[0023] The following will combine with the accompanying drawings of the specification to elaborate on the solutions of the embodiments of the present application in detail.

[0024] In the following description, specific details such as specific subsystem structures, interfaces, and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the present application.

[0025] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after. In addition, "multiple" in this article means two or more. In addition, the term "at least one" in this article represents any one of multiple types or any combination of at least two of multiple types. For example, including at least one of A, B, and C can represent including any one or more elements selected from the set composed of A, B, and C.

[0026] Please refer to Figure 1 , Figure 1 It is a schematic flowchart of an embodiment of a camera upgrade method of the present application.

[0027] The camera upgrade method provided by the present application can be applied to a camera and an upgrade device with a Universal Serial Bus (USB) interface. The camera and the upgrade device can be connected through the USB interface. Both the camera and the upgrade device support the Communication Device Class (CDC) protocol. Data related to software upgrade is transmitted between the camera and the upgrade device based on the Communication Device Class protocol of the Universal Serial Bus.

[0028] The following takes the steps executed by the camera as an example for illustration. The method includes:

[0029] Step S110: Sequentially receive at least one data packet sent by the upgrade device related to the target software upgrade.

[0030] Among them, the number of data packets is one or more. All data packets include the upgrade data packet of the target software.

[0031] It is understandable that the camera and the upgrade device can be connected through a USB interface. The upgrade device recognizes the camera as a USB virtual serial port device, and through this virtual serial port, the upgrade device and the camera can communicate. The upgrade device sequentially sends at least one data packet related to the target software upgrade to the camera.

[0032] In some embodiments, all data packets further include an upgrade command packet. Further, the upgrade command may include at least one of a start upgrade command packet and an end upgrade command packet.

[0033] In a specific application scenario, all data packets include an upgrade data packet, a start upgrade command packet, and an end upgrade command packet. The number of upgrade data packets is one or more. The start upgrade command packet and the end upgrade command packet are one each.

[0034] Step S120: Send a response message corresponding to the data packet to the upgrade device.

[0035] Each time the camera receives a data packet, it can execute step S120. Among them, the response message can be used to notify whether the data packet is received successfully.

[0036] When the received upgrade data packet meets the upgrade implementation condition, step S130 is executed. The execution order of step S130 is not limited to after sending the response message.

[0037] Step S130: Store the upgrade data packet in the non-volatile memory.

[0038] Among them, the upgrade data packet can be used to upgrade the target software. After storing the upgrade data packet in the non-volatile memory, the upgrade data packet will not be lost even after the camera is powered off.

[0039] In the above solution, the camera and the upgrade device are connected through a universal serial bus interface. Based on the universal serial bus communication device class protocol, it receives data related to software upgrade sent by the upgrade device and makes a response, realizing the convenient acquisition of upgrade data packets from the device connected through the universal serial bus interface to meet the camera upgrade needs.

[0040] In some embodiments, both the camera and the upgrade device also support the universal serial bus video class protocol (UVC, USB Video Class), and the camera can send video class data to the upgrade device based on the UVC protocol.

[0041] In the above solution, one interface can simultaneously realize the transmission of video data of the camera and the transmission of data related to the upgrade. And the two data transmissions can be carried out simultaneously, and the upgrade data transmission will not affect the normal use of the camera.

[0042] Refer to Figure 2, Figure 2 It is a schematic diagram of an embodiment of the camera upgrade system of the present application.

[0043] The camera upgrade system 20 includes a camera 21 and an upgrade device 22. Among them, the camera 21 and the upgrade device 22 are connected through a universal serial bus interface. Both the camera 21 and the upgrade device 22 support the universal serial bus communication device class protocol.

[0044] The upgrade device 22 can enumerate and recognize the camera 21 as two functional devices, an image device and a USB-to-serial port. Among them, the image device can be used to implement the function of video data transmission, and the USB-to-serial port can be used to implement the upgrade function.

[0045] For the upgrade device 22, a virtual serial port is created in software. Through this virtual serial port, the upgrade device 22 can interact as if it were using a real serial port.

[0046] The upgrade device 22 sequentially sends at least one data packet related to the target software upgrade to the camera 21. The at least one data packet includes the upgrade data packet of the target software. The camera 21 sequentially receives the data packets sent by the upgrade device 22. Each time the camera 21 receives a data packet, it sends a response message corresponding to the data packet to the upgrade device 22. The response message is used to notify whether the data packet has been received successfully;

[0047] When the received upgrade data packet meets the upgrade implementation condition, the camera 21 stores the upgrade data packet in the non-volatile memory.

[0048] In some embodiments, the upgrade device 22 can be a computer. In some embodiments, the camera 21 can be a thermal imaging camera.

[0049] In some cases, the camera 21 and the upgrade device 22 also support the universal serial bus video class protocol.

[0050] In some specific application scenarios, the camera 21 and the upgrade device 22 can simultaneously transmit video data and upgrade-related data.

