As shown in fig. 2, the CTC system includes a scheduling system, a database system, an application server system, and a communication server. The scheduling system comprises a scheduling terminal, a scheduling command module, a terminal program module, a; the database system is used for storing critical data, such as a basic diagram, a day shift plan, a phase plan, an actual track operation diagram, train formation information, signal display information, signal equipment state information and the like of train operation; the communication server completes data exchange between the central subsystem and the station subsystem; the application server system comprises a plurality of application servers which are core equipment of the dispatching centralized system, the plurality of application servers comprise one or more application servers of a real-time data processing server, a running chart and dispatching command processing server and a comprehensive information processing server, and each application server only processes data of types corresponding to the application server.
As shown, the schedule command data, the operation diagram data, the site diagram display and control data are transmitted between the schedule station terminal and the application server, and the application server implements interaction of various types of data with the database server and the communication server of the database system.
The application server system transmits data with the scheduling system, the database system and/or the communication server through ports such as the receiving module and the sending module, receives various types of data and processes the data through the data processing module. The present invention is described by taking three types of data (real-time type data, operation diagram, scheduling command data, and general information data) as an example, but is not limited to the three types of data indicated by the exemplary description of the present invention, and is not limited to three types of data systems, and two, four, and more than four other types of data systems can implement the present invention.
As shown in fig. 2, the application server a, the application server B, and the application server C are all application servers, but receive and process different types of data. Without loss of generality, for example, the application server a interacts with the site map display and control in the dispatcher station terminal for a first type of data, the application server B interacts with the dispatch command and operation map for a second type of data, and the application server C interacts with the query module for a third type of data.
As shown in fig. 3, a plurality of communication servers 1-N are associated with a plurality of stations, and each communication server is associated with a real-time data processing server, a travel diagram and scheduling command processing server, an integrated information processing server, and each scheduling station is also associated with the above-mentioned real-time data processing server, the travel diagram and scheduling command processing server, the integrated information processing server. One set of application server preferably has a processing range not exceeding three dispatching stations, but not limited to three dispatching stations; a set of application servers can process the railway line within 500 kilometers, but the scope of the railway line is not limited to be within 500 kilometers.
For convenience, the application server a is described by taking a real-time data processing application server as an example, the application server B is described by taking an operation diagram and a scheduling command processing application server as an example, and the application server C is described by taking an integrated information processing application server as an example. It should be noted that the present invention includes, but is not limited to, the enumerated application servers.
The real-time data processing application server receives real-time type data;
the operation diagram and scheduling command processing application server receives operation diagram and scheduling command data;
the integrated information processing application server receives integrated information data.
Different types of data can be distributed to the respective application servers in several ways:
the first method is as follows: the data are distinguished and forwarded, for example, the terminal of the dispatching desk sends all types of data to the data distribution equipment, and the data distribution equipment undertakes data distinguishing and sends the data to the corresponding application server.
The data type can be distinguished by a separate data distribution device. This way the discrimination flow is transferred to the data distribution device. After receiving data from a scheduling system, a database system and/or a communication server (such as a TDMS interface server, a railway head office interface server, a neighbor center interface server, etc.), the data distribution device analyzes the received data, and determines the type of the data according to the type code field in the data frame: the data processing system comprises real-time type data, operation diagram and scheduling command type data and comprehensive type data, and sends the data to corresponding application servers according to the data types, for example, the real-time type data is sent to a real-time data processing application server, the operation diagram and scheduling command data are sent to an operation diagram and scheduling command processing application server, and the comprehensive information data is sent to a comprehensive information processing application server. After each application server receives the data of the corresponding type, the data is processed through the data processing module of the application server.
The second method comprises the following steps: for the differentiation of the data types, the respective application servers can filter themselves by means of corresponding differentiation means. After the application server receives the data, the data type of the data is judged through a corresponding component, such as a data distinguishing component, and the data type is compared with the data type which can be processed by the application server. And data which belong to self processing can be reserved and sent to the data processing module, and data which do not belong to self processing can be directly discarded. The present invention exemplifies this manner by taking a real-time data processing application server as an example. After receiving the data such as the operation diagram data, the station diagram display, the station control command data, the train operation state, the emergency and the like, the real-time data processing application server judges the data type of the received data. The real-time data processing application server judges the data of the running state, the emergency, the station yard graph display and the station yard control command data of the train to be real-time data, and the running graph data is non-real-time data. The data type processed by the real-time data processing application server is a real-time data type, so that the running state of the train, emergency data, station map display and station control command data are reserved, and other types of data are discarded. And after receiving the data of the corresponding type, the real-time data processing application server processes the real-time data through the data processing module. Similarly, other types of servers, such as a running graph and scheduling command processing application server, and an integrated information processing application server, determine the type of received data, retain the type of data that can be processed by themselves, and discard other types of data.
In the present invention, the determination of the data type may include, but is not limited to, a determination based on a data frame flag, a data source or a data destination, and the like. For example, a data type field exists in the data frame, and after the relevant equipment receives the data, the data type is judged through the data type field; or judging the data type according to the source of the data; or the type of data is determined according to the destination to which the data is to be sent. The determination of the data type according to the present invention includes, but is not limited to, the above determination manner.
The present invention also provides a system for data transmission and reception in a dispatch centralized control system, which is characterized in that the system comprises:
a memory; and
one or more processors;
wherein the memory is communicatively coupled to the one or more processors and has stored therein instructions executable by the one or more processors to cause the one or more processors to perform the method of the embodiments.
The invention also provides a computer program product comprising computer executable instructions which are operable to perform the method described in the embodiments.
It should be noted that: the above examples are only for illustrating the technical solutions of the present invention, and are not limited thereto. The direct electrical connection between the devices in the system is not necessarily meant, and the description only indicates the logical relationship of signal transmission, for example, the "scheduling command" of the dispatching desk terminal is connected with the "application server a", the scheduling command module is not directly connected with the application server a, and the scheduling command is transmitted between the application server a and the dispatching desk terminal through a third-party device. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
