Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating a method for detecting USB interface plugging according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of the method illustrated in fig. 1 when a USB plug is plugged. As shown in fig. 1-2, the USB interface plugging detection method provided in this embodiment is applied to a terminal device, and a USB tail plug is disposed on a main board of the terminal device, wherein an opening shape of the USB tail plug is a closed shape formed by a short side of the USB tail plug, a long side of the USB tail plug, and a side of the USB tail plug for connecting the short side of the USB tail plug and the long side of the USB tail plug, and the short side of the USB tail plug and the long side of the USB tail plug are parallel to each other. In addition, be provided with the USB slot on the lateral wall of terminal equipment's shell, and USB tail plug 1 pegs graft in the USB slot, and USB slot 1 is close to and is provided with range sensor 3 on the long limit 12 of USB slot 1 open-ended USB slot, and this range sensor 3 can be the piece formula, also can be multipoint type, does not carry out specific injecing to this range sensor's kind and the mode that arranges in this embodiment, only needs to guarantee that this range sensor's measurement width scope is greater than the length of USB slot minor face can. The terminal device involved in this embodiment may be an electronic device such as a smart phone, a tablet computer, and an electronic book reader with a USB interface. With reference to fig. 1, the method for detecting the USB interface plugging provided in this embodiment includes:
Specifically, referring to fig. 2, when the user inserts the USB plug 2 into the USB slot 1 on the terminal device case, one side of the USB plug 2 must enter the range of the range sensor 3. With continued reference to fig. 2, the distance measuring sensor 3 shown in fig. 2 is disposed on the long side 11 of the USB slot 1 close to the opening of the USB slot 1, and when the USB plug 2 is correctly inserted into the USB tail 1, the distance measuring sensor 3 will measure the distance from the distance measuring sensor 3 to the long side 22 of the USB plug on the USB plug 2. Because the length of the long side 22 of the USB plug is longer than the length of the short side 21 of the USB plug, after the USB plug 2 is correctly inserted into the USB slot 1, the long side 22 of the USB plug can shield the short side 21 of the USB plug, so that the distance sensor 3 can only measure the distance from the distance sensor 3 to the long side 22 of the USB plug on the USB plug 2, and the distance from the distance sensor 3 to the short side 21 of the USB plug on the USB plug 2 cannot be obtained. In the case that the USB plug 2 is correctly inserted into the USB slot 1, the terminal device obtains the distance data measured by the distance measuring sensor 3 only by the distance from the distance measuring sensor 3 to the long side 22 of the USB plug on the USB plug 2.
Fig. 3 is a schematic structural diagram of the USB plug in the reverse plug state in the method shown in fig. 1. As shown in fig. 3, when the USB plug 2 is inserted into the USB tail 1, the distance sensor 3 measures the distance between the distance sensor 3 and the long side 22 of the USB plug 2 and the distance between the distance sensor 3 and the short side 21 of the USB plug 2. Because the length of the short side 21 of the USB plug is shorter than the length of the long side 22 of the USB plug, after the USB plug 2 is inserted into the USB slot 1, the short side 21 of the USB plug does not shield the long side 22 of the USB plug, so that the distance measuring sensor 3 can not only obtain the distance from the distance measuring sensor 3 to the short side 21 of the USB plug on the USB plug 2, but also obtain the distance from the distance measuring sensor 3 to the long side 22 of the USB plug on the USB plug 2. Therefore, in the case where the USB plug 2 is inserted into the USB slot 1, the distance data measured by the distance measuring sensor 3 obtained by the terminal device includes both the distance from the distance measuring sensor 3 to the long side 22 of the USB plug 2 and the distance from the distance measuring sensor 3 to the short side 21 of the USB plug 2.
And 102, the terminal equipment judges whether the number of the distance values in the distance data is the same as the number of the preset distance values, and if the judgment result is negative, the step 103 is executed.
