Abstract
The utility model relates to an electronic loadcell scale, comprising a scale body for measuring the weight of an object to be weighted and a control device for inputting an operating instruction, wherein, the scale body is provided with a control interface, the control device is connected to the scale body by the control interface. The utility model controls the electronic loadcell scale by the external control device, thereby not contacting the scale body in the control process and avoiding the degradation of the performance of the electronic loadcell scale caused by the control operation. Moreover, the control device is separated from the scale body; therefore, the scale body can have a rotproof and firm as well as durable housing to protect the components inside the scale body preferably and correspondingly prolongs the service life of the utility model; in addition, when being damaged, the control device can be conveniently replaced and can be protected by some methods easily.
Description
Technical field
The utility model relates to Weight-measuring device, more particularly, relates to a kind of electronic scales.
Background technology
Electronic scales is a device of measuring testee weight with pressure transducer (or maglev type) as load-sensing unit.The principle of work of electronic scales is as follows: when testee is placed on the scale pan, because of the weight of object self has a pressure to pressure transducer, make pressure transducer generation deformation, thereby impedance is changed, driving voltage is changed, and export the simulating signal of a variation; Above-mentioned simulating signal outputs to analog to digital converter through the amplifying circuit amplification and converts the digital signal of being convenient to handle to, and outputs to the CPU s operation control; After the CPU computing result is outputed to display.
Characteristics such as electronic scales has digital intuitive display, accuracy height, resolution is strong, range of weighing is wide, maintenance is simple, volume is little, correction is simple are widely used in all trades and professions.Control, adjustment or correction etc. to electronic scales realize by the button that is arranged on the electronic scales body (or display).
Yet existing electronic scales all is structure as a whole, and promptly the function button of electronic scales is arranged on the electronic scales body.During function button on using the scale body, will inevitably touch the electronic scales body, and, therefore often use button might cause the electronic scales body not steady, its accuracy and stability are reduced because electronic scales when operate as normal, needs an environment stably.In addition, be arranged on the scale body button also may because alleged article have corrosivity, toughness etc. not only button very easily damage, but also can make the inside components and parts of electronic scales be vulnerable to damage, influence the result of use and the serviceable life of electronic scales.
The utility model content
The technical problems to be solved in the utility model is, at the above-mentioned electronic scales of the prior art normal bad and antiseptic property of the button defective that influences accuracy, stability and the serviceable life of electronic scales such as not good in use, provides a kind of new electronic scales.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of electronic scales, comprise the control device that is used to measure the scale body of testee weight and is used for the input operation instruction, described scale body is provided with control interface, and described control device is connected to described scale body by described control interface.
In electronic scales described in the utility model, described control device comprises the heavy button of button at least, button makes zero.
In electronic scales described in the utility model, described control device comprises correcting key.
In electronic scales described in the utility model, described control interface is the computer mouse interface, and described control device is a computer mouse.
In electronic scales described in the utility model, described control interface is PS/2 interface or USB interface.
In electronic scales described in the utility model, comprise pressure transducer, amplifier, AD converter, CPU (central processing unit) and display unit in the described scale body.
Electronic scales of the present utility model is controlled electronic scales by external control device, thereby need not to contact the scale body in control procedure, has avoided the reduction of the electronic scales performance that causes because of control operation; And, because of having selected anticorrosion and robust shell for use, protected the components and parts in the scale body better, correspondingly prolonged its serviceable life; In addition, after control device damages, be convenient for changing, and control device grants asylum with some modes easily.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model electronic scales embodiment;
Fig. 2 is the circuit diagram of the embodiment of scale body among Fig. 1.
Embodiment
As shown in Figure 1, in an embodiment of the present utility model, electronic scales comprises scale body 10 and control device 20.In the present embodiment, control device 20 is independent of scale body 10.
Above-mentioned pressure transducer can be resistance-type, condenser type, maglev type, hydraulic type etc.After testee was placed on the scale pan 13, a pressure was applied to pressure transducer, makes pressure transducer generation deformation, thereby impedance is changed, and driving voltage is changed, and exported the simulating signal of a variation; Above-mentioned simulating signal outputs to analog to digital converter through the amplifying circuit amplification and converts the digital signal of being convenient to handle to, and outputs to the CPU s operation control; After the CPU computing result is outputed to display, as shown in Figure 2.
Certainly, in concrete application, scale body 10 can adopt other any existing structure.
The display screen 11 that scale body 10 is provided with control interface 12 and shows measurement result.Control device 20 is connected to scale body 10 by control interface 12.Control device 20 is used for input operation and instructs scale body 10.Control device 20 can comprise the heavy button of button, button and/or correcting button etc. make zero.In the present embodiment, control interface 12 is the computer mouse interface, and control device 20 is a computer mouse, and control interface 12 can be PS/2 interface or USB interface.Because control device 20 is plugged into scale body 10 by control interface 12, and control device 20 employing general calculation machine mouses, therefore after control device 20 damages, can change easily.
Because control device 20 is independent of scale body 10, therefore electronic scales is detained heavy, need not to contact scale body 10 when operation such as making zero, avoided the electronic scales Effect on Performance that causes because of operation.
