Abstract
A sensor for indicating rainfall is disclosed, in particular to detect the great rainfall. A magnetic floater whose density is smaller than water is mounted in the non-magnetic measuring tank, the magneto sensors are mounted on the outside of the tank according to the unit of measurement, the magnetic floater rises along with the accumulation of the rainfall, and triggers the magneto sensors to output electric signals. The rainfall is indicated according to the different location of the magneto sensors.
Description
Affiliated field
The present invention relates to a kind of sensor of indicating rainfall amount, especially to the detection of heavy rainfall.
Background technology
In China, the metering of rainfall amount, the rain sensor that generally uses also is based on the tipping bucket rain gauge that mechanical principle designs at present, the hydrocone type rain sensor that also develop a century 40, the fifties in the use in some place.
Because tipping bucket rain gauge also will add that this tipping bucket rain gauge is to come the accommodometer accuracy of measurement by regulating mechanical equilibrium by manually going observation at present.Intrinsic by mechanical realization, as can't to eliminate inertia and resistance, make that the degree of accuracy and the resolution of this tipping bucket rain gauge are low: for trickle rainfall it can not record, and it has little time upset for heavy rain, heavy rain, rainfall record error of omission or few note occur.And rainfall is big more, the time of continuous rainfall is long more, and record is just inaccurate more, and the measurement deviation that is produced is also just big more.
Summary of the invention
For overcome rain sensor for trickle rainfall it can not record, and it has little time upset for heavy rain, heavy rain, the deficiency of rainfall record error of omission or few note occurs.Rain sensor of the present invention not only can overcome above-mentioned shortcoming, can also measure rainfall more accurately.
The technical scheme that technical matters adopted that the present invention solves is: the magnetic float of a density less than water is installed in non-magnetic conduction batch box, outside bucket according to measurement unit, the magneto sensor of some is installed, when magnetic float rises along with the accumulation of rainfall, trigger corresponding magneto sensor output electric signal, circuit is indicated corresponding rainfall according to the electric signal of diverse location magneto sensor.
The present invention can also be widely used in the capacity of measuring various container solution except being used to detect the rainfall.
Embodiment
Non-magnetic conduction batch box adopts the plastic production of certain degree of hardness, and its liquid level area is with to adopt the rain area proportional, with correct indication rainfall.Magnetic float adopts high magnetic steel, is installed in the airtight plastic float body, and magneto sensor is arranged in the batch box outside according to measurement unit.
Claims (1)
1. rain sensor, the magnetic float of a density less than water is installed in non-magnetic conduction batch box, outside bucket according to measurement unit, the magneto sensor of some is installed, when magnetic float rises along with the accumulation of rainfall, trigger corresponding magneto sensor output electric signal, circuit is indicated corresponding rainfall according to the electric signal of diverse location magneto sensor.
