[0001] The present application relates to the field of data lines, in particular to a control method and device of an intelligent power-off data line. BACKGROUND

[0002] At present, there are many data lines with intelligent power-off function on the market. When the charging device is fully charged, the intelligent power-off data line will automatically cut off the connection between the data line and the charging device to avoid overcharging the charging device.

[0062] Embodiment 1

[0063] The embodiments of the present application propose a control method of an intelligent power-off data line, please refer to Figure 1 The intelligent power-off data line 10 includes a micro control module 12, a power-off switch module 13, a protocol acquisition module 11, a telecommunication signal data acquisition module 14, and an insertion identification module 15. The micro control module can be a MCU (Microcontroller Unit) or the like, which is used to receive and process information input by the protocol acquisition module, the telecommunication signal data acquisition module, and the insertion identification module, and send control instructions to the power-off switch module. The telecommunication signal data acquisition module is used to acquire telecommunication signal data flowing through the intelligent power-off data line. The power-off switch module is arranged in the intelligent power-off data line, which is used to receive control commands sent by the micro control module to control the on-off of the intelligent power-off data line. The insertion identification module is used to detect whether a device to be charged is inserted, and the protocol acquisition module is used to acquire the communication protocol type of the device to be charged.

[0064] Exemplarily, asFigure 2 As shown, the control method of the intelligent power-off data line includes steps S100-S300.

[0065] Step S100: Real-time acquisition of electrical signal data of the data line, determination of the corresponding target value according to the electrical signal data, and determination of whether the target is less than a first preset value.

[0066] It can be understood that when the intelligent power-off data line insertion recognition module detects that the intelligent power-off data line is inserted into the corresponding device to be charged, and on the intelligent power-off data line, the electrical signal data acquisition module of the intelligent power-off data line will acquire the electrical signal data on the data line in real time, and determine the corresponding target value according to the acquired electrical signal data. The electrical signal data can be any one or more of the voltage value and the current value. When the acquired electrical signal data is the current value, the corresponding target value is the current value; when the acquired electrical signal data is the current value and the voltage value, the corresponding power value will be calculated according to the acquired voltage value and current value, that is, the power value is the target value.

[0067] After determining the target value, it is determined whether the target value is less than the first preset value, in other words, it is determined whether the current value or the power value is less than the corresponding first preset current value or first preset power value. When the target value is less than the first preset value, step S200 is executed; when the target value is greater than or equal to the first preset value, the real-time acquisition of the electrical signal data of the intelligent power-off data line is continued.

[0068] Step S200: Determine a plurality of judgment time lengths starting from the current time point, and determine whether the target value in each judgment time length satisfies the corresponding power-off condition.

[0069] In the present application, each judgment time length includes a plurality of time points, and each time point corresponds to an electrical signal data, that is, a target value. When the target value is less than the first preset value, the target value in the plurality of judgment time lengths starting from the current time point is determined, that is, the time point corresponding to the target value less than the first preset value, whether the target value satisfies the corresponding power-off condition. When the target value in each judgment time length satisfies the corresponding power-off condition, step S300 is executed; when there is a judgment time length in the plurality of judgment time lengths in which the target value does not satisfy the corresponding power-off condition, the corresponding step will be executed.

[0070] In one embodiment, as shown in the figure, step S200 includes sub-steps S210-S230. Figure 3

[0071] Sub-step S210: Determine whether the target value in the first judgment time length satisfies the corresponding first power-off condition.

[0072] ​It can be understood that the plurality of determination time lengths can include a first determination time length, a second determination time length and a third determination time length, and the first determination time length, the second determination time length and the third determination time length increase in turn, in other words, the first determination time length is less than the second determination time length, and the second determination time length is less than the third determination time length. Among them, there is a large difference between each determination time length, the first determination time length is the shortest, setting a shorter first determination time length not only can more accurately judge and cyclically count the target value of the data line, but also can improve the judgment efficiency; the second determination time length is relatively long, so as to further judge the target value; the third determination time length is longer, which can more accurately judge the target value of the data line. For example, the first determination time length is set to 5 seconds, the second determination time length is set to 20 seconds, and the third determination time length is set to 45 minutes. In the present application, each determination time length is set according to a hierarchical progressive relationship, which can not only more accurately judge the target value of the data line, but also can avoid misjudgment and affect normal charging.

[0073] When the determined target value is less than the first preset value, the electric signal data of the data line will be continuously collected in real time, and the corresponding target value will be determined. The time is counted from the current time point when the target value is less than the first preset value, and it is determined whether the target value corresponding to each time point in the first determination time length from the current time point is less than the first preset value. If the target value corresponding to each time point in the first determination time length is less than the first preset value, it is determined that the target value in the first determination time length meets the first power-off condition, and the sub-step S220 will be executed. At this time, the intelligent power-off data line will remain in the charging state; if it is determined that the target value of any time point in the first determination time length from the current time point is greater than or equal to the first preset value, that is, if there is a target value greater than or equal to the first preset value in the first determination time length, it is determined that the intelligent power-off data line is in the charging state, the intelligent power-off data line is controlled to remain in the charging state, and the counting operation is cleared from the current time point, that is, the first determination time length counted from the time when the target value is less than the first preset value is cleared, and the step S100 is executed.

