Summary of the Invention

[0015] Establish power control rules according to the three safety levels of electrical appliances and the four working states of the intelligent socket strip, namely: for the state where the bed is unoccupied and the device is offline, immediately perform a power-off operation; for the state where the bed is unoccupied and the device is online, perform a power-off operation after a set time delay; for the state where the bed is occupied and the device is offline, there is no usage restriction for low-risk electrical appliances, medium-risk electrical appliances are powered off at a fixed time, and high-risk electrical appliances are restricted from use; for the state where the bed is occupied and the device is online, there is no usage restriction for low-risk and medium-risk electrical appliances, and high-risk electrical appliances need to be authorized by the user on the terminal device before use.

[0016] Preferably, a user's electricity consumption habit model is established, including: collecting the user's electricity consumption information over a period of time as historical normal data, processing the collected current data and power data to obtain the corresponding current values and operating powers when the user uses different electrical appliances and different modes of the electrical appliances, respectively counting the number of times the user uses the electrical appliances during the data collection period for different operating powers, and recording the energization duration of each time for each operating power; calculating and obtaining the average energization duration corresponding to different operating powers when the user uses the electrical appliances, and correlating and mapping different operating powers with the corresponding average energization durations to generate the user's electricity consumption habit model; periodically collecting and recording the user's electricity consumption information and periodically updating the user's electricity consumption habit model.

[0018] Preferably, the detection information data at the current sampling moment is obtained, and the abnormal risk value is calculated, including: collecting in real time the current data and power data of each AC socket module, as well as the temperature data detected by the temperature detection modules in the smart socket main body and the smart socket branch body respectively, and obtaining the abnormal trigger signals of the smoke detection module and the AC leakage current detection module;

[0019] Through the collected current data, the short-circuit risk value I at the t-th sampling moment is obtained Y,t : When I t,n ≥k×I t-1,n , when any AC socket module has a short-circuit condition, I Y,t =1; when I t,n <k×I t-1,n , when all AC socket modules have no short-circuit condition, I Y,t =0; I t,n represents the output current value of the n-th AC socket module at the t-th sampling moment, I t-1,n represents the output current value of the n-th AC socket module at the (t - 1)-th sampling moment, k represents the short-circuit threshold parameter, when t = 1, by default I Y,t =0, and the value range of n is from 1 to N;

[0024] Obtain the smoke risk value W at the t-th sampling moment by detecting the abnormal trigger signal of the smoke detection module Y,t : When an abnormal trigger signal sent by any smoke detection module in the main body of the smart socket and the smart socket splitter is detected, W Y,t = 1, when no abnormal trigger signal is sent by the smoke detection modules in the smart socket, W Y,t = 0;

[0025] Combine the short - circuit risk value I Y,t , the leakage risk value D Y,t , the temperature risk value T Y,t , and the smoke risk value W Y,t with their corresponding weight values respectively, and calculate the abnormal risk value Y of the smart socket at the t-th sampling moment t , where the set weight values satisfy a + b + c + d = 1.5.

[0026] Preferably, determine the risk level according to the calculated abnormal risk value, including: when 0 < Y t < 0.2, the risk level is level zero; when 0.2 ≤ Y t < 0.4, the risk level is level one; when 0.4 ≤ Y t < 0.7, the risk level is level two; when 0.7 ≤ Y t < 1.5, the risk level is level three.

[0027] Preferably, in response to the determination result of the risk level, based on the power control rule, an abnormal alarm corresponding to the level is triggered, including when the risk level is level one, immediately cutting off the power output of the corresponding abnormal AC socket module, triggering the buzzer of the smart socket, and at the same time sending the abnormal information to the user's terminal device through the wireless communication module to remind the user to eliminate the hidden danger in time. When in the device offline state, the wireless communication module sends the abnormal information to the power supervision background of the dormitory building to remind the relevant management personnel to check in time; when the risk level is level two, immediately cut off the power output of the entire smart socket, trigger the buzzer of the smart socket, and at the same time send the abnormal information to the power supervision background of the dormitory building and the user's terminal device through the wireless communication module to remind the relevant management personnel and the user to eliminate the safety hazard in time; when the risk level is level three, immediately cut off the power output of the entire smart socket, the wireless communication module urgently sends the abnormal information to the power supervision background of the dormitory building and the user's terminal device, immediately cuts off the power of the entire dormitory through the power supervision background, triggers the fire alarm and executes the emergency fire protection mechanism.

