Description

Technical Field

[0001] This invention relates to the field of apartment power supply technology, and in particular to a switchable power supply device for apartment buildings. Background Technology

[0002] In apartment buildings, each resident has multiple power outlets installed, through which they connect various appliances. However, in many cases, even when no appliances are connected, the outlets remain exposed, which can become a cause of electric shock.

[0003] Previously, devices like timed sockets have been developed, and methods for users to manually set or control the socket via mobile applications have been proposed. However, these devices rely on direct user intervention, thus requiring constant user monitoring. Furthermore, the lack of intelligent judgment functions that reflect user habits or the usage patterns of surrounding appliances limits their actual accident prevention effectiveness.

[0004] Therefore, in apartment building environments, there is a need for a power supply device that can efficiently detect the usage status of each socket and take into account various factors such as user feedback, neighboring residents' usage patterns, and installation location, thereby automatically controlling its opening and closing, as well as an automatic shut-off controller that can control the device. Summary of the Invention

[0005] In apartment buildings, each resident has multiple power outlets installed, through which they connect various appliances. However, in many cases, even when no appliances are connected, the outlets remain exposed, which can become a cause of electric shock.

[0006] Previously, devices like timed sockets have been developed, and methods for users to manually set or control the socket via mobile applications have been proposed. However, these devices rely on direct user intervention, thus requiring constant user monitoring. Furthermore, the lack of intelligent judgment functions that reflect user habits or the usage patterns of surrounding appliances limits their actual accident prevention effectiveness.

[0007] Therefore, in apartment building environments, there is a need for a power supply device that can efficiently detect the usage status of each socket and take into account various factors such as user feedback, neighboring residents' usage patterns, and installation location, thereby automatically controlling its opening and closing, as well as an automatic shut-off controller that can control the device.

[0008] According to an embodiment of the present invention, an openable power supply device for apartment buildings includes: a body 10 with one side open and an interior space; a socket 20 housed in the interior space of the body 10 and having an insertion slot 21 for inserting a power plug; a fixing part 31 attached to the inner top surface of the socket 20 and having a vertically penetrating first receiving part 31a; a blocking membrane 33 movably inserted into the first receiving part 31a of the fixing part 31 and having a vertically penetrating second receiving part 33a; and a second receiving part 33a movably inserted into the blocking membrane 33 and having a front surface with a [missing information - likely a surface shape or shape]. The U-shaped guide groove 38 blocks the plug by causing the blocking membrane 33 to descend, and includes a counterweight 36 in the opening and closing member 30; combined with the socket 20, it forms a through hole 41 for the plug to pass through and a U-shaped guide groove 38 in the shape of a counterweight 36. The device includes: a cover 40 with a U-shaped guide groove 42 and extending through the front and back directions; a handle 50 attached to the guide groove 38 of the counterweight 36; a plug detection sensor for detecting whether a plug is inserted; a current sensor; an optical sensor for detecting whether the blocking membrane 33 blocks the socket; an actuator that allows the handle 50 to be moved to lower the blocking membrane 33 when the blocking membrane 33 does not block the socket; a communication circuit; and a processor. Furthermore, the processor confirms whether the plug is inserted via a plug detection sensor and periodically sends this information to the controller. At time t, it sends the plug insertion status to the controller. Based on the probability Pu(t) that the plug is not inserted at time t and remains in an uninserted state for a predetermined time interval Δt, which is greater than or equal to a critical probability value θ, the processor receives a cut-off command from the controller. In response to the cut-off command, it controls the actuator to lower the blocking membrane 33. After controlling the actuator, if the optical sensor confirms that the blocking membrane 33 has not blocked the socket for more than a predetermined critical time, it reports a first type of fault to the controller. If the current sensor confirms that no current is flowing and the plug detection sensor confirms that the plug is inserted into the socket, it reports a second type of fault to the controller. This configuration is as follows. sim(u,v) represents the similarity between the floor where the resident with power supply device u is located and the power supply device v and power supply device u installed on the same floor of the apartment building. The device characteristic vector Vu of the power supply device u has the form Vu=[P,A1,A2,…,Tu,Lu], where P is the number of residents in the household where the power supply device u is installed, A1, A2,… are the number of people in each age group, Tu is the average usage time of u, Lu is the coordinate of the installation location of u in the household, Ev(t) is the empirical value of the conditional probability that the plug of the power supply device v will remain in an uninserted state for a predetermined time interval Δt when the plug of the power supply device v is in an uninserted state at time t, and N is the set of power supply devices installed in the apartment building on the same floor as the household where the power supply device u is located.

