Description

technical field [0001] The invention relates to the technical field of loop monitoring, in particular to an Internet of Things data access and preprocessing system for loop monitoring and an installation method thereof. Background technique [0002] With the development and popularization of intelligent industry, the probability of failure of electrical equipment in the industry has increased significantly. Therefore, when the electrical equipment fails, it is necessary to identify the faulty electrical equipment through the loop monitoring system in time, and quickly shut down the branch where the faulty electrical equipment is located through the control system to reduce the loss caused by the fault. The loop monitoring system is used for low-voltage distribution networks. In the system, it is used to monitor the real-time voltage of the three-phase four-wire or single-phase loop, and the monitored data needs to be read, processed, and the system's command transmission and...

AI Technical Summary

Problems solved by technology

However, the structure and installation method of the data access and preprocessing system in the prior art are complicated, and the loop monitoring data and the operating data of the concentrator need to be processed by different systems, and the loop monitoring data and the operating data of the concentrator cannot be uniformly processed. The communication method is single, and the data access and preprocessing system needs to be disconnected when connecting with other devices, so it is not possible to perform safe installation without power failure
