Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
In this embodiment, the television device includes a device motherboard and a Power Management (PM) motherboard, where the device motherboard is a motherboard that operates when the television device operates normally, and may include devices such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and a Tuner. The power management mainboard is used for managing the power of the mainboard and monitoring the infrared power keys. The power management mainboard can monitor signals of a power key of the infrared remote controller when the television equipment is in a standby state.
When the television equipment is in a standby state, the power management mainboard is adopted to update the time information, so that when the television equipment is restarted, the system clock is updated according to the time information of the power management mainboard after the equipment mainboard is powered on, and the system clock can acquire time in time. Wherein, power-on refers to connecting a power supply to supply power.
Reference is made to the time processing diagram shown in figure 1.
When the television device works, the device motherboard of the television device can monitor the infrared signal to control the television device, if a signal of a power key on the infrared remote controller is received, a shutdown instruction can be correspondingly generated, in step 102, according to the shutdown instruction, the device motherboard acquires time information of a system clock, then sends the time information to the power management motherboard, and can transfer the control right of the infrared signal to the power management motherboard.
Then, in step 104, the device motherboard is powered off (as indicated by the dashed line in fig. 1), and the power management motherboard updates the time information and listens for the infrared signal. The power management motherboard can update the time information periodically through the timing device, for example, the counter updates the time information once, such as 1 second and 1 minute, when the update period is reached, and the power management motherboard determines that the update period is reached according to the crystal oscillator and updates the time information, wherein the update period can be set according to requirements. The crystal oscillator may be called a crystal oscillator, and may be timed by an oscillation frequency, a pulse signal, and the like, and determine the update period. Therefore, the timing device on the power management mainboard can update the time information and keep the accuracy of the time information.
The power management mainboard can also monitor the infrared signal of the remote controller and detect the awakening time based on the timing device when the television equipment needs to be awakened regularly. The timing wake-up function can set wake-up time for starting the television equipment, for example, the television equipment is started after one hour, and the television equipment is started at 9 am, so that the power management main board can detect whether the wake-up time is reached based on the timing device, for example, whether the wake-up time is reached is judged through an update cycle of the timing device, and whether the wake-up time is reached or not is judged based on the time information, for example, whether the wake-up time is reached or not is judged, and the like.
In step 106, the power management motherboard can generate a start instruction according to the set conditions, and send the start instruction to the device motherboard, and the device motherboard is powered on again and obtains the control right of the infrared signal.
The power management mainboard can generate a starting instruction after meeting the set conditions, wherein the set conditions comprise: and receiving a starting signal sent by a power key of the remote controller to achieve the awakening time. The power management mainboard can monitor infrared signals sent by the remote controller in real time, and if a starting signal sent by the power key is received, the power management mainboard can confirm that the set conditions are met and correspondingly generate a starting instruction. The shutdown instruction received by the device motherboard of the television device may also include timing wake-up information, for example, the shutdown instruction indicates to be turned off for one hour and then to be turned on, the corresponding power management motherboard may set the wake-up time, for example, for 1 hour, after the device motherboard is powered off, the power management motherboard further detects the wake-up time, and if the wake-up time is reached, it is determined that the set condition is satisfied, and a start instruction may be generated. Before the timing awakening function is set and the timing awakening time is not reached, if a starting signal sent by a power key is received, a starting instruction can be generated.
After the starting instruction is generated, the power management main board sends the starting instruction to the equipment main board, the equipment main board is electrified again and obtains the control right of the infrared signal, and then the equipment main board monitors the infrared signal of the remote controller.
And step 108, the equipment mainboard can obtain the time information after being started, and the time of the system clock is updated according to the time information. After the equipment mainboard is powered on again, the starting operation can be executed, and when the kernel of the equipment mainboard is started and the user space program can be started to be executed, the time information can be acquired from the power management mainboard.
