Remote Rainfall Stations (JD Series)
1. Basic description
The JD series tipping bucket automatic rainfall station is an all-weather meteorological monitoring equipment designed specifically for observing ground rainfall and air temperature in areas prone to geological disasters such as flash floods. It is one of the important non engineering measures to prevent debris flow disasters to effectively monitor rainstorm and continuous precipitation, and to carry out forecast and prediction. In order to effectively carry out precipitation monitoring, a system solution has been developed specifically for the management of small and medium-sized rivers and the reinforcement of small and medium-sized reservoirs, in order to provide system solutions with new concepts, designs, and high-performance, high stability, and high reliability technical requirements, and to develop and produce cost-effective products.

4. System composition:
The JD series tipping bucket automatic rainfall station consists of tipping bucket rainfall sensors, 4G full network telemetry terminal RTU, and DC power supply system. The telemetry terminal RTU has functions such as rainfall display, automatic recording, real-time clock, historical data recording, over limit alarm, and data communication. The rainfall pulse signal obtained by the tipping bucket rain sensor is transmitted to the telemetry terminal RTU, which then transmits it to the data center computer via 2G or 4G network.
