Problems solved by technology

[0003] At present, the forest fire alarm system generally includes technologies such as satellite remote sensing, video surveillance, and drone patrol. The structure and implementation are relatively complicated, the equipment cost is high and the construction is complicated, so its application in the field of forestry fire prevention monitoring is limited, and it cannot be vigorously promoted to the actual forestry fire prevention application

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0023] Such as Figure 1-2 As shown, the embodiment of the present invention provides a forest fire alarm system based on radiolocation, including: a plurality of monitoring areas, each of which includes four ground stations and a plurality of alarms, and the alarms are arranged in Fire monitoring point, when there is no fire, the alarm is in a silent state, when a fire occurs, the alarm starts and sends signals to the four ground stations, and calculates each of the four ground stations according to the received signal. The distance between the ground station and the alarm is calculated accordin...

Abstract

The invention provides a forest fire prevention alarm system based on radio positioning and relates to the field of radio communication. The system comprises multiple monitoring areas. Each monitoringarea comprises four ground stations and a plurality of alarms; the alarms are arranged at fire outbreak monitoring points; when there is no fire, the alarms are in a silent state; when fire occurs, the corresponding alarm is started and sends signals to the four ground stations; the ground stations calculate the position of the alarm based on the distances between the ground stations and the alarm and respective position coordinates to locate the fire point. The system is low in cost and high in reliability, can automatically predict the accurate position of fire points and can be actually popularized and applied in forestry fire prevention monitoring and alarm.

Description

technical field [0001] The invention relates to the field of radio communication, in particular to a forest fire alarm system based on radio positioning. Background technique [0002] Forestry is the main body of national ecological construction, plays an indispensable role in maintaining economic and social development, and plays a huge role in the process of biological evolution. Forest fire is the enemy of forestry and one of the most serious natural disasters and public crisis events. It is characterized by strong suddenness, great destructiveness, and extremely difficult disposal and rescue. Due to the small range and short distance, manual observation cannot detect fires in time, and it is far from meeting the needs of forest fire prevention monitoring in the whole region. With the development of society and the advancement of science and technology, network and electronic technology is the main development trend of forest fire prevention. [0003] At present, the fo...