Wherein, after the kernel of the device motherboard is started, obtaining updated time information from the power management motherboard includes: after the kernel of the equipment mainboard is started, running a communication program; and reading updated time information from the power management mainboard by adopting the communication program. After the kernel of the equipment mainboard is started, the operating system of the television equipment can start to execute the user space program, at the moment, a communication program can be operated, the communication program is adopted to communicate with the power management mainboard, the time information in the power management mainboard is read, and the time information is the time information for updating the power management mainboard. And then updating the time of a system clock in the operating system by using the updated time information, wherein the system clock can be set as the time corresponding to the time information.
In the embodiment of the application, a timing device of the power management main board may have a certain error, and the longer the time that the television device is in the standby state, the larger the error of the time information is, for example, the frequency difference of a common single-chip microcomputer crystal oscillator is + -30ppm, and the error of 24 hours is within 3 seconds. However, this error does not affect the time-dependent booting task at boot-up, for example, for a schedule reminder, which is usually a reminder in units of days, the error is negligible for the time-dependent booting task.
In the running process of the television equipment, in order to provide more accurate time for users, the equipment mainboard updates the system clock according to the time information acquired from the network after the network connection is successful.
In this application embodiment, after the power failure of television equipment, equipment mainboard and power management mainboard all cut off the power failure stop work. For example, before the television equipment is started for the first time, the equipment main board and the power management main board are not connected with a power supply and are in a power-off state, and the time is not set for the equipment main board and the power management main board; if the power line of the television equipment is pulled out from the power socket, the equipment main board and the power management main board are powered off, and the power management main board does not manage time information. After the television equipment is started by plugging a power supply, if the equipment main board continues to read the time information from the power supply management main board, the time information may not be read or the wrong time information may not be read. In order to avoid the problems, after the power-off television equipment is started, the power management mainboard sends a specified value to the equipment mainboard; and the equipment mainboard stops executing the operation of setting the system clock according to the updated time information according to the specified value.
The television equipment is started for the first time, or after the television equipment with the power supply disconnected is plugged with the power supply again, the television equipment receives a starting instruction and can start the equipment mainboard. The method comprises the steps that a time obtaining message is sent to a power management mainboard through a communication process after the equipment mainboard is started, at the moment, the power management mainboard can detect that the time information of the power management mainboard has problems or does not record the time information, and can send a specified value to the equipment mainboard, wherein the specified value is a preset mark for notifying that the time information of the power management mainboard has problems, so that the equipment mainboard confirms that the time information on the power management mainboard is incorrect after receiving the specified value, and stops the operation of setting the system equipment.
The specified value can be generated according to a time identification position on the power management mainboard, the time identification position is invalid by default, and after the equipment mainboard transmits the time information to the power management mainboard according to the shutdown instruction, the power management mainboard normally receives the time information at the moment and can set the time identification position to be valid. And the equipment mainboard is powered on and started again according to the starting instruction, and the power management mainboard can reset the time identification position to be invalid after the time information is read from the power management mainboard. When the television equipment is restarted after power failure, the time identification position is also defaulted to be invalid because the power management mainboard does not receive the time information. Therefore, when the equipment mainboard reads time information from the power management mainboard, if the power management mainboard detects that the time identification bit is invalid, the specified value can be sent to the equipment mainboard to inform the equipment mainboard that the time information has problems, and the equipment mainboard cannot set a system clock according to the power management mainboard.
An example is shown in fig. 2, which is a schematic structural diagram of a television apparatus in an embodiment of the present application. The television device comprises a device motherboard 210, a power management motherboard 220 and a bus 230, wherein the device motherboard 210 comprises a central processing unit 212 and other functional modules 214, such as a GPU, a Tuner, and the like; the power management motherboard 220 includes a microcontroller 222 and an infrared receiver 224.

The television apparatus is in a standby state in the power-off mode, at this time, the apparatus main board 210 is in a power-off state, and the central processing unit 212 cannot execute the operation.
