Cantilever crane identification system and cantilever crane identification method

The invention discloses an arm support recognition system and method, and the system comprises a plurality of recognition devices which are sequentially disposed on a plurality of fly jibs of a multi-arm-support mechanical device, each recognition device corresponds to a fly jib, and the adjacent recognition devices communicate with each other. A target recognition device in the plurality of recognition devices communicates with the resolving device, and the plurality of recognition devices are configured to sequentially compile the compiled data of each recognition device through a preset compiled rule and send the target compiled data of the target recognition device to the resolving device; and the resolving device communicates with the target recognition device and is configured to receive the target encoding data and resolve the target encoding data through a preset resolving rule so as to obtain a boom recognition result. According to the method, the boom is recognized in a data encoding and resolving m
