Anti-mis-insertion system based on vehicle variable current control sub-circuit board

The present invention provides an anti-mis-insertion system based on the vehicle variable current control sub-circuit board. The anti-mis-insertion system comprises: a first sub-circuit board and a motherboard disposed on the chassis. The motherboard comprises a plurality of lines of slots arranged in parallel and a respective memory corresponding to each slot, and the memory is configured to store attribute information of a second sub-circuit board which is correctly inserted in the slot; each slot is provided with a plurality of interfaces, the plurality of interfaces arranged in each slot are arranged in the same order, and the interfaces of the same type located in different slots are arranged in the same line; and when the first sub-circuit board is inserted into the slot on the motherboard, the first sub-circuit board is configured to obtain the attribute information of the second sub-circuit board stored in the memory and determine whether the attribute information of the second sub-circuit board is th
