[0067] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0069] Please refer to Figure 1 As shown, the present invention is a control method for an intelligent socket, including the following steps:

[0070] Obtain the temperature data during the socket usage time, and obtain the socket temperature status signal according to the temperature data;

[0071] Among them, the socket temperature status signal includes a temperature qualified signal and a temperature unqualified signal;

[0072] Obtain the current data during the socket usage time, and obtain the socket current status signal according to the current data;

[0073] Among them, the socket current status signal includes a current normal signal and a current abnormal signal;

[0074] Based on the temperature unqualified signal and the current abnormal signal, taking the socket usage time as the analysis object, analyze the influence relationship between the temperature and current during the socket usage, and obtain the over-temperature and over-current influence signal;

[0075] According to the over-temperature and over-current influence signal, identify the occupied state of the socket holes of the socket, and realize the control and adjustment of the number of socket holes and the socket usage time during the usage time of the socket.

[0076] Embodiment 2

[0077] Obtain the temperature data during the socket usage time. The process of obtaining the socket temperature status signal is as follows:

[0078] In a specific embodiment:

[0079] Collect the real-time temperature during the socket usage to obtain the real-time temperature value during the socket usage;

[0080] If the duration of the real-time temperature value during the socket usage being greater than the real-time temperature threshold exceeds the preset duration, it indicates that the temperature during the socket usage is abnormal, and a temperature unqualified signal is generated;

[0081] Otherwise, a temperature qualified signal is generated.

[0082] It should be noted that the temperature non - compliance signal during the use of the power strip indicates that: when the power strip is in use, the temperature of the power strip rises abnormally. When it exceeds the upper limit of the designed temperature rise, it may cause a fire. Secondly, excessive heating of the power strip will lead to energy waste because more electrical energy is converted into heat rather than actual working energy.

[0083] Embodiment 3

[0084] Based on the generated temperature non - compliance signal during the use of the power strip, since abnormal current during the use of the power strip will cause the temperature during the use of the power strip to be non - compliant, analyze and judge whether the temperature non - compliance during the use of the power strip is related to the abnormal current during the use of the power strip. If there is a relationship affected by current, it is convenient to adjust the current in a timely manner during the use of the power strip in the follow - up, reduce the impact of the current on the safety of the power strip during the use process, effectively maintain the temperature stability during the use of the power strip, and further improve the safety during the use of the power strip. Specifically:

[0085] Obtain the current data during the use time of the power strip, and obtain the power strip current status signal according to the current data;

[0086] Among them, the power strip current status signal includes a normal current signal and an abnormal current signal;

[0090] Integrate the unit real - time currents of all time sub - units to obtain the unit real - time current group of the power strip;

[0091] Process the unit real - time current group of the power strip according to the variance calculation formula to obtain the current variance value during the use time of the power strip;

[0094] Among them, obtain the rated current range during the use of the power strip, and record the middle current value within the rated current range as the standard current value during the use of the power strip;

[0095] Multiply the current variance value within the usage time of the power strip by the current deviation ratio within the usage time of the power strip to obtain the current anomaly value of the usage time of the power strip;

[0096] It should be noted that: the larger the current variance value within the usage time of the power strip, the greater the fluctuations of each time sub-unit during the use of the power strip, and the more unstable the use of the power strip; the larger the current deviation ratio within the usage time of the power strip, the greater the current deviation during the usage time of the power strip, and the greater the potential safety hazard in using the power strip;

[0097] Refer to Figure 2 , compare the current anomaly value of the usage time of the power strip with the preset current anomaly threshold of the usage time of the power strip;

[0098] If the current anomaly value of the usage time of the power strip is greater than or equal to the current anomaly threshold of the usage time of the power strip, generate a normal current signal;

[0099] If the current anomaly value of the usage time of the power strip is less than the current anomaly threshold of the usage time of the power strip, generate an abnormal current signal;

[0100] The technical solution of the present invention is: process the current data of the power strip during the usage time of the power strip. This current data is the overall output current value when the power strip is in use. Divide the usage time of the power strip into several time sub-units, and then process the unit real-time current of each time sub-unit to obtain the current variance value and current deviation ratio within the usage time of the power strip. Analyze the current variance value and current deviation ratio within the usage time of the power strip to complete the assessment of the current state during the usage time of the power strip.

[0125] Calculate the ratio of the duration of the overlapping time of lower - temperature and power - off to the total duration of lower - temperature and power - off to obtain the overlapping ratio of lower - temperature and power - off;

[0126] Record the overlapping ratio of upper - temperature and power - off as Swd;

[0129] Refer to Figure 3 , and compare and analyze the overlapping rate of over - boundary temperature and power - off within the socket - strip usage time with the threshold of the overlapping rate of over - boundary temperature and power - off within the socket - strip usage time;

[0130] If the overlapping rate of over - boundary temperature and power - off within the socket - strip usage time is greater than or equal to the threshold of the overlapping rate of over - boundary temperature and power - off within the socket - strip usage time, it indicates that the over - boundary current is related to the over - boundary temperature during the socket - strip usage, and generate an over - boundary temperature - power - off influence signal;
