Definitions

  • the present invention relates to a system for monitoring people on a site.
  • a main object of the invention is to solve this problem.
  • the central unit does not dialogue with the beacons. It exchanges information over the air with portable transmitters.
  • portable transmitters are equipped with two receivers, one for receiving the beacon code, the other for receiving radio information transmitted by the central unit.
  • the invention in turn provides a system for simplifying the architecture of the transmitters.
  • the system according to the invention is characterized in that it comprises a carrier current transmitter connected to the central unit and transmitting, to beacons on the site's electrical supply network, information that it transmits the central unit.
  • the surveillance system shown in FIG. 1 is for example implemented in a residence for the elderly. It comprises a central unit 1, as well as medallions 2 worn by the residents to be watched. Each medallion 2 emits radio frequency RF signals intended to be received by at least one reception unit 4, to which the central unit 1 is connected.
  • Each zone Z of the monitored site is equipped with at least one beacon 3 emitting coded infrared IR radiation intended to be received by the medallions 2.
  • the code transmitted to the medallions 2 notably includes a location code specific to each beacon 3.
  • the central unit 1 is connected to a unit 5 which is a carrier current transmitter, by which it communicates with the beacons 3.
  • This unit 5 transmits, on the site's electrical distribution network 7, coded frames conveyed by the currents carriers.
  • the reference 6 schematically illustrates the supply of the network 7 by the 220 V lines of the sector.
  • the central unit 1 comprises a microcomputer 10 which manages the information received and transmitted by the network, as well as a printer 11 connected to the microcomputer 10.
  • the beacons 3 are infrared transmitters plugged into sockets 9 in the sector. They permanently emit in the infrared a code defining the place Z in which they are installed. They include means for programming the location code before the system is put into operation. The same tag 3 can thus be adapted to different places of installation.
  • the infrared emission power is significant.
  • the signals are transmitted omnidirectionally and are received, either directly or indirectly by reflection on the walls and ceiling of the room, by any receiving medallion 2 located nearby.
  • the IR signals have the essential characteristic of being stopped by material obstacles, and in particular by the walls and ceilings of the premises in which they are emitted, so that they are necessarily located, unlike radiofrequency radiation, which they pass through walls and ceilings.
  • a beacon 3 can be a simple beacon emitting only its location code.
  • a tag 3 can also include means for the reception of information conveyed by sector 7 in the form of carrier currents and for the transmission of this information to medallions 2.
  • the information can be transmitted by the unit 5 generally to all the beacons 3.
  • the beacons 3 modify their emission codes so as to re-transmit the information received intended for the medallions 2 .
  • the tags 3 can also be individually addressable by the unit 5. They for this purpose include a decoder of the frame received from the sector.
  • the information received by a tag 3 can also control a mechanism, in room Z where the tag 3 is located, such as a lock opening.
  • the infrared information sent by the beacons 3 may contain a specific acknowledgment code intended for the central unit 1.
  • the medallions 2 each include a unit 20 for the transmission of coded radio frequency signal frames.
  • the transmission is controlled by pressing a button 21a or 21b or tearing off the holding strap 22.
  • the button 21a triggers an emergency call signal; key 21b triggers a service call signal.
  • Each medallion 2 also comprises a reception unit 23 and storage means 24 in which the identification of the resident and the last location code received from a beacon 3 are stored.
  • a medallion 2 can always emit a location code, even if it is outside the range of emission of the beacons 3.
  • the medallions 2 send back to the central unit 1 a signal which notably includes their own code as well as the message received from the beacons.
  • Certain transmitters can be specific.
  • the transmitter used by the surveillance intervention personnel may be a box 8 comprising a keyboard 8 a and display means 8 b allowing the surveillance personnel to interact with the central unit 1.
  • the box 8 also has the same functionality as the medallions 2.
  • the code generated by typing on the keyboard 8a is integrated into the general location and identification frame sent in radio frequency.
  • the sending of the radio frequency frame triggers for box 8 an internal delay during which the reception of the acknowledgment code (carried by an IR signal) triggers an audible signal on said housing 8.
  • the power supply is interrupted and the site memory is reset to zero.
  • the keyboard 8a in particular allows callers to be identified by specific codes transmitted to the central unit 1.
  • the central unit 1 can transmit to the box 8, via the beacons 3, messages displayed on the screen 8b.
