Design of general object terminals for measure control systems based on embedded platform

摘要

In measure & control related education and training, the specifications such as cost, flexibility, user experience, and the actual operability are impossible combinations for traditional solutions and products of general object (including control object, sensor and actuator, etc.). In order to resolve this problem, a general object terminal was designed, which combined real electrical signal with virtual 3D scene. The mechanical field and other unmanageable fields are transformed to electrical field through mathematical modeling and process channel techniques, which is easier to be controlled. The embedded system provides both electrical signals representing the input and output characteristics of a variety of general objects and 3D interaction to enhance the real experience for users. In the design and implementation of the object terminal, the real time performance, design ability and expansibility are fully considered. Furthermore, combined with the business service software on the server and the standard optional modules, the designed object terminal constructs a novel practical training and evaluation platform which complements virtuality with reality, and combines software with hardware.
