Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the present invention relates to a charging connection detection method including: acquiring a physical connection state of a target position; detecting the charging current in real time if the physical connection state of the target position indicates that the target position is in a charging state; and if the duration of the detected charging current lower than the first preset threshold is longer than the first preset duration, triggering alarm information for prompting charging disconnection. Through detecting charging current when charging, if detecting that charging current is unusual the system can send out automatically and report an emergency and ask for help or increased vigilance and remind the user, can improve charging stability, practices thrift user's time. The following describes implementation details of the charging connection detection method of the present embodiment in detail, and the following is only provided for easy understanding and is not necessary for implementing the present embodiment.
As shown in fig. 1, the charging connection detection method in the present embodiment specifically includes:
step 101, acquiring a physical connection state of a target position.
Specifically, in order to perform charging connection detection on the target device, it is necessary to first confirm whether the target device is in a charging state, and detect whether the target device is in the charging state by detecting a physical connection state of the target location.
It should be noted that, if the charging connection detection method in this embodiment is applied to the device to be charged, the target position is a charging jack of the device to be charged; or, if the charging connection detection method in this embodiment is applied to the power supply device, the target position is a power supply jack of the power supply device; or, if the charging connection detection method in this embodiment is applied to the charging transmission medium, the target position is a charging plug of the charging transmission medium. As shown in the figure, three application scenarios to which the method is applicable are provided, wherein fig. 2-1 shows that the charging connection detection method in the embodiment is applied to a device to be charged, such as a mobile phone, a notebook, an electric vehicle, an electric toy, a charging clock, and the like, and for example, whether the mobile phone is in a charging state can be determined by detecting whether a charging jack of the mobile phone is connected to a charger plug. Fig. 2-2 shows that the charging connection detection method in the present embodiment is applied to a power supply device, such as a power socket, a power bank, and the like, and determines whether the power bank is charging a mobile terminal device, such as a mobile phone, by detecting whether a power supply jack of the power bank is plugged. Fig. 2-3 show that the charging connection detection method in this embodiment is applied to a charging transmission medium, such as a charging cable, a charger, and the like, and can detect whether a plug of the charger or plugs at one end or both ends of the charging cable are inserted into a jack, and determine whether the cable or the charger is in a charging working state.
And 102, detecting the charging current in real time if the physical connection state of the target position indicates that the target position is in a charging state.
In one example, it may be detected whether the physical connection status of the target location indicates a charging status by: acquiring sensing data of a sensor preset at a target position and used for indicating whether the target position is physically connected with an entity object or not; and if the sensing data indicate that the target position is physically connected with the entity object, judging that the physical connection state of the target position indicates that the target position is in a charging state. Specifically, a sensor may be disposed at the target location to detect a physical connection state of the target location, and the sensing data detected by the sensor may include: pressure sensing data or deformation sensing data. For example, the method is used as a device to be charged or a power supply device, a pressure sensor can be arranged in a charging jack or a power supply jack, whether a charging plug is inserted or not is confirmed by sensing the pressure born in the jack, and whether the device is in a charging state or not is judged; or the method is applied to the charger, the deformation sensor is arranged on the charger plug, when the charging plug is inserted into the jack, part of the structure is deformed, and the deformation is sensed by the sensor, which indicates that the plug is connected with the socket and is in the charging working state.
And judging whether the target equipment is in a charging scene or not by checking the physical connection state of the target position, further checking the charging current if the target equipment is in the charging scene, and detecting whether the charging connection is conducted or not by checking the charging current.
Step 103, if the duration of the detected charging current being lower than the first preset threshold is longer than the first preset duration, triggering an alarm message for prompting the disconnection of the charging.
Specifically, a charging current threshold, that is, a first preset threshold is set, the charging current is greater than the first preset threshold when the charging is normally conducted, and if the charging current is lower than the first preset threshold, the charging connection may be non-conducted, for example, a charger is plugged into a charging jack of a mobile phone, but a power key is not pressed at a power socket position or the socket is physically disconnected after an external force is applied, and the like. At the moment, when the time that the detected current is lower than the first preset threshold value exceeds a certain time, the system triggers alarm information to remind a user that the charging connection is disconnected and needs to be checked and the charging connection is conducted. The alert information includes, but is not limited to: flashing lights, giving out prompt tones, shaking, popping out prompt messages and the like, and selecting the most suitable mode according to the use scene. For example, a warning sound "power supply is disconnected" may be emitted for the electric vehicle, and a warning message "charging disconnected" may be shaken and displayed for the mobile phone.
In one example, it may be determined whether the duration of the charging current being lower than the first preset threshold is greater than the first preset duration by: when the charging current is detected to be lower than a first preset threshold value, starting a first timer for timing; if the timing duration of the first timer is longer than a first preset duration, the duration that the charging current is lower than a first preset threshold value is judged to be longer than the first preset duration. The first timer stops timing and is cleared when the following conditions are met: the charging current is detected to be above a first preset threshold. Specifically, the timer starts to time when the charging current is lower than a first preset threshold, stops timing and clears when the current returns to normal, and determines whether the charging disconnection time length is greater than a preset time length or not according to the time length of the timer, where the first preset time length may be set to different time lengths according to different application scenarios, for example, to 10 seconds, 20 seconds, or 30 seconds. Furthermore, several different first preset durations can be preset for several different scenes for the user to select, or the user can define the first preset duration by self, so that the method is more flexible. For example, the first preset time period for the electric vehicle is set to 10 seconds, the first preset time period for the mobile phone or the toy can be set to 20 seconds, and so on.
