A factory intelligent inspection system based on lora technology

Abstract

The invention discloses a factory intelligent inspection system based on a LoRa technology, which includes a data acquisition unit, a data transmission unit and an application service unit. The data acquisition unit intermittently acquires device state information, packages the acquired device state information and sends the device state information to the application service unit through the datatransmission unit. The application service unit makes a data analysis of the received device state information, carries out alarm, archiving, analysis and prediction on the analyzed device state information according to rules set in the application service unit in advance, and assists users in making a maintenance decision when the device state is abnormal. The invention aims to reduce the workload of inspection personnel in intelligent factories, avoid error information generated due to man-made factors, improve the quality of inspection, strengthen inspection data management, comprehensively evaluate and predict the overall health state of devices through intelligent inspection, so as to reduce the number of employees and increase efficiency for intelligent factories.

Description

technical field [0001] The invention relates to the technical field of equipment operation status monitoring and the technical field of Internet of Things communication, in particular to a factory intelligent inspection system based on LoRa technology. Background technique [0002] There are many types and huge quantities of factory equipment, and the spatial distribution presents the characteristics of points, lines, and surfaces. In order to ensure the safe, stable and reliable operation of the equipment, it is necessary to conduct regular or irregular inspections on the field equipment. At present, most factories still use the traditional equipment inspection method with handwritten notes as the main feature. It is difficult to accurately grasp whether personnel have arrived at the scene, the inspection is subjective and random, and the inspection quality cannot be effectively guaranteed, resulting in equipment failure usually. With the development of the industry, some...

Problems solved by technology

Although the emergence of the inspection terminal can help to realize the standardization of cement factory equipment inspection to a certain extent, and can accurately and objectively record the work of the inspectors, it is still a human process after all, and it is inevitable that Wrong data, unstable WIFI signal, high power consumption of inspection terminals, easy damage to equipment labels, expensive deployment of intelligent inspection systems, and difficulties in the transformation of existing factory lines have not been well resolved.
