Description

Intelligent support and mode starting method

Technical Field

The present application relates to the field of circuits, and in particular, to an intelligent cradle and a mode startup method.

Background

Terminals such as mobile phones and tablet terminals have been widely used, and the functional characteristics of products in these terminals have been enriched. The common power supply interface is a C-Type interface (USB Type-C) or a MICRO-USB interface (MICRO-USB), and the terminals are usually connected to power supply equipment or other equipment to supply power or establish communication with other equipment.

In order to enable the terminal to switch to the working mode, for example: highlighting certain functional characteristics of the product. In the prior art, two different solutions have been proposed. The first scheme is that for a support of a TYPE-C interface, a power delivery (PD IC) chip with a Micro Control Unit (MCU) is usually arranged inside the support for PD protocol communication, and the support needs to communicate with a terminal and a power supply device at the same time, so that two PD controllers need to interact at the same time to achieve the purpose of power supply by a power supply voltage and switching a working mode of the terminal; another solution is to provide a rack with a MICRO USB interface, a customized USB HUB IC (universal serial bus HUB integrated circuit) is usually disposed inside the rack, so that after the terminal, the rack, and the power supply device are connected, data communication between the terminal and the rack can be performed through a customized USB protocol, so as to identify the rack and switch to a working mode.

However, both of these solutions bring technical drawbacks. The first scheme has the problem of involving complex internal control logic and hardware units when two PD controllers interact simultaneously in the process of identifying the bracket; the second scheme needs to use a customized USB HUB IC and a customized USB protocol and device inside the bracket, but the complexity of circuit design is often increased to achieve the purposes of bracket identification and working mode switching; therefore, the two schemes have the problems of complex circuit and higher cost in identifying the bracket to switch the special working mode.

Detailed Description

The scheme of the application provides an intelligent support and a mode starting method, which not only simplifies the circuit structure of the intelligent support, reduces the cost, but also improves the mode starting efficiency.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1a is a schematic product form diagram of an intelligent rack provided in an embodiment of the present application.

As shown in fig. 1a, the intelligent support includes two interfaces, and the two interfaces can respectively support the access of the terminal and the power supply device; the interface C1 is used for connecting with a terminal, and the interface C2 is used for connecting with power supply equipment. And it can be seen from fig. 1a that the interface C1 and the interface C2 are located on the opposite side of the smart bracket, but in practical application, the location and number of the interfaces may be determined according to practical requirements, for example: the location of the interface may be on the same side, or there may be a plurality of interfaces to connect to a plurality of terminal devices, and fig. 1a should not be interpreted as limiting the number and location of the interfaces. In addition, as shown in fig. 1a, the smart bracket can also play a role of support.

In the embodiment of the present application, the mentioned interface may be a TYPE-C interface, a MICRO USB interface, or the like, and is not limited herein.

Fig. 1b is a schematic view of an application scenario of the smart stent provided in the embodiment of the present application.

As shown in fig. 1b, the power supply apparatus can be connected using the interface C1 connection terminal and the interface C2 in fig. 1 a. In the application scenario, the terminal is a tablet computer, and the power supply device is a charger. In practical application, the terminal may also be a mobile phone, a Personal Digital Assistant (PDA), or the like.

Fig. 2a is a schematic structural diagram of an intelligent support provided in an embodiment of the present application.

As shown in fig. 2a, an embodiment of the smart bracket provided in the embodiment of the present application may include:

a first interface 201, a second interface 202 and a communication chip 203; the first interface 201 is connected with a terminal, and the second interface 202 is connected with a power supply device.

When the power supply equipment supplies power to the terminal through the power supply line between the second interface 202 and the first interface 201, the communication chip 203 receives an access signal sent by the terminal, and the access signal is used for the terminal to acquire Identification (ID) information of the intelligent support, so that the terminal starts a target mode when the ID information is matched with preset identification information in the terminal.

In the embodiment of the application, the first interface of the intelligent support is mainly an uplink interface or a male interface connected with a terminal, and the mentioned terminal may be a tablet, a mobile phone and other intelligent devices, and is not limited herein.

