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 channel 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.
