Real-time acquisition and communication system and method of signal data

Abstract

The invention discloses a real-time acquisition and communication system of signal data. The system comprises a master node and a plurality of slave nodes in wireless communication with the master node, wherein the master node comprises a master node Bluetooth module and a master node LoRa module, each slave node comprises a slave node LoRa module and a slave node Bluetooth module, the master nodeBluetooth module issues an opening/closing instruction, and each slave node Bluetooth module receives the instruction, opens/closes the slave node LoRa module, and simultaneously writes to a LoRa channel; when the master node LoRa module and the slave node LoRa modules are in an opened state, the master node follows a master-slave node communication protocol and sends an instruction with an authentication code protocol format to the slave node LoRa modules, and the LoRa modules carry out corresponding processing. According to the scheme of the invention, the communication between acquisitiondevices does not need to be concerned, data can only be transferred according to the interface protocol standard during development, the convenience of use can be effectively improved, and the stability, controllability and flexibility of communication can be ensured.

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 ...
