Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the ATS system consists of a duty control center, a backup control center, a depot (not shown in the figure) and a station. The ATS system includes a server and a client, and the server includes multiple servers in the duty control center or backup control center. , responsible for data collection, analysis and processing; the client includes the components used for data display and human-computer interaction in each part of the ATS system.

[0016] Such as figure 2 As shown, the server will continue to collect and process data after the system is started. If it detects a change in the data, it will package the changed data according to the pre-agreed communication protocol and broadcast it to the entire system through the message bus. All clients who have subscribed to the data will receive the data packet, judge the data type, ana...

Abstract

The invention discloses a data updating and synchronizing method for a human-computer interface in an automatic train supervision system. The data updating and synchronizing method comprises the following steps: (1) interactive data of all signal devices are analyzed, and a unified data type is formulated for the interactive data of all the signal devices; (2) a communication protocol which is sent from a server-side to a client-side is formulated; (3) the server-side detects changes in the data in the step (2) and then broadcasts the changed data to the whole system according to the formulated communication protocol, and the client-side which subscribes to a change message receives the change message and conducts de-encapsulation so as to update relevant information on the human-computer interface; (4) the client-side periodically sends requests to the server-side for all the data which are subscribed to by the client-side, and if the data are different, the data on the human-computer interface are updated. The data updating and synchronizing method for the human-computer interface in the automatic train supervision system achieves the effects of interaction, update and synchronization of large volume data of the client-side and the server-side in the ATS system, and guarantees the real-time performance of the data of the server-side.

Description

technical field [0001] The invention belongs to the field of urban rail transit, and mainly relates to a data update and synchronization method for a man-machine interface of an automatic train monitoring system. Background technique [0002] The rail transit automatic train operation control system (ATC) includes the automatic train protection system (ATP), the automatic train operation system (ATO) and the automatic train monitoring system (ATS). The three subsystems form a closed-loop system through an information exchange network to realize ground control and The combination of on-board control, local control and central control constitutes an automatic train control system based on safety equipment and integrating functions such as train command, operation adjustment and train driving automation. The main function of the ATS system is traffic command and train dispatching, which is the core of train operation. The subway operators monitor and control the running trains ...
