Definitions

  • the present invention relates to a bi-functional presence sensor, a system and a management method using such sensors.
  • the invention applies more particularly to the field of home automation and the tertiary field.
  • Home automation refers to all the techniques used by users in their homes and non-residential premises. These techniques can be automatisms or information systems intra or extra-localization.
  • Such automations can be based on the use of various sensors, distributed in the premises, measuring physical or physicochemical characteristics, and actuating, with respect to setpoints, heating, lighting, security and / or lighting equipment. or other domestic equipment.
  • Occupants of residential or non-residential premises can be brought, in fact, because of the repetitiveness of their activities, to realize the programming of equipment contributing to the creation of moods and security. Such programming is often difficult to achieve.
  • the development of electronics and computer technology makes it possible to propose solutions based on a prediction of the states of this equipment, which firstly involves the forecasting of the periods of occupation of these premises.
  • a known art document the request for patent FR 0 883 050 , describes a self-configurable manager who alone learns the thermal characteristics of a building, the presence and comfort needs of its occupants and their hours of occupation.
  • This energy manager comprises control means of a room conditioning generator for controlling the amount of energy that the generator must supply to reach a predetermined temperature.
  • the most commonly used presence sensors are piezoelectric sensors. Such sensors can cover a secure space more important than infrared barriers and are more generic than contact detectors placed in doors and windows.
  • Such sensors have the disadvantage of being only motion sensors. The amplitude of the detection signal depends of course on the energy emitted by a moving body but also on its movement speed. Thus, an immobile target is not detected. This is an important disadvantage both in the management of comfort when the sitting or lying occupants remain motionless as in the safe management when an intruder moves very slowly.
  • the invention therefore aims to achieve a combination of the two services that are comfort and safety, and solve the above problems by means of a single sensor.
  • the U.S. Patent 5,283,551 discloses a passive intrusion alarm system comprising an infrared sensor array, a sampling sensor that is in communication with a microprocessor through an analog-to-digital converter. The sensors are sampled to provide a two-dimensional thermographic image of an intruder.
  • the US Patent 5,969,608 discloses an intrusion detector which comprises a set of sensor modules arranged along a perimeter, which make it possible to detect seismic vibrations caused by an intrusion into the zone defined by this perimeter.
  • the request for EP 0 345 878 discloses a thermal radiation detection device which comprises an array of pyroelectric detectors for receiving radiation from a scene and for generate a voltage signal at its output which varies according to these radiations.
  • the outputs of these detectors are connected to an integrated circuit comprising a corresponding network of impedance converting circuits, a multiplexer, under the control of an address detector.
  • EP Patent 1 271 442 discloses a detection device which comprises an element for generating a state detection information, giving the state of an object in a plurality of predetermined regions, for example the chambers of a house, by means of sensors installed in each of these regions for detecting the movement of this object, and a region determining element in which the state detection information has changed to determine the state of said object in that region.
  • thermopile sensors are basically sensitive to a permanent radiative flux. They directly measure the temperature by means for example of a thermopile sensor and give an image in the field of vision.
  • the added value of a thermopile lies in its ability to detect the radiative flux from a person regardless of its attitude / behavior, unlike a pyroelectric sensor that can only detect a variation in radiative flux of an individual in movement.
  • An originality of the invention lies in the fact of associating with the sensor two processing algorithms: one using the amplified raw signal and measuring the static presence, the other realizing the derivative of the raw signal and detecting the movement.
  • An originality also lies in the fact of using displacement detection to calibrate the detection by erasing the influence of the thermal environment and its temporal variations.
  • each sensor comprises a motion detector associated with a presence detection module and a weak and slow motion detection module.
  • This detector motion can then be a piezoelectric sensor.
  • each sensor comprises a zero adjustment module for eliminating the influence of the thermal environment and its temporal variations.
  • the figure 1 illustrates a first example of the bi-functional sensor of the invention.
  • the figure 2 illustrates a second example of the bi-functional sensor of the invention.
  • the figure 3 illustrates an exemplary embodiment of a management system implementing such sensors of the invention.
  • the sensor 20 of the invention comprises a motion sensor, such as a piezoelectric sensor 21, which is associated with a first very sensitive processing module 22 for detecting the slowest and slowest movements (SD output) and a second less sensitive processing module 23 integrating the energy received over long periods to access the presence (SP output).
  • a motion sensor such as a piezoelectric sensor 21
  • SD output the slowest and slowest movements
  • SP output the presence
  • the sensor of the invention comprises a bolometric or thermopile presence sensor 31, which is fundamentally sensitive to the received radiation energy (input E), to which two processing modules 32 and 33 are associated, one amplifying the raw signal and measuring the received energy (SP signal), the other realizing the derivative of the raw signal to detect the movement (SD signal).
  • a zero adjustment module 34 which uses the displacement detection signal SD, makes it possible to achieve a zero of this detection by eliminating the influence of the thermal environment and its temporal variations.
  • Presence sensors of the same type can be used for both comfort and safety services.
  • the presence sensors may or may not be placed in all areas or rooms of the premises and inform at any time a central system of the situation of occupied rooms.
  • These real-time data can be associated with historical data: dates, times and, if necessary, additional data useful depending on the purpose of the service such as the instantaneous cost of energy, the outside temperature ...
  • the invention also relates to a method using such means.
  • any decision to trigger an alarm (signal S2) is based on an accurate analysis of the occupancy habits of the different zones or rooms of said premises to diagnose any abnormal behavior characterized by an individual.
  • the means of supervision of the two comfort and safety functions come to perform a filtering using a likelihood analysis.
  • a likelihood analysis For security, several factors are used: the decision to initiate a security surveillance, the detection of presence for the sensors and the said supervision that is to say the constitution of a likelihood analysis based on the habits of the occupants.
