Description

Technical Field

[0001] The present invention relates to the field of fault self-checking of smart home control, and more specifically, to a fault self-checking method and system for smart home control. Background Art

[0002] With the rapid development of my country's economy and technology, smart home devices have entered all aspects of our lives. However, with the development of automation and intelligence of home appliances, the frequent failures of smart home control systems, the difficulty in troubleshooting the causes of failures, and the low automation rate of troubleshooting have become a big problem on the road to the development of intelligent equipment control. The existing intelligent control system fault self-checking method mostly uses a centralized controller to send call data to the fault line. The intermediate device or terminal device in the fault line receives the call data and then feeds back the response data. The centralized controller analyzes the feedback response data to determine the cause of the fault of the fault line. This detection method uses the fault line as a monitoring loop. When a physical connection failure occurs at a node or multiple nodes of the fault line, only the fault node closest to the centralized controller in the fault line can be detected, and the subsequent fault nodes cannot be monitored and checked. As a result, after the fault point is repaired, the fault still cannot be completely solved, which greatly increases the detection time and detection cost. At the same time, this detection method can usually only complete the troubleshooting of communication data failures, but cannot accurately and quickly complete the specific node location of physical failures. Therefore, how to realize the automated and rapid detection and troubleshooting of smart home device control system faults is an urgent problem to be solved in the entire smart home device control system industry. Summary of the invention

[0003] In view of this situation, we propose a fault self-detection method and system for smart home control to solve the above problems.

By analyzing the attenuation of the physical level signal and the communication program data packet communication data loss rate, the target line fault point and the cause of the fault are finally determined.
