Omnibearing safety protection and fault early warning system for cooling tower Technical Field The invention relates to the technical field of industrial management, in particular to an omnibearing safety protection and fault early warning system of a cooling tower. Background In a large industrial production scenario, cooling towers are typically distributed over multiple production links, as one of the energy-intensive facilities, whose operational stability has an indirect but significant impact on the overall operational efficiency of the enterprise. Due to long operation time and high environmental exposure, the cooling tower body and the auxiliary structure have the problems of corrosion, aging, material fatigue and the like, and periodic monitoring and maintenance management are needed across departments. At present, an enterprise usually adopts local monitoring equipment (such as noise, vibration and water quality recorder) to collect cooling tower operation data, but the data are in a state of scattered storage and passive analysis at a system level, so that the data are difficult to be effectively integrated into an industrial data management platform of the enterprise, and task decision and response coordination of cross departments cannot be efficiently supported. In addition, in the actual management process, the task of disposing the hidden trouble of corrosion of the cooling tower often involves a plurality of responsibility bodies such as operation, equipment, water treatment, exterior Bao Weibao and the like. Due to the lack of a complete responsibility identification-conflict judgment-task allocation mechanism, management bottlenecks are very easy to generate, responsibility crossover is unknown, the same hidden danger area is repeatedly responded or mutually pushed by a plurality of departments to cause task conflict or handle vacuum, a scheduling mechanism is rigidified, dynamic optimization paths based on risk grades, resource availability and task association degree are lack, resource mismatch and response delay are easy to cause, data utilization efficiency is low, acoustic, water quality and other data are only used for equipment state judgment, task triggering and responsibility decision basis of an organization level cannot be raised, and intelligent closed loop of the whole flow is difficult to realize. Although some industrial systems have deployed operation and maintenance platforms or maintenance work order systems, most of the industrial systems still stay in static order assignment and manual auditing stages, and task conflict analysis, priority calculation and resource collaborative allocation facing to 'corrosion risk+multi-responsibility nodes' are not realized yet.

Therefore, an omnibearing safety protection and fault early warning system for the cooling tower is provided. Disclosure of Invention The invention aims to provide an omnibearing safety protection and fault early warning system for a cooling tower, which is used for realizing dynamic hierarchical management of corrosion information, collision recognition of responsible nodes and self-adaptive scheduling of response tasks, so as to promote industrial data management to be changed from 'perceived island' to 'closed loop control'. The system comprises an acoustic-chemical data acquisition module for acquiring an acoustic-chemical data set, a corrosion risk identification module for establishing an acoustic-chemical coupling model, performing corrosion risk assessment on a target area and outputting space positioning information, a responsibility node matching module for automatically matching responsibility nodes and constructing an initial association relation of the corrosion point and the responsibility node, a cross responsibility identification and optimal response path generation module for calculating responsibility coverage conflict degree of each responsibility node by using a responsibility coverage conflict measurement model and judging whether cross nodes exist or not, a comprehensive scheduling scoring model constructed if the cross nodes exist, generating an optimal response path based on task response time delay, load balance indexes and node priority weights, and a task scheduling module for distributing maintenance tasks to the corresponding responsibility nodes according to the optimal response path in a priority order for hierarchical collaborative response management.
