The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprise," "have," and any variations thereof, are intended to cover non-exclusive inclusions, such that a process, method, system, article, or ZigBee device that comprises a list of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, article, or ZigBee device.
The embodiment of the application can be used in the environment of the ZigBee device shown in fig. 1, and includes: the system comprises a cloud server (1001), a mobile terminal APP (1002), a ZigBee gateway (1003) and ZigBee devices (1004, 1005 and 1006). And the ZigBee equipment and the ZigBee gateway perform data interaction through a ZigBee protocol. The ZigBee gateway and the cloud server can be connected through the Internet to perform data interaction. The mobile terminal APP is used for reminding a user whether to upgrade or not for the APP used on the user mobile phone or other ZigBee equipment, and then data interaction between the cloud server and the ZigBee gateway is triggered. It can be understood that the number relationship shown in this figure is only an illustration, and in an actual use process, a plurality of ZigBee devices may be interconnected with a ZigBee gateway, or a plurality of ZigBee gateways may be interconnected with a cloud server, and the specific details are not limited herein.
Referring to fig. 2, an embodiment of a ZigBee device upgrading method according to the present application includes: step 201-step 203.
201. The server acquires the target version firmware and the current version firmware.
The method comprises the steps that a server obtains a target version firmware and a current version firmware, wherein the current version firmware is a firmware currently used by ZigBee equipment, the target version firmware is obtained by upgrading the current version firmware, the server needs to obtain the current version firmware currently operated by the ZigBee equipment for upgrading the ZigBee equipment, specifically, the server can inquire upgrading records of the ZigBee equipment to obtain the firmware currently used by the ZigBee equipment, and can also perform data interaction with a ZigBee gateway mutually connected with the ZigBee equipment to inquire to obtain the firmware currently used by the ZigBee equipment. Meanwhile, a target version firmware is required to be obtained, the target version firmware is obtained by upgrading a current version firmware used by the ZigBee device, and certain difference or optimization exists compared with the current version firmware so as to adapt to the current use condition. It can be understood that the ZigBee device can normally operate both in the case of using the target version firmware and in the case of using the current version firmware. The server may be a server provided locally, or may be a cloud server formed by a plurality of servers, and is not limited herein.
202. And the server operates a differential algorithm according to the target version firmware and the current version firmware to obtain differential firmware.
And the server operates a differential algorithm according to the target version firmware and the current version firmware to obtain differential firmware. The difference firmware is obtained by comparing the target version firmware and the current version firmware by the server according to a difference algorithm, and mainly comprises difference files between the target version firmware and the current version firmware, and information such as the corresponding relation of storage addresses of the difference files. The differential upgrading firmware and the current version firmware can be restored through a differential algorithm to obtain the target version firmware. At present, the upgrading method generally adopted by the ZigBee device which adopts the ZigBee standard protocol for communication is an OTA full upgrading method of the ZigBee standard protocol, namely, the complete target version firmware is sent to the ZigBee device through the ZigBee standard protocol, and the ZigBee device uses the complete target version firmware to replace the currently operated version firmware to complete upgrading. The mode of using differential package is different from the mode of full upgrade in the 'starting point'. The full upgrade can be directly carried out without an old version upgrade package, so that the full upgrade can be applied to ZigBee devices of all versions, and the differential upgrade package is used between two determined versions. The size of the differential upgrade package may vary greatly due to differences between versions, but is generally much smaller than the entire package, while the size of the full upgrade package is determined by the entire package, and the amount of data is generally large. The use of simultaneous differential packetization has a large limitation and cannot be applied to all versions as full-size packets. Therefore, the differential packet is usually required to be detected and verified when in use so as to ensure the normal operation of the upgraded ZigBee device. The upgrade security of the differential upgrade package is high.
203. And the server sends the differential firmware to the ZigBee gateway.
And the server sends the differential firmware to a ZigBee gateway so that the ZigBee gateway sends the differential firmware to the ZigBee device according to a ZigBee protocol and finishes upgrading. The ZigBee gateway is a coordinator node or a router node in the ZigBee network, has the functions of being responsible for building, maintaining and managing the network, is responsible for forwarding data packets, and relays communication between terminal ZigBee equipment and a server. The work performed by a specific server can refer to the process of generating and transmitting differential firmware to the ZigBee gateway, which mainly includes 3. And after receiving the differential firmware, the ZigBee gateway sends the differential firmware to the ZigBee device according to the ZigBee protocol, so that the ZigBee device finishes the upgrading process according to the differential firmware.
