Binary algorithm combined positioning device for unloading trolley of steelmaking overhead bunker

The invention relates to a binary algorithm combined positioning device for an unloading trolley of a steelmaking overhead bunker, the positioning device is composed of a furnace position positioning system and a bunker position positioning system, the furnace position positioning system judges the number of converters in which the unloading trolley is located, and the bunker position positioning system judges the number of bins in which the unloading trolley is located; then the actual position of the unloading trolley can be judged according to the furnace position and the bin position where the unloading trolley is located, and a furnace position check block and a bin position check block are installed on the unloading trolley; and according to the technical scheme, a large amount of cable wiring is saved, the more the bins are, the higher the cable saving proportion is, the number of occupied PLC digital quantity input modules is greatly reduced, and the more the bins are, the higher the PLC resource savi
