Installation of watch and defence of a determined space

Abstract: The present installation comprises an observation and intervention device destined to be assembled in a space to be watched over. In a rotative container (1), controlled by an engine (7), are assembled on a support plate (12) mobile with respect to the container under the control of an engine (11), a videocamera (15), a laser sight device (14) and a mirror (13) for a laser ray of intervention (8). A checkpoint outside the space watched over receives the images collected by the videocamera and permits to sight a target in this space. The laser of (power) permits then to intervene against this target, the ray of this laser being reflected by the mirror (13) in the same direction of that of the sight of the device (14).

Description: The present invention concerns an installation of watch and defence of a determined space, as the inside of a room of a bank counter, of a post office, of an airplain cabin, or of an outside space as the entry zone of a building to be protected. The installations of this type proposed until now, are not satisfactory from the point of view of their efficacy, their cost and their possibilities of application. Document DE-A-3736744 discloses a watch and defence installation comprising a mobile videocamera (3) and intervention means (1) operating integrally with said videocamera (3), where the images collected by the videocamera (3) are transmitted to a checkpoint where an operator can observe the watched space and can control work of said installation. The aim of the present invention is to provide an installation of watch and defence of a given space which permits on the on hand, by means relatively cheap, to watch over this space in a permanent way and, on the other hand, to take action, if necessary, in an offensive way to neutralize the person(s) undesirable who was/were able to introduce themself(ves) in said space, from a checkpoint located at distance. For this purpose, the installation according to the invention as defined in claim 1, comprises al least an observation and intervention device destined to be assembled in said space and a checkpoint destined to be placed outside this space, said device comprising a container in which are arranged a videocamera, a laser sight device and also a mirror for a laser ray of intervention coming from a laser of suitable power assembled outside said container, said container being equipped with an entry opening and an exit opening for said laser ray, said mirror, the sight device and the videocamera being assembled on a mobile support with respect to the container, so that the sight disposal and the videocamera are oriented in the same direction of the exit direction of said laser ray of intervention and said support being coupled to a first transmission engine, the installation comprising also means for transmitting to said checkpoint the images collected by the videocamera, first means to control said first engine from the checkpoint, and means to fire the laser from this checkpoint. The container of the observation and intervention device can be assembled in a mobile way with respect to the support means and placed so that it can be dragged by a second transmission engine. In this case, the installation can include means to control the second transmission engine from said checkpoint. Said mirror can be coupled with a compensation gearmotor; controlled by means of calculation means acting in such a way to correct the inclination of the mirror with respect to said mobile support, the videocamera and the sight device being integral to this support. According to a preferred embodiment, the container of the observation and intervention device, is assembled in a rotative way with respect to said support means and the support on which are fixed the mirror of the laser ray of intervention, the sight device and the videocamera are rotary revolving around a perpendicular axis of rotation of the container. The present invention will be better understood in the light of the description of the following embodiment, given as an example and illustrated in the enclosed drawings in which Figure No. 1 is a schematic front view, of an observation and intervention device being part of the installation according to the invention and, Figure No. 2 is a lateral cross section view of a part of this device. The device represented in figures 1 and 2 comprises a container 1 which comprises, in the present example, a cylindrical part 1a and a spherical part 1b, and a sleeve 1c which permits the suspension of the container to a support device 2, for example, a sleeper fixed under the ceiling of a room to be watched over. A flange 3 is fixed on the circumference of the sleeve 1c and retains the internal ring of a roller bearing 4, the external ring of this bearing being supported by means of fixing hooks as 5, 6. A trasmission engine 7 of the container 1 and a laser of suitable power 8 are equally fixed on the support device 2. The engine 7 comprises an axis 9 on which is assembled a transmission disk 10 which drags the container 1 by friction on the sleeve 1c. A second transmission engine 11 as a step by step engine is assembled inside the container 1 and is settled in such a way to drag around its axis a support plate 12 on which are assembled a mirror 13, a laser sight device 14 and a videocamera 15. The mirror 13 is coupled with an assembled gearmotor 22 controlled by a microprocessor so that to correct the inclination of the mirror with respect to de videocamera and to the sight device 14 which are assembled fixedly way on the plate 12. The support plate 12 contains equally an electronic circuit 16 grouping in this case, the feeding and controlling circuits for the engine 11 and the laser of the sight device 14 and also the feeding and treatment ciruits of the signals of the videocamera 15 and the microprocessor for calculating the correction of the inclination of the mirror 13. The electric links outside the container 1 pass through a collecting device 17, 18 linked in this case to a checkpoint, which is not represented, to which is connected the laser 8; also the different control and feeding links are not represented. The ray emitted by the laser of suitable power 8 indicated by the broken line 20 is reflected by a mirror 19, assembled fixedly with respect to the support device 2, on the mobile mirror 13 which reflects it in its turn through an opening 21 of the container 1 towards a target sighted. The power of the offensive laser 8 which can be a laser of the type CO 2 is for example of 150 - 475 W, the energy of the outgoing ray being regulated in such a way to put a person out of action. The watch of the determinate space is carried out from the checkpoint by the videocamera 15 which produces on a monitor of the checkpoint an image of the zone observed. During the watch, the container (1) has been made rotate continually and the mobile support plate 12 is dragged by the engine 11 in a sense, then in the other, between two angolar limit positions so that to explore all the space to be watched over. In the case in which an intervention against an intruder in this watched space is necessary, the operator can control, from the checkpoint, the engines 7 and 11 so that to sight by the laser device 14 the precise place on which he can take action and then can emit the laser of suitable power 8 whose ray 20 reflected by the mirrors 19 and 13 acts in such a way to neutralize a person as a terrorist or armed bandit.
