The temperature controller is a kind of temperature control device, it user need temperature and the temperature setting of difference to control heater, so as to achieve the purpose of temperature change customer need. Taking AT89C52 single chip microcomputer chip as the core, the research and design can be used in water tank temperature controller. Which describes the application of the temperature controller and its principle, and introduces the AT89C52 single chip microcomputer based on the testing system of hardware design, in order to realize high precision temperature control, the SCM system adopts PID control algorithm and PWM pulse width modulation combination of technology, and illustrates with PID control method to design the temperature control system of the control algorithm and the method to realize the detection of temperature, display, storage and alarm function. Temperature signal chip DS18B20 collection by the temperature, and the way to digital signal transfer to the microcontroller. SCM through to signal processed, so as to achieve the purpose of temperature control. For heating power control, this paper used the bidirectional thyristor control, microcontroller light-coupler to silicon controlled by triggered signals, control thyristor conduction Angle, so as to control the heating wire effective heating power, with LED to indicate the heating wire working condition. This paper has mainly introduced the software design part, here the modularized structure, main module has: temperature signal processing program, keyboard scan and key processing program, LCD display, relay control procedures, program over temperature alarm procedures, etc.
