[0002] In large-scale intelligent farming scenarios, many controllers or sensors based on Long Range Wide Area Network (LoRaWAN) communication are usually deployed to monitor the farming environment, farming equipment, and farmed animals in real time. Due to the differences in monitoring needs in different seasons and regions, these LoRaWAN-based devices are often upgraded using remote over the air (OTA) to meet new monitoring needs.

[0050] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0051] It should be understood that the terms "include" and "comprising" used in the specification and claims of the present disclosure indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections thereof.

[0052] It should also be understood that the terms used in this disclosure are only for the purpose of describing specific embodiments and are not intended to limit the disclosure. As used in this disclosure and claims, the singular forms of "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise. It should also be further understood that the term "and / or" used in this disclosure and claims refers to any combination of one or more of the associated listed items and all possible combinations, including these combinations.

[0053] As used in this specification and claims, the term "if" may be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" may be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0054] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0055] Reference Figure 1 , Figure 1The flowchart of the method for remote upgrading of the device in the embodiment of the present disclosure is shown, which is applied to the control end. Figure 1 The method 100 for remote upgrading of a device shown in the figure is applied to a control end, and the control end includes a cloud platform, a server and a LoRaWAN gateway, including: at step S101, using the cloud platform, responding to the upgrade operation instruction to send an upgrade query request to the server. In some embodiments, the control end includes a cloud platform and a server, and a LoRaWAN gateway of the transmission layer. In the breeding scenario, the cloud platform can be a breeding cloud platform, which not only supports remote upgrading of the device end in the breeding farm, but also provides functions including data management, monitoring system, intelligent analysis and connection with breeding equipment. The server corresponds to the cloud platform, and the cloud platform can flow various data in the cloud, while the server is used to process various data and requests, and also supports data storage and management. The LoRaWAN gateway is used to connect the LoRa device on the device end with the server. It can not only receive data sent from the LoRa node through wireless transmission and forward it to the server, but also send data and information sent by the server to the device end.

[0056] When the device side needs to be upgraded, the user can trigger the upgrade operation instruction through the small program of the mobile terminal or the short web page of the PC, and the upgrade operation instruction will be published to the cloud platform through Ethernet based on the message queue telemetry transmission protocol (Message QueuingTelemetry Transport, MQTT). The cloud platform responds to the upgrade operation instruction, generates an upgrade query request and sends the upgrade query request to the server through Ethernet and MQTT protocol. The upgrade query request also includes the total number of upgrade packages, which will be transmitted to the device side by the LoRaWAN gateway later to inquire whether the device side starts the device upgrade. In a feasible implementation, the present disclosure divides the remote upgrade of the device into a unicast upgrade type and a multicast upgrade type. Unicast upgrade can be understood as the mode corresponding to the upgrade of a single sub-device. Multicast upgrade can be understood as the mode corresponding to the upgrade of batch sub-devices. When sending an upgrade query request, the upgrade type can be determined according to the upgrade operation instruction previously triggered by the user. If it is a unicast upgrade type, an upgrade query request is sent to the server through the cloud platform. If it is a multicast upgrade type, an upgrade query request is sent to the server based on a preset time interval and a preset number of times through the cloud platform. Optionally, as a feasible implementation, the preset time interval can be set to 3 seconds, and the preset number of times can be set to 3 times. When sending, the cloud platform will send an upgrade inquiry request to the server once every three seconds until it is sent three times in a row.

[0057] It should be noted that when the cloud platform responds to the upgrade operation instruction, it will also create an upgrade record. The upgrade record is used to record the upgrade information related to each link, including the upgrade time, upgrade progress, etc. If the upgrade fails, the record can help to roll back and restore the device to the state before the upgrade. By writing the details of the device upgrade into the upgrade record, it is convenient for subsequent query and management. When any of the following trigger conditions is met, the cloud platform will modify the upgrade record accordingly. The trigger conditions are: the cloud platform receives the confirmation upgrade information transmitted by the target device or the missing package resend request; the cloud platform sends the upgrade package to the server to complete.

[0058] Next, at step S102, the server and the LoRaWAN gateway are used to transmit the upgrade query request to the device end. In some embodiments, when the server obtains the upgrade query request, it will transmit it to the LoRaWAN gateway by wireless transmission. The LoRaWAN gateway will also send the request to the sub-devices (i.e., the device end) managed by itself by wireless transmission. Since the transmission method of the LoRaWAN gateway can reach a transmission distance of several kilometers and cover a wider communication area, it is more suitable for remote upgrades of LoRa devices in large-scale breeding scenarios compared to the Bluetooth upgrade method.

