The main controller enters the normal frequency working mode. In particular, in a joint system composed of multiple different types of controllers, once a control system is awakened, other control systems are also awakened. Once the controller is awakened, all peripheral devices will be awakened and enter the working state. It does not distinguish whether it needs to be awakened or enter the working state. Even if a certain peripheral device does not work, it will also be awakened and in the working state. Although the power consumption of each awakening is small, if the number of awakenings is large enough, it will affect the standby capability of the electronic device.

[0004] Therefore, how to reduce the working power consumption and standby power consumption of electronic devices has not been effectively solved. SUMMARY

[0017] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application are further described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0018] Embodiment one:

[0019] In order to solve the problem that in the related art, when a certain master controller of a terminal device is woken up, other master controllers are also woken up, and all peripheral devices are also woken up, thereby affecting the standby capability of the whole device, the embodiment provides a terminal device hierarchical management system, which comprises: at least one control system, and at least one peripheral device connected to the control system; the control system is configured to wake up the control system corresponding to a wake-up signal when the wake-up signal is received, and to perform hierarchical management on the working mode of the control system according to data load; and the peripheral device is configured to perform data processing according to the wake-up signal.

[0020] In an example of the embodiment, the terminal device is composed of one control system and a plurality of peripheral devices, the control system is configured to realize the control function of the terminal device and the communication function with the peripheral devices, and in the example, one control system and four connected peripheral devices are taken as an example, and the terminal device is taken as an example, as shown in Figure 1 The terminal device comprises one control system 10 and four peripheral devices connected to the control system 10, the four peripheral devices are peripheral device A, peripheral device B, peripheral device C and peripheral device D, and in specific applications, the peripheral devices are peripheral sensors of different bus types with different functions, for example, acceleration sensors with I2C or SPI interfaces, HSIC bus type network card devices, standard serial port devices, radio frequency transmitting and receiving devices, GPIO nodes of the control system, or screen display devices based on I2C or SPI interfaces, and the terminal device in the example can be a communication terminal device, a vehicle-mounted communication device, or a terminal device that can send data via a wireless channel and work independently, which is not limited in the example. The communication terminal device in the embodiment supports USB, serial port, LED lamp, acceleration sensor and other peripheral devices, and the communication device itself has a radio frequency device of a data communication module to realize the communication function with an external network base station, and all peripheral devices can support independent sleep and wake-up. When the terminal device system needs to enter a sleep state, all peripheral buses and devices enter the sleep state in sequence, and finally the device enters the sleep state.

[0021] The peripheral device of the above access control system is configured to allow independent power supply, sleep and wake-up functions, i.e. the control system can independently enable the peripheral device A and can process data of the peripheral device A, can sense an interrupt generated by the peripheral device A and process an interrupt event of the peripheral device A, the control system can independently control power-on enable of the peripheral device A and sleep and wake-up events, and the control system can also independently control power-on enable and sleep and wake-up events of the peripheral device B, the peripheral device C and the peripheral device D. The sleep and wake-up of the peripheral device A, the peripheral device B, the peripheral device C and the peripheral device D are independent of each other, i.e. when the terminal device is woken up from sleep, the control system is woken up and then wakes up one or more peripheral devices which need to perform data processing according to the wake-up event and the data processing process, instead of directly waking up all the peripheral devices to enter a working state after the control system is woken up. For example, after the terminal device is woken up, the control system is in a wake-up state, the control system needs to wake up the peripheral device A to perform data processing according to the wake-up event, and in the process of data processing of the peripheral device A, it is found that the peripheral device B also needs to perform data processing, so the control system then wakes up the peripheral device B to enter a working state to perform data processing.

