In recent years, with the rapid development of science and technology, the application of single chip is accepted broadly in real-time detection and automatic control of microcomputer. Although it’s often act as the core component of single chip system, it is not enough only with the knowledge of single chip. Engineers also need to think about the structure of the hardware to perfect the system.Currently most higher education institutions have built single chip laboratory, equipped with experiment box and other hardware simulation equipment. But the circuitry of the experiment box is fixed and the experiment steps are hard to be changed. It is not fit the trend of rapid development speed of single chip technology. It is also unsuited to develop students’ abilities and creativities. With the introduction of the Proteus software simulation technology, it can be solved at a certain extent. We could design more experiment steps and help students completing their self-study with the simulation experimental platform. It is a positive technology for system construction. Based on the information above, the author design a temperature alarm system with functions of automatic temperature monitoring and artificially infrared temperature adjustment. This system is created based on the single-chip microcomputer simulation environment, using the PIC single chip of MICOCHIP ltd as the main control chip, combined with peripheral infrared sensor, LCD display, temperature sensing, dc motors, heating electric stove wire and alarm equipment. The control system of main chip and main program was written in C program.This design has the advantages of reducing cost and increase practicability. It is could be adopted by most higher education institutions.

Single-chip microcontroller that micro-computer (Single-Chip Microcomputer) gathering CPU, RAM, ROM, the timing, number and variety of interface integrated microcontrollers. Widely used in various fields. In this paper, the music alarm clock designed by AT89S53 SCM control. The music alarm clock from SCM system is the smallest system and the expansion of LED display circuit and voice circuit. Using single-chip C programming language, can be set to achieve a number of alarm clocks, alarm clocks on time to play music, and showing the date and other functions. This paper introduces the music alarm clock software and hardware design, and design, debugging process of the problems encountered and solutions. The topics designed music alarm system is simple, cost, low-cost, multifunctional, with a very strong sense of practicality. Keywords : music, simple arrangements, clock timing 题目:SCM Application Development-music electronic clock design 希望对您有所帮助，祝您成功！
