With experimental method, the efferts of the surface process technology of hard counterpart on the operating performances of sealing systems are studied and revealed.

For analysing of the way of practical application of ATT7022B in ARM in detail,the identity and principle of energy chip ATT7022B are introduced,and combining with the applications of protection devices in the mine for the parameters collection,the design of LPC2292 and ATT7022B hardware interface and software programming are given.

According to the demand of the development of a configuration software for electric system monitoring and control,the hardware interface based on OPC specification for data communication between PC applications and SIMENTIC S7300 PLC is presented, including its general architecture and the implementation of different functions.

The author proposes an opening hardware interface model and illustrates the way of implementation.

Based on analysis on hardware connection and program design, the article probes into the experimental device in which microprocessors laboratorial instruments and LED lattice screen are well combined, and optimizes the equipment that enhances students microprocessors application skill.

This thesis comes from the project of the connecting hardware test in lab in Asian-Pacific R&D center of Tyco Electronics Shanghai Raychem Cable Accessory Ltd.
