[0031] The method and device for batch upgrade, host device, device to be upgraded, and computer-readable storage medium provided by the embodiments of the present disclosure can achieve the following technical effects:

[0032] By connecting the main UART serial port receiving pin of the host device and the slave UART serial port sending pins of multiple devices to be upgraded through diodes respectively, the diode limits the sink current between the main UART serial port receiving pin of the host device and the slave UART serial port sending pins of multiple devices to be upgraded, so that the sink current is limited within a range equivalent to an open circuit. If the slave UART serial port sending pin of the device to be upgraded being upgraded is at a low level and the slave UART serial port sending pin of the device to be upgraded not yet upgraded is at a high level, since the current will not flow from the slave UART serial port sending pin of the device to be upgraded not yet upgraded into the slave UART serial port sending pin of the device to be upgraded being upgraded, the problem that the low level of the slave UART serial port sending pin of the device to be upgraded being upgraded rises will not be caused. Since the UART serial port sending pin uses a low level as the flag for sending information, and the main UART serial port receiving pin of the host device is in a pull-up input state and does not affect the high-level sampling, the normal communication between the slave UART serial port sending pin of the device to be upgraded being upgraded and the main UART serial port receiving pin of the host device is guaranteed.

[0049] Combined Figure 1 As shown, the embodiments of the present disclosure provide a device 1 for batch upgrade, which is applied to a host device and includes: a main UART (Universal Asynchronous Receiver / Transmitter) serial port receiving pin 11 and a main UART serial port transmitting pin 12. The main UART serial port receiving pin 11 is used to connect to the slave UART serial port transmitting pin of the i-th device to be upgraded through the i-th diode 13. Wherein, the anode of the i-th diode 13 is connected to the main UART serial port receiving pin 11 of the host device, and the cathode is connected to the slave UART serial port transmitting pin of the i-th device to be upgraded. The main UART serial port transmitting pin 12 is used to connect to the slave UART serial port receiving pin of the i-th device to be upgraded. Wherein, i = 1, 2..., N. N is a natural number.

[0050] Using the device 1 for batch upgrade provided by the embodiments of the present disclosure, by connecting the receiving pin 11 of the main UART serial port of the host device and the transmitting pins of the slave UART serial ports of multiple devices to be upgraded through diodes 13 respectively, the sink current between the receiving pin 11 of the main UART serial port of the host device and the transmitting pins of the slave UART serial ports of multiple devices to be upgraded is restricted by the diodes 13, so that the sink current is restricted within a range equivalent to an open circuit. If the transmitting pin of the slave UART serial port of the device to be upgraded being upgraded is at a low level and the transmitting pin of the slave UART serial port of the device to be upgraded not yet upgraded is at a high level, since the current will not flow from the transmitting pin of the slave UART serial port of the device to be upgraded not yet upgraded into the transmitting pin of the slave UART serial port of the device to be upgraded being upgraded, the problem that the low level of the transmitting pin of the slave UART serial port of the device to be upgraded being upgraded rises will not be caused. Since the UART serial port transmitting pin uses the low level as the flag for transmitting information and the receiving pin 11 of the main UART serial port of the host device is in a pull-up input state and does not affect the high-level sampling, the normal communication between the transmitting pin of the slave UART serial port of the device to be upgraded being upgraded and the receiving pin of the main UART serial port of the host device is ensured. And the transmitting pin 12 of the main UART serial port of the host device is connected to the receiving pins of the slave UART serial ports of multiple devices to be upgraded, so as to realize the normal communication between the transmitting pin 12 of the main UART serial port of the host device and the receiving pins of the slave UART serial ports of multiple devices to be upgraded. In this way, it is beneficial to realize the batch upgrade of multiple devices and improve the user experience.

[0051] Optionally, it further includes: the i-th diode 13. The anode of the i-th diode 13 is connected to the receiving pin 11 of the main UART serial port of the host device, and the cathode is used to be connected to the transmitting pin of the slave UART serial port of the i-th device to be upgraded.