The second interface is mainly a downlink port or a female terminal connected to a power supply device, and the mentioned power supply device may be a device capable of outputting voltage to the outside, such as a fast charging (PD) charger, and the like, and is not limited herein.

The smart cradle further includes a communication chip, which may be an electronic MARK chip (E-MARK IC) or a single bus communication IC chip, and is mainly used for data communication with a terminal, and is not limited specifically.

In the embodiment of the application, when the power supply equipment is connected into the intelligent support through the second interface, the power supply equipment can output power voltage, so that power can be supplied to the terminal. The line used by the power supply device for supplying power to the terminal may be directly supplied with power through a power line between the second interface and the first interface. The purpose of supplying power to the terminal by the power supply equipment is to enable the terminal to output an access signal to the communication chip, and further serve as a precondition for the terminal to actively initiate access to the communication chip.

Since the communication chip has stored therein the related information of the smart stent, such as: therefore, after the communication chip receives the access signal sent by the terminal, the communication chip can obtain the ID information of the intelligent support according to the access signal and feed the ID information back to the terminal, so that the terminal can obtain the ID information, where the ID information identifies the identity information of the corresponding intelligent support, such as: manufacturer Identity (ID) information (Vendor identity: Vendor ID), Product Identity (ID) information (Product identity: Product ID), and the like can identify the identity information of the intelligent support, and the specific details are not limited herein. Thus, when the ID information matches the preset identification information, the terminal can recognize that the cradle is not normally related to but only has a supporting function, but can enter an intelligent cradle of a certain working mode, and can start a target mode, such as: the method can be a working mode of automatically calling the first installation package APK or automatically calling the first application program and the like; or may automatically invoke a voice assistant. It should be noted that the first application mentioned above may be an APP such as a WeChat, a video player, a camera, and the like, and is not limited specifically.

For example: assuming that the starting target mode is to automatically call the voice assistant, when the terminal determines that the ID information of the smart stent matches the preset identification information, and the preset identification information corresponds to the voice assistant in a related manner, the terminal will automatically call the voice assistant, so that the installed software can be controlled to be started through a voice instruction.

If the terminal determines that the ID information of the intelligent support is matched with the preset identification information, the terminal automatically starts a predefined operation, and the preset identification information and the WeChat APP are associated in the predefined operation, so that the terminal can automatically call the target mode of the WeChat APP; otherwise, if the terminal does not match the ID information with the preset identification information, it will not start the operation, and will not automatically call the mode of the WeChat APP naturally. Therefore, when the ID information is matched with the preset identification information, the terminal can automatically call the target mode associated with the intelligent support, and the mode starting efficiency is improved.

Fig. 2b is a terminal interface display diagram provided in the embodiment of the present application.

Optionally, on the basis of the embodiment corresponding to fig. 2a, as shown in fig. 2b, the power supply device is connected to the intelligent support, and the intelligent support is connected to the terminal, and if the preset operation set by the terminal is that the wechat APP is associated with the intelligent support, it can be seen from an interface of the terminal that the terminal can automatically call the wechat after the terminal is connected to the intelligent support.

In the embodiment of the application, the communication chip 203 acquires and feeds back the ID information of the intelligent support through the access signal of the receiving terminal, so that the terminal can automatically start a target mode only by communication between the communication chip and the terminal, communication with power supply equipment is not needed, the circuit structure of the intelligent support is simplified, the cost is reduced, and the mode starting efficiency is improved.

In this technical solution, for different communication chips, the internal circuit structure of the smart bracket is also different, so in this embodiment of the present application, the structure of the smart bracket is described by taking two different types of chips as an example.

Two different types of chips are described in the embodiments of the present application, one that is operable when power is supplied to the chip by a power supply device, and one that is operable when power is not supplied to the chip by a power supply device.

First, embodiments of the present application are described with reference to fig. 3 to 5, in relation to an intelligent cradle using a chip that needs a power supply device to supply power to the intelligent cradle.