Specific embodiments

[0040] The technical features of the present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can understand.

[0041] For student dormitories, especially in college student dormitories, the types of electrical appliances that users need to use are relatively limited. For example: laptops, mobile phone chargers, table lamps, fans, hair dryers, hair curlers, kettles, hand warmers, heaters, etc. Therefore, the safety levels of electrical appliances can be divided according to power to facilitate the restriction of the use of high-power electrical appliances in the dormitory; for the bunk bed structure in college student dormitories, in order to facilitate users' electricity use, sockets need to be set in the desk area under the bed and the bed area above the bed; larger power electrical appliances that require AC power, such as hair dryers, hair curlers, kettles, hand warmers, heaters, usually only need to be charged or used in the desk area under the bed, and usually only mobile phone charging jacks need to be set in the bed area above the bed. Therefore, the main body of the intelligent socket is installed in the desk area under the bed, and the intelligent socket is split and installed in the bed area above the bed.

[0042] For this intelligent socket structure, the method for realizing flexible control of the intelligent socket in the student dormitory and the method for monitoring abnormal electricity use are the core of solving the electricity use safety problem in the college student dormitory.

[0043] A control method for an intelligent socket in a student dormitory, its implementation logic is as Figure 1 shown, and the specific operation steps are as follows:

[0044] Step S1: Deploy and install the intelligent socket and configure the hardware functions of the intelligent socket, bind the user terminal device and connect to the power supervision background of the dormitory building;

[0045] Specifically, for the bunk bed structure with a desk below and a bed above in a university dormitory, install the main body of the smart socket in the desk area below and the smart socket split body in the bed area above. Configure a wireless communication module, a human body detection module, a temperature detection module, a smoke detection module, a buzzer, a DC jack module, and several AC socket modules in the main body of the smart socket. Configure a DC on-off control module in the DC jack module, and configure an AC leakage current detection module, an AC on-off control module, and a sampling detection module in each AC socket module. Configure a human body detection module, a temperature detection module, a smoke detection module, and a DC jack module in the smart socket split body.

[0046] Among them, the wireless communication module uses a WiFi module, the AC leakage current detection module uses an AC leakage current sensor, and the sampling detection module is used to detect the output current and voltage of the AC socket module, calculate the output power, and judge whether there is a short circuit condition according to the output current.

[0047] In addition, number several AC socket modules from 1 to N, where N represents the total number of AC socket modules included in a single smart socket. Authenticate the identity of the smart socket corresponding to the bed with the user's terminal device through the wireless communication module, and wirelessly connect the smart socket to the power supervision background of the dormitory building through the wireless communication module. The user's terminal device is generally a mobile phone. After binding with the smart socket, the user can receive and view electricity consumption information and abnormal alarm information through the mobile phone, and can also adjust and set relevant control parameters through the mobile phone, as well as remotely control the power on and off of the smart socket.

[0048] Step S2: Set power control rules based on the hardware functions of the smart socket.

[0049] Specifically, classify electrical appliances into three safety levels according to their power. For example, classify electrical appliances with a power not exceeding 100W as low-risk electrical appliances, such as table lamps, fans, mobile phone chargers, laptop chargers, computer speakers, etc.; classify electrical appliances with a power greater than 100W and not exceeding 500W as medium-risk electrical appliances, such as small hair dryers, curling irons, desktop computer hosts, etc.; classify electrical appliances with a power greater than 500W and not exceeding 1500W as high-risk electrical appliances, such as large hair dryers, kettles, hand warmers, heaters, etc.

