Description

SCADA system single-machine page rapid positioning method based on alarm content Technical Field The invention relates to the technical field of industrial automation, in particular to a SCADA system single-machine page rapid positioning method based on alarm content. Background In large industrial monitoring and data acquisition systems, such as photovoltaic power generation fields, petroleum pipeline transportation stations or smart grid dispatch centers, there are typically deployed tens of thousands of sensing points and equipment units. The devices continuously generate massive operation data, and the system needs to monitor key parameters such as current, temperature, pressure and the like in millisecond level in real time. When the data of a certain measuring point exceeds a safety threshold, the system triggers an alarm, and requires operation and maintenance personnel to quickly locate to a single machine monitoring page corresponding to the equipment so as to check detailed parameters, analyze fault reasons and execute control operation. However, because the equipment is large in scale and complex in topological relation, and the alarm is sudden and concurrent, operation and maintenance personnel need to manually search the target page in the multi-level menu, the scattered configuration diagram and the equipment list in the traditional method, the process is time-consuming and labor-consuming, the fault treatment opportunity can be delayed in an emergency condition, and even the linkage production accident is caused. At present, the core technical problem in such systems is that the single machine monitoring page of the associated equipment cannot be automatically, quickly and accurately positioned after the alarm is triggered. The existing SCADA system has alarm triggering and display functions, but a depth association mapping mechanism is absent between alarm information and a device monitoring page. Most systems only provide a static alarm list, operators need to manually search thousands of equipment lists for equipment corresponding to alarm points by virtue of self experience, and then search a monitoring page of the equipment through equipment names or codes in configuration software. The process is not only inefficient, taking tens of seconds or even minutes on average, but is also prone to positioning errors due to human factors. In addition, the prior art lacks an optimization mechanism for intelligent verification and multistage jump of alarm effectiveness, and cannot dynamically adjust a positioning strategy according to the real-time load, the network state and the data quality of the system, so that when high concurrency alarm or system resources are tense, page loading delay is obvious, and operation and maintenance response efficiency and system reliability are seriously restricted. Disclosure of Invention Aiming at the technical problems in the prior art, the invention provides a SCADA system single-machine page quick positioning method based on alarm content, which aims at solving the problems in the background art.
