Description

Title of the invention: Diagnostic method for a motorized drive device for a blackout device of a closure, blackout or solar protection installation.

[0001] The present invention relates to a diagnostic method for a motorized drive device for a shading device of a closure, shading or solar protection installation, as well as a motorized drive device adapted to implement this diagnostic method.

[0002] In general, the present invention relates to the field of blackout devices comprising a motorized drive device moving a screen, between at least a first position and at least a second position.

[0003] A motorized drive device includes an electromechanical actuator of a movable closing, obscuring or sun protection element, such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter referred to as a screen.

[0004] It is known to use a motorized drive device comprising an electromechanical actuator and an electrical power supply device including a battery and a photovoltaic panel. In such a solution, the photovoltaic panel is used to recharge the battery so that it is always sufficiently charged to power the electromagnetic actuator.

[0005] When situations repeatedly occur in which the battery does not contain enough energy to power the electromechanical actuator, there is a problem with the installation. Photovoltaic panels and batteries are components that degrade over time. Consequently, in a malfunction situation, installers may be inclined to replace the photovoltaic panel and / or the battery. However, the origin of the malfunction may lie elsewhere in the installation. In particular, the malfunction may originate from: - a change in the installation's environment (construction of a new building, planting of new vegetation, growth / development of existing vegetation) resulting in a greater proportion of the sunlight directed towards the photovoltaic panel being blocked, and / or - soiling of the photovoltaic panel, and / or - an increase in resistance to movement of the shading device due for example to fouling or aging of its guidance.

[0006] In such circumstances, replacing the photovoltaic panel and / or battery is ineffective and other actions must be implemented to solve the problem.

[0007] The present invention aims to overcome the aforementioned drawbacks and to provide a diagnostic method that improves the situation. In particular, the invention provides a diagnostic method that makes it possible to determine the condition of the photovoltaic panel.

[0010] The method may include, depending on the result of the first comparison step, a communication, in particular a display, of information on the production of electrical energy.

[0011] The method may include: - a step of measuring the electrical energy consumed by the motorized drive device during the target period, and - a step of determining the electrical energy consumed by the motorized drive device during the target period.

[0012] The method may include a second step of comparing the electrical energy produced by the photovoltaic panel during the target period to the electrical energy consumed by the motorized drive device during the target period.

[0013] The method may include, depending on the result of the second comparison step, communication, including display, of an energy balance indicator and / or a recommendation for action to improve the balance indicator.

[0014] The target period may have: - a short duration, between 3 and 9 days, for example a period of approximately 5 days, or - an intermediate duration, between 10 and 31 days, for example a period of approximately 25 days, or - a significant duration, between 32 and 100 days, for example approximately 80 days.

[0015] The process may include a combined analysis step of at least two results from the second comparison step for different target periods of short, medium and / or long duration.

[0024] First, with reference to Figures 1 and 2, an installation 100 comprising a closing, shading, or solar protection device 3 according to an embodiment of the invention is described. This installation 100, installed in a building (not shown), has an opening 1 in which a window 40 or a door (not shown) is located.

[0148] Here, the mobile terminal 33 can be the local control unit 12 and include all or part of the elements constituting it.

[0149] Preferably, the mobile terminal 33 is a smart phone, also called a "Smartphone" in English.

[0163] The mobile terminal 33 or the installation 100 includes all the hardware and / or software components necessary for implementing the compatibility verification method that is the subject of the invention, as described below. The components may include software modules.

[0164] Two variants of an embodiment of a diagnostic method for the motorized drive device 5 for the shading device 3 of the installation 100 for closing, shading or solar protection according to the invention and represented in Figures 1 to 3 are now described with reference to Figures 4 to 8.

[0165] The diagnostic process is advantageously implemented by the motorized drive device 5 itself, in particular by the electromechanical actuator 11 and / or by the electrical power supply device 26 and / or by the mobile terminal 33 and / or by a control unit 12, 13. Thus, the diagnostic process can be: - implemented at the level of an element of the training device, or - distributed between several elements of the training device, different actions of the diagnostic process being implemented at the level of different elements of the training device, the result of one or more actions implemented by one element of the training device being transmitted to another element of the training device.

[0166] The diagnostic process is advantageously implemented by an application, in particular a mobile terminal application 33.

[0167] The application allows users to check the condition (health status) of the photovoltaic panel. This application operates using limited computing resources. Indeed, the process can be summarized, as will be seen below, as follows: - perform time integrations of the electrical power produced by the photovoltaic panel 25 (and possibly of the electrical power consumed by the motorized drive device 5), - retain only data over a limited target period and - to carry out a comparison to obtain a diagnosis, in particular a generalized diagnosis over time based on the data retained.

