Description
Technical Field
The invention relates to the field of automation control, in particular to an object-based comprehensive monitoring linkage logic configuration method.
Background
The rail transit integrated monitoring system realizes seamless connection with each subsystem through integration and interconnection, and can effectively utilize data acquisition and command issuing channels of the subsystems due to the fact that the integrated monitoring system completely integrates all data of related subsystems,
necessary inter-system linkage can be designed and realized according to linkage requirements among different systems so as to improve the safety of rail transit operation, improve the coordination among various professionals, improve the emergency handling capacity, reduce the working pressure of operators in emergency, avoid unnecessary operation errors and reduce the labor intensity.
According to the execution mode of various linkage functions and the matching degree of operators, the linkage functions can be divided into the following three types:
1) full-automatic linkage
The ISCS receives and processes the alarm/status trigger points of the interface system and then automatically sends the associated control commands to the interface system to be linked without human intervention. The operator is not allowed to cancel this linkage function at the HMI, only the system engineer has the right to cancel this function. Such as a linkage function of "automatically broadcasting train arrival information".
2) Semi-automatic linkage
When the alarm point related to the predefined linkage function triggers the action, alarm linkage information is sent out on the HMI to prompt an operator, and after the operator confirms the alarm linkage information, the ISCS automatically sends out a control instruction to a system needing linkage.
3) Manual linkage
Manual selection initiates a set of sequential control sequences involving multiple systems that automatically issue commands to different systems in order and lockout conditions.
Because the linkage function is oriented to the cooperative operation of a plurality of subsystems in the operation of the rail transit automation system when special working conditions occur, a set of mature linkage function needs to be capable of meeting the operation requirements, triggering conditions and execution requirements of various users.
The common method of linkage at present realizes linkage as an independent function module of a comprehensive monitoring system, and realizes linkage function in a conditional sequential control mode. The linkage configuration and execution process monitoring interface is integrated in the linkage module and then integrated into the picture of the comprehensive monitoring system through a plug-in technology installation interface.
Due to the linkage function requirements, the linkage service function requirements are not only included, but also the requirements of the user on the operation habits and interface impressions of the linkage mode are also included, and therefore the requirements of the linkage function may be greatly changed for different projects. Under the condition, the linkage is realized as an independent module, so that the module needs to be frequently modified, the development workload is increased, and the difficulty in maintaining the module in the future is increased.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The nature of the linkage operation in an automated control system is a sequence of actions that are conditionally executed. The method for comprehensively monitoring linkage logic configuration based on the object abstracts key nodes in linkage operation, designs a set of objects comprising logic operation, relation operation, action triggering, condition input and a timer in an object-based mode, and shows the logic relation between linkage actions through the association between the objects. And then, the orderly execution of the linkage action is realized by monitoring the change of the related attributes in the object.
The method provides a way to allow the user to flexibly configure the execution sequence of actions under various logic conditions. The user can configure and/or reverse operation, and can realize complex logic judgment and execution sequence of actions through the link between the configuration objects.
When triggered by the condition configured by the user, the program judges whether the logic condition is satisfied according to the configuration, triggers the action of the next node according to the judged result, and so on. Therefore, the linkage function under various demand scenes is realized.
In the method for configuring the object-based integrated monitoring linkage logic, the operation items in the linkage are abstracted into different function blocks, and each function block has an input and an output. The input to a function block instance may be data in the integrated monitoring system (as shown in FIG. 1), or the output of another function block instance (as shown in FIG. 2); the output of the function block instance can be a certain item of data in the integrated monitoring system or the output attribute of the function block instance itself, or both, according to the definition of the function block itself. The function block monitors input data, processes the data according to the predefined function of the function block when the change occurs, and outputs the result.
The N-to-N incidence relation is realized between the function block instances through input and output, so that various complex sequence relations can be flexibly configured.
