The invention discloses a reliable distributed alarm system and method. The system includes an alarm service program unit, an IceStorm server and a client; the method includes that the alarm service program unit receives alarm information from an alarm source; the alarm service program unit pushes the alarm information To the IceStorm server; the IceStorm server forwards the alarm information to the client according to the subscription request of the client. The present invention subscribes the alarm information to the IceStorm server through the client, and the central station client can directly communicate with stations on different lines and synchronize the alarms of the stations; when the central station and the station are offline, the station can independently manage the alarms of the station Information; the distributed alarm system can add stations or central stations at any time to realize the vertical and horizontal expansion of the alarm system.
Description
technical field [0001] The invention relates to the field of vehicle management, in particular to a reliable distributed alarm system and method. Background technique [0002] The current subway alarm system usually adopts a centralized and hierarchical alarm system. For the centralized alarm system, each subway station can independently display the alarm data of the station, but when the central server and the station are offline, the station cannot work normally; For a layered alarm system, the station generates an alarm and uploads it to the central server for unified management, which will increase the operating pressure of the central server. At the same time, the repetition of multi-layer communication operations is not conducive to system expansion. Contents of the invention [0003] In order to solve the problems in the above-mentioned existing alarm system that the station cannot independently manage the alarm data of the station due to the off-line of the station...