[0168] The diagnostic procedure includes: - a step S100 for counting the electrical energy produced by the photovoltaic panel 25 during one elementary period, this step S100 being iterated over several successive elementary periods, and - a step S200 of determining the electrical energy produced by the photovoltaic panel 25 during a target period equal to a sum of elementary periods, in particular to a sum of a succession of elementary periods.

[0169] The target period preferably has: - a short duration, between 3 and 9 days, for example a period of approximately 5 days, or - an intermediate duration, between 10 and 31 days, for example a period of approximately 25 days, or - a significant duration, between 32 and 100 days, for example approximately 80 days. This target period is preferably a rolling period, that is to say a period of n days preceding the current day (with n an integer).

[0170] The counting step S100 advantageously includes a determination S130: - the electrical power supplied by the electrical panel during a basic time interval, or - of the electrical energy supplied by the electrical panel during this elementary time interval.

[0171] This determination of electrical power or electrical energy can be carried out by determining, measuring, or estimating the following values: - the voltage delivered during the elementary time interval (SI step 10), and - the current delivered during the elementary time interval (step S120).

[0172] These values ​​can be determined in the electrical power supply device 26, in particular by storage and processing in a logic processing unit of the electrical power supply device 26.

[0173] This S130 determination may include a multiplication of values: - tension, - of current, and - the duration of the elementary interval in order to determine an elementary electrical energy delivered during the elementary time interval.

[0174] The duration of the elementary time interval can be on the order of a second or a few seconds (typically 10 s to 60 s) or on the order of a minute or a few minutes (typically 1 min to 10 min).

[0175] Step S140 consists of aggregating the values ​​determined during steps S130 over elementary periods, an elementary period being the sum of the elementary time intervals, and calculating a sum of these determined values ​​which is an energy value, called the aggregate energy value.

[0176] The elementary period is in particular equal to 24h.

[0177] During an S150 step, the aggregate energy value determined at the end of the elementary period is recorded in a first memory.

[0178] Step S200 for determining the electrical energy produced by the photovoltaic panel 25 during the target period includes: - a step S210 in which the aggregate energy value determined during step S150 is recorded in a second memory, and a step S211 in which the oldest record of aggregate energy value in memory is erased (advantageously, the new record overwrites the oldest record), and - a step S220 in which the sum of the determined aggregate energy value records located in a second memory is calculated, the sum of the durations of the elementary periods being equal to the duration of the target period, the sum of the aggregate energy values ​​being equal to the electrical energy produced by the photovoltaic panel 25 during the target period. This second memory advantageously has a sufficient number of record locations, at least equal to the number of elementary time periods forming the target period.

[0179] The first memory therefore contains a history of aggregated energy values ​​determined at the end of the different elementary periods; the first memory thus contains historical data, i.e., a history of values. The first memory contains the most recent available aggregated values.

[0180] Then, in a step S500 of a first variant of the embodiment of the process (variant shown in Figures 5 and 7), the following are compared: - the value of electrical energy produced by the photovoltaic panel 25 during the target period (obtained at the end of step S200), at - at least one energy threshold value associated with the target period and determined during of an S300 stage.

[0181] In the first embodiment, in step S300, the threshold energy value associated with the target period is a theoretical value corresponding to a theoretical consumption of the motorized drive device 5 during the target period.

[0182] This theoretical value can be fixed in an S300 step, for the entire service life of the installation or for a limited period. In this case, the theoretical value is updated periodically. The theoretical value is determined based on the characteristics of the installation 100, in particular based on: - the nature or function of the screen, and / or - the screen mass, and / or - the screen dimensions, and / or - the power of the electromechanical actuator, and / or - the age of the installation.

[0183] Several theoretical values ​​can be determined, such as: - a high theoretical electrical energy consumption of the motorized drive device 5 determined by assuming high electrical energy consumption, and / or - a nominal theoretical electrical energy consumption of the motorized drive device 5 determined by making an assumption of nominal electrical energy consumption, and / or

[0184] - a low theoretical electrical energy consumption of the device motorized drive 5 determined by assuming low electrical energy consumption.

[0185] Comparing the results of steps S200 and S300 allows us to provide, in a step S510, a theoretical production indicator.

