Problems solved by technology

[0006] The Chinese invention patent application with the application number 201010147427.6 and the name of a numerically controlled rain gauge discloses a rain gauge, which includes a water receiver, a test cylinder, a sensor arranged in the test cylinder, a test rod, a traction rope, a pulley, Stepper motor and central processor, although the rain gauge has improved a lot in range, but the structure is complicated, the mechanical transmission is too much, and there are deficiencies of easy wear of parts, high repair rate, high maintenance cost and low measurement accuracy
[0007] At present, various types of raindrop spectrometers are expensive, and the data need to be directly transmitted to an independent computer for processing and storage, so it is not suitable for temporary multi-point arrangement measurement, and is not suitable for providing high-resolution rainfall / water information in time and space

Embodiment 1

[0044] Such as Figure 1 to Figure 4 As shown, the rain gauge of this embodiment includes a collection and measurement unit 1, a drainage pump 2, a power supply unit 3, a drainage pipe 4, a dehumidification fan 5, a box body 6, an input device 7, a display 8, a controller 9, GSM and GPS antennas 10. Sensor switch 11. Among them, the collection and metering unit 1 is composed of a rain collector 1-1, a water inlet pipe 1-2, a normally open solenoid valve 1-3, a precipitation collector 1-4, a normally closed solenoid valve 1-5, and a pumping pipe 1-6. . The rain gauge of the present embodiment is provided with two sets of collection and measurement units 1, and the capacity of the precipitation collectors 1-4 in each collection and measurement unit 1 is different from each other, being one large and one small. In addition, each set of collection and measurement The components in the unit are basically the same in structure, and in the description of the following embodiments, ...

Embodiment 2

[0066] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that: from the top view, the water inlet connecting pipe 1-2 is inscribed with the precipitation collector 1-4, that is, the bottom surface circle of the water inlet connecting pipe 1-2 is inscribed with the precipitation collecting device. The top circle of the device 1-4 is inscribed, so that the outlet of the water inlet connecting pipe 1-2 is attached to the inner wall of the precipitation collector 1-4, so that the water flow discharged from the water inlet connecting pipe 1-2 can be attached to the precipitation collector 1 The inner wall of -4 flows down, which can reduce the splash of water and avoid measurement errors.

Embodiment 3

[0068] Such as Figure 6 Shown is a schematic structural diagram of the precipitation collector 1-4 according to Embodiment 2 of the present invention. The difference between this embodiment and Embodiment 1 is that two columns of metering pins 1-9 parallel to each other and vertically arranged are arranged on the metering circuit board 1-7, and the metering pins 1-9 are arranged at equal intervals. The reason for setting the double-column metering pins 1-9 on the metering circuit board 1-7 is: when the rain gauge is placed on an uneven plane, the liquid surface in the precipitation collector 1-4 is not parallel to the horizontal plane, but the liquid surface is inclined When measuring pins 1-9, it is easy to appear that the liquid level actually touched by the metering pins is not the real liquid level, so that there will be deviations. When setting double-column metering pins, the average number of two-column metering pins can be taken when measuring, which can avoid Deviat...

Abstract

The invention discloses a rainfall information acquiring and metering method and unit, and a rainfall meter. The rainfall meter comprises a box body, an acquiring and metering unit, a drainage pump, a drainage pipe, an input device, a display and a controller, wherein the acquiring and metering unit comprises a rainfall collector, a water inlet connection pipe, a rainfall collector and a water pumping connection pipe; a metering circuit board is arranged on the outer wall of the rainfall collector, a shift register is arranged on the metering circuit board, metering pins of the shift registerare arranged on the metering circuit board at equal intervals and extend into the rainfall collector, and signaling pins of the shift register extend into the rainfall collector and are positioned onthe bottom surface of the rainfall collector. According to the method disclosed by the invention, the signaling pins output modulation pulse electric signals, and rainfall (water) quantity and rainfall (water) rate are metered by adopting a liquid level measuring method and utilizing the characteristic of a conductive liquid through detecting electric signals received by the metering pins.

Description

technical field [0001] The invention belongs to the technical field of rain gauges or sediment meters, and in particular relates to a precipitation rate meter or a portable electromagnetic wave propagation environment characteristic parameter acquisition instrument, and a liquid level measurement method using a conductive liquid for time-space high-resolution precipitation and precipitation rate information Acquisition and measurement of precipitation acquisition measurement unit and rain gauge.