Fig. 3 is another schematic structural diagram of an intelligent support provided in an embodiment of the present application.

Optionally, on the basis of the embodiment corresponding to fig. 2a, as shown in fig. 3, another embodiment of the smart bracket provided in the embodiment of the present application may further include: the voltage regulator 301 and the communication chip 203 include a first chip 2031, the first interface module 201 includes a first pin 2011, one end of the voltage regulator 301 is connected to the second interface 202, the other end of the voltage regulator is connected to the first chip 2031, and the first chip 2031 is connected to the first pin 2011.

When the power supply apparatus accesses the second interface 202, the first chip 2031 is powered by the voltage regulator 301.

The first chip 2031 receives an access signal sent by the terminal through the first pin 2011.

In this embodiment, based on the embodiment described in fig. 2a, when the power supply device accesses the smart cradle through the second interface, the output power voltage may be adjusted to a stable voltage suitable for the first chip 2031 to start operating through the voltage regulator, such as: 3.3V, which is not limited herein, the first chip 2031 is powered on after receiving power supply from the power supply device, so that the powered first chip 2031 can receive an access signal sent by the terminal through the first pin while the power supply device is powering the terminal, and as described in fig. 2a, the access signal terminal is actively sent to the first chip 2031 to request and acquire ID information of the smart cradle. Therefore, the terminal can automatically call the target mode only by communication between the first chip and the terminal, the mode starting efficiency is improved, the intelligent support does not need to communicate with the power supply equipment, the circuit structure of the intelligent support is simplified, and the cost is reduced.

In this embodiment, the voltage regulator may be a voltage regulator tube, a linear regulator (LDO), or other components similar to those used for voltage regulation, and is not limited herein.

Fig. 4 is another schematic structural diagram of an intelligent support provided in an embodiment of the present application.

Optionally, on the basis of the embodiment corresponding to fig. 3, as shown in fig. 4, another embodiment of the smart bracket provided in the embodiment of the present application may further include: a first pull-up resistor 401 and a second pull-up resistor 402, the first interface 201 further comprising a second pin 2012.

The first pin 2011 is connected to the power supply line described in fig. 2a through a first pull-up resistor 401, so that the terminal detects a first voltage between the first pin 2011 and the power supply line, and the second pin 2012 is connected to the power supply line described in fig. 2a through a second pull-up resistor 402, so that the terminal detects a second voltage between the second pin 2012 and the power supply line.

The first chip 2031 receives an access signal sent by the terminal through the first pin 2011 when the terminal determines that the first voltage and the second voltage both reach the target voltage.

In this embodiment, the first pin is connected to the power supply line described in fig. 2a through the first pull-up resistor, and the power supply line is a line through which the power supply device is connected to the intelligent rack and supplies power to the terminal through the power line between the second interface and the first interface, so that when the power supply device outputs a power voltage and supplies power to the terminal through the power supply line, the terminal can detect a voltage between the first pin and the power supply line, that is, the first voltage mentioned above, because the first pull-up resistor has a voltage division function. Usually, the first pull-up resistor has a resistance of 22kohm (kohm: kiloohm), and there may be other resistance values with more similar functions in practical applications, and the resistance is not limited herein. Similarly, the second pin is connected to the power supply line described in fig. 2a through the second pull-up resistor, so that while the power supply device outputs the power supply voltage and supplies power to the terminal through the power supply line, the terminal can detect the voltage between the second pin and the power supply line, that is, the second voltage mentioned above, because the second pull-up resistor also has the function of voltage division. Usually, the resistance of the second pull-up resistor is also 22kohm, and in practical applications, other resistance values with more similar functions may exist, and are not limited herein.

