    DEVICE FOR DETECTING THE OUTPUT OF THE BED OF A PERSON
    The present invention relates to a device for detecting the exit of a person's bed. People with loss of autonomy tend to get up at night, to go to the bathroom for example, and to walk in the dark. In these circumstances, the risk of falls is significant.
    In a first variant, a carpet is positioned at the foot of the bed of people with loss of autonomy. If the person falls from his bed, the carpet cushions the fall. This device is not satisfactory because the carpet does not prevent the fall and it can be inadvertently moved which can make it totally inoperative if it is inadvertently placed under the bed for example. According to a second variant, a movement radar is fixed in height on a wall and transmits a signal as soon as a person moves in the room.
    This embodiment is not satisfactory because it is difficult to differentiate a simple movement of the person in his bed from a real exit from the bed (in both cases, the person moves) and / or to differentiate a fall of a return to the bed of a person (in both cases the person can become still).
    The present application aims to overcome the drawbacks of the prior art by providing a detection device that allows to simply and reliably detect the exit of the bed of a person. For this purpose, the subject of the invention is a device for detecting the exit of a bed of a person. This detection device comprises a detection module and at least one lighting system and is characterized in that the detection module comprises a brightness sensor, at least one directional detection sensor configured to detect the presence of a person in a sensor. a detection zone located between the floor and an upper plane of the bed and a control means configured to activate the lighting system when the directional detection sensor detects the presence of a person. The use of a directional detection sensor makes it possible to differentiate the exit of a person's bed from simple movements of the person on the bed.
    In a preferred configuration, the detection module is positioned under the bed, at the head of the bed. Thus, the detection module can not be moved inadvertently. In addition, with a single detection module, it is possible to monitor the entire perimeter of the bed. Advantageously, the detection module comprises at least two directional detection sensors offset in height. The first directional detection sensor is positioned near the ground to detect a presence of a person in a first detection zone located under the upper plane of the bed and the second directional sensor is positioned above the upper plane of the bed to detect a presence of a person in a second detection zone situated above the upper plane of the bed. The detection module is configured to transmit a first type of message when only the first directional detection sensor positioned near the ground detects the presence of a person and to transmit no message or a second type of message when the two sensors of Directional detection detects the presence of a person. This configuration makes it possible to differentiate a simple exit from the bed of a fall.
    Advantageously, regulation is provided to gradually increase the light intensity emitted by the lighting system at the time of its activation.
    According to another characteristic, the detection module comprises a communication system configured to communicate with a platform, said platform comprising at least one computer as well as software configured to list messages received from at least one detection module. timestamp and optionally carry out a return of at least one message. Other features and advantages will become apparent from the following description of the invention, a description given by way of example only, with reference to the appended drawings in which:

    In Figure 1, there is shown a part 10 comprising at least one bed 12 and at least one electrical outlet 14.
    According to a preferred embodiment, the detection device comprises a detection module 16, a power supply module 18 and at least one lighting system 20.
    According to a first variant, the detection module 16 is in the form of a housing 22 placed on the ground, under the bed 12, at the head of the bed 12. In this position, the detection module 16 can not to be inadvertently moved. The detection module 16 being positioned at the head of the bed 12, a single detection module 16 is sufficient to monitor the entire periphery of the bed 12.
    Preferably, the power supply module 18 is a housing 24 distinct from the housing 22 of the detection module 16. In this case, the two modules 16 and 18 are connected by a wire link 26. This solution makes it possible to ideally position the module of detection 16 regardless of the position of the electrical outlet 14. In a variant, the detection module 16 and the power supply module 18 are grouped together in a single housing.
    According to one embodiment, the power supply module 18 comprises a plug adapted to be connected to the electrical socket 14 positioned on a first face, at least one electrical outlet positioned on another face and a connection for connecting the wire link 26 According to one embodiment, the lighting system 20 is in the form of an elongated element which comprises a plurality of light-emitting diodes (LEDs) distributed along its length and a connection configured to connect in a removable manner without tools the lighting system 20 in bed 12.
    In one configuration, the bed 12 comprises a metal frame 28 with a horizontal spar. In this case, the connection comprises at least one magnet 30 for releasably connecting, without the need for tools, the lighting system 20 in bed 12. Of course, the invention is not limited to this mode embodiment for the lighting system 20 or the link.
    According to one embodiment, the detection module 16 and the lighting system 20 are separate and connected by a wired connection 32. Preferably, this wired connection 32 comprises a first section connected to the detection module 16, a second connected section. the lighting system 20 and a connector 34 for connecting the first and second sections. Advantageously, the detection device comprises a means for detecting a bad connection of the connector 34 as well as a means for generating an alert when the detection means determines that the connector 34 is not correctly connected and that, consequently, the lighting system 20 is not operational. The alert may be a light signal and / or an audible signal and / or a message.
    In a variant, the detection module 16 and the lighting system 20 are integrated in one and the same element.
    The detection module 16 comprises at least one directional detection sensor 36 configured to detect the presence of a person in a detection zone situated between the ground 38 and the upper plane 40 of the bed 12. Thus, this sensor 36 makes it possible to differentiate the movements of a person on the bed of a person's movements outside the bed 12.
    For the present invention, the upper plane 40 of the bed is a horizontal plane positioned approximately at or very slightly below the upper face of the bed mattress.
