Time-bucket-based time series triggering method of metro integrated supervisory control system

Abstract

The invention discloses a time-bucket-based time series triggering method of a metro integrated supervisory control system. In the invention, based on the prior art of multi-specialty subsystems of the integrated supervisory control system and actual demands, functions in all specialties, which relate to time series control, are separated out, thus designing and realizing a new time-bucket-based timing trigger model for managing time series scheduling plans in all specialties in a unified way and meeting various control demands. The new time-bucket-based timing trigger model supports instant and convenient triggering management in all specialties through a real-time registration / de-registration mechanism. The significant advantages on the aspects of triggering control efficiency, control efficiency saving, development management maintenance and application requirement coverage are achieved.

Description

technical field [0001] The present invention is oriented to the requirement of arranging control plans according to time nodes and relying on computers to automatically trigger execution in subway / light rail comprehensive monitoring systems, and provides a unified timing trigger software model suitable for multi-specialty systems, and each professional application only needs to use the model By registering and notifying your own timing behavior, you can accept the trigger message of the model's automatic scheduling and execute the corresponding control actions, which greatly reduces the workload of routine operation and maintenance operations, and improves the accuracy of daily control of the system as well as the level of automation and intelligence . Background technique [0002] The subway / light rail integrated monitoring system (ISCS Integrated Supervisory Control System) adopts an integrated software and hardware platform and a dedicated communication network to collect...

Problems solved by technology

[0004] 1. At present, the processing time series control in the existing integrated monitoring system mainly relies on timers. Since the multiple time nodes in each time series plan are completely irregular, it is necessary to use at least one system timer for each plan and need to change according to the duration Frequent start and stop, considering that timers have low priority in operating system scheduling, there are defects in response reliability; at the same time, for hundreds of control needs of multiple specialties, a large number of timers are used and frequent triggers cause system resource overhead greatly increase

[0005] 2. The timing control of each specialty in the existing comprehensive monitoring system is designed and processed by each professional program separately, lacking a unified optimized management scheduling and solution, which is not conducive to system stability, code maintenance and program upgrades

[0006] 3. The existing comprehensive monitoring system is not flexible enough to control the time sequence of each major, and cannot freely control the coverage and cycle behavior of various time points according to the needs of each major, which is not conducive to the diversified implementation of subway operation management
