Abstract

The invention discloses a rainfall titration tester. The rainfall titration tester comprises a cabinet, a single-chip microcomputer is arranged in the cabinet, and the single-chip microcomputer is connected with a memory, a water injection metering unit, a display control unit and a power supply unit. The rainfall titration test method comprises following steps: apparatus calibration; and titration testing. By employing the above technical scheme, according to the tester and the test method, by employing the principle of constant-flow pumping by a charge pump, artificial errors and field calibration uncertainty caused and brought by difficult control of the water injection speed by artificial titration are eliminated, an error evaluation standard is normalized and unified, the acquisition accuracy of the rainfall is improved, more reliable decision bases can be provided for improvement of the prediction precision of flood early warning, and the blanks of field calibration and test tools for rainfall acquisition accuracy are filled in.

Description

technical field [0001] The invention relates to the fields of on-site error detection and calibration of rainfall automatic collection sensors, in particular to a rain titration tester and a rain titration test method. Background technique [0002] At present, automatic rainfall stations are widely used in hydrology, water conservancy and other industries to collect precipitation data. Rain gauge titration tests are usually performed manually using special measuring cups. Due to the difficulty in controlling the titration speed of water injection, operators have different understandings of titration methods and error assessment requirements, and there are problems such as human operation errors and non-standard error assessments in titration tests, resulting in inaccurate precipitation collection. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects, and provide a rain titration tester an...
