Detailed Description
As described in the background art, in the prior art, a smart watch is waken up by touching a display screen or pressing a key to display time, and a main processor in the smart watch needs to be waken up, which results in large power consumption of the smart watch.
In order to solve the above problem, a control system of a smart watch provided in an embodiment of the present invention may include a main control subsystem, a sub-control subsystem, a display subsystem, and a switching module. When the intelligent watch is in a working state, the main control subsystem can obtain the control right of the display subsystem through the switching module so as to control the display subsystem. When the intelligent watch is in a dormant state, the secondary control subsystem can obtain the control right of the display subsystem through the switching module so as to control the display subsystem, and when the intelligent watch is in the dormant state, the primary control subsystem is in the dormant state. When the smart watch is in a dormant state, the main control subsystem is also in the dormant state, the display subsystem is controlled through the configured auxiliary control subsystem, and the main control subsystem and the subsystem which is not related to the display subsystem can be kept dormant in a user non-operation stage, so that the power consumption of the smart watch is reduced while the display subsystem still can keep simple information display capacity.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a schematic structural diagram of a control device of a smart watch according to an embodiment of the present invention is shown. The control device 1 of the smart watch may comprise a main control subsystem 11, a secondary control subsystem 12, a display subsystem 13 and a switching module 14.
In a particular implementation, a smart watch may include an active state and a sleep state. When the smart watch is in a working state, a user can operate the smart watch, and the main control subsystem 11 device can execute some application programs such as music and video playing. When the smart watch is in a dormant state, a user does not operate the smart watch, and except information displayed by a configured screen-off state of the smart watch, other subsystems are usually in the dormant state.
When the smart watch is in a working state, the main control subsystem 11 may obtain the control right of the display subsystem 13 through the switching module 14, so as to control the display subsystem 13. At this time, the information displayed by the display subsystem 13 mainly comes from the main control subsystem 11.
When the smart watch is in a sleep state, the secondary control subsystem 12 may obtain the control right of the display subsystem 13 through the switching module 14 to control the display subsystem 13, and at this time, the information displayed by the display subsystem 13 mainly comes from the secondary control subsystem 12. When the smart watch is in the sleep state, the main control subsystem 11 is in the sleep state.
In a specific implementation, the primary control subsystem 11 and the secondary control subsystem 12 may be communicatively coupled. The master control subsystem 11 and the secondary control subsystem 12 can transmit the state synchronization information. The intelligent watch can be awakened to enter a working state or indicated to be in a dormant state through the state synchronization information. It should be noted that even when the primary control subsystem 11 is in the sleep state, the data sent by the secondary control subsystem 12 can still be received through the preconfigured communication channel. Accordingly, when the main control subsystem 11 is in the working state, if the secondary control subsystem 12 does not enter the sleep state, the main control subsystem 11 may receive data sent by the secondary control subsystem 12.
When the main control subsystem 11 is in a working state, the sub-control subsystem 12 may be in a working state or a sleeping state, and may be configured specifically according to a requirement.
In some embodiments, the master control subsystem 11 and the secondary control subsystem 12 may transmit the state synchronization information through a state synchronization channel. The state synchronization may include various forms, which are not limited herein, and only needs to implement data transmission before the primary control subsystem 11 and the secondary control subsystem 12.
In some non-limiting embodiments, the switching device may be an access Matrix (Matrix) or a device capable of switching the control right of the display subsystem 13.
In an implementation, the main control subsystem 11 and the sub-control subsystem 12 are each configured with a corresponding processor, and are respectively used for controlling some corresponding functional subsystems. The host subsystem 11 is generally configured to perform complex multimedia system applications and is capable of responding fully to user actions and even executing complex application programs. The secondary control subsystem 12 is configured to Display an Always On Display (AOD) of a message screen when the smart watch is in the sleep state when the primary control subsystem 11 enters the sleep state. Usually, the main frequency, the memory consumption and the power consumption of the processor in the main control subsystem 11 are higher than those of the processor in the auxiliary control subsystem 12, so that when the smart watch is in a sleep state, the auxiliary control subsystem 12 controls the display of the display subsystem 13, and the power consumption of the smart watch can be reduced.
Therefore, when the smart watch is in a working state, the main control subsystem can obtain the control right of the display subsystem through the switching module to control the display subsystem. When the intelligent watch is in a dormant state, the secondary control subsystem can obtain the control right of the display subsystem through the switching module so as to control the display subsystem, and when the intelligent watch is in the dormant state, the primary control subsystem is in the dormant state. When the smart watch is in a dormant state, the main control subsystem is also in the dormant state, the display subsystem is controlled through the configured auxiliary control subsystem, the main control subsystem and the subsystem which is not related to the display subsystem can keep deep sleep in the stage that a user does not operate, and the power consumption of the smart watch is reduced while the display subsystem still can keep simple information display capacity.
