Embodiment
Structure of the present utility model is as shown in Figure 1-2: a kind of intelligent alarm rain gage, comprise rain gage and alarm, and comprise a graduated cylinder 3, graduated cylinder 3 bottoms are provided with water drain valve 5, graduated cylinder 3 bottoms are provided with pressure transducer 6, and pressure transducer 6 is connected with alarm, and pressure transducer 6 is arranged on holder 7.Graduated cylinder 3 of the present utility model is transparence cylindrical shell, and the barrel of graduated cylinder 3 is provided with metering ruler 4.The casing of alarm adopts polyphenylene oxide to make.
The utility model in use, also can install additional and hold rain mouth 2, holds rain mouth 2 and is arranged on support 1 and with graduated cylinder 3 and is communicated with.
Pressure transducer 6 of the present utility model is piezoresistive pressure sensor, comprise the silicon pressure drag chip of being made by the resistor stripe being integrated on monocrystalline silicon diaphragm, extraction electrode lead-in wire, the one side of silicon pressure drag chip is and the high pressure chest of tested pressure communication that another side is the low-pressure cavity being communicated with atmosphere.
Silicon pressure drag chip is circular, and diameter and Thickness Ratio are 20~60, in silicon pressure drag chip (N-type) localization, spreads 4 P impurity resistance bars and is connected into full-bridge, and wherein two are positioned at compressive stress district, another two in tension district, with respect to diaphragm Central Symmetry.
Described pressure transducer 6 is connected with alarm by cable, and alarm comprises casing, is arranged on the LED display on casing and is arranged on the control circuit in casing.
Principle of work of the present utility model is as follows: rainwater enters graduated cylinder 3 by holding rain mouth 2, also can not install additional to hold rain mouth 2 and make rainwater directly enter graduated cylinder 3, from the metering ruler 4 of graduated cylinder 3, can directly read amount of rainfall; After rainwater accumulates in graduated cylinder 3, the pressure that the weight of rainwater produces passes to pressure transducer 6, and pressure transducer 6 is a piezoresistive pressure sensor, adopts integrated technique that resistor stripe is integrated on monocrystalline silicon diaphragm, makes silicon pressure drag chip, extraction electrode lead-in wire.The one side of silicon pressure drag chip is and the high pressure chest of tested pressure communication that another side is the low-pressure cavity being communicated with atmosphere.At 4 P impurity resistance bars of circular silicon membrane sheet (N-type) localization diffusion and be connected into full-bridge, wherein two are positioned at compressive stress district, another two in tension district, with respect to diaphragm Central Symmetry.Silicon cylindricality sensitive element is also that resistor stripe is made in diffusion on the certain orientation of a certain crystal face of silicon cylinder, and the resistor stripe of the resistor stripe of two tension stress and another two compression chords forms full-bridge.Pressure transducer, when sensing different water level weight, is exported different magnitudes of voltage.Weight induction value and magnitude of voltage are linear, thereby the magnitude of voltage of exporting by processing just can be calculated weight, thereby draw accurate rainfall value.When the water in graduated cylinder 3 need to be emitted, open water drain valve 5.
