Description

Electronic scale

The utility model belongs to a kind of small-sized civil electronic scale.

The metering of scale accurately with easy to use, not only helps the user, the more important thing is the interests that can guarantee the consumer.The present steelyard that uses, the retailer is easy to cheating, gives short weight, and has damaged consumer's interests, therefore should advocate and promote the use of electronic scales.Electronic scales is directly perceived, and weight and price both parties can both see, because debugging needs input password retailer to can not do fraud on electronic scales, thereby has protected consumer's interests.But the electronic scales that the market is used mostly belongs to flat structure, and display window is below the scale pan, and the valuation scale then needs the window of weight, unit price, three separation of the amount of money, and it is very inconvenient that client observes the weight and the price of the article of oneself buying.Structure is not compact in addition, the price height, and large scale application has certain difficulty.

The purpose of this utility model is at the problems referred to above, provides that a kind of cost is low, compact conformation, observes electronic scale easily.

The purpose of this utility model realizes by following technical proposals, that is:

Electronic scale comprises display box, scale body, scale pan frame, the scale pan and electric part.

Its main points are: display box is positioned at a side of the scale pan, and respectively there is a window front and back on the display box, can show weight, unit price, total price etc. simultaneously.This set has not only reduced scale pan height widely, and observes very convenient.Display box is fixed on an end of scale body, and the scale body other end is the herringbone leg.At scale scale pan frame pilot hole and 2 sensor screw holes are arranged on one's body.Scale pan frame pilot hole is provided with the dustproof and waterproof lid, can guarantee that dirt can not enter the scale body.The fastening screw of scale pan frame passes center pit that dustproof and waterproof covers and inserts in the sensor web member in the scale body.Sensor is bolted in the scale body by two.

Electric part of the present utility model mainly adopts the microcomputer weighing system, and the central processing unit volume has only the area of soybean grain size, but integrated ten hundreds of logic circuit unit makes machine volume little, and computing and data processing function are complete.Electric part is arranged in the display box, is connected with operation keyboard, LCDs, sensor, power supply etc. by lead.The utility model is low in energy consumption, only 13 milliamperes of working currents, and rechargeable battery fills once electricity can work about half a year, brought convenience to the user.

Principle of work of the present utility model is as follows:

After putting into weight on the scale pan, the scale pan and scale pan frame are added in sensor one end with gravity, sensor bridge circuit 24, and output weighing signal after prime amplifier 14 amplifies, converts digital quantity to through A/D converter 15 again, is input to central processing unit CPU.CPU is made of computing and controller, and the digital signal of input is carried out various fundamental operations and logic discrimination.The weighing program, data processor, logic discrimination program, the various revision program that have prior establishment 16 li of memories.(seeing accompanying drawing 5) calls distinct program respectively and can realize various functions when put into weight or touch control keyboard respective keys in the scale pan, shows 26 as weight, unit price shows 27, the amount of money shows 28, and zero-bit, negative value, peeling, under-voltage show 29, corresponding sound equipment prompting 30.The concrete function division is as follows:

1, startup self-detection function:

By behind the start key, machine enters self check state and send hum simultaneously three, display screen shows complete 8 states, this moment, the operator can check whether various digital strokes have shortage, enter the state of weighing after 2 seconds, and machine is by automatic clear.

2, start blank panel discrimination function:

As leave weight in the hour indicator of starting shooting, when weight surpasses certain value, machine will send continuously and repeatedly pipe and shutdown automatically, have weight not drive machine in prompting operation person's dish.

3, manual zero setting function:

When the scale pan leaves residue after weighing, can be when causing machine that a small amount of indicated number is arranged before weighing by the zero setting key, the weight display field will be by zero setting.Heavier as weight, when surpassing 0.16kg, zero setting is invalid, and this kind situation belongs to needs peeling or start separately.

4, peeling function:

Be added with tare weight on the scale pan, perhaps put into a certain weight and do not wanted to shed, before continuing to claim certain goods, press the peeling key again, tare weight can be removed automatically, and weight is shown as zero.Put into certain goods, indicated number is this kind goods net weight, as takes away goods, sheds tare weight from the scale pan again, and the weight hurdle will show negative tare weight, again by once removing the peel the return-to-zero of key indicated number.

5, overload display alarm function:

When the goods put in the dish above the maximum capacity number, this chance is reported to the police automatically, and weight column number word goes out entirely, and the total charge hurdle demonstrates the printed words of OUE, sends continuously simultaneously to pipe, and till shedding overweight number, electronic scales does not generally allow overload.

6, accumulation function:

When several commodity of purchase of customer, carry out amount of money accumulation settlement and show, after a kind of commodity amount of money clearing of every title show, press " accumulative total " key, Add printed words (meaning of English addition) appear in the weight hurdle, the number of times that adding up appears in the unit price window, and total charge shows the accumulating sum number.

7, remove function:

The replacing client presses " removing " key when needing amount of money accumulative total storer, the zero clearing of unit price storer can be with unit price and the zero setting of amount of money window.

8, stable reading processing capacity:

This function can make reading when being subjected to precipitate interference unaffected remain unchanged moving.Have only when weight changes in the real dish just along with change.

9, the cipher control complete machine is set up and inner high number of divisions Presentation Function:

For making electronic scales can not do that fraud is careless to be adjusted, just can adjust after adopting the input password, and password to be producer be kept absolutely secret, the user does not grasp password and can not adjust.The input password can make machine enter inner high calibration show state again, in this state downward modulation complete machine tolerance journey and indicating value, to guarantee precision.

10, the power saving function of shutting down automatically:

Electronic scales continues one minute still no change when alleged weight comprises blank panel in the scale pan under open state, and machine will cut out automatically, prevent not the time spent or with after forget to shut down and cause battery to discharge for a long time.

11, the function of manually shutting down:

Touch by closing key, close on the mechanical horse.

12, undertension Presentation Function:

When non-maintaining rechargeable battery discharges into lower voltage limit, promptly display window is with displaying symbol during 5.4V, and the expression battery should charge at once.

13, charged state deixis:

This function adopts pandemic new technology, and fuzzy control principle can be judged level of charge by the degree red, that green light is bright.
