Electromagnetic heating control system design

Abstract In recent years, people's living standards continue to improve, so people has higher requirement for winter heating。With the highly development of power electronic technology, a variety of digital control technology is widely used。In this case, a variety of intelligent heating arises at the historic moment, among them, the electromagnetic heating device has its unique advantages。Taking HT46R22 single-chip microcomputer as the controller to realize the digital control of the electromagnetic heating device, greatly improving the electromagnetic heating heating efficiency。

In the design of the hardware circuit includes: main circuit, digital tube display circuit, protection circuit, power circuit, control circuit, such as unit circuit, control circuit, including control level form and synchronization circuit。Electromagnetic cainuanlu main function is as follows: heating, fault alarm, timing, etc,  alarm functions including overheat alarm, over voltage alarm, over-current alarm, etc。By eight digital tube display interface, can display real-time temperature and time。Software part by alarm detection subroutine, keyboard scanning subroutine, timing control subroutine, scanning display subroutine of multiple programs, such as through debugging and code verification, determine the stability of the program is feasible。

This design by using single chip microcomputer as  the  controller, electromagnetic cainuanlu achieve high intelligence, including convenient man-machine interface, automatic timing control, practical functions such  as automatic temperature control and fault alarm, very suitable for family。

Key words：Eletromagnetic heating Single chip microcomputer The man-machine interface Fault alarm