[0009] According to different embodiments, the aforementioned critical probability value θ is dynamically adjusted based on the response rate Ru and acceptance rate Hu of the user of the power supply device u, and θ = θbase(1-αRuHu), where θbase is a predetermined basic critical probability value, α is a predetermined constant, the response rate Ru is the proportion of the user of the power supply device u responding to the cut-off confirmation message sent by the controller to the user equipment corresponding to the power supply device u when the probability Pu(t) is greater than or equal to the critical probability value θ, and the acceptance rate Hz is the proportion of the user of the power supply device u cutting off in response to the aforementioned cut-off confirmation message.

[0010] According to different embodiments, when the user's response rate Ru of the power supply device u is lower than Rth, the processor receives a cut-off command from the controller that has not sent the aforementioned cut-off confirmation message to the user equipment when the probability Pu(t) is greater than or equal to the critical probability value θ; when Ru is greater than or equal to Rth, and the probability P(t) is greater than or equal to the critical probability value θ, after sending the aforementioned cut-off confirmation message to the user equipment, it receives a cut-off command from the controller that has received a cut-off response from the user equipment. This configuration is as follows: M is the set of power supply devices installed in the household where power supply device u is located, and Rv is the response rate of the user in the household where power supply device v is installed.

[0011] According to different embodiments, after the processor responds to the cut-off command from the controller and controls the actuator to lower the blocking membrane (33), if the user manually restarts the power supply device within a specified time, it is configured to send a restart report to the controller, and according to the restart report, the critical probability value corresponding to the user will increase by an increment β.

[0012] According to different embodiments, if the processor sends a reopen report more than twice within a predetermined period, the increment β will increase.

[0013] The present invention achieves the following beneficial effects: An apartment building openable power supply device according to an embodiment of the present invention, through a structure capable of automatically closing the cover, can cut off unnecessary standby power and ensure safety. Furthermore, by detecting opening / closing failures using an optical sensor, physical faults can be automatically identified and reported, improving maintenance and management efficiency. Moreover, by using a dual detection structure employing both a plug detection sensor and a current sensor, sensor malfunctions can be detected, ensuring system reliability.

[0014] According to an embodiment of the present invention, an apartment building switchable power supply device can achieve customized user management by adjusting the judgment sensitivity based on the user's response tendency. For users with high response and acceptance rates, more proactive disconnection suggestions can be made, thereby achieving efficient accident prevention.

[0015] According to an embodiment of the present invention, the switchable power supply device for apartment buildings eliminates the need for repeatedly sending notifications to users with low response rates, thereby preventing unnecessary waste of communication resources, and can shorten the system response time through rapid cut-off decisions.

[0016] According to an embodiment of the present invention, an apartment building switchable power supply device can correct unnecessary cut-off judgments by reporting to the controller the fact that the user manually restarts the power supply immediately after the automatic cut-off, thereby realizing a more personalized control algorithm.

[0017] According to an embodiment of the present invention, an openable power supply device for apartment buildings can adapt to continuous changes in usage behavior by accumulating and reflecting repeated reopening behavior, thereby adjusting the judgment criteria. Attached Figure Description

[0028] Figure 1The connection relationships of an apartment building switchable power supply device and an automatic disconnect controller according to different embodiments of the present invention are illustrated. (Refer to...) Figure 1 Apartment building 1100 can contain multiple households 1000-1 and 1000-2, and each household 1000-1 and 1000-2 can contain multiple power supply units 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6. Each power supply unit 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6 can communicate with the automatic disconnect controller 200.

