LoRa .Retaining wall and stone management system using LoRa network system.

摘要

The present invention is an automatic measurement management system used to monitor the maintenance and collapse risk signs of a retaining wall or masonry, a plurality of measuring units 100 installed on the retaining wall or masonry to detect vibration and movement; and the measuring unit It includes; central server 200 for storing and managing the data calculated from, but the measuring unit collects the amount of deformation caused by vibration and movement from the origin, and transmits the collected amount of deformation to the central server 200; , In the above, each measurement unit 100 has a unique ID; a gps sensor that calculates a coordinate value for a current position with respect to the origin of the x-axis, y-axis, and z-axis coordinates and transmits it to the data transmission/reception unit (110); and the data transmission and reception unit 120 for transmitting the coordinate value received through the gps sensor to the central server with a unique id; By including the deformation data can be collected accurately, utilizing the Lora network system By delivering the collected data to a central server, however, LoRa can improve the data transmission speed by not going through an intermediate node terminal (repeater), and can quickly capture the signs of collapse of the retaining walls and stone shafts at low cost and low power.
