[0052] In order to make the above objectives, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0053] With reference to Figure 1 , a flow chart of steps of a terminal device upgrading method provided in an embodiment of the present application is shown, the terminal device comprising at least two control channels, the control channels comprising at least a first control channel and a second control channel, wherein the second control channel is used to execute a user instruction received by the terminal device during firmware upgrading, and the method can specifically comprise the following steps:

[0054] Step 101, triggering the terminal device to trigger upgrading, and recording key state variables of the terminal device through the first control channel.

[0055] In an embodiment of the present application, the terminal device can be a smart home device or other device, and exemplarily, the terminal device can comprise at least an air conditioner device, a smart lamp, a smart socket, a lighting device, a dehumidifier, a switch, a socket, a sensor device, a smoke alarm, a smart door lock, a security camera and the like. The terminal device can comprise at least two control channels, and the control channels can comprise at least a first control channel and a second control channel. The first control channel and the second control channel are two independent control channels, and the first control channel and the second control channel are connected through SPI (Serial Peripheral Interface). The firmware of the second control channel is simpler than that of the first control channel. The first control channel can be a main control channel, and the second control channel can be an auxiliary control channel. The second control channel is used to execute a user instruction received by the terminal device during firmware upgrading, such as a user instruction about turning on, turning off, timing and the like. In order to facilitate the description, the smart home device is mainly taken as an example for description, and of course, the terminal device of the present embodiment is not limited to the smart home device.

[0056] With reference to Figure 2Fig. 1 is a schematic diagram of a dual-channel parallel control system architecture provided in an embodiment of the present application, the system architecture comprising a server (cloud server) and a terminal device, wherein the terminal device can be composed of a main control channel, an auxiliary control channel, a communication module, an instruction queue module and a state synchronization module. Specifically, the main control channel is responsible for normal operation of smart home devices, firmware download and installation, etc., and runs complete function logic; the auxiliary control channel is a special module for smart home devices, and runs a minimalist firmware, and only handles user instructions during firmware upgrade of the smart home devices. The main control channel and the auxiliary control channel are connected through a high-speed SPI interface, so that when the control right of the terminal device is switched between the two channels, the switching delay is low. The communication module supports bidirectional communication between the smart home device and the cloud server and a mobile phone APP (Application, application program); the instruction queue module adopts a double-buffering design to separately manage real-time user instructions and delayed user instructions; and the state synchronization module ensures the state consistency between the main control channel and the auxiliary control channel. Among them, the cloud server is responsible for firmware distribution, and can use block checking to reduce bandwidth requirements, i.e., firmware upgrade data used for firmware upgrade of the terminal device can be divided into multiple firmware upgrade data blocks, and then the firmware upgrade data blocks are sent to the terminal device, so that the terminal device can perform firmware upgrade based on the firmware upgrade data blocks.

[0057] Among them, the main control channel adopts an MCU (Microcontroller Unit, microcontroller unit), such as a 32-bit ARM Cortex-M4, the auxiliary control channel adopts a low-power MCU, such as an 8-bit AVR, and the main control channel and the auxiliary control channel can communicate through a 1 Mbps (Megabit per second, megabit per second) SPI interface, with logic isolation and power sharing. The auxiliary control channel can independently run and report to the cloud server in case of exception. The embodiment of the present application only needs a small amount of hardware modification, has low cost, and is suitable for various smart home devices.

[0058] In the embodiment of the present application, when the smart home device triggers the firmware upgrade, the cloud server pushes a new firmware notification, and after the smart home device confirms the new firmware notification, the smart home device enters an upgrade mode to perform the firmware upgrade. Before the firmware upgrade is performed, the smart home device has control over a first control channel. At this time, the current key state variables of the smart home device can be recorded through the first control channel. The key state variables refer to key operating parameters of the smart home device at a certain time. The key state variables of the smart home device can include key state variables (such as switch states), timing tasks (such as countdown remaining time), network configurations (such as WiFi connection keys), and the like. For example, assuming that the temperature of the air conditioner device is set to 23 degrees before the firmware upgrade is performed, the temperature of 23 degrees can be recorded as the current key state variable of the air conditioner device.

[0059] Step 102, in the process of controlling the firmware upgrade of the terminal device through the first control channel, switching to control the terminal device through the second control channel.

[0060] Step 103, when receiving a user instruction, processing the user instruction through the second control channel.

