Application Of Integrated Intelligence Control In Environmental Environment-Testing Cabinet System

The thesis introduced based on the DSP56311 digital signal processor integrated intelligence control strategy in the Environment-Testing Cabinet system design and the realization. This control system has used the entire digitized temperature, the humidity intelligence examination and the control plan, not only has realized the system wide scope survey, the high accuracy control, the redundant reliability, meanwhile uses LCD to demonstrate and to touch the screen input, has established the good man-machine contact surface. This article designed using the ADT70 chip had taken the temperature examination electric circuit, and pressed -the frequency transformation chip through AD650 to transform the voltage signal into the frequency code, using HS1101 took the humidity examination electric circuit, transformed the relative humidity as the frequency code, the final process photoelectricity isolation component, transported for the DSP56311 digital signal processor, thus has realized the entire digitized examination. The paper take the environmental testing box temperature, the humidity control sound of something astir condition response as a goal, uses in advance a step of control strategy to the system, optimizes the fuzzy nerve network using the improvement auto-adapted genetic algorithms, Elman recognizes the network the power value. The simulation experiment indicated that, carries on the neural network parameter based on the improvement auto-adapted genetic algorithms to seek superiorly is feasible, effective, the genetic algorithms, the fuzzy control, the neural network three unions have formed the integrated intelligence control, not only enhanced the Environment-Testing Cabinet system to move, the static quality, at the same time strengthened the system robustness. Finally, the screen using the liquid crystal display to realize the environment test run programmable, caused the man-machine contact surface to be friendlier. The paper elaborated the hardware main circuit, the control circuit, the signal examination electric circuit, the liquid crystal display monitor connection electric circuit, touches the screen connection electric circuit and so on the design, has produced the system movement flow chart.
