SCXI-1324 Master Device Data Transmission Module

SCXI-1324 inverter controller system principle through the inverter system current and voltage through the voltage Hall sensor and current sampling circuit were detected, sent to the analog signal processing circuit for analog filtering and amplitude adjustment, the processed signal is sent to the DSP chip, through the 12-bit A/D converter module within the DSP chip, into digital signals, the DSP digital filtering of the signal to determine the output voltage and current of the single-phase half-bridge whether the over-voltage or overcurrent and to take the appropriate protective measures

The SCXI-1324 master device sends data to the GPRS module when the GPRS module sends the signal to the GPRS network, the master device must indicate the destination address of the data, only then the network in the figure above can select the route for data transmission, processing and transmission of this set of data. The network transmits this data to the destination GPRS module, which then transmits the data to the connected slave device. The difference between the two transmission methods is that the RS485 bus does not use the destination address during transmission, it is a broadcast transmission method.