[0186] Then, in a step S600, in the first embodiment, depending on the result of the comparison step S500, the process communicates, in particular by displaying, information on the relative production of electrical energy. This information is preferably qualitative, such as the following: - good: if the production of electrical energy is greater than the theoretical electrical energy consumption of the motorized drive device 5 determined by assuming high electrical energy consumption, - average: if the production of electrical energy is greater than the theoretical electrical energy consumption of the motorized drive device 5 determined by assuming a nominal electrical energy consumption, - low: if the electrical energy production is less than the theoretical electrical energy consumption of the motorized drive device 5 determined in assuming a nominal electrical energy consumption,

[0187] - insufficient: if the production of electrical energy is less than the consumption theoretical electrical energy of the motorized drive device 5 determined by assuming low electrical energy consumption.

[0188] Steps S100 and S200 can be implemented in a loop over each corresponding interval or period. After step S600, the process then loops to a new step S500, which is implemented with the updated values ​​from steps S100, S200, and S300.

[0189] If, after implementation of the recommendations and after the expiry of a new target period, the relative production information remains insufficient, the process concludes that the photovoltaic panel is damaged and emits information indicating this condition of the photovoltaic panel. The user or installer can then replace the photovoltaic panel.

[0190] In a step S500 of a second variant of the embodiment of the process (variant shown in Figures 6 and 8), the following are compared: - the value of electrical energy produced by the photovoltaic panel 25 during the target period (obtained at the end of step S200), at - at least one energy threshold value associated with the target period and determined during an S400 step.

[0191] In step S400 of the second variant, the threshold energy value associated with the target period is an effective value corresponding to the actual consumption of the motorized drive device 5 during the target period.

[0192] To do this, the diagnostic procedure includes: - a step S410 which here is a step for counting the electrical energy consumed by the motorized drive device 5, in particular by the electromagnetic actuator 11, during the elementary period, and - a determination step S420 of the electrical energy consumed by the motorized drive device 5, in particular by the electromagnetic actuator 11, during the elementary period.

[0193] The counting step S410 advantageously includes a determination S412: - the electrical power consumed by the motorized drive device 5 during the elementary period, or - of the electrical energy consumed by the motorized drive device 5 during the elementary period.

[0194] This determination of electrical power or electrical energy can be carried out by determining, measuring, or estimating the following values: - the voltage and / or current supplying the motorized drive device 5 during the motor supply periods over a target period. The S410 counting step also includes an S413 step for determining a so-called standby consumption value during periods in which the motor is not powered.

[0195] These values ​​can be determined in the electrical power supply device 26, in particular by processing in a logic processing unit of the electrical power supply device 26.

[0196] This S412 determination may include a multiplication of values: - supply voltage, - of current consumed, and - the duration of the engine power supply periods in order to determine the electrical energy consumed during the elementary period.

[0197] Step S420 of determining the electrical energy consumed by the motorized drive device 5 during the target period includes: - a step S422 in which the energy value determined during the last implementation of step S410 is recorded in a third memory, and a step S423 in which the oldest energy value record in memory is erased (advantageously, the new record overwrites the oldest record), and - a step S424 in which the sum of the energy value records located in the third memory is calculated, the sum of the durations of the elementary periods being equal to the duration of the target period, the sum of the energy values ​​being equal to the threshold value of electrical energy consumed by the motorized drive device 5 during the target period. This third memory advantageously has a number of record locations that determines the target period as the product of the number of record locations and the duration of an elementary period.

[0198] Comparing the results of steps S200 and S400 allows us to provide an energy balance indicator in step S520.

[0199] In step S600, depending on the result of the comparison step S500, the process communicates, in particular by displaying an energy balance indicator. The indicator is, for example, based on the ratio of: - the energy produced by the photovoltaic panel during the target period, on - the energy consumed by the motorized drive device 5 during the target period.

[0200] If the ratio is less than 1, the method may include a communication action to indicate that energy production is insufficient and / or display recommendations such as cleaning the photovoltaic panel and / or moving the photovoltaic panel.

[0201] If the ratio is greater than 1, the process may include a communication action to indicate that energy production is sufficient.

[0202] Steps S100, S200, and S400 can be implemented in a loop over each corresponding interval or period. After step S600, the process then loops to a new step S500, which is implemented with the updated values ​​from steps S100, S200, and S400.

[0203] If, after implementation of the recommendations and after the expiry of a new target period, the ratio remains less than 1, the process concludes that the photovoltaic panel is damaged and emits information indicating this condition of the photovoltaic panel. The user or installer can then replace the photovoltaic panel.