[0074] For example, when the target value is the current value, the first preset value is 200 milliamps, and the first determination time length is 5 seconds, if it is determined that the current value is less than 200 milliamps, the current time point is marked as A, and it is determined whether the current value corresponding to each time point in 5 seconds from the current time point A is less than 200 milliamps. If the current value of each time point in 5 seconds is less than 200 milliamps, it is determined that the current value of the intelligent power-off data line in 5 seconds meets the first power-off condition, at this time the intelligent power-off data line will be controlled to remain in the charging state, and the second power-off condition will be continuously judged; if the current value of any time point in 5 seconds is greater than or equal to 200 milliamps, it is determined that the data line is in the charging state, at this time the charging operation will be maintained, and the counting operation will be cleared from the current time point, that is, no counting will be performed, until the next time the target value is less than the first preset value, the counting will be restarted.

[0075] Sub-step S220: determining whether the target value in the second judgment duration satisfies the corresponding second power-off condition.

[0076] In the present application, when the target value in the first judgment duration satisfies the first power-off condition, it is determined whether the target value at each time point in the second judgment duration counted from the current time point is less than the second preset value. If the target value at each time point in the second judgment duration is less than the second preset value, it is determined that the target value in the second judgment duration satisfies the second power-off condition, and sub-step S230 is executed. If the target value at any time point in the second judgment duration is greater than or equal to the second preset value, the counting from the time point at which the target value is greater than or equal to the second preset value, i.e., the current time point, is cleared, and step S100 is executed.

[0077] For example, when the second judgment duration is 20 seconds and the second preset value is 200 mA, after it is determined that the target value at each time point in the first judgment duration is less than the first preset value, the current time point is marked as B, and it is determined whether the target value at each time point in the 20 seconds counted from the current time point B is less than 200 mA. If the target value in the 20 seconds is less than 200 mA, it is determined that the data line satisfies the second power-off condition, the intelligent power-off data line will still be kept charging, and the judgment of the third power-off condition is continued. If the target value at any time point in the 20 seconds is greater than or equal to 200 mA, it is determined that the intelligent power-off data line is in a charging state, and the counting from the current time point is cleared.

[0078] Sub-step S230: determining whether the target value in the third judgment duration satisfies the corresponding third power-off condition.

[0079] It can be understood that when the target value in the second judgment duration satisfies the second power-off condition, it is further determined whether the target value in the third judgment duration counted from the current time point satisfies the corresponding third power-off condition. When the target value in the third judgment duration satisfies the third power-off condition, it is determined that the target value in each judgment duration satisfies the corresponding power-off condition, and step S300 is executed. When the target value in the third judgment duration does not satisfy the third power-off condition, sub-step S230 is executed.

[0080] In an embodiment, as shown in FIG. 2, sub-step S230 includes sub-steps S231-S233. Figure 4

[0081] Sub-step S231: determining whether the target value at each time point in the third judgment duration counted from the current time point is less than a third preset value.

[0082] ​It can be understood that, from the time point when the target value in the second judgment duration meets the second power-off condition, that is, from the current time point, the target value at each time point in the third judgment duration is judged whether it is less than the third preset value, if the target value at each time point in the third judgment duration is less than the third preset value, it is determined that the target value in the third judgment duration meets the corresponding third power-off condition, and step S300 is executed; if the target value at any time point in the corresponding third judgment duration is greater than or equal to the third preset value, substep S232 is executed.

[0083] Substep S232: record the duration that the target value is greater than or equal to the third preset value from the current time point as the actual interference duration, and determine whether the actual interference duration is less than the preset interference duration.

[0084] When the target value at any time point in the third judgment duration is greater than or equal to the third preset value, the time is counted from the time point when the target value is greater than or equal to the third preset value, that is, from the current time point, the duration that the target value is greater than or equal to the third preset value is recorded as the actual interference duration, and it is judged whether the recorded actual interference duration is less than the preset interference duration. When the actual interference duration is less than the preset interference duration, substep S233 is executed; when the actual interference duration is greater than or equal to the preset interference duration, the time counting from the current time point is cleared, that is, the time counting from the time point when the actual interference duration is greater than or equal to the preset interference duration is cleared, and substep S231 is re-executed.

[0085] Exemplarily, in the present application, the third judgment duration can also be divided into multiple time periods, and the target values in the multiple time periods are detected, when there is a time point in one of the time periods that the target value is greater than or equal to the third preset value, the time is counted from the time point when the target value is greater than or equal to the third preset value, and the duration that the target value is greater than or equal to the third preset value is recorded as the actual interference duration.

[0086] Substep S233: continue to determine whether the target value at each time point in the remaining duration of the third judgment duration is less than the third preset value.

