Embodiment Construction

[0020] In order to further illustrate the features of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. The accompanying drawings are for reference and description only, and are not intended to limit the protection scope of the present invention.

[0021] Such as figure 1 As shown, the present embodiment discloses a RSSP-II communication method based on UDP communication, comprising the steps of:

[0022] S1, numbering the events in the UDP communication process, and identifying and simulating the events in the UDP communication process by numbering;

[0023] S2. Use the simulated event to trigger the conversion of the UDP state machine, and obtain the current conversion state of the UDP state machine;

[0024] S3. The RSSP-II protocol stack acquires the conversion state of the UDP state machine by calling the corresponding interface function provided by the network adaptation layer, and manages the ...

Abstract

The invention discloses an RSSP-II communication method based on UDP communication, and belongs to the technical field of communications. The RSSP-II communication method comprises the following steps: numbering events in a UDP communication process, and simulating the events in the UDP communication process by identifying the numbers; using the simulated events to trigger the conversion of a UDPstate machine, and obtaining the current conversion state of the UDP state machine; and acquiring the conversion state of the UDP state machine by an RSSP-II protocol stack by calling a correspondinginterface function provided by a network adaptive layer, and managing the UDP state machine. According to the RSSP-II communication method based on the UDP communication provided by the invention, theRSSP-II protocol stack regards the UDP as the equivalent connection with the TCP, so that an RSSP-II protocol is not only applicable to equipment using a TCP mode to communicate, but also applicableto equipment using a UDP mode to communicate, so that the generality of the RSSP-II protocol is greatly improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an RSSP-II communication method based on UDP communication. Background technique [0002] The RSSP-II safety communication protocol is a protocol used for communication between railway signaling equipment, and its safety integrity level can reach SIL4. At present, the existing RSSP-II protocol is based on TCP communication, but some railway signaling devices use UDP to communicate, and the TCP-based RSSP-II protocol cannot be applied between these devices. Contents of the invention [0003] The purpose of the present invention is to provide a kind of RSSP-II communication method based on UDP communication, to improve the versatility of RSSP-II protocol. [0004] For realizing above object, the technical scheme that the present invention adopts is: a kind of RSSP-II communication method based on UDP communication is provided, comprising: [0005] Number the events in the...