[0050] According to the connection status of the wireless communication module with the user terminal device and the detection results of the human body detection module, the intelligent power strip is divided into four working states, namely: the state where the bed is unoccupied and the device is offline, the state where the bed is unoccupied but the device is online, the state where the bed is occupied but the device is offline, and the state where the bed is occupied and the device is online; among them, since the transmission distance of the WiFi module is generally between 100m and 200m, therefore, the state where the bed is unoccupied and the device is offline means that the user has left the dormitory, the state where the bed is unoccupied but the device is online means that the user has temporarily left the bed, the state where the bed is occupied but the device is offline means that someone other than the user approaches the bed or the user's mobile phone is turned off, and the state where the bed is occupied and the device is online means that the user himself / herself has returned to the corresponding bed;

[0051] Specifically, according to the three safety levels of electrical appliances and the four working states of the intelligent power strip, power control rules are established, which are: for the state where the bed is unoccupied and the device is offline, immediately perform a power-off operation; for the state where the bed is unoccupied but the device is online, perform a power-off operation after a set time delay; for the state where the bed is occupied but the device is offline, there is no usage restriction for low-risk electrical appliances, medium-risk electrical appliances are powered off at regular intervals, and high-risk electrical appliances are restricted in use; for the state where the bed is occupied and the device is online, there is no usage restriction for low-risk and medium-risk electrical appliances, and high-risk electrical appliances need to be authorized by the user on the terminal device before use;

[0052] Specifically, when the user inserts an electrical appliance into the AC socket module of the intelligent power strip, the power supply of the AC socket module is in the on state. At this time, the output power is calculated through the current information and voltage information collected by the sampling detection module, and the safety level of the electrical appliance is determined; for low-risk and medium-risk electrical appliances, the corresponding AC socket module continues to conduct; for high-risk electrical appliances, the corresponding AC socket module is powered off after a delay of 30 seconds or 1 minute. At this time, the user needs to authorize on the mobile phone to continue to use the power supply; for electrical appliances with a power exceeding 1500W, such as induction cookers, electric cookers, etc., authorization needs to be applied to the administrator of the power supervision background before use;

[0053] In addition, for some electrical equipment that requires long-term power supply, such as computer power supplies, mobile phone chargers, fish tank oxygen pumps, rechargeable table lamps, etc., after the user's terminal device is bound to the intelligent power strip, the user is allowed to mark some AC socket modules and DC jack modules as long-term power-on slots through the terminal device, which can supply long-term power to low-risk electrical appliances; low-risk electrical appliances plugged into the long-term power-on slots can be exempted from the power-off operation performed in the unoccupied state within a set long period; when medium-risk and high-risk electrical appliances are inserted into the marked long-term power-on slots, the power-off operation is still performed according to the power control rules; among them, the set period is, for example, 12 to 24 hours. When the duration of the unoccupied state exceeds the set period, the power-off operation is performed on the low-risk electrical appliances on the long-term power-on slots, so as to avoid the user forgetting to cut off the power supply of the powered-on electrical appliances when going out during the holiday.

[0054] In addition, when any human detection module in the smart socket main body or the smart socket split detects that there is someone in the bed again, if there is someone in the bed but the device is offline, the DC socket module that was turned off is powered on again because it is highly likely that the device is not bound to a user or the user's mobile phone is turned off. After some electrical appliances are powered off, the power switch of the appliance itself will automatically turn off. Therefore, the AC socket module that was turned off needs to be powered on again for a short time, such as restoring power for 3 seconds, to re-detect the power of the appliance whose power switch is not turned off.

[0055] For low-risk appliances that have not turned off the power switch, the shut-off AC socket module will remain powered on; for medium-risk appliances that have not turned off the power switch, the shut-off AC socket module will be powered on and off at a scheduled time, such as 3 minutes, or the corresponding power-on time will be restored according to the user's power usage habits, and then the power will be cut off again; for high-risk appliances that have not turned off the power switch, the power will continue to be cut off. At this time, the shut-off AC socket module needs to be connected to the user's terminal device and then restarted, or authorized to restart through the power supervision background;

[0056] If the bed is occupied and the device is online, the shut-off AC socket module and DC jack module will be powered on again. At this time, for electrical appliances that have not turned off the power switches, low-risk and medium-risk appliances will remain turned on, and high-risk appliances will be powered off again, requiring the user to re-authorize on the mobile phone before they can continue to use them.

