In the fields of industrial production, property management, security monitoring, etc., the standardized and intelligent management of equipment inspection and safety inspection directly affects operational efficiency and risk prevention and control capabilities. The patrol and inspection management system, as a core application software running on a PC, integrates IoT, big data analysis, and visualization technologies to build a full process digital control system of "planning execution analysis optimization". This article analyzes how it reshapes the traditional inspection mode from three aspects: functional architecture, application value, and technological advantages.

　　1、 Full scenario functional architecture: covering the entire lifecycle of inspection

1. Intelligent planning arrangement: The system supports generating inspection tasks from multiple dimensions such as time (day/week/month), region, and equipment type, and can customize inspection points, routes, and standard operating procedures (SOP). For example, in the management of chemical industrial parks, differentiated inspection frequencies can be set for high-risk areas such as tank areas and pipeline corridors to ensure 100% coverage of key equipment.

2. Multi terminal data collaboration: Real time synchronization between PC and mobile inspection terminals (PDA/mobile), inspection personnel automatically upload device status, environmental parameters, hidden danger photos and other data collected through mobile terminals to the PC backend, forming a structured database. A property group application shows that the data return efficiency has increased by 70%, and the missed detection rate has decreased to below 0.3%.

3. Visual Analysis Dashboard: The system has a built-in BI analysis module that can generate over 20 visual reports, including trend charts of equipment health, heat maps of inspection time distribution, pie charts of hazard types, and more. The management can grasp the global operation and maintenance status in real time through the PC end, such as predicting motor bearing faults 30 days in advance through vibration spectrum analysis.

4. Closed loop rectification tracking: After discovering hidden dangers, the system automatically triggers the work order process, assigns a responsible person, and sets a rectification deadline. The rectification results need to upload comparative photos and testing data, forming a complete closed loop of "discovery dispatch processing acceptance". After being applied in a certain steel enterprise, the rectification cycle for hidden dangers has been shortened from 72 hours to 12 hours.

　　2、 Core application value: cost reduction, efficiency improvement, and controllable risk

1. Optimization of labor costs: By using intelligent scheduling algorithms to reduce redundant inspection frequency by 30%, a certain power plant has saved over 2 million yuan in labor costs annually.

2. Equipment lifespan extension: Predictive maintenance based on parameters such as vibration and temperature reduces unplanned downtime by 45%.

3. Compliance assurance: Automatically generate inspection reports that comply with standards such as ISO55000 and GB/T 31969, making it easy to handle audit checks.

4. Speed up emergency response: In case of sudden accidents, the PC can quickly access the surrounding inspection records and equipment files, providing data support for command and decision-making.

　　3、 Technical architecture advantage: the balance between stability and scalability

The system adopts B/S architecture and is based on Developed with NET Core and Vue 3, compatible with both Windows and Linux platforms, supporting point data storage. Through microservice design, functional modules can be decoupled and flexibly integrated with heterogeneous systems such as access control systems, ERP, MES, etc. A smart park project synchronizes 20+subsystem data through API interfaces to build a unified equipment operation and maintenance center.

Practical case: After deploying the system, a subway operating company achieved digital inspection of 18 stations and over 3000 devices. The generation time of inspection reports was shortened from 4 hours per station to 10 minutes per station, and the equipment failure rate decreased by 28% year-on-year. From a single inspection tool to an enterprise asset health management platform, the PC based patrol inspection management system is becoming the infrastructure for digital operation and maintenance in the Industry 4.0 era.
