Description
Technical field
The utility model relates to a kind of electronic scales, relates 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 assemblies such as its inner analog to digital conversion modular converter and controller are vulnerable to extraneous, magnetic, interference such as water vapor, thereby the stability and the precision of influence valuation scale are affected, and reduce serviceable life.
Summary of the invention
The purpose of this utility model is to propose a kind of digital sensing electronic price computing scale, and it can effectively prevent parameter modification, moistureproof anti-electromagnetic interference (EMI), thereby overcomes deficiency of the prior art.
For achieving the above object, the utility model 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 be sealed together to be packaged in the elastic sensing element of 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 oscillatory type sensor or resistance strain type sensor, and described analog-to-digital conversion module 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 utility model, its analog-to-digital conversion module and controller adopt extra small packaged device respectively, pcb board adopts ultra-thin, make whole electron device accomplish to minimize, with the burning portmask of controller on pcb board, the burning port and the external world of controller isolate fully, the pcb board that is integrated with analog-to-digital conversion module and controller is placed on the elastic sensing element inside of sensor, adopting silica gel that whole pcb board is sealed in the elastic sensing element forms a whole, the external world can't rewrite the program of controller inside by the burning port 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 the utility model one preferred embodiment;
Fig. 2 is the principle of work block diagram of the utility model one preferred embodiment.
Embodiment
Below in conjunction with an accompanying drawing and a preferred embodiment the technical solution of the utility model 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 through the interface web joint, 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 are formed, 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 burning portmask of controller isolates the burning 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 the burning port; Also be provided with the interface that can be connected on this pcb board with extraneous parts.
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 this pcb board is sealed in elastic sensing element one side in the sensor by silica gel, 3 of the external cables that is connected with the pcb board interface extend to outside the sensor 1, are connected with the interface web joint.
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 an integral body (digital sensing module) with sensor, therefore, stoped parameter modification, avoided revising the cheating that parameter is brought analog-to-digital conversion module and controller; 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 a metal, it can mask the interference of external electromagnetic to 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 the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique is under the situation that does not break away from spirit and scope of the present utility model, do various conversion or modification, all belonged to category of the present utility model.
