1. A multi-channel radio frequency transceiving device, comprising: an optical module, a digital signal processing module, a radio frequency transceiving module, a downlink module and a microprocessing module; wherein
an input terminal of the optical module is configured to receive an optical signal corresponding to baseband data, and an output terminal of the optical module is connected to an input terminal of the digital signal processing module; an interactive terminal of the digital signal processing module is connected to an interactive terminal of the radio frequency transceiving module, and a plurality of output terminals of the radio frequency transceiving module are connected to a plurality of input terminals of the downlink module in one-to-one correspondence; output terminals of the microprocessing module are respectively connected to a control terminal of the optical module, a control terminal of the digital signal processing module and a plurality of control terminals of the downlink module in one-to-one correspondence;
the optical module is configured to convert the optical signal into an electric signal; the digital signal processing module is configured to obtain the baseband data and channel number information on the basis of the electric signal, and allocate and process the baseband data on the basis of the channel number information; the microprocessing module is configured to determine the number of working channels of the radio frequency transceiving module, the corresponding number of working channels of the downlink module and a downlink output power on the basis of the channel number information and the baseband data, and close the remaining channels in the downlink module; each working channel of the radio frequency transceiving module is configured to perform up-conversion on the received baseband data, and each working channel of the downlink module correspondingly processes and outputs the up-converted baseband data; and
the number of channels of the downlink module which are in a working state is adjustable according to different channel number information.
