Problems solved by technology

[0003] At present, there are many signal system manufacturers, and the signal systems deployed by each manufacturer in different subways or lines are different. There is no unified standard real-time monitoring data interface, and the existing data interface cannot be used. Some signal systems carry out data interaction, and there is no unified data processing rule among the various systems, and they are also independent of each other, which consumes a lot of manpower and material resources when docking, and also makes it extremely difficult to share information between systems

Embodiment 1

[0025] Such as figure 1 As shown, the present embodiment discloses a method for real-time processing of multiple signals of urban rail transit, comprising the following steps:

[0026] S1. Connect with multiple traffic signal terminals, and generate a terminal identifier for each traffic signal terminal, where the terminal identifier is used to indicate the communication protocol used by the traffic signal terminal;

[0027] S2. Obtain signal data from the traffic signal terminal; the signal data includes terminal identification, data packet and target address information;

[0028] S3. Identify the communication protocol corresponding to the terminal identification, and use the data structure rules corresponding to the communication protocol to perform data processing on the data structure of the data packet, so that the data structure of the data packet conforms to the data specification of the communication protocol; the data structure includes a data frame header, data One...

Embodiment 2

[0042] Such as figure 2 As shown, this embodiment also corresponds to the method disclosed in Embodiment 1, and discloses a multi-signal real-time processing system for urban rail transit, including:

[0043] The system connection module 1 is used to connect with a plurality of traffic signal terminals, and generates a terminal identification for each traffic signal terminal, and the terminal identification is used to indicate the communication protocol used by the traffic signal terminal;

[0044] The data acquisition module 2 is used to acquire the signal data from the traffic signal terminal; the signal data includes terminal identification, data packet and target address information;

[0045] The data processing module 3 is used to identify the communication protocol corresponding to the terminal identification, and use the data structure rules corresponding to the communication protocol to perform data processing on the data structure of the data packet, so that the data...

Embodiment 3

[0056] Next, combine image 3 , a specific embodiment of the processing system disclosed in embodiment 2 is described:

[0057] Such as image 3 As shown, this embodiment discloses a multi-signal real-time processing system, including an adapter A connected to a data source A, an adapter B1 connected to a data source B, an adapter C1 connected to a data source C, and a central processing unit connected to the adapter system.

[0058] Specifically, it can be seen from the figure that one or more firewalls are set up between the data source and the adapter to perform data security checks, which improves the security of the system, and the central processing system uses multi-threading technology to provide signal data for each signal system. Separate threads are established for the processing of data, which makes full use of system resources and achieves the effect of efficient data processing.

Abstract

The invention discloses an urban rail transit multi-signal real-time processing method and system. Through a preset data processing rule, different types of signal data from a plurality of urban railtransit signal systems can be automatically processed and stored; when data needs to be processed subsequently, the data only needs to be directly called; when a sending command is received, the datais distributed to a target address; rapid jump of data in a complex network and equipment environment can be easily realized, the purpose of cross-network and cross-protocol flow of the data is achieved, information sharing and data interaction can be realized among a plurality of signal systems, the data transmission efficiency of the urban rail transit signal network is greatly improved, and workers do not need to manually connect or process the data.

Description

technical field [0001] The invention belongs to the field of urban rail transit signal processing, and in particular relates to a method and system for real-time processing of multi-signals of urban rail transit. Background technique [0002] The urban rail transit signal system is the key system equipment to ensure the safety of train operation, realize the modernization of traffic command and train operation, and improve transportation efficiency. It includes multiple complex signal systems that can control all aspects of urban rail transit. The unified management and data interaction of these signal systems form a very large data network, which determines the work efficiency of urban rail transit systems and is also related to traffic It is closely related to the normal operation of the system. [0003] At present, there are many signal system manufacturers, and the signal systems deployed by each manufacturer in different subways or lines are different. There is no unif...
