A medium-sized water conservancy project is responsible for several key tasks: supplying water to downstream towns and villages, supporting agricultural irrigation, flood control and storage, and ecological water replenishment. However, due to its age and increasingly rigid management systems, the facility faces typical "blind, deaf, and mute" challenges:

1. Key sites such as the dam, sluice gates, pumping stations, and hydrological monitoring stations are far apart. Data is still collected manually and reported on paper, causing long delays when accessing critical information and hindering decision-making.

2. The site uses a mix of PLCs from Siemens, Omron, ABB, domestic brands, and older serial devices with incompatible communication protocols and data formats. Each site operates in isolation, creating "data silos." When a failure occurs, nobody is alerted.

3. Critical equipment like gate actuators and pump motors lack real-time monitoring. Failures are only addressed after they happen, leading to long mean time to repair (MTTR) and disrupting downstream water supply and usage.

To address these issues, WideIOT has developed a smart water conservancy IoT system covering the full chain of "perception – transmission – analysis – control – decision-making," with industrial IoT gateways at its core. The gateway connects to sluice gate PLCs, pump PLCs, water level meters, flow meters, pressure sensors, and more. It collects real-time equipment status and process data, supports 4G + Ethernet dual-network backup, and sends the data to a smart water management platform. This enables remote monitoring, alerting, management, control, maintenance, and data analysis for water conservancy operations.

Key Features

1. Collects core data including gate opening status, operating status, upstream/downstream water levels, pumping station flow/head, and motor voltage/current – breaking down data silos. When an alert is triggered, notifications are sent via SMS, WeChat, email, etc., specifying the affected site, fault type, and abnormal values.

2. Provides a unified dashboard with map-based site locations and statuses, real-time gauges for key metrics (e.g., gate opening, pump station flow), and trend curves (e.g., flow changes, motor current fluctuations). Managers can monitor all sites remotely without being physically present.

3. Allows managers to send control commands through the platform, such as remotely opening/closing gates (e.g., adjusting gate opening for flood release or irrigation flow control), starting/stopping pumps, and adjusting operating parameters (e.g., pump motor speed, outlet pressure threshold). This improves response speed and management efficiency.

4. Creates equipment records including model, installation date, maintenance history, spare parts inventory, etc., with support for custom maintenance schedules. Maintenance staff can report repair progress and results via the platform, forming a closed-loop process of "alert – dispatch – repair – verification," preventing missed or duplicate maintenance and extending equipment life.

5. Automatically stores historical data, allowing queries by site and time period (day/week/month/year) for gate operation records, pump station parameters, fault handling details, etc. Generates multi-dimensional reports covering equipment efficiency (e.g., average daily pump runtime, failure downtime rate), providing data support for future upgrades and operational optimization.