The power management motherboard 220 can operate in a standby state of the television apparatus, and the infrared receiver 224 receives an infrared signal of a remote controller key, and if a power-on signal of the remote controller power key is received, a corresponding start instruction can be generated to notify the apparatus motherboard to start and give control right of the infrared receiver. The microcontroller 222 of the power management motherboard 220 may be implemented by a low-power single chip microcomputer, and the current required by the infrared receiver itself is very low, so that the power consumed by the normal operation of the infrared receiver is very low, and the television device can meet the standby power requirement of the household appliance when the power management motherboard is operated in a standby state.
Bus 230 may connect device motherboard 210 and power management motherboard 220 to enable bi-directional communication between device motherboard 210 and power management motherboard 220.
After the device motherboard 210 receives the shutdown instruction, the shutdown operation may be performed, where time information may be obtained from the system clock, the time information is then synchronized to the power management motherboard 220, the infrared receiver 224 of the power management motherboard 220 obtains the control right of the infrared signal, and the device motherboard 210 may be powered off. Thereafter, the ir receiver 224 of the power management motherboard 220 detects the ir signal, and if the timing wake-up is set, detects whether the wake-up time is reached, and the power management motherboard 220 periodically updates the time information to keep in synchronization with the standard universal time.
After that, if the power management motherboard 220 receives a signal of a power key of the remote controller, a start instruction may be generated, or if the detection time reaches the wake-up time, a start instruction may be generated, and the start instruction is sent to the device motherboard 210.
The device motherboard 210 is connected to a power supply, and then performs a boot operation according to the boot instruction, wherein after the kernel is started, a communication process is established to read time information from the power management motherboard 220, and then the system clock is updated. In the subsequent operation process, the network can also be connected to obtain time information from the network so as to update the system clock and improve the accuracy of the system clock.
Referring to fig. 3, a flowchart illustrating steps of an embodiment of a time setting method of the present application is shown, which may include the following steps:
The equipment mainboard of the television equipment can monitor infrared signals to control the television equipment when the television equipment works, if signals of a power key on the infrared remote controller are received, a shutdown instruction can be correspondingly generated, the equipment mainboard can acquire time information of a system clock before closing the equipment mainboard according to the shutdown instruction, then the time information is sent to the power management mainboard, and the control right of the infrared signals can be handed over to the power management mainboard.
The power management mainboard updates the time information and monitors the infrared signals. The power management mainboard can periodically update the time information through the timing device.
Step 306, according to the start instruction, the device motherboard obtains updated time information from the power management motherboard, and sets a system clock according to the updated time information.
The power management mainboard can generate a starting instruction according to the set conditions, the starting instruction is sent to the equipment mainboard, and the equipment mainboard is electrified again and obtains the control right of the infrared signal. After the equipment mainboard is powered on again, the starting operation can be executed, when the kernel of the equipment mainboard is started and the user space program can be started to be executed, the time information can be obtained from the power management mainboard, and then the time of the system clock can be updated according to the time information.
In summary, the device motherboard can send the time information to the power management motherboard according to the shutdown instruction, so that the time information can be updated by the power management motherboard after the device motherboard is powered off, and the time can still be updated normally when the television device is in the standby state, so that the device motherboard obtains the updated time information from the power management motherboard according to the startup instruction, and sets the system clock according to the updated time information, so that the time can be normally obtained when the television device is restarted from the standby state.
Referring to fig. 4, a flow chart of steps of another embodiment of the time setting method of the present application is shown, which may include the following steps:
When the television equipment works, the equipment mainboard of the television equipment can monitor infrared signals to control the television equipment, if signals of a power key on the infrared remote controller are received, a shutdown instruction can be correspondingly generated, or the shutdown instruction is generated according to signals set by timing awakening, and the shutdown instruction carries timing awakening time.