[0052] In this way, the sinking current between the main UART serial port receiving pin 11 of the host device and the slave UART serial port transmitting pins of multiple devices to be upgraded is restricted by the diode 13, so that the sinking current is restricted within a range equivalent to an open circuit. If the slave UART serial port transmitting pin of the device to be upgraded being upgraded is at a low level and the slave UART serial port transmitting pin of the device to be upgraded not being upgraded is at a high level, since the current will not flow from the slave UART serial port transmitting pin of the device to be upgraded not being upgraded into the slave UART serial port transmitting pin of the device to be upgraded being upgraded, the problem that the low level of the slave UART serial port transmitting pin of the device to be upgraded being upgraded rises will not be caused. Since the UART serial port transmitting pin uses the low level as the flag for transmitting information and the main UART serial port receiving pin 11 of the host device is in a pull-up input state and does not affect the high-level sampling, the normal communication between the slave UART serial port transmitting pin of the device to be upgraded being upgraded and the main UART serial port receiving pin 11 of the host device is ensured. Thus, the batch upgrade of multiple devices is realized, improving the user experience.

[0053] Optionally, when the device to be upgraded is in the state of being upgraded, the level of the slave UART serial port transmitting pin of the device to be upgraded is at a low level. When the device to be upgraded is in the state of not being upgraded, the level of the slave UART serial port transmitting pin of the device to be upgraded is at a high level.

[0054] In this way, since the UART serial port transmitting pin uses the low level as the flag for transmitting information and the main UART serial port receiving pin 11 of the host device is in a pull-up input state and does not affect the high-level sampling, the normal communication between the slave UART serial port transmitting pin of the device to be upgraded being upgraded and the main UART serial port 11 of the host device is ensured. Thus, the batch upgrade of multiple devices is realized, improving the user experience.

[0055] Combined with Figure 2 As shown in the figure, another device 2 for batch upgrade provided by an embodiment of the present disclosure is applied to the device to be upgraded and includes: a slave UART serial port transmitting pin 22 and a slave UART serial port receiving pin connection 21. The slave UART serial port transmitting pin 22 is used to be connected to the main UART serial port receiving pin of the host device. Wherein, the anode of the diode 23 is connected to the main UART serial port receiving pin of the host device, and the cathode is connected to the slave UART serial port transmitting pin 22 of the device to be upgraded. The slave UART serial port receiving pin connection 21 is used to be connected to the main UART serial port transmitting pin of the host device.

[0056] Using the device for batch upgrade provided by the embodiments of the present disclosure, by connecting the receiving pin of the main UART serial port of the host device and the transmitting pins 22 of the slave UART serial ports of multiple devices to be upgraded respectively through diodes 23, the sink current between the receiving pin of the main UART serial port of the host device and the transmitting pins 22 of the slave UART serial ports of multiple devices to be upgraded is limited by the diodes 23, so that the sink current is limited within a range equivalent to an open circuit. If the transmitting pin 22 of the slave UART serial port of the device to be upgraded being upgraded is at a low level and the transmitting pin 22 of the slave UART serial port of the device to be upgraded not being upgraded is at a high level, since the current will not flow from the transmitting pin 22 of the slave UART serial port of the device to be upgraded not being upgraded into the transmitting pin 22 of the slave UART serial port of the device to be upgraded being upgraded, the problem that the low level of the transmitting pin 22 of the slave UART serial port of the device to be upgraded being upgraded rises will not be caused. Since the UART serial port transmitting pin uses the low level as the flag for transmitting information, and the receiving pin of the main UART serial port of the host device is in a pull-up input state and does not affect the high-level sampling, the normal communication between the transmitting pin 22 of the slave UART serial port of the device to be upgraded being upgraded and the main UART serial port of the host device is ensured. And the transmitting pin of the main UART serial port of the host device is connected to the receiving pins 21 of the slave UART serial ports of multiple devices to be upgraded, so as to realize the normal communication between the transmitting pin of the main UART serial port of the host device and the receiving pins 21 of the slave UART serial ports of multiple devices to be upgraded. In this way, it is beneficial to realize the batch upgrade of multiple devices and improve the user experience.

