Embodiment 1

[0043] refer to figure 1 , the LoRa communication method for improving data downlink efficiency in this embodiment includes:

[0044] S101: When the gateway generates downlink data, put the generated data into different data caches according to the device type corresponding to the downlink data and the real-time requirements of the data;

[0045]The device types include: a first-type device that only receives data, and a second-type device that needs to wait for a reply after going uplink. refer to figure 1 In , we record the first type of equipment as class C equipment, and the second type of equipment as class A equipment.

[0046] In this embodiment, the cache for storing the downlink data corresponding to the class C device is selected as a queue, such as figure 1 The class C queue shown in . The cache used to store the downlink data corresponding to class A devices uses MAP, as shown in the figure, class A downlink MAP.

[0047] The downlink data of class C equipment...

Embodiment 2

[0064] Based on the same inventive concept, this embodiment provides a LoRa gateway, including:

[0065] The downlink data caching module is used to perform data caching according to the device type corresponding to the downlink data and the real-time requirements of the data when the gateway generates downlink data, wherein the device type includes: the first type of device that only receives data, the uplink post A second type of device that needs to wait for a reply;

[0066] The downlink data preparation module is used for, when receiving uplink data from a certain terminal belonging to the second type of equipment, if there is data in the cache corresponding to the certain terminal, then take out the existing data and put it into the sending cache;

[0067] The downlink module is used to take out the data from the cache of the first type of equipment according to the priority order corresponding to the real-time requirements of the data when entering the downlink cycle, a...

Embodiment 3

[0081] This embodiment discloses a LoRa gateway, which is characterized in that it includes a processor and a memory, the memory stores a computer program, and when the computer program is executed by the processor, the steps of the method described in the first embodiment are implemented. For a specific implementation process, reference may be made to the descriptions of the above method embodiments, which will not be repeated here.

Abstract

The invention discloses a LoRa communication method, a LoRa gateway, a LoRa system and a computer readable storage medium. The method comprises the steps: placing the generated data into different data caches according to the equipment type corresponding to the downlink data and the real-time requirements of the data when the gateway generates the downlink data, wherein the device types comprise afirst type of device which only receives data and a second type of device which needs to wait for reply after uplink; when uplink data of a certain terminal belonging to the second type of equipmentis received, if the data exists in the cache corresponding to the terminal, taking out the existing data and putting the existing data into a sending cache; and when entering a downlink period, takingout the data from the cache of the first type of equipment according to the priority sequence corresponding to the data real-time requirement, putting the data into the sending cache until the sending cache is full, taking out the data of the sending cache, and sending the data of the sending cache, thereby ensuring that the sending of the data meets the real-time requirement, reducing the delayof the data, and improving the user experience. The data congestion is prevented, and the network availability and throughput are improved.

Description

technical field [0001] The present invention relates to the field of LoRa communication, in particular to a LoRa communication method, a LoRa gateway, a LoRa system, and a computer-readable storage medium. Background technique [0002] There is no reliable and effective method for downlink data in LoRa applications. Some downlink data with high real-time requirements have high delay, and the utilization rate of the network is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a LoRa communication method, a LoRa gateway, a LoRa system, and a computer-readable storage medium for improving data downlink efficiency in view of the above-mentioned defects of the prior art. [0004] The technical scheme adopted by the present invention to solve its technical problems is: construct a kind of LoRa communication method that improves data downlink efficiency, and described method comprises: [0005] When the gateway...
