Embodiment Construction
[0026] The present invention will be further described below in conjunction with accompanying drawing:
[0027] like figure 1 As shown, a safety command control method for an automatic train monitoring system, the equipment includes an ATS workstation and a command receiving device, and the ATS workstation 1 and the command receiving device 2 jointly control the input and issuance of safety commands. ATS workstation 1 is provided with four threads inside when it sends a security command to the command receiving device, including a main program thread 11, a command thread 12, a secondary command thread 14 and a monitoring thread 13, wherein the main program thread 11 starts other threads; The command thread 12 and the secondary command thread 14 are respectively responsible for the operation interface, logic processing, communication processing and security processing of the two command phases, and the generated commands are all sent to the receiving device; the monitoring thre...

The invention relates to a safety command control method for a train automatic monitoring system. The safety command control method comprises the following steps that a first command is sent to a command receiving device by an ATS workstation; the first command is received and fed back by the command receiving device; feedback information is received and judgment is produced by the ATS workstation, and when the feedback information is consistent with the sent command information, a second command is sent to the command receiving device by the ATS workstation; the second command is received andjudged by the command receiving device, and when the second command is consistent with the received first command, the commands are confirmed to be received and feedback of the received secondary command information is performed; and when the secondary command feedback information received by the ATS workstation is consistent with the secondary command issued by the ATS workstation, the commandsare confirmed to be successfully sent. According to the safety command control method for the train automatic monitoring system, the input and the transmission of security commands to a target devicecan be safely and reliably controlled on a single workstation, the operational complexity is reduced, and the investment for the posts is reduced.
Description
technical field [0001] The invention relates to the technical field of railway signal communication, in particular to a safety command control method for an automatic train monitoring system. Background technique [0002] In the field of rail transit, the automatic train monitoring system (ATS) is used to realize the functions of train operation monitoring, train command and control, and dispatch management, which directly affects the operation safety and efficiency of rail transit. The work of the ATS system needs to communicate with other subsystems of the ATC (Automatic Train Control) system (computer interlocking system CBI, zone controller ZC, automatic train protection system ATP, automatic train operation system ATO). The system collects various information on rail transit operation and sends scheduling and control commands to each subsystem to command the operation of each system to jointly ensure the safety and efficiency of train operation. [0003] In the interac...
