[0001] The present invention relates to the technical field of forestry fire prevention, and in particular to an intelligent forestry fire prevention device. Background Art

[0002] According to the explanation of smart forestry in the "Guiding Opinions on the Development of Smart Forestry in China", its basic connotation refers to making full use of new generation information technologies such as cloud computing, the Internet of Things, mobile Internet, and big data, and forming a new forestry development model with three-dimensional perception, efficient management, prominent ecological value, and integrated internal and external services through the means of perception, materialization, and intelligence. It can be seen that smart forestry is developed based on digital forestry and the application of new generation information technologies such as cloud computing, the Internet of Things, mobile Internet, and big data. On the basis of digital forestry, smart forestry has the essential characteristics of perception, integration, coordination, ecology, and optimization.

[0004] An embodiment of the present invention provides a smart forestry fire prevention device.

[0005] In view of the above problems, the technical solution proposed by the present invention is:

[0006] A smart forestry fire prevention device includes a fixing mechanism, a power supply mechanism, an air supply mechanism, a monitoring mechanism, and a detection mechanism.

The monitoring mechanism is installed inside the fixing box to monitor the environment outside the fixing box. The power supply mechanism is installed inside and on the top of the fixing box and supplies power to the air supply mechanism, the monitoring mechanism, and the detection mechanism.

[0007] As a preferred technical solution of the present invention, a filter is installed on the outer side of the opening close to the detection element, and the filter filters the infrared rays passing through the opening. The detection element includes a shell, and an infrared receiver is installed on one side of the shell. The infrared receiver receives the infrared rays emitted by the infrared transmitter. An amplifier circuit, an ADC converter, and a microprocessor are installed inside the shell. The amplifier circuit increases the signal power emitted by the infrared receiver, the ADC converter converts the analog signal emitted by the infrared receiver into a digital signal, and the microprocessor calculates the signal emitted by the infrared receiver.

[0008] As a preferred technical solution of the present invention, a temperature sensor is installed at the inner bottom of the air box, the ADC converter converts the analog signal emitted by the temperature sensor into a digital signal, and the microprocessor calculates the signal emitted by the temperature sensor.

[0009] As a preferred technical solution of the present invention, the monitoring mechanism includes four groups of wide-angle cameras, a monitoring cavity is provided on the inner top of the fixed box, and the four groups of wide-angle cameras are respectively installed on the four sides of the monitoring cavity, and the side of the fixed box is also provided with a monitoring port connected to the monitoring cavity, and explosion-proof high-temperature glass is installed in the monitoring port, and the wide-angle camera monitors the external environment of the fixed box through the explosion-proof high-temperature glass.

[0010] As a preferred technical solution of the present invention, the microprocessor calculates the signals emitted by the four groups of wide-angle cameras, and a communication module electrically connected to the microprocessor is also installed inside the shell, and the communication module sends the calculation results of the microprocessor to the monitoring room.

[0011] As a preferred technical solution of the present invention, a pair of first connecting ports are opened on the outer side of the fixed box, and a pair of second connecting ports are opened on the top of the air box. The air supply mechanism includes a first air inlet, a first installation cavity, and a second air inlet, and the first air inlet, the first installation cavity, and the second air inlet are connected in sequence. The air supply mechanism also includes a first air outlet, a second installation cavity, and a second air outlet, and the first air outlet, the second installation cavity, and the second air outlet are connected in sequence. The first air inlet and the first air outlet are respectively connected to the pair of first connecting ports, and the second air inlet and the second air outlet are respectively connected to the pair of second connecting ports, and the first installation cavity and the second installation cavity are both installed with exhaust parts.

[0012] As a preferred technical solution of the present invention, a pair of the exhaust parts each include a cross, a motor, and exhaust blades, the motor is installed on one side of the cross, the exhaust blades are located on the other side of the cross, and the output end of the motor is transmission-connected to the exhaust blades.

[0013] As a preferred technical solution of the present invention, the power supply mechanism includes a solar power generation panel and a plurality of batteries. A power supply cavity is provided in the inner middle part of the fixed box. The solar power generation panel is installed on the top of the fixed box through the fixing rod.

[0014] As a preferred technical solution of the present invention, a conical foot is installed at the bottom of the fixing seat.

[0015] In another aspect, the present invention provides a method for a smart forestry fire prevention device, comprising the following steps:

[0016] Step 1: Use four sets of conical feet to fix the device inside and outside the woods, while ensuring that the devices are spaced a certain distance apart and that the fixed location has sufficient sunlight;

[0017] Step 2: start a pair of motors and ensure that the power of the motor in the second installation cavity is smaller than that of the motor in the first installation cavity, so as to draw air outside the device into the air box and discharge the air in the air box out of the device to complete the air circulation in the air box;

[0018] Step 3, start the infrared transmitter, the detection element, and the four groups of wide-angle cameras. The infrared light emitted by the infrared transmitter passes through a pair of openings and is filtered by the filter before being emitted to the infrared receiver. At the same time, the specific wavelength in the infrared light will be absorbed by the carbon dioxide in the air, so the light amplitude of the infrared light changes. After receiving the infrared light, the infrared receiver detects the change value and sends the change value in the form of a signal to the amplifier circuit. The amplifier circuit increases the signal power emitted by the infrared receiver and then sends it to the ADC converter. The ADC converter converts the analog signal into a digital signal and sends it to the microprocessor. The microprocessor obtains the concentration of carbon dioxide based on Beer-Lambert's law. When a fire occurs, the carbon dioxide in the air will increase, resulting in an increase in the value detected by the detection mechanism. The four groups of wide-angle cameras monitor the surrounding environment. When a fire occurs, smoke will be generated.

[0019] Step 4: The communication module sends the calculation results of the microprocessor to the monitoring room. The forest ranger in the monitoring room determines whether a fire has occurred based on the carbon dioxide detection results and the surrounding environmental conditions, so as to extinguish small fires in time to prevent forest fires.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By placing the monitoring mechanism and the detection mechanism inside the device and protecting them with a fireproof and heat-insulating fixed box, the monitoring mechanism and the detection mechanism can be prevented from being burned by the fire. By utilizing the air supply mechanism, the monitoring mechanism and the detection mechanism, the occurrence of forest fires can be prevented.

[0022] 2. Through the use of monitoring and detection agencies, the purpose of double fire prevention can be achieved. When one of them is damaged, the other can continue to prevent the occurrence of forest fires.

[0023] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented according to the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are listed below.