[0057] Optionally, it further includes: a diode 23, the anode of which is connected to the receiving pin of the main UART serial port of the host device, and the cathode of which is connected to the transmitting pin 22 of the slave UART serial port of the device to be upgraded.

[0058] In this way, the sink current between the receiving pin of the main UART serial port of the host device and the transmitting pins 22 of the slave UART serial ports of multiple devices to be upgraded is limited by the diode 23, so that the sink current is limited within a range equivalent to an open circuit. If the transmitting pin 22 of the slave UART serial port of the device to be upgraded being upgraded is at a low level and the transmitting pin 22 of the slave UART serial port of the device to be upgraded not being upgraded is at a high level, since the current will not flow from the transmitting pin 22 of the slave UART serial port of the device to be upgraded not being upgraded into the transmitting pin 22 of the slave UART serial port of the device to be upgraded being upgraded, the problem that the low level of the transmitting pin 22 of the slave UART serial port of the device to be upgraded being upgraded rises will not be caused. Since the UART serial port transmitting pin uses the low level as the flag for transmitting information, and the receiving pin of the main UART serial port of the host device is in a pull-up input state and does not affect the high-level sampling, the normal communication between the transmitting pin 22 of the slave UART serial port of the device to be upgraded being upgraded and the main UART serial port of the host device is ensured. Thus, the batch upgrade of multiple devices is realized and the user experience is improved.

[0059] Optionally, when the device to be upgraded is in the upgrading state, the level of the slave UART serial port transmission pin 22 of the device to be upgraded is low. When the device to be upgraded is in the non-upgraded state, the level of the slave UART serial port transmission pin 22 of the device to be upgraded is high.

[0060] In this way, since the UART serial port transmission pin uses the low level as the flag for sending information, and the main UART serial port receiving pin of the host device is in the pull-up input state and does not affect the high-level sampling, the normal communication between the slave UART serial port transmission pin 22 of the device to be upgraded during the upgrade and the main UART serial port of the host device is ensured. Thus, the batch upgrade of multiple devices is realized, improving the user experience.

[0061] Combined with Figure 1 and Figure 3 as shown, an embodiment of the present disclosure provides a method for batch upgrade, including:

[0062] S301, when the Flash of the host device is successfully erased, the device for batch upgrade receives the upgrade file package.

[0063] S302, the device for batch upgrade determines whether the download is successful according to the cyclic redundancy checksum in the upgrade file package.

[0064] S303, when the download is successful, the device for batch upgrade selects the target device to be upgraded from the devices to be upgraded, and sequentially sends the upgrade file package to multiple target devices to be upgraded, so as to realize the sequential batch upgrade of multiple target devices to be upgraded according to the cyclic redundancy checksum in the upgrade file package.

[0065] Wherein, the characteristic information of the target device to be upgraded is the same as the characteristic information in the upgrade file package.

[0066] By using the method for batch upgrade provided in the embodiments of the present disclosure, on the basis of the hardware structure for batch upgrading devices by connecting the receiving pin of the main UART serial port of the host device and the transmitting pins of the slave UART serial ports of multiple devices to be upgraded through diodes respectively, it is determined whether the download is successful according to the cyclic redundancy checksum in the upgrade file package. This is beneficial for the host device to obtain the upgrade file package more accurately. If the download is successful, the target devices to be upgraded are selected from the devices to be upgraded that have the same feature information as the feature information in the upgrade file package, which is beneficial for more accurately batch-selecting the devices to be upgraded that match the feature information of the upgrade file package. And sending the upgrade file package to the target devices to be upgraded is beneficial for accurately and batch-sending the upgrade file package to the matching target devices to be upgraded, enabling the target devices to be upgraded to achieve sequential batch upgrading of multiple target devices according to the cyclic redundancy checksum in the upgrade file package. In this way, it is beneficial to achieve batch upgrading of multiple devices and improve the user experience.

