Abstract
The utility model provides an intelligent weight meter; a storage chip and a clock chip are additionally adopted based on the ordinary weight meter that is formed by sequentially connecting a weighing sensor, a controller and a display module in series; the storage chip and the clock chip are mutually connected in parallel and controlled by the controller; the two chips either can be physically independent or can serve as a part of the controller and be integrated with the controller; the controller reads time data in the clock chip while acquiring weight data; and the weight data and the time data are stored in the storage chip in certain formats. Four button switches arranged on the surface of the weight meter are used for adjusting the time of the clock chip and selecting weighing objects.
Description
Technical field:
The utility model relates to a kind of device of measuring body weight.
Background technology:
The body weight instrument is the common tool of a lot of families.Present most of body weight instrument is divided into pointer-type and digital two classes, and pointer-type is to experience the big or small of body weight and indicate with pointer by spring; Digital is to show on display screen through after the analog to digital conversion by sensor.Existing body weight instrument generally is connected successively by LOAD CELLS, controller and display module.The body weight signal is converted into digital signal through LOAD CELLS, under controller action, shows on display module.No matter which kind of body weight instrument does not all have the function of preserving weight data and date data automatically.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of intelligent body weight instrument, each weight data and date of measuring is preserved automatically, and can be transferred on the computing machine by interface.By analysis to these data, can help the correct body weight change rule of understanding oneself of end user effectively, reach salubrious purpose.
The technical scheme that its technical matters that solves the utility model adopts is: increased the storage chip of store data and be used for the clock chip of timing on the basis that is connected in series the ordinary electronic scale that is constituted by LOAD CELLS, controller and display module successively, they are with the parallel way control of controlled device simultaneously.These two kinds of chips can be independently physically, and the part and the controller that also can be used as controller integrate.At body weight instrument face four pushbutton switches are set.
The principle of work of this body weight instrument is, at first the weight of measured object is changed into electric signal by weight sensor, after amplifying, operational amplifier delivers to the input port of analog to digital converter, digital signal after the conversion is sent to the input end of controller, through internal processes control, read the time data in the clock chip simultaneously, at last these two classes data are delivered to memory chip stores.
The beneficial effects of the utility model are, because in parallel storage chip and clock chip can be stored weight data and corresponding date data automatically, thereby can help the end user to understand the body weight change situation effectively in controller, adjust rule of life, promote healthy better.
Description of drawings:
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the control program block diagram of the intelligent body weight instrument that the utility model proposed.
Among the figure, 1-weight sensor, 2-operational amplifier, 3-analog to digital converter, 4-clock chip, 5-controller, 6-storage chip, 7-displaying block, 8-data-interface, 9-pushbutton switch, 10-pushbutton switch, 11-pushbutton switch, 12-pushbutton switch.
Embodiment:
Further describe concrete structure of the present utility model below in conjunction with accompanying drawing.
Shown in Figure 1, the utility model converts human body weight to electric signal at common body weight instrument by weight sensor 1, after amplifying, operational amplifier 2 delivers to analog to digital converter 3 conversions, weight data after the conversion is delivered to controller 5, controller is delivered to demonstration in the displaying block 7 after receiving weight data, on the basis that above-mentioned device is in series successively, also comprise storage chip 6 and clock chip 4, they are connected in parallel on the controller 5.Controller 5 reads the time data in the clock chip when obtaining weight data, and weight data and time data are left in the storage chip with certain form; The pushbutton switch 9 to 12 of body weight instrument face has two effects, and the one, be used for adjusting the time number of clock chip, the 2nd, be used for selecting the object of weighing.Data-interface 8 is used for and external computer system swap data, and these data can be by the in time correct health status of understanding measured people of scientific analysis.The model of each device is respectively body weight sensor: Turck series; Operational amplifier: LM324; Analog to digital converter: ADC series or LM331; Clock chip: DS series or PCF family chip; Controller: 51 series or 96 series monolithics; Memory chip: E
2PROM; Displaying block is the liquid crystal display piece; Data-interface is USB interface or serial line interface.
Claims (2)
1. intelligent body weight instrument is connected in series successively by LOAD CELLS, controller and display module and constitutes, and it is characterized in that having increased storage chip and clock chip with parallel way on controller, at body weight instrument face four pushbutton switches is set.
2. according to the described intelligent body weight instrument of claim 1, it is characterized in that described storage chip is E
2PROM, clock chip are DS family chip or PCF family chip.
