| Summary: | 碩士 === 國立彰化師範大學 === 電機工程學系 === 100 === The setting of power shutdown must be released manually before opening traditional electric rolling doors. However, once a fire accident occurs, the power breaker cannot be automatically released due to electric power cut that causes irretrievable regrets. In this thesis, a plug-in wireless fire detection and an automatic door-opening control system is investigated by integrating smoke sensor, temperature detector ,buzzer and applying signal output, input function of 8051 microchip (MCS-51) and RF wireless transmission module. Moreover, the system improves the circuit of traditional auto rolling doors and includes the function of auto detecting to buzz while maintenance is required. Therefore, it can ensure sufficient power to drive the automatic door when a fire accident occurs.
The practical test result of the system shows that the setting for power shutdown can be automatically released to open the door when the indoor temperature is above 47℃ or the smoke concentration is greater than 3.2% obs/m for lasting more than 20 seconds. Since an additional escape door is not required with the system, the escapes channel can be unimpeded.