    According to a first variant visible in FIGS. 2 and 3, for example, the detection module 16 comprises a single directional detection sensor 36 positioned near the ground 38 to detect the presence of a person in a detection zone situated under the plane upper 40 of the bed. According to this first variant, the directional detection module 16 may comprise two sensors positioned near the ground, oriented in two different directions. According to a second variant visible in FIGS. 6A to 6C, the detection module 16 comprises two directional detection sensors 36 and 36 ', a first directional detection sensor 36 positioned near the ground 38 to detect the presence of a person in a first detection zone 42 located under the upper plane 40 of the bed and a second directional sensor 36 'positioned above the upper plane 40 of the bed to detect the presence of a person in a second detection zone 42' situated above the upper plane 40 of the bed. According to this second variant, the detection module 16 comprises at least two directional detection sensors offset in height.
    This second variant makes it possible to differentiate the falls from a simple displacement in the room 10. In fact, in the event of a fall, only the first sensor 36 detects the person. In contrast, when a person moves in the room, the two sensors 36 and 36 'detect the person.
    Whatever the variant, the directional detection sensor 36 positioned near the ground 38 is positioned under the bed 12. Consequently, it can not detect the movements of the person on the bed and only detects the movements of the bed.
    According to one embodiment, each directional detection sensor 36, 36 'is a passive passive infrared sensor (PIR) configured to detect the presence of a person only in a detection zone delimited by two horizontal planes. As a guide, a sensor can cover an angular sector of 90 ° to 110 ° in a horizontal plane and an angular sector of 80 ° in a vertical plane.
    Of course, the invention is not limited to this type of sensor.
    According to another characteristic, the detection module 16 comprises a brightness sensor 44.
    According to an embodiment visible in FIG. 2, the detection module 16 comprises a first command 46 for activating or not a message sending mode and / or a second command 48 for activating or not a pilot mode and / or a third command 50 to set a timer.
    According to another characteristic, the detection module 16 comprises a control means, such as an electronics for example, configured to manage the activation or not of the lighting system 20, to adjust the intensity of the lighting, to manage the lighting. sending or not one or more messages and a communication system 52 configured to communicate with a platform 54.
    When several detection devices communicate with the same platform 54, each detection device comprises an identifier of its own. The identifier of the detection device 16 transmitting the message is incorporated in the message to enable the platform 54 to identify the detection device 16 having sent the message.
    The platform 54 comprises at least one computer as well as software configured to list the messages received from at least one detection module 16, to time-stamp them, to send back at least one message to a telephone of a person in question. function of the parameterization.
    Alternatively, the detection devices can transmit messages to an alert system generally provided in residential care facilities for dependent elderly people.
    According to another variant, the detection module comprises an input for connecting a command operable by the bedridden person, such as for example a sick call command.
    The detection device described above is versatile and can operate in different modes of operation.
    When the brightness detected by the brightness sensor 44 is greater than a given threshold, the detection device 16 is in the passive state. Consequently, the detection of a movement by the directional detection sensor (s) 36 does not cause the activation of the lighting system 20 and / or the sending of a message.
    When the brightness detected by the brightness sensor 44 is below the given threshold, the detection device 16 is in the active state.
    If the pilot mode is not activated, when the directional detection sensor (s) 36 detect (s) no movement, the lighting system 20 does not emit light, as illustrated in FIG. Figure 4A. Once a directional detection sensor 36 detects a movement, the detection module 16 controls the activation of the lighting system 20 which then emits a light as shown in Figure 4B. Preferably, the detection device comprises a regulation configured to gradually increase the light intensity emitted by the lighting system 20 at the time of its activation.
    If the pilot mode is activated by the command 48, the lighting system 20 operates as soon as the detection device 16 is in the active state. In the absence of movement, the lighting system 20 emits a light with a low intensity which corresponds for example to 5% of its maximum value, as illustrated in FIG. 5A. Once a directional detection sensor 36 detects movement, the detection module 16 controls the activation of the lighting system 20 which then emits a light as shown in Figure 5B. As previously indicated, the regulation makes it possible to gradually increase the luminous intensity emitted by the lighting system 20 at the moment of its activation.
    Independently of the pilot mode, when the lighting system 20 has been activated, it remains activated as long as a movement is detected by the directional detection sensor (s) 36.
    When no motion is detected for a given duration, the detection module 16 controls the deactivation of the lighting system 20 which turns off when the pilot mode is not activated or returns to a low intensity of illumination when the night mode is activated.
    The given duration can be regulated by command 50.
    When the message sending mode is activated by the command 46, the detection module 16 transmits a message each activation of the lighting system 20. This message is transmitted to a platform 54 which carries out a traceability of the activations of the control systems. lighting 20 of the different detection devices. Depending on the parameterization, the platform 54 can perform call forwarding to a telephone of a supervisor or to a monitoring station. On receipt of a message, the supervisor knows that a person has left the bed and can then decide what to do. In the presence of several detection devices connected to the same platform 54, the message sent to the supervisor or monitoring station includes an identifier to identify the person who has left the bed.
    When the detection module 16 comprises several sensors offset in height, the detection module 16 can differentiate the messages transmitted according to the detection of a movement by the two sensors or only by that positioned at the bottom.
    Thus, the detection module 16 transmits a first type of message when only the first directional detection sensor 36 positioned near the ground detects the presence of a person. The same detection module 16 transmits no message or transmits a second type of message when the two directional detection sensors 36 and 36 'detect the presence of a person.