Therefore, after the terminal detects the first voltage and the second voltage, it needs to determine and determine whether the detected first voltage and the detected second voltage both reach the target voltage, such as: 1.5V, and is not particularly limited herein. The main purpose of doing so is to firstly carry out an initial judgment on whether the intelligent support is connected with the terminal, and if the terminal detects that both the first voltage and the second voltage reach the target voltage, the terminal is indicated to be accessed by the intelligent support which can be used for starting the associated target mode; on the contrary, if the terminal detects that both the first voltage and the second voltage do not reach the target voltage, it indicates that the terminal may be connected to a common peripheral bracket, such as: an earphone, etc., and is not particularly limited.

Since the first chip 2031 is connected to the first pin in the first interface, when the terminal accesses the smart bracket through the first interface, the connection between the first pin and the first chip 2031 forms a link for data communication between the first chip 2031 and the terminal.

On the basis of the embodiment corresponding to fig. 3, the first chip 2031 may start to operate after receiving power supply from the power supply device through the voltage regulator, so that when the terminal determines that both the first voltage and the second voltage reach the target voltage, the first chip 2031 in the operating state may receive an access signal sent by the terminal through the first pin while the power supply device supplies power to the terminal, where the access signal is actively sent to the first chip 2031 by the terminal after determining that the terminal is connected to the smart cradle, and is used to request and acquire ID information of the smart cradle.

Since the first chip 2031 has stored therein the information related to the smart cradle, such as: ID information, data transmission capability information, and the like, so that after the first chip 2031 receives an access signal sent by the terminal, the ID information of the smart cradle can be extracted according to the access signal and fed back to the terminal, so that the terminal can acquire the ID information, where the ID information identifies the identity information of the corresponding smart cradle, and therefore the terminal can recognize, according to the ID information, that the cradle is not a cradle that is usually involved and has only a supporting function, but can enter a smart cradle in a certain operating mode, which is understood with reference to the scene diagram described in fig. 2 b. Therefore, the terminal can automatically call the target mode only by communication between the first chip and the terminal, the mode starting efficiency is improved, the intelligent support does not need to communicate with the power supply equipment, the circuit structure of the intelligent support is simplified, and the cost is reduced.

The first pin and the second pin in the first interface in fig. 3-4 may be CC pins, i.e., CC1_ U and CC2_ U, which enable signals to be transmitted between the first chip and the terminal.

Fig. 5 is another schematic structural diagram of an intelligent bracket provided in an embodiment of the present application.

Optionally, on the basis of the embodiment corresponding to fig. 4, as shown in fig. 5, another embodiment of the smart bracket provided in the embodiment of the present application may further include a first pull-down resistor 501 and a second pull-down resistor 502, and the second interface 202 includes a third pin 2021 and a fourth pin 2022.

The third pin 2021 is grounded through the first pull-down resistor 501, and the fourth pin 2022 is grounded through the second pull-down resistor 5022, so that the power supply apparatus outputs a voltage.

In this embodiment, when the power supply device is connected to the second interface, the power supply device can output a voltage and supply power to the terminal through the power supply line shown in fig. 2a, fig. 3, and fig. 4, and supply power to the first chip 2031 through the voltage regulator shown in fig. 3, so that the third pin and the fourth pin of the second interface need to be grounded through the first pull-down resistor and the second pull-down resistor, respectively, so that the power supply device can recognize a low level after the third pin and the fourth pin are grounded, thereby outputting a power supply voltage, and eliminating a high impedance input. Usually, the resistance of the first pull-down resistor and the resistance of the second pull-down resistor are 5.1kohm, and in practical applications, there may be other resistance values with more similar functions, which is not limited herein.

It should be noted that, in this embodiment, the third pin and the fourth pin in the second interface may be CC pins, that is, CC1_ D and CC2_ D, which enable the power supply device to configure the power supply voltage Vbus.

It should be noted that, since the first chip 2031 and the first interface and the second interface described in fig. 2a, fig. 3 and fig. 4 do not store electric energy inside the first chip 2031, a power supply device is required to supply power to the first chip 2031, which may be an E-MARK IC chip or a chip similar to the E-MARK IC chip for data communication with a terminal, and the embodiment is not limited in this embodiment; the first interface and the second interface are mainly TPYE-C interfaces, but there are many similar interfaces in practical application, and the embodiment of the present application is not limited.

