A substation in an industrial park supplies power to several precision manufacturing companies. The operation and maintenance team has long relied on traditional manual inspections using handheld infrared thermometers, which are labor-intensive, inefficient, and slow to respond. Therefore, the park needs a wireless temperature monitoring system that can operate 7×24 hours, provide automatic alerts, and require no human intervention—shifting the maintenance model from "reactive emergency repair" to "proactive early warning."

Temperature sensors are deployed at multiple points on-site, wired to a central connection point, and connected to a WideIOT industrial IoT gateway. The gateway transmits real-time temperature data to the park’s management platform via 4G networks. This enables real-time monitoring, alarming, management, control, and data analysis for various scenarios and power distribution cabinets, providing comprehensive and reliable data support for power safety management. As a result, the solution improves work efficiency and management capabilities.

Key Functions

1. 24*7 Real-Time Monitoring and Visual Display

The system continuously monitors enclosed or hard-to-reach points such as switchgear contacts and cable joints. Maintenance personnel can remotely view real-time temperatures and historical trend curves for each monitoring point via PC or mobile device, eliminating blind spots and hard-to-reach areas in manual inspections.

2. Multi-Level Intelligent Alerts and Proactive Warnings

When the temperature at any monitoring point exceeds a preset threshold or rises abnormally and rapidly, the system automatically sends alerts to responsible personnel via pop-ups, voice, SMS, WeChat, and other methods. This shifts the approach from "post‑failure repair" to "pre‑failure warning."

3. Data Storage and Trend Analysis

The gateway transmits all historical temperature data to a MySQL or SQL database, enabling the generation of temperature curves and operational reports. Maintenance personnel can analyze equipment aging trends, predict potential faults, and develop scientific preventative maintenance plans.

4. Unattended Operation and Mobile Inspections

As part of substation intelligence upgrades, on-duty personnel no longer need to frequently enter high‑voltage areas for temperature checks. They can monitor the temperature status of all equipment across the site from the control center or via a mobile phone, significantly reducing labor costs and safety risks, and supporting a new maintenance model of "unattended operation and centralized monitoring."
