Automatic detection device for tipping bucket type rain sensor

Abstract

The invention relates to a device for calibrating a tipping-bucket rain gauge, in particular to a device for automatically calibrating the tipping-bucket rain gauge on line. The automatic detection device for the tipping bucket type rain sensor comprises a pipeline for communicating a water supply container with a detected rain gauge, a pump and a valve which are arranged in the pipeline, a power supply and power supply system, a power supply controller, a data detection sensor, a detection and calculation module, an operation and display module, interfaces among the modules, and a standard water storage container. According to the invention, a fixed container is arranged to supply water to the tested rain gauge, so that the device does not depend on the tipping frequency in the prior art, the total water injection rate can be objectively and actually measured, and the accurate verification of the rain gauge is realized by measuring the tipping frequency of the tipping bucket and the time of the corresponding measurement process.

Description

Technical field [0001] The present invention relates to an apparatus for tipping bucket rain gauge is calibrated, in particular a line automatic calibration apparatus for tipping bucket rain meter. Apparatus of the present invention comprises: a communication line between the water container and the test gauges, disposed in the line pumps and valves, and the power supply system, power controller, sensor data detection, calculation and detection module, operating and display module, and the interface between modules. Background technique [0002] The gauge is commonly used as a meteorological measuring instruments, using multi-stage tipping bucket rain gauge, the gauge is provided in such a tipping bucket rain sensor, which brings together rain water through the bearing, a filtered flows through the dump, the dump when after injection of a certain amount of rain, flip dump gravity, pour the water in the empty bucket, while the other side of the dump began to take water. Dump are i...

AI Technical Summary

Problems solved by technology

When calibrating this device, the total amount of water injected can only be obtained by measuring the number of tipping buckets. Due to the working error of the peristaltic pump and the deviation of the water volume of the tipping bucket under certain circumstances, the device cannot be verified. Accurate determination of the total water injected into the rain gauge and the number of tipping times required by the regulations

In addition, when simulating different rainfall, the flow velocity of the injection tipping bucket will also affect the movement of the tipping bucket, resulting in abnormal measurement errors
