Description
Technical Field
The present invention relates to a method for detecting the initiation of commands given to electrical and electronic devices.
More particularly, the present invention relates to a method for detecting a response showing that a command previously sent to an electric/electronic device has been efficiently executed (implemented).
The present invention generally refers to the field of electrical/electronic control devices for home automation systems.
Background
The current state of the art makes it possible to improve various aspects related to the home and the general environment, such as the quality of life of people, organization, management costs and the safety of the surrounding environment, thus also simplifying the maintenance and management of said surrounding environment.
A typical example is a "smart" or "intelligent" electrical system which allows not only to control when and how household appliances, such as household appliances, windows, lighting systems, etc., are used, but also to monitor their parameters, such as energy consumption, via electronic circuits already widely used in existing solutions.
However, the systems are programmed to receive commands, such as turning on a light bulb or opening or closing a window or door, or monitoring consumption, but they do not provide a response signal that ensures that the command has been sent for a real implementation.
For this purpose, according to the invention, suitable parameters of the household appliance to be controlled are selected and the time variation of said parameters is monitored to generate a feedback signal; preferably, the parameter is circulating amperage or instantaneous power.
In fact, the trend of the activation signal measured over time has anomalies that can be found when the command is not executed or is partially or erroneously carried out by the device.
Conversely, when the command is executed correctly, the trend of the actuation signal measured over time is known and corresponds to the expected trend.
In this way, it is possible to detect any malfunction or problem simply by comparing the profile of the measured activation signal with the profile of the expected activation signal.
The remote control appliances of "smart" devices are known to have miniaturized electronic components equipped with specific executive programs and/or algorithms (firmware) which manage the wireless communication and which allow the central unit to drive a plurality of connected devices via a communication protocol.
Disclosure of Invention
By using suitable firmware, according to the invention, the device can be made to learn, for example, a specific trend of the current flowing through the load (actuator); additionally, actuators are initially configured by the manufacturer via a graph showing the electronic behavior of the actuator (such that the graph is compared to a real graph of the current flowing through the load to have a real indication of how well the command is being executed); in any case, the electronic behavior of the actuator will signal the user.
It is thus an object of the present invention to determine, via an algorithm implemented in the firmware of a "smart" device, that a command sent by a user to one or more devices of a home automation system has been effectively carried out.
Another purpose of the present invention is to evaluate any anomalies that prevent the implementation of commands or of the devices connected to the home automation system (fault, failure and/or breakage conditions).
Yet another object of the present invention is to provide a method for detecting the real execution of commands sent to an electrical/electronic device by using known electrical and/or electronic circuits, which have been used so far only for monitoring the consumption of electricity and/or the absorption of electricity; the method is therefore easy to implement in known home automation systems, which can also be enhanced with new functionalities.
Finally, it is an object of the present invention to provide a system for detecting the actual execution of commands sent to electrical/electronic devices and for detecting any operating anomalies; the system is easy, fast and practical both for the supplier of the maintenance service and for the equipment manufacturer and for the end user.
The above objects and others are achieved, according to the appended claim 1, by a method for detecting the initiation of a command given to an electrical and electronic device; further technical details are set forth in the dependent claims.
Detailed Description
The present invention will now be described for purposes of illustration and not limitation, in accordance with preferred embodiments of the invention.
According to the invention, the method for detecting the initiation of a command given to an electrical and electronic device is advantageously based on the reading of suitable parameters, preferably the current absorbed by the electrical/electronic device during its operation, in order to detect whether the command given to the device is executed effectively.
In fact, a circuit for measuring the current consumption is used; the circuit allows to know the current draw of the device over time in order to assess whether a command is being executed efficiently by the device in a correct and complete manner.
In particular, the use detection function is started from a signal constituted by the current absorbed at a "smart" power outlet (said outlet is also able to monitor the power consumption).
