Case Details
1. Overview
1.1. Project Overview
The Senwei Electronic "Safe Electricity Use" Management Cloud Platform utilizes IoT technology to conduct continuous data monitoring and statistical analysis on key factors associated with electrical fires—such as cable temperature, current, voltage, residual leakage current, and energy consumption. It detects safety hazards in electrical circuits and equipment in real-time (e.g., abnormal cable temperatures, short circuits, overloads, over-voltage, under-voltage, and leakage), thereby effectively preventing electrical fires.
Adhering to the principles of "market-led, government-guided, entity-driven, and socially participatory" operations, the project accelerates the deployment of "safe electricity use" systems. By leveraging technologies such as IoT, big data, and artificial intelligence alongside expertise in electrical safety, the platform employs data mining and analysis to detect hazards early, classify them, and understand their patterns of occurrence and progression. This enables the prediction of hazard trends and the integration of risk factors with socialized service systems. Ultimately, this establishes a safety prevention framework involving four key parties—predictive warning, hazard remediation, socialized services, and government information gathering. This approach enhances the precision of hazard prediction and safety service delivery, strengthens early warning and prevention capabilities regarding electrical fires, significantly reduces the incidence of electrical fires at the Jiangqiao Wholesale Market, and ensures the safety of people's lives and property.
The online service for electrical fire hazard management utilizes big data analytics, IoT technology, and cloud computing to identify, warn against, and manage electrical fire hazards. Through internet technology, it integrates offline service providers to offer comprehensive on-site hazard remediation services to relevant entities, ultimately achieving a significant reduction in the probability of electrical fires in the target area.

2. System Architecture
2.1. System Structure
The cloud platform for safe electricity management is designed with a layered, distributed architecture comprising the field device layer, the network communication layer, and the station control management layer. The detailed topology is as follows:
On-site units communicate with the electrical safety monitoring service platform via GPRS mobile networks (China Mobile or China Unicom 2G networks). The cloud platform can be hosted on a self-deployed server—requiring broadband access with a static IP address—or on a leased Alibaba Cloud server (which does not require a static IP at the local site).
On-site installed equipment collects data on residual leakage current, cable temperature, and electrical parameters (current, voltage, power, and energy consumption) for power circuits. This data is transmitted wirelessly to the safety monitoring service platform. When leakage current or temperature exceeds standard or preset limits, or when power usage exceeds thresholds, the platform or a mobile app issues an alarm signal. Simultaneously, an SMS notification is sent to the designated safety officer, and maintenance personnel are dispatched to address the on-site hazard.
2.2. Electrical Fire Hazard Remediation Model
Leveraging an online "Hazard Early Warning Platform" to collect operational data from electrical circuits, the system uses big data analytics to identify types of electrical hazards. An offline service team provides comprehensive remediation services to ultimately eliminate these hazards. The "Hazard Management Platform" provides regulatory bodies with tools for hazard monitoring, remediation management, and information analysis reports, enabling risk assessment of electrical fire hazards within the region.
System applications include an electrical fire monitoring and early warning system based on real-time monitoring, a hazard analysis and regulatory system based on monitoring data, and the establishment of an offline service framework driven by monitoring data.
Through stages such as project design, installation, management, commissioning, and operation, the system achieves real-time monitoring of electrical circuits in buildings, enabling functions like data collection, transmission, monitoring, and alarming. Real-time monitoring devices—including smart electrical safety sensor terminals, residual current transformers, current transformers, and temperature sensors—are installed in target power distribution cabinets. Multiple parameters (such as residual current, load current, and cable temperature) are collected and transmitted wirelessly to the platform server.
The system features remote real-time monitoring, alarms for abnormal data, historical data query and statistics, real-time display of dynamic data changes, and analysis of electrical circuit safety hazards and their remediation. Additionally, it supports mobile app access, third-party remote service hosting, remote firmware upgrades, and remote equipment maintenance.