[0067] Optionally, the device for batch upgrade determines whether the download is successful according to the cyclic redundancy checksum in the upgrade file package, including: the device for batch upgrade calculates a reference checksum based on the upgrade program in the upgrade file package and writes it into the Flash (Flash EEPROM Memory). The device for batch upgrade controls the Flash to read the cyclic redundancy checksum in the upgrade file package. When the reference checksum written by the Flash and the cyclic redundancy checksum read are consistent, the device for batch upgrade determines that the download is successful. Or, when the reference checksum written by the Flash and the cyclic redundancy checksum read are inconsistent, the device for batch upgrade determines that the download fails.

[0068] In this way, a reference checksum is calculated based on the upgrade program in the upgrade file package and written into the Flash, and the Flash reads the cyclic redundancy checksum in the upgrade file package. If the Flash reads the same as it writes, it means the download is successful; if not, it means the download fails.

[0069] Optionally, the feature information includes one or more of the following: device machine code, hardware version number, code start address, code end address.

[0070] In this way, only relying on the device machine code, hardware version number, code start address, and code end address as the selection criteria for the target devices to be upgraded, without judging the software information of the devices to be upgraded, the target devices to be upgraded can be quickly selected, reducing the communication times with the devices to be upgraded, thus saving the time for batch upgrading of the devices and improving the efficiency of batch upgrading of the devices, and improving the user experience.

[0071] Optionally, the feature information of the target device to be upgraded is the same as the feature information in the upgrade file package, including: the device machine code of the target device to be upgraded is the same as the device machine code in the upgrade file package; and, the hardware version number of the target device to be upgraded is the same as the hardware version number in the upgrade file package; and, the code start address of the target device to be upgraded is the same as the code start address in the upgrade file package; and, the code end address of the target device to be upgraded is the same as the code end address in the upgrade file package.

[0072] In this way, by relying solely on the selection criteria that the device machine code, hardware version number, code start address, and code end address are the same as those in the upgrade file package for the target device to be upgraded, it is possible to quickly select the target device to be upgraded without judging the software information of the device to be upgraded, reducing the number of communications with the device to be upgraded, thus saving the time for batch device upgrade, improving the efficiency of batch device upgrade, and enhancing the user experience.

[0073] Optionally, the device for batch upgrade sends the upgrade file package to multiple target devices to be upgraded in sequence according to the cyclic redundancy checksum in the upgrade file package, including: the device for batch upgrade determines whether the previous target device to be upgraded has been successfully downloaded according to the cyclic redundancy checksum in the upgrade file package. When the previous target device to be upgraded has been successfully downloaded, the device for batch upgrade upgrades the previous target device to be upgraded through the upgrade program in the upgrade file package and sends the upgrade file package to the next target device to be upgraded. When the previous target device to be upgraded fails to be downloaded, the previous target device to be upgraded abandons the upgrade and sends the upgrade file package to the next target device to be upgraded.

[0074] In this way, when the upgrade file package of the target device to be upgraded is successfully downloaded, if the previous target device to be upgraded is successfully upgraded, the next target device to be upgraded is upgraded; if the previous target device to be upgraded fails to be upgraded, then the target device to be upgraded is skipped and the next target device to be upgraded is directly upgraded. This is beneficial for saving the time for batch device upgrade, improving the efficiency of batch device upgrade, and enhancing the user experience.

[0075] Optionally, the device for batch upgrade determines whether the previous target device to be upgraded has been successfully downloaded according to the cyclic redundancy checksum in the upgrade file package, including: the device for batch upgrade determines that the previous target device to be upgraded has been successfully downloaded when the cyclic redundancy checksum in the upgrade file package is consistent with the reference checksum. The device for batch upgrade determines that the previous target device to be upgraded has failed to be downloaded when the cyclic redundancy checksum in the upgrade file package is inconsistent with the reference checksum. Among them, the reference checksum is calculated by the previous target disk to be upgraded according to the upgrade program in the upgrade file package.

