Hereinafter, some embodiments of the present application will be described in detail with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

Referring to Fig. 1, Fig. 1 is a schematic flowchart of an embodiment of a device upgrade method according to the present application, and the method includes:

Step S101: According to the detected user's target device selection operation, obtain relevant upgrade information of the target device to be upgraded from the relevant upgrade information of the local downstream device, the relevant upgrade information including the identity information of the device and the current version of the device Information, the local downstream device includes a device directly connected to the local device and/or a device connected indirectly.

In this embodiment, the local downstream device includes more than one device directly connected to the local device; also includes more than one device indirectly connected to the local device; also includes more than one device directly connected to the local device and the device indirectly connected to the local device. More than one device, that is, the method of this embodiment may be suitable for upgrading a device with a simple topology, and also for upgrading a device with a complex topology. Correspondingly, the target device to be upgraded includes the device directly connected to the local device and/or the device connected indirectly, that is, the target device may include more than one device directly connected to the local device; it also includes more than one device directly connected to the local device; It also includes more than one device directly connected to the local area and more than one device connected indirectly to the local area. The number of target devices is more than one, for example: one target device, two target devices, three target devices, and so on.

In an embodiment, a plurality of devices are organized into a tree structure according to the connection relationship to generate a device tree, the local (or client) is the root node of the device tree, and the devices on the device tree are divided into intermediate devices and /Or a leaf device, the intermediate device is downwardly connected to a downstream device (including a directly connected downstream device and/or an indirectly connected downstream device), and the leaf device has no downstream device downward.

As shown in Figure 2, the application APP represents the local (user terminal) and is the root node of the device tree. The device tree also includes a remote control, an aircraft (drone) directly connected to the remote control, known peripherals, Unknown peripherals, known mount 1, known mount 2, unknown mount 1 directly connected to the aircraft; remote control and aircraft are intermediate devices, known peripherals, unknown peripherals, known mount 1, already Known mount 2 and unknown mount 1 are leaf devices; the remote control is an intermediate device directly connected to the local area, and the aircraft is an intermediate device directly connected to the local area; Assume that the directly connected upstream device is also the upstream device directly connected to the unknown peripheral; the aircraft is the upstream device directly connected to the known mount 1, and the upstream device directly connected to the known mount 2, and it is also the upstream device directly connected to the unknown mount. 1 Directly connected upstream device; the remote control is an upstream device that is indirectly connected to a known mount 1, is also an upstream device that is indirectly connected to a known mount 2, and is also an upstream device that is indirectly connected to an unknown mount 1; Suppose, unknown peripherals, known mount 1, known mount 2, and unknown mount 1 are leaf devices that are indirectly connected to the local device.

The identity information of the device may be information used to identify the identity of the device, the type of the device, etc., to distinguish different devices and/or each device, such as a unique identification code, a device identification code, an IP address, and so on. For example: device 1, device 2, device 3. The current version information of the device may be the version information of the application currently used by the device. According to the current version information of the device and the latest version information of the device, it can be preliminarily determined whether the device needs to be upgraded and the version information that needs to be downloaded. For example, the current version of the application of device 1 is V1, and the latest version of the application of device 1 is V2. It is preliminarily determined that device 1 needs to be upgraded. The final upgrade depends on whether the user chooses. Upgrade. If device 1 has been used more recently, you can choose to upgrade.

The relevant upgrade information of the local downstream device (that is, the identity information of the device and the current version information of the device) is stored locally, and there are many ways to obtain it. For example, the local user inputs the identity information of the device and the current version information of the device; or, locally The identity information and the starting version information of the device are pre-existing. Whenever the device is upgraded, the current version information of the device is correspondingly modified; or, the upgrade time is pre-appointed, and the connected device pushes its own identity information and current version information to the local at that time ; Or, pre-appoint the upgrade time and connect to the relevant device at the upgrade time; or, the connected device pushes its own identity information and current version information to the local at predetermined time intervals; etc.

