Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment further illustrates technical scheme.
As it is shown in figure 1, a kind of intelligent wireless ammeter, it mainly includes electric energy acquisition unit, signal processing unit, communication unit
Unit；Measuring part and give control unit by measurement data (electric current, voltage, power etc.), single-chip microcomputer was arranged according to the period, to nothing
Merit, meritorious, rate, electric current, voltage etc. calculate, and drive display device show for information about, by interface circuit with outward
Portion carries out data transmission and communicates.
As in figure 2 it is shown, Si4438 transceiver uses diversity antenna and high efficiency power amplifier, system link can be improved pre-
Calculate, extend transmission distance for intelligent electric meter, and reliable communication link is provided；On Si4438 transceiver sheet, integrated power amplifies
Device, low-noise amplifier and surface acoustic wave filter, reduce cost while improving performance so that it is under rugged environment also
Can effectively transmit；Integrated temperature sensor, GPIO and electrification reset circuit reduce further system cost, reduce circuit board
Size.
When data send, each module is provided with GPIO mouth, and single-chip microcomputer receives other data platforms by RS485 serial ports and sends out
The data sent here, then control ZigBee chip Si4438 and carry out DSSS, finally it is transmitted in the air by antenna；Receive number
According to time, the data that antenna is received by Si4438 inside de-spread after, single-chip microcomputer transfers data on other data platforms again.
