Abstract

A security system, which is introduced into a vehicle or a building having one or more doors, includes a receiving circuit to receive a prescribed remote control signal, an unlocking control mechanism to make a locking mechanism or locking mechanisms to one or more doors be in the unlocked state when the prescribed remote control signal is received, a closing detecting mechanism to detect the closing of a door, and a locking control mechanism to make the unlocked locking mechanism or mechanisms be in the locked state, when the door that is opened after the door or doors are unlocked, and then the closing of the opened door is detected.

an opening detector operable to detect the opening of one of the one or more doors; and

a locking controller operable to make the unlocked locking mechanism or mechanisms be in the locked state, when the opening of the one of the one or more doors is detected by the opening detector after the one or more doors are unlocked by the unlocking controller with a capture of the emergency signal;

wherein the locking mechanism or mechanisms are self-locking mechanisms.

5. A security system, which is introduced into a vehicle or a building having at least two or more doors, comprising:

a receiver operable to receive a prescribed remote control signal and/or a capturing mechanism operable to capture an emergency signal;

an unlocking controller operable to make a locking mechanism to a prescribed door be in the unlocked state, when the receiver receives the prescribed remote control signal or the capturing mechanism captures the emergency signal;

a closing detector operable to detect the closing of the prescribed door; and

a locking controller operable to automatically make the locking mechanism to the prescribed door be in the locked state, when the prescribed door is opened after being unlocked by the unlocking controller with a capture of the emergency signal, and then the closing of the opened prescribed door is detected by the closing detector.

6. A security system, which is introduced into a vehicle or a building having at least two or more doors, comprising:

a receiver operable to receive a prescribed remote control signal and/or a capturing mechanism operable to capture an emergency signal;

an unlocking controller operable to make a locking mechanism to a prescribed door be in the unlocked state, when the receiver receives the prescribed remote control signal or the capturing mechanism captures the emergency signal;

an opening detector operable to detect the opening of the prescribed door; and

a locking controller operable to make the locking mechanism to the prescribed door be in the locked state, when the opening of the prescribed door is detected by the opening detector after the prescribed door is unlocked by the unlocking controller with a capture of the emergency signal;

wherein the locking mechanism to the prescribed door is a self-locking mechanism.

7. A security system, which is introduced into a vehicle or a building having at least two or more doors, comprising;

a receiver operable to receive a prescribed remote control signal and/or a capturing mechanism operable to capture an emergency signal;

an unlocking controller operable to make locking mechanisms to the at least two or more doors be in the unlocked state, when the receiver receives the prescribed remote control signal or the capturing mechanism captures the emergency signal;
