| Abstract: | The controller of auxiliary electricity heater for solar heater is designed in this paper. This controller is composed of the AT89C51RC2 SCM, LM35 temperature sensor, A/D converter AD7705 and solid-state relay, etc. Special techniques are adopted in the design of the controller, including pulse width modulation technique, subsection integral PID control algorithm. Many safety measures have been taken in the controller, including leaking electricity protection, leaking water protection, extra-high temperature protection, no-water heat defence protection and fault self-diagnosis, etc. |
