In certain old residential communities within the city, secondary water supply pump rooms face a range of persistent issues—aging equipment, inadequate security systems, fluctuating water pressure, high pipe network leakage rates, inefficient manual inspections, and slow emergency responses. These problems frequently lead to inconvenient water supply for residents and an increase in complaints. To improve water supply quality and operational efficiency, the municipal water management authority has coordinated with water supply companies to digitally upgrade these aging pump rooms and enable remote, intelligent centralized management.

To address these challenges, WideIOT deploys industrial smart gateways that connect to the PLC controllers and various sensors within the secondary water supply pump rooms. These gateways collect real-time data including operating voltage, current, pump frequency, inlet and outlet water pressure, liquid level, and water quality parameters (residual chlorine, turbidity, pH value). The data is then transmitted via 4G/5G networks to a centralized secondary water supply monitoring and management platform. This enables remote monitoring, fault alarms, remote control, maintenance management, and data statistical analysis, providing the digital foundation needed to establish unattended pump room operations.

Key Features

1. Protocol Conversion and Secure Transmission

The communication protocols used by the water supply equipment PLCs vary widely across brands such as Siemens, Mitsubishi, Omron, Schneider, Delta, and Inovance. The gateway can convert these into standard protocols including SL651, SL427, SZY206, MQTT, and Modbus for reporting to the water management authority's platform. It also incorporates encrypted transmission and a secure firewall to ensure data safety and reliability.

2. Data Continuity with Store-and-Forward and Auto-Reconnection

With built-in store-and-forward and auto-reconnection capabilities, the gateway can temporarily store collected data locally during network interruptions. Once connectivity is restored, all stored data is automatically retransmitted, ensuring complete and accurate data records.

3. Real-Time Monitoring and Intelligent Alerts

The system continuously monitors key operational metrics including voltage, current, pump start/stop status, inlet/outlet pressure, liquid level, and water quality. When anomalies are detected—such as sudden pressure drops, water quality exceedances, or leaks—automatic alerts are triggered and sent to management personnel via WeChat, SMS, or email.

4. Remote Control and Unattended Operation

The gateway supports downlink control commands, allowing managers to remotely start or stop equipment, adjust pump frequency, or switch to backup pumps. This significantly improves emergency response times and operational efficiency, moving toward a model of minimal on-site inspection and fully unattended pump room operation.

5. Data Sharing and Statistical Analysis

The gateway supports data transmission to multiple centers simultaneously, feeding collected data to platforms used by the water authority, water supply companies, and property management services. This enables the generation of equipment operation reports, energy consumption analyses, and fault statistics, assisting management and enterprises in continuously optimizing dispatch strategies and maintenance schedules—ultimately extending equipment lifespan and reducing resident complaints.