[0057] Step S3: Based on the power control rules, the user's power usage information over a period of time is collected as historical normal data to establish a user's power usage habit model;

[0058] Specifically, the user's electricity consumption information over a period of time is collected as historical normal data, and the collected current data and power data are processed, and the current data and power data corresponding to various electrical appliances are obtained through the sampling detection module; when processing the data, the current data and power data are first converted into analyzable time series features, and 24 hours can be divided into several time windows, for example, one window every 5 minutes, and a total of 288 window points in 24 hours, to reduce storage pressure; then the data is short-time pulse filtered to remove data sequences with a power-on time shorter than a threshold, such as setting the threshold to 30 seconds, that is, to delete data sequences with a time series feature length of no more than 30 seconds, so as to eliminate the noise interference caused by the electrical appliance startup pulse and short-term false touch; since the power of the same electrical appliance is different in different modes, such as the cold air mode and hot air mode of a hair dryer, it is necessary to obtain the current value and operating power corresponding to the user using different electrical appliances and different modes of the electrical appliances, and at the same time, the number of times the user uses the corresponding operating power during the data collection period is counted according to the time window, and the power-on time of each operating power is recorded;

[0059] In addition, divide the total power-on duration at different operating powers by the corresponding number of usage times to calculate and obtain the average power-on duration corresponding to different operating powers when the user uses the electrical appliance. Then, map different operating powers to the corresponding average power-on durations to generate the user's electricity consumption habit model. Moreover, the user's electricity consumption information can be periodically collected and recorded to periodically update the user's electricity consumption habit model, such as updating it once a week or once a month, to conform to the user's living habits.

[0060] Step S4: Based on the user's electricity consumption habit model, adjust the set parameters of the power control rule.

[0061] Specifically, adjust the delay setting duration for performing the power-off operation when the bed is unoccupied and the device is in the online state. Set the average power-on durations corresponding to different operating powers as the delay parameters for the electrical appliances with the corresponding operating powers when powering off. For example, in the case where the bed is unoccupied and the device is in the online state, the user may temporarily leave the corresponding bed. If the kettle is boiling water at this time, the power-off delay parameter needs to correspond to the average duration of boiling water once by the user usually, so as to ensure that the kettle can boil the water and avoid the electrical appliance powering off too early when the user temporarily leaves the corresponding bed, resulting in the operating effect of the electrical appliance not meeting the user's expectations.

[0062] In addition, adjust the duration parameter for the timed power-off use of medium-risk electrical appliances when the bed is occupied and the device is in the offline state. Set the average power-on durations corresponding to the operating powers within the power range of medium-risk electrical appliances as the duration parameters for the timed power-off use of the electrical appliances with the corresponding operating powers. For example, in the case where the bed is occupied and the device is in the offline state, the user's mobile phone may be turned off. In order not to affect the user's use of medium-risk electrical appliances such as hair dryers and curling irons, the duration parameter for the timed power-off use in the power control rule needs to correspond to the duration of using the hair dryer or curling iron by the user usually, so that the user can use the electrical appliance completely to complete the required operations.

[0063] Step S5: Obtain the detection information data at the current sampling moment, calculate the abnormal risk value, and determine the risk level.

[0064] Specifically, calculating the abnormal risk value at the current sampling moment includes: real-time collecting the current data and power data of each AC socket module, as well as the temperature data detected by the temperature detection modules in the smart socket main body and the smart socket splitter respectively, and obtaining the abnormal trigger signals of the smoke detection module and the AC leakage current detection module. Since the output voltage and output current of the DC jack module are relatively small, and the power of the plugged-in electrical appliances is within the safe range, for student dormitories, the potential safety hazards of electricity consumption are often caused by large-power electrical appliances plugged into the AC socket module. Therefore, in order to reduce the amount of calculation and enhance the response speed of the smart socket, only the relevant data of the AC socket module needs to be considered.