[0022] The control system 10 grades the working mode of the control system according to the wake-up reason and the data load. In this embodiment, when the terminal device is interrupted or woken up from sleep, the control system is first woken up. The control system after being woken up does not directly enter the normal working state. If the current wake-up is a non-normal demand wake-up, that is, the data load of the terminal device is less than a first preset threshold, data processing is not required, and the peripheral device does not need to perform data processing, the working mode of the control system enters an ultra-low frequency mode. In the ultra-low frequency mode, the control system is in a wake-up state, and each peripheral device is in a sleep state. In the ultra-low frequency mode, the frequency of the CPU processor of the control system is very low, within 5% of the full load state. In the ultra-low frequency mode, the control system completes some low-power consumption applications of recording some states in the memory. When the control system is woken up, the task needs to be processed. When the data load is greater than the first preset threshold, the control system enters a medium frequency mode. In the medium frequency mode, the control system is in a wake-up state, and at least one of the peripheral devices is in a wake-up state, and at least one is in a sleep state. When the wake-up reason is that an event needs to be processed by a peripheral device, the control system enters the medium frequency mode and wakes up the peripheral device that needs data processing to enter the working state, and the peripheral device that does not need data processing continues to sleep. When the data load is greater than a second preset threshold, the control system enters a full-speed mode. In the full-speed mode, the control system is in a wake-up state, and each peripheral device is in a wake-up state. In an example, when the data load reaches 90% of the current total amount, the control system enters the full-speed mode, and all peripheral devices are woken up for data processing. The control system 10 in this embodiment includes a control module and a monitoring module. The monitoring module is used to monitor the wake-up signal and the data load of the system. The control module controls the control system 10 to enter the corresponding working mode and wakes up the peripheral device that needs data processing. When the wake-up reason is a non-normal demand wake-up, the control system 10 enters the ultra-low frequency mode. After a preset time, the control module generates a sleep instruction to control the control system 10 to enter the sleep state again.

[0023] The terminal device hierarchical management system provided in this embodiment includes a control system and at least one peripheral device connected to the control system. When the control system receives a wake-up signal, the control system corresponding to the wake-up signal is woken up, and the working mode of the control system is graded according to the data load. Through hierarchical management of the terminal device, when the terminal device is woken up from sleep, the working mode of the control system of the terminal device is graded, and the peripheral device that needs data processing is woken up to enter the working state, instead of waking up all peripheral devices, thereby reducing the power consumption of the device and prolonging the standby time.

[0024] Embodiment Two:

[0025] In order to solve the problem that in the related art, when a certain master of a terminal device is woken up, other masters are also woken up, and all peripheral devices are also woken up, thereby affecting the standby capability of the whole device, the embodiment provides a terminal device hierarchical management system, comprising: at least one control system, and at least one peripheral device connected with the control system; the control system is used for waking up the control system corresponding to a wake-up signal when the wake-up signal is received, and classifying the working mode of the control system according to data load; and the peripheral device is used for performing data processing according to the wake-up signal.

[0026] In the embodiment, the terminal device is composed of two control systems and a plurality of peripheral devices, the control system is used for realizing the control function of the terminal device and the communication function with the peripheral devices, in the embodiment, two control systems and four connected peripheral devices are taken as an example, see Figure 2The terminal device includes two control systems, control system 20 and control system 21, and a plurality of peripheral devices connected to control system 20 are peripheral device A1, peripheral device B1, peripheral device C1 and peripheral device D1, and a plurality of peripheral devices connected to control system 21 are peripheral device A2, peripheral device B2, peripheral device C2 and peripheral device D2. In specific applications, these peripheral devices are different bus type peripheral sensors with different functions, such as I2C or SPI interface acceleration sensors, HSIC bus type network card devices, standard serial port devices, RF transceiver devices, GPIO nodes of control system peripherals, or I2C or SPI interface screen display devices. The peripheral devices connected to the control system are configured to allow independent power supply, sleep and wake-up functions, that is, control system 20 can independently enable peripheral device A1 and process data of peripheral device A1, can sense interrupts generated by peripheral device A1 and process interrupt events of peripheral device A1, and can independently control power-on enable, sleep and wake-up events of peripheral device A1. Control system 20 can also independently control power-on enable, sleep and wake-up events of peripheral device B1, peripheral device C1 and peripheral device D1. The sleep and wake-up of peripheral device A1, peripheral device B1, peripheral device C1 and peripheral device D1 are independent of each other, that is, when the terminal device is woken up from sleep, the control system is woken up according to the wake-up event and data processing process to wake up one or more peripheral devices that need to be woken up for data processing, instead of directly waking up all peripheral devices to enter the working state after the control system is woken up. For example, when the terminal device is woken up, control system 20 is in a wake-up state, control system 20 needs to wake up peripheral device A1 for data processing according to the wake-up event, and finds that peripheral device B1 is also needed for data processing during the data processing of peripheral device A1, so control system then wakes up peripheral device B1 to enter the working state for data processing.

