Description
Technical field
The present invention relates to data communication field, especially a kind of method, terminal and server for transmitting lora message.
Background technique
Lora (long range) is one kind of low-power consumption wide area network (LPWAN), and Lora network is disposed mainly by end
End, gateway, Loraserver server and cloud collectively form, it can be achieved that using data transmitted in both directions.Yun He
The communication mode of Loraserver server is capable of supporting several protocols, including MQTT (Message Queuing Telemetry
Transport, message queue telemetering transmission), HTTP (HyperText Transfer Protocol hypertext transfer protocol)
Deng, it is required according to the difference of business, it is also different using the length of data, such as Transmission Control Protocol, it is dealt into from application server
The message length maximum possible of LoraServer server is 1500 bytes.And Lora communication is most extensively being covered using minimum speed limit
Once most multipotency carries 250 bits when the speed grade 0 of lid.Using lora encoded bandwidth 125Khz, in flank speed class 5
When, it can once carry 11000 bits.
It is also gradually multiple to the business demand of uplink and downlink as Lora technology is widely used in various application environments
It is miscellaneous, apart from remote Lora terminal since environmental restrictions have to be transmitted using the low rate of DR0, needed for a business packet
When the byte number wanted is more than 250 bits, if not only head needs use to fall a large amount of byte using existing IP fragmentation technology
Number, and be simple cheap single-chip microcontroller since lora terminal is generally, the fragment of existing IP agreement complexity cannot be supported well
Technology.
Current existing scheme is application server end using existing agreement (such as IP agreement) progress fragment, is needed simultaneously
It wants terminal also to support the agreement, and fragment and recombination can be carried out to the message for being more than length.But due to this method nor lora
Consensus standard cannot be compatible between different business so the realization of terminal is different, need each application server end according to
Lora ability carries out distinctive fragment size design for Lora transmission, or even needs to consider used by current Lora terminal not
Same rate is changed fragment size, this not only increases the complexity at application server end, also increases Lora and industry
The coupling of business code.Obviously it is less applicable in.
