ATmega32 ile kumandalı çamaşır makinası kontrol kartı

ATmega32 mikrodenetleyici üzerine kurulu oldukca ilginç ve profosyonel bir proje zaten bu tip gelişmiş projeleri ATMEL serisinde görüyorum

Devrede bazı bölümler opto diyak MOC3043, MOC3023 ile izole edilmiş LCD ve led gösterge kumanda (tahminen rc5) kontrolü ve daha bir çok özellik var

The rotational speed of the motor is controlled by the microcontroller. Its supply voltage 230V is cut by a triac controlled by the ATmega. Indeed, directly powered by 230V motor rotates the spin speed. It should therefore be slow for washing. But the speed control is rendered necessary because the torque varies alot during each revolution of the drum of the distribution and movement of the laundry in the drum. Hence the presence of the tachogenerator of the motor shaft. the ATmega continuously measures the actual speed of the drum (by a function programmed frequency) and compares it with a setpoint. The result is used to adjust the angle of the triac to maintain constant speed (speed control). This is one of the finer points of the program.

The direction of rotation of the motor is selected by switching the connection of the stator relative to the rotor by two relays. The pump and valves are controlled by triacs. The heater is controlled by a relay 230V – 10A.

The microcontroller circuits and low voltage (5V) are isolated from the 230V mains:

feeding a transformer 230V – 2X6V
triacs by opto-triacs detecting zero crossing MOC3043.
cutting the triac motor voltage by an opto-triac NO detecting zero crossing MOC3023 (instantaneous response)

Everything is managed remotely by a remote control for TV! (it avoids touching anything during operation of the machine)
