In the traditional anti-misoperation locking system

the electric locks are all unlocked through the key hole

thus causing the disadvantage of being technically unlocked. An intelligent non-contact unlocking system is proposed

in which the computer key supplies power to the intelligent lock through magnetic coupling power transmission technology

and interchanges instructions with intelligent lock through short distance wireless communication technology for controlling the internal mechanical structure of intelligent lock to realize non-contact unlocking. Meanwhile

the design method and testing process of the key technology of the wireless power supply are described. Testing results are basically identical with the results of theoretical analysis. The new design can meet the requirement on technical specifications of interlocking

thus eliminating the possibility of technical unlocking and improving the safety of electric power production.
