The present invention discloses a universal connection recognition system which includes a universal connector, a pin recognition module and a signal detection module, wherein the universal connector is composed of plural testing pins that are electrically connected to plural connection pads to be tested, while at least one testing pin is connected to each connection pad to be tested. With the implementation of the present invention, complex production process or equipment is not required thus enormously reduce the implementation cost the universal connection recognition system can be applied to connections of great diversity of inspection instruments or equipment to thus make more applications possible and with the learning capability of the universal connection recognition system, any inspection instrument or equipment once connected is memorized to have the capability of achieving automatic and exact pin compatibility when the inspection instrument or equipment is connected again.
