Description
Technical Field
The invention relates to the technical field of street lamp controller upgrading methods, in particular to a remote upgrading method of a street lamp controller based on NB-IoT.
Background
NB-IoT (Narrow Band Internet of Things) is a cellular system LPWA (Long wavelength evolution) cellular solution introduced by 3GPP (3rd Generation Partnership Project, 3GPP) for supporting ultra-low complexity and low throughput Internet of Things, and has the advantages of low cost, large connection, wide coverage and the like.
The existing upgrading mode of general devices is generally to upgrade through a File Transfer protocol FTP (File Transfer protocol) or a simple File Transfer protocol tftp (triple File Transfer protocol), where FTP is a set of standard protocols used for File Transfer on a network, and works in the seventh layer of the OSI model, the fourth layer of the CP model, i.e. the application layer, uses TCP transmission, and a "three-way handshake" process is required before a client establishes a connection with a server, so that a connection-oriented service is provided. TFTP, however, is also a simple protocol for transferring files, implemented on the basis of the UDP protocol, any transfer starting from a request for reading or writing a file, this request also being a connection request, if the server approves this request, the server opens the connection, the data is transferred in 512 bytes of length, each packet comprises a block of data, the server must get the client's acknowledgement of the last packet before issuing the next packet, and if the size of a packet is less than 512 bytes, this indicates the end of the transfer.
Protocols such as FTP and TFTP appear before NB-IoT, FTP is based on TCP, and due to the characteristics of TCP, it takes time to establish a connection before transferring data, and when transferring data, a lot of time is consumed for acknowledgement, retransmission, congestion, and the like, and connection timeout is easy to occur, which results in failure of upgrade, and is not suitable for NB-IoT, a low-rate network. The TFTP runs on a UDP protocol, but the length is fixed to 512B, the message is too large for an NB-IoT network, and the bandwidth resource occupied by one-time transmission is too long, so that the transmission is easy to fail, and the two protocols are not suitable for the NB-IoT network and do not support breakpoint continuous transmission. The low bandwidth and large delay characteristics of the NB-IoT network are not considered at the beginning of the formulation of the two protocols, the message size cannot be adjusted according to the actual NB-IoT network condition, the upgrading is easy to fail, and after the upgrading fails, the protocols do not support breakpoint continuous transmission and all need to restart the upgrading.

The traditional upgrading modes of FTP, TFTP and the like applied to the IP network do not consider the characteristics of low actual bandwidth and large delay of NB-IoT at the beginning of design, easily cause congestion, occupy too much network bandwidth resources, frequently fail upgrading and the like, and do not have the function of breakpoint transmission. The method can combine the characteristics of low bandwidth and large delay of an NB-IoT network, determine the size of the message required to be upgraded according to the current signal quality, and simultaneously can carry out breakpoint continuous transmission next time when the NB-IoT network is disconnected due to abnormal reasons during upgrading.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
