Linear series type online monitoring system and troubleshooting method thereof

Abstract

The application provides a linear series type online monitoring system and a troubleshooting method thereof; when receiving a global self-checking instruction transmitted by a superior device, an i-th sensor device feeds back a self-checking state return instruction to the superior device, simultaneously forwards the global self-checking instruction to a subordinate device, and when receiving a self-checking state return instruction from the subordinate device, feeds back a self-checking feedback success state instruction to the subordinate device; when the i-th sensor device does not receive any one of the global self-checking instruction, the self-checking state return instruction and the self-checking feedback success state instruction within a global self-checking time period, the i-th sensor device preliminarily identifies a suspected fault device. The global self-checking instruction is issued within the global self-checking time period, the suspected fault device in the online monitoring system is preliminarily identified, and thus it is convenient for a worker to troubleshoot.
