[0002] As society changes, the proportion of seniors choosing to live in their own homes continues to increase, driven by factors such as declining birthrates, longer life expectancy, greater economic independence, and a greater emphasis on quality of life in retirement. However, seniors living alone, who are in good health and capable of self-care, have a strong sense of autonomy in maintaining their personal privacy. Consequently, they find it difficult to accept standard home care systems on the market, such as those utilizing surveillance cameras, and may even reject their installation.

[0003] Therefore, in order to balance the privacy of home life and home care functions for users such as the elderly, how to come up with a method to monitor the usage of electrical appliances to effectively predict the daily life of users has become one of the issues that relevant industries currently want to solve. Summary of the Invention

[0004] An object of the present invention is to provide a field monitoring method and system and a socket device based on the usage of electrical appliances, which can overcome at least one disadvantage of the prior art.

[0005] The present invention provides a field monitoring method based on appliance usage, suitable for monitoring an electrical device used in a field. The method utilizes a communication-capable outlet device electrically connected to a power grid and the electrical device, and a management server capable of communicating with the outlet device. The management server stores user data related to at least one user in the field, as well as device data and historical usage data related to the electrical device. The outlet device stores current signature data related to multiple reference operating currents of the electrical device under different operating modes. The method includes the following steps: (A) the management server analyzes the user data and the historical usage data based on multiple characteristic parameters associated with the at least one user, the electrical device and the environment in which the electrical device is located and uses a machine learning algorithm to summarize multiple behavioral characteristics of the field on the usage behavior of the electrical device and establish a behavioral characteristic recognition model for identifying the behavioral characteristics; (B) the socket device continuously detects the current flowing through the electrical device and the environmental conditions in which it is located, generates event data related to the usage of the electrical device based on the current characteristic data and the detection results, and transmits the event data to the management server via a communication network; (C) the management server uses the behavioral characteristic recognition model to determine whether the event data from the socket device matches at least one of the behavioral characteristics; and (D) when the management server determines that the event data does not match any of the behavioral characteristics, it sends a warning message to at least one user terminal associated with the at least one user.

[0006] The field monitoring method based on the usage of electrical appliances of the present invention further includes the following steps after step (B): (E) when the management server receives the event data from the socket device, it stores the event data and incorporates the event data into the historical usage data; (F) the management server determines whether the reference working currents related to the electrical equipment need to be adjusted based on the event data and the device data; (G) when the management server determines that at least one of the reference working currents needs to be adjusted, it generates corresponding adjusted current characteristic data and transmits the adjusted current characteristic data to the socket device; and (H) when the socket device receives the adjusted current characteristic data from the management server, it updates the current characteristic data with the adjusted current characteristic data.

[0007] In the field monitoring method based on the usage of electrical appliances of the present invention, in step (B), the socket device also determines whether the electrical equipment is operating in a normal state or an abnormal state based on the detection result and the current characteristic data, and when it is determined that the electrical equipment is operating in an abnormal state, generates a warning output for indicating the abnormal state, or interrupts the power supply to the electrical equipment.

[0008] The present invention provides a field monitoring system based on electrical appliance usage, which is suitable for monitoring an electrical appliance used in a field and includes a routing device, a socket device, and a management server.

[0009] The routing device is suitable for being arranged in the field, and is used for connecting to a communication network and supporting a short-range wireless communication function.

[0010] The socket device includes a socket module, a connection module, a storage module, a current detection module, a temperature sensing module, and a processing module. The socket module is used to electrically connect the electrical device to a power grid, and can be operated to allow a power supply from the power grid to be supplied to the electrical device, or to interrupt the supply of the power supply. The connection module operates to electrically connect to the routing device or to communicatively connect to the routing device or the communication network. The storage module stores current characteristic data of multiple reference working currents of the electrical device in different operating modes. The current detection module is electrically connected to the socket module and operates to continuously detect the current flowing through the electrical device to generate a current detection result. The temperature sensing module operates to continuously sense the ambient temperature to generate a temperature sensing result. The processing module is electrically connected to the socket module, the connection module, the storage module, the current detection module and the temperature sensing module, receives the current detection result from the current detection module and the temperature sensing result from the temperature sensing module, and generates event data about the usage of the electrical equipment based on the current characteristic data stored in the storage module and the received current detection result and temperature sensing result, and transmits the event data to the routing device via the connection module.