[0029] The automatic cut-off controller 200 may include a processor 210, a communication circuit 220, and a memory 230.

[0030] The processor 210 performs calculations based on data received via the communication circuit 220 and / or data stored in the memory 230, and can transmit at least a portion of the calculation results to other electronic devices via the communication circuit 220, or store them in the memory 230. In this specification, the description of the automatic disconnect controller 200 performing a certain operation includes the processor 210 referring to the memory 230 to perform calculations, or the processor 210 controlling other components of the automatic disconnect controller 200, such as the communication circuit 220, to enable the corresponding operation to be performed.

[0031] The communication circuit 220 can send information to or receive information from other electronic devices, and the types of communication supported by the communication circuit 220 are not limited.

[0032] The memory 230 can store various probabilities, critical probability values, device characteristic vectors of the multiple power supply devices 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6, as well as user equipment information corresponding to the multiple power supply devices 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6, which will be described later.

[0033] Figure 2 This is a block diagram of the electrical components of a switchable power supply device for apartment buildings according to different embodiments of the present invention. (Refer to...) Figure 2 The power supply device 100 may include a processor 110, a communication circuit 120, and a memory 130.

[0034] The processor 110 performs calculations based on data received via the communication circuit 120 and / or data stored in the memory 130, and can transmit at least a portion of the calculation results to other electronic devices via the communication circuit 120, or store them in the memory 130. In this specification, the description of the power supply device 100 performing an operation includes the processor 110 referring to the memory 130 to perform calculations, or the processor 110 controlling other components of the power supply device 100, such as the communication circuit 120, to enable the corresponding operation to be performed.

[0035] The communication circuit 120 can send information to or receive information from other electronic devices, and the types of communication supported by the communication circuit 120 are not limited.

[0036] The memory 130 can store information about the automatic cut-off controller 200 necessary for communication with it. The memory 130 can store detection values ​​and time points from the plug detection sensor 140, current sensor 150, and optical sensor 160. The memory 130 can store control records of the actuator 170.

[0037] The power supply device 100 may include a plug detection sensor 140, a current sensor 150, an optical sensor 160, and an actuator 170. The plug detection sensor 140 can determine whether a plug is inserted. When the power supply device 100 includes multiple sockets, the plug detection sensor 140 can determine that the plug is inserted as long as a plug is inserted into any of the multiple sockets. For example, the plug detection sensor 140 may be a microswitch mounted around the socket; when the plug is inserted, the switch is pressed and closed, thereby identifying that the plug is inserted. As another example, the plug detection sensor 140 may include an infrared transmitter-receiver pair mounted on the socket; when the infrared beam is blocked by the plug, the plug is identified as inserted.

[0038] The current sensor 150 can determine whether current flows through the plug. For example, the current sensor 150 can be a clamp current sensor or a Hall sensor.

[0039] Optical sensor 160 can detect whether the blocking film 33, described later, is blocking the socket. For example, optical sensor 160 can be an illuminance sensor; when the blocking film 33 blocks the socket, the illuminance inside the power supply device 100 decreases, so optical sensor 160 can determine that the blocking film 33 is blocking the socket. Alternatively, optical sensor 160 can be mounted on socket 20 and can emit light from the socket to the outside. When the blocking film 33 blocks the socket, the emitted light is reflected by the blocking film 33; when the blocking film 33 does not block the socket, the emitted light is reflected by the cover 40. Therefore, optical sensor 160 can determine whether the blocking film 33 is blocking the socket based on the reflected light.

[0040] The actuator 170 can be configured to move the handle 50 to lower the blocking membrane 33 when the blocking membrane 33 does not block the socket.

[0041] Figure 3 and Figure 4 The mechanical components of a switchable power supply device for apartment buildings according to different embodiments of the present invention are shown. For example... Figure 3 and Figure 4 As shown, the apartment building switchable power supply device 100 according to the present invention consists of a body 10, a socket 20, a switchable component 30, and a cover 40.

