Description

Technical Field

[0001] The present invention relates to the technical field of fire warning, and specifically provides an apparatus and a warning method for predicting and warning forestry, agriculture, and grassland composite area fires by region. Background Art

[0002] As is well known, a fire prediction and warning device is a device used to predict and warn of fire situations, reducing the frequency and severity of fires, and it has been widely used in the field of fire warning.

[0003] After retrieval, a patent with the Chinese patent publication number CN110544357A discloses a method, apparatus, and electronic device for predicting and warning forestry, agriculture, and grassland composite area fires by region. It is generally described as follows: including extracting thermal infrared anomaly points of the target forestry, agriculture, and grassland composite area based on multi- or hyperspectral data and thermal infrared data with different temporal, spatial, and spectral resolutions of the target forestry, agriculture, and grassland composite area; estimating the fire occurrence time and fire burning area corresponding to the thermal infrared anomaly points by using the combustion trace method based on multi- or hyperspectral data with different medium and high spatial resolutions of the target forestry, agriculture, and grassland composite area; and predicting and warning forestry, agriculture, and grassland area fires by region within the target forestry, agriculture, and grassland composite area based on the fire occurrence time and fire burning area, combined with the total number of historical forestry, agriculture, and grassland area fires, fire occurrence intensity, and fire occurrence frequency separately counted in the target forestry, agriculture, and grassland composite area. It can effectively improve the accuracy of data extraction and the warning effect.

[0004] When using the existing methods, apparatuses, and electronic devices for predicting and warning forestry, agriculture, and grassland composite area fires by region, it is found that their prediction and warning devices are less flexible during use and cannot comprehensively and efficiently monitor fire prediction and warning in the monitored area. In addition, in other existing video monitoring solutions, a cam or gear is used to transmit an articulated rod for adjusting the pitch angle of the monitoring mechanism. However, in the above structures, the rotation of the monitoring mechanism itself is generally used as the driving force, so that the pitch angle changes during the rotation, resulting in continuous change of the pitch angle and inability to fix it, while the fixed-angle monitoring in other solutions cannot be dynamically changed as needed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-4, a device for predicting and warning forest, agriculture and grassland composite area fires according to the present invention, comprising a monitoring device and a mounting base 1, the monitoring device is mounted on the mounting base 1, and the monitoring device includes an upper fixing pipe 2, a lower fixing pipe 3, a connecting pipe 4, a driving motor 5, a support plate 6, a crank connecting rod 7 and an infrared monitor 8. The top of the upper fixing pipe 2 is sealed, the lower fixing pipe 3 is located below the upper fixing pipe 2, the top and bottom inside the connecting pipe 4 are respectively rotatably connected to the bottom end of the upper fixing pipe 2 and the top end of the lower fixing pipe 3. The driving motor 5 is installed inside the lower fixing pipe 3, a rotating shaft 9 is provided at the top output end of the driving motor 5, a rotating plate 10 is fixed at the top end of the rotating shaft 9, and the outside of the rotating plate 10 is fixedly connected to the middle inside of the connecting pipe 4. A support opening is provided in the middle of the support plate 6, and the support plate 6 is sleeved outside the middle of the connecting pipe 4 through the support opening. The bottom end of the crank connecting rod 7 is rotatably connected to the right side of the top of the support plate 6, a rotating gear 11 is fixed at the top end of the crank connecting rod 7, and an annular rotating rack 12 is sleeved outside the middle of the upper fixing pipe 2. The rotating gear 11 meshes with the rotating rack 12. A connecting rod 13 is rotatably connected to the middle of the crank connecting rod 7. A strip-shaped through groove is provided at one end of the connecting rod 13 close to the crank connecting rod 7, and an electromagnet module is embedded in the through groove. The crank connecting rod 7 is made of a magnetically conductive material. Two monitoring plates 14 are fixed to the right end of the top of the support plate 6. Monitoring shafts 15 are rotatably connected to the tops of the two monitoring plates 14. The left sides of the infrared monitors 8 are respectively connected to the inside of the two monitoring shafts 15. A swing rod 16 is provided at the bottom of the infrared monitor 8, and a swing through hole 17 is provided on the swing rod 16. The right end of the connecting rod 13 is rotatably connected to a swing shaft 18, and the swing shaft 18 is slidably connected to the inside of the swing through hole 17. By driving the driving motor 5 to drive the connecting pipe 4 and the support plate 6 to rotate slowly, the infrared monitor 8 rotates slowly, so as to monitor the surrounding environment in all directions. Moreover, when the support plate 6 rotates, the rotating gear 11 rotates around the rotating rack 12, ensuring that the gear ratio of the rotating rack 12 and the rotating gear 11 is greater than 1, so that the crank connecting rod 7 rotates on the support plate 6. The crank connecting rod 7 drives the connecting rod 13 to move left and right, so that the connecting rod 13 drives the swing rod 16 to swing, and the swing rod 16 drives the infrared monitor 8 to swing up and down, further increasing the monitoring range of the infrared monitor 8, so as to be able to conduct more comprehensive and efficient prediction and warning monitoring of fires in the monitoring area.