[0011] The management server is connected to the communication network and includes a database, a storage unit, and a processing unit. The database stores user data related to at least one user in the field, as well as device data and historical usage data related to the electrical device. The storage unit stores a behavior feature recognition model for identifying multiple behavioral features of the at least one user in the use of the electrical device. The behavior feature recognition model is established based on multiple characteristic parameters associated with the at least one user, the electrical device, and the environment in which the electrical device is located, and utilizes a machine learning algorithm to analyze the user data and the historical usage data to summarize the behavioral features. The processing unit is electrically connected to the database and the storage unit.

[0012] The routing device transmits the received event data to the management server via the communication network. The processing unit of the management server uses the behavior feature recognition model stored in the storage unit to determine whether the received event data matches at least one of the behavior features, and sends an alert message to at least one user terminal associated with the at least one user if it is determined that the event data does not match any of the behavior features.

[0013] In the field monitoring system based on the usage of electrical appliances of the present invention, when the management server receives the event data from the routing device, the processing unit further performs the following operations: additionally stores the event data in the database and incorporates the event data into the historical usage data; determines whether the reference operating currents of the electrical equipment need to be adjusted based on the event data and the device data; and when it is determined that at least one of the reference operating currents needs to be adjusted, generates corresponding adjusted current characteristic data and transmits the adjusted current characteristic data to the routing device via the communication network. The routing device transmits the adjusted current characteristic information received from the management server to the connection module of the socket device. The processing module of the socket device updates the current characteristic data stored in the storage module with the adjusted current characteristic data received via the connection module.

[0014] In the field monitoring system based on appliance usage of the present invention, the socket device further includes an output module electrically connected to and controlled by the processing module. The processing module of the socket device further determines whether the electrical device is operating normally or abnormally based on the current detection result, the temperature sensing result, and the current characteristic data. If the electrical device is determined to be operating abnormally, the processing module causes the output module to generate a warning output indicating the abnormal state, or causes the socket module to interrupt the power supply to the electrical device.

[0015] In the field monitoring system based on the usage of electrical appliances of the present invention, the connection module of the socket device includes at least one of a connection interface for electrically connecting to the routing device and a wireless communication module that operates to communicate with the routing device or the communication network.

[0016] Another object of the present invention is to provide a socket device that can overcome at least one disadvantage of the prior art when used in the above-mentioned field monitoring system.

[0017] The present invention provides a socket device suitable for use in a field monitoring system. The field monitoring system is used to monitor electrical equipment used in a field and includes a management server. The socket device includes a socket module, a connection module, a storage module, a current detection module, a temperature sensing module, and a processing module.

[0018] The socket module is used to electrically connect the electrical device to a power grid and is operable to allow a power source from the power grid to be supplied to the electrical device, or to interrupt the power source. The connection module is adapted to be connected to the field monitoring system. The storage module stores current characteristic data relating to a plurality of reference operating currents of the electrical device in different operating modes. The current detection module is electrically connected to the socket module and is operable to continuously detect the current flowing through the electrical device to generate a current detection result. The temperature sensing module is operable to continuously sense the ambient temperature to generate a temperature sensing result. The processing module is electrically connected to the socket module, the connection module, the storage module, the current detection module, and the temperature sensing module, receives the current detection result from the current detection module and the temperature sensing result from the temperature sensing module, and generates event data relating to the usage of the electrical device based on the current characteristic data stored in the storage module and the received current detection result and temperature sensing result, and transmits the event data to the management server via the connection module.

