摘　　要：针对当前工厂仓库火灾事故频繁发生,设计了一种工厂仓库火灾预警系统。该系统由火灾检测模块与中心接收模块组成,火灾检测模块利用以STM32为控制核心的智能小车在工厂仓库"巡逻",通过加装OV7670图像传感器检测火焰,一旦发现火灾事故发生,立即无线发送预警信息,信息由中心接收模块接收后通过RS 232串口传送给PC机,PC机采取相应救灾措施。实际测试表明,本系统发出预警信息的成功率高,近100%,零误判,时间短。A factory warehouse fire system was designed for the frequent occurrence of the factory warehouse fire accidents. This system is composed of fire detection module and central receiver module. The fire detection module takes STM32 micropro-cessor as master control of the smart car patrolling around the factory warehouse to detect flame by OV7670 image sensor and send the warning information by wireless RF system when discovering fire accident. The central receiver module receives the in-formation and transmits it to PC through RS 232 serial port to adopt the corresponding relief measures. The practical testing re-sult indicates that the system has a nearly 100% success rate in sending warning information.
