Description

Technical Field

[0001] This invention relates to the field of electrical control technology, and in particular to an automatic power-off controller for an apartment building electrical system. Background Technology

[0002] In apartment buildings, each unit is equipped with multiple power outlets, which residents use to connect various electrical appliances. However, in many cases, even when no appliances are connected, the outlets remain exposed, which can be a cause of electric shock.

[0003] Previously, devices such as timed sockets have been developed, and methods for users to manually set or control the sockets via mobile applications have been proposed. However, these devices rely on direct user intervention, thus requiring continuous user monitoring. Furthermore, the lack of intelligent judgment functions reflecting user habits or surrounding appliance usage patterns 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 automatically control the switch by taking into account various factors such as user reactions, neighboring residents' usage patterns, and installation location, as well as an automatic power-off controller that can control the device. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic power-off controller for controlling switchable power supply devices used in apartment buildings, which can realize automatic power-off and fault detection.

[0006] Another objective of this invention is to provide an automatic power-off controller for an apartment building electrical system that can reflect user behavior patterns such as manual restart behavior, response rate, and acceptance rate, thereby achieving more personalized accident prevention.

[0007] An apartment electrical automatic disconnection controller according to an embodiment of the present invention includes a communication circuit, a memory, and a processor, wherein the processor: periodically receives information from a plurality of power supply devices installed in the apartment regarding whether a plug is inserted in the socket of the power supply device; for any one of the plurality of power supply devices v, when no plug is inserted in the socket of power supply device v at time t, confirms the conditional probability Ev(t) that the plug will remain uninserted for a predetermined time interval Δt; confirms whether a plug is inserted in the socket of power supply device v at time t; when no plug is inserted in the socket of power supply device u at time t, confirms the probability Pu(t) that the plug will remain uninserted for a predetermined time interval Δt; and sends a disconnection confirmation message to the user equipment corresponding to power supply device u based on the condition that Pu(t) is greater than or equal to a critical probability value θ.

[0008] Based on the disconnection response received from the user equipment, a disconnection command is sent to the power supply equipment u, thereby causing the power supply equipment u to lower its internal disconnection baffle to disconnect the socket of the power supply equipment u; wherein sim(u,v) is the similarity between the household where power supply equipment u is installed and the apartment where power supply equipment v is installed on the same floor; The equipment characteristic vector Vu of power supply equipment u has the form Vu=[P,A1,A2,…,Tu,Lu], where P is the number of residents in the household where power supply equipment 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 location coordinates of u installed in the household, and N is the set of power supply equipment installed in the apartment on the same floor as the household where power supply equipment u is installed.

[0009] According to various embodiments, the processor is configured to dynamically adjust the critical probability value θ based on the response rate Ru and acceptance rate Hu of the user of the power supply device u, where θ = θbase(1-αRuHu), 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 confirmation message of whether to cut off, and the acceptance rate Hz is the proportion of the user of the power supply device u responding to the confirmation message of whether to cut off.

[0010] According to various embodiments, the processor is configured to: when the response rate Ru of the user of the power supply device u is lower than Rth, if the probability Pu(t) is greater than or equal to the critical probability value θ, then not send the confirmation message for whether to disconnect to the user equipment corresponding to the power supply device u, but instead send a disconnect command to the power supply device u; when Ru is greater than or equal to Rth, if the probability Pu(t) is greater than or equal to the critical probability value θ, then send the confirmation message for whether to disconnect to the user equipment corresponding to the power supply device u, and then, upon receiving a disconnect response from the user, send a disconnect command to the power supply device u; here is... M is the set of power supply devices installed in the household where power supply device u is installed, and Rv is the response rate of the users in the household where power supply device v is installed.

[0011] According to various embodiments, the processor is configured to: after sending a cut-off command to the power supply device u, and after controlling the actuator of the power supply device u to lower the cut-off baffle of the power supply device u, if the user of the power supply device u manually reopens the power supply device within a predetermined time, receive a reopening report from the power supply device u, and in response to the reopening report, increase the critical probability value corresponding to the user of the power supply device u by an increment β.

