Abstract
The utility model discloses an electronic balance. The electronic balance comprises a pressure sensor, a signal amplification circuit, an analog-to-digital converter, and an MCU (micro control unit) which are connected in sequence, and further comprises an LCD display circuit, a power circuit, a functional key operating circuit, a data storage module and a wireless communication module which are respectively connected with the MCU. The electronic balance with the data storage function and the wireless transmission function can store mass of weight value data for users to inquire and analyze, and can transmit the stored mass of data to external equipment through a blue tooth module, a radio-frequency emission or an infrared module, thereby facilitating data reduction and analysis by users and being simple and easy to achieve.
Description
[technical field]
The utility model relates to weighing-appliance, relates in particular to a kind of electronic scale.
[background technology]
In the market, electronic scales has been not strange product, but because of numerous advantages such as it have robotization control, digital intuitive display, accuracy height, resolution height, volume is little, maintenance is simple, installation is simple, has been subjected to widespread use.As shown in Figure 1, the inside of existing electronic scale generally comprises: MCU, pressure transducer, signal amplification circuit, analog to digital converter, LCD display and LCD driving circuit, power circuit, function button function circuit, oscillatory circuit, its workflow is: when object is placed on the scale pan, pressure is applied to pressure transducer, this pressure transducer generation deformation, thereby impedance is changed, driving voltage is changed, the simulating signal of a variation of output; This simulating signal outputs to analog to digital converter through the signal amplification circuit amplification; Analog to digital converter converts thereof into the digital signal of being convenient to handle again and outputs to MCU and carry out s operation control; MCU operation result the most at last outputs to LCD display and shows.Pressure transducer of a great variety has high-precision Wheatstone bridge resistance sensor yet adopt usually at present.But, above-mentioned electronic scales does not generally have data storage function and data-transformation facility, and then can not store the gravimetric value information that the user gets up to weigh for a long time and obtains, and can not be connected, upload data with equipment such as PC, mobile phone, Internet servers, can not manage analysis all wt value information.Though can adopt cable that electronic scales is connected with external unit, connection cable is the product that easily lose, and connects inconvenient.So pressing for a kind of electronic scale of data storage and data-transformation facility of supporting meets the need of market.
[summary of the invention]
