Moreover , reliability index is analyzed comparatively of the single , dual and triple microcomputer regulator . The dual microcomputer reliability is not further more changed , because of the unduly complex automatic switchover model . It is suggested that the major study of improving the microcomputerbased governor reliability trend to the simplified architecture and the optimized systematic function . Single microcomputerbased governor application study is the instance with the high reliability. The system function formulation , microcomputer core hardware selection , along with manmachine interface allocation are the main aspects to improve the microcomputerbased governor reliability. It has not only actual application value to numerous middle and small type governors , but also has the refer
