中文摘要:针对当前森林火灾实时预警困难的问题,分 析了碲镉汞(Mercury Cadmium Telluride, MCT)单元红外探测器 用于森林防火领域的可行性。利用MCT红外探测器灵敏度 高、功耗小、成本低的特性,设计了一种基于MCT单元探测器的全方位 扫描式森林防火预警系统。该系统由太阳能和风能提供电源,并由红外 探测器实现对森林火灾中红外辐射信号的采集、放大、处理和成图;通 过RS485总线和GPRS方式实时向上位机监测中心发送数据信息。当出现火情 时,该系统能够及时向森林消防人员发送预警信息,因此可起到及时将火灾消灭在 萌芽阶段的作用。本文系统可在不同的地理环境及气候条件下提供全天候、稳 定可靠的森林火灾预警服务。

Design of Scanning System Based on MCT Detector for Forest Fire-warning
Abstract:To solve the problem that it is difficult to give early fire-warning for forest, the feasibility of using a single element mercury cadmium telluride (MCT) infrared detector in the field of forest fire prevention is analyzed. By utilizing the characteristics of high sensitivity, low power consumption and low cost of single element MCT infrared detectors, an omnidirectional scanning forest fire early warning system based on a single element MCT detector is designed. The system is powered by solar energy and wind energy. Its infrared detector is used to implement the collection, amplification, processing and imaging of the mid-infrared radiation signals of forest fire. The collected signals are sent to the computer monitoring center through RS485 and GPRS. When a fire occurs, the system can send the fire early warning information to firefighters stably in time under various geographic and climate conditions.