The user selects the target device that needs to be upgraded. In this way, the target device can be upgraded according to the user's needs.

Step S102: Download an upgrade package of the corresponding version of the target device according to the current version information of the target device.

According to the current version information of the target device, the upgrade package of the corresponding version of the target device can be downloaded from the server.

For example, the version of the upgrade package of the application program of the device 1 on the server is V1 and V2, and according to the current version of the application program of the device 1 is V1, it is determined to download the upgrade package corresponding to the version V2 of the target device.

In another example, the version of the upgrade package of the application program of the device 1 on the server is V1, V2, and V3. According to the current version of the application program of the device 1 is V1, it is determined to download the upgrade package corresponding to the version V3 of the target device.

Step S103: The upgrade package of the corresponding version of the target device and the identity information of the target device are transmitted to the local downstream device, so that the local downstream device will transfer the target device to the target device according to the identity information of the target device. The upgrade package of the corresponding version is transmitted to the target device, so that the target device obtains the upgrade package of the corresponding version.

The local downstream equipment includes equipment directly connected to the local and/or indirectly connected equipment, the target equipment to be upgraded includes equipment directly connected to the local and/or indirectly connected equipment, and the upgrade package of the corresponding version of the target device is combined with The identity information of the target device is transmitted to the local downstream device, so that the local downstream device transmits the upgrade package of the corresponding version of the target device to the target device according to the identity information of the target device, and specifically transmits There are many ways and transmission details, as long as the local downstream device is finally made to transmit the upgrade package of the corresponding version of the target device to the target device, so that the target device can obtain the upgrade package of the corresponding version.

For example: if it is transferred from device 1 to device 2, and device 2 needs to be upgraded (that is, the identity information of the target device has device 2), then device 2 obtains the corresponding upgrade package (device 2 does not need to be upgraded, so this step is ignored), and then All interfaces of device 2 that can be connected to other devices send the upgrade package of the corresponding version of the target device and the identity information of the target device (because device 2 has already obtained the corresponding upgrade package, when device 2 continues to transmit, the upgrade package of the corresponding version of device 2 can be sent And the identity information of the device 2 is deleted), if the interface is connected to a downstream device, the downstream device can receive the upgrade package corresponding to the target device version and the identity information of the target device. If the interface is not connected to the downstream device, it will be transmitted to This ends.

Another example: if you transfer from device 1 to device 2, device 2 can detect which interfaces are connected to downstream devices, device 2 does not need to be upgraded, and sends the upgrade package of the target device's corresponding version to the interface where device 2 is connected to the downstream device. The identity information of the target device.

Another example: if it is transmitted from device 1 to device 2, device 2 saves the identity information of the downstream device of device 2, and device 2 will send targeted information to the device according to the identity information of the downstream device of device 2 and the identity information of the target device. Directly connected downstream devices (that is, downstream devices that have a direct or indirect connection with the target device) transmit, but not to all directly connected downstream devices.

Step S104: After the target device obtains the upgrade package of the corresponding version, control the target device to upgrade according to the upgrade package of the corresponding version of the target device.

According to the detected target device selection operation of the user, the embodiment of the application obtains the relevant upgrade information of the target device to be upgraded from the relevant upgrade information of the local downstream device. The relevant upgrade information includes the identity information of the device and the current status of the device. Version information, the local downstream device includes devices directly connected to the local device and/or devices connected indirectly; according to the current version information of the target device, downloading the upgrade package corresponding to the target device's version; uploading the target device The upgrade package of the corresponding version and the identity information of the target device are transmitted to the local downstream device, so that the local downstream device transmits the upgrade package of the corresponding version of the target device to the local downstream device according to the identity information of the target device. The target device enables the target device to obtain the upgrade package of the corresponding version; when the target device obtains the upgrade package of the corresponding version, the target device is controlled to upgrade according to the upgrade package of the corresponding version of the target device. According to the detected user's selection operation, the identity information and current version information of the target device to be upgraded are obtained from the relevant upgrade information of the local downstream device, and the upgrade of the corresponding version of the target device is downloaded according to the current version information of the target device Package, which transmits the upgrade package of the corresponding version of the target device and the identity information of the target device to the local downstream device, so that the local downstream device transmits the upgrade package of the corresponding version of the target device to the target device, so that the target device obtains the upgrade package of the corresponding version ; When the target device obtains the upgrade package of the corresponding version, the target device is controlled to upgrade. In this way, the target device selected by the user and directly connected to the local and/or indirectly connected to the user can be upgraded according to the user’s needs. It is suitable for the upgrading of equipment with complex topological structure, and also provides technical support for the new requirements of upgrading "the number of upgraded equipment is large, the upgrade plan needs to maintain scalability, and the equipment can be plugged and unplugged at any time".

Under normal circumstances, the interface on the device may be connected to the downstream device, or may not be connected to the downstream device; it may be connected to the downstream device during this period of time, and the downstream device may not be connected to the downstream device in another period of time; it may be connected to the device locally. The distance is too far, and the user has no way to figure out the connection between the devices; it is possible that the situation is urgent or special equipment is plugged and unplugged at any time; etc., in order to enable the user to select the target device in a targeted manner when selecting the target device, steps Before S101, it also includes:

Step S105: Obtain the relevant upgrade information of the local downstream device.

Specifically, the relevant upgrade information of the local downstream device can be obtained through a heartbeat packet. In this embodiment, the heartbeat packet is a self-defined command word that is periodically notified to the other party of its own state between the device and the local, and is sent at a certain time interval, similar to a heartbeat, so it is called a heartbeat packet. That is, each connected device pushes a heartbeat packet to the local, so that the local device updates the relevant upgrade information of the local downstream device according to whether the heartbeat packet pushed by each device exists. In this way, the local does not need to pay attention to each device. The connection status of the equipment can meet the new requirements of the upgrade.

Furthermore, through the heartbeat package push method, each device can be organized to form an upgrade management list in the local APP, including the identity information of each device, whether each device needs to be upgraded, and the latest version that can be upgraded. And notify the user; update the upgrade management list according to the update pushed by the heartbeat package of each device; add a new heartbeat package, add the relevant upgrade information of the corresponding device, and delete the corresponding device when the heartbeat package expires. Relevant upgrade information); users can select the target device they need to upgrade to form a list of upgrades, and trigger the upgrade with one click.

In an embodiment, step S105 may specifically include: sub-step S1051 and sub-step S1052.

Sub-step S1051: Obtain the registration command of the local downstream device, the registration command is sent by the local downstream device to register with the upstream device directly connected and/or indirectly connected with the local downstream device.

Sub-step S1052: Obtain the relevant upgrade information of the local downstream device through the registration command of the local downstream device.

The local downstream device may register with the upstream device directly connected to the local downstream device, for example: when the local downstream device is a leaf device, it may register directly with the local; another example: sequentially with the local The connected devices are device 1, device 2, and device 3. Device 3 registers with device 2, device 2 registers with device 1, and device 1 registers locally; among them, when device 2 registers with device 1, its registration command can be one And carry the relevant upgrade information of the device 3. Similarly, when the device 1 registers locally, its registration command can also carry the relevant upgrade information of the device 3 and the device 2.

The local downstream device may also register with the upstream device indirectly connected with the local downstream device, for example: register with the upstream device indirectly connected with the local downstream device, if the upstream device is not local, no Send a response message and continue forwarding it directly to the upstream device until it is forwarded locally. The local feedback response message informs the downstream device that it has received the registration command locally and obtains the relevant upgrade information of the downstream device.

The local downstream device may also register with the upstream device directly connected and indirectly connected with the local downstream device. For example: first register with the upstream device directly connected to the local downstream device, and after the registration is successful, register with the upstream device indirectly connected to the local downstream device until it is forwarded to the local, and the local feedback response message . In this way, each device can obtain relevant upgrade information of all its downstream devices, and provide technical support for subsequent purposeful and targeted forwarding.

In an embodiment, the registration command includes a device registration command and/or a transfer registration command, and the device registration command is the device registration of the local downstream device with the upstream device directly connected to the local downstream device. The registration command sent, the transmission registration command is a registration command sent by the local downstream device to transmit and register with the upstream device directly connected and indirectly connected with the local downstream device.

In an embodiment, before obtaining the registration command of the local downstream device in sub-step S1051, it may further include: controlling the local downstream device to send the local downstream device to the upstream device directly connected to the local downstream device. The device registration command enables the upstream device directly connected to the local downstream device to obtain the relevant upgrade information of the local downstream device.

Specifically, the process of device registration may be: generating a registration data packet in a predetermined format; controlling the local downstream device to send the registration data packet to an upstream device directly connected to the local downstream device; controlling the and The upstream device directly connected to the local downstream device receives the registration data packet.

Wherein, the controlling the local downstream device to send a device registration command to an upstream device directly connected to the local downstream device further includes: controlling the local downstream device to a downstream device connected to the local at a predetermined time interval. The upstream device directly connected to the device sends the device registration command.

Through the above method, it is possible to meet the new requirements of the upgrade "the upgrade solution needs to maintain scalability and be able to handle the plugging and unplugging of equipment at any time".

In another embodiment, before obtaining the registration command of the local downstream device in sub-step S1051, it may further include: controlling the local downstream device to directly connect to the upstream device directly connected to the local downstream device and indirectly The connected upstream device sends a transmission registration command, so that each of the local downstream devices obtains relevant upgrade information of all its downstream devices. Wherein, the local downstream device is controlled to send a transmission registration command to the upstream device directly connected to the local downstream device and the upstream device indirectly connected at a predetermined time interval.

In a specific implementation manner, the controlling the local downstream device to send a transmission registration command to the upstream device directly connected to the local downstream device and the indirectly connected upstream device may also include: successfully registering with the device Then, the local downstream device is controlled to send a transmission registration command to the upstream device directly connected to the local downstream device and the upstream device indirectly connected.

Specifically, the process of transferring registration may be: generating a registration data packet in a predetermined format; controlling the local downstream device to send the registration data packet to the upstream device directly connected to the local downstream device and the upstream device indirectly connected Send until it is sent to the local; control the local to return a response data packet to the downstream device directly connected to the local.

Wherein, the data content of the registration data packet includes the command identification code, the device name, the device identification code, the device type, and the directly connected upstream device identification code.

Wherein, the command identification code includes a device registration command identification code or a transmission registration command identification code.

In an embodiment, step S102 may specifically include: downloading an upgrade package of the corresponding version of the target device according to the detected upgrade trigger operation of the user and the current version information of the target device. For example, after the user selects the target device to be upgraded and forms the list that needs to be upgraded, the upgrade is triggered with one click, and based on the detected upgrade trigger operation of the user and the current version information of the target device, download the corresponding version of the target device Upgrade package.

In an embodiment, before step S103, it may further include: sending a transmission preparation command to the target device. The relevant upgrade information of the local downstream devices and the connection relationship between the local downstream devices are stored in the local in advance. Wherein, the content of the preparation transmission command includes the identity information of the device, whether the device itself is upgraded, and whether the downstream device of the device is upgraded. In this way, on the one hand, the device can be prepared for upgrade, and on the other hand, the local downstream device can be targeted and purposefully transmitted to the target device with the upgrade package corresponding to the version of the target device.

For example: as shown in Figure 3, there are currently 4 downstream devices connected to the local area. According to the connection with the local area, they are device A (directly connected to the local), device B (directly connected to the device A), and device C (directly connected to device A) and device D (directly connected to device B); the content of the prepared transmission command is: device A, device A is upgraded (that is, device A is the target device), and the downstream device of device A is upgraded; device B , Device B is not upgraded, and the downstream device of device B is upgraded; Device C, device C is upgraded (ie, device C is the target device), and the downstream device of device C is not available; device D, device D is upgraded (ie, device D is the target device), No downstream equipment of equipment D. When the upgrade package of the corresponding version of the target device is transmitted to device A, because device A is upgraded, device A obtains the upgrade package of the corresponding version of device A, and then forwards the upgrade package of the corresponding version of the target device to devices B and C directly connected to device A ; After device B receives, because device B is not upgraded, but the downstream device of device B is upgraded, device B directly forwards device D connected to device B; after device C receives, because device C is upgraded, device C has no downstream device ( That is, device C is a leaf device), device C obtains the upgrade package of the corresponding version of device C, and no longer forwards it; after device D receives it, because device D is upgraded, device D has no downstream devices, and device D obtains the upgrade package of the corresponding version of device D , No longer repost.

In an embodiment, in step S104, the controlling the target device to upgrade according to the upgrade package of the corresponding version of the target device may further include: sending an upgrade trigger command to the downstream device directly connected to the local device; The downstream devices directly connected to the local device respectively trigger the target device so that the target device is upgraded according to the upgrade package of the corresponding version of the target device.

At this time, the method may further include: receiving the upgrade progress pushed by the downstream device directly connected to the local device until the upgrade of the target device is completed.

In most cases, the number of the target devices is more than two, and the details of step S103 are specifically described below.

Step S103, the transmission of the upgrade package of the corresponding version of the target device and the identity information of the target device to the local downstream device may include: sub-step S1031 and sub-step S1032.

Sub-step S1031: Parallel transmission of two or more upgrade packages of the corresponding versions of the target device and the identity information of the target device to the downstream device directly connected to the local device.

Sub-step S1032: According to the identity information of the target device, control the downstream device directly connected to the local device to perform a matching operation, so that the target device obtains the upgrade package of the corresponding version, and each of the local downstream devices The device saves the identity information of the downstream device.

When the number of the target device is more than two, parallel transmission to the downstream device directly connected to the local device can avoid the sequential transmission due to the large number of upgrade devices and excessively prolong the upgrade time, and can meet the new requirements of the upgrade. "The number of upgrade devices is large. ".

The target device to be upgraded can be divided into the following situations: the first target device includes the target leaf device (the target device does not need to forward the upgrade package after receiving the corresponding version), and the second target device includes the target intermediate device (target After the device receives the upgrade package of the corresponding version, it determines whether it needs to be forwarded according to whether its downstream device needs to be upgraded), the third type of target device includes the target leaf device and the target intermediate device, and the above-mentioned first and second situations can be combined Carry out implementation.

The following uses a remote controller and an unmanned aerial vehicle system as an example to illustrate the method of the embodiment of the present application in detail.

Refer to Figure 4, which is a schematic diagram of the application process of the device upgrade method of the present application in the remote control and UAV system, including the following steps:

1. The device pushes the heartbeat package (including the related upgrade information of the device) to the local APP through registration, and organizes the devices of the drone locally to form an upgrade management list in the local APP. The content of the upgrade management list can include Whether each device needs to be upgraded (determined according to the current version information of the device and the latest upgradeable version corresponding to the device), the latest upgradeable version corresponding to the device, and notify the user of it;

2. The local APP does not need to pay attention to the connection status of each device, but only needs to update the upgrade management list according to whether the heartbeat packet push of each device exists;

3. Users can select the equipment they need to upgrade to form an upgrade list, and trigger the upgrade with one click;

4. After the local APP receives the user-triggered upgrade operation, it downloads the upgrade package of the corresponding version of the target device in the list according to the user's need to upgrade list;

5. After the download is complete, the local APP sends the preparation transmission command to the target devices in the list to be upgraded in parallel, and transmits the upgrade package to these target devices in parallel, without the need for sequential transmission and upgrade;

6. After the transmission of the upgrade package of the corresponding version of all target devices to be upgraded is completed, the local APP sends an upgrade trigger command to the downstream device directly connected to the local (also called direct downstream device), and the direct downstream device triggers the upgrade list separately The target device in the device is upgraded internally, and the local APP receives the upgrade progress pushed by the direct downstream device until the upgrade of all target devices is completed.

