LHJ—1型森林火险级报警器于1990年10月在东北林业大学通过专家组鉴定,目前已批量生产。黑龙江省的牡丹江、松花江、伊春等林区都在应用。本课题主要为林火预测预报的现代化开辟新路,向自动化发展,进一步提高对林火测报的准确率,以便加强对森林火灾的预防和控制能力。一、技术性能和应用该报警器测报准确率高、结构简单、容易操作、稳定性好、成本低。主要性能为:1.自动采集当地枯枝落叶层的温度、可燃物含水率、风速三项实况数据;2.自动计算、自动查表、自动编制林火等级;3.通过灯光颜色、音调节律直接报警测出火险天气实况等级;4.结合天气演变规律可预报下一天的火险天气等级。
LHJ-1 forest fire alarm level in October 1990 in Northeast Forestry University identified by the expert group, has been mass-produced. Heilongjiang Province, Mudanjiang, Songhua River, Yichun and other forest are in use. This topic mainly opens up a new road for the modernization of forest fire forecasting and automation development, and further improves the accuracy of forestry fire detection in order to strengthen the prevention and control of forest fires. First, the technical performance and application of the alarm reporting accuracy, simple structure, easy operation, good stability, low cost. The main performance is: 1. Automatically collected the local litter layer temperature, combustible moisture content, wind speed three live data; 2. Automatic calculation, automatic look-up table, automatic preparation of fire rating; 3. Through the light color, Direct fire alarm fire detection live weather level; 4 combined with the law of weather evolution can predict the next day’s fire risk weather level.
