User data:

[0062] CDB: Central Database, providing MySQL and Redis database services, storing user and configuration data.

[0063] DNS: Provides DNS query services for network elements and has certain load balancing functions;

[0064] MRFS: Provides a distributed file system for managing files such as recordings and playbacks;

[0065] Session control:

[0066] MS: Media Server, which performs media-related processing;

[0067] CSCF: Accepts and forwards registration, call, and other requests;

[0068] Access and bearer:

[0069] SBC: Accepts and forwards registration, call and other requests, hiding the network topology of the IPPBX from the user;

[0070] Extended modules:

[0071] OMS Operation and Maintenance Management Components: A unified entry point for status monitoring and business management;

[0072] BAS Business Activation Component: Used to interface with external business systems (such as asset management, BOSS) to enable automatic account business activation;

[0073] CDRS Call Detail Record Management Component: Adopting a B / S architecture, it realizes functions such as call detail record management, centralized billing, access control, and service statistics.

[0074] In some embodiments, the cloud PBX platform includes multiple servers, which are deployed in a distributed manner through the Nacos middleware.

[0075] In some embodiments, multiple servers call each other through the Feign component and destructure via a message queue.

[0076] In some embodiments, the IP intercom and converged dispatch platform 101 is connected to the converged communication system platform 102 via an intranet.

[0077] In some embodiments, the desktop video terminal 103 and the converged communication system platform 102 are both connected to the vehicle terminal 104 and the command terminal 105 via the firewall 106.

[0078] As shown in Figure 3, the technical approach of the emergency command and dispatch system based on multi-source fusion communication provided by the present invention is as follows:

[0079] 1) Registration Center: Microservices of the Spring Cloud Alibaba Nacos business system are uniformly registered to the Nacos registration center for unified management, and the registration center monitors the service status.

[0080] 2) Gateway: Spring Cloud Gateway provides unified gateway interception to prevent internal microservices from being directly exposed and performs authentication and authorization at the gateway layer.

[0081] 3) Circuit breaking and rate limiting: Spring Cloud Alibaba Sentinel uses Sentinel for traffic control and reduces unstable resources in the call chain.

[0082] 4) Distributed Transactions: Spring Cloud Alibaba Seata uses Seata for distributed transaction processing of cross-service calls.

[0083] 5) Service calls: OpenFeign uses OpenFeign to make cross-service calls.

[0084] Authentication and Authorization: Spring Security + OAuth2.0. OAuth2 is actually a network standard for authorization. Spring Cloud implements OAuth2 in accordance with the standard and combines it with spring-security to create a specific implementation, which is mainly used for user authentication and authorization.

[0085] As shown in Figure 4, the implementation method of the emergency command and dispatch system based on multi-source fusion communication provided by the present invention is as follows:

[0086] (1) Presentation layer:

[0087] The presentation layer primarily displays information from user terminals (computer terminals, mobile applications, large screens). Communication between the client and server is initiated using the HTTP protocol, while the WebSocket protocol addresses full-duplex communication between the server and client. A RESTful design style web service is employed to process resource information for end users.

[0088] (2) Session layer:

[0089] The session layer primarily reflects the request path from the user terminal to the corresponding resource service. When a user terminal initiates a resource request, the session is maintained through an nginx reverse proxy, and then the service is forwarded through the Spring Cloud Gateway to achieve comprehensive use of gateway functions such as service circuit breaking, service rate limiting, authorization authentication, and trial operation of upgrade nodes.

[0090] (3) Business layer:

[0091] The business layer is mainly based on a microservice architecture pattern using the Spring Boot development framework, and mainly includes functional modules such as service bus, inter-service communication, and service / system governance.

[0092] The service bus is a service center formed by distributed deployment through Nacos middleware. It integrates and registers the services of various application businesses into one, allowing each business application's own client and other related business applications to call the services.

[0093] Inter-service communication can be achieved through two main methods: first, proactive and timely invocation between services via Feign; and second, by using message queues (RabbitMQ, Kafka) to help business systems deconstruct and improve development efficiency and system stability.

[0094] The main functions of service / system governance are to manage services (Admin Server, Turbine), circuit breaking and flow control and service link tracing (Hystrix, ZipKin, Sleuth), log collection, management, analysis and query (FileBeat, ELK, Elasticsearch), and server (Zabbix) application monitoring.

[0095] (4) Data layer:

[0096] The data layer mainly involves two modes: cached data storage (Redis) and persistent data storage (MySQL, Oracle, HBase, Hive).

[0097] Redis is primarily used to store frequently accessed data in Redis, which can then be retrieved directly from memory when needed, greatly improving speed and saving server overhead.

[0098] Relational databases such as MySQL and Oracle are mainly used for storing information within various business systems; HBase and Hive are used in big data centers. HBase is a database suitable for storing unstructured data and mainly solves the problem of real-time data querying, while Hive is used for data extraction, transformation, and loading, mainly solving the problem of data processing and computation.

[0099] (5) Continuous Integration:

[0100] Continuous Integration (CI) is a software development practice that uses automated builds (including compilation, deployment, and automated testing) to verify errors in the integration process. It is primarily used for the continuous and automated building and testing of software projects. Jenkin is an open-source CI tool with a user-friendly interface. Docker allows developers to package their applications and dependencies into a lightweight, portable container, which can then be deployed to any popular Linux machine, effectively achieving virtualization.

[0101] Those skilled in the art will understand that all or part of the processes of the methods described in the above embodiments can be implemented by a computer program instructing related hardware, and the program can be stored in a computer-readable storage medium. The computer-readable storage medium may be a disk, optical disk, read-only memory, or random access memory, etc.

[0102] The above provides a detailed description of the emergency command and dispatch system based on multi-source fusion communication provided by the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
