Description

BACKGROUND OF THE INVENTION The invention relates to the field of home automation devices comprising in particular a sunshine sensor and in particular used in the management associated with residential or tertiary buildings. The subject of the invention is more particularly a method of operating the home automation device, said method comprising a so-called twilight detection step. The invention may also advantageously relate to a home automation device, as well as a home automation installation comprising such a device. STATE OF THE ART In the field of home automation, it is known to use a sunshine sensor to perform a twilight test in order to deduce in particular the passage from day to night, and to trigger the closure of shutters accordingly. . However, in certain configurations, it is possible for such a passage to be deduced from values derived from the sunshine sensor, whereas in reality this passage does not correspond to twilight. This is, for example, the case during very dark days, even stormy passages. There is then a risk that a twilight is incorrectly detected and the shutters are closed during the day, which goes against the wishes of the occupants of a building associated with shutters. To avoid such a problem, the documents FR2966942 and FR2966943 describe an inhibition of twilight tests as a function of data such as the temperature, or time slots defining the start time and the end time of this inhibition. In other words, twilight detection is enabled when the current time is outside this time range, while it is disabled when the current time is in the predefined time range. These solutions implement a precise real-time clock to know the current time and means to check the membership of this current time predefined time slots. In addition to the fact that setting up a real-time clock increases manufacturing costs, it can lead to errors and disturbances, especially during changes in winter / summer time or during power outages. In addition, the documents FR2966942 and FR2966943 describe a twilight detection means based on a measurement of one or more electrical parameters of a photovoltaic generator.

However, the spectral response of a photovoltaic generator is, according to its technology, different from that of the human eye, the twilight time detected by this means will be different from the time when the user will perceive the darkness. There will therefore be a time lag between the control of the home automation device and the moment when the user would like it to occur.

OBJECT OF THE INVENTION The object of the present invention is to propose a solution making it possible to simplify the twilight detection by avoiding the bad detections and by limiting the costs of implementation. The operating method of a home automation device comprising at least one sunshine sensor comprises: at least one step of detecting a first state assimilated by the home automation device at a twilight of an external environment; and a step of implementing and maintaining a first mode of operation of the home automation device during a period of time of predetermined duration, the beginning of the period of time being determined from at least one data item derived from the detection of the first state, said first mode of operation being configured so as to: o avoid the detection of a second state assimilated by the domotic device at a twilight of the external environment, and / or to prevent a passage of a first configuration to a second configuration of a first element of the home automation device in case of detection of a third state assimilated by the home automation device at a twilight of the external environment. Preferably, at the end of the lapse of time, a second mode of operation of the home automation device is implemented during which a step of detecting a fourth state assimilated by the home automation device at a twilight of the outside environment is preferably the detection steps of the first state and the fourth state are identical and temporally separated by at least said period of time. Advantageously, the step of detecting the first state comprises a step of receiving at least one signal from the sunshine sensor and a step of comparing a value representative of the at least one signal with a predefined threshold, which threshold having a first value in the first mode of operation and a second value, different from the first value, in the second mode of operation.

Preferably, the first value corresponds to a lower sun exposure than that associated with the second value. According to one implementation, the detection of the second state is avoided in the first mode of operation by inhibiting measurements made by said sunshine sensor or by inhibiting the use of measurements made by said sunshine sensor for the purpose of detect a twilight. The time interval (Ti) may have a duration of at least 23 hours and a maximum of 24 hours, preferably a duration of at least 23 hours and 45 minutes.

According to an improvement, the duration of the lapse of time and / or the beginning of the lapse of time are modified according to data coming from several successive steps of twilight detection out of the first mode of operation, preferably the successive stages of twilight detection. are separated in pairs by an implementation of the first mode of operation.