[0059] Further, at step S103, the cloud platform, server and LoRaWAN gateway are used to respond to the confirmation upgrade information sent back by the target device to transmit the upgrade package to the target device. In some embodiments, after the device side receives the upgrade inquiry request, the device that needs to start the upgrade (hereinafter referred to as the target device) will send a confirmation upgrade message to the control side. The cloud platform of the control side can confirm whether the device side starts the upgrade now through the confirmation upgrade information. After that, for the target device, the cloud platform will transmit the previously split upgrade package and the target device identification and other data to the server together. The server further sends the upgrade package and other data to the specified LoRaWAN gateway according to the connection topic of the remote upgrade. Finally, the LoRaWAN gateway sends the upgrade package and other data to the specific sub-device (ie, the target device) according to the target device identification. The target device verifies the upgrade package after receiving the upgrade package, and performs the upgrade operation based on the upgrade package after the verification is correct. It is understandable that the control end uses the cloud platform, server and LoRaWAN gateway to send upgrade packages and other data to the device end, thus overcoming the defect that long-distance wide area network devices can only be upgraded remotely over short distances via Bluetooth, making it more suitable for large-scale breeding scenarios.

[0060] In addition, it should be noted that the cloud platform will modify the upgrade record accordingly when receiving the upgrade confirmation information sent by the control end and when the upgrade package is sent down, so as to update the upgrade progress, such as upgrading in progress or upgrade completed.

[0061] Reference Figure 2 , Figure 2 A flowchart of a method for remotely upgrading a device to which another embodiment of the present disclosure can be applied is shown. Figure 2 The method 200 for remote device upgrade shown in the figure includes: at step S210, using the cloud platform, responding to the upgrade operation instruction to send an upgrade query request to the server. At step S220, using the server and the LoRaWAN gateway to transmit the upgrade query request to the device end. At step S230, using the cloud platform, the server and the LoRaWAN gateway, responding to the confirmation upgrade information sent back by the target device to transmit the upgrade package to the target device. In some embodiments, step S230 also includes: at step S231, using the cloud platform, determining the device identification of the target device according to the confirmation upgrade information. In some embodiments, the confirmation upgrade information sent back by the target device contains the identification of the device itself, and the device identification corresponds to the target device one by one, and can uniquely identify the target device, which can be a device ID or a MAC address, etc. Taking the device ID as an example, the cloud platform parses the confirmation upgrade information sent back by the target device to determine the device ID of the target device.

[0062] Then, at step S232, the cloud platform is used to send the split upgrade package and the corresponding JOSN file to the server in order. In some embodiments, the cloud platform will previously split the upgrade package into multiple files, and generate a CRC (cyclic redundancy check) check code for each split file, which is used to subsequently verify the data integrity of the split files. In addition, the cloud platform will also generate a corresponding JSON file to record the name, order, corresponding CRC check code and target device ID of each file. Subsequently, the cloud platform packages the split upgrade package files and the corresponding JSON together, and uses the MQTT transmission protocol to send the packaged files to the server in order. It should be noted that the upgrade package split by the platform is a difference package generated by differential compression based on the pre-update version and the updated version. The difference package only contains the difference data between the versions. When updating, only the changed part needs to be processed, which improves the upgrade efficiency and reduces bandwidth usage.

[0063] In addition, when the device is in networking, working, standby and other states, it will upload gateway configuration data, business data, keep-alive messages and other content to the control end. After receiving this data, the cloud platform will determine the data type and transfer the data to the cloud according to different data types. For example, if it is business data, it will be transferred to the corresponding business system; if it is keep-alive information, the correspondence between the device and the corresponding gateway is determined based on the keep-alive information and saved by the server; if it is gateway configuration data, the corresponding gateway configuration rules are saved through the server; if it is firmware upgrade completion information, the upgrade status of the corresponding device is updated according to the firmware upgrade completion information. Optionally, the cloud platform can choose Alibaba Cloud Platform for deployment.

[0064] Subsequently, at step S233, the server is used to determine the gateway identifier according to the JOSN file, and the upgrade package and the JOSN file are sent to the corresponding LoRaWAN gateway based on the gateway identifier. In some embodiments, the server previously stores the networking correspondence between the sub-device and the LoRaWAN gateway to which it belongs. The server searches for the corresponding relationship stored in itself through the target device id in the JOSN file, thereby finding the gateway identifier of the LoRaWAN gateway to which the target device belongs. The gateway identifier can uniquely identify the gateway, which can be a gateway id or other identifier that can uniquely represent the gateway. Then, the server sends the received upgrade package file and the JOSN file to the corresponding LoRaWAN gateway according to the gateway identifier.

[0065] Finally, at step S234, the LoRaWAN gateway is used to determine the device identification according to the JOSN file, and the upgrade package and the JOSN file are sent to the corresponding target device in sequence based on the device identification. In some embodiments, when the LoRaWAN gateway receives the upgrade package and other content sent by the server, it can parse the JOSN file to determine the device identification (such as the device ID), and then forward the upgrade package and the JOSN file to the target device in sequence according to the device identification.