[0042] One side of the main body 10 is open, and the interior has a space to accommodate or remove the socket 20.

[0043] The socket 20 is a regular socket 20, which is housed in the internal space of the main body 10. One side is open, and the interior has a blank space for installing the opening and closing component 30, and a power plug insertion slot 21 for inserting the power plug pins. When the power plug pins are inserted, power is supplied.

[0044] The opening and closing component 30 described above consists of a fixing part 31, a blocking membrane 33, and a counterweight 36.

[0045] The fixing part 31 is formed into a flat rectangular shape and is attached to the inner top surface of the socket 20. It has a first receiving part 31a that runs vertically through the socket. A first locking flange 32 for preventing the lower part of the blocking membrane 33 from detaching is formed on the inner bottom surface of the first receiving part 31a.

[0046] The blocking membrane 33 is formed into a flat rectangular shape and is made to a size that allows it to move freely in the vertical direction along the first receiving portion 31a when it is inserted into the first receiving portion 31a of the fixing portion 31.

[0047] The upper two ends of the blocking membrane 33 have first placement portions 34, which extend horizontally outward. Therefore, when the blocking membrane 33 is inserted into the first receiving portion 31a from the upper side of the fixing portion 31, the blocking membrane 33 will descend along the first receiving portion 31a. When the first placement portion 34 engages with the first locking flange 32 of the fixing portion 31, the lower part of the first placement portion 34 will stop in a form that exposes to the lower side of the fixing portion 31.

[0048] In addition, the blocking membrane 33 has a second receiving portion 33a that extends vertically, and a second locking flange 35 is formed on the inner bottom surface of the second receiving portion 33a to prevent the lower part of the counterweight 36 from disengaging. One or more blocking membranes 33 may be used.

[0049] The counterweight 36 is formed into a flat rectangular shape and is made to be able to move freely in the vertical direction along the second receiving portion 33a when it is inserted into the second receiving portion 33a of the blocking membrane 33.

[0050] The upper ends of the weight 36 are provided with second mounting portions 37, which extend horizontally outward. Therefore, when the weight 36 is inserted into the second receiving portion 33a of the blocking membrane 33 from the upper side, the weight 36 will descend along the second receiving portion 33a. When the second mounting portion 37 engages with the second locking flange 35 of the blocking membrane 33, the lower part of the second mounting portion 37 will stop in a form that exposes to the lower side of the blocking membrane 33.

[0051] In addition, a cross-section roughly shaped is formed on the front of the hammer 36. The guide groove 38 is shaped like a letter and is used to guide the movement of the handle 50.

[0052] The cover 40 is attached to the front of the socket 20 to prevent water, foreign objects, etc. from flowing into the internal space of the socket 20. It has a through hole 41 for the plug to pass through, so that the plug can be inserted into the socket 20. The cover 40 also has a cross-section that is approximately [insert cross-section here]. The guide hole 42 is shaped like a character and together with the guide groove 38 of the counterweight 36 is used to guide the movement of the handle 50, and the guide hole 42 is through the front and back.

[0053] One side of the handle 50 protrudes outside the cover 40, while the other side passes through the guide hole 42 of the cover 40 and is inserted into the guide groove 38 of the counterweight 36. The inlet side of the socket 20 is opened or closed by controlling the opening and closing component 30.

[0054] Figure 5 The operation performed in the switchable power supply device and automatic cut-off controller for apartment buildings according to different embodiments of the present invention is illustrated.

[0055] In operation 510, the processor 210 of the automatic disconnect controller 200, for any one of the multiple power supply devices v installed in the apartment building, can determine the conditional probability Ev(t) that the plug in the socket of power supply device v will remain unplugged for a predetermined time interval Δt when the plug is not inserted at time t. The processor 210 can calculate the conditional probability for all power supply devices installed in the apartment building in operation 510.

[0056] Ev(t) can be defined as in mathematical formula 1.

