Abstract With SCM technology， SCM has penetrated into all From household appliances， measuring control instruments， mechanical and electrical integration products to artificial intelligence， aerospace and other fields are large monolithic SCM is a centralized controller integrated circuit chip， memory， computing devices， and input and output ports of the chip micro- It is this feature because it makes the existence of circuits with single chip， can give full play to software and hardware combined with great advantage， maximize savings in hardware resources， to intelligent， multi-functional， making the circuit system developing more SCM powerful， stable performance， it is also high cost， which is widely used in its one of the important In industrial production， scientific research and daily life， the temperature is a measure of the most commonly used The traditional function of temperature measurement complex is limited， especially in the temperature of the display and non-linear processing， there are many Application of microcomputer intelligent temperature measuring instrument manufacturer， has wider range， linearity， convenient and flexible display， you can set the operation of key functions and so Keywords: microcontroller， intelligent， V / F converter， AD
Electronic clock has become a necessity for daily life， It's widely used in the family， stations， terminals， theaters， offices and other places， to people's lives， study， work great The system uses a single chip for the master chip AT89S52， realized the time， date display， modify and time functions， and power-down situation with time to maintain the function of In this paper， AT89S52-based production of single-chip electronic Papers At89s52 chip-based CS-III experiment box， the clock design， the use of the experimental box for 8-bit digital tube， when minutes and seconds and date display， keyboard with me in the time of the modification and alarm clock settings， including school modules， the number of days the month of processing module， a time when every minute modules， output modules and date selection Thus achieve the realization of the electronic
