Radio frequency reading device, node writing method thereof and radio frequency data processing method

The invention discloses a radio frequency reading device, a node writing method thereof and a radio frequency data processing method, and belongs to the technical field of archive automation management. Comprising a radio frequency data processing system and a multi-channel radio frequency reading system, the radio frequency data processing system comprises an upper computer and a plurality of radio frequency main control boards, and each radio frequency main control board comprises a main control board controller module. The main control board controller module is connected with a bus data input and output module, a key module, an address module and a main control board indicating circuit, and the bus data input and output module converts a communication signal output by the main control board controller module into a differential signal corresponding to an RS485 bus and a CAN bus; the address module is used for determining an RS485 bus node number address of the radio frequency main control board; and the m
