[0059] Some exemplary embodiments of the present disclosure will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Various changes, modifications and equivalents of the methods, devices and / or systems described herein will become apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to those orders set forth herein, but may be changed as becomes apparent after understanding the present disclosure, except for operations that must be performed in a specific order. In addition, descriptions of features known in the art may be omitted for clarity and brevity.

[0060] The following exemplary embodiments of the present disclosure do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0061] In the related art, the upgrade solutions for system control parameters mostly rely on OTA (Over-the-Air) technology. First, the OTA upgrade solution usually requires a network or Bluetooth connection, but it is easily affected by signal interference during the upgrade process, resulting in upgrade failure. Secondly, the OTA upgrade solution usually requires downloading the complete firmware package. Even if only a small number of parameters are modified, the entire machine program needs to be updated, which leads to low upgrade efficiency and a long upgrade time. Thirdly, in the upgrade scenario where it is necessary to disassemble the device and lead out the burning line to write parameters, not only is the upgrade process complicated, but it is also easy to cause equipment damage. Therefore, there is an urgent need for a new system control parameter upgrade solution to improve the efficiency, reliability and security of upgrading the system control parameters.

[0062] Hereinafter, each step of the method in the exemplary embodiment of the present disclosure will be described in more detail with reference to the accompanying drawings and embodiments.

[0063] Figure 1 The figure is a flowchart of a method for updating system control parameters according to an exemplary embodiment of the present disclosure.

[0064] like Figure 1 As shown, in some embodiments, the method for upgrading the system control parameters of the example disclosed herein includes:

[0065] In step S102, an NFC transmission packet sent by a terminal device is received, where the NFC transmission packet includes updated system control parameters.

[0066] In an exemplary embodiment of the present disclosure, the system control parameters include at least one of storage chip parameters, operating logic parameters, sensor feedback parameters, communication interface parameters and protection mechanism parameters. The storage chip parameters include at least one of a storage device serial number, a firmware startup phase sequence, a sensor calibration reference and a communication protocol version. The operating logic parameters include at least one of parameters of a startup control algorithm, a shutdown control algorithm and a control parameter adjustment algorithm. The sensor feedback parameters include environmental sensing parameters and / or firmware operation sensing parameters. The communication interface parameters include internal and external unit communication protocol parameters and / or power phase sequence configuration parameters. The protection mechanism parameters include overload protection threshold parameters and / or safety interlock parameters.

[0067] In an exemplary embodiment of the present disclosure, the system control parameters include parameters required for device operation written into the EEPROM, referred to as EE parameters. The updated EE parameters may be carried in the NFC transmission packet in the form of an EE parameter table.

[0068] In the embodiment of the present disclosure, the target device and the terminal device of the system control parameters to be upgraded are both provided with NFC communication modules. When the preset distance between the target device and the terminal device is less than or equal to the preset distance, NFC transmission packets can be transmitted between the target device and the terminal device.

[0069] In the embodiment of the present disclosure, the target device adopts an NFC controller that supports card emulation and reader / writer dual mode, integrates a radio frequency front end + ARM core, and uses I 2 The C interface is connected to the main control MCU, and the terminal device can reuse the native NFC chip of the mobile phone. The communication distance between the target device and the terminal device is 0-10cm, the transmission rate is 106~424kbps, and the response time is ≤0.3 seconds.

[0070] In the disclosed embodiment, if the target device is an air conditioner, the NFC module can be placed in the air outlet area of ​​the air conditioner to reduce the signal attenuation of the NFC transmission packet caused by metal obstruction. Even when the air conditioner is powered off, the NFC module can draw power from the terminal device's RF field (standby power consumption is less than 1μW) to maintain basic data access, such as fault code reading.

[0071] In step S104, data packet verification is performed on the NFC transmission packet.

[0072] In an exemplary embodiment of the present disclosure, after receiving the NFC transmission packet sent by the terminal device, the target device performs data packet verification on the NFC transmission packet at the physical layer, protocol layer and application layer, wherein the signal integrity check is performed on the NFC transmission packet at the physical layer to reduce the interference of radio frequency interference and data packet loss on the upgrade of system control parameters; the data frame structure compliance check is performed on the NFC transmission packet at the protocol layer to reduce the impact of deformed packet injection on the upgrade of system control parameters; and the device attribute information matching is performed on the NFC transmission packet at the application layer to ensure the authenticity and tamper-proofness of the NFC transmission packet.

[0073] In step S106 , in response to successful verification of the data packet, the system control parameters are updated according to the NFC transmission packet.

