Collector
The collector is used in the centralized meter reading system, which mainly completes the data collection of the RS485 meter, and uses the low-voltage power line as the communication c♒hannel to upload the electricity consumption data in the power line carrier mode and provide it to the centralized meter reading system. The collector is divided into two parts: uplink protocol processing and downlink RS485 meter reading; uplink supports carrier and infrared interfaces according to DL/T645-1997 and DL/T645-2007 protocol communication; downlink reads DL according to 1200bps /T645-1997 protocol meter, read DL/T645-2007 protocol meter according to the default 2400bps, the baud rate of reading DL/T645-2007 protocol meter can be set; when receiving the broadcast timing command, two baud rates are used respectively Send it to the RS485 bus to calibrate the two protocol meters.
