Description

TERMINAL FOR CENTRALIZATION DETECTION AND TRANSMISSION OF INFORMATION RELATING TO TECHNICAL RISKS INCURRED ON A SITE

The present invention relates to a security terminal for detecting, centralizing, and transmitting to a remote server the various data in connection with security alarms in service on a site.

It is well known that the technical supervision of construction sites, both in particular in the building sector and in that of the mechanical industries, is ensured by various devices which are for certain imposed by specific safety standards. Some of these devices are intended for the detection of an immediate risk and others are intended for the signaling of events implicating a deficiency in the security instruments precisely intended to combat such risks.

There are thus means capable of detecting the start of fires, which in particular consist of smoke detectors, and means intended to fight these fires once they have started, and which in particular consist of extinguishers of different types. There are also means for detecting and signaling gaseous fumes which are made up of specific sensors.

In addition to the fact that these various security means are in a dispersed state on the surface of the same site, there is no coordination between them nor any means allowing to control at any time and automatically and safely their good operational state.

The present invention aims to remedy these drawbacks by proposing a security terminal with which are linked different means for detecting dangerous events such as in particular fires, pollution by gases or floods, etc. as means capable of fighting against these dangerous events, all of these different means being coordinated and their management centralized so that they are effective immediately and at all times. In addition, the present invention proposes means making it possible to ensure the good operating condition of the equipment used to combat the dangerous events detected.

The present invention thus relates to a terminal for monitoring and managing dangerous events able to occur at a place to be controlled, of the type comprising at least one element for detecting a dangerous event and at least one device capable of fighting against the propagation thereof, characterized in that said detection element and said device are in connection with centralized management means able to connect to a remote server.

According to the invention, the device capable of combating the propagation of a dangerous event is associated with a presence sensor in connection with centralized management means. The latter may include a microcontroller or a microprocessor.

The terminal according to the invention may include at least one emergency device capable of fighting against the consequences of said dangerous event, this emergency device may in particular consist of a defibrillator or a medical kit.

The element for detecting a dangerous event may in particular include, for example, a gas detector, or a smoke detector. It may be arranged at the top of an arm, in particular of the telescopic type.

The terminal may include at least one manual tripping device in conjunction with the management automaton. It may also include an alarm device, in particular of the siren type, the triggering of which may be controlled by the management machine under the action, for example, of the manual triggering device.

This alarm device can be variable sound modulation according to the type of dangerous event detected.

The terminal according to the invention may include an element for detecting a dangerous event which will be associated with an alarm device in a housing of the autonomous power supply type, this sub-assembly being in relation to the management automaton by a link. remotely, in particular of the “Bluetooth” type.

Finally, the terminal may include a multimedia screen supplied by internal broadcasting means and / or by an internet link, as well as one or more cameras linked, in particular remotely, with the centralized management means.

An embodiment of the present invention will be described below, by way of non-limiting example, with reference to the appended drawing in which:

- Figure 4b is a schematic view of the implementation mode of a detector and removable siren assembly shown in Figure 4a, after its uncoupling from its support arm.

FIGS. 1 and 2 show an example of the implementation of a security terminal 1 according to the invention which is arranged, for example, on a site, on a place of temporary exhibition or outdoor event, etc. .. which we want to ensure security.

This terminal 1 comprises a box 3 whose base is intended to rest on the ground 5 and which is intended to receive various devices usually used to ensure safety on construction sites. Thus, this housing comprises, on either side of its front face, two supports 7a and 7b intended to receive fire extinguishers 9a and 9b and its lower part comprises a first housing 11 intended to receive a defibrillator 13, a second housing 15 intended to receive a first aid medical kit 17 and a third housing 19 intended to receive a survival blanket 21.

The base of the supports 7a and 7b comprises presence sensors, respectively 23a and 23b, with which the extinguishers 9a and 9b are thus associated. These presence sensors pass from a rest position to an active position when the extinguishers are removed from their support. These presence sensors are linked to a management automaton 25 as shown in the

figure 2 , that is to say that they are related to this one by a wired link or a binding to distance. Likewise, the base of housing 11, 15 and 19 has sensors of presence respective lia , 15a, and 19a which are also in

connection with the management PLC 25.

The housing 3 also includes on its front face two manual triggers, namely a fire warning trigger 27 and a medical trigger 29 which are also in connection with the management machine 25, as well as a multimedia screen 31 also in connection with the latter. This multimedia screen can be supplied via a multimedia module 32 either by an internal source capable of broadcasting, for example, the mode of use of the terminal or by an external source, in particular via an internet link.

A telescopic arm 33, in particular removable, disposed

on one sides of box 3 support at the once a detector smoke 37 and a mermaid 35. The front side of box 3 behaves also a platinum intercom 38 who is connected at a module

Intercom 40 of the management PLC 25.

The structure of the latter which schematically controls and operates all of these different elements is shown diagrammatically in FIG. 2.

This management controller 25 includes a mains supply 39 which supplies energy, through a buffer battery 41, to the various components of the terminal. Optionally, a second level of backup can be provided by means of batteries which will ensure the continuity of operation of the terminal at least as regards its essential functions.

