Description
Technical Field
The present invention relates to an electronic device and a method for controlling a signal source thereof, and more particularly, to an electronic device capable of being connected to a mobile terminal and a method for controlling a signal source thereof.
Background
In recent years, a technology for connecting an electronic device such as an in-vehicle device to a mobile terminal such as a smart phone is known. For example, as shown in fig. 1, the mobile terminal 2 is connected to the electronic apparatus 1 having a touch display screen by MirrorLink (registered trademark) standard, so that a screen displayed on the mobile terminal 2 can be displayed on the touch display screen of the electronic apparatus 1 at the same time. Further, the user may click on a screen (icon or the like) on the touch display screen of the operation electronic apparatus 1 to operate and control the mobile terminal 2, for example, to start running an application program or the like in the mobile terminal 2.
In addition, with the increase of the demands of users for functions such as internet of vehicles (Internet of Vehicles) and mobile interconnection, and the rapid development of mobile terminal technologies such as smartphones and the increasing of functions, recently, automobile enterprises and internet enterprises have developed new connection standards such as CarPlay (registered trademark) and CarLife (registered trademark), and the mobile terminals and electronic devices can be more conveniently connected by these new connection standards. These new connection standards set an application installed in a mobile terminal as a virtual function option in an electronic device through a protocol between the mobile terminal and the electronic device, and an icon represented by the application can be displayed in the electronic device.
In the case of the connection established by the new connection standard, when the icon represented by the application program at the electronic device side is clicked, the coordinate position information of the icon is sent to the mobile terminal, but the electronic device side cannot know what application program is executed, on the other hand, the mobile terminal executes the corresponding application program after receiving the coordinate position information, and sends the display picture information of the application program to the electronic device, and the electronic device displays the picture information, but cannot know what application program is displayed. It is only possible for the electronic device to know whether the currently operating signal source is from the electronic device itself or from the mobile terminal.
For example, the electronic device currently operates its own radio signal source, and if the user clicks an icon of an application iPod (registered trademark) of the mobile terminal, the radio signal source is switched to the iPod signal source of the mobile terminal, but after that, if the user clicks another application such as Pandora (registered trademark) of the mobile terminal, the mobile terminal switches the iPod to Pandora and sends the picture information of Pandora to the electronic device for display, but the electronic device cannot distinguish between the signal sources from the mobile terminal for both the iPod and Pandora, so that the switching of the signal sources is not performed. If an interrupt signal such as a telephone or a reverse image occurs at this time, after the interrupt signal is ended, the electronic device automatically returns to the signal source before the interrupt signal occurs, that is, to the iPod signal source by default. Thus, it is very confusing for the user to listen to Pandora before the interrupt signal occurs, and why the interrupt signal returns to the iPod that has been previously switched after the end. In addition, if the user is to continue to listen to the Pandora, the user also has to perform operation again to switch the iPod to the Pandora, so that the operation amount of the user is greatly increased, the operation time of the user is wasted, great trouble is brought to the user, and meanwhile, the application convenience of the electronic device is reduced.
Disclosure of Invention
The present invention has been made in view of the above-described problems, and an object thereof is to provide an electronic device capable of switching signal sources in good time and a control method of the signal sources.
An electronic device of the present invention includes: a connection unit which connects to a mobile terminal capable of installing a plurality of application programs; a receiving unit that receives, from the mobile terminal, information of an application program that the mobile terminal is running; a detection unit that detects a signal source currently running in the electronic device; and the control part is used for switching the signal source currently running to the signal source to which the application program currently running of the mobile terminal belongs when the judging part judges that the application program currently running of the mobile terminal does not belong to the signal source currently running.
