A method and device for relay protection of civil buildings based on the Internet of Things

Abstract

The invention discloses a civil building relay protection method based on the Internet of Things, and a dual-channel operation mode is designed, and the dual-channel can be installed locally or in different places according to actual needs, and they are mutually backed up to improve the reliability and reliability of the device. Fault tolerance. The functions of the two complement each other and serve as backups for each other. The local channel provides the on-site stable execution function in the offline state, and the remote channel provides more convenient remote monitoring, control and recovery functions when the communication status is normal. The present invention can transmit signals to other management terminals through mobile Internet communication, local area network, Internet, etc. through the Internet of Things communication module, provides a remote control and remote analysis capability, and improves the efficiency of daily maintenance and early warning of failures.

Description

technical field [0001] The invention relates to the field of instrument manufacturing and control, in particular to a relay protection method and device for a civil building based on the Internet of Things. Background technique [0002] In civil buildings, the use of relay protection devices is very large, and failures are inevitable, and the abnormal operation of devices or accidents are likely to cause economic losses and even casualties. Therefore, the operating status of the relay protection device and the efficiency of post-accident processing are very important. However, in civil buildings, the common situation is that the professional and technical personnel are unable to arrive in time, the lack of spare parts, and the difficulty in troubleshooting the fault point, etc., which lead to excessively long troubleshooting time, higher costs, and even larger failures. [0003] The characteristics and problems of conventional relay protection devices mainly include: [00...

AI Technical Summary

Problems solved by technology

[0004] (1) Have certain automation capabilities, but often only have mechanized action processes, cannot intelligently analyze various fault types, and are prone to malfunctions, difficulties in troubleshooting after faults, etc.;

[0005] (2) A 16-bit DAC chip digital signal processor is generally used, and the operation processing speed is limited, which cannot meet the increasing control accuracy requirements;

[0006] (3) Generally, a single machine operates independently. If the device itself fails, it will cause the failure of the protected line, resulting in immeasurable economic losses;

[0007] (4) It generally has an interface to connect to a computer, but generally only provides a wired interface, which cannot meet the requirements of the Internet of Things for communication interface methods and communication networking methods;

[0008] (5) Generally, on-site operation is required, which increases the workload of maintenance personnel and is not conducive to early warning of daily failures;

[0009] (6) Generally, limited output contacts are provided, which is not conducive to function expansion
