The invention discloses a conference discussion system of a dual-channel communication link and a working method, two channel main control units are arranged in each unit machine, namely, two independent audio channels are arranged in the unit machine, and independent audio acquisition and transmission can be carried out; meanwhile, two host channel main control units are arranged in the host and used for receiving audio data of two channels in the unit machines respectively, so that equivalently, an independent double-channel unit machine and a host signal acquisition channel are arranged in the system, and when one channel of audio has a fault, the two channels of audio can be transmitted to the host through the host channel main control units. Normal audio transmission of the conference discussion system can still be ensured, and the disaster redundancy capability of the system is enhanced; besides, an audio automatic selection unit is additionally arranged in the host, fault identification of two paths of