Referring to fig. 4, an embodiment of a ZigBee device upgrading method according to the present application includes: step 401-step 402.
401. The ZigBee gateway receives the differential firmware.
The ZigBee gateway receives differential firmware, the differential firmware is obtained by a server according to a target version firmware and a current version firmware through running a differential algorithm, the current version firmware is a firmware currently used by the ZigBee device, and the target version firmware is obtained by upgrading the current version firmware.
The ZigBee gateway has the capability of receiving data sent by the server, and can perform data interaction with the ZigBee device through the ZigBee protocol at the same time, as described in the corresponding embodiment of fig. 2. Meanwhile, in order to ensure that the ZigBee device is normally upgraded, the ZigBee gateway can verify the differential firmware to determine the validity of the differential firmware, and then determine whether the differential firmware is accepted, if the version of the differential firmware cannot be applied to upgrading of the ZigBee device connected with the ZigBee gateway, the ZigBee gateway can also return corresponding error information to the server, and the specific details are not limited herein.
402. And the ZigBee gateway sends the differential firmware to the ZigBee device according to a ZigBee protocol.
And the ZigBee gateway sends the differential firmware to the ZigBee device according to a ZigBee protocol so that the ZigBee device can be upgraded according to the differential firmware. The ZigBee gateway sends the differential firmware to the ZigBee device after receiving the differential firmware, and the sending process of the differential firmware follows the ZigBee protocol, and the method specifically comprises the following steps:
(1) the ZigBee gateway sends specific information of the differential firmware to the ZigBee device, so that the ZigBee device determines whether to be upgraded according to the differential firmware.
(2) And the ZigBee device sends a data request to the ZigBee gateway, wherein the data request comprises the size of the data block which can be received by the ZigBee device.
(3) And the ZigBee gateway decomposes the differential firmware into data blocks with the size acceptable by the ZigBee device according to the data request information, and sends one data block to the differential firmware.
(4) And after receiving the data block, the ZigBee device sends a data request to the ZigBee gateway again to obtain the next data block.
(5) And the ZigBee gateway sends the next data block. And repeating the steps (3) and (4) for multiple times until the differential firmware transmission is completed.
The data transmission process of the ZigBee protocol is completed, and since the data transmission process follows the ZigBee protocol, those skilled in the art can easily know the specific transmission process, the detailed description is omitted here. Meanwhile, it can be understood that the data requested by the ZigBee device may also be a data page including a plurality of data blocks, thereby reducing the number of data request requests sent by the ZigBee device.
Because the difference upgrading packet is smaller than the full upgrading packet, under the condition that the data amount required by the ZigBee device every time is not changed, the data requiring request times required to be sent by the ZigBee device are less, and the power consumption of the ZigBee device in the upgrading process is reduced.
According to the technical scheme, the embodiment of the application has the following advantages: the method comprises the steps of differentiating a new version firmware file to be transmitted and a current version file operated by ZigBee equipment to obtain a differential upgrade package, and transmitting the differential upgrade package to the ZigBee equipment according to a ZigBee protocol, so that the ZigBee equipment can complete upgrading only by asking for the differential upgrade package, and the volume of the differential upgrade package is smaller than that of the complete new version firmware file, so that the frequency of asking for data from a ZigBee gateway by the ZigBee equipment is reduced in the transmission process of the differential upgrade package, the power consumption of the ZigBee equipment in the transmission process is reduced, and the practicability of the ZigBee equipment is improved.

The steps 701 and 702 are similar to the steps 201 and 202 in the corresponding embodiment of fig. 2, and are not described in detail here, it is to be noted that, since the ZigBee device is an embedded device, the differential algorithm used should be adjusted accordingly to ensure that the obtained differential firmware can be normally used on the ZigBee device.
703. The server compresses the differential firmware.
The server compresses the differential firmware. After the upgraded firmware is obtained, the server compresses the firmware to further reduce the volume of a firmware package, and further reduces the data volume required to be transmitted when the ZigBee gateway interacts with the ZigBee device. The data request times required to be sent in the upgrading process of the ZigBee equipment are reduced, and the implementation of the scheme is improved.
