The invention provides an intelligent, highly reliable dual power supply local fan integration control system and belongs to the coal mine local fan control technical field. A technical scheme of the invention is as follows: the dual power supply local fan integration control system comprises two sub-control circuits: a first sub-control circuit and a second sub-control circuit which have a same composition and are symmetrically arranged; composition of the first sub-control circuit is as follows: a lead-out end of an isolation commutation switch SW1 is respectively connected with an input terminal a transformer T3 and lead-in ends A1 and A2 of a first local fan control circuit; an lead-out end A3 of the first local fan control circuit connects a local fan motor D1; an lead-out end A4 of the first local fan control circuit connects a local fan motor D2; a communication terminal A5 of the first local fan control circuit connects a communication terminal A6 of a second local fan control circuit of the second sub-control circuit. The system in the invention is suitable for a coal mine field and the like.