[0076] In this way, the target device to be upgraded reads the cyclic redundancy checksum in the upgrade file package and the reference checksum written through the upgrade program. If they are the same, it is determined that the target upgrade device has been successfully downloaded. If they are different, it is determined that the target upgrade device has failed to download. This is beneficial to making the upgrade process more accurate.

[0077] Combined with Figure 2 and Figure 4 As shown, another method for batch upgrade provided by the embodiments of the present disclosure includes:

[0078] S401. When the device for batch upgrade determines that the device to be upgraded is the target device to be upgraded and the previous target device to be upgraded has completed the upgrade or abandoned the upgrade, it receives the upgrade package file sent by the host device.

[0079] S402. The device for batch upgrade determines whether the download is successful according to the cyclic redundancy check code in the upgrade file package.

[0080] S403. When the download is successful, the device for batch upgrade upgrades through the upgrade program in the upgrade file package and sends an instruction to upgrade the next target device to be upgraded to the host device.

[0081] Among them, the device to be upgraded is determined as the target device to be upgraded, including that the characteristic information of the device to be upgraded is the same as the characteristic information in the upgrade file package. The upgrade file package is sent to the target device to be upgraded by the host device when the Flash erasure is successful and determines whether the download is successful according to the cyclic redundancy checksum in the upgrade file package.

[0082] By using the method for batch upgrade provided by the embodiments of the present disclosure, on the basis of the hardware structure for batch upgrading devices by connecting the main UART serial port receiving pin of the host device and the slave UART serial port sending pins of multiple devices to be upgraded through diodes respectively, after being determined as the target device to be upgraded, if the download is successful, the device to be upgraded with the same characteristic information as that in the upgrade file package is selected as the target device to be upgraded, which is beneficial to more accurately batch-selecting the devices to be upgraded that match the characteristic information in the upgrade file package. Determining whether the download is successful according to the cyclic redundancy checksum in the upgrade file package is beneficial to enabling the device to be upgraded to obtain the upgrade file package more accurately. And the target device to be upgraded receives the upgrade file package one by one, which is beneficial to precisely and batch-sending the upgrade file package to the matching target devices to be upgraded, enabling the target devices to be upgraded to sequentially batch-upgrade multiple target devices according to the cyclic redundancy checksum in the upgrade file package. In this way, it is beneficial to realizing the batch upgrade of multiple devices and improving the user experience.

[0083] Optionally, the feature information includes one or more of the following: device machine code, hardware version number, code start address, and code end address.

[0084] In this way, by relying only on the device machine code, hardware version number, code start address, and code end address as the selection criteria for the target device to be upgraded, without having to judge the software information of the device to be upgraded, the target device to be upgraded can be quickly selected, reducing the number of communications with the device to be upgraded, thus saving the time for batch device upgrade, improving the efficiency of batch device upgrade, and enhancing the user experience.

[0085] Optionally, the feature information of the device to be upgraded is the same as that in the upgrade file package, including: the device machine code of the device to be upgraded is the same as that in the upgrade file package; the hardware version number of the device to be upgraded is the same as that in the upgrade file package; the code start address of the device to be upgraded is the same as that in the upgrade file package; and the code end address of the device to be upgraded is the same as that in the upgrade file package.

[0086] In this way, by relying only on the device machine code, hardware version number, code start address, and code end address that are the same as those in the upgrade file package as the selection criteria for the target device to be upgraded, without having to judge the software information of the device to be upgraded, it can be quickly determined as the target device to be upgraded, reducing the number of communications with the host device, thus saving the time for batch device upgrade, improving the efficiency of batch device upgrade, and enhancing the user experience.