[0031] The crank connecting rod 7 is composed of an upper vertical rod, a lower vertical rod, and an intermediate U-shaped rod connected between the two. The upper vertical rod and the lower vertical rod are respectively connected to the bottom of the rotating gear 11 and the top of the support plate 6. The intermediate U-shaped rod is composed of an upper cross rod, a lower cross rod, and an intermediate vertical rod located between the two. The upper cross rod and the lower cross rod are respectively connected to the bottom end of the upper vertical rod and the top end of the lower vertical rod, and both the upper cross rod and the lower cross rod are electrically controlled telescopic rod bodies. An inclination angle sensor is also provided on the rotating gear 11. In response to the output angle value of the inclination angle sensor and the control mode, the upper cross rod and the lower cross rod are controlled to extend to the maximum or contract to the shortest. When the upper cross rod and the lower cross rod contract to the shortest, the upper cross rod, the lower cross rod, the upper vertical rod, and the lower vertical rod are on a vertical straight line.

[0032] It should also be noted that a protective cover 19 is further included. The middle part of the protective cover 19 is sleeved on the outside of the upper fixed pipe 2. The protective cover 19 is located above the rotating gear 11 and the rotating rack 12. The protective cover 19 can reduce the dust between the rotating rack 12 and the rotating gear 11 and ensure the normal rotation of the rotating rack 12 and the rotating gear 11. A humidity monitor 20 is also included. The humidity monitor 20 is installed on the left side of the top of the support plate 6. An air temperature monitor 21 is also included. The air temperature monitor 21 is installed on the rear side of the top of the support plate 6. A wind monitor 22 is also included. The wind monitor 22 is installed on the front side of the top of the support plate 6. The humidity is monitored by the humidity monitor 20, the air temperature is monitored by the air temperature monitor 21, and the wind force is monitored by the wind monitor 22, so that the monitoring device can conduct more comprehensive fire prediction and early warning monitoring. A lifting rod 23 is also included. The lifting rod 23 is installed at the bottom end of the lower fixed pipe 3. The bottom end of the lifting rod 23 is fixed to the top of the installation base 1. The monitoring device is fixed to the installation base 1 through the lifting rod 23. The height of the monitoring device can be adjusted through the lifting rod 23 according to the differences in the agro-forestry-grass complex area, improving the monitoring effect.

[0033] The early warning method of the above-mentioned agro-forestry-grass complex area zoning fire prediction and early warning device includes the following steps:

[0034] Step 1: Install the monitoring device at the monitoring position through the installation base 1, and use the lifting rod 23 to adjust the height of the monitoring device;

[0035] Step 2: During monitoring, the driving motor 5 drives the connecting pipe 4 and the support plate 6 to rotate slowly, so that the infrared monitor 8, the humidity monitor 20, the air temperature monitor 21, and the wind monitor 22 rotate slowly to conduct all-round monitoring of the surrounding environment;

[0036] Step 3: When monitoring different pitch angle regions is required, control the upper crossbar and the lower crossbar to extend to the longest and turn on the electromagnet module. Rotate the gear 11 around the rotating rack 12 to make the crank connecting rod 7 rotate on the support plate 6. The crank connecting rod 7 drives the connecting rod 13 to move left and right, causing the connecting rod 13 to drive the swing rod 16 to swing, and the swing rod 16 drives the infrared monitor 8 to swing up and down, improving the monitoring range of the infrared monitor 8.

[0037] Step 4: When monitoring a fixed pitch angle region is required, when the tilt angle sensor reaches the target angle, turn off the electromagnet module and at the same time control the upper crossbar and the lower crossbar to quickly shorten to the shortest. At this time, the upper crossbar, the lower crossbar, the upper vertical rod, and the lower vertical rod are on a straight vertical line. Rotate the gear 11 around the rotating rack 12 to make the crank connecting rod 7 rotate on its own on the support plate 6, but it cannot drive the swing rod 16 to swing, so that the pitch angle of the infrared monitor 8 is fixed at the target angle.

[0038] Therefore, in the present invention, through the two electronically controlled telescopic crossbars, the electromagnet, and the tilt angle sensor, it is possible to perform multiple modes of monitoring with different variable pitch angles and fixed pitch angles.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
