FR2593306A1 - Monitoring device for mobile units - Google Patents

Abstract

The invention relates to a device making it possible automatically to monitor the entry and exit movements of mobile units (cars, lorries, motor cycles, boats, etc.) spending time within an enclosure equipped with barriers or otherwise, with identification of the user, and a facility for detecting anomalies on board the mobile unit. The invention consists of a fixed base installation, figure A, situated at a point of obligatory passage of the enclosure to be monitored and an independent box, figure B, situated inside the mobile unit. The device according to the invention is particularly intended for monitoring movements (entries and exits) of mobile units situated inside an enclosure to be guarded, with a view to prevention of abnormal traffic by the units, theft of them, to their safety or to prevention of the partial theft of elements located inside a mobile unit.

Description

 The present invention relates to a device intended to automatically control the movements of entry and exit of mobiles (cars, trucks, motorcycles, boats, ...) located inside an enclosure to be kept (airports, military bases, fleets of administrative or private vehicles, port facilities, protected sites, etc.) with or without barriers, with identification of the mobile user.

 By controlling the movements of entry and exit, the device according to the invention makes it possible to prevent any abnormal circulation of the mobile or any use thereof by an unauthorized person.

 The device according to the invention consists of two complementary elements comprising a basic installation associated with the enclosure to be monitored and an autonomous box located inside the mobile.

 The accompanying drawings illustrate the invention. Figures A and B show the complete device according to the invention.

 Figure A represents the basic installation which equips the monitored enclosure. The materials that compose it are called checkpoints.

 Figure B represents the autonomous case which will be installed on board the mobile.

The basic installation shown in Figure A includes
- a passage detector device (1) of the mobile which may, depending on the
need to be equipped with acoustic, magnetic, inductive sensors,
optical (infra-red, ultra-violet or laser), radio-electric or
video,
- an interrogator (2) operating according to the need in inductive mode,
optical (infra-red, ultra-violet or laser) or radio electric.

- a microcomputer (3) constituted by a processing unit (3.1),
a management and memory unit (3.2) and an identification unit (3.3).

- an alarm (4) which will signal any abnormal passage from a mobile to the tra
towards a compulsory crossing point of the monitored enclosure.

- a printer (5) makes it possible to have the trace of the passage of the mobiles
(entry or exit) with indication of the time of passage.

- a dialogue unit (6) makes it possible to control the entire installation
lation fixed and perform memory updates.

 The elements of (1) and (2) may be located near or at a distance from the other elements in Figure A.

The installation on board the mobile represented in FIG. B comprises
- an autonomous set which integrates the identifier functions (7) and
answering machine (8), operating as required in inductive mode,
optical (infrared, ultra-violet or laser) or radio-electric,
- anomaly sensors (9) can be connected to the answering machine (8)
for transmission of these to the fixed installation of FIG.

 The operation of the invention shown in Figures A and B includes the detection of the passage of the mobile by (1) which provides basic information to the processing unit (3.2). This controls the identification unit (3.3) which will cause (2) the interrogation of the mobile. On receipt of the interrogation signal, the equipment of figure B, installed on board the mobile will take from the identifier (7): keyboard or magnetic or optical reader, the specific information identifying the mobile (for example: the number registration code) and the secret code characterizing the user, known only to the user, to transmit them by (8) to the interrogator (2).

The secret code is communicated by the user to the identifier before passing through the detection system. This code is only kept in memory for the time necessary for identification,
The message received from the mobile is communicated to the microcomputer (3) which compares it to the elements stored in its memory. In the absence of the secret code, the presence of an erroneous code or the absence of a response from the mobile, an alarm is generated by (4), and a message is printed in (5). This message includes the trace of the passage of the mobile (incoming or outgoing), the identification of the mobile if this information appears in the message received, and the time of passage.

 The dialogue unit (6) makes it possible to update the memory of the microcomputer.

 A mode of operation called "Anomaly detection" is achieved by adding sensors (9), connected to the elements (7) and (8). In this configuration, each time one of the sensors registers an anomaly (for example: access to the interior of the mobile of an unauthorized person, waterway inside a boat, ... ), an alarm message will be transmitted to the control station by the answering machine (8).

 The reception of this alarm message by (2) will cause the alarm (4) to be triggered and the corresponding alarm message to be printed on (5).

 The device according to the invention is particularly intended for monitoring the movements of mobiles staying inside an enclosure, with a view to controlling their use or combating the theft of these mobiles.

 When using the "Anomaly Detection" mode, the device will transmit an alarm characterizing the type of anomaly to the control station, in order to prevent possible = claims or partial theft '' elements located on board the mobile (example: waterway on board a boat, or intrusion on board the mobile of an unauthorized person).
