In spite of recent moves to wean the world of fossil fuels, coal remains the main source of power in many countries. Coal yards are prone to spontaneous ignition, a problem faced in every country that stores or transports coal. Depending on the environment-temperature, ventilation, and the rank of the coal-heating and self-ignition can be a longer or shorter process, but the possibility can never be entirely dismissed. A plethora of studies have modelled this oxidation behavior and proposed countermeasures. Most often, human intervention is necessary, which is both slow and dangerous for the firefighters involved. In this study, we propose to build a complete firefighting solution which is mounted on a number of towers sufficient to cover the area of an open coal yard, complete with redundancy. Each tower includes an inexpensive infrared detector, a water dispenser and a controller programmed to identify areas of elevated temperature, and actuate the dispenser. The heat direction algorithm calculates the parameters to position the water dispenser so that it covers the area. A prototype has been built from inexpensive components to demonstrate the effectiveness at detecting and extinguishing arising fires, and a solution has been costed for the coal yard in the case study. This work has been conducted in collaboration with the managers of the coal yard of a power plant.

尽管最近采取了使世界摆脱化石燃料的举措，但煤炭仍然是许多国家的主要电力来源。煤场容易自燃，这是每个储存或运输煤炭的国家都面临的问题。根据环境温度、通风和煤加热和自燃的等级，过程可能会更长或更短，但这种可能性永远不能完全排除。大量研究模拟了这种氧化行为并提出了对策。大多数情况下，人为干预是必要的，这对所涉及的消防员来说既缓慢又危险。在这项研究中，我们建议建立一个完整的消防解决方案，该解决方案安装在足以覆盖露天煤场区域的多个塔上，并具有冗余性。每个塔都包括一个便宜的红外探测器，一个饮水机和一个控制器，该控制器被编程以识别高温区域并启动饮水机。热量方向算法计算参数以定位饮水机，使其覆盖该区域。使用廉价组件构建了一个原型，以展示检测和扑灭火灾的有效性，并在案例研究中为煤场计算了解决方案的成本。这项工作是与发电厂煤场的管理人员合作进行的。使用廉价组件构建了一个原型，以展示检测和扑灭火灾的有效性，并在案例研究中为煤场计算了解决方案的成本。这项工作是与发电厂煤场的管理人员合作进行的。使用廉价组件构建了一个原型，以展示检测和扑灭火灾的有效性，并在案例研究中为煤场计算了解决方案的成本。这项工作是与发电厂煤场的管理人员合作进行的。
