A Wireless Measurement And Control System Based On μC/OS-Ⅱ

With the development of computer and communication technology, computer meaturement and control system is becoming more and more complicated. Microprocessors in industrial scenes often operate sevral tasks including data acquisition, data transmission, equipment control at the same time. In this case, it is very necessary to transplant an embedded operating system at microprocessors.This paper selects uC/OS-II to transplant. On the basis of understanding, paper cuts the core volume to serval hundred bits, and transplants it at SPCE061A single-chip computer. There is no example on transplantion at SPCE061A, so the paper writes procedures to implement the transplantion. Test proves that it is successful to transplant. The paper creats two tasks to implement asynchronous serial communication. Transplanting μC/OS-Ⅱ at microprocessors in the industrial scene improves the real-time character and dependability. Embedded real-time operating system is beneficial to more complicated problem too.This paper studies a wireless meatruement and control system based on SPCE061A. The system is composed of 6179 industrial computer, SPCE061A one-chip computer and radio modem modules. Among them, One-chip computers gather data and receive the commands from host-computer. Industrial computer works as control centre. The paper selects Visual C++ to programme procedure and uses MSComm to realize serial communication. Radio modem modules connect the two parts. The achievements of this paper have important practical and realistic significance.
