Abstract
The utility model discloses a character display nutritious scale, which comprises an upper cover, a lower cover, a scale pan and a scale pan bracket. A character display device and an input keyboard are installed on the upper cover; the scale pan bracket is connected with a sensor which is connected with a signal processing circuit. The utility model uses a micro computer to control that an electronic scale weighs and simultaneously directly figures out various nutritious ingredients in food through the identification of numbers, and displays with characters by the character display device, which is visual and convenient.
Description
The utility model relates to a kind of scale.
Along with the raising of The development in society and economy and people's living standard, people more pay attention to the vital role that dietetic nutrition is risen in life process, so the scientific important content that has become the human modern life of diet.Existing scale structure is limit, and can not make things convenient for the composition that intuitively reflects food.
The purpose of this utility model is to provide a kind of literal of alleged food component that can intuitively reflect to show the nutrition scale.
Technical solution of the present utility model is:
A kind of literal shows the nutrition scale, comprises loam cake, lower cover, the scale pan, scale pan support, and its difference with prior art is: on cover and adorn character display apparatus and input keyboard, scale pan support is connected with sensor, sensor is connected with signal processing circuit.
A central microprocessor is arranged in signal processing circuit, central microprocessor is connected with amplifier through A/D converter, amplifier is connected with sensor, and central microprocessor also is connected with character display apparatus, input keyboard, and other has power circuit to be connected with above-mentioned each circuit.
The utility model utilizes the electronic scales of microcomputerized control when weighing, and by the numbering identification, various nutritions in the food is directly calculated, and shown by the literal display with literal, and is directly perceived, convenient.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the front view of an embodiment of the utility model.
Fig. 2 is the view after Fig. 1 embodiment removes loam cake.
Fig. 3 is the side view of Fig. 2.
Fig. 4 is the functional-block diagram of the signal processing circuit of Fig. 1 embodiment.
Fig. 5 is the circuit diagram of Fig. 1 embodiment.
A kind of literal shows the nutrition scale, comprises loam cake 1, lower cover 2, the scale pan 3, scale pan support 4, dress character display apparatus 5 and input keyboard 6 on the loam cake 1, and scale pan support 4 is connected with sensor 8, and sensor 8 is connected with signal processing circuit.
A central microprocessor 9 is arranged in signal processing circuit, central microprocessor 9 is connected with amplifier 11 through A/D converter 10, amplifier 11 is connected with sensor 8, and central microprocessor 9 also is connected with character display apparatus 5, input keyboard 6, and other has power circuit 7 to be connected with above-mentioned each circuit.
Comprise central microprocessor circuit single-chip microcomputer IC2 (MCU) in Fig. 5 circuit, A/D converter, amplifying circuit IC1 (LM324), U1, LCD LCD, keyboard circuit CN2, power supply IC3, resistance R 1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, R19, R20, R21, R22, R23, R24, R25, R26, R27, VR1, VR2, triode Q1, Q2, Q3, Q4, Q5, diode D1, D2, D3, D4, ZD1, capacitor C 1, C2, C3, C4, C5, C6, C7, crystal oscillator X1, switch J1, J2, J3 etc., during work, the voltage signal of sensor output is fainter, by delivering to by U1C after IC1 (LM324 U1A) amplification, U1D carries out the A/D conversion, analog voltage signal is transformed into digital signal, enter single-chip microcomputer IC2 (MCU), MCU is according to the variable quantity of numeral, determine weight, and the current potential content by the nutrient ingredient of food that pre-deposits, reference numeral according to the keyboard input, determine the concrete net content of each nutriment in the food, and on LCD, show.
