This paper describes the makeup and working principle of MAX691A supervisor circuits, and its application to the anti-interference and power-fail protection circuit of the 80c196kc single-chip micro controller system is presentedalso, as well as the hard ware connection circuit and the corresponding software design method .
There are many kinds of interruptions coming from power source,which influence the stahility of single chip computer application system,According to the analysis on soris of operation of industry locate power source,this paper has introduced anti-interruption circuit by using power source supervision circuits TL775A, this paper also introduced another antiinterruption and power-fail protection circuits by using μp supervision circuits MAX 693.By using these two kinds of circuits,The application system can eliminate the interruptions coming from power source.
This system has many functions such as communicating with the automatic programming sy-stem,voltage frequency regulation carried and by software,power failure protection,and so on,therefore itca eliminate the defects of all kinds of xiating controller.
This paper deals with the electric furnace intelligent control systems of MCS- 8098. Thecontrol circuit consists of on-line test of thermocouple and output signal,power failure protection andbreakdown report. It discusses the method of intelligent controller self-test and self-diagnosis. Thepaper studies the PID based on the expert system for the SK-Ⅱ electric furnace.
Introduce the principle of the multi-user water meter based on the single chip microprocessor and the schematic circuit of the detection and measurement of water Introduce the way of the power failure protection of the memory
Analysis is made on its speed metering, depth metering, pulse counter display, setting (automatic) input velocity, setting alarm velocity, setting coding factors and power-off protection and the characters of auto/manual operation.
