Description

Technical Field

[0001] The invention relates to an adaptive single-port multi-protocol railway integrated video monitoring method, system and readable medium, belonging to the technical field of video monitoring processing. Background Art

[0002] Railway integrated video surveillance system is a monitoring system that meets the needs of railway traffic command, production organization, passenger service, operation monitoring, emergency rescue and public security prevention. It uses audio and video monitoring, communication, computer network, cloud computing, cloud storage and other technologies, combined with intelligent analysis technology, and has the functions of audio and video line-of-sight acquisition, transmission, control, display, storage and processing. With the increasing development of my country's high-speed railways, the video surveillance system has gradually expanded its application in the fields of high-speed railway transportation command, production operation, operation management, public security maintenance, etc., and has become a key scientific and technological guarantee for high-speed railway safety production, efficiency improvement and management strengthening.

[0003] The railway integrated video system adopts a three-level architecture of access nodes, regional nodes, and core nodes to achieve unified monitoring and dispatching of national railway video resources. The overall logical architecture is as follows: Figure 1 As shown. In order to standardize the design, implementation, inspection and testing, and operation and maintenance management of railway integrated video surveillance systems, a series of specifications and signaling standards have been promulgated since 2008: On November 19, 2008, the former Ministry of Railways Transportation Bureau promulgated the "Technical Specifications for Railway Integrated Video Surveillance Systems (Trial)" (Yunji Communication

[2008] No. 630, referred to as Document No. 630). On June 29, 2013, the former China Railway Corporation promulgated the "Technical Specifications for Railway Integrated Video Surveillance Systems (V1.0)" (Tiezongyun

[2013] No. 71, referred to as Document No. 71). On August 3, 2017, the former China Railway Corporation promulgated Q / CR575-2017 "Technical Specifications for Railway Integrated Video Surveillance Systems", referred to as Q / CR575-2017. On August 15, 2022, the China Railway Group issued Q / CR575-2022 "Technical Specifications for Railway Integrated Video Surveillance Systems", which is the first revision after the first promulgation in 2017, referred to as Q / CR575-2022. The signaling standard protocol of Document No. 71 and the signaling standard of Q / CR575-2017 represent two different versions of the railway signaling system. For the convenience of expression, the signaling standard specified in Document No. 71 is referred to as TB1.0, and the signaling standard specified in Q / CR575-2017 is referred to as TB2.0. Q / CR575-2022 stipulates full support for GB28181 standard (2011, 2016, 2022) and GBT35114 standard (2017).

[0004] In summary, the current three-level architecture system of the railway integrated video surveillance system needs to be compatible with node platforms that follow six signaling standards: TB1.0, TB2.0, GB28181-2011, GB28181-2016, GB28181-2022, and GBT35114-2017.

[0005] In the three-level architecture of the current railway integrated video surveillance system, the commonly used multi-signaling protocol solution is Figure 2 In this three-level architecture system, both core nodes and regional nodes need to be compatible with all protocol standards. Figure 2 Each box with a protocol name represents the system's port monitoring and signaling processing for this protocol. Each protocol is independent of each other, and the access node can select a certain protocol to connect to the regional node. The problem with this structure is that the operation and maintenance personnel of systems at all levels must be very clear about which ports correspond to various protocols, which ports are needed for the upper system, and which port is needed for the lower system to receive. Furthermore, complex configurations are required for these ports, which greatly increases the complexity of system operation and maintenance and engineering deployment. Summary of the invention

In the description of the present invention, it should be understood that the terms used are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0021] In order to solve the problems existing in the prior art, the operation and maintenance personnel of systems at all levels must be very clear about which ports correspond to various protocols, which ports are needed for the upper system, and which ports are needed for the lower system to receive, and then it is necessary to perform complex configurations for these ports, which greatly increases the complexity of system operation and maintenance and engineering deployment. The present invention proposes an adaptive single-port multi-protocol railway integrated video monitoring method, system and readable medium. The core nodes, regional nodes and access nodes all adopt a single-port adaptive multi-protocol platform, which can meet the docking of devices or platforms of various protocols at various levels, and build a complete three-level architecture of the railway integrated video monitoring system. It can be seen that the core of the present invention is the internal implementation framework logic of the single-port adaptive multi-protocol platform. It solves the problems of the existing multi-protocol multi-port architecture, realizes adaptive single-port multi-protocol railway integrated video monitoring, reduces the difficulty of system operation and maintenance, deployment, and configuration management, improves the efficiency of software version management, and simplifies the difficulty of system docking and debugging. The scheme of the present invention is described in detail below through embodiments.

[0024] S3 determines which protocol the signaling in the signaling channel belongs to, and sends it to the processing module of the corresponding protocol; The method for determining which protocol the signaling in the signaling channel belongs to is to detect and analyze the registration signaling in the established signaling channel to determine the protocol system it belongs to. Specifically, the protocol is determined to be a national standard or a railway standard system based on the difference in the registration signaling of the protocol, and then the protocols of each system and version are further distinguished based on other signaling. After multiple levels of judgment, it is determined which protocol the signaling belongs to.

[0025] S4: If there are multiple versions of the protocol, determine the version of the signaling protocol and send it to the processing module corresponding to the protocol version; The method for determining the version of the signaling protocol is: in a certain protocol system, always detect whether there is characteristic signaling in the signaling that marks the protocol version characteristics.
