Description
Technical field
The utility model relates to a kind of piezoelectric electronic level meter.
Background technology
At present, level meter has two kinds of air-bubble level and electrolevels, wherein, in the smooth base of air-bubble level horizontal and vertical glass envelope is housed, in be filled with alcohol, and leave bubble, whether utilize bubble can often remain on the attribute inspection desktop of extreme higher position smooth; And the cardinal principle of electrolevel has two kinds of inductance type and condenser types, changes the size of inductance or electric capacity by helve hammer, thereby judges the desktop angle of inclination.What above level meter existed that this has that measuring accuracy is low, cost is high can not directly show the shortcoming of the angle of inclination, thereby has brought inconvenience to the user, so level meter remains further to be improved.
Summary of the invention
The utility model purpose provides that a kind of cost is low, precision is high and can accurately show the piezoelectric electronic level meter at angle of inclination, is used for remedying the deficiencies in the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
Piezoelectric electronic level meter, comprise housing, be arranged on the middle interior spin of housing, it is characterized in that, be respectively equipped with a pressure transducer around the described spin, the angle according to spin is tested inclination to the acting force of pressure transducer is respectively equipped with a display screen on spin two side bodies, also be provided with the control module and a power supply of the whole device operation of a control in the described housing, described pressure transducer, display screen and power supply all are connected with control module by circuit.
According to described piezoelectric electronic level meter, wherein, described display screen is a LCDs.
According to described piezoelectric electronic level meter, wherein, described display screen is separately positioned on the both sides of spin.
According to described piezoelectric electronic level meter, wherein, described pressure transducer is a piezoresistive pressure sensor.
Principle of work of the present utility model is, the pressure that spin produces pressure transducer, pressure transducer transform electric signal by pressure again and sends control module to, and control module is by analyzing and handle, thereby sends display screen to, is used for showing the angle of its inclination.
Pressure transducer in the utility model adopts the Hui Sitong principle, foil gauge is bonded on the generation mechanics strain matrix closely by special bonding agent, when the stressed generation STRESS VARIATION of matrix, resistance strain gage also produces deformation together, the resistance of foil gauge is changed, be added in ohmically voltage and change thereby make; This foil gauge is the strain bridge that resistance is formed, because the change in resistance that this foil gauge produces when stressed is less usually, voltage changes also corresponding less, is converted into electric signal output so change after back voltage amplifies through amplifying circuit.
The beneficial effect that the utility model compared with prior art has is, the utlity model has simple in structure, cost is low, advantage of high precision, and can show the angle of inclination by display screen, thus help people to go to adjust angle, have practicality widely.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a principle of work module map of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to figure 1 and Fig. 2, piezoelectric electronic level meter of the present utility model, the housing 1 that comprises a rectangular parallelepiped, square balance cylinder for spin 3 is housed in the middle of housing 1, around the spin 3 be the balance cylinder around four pressure transducers 4 are installed, this pressure transducer 4 is close to spin 3, tests the pressure of 3 pairs of pressure transducers 4 of spin accurately.On the same one side of 3 liang of side bodies 1 of spin, be separately installed with display screen 2, be used for showing the result of inclination.In this enforcement, display screen is a LCDs, the angle of inclination of more clear observation post test.
In the utility model, control module 5 is installed also in housing 1, this control module 5 can be the single-chip microcomputer of the good certain program of programming, also can be the MCU chip, is used for controlling whole device operation.Be provided with power supply in the bonnet of housing 1, this power supply is a charging accumulator, also can be dry cell, and is easy for people to use.In the present embodiment, described power supply, control module 5, display screen 2 and pressure transducer 4 all are connected with control module by circuit.
Again referring to Fig. 1, pressure transducer 4 in the utility model is a piezoresistive pressure sensor, this piezoresistive pressure sensor 4 adopts the Hui Sitong principle, foil gauge is bonded on the generation mechanics strain matrix closely by special bonding agent, when the stressed generation STRESS VARIATION of matrix, resistance strain gage also produces deformation together, and the resistance of foil gauge is changed, and is added in ohmically voltage and changes thereby make; In the present embodiment, this foil gauge is the strain bridge that resistance is formed, because the change in resistance that this foil gauge produces when stressed is less usually, voltage changes also corresponding less, so this strain bridge output terminal also connects amplifying circuit, change being converted into electric signal output after back voltage amplifies through first amplifying circuit.
When the utility model has inclination on the test object plane, spin 3 will produce pressure F to the pressure transducer 4 of a side of its inclination, pressure transducer 4 is converted into electric signal according to pressure and sends control module 5 to, control module 5 by analysis and calculate, promptly by the gravity and the flat inclination θ of spin 3, calculate the value of tilt angle theta according to formula F=Gsin θ, thereby the angle value that control module 5 is calculated shows its angle system and vergence direction by display screen 2.
Based on above-mentioned, the utlity model has simple in structure, cost is low, advantage of high precision, and the angle that can show by display screen, thus help people to go to adjust angle, have practicality widely.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