[0019] In the socket device of the present invention, the field monitoring system also includes a routing device connected to the management server for communication, and the connection module includes at least one of a connection interface for electrically connecting to the routing device and a wireless communication module for communicating with the routing device or the management server.

[0020] The beneficial effect of the present invention is that: since the socket device will continuously send event data about the usage of electrical equipment to the management server, the management server determines whether the event data matches the behavioral characteristics to infer whether the behavior of users in the field using electrical equipment is normal, that is, whether the user's work and rest is normal, thereby achieving the purpose of field monitoring without disturbing the user at all while taking into account the user's privacy. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 2 is a block diagram of the architecture of a field monitoring system based on appliance usage according to an embodiment of the present invention; and

[0023] Figure 3 It is a flow chart illustrating how an embodiment of the present invention performs a household monitoring program. DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0025] Figure 1An example of an IoT system implemented in a household is illustrated. This IoT system may include multiple electrical appliances serving as nodes, such as televisions, rice cookers, electric kettles, and bidet toilet seats, a management cloud, and a gateway for establishing a communication connection between these nodes and the management cloud. The management cloud can collect information about the usage status of the electrical appliances from each node, calculate and analyze it, and then generate and store corresponding usage records for relevant users to download or query using a user terminal such as a mobile phone.

[0026] See Figure 2 , illustrating that the field monitoring system based on the use of electrical appliances according to an embodiment of the present invention can be easily implemented as follows Figure 1 The Internet of Things system shown is suitable for monitoring one or more electrical devices 200 (only one is shown in the figure) in a field such as a household, and can be regarded as a household monitoring system. However, in other embodiments, the field monitoring system can also be used as a factory monitoring system or a care institution monitoring system for monitoring one or more fields. In this embodiment, the household monitoring system may include, for example, a routing device 2, one or more socket devices 1 (only one is shown in the figure), and a management server 3. Please note that when the household monitoring system is implemented as an Internet of Things system, similar to Figure 1 In the IoT system shown in FIG. 1 , the management server 3 can be used as a management cloud, but is different from Figure 1 The IoT system shown is characterized in that each socket device 1 of this embodiment can serve as a node.

[0027] The router device 2 is adapted to be installed in the household and used to connect to a communication network 400 and support short-range wireless communication functions. For example, the router device 2 may include a wireless router (e.g., a WiFi router) or a gateway supporting WiFi and / or Bluetooth protocols (e.g., an NB-IoT Gateway dedicated to the Internet of Things) (not shown).

[0028] In this embodiment, each socket device 1 may include, for example, a socket module 11, a wireless communication module 15 serving as a connection module, a storage module 12, a current detection module 13, a temperature sensing module 14, an output module 16, and a processing module 17. The components of a socket device 1 will be described in further detail below.

[0029] The socket module 11 is used to electrically connect the corresponding electrical device 200 (hereinafter referred to as the electrical device) to an electrical grid 300 (for example, a household electrical grid). More specifically, the socket module 11 can be designed to have a pin portion (not shown) that can be plugged into a socket that is already connected to the electrical grid 300 (i.e., an existing socket in the household), and a slot portion (not shown) that allows the electrical plug of the electrical device to be inserted. In this way, the socket module 11 is connected to the electrical grid 300 through the existing socket in the household, but the present invention is not limited to this example. However, if the socket module 11 is directly electrically connected to the electrical grid 300, the above-mentioned pin portion can be omitted. The socket module 11 can be operated to allow a power supply from the electrical grid 300 to be supplied to the electrical device 200, or to interrupt the supply of the power supply. More specifically, the socket module 11 may, for example, include a controlled switch component (not shown), which can operate in a normal conductive state or a non-conductive state. In the conductive state, the power provided by the power grid 300 can be supplied to the electrical device 200 via the switch component, and in the non-conductive state, the power supply to the electrical device 200 is interrupted.