704. The server judges whether an upgrading triggering instruction exists or not.
After obtaining the differential firmware available for upgrading, the server may interact with the user to determine whether to perform data transmission to perform an upgrading process, for example, to send version upgrading information to a mobile phone or an APP used by the user, so that the user determines whether to need upgrading according to the version upgrading information, and if the user sends an upgrading trigger instruction to the server, it indicates that the user has an upgrading requirement, and the data should be sent to the ZigBee device.
705. The server divides the differential firmware into a plurality of data blocks.
In the actual use process, the situation that the storage capacity of the ZigBee gateway is poor and the complete differential firmware cannot be stored possibly exists, so that the differential firmware can be divided into a plurality of data blocks to adapt to the storage capacity of the ZigBee gateway, and the divided data blocks are sent to the ZigBee gateway, so that the ZigBee gateway sends the data blocks to the ZigBee device in batches, and then upgrading is completed.
706. The server sends a plurality of data blocks to the ZigBee gateway
And the server sends the divided data blocks to the ZigBee gateway, so that the ZigBee gateway stores the received data blocks and sends the data blocks to the ZigBee device.
707. And the ZigBee gateway sends the differential firmware to the ZigBee device according to the ZigBee protocol.
After the ZigBee gateway receives the differential firmware, the differential firmware information can be sent to the ZigBee device, so that the ZigBee device can verify the differential firmware, and if the differential firmware is verified correctly, the ZigBee device sends a data acquisition request to the ZigBee gateway, and then triggers the sending process of the ZigBee gateway to the differential firmware. The ZigBee gateway can also execute a verification process of the differential firmware, and the differential firmware is sent to the ZigBee device after verification is completed. The specific process is similar to step 402 in the embodiment corresponding to fig. 4, and is not described here again. It should be noted that, when the data stored in the ZigBee gateway is some data blocks constituting the differential firmware, after the ZigBee gateway completes sending the stored data blocks, the server needs to delete the sent data blocks, and then obtain other data blocks again and send the data blocks until the differential firmware is completely sent. The specific data sending form of the ZigBee gateway to the ZigBee device may be sent in a data page form, or in a data block form, and is specifically determined according to the model of the ZigBee device, it can be understood that the ZigBee gateway may send the differential firmware to a plurality of ZigBee devices according to a ZigBee protocol, and due to the property of the ZigBee network, one ZigBee gateway may have a plurality of ZigBee devices having a data interaction relationship with the ZigBee gateway, and therefore, in the sending process, the ZigBee gateway may send the differential firmware to each ZigBee device one by one, or may send the differential firmware to a plurality of ZigBee devices at the same time, and is specifically determined according to an actual situation, and the present disclosure is not limited herein.
708. And the ZigBee device decompresses the differential firmware.
Since the differential firmware is compressed differential firmware, before the differential firmware is used, the differential firmware needs to be decompressed to obtain decompressed differential firmware, so that the differential firmware is convenient to use, a decompression algorithm used in a decompression process corresponds to an algorithm used when the compressed differential firmware is generated by a server, and meanwhile, the decompression algorithm can be written into the ZigBee device in advance when the ZigBee device leaves a factory, or can be sent to the ZigBee device by the ZigBee gateway after the ZigBee device establishes network connection with a network manager, and the specific details are not limited herein.
709. The ZigBee device runs a differential algorithm according to the current version firmware and the differential firmware to obtain the target version firmware.
The ZigBee device runs a differential algorithm according to the current version firmware and the differential firmware to obtain the target version firmware. The target firmware is the firmware to which the ZigBee device needs to be upgraded, and this step is similar to step 502 in the implementation corresponding to fig. 5, and is not described here in detail.
710. And the ZigBee equipment is upgraded according to the target version firmware.
And the ZigBee equipment is upgraded according to the target version firmware. After the ZigBee device obtains the target version firmware, the ZigBee device can verify the target version firmware and judge whether the differential algorithm is correctly executed to verify whether the firmware can be normally used. And if the verification is successful, upgrading according to the target version firmware. The specific upgrading mode comprises the following steps:
(1) and the ZigBee device replaces the current version firmware with the target version firmware. The ZigBee device can copy the target version firmware and cover the target version firmware over the current version firmware, so that the firmware used by the ZigBee device is replaced by the target version firmware to complete upgrading.
(2) And the ZigBee device modifies the firmware operating address, and modifies the firmware operating address originally pointing to the firmware of the current version into the storage address of the firmware of the current target version in the ZigBee device, so that the operating firmware in a use state is the firmware of the target version, and the upgrading process is completed.