[0012] According to various embodiments, the processor is configured to increase the increment β if more than two reopening reports are received within a predetermined time period.

[0013] The present invention achieves the following beneficial effects: An apartment building automatic electrical disconnect controller according to an embodiment of the present invention can achieve customized management by adjusting the judgment sensitivity based on the user's response tendencies. For users with high response and acceptance rates, more proactive disconnection suggestions can be made, thereby achieving efficient accident prevention.

[0014] According to an embodiment of the present invention, an automatic electrical disconnect controller for apartment buildings can prevent unnecessary waste of communication resources by omitting repeated notifications for users with low response rates, and shorten system response time by making disconnection decisions quickly.

[0015] According to an embodiment of the present invention, an automatic electrical disconnection controller for apartment buildings corrects unnecessary disconnection judgments based on the fact that users manually reconnect the electrical circuits immediately after automatic disconnection, thereby enabling a more personalized control algorithm.

[0016] According to one embodiment of the present invention, an automatic electrical disconnection controller for apartment buildings can adapt to continuous changes in usage behavior by accumulating and reflecting repeated restart behaviors, thereby adjusting the judgment criteria.

[0027] Figure 1 The connection relationships of a switchable power supply device and an automatic disconnect controller for apartment buildings according to various 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 devices 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6. Each power supply device 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6 can communicate with the automatic disconnect controller 200.

[0028] The automatic cut-off controller 200 may include a processor 210, a communication circuit 220, and a memory 230.

[0029] 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 an operation means that the processor 210 refers to the memory 230 to perform calculations, or that the processor 210 controls other components of the automatic disconnect controller 200, such as the communication circuit 220, to enable the corresponding operation to be performed.

[0030] 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.

[0031] The memory 230 can store the 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, which will be described later, and user equipment information corresponding to the multiple power supply devices 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6.

[0032] Figure 2 This is a block diagram of the electrical components of a switchable power supply device for apartment buildings according to various 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.

[0033] 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 means that the processor 110 refers to the memory 130 to perform calculations, or that the processor 110 controls other components of the power supply device 100, such as the communication circuit 120, to enable the corresponding operation to be performed.

[0034] 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.

[0035] The memory 130 can store information about the automatic cut-off controller 200 necessary for communication with it. The memory 130 can store the sensing values ​​and timing information of the plug detection sensor 140, the current sensor 150, and the optical sensor 160. The memory 130 can store control records of the actuator 170.

[0036] 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 if a plug is inserted into any one of the 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. Alternatively, 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, it can identify that the plug is inserted.

[0037] The current sensor 150 can determine whether current is flowing through the plug. For example, the current sensor 150 can be a clamp current sensor or a Hall sensor.

[0038] Optical sensor 160 can detect whether the cut-off baffle 33, described later, has cut off the socket. For example, optical sensor 160 can be an illuminance sensor; when the cut-off baffle 33 cuts off the socket, the illuminance inside the power supply unit 100 decreases, so optical sensor 160 can determine that the cut-off baffle 33 is cutting off the socket. For example, optical sensor 160 can be mounted on socket 20 and can emit light from the socket to the outside. When the cut-off baffle 33 cuts off the socket, the emitted light is reflected by the cut-off baffle 33; when the cut-off baffle 33 is not cutting off the socket, the emitted light is reflected by the cover 40. Therefore, optical sensor 160 can determine whether the cut-off baffle 33 is cutting off the socket based on the reflected light.

[0039] The actuator 170 can be configured to move the handle 50 to lower the cut-off baffle 33 when the cut-off baffle 33 is not cutting off the socket.

[0040] Figure 3 and Figure 4 The mechanical components of a switchable power supply device for apartment buildings according to various embodiments of the present invention are shown. For example... Figure 3 and Figure 4 As shown, the switchable power supply device 100 for apartment buildings according to the present invention consists of a body 10, a socket 20, a switch component 30, and a cover 40.