[0030] In this embodiment, the wireless communication module 15 operates to communicate with the router device 2, for example, using a short-range wireless communication method (e.g., WiFi protocol and / or Bluetooth protocol), or can directly connect to the communication network 400. Please note that in other embodiments, the socket device 1 can also include a connection interface (not shown) for electrically connecting to the router device 2. This connection interface can be used to replace the wireless communication module 15 and serve as the connection module, or this connection interface can coexist with the wireless communication module 15 to jointly constitute the connection module. Incidentally, when the wireless communication module 15 is connected to the communication network 400, the router device 2 can be omitted.

[0031] The storage module 12 stores, for example, a household identification code uniquely corresponding to the household, reference temperature data, current characteristic data of a plurality of reference operating currents of the (corresponding) electrical device 200 in different operating modes (see Figure 2). It should be noted in particular that the household identification code and the current characteristic data are obtained by executing a software application and inputting or downloading during the household's initial use or registration phase, and may include the category and model of the (corresponding) electrical device 200, the reference operating current (or reference current threshold) corresponding to each operating mode, the reference operating current range, etc. For example, if the (corresponding) electrical device 200 is a refrigerator, the reference operating current in the general power saving mode is approximately 30 mA, the reference operating current in the operating mode when the refrigerator door is open is approximately 130 mA, and the reference operating current in the operating mode when the compressor is running is approximately 1500 mA. Therefore, the reference operating current range is, for example, 30 to 1500 mA. For another example, if the (corresponding) electrical device 200 is a bidet toilet seat, the reference operating current in the standby mode is approximately between 60mA and 70mA, and the reference operating current in the cold water washing mode is approximately between 80mA and 90mA, so the reference operating current range is, for example, 60 to 90mA.

[0032] The current detection module 13 is electrically connected to the socket module 11 and operates to continuously detect the current flowing through the (corresponding) electrical device 200 to generate a current detection result.

[0033] The temperature sensing module 14 operates to continuously sense the ambient temperature (eg, the temperature inside and outside the socket device 1 , but not limited to this example) to generate a temperature sensing result.

[0034] The output module 16 can be controlled to generate an output such as an auditory or visual output. For example, the output module 16 can include an LED module and / or a buzzer (not shown), but is not limited to this example.

[0035] The processing module 17 is electrically connected to the socket module 11, the wireless communication module 15, the storage module 12, the current detection module 13, the temperature sensing module 14, and the output module 16 to receive the current detection result from the current detection module 13 and the temperature sensing result from the temperature sensing module 14. The functions and operations of the processing module 17 will be described in detail later.

[0036] The management server 3 is connected to the communication network 400 and may include, for example, a database 31, a storage unit 32, and a processing unit 33 electrically connected to the database 31 and the storage unit 32. For example, the management server 3 may be implemented as a single computer or a computer system composed of multiple computer hosts.

[0037] The database 31 stores user data of one or more users of the household, as well as device data and historical usage data of each electrical device 200. In other words, if the household monitoring system is used to monitor multiple electrical devices 200 in the household, the database 31 will store multiple device data and multiple historical usage data corresponding to the electrical devices 200. For example, the user data may include the gender and age of the user(s), the geographical area and / or location of the household, the household identification code, and one or more user terminals 500 ( Figure 2 Only one communication data (for example, the mobile phone number of the emergency contact of the user(s)) is shown; and for each electrical device 200, the device data may include data such as the electrical category, model, reference operating current range corresponding to different operating modes (in particular, the reference operating current range of the same electrical category and model collected in large quantities), and the historical usage data may include data such as relevant data for each use every day during a predetermined historical period (such as ambient temperature, usage time, operating mode and duration), daily accumulated usage time, etc.

[0038] Therefore, for each electrical device 200, the processing unit 33 can analyze the user data and the historical usage data based on multiple characteristic parameters associated with the user(s), the electrical device 200, and the environment in which the electrical device 200 is located (for example, the gender and age of each user, the geographical area of the household, the type and characteristics of the appliance, the usage time, the duration of usage, the cumulative usage time of the day, the ambient temperature, etc.) and using a machine learning algorithm (for example, a neural network regression algorithm) to summarize multiple behavioral characteristics of the household's usage behavior of the electrical device 200 and establish a behavioral characteristic recognition model for identifying these behavioral characteristics. The processing unit 33 stores the behavioral characteristic recognition model in the storage unit 32.