Currently known devices are programmed, also in co-operation with the home automation system to which they belong, to monitor the current consumption (with the aim of monitoring and reducing the consumption), but do not provide a response signal capable of guaranteeing the actual implementation that the command has been sent.
The technical solution that is the object of the present invention comprises the same circuit and/or device for monitoring energy consumption to know the power absorption dynamics of the device; in this way, the system of the invention is able to evaluate, via a specific algorithm present in the device firmware, whether the command has been correctly converted into a physical actuation carried out by means of said driven electrical/electronic device (said device, belonging to the home automation system, allows not only to turn on the electric lights, but also to close doors, windows, shutters, gates, etc., and for this it is necessary to ensure that the command sent by the system has been converted into a complete physical action made by the electrical/electronic device).
As an example, for a common light bulb used at home, according to the invention, the action of turning on and off the light bulb is confirmed by reading a typical current signal previously set for the light bulb, whereas known systems only detect a change of state from "off" to "on" and vice versa (by means of an electronic control unit) and they are not able to confirm whether the light bulb is actually "on" or "off" (for example, if the light bulb is faulty, the control unit of the known system will display the "on" state when the light bulb has been driven on).
According to the method of the invention, a graph showing a standard trend of the power consumption of the load over a period of time is executed after learning the power consumption of the load under standard use conditions (which constitutes the starting device), and the graph is advantageously compared with the trend of the power consumption measured directly on the load when a command has been sent to the device.
For example, if a light bulb is damaged and stops its operation, the system according to the invention is able to detect a difference in the power consumption of the light bulb with respect to a standard trend, i.e. fails to exceed a minimum threshold value for the expected average power consumption, and thus the system is able to generate an alarm signal.
Another typical example is constituted by an automatic system for opening and closing shutters, which has a current trend with an initial peak or starting point, an average consumed current and a final peak, corresponding to reaching the closing limit within a constant average time.
When the command is initiated, the current trend can be used to find any anomalies, while the final peak is used as feedback data for the closing limit, so that the user is informed that the command has succeeded and that the correct mechanical control embodiment has been executed; if for any reason said execution does not occur, such as for example due to a failure of the assembly of the device or due to the presence of an object between the shutter and the limit switch, the trend of the current will have a shorter duration and will have a different type of modulation trend with respect to the expected trend already known by the system.
Furthermore, the system is also able to detect discrepancies and to signal an anomaly to the user via a communication device already present in known home automation systems.
In particular, the current changes in normal and normative operating conditions are compared with the current changes occurring in abnormal conditions, and the system sends an alarm signal because the changes are different from the changes of automatic self-learning.
In fact, this is a difficult problem to modify the use of read sink current by using specific algorithms and/or firmware that are able to monitor the current sink, and are now used only for calculating the power consumption; the circulating current is estimated by the effect of the applied load in order to generate feedback signals related to the physical phenomena intended to be controlled (opening of the bulb, closing of the door, closing of the valve, etc.). It should be noted that electronic controls of home automation systems are often sent to remote devices and sites (from work sites to homes, from main houses to vacation houses, etc.), and these conditions do not allow direct checking of the actual drive of commands.
Furthermore, the system is able to define a normal standard trend of the current and compare it with the current trend measured during the subsequent command; if there are any differences that exceed the average expected current draw threshold, the system sends an alert signal regarding possible critical issues and developing anomalies (predictive diagnostics); the alarm signal can also be used by the manufacturer and by the supplier of the maintenance service (which can allow intervention before more serious or forbidden faults occur), whereas if the current trend complies with the standard trend, the system can guarantee and prove that the transmitted command has been correctly implemented and that the device operates within the specifications given by the quality standards.
From the foregoing description, the characteristics of the method for detecting the actuation of a command given to an electrical/electronic device, and the related advantages, are clear.
Finally, the present invention has been described for illustrative purposes and not for restrictive purposes, according to preferred embodiments, but it is to be understood that variations and/or modifications may be made by those skilled in the art without thereby departing from the relative scope of protection of the appended claims.
