A system and method for real-time acquisition and communication of signal data

Abstract

The invention discloses a real-time acquisition and communication system of signal data, which includes a master node and several slave nodes wirelessly communicating with the master node, the master node includes a master node Bluetooth module and a master node LoRa module, and the slave node includes a slave node LoRa module and the slave node Bluetooth module, the master node Bluetooth module issues an open command, the slave node Bluetooth module receives the open command, opens the slave node LoRa module and writes to the LoRa channel at the same time; the master node Bluetooth module issues a close command, and the slave node Bluetooth module receives Turn off the command to close the LoRa module of the slave node; when the LoRa module of the master node and the LoRa module of the slave node are turned on, the master node follows the communication protocol of the master-slave node and sends an instruction with the authentication code protocol format to the LoRa module of the slave node, and the LoRa module Deal with it accordingly. The invention does not need to care about the communication between acquisition devices, and only needs to transfer data according to the interface protocol standard during development, which effectively improves the convenience of use and ensures the stability, controllability and flexibility of communication.

Description

technical field [0001] The invention relates to the field of information collection and communication, in particular to a system and method for real-time collection and communication of signal data. Background technique [0002] At present, the business scenario of collecting real-time data from various sensors through terminal equipment in an offline state is mainly realized by short-distance data collection through Bluetooth or wireless transmission through LoRa, which is a low-power wide-area network. Facing the long-distance and low-power communication requirements of the Internet of Things, the technical characteristics of low-power wide-area networks include: long transmission distance, generally exceeding 2.5km; low power consumption of nodes, which can be used for a long time in the Internet of Things scene; simple network structure , low operation and maintenance costs. [0003] The existing implementation methods mainly have the following disadvantages: Bluetooth ...