[0041] One side of the body 10 is open and has a space formed inside so that the socket 20 can be accommodated or pulled out.

[0042] 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 a blank space is formed inside for installing the switch component 30. A power plug insertion slot 21 is formed for inserting the power plug pins of the plug. Power is supplied when the power plug pins of the plug are inserted.

[0043] Here, the switch component 30 consists of a fixing part 31, a cutting baffle 33, and a counterweight 36.

[0044] The fixing part 31 is formed into a flat rectangular shape and is attached to the inner ceiling 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 cutting baffle 33 from disengaging is formed on the inner bottom surface of the first receiving part 31a.

[0045] The cutting baffle 33 is formed as a flat rectangular plate and is made to be able 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.

[0046] The cutting baffle 33 has first mounting portions 34 formed at both ends of its upper portion, which extend horizontally outward. Therefore, when the cutting baffle 33 is inserted into the first receiving portion 31a from the upper side of the fixing portion 31, the cutting baffle 33 will descend along the first receiving portion 31a. When the first mounting portion 34 engages with the first locking flange 32 of the fixing portion 31, the lower part of the first mounting portion 34 will stop in a form that exposes to the lower side of the fixing portion 31.

[0047] In addition, the cutting baffle 33 has a second receiving portion 33a that extends vertically, and a second locking flange 35 for preventing the lower part of the counterweight 36 from disengaging is further formed on the inner bottom surface of the second receiving portion 33a. One or more of the cutting baffle 33 may be used.

[0048] The counterweight 36 is formed as a flat rectangular plate 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 cutting baffle 33.

[0049] The counterweight 36 has second mounting portions 37 formed at both ends of its upper part, which extend horizontally outward. Therefore, when the counterweight 36 is inserted into the second receiving portion 33a from the upper side of the cutting baffle 33, the counterweight 36 will descend along the second receiving portion 33a. When the second mounting portion 37 engages with the second locking flange 35 of the cutting baffle 33, the lower part of the second mounting portion 37 will stop in a form that exposes to the lower side of the cutting baffle 33.

[0050] Furthermore, a cross-section approximately shaped is formed on the front of the counterweight 36. The guide rail groove 38 is shaped like a letter and is used to guide the movement of the handle 50.

[0051] 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. The through hole 41 extends in the front-to-back direction so that the plug can be easily inserted into the socket 20. The cover 40 has a cross-section that is approximately [insert cross-section here]. A U-shaped guide hole 42, together with the guide groove 38 of the counterweight 36, is used to guide the movement of the handle 50. The guide hole 42 is through in the front-to-back direction.

[0052] One side of the handle 50 protrudes outside the cover 40, and the other side passes through the guide rail hole 42 of the cover 40 and is inserted into the guide rail groove 38 of the counterweight 36. The inlet side of the socket 20 is opened or closed by controlling the switch component 30.

[0053] Figure 5 The operation performed in a switchable power supply device and automatic disconnect controller for apartment buildings according to various embodiments of the present invention is illustrated.

[0054] 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 will remain unplugged for a predetermined time interval Δt when the plug is not inserted in the socket of power supply device v at time t. The processor 210 can calculate the conditional probability for all power supply devices installed in the apartment building in operation 510.

[0055] Ev(t) can be defined as in mathematical formula 1.

[0056]

Mathematical Formula 1

[0057] Ev(t) = P remains uninserted for a period of time Δt | is in an uninserted state at time t.

[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 it in the form of a log. For example, the log can contain data such as "inserted at t = 10:00 AM, inserted at t = 10:01 AM, not inserted at t = 10:02 AM". 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 the not-inserted state for a period of Δi after that 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 the not-inserted 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 unit 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 unit v at time t.