Second, for an intelligent cradle using a chip that can operate without power supply from a power supply device, the embodiments of the present application are described with reference to fig. 6 to 7.

Fig. 6 is another schematic structural diagram of an intelligent bracket provided in an embodiment of the present application.

Optionally, on the basis of the embodiment corresponding to fig. 2a, as shown in fig. 6, another embodiment of the smart bracket provided in the embodiment of the present application may further include: the communication chip 203 includes a second chip 2032, the first interface 201 includes an identification ID pin 2013; the ID pin 2013 is connected to the second chip 2032.

When the power supply apparatus supplies power to the terminal, the second chip 2032 receives an access signal transmitted from the terminal through the ID pin 2013.

In this embodiment, since the second chip 2032 is connected to the ID pin of the first interface, when the terminal is connected to the smart shelf through the first interface, the connection between the ID pin and the second chip 2032 forms a link for data communication between the second chip 2032 and the terminal.

Therefore, when the power supply device supplies power to the terminal through the power supply line as described in fig. 2a, the second chip 2032 may receive an access signal sent by the terminal through the ID pin while the power supply device supplies power to the terminal, so that the terminal may request and acquire the ID information of the smart shelf.

Since the second chip 2032 has stored therein the information related to the smart stent, such as: ID information, data transmission capability, and the like, so that after the second chip 2032 receives an access signal sent by a terminal, the second chip 2032 can extract the ID information of the smart rack according to the access signal and feed the ID information back to the terminal, so that the terminal can acquire the ID information, where the ID information identifies the identity information of the corresponding smart rack, and therefore the terminal can recognize, according to the ID information, that the smart rack is not a commonly related rack with only a supporting function, but can enter a certain operating mode, which is understood with reference to the scene diagram described in fig. 2 b. Therefore, the terminal can automatically call the target mode only by communication between the second chip and the terminal, the mode starting efficiency is improved, the intelligent support does not need to communicate with the power supply equipment, the circuit structure of the intelligent support is simplified, and the cost is reduced.

Fig. 7 is another schematic structural diagram of an intelligent support provided in an embodiment of the present application.

Optionally, on the basis of the embodiment corresponding to fig. 6, as shown in fig. 7, another embodiment of the smart bracket provided in the embodiment of the present application may further include: the first interface 201 further includes a GND pin 2014, the GND pin 2014 is connected to the terminal chip, and the ID pin 2013 is further used for connecting the terminal chip, so that the terminal chip detects a voltage between the ID pin 2013 and the GND pin 2014.

The second chip 2032 receives an access signal sent from the terminal through the ID pin 2013 when the chip of the terminal detects that the voltage between the ID pin 2013 and the GND pin 2014 reaches the target voltage.

In this embodiment, since the ID pin and the GND pin of the first interface are both connected to a chip in the terminal, such as a soc chip, the chip of the terminal can detect a voltage interval between the two pins, i.e., the ID pin and the GND pin. Therefore, if the chip of the terminal detects the voltage interval between the two pins, i.e., the ID pin and the GND pin, the chip of the terminal needs to determine and determine whether the detected voltage interval between the two pins, i.e., the ID pin and the GND pin, reaches the target voltage, such as: 1.5V-1.7V, and is not particularly limited herein. The main purpose of doing so is to firstly carry out an initial judgment on whether the intelligent support is connected with the terminal, and if a chip of the terminal detects that the voltage between two pins, namely an ID pin and a GND pin, reaches a target voltage, the terminal is connected with the intelligent support which can be used for starting a related target mode; on the contrary, if the chip of the terminal detects that the voltage between the two pins, i.e. the ID pin and the GND pin, does not reach the target voltage, it indicates that the terminal may be connected to a common peripheral bracket, such as: earphones, vehicle-mounted equipment, VR helmets and the like, and are not particularly limited.