[0039] See Figure 2 and Figure 3 ,against Figure 2 The electrical device 200 shown in FIG. 2 shows how the household monitoring system executes a household monitoring program. The household monitoring program includes the following steps S301 to S310.

[0040] First, in step S301, within the socket device 1, the current detection module 13 continuously detects the current flowing through the electrical device 200 to generate a current detection result, and outputs the generated current detection result to the processing module 17. Simultaneously, the temperature sensing module 14 continuously senses the temperature of the environment surrounding the socket device 1 to generate a temperature detection result, and outputs the generated temperature detection result to the processing module 17. In this embodiment, the current detection result and the temperature detection result together constitute a detection result. Therefore, the processing module 17 of the socket device 1 continuously receives the current detection result and the temperature detection result from the current detection module 13 and the temperature detection module 14.

[0041] Then, in step S302, in the socket device 1, the processing module 17 generates event data related to the electrical device 200 and corresponding to the usage within each predetermined time period (which can be determined or changed according to actual circumstances) based on the current characteristic data stored in the storage module 12 and, for example, the current detection result and the temperature sensing result received within each predetermined time period (which can be determined or changed according to actual circumstances), and transmits the event data to the routing device 2 via the wireless communication module 15. For example, the event data may include relevant data such as the household identification code, the type and model of the electrical device 200, the start time, operating current and duration of each operating mode, the temperature inside and outside the socket device 1, etc., but is not limited to this example. Then, the routing device 2 transmits the received event data to the management server 3 via the communication network 400.

[0042] Afterwards, in step S303, in the management server 3, the processing unit 33 stores the event data in the database 31 when receiving the event data from the routing device 2, and in particular incorporates the event data into the historical usage data (corresponding to the electrical device 200).

[0043] Subsequently, in step S304, the processing unit 33 of the management server 3 uses the behavior feature recognition model stored in the storage unit 32 to determine whether the received event data matches at least one of the behavior features. If the determination result is positive, the process returns to step S303; otherwise, the process proceeds to step S305.

[0044] Please note that when the processing unit 33 of the management server 3 determines that the event data does not match any of the behavioral characteristics, this situation can be inferred that the user(s) of the household has exhibited abnormal behavior in the use of the electrical device that does not conform to the behavioral characteristics. For example, for the electrical device 200 being a refrigerator, if the event data on the same day indicates that neither the freezer door nor the refrigerator door of the refrigerator has been opened, the event data will be determined to not match any of the behavioral characteristics, and will be inferred to be abnormal behavior in the use of the refrigerator that does not conform to the behavioral characteristics.

[0045] In step S305, when the processing unit 33 of the management server 3 determines that the event data does not match the behavioral characteristics, it sends an alert message to the user terminal(s) 500 associated with the user based on the communication data stored in the database 31 to alert and notify relevant contacts (such as relatives, friends, or staff at a care facility) of the abnormal situation so that they can take appropriate action. The process then returns to step S303.

[0046] On the other hand, in step S306 following step S303, the processing unit 33 of the management server 3 determines whether the reference operating currents of the electrical device 200 need to be adjusted based on the received event data and the device data (corresponding to the electrical device 200) stored in the database 31. Please note that after the electrical device 200 has been used for a long time, the operating current of each operating mode will gradually increase due to the aging of its device components. Therefore, the processing unit 33 can compare the operating current included in the event data with the historical usage data stored in the database 31 to obtain an increasing trend, so as to determine whether the reference operating currents of the electrical device 200 need to be adjusted. Continuing with the above example, for an electrical device 200 such as a bidet toilet seat, the reference operating current in the standby mode is approximately between 60mA and 70mA, and the reference operating current in the cold water rinse mode is approximately between 80mA and 90mA, for example. However, after a long period of use, due to aging of the device components, the operating current in each operating mode will gradually increase. Specifically, the operating current in the standby mode may rise to 70mA to 80mA, and the operating current in the cold water rinse mode may rise to 85mA to 95mA. In this way, if the reference operating currents (such as the reference operating currents in the standby mode and the cold water rinse mode) contained in the current characteristic data stored in the storage module 12 of the socket device 1 are not adjusted, the processing module 17 may misjudge the operating mode.