In specific implementation, when the fact that the smart watch exits a user use scene and enters a screen-off state is detected, it can be judged that the smart watch enters a sleep state. When detecting that the smart watch enters the sleep state, the main control subsystem 11 sends first state synchronization information to the secondary control subsystem 12. The secondary control subsystem 12 may obtain control of the display subsystem 13 after receiving the first status synchronization message. The first state synchronization information is used to indicate that the smart watch is in a sleep state, so that the main control subsystem 11 can inform the secondary control subsystem 12 of the current state of the smart watch through the first state synchronization information, so as to inform that the secondary control subsystem 12 can prepare to take over the control right of the display subsystem 13.
In some embodiments, the master control subsystem 11 may enter the sleep state after sending the first state synchronization information to the secondary control subsystem 12. After receiving the first state synchronization information, the secondary control subsystem 12 may acquire the control right of the display subsystem 13 in a preemptive manner. After the secondary control subsystem 12 obtains control of the display subsystem 13, the primary control subsystem 11 no longer has control of the display subsystem 13.
In other embodiments, after the master subsystem 11 sends the first state synchronization information to the secondary subsystem 12, the secondary subsystem 12 may feed back the first response information to the master subsystem 11. The first response message is used to indicate that the secondary control subsystem 12 has received the first status synchronization message, and is used to inform the primary control subsystem 11 that it is ready to take over the control right of the display subsystem 13. After receiving the first response message, the main control subsystem 11 may enter a sleep state, or may release the control right of the display subsystem 13. After the sub-control subsystem 12 feeds back the first response information to the main control subsystem 11, the control right of the display subsystem 13 can be obtained.
In some embodiments, the control device 1 of the smart watch may further comprise a first memory module. The first storage module is connected with the secondary control subsystem 12 and is used for storing information to be displayed output by the secondary control subsystem 12. The display subsystem 13 may obtain the information to be displayed from the secondary control subsystem 12 and display the information. Specifically, the display subsystem 13 displays the information to be displayed on the display screen of the smart watch.
In some embodiments, the display subsystem 13 may acquire the information to be displayed from the first storage module in a Direct Memory Access (DMA) manner.
In some embodiments, the first storage module may employ a Static Random Access Memory (SRAM) or a Dynamic Random Access Memory (DRAM). It is understood that other types of dynamic memory may be used, as long as the data storage is enabled, and the description is not repeated here.
In a specific implementation, during the period when the smart watch is in the sleep state and the secondary control subsystem 12 takes over the control right of the display subsystem 13, the secondary control subsystem 12 may wake up from the sleep state periodically, and after the secondary control subsystem 12 wakes up from the sleep state periodically, the information to be displayed may be generated periodically. The secondary control subsystem 12 may enter the sleep state again after generating the information to be displayed.
In order to further reduce the power consumption of the smart watch, in the embodiment of the present invention, when the smart watch is in the sleep state, the secondary control subsystem 12 wakes up from the sleep state periodically, and combines preset pictures by using a preset combination logic to obtain the information to be displayed. The information to be displayed is obtained in the mode, the assistance of the main control subsystem 11 is not needed, the probability that the main control subsystem 11 is awakened is reduced, and the power consumption is further reduced.
In some embodiments, a timing module (timer) may be included in the secondary control subsystem 12, by which the secondary control subsystem 12 may be periodically awakened from a sleep state.
In specific implementation, the corresponding preset picture can be configured according to the information to be displayed. And the information to be displayed is different, and the configured preset images are different.
In some implementations, the information to be displayed may include time information. When the information to be displayed includes time information, the secondary control subsystem 12 may obtain the information to be displayed in the following manner.
Specifically, the default pictures are 10 digital pictures, which correspond to the numbers 0 to 9, respectively. The combinatorial logic is configured according to a temporal format. The secondary control subsystem 12 may determine the information to be displayed based on the time to take over the display subsystem 13 and the preconfigured time format.
In some embodiments, the time format is hh mm, where hh is hours and mm is minutes. In this time format, the time is updated every minute, corresponding to one picture every minute. Corresponding pictures can be selected from preset pictures to be combined to obtain the pictures corresponding to a period of time in the future, namely the information to be displayed. If the sub-control subsystem 12 takes over the control right of the display subsystem 13 at 12. The sleep time duration is configured to be 15 minutes, then the secondary control subsystem 12 may select a corresponding picture from preset pictures, and combine to obtain 15 pictures corresponding to 12.
