receiving a protocol agreement request sent by the server, and then sending protocol agreement success information to the server, so that the server switches a channel where a product to be upgraded is located according to the content of the protocol agreement after receiving the protocol agreement success information sent by the node, so that the product to be upgraded communicates with the server next time through the switched channel; and after the data command sent by the server is received, writing the upgrading data in the data command into the corresponding storage space of the node and enabling the upgrading data to finish patch upgrading.
5. The patch upgrade method based on the LORA protocol as claimed in claim 4, wherein if the server repeatedly sends a batch of data commands for multiple times, after receiving the data commands issued by the server, writing upgrade data in the data commands into a corresponding space and enabling the upgrade data to complete patch upgrade specifically includes:
after receiving a batch of data commands each time, comparing the received batch of data commands with the data commands existing in the batch of data commands, storing the data commands which do not exist in the batch of data commands, and writing the upgrading data in all the stored data commands into corresponding spaces and enabling the upgrading data after the receiving times reach the preset times so as to finish patch upgrading.
6. The patch upgrade method based on the LORA protocol as claimed in claim 4, wherein after receiving the data command issued by the server, before writing the upgrade data in the data command into the corresponding space and enabling, further comprising:
integrating the upgrading data in the data command according to the upgrading data serial number in the data command, and judging whether the upgrading data is lost or not according to the quantity of the upgrading data in the data command;
and if the upgrade data are not lost, performing security verification on all the upgrade data so as to write the upgrade data in the data command into a corresponding space and enable the upgrade data after the security verification is successful.
7. A patch upgrading device based on LORA protocol is applied to a node, and comprises:
the second verification unit is used for receiving a verification instruction sent by the server, then verifying according to the verification instruction and the version number and the secret key stored by the node according to the second verification unit, and sending verification success information to the server after the version number verification and the secret key verification are both successful, so that the server issues a corresponding data command, wherein the verification instruction comprises the version number to be verified and the secret key to be verified, and different secret keys correspond to different products in the node;
receiving a protocol agreement request sent by the server, and then sending protocol agreement success information to the server, so that the server switches a channel where a product to be upgraded is located according to the content of the protocol agreement after receiving the protocol agreement success information sent by the node, so that the product to be upgraded communicates with the server next time through the switched channel; and the upgrading unit is used for writing the upgrading data in the data command into a corresponding space and enabling the upgrading data after receiving the data command issued by the server so as to finish patch upgrading.
8. A system comprising a server and a node;
the server is used for sending a verification instruction to the node so that the node performs verification according to the version number and the key stored in the node, wherein the verification instruction comprises the version number to be verified and the key to be verified; when the version number verification and the key verification are both successful, the node sends verification success information to the server, and different keys correspond to different products in the node;
after receiving the verification success information sent by the node, sending a protocol agreement request to the node for agreement, and after receiving the protocol agreement success information sent by the node, switching a channel where a product to be upgraded is located according to the content of the agreement so as to carry out next communication with the product to be upgraded in the node through the switched channel; issuing a data command to the node, so that the node writes the upgrading data in the data command into a corresponding space and enables the upgrading data to complete patch upgrading;
the node is used for receiving a verification instruction sent by a server, then verifying according to the verification instruction and the version number and the secret key stored by the node, and sending verification success information to the server after the version number verification and the secret key verification are both successful, so that the server issues a corresponding data command, wherein the verification instruction comprises the version number to be verified and the secret key to be verified;
receiving a protocol agreement request sent by the server, and then sending protocol agreement success information to the server, so that the server switches a channel where a product to be upgraded is located according to the content of the protocol agreement after receiving the protocol agreement success information sent by the node, so that the product to be upgraded communicates with the server next time through the switched channel; and after the data command issued by the server is received, writing the upgrading data in the data command into a corresponding space and enabling the upgrading data to finish patch upgrading.
