Strengthen the integration of hydrological technology, and prevent turbulent floods with instruments and meters

In recent years, although my country's hydrological science and technology has made great achievements, it has not been able to adapt to and meet the new requirements of the country's economic and social development and the development of water conservancy in the new era for hydrological work. Compared with the development, there is a big gap. The main problems in the development of hydrological science and technology are: relatively weak basic research, incomplete scientific and technological innovation and promotion and application system, relatively lack of hydrological science and technology talents, and obviously insufficient investment in hydrological science and technology. These major problems directly affect the development of hydrological science and technology. In order to eliminate water hazards and make full and rational use of water resources, my country has been monitoring river hydrology since the last century. However, with the development of science and technology and people's attention to water conservancy projects, the traditional manual monitoring method can no longer adapt to the development of society, and more scientific hydrological monitoring instruments are needed. Floods are turbulent, instrumentation aids hydrological monitoring The hydrological monitoring system is suitable for real-time monitoring of hydrological parameters such as rivers, rivers, lakes, reservoirs, channels and groundwater by the hydrological department. The monitoring contents include: water level, flow, flow rate, rainfall (snow), evaporation , sediment, ice, moisture content, water quality, etc. The hydrological monitoring system uses wireless communication to transmit monitoring data in real time, which can greatly improve the work efficiency of the hydrological department. Among the measuring devices used are rain sensors, water level gauges, industrial cameras or other instrument transmitters. Water level transmitter is a commonly used transmitter in water industry automation. It is widely used in water level measurement and control in industrial water treatment engineering, building water tower water level, environmental protection, water conservancy, power plants, urban water supply and drainage, hydrological exploration and other fields. Easy to install and easy to use. The working principle of the water level transmitter is that the pressure acts directly on the diaphragm of the sensor, causing the diaphragm to produce a micro displacement proportional to the pressure of the medium, so that the resistance of the sensor changes, and the electronic circuit detects this change and converts the output. A standard signal corresponding to this pressure. water level gauge“level gauge”or“Liquid level gauge”. Commonly used are glass level gauges, pressure level gauges, buoy level gauges, capacitance level gauges and resistance level gauges. Under high temperature and high pressure, isotope level gauges can also be used. A water level gauge is an instrument that can automatically measure and record the water level of water bodies such as rivers, lakes, and irrigation canals. In practical application, the choice of water level gauge is different according to the different project scale and form, different development needs, and different application locations. With the development of society, the progress of the times, the improvement of engineering quality, the improvement of signal acquisition accuracy, the enhancement of product practical performance, the less investment, the less land occupation, and the convenient construction of water level gauges, more and more water conservancy projects will be used. choose. Rainfall sensor is suitable for meteorological stations, hydrological stations, agriculture, forestry, national defense and other relevant departments to remotely measure the amount of liquid precipitation, the intensity of precipitation, and the start and end time of precipitation. Used for flood control, water supply scheduling, hydrological management of power stations and reservoirs for the purpose of hydrological automatic monitoring and reporting systems, automatic field monitoring and reporting stations, and precipitation measurement sensors. Common rain sensors mainly include flow type rain sensors, electrostatic rain sensors, piezoelectric rain sensors, and infrared raindrop sensors. Due to the close reliance on the scientific and technological and human resources advantages of universities and scientific research institutions, my country has strengthened the construction of hydrology and water resources laboratories, engineering research centers and hydrological experimental stations, accelerated the construction of hydrological scientific research systems, and organized scientific and technological research on major hydrological science and technology issues.“national team”, by establishing“Open, fluid, competitive, collaborative”and improve the overall level of my country's hydrological scientific and technological achievements.