Specifically, when the distance measuring sensor 3 is provided on the slot long side 11 of the USB slot 1 near the opening of the USB slot 1, the number of the preset distance values in the distance data in the terminal device is one. It can be seen that, under the condition that the USB plug 2 is correctly inserted into the USB slot 1, the distance data measured by the distance measuring sensor 3 obtained by the terminal device is only the distance from the distance measuring sensor 3 to the long side 22 of the USB plug on the USB plug 2, and the distance value in the distance data at this time is only one and is consistent with the number of the preset distance values in the distance data in the terminal device; on the other hand, when the USB plug 2 is inserted into the USB slot 1 in the opposite direction, the terminal device obtains the distance data measured by the distance measuring sensor 3, and the distance data includes the distance from the distance measuring sensor 3 to the long side 22 of the USB plug 2 and the distance from the distance measuring sensor 3 to the short side 21 of the USB plug 2, and the distance data at this time includes two distance values.
Therefore, the terminal device can determine whether the current state in which the USB plug 2 is inserted into the USB slot 1 is the forward insertion state or the reverse insertion state by determining whether the number of distance values in the distance data is the same as the number of preset distance values.
And 103, the terminal equipment reminds the user that the USB interface plugging mode is incorrect.
Specifically, when the distance measuring sensor 3 is disposed on the long side 11 of the slot of the USB slot 1 close to the opening of the USB slot 1, if the distance data measured by the distance measuring sensor 3 obtained by the terminal device contains the distance from the distance measuring sensor 3 to the long side 22 of the USB plug on the USB plug 2 and the distance from the distance measuring sensor 3 to the short side 21 of the USB plug on the USB plug 2, at this time, the USB plug 2 is in the reverse insertion state, and the terminal device reminds the user that the USB interface insertion mode is incorrect.
In this embodiment, the distance from the ranging sensor to the USB plug is obtained by using the ranging sensor arranged on one side of the USB slot, and because the length of the long side of the USB plug is longer than the shape characteristic of the length of the short side of the USB plug, the distance data obtained by the ranging sensor is different between the correct insertion state and the reverse insertion state of the USB plug, and then the number of the currently obtained distance values is compared with the number of the preset distance values, if the number of the currently obtained distance values is different from the number of the preset distance values, the terminal device will remind the user that the current USB interface insertion mode is incorrect. After the user acquires the prompt signal, the direction of the USB plug can be adjusted in time to be correctly inserted, so that the tail plug and the plug are protected, and the service life of the tail plug and the plug can be effectively prolonged.
Fig. 4 is a flowchart illustrating a method for detecting USB interface plugging according to another embodiment of the present invention, and fig. 5 is a schematic structural diagram illustrating a USB plug in the method illustrated in fig. 4 in a state of being plugged. As shown in fig. 4 to fig. 5, the USB interface plugging detection method provided in this embodiment is applied to a terminal device, and a USB tail plug is disposed on a main board of the terminal device, wherein an opening shape of the USB tail plug is a closed shape formed by a short side of the USB tail plug, a long side of the USB tail plug, and a side of the USB tail plug for connecting the short side of the USB tail plug and the long side of the USB tail plug, and the short side of the USB tail plug and the long side of the USB tail plug are parallel to each other. In addition, be provided with the USB slot on the lateral wall of terminal equipment's shell, and the USB tail is inserted and is pegged graft in USB slot 1, and USB slot 1 is close to USB slot 1 open-ended USB slot long limit and is provided with range sensor 3, and this range sensor 3 can be the piece formula, also can be multipoint type, does not carry out concrete injecing to this range sensor's kind and the mode of arranging thereof in this embodiment, only need to guarantee that this range sensor's measurement width scope is greater than the length of USB slot minor face can. The terminal device involved in this embodiment may be an electronic device such as a smart phone, a tablet computer, and an electronic book reader with a USB interface. With reference to fig. 1, the method for detecting the USB interface plugging provided in this embodiment includes:
Specifically, referring to fig. 4, when the user inserts the USB plug 2 into the USB slot 1 on the terminal device case, one side of the USB plug 2 must enter the range of the range sensor 3. With continued reference to fig. 4, the distance measuring sensor 3 shown in fig. 4 is disposed on the short side 11 of the USB slot 1 close to the opening of the USB slot 1, and when the USB plug 2 is correctly inserted into the USB tail 1, the distance measuring sensor 3 will measure the distance from the distance measuring sensor 3 to the long side 22 of the USB plug 2 and the distance from the distance measuring sensor 3 to the short side 21 of the USB plug 2. Because the length of the long side 22 of the USB plug is longer than the length of the short side 21 of the USB plug, after the USB plug 2 is correctly inserted into the USB slot 1, the short side 21 of the USB plug cannot block the long side 22 of the USB plug, so that the distance sensor 3 can measure the distance from the distance sensor 3 to the long side 22 of the USB plug 2 and the distance from the distance sensor 3 to the short side 21 of the USB plug 2. Therefore, in the case where the USB plug 2 is correctly inserted into the USB slot 1, the terminal device acquires the distance data measured by the distance measuring sensor 3 and includes the distance from the distance measuring sensor 3 to the long side 22 of the USB plug 2 and the distance from the distance measuring sensor 3 to the short side 21 of the USB plug 2.