Furthermore, the method may include a step of resetting a system configured to determine a new value of start and / or duration of the lapse of time. According to one embodiment, the sun sensor comprising a photovoltaic module, the method comprises a step of using the photovoltaic module. For example, the use step comprises a first operating step in which the photovoltaic module is used as a sun sensor to enable twilight detection and a second operating step in which the photovoltaic module is used to recharge. a battery. According to one implementation, the method comprises a first phase of management of a twilight associated with a sunset and a second phase of management of a twilight associated with a sunrise, said second phase of management being independent to said first phase of management. Thus, the first management phase may comprise said at least one first state detection step and the first mode maintenance implementation step and the second management phase may comprise: at least one detection step by the domotic device of a fifth state corresponding to a sunrise; and a step of implementing and maintaining a third operating mode of the home automation device during a time period of predetermined duration, the beginning of the time period being determined from at least one data item derived from the detection of the fifth state, said third mode of operation being configured to: o avoid the detection of a sixth state assimilated by said home automation device to a sunrise, and / or to prevent a passage of a third configuration to a fourth configuration of a second element of the home automation device in case of detection of a seventh state assimilated by said home automation device at a sunrise. Advantageously, the method comprises a step of transmitting a state change signal to an actuating actuator of a mobile element of a home automation equipment for closing, concealment or screen associated with the device. home automation, including an activation signal of the actuator, this transmitting step being triggered by the detection of the first state while the home automation device is out of the first mode of operation. Preferably, the transmitting step is inhibited when the home automation device is in the first mode of operation. The invention also relates to a home automation device comprising software and / or hardware elements for implementing an operating method as described, said home automation device comprising an automation, a remote control or an electromechanical actuator. The invention also relates to a home automation installation comprising an actuator for operating a mobile element of a home automation equipment for closing, occultation or screen and a home automation device as described. Preferably, the installation comprises an element for implementing a delay between a reception of a detection signal of the first state emitted by the home automation device and the execution of a state change of the actuator. BRIEF DESCRIPTION OF THE DRAWINGS Other advantages and features will emerge more clearly from the following description of particular embodiments of the invention given by way of nonlimiting examples and represented in the accompanying drawings, in which: FIG. 1 schematically illustrates an embodiment of a method of operating a home automation device; FIG. 2 illustrates a particular step of twilight detection of the embodiment of the operating method of FIG. 1, FIG. 3 illustrates a particular embodiment of an installation capable of implementing the control and operating methods, FIG. 4 illustrates a chronology of implementation of an embodiment of the operating method. DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION One embodiment of the method described below differs from the prior art in particular in that it implements a lapse of time Ti (FIG. 4) in which a home automation device is maintained in a first mode of operation preventing the realization of a twilight detection step and that this period of time is a function of at least one signal from the sunshine sensor. Thus, it is possible to simplify the twilight detection by avoiding bad detections and by limiting the costs of implementation because it is no longer necessary to incorporate a real-time clock accurate and adjusted as in the prior art. Thus, as illustrated in FIG. 1, the operating method of a home automation device comprising at least one sunshine sensor comprises at least one step of detecting a first state El assimilated by the home automation device at a twilight of a external environment. By "dusk" is meant here the broad definition of the term in the sense that it may be a faint glow, or diffuse radiation, at sunrise or sunset. In other words, the state associated with twilight can be a sunrise or a sunset. However, the method is advantageously applied in the context of home automation systems for managing the automated closure of the equipment screens occultation (or shutters) when the sunset is detected. The method further comprises a step of implementing and maintaining a first mode of operation of the home automation device E2 over a period of time Ti (FIG. 4) of predetermined duration, the beginning of the period of time T1 being determined from at least one datum resulting from the detection of the first state El. The first mode of operation is configured so as to avoid the detection of a second state, which would be assimilated by said domotic device at a twilight of the external environment, and / or to prevent a passage from a first configuration to a second configuration of a first element of the home automation device in case of detection of a third state, which would be assimilated by said home automation device to a twilight of the external environment. In fact, it is understood that the second and third states correspond to conditions assimilated by the home automation device to those of a twilight while the outside environment is not in real conditions of dusk. These are therefore errors that must be avoided, which is implemented during the first mode of operation. In the case where the first operating mode is configured to avoid the detection of the second state assimilated by said home automation device at a twilight of the external environment, it is the sun sensor itself or the home automation device that prevents the detection or sending of a detection signal. In the case where the first operating mode is configured so as to prevent the passage from the first configuration to the second configuration of the first element of the home automation device when the third state assimilated by said home automation device is detected at a twilight of the environment outside, the home automation device receives a signal from the sun sensor. The home automation device could deduce twilight conditions when it is not really the case.

