Abstract

This invention relates to a smoke monitoring and alarming system in the field of communication technology, which includes: a smoke sensor, an A / D converter, a singlechip, a wireless serial transmitter, a wireless serial receiver, an alarming horn, several digital display tubes, 5 seven-segment digital display tubes; the smoke sensor transmits the analog signals to the A / D converter, the A / D converter converts the analog signals into digital signal and outputs to the singlechip, if the signal exceeds the safe range, the signal and the dormitory number are transmitted to the wireless serial receiver of the receiver by the wireless serial transmitter; the wireless serial receiver outputs the signal to the singlechip, and the singlechip controls the alarming horn sound, and displays the danger degree into the digital display tube, thereby the dormitory number of the transmitter is displayed on the 5 seven-segment digital display tubes. The system provided by the invention enables students to hear the warning from the smoke alarm before the fire happens, and know the risk degree and source direction accurately, thereby selecting safe passage for rapid escape.

Description

technical field [0001] The invention relates to an alarm system in the technical field of communication, in particular to a smoke monitoring and alarm system. Background technique [0002] At present, preventive alarm devices are relatively scarce in buildings and dormitory buildings. Although smoke alarms have been installed, their functions are relatively simple. They only make a loud cry to make the whole building escape after hearing it. But because we don't know which direction the danger comes from, and don't know the severity, it is easy to cause confusion, and we can't choose a better escape route, and we can't escape effectively and quickly. [0003] After searching the existing technical documents, it is found that the Chinese patent application number is: 200610150963.5, the publication number is: CN 101174353A, and the name is: household wireless intelligent smoke alarm system. The wireless controlled node for communication, the user mobile phone connected to th...
