At present, not only rainfall monitoring data in agriculture plays an important role in it, but also occupies an important position in other fields. Rainfall monitoring data is an important basis for flood prevention decisions. The authenticity of this data is the basic prerequisite for achieving measures and determining scientificity and timeliness. Our country is a country with unbalanced rainfall. Because of various factors, our problems in rainfall work and the backwardness are obvious. To overcome the limitations caused by traditional manual data collection, we have developed and developed rainfall. The automatic measurement of rainfall by the monitor is an important system for the development of trends and tasks.
The PC is a universal device that is used in the intermediate station and the digital predecessor. It is connected through the RS-232-C serial port. Under the support of the rainfall monitor system software, complete the sending and receiving channel settings, automatic receiving, uploading, dialing callback, reading reports, generate various reports and other operations. The basic purpose of the rain intelligence communication is to realize the rapid transmission of rain information from various grassroots stations to flood prevention computer centers at all levels. In order to achieve this goal, it is required to design and build a star-shaped newspaper communication network that uses the city's rainy information intermediate station as a collection point, and on this basis, form a rainy weather information collection system for each station in the radiation flood control area.
Rainfall Monitor VB-based remote rainfall automatic monitoring and processing system has a simple structure, low cost, stable performance, accurate monitoring data and good real-time performance. When used, the device can measure rainfall automatically, in real-time, in an unattended manner, and transmit it to the intermediate station through the digital transmission and telephone network, and then to the upper level through the WAN. The trial operation of this system in some counties and cities of Shandong Province proves that a data transmission instrument measuring point can send data to the intermediate station within 5~10 seconds, which greatly shortens the transmission time compared with the traditional reporting method, and the accuracy of the information is reported. There has also been great improvement. The use of such a system is of great significance to the scientific and proactive nature of the flood control and drought decision-making and to the improvement of the working environment of the hydrological workers.
However, in many developed countries, the amount of development in this area is relatively rapid. For the basic rainwater information, satellite remote sensing technology is adopted. The level of modernization for the data transmission of communications adopts this method is high, and at the same time, flood prevention and Excessive rain and water work is a great help. Due to the high cost of this technology, it does not meet the basic conditions of my decisiveness. Therefore, the establishment of the above-mentioned automatic rainfall monitoring and processing system is a processing technology that is economic and practical in China.