[0057] Ev(t) = P(not inserted continuously during time Δt | in a non-inserted state at time t) (Formula 1)

[0058] To perform operation 510, processor 210 can periodically receive information about whether a plug is inserted from the plug detection sensor 140 built into the power supply device v, and store this information in the form of a log. For example, the log can contain data such as "t = 10:00 AM Inserted", "t = 10:01 AM Inserted", "t = 10:02 AM Not Inserted". The period for recording whether a plug is inserted can be varied. Processor 210 can calculate Ev(t) as the proportion of the number of data points in the log that are determined to be not inserted, and the number of data points that remain in an uninserted state for a period of time after the corresponding time point. For example, if there are 100 data points in the log that are not inserted at t = 10:00 AM, and 10 of them remain in an uninserted state for the next 10 minutes, then the Ev(t) value for t = 10:00 AM is 0.1.

[0059] In operation 520, the processor 110 of the power supply device 100 can confirm whether a plug is inserted at time t via the plug detection sensor 140, and can send this information to the processor 210 of the automatic disconnect controller 200. The processor 210 of the automatic disconnect controller 200 can confirm whether a plug is inserted into the socket of the power supply device v at time t.

[0060] In operation 530, when the plug in the socket of the power supply device u is not inserted at time t, the processor 210 of the automatic cut-off controller 200 can determine the probability Pu(t) that the plug remains in the uninserted state for a predetermined time interval Δt, and can determine that the determined probability Pu(t) is greater than or equal to the critical probability value θ.

[0061] Pu(t) can be defined as in mathematical formula 2.

[0062]

[0063] In mathematical formula 2, sim(u,v) is the similarity between power supply device v and power supply device u installed on the same floor as the apartment where power supply device u is located. N is the set of power supply devices installed on the same floor as the apartment where power supply device u is located. The similarity between power supply device v and power supply device u can be defined as in mathematical formula 3.

[0064]

[0065] The device characteristic vector Vu of the power supply device u has the form Vu = [P, A1, A2, ..., Tu, Lu], where P is the number of residents in the household where the power supply device u is installed, and A1, A2, ... are the number of people in each age group. For example, when the age groups are defined as under 10 years old, 10 years and older but under 20 years old, 20 years and older but under 30 years old, 30 years and older but under 40 years old, 40 years and older but under 50 years old, 50 years and older but under 60 years old, 60 years and older but under 70 years old, 70 years and older but under 80 years old, and over 80 years old, it can be represented as [A1, A2, A3, A4, A5, A6, A7, A8, A9] = [0, 0, 0, 1, 1, 2, 0, 0, 0]. Tu is the average usage time of u, and Lu is the coordinate of the installation location of u in the household. The processor 210 can refer to the log of u and determine the average usage time as the average duration from when the plug is inserted once to when it is unplugged.

[0066] The critical probability value θ can be initially defined as a predetermined basic critical probability value θbase. Depending on the implementation, the critical probability value θ can be dynamically adjusted based on the user's response rate Ru and acceptance rate Hu of the power supply device u. The critical probability value θ can be adjusted as shown in mathematical formula 4.

[0067] θ=θbase(1-αRuHu) (Formula 4)

[0068] α is a predetermined constant, the response rate Ru is the proportion of the user's response to the cutoff confirmation message for power supply device u, which will be described later, and the acceptance rate Hu is the proportion of the user's cutoff response to the cutoff confirmation message for power supply device u, which will be described later.

[0069] Based on the fact that the probability Pu(t) confirmed in operation 530 is greater than or equal to the critical probability value θ, processor 210 may send a cut-off confirmation message to user equipment 300 in operation 540 to confirm whether the power supply device u has been cut off.

[0070] In operation 550, processor 210 can receive a cut-off response from user equipment 300. Based on receiving the cut-off response, processor 210 can send a cut-off command to power supply device u in operation 560. Processor 110 of power supply device 100 can receive the cut-off command from processor 210 based on the probability Pu(t) that the plug is in an uninserted state at time t and remains in an uninserted state for a predetermined time interval Δt is greater than or equal to a critical probability value θ.