[0087] Optionally, it is determined whether the download is successful according to the cyclic redundancy check code in the upgrade file package, including: the device for batch upgrade calculates a reference checksum based on the upgrade program in the upgrade file package and writes it to the main control board; the main control board of the device for batch upgrade reads the cyclic redundancy checksum in the upgrade file package; the device for batch upgrade determines that the download is successful when the reference checksum written by the main control board is consistent with the read cyclic redundancy checksum; or, the device for batch upgrade determines that the download fails when the reference checksum written by the main control board is inconsistent with the read cyclic redundancy checksum.

[0088] In this way, a reference checksum is calculated based on the upgrade program in the upgrade file package and written; and the cyclic redundancy checksum in the upgrade file package is read. If the read and the written are the same, it means the download is successful, and if they are different, it means the download fails.

[0089] Optionally, after determining that the download fails, it further includes: the device for batch upgrade abandons the upgrade and sends an instruction to upgrade the next target device to be upgraded to the host device.

[0090] In this way, when the upgrade file package of the target device to be upgraded is successfully downloaded, if the previous target device to be upgraded is upgraded successfully, the next target device to be upgraded is upgraded; if the previous target device to be upgraded fails to be upgraded, the target device to be upgraded is skipped, and the next target device to be upgraded is directly upgraded. This helps save the time for batch device upgrades, improve the efficiency of batch device upgrades, and enhance the user experience.

[0091] In practical applications, as Figure 5 shown, an embodiment of the present disclosure provides a method for batch upgrade, including:

[0092] S501. When the Flash of the host device is successfully erased, the host device receives an upgrade file package.

[0093] S502. The host device determines whether the download is successful according to the cyclic redundancy checksum in the upgrade file package.

[0094] S503. When the download is successful, the host device selects a target device to be upgraded from the devices to be upgraded.

[0095] S504. The host device sequentially sends the upgrade file package to multiple target devices to be upgraded, so as to implement sequential batch upgrades of multiple target devices according to the cyclic redundancy checksum in the upgrade file package.

[0096] S505. When the device to be upgraded is determined to be a target device to be upgraded, and the previous target device to be upgraded has completed the upgrade or abandoned the upgrade, the device to be upgraded receives the upgrade package file sent by the host device.

[0097] S506. The device to be upgraded determines whether the download is successful according to the cyclic redundancy check code in the upgrade file package.

[0098] S507. When the download is successful, the device to be upgraded is upgraded through the upgrade program in the upgrade file package.

[0099] S508. The device to be upgraded sends an instruction to upgrade the next target device to be upgraded to the host device.

[0100] Among them, the device to be upgraded is determined to be a target device to be upgraded, including that the characteristic information of the device to be upgraded is the same as the characteristic information in the upgrade file package. The upgrade file package is sent to the target device to be upgraded by the host device when the Flash is successfully erased and it is determined that the download is successful according to the cyclic redundancy checksum in the upgrade file package.

[0101] By adopting the method for batch upgrade provided by the embodiments of the present disclosure, on the basis of the hardware structure for batch upgrading devices achieved by connecting the receiving pin of the main UART serial port of the host device and the transmitting pins of the slave UART serial ports of multiple devices to be upgraded through diodes respectively, after a device to be upgraded is determined as the target device to be upgraded, if the download is successful, the device to be upgraded with the same feature information as that in the upgrade file package is selected as the target device to be upgraded, which is beneficial to more accurately batch-selecting the devices to be upgraded that match the feature information of the upgrade file package. Whether the download is successful is determined according to the cyclic redundancy checksum in the upgrade file package, which is beneficial to enabling the devices to be upgraded to obtain the upgrade file package more accurately. And the target devices to be upgraded receive the upgrade file package one by one, which is beneficial to accurately and batch-sending the upgrade file package to the matching target devices to be upgraded, enabling the target devices to be upgraded to achieve sequential batch upgrade of multiple target devices according to the cyclic redundancy checksum in the upgrade file package. In this way, it is beneficial to achieve batch upgrade of multiple devices and improve the user experience.