Insofar as the home automation device is in the first mode of operation, it then corrects the error by ignoring this signal. Preferably, the home automation device is in the first mode of operation only and throughout the period of time Ti. For example, the data resulting from the detection of the first state may be representative of the instant tO (FIG. 4) of effective detection of the first state, or a piece of data simply indicating that the first state has been detected.

The predetermined duration of the time can be modifiable. The first mode of operation can be implemented (that is to say that the time interval Ti can begin) as soon as the first state is detected (time t0), or after a delay following the detection of the first state, this period can be 30 minutes and adjustable by the user. This delay to postpone the implementation of the first mode of operation is of interest when the home automation device detects too early a twilight. Thus, this time can be adjusted to match the wishes of users.

The fact of being based on a time interval Ti whose start is a function of the detection of the first state allows the process to not need to know the actual date and current time. Thus, there is no need for a precise time base or particular parameterization at initialization. The first, second, and third states can be a sunrise or a sunset. The second and third states may be identical and associated with the same time instant. Preferably, the second and third states are shifted in time with respect to the first state. The external environment may be considered to be the exterior of a building or any environment to which the sun sensor is oriented to measure radiation, especially from the sun, in that environment. A sunshine sensor can generate a signal representative of the sun's radiation received by said sensor. In other words, any type of sensor capable of generating a signal making it possible to quantify the solar radiation received is suitable for the present method. Advantageously, at the end of the lapse of time Ti (that is to say when the home automation device leaves the first mode of operation), a second mode of operation of the home automation device is implemented E3 during which a step of detection of a fourth state E4 assimilated by said home automation device to a twilight of the external environment is achieved. Preferably the detection steps of the first state E1 and the fourth state E4 are identical (dashed output of the step E3 which returns to the step E1) and separated temporally by at least said period of time T 1. It is then understood that the method is iterative, that is to say that the fourth state detection step is in fact a new stage of detection of the first state that will be used to perform a new stage of implementation. implementation and maintenance of the first mode of operation. Thus, the first and fourth states may be identical but each associated with a different time instant. In the second mode of operation, tests may be performed at regular intervals or not in order to seek to detect the first or fourth state.

In other words, it is possible to have the following kinematic: the home automation device is in the second mode of operation and a first twilight is detected by a first implementation of the first state detection step, the first detected twilight triggers the transition from the second operating mode to the first operating mode of the home automation device during the predetermined period Ti. As a result of the time lapse Ti, the home automation device exits the first mode of operation and is placed again in the second mode of operation. A second twilight can then be detected by a second implementation of the first state detection step and this second twilight detected can in turn initiate the time lapse Ti by placing said home automation device again in the first mode of operation. , And so on. Preferably, when the first or fourth state is detected, a particular action is performed, for example a shutter closure. According to an embodiment illustrated in FIG. 2, the step of detecting the first state El, and therefore the fourth state, comprises a step of receiving at least one signal E1-1 originating from the sunshine sensor. Said at least one signal is, preferably, representative of a measurement of an electrical signal (for example voltage and / or current) generated by sun rays received by said sunshine sensor whose energy is transformed by the sunshine sensor for generating said signal. For this purpose, the sun sensor may comprise a photodiode, a photovoltaic panel, an electronic unit or other equivalent means for generating the said at least one signal. In addition, the step of detecting the first state El comprises a comparison step E1-2 of a value representative of the at least one signal at a predefined threshold. This predefined threshold has a first value v1 in the first mode of operation and a second value v2, different from the first value v1, in the second mode of operation. The difference between the first value and the second value makes it possible to implement the step in which the detection of the second state assimilated by said domotic device at a twilight of the external environment is avoided, in which case the first value can never be reached regardless of the solar radiation received by the sun sensor (for example the first value may be representative of a dark night). For example, if the sunshine sensor is capable of providing between OV (if no radiation) and 5V (full illumination), the threshold may have a first value v1 equal to -1V. In other words, the first value v1 may correspond to a lower sun exposure than that associated with the second value v2. It will be understood that in the first mode of operation associated with the step where the detection of the second state assimilated by said domotic device at a twilight of the external environment is avoided, the detection of twilight can be inhibited. Thus, the detection of the second state can be avoided in the first mode of operation by inhibiting measurements made by said sunshine sensor or by inhibiting the use of measurements made by said sunshine sensor in order to detect a twilight . This inhibition can be achieved either by a function preventing the measurement from the sunshine sensor, or by a function preventing the processing of this measurement or the transmission of the twilight detection information. Preferably, the time interval Ti has a duration of at least 23 hours and at most 24 hours, preferably a duration of at least 23 hours and 45 minutes. It is based on the following assumption: the duration of the day or a succession of a night phase and a day phase varies only a few minutes from one day to another. As a result, the twilight associated with a day in the year will occur approximately 24 hours after the twilight of the previous day. Any other detection of twilight during the period of time Ti initiated by a previous detection of the first state is therefore in principle a false detection. This solution also makes it possible to use a time counter that can be limited to 24 hours, which contributes to the simplicity and the reduction of the cost of the home automation device. The time interval Ti during which the first mode of operation is maintained can in particular be implemented by using a time base or an internal counter of a microcontroller of the home automation device.