[0204] Regardless of the embodiment variant, in step S600, the communication may include, as an alternative or in addition to qualitative information, quantitative information such as the value of electrical energy produced by the photovoltaic panel 25 during the target period and / or a recommendation for action to improve the balance indicator and / or a recommendation for action to increase the electrical energy produced by the photovoltaic panel 25 during the target period.

[0205] Preferably, step S600 is implemented at the request of the user or installer. If no request is made by the user or installer, the process can loop back to a new step S500, in which case step S600 is optional.

[0206] Regardless of the execution method or variant, different calculations can be performed, including any combination of the following calculations on the basis of historical data: - Calculation of the total energy produced by the 25 photovoltaic panel over a short period (e.g., 5 days), - calculation of the total energy produced by the photovoltaic panel 25 over an intermediate period (for example 25 days), - calculation of the total energy produced by the 25 photovoltaic panel over a long period (for example 80 days), - calculation of the total energy consumed by the motorized drive device 5 over an intermediate period (e.g., 25 days), - calculation of the total energy consumed by the motorized drive device 5 over a long period (e.g. 80 days).

[0207] Data stored over a short period of time corresponds to a short history, data stored over an intermediate period of time corresponds to an intermediate history, data stored over a long period of time corresponds to a significant history.

[0208] The use of a large history (80 days for example) is ideal in terms of Reliability of analysis. However, it requires more embedded data (which impacts the design and hardware resource requirements, particularly memory and computing resources) and has the disadvantage of not being immediately available: it takes 80 days to access such historical data and therefore to be able to use it. Furthermore, using a large historical dataset increases the risk of processing and considering data that has been corrupted by interventions on the installation (such as battery charging or replacement).

[0209] Using an intermediate history (25 days for example) is advantageous because it offers a good compromise with respect to the following parameters: - reliability, - availability time and - material resource requirements.

[0210] The use of a short history (5 days for example) is interesting because it allows good responsiveness of the device to current ambient parameters.

[0211] Preferably, the joint uses of a major history and an intermediate history or of a short history and an intermediate history or of a short history and a major history or of the three short, intermediate and long histories are implemented.

[0212] Indeed, several strategies can exploit different situations mentioned above.

[0213] Production over a short period, in the example below five days, could be used to quickly detect a problem with a photovoltaic panel that is no longer producing at all or very little: - The energy produced over five days is below a low threshold: we can deduce that production was non-existent during the last few days. For example, there may be a problem with the connection or shading of the cells in photovoltaic panel 25. - The energy produced over five days is above a low threshold: we deduce that the photovoltaic panel 25 is producing energy correctly.

[0214] Production over an intermediate period, in the example below 25 days, could be used to assess the quantity produced over the last rolling month approximately. It could be described as follows: - Good: if production is greater than a theoretical consumption associated with an installation corresponding to an unfavorable consumption; - Average: if production is greater than a theoretical consumption associated with an installation corresponding to a nominal consumption; - Low: if production is less than a theoretical consumption associated with an installation corresponding to a nominal consumption.

[0215] Production over a long period, in the example below 80 days, could be used to assess the quantity produced over the last rolling quarter approximately. It could be described as follows: - Good: if production is greater than a theoretical consumption associated with an installation corresponding to an unfavorable consumption; - Average: if production is greater than a theoretical consumption associated with an installation corresponding to a nominal consumption; - Low: if production is less than a theoretical consumption associated with an installation corresponding to a nominal consumption.

[0216] Cross-analysis of 25-day and 80-day production data makes it possible to distinguish between a problem related to usage and / or the season and a technical problem. If the 25-day production indicator is low while the 80-day indicator is good, it is highly probable that the production decrease is due to a period of bad weather or winter, unrelated to a malfunction of the installation.

[0217] If the 80-day production indicator is poor, there is potentially a problem related to the panel (positioning, cleanliness) or overuse in general. There is a high probability that the problem will persist even during a period of more favorable weather.

[0218] Regardless of the execution method or variant, an energy balance indicator produced by comparing energy produced and energy consumed, as previously described, can be calculated and used. In the same way as previously described for energy production values, the calculation and use can be performed over two target periods (e.g., 25 days and 80 days, as previously described).

[0219] Here again, cross-analyzing balances with different histories makes it easier to establish the origin of a potential problem. If the long-term balance (80 days) is poor, intervention is usually almost mandatory to avoid malfunctions.

[0220] Cross-analysis of energy balances with theoretical production analysis also allows for refining the analysis and also for producing effective automatic alerts to anticipate breakdowns.
