This is a design based on the library temperature and humidity automatic measurement system and control system. Using modern information gathering techniques, computer data processing and control technology, through the choice of hardware devices and designing of software programs, it is feasible to achieve automatic detection of the library temperature and humidity parameters and control of air conditioning equipment. Demonstrated by engineering examples, the system structure is clear, stable and reliable. It has significantly improved the quality of preservation of books in the library, therefore, has a wide prospect in the field of library temperature and humidity control.

And Control

A temperature and humidity control system of storehouse environment is proposed in this paper, and the hardware structure and Software function are designed based on virtual instrument technology. The design of hardware system includes two parts, one is to monitor temperature and humidity, the other is to control them through turning on/off the executive device. The systematic software was divided into two major function modules: monitor and control module and data management module. In order to reduce the influence of interference and ensure the system stability, the anti-interference program is designed in the system software. Testing result shows the control system is feasible and effective for improving the precision of storehouse environment control.

Embedded Implementation

For the characteristics and needs of temperature and humidity control in current industrial environment, the paper proposes a fuzzy-based embedded temperature and humidity control system，which enables consumers monitor and control temperature and humidity parameters through the PDA when moving. The article first introduces the hardware structure of the temperature and humidity fuzzy control system, then based on the theory of fuzzy set and the fuzzy number operations of l - cut set, focusing on the transition rules of fuzzy controlling fuzzy conditions of the temperature and humidity control systems, and finally introduce the key technologies of embedded software system of the PDA,. The experimental results show that the system is very practical and flexible.

And Control

The structure and principle of four-wheels independent driving and steering (4WIS-4WID) electric vehicle are presented firstly, and on this basis the structure of network control system base on CAN bus is built. Kinematics and dynamics models of typical steering modes (such as all wheel steering, front (rear) wheel steering, parallel steering, zero-radius steering) are built, and the control strategy is presented. The experimental results show that the control system structure and control algorithm are effective.