According to the electronic device, when the application program which is running on the mobile terminal does not belong to the signal source which is running on the electronic device, the signal source which the application program belongs to is used as the signal source which is running on the electronic device, so that even if an interrupt signal occurs, the electronic device terminal can automatically return to the signal source before the interrupt signal occurs after the interrupt signal is ended, a user does not need to perform switching operation, the operation time is saved, meanwhile, the confusion of the user on the application program which is not returned to the application program which is running before the interrupt signal occurs is eliminated, and the application convenience of the electronic device is improved.
In the electronic device according to the present invention, the electronic device may further include a specification unit that specifies an application program installed in the mobile terminal, and the control unit may control the reception unit to receive information of the application program when the application program specified by the specification unit is running. Therefore, information can be received only for the appointed application program, unnecessary processing execution and processing time are saved, the effective processing efficiency of the electronic device is greatly improved, meanwhile, the processing operation space is saved, and the operation speed of the electronic device is also greatly improved.
The electronic device of the present invention may further include a storage unit that stores signal source information to which an application program installed in the mobile terminal belongs. Thus, when the receiving part receives the application program information of the running mobile terminal, the receiving part can directly correspondingly extract the signal source information of the running mobile terminal from the storage part, and then the signal source information is compared with the signal source of the running electronic device through the judging part to judge whether the signal source belongs to the signal source of the running electronic device. Therefore, the judging speed can be greatly improved, the processing efficiency of the electronic device can be improved, and whether the signal source of the electronic device running currently is switched to the signal source of the application program of the mobile terminal running currently can be rapidly judged.
The electronic device of the present invention may further include an interrupt signal detection unit that detects the interrupt signal, and the control unit may control the return to the signal source before the interrupt signal is generated after the interrupt signal is completed. Therefore, after the interrupt signal detection part detects that the interrupt signal is finished, the signal source before the interrupt signal is generated is returned, so that the user can continue to apply the signal source, the user is not required to perform signal source switching operation, the operation time is saved, and meanwhile, the confusion of the user on the application program which is not returned to the interrupt signal and is running before the interrupt signal is generated is eliminated.
The electronic device of the present invention may further include a presentation unit that presents the currently running signal source information. Therefore, after the interrupt signal is ended, the electronic device returns to the signal source before the interrupt signal occurs, and at the moment, the information of the signal source which is currently running is prompted, so that the user can know the information of the signal source which is currently running more clearly, and the confusion of the user can be better eliminated.
In order to solve the above problems, the present invention also provides a method for controlling a signal source, comprising: a connection step of connecting with a mobile terminal capable of installing a plurality of application programs; a receiving step of receiving information of an application program being run by the mobile terminal from the mobile terminal; a detection step of detecting a signal source currently running in the electronic device; and a judging step of judging whether the application program running on the mobile terminal received by the receiving step belongs to the signal source running on the current detected by the detecting step, and a control step of switching the signal source running on the current to the signal source to which the application program running on the mobile terminal belongs when the judging step judges that the application program running on the mobile terminal does not belong to the signal source running on the current.
According to the electronic device and the control method of the signal source thereof, when the application program of the running mobile terminal does not belong to the signal source of the running electronic device, the control part takes the signal source of the application program as the signal source of the running electronic device, so that even if an interrupt signal occurs, the electronic device terminal can automatically return to the signal source before the interrupt signal occurs after the interrupt signal is ended, the user does not need to perform switching operation, the operation time is saved, and meanwhile, the confusion of the user on the application program which is not returned to the running electronic device before the interrupt signal occurs is eliminated, and the application convenience of the electronic device is improved.

Detailed Description
Hereinafter, preferred embodiments of the electronic device according to the present invention will be described in detail with reference to the accompanying drawings.
Fig. 2 is a block diagram showing the configuration of an electronic device according to an embodiment of the present invention. As shown in the figure, the electronic device 1 of the present embodiment includes: a connection unit 10, a receiving unit 11, a detecting unit 12, a judging unit 13, a display unit 14, and a control unit 15.