Therefore, when the chip of the terminal determines that the voltage interval between the two pins, i.e., the ID pin and the GND pin, reaches the target voltage, the second chip 2032 may receive an access signal sent by the terminal through the ID pin while the power supply device supplies power to the terminal, where the access signal is actively sent to the second chip 2032 by the terminal after determining that the terminal is connected to the smart cradle, so as to request and acquire the ID information of the smart cradle, which can be understood with reference to fig. 6. Therefore, the terminal can automatically call the target mode only by communication between the second chip and the terminal, the mode starting efficiency is improved, the intelligent support does not need to communicate with the power supply equipment, the circuit structure of the intelligent support is simplified, and the cost is reduced.

The second chip 2032 and the first interface and the second interface described in fig. 6 and fig. 7 are to be described, because the second chip 2032 stores power, the second chip 2032 does not need to receive power supply, and may be a single-bus communication IC chip or a chip similar to the single-bus communication IC chip, which is used for data communication with a terminal and does not need to receive power supply, and the embodiment of the present application is not limited thereto; the first interface and the second interface are mainly MICRO USB interfaces, but in practical applications, the embodiments of the present application are not limited.

The embodiment described above in fig. 2a to fig. 7 is a schematic structural diagram of the smart rack of the present embodiment, and the mode starting method is described in detail below by way of the embodiment.

Fig. 8 is a schematic diagram of an embodiment of a method for mode startup provided by an embodiment of the present application.

As shown in fig. 8, a method for mode startup provided in an embodiment of the present application may include:

801. when the power supply equipment supplies power to the terminal through the power supply line between the second interface and the first interface, the terminal sends an access signal to the communication chip through the first interface.

In this embodiment, the access signal may be used to obtain the identification ID information of the smart stent. If the power supply equipment is connected to the intelligent support through the second interface, the first output power supply voltage can provide electric quantity for the terminal along a power supply line between the second interface and the first interface, and the electric quantity can be used as an initial condition that the terminal can access the communication chip in the intelligent support. In order to enable the terminal to quickly and correctly start the target mode associated with the smart rack, the terminal must accurately identify the smart rack in the connected general external device, and the communication chip stores relevant information of the smart rack, such as: ID information, data transmission capability information, and the like, so that the terminal can initiate an access signal to the communication chip through the first interface to obtain the ID information of the smart bracket, such as: manufacturer identification ID information (Vendor ID: Vendor ID), Product identification ID information (Product ID: Product ID), and the details are not limited herein.

804. And the terminal judges whether the ID information of the intelligent support is matched with the preset identification information.

In this embodiment, the terminal side has pre-stored preset identification information for identifying the smart stent, and the preset identification information is associated with the target mode, for example: identity information. Therefore, after the terminal receives the ID information of the smart bracket fed back by the communication chip, the ID information needs to be matched with the preset identification information, so as to improve the accuracy of starting the target mode.

It should be noted that the first application mentioned above may be an APP such as a WeChat, a video player, a camera, and the like, and is not limited specifically.

For example: assuming that the target mode is a voice assistant, when the terminal determines that the ID information of the smart rack matches the preset identification information, and the preset identification information corresponds to the voice assistant in a related manner, the terminal will automatically invoke the voice assistant, so that the installed software can be controlled to be started through a voice instruction.

If the terminal determines that the ID information of the intelligent support is matched with the preset identification information, the terminal automatically starts a predefined operation, and the preset identification information is associated with the WeChat APP in the predefined operation, so that the terminal can automatically call the target mode of the WeChat APP; otherwise, if the terminal does not match the ID information with the preset identification information, it will not start the operation, and will not automatically call the mode of the WeChat APP naturally. Therefore, when the ID information is matched with the preset identification information, the terminal can automatically call the target mode associated with the intelligent support, and the mode starting efficiency is improved.

In this embodiment, on the basis of having simplified the circuit structure of intelligent support, the intelligent support only need communicate with the terminal to make the terminal can start the target mode after confirming that the ID information of intelligent support matches with preset identification information, promoted the efficiency of mode start effectively.
