Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
OTG refers to (On-The-Go), a technology for transmitting data, mainly applied to directly transmit data between different devices or mobile devices without a host.
As devices are designed more and more compact, such as smartwatches, smartbracelets, walkman, etc., users have increased the need for these portable small smart devices to transmit data.
There is a USB connector that the connector of USB connecting wire is the USB connector that has magnetic property, and this USB connector aim at is in the same place firmly through the USB data interface end of magnetic property with equipment and USB connector when charging, has avoided electric leakage and other bad condition of contact. And if the USB connector with magnetic property has an OTG function, the USB connector has 5 pins (Vbus, D+, D-, ID, GND).
The inventor creatively discovers that the magnetic property and OTG function of the USB connector can be utilized to realize the control of the OTG function with an intelligent equipment instrument with a Hall sensor.
Based on this, the application provides a control method of OTG function, which can be applied to various portable small intelligent devices with hall sensors, such as smart watches, smart bracelets, etc., and herein, the smart watches are exemplified, the hall sensors are integrated in the original hardware configuration of the smart watches, the hall sensors are magnetic field sensors made according to the hall effect, when magnetic objects approach and get away, certain magnetic field changes are generated, and the hall sensors can detect the magnetic field changes.
The technical scheme of the application is realized by combining the characteristics of the Hall sensor and the USB connector with magnetic characteristics: when the USB connector with the magnetic characteristic is close to the intelligent watch, the Hall sensor detects a certain magnetic field intensity, and the USB connector with the magnetic characteristic is confirmed to be close; and detecting whether the USB connector with the magnetic characteristic is inserted into the USB data interface of the intelligent watch or not, when the USB connector with the magnetic characteristic is detected to be inserted into the USB data interface of the intelligent watch, sending a starting trigger signal to the Hall sensor, pulling down an ID pin of the USB data interface through the starting trigger signal, detecting the pulled down ID pin by the intelligent watch, and correspondingly starting an OTG function.
Specifically, please refer to fig. 1, which is a schematic flow chart of an OTG function control method in an embodiment of the present application, the method specifically includes the following steps:
Step 101, obtaining the target magnetic field intensity detected by the Hall sensor and obtaining the change condition of the access state of the USB data interface.
Step 102, determining whether to start the OTG function of the intelligent watch according to the target magnetic field intensity and the change condition of the access state of the USB data interface.
When an object with magnetic characteristics is close to the intelligent watch, the Hall sensor can detect certain magnetic field intensity, the detected magnetic field intensity is used as target magnetic field intensity, and the target magnetic field intensity is used for determining whether the object with magnetic characteristics close to the intelligent watch is a USB connector with magnetic characteristics; the access state of the USB data interface comprises an accessed state in which the USB connector is inserted and an unaccessed state in which the USB connector is not inserted. Further, the changing conditions of the access state include: the USB connector is inserted into the USB data interface of the intelligent watch from the unaccessed state to the accessed state, or the USB connector is pulled out of the USB data interface of the intelligent watch from the accessed state to the unaccessed state, and whether the USB connector is inserted into the USB data interface of the intelligent watch can be determined by analyzing the change condition of the access state of the USB data interface.
It can be understood that when an object with magnetic characteristics approaches the smart watch, if the access state is changed from the unaccessed state to the accessed state, it can be determined that the object with magnetic characteristics is a USB connector with magnetic characteristics at this time, under the scene, a start trigger signal can be sent to the hall sensor, the ID pin of the USB data interface is pulled down by the start trigger signal, at this time, the smart watch detects the pulled-down ID pin, and the OTG function is controlled to be started.
