Description
Technical field
The present invention relates to the track traffic technical field, relate in particular to a kind of method and system of high efficiency of transmission station equipment status information.
Background technology
The station equipment status information network transmission efficiency that existing commercial systems for applications adopts is low.Because station equipment is numerous and equipment state changes frequently, cause each server end big in addition to status information of equipment data processing expense.Special when station centre simultaneously with stand in all devices can cause station centre's server to receive forwarding unit status data peak in short-term when establishing a communications link, and then influence the timely transmission of other business datum.
Below be the station equipment status information transmission solution that existing commercial systems for applications adopts:
1) when station centre's server and wire center server establish a communications link, station centre's server sends station equipment good working condition packet, packet of every equipment to the wire center server.
2) when equipment and station centre established a communications link, equipment sent to station centre's server with the good working condition of self.Station centre's server receives handles this equipment good working condition packet, and this packet is transmitted to the wire center server immediately.
3) when equipment state changes, equipment sends to station centre's server with the status data that changes.Station centre's server receives buffer memory equipment change status information.The every status information of equipment that will take place to change at a distance from N second (N is configurable) of station centre's server sends to the wire center server, packet of every Status Change equipment.
Table 1 is the status information of equipment data structure that station centre's server sends to the wire center server in the prior art:
Table 1
Wherein field 5,6 will circulate repeatedly, and cycle index is by field 4 definition.
There is following shortcoming in the station equipment status information transmission solution that aforesaid existing commercial systems for applications adopts:
(1) network transmission efficiency is low;
(2) station centre's server establishes a communications link with the wire center server and a large amount of station equipment is set up when communicating by letter with the station server simultaneously, and station centre's server transmitting apparatus state information data packet is too much, influences the timely transmission of other business datum;
(3) change when frequent when equipment state, station server transmitting apparatus state information data packet is too much, influences the timely transmission of other business datum;
(4) server end is big to status information of equipment data processing expense;
(5) server end produces the daily record of managing business of a large amount of status informations, takies a large amount of disk spaces, and makes log analysis and location of mistake become complicated.
Summary of the invention
To existing deficiency in the prior art, the object of the present invention is to provide a kind of method and system of high efficiency of transmission station equipment status information, to reduce server end to status information of equipment data processing expense; Going up the next central server establishes a communications link and device status data bag transmission peak no longer occurs in the process; Device status data bag transmission peak no longer appears when multiple devices frequently change state; Can reach newly-increased equipment state item by the newly-increased equipment of expansion very easily; Reduce the daily record output of managing business of server end status information, save the journal disk space, improve and make log analysis and location of mistake efficient.