After step 103, the present embodiment may further include:
and 104, stopping the alarm of charging disconnection when the charging current is changed from being lower than the first preset threshold value to being higher than the first preset threshold value.
Specifically, the system may automatically remove the alarm after the charging connection is restored to normal. Further, it may also be configured to stop the alarm after receiving an instruction to cancel the alarm, which is input by the user, and the embodiment is not limited.
In the embodiment, when the physical connection state indication of the target position is in the charging state, the charging current is detected in real time; and triggering alarm information for prompting charging disconnection when the charging current is detected to be lower than the first preset threshold value and the duration is longer than the first preset duration. When the charging is unsuccessful, the system can automatically send an alarm to remind the user, so that the charging stability can be improved, and the time of the user is saved.
A second embodiment of the present invention relates to a charging connection detection method. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in the first embodiment, only whether the current is below a first preset threshold is detected. In the second embodiment of the present invention, in addition to checking whether the charging current is lower than the first preset threshold, it is also detected whether the charging current is higher than the second preset threshold. As can be understood by those skilled in the art, the system can guarantee charging safety while guaranteeing charging stability. As shown in fig. 3, the charging connection detection method in the present embodiment specifically includes:
Step 202, judging whether the physical connection state of the target position indicates that the target position is in a charging state, if so, going to step 203; if not, go back to step 201.
Further, after step 205, the method may further include: and step 208, stopping the alarm of charge disconnection when the charging current is changed from being lower than the first preset threshold value to being higher than the first preset threshold value and lower than the second preset threshold value. Step 207 may be followed by: and step 209, stopping the charging overload alarm when the charging current is changed from being higher than the second preset threshold to being higher than the first preset threshold and lower than the second preset threshold.
Step 206 and step 207, specifically, a current lower limit value and a current upper limit value, that is, a corresponding first preset threshold value and a corresponding second preset threshold value, may be preset, and first determine whether a duration of the detected charging current being lower than the first preset threshold value is greater than a first preset duration, and if the duration of the detected charging current being lower than the first preset threshold value is greater than the first preset duration, it indicates that the charging connection is abnormal, and may be that the current is not conducted due to the plug not being inserted or the power key not being pressed, and at this time, an alarm is required to remind of charging disconnection; if the charging current is lower than the first preset threshold, the duration of the detected charging current higher than the second preset threshold is not longer than the first preset duration, whether the duration of the detected charging current higher than the second preset threshold is longer than the second preset duration is further judged, and when the duration of the detected charging current higher than the second preset threshold is longer than the second preset duration, it is indicated that the charging current is too large, a short circuit may be caused because a certain charging connection position is not fully connected or some part of wires are abnormal, and at the moment, a safety risk exists, a user needs to be reminded of charging overload, and loss caused by burning of an electric appliance is avoided. And if the duration that the detected charging current is higher than the second preset threshold value is further judged to be not longer than the second preset duration, indicating that the charging current is normal, continuing to monitor the charging current. It should be noted that the second preset threshold in this embodiment is greater than the first preset threshold.
Further, in order to avoid the erroneous judgment caused by the instantaneous fluctuation of the current, the alarm may be given after the charging current is detected to be abnormal for a certain time, for example, 3 seconds, 5 seconds, and the like. In one example, whether the duration of the charging current higher than the second preset threshold is greater than the second preset duration is determined by: when the charging current is detected to be higher than a second preset threshold value, starting a second timer for timing; and if the timing duration of the second timer is longer than a second preset duration, judging that the duration of the charging current higher than a second preset threshold is longer than the second preset duration. And when the second timer meets the following conditions, stopping timing and clearing the timer: detecting that the charging current is lower than a second preset threshold value. Specifically, whether the duration of the charging current higher than the second preset threshold is longer than the second preset duration is judged through a second timer, and different second preset durations can be set according to different application scenarios. It should be noted that. The first preset time period and the second preset time period in this embodiment may be the same or different, and are set according to actual situations. The warning information of the charging overload includes but is not limited to: the method includes the steps of flashing a lamp, giving out a prompt sound, vibrating, popping out prompt information and the like, wherein the alarm information of charging overload can be set differently from the alarm information of charging disconnection, and can also be set into the same alarm mode, and the embodiment is not limited.
And step 209, stopping the charging overload alarm when the charging current is changed from being higher than the second preset threshold to being higher than the first preset threshold and lower than the second preset threshold.
Specifically, the system may automatically remove the alarm after the charging connection is restored to normal. Further, it may also be configured to stop the alarm after receiving an instruction to cancel the alarm, which is input by the user, and the embodiment is not limited.
Further, if the charging detection method of the embodiment is applied to the device to be charged, the system may also detect the current electric quantity of the device to be charged at the same time, and when the device to be charged is fully charged, the system may also send a warning that the charging is fully charged. Correspondingly, if the charging detection method of the embodiment is applied to the power supply device, such as a charger, the system can also detect the current electric quantity of the power supply device, and when the electric quantity of the power supply device is insufficient, the system can also send a warning of insufficient power supply, so that the waste of charging time is avoided.
In the embodiment, when the physical connection state indication of the target position is in the charging state, the charging current is detected in real time; when detecting that the duration of the charging current lower than a first preset threshold is longer than a first preset duration, triggering alarm information for prompting charging disconnection; and triggering alarm information for prompting charging overload when the charging current is detected to be higher than the second preset threshold value for a duration time longer than the second preset duration time. Charging stability is improved, and meanwhile, charging safety is further guaranteed.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
