The wireless transmission of the descriptive flash flood early warning rainfall monitoring station is used for automatic rainfall monitoring in the wild environment. It has the functions of intelligent collection of rainfall data, long-term solid-state storage and remote transmission. It is widely used in the construction of high-density hydrological and flood control information stations in harsh outdoor environments. It is suitable for fields such as flash flood disaster early warning, field environmental hydrological monitoring, watershed flood control information stations, etc. This integrated rainfall monitoring station uses a combination of automatic monitoring and modern communication technology to realize an information system for synchronous collection, reporting and processing of rainfall at monitoring points. It has a small amount of data transmitted, a communication network with a wide geographical distribution and a comparative communication service. Bad characteristics. The system uses R wireless transmission to realize the data transmission scheme between the telemetry station and the command platform, and the system has high reliability and scalability functions.
The main design features are as follows:
The digital transmitter and the rain gauge are integrated, which is easy to install and reduces lightning and other interference introduced by the leads.
It has R online detection function. Once the R of the digital transmitter is detected to be stable online, the data will be transmitted, which improves the smooth rate of R data communication. The R data smooth rate can reach %. At the same time, this function also reduces the running time. time and reduce power consumption. Through this function, you can also know whether the number is sent successfully. If R is sent three times, if it is unsuccessful, send it once by SMS to ensure that the data is not lost.
It can be set remotely through a computer at the central station, and the data can be remotely transmitted to the user's mobile phone. The contents of remote settings include: station number, time interval, rainfall threshold, etc. Remote time adjustment can also be performed, and data can also be downloaded remotely.
It has solid-state storage function and can store megabytes of data. The rain gauge records a group of data for each tipping bucket, and the rain gauge station can store data for more than a year.
The digital transmitter uses an external power supply combined with rechargeable batteries and solar panels to ensure long-term stable operation of the equipment.
Equipped with a clock circuit: it can automatically adjust the time remotely. The data will be time-marked and the number will be sent when it rains. If there is no rainfall, the station will have up to one safety alarm every day.