[0071] In operation 570, the processor 110 of the power supply device 100 can respond to a cut-off command by controlling the actuator 170 to lower the blocking membrane 33. When the actuator 170 lowers the blocking membrane 33, the socket of the power supply device 100 may be cut off.

[0072] According to different embodiments, after executing operation 570, the processor 110 of the power supply device 100 can confirm via the optical sensor 160 that the blocking membrane 33 has not disconnected the socket after a predetermined critical time has elapsed. In this case, the processor 110 of the power supply device 100 can report a first type of fault to the processor 210 of the automatic disconnection controller 200. When the first type of fault is reported, the processor 210 of the automatic disconnection controller 200 can send a message to the user equipment 300 corresponding to the power supply device 100, informing that at least one of the actuator, the blocking membrane, or the optical sensor has failed.

[0073] According to different embodiments, the processor 110 of the power supply device 100 can at any time confirm whether current is flowing as detected by the current sensor and whether a plug is inserted into a socket as detected by the plug detection sensor. When it is confirmed that no current is flowing as detected by the current sensor and the plug detection sensor detects that a plug is inserted into a socket, the processor 110 of the power supply device 100 can report a second type of fault to the processor 210 of the automatic disconnect controller 200. When the second type of fault is reported, the processor 210 of the automatic disconnect controller 200 can send a message to the user equipment 300 corresponding to the power supply device 100, informing that at least one of the current sensor and the plug detection sensor has failed.

[0074] According to different implementations Figure 5Operations 540 and 550 can be omitted in certain situations. When the processor 210 of the automatic disconnection controller 200 detects that the user's response rate Ru of the power supply device u is lower than Rth, and the probability Pu(t) is greater than or equal to the critical probability value θ, it can directly send a disconnection command to the power supply device u instead of sending a disconnection confirmation message to the user equipment corresponding to the power supply device u. Conversely, when the processor 210 of the automatic disconnection controller 200 detects that Ru is greater than or equal to Rth, and the probability Pu(t) is greater than or equal to the critical probability value θ, it can send a disconnection confirmation message to the user equipment corresponding to the power supply device u, and then send a disconnection command to the power supply device u after receiving the disconnection response from the user. Here, Rth can be defined as in mathematical formula 5.

[0075]

[0076] In mathematical formula 5, M is the set of power supply devices installed in the household where power supply device u is located, and Rv is the response rate of the user in the household where power supply device v is installed.

[0077] In other words, when the processor 110 of the power supply device u100 detects that the user's response rate Ru of the power supply device u is lower than Rth, and when the probability Pu(t) is greater than or equal to the critical probability value θ, it will receive a cut-off command from the automatic cut-off controller 200 that has not sent a cut-off confirmation message to the user equipment; when Ru is greater than or equal to Rth, and when the probability P(t) is greater than or equal to the critical probability value θ, it will receive a cut-off command from the automatic cut-off controller 200 that has received a cut-off response from the user equipment after sending a cut-off confirmation message to the user equipment.

[0078] According to different embodiments, after the processor 110 of the power supply device u100 controls the actuator to lower the blocking membrane 33 in response to a cut-off command from the automatic cut-off controller 200, if the user manually reopens the power supply device within a specified time, it can send a reopening report to the processor 210 of the automatic cut-off controller 200. In other words, after the processor 210 of the automatic cut-off controller 200 sends a cut-off command to the power supply device u, and after the actuator of the power supply device u is controlled to lower the blocking membrane of the power supply device u, if the user of the power supply device u manually reopens the power supply device within a specified time, it can receive a reopening report from the power supply device u. The processor 210 of the automatic cut-off controller 200 can increase the critical probability value corresponding to the user of the power supply device u by an increment β in response to the reopening report. The initial value of the increment β can be a predetermined value. According to different embodiments, when the processor 210 of the automatic cut-off controller 200 receives more than two reopening reports within a predetermined period, the increment β can be increased. That is, the critical probability value can be increased by a larger margin. The magnitude of the increase in increment β can have a predetermined value.

However, those skilled in the art should understand that the present invention can be implemented in other specific forms without changing its technical concept or essential features. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
