Abstract

The utility model relates to a USB electronic scale for offices, which comprises an electronic scale body, a weighing sensor, an A/D convertor connected with the weighing sensor, a main control unit connected with the A/D convertor, a USB interface arranged on the electronic scale body and a computer. The weighing sensor, the A/D convertor and the main control unit are arranged in the electronic scale body, and the computer is connected with the main control unit through a USB interface. The USB electronic scale has the advantage that a corresponding power supply device, a corresponding interface display screen and corresponding operation buttons are not required to be arranged on the electronic scale body, so that the electronic scale has the characteristics of convenient connection and small occupied space.

Description

A kind of office uses the USB electronic scales

[technical field]

The utility model relates to a kind of electronic scales, relates in particular to a kind of office and uses the USB electronic scales.

[background technology]

Electronic scales is widely used because of characteristics such as its light sensitivities; Existing traditional electronic scales contains the electronic scales fuselage usually; Be provided with LOAD CELLS, A/D converter and main control unit in this electronic scales fuselage, and generally be provided with interface screen, operation push-button, serial ports and outlet etc. on this electronic scales fuselage.

Utilizing computer office field,, the volume of product is being proposed harsh more requirement because the desk tops space is limited.And traditional electronic scales generally is through serial ports and computer (PC) communication, and with battery or adapter electronic scales is supplied power, and through the operation of the operation push-button on the electronic scales fuselage; And in its interface screen demonstration related data, though complete function, volume ratio is huger; Connecting line is more; Obviously, for office user, this type of electronic scales very is not fit to them to be used.

[utility model content]

The USB electronic scales that the utility model technical matters to be solved is to provide a kind of convenience in the office that utilizes the computer office, to use, not only easy to connect, and also it is little to take up room.

The utility model solves the problems of the technologies described above through following technical scheme: a kind of office uses the USB electronic scales; Comprise that the main control unit, that A/D converter, that an electronic scales fuselage, a LOAD CELLS, are connected with LOAD CELLS is connected with A/D converter is located at a USB interface and a computer on this electronic scales fuselage; Said LOAD CELLS, A/D converter and main control unit all are located in this electronic scales fuselage, and this computer expert crosses said USB interface and is connected with main control unit.

A kind of office of the utility model is with the beneficial effect of USB electronic scales: through being connected of computer in USB interface and the office; Make electronic scales directly to obtain power supply from computer; And can realize the function of interface screen and operation push-button on the conditional electronic scale through computer; Thereby make to need not to be provided with power supply device, interface screen and operation push-button on the electronic scales fuselage, and then can be implemented in that the electronic scales that uses in the office is easy to connect, little purpose takes up room.

[description of drawings]

Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.

Fig. 1 is the one-piece construction synoptic diagram of a kind of office of the utility model with the USB electronic scales.

Fig. 2 is the fundamental diagram of the utility model office with the USB electronic scales.

[embodiment]

See also Fig. 1 and Fig. 2; A kind of USB power supply of the utility model electronic scales; Comprise A/D converter 5 that an electronic scales fuselage 1, is located at USB interface 2, a computer (PC) 3, a LOAD CELLS 4, on this electronic scales fuselage and is connected with LOAD CELLS 4, and the main control unit 6 that is connected with A/D converter 5; Said LOAD CELLS 4, A/D converter 5 and main control unit 6 all are located in this electronic scales fuselage 1, and this computer 3 is connected with main control unit 6 through said USB interface 2.

During the utility model work: earlier USB interface 2 and in running order computer (PC) 3 are connected; Then get into duty after the electronic scales startup self-detection; The article of weighing when the article of weighing place on the electronic scales convert gravity into via weight sensor 4 simulating signal of voltage or electric current; This simulating signal converts digital signal into via A/D processor 5 afterwards; Digital signal is gone forward side by side the row operation processing to obtain the weighing value by main control unit 6 filtering, through USB interface 2 this weighing value is sent to computer (PC) 3 then, and the corresponding software in the computer (PC) 3 has carried out receiving and showing to it; In addition, computer (PC) 3 can send dependent instruction with operations such as the zero setting in the realization weighing process, peeling, unit conversion, calibrations to main control unit 6 through USB interface 2.

To sum up; The utility model is connected through ready-made computer in USB interface and the office; Make electronic scales directly to obtain power supply from computer; And can realize the function of interface screen and operation push-button on the conditional electronic scale through computer, thereby make and need not to be provided with power supply device, interface screen and operation push-button on the electronic scales fuselage, and then make the electronic scales that in office, uses not only easy to connect and take up room little.

Claims

1. an office uses the USB electronic scales; Comprise that the main control unit and that A/D converter, that an electronic scales fuselage, a LOAD CELLS, are connected with LOAD CELLS is connected with A/D converter is located at the USB interface on this electronic scales fuselage; And said LOAD CELLS, A/D converter and main control unit all are located in this electronic scales fuselage; It is characterized in that: also comprise a computer, this computer expert crosses said USB interface and is connected with main control unit.