[0065] Obtain the short - circuit risk value \(I\) at the \(t\) - th sampling moment through the collected current data Y,t : When \(I\) t,n \(\geq k\times I\) t-1,n , it indicates that the output current of the \(n\) - th AC socket module surges, and the connected electrical appliance has a short - circuit condition. When any AC socket module has a short - circuit condition, \(I\) Y,t = 1; When \(I\) t,n \(< k\times I\) t-1,n , it indicates that the output current of the \(n\) - th AC socket module is normal, and the connected electrical appliance is normal. When all AC socket modules have no short - circuit condition, \(I\) Y,t = 0; \(I\) t,n represents the output current value of the \(n\) - th AC socket module at the \(t\) - th sampling moment, and \(I\) t-1,n represents the output current value of the \(n\) - th AC socket module at the \((t - 1)\) - th sampling moment. \(k\) represents the short - circuit threshold parameter, and the value range of \(n\) is from 1 to \(N\); Generally, when the instantaneous current of ordinary household appliances suddenly surges by 5 - 10 times, it indicates a short - circuit. Therefore, the value range of \(k\) is 5 - 10;

[0066] When \(t = 1\), by default, \(I\) Y,t = 0. When \(t\geq2\), comparison and judgment start. Since the current data is collected in real - time, the sampling frequency of the sampling detection module is not less than 100Hz, and the interval time for short - circuit condition judgment does not exceed 0.01 seconds; When a short - circuit occurs, due to the delay effect caused by the characteristics of inductance, capacitance, and power supply internal resistance in the electrical appliance circuit, the short - circuit current takes a certain time to reach the peak, and the growth change time of the current is much longer than 0.01 seconds; Therefore, by default, the short - circuit risk value at \(t = 1\) is zero, which does not affect the timely detection and feedback of the short - circuit condition and can avoid the risk of missed reports;

[0067] Obtain the leakage risk value \(D\) at the \(t\) - th sampling moment by detecting the leakage current signal of the AC leakage current detection module Y,t : According to the characteristics of the AC leakage current sensor, when \(D\) t,n >0, it indicates that the electrical appliance connected to the \(n\) - th AC socket module has a leakage phenomenon. When any AC socket module has a leakage condition, \(D\) Y,t = 1; When \(D\) t,n = 0, it indicates that the electrical appliance connected to the \(n\) - th AC socket module has no leakage phenomenon. When all AC socket modules have no leakage phenomenon, \(D\) Y,t = 0; \(D\) t,n represents the leakage current value of the \(n\) - th AC socket module at the \(t\) - th sampling moment;

[0068] Obtain the temperature risk value \(T\) at the \(t\) - th sampling moment through the collected temperature data Y,t :

[0069] \(T\) Y,t= sigmoid(β×(T t,max - T0)),

[0070] That is:

[0071]

[0072] In the formula, sigmoid() represents the sigmoid function, e represents the natural constant, β represents the hyperparameter, and T t,max represents the maximum temperature detected by the temperature detection modules in the main body of the intelligent socket strip and the intelligent socket strip sub - body at the t - th sampling moment respectively, T0 represents the abnormal critical temperature value, and the value of the hyperparameter β is 0.1, which is used to scale the magnitude of T Y,t The value range of the temperature risk value is 0 < T Y,t < 1; Generally, the value of the abnormal critical temperature value T0 is 50 °C;

[0073] When an abnormal power consumption occurs, combining the detection of temperature can effectively judge the risk of causing a fire. However, in order to avoid misjudgment of the risk level and prevent the fire alarm from being triggered falsely, it is necessary to improve the accuracy of risk level determination to improve the accuracy of hierarchical alarm; Therefore, for the calculation of the temperature risk value, it is necessary to fit as closely as possible to the impact of temperature change on the occurrence of a fire under actual conditions; Since there is a temperature detection module in each of the main body of the intelligent socket strip and the intelligent socket strip sub - body, which can detect the temperature of the upper and lower two areas corresponding to the beds respectively, in order to reduce the influence of distance on the detected temperature, it is necessary to compare the temperature values detected by the two temperature detection modules and take the maximum temperature value among them to participate in the calculation of the temperature risk value; In order to quantify the risk of causing a fire through temperature data, it is necessary to set an abnormal critical temperature to measure the abnormality of the current temperature data. Considering the temperature range of the actual weather environment, the set abnormal critical temperature needs to be slightly higher than the maximum value of the local actual weather environment temperature. When the temperature value collected by the temperature detection module is higher than the abnormal critical temperature, it indicates that there is a relatively obvious temperature abnormality in the accessories of the intelligent socket strip;

