Claim:
1. A method for detecting, recognizing, and automatic disarming of an alarm control unit for monitoring a secure space comprising at least one access opening that is closed by a door, using an alarm system comprising, on the one hand, the alarm control unit that comprises a main central processing unit and a main communication module and is supplied by an autonomous main power source or by the grid; on the other hand, at least one autonomous detection and identification assembly that is connected operationally to the control unit and that is associated with the door or with one of the doors, the or each assembly comprising one or two secondary central processing units, a proximity transmitter/receiver capable of being activated or put on standby, at least one detection sensor able to detect an opening of the associated door and/or a passage through the latter, one or two secondary communication modules making possible the communication with the control unit and one or two secondary power sources making possible the power autonomy of the or of each assembly; and still on the other hand, at least one active wireless communication portable medium comprising a wireless communication chip, such as a Bluetooth chip preferably of low power, and a memory containing an identifier, the or each activated proximity transmitter/receiver being able to establish a wireless communication with the or each chip to make possible the identification of the portable medium and the recognition of its identifier by the control unit that is designed, depending on whether the identifier is recognized or not, automatically to be disarmed or to trigger an alarm procedure, the method, based on a configuration where the or each proximity transmitter/receiver is in the standby state and where the control unit is in the armed or disarmed state, for the or each door in question, comprising performing the following consecutive steps a/ and b/: a/ automatically detecting, using the detection sensor(s), an opening of the door and/or a passage through the the door, b/ following said detection, depending on the arming state, armed or disarmed, of the control unit: i/ controlling the activation of the proximity transmitter/receiver in question to put the proximity transmitter/receiver automatically in the activated state enabling it to communicate wirelessly with the portable medium in question over a predetermined time t ii/ in the presence of the portable medium or of one of the portable media in the radio frequency communication field of the activated proximity transmitter/receiver, establishing the corresponding wireless communication to make possible the identification of the portable medium in question, iii/ transmitting the identifier of the portable medium that is thus present to the control unit that, depending on the recognition status of the identifier, performs either, when it is valid, the procedure for disarming the system or, in the absence of a valid identifier, the alarm procedure, optionally after an entry timing delay, iv/ in the absence of a recognized portable medium, controlling, at the expiration of the predetermined time t v/ automatically keeping the proximity transmitter/receiver in the standby state by acting directly or indirectly on the proximity transmitter/receiver.
