Embodiment 1

[0025] The invention discloses a method for monitoring and processing multiple types of sensors, which comprises the following steps:

[0026] Step 1, initialization, to determine the self-test status and number of sensors whose output signals are correlated in the known multi-sensor system, for a multi-sensor system including t sensors with correlated outputs, that is, the output signals are correlated The number of sensors is t. When t is greater than 3, go to step two; when t=3, go to step three; if t=2, go to step four.

[0027] Step 2, when the number of sensors used in the sensor system is t and t>3, first judge whether m sensors have undergone self-inspection, and 0

[0028] If there is no sensor ...

Abstract

The invention belongs to the technical field of industrial monitoring and particularly relates to a method for monitoring and processing various sensors. The method utilizes relativity of signals measured by the various sensors in various sensor systems and adopts multipath measurement signals to achieve failure diagnosis, warning and failure isolation of the sensors, and does not need a single sensor work state monitoring system, thereby simplifying system structure and improving reliability of a self-checking system.

Description

technical field [0001] The invention belongs to the technical field of industrial monitoring, and in particular relates to a monitoring and processing method of multi-type sensors. Background technique [0002] In the field of industrial monitoring, it is usually necessary to use a multi-sensor system to monitor the same measurement object or different measurement objects with correlations synchronously to achieve information complementation and fusion, to expand the application field of sensors, to broaden the measurement range, and to improve measurement accuracy. and robustness. However, the increase in the number of sensors not only increases the complexity of the measurement system, but also increases the failure probability of the system. Therefore, the above factors put forward higher requirements for the fault diagnosis capability of the multi-sensor system itself, so as to ensure the reliability of process monitoring and parameter measurement, and ensure the safe o...
