The data access layer module is used for receiving and transmitting data interfaces with an operating system, managing the receiving of TCP, UDP, RS485, RS422 and CAN data and forwarding the data which needs to be sent by an upper layer. The data access layer module is internally provided with a network monitoring unit, the network monitoring unit records data received and forwarded by the CAN, the RS422 and the RS485, and captures TCP and UDP data packets through detection of the IP layer.
The safety communication protocol conversion layer module integrates a railway signal safety communication protocol-I (namely RSSP-I), a railway signal safety communication protocol-II (namely RSSP-II), a SAHARA safety protocol and a plurality of enterprise internal private safety communication protocols, and removes the safety communication protocol encapsulation for the received data or carries out the safety communication protocol encapsulation for the data which needs to be sent and is not encapsulated according to the preset in the configuration file.
The application protocol conversion layer module is used for the interconversion between the internal application protocol of the enterprise and the interconnection GAL layer protocol, and can also be used for the interconversion between the new and old application layer protocols of different versions.
After receiving the application data, the forwarding control layer module analyzes the source address and the destination address in the data packet, then inquires the forwarding control table to mark the received data according to different communication cycles, different communication links, which kind of secure communication protocol is used, and the like, and sends the marked data to a lower layer for packaging and sending.
The rail transit signal system simulation interface management server of the embodiment accomplishes the following functions: (1) signal equipment access management based on the configuration file; (2) signal equipment data forwarding based on the configuration file; (3) the switching function with a plurality of secure communication protocols; (4) service data can be repackaged according to configuration; and (5) recording data forwarded by the simulation interface management server.
The respective functions described above are described in detail below.
(1) And (3) signal equipment access management based on the configuration file:
the forwarding control layer module of the emulation interface management server in this embodiment updates the device management list in the forwarding control layer module by reading the device configuration file when restarting, where the device management list includes, but is not limited to, the type, serial number, ID, interconnection ID, which secure communication protocol is used, the communication IP and port, the link layer protocol type, whether the service protocol needs to be converted, and the service protocol conversion configuration file link.
All signal devices in the simulation laboratory only need one external communication port to be connected with the simulation interface management server, the external communication port is connected with the simulation interface management server port appointed in the configuration file through TCP, UDP, CAN, RS422 and RS485, data is sent to the simulation interface management server when the service is needed, and when a certain signal device is not configured in the access configuration, the simulation interface management server discards all data transmitted by the signal device.
When signal devices are required to be added or reduced, only a certain signal device or certain signal devices are required to be added or deleted in the device configuration file of the simulation interface management server.
(2) Configuration file based signaling device data forwarding
The forwarding control layer module of the simulation interface management server analyzes the received service data to obtain the ID (or interconnection ID, etc.) of the destination device of the service data, searches the corresponding forwarding attribute (such as what kind of secure communication protocol is used, communication IP and port, link layer protocol type, whether the service protocol needs to be converted, service protocol conversion configuration file link, etc.) by searching the device management list, and informs the application protocol conversion layer module and the secure communication protocol conversion layer module to package the data according to the specified attribute according to the obtained attribute. The encapsulated data packet is then sent by the data access layer module to the destination.
(3) Switching function with multiple safety communication protocols
The device configuration file loaded by the simulation interface management server is provided with a configuration address of what secure communication protocol and protocol parameter each signal device has when being accessed, and what secure communication protocol each signal device has when being received and a configuration file link on the simulation interface management server. When a data packet of a certain signal device is transmitted into the simulation interface management server, the secure communication protocol conversion layer module of the simulation interface management server checks the data packet, and if the data packet is legal, the application data in the data packet is transmitted to the application protocol conversion layer module; and if the data packet is not verified legally, directly discarding the data packet.
When the simulation interface management server sends data to the signal device, the secure communication protocol conversion layer module determines which configuration is loaded to package the application data by adopting the secure communication protocol processing component according to the package protocol type and the configuration file link input by the forwarding control layer module.
When the safety communication protocol conversion layer module does not receive the forwarding data, the simulation interface management server can always maintain the safety connection with a certain device by configuring the device configuration file.
(4) Repackaging business data according to configuration
Since some signal devices (simulation devices or real devices) of old versions exist in the simulation system or when a new signal device is developed, other related systems are not modified, which requires the simulation interface management server to reassemble the service data as a temporary debugging means.
The simulation interface management server searches the service protocol conversion configuration file link in the equipment management list, and realizes the compatibility of application protocols of different versions by loading the service protocol conversion configuration of different interfaces, analyzing and re-packaging the service data to be forwarded through a universal protocol packaging module.
(5) Recording data forwarded by a management server via an emulation interface
The data access layer module of the simulation interface management server manages the receiving and sending of TCP, UDP, RS485, RS422 and CAN data through a receiving and sending interface with an operating system, and is also internally provided with a network monitoring unit which records the data received and forwarded by the CAN, RS422 and RS485 and captures and records TCP and UDP data packets through the detection of an IP layer.
The simulation interface management server is convenient for research personnel to correct and time-effect and detect the data receiving and sending performance of the signal equipment by recording the received and forwarded data in real time, and timely searches and solves the problems.
