The invention relates to a non-national-standard-system type turnout drive system based on a double 2-vote-2 framework. The system comprises interlocking lower computers IPS, an interlocking maintenance console SDM and non-national-standard-system type turnout drive modules HIOM. The non-national-standard-system type turnout drive modules HIOM, full-electronic communication modules EIOCOM2 and theinterlocking lower computers IPS are sequentially connected. The full-electronic communication modules EIOCOM2 are connected with the interlocking maintenance console SDM. The two non-national-standard-system type turnout drive modules HIOM redundant to each other obtain turnout drive commands through the interlocking lower computers IPS, control drive relays in a non-national-standard-system type turnout to be attracted up and fall down, drive the turnout to rotate in the stipulated direction, acquire expression information of the turnout and judge the position of the turnout. Compared withthe prior art, the system has the beneficial effects of being high in reliability and maintainability and the like.