[0061] In the embodiment of the present application, the smart home device can be controlled to perform the firmware upgrade through the first control channel. In the process of controlling the smart home device to perform the firmware upgrade through the first control channel, the first control channel can focus on the firmware upgrade and does not respond to other operations at this time. For example, if the smart home device receives a user instruction, the first control channel does not process the user instruction.

[0062] In addition, the smart home device can be switched to be controlled through the second control channel, so that the user instruction can be received through the second control channel and processed accordingly according to the user instruction. The processing of the user instruction can include but is not limited to real-time processing, buffering, and / or discarding.

[0063] Step 104, when the firmware upgrade of the terminal device through the first control channel is completed, switching to control the terminal device through the first control channel, and restoring the terminal device after the firmware upgrade to the key state variables.

[0064] In the embodiment of the present application, when the firmware upgrade of the smart home device through the first control channel is completed, the smart home device can be switched to continue to be controlled through the first control channel. At this time, the smart home device after the firmware upgrade can be restored to the key state variables. For example, the temperature of the air conditioner device is originally 23 degrees. If the key state variables do not change during the firmware upgrade, the temperature of the air conditioner device can continue to be maintained at 23 degrees.

[0065] In the related technical solutions, some high-end devices use dual-core processors to realize separated firmware upgrade and user instruction processing, but the cost is high and the low-cost demand of smart home devices is not met. The embodiment of the present application separates firmware upgrade and user instruction processing through a main control channel and an auxiliary control channel, realizes parallel running of the two, only needs a small amount of hardware modification, has low cost, and is suitable for various smart home devices.

[0066] In the embodiment of the present application, the terminal device includes at least two control channels, including at least a first control channel and a second control channel, wherein the second control channel is used to execute user instructions received by the terminal device during firmware upgrade, the key state variables of the terminal device can be recorded through the first control channel when the terminal device is triggered to upgrade, the terminal device can be controlled through the second control channel during firmware upgrade of the terminal device controlled through the first control channel, if the user instructions are received, the user instructions can be processed through the second control channel, finally, when the firmware upgrade of the terminal device controlled through the first control channel is completed, the terminal device can be controlled through the first control channel again, and the terminal device after firmware upgrade is restored to the key state variables. In the process of firmware upgrade of the terminal device, the terminal device is controlled through the first control channel for firmware upgrade, and the user instructions are received and processed through the second control channel, so that the user instructions can be processed in real time during firmware upgrade of the terminal device, the control of the terminal device is not interrupted, and the user experience is ensured. At the same time, the key state variables can be recorded before firmware upgrade of the terminal device, and synchronization can be realized through the recorded key state variables after firmware upgrade of the terminal device, so that the consistency of the key state variables of the terminal device is ensured.

[0067] In one embodiment of the present application, the step 103 of processing the user instructions through the second control channel can include:

[0068] When the user instructions are first preset priority instructions, the user instructions are buffered into a real-time queue, and the user instructions in the real-time queue are executed through the second control channel;

[0069] When the user instructions are second preset priority instructions, the user instructions are discarded through the second control channel;

[0070] When the user instructions are not first preset priority instructions and not second preset priority instructions, the user instructions are buffered into a buffer queue through the second control channel; the user instructions in the buffer queue are executed through the first control channel when firmware upgrade of the terminal device is completed.

[0071] In the embodiment of the present application, the dynamic priority allocation adopts a preemptive scheduling algorithm, and the user instructions are divided into three priority levels of instructions: real-time instructions (such as emergency power-off) are directly responded by the auxiliary control channel; buffer instructions (such as mode switching) are stored in a ring buffer of instructions, and are executed by the main control channel after the smart home device firmware upgrade is completed; and discarded instructions (such as non-critical state query) avoid invalid requests from occupying system resources. Of course, the above-mentioned division of user instructions is only an example, and in actual application, the priority levels of user instructions can be divided into other priority levels according to needs, and the processing mode corresponding to the user instructions of the priority level, and the embodiment of the present application does not need to be limited thereto.