The connection unit 10 is composed of a dedicated communication module having a communication function, and connects the electronic device 1 and the mobile terminal 2 according to a communication protocol. Taking Wi-Fi (wireless-fidelity) as an example, the electronic device 1 and the mobile terminal 2 which acquire the wireless network protocol are connected to each other, and a relationship in which data are connected to each other is established. Similarly, a short-range wireless communication protocol such as Bluetooth (registered trademark) or ZigBee (registered trademark) may be used, or a connection relationship may be established by a wired communication system such as USB.
Here, the connection operation of the connection unit 10 may be performed by the user's own operation, by starting a connection function to complete connection with the specific mobile terminal 2, or may be set in advance, and when a specific mobile terminal signal is detected, matching may be automatically performed to complete establishment of a connection relationship.
The receiving unit 11 is composed of a communication module, similar to the connecting unit 10, and receives information from the mobile terminal 2 after the connecting unit 10 completes connection with the mobile terminal 2. In the present embodiment, the receiving unit 11 receives information of an application program being executed by the mobile terminal 2, and includes: attribute information such as application name or ID (IDentity).
The detection unit 12 is constituted by an application specific integrated circuit or a CPU functional module, and detects a signal source currently operating the electronic device 1. The detection unit 12 of the present embodiment detects information such as the name or ID of the currently running signal source based on the attribute information of the currently running signal source.
The determination unit 13 is also constituted by an application specific integrated circuit or a CPU functional module, similar to the detection unit 12, and determines whether or not the application currently running in the mobile terminal 2 received by the reception unit 11 belongs to the signal source currently running detected by the detection unit 12. In the present embodiment, the determination unit 13 determines whether or not the name or ID information of the application currently running in the mobile terminal 2 matches the name or ID information of the signal source currently running in the electronic apparatus 1. When the names or the ID information of the two information are inconsistent, the application program running on the mobile terminal 2 is judged not to belong to the signal source currently running on the electronic device 1, and when the names or the ID information of the two information are consistent, the application program running on the mobile terminal 2 is judged to belong to the signal source currently running on the electronic device 1.
The display unit 14 also has the function of an operation unit (not shown), and includes a display and a touch panel. The display may be formed of a display device such as a liquid crystal LCD (Liquid Crystal Display), an organic EL (Electro-Luminescence Panel), or a plasma screen, and as shown in fig. 1, a display screen or the like transmitted from the mobile terminal 2 may be displayed.
Here, the touch panel of the display unit 14 may be any one of a capacitive type, a resistive type, an infrared type, a load detection type, and the like. The option to be operated is clicked on the display by a finger, a stylus, or the like, and is manipulated. As shown in fig. 1, the mobile terminal 2 may be operated by clicking a touch screen of the electronic device 1.
In the present invention, the display unit 14 may be provided with only a display without providing a touch panel, and the operation unit may be provided separately. The display unit 14 is not an essential feature of the present invention.
The control unit 15 is composed of a general computer, and has a bus (not shown) for connecting these components, for example, CPU, ROM, EEPROM, ROM, I/O. When the judging section 13 judges that the application program being operated by the mobile terminal 2 does not belong to the signal source to which the application program being operated by the electronic apparatus 1 belongs, the control section 15 switches the signal source to which the application program being operated by the mobile terminal 2 belongs to the signal source to which the electronic apparatus 1 is currently operated.
Next, a specific processing method will be described in detail with reference to fig. 3, taking the electronic device 1 of the present embodiment as an in-vehicle device and the connected mobile terminal 2 as a smart phone as an example.
First, whether or not the in-vehicle device is connected to the smart phone is detected by the connection unit 10 (step S101). The connection unit 10 of the present embodiment determines whether or not the in-vehicle device is connected to the smartphone by whether or not the signal/data of the smartphone is received (yes in step S101), and when the signal/data of the smartphone is received (yes in step S101), the process proceeds to step S102, otherwise (no in step S101), the process returns to step S101, and the detection and determination are again performed.