[0074] Generally, the higher the temperature, the greater the fire risk. The higher the current detected temperature exceeds the abnormal critical temperature, the risk of causing a fire will increase sharply; Moreover, the fire warning model usually uses the sigmoid function to process temperature data. The sigmoid function has the characteristic that its output is between 0 and 1, which is suitable for representing probability, and there will be a rapid increase near the critical value, which is consistent with the phenomenon that the fire risk increases sharply with the increase of temperature; At the same time, in the calculation, in order to limit the temperature risk value within a suitable range for the next step of risk level determination, it is necessary to set a hyperparameter to scale the difference between the current detected temperature value and the abnormal critical temperature value, so the above - mentioned formula for calculating the temperature risk value can be derived;

[0075] By detecting the abnormal trigger signal of the smoke detection module, obtain the smoke risk value W at the t-th sampling moment Y,t : When an abnormal trigger signal sent by any smoke detection module within the smart socket main body and the smart socket sub-body is detected, it indicates that the smoke concentration in the dormitory exceeds the set threshold, and W Y,t = 1. When none of the smoke detection modules within the smart socket send an abnormal trigger signal, it indicates that the smoke concentration is normal, and W Y,t = 0;

[0076] Combine the short-circuit risk value I Y,t , the leakage risk value D Y,t , the temperature risk value T Y,t , and the smoke risk value W Y,t with their corresponding weight values respectively, and calculate the abnormal risk value Y of the smart socket at the t-th sampling moment t . The calculation formula is:

[0077] Y t = a × I Y,t + b × D Y,t + c × T Y,t + d × W Y,t ,

[0078] In the formula, Y t represents the abnormal risk value of the smart socket at the t-th sampling moment, a, b, c, and d represent weight values, I Y,t represents the short-circuit risk value at the t-th sampling moment, D Y,t represents the leakage risk value at the t-th sampling moment, T Y,t represents the temperature risk value at the t-th sampling moment, and W Y,t represents the smoke risk value at the t-th sampling moment. Among them, the set weight values satisfy a + b + c + d = 1.5;

[0079] Since the detection and judgment results of short-circuit risk, leakage risk, temperature risk, and smoke risk have different influence weights on the judgment of electrical safety and the judgment of the risk of causing a fire, therefore, it is necessary to set weights for the risk values of the four factors respectively to comprehensively judge the risk of electrical safety hazards causing a fire. The weight values can be adjusted and set through simulation training to improve accuracy and reduce the false alarm rate. Preferably, the values of the weight values are: a = 0.2, b = 0.2, c = 0.6, d = 0.5;

[0080] When a real fire breaks out, the smoke sensor is triggered. At this time, the abnormal risk value calculated by combining the smoke risk value and the temperature risk value must be within the range of the third-level risk level. Thus, while preventing the omission of fire hazards, it can avoid false alarms of the smoke sensor caused by users smoking in the dormitory, resulting in the triggering of the fire alarm. At the same time, during the actual use of electrical appliances, if only leakage or short circuit occurs and the temperature change is small, the probability of a fire caused in this case is small. Therefore, setting the weight value of the short-circuit risk value to 0.2, the weight value of the leakage risk value to 0.2, the weight value of the temperature risk value to 0.6, and the weight value of the smoke risk value to 0.5 can not only timely remind users and dormitory managers to pay attention to potential safety hazards when the temperature is normal but there are abnormal electricity usage or smoke, but also reduce the probability of false alarms and improve the accuracy of alarm triggering when a fire occurs.

[0081] In addition, the risk level is determined according to the calculated abnormal risk value, which are respectively: when 0 < Y t < 0.2, the risk level is zero level, indicating that the smart socket and the powered electrical appliances are operating normally at the t-th sampling moment; when 0.2 ≤ Y t < 0.4, the risk level is the first level, indicating that the smart socket and the powered electrical appliances have short circuits, leakage, or slight temperature abnormalities at the t-th sampling moment; when 0.4 ≤ Y t < 0.7, the risk level is the second level, indicating that the smart socket and the powered electrical appliances have short circuits or leakage conditions and at the same time have large temperature abnormalities at the t-th sampling moment; when 0.7 ≤ Y t < 1.5, the risk level is the third level, indicating that there is a serious temperature abnormality and the smoke concentration exceeds the threshold, and a fire has occurred;

