Abstract
The invention relates to the technical scheme of electronic scales, in particular to a multifunctional electronic scale based on a single-chip microcomputer. The multifunctional electronic scale based on the single-chip microcomputer comprises a pressure sensor, a signal filtering and amplification processor, an A/D converter, the single-chip microcomputer, a keyboard control portion and an LCD, wherein the output of the pressure sensor is connected with the signal filtering and amplification processor, the output of the signal filtering and amplification processor is connected with the A/D converter, the output of the A/D converter is connected with the single-chip microcomputer, the output of the single-chip microcomputer is connected with the LCD, and the output of the keyboard control portion is connected with the single-chip microcomputer. The multifunctional electronic scale based on the single-chip microcomputer is simple in structure, the capacity of human-machine exchange is enhanced, the design requirement is met, a shopping list, information of weighed articles and related content can be displayed, and meanwhile, maintenance is convenient to perform.
Description
Technical field
The present invention relates to a kind of Multifunctional electronic scale, particularly relate to a kind of SCM Based Multifunctional electronic scale.
Background technology
Electronic scales is electronic scale conventional in daily life, is widely used in supermarket, big and middle market, logistics distribution center.It is that the traditional mechanical type of principle weighs instrument that electronic scales instead of with lever balance in structure and principle.Compare traditional mechanical type and weigh instrument, electronic scales has that weighing precision is high, installation volume is little, applied range, be easy to operation.The weighing instrument used in the market, or complex structure, or run unreliable, and cost is high, and precision stability is bad, and the levelling time is long, and consumable accessory is many, maintenance difficult, and installed capacity is large, and greatly, production cost is high in energy resource consumption.
Summary of the invention
The technical problem to be solved in the present invention is: the weighing instrument used in the market, or complex structure, or run unreliable, and cost is high, precision stability is bad, the levelling time is long, and consumable accessory is many, maintenance difficult, installed capacity is large, energy resource consumption is large, and production cost is high, provides a kind of SCM Based Multifunctional electronic scale.
In order to overcome the defect existed in background technology, the technical solution adopted for the present invention to solve the technical problems is: this SCM Based Multifunctional electronic scale comprises pressure transducer, signal filtering amplification processor, A/D converter, single-chip microcomputer, Keyboard Control and LCD display, the output connection signal filter amplifying processing device of described pressure transducer, the output of signal filtering amplification processor connects A/D converter, the output of A/D converter connects single-chip microcomputer, the output of single-chip microcomputer connects LCD display, and the output of Keyboard Control connects single-chip microcomputer.
The invention has the beneficial effects as follows: the structure of this SCM Based Multifunctional electronic scale is simple, not only strengthen the ability of human-computer exchange, and meet design requirement, the related contents such as shopping list, the object information that weighs can be shown, safeguard also more convenient simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Embodiment
Fig. 1 is structural representation of the present invention, figure comprises pressure transducer, signal filtering amplification processor, A/D converter, single-chip microcomputer, Keyboard Control and LCD display, it is characterized in that: the output connection signal filter amplifying processing device of described pressure transducer, the output of signal filtering amplification processor connects A/D converter, the output of A/D converter connects single-chip microcomputer, the output of single-chip microcomputer connects LCD display, and the output of Keyboard Control connects single-chip microcomputer.
During this SCM Based Multifunctional electronic scale front end signal process, select the measure such as amplification, A/D conversion, in display, especially adopt the LCD display with character picture and text showing function.This structure not only strengthens the ability of human-computer exchange, and meets design requirement, and can show the related contents such as shopping list, the object information that weighs.