The operation of the automaton is managed by a microcontroller 43 which includes a set of inputs / outputs which are connected to the various presence detectors and sensors used by the safety terminal 1.

The management automaton 25 comprises a power module 45 which is controlled by an output 46 of the microcontroller 43 and which supplies the siren 35. It also includes an internet communication module 48, for example of the 4G type, which makes it possible to ensure a link from the security terminal 1 according to the invention to a remote server 49, via the internet network. Regarding communication, the intercom module 40, under the control of the microcontroller 43 manages the operation of the intercom board 38.

As shown in FIG. 2, a large number of presence sensors and detectors can be connected to the various inputs / outputs of the microcontroller 43. Some of these detectors have been shown, by way of example and in a non-exhaustive manner. but it is quite obvious that one could, according to the needs, in other words according to the nature of the building site or the zone of the building site in which the security terminal 1 is established, to modify the nature as well as the number of these detectors. Thus, in addition to the presence sensors previously mentioned, namely the sensors 23a and 23b of the fire extinguishers, the sensor 11a of the defibrillator, the sensor 15a of the medical kit, the sensor 19a of the cover, as well as the manual triggers 27 and 29, a smoke detector 42 can be connected to the microcontroller 43, and specific gas detectors sensitive for example to carbon monoxide 44, methane 50, nitrogen monoxide 52, or ammonia 55.

Thus, for example, if the security terminal 1 is placed in an area where there is a fear of a critical release of methane or ammonia, the methane detector 50 and the methane detector will be connected to the inputs / outputs 54 and 56 respectively of the microcontroller 43. ammonia detector 55.

The detectors used according to the invention may be of the wired type or be detectors supplied autonomously, such as the carbon monoxide detector 44 in FIG. 2 and communicating remotely with the microcontroller 43 by a remote link, for example from the type called "Bluetooth" via a communication module 61 of the same type.

In an alternative embodiment of the invention and as shown in FIGS. 4a and 4b, a smoke detector 37a and a siren 35a which is associated therewith may be arranged in a housing 32 which will be removably mounted relative to the arm 33. In addition, a locating flash 36 will be placed on the housing 32. In order to ensure the maintenance of this housing, once the latter is separated from the arm 33, as shown in FIG. 4b, the latter will be able to this effect be provided with gripping means constituted for example by a hook 34 making it possible to fix it on an external element 30.

This arrangement will allow on the one hand to have the assembly consisting of the detector and the siren at a distance from the terminal 1 and on the other hand to associate with the same terminal several detectors judiciously distributed in the space to be monitored. Of course, for this purpose, the detectors will be of the autonomous type and will be provided with means for transmitting information remotely to the management automaton 25.

The terminal according to the invention can also be used as a device for monitoring intruders by using one or more volumetric detectors 57 as well as one or more cameras in conjunction with the management automaton 25.

An example of the operation of the safety terminal 1 according to the invention will be described below, illustrated by the diagram in FIG. 3.

When the terminal is started up, the management automaton 25, via its microcontroller 43, successively checks the state of each of the presence detectors and sensors in a loop.

When the microcontroller 43 detects a detector or a presence sensor which is in the active state, that is to say which is in a detection position, it checks whether it is indeed a detector which requires an immediate general alert. This is particularly the case of a smoke detector, a flood detector, a gas detector or the manual fire 27 or medical fire detector 29. The microcontroller 43 then triggers the siren 35 and starts communication with the remote server 49 via its internet communication module 48. According to the invention, the siren tone may be different depending on whether it is a fire, or a medical alert.

On reception, a security team manages in real time the information received by the server 49 relating to the dangerous event reported and contacts the service able to intervene, for example the guardian of the site on which the site, firefighters if it is a fire or gas service if it is a gas leak. The remote server then automatically sends a confirmation email to the authorized person and notes the incident in a follow-up file which will appear in a periodic report sent to the site manager in charge.

When the microcontroller 43 detects the activation of a presence detection sensor, such as the sensors 23a 23b, 11a, 15a or 19a, it does not then trigger the siren 35 but communicates with the remote server 49 which takes note of the nature of the element missing in the terminal and calls the responsible service to report it to him with the sending of a confirmation email and the mention of the incident in the follow-up file appearing in the previously mentioned periodic report.

Of course, it is possible to have, inside the same site, several security bollards according to the invention, which can communicate with each other in particular by a remote link, for example of the "Bluetooth" type.

The present invention is particularly advantageous in that it makes it possible to centralize the various information received in real time, not only at a terminal, but also at the level of all the security terminals which are distributed over the surface of the '' the same place to be monitored, thereby enabling surveillance personnel to acquire an overview, in particular of the extent and scale of an incident which has just occurred, such as for example a fire, a gas pollution etc ...

Furthermore, the present invention is also advantageous in that it makes it possible to permanently control the proper maintenance of the intervention equipment and to immediately remedy a failure thereof.

Finally, it allows rapid and almost immediate intervention to be implemented following the triggering of a signal relating to a dangerous event.
