Problems solved by technology

[0004] In order to prevent the spread of the fire, because the origin of the fire was not discovered in time, the forest was burned in a large area, and it would cause the danger of life and the loss of property.
At present, camera detection or drone detection is used in forest fire prevention equipment, but there are many problems such as high power consumption and high implementation and maintenance costs.

Embodiment 1

[0026] Embodiment 1: as Figure 1-Figure 5 As shown, a low-power forest fire alarm system includes multiple fire detection sensor nodes for detecting whether a fire occurs and where the fire occurs. One fire detection sensor node is arranged every 10 square meters, and each fire sensor node passes through LoRa The wireless module is connected to the LoRa base station, and the LoRa base station is connected to the remote monitoring terminal through the GPRS wireless module.

[0027] The above-mentioned fire detection sensor node includes an infrared sensor, a smoke sensor and a GPS module, the infrared sensor, the smoke sensor and the GPS module are connected to the controller, and the controller is also connected to the transmitting module of the LoRa wireless module, and the infrared sensor is used to receive the flame emitted by the fire The light and smoke sensors are used to detect the size of the smoke after the flame occurs, and the GPS module is used to locate the locat...

Embodiment 2

[0037] Embodiment 2: a kind of low power consumption forest fire alarm system, such as figure 1As shown, the fire alarm system is to install a fire detection sensor node for fire detection every 10 square meters inside the forest. As shown in the installation box 16 of the fire detection sensor node, there is an infrared receiving module 2 for detecting flame inside the box. The receiving end of the infrared receiving module 2 is connected with a flexible optical fiber 7 and arranged outside the box to detect surrounding flame signals. A smoke sensor 3 is also provided outside the installation box, and the power supply 6 and the controller 1 of the fire detection sensor node are connected by wires. , There is also a LoRa wireless module 4 inside the installation box. When a fire occurs, the detection signal from the infrared sensor 2 and the smoke sensor 3 is transmitted to the controller. Start the GPS module to locate the fire location, and send the current location and fire...

Embodiment 3

[0039] Embodiment 3: a kind of alarm method of low power consumption forest fire alarm system, this method comprises the following steps:

[0040] 1) When a fire occurs, the infrared sensor closest to the fire source receives the flame signal from the infrared visible light receiving module through the flexible optical fiber, and the smoke sensor detects a high smoke concentration signal, and sends flame and smoke concentration analog signals to the controller , the main control chip of the controller obtains the corresponding digital quantity through AD conversion, obtains the fusion value through the algorithm in the controller, and compares the fusion value with the set threshold to judge the occurrence of a fire;

[0041] 2) If the calculated fusion value is greater than the set threshold, a fire occurs, and the controller immediately starts the dormant GPS module for rapid positioning, and reads the GPS geographic location value and sends it to the fire alarm system for wi...

Abstract

The invention discloses a low-power-consumption forest fire warning system and a warning method thereof. The low-power-consumption forest fire warning system comprises multiple fire detecting sensor nodes, wherein each fire detecting sensor node is connected to a LoRa base station through a LoRa wireless module, the LoRa base station is connected to a remote monitoring terminal through a GPRS wireless module. The fire situation and geographical location information are detected by adopting the multiple fire detecting sensor nodes and are transmitted to a remote monitoring terminal for early warning, related workers of the remote monitoring terminal perform timely processing and rapidly arrange fire rescue work to minimize damaged area and property loss caused by the fire, monitoring is accurate, reliable and stable, the LoRa wireless module has the advantages of being low power consumption, long service life, wide detection range and convenient implementation and maintenance compared with other wireless modules, the service life can be up to 10 years, and the detection range can be up to 10 km.

Description

technical field [0001] The invention relates to a low-power forest fire alarm system and an alarm method thereof, belonging to the fields of ecological environment monitoring and forest disaster prevention. Background technique [0002] Forest fire is one of the major disasters in forestry worldwide. With the continuous development of afforestation in China, fire prevention has become a top priority. The establishment of forest fire prevention warning is an important basis for realizing the safety and stability of forest fire prevention, an important part of the "prevention of forest fire" construction, and an important carrier of forest protection. With the continuous development of afforestation in China, fire prevention has become a top priority. Forest fire prevention must implement the guideline of "prevention first, active fire fighting" to truly achieve early detection and early resolution. With the maturity of low-power wireless communication technology and the con...