[0074] In the disclosed embodiment, system control parameters, which are usually only a few kb in size, are transmitted to the target device via NFC transmission packets, and then the system control parameters are upgraded based on the NFC transmission packets that have been successfully verified as data packets. This realizes the separation of firmware and fixed parameters in the system control parameter upgrade solution. Combined with the characteristics of NFC transmission technology such as being unaffected by network signal interference, strong reliability and strong security, the rapid update of system control parameters is realized, which not only effectively improves the efficiency of R&D debugging and after-sales maintenance, but also has broad application prospects in the fields of smart homes and Internet of Things devices.

[0075] In an exemplary embodiment of the present disclosure, in response to a data packet verification failure, a record of the data packet verification failure is stored in a fault log, and the fault log can interact through a communication link between the target device and the terminal device and be displayed on a user interaction interface of the terminal device.

[0076] In an exemplary embodiment of the present disclosure, Figure 1 Based on the example shown, performing data packet verification on the NFC transmission packet includes: obtaining a CRC value in the NFC transmission packet, performing a data integrity check on the NFC transmission packet according to the CRC value; in response to the NFC transmission packet passing the data integrity check, upgrading the system control parameters according to the NFC transmission packet.

[0077] In the disclosed embodiment, the integrity of the received NFC transmission packet is checked using a CRC value. The CRC (Cyclic Redundancy Check Value) is used to detect whether unexpected errors (such as bit flips) occur during the transmission or storage of the updated system control parameters. The verification process of the above CRC value has a microsecond response and does not require CPU computing resources, thereby further improving the reliability of the system control parameter upgrade.

[0078] In an exemplary embodiment of the present disclosure, Figure 1 Based on the example shown, obtaining the CRC value in the NFC transmission packet, and performing data integrity check on the NFC transmission packet according to the CRC value includes: calculating a calculated value of the CRC value corresponding to the NFC transmission packet.

[0079] In the embodiment of the present disclosure, after the target device receives or reads the NFC transmission packet, it uses the same generating polynomial as the sender to perform exactly the same CRC calculation on the received data block portion (excluding the additional CRC value), calculates a new CRC value (locally calculated CRC value), and compares the locally calculated CRC value with the received CRC value to obtain the pre-stored value of the CRC value in the NFC transmission packet.

[0080] In the embodiment of the present disclosure, the terminal device has an original data block to be sent or stored, selects a generator polynomial (such as CRC-16-CCITT, CRC-32, etc.) agreed upon by both parties (sender and receiver, or writer and reader), uses this generator polynomial to perform a mathematical calculation (modulo 2 division) on the original data, appends the calculated CRC value (i.e., the remainder of the division) to the end of the original data, sends / stores the combination of "original data + CRC value", and determines the data integrity of the NFC transmission packet based on the comparison result between the calculated value of the CRC value and the pre-stored value of the CRC value.

[0081] In the disclosed embodiment, data integrity check is the first step to ensure the security of NFC transmission packets. The received NFC transmission packets are verified using a CRC check algorithm to ensure the integrity of the parameter file and avoid data loss or tampering during transmission.

[0082] In an exemplary embodiment of the present disclosure, Figure 1 Based on the example shown, performing data packet verification on the NFC transmission packet also includes: obtaining device attribute information in the NFC transmission packet, and matching the device attribute information of the NFC transmission packet; in response to the device attribute information in the NFC transmission packet being consistent with the preset matching conditions, upgrading the system control parameters according to the NFC transmission packet.

[0083] In the disclosed embodiment, device attribute information verification may be combined with signature verification (eg, HMAC) to further reduce the probability of attackers tampering with device attribute information.

[0084] In the embodiment of the present disclosure, the control system of the target device reads the SN (Serial Number) and model information of the local target device, and compares the SN and model information of the target device in the NFC data packet respectively. If they do not match, the update is terminated directly, and the error information is written into the fault log and fed back to the display screen of the mobile terminal and the target device. If they match, the update process continues.

[0085] In the embodiment of the present disclosure, the control system of the target device reads the SN of the local target device and compares it with the SN of the target device in the NFC data packet. If there is no match, the update is terminated directly, the error information is written into the fault log and fed back to the display screen of the mobile terminal and the target device. If there is a match, the update process continues.

[0086] In the embodiment of the present disclosure, the control system of the target device reads the model information of the local target device and compares the model information of the target device in the NFC data packet. If there is no match, the update is terminated directly, the error information is written into the fault log and fed back to the display screen of the mobile terminal and the target device. If there is a match, the update process continues.

[0087] In an exemplary embodiment of the present disclosure, Figure 1 Based on the example shown, obtaining the device attribute information in the NFC transmission packet and performing device attribute information matching on the NFC transmission packet includes: reading pre-stored information of local device attribute information.

[0088] In the embodiment of the present disclosure, local device attribute information is pre-stored in a solid-state memory and can serve as a unique identification of the target device.

