Description
Technical field
The present invention relates to track traffic control technology field, and in particular to a kind of application server operation element station communication
Method, system and operation element station.
Background technology
ATS (Automatic Train Supervision, train automatic monitoring system) is applied to track traffic control
In, the operation of train in the automatic supervision of realization, control line.The integrated multiple plug-in units in operation element station, the list of dispatching a car being responsible in ATS
Show and service chart shows.The reception and forwarding of subsystems data flow in ATS be responsible for by application server, and receive and locate
The operational order that each plug-in unit sends in reason operation element station.
The method that existing application server is communicated with operation element station is (as shown in Figure 1)：Application server 11 passes through
Configuration parameter sets up UDP (User Data Protocol, UDP) communications for each plug-in unit 12, and sets up WCF
(Windows Communication Foundation, Windows communication interfaces) communicates；Wherein, configuration parameter is stored in XML
In file, each plug-in unit has corresponding configuration parameter.WCF communication connections set up respectively by each plug-in unit 12 with application server 11
Afterwards, operation plan data are obtained, after internal data structure conversion, operation plan data is presented in plug-in interface.
After UDP communication connections set up respectively by each plug-in unit 12 with application server 11, the presence states number that other subsystems are produced is obtained
According to presence states are informed 12 interface of plug-in unit by data conversion through inside in real time.User is reflected according to 12 interface of plug-in unit
Presence states are operated, the UDP communication link sending and receiving that corresponding operational order is set up with application server 11 by the plug-in unit 12
Give application server 11 to process.
In the method that existing application server is communicated with operation element station, the communications burden weight of application server, and
Maintainable poor.Due to plug-in unit be all integrated into the multiple plug-in units in operation element station, and each operation element station respectively with
Communication set up by application server, and the amount of communication data which results in application server is larger, increased the logical of application server
Letter burden.Simultaneously as each plug-in unit being integrated in operation element station will be set up with application server respectively communicating, then
Just must be provided with corresponding configuration parameter to initialize communication, need the data volume of the configuration parameter for arranging to increase exponentially, cause
The maintainable reduction of ATS systems.
