Description
Technical field
The present invention relates to electronic information technical field, more particularly to a kind of electronic scale.
Background technology
With developing rapidly for science and technology, at present, use of the electronic table scale in commerce and trade is fairly common, but exists
Larger limitation：Volume is big, high cost, inconvenient to carry, application places are restricted.Existing portable balance is for steelyard or with bullet
Spring, stretcher strain come realize metering spring scale, resident use substantially steelyard.Spring pan scale manufacturing process requirement compared with
Height, the fatigue problem of spring cannot be solved thoroughly, once exceeding spring limit, spring scale will produce very big error, with
To damaging, the accuracy and reliability weighed are had influence on, simply a kind of temporary transient substitute, is also put into the row gradually cancelled
Row.
Therefore need to provide a kind of new electronic scale to avoid drawbacks described above.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of electronic scale, small volume, accurate measurement, carrying side
Just, disclosure satisfy that the use demand of commerce and trade and residential households.
A kind of electronic scale, the electronic scale includes controller part, collection measurement part, data display unit, keypad portion
Divide and circuit power part：
The industry collection measurement part is to detect pressure signal using weighing sensor, obtains faint voltage signal, is sent
A/D converter, digital output is converted into by analog quantity；
The controller part receives the data signal from A/D converter output, by complicated computing, numeral is believed
Number the actual weight signal of object is converted to, and be stored in memory cell；
Data display unit realizes display function as needed.
Preferably, the controller part can also be scanned by the control to expansion I/O to keyboard, then be led to
Cross keyboard and dissipate carryover sequence, whole system is controlled.
Preferably, the controller uses STC89C52 single-chip microcomputers.
Preferably, the weighing sensor uses CZL-A resistance strain type sensors.
Technical scheme has the advantages that：
A kind of electronic scale that the present invention is provided, it is small volume, accurate measurement, easy to carry, disclosure satisfy that commerce and trade and residence
The use demand in home front yard.
Specific embodiment
In order to have a clear understanding of technical scheme, its detailed structure will be set forth in the description that follows.Obviously, originally
Simultaneously deficiency is limited to specific details appreciated by those skilled in the art for the specific execution of inventive embodiments.Preferred reality of the invention
Apply example to be described in detail as follows, except these for describing in detail implement exception, there can also be other embodiment.
A kind of electronic scale of the present embodiment, its system is made up of 5 parts：Controller part, collection measurement part, data show
Show part, keyboard portion and circuit power part；Collection measurement part is to detect pressure signal using weighing sensor, obtains micro-
Weak electric signal (the design is voltage signal), send A/D converter, and analog quantity is converted into digital output.Controller part
Receive the data signal from A/D converter output, by complicated computing, convert digital signals into the actual weight of object
Signal, and be stored in memory cell.Controller can also be scanned by the control to expansion I/O to keyboard, and
Carryover sequence is dissipated by keyboard afterwards, whole system is controlled.Data display unit realizes display function as needed.
The controller uses STC89C52 single-chip microcomputers, the weighing sensor to use CZL-A resistance strain type sensors；
The present invention uses CZL-A resistance strain type sensors, and its maximum range is 10Kg. weighing sensors by combined type S type girder constructions
And type metal foil type strain gauge is constituted, with overload protection arrangement.Such as suppress the influence of temperature change due to Wheatstone bridge tool,
Suppress interference, compensation is the advantages of facilitate, so the sensor accuracy class is high, good temp characteristic, steady operation and other merits, extensively
The primary instrument of dynamic and static measurement and various electronic scales for various structures.The weighing sensor is main by elastomer, resistance
Foil gauge cable etc. is constituted.
Keyboard portion uses matrix keyboard：The characteristics of matrix keyboard is that detection line is divided into two groups, and one group is line,
One group of alignment, button is placed on the crosspoint of line and alignment.Such as 4 × 4 matrix keyboards can install 16 keys altogether, but only
Need 8 p-wires.When the quantity of keyboard is more than 8, matrix keyboard is typically all used, so, 16 buttons use 4 × 4
Matrix keyboard, another reset key is realized using free-standing button.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention rather than its limitations, to the greatest extent
Pipe has been described in detail with reference to above-described embodiment to the present invention, and those of ordinary skill in the art still can be to this hair
Bright specific embodiment is modified or equivalent, these without departing from spirit and scope of the invention any modification or
Equivalent, is applying within pending claims.