[0089] In an exemplary embodiment of the present disclosure, Figure 1 Based on the example shown, obtaining the device attribute information in the NFC transmission packet and performing device attribute information matching on the NFC transmission packet further includes: parsing request information of the device attribute information in the NFC transmission packet.

[0090] In the embodiment of the present disclosure, the terminal device writes the device attribute information corresponding to the target device to be upgraded in the NFC transmission package. After receiving and parsing the NFC transmission package, the target device obtains the device attribute information, and then matches it with the local device attribute information to avoid the upgrade process triggered by the mistransmission of the NFC transmission package, thereby improving the reliability and stability of the target device's operation.

[0091] In an exemplary embodiment of the present disclosure, Figure 1 Based on the example shown, obtaining the device attribute information in the NFC transmission package and matching the device attribute information of the NFC transmission package also includes: determining the matching result of the device attribute information of the NFC transmission package based on the matching result between the pre-stored information and the request information, wherein the device attribute information includes model information and / or a unique device identification code.

[0092] In the embodiment of the present disclosure, the pre-stored information is matched with the request information to determine whether the NFC transmission package is received correctly. If correct, the system control parameters are upgraded according to the NFC transmission package. If failed, the matching failure is written into the fault log and fed back to the display screen of the mobile terminal and the target device.

[0093] In an exemplary embodiment of the present disclosure, Figure 1 Based on the example shown, in response to a successful match, upgrading the system control parameters according to the NFC transmission package includes: backing up the local system control parameters to obtain backup system control parameters; in response to completing the backup of the local system control parameters, upgrading the system control parameters according to the NFC transmission package.

[0094] In the embodiment of the present disclosure, before the target device upgrades the system control parameters, the local system control parameters are backed up. The change area can be backed up through partition detection or a complete backup can be performed through a full snapshot. After the backup is completed, the backed up system control parameters and the corresponding timestamps are partitioned and stored.

[0095] In an exemplary embodiment of the present disclosure, Figure 1 Based on the example shown, the method further includes: in response to a failure in upgrading the system control parameters according to the NFC transmission package, performing parameter rollback according to the backup system control parameters.

[0096] In an embodiment of the present disclosure, in response to a failure to upgrade the system control parameters according to the NFC transmission package, the parameters are rolled back according to the backup system control parameters, the most recently backed-up system control parameters are loaded according to the timestamp, and breakpoint recovery is performed to ensure that the target device can still operate normally even if the upgrade fails.

[0097] In the embodiment of the present disclosure, if only the system control parameters (Delta Encoding) in the changed area are backed up, the backup system control parameters corresponding to the changed area are rolled back to the system when the parameters are rolled back.

[0098] In the embodiment of the present disclosure, if a full snapshot is used to perform a complete backup of the system control parameters (Delta Encoding), and multiple historical versions are backed up (the latest 5 versions are stored in a rolling manner), then a specified version rollback is supported.

[0099] In the embodiment of the present disclosure, if the system control parameters of multiple cascaded target devices are upgraded, parameter rollback can be performed on the multiple cascaded target devices in proportion, and parameter rollback of the remaining target devices can be performed by monitoring the operating status of the target parameters after the rollback.

[0100] In an exemplary embodiment of the present disclosure, Figure 1 Based on the shown example, it also includes: sending a fault log during the system control upgrade process to the terminal device, and the fault log includes at least one of an integrity check failure record, a device attribute information matching failure record, a system control upgrade interruption record and a rollback record.

[0101] In the embodiment of the present disclosure, the target device can feed back the fault log to the terminal device through the local area network or core network after completing the upgrade or during the upgrade process, so that the user can intuitively and conveniently view the faults or anomalies that occurred during the upgrade process on the terminal device.

[0103] In the embodiment of the present disclosure, Figure 3As shown, before detecting that the system control parameters of the target device can be upgraded, a prompt message 302 is generated on the user interaction interface of the terminal device 300, for example, "Do you accept the NFC transmission package to upgrade the system control parameters?", and the user is provided with option buttons "Yes / Later" and "No", and then the user is determined to upgrade, upgrade later, or not upgrade based on the user's touch operation on the option button.

[0104] In the embodiment of the present disclosure, Figure 3 As shown, in response to upgrading the system control parameters of the target device, the "percentage" of the "upgrade progress of the system control parameters" is displayed on the terminal device 300, and the user can control the upgrade process to be interrupted or continued by touching the button "Interrupt / Continue".

[0116] In the embodiment of the present disclosure, when the distance between the terminal device and the target device is less than or equal to the preset distance, the NFC transmission packet is triggered for transmission, that is, the system control parameters, which are usually only a few kb in size, are transmitted to the target device through the NFC transmission packet, and then the system control parameters are upgraded according to the NFC transmission packet that has successfully verified the data packet, thereby realizing the separation of firmware and fixed parameters in the system control parameter upgrade solution.
