Embodiment
In order to allow those skilled in the art can understand technical scheme of the present invention better, below in conjunction with accompanying drawing, the invention will be further elaborated.
Fig. 1 shows the schematic network structure of a kind of reliable distributed alarming method of the present invention, and Fig. 2 shows a kind of distributed alarming method data flow diagram reliably of the present invention; See Fig. 1, Fig. 2, present invention is disclosed a kind of distributed alarming method reliably, comprise the following steps:
1, alerter service unit receives the warning information from alarm source;
In an embodiment of the present invention, alerter service unit receives the warning information from alarm source, specifically comprises: by interface, alerter service unit judges whether alarm source produces warning information; If generation warning information, gathers warning information by interface.Wherein, alarm source comprises: a) alarm source of system platform, is mainly the system state data that alerter service unit is gathered by the interface of system itself; B) alarm source of system platform outside, when being positioned at system platform secondary development, the interface that other external systems integrated provide alarm to input; Alerter service unit can be warning Agent.
2, warning information is pushed to IceStorm server by alerter service unit;
In an embodiment of the present invention, IceStorm server comprises one or more stations IceStorm server, center IceStorm server; Alerter service unit comprises one or more stations alerter service unit, center alerter service unit; Wherein, station alerter service unit and center alerter service unit gather warning information respectively by respective interface, and are pushed to station IceStorm server and center IceStorm server respectively.
3, IceStorm server is according to client subscription request, and warning information is forwarded to client;
Concrete, client comprises station client, central station client; Wherein, station client sends subscribe request to station IceStorm server, central station client sends subscribe request to all stations IceStorm server, Ye Xiang center IceStorm server sends subscribe request simultaneously, after IceStorm server accepts the subscribe request of client, warning information is forwarded to client.
The process of subscribe request is as follows:
● issue flow process:
I. first publisher connects with the port of the request manager of IceStorm server, obtains the agency of manager;
Ii. by the agency of request manager, create the warning information that will issue or the warning information obtaining issue, obtain warning information agency;
Iii. by obtaining warning information agency, obtain the agency released news, this agency is corresponding with the port that the reception publisher of IceStorm server sends message.
● subscribe to flow process:
I. by the agency of request manager, create the warning information that will subscribe to or the warning information obtaining subscription, and obtain warning information agency;
Ii. open the listening port of the machine, by warning information, agency subscribes to this warning information.
This subscribe request process, publisher is alerter service unit, and subscriber is client, and warning information is acted on behalf of as the Object Request Broker in client and IceStorm server communication process; IceStorm server stores subscribing relationship, even if IceStorm Server Restart, this subscribing relationship still exists, and only has in time sending a message to subscriber, there is connection error, and will cancel subscriptions relation automatically, and arrange retry parameter.
In embodiments of the present invention, in order to solve warning information stationary problem, this alarm method also comprises:
A) when the success of client's side link alerter service unit, then to send a warning message synchronization request to alerter service unit;
It should be noted that, client's side link alerter service unit is in order to when system produces warning information, only has operator to carry out shutoff operation, just or after confirming this alarm can eliminate, otherwise the warning information of history also can show in the client; Under normal circumstances, acquisition two information are needed after client terminal start-up: the history alarm information 1) produced before client terminal start-up, 2) warning information that produces in real time after client terminal start-up; Due to the warning information that IceStorm server process is real-time, so history alarm information must obtain its history alarm information by connecting alerter service unit.
B) alerter service unit accepts synchronization request, and synchronous history alarm information is to client, and history alarm information exports and shows on interface by client;
C) when client and the connection failure of alerter service unit, then from database loading history warning information, export and show on interface.
In embodiments of the present invention, in order to solve, operational issue is carried out to warning information, this alarm method also comprises: after client receiving alarm information, client operates warning information, and to alerter service unit transmit operation information, alerter service unit more new database and by operation after warning information be sent to IceStorm server.
Concrete, client has the operation that warning information carries out: confirm warning information, close, add remarks etc., after complete operation, to alerter service unit transmit operation information, alerter service unit is responsible for more new database, then the warning information after change is sent to IceStorm server, according to the subscribe request of client, warning information after change is sent to relative client by IceStorm server, and client refreshes interface again.
In embodiments of the present invention, in order to prevent client and alerter service unit disconnecting problem, the present invention also comprises: client timing sends heartbeat message to alerter service unit, when client can not receive the heartbeat response message of alerter service unit, then think client and alerter service unit disconnecting, client sends connection request to alerter service unit again.
Concrete, when after client and the successful connection of alerter service unit, client to send a warning message synchronization request to alerter service unit again.
After alerter service unit receives warning information, alert program unit automatic trigger alerts prediction scheme program;
It should be noted that, in distributed alarm system, the prediction scheme program that configurable report alarming information correspondence one is pre-configured; So-called prediction scheme, exactly for one group of automatic operation action that Mechatronic Systems or the warning system itself of management are carried out; The operation of automatic trigger alerts prediction scheme program when producing when reporting to the police, as when breaking out of fire is reported to the police, warning information is configured with automatic prediction scheme program, and its prediction scheme program comprises the following steps:
● judge fire location;
● send order to environmental control system, control blower fan and dry to assigned direction, avoid smog to injure passenger;
● send order to broadcast system, play the urgent broadcast notice preset;
● send order to ticket sale system, control gate and open, facilitate passenger evacuation;
● emergency release gate control system.
