ELEKTRONISCHES SICHERHEITSSYSTEM |
摘要 |
<p>An electronic security system includes an electronic lock mechanism and an electronic key, each of which is provided with a microprocessor controller and a memory storing data including an ID code. The lock microprocessor changes the ID code stored in its memory upon the operation of the lock by a correct key. The key can only be used to operate the lock once, and thereafter must be reprogrammed by a host computer with the updated ID code for the lock. The electronic lock operates a solenoid which retracts a bolt blocking mechanism which prevents the unlocking of the bolt even when a key having the correct mechanical key cuts is inserted into the lock. Power for operating the electronic lock as well as the solenoid is provided by a power supply within the key.</p> |
