基于Lora技术的远程报警装置

Remote Alarm Device Based on LORA TechnologyAbstractWith the development of society,the city is more and more prosperous,and thereare more and more roads.At the same time,there are some safety problems in roadconstruction.In order to ensure the safety of construction personnel on the road,this topicis designed to solve the safety problems.This project is a remote alarm device based onLora technology.The whole system is composed of STC89C51,Lora communicationmodule,mpu6050 acceleration sensor,LCD,buzzer,etc.The device has good induction,simple circuit and can alarm in various environments.When the device detects theabnormality through the acceleration sensor,the microcontroller will send information tothe alarm receiving device through Lora wireless to remind,and alarm through the buzzer.It can also display the relevant information through the LCD,so as to achieve the effectof real-time alarm in case of safety condition during road construction.Altium designer isused in the design of schematic diagram.In this paper,in addition to the schematic design,C language programming,but also through the Proteus simulation software for simulationverification of related functions,to achieve the design goal,and has high practicability.Key Words:MCU;Lora;Mpu6050;Alarm
