Portable electronic device, system control method of portable electronic device, and expandable electronic system

The present invention relates to portable electronic devices, and more particularly to a portable electronic device that can be combined with an expansion electronic device.

With the development of mobile terminals and mobile communication technologies, the use of mobile phones has become more and more popular. In addition to traditional mobile phones with voice communication capabilities, smart phones with access to the Internet and video transmission are more popular.

Traditional mobile phones have limited functions because of the small screen size, slow processing speed of the central processing unit (CPU), and small memory storage space, and the inability to execute operating systems such as Android or Windows Phone. Today's smart phones on the market have easy-to-use touch screens and a variety of functional modules, such as Wi-Fi modules, Bluetooth modules, etc., but also increase the processing load, making smart phones The power consumption is so large that it can't have a long (usually up to several days) standby time like a traditional mobile phone. In addition, unused applications (Applications) resident in the operating system of the smart phone consume power even if the user does not notice it. Although there is a system killer (Task killer) to help users clear unused applications, users must frequently manually remove the program by operating the system, increasing user inconvenience. For Wi-Fi modules, Bluetooth modules and other power-hungry hardware modules, users do not know how to control these hardware modules to reduce power consumption, and may even inadvertently open and not use them. The function module consumes power.

In addition, whether it is a traditional mobile phone or a smart phone, if some components are damaged, such as the screen is damaged, and it is not possible to replace the screen just like a personal computer, but the whole mobile phone needs to be replaced, and it is impossible to upgrade based on the hardware. To replace the hardware components that you want to upgrade, you need to replace the entire mobile phone, which not only saves money but also consumes resources.

Based on the fact that modern people often have more than one type of electronic device, many technologies are dedicated to integrating or combining multiple electronic devices to expand the application level, such as combining a smart phone with a tablet or connecting a smart phone through various multimedia interfaces. To an external device, for example, a smart phone is connected to an external screen by a High Definition Multimedia Interface (HDMI). However, in the case of combining a smart phone with a tablet, the above-mentioned power consumption problem also exists when the smart phone is used alone, and when the smart phone is combined with the tablet and used as a tablet, on the smart phone. Hardware components such as touch screens are not used and cost-effective. In the example of connecting a smart phone to an external screen through a high-definition multimedia interface, the external screen usually does not have a touch operation function, so that some application functions related to the touch operation cannot be used or reduced. The convenience of handling.

(For example, the above-mentioned mobile phone 20). When the mobile phone is powered on, it is preset to operate in the second mode (basic mode). When the mobile phone operates in the second mode, the central processing unit does not execute the control and processing procedures associated with the extended electronic device, and only executes Control and processing procedures related to portable electronic devices, such as conventional dial-up calls using GSM modules. In step S600, the sensor of the mobile phone, for example, the sensor 294, detects whether the mobile phone has a combined event or a disengagement event, and combines the event to combine the extended electronic device with the mobile phone, and the disengagement event is to expand the electronic device. The mobile phone that was originally combined. The use of sensors to detect the combination and disengagement of the expansion electronics is well known in the art and will not be repeated. In step S610 and step S620, it is determined whether there is a binding event or a detachment event according to the sensing signal of the sensor. If there is a binding event (step S610: YES), the representative mobile phone is combined with the extended electronic device, then in step S630, the central processing unit accesses data related to the extended electronic device, such as Wi-Fi connection, from the relevant memory. Data, Bluetooth connection data, etc., then in step S640, the central processing unit idles the second mode and enters the first mode (advance mode), controlling the mobile phone to operate in the first mode. When the central processing unit enters the first mode, the central processing unit performs control and processing procedures related to the extended electronic device according to the related data, in addition to executing the control and processing procedures related to the mobile phone, to expand the components of the electronic device and Control and operation of the function module, such as using touch screen output information, establishing Wi-Fi connection based on Wi-Fi connection data, and using Bluetooth module Communication, adjusting the display direction of the touch screen according to the sensing signal of the gravity sensor, and the like.

If there is a disengagement event (step S610: NO; step S620: YES), on behalf of the expansion electronic device is detached from the originally combined mobile phone, then in step S650, the central processing unit backs up the data related to the extended electronic device to Relevant memory is used for the next time when it is combined with an expansion electronic device, such as Wi-Fi connection data, Bluetooth connection data, and the like. Next, in step S660, the central processing unit idles the first mode, returns to the preset mode of the second mode, and enters the second mode. For example, the preset mode of the second mode is to turn off the advanced function modules such as the Wi-Fi module and the Bluetooth module. When the central processing unit enters the second mode, the central processing unit closes the control and processing procedures associated with the extended electronic device, and only performs control and processing procedures associated with the mobile phone for control and operation of the mobile phone.

If there is no binding event and there is no disengagement event (step S610: NO; step S620: NO), it is determined whether it is finished in step S670. For example, if the mobile phone wants to be turned off, the system control method ends (YES in step S670), otherwise The detector continuously monitors whether there is a binding event or a detachment event, and performs the corresponding steps when the next binding event or detachment event occurs.

In summary, according to the frequency of use of each component and function module, the degree of need, the degree of power consumption, etc., the components are arranged on the mobile phone or the extended electronic device, and are not in the mobile phone end as much as possible. The same function module is configured on the expansion electronic device side, so that the combination of the mobile phone and the expansion electronic device avoids the waste of cost and power due to the repeated use of one of the functional modules.
