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.
In recent years, with the rapid development of science and technology, the application of SCM is unceasingly thorough. In real-time detection and automatic control of microcomputer application system, its often as a core component to use. But only the microcontroller knowledge is not enough, should be based on the hardware structure, perfect soft combination.
Most current universities have established the microcontroller laboratory, basically equipped with experiment box and other hardware simulation equipment. But experiment box hardware circuit fixed, experiment content more difficult change, is hard to adapt to the rapid development of single chip microcomputer and cultivate students' SCM development ability, innovation ability. Using the Proteus software simulation technology, can to a certain extent make up for the shortage, build a virtual experimental platform, can achieve more practice, provide students to learn to disciplinary construction of conditions, has a positive meaning.
In view of this, this article based on the single-chip microcomputer simulation environment, Proteus MICOCHIP company by the PIC microcontroller as the main control chip series with data storage units, combined with peripheral infrared sensor, LCD display, temperature sensing, dc motors, heating DianLuSi, alarm equipment, written in C control program main control chip design combines a automatic temperature monitoring and artificially infrared temperature adjustment is an organic whole, have alarm function of temperature control system. This design fully exert Proteus characteristics, reduce the cost and enhance practicability, benefit in university promotion.