[0051] In some embodiments, before sending the response message corresponding to the data packet to the upgrade device, the method may further include: performing a first verification on the data packet to obtain a first verification result of the data packet.

[0052] It can be understood that the camera can perform the first verification on any received data packet.

[0053] In some implementation scenarios, information corresponding to the first verification is attached to the upgrade data packet. The camera calculates using the data of the original upgrade data packet to obtain the information to be compared, and compares the information to be compared with the attached information. If the two are consistent, it can be determined that the first verification result is successful verification.

[0054] Further, sending a response message corresponding to the data packet to the upgrade device may include at least one of the following steps: in response to the first verification result being successful verification, sending a response message indicating successful reception of the data packet to the upgrade device; in response to the first verification result being failed verification, sending a response message indicating failed reception of the data packet to the upgrade device.

[0055] Among them, the response message indicating failed reception can be used to prompt the upgrade device to take the data packet with failed reception as the next data packet and resend it.

[0056] In some embodiments, in response to the first verification result being successful verification, the method may further include: in the case where the currently verified successful data packet is an upgrade data packet, storing the upgrade data packet in a volatile memory.

[0057] In a specific application scenario, the camera receives a data packet sent by the upgrade device, performs the first verification on the data packet to obtain the first verification result of the data packet. In the case where the first verification result is successful verification, if the data packet is an upgrade data packet, the upgrade data packet is stored in a volatile memory.

[0058] Further, after storing the upgrade data packet in the volatile memory, a response message indicating successful reception of the data packet is sent to the upgrade device.

[0059] In some embodiments, after the camera determines that the first verification result of the received data packet is successful verification, it can determine the type of the verified successful data packet. If it is an upgrade data packet, the upgrade data packet is stored in a volatile memory.

[0060] In some specific application scenarios, the upgrade data packet can be stored in the memory.

[0061] In some implementation scenarios, storing the upgrade data packet in a non-volatile memory may include: reading the upgrade data packet from the volatile memory and storing it in the non-volatile memory.

[0062] In some specific application scenarios, the upgrade data packet can be read from the memory and stored in a Flash memory.

[0063] In some embodiments, the upgrade implementation condition may include that all upgrade data packets of the target software are successfully received. Thus, all successfully received upgrade data packets can be stored in the non-volatile memory.

[0064] In some implementation scenarios, a data packet sent by the upgrade device can indicate that all upgrade data packets have been sent. The camera can determine whether the current conditions for upgrade implementation are met after receiving this data packet. Exemplarily, identification information is added to the last upgrade data packet to identify it as the last one. Exemplarily, an additional data packet is sent after the last upgrade data packet to indicate that all upgrade data packets have been sent.

[0065] In some embodiments, the upgrade device is configured to send the next data packet after receiving the acknowledgment message indicating that the previous data packet has been successfully received. Therefore, when the camera receives the last data packet, it can be considered that all upgrade data packets have been successfully received.

[0066] In some specific application scenarios, if the camera successfully receives the upgrade data packet with identification information, i.e., the last upgrade data packet, it can be determined that all upgrade data packets for the target software have been successfully received.

[0067] In some specific application scenarios, if the camera successfully receives the additional data packet after the last upgrade data packet, it can be determined that all upgrade data packets for the target software have been successfully received.

[0068] In some embodiments, the upgrade device can send a data packet before sending the upgrade data packet to indicate that the sending of upgrade data packets is about to start.

[0069] In some embodiments, the upgrade device can attach information for verifying all upgrade data packets when sending data packets for validating the data.

[0070] In some implementation scenarios, the verification information for all the foregoing upgrade data packets can be sent in any data packet so that the camera can perform verification. Among them, any data packet can be an upgrade data packet or a data packet sent before sending the upgrade data packet to indicate that the sending is about to start.

[0071] In some embodiments, the data packet sent by the upgrade device can also include an upgrade command packet.

[0072] In some implementation scenarios, the upgrade command packet can include at least one of a start upgrade command packet and an end upgrade command packet. Among them, the upgrade device can send the start upgrade command packet before sending the upgrade data packet, and / or send the end upgrade command packet after sending all upgrade data packets.

[0073] In some embodiments, the start upgrade command packet can be used to provide information for performing a second verification on the upgrade data packets. In the case where the received data packet includes the start upgrade command packet, the upgrade implementation condition can further include passing the second verification.

[0074] Among them, the second verification is a verification for all upgrade data packets, and can be used to determine whether all the currently received upgrade data packets are valid. The method of the second verification is similar to that of the first verification, and reference can be made to the content related to the foregoing first verification, which will not be elaborated here.

[0075] In some implementation scenarios, after receiving the start upgrade command packet, the camera has the information for performing the second verification. This information can be used to perform the second verification on all the received upgrade data packets, and passing the second verification can be used as an upgrade implementation condition.

[0076] Among them, the second verification can be triggered when it is determined that all the upgrade data packets of the target software have been successfully received.