[0087] It can be understood that, if the actual interference duration is less than the preset interference duration, it is determined that the actual interference duration is the time of information interference, for example, when the user receives a short message prompt or temporarily uses, a current surge will be generated. When it is determined that the actual interference duration is information interference, it is continued to judge whether the target value corresponding to each time point in the remaining duration of the third judgment duration is less than the third preset value. In the present application, the first preset value, the second preset value and the third preset value can be the same or different, and the user can set them according to the actual situation, and in the present application, the first preset value, the second preset value and the third preset value are all 200 milliamperes.

[0088] If the target value corresponding to each time point in the remaining time of the third determination time length is less than the third preset value, it is determined that the target value in the third determination time length satisfies the third power-off condition, that is, it is determined that the charging equipment currently charging through the intelligent power-off data line is fully charged, and step S300 is executed. If the target value of any time point in the remaining time of the third determination time length is greater than or equal to the third preset value, the substep S231 is re-executed.

[0089] In an embodiment, as shown in FIG. 8, step S230 further includes substeps S234-S235. Figure 5

[0090] Substep S234: The third determination time length starting from the current time point is divided into multiple time periods, and the number of time periods in which the target value corresponding to each time point is less than the third preset value is determined as the satisfied power-off times.

[0091] It can be understood that after it is determined that the target value of each time point in the second determination time length satisfies the second power-off condition, the third determination time length starting from the current time point is determined, and the third determination time length is divided into multiple time periods, each time period including at least one time point. The time periods in which the target value corresponding to each time point is less than the third preset value are determined, and the corresponding number is recorded as the satisfied power-off times.

[0092] Substep S235: It is determined whether the satisfied power-off times are less than a preset satisfied times.

[0093] After the corresponding satisfied power-off times are recorded, it is determined whether the satisfied power-off times are less than a preset power-off times. When the satisfied power-off times are greater than or equal to the preset satisfied power-off times, step S236 is executed: it is determined that the target value in the third determination time length satisfies the corresponding third power-off condition, and step S300 is executed. When the satisfied power-off times are less than the preset power-off times, the timing starting from the current time point is cleared, and substep S234 is re-executed.

[0094] For example, the third determination time length is 45 minutes, and each time period is 20 seconds. The 45 minutes are divided into 135 time periods of 20 seconds, and the 135 time periods are detected. If the target value in a time period is less than 200 mA within 20 seconds, the time period is considered to satisfy the power-off, and the recorded satisfied power-off times are incremented by one. When the satisfied power-off times are greater than or equal to the preset power-off times, or the probability of the satisfied power-off times in the total number of time periods is greater than or equal to the preset probability, such as 90%, it is determined that the target value in the third determination time length satisfies the third power-off condition.

[0095] Step S300: When the target value in each determination time length satisfies the corresponding power-off condition, the data line is controlled to perform the power-off operation.​

[0096] It can be understood that when the target value in each judgment time length meets the corresponding power-off condition, it is determined that the device to be charged is fully charged at this time, and the data line is powered off by sending a control command to the power-off switch.

[0097] In an embodiment, the intelligent power-off data line further comprises an indication unit.

[0098] It can be understood that when the target value is a power value, it is determined whether the power value is greater than a preset power value; when the power value is greater than the preset power value, the indication unit is controlled to generate a corresponding indication signal; and when the power value is less than or equal to the preset power value, the indication signal is controlled to be turned off after a preset holding time from the current time point. When the indication unit is an indicator light, if the power value is greater than the preset power value, the indicator light is controlled to remain on; and if the power value is less than or equal to the preset power value, the indicator light is controlled to remain on for a preset holding time and then turn off. For example, when the power value is greater than 1W, the data line remains in a charging state, and the indication signal is controlled to remain on; and when the charging is completed and the data line is powered off, i.e., when the power value is less than or equal to 1W, the indicator light is delayed for 1-5 minutes and then turned off.

[0099] When the indication unit is an indicator light, the indication signal can also be a first preset color or a first flashing frequency. When the power value is greater than the preset power value, the indicator light is controlled to display the first preset color or the first flashing frequency; when the power value is less than or equal to the preset power value, the indicator light is controlled to display the first preset color or the first flashing frequency for a preset holding time and then turn off, or the indicator light is controlled to display the first preset color or the first flashing frequency for a preset holding time and then display a corresponding second preset color or a second flashing frequency. The first flashing frequency and the second flashing frequency are obviously different, and the first preset color and the second preset color are also obviously different. For example, the first flashing frequency is one flash per second, and the second flashing frequency is one flash per minute; the first preset color can be green, purple, etc., and the second preset color can be yellow, red, etc.

[0100] In the present application, by setting multiple power-off conditions, i.e., by judging the power-off conditions in multiple judgment time lengths, the misjudgment caused by short message prompts during charging or sudden current changes during temporary use can be avoided, thereby improving the satisfaction of consumers.
