Embodiment Construction

[0058] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0059] Existing existing passenger message system mostly adopts the communication based on Socket (socket word) mode to realize message distribution. Socket (socket) can be regarded as an abstraction layer through which applications send and receive data. Using Socket, applications can be added to the network and communicate with other applications in the same network. To put it simply, Socket provides a port for communication between the program and the outside world and provides a data transmission channel for both parties to c...

Abstract

The invention provides a passenger information system message distribution method and device and a passenger information system. The method comprises the following steps: receiving an issuing messagefrom a central management device of a passenger information system, carrying out first preprocessing on the issuing message to obtain an issuing message packet, and sending the issuing message packetto message queue middleware; enabling the message queue middleware to obtain the theme of the issued message and publishes the issued message packet to a target message queue according to the theme ofthe issued message, wherein the target message queue comprises a message queue corresponding to the theme; and sending the issued message packet in the message queue of the message queue middleware to a corresponding target receiving device according to a preset subscription theme of the receiving device. The central management device, the message queue middleware and the receiving device are separated and independent in three layers, coupling of the central management device and the receiving device is reduced, and stability of the whole system is guaranteed. The high availability of the message queue middleware can ensure the integrity of the data.

Description

technical field [0001] The invention relates to the technical field of rail transit, more specifically, to a passenger information system message distribution method and device in a passenger information system and a passenger information system. Background technique [0002] The passenger information system (PIS for short) is a system commonly used in the modern urban rail transit industry to provide passengers with diversified multimedia information services. For example, train operation information, network operation information, convenience information or emergency evacuation information can be provided through the passenger information system. A typical passenger information system may include parts related to an operating control center (OCC), a station subsystem, an onboard subsystem, a network subsystem, and the like. Functions such as media design, multimedia editing and broadcasting management, equipment playback monitoring, and external interface are realized by ...