In addition, in step S102, running application information is received from the smart phone. In the present embodiment, when the smartphone starts the application, the signal is transmitted to the in-vehicle device, and the in-vehicle device receives the signal by the receiving unit 11 (yes in step S102), and then proceeds to step S103, otherwise (no in step S102), returns to step S102, and re-detects the signal.
Here, the receiving unit 11 is in a state of receiving information in real time, and the receiving unit 11 can receive the signal of the running application program when the smart phone transmits the signal.
In the present embodiment, the application information received by the receiving unit 11 that the smart phone is running includes: display screen information and attribute information having an application name or ID.
Moreover, the smart phone may install a plurality of application programs by downloading according to the user's requirement, for example: music class applications, network social class applications, etc., may also have installed by default a plurality of commonly used applications at the time of shipment, such as: player class applications, search engine class applications, etc.
In step S103, the signal source in which the in-vehicle device is currently operating is detected by the detection unit 12. In the present embodiment, the detection unit 12 detects a signal of a signal source currently in operation, obtains attribute information of the signal source based on the signal, and includes: name or ID information of the signal source.
Here, the detection unit 12 may perform detection in real time or may perform detection at a predetermined time period.
In the present embodiment, the detecting unit 12 regards the newly detected signal source as the currently operating signal source, that is, the currently operating signal source may be changed.
In addition, after detecting the signal source currently running in the in-vehicle device in step S103, the flow proceeds to step S104, and the determination unit 13 determines whether or not the application currently running in the smart phone received by the receiving unit 11 belongs to the signal source currently running detected by the detecting unit 12. In the present embodiment, the determination unit 13 determines whether or not the name or ID of the application currently being operated by the smartphone matches the name or ID of the signal source currently being operated by the in-vehicle device, and if the name or ID matches (yes in step S104), the processing ends, otherwise (no in step S104), the processing proceeds to step S105.
Here, according to the default setting or the user setting, whether the name or ID information is consistent or not may be compared separately, or if both the name and the ID are consistent, it may be determined that the application program that the smart phone is running belongs to the signal source that the in-vehicle device is currently running.
In step S105, the control unit 15 switches the signal source to which the application program currently running on the in-vehicle device belongs to.
Fig. 4 is a block diagram of an electronic device 1 according to another embodiment of the present invention, and as shown in the drawing, the electronic device 1 includes all the elements shown in fig. 2, and further includes: a designating unit 16, a storage unit 17, an interrupt signal detecting unit 18, and a presenting unit 19.
The specification unit 16 specifies an application installed in the mobile terminal 2, and when the application specified by the specification unit 16 is running, the control unit 15 controls the reception unit 11 to receive information of the application.
Here, the specification unit 16 may specify an application program according to a protocol between the electronic device 1 and the mobile terminal 2, or may select an application program from among application programs in the mobile terminal 2 according to a user's own demand.
The storage unit 17 is configured by a nonvolatile memory such as a flash memory, a volatile memory such as RAM (Ramdom Access Memory), or a combination of both, and stores signal source information to which an application program installed in the mobile terminal 2 belongs. The storage unit 17 may store the source information to which a plurality of applications belong in advance, or may store the source information after the receiving unit 11 receives the application attribute information. In the present embodiment, the storage unit 17 stores names or ID information of a plurality of application programs.
The interrupt signal detection unit 18 detects an interrupt signal, and after the interrupt signal is completed, the control unit 15 controls the return to the signal source before the interrupt signal is generated.
Here, the interrupt signal is a signal set according to the electronic apparatus 1, for example: telephone signals, reverse image signals, etc., which have a higher priority than other signal sources, and when an interrupt signal occurs, the other signal sources perform a suspension process.
The presentation unit 19 presents the information of the signal source being operated, and particularly presents the signal source currently being operated by the electronic device 1 after the interrupt signal is completed. In the present embodiment, the presentation unit 19 may display the name of the currently operated signal source on the display unit 14, or may broadcast the name of the currently operated signal source to the user by voice through a speaker (not shown).