[0047] Therefore, if the determination result of step S306 is affirmative, the process proceeds to step S307; otherwise, the process returns to step S303.

[0048] In step S307, the processing unit 33 on the management server 3 generates corresponding adjusted current characteristic data and transmits the adjusted current characteristic data to the routing device 2 via the communication network 400. The adjusted current characteristic data is used to update the reference operating current range contained in the device data stored in the database 31. The routing device 2 then transmits the adjusted current characteristic data received from the management server 3 to the processing module 17 via the wireless communication module 15 of the outlet device 1.

[0049] Then, in step S308, in the socket device 1, the processing module 17 updates the current characteristic data stored in the storage module 12 with the adjusted current characteristic data. Then, the process returns to step S303.

[0050] It is worth noting that due to the execution of steps S306 to S307, data optimization can be achieved, so that the socket device 1 can determine the operating mode of the electrical equipment more accurately and without error. In this way, due to the accurate operating mode, the management server 3 will also be relatively accurate in determining the match between event data and behavioral characteristics.

[0051] In addition, in step S309 following step S301, in the socket device 1, the processing module 17 further determines whether the electrical device 200 is operating in a normal state (or an abnormal state) based on the current detection result, the temperature sensing result, and the current characteristic data stored in the storage module 12. If the determination result is affirmative, the process returns to step S301; otherwise, the process proceeds to step S310. For example, if the operating current included in the current detection result exceeds the reference operating current range included in the current characteristic data, the processing module 17 determines that the operation of the electrical device 200 is in an abnormal state related to overcurrent. Alternatively, if the internal temperature included in the temperature detection result is higher than the temperature indicated by the reference temperature data stored in the storage module 12, the processing module 17 determines that the operation of the electrical device 200 is in an abnormal state related to overheating.

[0052] If the result of the determination in step S309 indicates that the electrical device 200 is not operating normally (i.e., is operating in an abnormal state), the processing module 17 controls the output module 15 to generate an alarm output (e.g., a buzzer sound or a flashing LED) indicating the abnormal state, or controls the socket module 11 to interrupt the power supply from the power grid 300 to the electrical device 200. For example, if the result of the determination in step S309 indicates that the electrical device 200 is operating in an abnormal state related to overcurrent, the processing module 17 controls the output module 15 to generate an alarm output such as a buzzer sound to remind the user to perform subsequent maintenance on the electrical device. If the result of the determination in step S309 indicates that the electrical device 200 is operating in an abnormal state related to overheating, the processing module 17 controls the socket module 11 to interrupt the electrical connection between the power grid 300 and the electrical device 200, thereby interrupting the power supply to the electrical device 200 to ensure the safe use of the electrical device 200.

[0053] As can be seen from the above description, since each socket device 1 continuously transmits event data regarding the usage of electrical devices 200 to the management server 3, the management server 3 determines whether the event data matches the behavioral characteristics to infer whether the user's behavior in the household or field using the relevant electrical device 200 is normal, that is, whether the user's daily routine is normal. This achieves the purpose of household monitoring without any interference to the user while also taking into account the user's privacy. In addition, through analysis of the event data, the management server 3 can optimize the current characteristic data used by the socket device 1 to determine the operating mode, ensuring more accurate usage behavior monitoring.

[0054] The above description is only a preferred embodiment of the present invention, but it is not intended to limit the scope of the present invention. Anyone familiar with this technology can make further improvements and changes on this basis without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims of this application.