[0072] Exemplarily, the first preset priority instruction can be a real-time instruction, and the second preset priority instruction can be a discarded instruction. When the user instruction is the first preset priority instruction, that is, the user instruction is a real-time instruction, the user instruction can be buffered to the real-time queue, and the user instruction in the real-time queue is executed through the second control channel; when the user instruction is the second preset priority instruction, that is, the user instruction is a discarded instruction, the user instruction can be discarded through the second control channel; when the user instruction is not the first preset priority instruction and not the second preset priority instruction, it is indicated that the user instruction is not a real-time instruction or a discarded instruction, and at this time, the user instruction can be buffered to the buffer queue through the second control channel, wherein the user instruction in the buffer queue is executed through the first control channel when the firmware upgrade of the smart home device is completed and the first control channel takes control. It should be noted that if the user instruction in the real-time queue is executed through the second control channel, if the user instruction affects the critical state variable of the smart home device, for example, the user instruction is to increase the temperature of the air conditioning device from 23 degrees to 24 degrees, the critical state variable of the air conditioning device will be updated to 24 degrees.

[0073] The embodiment of the present application sets a queue management strategy for user instructions, the queue management strategy is designed with a double-buffer queue, which includes a real-time queue and a buffer queue, wherein the real-time queue is used to save user instructions (real-time instructions) that need to be executed immediately, for example, controlling the smart home device to start or close immediate operations, the buffer queue (with a capacity slightly larger than the real-time queue) can store non-real-time instructions, the complexity of these non-real-time instructions can be higher than that of real-time instructions, and the user instructions are sorted according to the emergency priority. Wherein, the system realizes the quick retrieval of user instructions in the real-time queue and the buffer queue through a hash linked list, and executes according to the timestamp order, ensuring the time sequence correctness of user instruction processing. The embodiment of the present application provides an instruction queue redirection mechanism, dynamically allocates real-time instructions to an auxiliary control channel, and stores non-real-time instructions to a buffer queue, and seamlessly executes after upgrading, that is, the smart home device can still respond to user instructions in real time during the firmware upgrade of the embodiment of the present application, eliminating operation interruption, and realizing seamless user experience.

[0074] In an embodiment of the present application, during the process of controlling the firmware upgrade of the terminal device through the first control channel, after switching to control the terminal device through the second control channel, the method can further include:

[0075] receiving a differential state package sent by the first control channel through the second control channel; the differential state package is sent by the first control channel when a preset progress is completed;

[0076] performing cyclic redundancy check on the differential state package;

[0077] when the cyclic redundancy check on the differential state package is successful, synchronizing the upgrade progress and the key state variable of the terminal device of the second control channel and the first control channel according to the differential state package through the second control channel.

[0078] In the embodiment of the present application, the smart home device sets a differential synchronization mechanism, specifically, the main control channel sends a differential state package to the auxiliary control channel every time it completes a preset progress, for example, every time it completes 1% of the firmware writing progress. It should be noted that these differential state packages only contain the state change amount of the key state variable rather than the complete key state variable, so as to reduce the bandwidth and reduce the overall power consumption. Each differential state package can use a CRC (Cyclic Redundancy Check) check mechanism to ensure data integrity, wherein the CRC-8 check mechanism in the CRC check mechanism can be used for the check of the differential state package. When the cyclic redundancy check of the differential state package is successful, the second control channel can synchronize the upgrade progress and the key state variable of the terminal device of the first control channel and the second control channel according to the differential state package, so that the upgrade progress and the key state variable of the first control channel and the second control channel remain consistent.

[0079] In an embodiment of the present application, during the process of controlling the firmware upgrade of the terminal device through the first control channel, after switching to control the terminal device through the second control channel, the method can further include:

[0080] sending a heartbeat package to the first control channel through the second control channel; the heartbeat package is sent at a preset time interval; the first control channel is used to resend a differential state package to the second control channel when it is determined that the upgrade progress and / or the key state variable of the terminal device of the second control channel and the first control channel are inconsistent according to the heartbeat package.

[0081] In the embodiment of the present application, the auxiliary control channel can send a heartbeat package to the first control channel at a preset time interval, for example, send a heartbeat package to the first control channel every second. Based on the heartbeat package, it can be determined whether the upgrade progress and / or the key state variable of the smart home device of the second control channel and the first control channel are consistent. If the heartbeat package check is successful, it can be determined that the upgrade progress and the key state variable of the smart home device of the second control channel and the first control channel are consistent, and no further processing is required. If the heartbeat package check fails or data is lost, it is determined that the upgrade progress and / or the key state variable of the smart home device of the second control channel and the first control channel are inconsistent, which triggers the main control channel to perform data retransmission. At this time, the first control channel can resend a differential state package to the second control channel to synchronize the upgrade progress and the key state variable of the second control channel and the first control channel, thereby ensuring the state synchronization reliability of the system during the firmware upgrade process.

