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.
