A downstream river section in a certain city’s high-tech zone serves both as a flood discharge channel and an ecological water supplement source for three industrial parks and two towns. The local Environmental Protection Bureau has set up multiple automatic water quality monitoring stations in this area, with the client’s team responsible for third-party equipment inspections.

However, in actual operation, it was found that due to the remote and scattered locations of the monitoring stations, maintenance personnel can only inspect them twice a week. As a result, when a water pollution incident occurs, it often goes unnoticed until downstream fish deaths are observed or complaints are received from local residents. Furthermore, the lack of real-time data makes it difficult to identify upstream illegal discharges. Moreover, the data from different monitoring points is isolated, creating significant challenges for environmental law enforcement and ecological analysis.

To address this, WideIOT provides a highly reliable and efficient IoT solution. First, at each monitoring station located along river sections, discharge outlets, and regulation reservoirs, water quality analyzers are connected via RS485/RS232 to industrial IoT gateways. These gateways collect parameters such as ammonia nitrogen, total phosphorus, and COD in real time, standardize and process the data, convert it to the HJ212 protocol, and transmit it over 4G networks to both the enterprise inspection management platform and the environmental authority’s platform. This enables online inspection, alarms, and smart maintenance, significantly improving work efficiency and management.

Core Functions

1. Unattended Operation and Automatic Alerts

The system collects water quality parameters 24/7. Once the dissolved oxygen or heavy metal concentration exceeds a set threshold, the system automatically sends alerts via WeChat, SMS, or other messaging services, ensuring timely notification of abnormal conditions.

2. Online Inspection and Smart Maintenance

Users can view the operational status, work data, and inspection records of equipment at each monitoring station online. This allows for efficient maintenance scheduling. In the event of abnormal water quality, downstream gates can be remotely closed or emergency pumps activated.

3. Visual Data Dashboard

The system supports data transmission to multiple centers. All distributed monitoring points are aggregated on various platforms, which can automatically generate historical trend charts and reports. Data comparison makes it easy to trace pollution sources, providing an objective and accurate technical basis for cross-regional ecological compensation calculations.