[0066] It should be noted that in the multicast upgrade mode, in addition to sending the upgrade query request based on the preset time interval and the preset number of times, the cloud platform also needs to perform the splitting and sending of the upgrade package based on the preset time interval and the preset number of times, that is, after each preset time interval, step S231-step S234 is performed once until the preset number of times is reached. Correspondingly, the cloud platform will also modify the upgrade record after each upgrade package is sent.

[0067] It is understandable that step S210 and step S220 can be combined with the above Figure 1 The described steps S101 and S102 are the same or similar and will not be described again here.

[0068] Reference Figure 3 , Figure 3 A flowchart of a method for remotely upgrading a device according to another embodiment of the present disclosure is shown. Figure 3 The method 300 for remote upgrading of the device shown, after step S103, further includes: at step S310, using the cloud platform, receiving and responding to the missing packet retransmission request sent by the target device, so as to execute the step of using the cloud platform, server and LoRaWAN gateway to respond to the confirmation information sent back by the target device and transmit the upgrade package to the target device. In some embodiments, after receiving the upgrade package sent after splitting, the target device will verify it. If it is verified that there is a missing packet, a missing packet retransmission request will be sent to the control end. After receiving the missing packet retransmission request, the cloud platform will retransmit the upgrade package, that is, the steps of using the cloud platform, server and LoRaWAN gateway to respond to the confirmation information sent back by the target device and transmit the upgrade package to the target device are executed again. By retransmitting the upgrade package when the target device fails to receive the upgrade package, it can be ensured that the target device finally obtains a complete and correct upgrade package, so that the target device completes the firmware update, and the flexibility of remote upgrading of the device end is improved.

[0069] Then, at step S320, when the heartbeat packet transmitted by the target device is received, the cloud platform is used to verify the version number to determine whether the target device has been successfully upgraded. In some embodiments, after the target device is upgraded based on the upgrade package, it uploads a heartbeat packet to the control end, and the heartbeat contains the device id and the current version number. The cloud platform receives the heartbeat packet sent back by the target device and parses the content. Next, the cloud platform compares the received version number with the version number of the preset target version. If they match, the platform records that the upgrade is successful, and also updates the device status in the upgrade record; if they do not match, the corresponding retry or fault handling procedure may be started. In this embodiment, by verifying the version number of the heartbeat packet, the device status can be monitored in real time, and devices that have not been successfully upgraded can be discovered in time, reducing the troubleshooting time and improving the efficiency of fault handling.

[0070] Reference Figure 4 , Figure 4 The method flow of remote device upgrade of the device end using the embodiment of the present disclosure is shown. Figure 4The method 400 for remote upgrading of the device shown includes: at step S410, receiving the upgrade query request sent by the control end, and transmitting confirmation upgrade information back to the control end. In some embodiments, the device end is a single node device under the LoRaWAN gateway. These node devices will upload gateway configuration data, service data, and keep-alive messages to the control end in networking, working, standby and other states. In addition, these node devices can also monitor the communication channel based on the LoRaWAN protocol and receive upgrade query requests from the LoRaWAN gateway. When the upgrade query request is received, the validity and format of the request will be parsed and verified to confirm the content of the request. Afterwards, the target device on the device end will generate confirmation upgrade information, which includes the current firmware version, upgradeable version and other content. Subsequently, the device end will transmit the confirmation upgrade information back to the control end, first back to the LoRaWAN gateway, and then transmitted to the server and cloud platform by the LoRaWAN gateway, so that the cloud platform will eventually perform the subsequent operation of issuing the upgrade package based on the confirmation upgrade information.

[0071] Then, at step S420, the upgrade package sent by the control end is received and it is verified whether the upgrade package is missing. In some embodiments, the control end will start to send the upgrade package after receiving the confirmation upgrade information from the device end. After the device end receives the upgrade package sent by the control end, it will verify whether the received upgrade package is missing. Optionally, in a feasible implementation, the device end can use a CRC verification method. That is, by calculating the CRC verification value of the upgrade package, the calculated CRC value is compared with the CRC value sent by the control end. If they are the same, it is confirmed that the upgrade package is complete. If they are different, it is confirmed that there is a missing package. In this embodiment, the reliability of the upgrade process of the device end can be improved by verifying the upgrade package.

[0072] Further, at step S430, if the upgrade package is not missing, the upgrade package is spliced ​​to obtain a complete upgrade package. In some embodiments, when the device side verifies that there is no missing package in the upgrade package, the upgrade packages are spliced ​​in sequence according to the package order to obtain a complete upgrade package. Optionally, the device side can also perform an integrity check on the complete upgrade package after splicing to ensure that there are no errors in the splicing process. Finally, at step S440, based on the complete upgrade package, an upgrade operation is performed. In some embodiments, after the device side confirms that there is no missing package in the upgrade package and the splicing is completed, the device side can perform an upgrade operation based on the complete upgrade package through its own firmware upgrade process and execute an upgrade command. It can be understood that the device side performs remote upgrades of the device based on the LoRaWAN communication protocol, which overcomes the defect that long-distance wide area network devices can only perform short-range remote upgrades through Bluetooth, and is more suitable for large-scale breeding scenarios.

