Description
Technical field
The utility model belongs to electrical metering device field, especially a kind of portable waterproof electronic scales.
Background technology
The development of modern society, has higher requirement to weighing technology.Electronic scales is with its compact conformation in recent years, weigh accurately, reading is directly perceived, easy to carry and obtain general application, along with the general electronic scales of continuous expansion of application can not meet reality need, waterproof type electronic scale just should need and give birth to, the waterproof electronic scale used in the market is all circuit part is sealed or adopts semi-enclosed structure and integral seal structure, the core component sensor of electronic scales is not then sealed, because sensor is generally aluminium matter, its moisture proof, anticorrosive property is poor, long-time use easily makes the surface of sensor be corroded, thus limit electronic scales measuring accuracy in harsh environments, application and serviceable life.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of to adopt Modern Sensor Technology, can detect in particular circumstances, all-sealed, moisture proof, anticorrosion, portable waterproof electronic scales that measuring accuracy is high.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of portable waterproof electronic scales, be made up of title body, LOAD CELLS, amplifier, A/D converter, single-chip microcomputer, alarm module, Keysheet module, LCD liquid crystal display screen, described title body is connected with LOAD CELLS; Described LOAD CELLS is connected with amplifier; Described amplifier is connected with A/D converter; Described A/D converter is connected with single-chip microcomputer; Described single-chip microcomputer is connected with LCD liquid crystal display screen, Keysheet module, alarm module.
And described LOAD CELLS is made up of the scale pan, scale pan support member and elastic body web member.
And described A/D converter adopts HX711 converter chip.
And described single-chip microcomputer adopts AT89S52 main control chip.
And described Keysheet module adopts matrix keyboard structure.
Advantage of the present utility model and good effect are:
1, the utility model LOAD CELLS adopts Modern Sensor Technology, can detect in particular circumstances, and all-sealed, moisture proof, anticorrosion, measuring accuracy are high, effectively eliminate personal error, solves electronic scales and measures short problem in inaccurate, serviceable life.
2, the utility model portable waterproof electronic scales has that startup self-detection, volume are little, accurate measurement, easy to carry, simple to operate, weighing speed is fast, union quality weighing function and calculation of price function, in one, can meet the user demand of commerce and trade and residential households.
Accompanying drawing explanation
Fig. 1 is that the utility model general system set-up connects block diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
As shown in Figure 1, a kind of portable waterproof electronic scales described in the utility model, be made up of title body, LOAD CELLS, amplifier, A/D converter, single-chip microcomputer, warning circuit, keyboard circuit, LCD liquid crystal display screen, described title body is connected with LOAD CELLS; Described LOAD CELLS is connected with amplifier; Described amplifier is connected with A/D converter; Described A/D converter is connected with single-chip microcomputer; Described single-chip microcomputer is connected with LCD liquid crystal display screen, Keysheet module, alarm module.
When weighed object is placed on the weighting platform claiming body, its quality is just by claiming body to be delivered to LOAD CELLS, LOAD CELLS is by the scale pan, scale pan support member and elastic body web member composition, scale pan supporting member its underpart adopts groove structure, when elastic body web member is connected with scale pan supporting member through sleeve pipe, the connecting portion of elastic body web member and scale pan supporting member is made to be positioned at inside the groove of scale pan supporting member, first the outer wall of scale pan supporting member plays the effect of blocking, the outside of sleeve pipe is blocked again again by the sealing shroud be arranged on elastic body web member, make elastic body web member, sleeve pipe, sealing shroud and scale pan supporting member form a labyrinth type waterproof construction, effective anti-sealing enters in LOAD CELLS.Then sensor produces electric signal thereupon, this signal is undertaken amplifying, changing through HX711 converter chip by amplifying circuit, and digital signal is transferred to single-chip microcomputer again, and single-chip microcomputer is after process accordingly, obtain weight and the amount of money of current alleged article, be then presented in LCD liquid crystal display screen.When weighing article body exceedes the maximum range of electronic scales, there will be overload sound and light alarm, prompting user, prevent from damaging instrument.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model is not limited to the embodiment described in embodiment; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
