Abstract

The invention provides an LoRa-based data transmission terminal and a communication system with the same, the data transmission terminal comprises at least two equipment connection interfaces, whereineach equipment connection interface is used for connecting equipment with data processing and communication functions; an LoRa module which is used for transmitting the data of the equipment to the outside or transmitting the data received from the outside to the equipment; a mode selection unit which is used for controlling the selection of the communication mode of the data transmission terminal and the mode selection of the LoRa module; And a processor which is respectively connected with the at least two equipment connection interfaces, the LoRa module and the mode selection unit, whereinthe processor is used for carrying out data forwarding between the LoRa module and the equipment and adding a preamble required by the LoRa module for carrying out data communication. According to the technical scheme, the technical problems that in the prior art, a data transmission terminal is high in power consumption, low in cost-to-efficiency ratio and small in coverage area, and rapid switching between different serial interfaces cannot be rapidly achieved are solved.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a LoRa-based data transmission terminal and a communication system having the same. Background technique [0002] The proportion of today's Internet of Things technology in industry applications is increasing year by year, and it has penetrated into manufacturing, transportation and logistics, health care, consumer electronics, retail, automotive and other application industries. The era of the Internet of Everything is entering our lives at an extremely rapid pace. According to different transmission rates, IoT services can be divided into high-rate services, medium-rate services and low-rate services. [0003] In traditional wide-area connection applications, data transmission is mainly carried out with the help of cellular networks provided by operators. However, there are still a large number of equipment applications that cannot be met by existing cellular netw...