Next, a specific processing method of the electronic device 1 according to the present embodiment will be described in detail with reference to fig. 5. In the present embodiment, the electronic device 1 is exemplified by an in-vehicle device, and the mobile terminal 2 is exemplified by a tablet computer.
Step S201 is the same as step S101 in fig. 3, and a specific method for detecting whether the vehicle-mounted device is connected to the tablet pc is not described here.
In addition, in step S202, when the application designated by the designating unit 16 is started to run, the receiving unit 11 receives information of the application, and determines whether or not a plurality of pieces of application information in the tablet computer are received in succession, that is, whether or not there is a change in the running application, and when a plurality of pieces of running designated application information are received in succession (step S202
Yes, the process goes to step S203, otherwise (no in step S202), returns to step S202, and performs reception and judgment again.
Here, the receiving unit 11 is in a state of receiving information in real time, and receives more than 2 running signal source information in succession, and can determine that the running application is changed, and use the latest received application as the running application of the tablet computer.
In addition, step S203 is similar to step S103 in fig. 3, and the signal source that the vehicle-mounted device is currently operating is detected by the detecting unit 12, and the specific method is not described here.
In addition, after detecting the signal source currently running in the in-vehicle device in step S203, the process proceeds to step S204, and the determination unit 13 determines whether or not the application currently running in the tablet computer received by the receiving unit 11 belongs to the signal source currently running detected by the detecting unit 12. In the present embodiment, the determination unit 13 determines whether or not the application program newly received by the receiving unit 11 belongs to the currently running signal source detected by the detecting unit 12. In the present embodiment, the name or ID information of the application program is extracted from the storage unit 17, and compared with the name or ID of the signal source currently operated by the in-vehicle device, it is determined whether or not the information matches. When the names or IDs of the two are identical, that is, when the application program being run by the tablet computer belongs to the signal source currently being run by the in-vehicle machine (yes in step S204), the process proceeds to step S206, otherwise (no in step S204), the process proceeds to step S205.
In addition, step S205 is the same as step S105 in fig. 3, and the control unit 15 switches the signal source currently running in the vehicle-mounted device to the signal source to which the application program currently running in the tablet computer belongs, and the specific method is not described here.
In step S206, the interrupt signal detection unit 18 detects the interrupt signal, and when it is detected that the interrupt signal has occurred (yes in step S206), the routine proceeds to step S207, otherwise (no in step S206), the routine returns to step S206, and the detection is again performed.
In step S207, the interrupt signal detection unit 18 detects whether or not the interrupt signal is terminated. When the interrupt signal ends (yes in step S207), the routine proceeds to step S208, and if not (no in step S207), the routine returns to step S207, and the detection is resumed.
In step S208, the control unit 15 returns the control to the signal source before the interrupt signal is generated, that is, the signal source before the interrupt signal is generated as the signal source at which the in-vehicle device is currently operating.
Here, the presentation unit 19 may display the name information of the currently running signal source on the display unit 14, or may display the name information of the running application on the display unit 14.
Therefore, according to the electronic device and the control method of the signal source thereof, when the application program of the running mobile terminal does not belong to the signal source of the running electronic device, the control part takes the signal source of the application program as the signal source of the running electronic device, so that even if an interrupt signal occurs, the electronic device terminal can automatically return to the signal source before the interrupt signal occurs after the interrupt signal is ended, the user does not need to perform switching operation any more, the operation time is saved, and meanwhile, the confusion of the user on the application program which is not returned to the running electronic device before the interrupt signal occurs is eliminated, and the application convenience of the electronic device is improved.
The electronic device of the present invention is not limited to the vehicle-mounted device in the above embodiment, but is also applicable to all electronic devices that can be connected to a mobile terminal, such as a personal computer, a tablet pc, and a television.
