Abstract
The utility model provides an electronic scale, which comprises a scale body, a sensor, an A/D converting module connected with the sensor, and a controller connected with the A/D converting module. Press-keys and a display screen are arranged onto the body of the scale, which are connected with the controller respectively. The A/D converting module and the controller are integrated onto the same PCB board. The PCB board is hermetically arranged inside the sensor, and the external cable extends out of the sensor. The scale has functions of fraud-preventing, water-proofing, moisture preventing, anti-electromagnetic interference.
Description
Technical field
The utility model relates to electronic scales.
Background technology
The electronic scales of usefulness in the market comprises sensor, A/D modular converter, controller, power supply, display screen, the button of scale body, induction pressure.Its A/D modular converter separates with controller and is arranged in the scale body, opening the scale body case both can make amendment to the parameter of A/D modular converter and controller and reset, therefore the electronic scales that can practise fraud that has occurred much giving short weight on market has brought unnecessary loss to people in daily life.And, cause such electronic scales to be vulnerable to outside electromagnetic interference, and waterproof and dampproof performance is bad because its outside does not have other shieldings.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can be in case the electronic scales of parameter modification, waterproof and dampproof anti-electromagnetic interference (EMI).
In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is a kind of electronic scales, and it comprises the scale body, is arranged on the sensor of described scale body internal induction pressure, the A/D modular converter that is connected with described sensor, the controller that is connected with described A/D modular converter; Be arranged on button and display screen on the described scale body, described button and display screen are connected with described controller respectively; Described A/D modular converter and controller are integrated on the pcb board; Described pcb board is sealed to be positioned over described sensor internal, and its external cable extends outside the described sensor.
Described pcb board sealing is arranged in the elastic body of described sensor.
Electronic scales of the present utility model, its A/D modular converter 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 A/D modular converter and controller is placed on sensor elastomer inside, adopting silica gel that whole pcb board is sealed in the elastic body 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 A/D modular converter, play the effect of anti-cheating, also play waterproof and dampproof effect simultaneously.Because elastic body three faces all are metal materials, one side by the Copper Foil on pcb board top layer, plays the purpose of the anti-electromagnetic interference (EMI) of electronic scales in addition.

Embodiment
At electronic scales of the present utility model, now lift a preferred embodiment and be specifically described in conjunction with graphic, referring to Fig. 1, Fig. 2:
Electronic scales comprises scale body (not shown), in this scale body, be equipped with can senses change in pressure sensor 1, the elastic body 2 that this sensor 1 adopts is an aluminium alloy resistance formula sensor;
PCB printed circuit board (PCB) (not shown) adopts ultrathin pcb board, is integrated with A/D modular converter and controller on this pcb board, and this integrated approach does not repeat them here for existing integrated technique; This A/D modular converter and controller all adopt the subminiaturization device, can effectively reduce to install to take up room; A/D modular converter one end that is integrated on the pcb board is connected with sensor 1, and an end is connected with controller; The burning portmask that is integrated in the controller on the pcb board is on pcb board, the burning port and the external world are isolated fully, purpose is before production control program to be burnt into controller, when having arrived in user's hand, can the person of banning use of change controller parameter by the burning port; This pcb board is provided with the interface that is connected with extraneous parts such as sensor, display screen, button, power supplys; Its middle controller is connected respectively with display screen and button by display screen interface, keystroke interface, and the A/D modular converter is connected with sensor by sensor interface; The extraneous power supply of power interface is that parts integrated on the pcb board are powered;
This pcb board that is integrated with A/D modular converter and controller is installed in elastic body 2 one sides of sensor 1, and by silica gel this pcb board is sealed in elastic body one side in the sensor, and the external cable 3 that interface externally connects on it extends to outside the sensor 1;
This scale body is provided with display screen, button, its installation and structure can with reference on the existing market electronic scales; This display screen and button are connected with controller on the pcb board by cable respectively.
The electronic scales of this structure, it is because A/D modular converter and controller are integrated on the pcb board, and therefore this pcb board sealing is installed in the sensor,, stoped parameter modification, avoided revising the cheating that parameter is brought A/D modular converter 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 A/D modular converter and controller, play waterproof and dampproof purpose; Because the elastic body of sensor is a metal, it can mask the interference of external electromagnetic to A/D modular converter and controller in conjunction with the lip-deep Copper Foil of pcb board, has the function of anti-electromagnetic interference (EMI).
Claims (2)
1. electronic scales, it comprises the scale body, is arranged on the sensor of described scale body internal induction pressure, the A/D modular converter that is connected with described sensor, the controller that is connected with described A/D modular converter; Be arranged on button and display on the described scale body, described button and display are connected with described controller respectively; It is characterized in that described A/D modular converter and controller are integrated on the pcb board; Described pcb board is sealed to be positioned over described sensor internal, and its external cable extends outside the described sensor.
2. electronic scales according to claim 1 is characterized in that described pcb board sealing is arranged in the elastic body of described sensor.