In other embodiments, the time format is hh mm ss, where hh is hours, mm is minutes, and ss is seconds. In this time format, the time is updated every second, one picture per second. At this time, corresponding pictures can be selected from preset pictures to be combined, so that pictures corresponding to a period of time in the future, namely information to be displayed, can be obtained. If the sub-control subsystem 12 takes over the control right of the display subsystem 13 at 12. The sleep duration is configured to be 10 minutes, then the secondary control subsystem 12 may select a corresponding picture from preset pictures, and combine 600 pictures corresponding to 12.
The secondary control subsystem 12 inputs the generated multiple pictures into the first storage module according to a corresponding sequence, so that the display subsystem 13 can sequentially acquire the pictures corresponding to the time required to be displayed. When time 12.
For ": "corresponding pictures may be configured, and the preset pictures may further include symbol pictures, and when the information to be displayed is obtained by combination, the symbol pictures" may be obtained: "and the corresponding digital pictures.
For ": when the preset picture only includes a picture corresponding to a number, a mode of locally updating and combining the pictures, that is, only updating the number part, may be adopted.
In some embodiments, in order to increase the diversity demand of users, the information to be displayed may further include weather information and the like. When the information to be displayed includes weather information, corresponding weather information can be acquired when the smart watch enters the dormancy, and after the follow-up smart watch enters the dormancy, the acquired weather is used as a part of the information to be displayed, and only the time information and the like need to be locally updated.
It can be understood that the information to be displayed may also include other information, and the information may be configured specifically according to the requirement, which is not described herein again.
It should be noted that, in practical applications, other time formats or combinational logic may exist, and thus, other modified embodiments may exist on the basis of the above embodiments, and all of them are within the protection scope of the present invention.
In specific implementation, the sleep duration may also be other values, which are not illustrated one by one, and may be configured specifically according to requirements.
After the secondary control subsystem 12 outputs the information to be displayed to the first storage module, the sleep state is entered.
In specific implementation, the smart watch may be further configured with a plurality of touch sensors, and external status information may be monitored through the configured sensors. Several tactile sensors may be coupled as separate modules to the secondary control subsystem 12. Several tactile sensors may also be integrated into the secondary control subsystem 12. The number of sensors may include: proximity sensors, pulse sensors, acceleration sensors, temperature sensors, etc.
In some embodiments, the secondary control subsystem 12 may further obtain external status information, and when the obtained external status information satisfies a set condition, turn off the display subsystem 13, and enter a sleep state.
For example, the sub-control subsystem 12 turns off the display subsystem 13 and enters a sleep state when it determines that the smart watch is put in the pocket based on the external state information acquired from the proximity sensor.
For another example, the secondary control subsystem 12 may obtain acceleration information of the smart watch from the acceleration sensor to determine whether the smart watch is in a stationary state. After the smart watch is in a static state for a set period of time, the display subsystem 13 may be turned off and a sleep state may be entered. It is understood that, in order to improve the accuracy of determining whether the smart watch is in a stationary state, data collected by other sensors, such as a pulse sensor, may be combined. When the data indication acceleration that acceleration sensor gathered is 0, and the minute pulse number of beating of pulse sensor collection is 0, and lasts for a certain duration, then judges that the intelligent wrist-watch is in quiescent condition.
In addition, in order to further reduce the power consumption of the smart watch, in the embodiment of the present invention, the control device 1 of the smart watch may further include a second storage module and a third storage module.
In a specific implementation, when it is detected that the smart watch works in a first type of user usage scenario, the main control subsystem 11 outputs information to be displayed to the second storage module, so that the display subsystem 13 obtains the information to be displayed from the second storage module and displays the information. Wherein, the first kind of user usage scenario refers to an interactive scenario. Whether the scene belongs to the interactive scene can be judged according to whether user input data or input instructions are received or not. The first category of user usage scenarios may include game scenarios, phone scenarios, information scenarios, and the like.
In some embodiments, the second memory module may include a Double Data Rate (Double Data Rate) type memory to improve Data transfer rates and improve user experience. It will be appreciated that other types of memory may be employed.
In a specific implementation, when it is detected that the smart watch operates in a second class of user usage scenario, the main control subsystem 11 wakes up from a sleep state periodically, outputs information to be displayed to the third storage module, and enters the sleep state, so that the display subsystem 13 acquires the information to be displayed from the third storage module and displays the information.
Specifically, the main control subsystem 11 stores a large amount of information to be displayed in the third storage module at a time, then the main control subsystem 11 enters a sleep state, and the display subsystem 13 uses an internal timer system to acquire preset information to be displayed from the third storage module in a DMA manner at regular time to display the preset information. When the content is about to be exhausted, awakening the main control subsystem 11 to fill information to be displayed in the next period of time; or, the main control subsystem 11 is awakened periodically in a timed manner to fill the information to be displayed in the next period of time.