[0060] In operation 530, when the socket of the power supply device u is in an unplugged state at time t, the processor 210 of the automatic cut-off controller 200 can determine the probability Pu(t) that the plug will remain unplugged for a predetermined time interval Δt, and can determine whether 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]

Mathematical Formula 2

[0063]

[0064] In mathematical formula 2, sim(u,v) is the similarity between the household where power supply device u is installed and power supply device v and power supply device u located on the same floor of the apartment building. N is the set of power supply devices installed in the apartment building located on the same floor as the household where power supply device u is installed. The similarity between power supply device v and power supply device u can be defined as in mathematical formula 3.

[0065]

Mathematical Formula 3

[0066]

[0067] 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 households 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].

[0068] Tu is the average usage time of u, and Lu is the coordinate of the location where u is installed in the household. The processor 210 can refer to the log of u to determine the average usage time as the average duration from when the plug is inserted once until it is unplugged.

[0069] The critical probability value θ can be initially defined as a predetermined basic critical probability value θbase. According to various embodiments, 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.

[0070]

Mathematical Formula 4

[0071] θ = θbase(1-αRuHu)

[0072] α is a predetermined constant, the response rate Ru is the proportion of users of power supply device u who respond to the confirmation message of whether or not the power supply is cut off (described later), and the acceptance rate Hu is the proportion of users of power supply device u who respond to the confirmation message of whether or not the power supply is cut off (described later).

[0073] 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 disconnection confirmation message to user equipment 300 in operation 540 to confirm whether the power supply device u has been disconnected.

[0074] 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 a 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.

[0075] In operation 570, the processor 110 of the power supply unit 100 can control the actuator 170 to lower the cut-off baffle 33 in response to a cut-off command. When the actuator 170 lowers the cut-off baffle 33, the socket of the power supply unit 100 can be cut off.

[0076] According to various embodiments, after executing operation 570, the processor 110 of the power supply device 100 can confirm, via the optical sensor 160, that the cut-off baffle 33 has not cut off the socket beyond a predetermined critical time. In this case, the processor 110 of the power supply device 100 can report a first-type fault to the processor 210 of the automatic cut-off controller 200. Upon receiving the first-type fault report, the processor 210 of the automatic cut-off 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 cut-off baffle, or the optical sensor has failed.

[0077] According to various 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 the socket as detected by the plug detection sensor. When the current sensor confirms that no current is flowing and the plug detection sensor confirms that the plug is inserted into the 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. Upon receiving the second type of fault report, 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.

[0078] According to various embodiments, Figure 5 Operations 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, if 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, if the probability Rth is greater than or equal to the critical probability value θ, it can first 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 upon receiving a disconnection response from the user. Here, Rth can be defined as in mathematical formula 5.

[0079] [Mathematical Formula 5]

[0081] In mathematical formula 5, M is the set of power supply devices installed in the households where power supply device u is installed, and Rv is the response rate of the users in the households where power supply device v is installed.

[0082] In other words, when the processor 110 of the power supply device u100 detects that the response rate Ru of the user of the power supply device u is lower than Rth, if the probability Rth is greater than or equal to the critical probability value θ, then it will receive a cut-off command from the automatic cut-off controller 200, and at this time it will not send a confirmation message of whether to cut off to the user equipment; when Ru is greater than or equal to Rth, if the probability P(t) is greater than or equal to the critical probability value θ, then after sending a confirmation message of whether to cut off to the user equipment, and upon receiving a cut-off response from the user equipment, it can receive a cut-off command from the automatic cut-off controller 200.

[0083] According to various embodiments, after the processor 110 of the power supply device u100 controls the actuator to lower the cut-off baffle 33 in response to a cut-off command issued by the automatic cut-off controller 200, if the user manually reopens the power supply device within a predetermined 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 controls the actuator of the power supply device u to lower the cut-off baffle, if the user of the power supply device u manually reopens the power supply device within a predetermined time, it can receive a reopening report from the power supply device u. In response to this reopening report, 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. The initial value of the increment β can be a predetermined value. According to various embodiments, if the processor 210 of the automatic cut-off controller 200 receives more than two reopening reports within a predetermined time period, it can increase the increment β. 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.

[0084] The embodiments of the present invention have been described above with reference to the accompanying drawings. 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.
