自主火灾探测器(AFD)是一种微型电子组件，将定位功能[使用全球定位系统(GPS)]、通信(分组或语音合成无线电)和火灾探测功能(热、气体、烟雾探测器)整合到一个廉价的可部署组件中。渔农处可透过无线电向地面消防员报告与火警有关的参数，例如温度、一氧化碳浓度或烟雾水平。这些系统被设计成由火灾现场的侦察机插入到火灾中，或者由已经在地面的消防员定位。AFD还可以用作城市-荒地交界处关键资产附近的早期预警装置。AFD现在可以用商业现成的组件来制造。使用现代微电子技术，AFD甚至可以使用简单的干电池组在最长的火灾持续时间(数周)内工作，并且可以设计为在当前的低功率无线电通信技术下具有高达几公里的传输范围。从渔农处捕捉数据流的接收器可以像渔农处本身一样轻便、廉价和便携。廉价的便携式中继器可以用来扩大AFD的范围，并将许多探头协调到一个自主的火灾监测网络中。
An Autonomous Fire Detector (AFD) is a miniature electronic package combining position location capability [ using the Global Positioning System (GPS)], communications ( packet or voice-synthesized radio), and fire detection capability ( thermal, gas, smoke detector) into an inexpensive, deployable package. The AFD can report fire-related parameters, like temperature, carbon monoxide concentration, or smoke levels via a radio link to firefighters located on the ground. These systems are designed to be inserted into the fire by spotter planes at a fire site or positioned by firefighters already on the ground. AFDs can also be used as early warning devices near critical assets in the urban - wildland interface. AFDs can now be made with commercial off-the-shelf components. Using modern micro-electronics, an AFD can operate for the duration of even the longest fire ( weeks) using a simple dry battery pack, and can be designed to have a transmitting range of up to several kilometers with current low power radio communication technology. A receiver to capture the data stream from the AFD can be made as light, inexpensive and portable as the AFD itself. Inexpensive portable repeaters can be used to extend the range of the AFD and to coordinate many probes into an autonomous fire monitoring network.
