The Control System Of Multi-Variable Environment Simulate Hermetic Cabin

Many environments that people can depend on and exist could be solved by manmade environment, but manmade environment should be affected by adjustment characteristic of system, it will produce certain fluctuation; this fluctuation can influence the physiological function of the people, even it can create the serious harm. Therefore developing the environment simulation hermetic cabin that the stress, temperature, humidity, oxygen, carbon dioxide, vibration and noise etc can be adjusted, research many kinds of synthetically influences of multi-variable environment to the physiology function of animal such as single variable and the stress, temperature, humidity, oxygen, vibration and noise etc and its harm, looks for out the regularity of its influence to reach and probably gives rise to the critical scope of damage to the human body physiology function, and then but the measure of environment variable which sought actively to prevent and control inside the hermetic cabin looks has the meaning very much.This paper is a part of scientific research item "coupling of sound and cement bond logging of shipping hermetic cabin and the influence of multi-variable environment simulative hermetic cabin to body". It mainly studied the measurement and control system of the simulative hermetic cabin to realize the adjustment of temperature, humidity, stress, oxygen, carbon dioxide, vibration and noise etc. And the parts of system design to the hermetic cabin and corresponding have carried on the technology explanation. In addition, it introduced the processing and demarcation of sensor of concerned measurement data and the curve to draw up to close and software that the multi-variable environment simulation hermetic cabin is controlled the course to realize.This paper mainly studied measurement and control system of the multi-variable environment simulative hermetic cabin. It specific introduced the basic component of the multi-variable environment simulative hermetic cabin and the work principle of measurement and control system. How Expounded testing and controlling seven variables such as temperature, humidity, stress, oxygen, carbon dioxide, vibration and noise etc.It is different from single variable environment simulate hermeticcabin before, this paper expounded the basic component of multi-variable environment simulation hermetic cabin and the work principle of measurement and control system to develop of it, it advanced the method of the preset checkout and the jointly control of multi-variable such as temperature, humidity, stress, oxygen, carbon dioxide, vibration and noise etc, it has been designed to realize computer measurement and control of environment simulate hermetic cabin.
