Abstract
The invention discloses a measurement method of rainfall, relates to the technical field of rainfall measurement, which solves the problem that the measurement is precious and convenient, the service life is improved; the measurement method comprises the following steps: placing an ultrasonic ranging sensor on the top of a water storage tank, placing a hopper on the top of the ultrasonic sensor which is used for receiving the rainfall and installing an inlet solenoid valve on the lower end of the hopper. A discharging solenoid valve is arranged on the lower part of the water storage tank. The change of the ranging in the unit time is converted to the rainfall by the microcomputer in the instrument. While the water level reaches a certain height, the inlet solenoid valve is closed by the microcomputer in the instrument; the discharging solenoid valve is opened by the microcomputer in the instrument to discharge the water. While the water is discharged completely, the inlet solenoid valve is opened and the discharging solenoid valve is closed, the addition of the water in the hopper and the discharged water is the rainfall in the current unit time. The measurement method of the rainfall provided by the invention can accurately and automatically measure; because a mechanical device is not installed, the service life is long, and the use is convenient.
Description
Technical field
The present invention relates to a kind of technology of rainfall measurement, particularly relate to a kind of measuring method of rainfall.
Background technology
Present known rainfall measuring method is mechanical type or hydrocone type, and these two kinds have the life-span short, measure inconvenient defective.
Summary of the invention
To the defective that exists in the above-mentioned prior art, technical matters to be solved by this invention is: can accurately measure easily, and can improve its life-span.
In order to solve the problems of the technologies described above, the present invention provides a kind of measuring method of rainfall, and step is following:
1. put a ultrasonic ranging sensor at the top of a water tank.
2. above ultrasonic sensor, put a funnel and be used to receive rainfall.
3. adorn an entering water electromagnetic valve in the lower end of funnel.
4. adorn the solenoid valve that discharges water in the bottom of water tank.
5. be connected distance measuring sensor with instrument.
6. the microcomputer computer in the instrument is converted into rainfall to the variation of finding range in the unit interval.
7. when water level reaches certain height, close entering water electromagnetic valve, open the solenoid valve that discharges water, bleed off water by the control of the microcomputer computer in the instrument.
8. when the microcomputer computer in the instrument was measured water and put through distance measuring sensor, the unlatching entering water electromagnetic valve was closed the solenoid valve that discharges water.
9. the microcomputer computer in the instrument, adding the water yield of having put is the rainfall in the current unit interval.
Utilize the measuring method of a kind of rainfall provided by the invention, can be accurately, robotization ground is measured, and do not have mechanical hook-up, thereby the life-span is long, and is easy to use.
Embodiment
Ultrasonic sensor adopts hermetic model, and the microcomputer computer in the instrument can adopt, MEGA16, and 8051 single-chip microcomputers such as grade are made.
Claims (1)
1. the measuring method of a rainfall is characterized in that, the step of method is following:
