Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, fig. 1 is a schematic flowchart of an embodiment of a method for upgrading a device according to the present application, where the method includes:

step S101: according to the detected target equipment selection operation of the user, acquiring related upgrading information of target equipment to be upgraded from related upgrading information of local downstream equipment, wherein the related upgrading information comprises identity information of the equipment and current version information of the equipment, and the local downstream equipment comprises equipment directly connected with the local and/or indirectly connected with the local.

In this embodiment, the local downstream device includes more than one device directly connected to the local; also include more than one device indirectly connected to the local; the method also comprises more than one device directly connected with the local and more than one device indirectly connected with the local, namely the method of the embodiment can be suitable for upgrading the devices with simple topological structures and also suitable for upgrading the devices with complex topological structures. Correspondingly, the target device to be upgraded comprises a device directly connected with the local and/or a device indirectly connected with the local, that is, the target device may comprise more than one device directly connected with the local; also include more than one device indirectly connected to the local; also includes more than one device directly connected with the local and more than one device indirectly connected with the local. The number of target devices is more than one, for example: one target device, two target devices, three target devices, etc.

In an embodiment, a plurality of devices are organized into a tree structure according to connection relationships to generate a device tree, a local (or user side) is a root node of the device tree, the devices on the device tree are divided into intermediate devices and/or leaf devices, the intermediate devices are connected with downstream devices (including directly connected downstream devices and/or indirectly connected downstream devices) downwards, and the leaf devices are not connected with downstream devices downwards.

As shown in fig. 2, the application APP represents a local (user side) and is a root node of an equipment tree, the equipment tree further includes a remote controller, an airplane (unmanned aerial vehicle), a known peripheral device, an unknown peripheral device, a known mount 1, a known mount 2, and an unknown mount 1, which are directly connected to the remote controller; the remote controller and the airplane are intermediate devices, and the known peripheral device, the unknown peripheral device, the known mount 1, the known mount 2 and the unknown mount 1 are leaf devices; the remote controller is an intermediate device directly connected with the local, and the airplane is an intermediate device indirectly connected with the local; the remote controller is an upstream device directly connected with the airplane, a known peripheral device and an unknown peripheral device; the aircraft is an upstream device directly connected to the known mount 1, also an upstream device directly connected to the known mount 2, also an upstream device directly connected to the unknown mount 1; the remote controller is an upstream device indirectly connected with the known mount 1, also an upstream device indirectly connected with the known mount 2, also an upstream device indirectly connected with the unknown mount 1; the known peripheral, the unknown peripheral, the known mount 1, the known mount 2, and the unknown mount 1 are leaf devices indirectly connected to the local.

The identity information of the device may be information for identifying the device identity, the device type, etc. to distinguish different devices and/or each device, such as a unique identification code, a device identification code, an IP address, etc. For example: device 1, device 2, device 3. The current version information of the device may be version information of an application currently used by the device. According to the current version information of the equipment and the latest version information of the equipment, whether the equipment needs to be upgraded or not and the version information needing to be downloaded can be preliminarily determined. For example, the current version of the application program of the device 1 is V1, the latest version of the application program of the device 1 is V2, it is preliminarily determined whether the device 1 needs to be upgraded, and whether the upgrade is finally selected by the user, and if the device 1 is not used much recently, the upgrade may not be temporarily performed, and if the device 1 is used much recently, the upgrade may be selected.

The upgrade information (i.e. the identity information of the device and the current version information of the device) related to the local downstream device is stored locally, and the obtaining manner is many, for example: inputting identity information of equipment and current version information of the equipment at a local user; or, the identity information and the initial version information of the local prior equipment correspondingly modify the current version information of the equipment every time the equipment is upgraded; or, appointing upgrading time in advance, and pushing the identity information and the current version information of the connected equipment to the local at the time; or, appointing the upgrading time in advance, and connecting the relevant equipment at the upgrading time; or the connected equipment pushes the identity information and the current version information of the connected equipment to the local at preset time intervals; and so on.

The user selects the target equipment needing to be upgraded, and the target equipment can be upgraded according to the requirements of the user through the mode.

Step S102: and downloading the upgrade package of the version corresponding to the target equipment according to the current version information of the target equipment.

And according to the current version information of the target equipment, downloading the upgrade package of the version corresponding to the target equipment from a server.

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

For another example: the versions of the upgrade package of the application program of the device 1 on the server are V1, V2 and V3, and according to the fact that the current version of the application program of the device 1 is V1, the upgrade package of the version V3 corresponding to the target device is determined to be downloaded.

Step S103: and transmitting the upgrade package of the version corresponding to the target equipment and the identity information of the target equipment to the local downstream equipment, so that the local downstream equipment transmits the upgrade package of the version corresponding to the target equipment according to the identity information of the target equipment, and the target equipment acquires the upgrade package of the corresponding version.

The method includes that a local downstream device includes a device directly connected with the local and/or a device indirectly connected with the local, a target device to be upgraded includes a device directly connected with the local and/or a device indirectly connected with the local, an upgrade package of a version corresponding to the target device and identity information of the target device are transmitted to the local downstream device, the local downstream device transmits the upgrade package of the version corresponding to the target device according to the identity information of the target device, specific transmission modes and transmission details can be various, as long as the local downstream device transmits the upgrade package of the version corresponding to the target device, and the target device obtains the upgrade package of the corresponding version.

For example: if the device 2 needs to be upgraded (that is, the identity information of the target device has the device 2) after being transmitted from the device 1 to the device 2, the device 2 acquires the corresponding upgrade package (the step is omitted if the device 2 does not need to be upgraded), then sends the upgrade package of the version corresponding to the target device and the identity information of the target device to all interfaces of the device 2 that can be connected to other devices (because the device 2 already acquires the corresponding upgrade package, the upgrade package of the version corresponding to the device 2 and the identity information of the device 2 can be deleted when the device 2 continues to transmit), if the interface is connected to a downstream device, the downstream device can receive the upgrade package of the version corresponding to the target device and the identity information of the target device, and if the interface is not connected to the downstream device, the transmission is terminated.

For another example: if the upgrade package is transmitted from the device 1 to the device 2, the device 2 can detect which interfaces are connected with downstream devices, the device 2 does not need to upgrade, and sends the upgrade package of the version corresponding to the target device and the identity information of the target device to the interfaces of the device 2 connected with the downstream devices.

For another example: if the identity information of the downstream device of the device 2 is stored in the device 2, the device 2 performs targeted transmission to the directly connected downstream device (i.e. the downstream device having a direct or indirect connection relationship with the target device) according to the identity information of the downstream device of the device 2 and the identity information of the target device, but not to all the directly connected downstream devices.

Step S104: and after the target equipment acquires the upgrade package of the corresponding version, controlling the target equipment to upgrade according to the upgrade package of the version corresponding to the target equipment.

In general, the interface on the device may or may not be connected with the downstream device; it is possible that during this time period downstream equipment is connected, and during another time period no downstream equipment is connected; it is possible that the local device is too far away from the device, and the user has no way to know the connection between the devices; emergency or special equipment can be plugged at any time; and the like, in order to enable the user to specifically select the target device when selecting the target device, before step S101, the method further includes:

step S105: and acquiring related upgrading information of the local downstream equipment.

Specifically, the related upgrade information of the local downstream device may be acquired by a heartbeat packet. In this embodiment, the heartbeat packet is a self-defined command word that notifies the other party of its own state at regular time in the device and the local, and is sent at a certain time interval, similar to a heartbeat, and is called a heartbeat packet. The method can make the local not pay attention to the connection state of each device, and can meet the new requirements of upgrading, namely that an upgrading scheme needs to maintain expansibility and can cope with equipment plugging and unplugging at any time.

Furthermore, through a heartbeat package pushing mode, all the devices can be organized, an upgrade management list is formed in a local APP, the upgrade management list comprises identity information of each device, the state of whether each device needs to be upgraded or not, and the upgradable latest version, and the upgrade management list is notified to a user; updating the upgrade management list according to the update pushed by the heartbeat packet of each device; if a heartbeat packet is newly added, relevant upgrading information of corresponding equipment is newly added, and if the heartbeat packet is overtime, relevant upgrading information of corresponding equipment is deleted); the user can select the target equipment needing upgrading to form a list needing upgrading, and the upgrading is triggered by one key.

In an embodiment, step S105 may specifically include: substeps 1051 and substep S1052.

Substep S1051: acquiring a registration command of the local downstream device, wherein the registration command is sent by registering the local downstream device with an upstream device directly connected and/or indirectly connected with the local downstream device.

Substep S1052: and acquiring the related upgrading information of the local downstream equipment through the registration command of the local downstream equipment.

The local downstream device may register with an upstream device directly connected to the local downstream device, for example: when the local downstream device is a leaf device, the local downstream device can directly register with the local; for another example: the equipment sequentially connected with the local area is equipment 1, equipment 2 and equipment 3 respectively, the equipment 3 registers to the equipment 2, the equipment 2 registers to the equipment 1, and the equipment 1 registers to the local area; when the device 2 registers with the device 1, the registration command may carry the related upgrade information of the device 3 together, and similarly, when the device 1 registers locally, the registration command may carry the related upgrade information of the device 3 and the device 2 together.

The local downstream device may also register with an upstream device indirectly connected to the local downstream device, for example: and registering the upstream equipment indirectly connected with the local downstream equipment, if the upstream equipment is not local, sending no response message, directly continuing to forward the upstream equipment until the upstream equipment forwards the response message to the local, feeding back the response message by the local, informing the downstream equipment that the registration command has been received in the local, and obtaining the related upgrading information of the downstream equipment.

The local downstream device may also register with upstream devices that are directly and indirectly connected to the local downstream device. For example: and registering with the upstream equipment directly connected with the local downstream equipment, and after the registration is successful, registering with the upstream equipment indirectly connected with the local downstream equipment until the response message is forwarded to the local and locally fed back. By the method, each device can obtain the relevant upgrading information of all the downstream devices of the device, and technical support is provided for subsequent purposeful and targeted forwarding.

In an embodiment, the registration command includes a device registration command and/or a transfer registration command, where the device registration command is a registration command sent by the local downstream device performing device registration with an upstream device directly connected to the local downstream device, and the transfer registration command is a registration command sent by the local downstream device performing transfer registration with an upstream device directly connected to the local downstream device and an upstream device indirectly connected to the local downstream device.

In an embodiment, before the step of obtaining the registration command of the local downstream device in sub-step S1051, the method may further include: and controlling the local downstream equipment to send the equipment registration command to upstream equipment directly connected with the local downstream equipment so as to enable the upstream equipment directly connected with the local downstream equipment to acquire the related upgrading information of the local downstream equipment.

Specifically, the process of device registration may be: generating a registration data packet with a predetermined format; controlling the local downstream device to send the registration data packet to an upstream device directly connected with the local downstream device; and controlling the upstream equipment directly connected with the local downstream equipment to receive 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 comprises: controlling the local downstream device to send the device registration command to an upstream device directly connected to the local downstream device at a predetermined time interval.

By the mode, the new upgrading requirement that the upgrading scheme needs to maintain the expansibility and can cope with equipment plugging and unplugging at any time can be met.

In another embodiment, before the step of obtaining the registration command of the local downstream device in sub-step S1051, the method may further include: and controlling the local downstream equipment to send a transmission registration command to the upstream equipment directly connected with the local downstream equipment and the upstream equipment indirectly connected with the local downstream equipment so as to enable each equipment in the local downstream equipment to acquire relevant upgrade information of all the local downstream equipment. And controlling the local downstream equipment to send a transmission registration command to the upstream equipment directly connected with the local downstream equipment and the upstream equipment indirectly connected with the local downstream equipment at preset time intervals.

In a specific embodiment, the controlling the local downstream device to send a transfer registration command to an upstream device directly connected to the local downstream device and an upstream device indirectly connected to the local downstream device may further include: and after the device registration is successful, controlling the local downstream device to send a transmission registration command to the upstream device directly connected with the local downstream device and the upstream device indirectly connected with the local downstream device.

Specifically, the procedure of transferring the registration may be: generating a registration data packet with a predetermined format; controlling the local downstream equipment to send the registration data packet to the upstream equipment directly connected with the local downstream equipment and the upstream equipment indirectly connected with the local downstream equipment until the registration data packet is sent to the local equipment; and controlling the local to return a response data packet to the downstream equipment directly connected with the local.

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

Wherein the command identification code comprises a device registration command identification code or a transmission registration command identification code.

In an embodiment, step S102 may specifically include: and downloading an upgrade package of a version corresponding to the target equipment according to the detected upgrade triggering operation of the user and the current version information of the target equipment. For example, after a user selects target equipment to be upgraded, and a list needing upgrading is formed, upgrading is triggered by one key, and an upgrading package of a version corresponding to the target equipment is downloaded according to detected upgrading triggering operation of the user and current version information of the target equipment.

In an embodiment, before step S103, the method may further include: sending a prepare to transmit command to the target device. And the local pre-stores the related upgrading information of the local downstream equipment and the connection relation between the local downstream equipment. The content of the command to be transmitted comprises identity information of the equipment, whether the equipment is upgraded or not and whether the downstream equipment of the equipment is upgraded or not. In this way, on one hand, the device can be prepared for upgrading, and on the other hand, the local downstream device can transmit the upgrading packet of the version corresponding to the target device in a targeted and purposeful manner.

For example: as shown in fig. 3, the current downstream devices connected to the local are 4, and the current downstream devices are, from near to far, device a (directly connected to the local), device B (directly connected to device a), device C (directly connected to device a), and device D (directly connected to device B); the contents of the ready-to-transmit command are: equipment A, upgrading equipment A (namely equipment A is target equipment), and upgrading downstream equipment of the equipment A; the equipment B is not upgraded, and the downstream equipment of the equipment B is upgraded; the equipment C is upgraded (namely the equipment C is target equipment), and downstream equipment of the equipment C does not exist; device D, device D upgrade (i.e., device D is the target device), and device D's downstream devices do not. When the upgrade package of the version corresponding to the target device is transmitted to the device a, the device a acquires the upgrade package of the version corresponding to the device a due to the upgrade of the device a, and then forwards the upgrade package of the version corresponding to the target device to the device B, C directly connected to the device a; after the device B receives the information, the device B directly forwards a device D connected with the device B because the device B is not upgraded but the downstream device of the device B is upgraded; after the device C receives the update packet, the device C obtains the update packet of the version corresponding to the device C and does not forward the update packet because the device C is updated and has no downstream device (that is, the device C is a leaf device); after the device D receives the upgrade request, the device D has no downstream device due to the upgrade of the device D, and the device D obtains the upgrade package of the version corresponding to the device D and does not forward the upgrade package.

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

At this time, the method may further include: and receiving the upgrading progress pushed by the downstream equipment directly connected with the local equipment until the target equipment is upgraded.

In most cases, the number of the target devices is two or more, and details of step S103 will be described in detail below.

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

Substep S1031: and transmitting the upgrade packages of the versions corresponding to more than two target devices and the identity information of the target devices in parallel to the downstream device directly connected with the local device.

Sub-step S1032: and controlling downstream equipment directly connected with the local device to execute matching operation according to the identity information of the target device so as to enable the target device to obtain the upgrade package of the corresponding version, wherein each device in the local downstream equipment stores the identity information of the downstream equipment.

When the number of the target equipment is more than two, the target equipment is transmitted to the downstream equipment directly connected with the local area in parallel, so that the condition that the upgrading time is excessively prolonged due to the fact that the number of the upgrading equipment is large in sequential transmission can be avoided, and the new upgrading requirement of large number of the upgrading equipment can be met.

The target device to be upgraded can be classified into the following cases: the first kind of target device includes target leaf devices (the target device does not need to forward after receiving the upgrade package of the corresponding version), the second kind of target device includes target intermediate devices (the target device determines whether to forward according to whether the downstream device needs to be upgraded after receiving the upgrade package of the corresponding version), and the third kind of target device includes target leaf devices and target intermediate devices, which can be implemented by combining the first and second kinds of situations.

The target device comprises a target leaf device, and can be divided into two cases: the first type of target device is a downstream device directly connected to the local device (the target device directly receives the local upgrade package corresponding to the version), and the second type of target device is a downstream device indirectly connected to the local device (the target device can receive the upgrade package corresponding to the version only if an intermediate device between the target device and the local device is transferred to the target device).

The target device includes a target intermediate device, and can be divided into four cases: the first is that the target device is a downstream device directly connected to the local device, the downstream device of the target device does not need to be upgraded (the target device directly receives the upgrade package of the local corresponding version, and the target device does not need to be transferred), the second is that the target device is a downstream device directly connected to the local device, the downstream device of the target device needs to be upgraded (the target device directly receives the upgrade package of the local corresponding version, and the target device needs to be transferred to the downstream device), the third is that the target device is a downstream device indirectly connected to the local device, the downstream device of the target device does not need to be upgraded (the target device needs to be transferred to the target device in the middle between the target device and the local device, and the target device can receive the upgrade package of the corresponding version, and the fourth is a downstream device indirectly connected to the local device, The downstream device of the target device needs to be upgraded (the target device can receive the upgrade package of the corresponding version only if the target device needs to be transferred to the target device by the intermediate device between the target device and the local, and the target device needs to continue to transfer to the downstream device).

The concrete description is as follows:

The method of the embodiment of the present application is described in detail below by taking a remote controller and an unmanned aerial vehicle system as examples.

Referring to fig. 4, fig. 4 is a schematic view of an application process of the device upgrading method in the application in the remote controller and the unmanned aerial vehicle system, and the method includes the following steps:

1. the device pushes a heartbeat package (including related upgrading information of the device) to a local APP in a registration mode, the devices of the unmanned aerial vehicle are locally organized, an upgrading management list is formed in the local APP, and the content of the upgrading management list can include whether each device needs to be upgraded (determined according to the current version information of the device and the upgradable latest version corresponding to the device) and the upgradable latest version corresponding to the device, and the upgradable latest version is notified to a user;

2. the local APP does not need to pay attention to the connection state of each device, and updates the upgrade management list only according to the existence of heartbeat package pushing of each device;

3. the user can select the equipment needing to be upgraded to form a list needing to be upgraded and trigger the upgrading by one key;

4. after receiving an operation of triggering upgrading by a user, the local APP downloads an upgrading package of a version corresponding to target equipment in a list according to the list needing upgrading of the user;

5. after downloading is finished, the local APP sends a transmission preparation command to the target devices in the list to be upgraded in parallel and transmits upgrade packages to the target devices in parallel without sequentially transmitting and upgrading;

6. after the upgrade package transmission of the versions corresponding to all target devices to be upgraded is completed, the local APP sends an upgrade trigger command to the downstream devices (also referred to as direct downstream devices) directly connected with the local APP, the direct downstream devices respectively trigger the target devices in the list to be upgraded to perform internal upgrade, and the local APP receives the upgrade progress pushed by the direct downstream devices until all the target devices are upgraded.

In the step 1, the devices perform heartbeat packet pushing in a registered mode, so that multiple devices can be organized, and a foundation is laid for solving the new requirements of upgrading the devices, namely that the number of upgraded devices is large, the upgrading scheme needs to keep expansibility, and the devices can be plugged and unplugged at any time. A typical upgrade scenario of a consumer-grade unmanned aerial vehicle is shown in fig. 5, a typical upgrade scenario of an industrial-grade unmanned aerial vehicle is shown in fig. 2, upgrade topological graphs of the consumer-grade unmanned aerial vehicle and the industrial-grade unmanned aerial vehicle both have a tree structure, and the upgrade topological graphs are collectively referred to as an equipment tree in the embodiment of the application. The local APP is a root node of the equipment tree; each device is a tree node; a device without downstream devices downward is a leaf device (leaf node); the device having the downstream device downstream is an intermediate device (intermediate node). For a typical device tree for a consumer drone (see fig. 5), the remote control is an intermediary device and the airplane is a leaf device. For a typical equipment tree of an industrial-grade unmanned aerial vehicle (as shown in fig. 2), a remote controller and an airplane are intermediate equipment, and peripherals and mounts are leaf equipment.

In order to convert a physical device tree into a logically processable device tree, the embodiments of the present application use "device registration" and "transport registration". The device registration may be: the downstream device registers with the directly connected upstream device (direct upstream device) to let each device node know the existence of its own directly connected downstream device (direct downstream device); the transfer registration may be: after the device registration is successful, the downstream device registers with the directly connected upstream device (direct upstream device) and the 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 pushed by the downstream device to the upstream device in the form of heartbeat packets, i.e., at a frequency of 1 Hz. If a heartbeat packet for registration of certain downstream equipment is received for the first time, the equipment is added into a local APP upgrading management list; if the heartbeat packet of a certain downstream device is overtime, that is, the local APP has not received the heartbeat packet for registration of the downstream device within a certain time (for example, the specific implementation time may be 5 seconds), the local APP considers that the device is not in a connected state, and the local APP removes the device from the upgrade management list. Therefore, the way of pushing the heartbeat packet for registration enables the local APP to be free from concerning the connection state of each device, and can realize the expansibility of the upgrading scheme and deal with the random plugging and unplugging of the devices.

In addition, the content included in the local APP upgrade management list may be: device type, device ID, status of whether the device needs to be upgraded, latest version of the device on the server. The state of whether the equipment needs to be upgraded is that the current version of the equipment is compared with the latest version on the server, if the current version of the equipment is smaller, the equipment needs to be upgraded, otherwise, the equipment does not need to be upgraded.

In this embodiment, please refer to fig. 6 for specific implementation of device registration: after the downstream device C is connected with the upstream device B, C needs to send a registration data packet with a specified format and uploads the registration data packet to the upstream device B; and after receiving the registration data packet, the upstream equipment B sends back the registration data packet with the same format and sends the registration data packet to the downstream equipment C. After this process is completed, it is regarded that the device registration of the downstream device C to the upstream device B is successful. The data format of the registration command can be seen in table 1.

Table 1 registration command data format

Data content	Remarks for note
		Command id	Device registration command id, or transport registration command id
Device name	Name, character string of the device
		Device id	Id of the device itself
Type of device	Type of the device, enumerated value
		Communication id	In this device registration, the upstream device id

In this embodiment, please refer to fig. 6 for specific implementation of transmission registration, after the downstream device C successfully registers with the upstream device B, the downstream device C sends a registration packet with a specified format to the upstream device B (the registration command id is distinguished from the registration command id registered by the device); after receiving the response data packet, the upstream device B only feeds back the response data packet to the downstream device C; meanwhile, the upstream device B forwards the registration data packet of the downstream device C to the root node A; and after receiving the response data packet, the root node A only feeds back the response data packet to the equipment B. After this process is finished, it is regarded that the transmission registration of the downstream device C to the direct upstream device and the indirect upstream device is successful.

In step 2, the upgrade management list of the local APP is updated according to the heartbeat packet pushed for registration. In step 3, the user can select the target device to be upgraded to form a list to be upgraded, and the upgrade is triggered by one key. It should be noted here that the user selects the target device of the upgrade from the upgrade management list of the local APP, and if the device is the latest version, the gray color is displayed on the interface, and the user cannot select the target device. And after a list needing to be upgraded is formed, clicking one key by a user to upgrade. And in the step 4, downloading the upgrade package of the version corresponding to the target equipment in the list to be upgraded.

And in the step 5, the local APP transmits the upgrade package corresponding to the target equipment in the list needing to be upgraded in parallel. In the existing upgrading scheme of consumption-level unmanned aerial vehicle APP, APPs are upgraded equipment one by one and are sequentially transmitted and upgraded, and according to the scheme of the embodiment of the application, local APPs transmit a transmission preparation command to target equipment in a list needing to be upgraded in parallel, and then an upgrading package of the target equipment is transmitted. If the list to be upgraded comprises a plurality of target devices, the processes are parallel. In this embodiment, referring to fig. 7 to 11, a specific implementation of sending a ready-to-transmit command may be that, for an industrial-grade drone, a common upgrade scenario may include: scene one, a local APP independently upgrades one device; scene two, local APP upgrading all devices; scene three, local APP upgrades one leaf device in all devices; scene four, local APP upgrades one intermediate device in all devices; and a fifth scenario, upgrading a certain group of equipment in all the equipment by the local APP. The local APP, as the root node of the device tree, sends the ready-to-transmit command down. The command to be transmitted in this embodiment is different from the command to be transmitted in the APP upgrade scheme of the consumer-grade drone, and two more flag parameters are required, and the command format of the command to be transmitted in this embodiment may be shown in table 2.

In a third scenario, a local APP upgrades one leaf device of all devices (as shown in fig. 9, a target device to be upgraded includes an E device, the E device is a leaf device indirectly connected to the local, an intermediate device is included between the E device and the local, and the intermediate device is a B device and a C device, respectively), and values of commands to be transmitted may be referred to in table 5.

Device id	Flag1 whether the device itself is upgraded or not	Flag2 for upgrading downstream equipment of equipment

After the transmission preparation command is successfully sent, the local APP transmits an upgrade package to target equipment needing 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 links of the local APP and each target device to be upgraded are different, the transmission modes may also be different, which is not described herein. And after the transmission of all the upgrade packages is successfully finished, performing the step 6: the local APP sends an upgrading triggering command to the direct downstream equipment, the direct downstream equipment can respectively trigger target equipment in a list needing upgrading to carry out internal upgrading, and the local APP receives the upgrading progress pushed by the direct downstream equipment until the upgrading is finished.

According to the method and the device for updating the device tree, the target device to be updated is made to be a node of the device tree through a device registration and transmission registration mode, and the local APP is a root node of the device tree. When a device (whether a peripheral on a remote controller or a mounted device on an airplane) is plugged, the local APP adds the device into an upgrade management list according to a heartbeat package for registration of the device; if the device 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 the devices accessed into the device tree in the embodiment of the application meet the implementation and data standard of registration, the local APP can realize the upgrade of the devices, can conveniently process the plugging and unplugging of the devices, and meanwhile keeps the expansibility of the upgrade scheme. After the user triggers the upgrade, the local APP sends an upgrade instruction to the target devices of the device tree in parallel and transmits upgrade packages to the target devices in parallel according to a list to be upgraded, and after the transmission of the upgrade packages of all the target devices to be upgraded is completed, the local APP triggers the internal upgrade of the target devices at the same time. Therefore, a user can upgrade by one key only by selecting target equipment needing to be upgraded, and meanwhile, the parallel transmission replaces the sequential transmission upgrading in the existing scheme, so that the upgrading time under the condition of multiple equipment can be greatly reduced.

In summary, through the scheme of the embodiment of the application, the local APP can well meet the new requirement of upgrading that "upgrading equipment is large in quantity, keeps expansibility, can deal with equipment plug at any time", thereby achieving the upgrading target of the industrial unmanned aerial vehicle: the user can select the target equipment needing to be upgraded from the multiple equipment to carry out one-key upgrading.