  • the box 8 can also include mobility detectors ensuring the protection of isolated personnel, this box 8 emitting a particular code in the event of prolonged immobilization.
  • the number of reception units 4 depends on the importance and the topology of the place to be covered.
  • the reception units 4 merely retransmit the information they receive. They can therefore be easily moved or their numbers modified, depending on the progress of the installation.
  • the carrier current transmitter 5 is controlled by the central unit 1.
  • It can be of the general acknowledgment type, that is to say it transmits the information it receives to all of the beacons, these all receiving and retransmitting, by infrared emission, the code received in addition their own location code.
  • It can also be a coded transmitter, and send the information transmitted to it by the central unit. on certain specific tags only.
  • the installation can be envisaged in new construction or on occupied site.
  • the premises can be gradually equipped.
  • the tag type can then always be changed to meet specific requirements.
  • the tags 3 are simply plugged into sockets 9 of the rooms, apartments, common premises and passageways of the site.
  • the location codes of the beacons 3 are programmed thereon, when they are set up on the site.
  • the apartment code is issued.
  • beacons 3 identifying common rooms are installed near the entrances.
  • beacons 3 in the corridors, and in particular in those leading to the outside, allows in the event of a call to know the direction taken by the person before his call.
  • beacons being carried out without wiring, the protection of the external zones is possible.
  • Breakpoints, summer garden, gazebo, ... can be equipped as well as crossing points, paths, crossings, gates ...
  • the central unit 1 On reception of a call frame, the central unit 1 warns the operator of the place of call, the name of the caller and possibly prepares a file on this caller.
  • the service provider On site, the service provider, by typing a code on its box 8, simply acknowledges the call if everything is in order or requires the intervention of a specific person.
  • the worker is informed by an audible signal emitted by the beacons or by his box 8, that his message has been taken into account by the central unit 1.
  • the coding returned by the tags 3 on the housing 8 may correspond to a particular response from the central unit 1.
  • One solution consists in having display means such as a screen in the vicinity of a specific verification tag 3 on a common passageway (restaurant, television room, etc.). The reception of a frame in the source of this tag 3 is recognized by the central unit 1 as a test and returns on the screen a message addressed by name to the sending boarder signaling that everything is in order.
  • the central unit 1 updates an activity control file.
  • the latter is also updated by all receptions, alarms or services, received from all transmitters 2 and 8 on the site. Consultation of this file brings up the list of transmitters 2 and 8 which have not transmitted for a specified time, for example for 24 hours or 48 hours.
  • Some of the apartments in these residences can be fitted with coded 3 beacons. Following a call, the central unit 1 periodically triggers, until acknowledged by the operator, the audible signal from the beacon 3 to reassure the caller.
  • Putting a terminal on standby (medallion 2 or other transceiver) in a room equipped with dialog beacons allows calls and messages to be sent to this terminal.
  • Terminal 2 by the personnel of service allows, for example, ordering meals and direct retransmission. This transmission being carried out from the occupant's own room allows the central unit to compare the request with a possibly prescribed regime.
  • FIG. 2 shows an access control system according to the invention.
  • the same reference numbering increased by 100 has been used.
  • This access control system notably comprises a central unit 101 connected to a radio frequency reception unit 104 and to a carrier current transmission unit 105 by computer links 112 and 113.
  • Beacons 103 for emitting infrared coded radiation connected to sector 107, are arranged near the access points, which are represented schematically by a door P in FIG. 2.
  • the people on site are equipped with boxes 108 which receive the IR frames emitted by the beacons 103 and emit RF radiation intended to be received by the units 104.
  • beacons 103 near the access points which do not give rise to an intensive passage, offers an economical alternative to conventional systems using a smart card or magnetic strip.
  • coded beacons 103 and RF transmitters 108 with displays allows the establishment of a dialogue in complete confidentiality with the central unit 101.
  • the choice of the number and location of the 104 RF reception units depends on the configuration of the site.
  • the type of transmission unit 105 depends on the communication protocol between the personnel and the central unit 101 and therefore on the type of beacon 103 adopted.
  • the immediate installation without cable offers the possibility of establishing the monitoring of a temporary activity: construction site, exhibition, temporary storage ...
  • the route of the rondiers can be modified according to the use of the premises under surveillance.
  • the new route will simply be redefined by moving the beacons to a new outlet.
  • the plumber can be discreetly informed when calling a route modification.
