Logic control circuit Logic control circuit mainly carries out logic control function. It not only collects signals from other blocks, but also generates various driving signals including RELAY&DISC. Besides, an external LED will flash at about 1Hz and a buzzer will make a sound with a frequency of 4KHz every 0.5s for 6 times or continual after internal timer times out. Signals at RELAY will control external relay to decide whether IRON heats or not. Sensor signal processor The core in the whole system is how to correctly detect the position and movement of sensor so that the system can be always under safe control. Thus, it is critical to accurately and correctly deal with signal from sensor in different status and eliminate the noise caused by debounce action from sensor. Here, a unique structure is used to do the high-requirement signal processing. In real application of IRON, sensor needs to be installed according to certain requirements (for example its inclination). Timer Timer block mainly generates various timing signal according to the position of IRON. It is easy to get accurate timer (30s/8min/10min/15min) by using AC 60Hz/50Hz signal as timing reference. As above description, Iron in Horizontal position over 30s will stop heating. While Iron in vertical position over 8min/10min/ 15min will also stop heating. Buzzer A buzzer will make 0.5S sound with a frequency of 4 KHz for 6 times or continual after internal timer timeouts. LED During heating, LED pin is floating and an external LED will turn on. After times out, LED pin outputs pulse and an external LED will flash at about 1Hz. 12-07-0006 PT0259-3 3 07/06/12 PT8A3514/15/16/17/18/19(A/B) Smart Iron Controller ||||||||||||||||