In a possible implementation manner, the obtaining the target magnetic field strength detected by the hall sensor in step 101 and the obtaining the change condition of the access state of the USB data interface are obtained in real time, and based on this, step 101 and step 102 specifically include the following steps:
a. Acquiring the target magnetic field intensity detected by the Hall sensor and the change condition of the access state of the USB data interface at the same time in real time;
b. when the target magnetic field intensity is larger than or equal to the preset magnetic field threshold value at the same moment and the interface state of the USB data interface is unchanged, continuing to return to the execution step a;
c. When the target magnetic field intensity is greater than or equal to a preset magnetic field threshold value at the same moment and the interface state of the USB data interface is changed into an accessed state, the USB connector is a magnetic USB connector, a starting trigger signal is sent to the Hall sensor, and an ID pin of the USB data interface is pulled down through the starting trigger signal so as to start the OTG function of the intelligent watch;
d. and stopping controlling the OTG function when the target magnetic field intensity at the same moment is smaller than the preset magnetic field threshold value.
The preset magnetic field threshold value is a preset magnetic field critical value, and the USB connector with magnetic characteristics is determined to be close to the intelligent watch only when the magnetic field strength detected by the Hall sensor in real time is greater than or equal to the critical value, so that the change condition of the access state of the USB data interface is continuously detected.
It can be understood that in step b, when the obtained target magnetic field strength is greater than or equal to the preset magnetic field threshold at a certain moment, and meanwhile, the interface state of the USB data interface is not changed, it is determined that the object with magnetic characteristics close to the smart watch is a USB connector with magnetic characteristics, but the USB connector is not inserted into the USB data interface, so that the step a is continuously executed, and the step a is re-obtained; in step c, when the acquired target magnetic field intensity is greater than or equal to a preset magnetic field threshold at a certain moment, and meanwhile, the interface state of the USB data interface is changed from a non-accessed state to an accessed state, it is determined that an object with magnetic characteristics close to the intelligent watch is a USB connector with magnetic characteristics, and the USB connector is inserted into the USB data interface of the intelligent watch, at the moment, a starting trigger signal is sent to the Hall sensor, an ID pin of the USB data interface is pulled down through the starting trigger signal, at the moment, the intelligent watch detects the pulled down ID pin, and the intelligent watch starts an OTG function; in step d, when the obtained target magnetic field strength is smaller than the preset magnetic field threshold at a certain moment, it is determined that the object with magnetic characteristics close to the smart watch is not the USB connector with magnetic characteristics, or the USB connector with magnetic characteristics is far away from the smart watch, at this time, control of the OTG function is stopped no matter how the interface state of the USB data interface changes.
In the embodiment of the application, the triggering condition of the Hall sensor is more strict by setting the preset magnetic field threshold value, so that other objects with magnetic characteristics but not meeting the magnetic field strength requirement are prevented from being touched by mistake. And the target magnetic field intensity detected by the Hall sensor and the change condition of the access state of the USB data interface at the same time are obtained in real time, so that the intelligent watch can control the OTG function more accurately.
In a possible implementation manner, before determining to turn on the OTG function of the smart watch in step c, the method may further include selecting and displaying a man-machine interaction interface. Specifically, before the smart watch determines to start the OTG function, a display interface of the smart watch pops up a human-computer interaction interface, and a selection frame is displayed, where the selection frame includes: displaying a selection message for selecting and determining to start the OTG function, or displaying a selection message for selecting and canceling to start the OTG function, and determining to start the OTG function if the user selection is detected to determine to start the OTG function; if the user selects to cancel the starting, the OTG function is not started.
In the embodiment of the application, the experience of the user is further optimized by setting the display interface of man-machine interaction.
It should be noted that, in order to implement the above technical solution, it is necessary to ensure that the initial state of the USB data interface is a non-access state in advance, that is, no other device is inserted in the initial state of the USB data interface. The method specifically comprises the following steps:
Before step 101, the magnetic field intensity detected by the hall sensor is monitored, if the magnetic field intensity detected by the hall sensor is detected to be greater than or equal to a preset magnetic field threshold value, it is determined that an object with magnetic characteristics close to the smart watch is a USB connector with magnetic characteristics, and the interface state of the USB data interface at the same moment is continuously detected. When the interface state is the unaccessed state, determining that the initial state of the USB data interface is the unaccessed state, i.e. no other device is inserted in the initial state of the USB data interface, and at this time, further data acquisition can be started, i.e. the steps 101 and 102 are executed; when the interface state is the accessed state, it is determined that other devices are inserted in the initial state of the USB data interface, and step 101 and step 102 are not needed to be executed again, so that the OTG function cannot be triggered.