Fig. 6 is a schematic structural diagram of the USB plug in the reverse plug state in the method shown in fig. 4. As shown in fig. 6, when the USB plug 2 is inserted into the USB tail 1, the length of the long side 22 of the USB plug is longer than the length of the short side 21 of the USB plug, so that after the USB plug 2 is inserted into the USB slot 1, the short side 21 of the USB plug is shielded by the long side 22 of the USB plug, and the distance measuring sensor 3 can only measure the distance from the distance measuring sensor 3 to the long side 22 of the USB plug 2, and cannot obtain the distance from the distance measuring sensor 3 to the short side 21 of the USB plug 2. In the case that the USB plug 2 is reversely inserted into the USB slot 1, the terminal device obtains the distance data measured by the distance measuring sensor 3 only by the distance from the distance measuring sensor 3 to the long side 22 of the USB plug on the USB plug 2.
Specifically, when the distance measuring sensor 3 is provided on the slot long side 11 of the USB slot 1 near the opening of the USB slot 1, the number of the preset distance values in the distance data in the terminal device is one. It can be seen that, under the condition that the USB plug 2 is correctly inserted into the USB slot 1, the distance data measured by the distance measuring sensor 3 obtained by the terminal device is only the distance from the distance measuring sensor 3 to the long side 22 of the USB plug on the USB plug 2, and the distance value in the distance data at this time is only one and is consistent with the number of the preset distance values in the distance data in the terminal device; on the other hand, when the USB plug 2 is inserted into the USB slot 1 in the opposite direction, the terminal device obtains the distance data measured by the distance measuring sensor 3, and the distance data includes the distance from the distance measuring sensor 3 to the long side 22 of the USB plug 2 and the distance from the distance measuring sensor 3 to the short side 21 of the USB plug 2, and the distance data at this time includes two distance values.
Therefore, the terminal device can determine whether the current state in which the USB plug 2 is inserted into the USB slot 1 is the forward insertion state or the reverse insertion state by determining whether the number of distance values in the distance data is the same as the number of preset distance values.
And step 203, the terminal equipment indicates the vibration motor to work.
Specifically, when the distance measuring sensor 3 is arranged on the short slot side 12 of the USB slot 1 close to the opening of the USB slot 1, if the distance data measured by the distance measuring sensor 3 obtained by the terminal device only contains the distance from the distance measuring sensor 3 to the long side 22 of the USB plug on the USB plug 2, at this time, the USB plug 2 is in the reverse insertion state, the terminal device indicates the vibration motor in the terminal device to work, and the vibration of the vibration motor reminds the user that the current USB interface insertion mode is incorrect. In addition, optionally, the user can be reminded by flashing the indicator light. It should be noted that, in this embodiment, the user prompting manner is not specifically limited, and only when the USB interface is incorrectly plugged, the terminal device can effectively prompt the user.
