(5) Meteorological sensors: monitoring temperature, humidity, wind speed, wind direction and rainfall, providing meteorological data base for predicting hydrological events.

In the hydrological monitoring system, how is the data transmitted to the cloud platform center in real time?

The process of real-time data transmission to the cloud platform center usually includes the following steps:

1. Sensor data collection: Sensors (such as water level, flow, water quality sensors) distributed in each monitoring point continuously collect data.

2. On-site data processing: The intelligent control box or data acquisition unit performs preliminary processing on the raw data, which may include filtering, calibration and other operations.

3. Data transmission:

   - Wired transmission: data are transmitted directly to the cloud platform via a wired network (e.g. Ethernet).

   - Wireless transmission: send data to the cloud platform via wireless communication technology (e.g. GPRS/3G/4G/5G, Wi-Fi, satellite communication).

4. Cloud Platform Receiving and Processing: After receiving the data, the cloud platform stores, analyzes, and generates visualization reports or triggers early warning mechanisms through algorithmic models.

5. Data display and analysis: The cloud platform displays the data to users through web pages or mobile applications, and provides data analysis tools for users to conduct in-depth analysis.

6. Safe transmission guarantee: Encryption technology is used during data transmission to ensure data security and privacy protection.

2. Equipment procurement and installation:

Procure the required sensors, data collectors, data transmission equipment, etc. according to the program design.

Installation and commissioning of the equipment at the selected monitoring sites to ensure that the equipment can work properly and collect data accurately.

The time for this phase depends on the cycle of equipment procurement, the complexity of installation and commissioning, and the number and distribution of monitoring stations.

3. Data platform construction and commissioning:

Build a platform for receiving, storing, processing and analyzing data, including database, data processing software, data analysis tools and so on.

Test and debug the data platform to ensure that it can accurately receive and process data from monitoring stations.

The time of this stage depends on the complexity of the data platform, the development cycle and the progress of debugging.