[0027] In this embodiment, control system 20 and control system 21 have independent sleep and wake-up functions, and each peripheral device connected thereto also has geographical sleep and wake-up functions, that is, when the terminal device needs to wake up only control 20, control system 21 and the peripheral devices connected thereto are still in sleep, and will not be woken up from sleep at the same time as control system 20 is woken up. When control system 20 is woken up for data processing, control system 21 is needed for data processing, control system 20 can wake up control system 21 to perform related data processing.

[0028] The terminal device in the embodiment can be a communication terminal device, a vehicle-mounted communication device, and can also be a stand-alone terminal device capable of transmitting data via a wireless channel. In an example of the embodiment, the terminal device is a vehicle-mounted terminal device composed of a single-chip system and a communication terminal, that is, the control system 21 is a single-chip microcomputer, the single-chip system is a lower computer system, the peripheral devices connected thereto are a CAN bus and other sensor devices, and the communication terminal is an upper computer system, that is, the control system 20 is a communication terminal, which implements the networking function of the terminal device and completes the communication function of uploading and downloading vehicle-mounted networking data. The upper computer and the lower computer can be connected through a serial port, SPI, I2C, and the like. In the embodiment, the lower computer and the upper computer are connected through a serial port to realize data communication between the upper computer and the lower computer. Meanwhile, the upper computer and the lower computer are configured with multiple state display interfaces to display the current working state of each other, such as working, hibernation, and the like. When the upper computer and the lower computer system are in a hibernation state, the CAN network of the lower computer accesses the CAN bus system of the vehicle. Due to the signals sent by other vehicle CAN system devices, the CAN of the lower computer is awakened. The CAN bus task of the lower computer belongs to a high-level task, and the working mode of the lower computer is switched from the ultra-low frequency mode to the full-speed mode to enter the full-speed running state. However, the upper computer cannot be directly awakened, and the bus connected to the upper computer is in a hibernation state. The lower computer further analyzes the data received and transmitted after the CAN bus is awakened. After the analysis, it is judged whether the network packet is a broadcast signal or other vehicle parameter signal, and whether it needs to be reported to a higher network. If it is a broadcast network data packet or a lower computer parameter data packet, the lower computer will automatically enter the hibernation state again after the analysis and processing are completed. If the data sent by the CAN network needs to be communicated with the external network service, the associated bus of the upper computer and the lower computer is awakened, so as to awaken the upper computer. Since the communication bus is awakened, the upper computer is in an awakened state and enters the ultra-low frequency mode. It is judged that the communication bus is awakened and there is a network data packet to be sent. The CAN network total vehicle interaction data belongs to a high-level task. The upper computer is immediately switched from the ultra-low frequency mode to the full-speed mode. Finally, the vehicle-mounted terminal device enters the full-speed mode, awakens the radio frequency main module, and is in the full-speed working mode.

[0029] The terminal device hierarchical management system provided in the embodiment includes a control system and at least one peripheral device connected to the control system. When the control system receives a wake-up signal, the control system corresponding to the wake-up signal is awakened, and the working mode of the control system is classified according to the data load. Through hierarchical management of the terminal device, when the terminal device is awakened from hibernation, the working mode of the control system of the terminal device is classified, and the peripheral device that needs to be processed is awakened to enter the working state, instead of awakening all peripheral devices, so as to reduce the power consumption of the device and prolong the standby time.

[0030] Embodiment three

[0031] In order to solve the problem that in the related art, when a certain master controller of a terminal device is woken up, other master controllers are also woken up, and all peripheral devices are also woken up, thereby affecting the standby capability of the whole device, the embodiment provides a terminal device hierarchical management method, which comprises the following steps. Figure 3 The method comprises the following steps.

[0032] S301: When a terminal device receives a wake-up signal in a sleep state, a control system corresponding to the wake-up signal is woken up, and the working mode of the control system in the wake-up state is classified according to data load.

[0033] The terminal device comprises at least one control system and at least one peripheral device connected to the control system, and each control system has independent sleep and wake-up functions, that is, when the terminal device is woken up in a sleep state, the corresponding control system is woken up according to a wake-up signal, instead of directly waking up all control systems.

[0034] S302: The peripheral device that needs to process data is woken up according to the working mode.

[0035] Each peripheral device has independent sleep and wake-up functions, that is, when a control system is woken up, the control system wakes up the peripheral device that needs to process data according to the current working mode, instead of directly waking up all peripheral devices connected to the control system from the sleep state to the working state, and the peripheral device that does not need to process data continues to sleep.