[0073] Reference Figure 5 , Figure 5Another embodiment of the present disclosure is shown, which is applied to a method flow of remote device upgrade on a device side. Figure 5 The method 500 for remotely upgrading a device shown includes: at step S510, if there is a missing packet in the upgrade package, a missing packet resend request is sent to the control end. In some embodiments, when the control end sends the upgrade package to the device end, it may be affected by network fluctuations, etc., resulting in a missing packet in the upgrade package received by the device end. The device end can detect whether there is a missing packet in the received upgrade package by checking the upgrade package. If there is a missing packet, the device end will send a missing packet resend request to the control end, so that the control end resends the upgrade package so that the device end performs the upgrade operation again when it receives a complete upgrade package.

[0074] And, at step S520, after detecting that the upgrade operation is completed, a heartbeat packet is sent to the control end. In some embodiments, the device end creates a heartbeat packet after the upgrade is completed, which contains information such as device id, version number, current status, timestamp, etc. Subsequently, the device end sends the heartbeat packet to the LoRaWAN gateway of the control end based on the LoRaWAN communication protocol. The control end can not only update the connection status between the device and the control end according to the received heartbeat packet, but also verify whether the upgrade of the device end is successful according to the version number, thereby improving the reliability of the remote upgrade of the device end based on the LoRaWAN communication protocol.

[0075] In order to facilitate the understanding of the technical solution disclosed in this disclosure, the following are respectively combined Figure 6 and Figure 7 To explain the interaction process between the control end and the device end. Figure 6 , Figure 6This is the interaction process between the control end and the device end in unicast upgrade mode. The control end includes the cloud platform, server and LoRaWAN gateway. When the upgrade operation instruction is triggered, the cloud platform of the control end responds, creates an upgrade record and records the start of the upgrade. At the same time, the cloud platform sends an upgrade query request to the server, which is sent to the LoRaWAN gateway, and the LoRaWAN gateway sends it to the device end. After receiving the upgrade query request, the target device confirms the upgrade and then sends the upgrade confirmation information to the control end. Then, the cloud platform of the control end receives the upgrade confirmation information, modifies the upgrade record accordingly, and then starts to send the previously split upgrade package and the corresponding JOSN file to the server in sequence, which includes the CRC check code, package sequence and target device id. After the sending is completed, the cloud platform modifies the upgrade record. Then, after receiving it, the server determines the corresponding LoRaWAN gateway and sends it to the gateway. After receiving the upgrade package and JOSN file, the LoRaWAN gateway sends it to the corresponding target device again according to the device id in it. After receiving the upgrade package, the target device checks whether there is a missing package. If there is no missing package, it will perform a package upgrade; if there is a missing package, it will send a missing package resend request to the control end. When the cloud platform receives the missing package resend request, it will resend the upgrade package and modify the upgrade record accordingly. After the target device is upgraded, it will upload a heartbeat package to the control end. The cloud platform on the control end verifies the version number of the heartbeat package to determine whether the unicast upgrade is successful and modify the upgrade record accordingly.

[0076] Next, refer to Figure 7 , Figure 7This is the interactive process between the control end and the device end in the multicast upgrade mode. When the upgrade operation instruction is triggered, the cloud platform of the control end responds, creates an upgrade record and records the start of the upgrade. At the same time, the cloud platform continuously sends multiple upgrade query requests to the server based on the preset time interval and preset number of times, and the request is sent to the device end via the server and the LoRaWAN gateway. After receiving the upgrade query request, the target device confirms the upgrade and sends the upgrade confirmation information to the control end. The cloud platform receives the upgrade confirmation information, modifies the upgrade record, and starts to send the previously split upgrade package and the corresponding JOSN file to the server in sequence based on the preset time interval and preset number of times, which includes CRC check code, package sequence and target device id. After each upgrade package is sent, the cloud platform modifies the upgrade record once. Subsequently, the upgrade package is also sent to the target device via the server and the LoRaWAN gateway. After receiving the upgrade package, the target device verifies whether there is a missing package. If there is no missing package, it will perform a package upgrade; if there is a missing package, it will send a missing package resend request to the control end. When the cloud platform receives the missing package resend request, it will resend the upgrade package and modify the upgrade record accordingly. After the target device is upgraded, it will upload a heartbeat packet to the control end. The cloud platform of the control end verifies the version number of the heartbeat packet to determine whether the upgrade is successful and modify the upgrade record accordingly.