In the first step, the device pushes heartbeat packets through registration, which can organize multiple devices to solve the new requirements of device upgrades. "The number of upgrade devices is large, the upgrade plan needs to maintain scalability, and it can handle the plugging and unplugging of devices at any time. "lay the foundation. A typical upgrade scenario for consumer-grade drones is shown in Figure 5, and a typical upgrade scenario for industry-grade drones is shown in Figure 2. Both upgrade topological diagrams present a tree structure, and the embodiments of this application are collectively referred to as a device tree. The local APP is the root node of the device tree; each device is a tree node; the device without downstream devices is a leaf device (leaf node); the device with downstream devices is an intermediate device (intermediate node). For a typical device tree for consumer drones (see Figure 5), the remote control is an intermediate device, and the aircraft is a leaf device. For a typical device tree of an industry-level UAV (see Figure 2), the remote control and the aircraft are both intermediate devices, and the peripherals and mounts are leaf devices.

In order to transform the physical device tree into a logically processable device tree, the embodiment of this application uses "device registration" and "transmission registration". Device registration can be: the downstream device registers with the directly connected upstream device (direct upstream device), so that each device node knows the existence of its directly connected downstream device (direct downstream device); transmission registration can be: device registration is successful Later, the downstream device registers with the directly connected upstream device (direct upstream device) and indirectly connected upstream device (indirect upstream device), so that each device node knows the existence of all its downstream devices. Both of these registrations are sent by the downstream device to the upstream device in the form of a heartbeat packet, that is, at a frequency of 1 Hz. If the heartbeat packet for registration of a downstream device is received for the first time, the device will be added to the local APP upgrade management list; if the heartbeat packet of a downstream device has timed out, it will exceed a certain period of time (for example: specific implementation) The time can be 5 seconds) The local APP has not received the heartbeat packet for registration of the downstream device, and the local APP considers that the device is not connected, and the local APP removes the device from the upgrade management list. Therefore, the method of "pushing the heartbeat package for registration" makes the local APP need not care about the connection status of each device, can achieve the scalability of the upgrade plan, and can cope with the plugging and unplugging of the device at any time.

In addition, the contents of the local APP upgrade management list may include: device type, device ID, status of whether the device needs to be upgraded, and the latest version of the device on the server. Among them, the status of whether to upgrade is the comparison between the current version of the device and the latest version on the server. If the current version of the device is smaller, it needs to be upgraded, otherwise, it is not necessary to upgrade.

In this embodiment, the specific implementation of device registration is shown in Figure 6: After downstream device C connects to upstream device B, C needs to send a registration data packet in the specified format and upload it to upstream device B; after upstream device B receives it, it returns Send the registration data packet in the same format and deliver it to the downstream device C. After this process is over, it is deemed that the downstream device C has successfully registered with the upstream device B's device. Among them, the register command data format can be seen in Table 1.

Table 1 Register command data format

Data content	Remark
Command id	Device registration command id, or transfer registration command id
Equipment name	The name of the device, string
Device id	The id of the device itself
Equipment type	The type of the device, enumerated value
Communication id	In this device registration, the upstream device id

In this embodiment, refer to Figure 6 for the specific implementation of the transmission registration. After the downstream device C successfully registers with the device of the upstream device B, the downstream device C sends a registration data packet in the specified format to the upstream device B (the difference between the registration command id and the device Registered registration command id); after the upstream device B receives it, it only feeds back the response data packet to the downstream device C; at the same time, the upstream device B forwards the registration data packet of the downstream device C to the root node A; after the root node A receives it, Only the response data packet is fed back to device B. After this process is over, it is deemed that the downstream device C has successfully registered for transmission to the direct upstream device and the indirect upstream device.

