KR950006183A - Ultra-Low Power Electronic Lock Driven by Key with Memory IC - Google Patents

Abstract

In the present invention, when a memory IC is embedded in a plastic package instead of a mechanical key and a circuit driving connection pin is exposed to the outside and inserted into a cylinder, the password stored in the IC is compared with the number stored in the controller of the electronic lock. The present invention relates to an ultra-low power electronic lock composed of a memory IC key and a cylinder designed to open and close a door.

In the conventional case, the lock can open and close the door with a mechanical key. In this case, the door can be opened and closed only by inserting the key into the cylinder and giving the rotation.

In addition, there is a problem that the risk of theft due to the copying and universal key of the key is high due to the mechanical key, and the number of types in the form of the same key is limited, and the structure of the key is inconvenient to carry on the body.

Therefore, the present invention can be unlocked by operating the solenoid only when the password is matched using only the memory IC key, so that the production of a limited number and the damage of theft due to the copy and universal key, which is a problem of the existing mechanical keys The purpose of the present invention is not only to solve the redundancy of the generated key but also to reduce the size of the key.

Claims (3)

An electronic lock which inserts a memory IC key and makes the door open when it is matched with a password stored in the memory at the receiving side of the electronic lock, wherein the control of the electronic lock when the password is stored and inserted into the cylinder The signal lines of the memory IC key 20 and the memory IC key 20 are interconnected with a function of receiving a power supply from the power supply 20 and transmitting a password and supplying an external device when the electronic lock is depleted. And the cylinder 40 for displaying the operation state, the power supply unit 50 for supplying power to the control unit and the memory IC key, the low voltage detection unit 60 for detecting the low voltage and informing the battery replacement time, the password and control unit of the memory IC key. If the password stored in the memory IC is characterized in that the door is opened by driving the solenoid Stored-type ultra-low-powered electronic lock key. 2. The battery circuit of claim 1, wherein only when the memory IC key 30 is inserted into the cylinder 40, the ground line D loops to operate the transistor Q1 through the resistor R6 so that the battery voltage is applied to the circuit. An ultra-low-power electronic lock driven by a key with a memory IC, which is characterized by a power supply unit 70 which is applied to prevent battery consumption. The key with a built-in memory IC according to claim 1, wherein when a battery of the electronic lock is consumed, power is supplied to the control unit 20 through the memory IC key 30 so as to operate normally. Power-saving ultra-low power electronic lock. ※ Note: The disclosure is based on the initial application.
