DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a system for surveillance of a mobile or movable object.
The surveillance of mobile or movable objects, such as works of art, for example, presents the difficult problem of maintaining maximum surveillance security while allowing normal accessibility to such objects for exhibition purposes.
At present, works of art are put under surveillance either by surveillance of the perimeter of the premises in which they are housed, using perimeter or volume protection systems such as intruder surveillance radars whenever the exhibition is interrupted or terminated, or by mechanical or electromechanical protection means of which the most reliable go as far as denying physical access, so that visitors to an exhibition are physically separated by means of a transparent partition that is considered to be unbreakable.
All too often, this gives rise to constraints or servitudes that go firstly against the appearance of the protected work of art such that the honest spectator is thwarted artistically, and secondly against the well-understood need for economy in the protection of the corresponding artistic heritage, since it is not possible for every work to benefit from such protection independently of its artistic and/or market value.
In contrast an object of the present invention is to provide a surveillance system for a mobile or movable object enabling maximum security to be provided for minimum servitude and applicable to any work of art or mobile or movable object subjected to the system.
Another object of the present invention is to provide a surveillance system for a mobile or movable object suitable for providing dedicated surveillance of one or more works of art or mobile or movable objects in a set of works of art or mobile or movable objects in a collection.
Finally, another object of the present invention is to implement a surveillance system for a mobile or movable object making it possible simultaneously to obtain a high degree of operating independence, very great flexibility in use, and maximum security in so far as the surveillance proper of one or more mobile or movable objects may be associated with surveillance or monitoring of the environment of said objects, at least in part.
According to the present invention, a system for surveillance of a mobile or movable object placed in a surveillance enclosure is remarkable in that it comprises a transmitter/receiver device for transmitting and receiving first and second object-monitoring signals, the first object-monitoring signal serving to monitor the presence of the object and the second object-monitoring signal serving to monitor the position of the object. A device for transmitting an alarm-triggering signal is provided, said device receiving the first and second object-monitoring signals and enabling an alarm-triggering signal to be transmitted conditionally on the basis of a logical and/or an analog combination of the first and second object-monitoring signals.
The system for surveillance of a mobile or movable object in accordance with the invention is applicable to the surveillance of art objects exposed in museums or in temporary exhibitions, and more generally to any objects of value or valuables placed within a perimeter that may optionally itself be protected.
A more detailed description of the system of the present invention is given below in the following description and with reference to the accompanying drawings, in which:
FIG. 1 is a general overall view of the system of the present invention for surveillance of a mobile or movable object;
FIG. 2a shows a detector specifically adapted to implementing the surveillance system of the present invention;
FIG. 2b is a block diagram of the electronic circuits suitable for use with a detector as shown in FIG. 2a;
FIG. 2c is a non-limiting example of an alarm-triggering relay element disposed in the surveillance enclosure;
FIG. 3a is a circuit diagram of a particular embodiment of a signal transmitter suitable for implementing the electronic circuits shown in FIG. 2b;
