Abstract


The face of the growing complexity of the application environment , vehicle health monitoring system on single sensor can not meet the real-time, fast delivery of high precision and high reliability monitoring and positioning information , as well as a good autonomy to environmental change adaptability , strong anti-interference , as well as the requirements of miniaturization and high cost performance . Good monitoring system for real-time monitoring and alarm through a lot of running status information on the operational status of the key parts of the vehicle operator , which is conducive to a better understanding of the vehicle the vehicle 's performance , and in a timely manner and make the appropriate adjustments to improve the reliability and safety of the vehicle . In this paper, from the better use of the operating status information of the key parts of the vehicle running status in real-time monitoring and alarm , the vehicle health monitoring system based on multi-sensor information fusion technology research as follows : (1) the function chain of neural networks and adaptive mutative scale chaos optimization algorithm combining composition chaos optimization neural network algorithm , and the effect is very obvious nonlinear correction reflect vehicle operating conditions parameter monitoring sensors ; ( 2 ) based on the theory of probability distribution and variable weight analysis , and multi-sensor fusion data validation fuzzy evaluation method has obvious advantages compared with the traditional evaluation method ; (3) to eliminate reflect vehicle operating conditions parameter monitoring sensors in the vehicle during operation by other factors interfere with the effect of the pressure sensor , for example , a two - sensor information fusion , and the results are quite remarkable ;
