[0024] The specific structure of the utility model for realizing the above-mentioned online monitoring of ecological flow monitoring data of small hydropower stations in mountainous areas is as follows: the telemetry terminal supports RS485 interface externally, which can be adapted to access various types of commonly used sensors.

This flexibility enables the telemetry system to adapt to different monitoring needs and provide more comprehensive monitoring services; secondly, the RS485 interface is a commonly used communication interface standard, and various types of sensors can use the RS485 interface for communication. The RS485 interface of the telemetry terminal has strong compatibility and can be adapted to access various types of common sensors, such as temperature sensors, humidity sensors, pressure sensors, etc., so that the telemetry system can cover various monitoring indicators; connecting with the sensor through the RS485 interface can realize stable transmission of digital signals and reduce the possibility of signal interference and distortion. This can improve the accuracy and reliability of data acquisition and ensure the authenticity and effectiveness of monitoring data.

If the MEMS sensor data is within the threshold interval, it proves that the data is normal. If the sensor is not within the threshold interval, it proves that the data is abnormal, and the abnormal data is transmitted to the alarm unit. For example, the rainfall data is set as a normal threshold interval between X1-X3. If the real-time rainfall data is X2, it proves that the rainfall is normal. If the rainfall is X4, it proves that the rainfall is abnormal. By transmitting the abnormal data to the alarm unit for alarm, the staff is reminded to prepare emergency capabilities in advance.

For example, the monitoring data of different sites can be represented by layers, symbols, labels, etc. on the map, so that the monitoring indicators of each site can be more intuitively understood, the abnormal conditions of the data can be quickly judged, and the monitoring and management capabilities of the entire hydropower station can be strengthened; Operation and maintenance decision support: Through the comprehensive display and analysis of the data of each site, the monitoring IoT platform can provide support for operation and maintenance decision-making. For example, data display based on the GIS system can help operation and maintenance personnel quickly locate problems, accurately determine equipment abnormalities, and take corresponding maintenance measures in a timely manner.