During this period Ti, a limited energy can be dedicated to the operation of the home automation device. Most of the radiation received can be used to power the home automation device or any other equipment that would be connected to the sun sensor. According to an improvement, the duration of the lapse of time Ti and / or the beginning of the lapse of time Ti can be modified as a function of data resulting from several successive steps of detection of twilight (in particular of first states) out of the first mode of operation, preferably the successive steps of twilight detection are separated in pairs by an implementation of the first mode of operation. For example, it is possible to record and use the actual durations between two detected twilights (two second states), an average of these previous times then being used to adjust the duration of the lapse of time. Thus, it is possible to use a decision-making database which is enriched each time the first state is detected, making it possible to adapt the duration of the lapse of time and / or the beginning of the lapse of time over the evolution of the duration of the day as the seasons go by. Therefore, in general, it is understood that the principle of the present method requires only "good detection" at the first twilight after activation by a user.

However, to remedy a bad configuration of the first twilight time, a reset of the home automation device by the user is possible, for example by erasing the history of the data from the first previous states through a deactivation / reactivation of the home automation device. The device can then be reprogrammed. In other words, the method may comprise a reset step E5 (FIG. 1) of a system configured to determine a new start and / or duration value of the lapse of time. For example, this reset may correspond to the erasure of at least one datum associated with the detection of at least a first previous state stored in a memory of the system. Advantageously, the sun sensor comprises a photovoltaic module, and the method comprises a step of using the photovoltaic module. Thus, the use step comprises a first operating step in which the photovoltaic module is used as a sun sensor to enable a twilight detection and a second operating step in which the photovoltaic module is used to recharge a light. drums. These two operating steps can be chained cyclically during the same operating mode of the home automation device (in particular the second mode of operation), or can each be dedicated to a mode of operation of the home automation device. For example, it is possible to use the open circuit voltage of the photovoltaic module to deduce therein information of sunshine (that is to say the signal coming from the sensor), in particular in the second, or the first, mode Operating. This information can then be used to automatically close a shutter at night, for example. When the home automation device is in the first mode of operation having a recovery range with a day phase, the energy supplied by the photovoltaic module can be mostly used to store the energy required for the automatic closing by the actuator following a twilight detection in the second mode of operation. As mentioned before, the twilight can be a sunrise or a sunset. According to one improvement, the method can independently process the detection of a sunrise and a sunset. In other words, the method may comprise a first phase of management of a twilight associated with a sunset and a second phase of management of a twilight associated with a sunrise, said second phase of management being independent of said first phase Management. It is possible to detect sunrise and sunset twilight from the same sunshine sensor, while limiting unwanted twilight detections and limiting the energy consumption dedicated to these twilight detections. According to a particular implementation of the first and second phases, the first management phase comprises said at least one step of detecting the first state and the step of carrying out the maintenance of the first mode of operation for a period of time Ti. It is therefore understood that the first, second and third states are representative of a detection by the home automation device that can correspond to a sunset. In addition, the second management phase comprises: at least one step of detection by the home automation device of a fifth state corresponding to a sunrise; and a step of implementing and maintaining a third mode of operation of the home automation device during a time period T2 (FIG. 4) of predetermined duration, the beginning of the time period being determined from at least a data t2 (Figure 4) resulting from the detection of the fifth state. The third mode of operation is configured to avoid the detection of a sixth state assimilated by said home automation device to a sunrise and / or to prevent a passage from a third configuration to a fourth configuration of a second element of the home automation device in case of detection of a seventh state assimilated by said home automation device at a sunrise. The sixth and seventh states can be identical and associated with the same time instant. The sixth and seventh states can be shifted temporally from the fifth state. The first and second elements of the home automation device may be an actuator and be the same or different. Thus, the first and second modes of operation and the third and fourth modes of operation of the home automation device can then overlap, without a sunset twilight detection being disturbed by the other sunrise twilight detection. , as it appears in FIG. 4. Moreover, all that has been said above can also be realized in the second management phase by replacing the first, second, third and fourth states respectively by the fifth, sixth, seventh and eighth state.

