Description
Technical Field
[0001] The present invention relates to the technical field of 5G infrastructure intelligent detection technology, and in particular to a multi-sensor fusion intelligent detection method and system for 5G infrastructure. Background Art
[0002] In recent years, multi-sensor fusion technology has attracted widespread attention because of its ability to provide more comprehensive and accurate monitoring data. By integrating multiple types of sensors, it can achieve all-round monitoring of 5G infrastructure, timely detect potential problems and take preventive measures.
[0003] A Chinese invention patent with announcement number CN106973086B discloses an intelligent detection system based on multi-sensor fusion, including multiple sensor fusion detection devices, each of which sends data to the cloud via a wireless network. Several sensor fusion detection devices are self-networked through the ZigBee protocol. After networking, the sensor fusion detection device acts as a node to transmit data to a coordinator, and the coordinator transmits the data to a host computer or sends it to the cloud via a wireless network.
[0004] However, the operation of 5G infrastructure faces multiple challenges, the most critical of which is the difficulty in timely detection, diagnosis and handling of equipment failures. Traditional monitoring methods often rely on manual inspections or single sensor data, which is not only inefficient but also prone to missing potential hidden dangers. For example, key information such as equipment appearance damage, temperature and humidity changes, and vibration abnormalities, if not monitored in real time and accurately, will directly affect the judgment of the health status of the equipment. In addition, the incompleteness and availability of data are also important factors that restrict the accuracy of fault detection. In the absence of effective data interaction protocols and processing mechanisms, the collected data may not be effectively integrated and analyzed, thus affecting the accuracy and timeliness of decision-making.
