JT-204ZBeidou Rainfall Monitoring Station

JT-204ZBeidou Rainfall Monitoring StationSuitable for meteorological stations, hydrological stations, agriculture and forestry departments, used to remotely measure liquid precipitation, precipitation intensity, and precipitation start and end times, used for Beidou satellite transmission in the region without electricity or signal, default BeidouSatellite 2, optional Beidou-3 satelliteThis instrument strictly follows theSL61-2003 Hydrological Automatic Measurement and Reporting System Specification, GB11831-89 Hydrological Measurement and Reporting Device Remote Sensing Rain Gauge、The national standard GB11832-89 for tipping bucket rain gauges requires the organization of production, assembly, and calibration. It can be used for hydrological automatic monitoring and reporting systems and automatic field monitoring and reporting stations for flood control, water supply scheduling, and water management of power stations and reservoirs. Technical parameters: Water bearing diameter: Φ 200 ± 0.6mm, outer blade angle 45 degrees Measurement range: ≤ 4mm/min (precipitation intensity) Resolution: 0.1mm Accuracy: ± 4% (indoor static test, rainfall intensity is 1mm/min) Output signal: switch contact on/off signal Working temperature: 0-50 ℃ Storage temperature: -10 ℃ -50 ℃ Product weight: Water bearing bucket weight 1700g, total weight 3300g Power supply mode: DC3.3V Output mode: pulse signal.The tipping bucket rainfall sensor consists of a rainfall microcomputer collector and transmission module. The automatic rainfall collector has functions such as real-time rainfall display, automatic recording, real-time time, historical data recording, over limit alarm, and data communication. The rainfall electrical signal obtained by the tipping bucket rain sensor is transmitted to the automatic collector, and the automatic collector will collect the rainfall value throughBeidou satelliteTransfer, transmit to the data center computer.

When measuring rainfall with a tipping bucket rain gauge, the range of the measuring tipping bucket changes. However, after we have debugged it, its range becomes fixed. During the counting process of the measuring tipping bucket, that is, if there is still rainwater in the funnel during the flipping process, some of the rainwater will be lost along with the flipping, and this part of the rainwater will be considered invalid and not included in the counting. This leads to a smaller final measurement result. Our experimental data can prove this point. So, to solve this problem, it is necessary to make the flipping angle or inclination angle of the measuring tipping bucket relatively small, or to ensure that there is no rainwater in the funnel during the flipping process of the measuring tipping bucket, that is, to ensure that the range of the four water storage buckets of the upper tipping bucket and the measuring tipping bucket is consistent. However, the inclination angle of the measuring tipping bucket is inevitable, so the latter can only be used to reduce errors, and this process needs to be solved during debugging. It is necessary to ensure that the rainwater passing through the upper tipping bucket only needs to flip the measuring tipping bucket exactly once. After this stage of debugging is completed, there will be no ineffective rainwater loss during the flipping process of the measuring tipping bucket.