[0082] Step S6: In response to the determination result of the risk level, based on the power control rule, trigger an abnormal alarm of the corresponding level;

[0083] Specifically, when the risk level is at the first level, immediately cut off the power output of the corresponding abnormal communication socket module, trigger the buzzer of the smart socket, and at the same time send the abnormal information to the user's terminal device through the wireless communication module to remind the user to eliminate the hidden danger in time. When in the device offline state, the wireless communication module sends the abnormal information to the power supervision background of the dormitory building to remind the relevant management personnel to check in time; when the risk level is at the second level, immediately cut off the power output of the entire smart socket, trigger the buzzer of the smart socket, and at the same time send the abnormal information to the power supervision background of the dormitory building and the user's terminal device through the wireless communication module to remind the relevant management personnel and users to eliminate the potential safety hazard in time; when the risk level is at the third level, immediately cut off the power output of the entire smart socket, and the wireless communication module urgently sends the abnormal information to the power supervision background of the dormitory building and the user's terminal device, and cuts off the power of the entire dormitory immediately through the power supervision background, triggers the fire alarm and executes the emergency fire protection mechanism; the power supervision background can be associated with the emergency fire protection equipment. For example, when the power supervision background is associated with the sprinkler device, when the fire alarm is triggered and the emergency fire protection mechanism is executed, the sprinkler device corresponding to the dormitory can be immediately started to perform the fire extinguishing operation.

[0084] In addition, for the state where the bed is unoccupied and the device is offline, when the smart socket detects an abnormality, for the determination results of the first-level and second-level risk levels, the risk level is raised by one level and the corresponding abnormal alarm is triggered; an overload protection mechanism can also be set. When the sum of the output powers of each AC socket module, that is, the total output power of the smart socket exceeds the set threshold, an abnormal alarm is triggered; for example, when the total output power of the smart socket is greater than 3000W, the abnormal alarm corresponding to the second-level risk level is executed.

[0085] A control system for a smart socket in a student dormitory is used to implement the above-mentioned smart socket control method, and its hardware structure is as Figure 2 shown, including: a smart socket main body installed in the desk area under the bed, and a smart socket split body installed in the bed area above the bed.

The AC leakage current sensor 14 and the sampling and detection circuit 16 are provided in each of the AC socket modules 8 to achieve independent detection and control of a single AC socket module 8. Even if an electrical appliance connected to one of the AC socket modules 8 has a leakage or short circuit condition, only the corresponding AC on-off control circuit 15 needs to be disconnected, without affecting the conduction of other AC socket modules 8.

[0087] In the intelligent socket body, there are provided a second auxiliary power circuit 17 electrically connected to the power conversion circuit 2 and a sub-control circuit 18 electrically connected to the main control circuit 1. The sub-control circuit 18 is electrically connected to a second group of the human body detection modules 4, temperature detection modules 5, and smoke detection modules 6, and is also electrically connected to a plurality of DC jack modules 9.

Preferably, considering the comprehensive detection requirements and sensor costs, a human body infrared sensor is selected. The temperature detection module 5 adopts a temperature sensor, and the smoke detection module 6 adopts a smoke sensor. The AC leakage current sensor 14 is installed around the ground wire of the AC socket module 8. When the insulation of the energized electrical appliance is normal, the currents flowing through the AC leakage current sensor 14 are equal in magnitude and opposite in direction, and its output signal is zero. When the energized electrical appliance has a leakage condition, there is a differential current flowing through the AC leakage current sensor 14, and the output of the AC leakage current sensor 14 is greater than zero. The DC on-off control circuit 21 can adopt a MOS tube for on-off control. The AC on-off control circuit 15 uses a relay to control the on-off of the AC output power supply.

[0089] In addition, the main control circuit 1 is also electrically connected to a display module 19 and a key circuit 20. The DC jack module 9 includes a DC on-off control circuit 21 and a DC output port 22. The DC output port 22 includes a plurality of USB interfaces, a Type-C interface, and a round DC interface. Among them, the display module 19 can adopt a display screen, a touch display screen, or a digital tube, which is used to display the total power consumption of the currently powered electrical appliance or the power consumption information, and can also set the indicator light corresponding to the AC socket module 8.
