Application Design of Indoor Wireless Alarm System in Scenic Spots
A wireless alarm system is designed for scenic spots to detect any fire in the area.In the event of a fire,converting smoke,heat and other signals timely into electrical signals and sending to relevant staffcould achieve the goal of alarm and firefighting,and timely protecting people's lives and property safety.The system application design uses STC89C52 single-chip microcomputer as the core controller,and adopts sensor technology and wireless signal transmission technology to achieve the alarm function of scenic spot fires.The system specifically consists of main modules such as fire detection,signal processing,wireless communication,and alarm display.The demonstration result is that the probe of the flame sensor on the slave starts to detect whether the environment is on fire when both the host and the slave are powered on.If it is on fire,the JDY-40 wireless module sends a fire signal to the host through the processing of the single-chip microcomputer.After the host receives the signal,it will sound a buzzer and display the scenic spot address of the fire on the electronic screen.This process completes the alarm.The system is easy to install,adjust,operate,and undergo subsequent maintenance,with a high cost performance ratio.