[0082] In an embodiment of the present application, when the firmware upgrade of the terminal device controlled through the first control channel is completed, switching to control the terminal device through the first control channel and restoring the terminal device after firmware upgrade to the key state variable can include:

[0083] When the firmware upgrade of the terminal device controlled through the first control channel is completed, receiving a hardware trigger signal through the second control channel;

[0084] The second control channel switches to use the firmware of the terminal device after upgrade according to the hardware trigger signal, and switches to control the terminal device through the first control channel, and restores the terminal device after firmware upgrade to the key state variable.

[0085] In a specific implementation, the key state variable of the smart home device can include a key state variable (such as a switch state), a timing task (such as a countdown remaining time), a network configuration (such as a WiFi connection key), and the like.

[0086] In an embodiment of the present application, atomic operation guarantees the key state variable, and a memory barrier technology can be used to avoid multi-thread access conflicts. After the firmware upgrade of the smart home device is completed, the system will notify the auxiliary control channel to switch to the new firmware after upgrade through a hardware trigger signal, such as a GPIO (General-purpose input / output) interrupt. After switching to control the terminal device through the main control channel, the consistency of the device state and other key state variables before and after upgrade is ensured through snapshot and real-time update and the like. Through a lightweight state synchronization protocol, efficient state synchronization of the main control channel and the auxiliary control channel is realized, and the consistency of the device state and other key state variables before and after firmware upgrade is ensured.

[0087] In an embodiment of the present application, the method can further include:

[0088] Obtaining a network state of the terminal device;

[0089] Adjusting the size of the firmware upgrade data block obtained from the cloud server according to the network state;

[0090] Obtaining the firmware upgrade data block of the size from the cloud server, so as to control the firmware upgrade of the terminal device through the first control channel according to the firmware upgrade data block.

[0091] In the embodiment of the present application, the network state of the smart home device can be acquired in real time, for example, whether there are abnormal conditions such as lag, delay, etc., and then the size of the firmware upgrade data block acquired from the cloud server can be adjusted according to the network state. The smart home device can acquire the firmware upgrade data block of the size from the cloud server to control the firmware upgrade of the terminal device according to the firmware upgrade data block through the first control channel. For example, if it is determined according to the network state of the smart home device that the network state is good at this time, there are no abnormal conditions such as lag, delay, etc., the size of the firmware upgrade data block acquired from the cloud server can be increased, so that the firmware upgrade efficiency can be improved. On the contrary, if it is determined according to the network state of the smart home device that the network has abnormal conditions such as lag, delay, etc. at this time, the size of the firmware upgrade data block acquired from the cloud server can be reduced. In this way, even if the transmitted firmware upgrade data block has a problem, the transmission can be quickly completed again, and since the firmware upgrade data block is small, the cost of retransmission is also small.

[0092] In an embodiment of the present application, the firmware upgrade data block of the size is acquired from the cloud server to control the firmware upgrade of the terminal device according to the firmware upgrade data block through the first control channel, comprising:

[0093] The firmware upgrade data block of the size is acquired from the cloud server;

[0094] The firmware upgrade data block is cyclic redundancy checked;

[0095] When the cyclic redundancy check of the firmware upgrade data block is successful, the firmware upgrade of the terminal device is controlled according to the firmware upgrade data block through the first control channel;

[0096] When the cyclic redundancy check of the firmware upgrade data block fails, the step of acquiring the firmware upgrade data block of the size from the cloud server is returned.

[0097] In the embodiment of the present application, the size of the firmware upgrade data block obtained from the cloud is dynamically adjusted in real time according to the network state, and then the obtained firmware upgrade data block can be subjected to cyclic redundancy check (CRC), wherein the firmware upgrade data block can be subjected to CRC32 check, when the CRC32 check fails, the firmware upgrade data block of the size is automatically obtained from the cloud server again; when the CRC32 check succeeds, the smart home device can be controlled to perform firmware upgrade through the first control channel according to the firmware upgrade data block, until the firmware upgrade of the smart home device is completed. In the embodiment of the present application, the check data (including the differential state package and the firmware upgrade data block) and the user instruction share the channel, so that the existing hardware can be multiplexed without additional communication interface. Of course, if the firmware upgrade of the smart home device fails, the firmware of the smart home device before the upgrade is rolled back. Through real-time verification of the integrity of the firmware upgrade data block during firmware upgrade, the efficiency and stability are taken into account.

