abstract
This electronic combination lock could use 51 system monolithic integrated circuit software and hardware resources fully, has introduced the intellectualized analysis function, enhanced system's reliability and the security, moreover, electronic combination lock, if with the serial communication unified will become the guesthouse, the factory, the school and so on to need together to carry on the commodity which the global administration the architectural complex could not lack. Integration of machinery's electronic combination lock, its function surpasses the spring lock greatly, and the performance is stabler, is safer. Its characteristic, the secrecy is first good, next the code variables; Its three error code input protection; Its four power cut code; Its five many kinds of password unblanking way, the easy to operate, does not have the single to unlock, 23 person of many kinds of unblanking ways. As a result of own superiority, the electronic combination lock will receive more and more people's welcome, the use will be getting more and more widespread, simultaneously, also will be accepted by the society the approval, and will share half and half with the spring lock.
