Description

A kind of wireless electron scale circuit

Technical field

The present invention relates to technical field of electronic equipment, particularly relate to a kind of wireless electron scale circuit.

Background technology

Scale is one of article conventional in current family, and existing scale is generally pressure transducer shape Formula, needs reading registration of bowing after measurement, during bowing, centre of body weight can migrate, Cause measured value unstable, and the person of being not convenient to use uses.

And existing electronic product, such as mobile phone, flat board etc., the most suitable is universal, so, as What enables the registration of scale to be sent on portable type electronic product by the form being wirelessly transferred, and solves The certainly above-mentioned drawback during weighing, is those skilled in the art directions of needing conscientiously to study.

Summary of the invention

In view of this, the invention provides a kind of wireless electron scale circuit, solve prior art is deposited Problem, concrete scheme is as follows:

A kind of wireless electron scale circuit, including the sensor circuit being connected in turn, electronic scale A/D change-over circuit, Single-chip Controlling center, display circuit, it is characterised in that: in described Single-chip Controlling The heart is connected with wireless transceiver circuit, described sensor circuit, described electronic scale special A/D change-over circuit, institute State Single-chip Controlling center, described display circuit, described wireless transceiver circuit are connected with power supply input circuit.

Concrete, described power supply input circuit is also connected with anti-jamming circuit.

Further, after described sensor circuit senses pressure by pressure transducer, control described electricity The connection of source input circuit.

Preferably, the transmitter module operating frequency in described wireless transceiver circuit is 315M, running voltage 3-12V, employing sound table resonator SAW frequency stabilization.

Preferably, the receiver module running voltage in described wireless transceiver circuit is 5V, quiescent current 4MA.

Present invention have the advantage that 1, measure numerical value accurately, stably.2, convenient to operate.