According to an embodiment illustrated in FIG. 1, the method may comprise a step E6 of transmitting a state change signal to an actuating actuator of a movable element of a home automation closing device, occultation or screen associated with the home automation device. This change signal may in particular be an activation signal of the actuator. This emitting step E6 is triggered by the detection of the first state El (dotted at the output of step E1) while the home automation device is out of the first mode of operation or by the detection of the fourth state E4. Upon receipt of this signal, the actuator can be activated, for example to achieve the closure of a shutter in case of detection of a first state representative of a sunset. In the case of detection of a sunrise, an opening of the shutter will be implemented. Preferably, the transmission step is inhibited when the home automation device is in the first mode of operation, or if it is not inhibited it is the action of the actuator which is inhibited on reception by the actuator of said state change signal. In general, a home automation device may be an object of the invention, in particular the home automation device may comprise software and / or hardware elements for implementing the method as described above in its various implementations or embodiments, said device comprising an automation, a remote control or an electromechanical actuator. It is understood that the home automation device can comprise as many elements as the method comprises steps so that each element of the home automation device is configured to perform the step with which it is associated. The home automation device may consist of a single housing comprising all the elements, or comprise separate units, such as a sun sensor on the one hand and a remote control on the other hand. A home automation installation comprising an actuating actuator of a mobile element of a home automation equipment for closing, occultation or screen and a home automation device as described may be subject of the invention. The actuator can be an integral part of the home automation device. He then understands the hardware and software to receive the signal from the sun sensor and compare the signal to an associated threshold to detect a twilight. It can also include the means to operate in a first and a second mode. The actuating actuator may be the first and / or second element of the device as referred to above. The home automation equipment can then be a component allowing, for example to hide, all or part of an opening of a building. The installation then comprises the means for detecting a twilight and for triggering the closure of the home automation equipment closing, occultation or screen during a detection of twilight (including a sunset) in the second mode Operating. Advantageously, the installation comprises an element for implementing a delay between a reception of a detection signal of the first state emitted by the home automation device and the execution of a state change of the actuator. Thus, during the detection of twilight, the actuator can change state at the end of a delay defining a time delay. In fact, a sunshine sensor and more particularly based on photovoltaic module does not have the same spectral response as the human eye. Consequently, when twilight is detected from the open circuit voltage of the photovoltaic module, this instant of detection does not necessarily correspond exactly to the time at which the users would like to close a shutter. Therefore, in order to prevent the shutter from closing too early, it is necessary to add a duration (for example 30 minutes) from the instant of detection of the twilight before closing the shutter. This timer is either managed by an element of the installation, or as previously mentioned directly by the home automation device itself. FIG. 3 illustrates a particular installation comprising a sun sensor 1 oriented so as to cooperate with the radiation of the sun 2. This sun sensor 1 is connected to a battery 3 to recharge it and the battery 3 is connected to the actuator 4 to provide electricity in case of actuation. The sun sensor 10 can charge the battery over water according to available solar radiation. In this example, the sensor 1, the battery 3 and the actuator 4 are part of the home automation device.
