Description
Technical field
The utility model belongs to the electronic scales field, relates in particular to a kind of digital intelligent electric scale.
Background technology
Weighing device is not only provides the monomer of weight data instrument, and as an ingredient of industrial control system and business management system, so electronic scales just needs higher technical requirement as a kind of advanced person's weighing device.
Domestic electronic weighing technology reaches the level of the mid-90 in 20th century in the world basically, and in the domestic electronic scales market, it is 10mg that the electronic scales precision of 1009 left and right sides ranges is generally 0.019.On research method, the principle of work of electronic weighing system generally is with the quality or the size of power that act on the carrier, is changed to electric signal through the pressure transducer dress, and handles this electric signal through control circuit.
The accuracy and the reliability of electronic scales are all undesirable at present.The general operation of many connecting plates and the little technology of cutting of adopting, the PCBA plate ruptures easily, makes casting die operating personnel's efficient reduce.Courage electric capacity on the mu balanced circuit is withstand voltage too small, is prone to punch-through, make the electronic scales life-span significantly reduce, and the speed of weighing is unhappy, and cost is higher.
The utility model content
The purpose of the utility model is to provide a kind of digital intelligent electric scale, and the PCBA plate that is intended to solve present electronic scales ruptures easily, makes casting die operating personnel's efficient reduce.Courage electric capacity on the mu balanced circuit is withstand voltage too small, is prone to punch-through, make the electronic scales life-span significantly reduce, and the speed of weighing is unhappy, the cost problem of higher.
The utility model is to realize like this; A kind of digital intelligent electric scale; The signal amplifying part branch that this electronic scales comprises the signals collecting part that is made up of LOAD CELLS, be made up of prime amplifier, the analog to digital conversion part that constitutes by analog to digital converter, the Single-chip Controlling part that constitutes by single-chip microcomputer, by connecing the man-machine interface that a constitutes part and, 10 μ F/25V courage electric capacity being installed on the mu balanced circuit of the sensing arithmetical unit of said electronic scales by the man-machine coupling part that keyboard, display constitute.
Further, said electronic scales is equipped with surface-mounted integrated circuit.
The electronic scales that the utility model provides has adopted withstand voltage courage electric capacity, has avoided punch-through, has improved serviceable life, but the eliminating defective products of simple and fast, the test duration shortens, and cost reduces.In addition, the electronic scales that provides of the utility model embodiment has been eliminated the possibility of the PCBA plate fracture of circuit board in the past with surface-mounted integrated circuit.
Description of drawings
Fig. 1 is the structural representation of the digital intelligent electric scale that provides of the utility model.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 shows the structural representation of the digital intelligent electric scale that the utility model embodiment provides.For the ease of explanation, only show the part relevant with the present invention.
The signal amplifying part branch that this electronic scales comprises the signals collecting part that is made up of LOAD CELLS, be made up of prime amplifier, the analog to digital conversion part that constitutes by analog to digital converter, the Single-chip Controlling part that constitutes by single-chip microcomputer, by the man-machine coupling part that connects the man-machine interface that a constitutes part and constitute by keyboard, display.
The courage electric capacity that is equipped with on the mu balanced circuit of the sensing arithmetical unit of this electronic scales on the 10 μ F/25V courage capacitance voltage stabilizing circuit has adopted 10 μ F/25V electric capacity, has strengthened breakdown characteristics.
As the preferred version of the utility model embodiment, electronic scales is equipped with surface-mounted integrated circuit.
Utilize LOAD CELLS to obtain external weights information; After prime amplifier amplifies signal; Utilize analog to digital converter to become the analog signal conversion of input digital signal to handle to deliver to single-chip microcomputer; Single-chip microcomputer is accepted outside various data and the control information of sending to, through computing and processing, delivers to outside to realize that demonstration waits needs then.The man-machine interface parts are accomplished by the man-machine interface circuit with the connection of host circuit.
When commodity were put on the scale pan, the weight resistance strain type sensor under the scale pan produced an electric signal, and the power of signal is that the size with commodity weight changes; This signal is after amplifying circuit amplifies; Send into the A/D conversion chip and carry out analog to digital conversion, the digital quantity after the conversion heavily is directly proportional with thing, gets into single-chip microcomputer again through data processing; Single-chip microcomputer produces one group of data that satisfy display requirement, delivers to display circuit and demonstrates actual weight.On the other hand, cargo price is sent into single-chip microcomputer through keyboard scanning circuit, through data processing, delivers to display circuit and demonstrates cargo price.Thing is heavy to produce total price with unit price through computing, also on display circuit, shows.
The electronic scales that the utility model embodiment provides has been eliminated the possibility of the PCBA plate fracture of circuit board in the past with surface-mounted integrated circuit, has avoided punch-through, has improved serviceable life, but the eliminating defective products of simple and fast, the test duration shortens, and cost reduces.Thereby stability and reliability are improved.Make that the application performance trend of electronic scales product is more comprehensive, more can satisfy the demand in market.Courage electric capacity on the mu balanced circuit adopts 10 μ F/25V electric capacity, has strengthened breakdown characteristics, is not prone to punch-through, make the electronic scales life-span increase greatly, and the speed of weighing is fast, and cost reduces.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