[0036] In step S301, the working mode of the control system is classified according to the wake-up reason and data load, which comprises the following steps.

[0037] When the wake-up reason is an abnormal demand wake-up, the working mode of the control system is a super-low frequency mode, the control system is in a wake-up state, and each peripheral device is in a sleep state; when the data load is less than a preset threshold, the working mode of the control system is a medium frequency mode, the control system is in a wake-up state, and the at least one peripheral device is in a wake-up state; when the data load is greater than the preset threshold, the working mode of the control system is a full-speed mode, the control system is in a wake-up state, and each peripheral device is in a wake-up state.

[0038] In the embodiment, when the wake-up reason is abnormal demand wake-up, the control system enters the ultra-low frequency mode, and after a preset time, the control system enters the sleep state again according to the instruction. In the medium frequency mode, the control system wakes up the peripheral device in the sleep state associated with the peripheral device in the wake-up state according to the data processing process, that is, the control system currently wakes up one of the peripheral devices connected to the control system for data processing. When another peripheral device is needed to process data in the data process, the control system can wake up the peripheral device needed to process data.

[0039] In the embodiment, the working mode of the control system is classified according to the wake-up signal and the data load. Referring to FIG. 1, the working mode of the control system is classified into L0: ultra-low frequency mode, L1: medium frequency mode, and L2: full-speed mode. Figure 4 The terminal device sleep and wake-up control method flowchart provided in the embodiment classifies the working mode of the control system into L0: ultra-low frequency mode, L1: medium frequency mode, and L2: full-speed mode. In the ultra-low frequency mode, the control system is in the wake-up state, and each peripheral device is in the sleep state. In the ultra-low frequency mode, the frequency of the CPU processor of the control system is very low, and is within 5% of the full load state. The terminal device receives a wake-up signal in the sleep state, judges that the current wake-up reason is abnormal demand wake-up, or only records some states in the memory, and the like low-power-consumption application can be completed in the L0 ultra-low frequency mode. After the completion, the terminal device enters the sleep state again. If the data processing of a peripheral device is needed at this time, since the data processing cannot be performed in the ultra-low frequency mode, the performance requirement of the data processing cannot be met. At this time, the control system is switched to the L1 medium frequency mode, and the peripheral device needed to process data is woken up. In the medium frequency mode, the current system task is in the moderate scheduling state, and only the necessary peripheral device is woken up according to the data processing process, and the other peripheral devices continue to sleep. When the data load reaches 90% of the total load, the control system is switched to the L2 full-speed mode, and all the peripheral devices are in the wake-up state for data processing according to the need.

[0040] In an application scenario, the communication terminal device is in the sleep state, an external radio frequency interrupt signal is generated due to network signal change, the control system is woken up, and the terminal system enters the L0 mode. In the L0 mode, the current network change reason is further judged. At this time, other peripheral devices do not need to be woken up, and the L1 does not need to be upgraded for processing. After the judgment is completed, the wireless terminal device enters the sleep state again, which can greatly reduce the power consumption of the device.

[0041] The terminal device hierarchical management method provided in the embodiment comprises: when a terminal device receives a wake-up signal in a sleep state, waking up a control system corresponding to the wake-up signal; the control system in the wake-up state classifying the working mode of the control system according to a wake-up reason and data load; and waking up the peripheral device that needs to process data according to the working mode. Through hierarchical management of the working mode of the terminal device, when the terminal device wakes up from the sleep state, the working mode of the control system of the terminal device is classified, only the peripheral device that needs to process data is woken up to enter the working state, instead of waking up all peripheral devices, thereby reducing the power consumption of the device and prolonging the standby time.

[0042] It will be apparent to those skilled in the art that all or some of the steps, functions, modules and units in the methods described above can be implemented by software (which can be realized by computer program codes executable by a computing device), firmware, hardware, or any combination thereof. In a hardware implementation, the split between the functional modules / units referred to in the above description does not necessarily correspond to the split between physical components; for example, one physical component can serve multiple functions, or one function or step can be performed by several physical components working together. Some or all of the physical components can be implemented as software executed by a processor, such as a central processing unit, a digital signal processor, or a microprocessor, or as hardware, or as an integrated circuit, such as an application-specific integrated circuit.

[0043] In addition, it is well known to those skilled in the art that communication media typically includes computer readable instructions, data structures, computer program modules or other data in modulated data signals such as carrier waves or other transport mechanisms, and can include any information delivery media.