In the second step, update the upgrade management list of the local APP according to the heartbeat package pushed for registration. In the third step, the user can select the target device that he needs to upgrade to form a list to be upgraded, and trigger the upgrade with one click. It should be noted here that the user selects the target device that can be upgraded from the upgrade management list of the local APP. If the device is already the latest version of the device, the interface is grayed out and the user cannot select it. After forming the list to be upgraded, the user clicks one key to upgrade. In step 4, download the upgrade package of the corresponding version of the target device in the list to be upgraded.

In step 5, the local APP transfers the upgrade package corresponding to the target device in parallel to the target device in the list to be upgraded. In the existing consumer-grade UAV APP upgrade solution, the APP upgrades the devices one by one, and transmits and upgrades sequentially. In the solution of the embodiment of this application, the local APP sends a transmission preparation command in parallel to the target devices in the list to be upgraded, and then transmits the Upgrade package of the target device. If multiple target devices are included in the upgrade list, the above process is parallel. In this embodiment, the specific implementation of sending the prepare transmission command can be seen in Figures 7-11. For industry-level drones, commonly used upgrade scenarios can include: scenario one, local APP upgrades a device alone; scenario two, local APP Upgrade all devices; Scenario 3: Local APP upgrades a certain leaf device in all devices; Scenario 4: Local APP upgrades an intermediate device in all devices; Scenario 5: Local APP upgrades a certain group of devices in all devices. The local APP serves as the root node of the device tree, and sends a transmission preparation command downward. The preparation transmission command in the embodiment of this application is different from the preparation transmission command of the consumer-grade UAV APP upgrade solution, and requires two more flag parameters. For the command format of the preparation transmission command in this embodiment, see Table 2.

C device is an intermediate device that is indirectly connected to the local device, and E device and F device are Leaf devices that are indirectly connected to the local device; the E device and the F device are downstream devices directly connected to the C device, and the intermediate device B device is included between the C device and the local device. The value of the prepared transmission command can be seen in Table 7.

After the preparation for transmission command is successfully sent, the local APP transmits the upgrade package to the target device that needs to be upgraded; the device that does not need to be upgraded only participates in the process of transferring the upgrade package. Since the actual physical link between the local APP and each target device that needs to be upgraded is different, the transmission method may also be different, so I won't repeat it here. After all the upgrade package transmissions are completed successfully, proceed to step 6: The local APP sends an upgrade trigger command to the direct downstream device, and the direct downstream device will trigger the target device in the list to be upgraded to perform internal upgrade, and the local APP receives the direct downstream device. The upgrade progress pushed by the device until the end of the upgrade.

In the embodiment of the present application, the target device that needs to be upgraded becomes a node of the device tree by means of device registration and transmission registration, and the local APP is the root node of the device tree. Every time a device is plugged in (whether it is a peripheral on the remote control or mounted on an airplane), the local APP will add the device to the upgrade management list according to the heartbeat packet used for registration of the device; if the device If it is removed, the local APP deletes the device from the upgrade management list according to the timeout of the heartbeat packet for registration of the device. As long as all devices connected to the device tree of the embodiment of the present application meet the registration implementation and data standards, the local APP can implement the upgrade of the device, and can conveniently handle the plugging and unplugging of the device, while maintaining the scalability of the upgrade solution. After the user triggers the upgrade, the local APP will send upgrade instructions to these target devices in the device tree in parallel and transmit upgrade packages to these target devices in parallel according to the upgrade list formed by the user's selection. After the upgrade package transmission of all target devices that need to be upgraded is completed, The local APP also triggers the internal upgrade of these target devices. Therefore, users only need to select the target device that needs to be upgraded, and they can upgrade with one click. At the same time, parallel transmission replaces the sequential transmission upgrade in the existing scheme, which can greatly reduce the upgrade time in the case of multiple devices.

In summary, through the solutions of the embodiments of this application, the local APP can well meet the new upgrade requirements "large number of upgraded equipment, maintain scalability, and be able to handle the plugging and unplugging of equipment at any time", so as to achieve the upgrade of industry-level drones. Goal: Users can select the target device they need to upgrade from among multiple devices, and perform one-click upgrade.
