提出了一种光电烟温复合探测器，它利用光敏元件接收烟雾粒子对红外脉冲光的散射信号，并利用半导体感温元件检测温度变化，经大险探测算法处理后输出相应的报警信号。这种探测器不仅保留了普通光电烟雾探测器对阴燃火的高探测灵敏度，而且克服了普通光电烟雾探测器不能响应带温升的黑烟火的致命缺点，同时探测器还具有利用火险探测算法处理传感信号、产生多级报警和传感器与控制器通信等智能化．功能，可以与控制器构成火险自动探测系统。
A photoelectric smoke temperature composite detector is proposed, which uses light-sensitive elements to receive the scattering signals of smoke particles to infrared pulsed light. The semiconductor temperature sensing element is used to detect the temperature change, and the corresponding alarm signal is output after being processed by the large-scale detection algorithm. This detector not only retains the common photoelectric smoke detectors on the high detection sensitivity of smoldering fire, but also overcome the common photoelectric smoke detectors can not respond to the fatal flaws of the dark smoke with temperature rise, while the detector also has the use of fire detection algorithm Processing sensor signals, generating multi-level alarm and sensor and controller communication and other intelligent. Function, with the controller constitutes a fire automatic detection system.