Before the equipment mainboard is closed according to the shutdown instruction, the equipment mainboard acquires the time information of the system clock, then sends the time information to the power management mainboard, and can transfer the control right of the infrared signal to the power management mainboard.
The equipment mainboard can cut off the power supply after sending the time information to the power management mainboard, makes television equipment enter standby state, and correspondingly, after the power management mainboard received the time information, can be effective with the time identification position, and the time information of the management of this moment of representation power management mainboard is accurate. If the time mark is invalid, representing that the time information in the power management mainboard is wrong.
The power management mainboard updates the time information and monitors the infrared signals. The power management motherboard can update the time information periodically through the timing device, for example, the counter updates the time information once, such as 1 second and 1 minute, when the update period is reached, and the power management motherboard determines that the update period is reached according to the crystal oscillator and updates the time information, wherein the update period can be set according to requirements. The crystal oscillator may be called a crystal oscillator, and may be timed by an oscillation frequency, a pulse signal, and the like, and determine the update period. Therefore, the timing device on the power management mainboard can update the time information and keep the accuracy of the time information.
In step 410, the power management motherboard determines whether the set conditions are satisfied.
The setting conditions include: and receiving a starting signal sent by a power key of the remote controller to achieve the awakening time.
If yes, go to step 412; if not, the procedure returns to step 410 to continue the detection.
After receiving the starting signal, the power management mainboard confirms that the set condition is met and can generate a starting instruction; and the power management mainboard determines that the set condition is met after judging that the awakening time is reached, and can generate a starting instruction. And after the starting instruction is generated, the power management mainboard sends the starting instruction to the equipment mainboard.
And the equipment mainboard is electrified again according to the starting instruction and acquires the control right of the infrared signal, and then the equipment mainboard monitors the infrared signal of the remote controller. And the equipment mainboard executes a starting operation, and sends a time acquisition message to the power management mainboard after the kernel of the equipment mainboard is started.
After the kernel of the equipment mainboard is started, the operable communication program adopts the communication program to communicate with the power management mainboard, and the time acquisition message can be sent to the power management mainboard, so that the time information can be read from the power management mainboard.
In step 416, the power management motherboard detects whether the time flag is valid.
Before feeding back time information to the television equipment, the power management main board needs to judge whether the time information stored by the power management main board is accurate or not, wherein whether the storage time is accurate or not is judged according to the time identification bit, and therefore the power management main board detects whether the time identification bit is effective or not.
If yes, i.e. the time flag is valid, the stored time information is represented to be correct, and step 420 may be executed; if not, i.e., the time flag is invalid, indicating that the store is incorrect, step 418 may be performed.
Step 418 returns the instruction value to the device motherboard.
After the time identification bit is judged to be invalid, the power management mainboard acquires a specified value and then can send the specified value to the equipment mainboard.
And step 420, returning the time information to the equipment mainboard.
After the time identification bit is judged to be valid, the power management mainboard can read the stored time information and then send the time information to the equipment mainboard. Therefore, the equipment mainboard reads the time information from the power management mainboard through the communication process.
Step 422, setting the system clock to the time corresponding to the time information.
After the time information is obtained, the system clock can be set to the time corresponding to the time information, so that the time information is updated in the starting process of the equipment mainboard, the time can be updated before networking, and the time-related tasks can be conveniently executed during starting.
For example, the schedule reminder event can be read subsequently according to the system clock. In another example, an offline power-on advertisement may be determined to satisfy the failed advertisement based on system time, and then the offline advertisement may be displayed in the television apparatus to satisfy the timeliness requirements of the advertisement.
After the television equipment is started, if the network connection is successful, time information can be obtained from the network, whether the system clock is accurate or not is judged by adopting the time information, if the system clock is accurate, the system clock does not need to be updated, and if certain errors exist, such as 1 second or 2 seconds or more, the system clock can be updated according to the time information obtained from the network. Therefore, the system clock is corrected to ensure that the equipment mainboard can obtain correct time.