The second type of user usage scenario is a no interaction scenario. The scenario that some main control subsystems 11 output information to be displayed and can be realized without input data or input instructions of a user can be determined as a non-interactive scenario. The second type of user usage scenario may include video scenes, music scenes, and the like.
In a specific implementation, when the smart watch is in a sleep state, if the secondary control subsystem 12 receives a wake-up signal, second state synchronization information is sent to the primary control subsystem 11, where the second state synchronization information is used to wake up the primary control subsystem 11. When the main control subsystem 11 is awakened, the control right of the display subsystem 13 is switched to the main control subsystem 11.
In some embodiments, the wake-up signal may be generated when a user is detected to trigger a display screen of the smart watch, the user triggers a key on the smart watch, or the smart watch is detected to be lifted, etc.
In some embodiments, the secondary control subsystem 12 sends the second state synchronization information to the primary control subsystem 11, and after receiving the second state synchronization information, the primary control subsystem 11 may acquire the control right of the display subsystem 13 in a preemptive manner. After the primary control subsystem 11 obtains control of the display subsystem 13, the secondary control subsystem 12 no longer has control of the display subsystem 13.
In other embodiments, the secondary control subsystem 12 sends second state synchronization information to the primary control subsystem 11, and after the primary control subsystem 11 receives the second state synchronization information, the primary control subsystem 11 may feed back second response information to the secondary control subsystem 12. The second response message is used to indicate that the primary control subsystem 11 has received the second status synchronization message, and is used to inform the secondary control subsystem 12 that it is ready to take over the control right of the display subsystem 13. After the secondary control subsystem 12 receives the second response message, control of the display subsystem 13 may be released. After the main control subsystem 11 feeds back the second response information to the sub-control subsystem 12, the control right of the display subsystem 13 can be obtained.
In a specific implementation, any one of the main control subsystem 11 and the sub-control subsystem 12 in the above embodiments may be a corresponding chip.
In some non-limiting embodiments, the control device 1 of the smart watch may include a plurality of main control subsystems 11, sub-control subsystems 12, display subsystems 13, switching modules 14, and the like, which are independent of each other and connected. In some embodiments, the control device 1 of the smart watch may further include at least one of the first, second and third storage modules configured.
In other non-limiting embodiments, the main control subsystem 11, the sub-control subsystem 12, the display subsystem 13, the switching module 14, and the like may be packaged as a chip module, that is, the control device 1 of the smart watch is a chip module. In some embodiments, the chip module may further include a first memory module, a second memory module, a third memory module, and the like.
It should be noted that the first memory module and the third memory module may be two independent memory modules. The first storage module and the third storage module may also be the same storage module, and are respectively allocated to the secondary control subsystem 12 and the primary control subsystem 11 for use in a memory sharing manner.
An embodiment of the present invention further provides an intelligent watch, where the intelligent watch may include the control device of the intelligent watch provided in any one of the embodiments, and a working principle and a working flow of the control device of the intelligent watch may refer to descriptions in the embodiments of the present invention, and are not described herein again.
In order to better understand and implement the embodiments of the present invention, a control method for a smart watch is also provided in the embodiments of the present invention. The control method of the smart watch may control the smart watch provided in any of the above embodiments.
Referring to fig. 2, a flowchart of a control method of a smart watch in an embodiment of the present invention is shown, which may specifically include the following steps:
and S21, when the main control subsystem detects that the smart watch enters a dormant state, first state synchronization information is sent to the auxiliary control subsystem.
In specific implementation, when the fact that the smart watch exits a user use scene and enters a screen-off state is detected, it can be judged that the smart watch enters a sleep state. And when the master control subsystem detects that the smart watch enters a dormant state, first state synchronization information is sent to the secondary control subsystem. The first state synchronization information is used for indicating that the smart watch is in a dormant state, so that the main control subsystem can inform the secondary control subsystem of the current state of the smart watch through the first state synchronization information, and the secondary control subsystem can be informed of the control right of taking over the display subsystem.
And step S22, the secondary control subsystem acquires the control right of the display subsystem after receiving the first state synchronization information.
In some embodiments, the master subsystem may enter the sleep state after sending the first state synchronization information to the secondary subsystem. After receiving the first state synchronization information, the secondary control subsystem can acquire the control right of the display subsystem in a preemptive mode. After the sub-control subsystem acquires the control right of the display subsystem, the main control subsystem no longer has the control right of the display subsystem.
In other embodiments, after the master subsystem sends the first state synchronization information to the secondary subsystem, the secondary subsystem may feed back the first response information to the master subsystem. The first response information is used for representing that the sub-control subsystem has received the first state synchronization information and informing the main control subsystem that the main control subsystem is ready to take over the control right of the display subsystem. After receiving the first response message, the main control subsystem may enter a sleep state, or may release the control right of the display subsystem.
