The computer scale is characterized in that the analog-to-digital conversion module and the controller are hermetically sealed in the elastic sensitive element of the sensor. The digital sensing electronic price computing scale in the invention can effectively protect from parameter modification, moisture and electromagnetic interference and has a simple and compact structure, stable capability, high precision and a long service lifetime.
Description
Technical field
The present invention relates to a kind of electronic scales, relate in particular to a kind of digital sensing electronic price computing scale.
Background technology
The electronic price computing scale of usefulness generally includes the scale body in the market, the sensor of induction pressure, analog-to-digital conversion module, controller, power supply, display screen and keyboard etc., wherein, analog-to-digital conversion module and controller split are arranged in the scale body, opening the scale body case can make amendment or reset the parameter of analog-to-digital conversion module and controller, reach the purpose of cheating, so just cause having occurred on the market electronic price computing scale of much giving short weight, brought unnecessary loss to people in daily life, and because this scale external body does not have other shieldings, cause such electronic price computing scale, especially the assemblies such as its inner analog to digital conversion modular converter and controller are vulnerable to extraneous electricity, magnetic, the interference such as water vapor, thereby the stability and the precision that affect balance are affected, and reduce serviceable life.
Summary of the invention
The object of the invention is to propose a kind of digital sensing electronic price computing scale, it can effectively prevent parameter modification, moistureproof anti-electromagnetic interference (EMI), thereby overcomes deficiency of the prior art.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of digital sensing electronic price computing scale comprises scale body, digital sensing module, keyboard, display; Described digital sensing module is arranged in the scale body, and described keyboard and display are arranged on the scale body; Described digital sensing module comprises sensor, analog-to-digital conversion module and the controller with elastic sensing element; It is characterized in that described analog-to-digital conversion module and controller are together in the sealed elastic sensing element that is packaged in sensor.
Preferably, described electronic price computing scale also comprises the interface card extender that is arranged in the scale body, and described interface card extender is connected with digital sensing module, keyboard, display and power supply respectively.
Preferably, described power supply is to be arranged at the built-in power in the scale body and/or to be arranged at the external external power supply of scale.
Preferably, described controller is one.
Preferably, described controller and analog-to-digital conversion module are integrated to be arranged on the pcb board, and described pcb board is sealed to be encapsulated in the elastic sensing element of sensor.
Preferably, described sensor adopts Vibratory transducer or resistance strain type sensor, and described modulus turns
Die change piece and control module be sealed to be arranged in the elastic body of this resistance strain type sensor.
More preferably, described sensor adopts aluminium alloy resistance strain gauge transducer.
Digital sensing electronic price computing scale of the present invention, its analog-to-digital conversion module and controller adopt respectively the device of extra small encapsulation, pcb board adopts ultra-thin, make whole electron device accomplish to minimize, the programming port of controller is shielded on pcb board, programming port and the external world of controller isolate fully, the elastic sensing element that the pcb board that is integrated with analog-to-digital conversion module and controller is placed on sensor is inner, adopting silica gel that whole pcb board is sealed in the elastic sensing element forms a whole, the program of controller inside can't be rewritten by programming port by the external world like this, also can't revise the parameter of analog-to-digital conversion module, play the effect of anti-cheating, also played waterproof and dampproof effect simultaneously.Because elastic sensing element three faces all are metal materials, one side plays the purpose of the anti-electromagnetic interference (EMI) of electronic scales by the Copper Foil on pcb board top layer in addition.
Description of drawings:
Fig. 1 is the structural representation of sensor in a preferred embodiment of the present invention;
Fig. 2 is the principle of work block diagram of a preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing and a preferred embodiment technical scheme of the present invention is done progressive explanation.
See also Fig. 1 and Fig. 2, this digital sensing electronic price computing scale comprises scale body (not shown), digital sensing module and interface card extender are installed in this scale body, the scale body is provided with display screen and keyboard, digital sensing module, display screen and keyboard are connected interface connecting plate and connect, and also are connected with power supply.
Aforementioned digital sensing module is by having sensor 1 elastic sensing element, can senses change in pressure, analog-to-digital conversion module, controller 2 and external cable 3 form, this sensor 1 preferred aluminium alloy resistance strain gauge transducer that adopts, analog-to-digital conversion module and controller 2 can adopt the subminiaturization device, take up room thereby effectively reduce to install.This analog-to-digital conversion module and controller can be integrated on the ultrathin pcb board, and analog-to-digital conversion module one end is connected with sensor 1, and an end is connected with controller; The programming port shielding of controller isolates programming port and the external world on pcb board fully, and purpose is before production control program to be burnt into controller, when having arrived in user's hand, can avoid the user to change controller parameter by programming port; Also be provided with the interface that can be connected with extraneous parts on this pcb board.
This pcb board 2 that is integrated with analog-to-digital conversion module and controller is installed in elastic sensing element one side of sensor 1, and by silica gel this pcb board is sealed in elastic sensing element one side in the sensor, 3 of the external cables that is connected with the pcb board interface extend to outside the sensor 1, are connected with interface connecting plate.
Aforementioned power source can adopt and be arranged at the built-in power in the scale body or be arranged at the external external power supply of scale, and certainly, but also both have concurrently.
The electronic price computing scale of this structure, itself since analog-to-digital conversion module and controller be integrated on the pcb board, and this pcb board sealing is installed in the sensor, form a whole with sensor (digital sensing module), therefore, stop the parameter modification to analog-to-digital conversion module and controller, avoided revising the cheating that parameter is brought; And because it is sealed in the sensor, can prevent that the aqueous vapor that enters the scale body from bringing infringement to analog-to-digital conversion module and controller, play waterproof and dampproof purpose; Because the elastic sensing element of sensor is metal, it can mask external electromagnetic to the interference of analog-to-digital conversion module and controller in conjunction with the lip-deep Copper Foil of pcb board, has the function of anti-electromagnetic interference (EMI).
Above preferred embodiment is only for explanation the present invention, but not limitation of the present invention, person skilled in the relevant technique in the situation that does not break away from the spirit and scope of the present invention, has been done various conversion or modification, all belong to category of the present invention.