[0077] In some embodiments, after receiving the upgrade command packet, the camera can execute the data processing corresponding to the upgrade command packet, and the data processing corresponding to the upgrade command packet can be used to determine whether the received upgrade data packets meet the upgrade implementation conditions.

[0078] Among them, the data processing corresponding to the start upgrade command packet includes: extracting the total verification information from the start upgrade command packet and storing the total verification information in the volatile memory. The total verification information in the volatile memory is used to perform the second verification on the received upgrade data packets.

[0079] Among them, the data processing corresponding to the end upgrade command packet includes: determining that all the currently received upgrade data packets of the target software have been successfully received, and using the total verification information to perform the second verification on all the received upgrade data packets to obtain a second verification result.

[0080] Furthermore, the camera can, in response to the first verification result being verification success and in the case where the currently verified successful data packet is an upgrade command packet, execute the data processing corresponding to the upgrade command packet.

[0081] In some specific application scenarios, after the camera receives a data packet, it performs the first verification on the data packet. If the verification is successful, it determines the type of the data packet. If it is an upgrade command packet, it executes the data processing corresponding to the upgrade command packet.

[0082] In some specific application scenarios, after receiving a data packet, the camera performs a first verification on the data packet. If the verification is successful and it is determined that the data packet is an end upgrade command packet, it can be determined that all the upgrade data packets of the target software have been successfully received. And the second verification can be triggered. In the case where the result of the second verification passes, the step of storing the upgrade data packet into the non-volatile memory is executed. Further, after the step of storing into the non-volatile memory is completed, a reception success response message corresponding to the end upgrade command packet is sent to the upgrade device.

[0083] Among them, after the step of storing into the non-volatile memory is completed, a reception success response message corresponding to the end upgrade command packet is sent. Thus, the reception success response message can indicate that both the first verification and the second verification pass, which also means that the upgrade data packets of the target software have been successfully transmitted. And, the success response message corresponding to the end upgrade command packet can be used as a flag for powering off the camera. Since the data has been stored in the non-volatile memory, powering off will not cause the loss of the upgrade data packets.

[0084] In the case where the result of the second verification fails, a reception failure response message corresponding to the end upgrade command packet is directly sent to the upgrade device.

[0085] Among them, the reception failure response message corresponding to the end upgrade command packet can indicate that the first verification or the second verification fails. Further, two different response messages can be set for the end command packet, one for feedback to the upgrade device when the first verification fails and the other for feedback to the upgrade device when the second verification fails, so that the upgrade device can determine the specific failure situation.

[0086] If only the first verification fails, the end upgrade command packet can be resent. If the second verification fails, it means that there is an abnormality in the upgrade data packet and resending can be attempted.

[0087] In some embodiments, the total verification information may include at least one of length verification information and content verification information.

[0088] Among them, the length verification information can be used to verify the lengths of all upgrade data packets and determine whether the total length is abnormal. Exemplarily, the length verification information may include the number of upgrade data packets.

[0089] Among them, the content verification information can be used to verify the contents of all upgrade data packets and determine whether the contents are abnormal.

[0090] In some embodiments, the method may further include: upgrading the target software in the non-volatile memory based on the upgrade data packet.

[0091] The target software runs after being loaded into the memory. Receiving data packets and responses will not affect the operation of the target software. Moreover, when upgrading the target software in the non-volatile memory, it will not affect the operation of the target software either, and the upgrade can be achieved while the software is running.

[0092] See Figure 3 , Figure 3 which is a schematic flowchart of another embodiment of the camera upgrade method of the present application.

[0093] In this embodiment, the method steps executed by the camera are taken as an example for illustration.

[0094] After the camera receives a data packet, it performs a first verification on the data packet. If the verification fails, it directly feedbacks a response message indicating reception failure. If the verification is successful, it determines the type of the data packet. If it is an upgrade data packet, it stores the data packet in the volatile memory and then sends a response message indicating successful reception. If it is a start upgrade command packet, it reads the total verification information from it and stores it in the volatile memory, and then sends a response message indicating successful reception. If it is an end upgrade command packet, it uses the total verification information stored in the volatile memory to perform a second verification on all upgrade data packets. If the verification is successful, it stores the upgrade data packets in the non-volatile memory. If the verification fails, it sends a response message indicating reception failure.

[0095] In some embodiments, the data stored in the non-volatile memory may include all received data, not limited to upgrade data packets.

[0096] See Figure 4 , Figure 4 which is a schematic flowchart of yet another embodiment of the camera upgrade method of the present application.

[0097] In this embodiment, the method steps executed by the upgrade device are taken as an example for illustration. In this embodiment, the upgrade device can be configured to send the next data packet after receiving a successful response message, and re-send the data packet corresponding to the failure response message after receiving a failure response message.

[0098] The upgrade package of the target software is divided into multiple upgrade data packets. The upgrade device first sends a start upgrade command packet, and then sequentially and cyclically sends upgrade data packets. After all the upgrade data packets are sent, it sends an end upgrade command packet.
