Abstract
The invention discloses a piezoelectric electronic level meter, which comprises a shell and a rolling ball which is arranged in the middle of the shell. The piezoelectric electronic level meter is characterized in that: four piezoelectric sensors are arranged on the four sides of the rolling ball; the piezoelectric sensors can test an inclined angle according to the force which is applied by the rolling ball to the piezoelectric sensors; display screens are arranged on the shell on the two sides of the rolling ball; a control module and a power supply are arranged in the shell; and the piezoelectric sensor, the control module, the display screens and the power supply are connected through circuits. The piezoelectric electronic level meter can display the inclined angle through the display screens to help people adjust the angle, and has the advantages of simple structure, low cost and high precision.
Description
Technical field:
What the present invention relates to is a kind of piezoelectric electronic level meter.
Background technology:
At present, level meter has two kinds of air-bubble level and electrolevels, and horizontal and vertical glass envelope is housed in smooth base, in be filled with alcohol, and leave bubble, whether utilize bubble can often remain on the attribute inspection desktop of extreme higher position smooth; 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.Above level meter exists this that determining of measuring accuracy is low, cost the is high angle that can not directly show inclination arranged.
Summary of the invention:
The object of the invention 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, technical scheme of the present invention is as follows:
Piezoelectric electronic level meter, comprise housing, be arranged on the middle interior spin of housing, it is characterized in that, be provided with four piezoelectric sensors around the described spin, the angle of the acting force of piezoelectric sensor being tested inclination according to spin is provided with display screen on spin two side bodies, also be provided with control module and power supply in the described housing, connect by circuit between described piezoelectric sensor, control module, display screen and the power supply.
Principle of work of the present invention is, by the pressure that spin produces piezoelectric sensor, piezoelectric sensor transforms electric signal by pressure 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.
The present invention and prior art than the beneficial effect that has be earlier, and that the present invention has is simple in structure, cost is low, advantage of high precision, and can show the angle of inclination by display screen, thereby the help people go to adjust angle, have practicality widely.
Description of drawings:
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is a principle of work module map of the present invention.
Fig. 2 is a structural representation of the present invention.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
With reference to figure 2, piezoelectric electronic level meter of the present invention, comprise a cubical housing 1, square balance cylinder for spin 3 is housed in the middle of housing 1, around the spin 3 be the balance cylinder around four piezoelectric sensors 4 are installed, this piezoelectric sensor tight 4 pastes spin 3, tests the pressure of 3 pairs of piezoelectric sensors 4 of spin accurately.On the same one side of 3 liang of side bodies 1 of spin, left and right sides display screen 2 is installed, is used for showing the result of inclination.Control module 5 also is installed in housing 1, and this control module 5 can be the good single-chip microcomputer of programming, also can the MCU chip, be used for controlling whole device, and in housing 1 bonnet, be provided with power supply, this power supply is a charging accumulator, also can be dry cell.Described power supply, control module 5, display screen 2 and piezoelectric sensor 3 are connected by circuit.
As shown in Figure 1, when the present invention has inclination on the test object plane, spin will produce pressure F to the piezoelectric sensor 3 of a side of its inclination, piezoelectricity is converted into electric signal by sensor 3 according to pressure and sends control module 5 to, control module 5 by analysis and calculate, promptly, calculate the value of tilt angle theta, thereby the angle value that control module 5 is calculated shows its angle system and vergence direction by display screen 2 according to formula F=Gsin θ by the gravity and the flat inclination θ of spin 3.
The present invention and prior art than the beneficial effect that has be earlier, and that the present invention has is simple in structure, cost is low, advantage of high precision, and can show the angle of inclination by display screen, thereby the help people go to adjust angle, have practicality widely.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
