Abstract


Measurement of human understanding of the world and thus an important means of transforming the world , the sensor is to measure the direct experience of the system being measured information of the device, hope that it will be useful according to certain rules of the output signal . However, due to performance factors effect sensor itself , the sensor output is nonlinear . And in most cases , due to electromagnetic waves, noise, and the external environment , the sensor becomes more complicated nonlinear . Sensing system for non-linear and interference correction factors simultaneously , which for sensor technology development and improvement of the performance measurement system has important theoretical significance and practical value. Modern measurement system based on the input - output relationship generally linear , and by temperature measurement , the effect of noise and other factors , this non-linearity becomes more complex , the use of conventional methods to establish a comprehensive calibration of mathematical models is difficult . The neural network has a good fault tolerance and associative memory function, a strong adaptive ability , and has strong nonlinear mapping ability , highly nonlinear approximation problem is easy to solve . Therefore, the use of neural networks to establish the characteristics of the corresponding detection system model and error correction model is an ideal choice. In this issue of the study, the neural network theory into the measurement system, the establishment of non-linear calibration model integrated measurement system to improve system accuracy. This function approximation using a strong ability to learn using BP algorithm multilayer feedforward network that BP neural network to build an integrated linear measuring system calibration model , and using fast BP algorithm to train the network , through simulation, to obtain the effective measurement system neural network model . Working mainly reflected in: 1 wide temperature range, pressure effects diacetone density modeling ; 2 under the action of pressure and temperature diacetone velocity measurement neural network modeling ; 3 . Hydrochloric acid concentration ultrasonic non-intrusive sensing systems Forward and reverse modeling .
