自动消防炮定位显示控制系统

摘要

Aiming at the problem that the existing automatic fire cannon can't display the location of the fire zone in real time,an automatic fire control system is designed to display the location of the fire area and the fire scene in real time.A STM32F103C8T6 microprocessor is used to construct the positioning and display control circuit of the fire cannon.A NJM2267 chip is used to process the collected video signal,and the fire alarm video channel is selected by the analog switch CH446Q chip,and the control signal is transmitted by using the RS-485 communication mode.The experimental results show that the system can display the location of fire area and the fire scene in real time,which provides great convenience for fire fighting.%针对现有自动消防炮不能实时显示火灾区位置的问题,设计一种能实时显示火灾区域位置和火灾画面的自动消防炮控制系统.系统以STM32F103 C8T6微处理器为核心构建消防炮的定位显示控制电路,利用NJM2267芯片对采集到的视频信号进行处理,采用模拟开关芯片CH446Q选通火灾报警视频通道,使用RS-485通信方式传输控制信号.实验结果表明:该系统能实时地显示火灾区域位置和火灾画面,为消防灭火提供极大的便利.
