Abstract

The invention relates to a sensor configuration redundancy determination method and system based on energy balance, and the method is characterized in that the method comprises the following steps: 1)constructing an energy network model of a networked system; 2) establishing a measurement equation of the energy network model according to the input and output energy balance of the nodes in the energy network model and the configuration mode of the sensors in the networked system; and 3) determining the measurement redundancy of the networked system in the sensor configuration mode according tothe non-zero row number and rank of the measurement equation coefficient matrix in the measurement equation of the energy network model. The method can be widely applied to the technical field of networked system measurement.

Description

technical field [0001] The invention relates to a method and system for determining redundancy of sensor configuration based on energy balance, and belongs to the technical field of networked system measurement. Background technique [0002] How to obtain the state of the measured object with fewer sensors has always been an important and basic problem in the field of sensor measurement. The correlation between networked systems makes certain redundant information exist between sensors, which can be used to correct the measurement data acquired by sensors or estimate unknown measurement quantities. The redundant information between sensors is a measure of One of the important indicators of different sensor configuration schemes. Therefore, it is particularly important to quantify the information redundancy of different sensor configuration schemes. [0003] Some methods in the prior art start from the description of the structure of the system under test, and select the sm...
