Abstract
An alarm rain gauge comprises a water holding drum, wherein an upper end of the water holding drum is provided with a rain holding opening, and the water holding drum is provided with scale marks. A water level sensor is arranged in the water holding drum and is connected with an alarm. The water level sensor comprises a linear hall device, wherein a floater provided with a magnet is arranged on the linear hall device. A processor module is connected with the water level sensor and the alarm. Through utilization of the linear hall element, the alarm rain gauge utilizes features of the linear hall device to perceive the size of a magnetic field and therefore the height of water level can be accurately measured. Meanwhile, an upper computer software can be used alone to correct errors, and therefore the alarm rain gauge solves the problems of installment errors and process errors in the prior art, and is stable in performance and free of maintenance.
Description
Technical field
The utility model relates to a kind of rain gage, particularly a kind of warning rain gage.
Background technology
Existing rain gage has only the function of metering rainfall, and so when the flood rainfall takes place, can not in time report to the police, there is potential safety hazard in the function of not taking precautions against flood.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of warning rain gage, uses the linear Hall components and parts, thereby utilizes the size in the characteristic perception magnetic field of linear hall-effect device precisely to draw the height of water level.Simultaneously can carry out error is revised through upper computer software separately, solve the alignment error of prior art existence and the problem of fabrication error, freedom from repairs stable and reliable for performance.
The above-mentioned purpose of the utility model is to realize through such technical scheme: the warning rain gage, comprise the tube that is filled with water, and the tube upper end that is filled with water is provided with holds the rain mouth, and the tube that is filled with water is provided with scale mark, is provided with water level sensor in the said tube that is filled with water, and water level sensor connects alarm.
Said water level sensor comprises linear hall-effect device, and linear hall-effect device is provided with the float of a magnet carrier.
Said water level sensor connection processing device module, processor module connects alarm.
Said processor module connects LCDs.
A kind of warning rain gage of the utility model, thus utilize the size in the characteristic perception magnetic field of linear hall-effect device precisely to draw the height of water level.And through the processor module Based Intelligent Control, carry out error is revised through upper computer software, solved the alignment error that rain gage exists in the prior art and the problem of fabrication error.This rain gage sound construction, volume are little, in light weight, and the life-span is long, and power consumption is little, vibration resistance, the pollution or the corrosion of not being afraid of dust, greasy dirt, steam and salt fog etc.Has installation, easy to maintenance, flexible operation, stable and reliable operation, advantage of high precision.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the utility model warning rain gage structural representation.
Fig. 2 is the Hall effect schematic diagram.
Embodiment
As shown in Figure 1, the warning rain gage comprises the tube 1 that is filled with water, and tube 1 upper end that is filled with water is provided with holds rain mouth 2, and the tube 1 that is filled with water is provided with scale mark, as graduated scale.Be provided with water level sensor 3 in the said tube 1 that is filled with water, water level sensor 3 connects alarm.
Said water level sensor 3 comprises one group of linear hall-effect device 4, and linear hall-effect device 4 outsides are provided with the float 5 of a magnet carrier.Be set to 12 grades, the scale mark on the corresponding respectively different tubes 1 that are filled with water.
Said water level sensor 3 connection processing device modules, processor module connects alarm.Said processor module connects LCDs.
When water level changed in the tube 1 that is filled with water, the position also corresponding meeting of float 5 in the tube 1 that is filled with water changed.According to hall principle, the Hall components and parts can induce surrounding magnetic field and change, utilize linear suddenly and the characteristic of sensor: output voltage and externally-applied magnetic field intensity are linear, and is as shown in Figure 2.In the magnetic induction density scope of B1～B2, the better linearity degree is arranged; Thereby can draw U1 ~ U2 potential difference (PD) of this moment; And reading and changing through processor module; In processor module, carry out being transformed into the rainfall height after a series of algorithm, the altitude range according to above-mentioned three types of warning rainfall compares again, the action of which warning that responds.