[0098] In an embodiment of the present application, the method can further comprise:

[0099] When the number of the firmware-updated terminal devices in the specified area is less than or equal to the number of the non-firmware-updated terminal devices, a target terminal device is determined from the firmware-updated terminal devices, a firmware upgrade data block is obtained from the target terminal device, and firmware upgrade of the terminal device is controlled through the first control channel according to the firmware upgrade data block.

[0100] When the number of the firmware-updated terminal devices in the specified area is greater than the number of the non-firmware-updated terminal devices, a firmware upgrade data block is obtained from the firmware-updated terminal devices, and firmware upgrade of the terminal device is controlled through the first control channel according to the firmware upgrade data block.

[0101] In a specific implementation, the terminal device can be a smart home device, in a designated area, for example, a plurality of smart home devices are usually deployed in a family, and there can also be a plurality of same smart home devices, when the number of smart home devices that have been upgraded in firmware in the designated area is small, for example, less than or equal to the smart home devices that have not been upgraded in firmware, the target device is preferentially selected from the smart home devices that have been upgraded in firmware with low load or good network quality to provide the firmware upgrade data block, reducing the dependence on the cloud server, and at the same time, the transmission efficiency can be improved; on the contrary, if the number of smart home devices that have been upgraded in firmware is large, for example, greater than the smart home devices that have not been upgraded in firmware, then all the smart home devices that have been upgraded in firmware are selected to obtain the firmware upgrade data block, and the localized transmission (such as a Mesh network) between devices is used to accelerate the firmware upgrade process. For example, in a certain family, there are 10 smart home devices, if only 2 of them have completed firmware upgrade, then the smart home device with the strongest signal or closest to the data distribution node is selected to distribute the firmware upgrade data block to the smart home devices that have not been upgraded in firmware; if 7 of the smart home devices have been upgraded in firmware, then all the smart home devices that have been upgraded in firmware can be selected to respectively transmit different firmware upgrade data blocks, thereby reducing the cloud bandwidth pressure and improving the speed of the smart home devices to obtain all the firmware upgrade data blocks.

[0102] It can be seen that, when there are a small number of smart home devices that have been upgraded in firmware in a designated area, the embodiment of the present application selects the optimal (low load, good network) smart home device to distribute the firmware upgrade data block, avoids performance bottlenecks, when there are a large number of smart home devices that have been upgraded in firmware, fully utilizes the distribution capability of all smart home devices, parallel transmission, flexible adaptation to different scenarios, and optimizes resource utilization.

[0103] In the embodiment of the present application, when the smart home device triggers firmware upgrade, the cloud server pushes a new firmware notification, and the smart home device confirms the new firmware notification and enters an upgrade mode to perform firmware upgrade. The state synchronization module first records the current key state variable, and then the main control channel transfers the control right to the auxiliary control channel. During the firmware upgrade process, the main control channel performs firmware download, block verification and installation in parallel, and the auxiliary control channel processes user core instructions / real-time instructions in real time (classified by the instruction queue module: real-time instructions are directly executed, and non-real-time instructions are stored in a buffer queue). After the firmware upgrade is completed, the main control channel verifies the integrity of the newly upgraded firmware and generates the latest device state, and the auxiliary control channel returns the buffer queue instructions and the device state. Finally, the smart home device switches back to the main control channel, executes the buffered instructions in the buffer queue, and restores the complete function.

[0104] The embodiment of the present application solves the problem of the smart home device in the related scheme that cannot respond to the user instruction due to the processor resource occupation during the firmware upgrade, and specifically realizes seamless control through double-channel parallel control and instruction queue redirection. In order to enable those skilled in the art to better understand the embodiment of the present application, the following is described with one example.

[0105] Referring to Figure 3 , the embodiment of the present application provides a flowchart of firmware upgrade of a smart home device, and the specific steps executed by the smart home device can include: detecting firmware update; if the firmware is the latest firmware, continuing normal operation; if the firmware is not the latest firmware, generating a state snapshot according to a key state variable of the smart home device, and transmitting to an auxiliary control channel through an SPI interface; upgrading the main control channel; checking the firmware in blocks; processing real-time instructions by the auxiliary channel; redirecting non-real-time instructions to a buffer queue; returning the buffer instructions; synchronizing the state and the queue by the main control channel; restoring the main control channel; executing the buffer instructions; and ending.
