| Abstract: | This paper presents the architecture of a type HC-STD86 microcomputer and the structure of hardware and software of the process control system for a vertical kiln in a cement works. An 8 bit data line has been extended to a 16 bit one with the bus stealing technique in the microcomputer. It conforms to STD-BUS industrial standard. However, its processing speed is 1.5 times that of 8088 CPU. A two level microcomputer control system is composed of HC-STD86 and IBM-PC. The control cycle is 1 sec with 6 control loops; the A/D processing accuracy is less than 0.5%; the operation and display accuracy is less than 0.1%. |