In the embodiment of the application, by detecting the initial state of the USB data interface in advance, the situation that other equipment is connected to the USB data interface is avoided, corresponding steps are executed to control the OTG function, unnecessary resource waste is caused, and the control is more accurate.
Further, after determining to start the OTG function of the smart watch in the step c, the present application may also implement switching between the OTG function and the USB function, and referring to fig. 2, a flowchart of a method for switching between the OTG function and the USB function in the embodiment of the present application includes:
step 201, detecting a change condition of an access state of the USB data interface.
Step 202, when detecting that the access state of the USB data interface is changed from the accessed state to the unaccessed state, monitoring the access state of the USB data interface.
Step 203, when it is monitored that the access state of the USB data interface is changed from the unaccessed state to the accessed state within the preset time period, it is determined to turn on the USB function.
It can be appreciated that the method proposed in fig. 2 is based on a secondary plug to implement the OTG function and USB function switching. In step 202, when it is detected that the access state of the USB data interface is changed from the accessed state to the unaccessed state, it is indicated that the USB connector is pulled out from the USB data interface of the smart watch, and the access state of the USB data interface is continuously monitored; detecting that the access state of the USB data interface is changed from the unaccessed state to the accessed state again within the preset time length, indicating that the USB connector is secondarily inserted into the USB data interface of the intelligent watch, and determining that the user needs the USB function at the moment, so that the USB function is started; and stopping controlling the USB function when detecting that the access state of the USB data interface is unchanged within the preset time.
The preset duration may be a very short time threshold, for example, 5s, and the time threshold may be set according to specific needs in practical applications, which is not limited herein.
In a feasible implementation manner, the implementation main body of determining the secondary plugging accurately is the same USB connector, and the specific steps include:
i, recording a first parameter of the USB connector.
Ii obtaining a second parameter of the USB connector.
Iii determining to turn on the USB function when the second parameter is the same as the first parameter.
It can be understood that the first parameter of the USB connector is a relevant parameter of the USB connector when the first detection of the accessed state of the USB data interface is the accessed state, and the specific first detection of the accessed state is in the foregoing step c: when the target magnetic field intensity is greater than or equal to a preset magnetic field threshold value at the same moment and the interface state of the USB data interface is changed into an accessed state, the USB connector is a magnetic USB connector, the OTG function of the intelligent watch is determined to be started, and relevant parameters of the USB connector at the moment are recorded as first parameters; the second parameter of the USB connector is a related parameter of the USB connector when the access state of the USB data interface is detected to be the accessed state within the preset time period, specifically, in step 203: the method comprises the steps of monitoring that the access state of a USB data interface is changed from a non-access state to an accessed state within a preset time period, and recording relevant parameters of a USB connector at the moment as second parameters; comparing the second parameter with the first parameter, if the second parameter and the first parameter are the same, it can be determined that the same USB connector is plugged and unplugged for the second time, and at the moment, the USB function is determined to be started.
Wherein, the related parameters include, but are not limited to, data that can identify the USB connector.
The embodiment aims to provide a more accurate method for realizing switching between an OTG function and a USB function.
The embodiment of the application also provides a method for realizing switching between the OTG function and the USB function besides the secondary plugging method, wherein the method comprises a man-machine interaction interface, and a user can perform real-time manual operation control, and the method is specific: and c, after the OTG function of the intelligent watch is determined to be started, displaying a floating identification window corresponding to the OTG function by the intelligent watch, detecting clicking operation of a user on the floating identification window, if the user is determined to click the floating identification window, further displaying a switching interface of the OTG function and the USB function for the user to select to start the OTG function or the USB function, and switching to the function selected by the user after detecting the switching operation of the user.
For example: the OTG function is selected to be used by a user, so that the OTG function is started; and if the user selects to use the USB function, the starting of the USB function is realized. The aim of the embodiment is to make the experience of the user better.
