[0001] The present invention relates to the technical field of alarm devices, and particularly to an irrigation area environment monitoring and early warning system based on distributed optical fiber sensing. Background Art

[0002] Distributed optical fiber sensing technology is a new type of sensing technology that uses light waves as carriers and optical fibers as media to sense and transmit physical and chemical parameters such as sound waves, vibrations, temperature, and strain in the external environment, and performs intelligent identification and processing. The distributed optical fiber vibration monitoring system is an important branch of distributed optical fiber sensing. By using the scattered light in the optical fiber to monitor and intelligently analyze the pipeline and perimeter dynamics in real time, it can accurately identify events such as external pipeline damage and perimeter intrusion, and accurately locate them.

[0003] An irrigation area refers to an irrigation area with reliable water sources and a system of diversion, transmission, and distribution channels and corresponding drainage channels. It is the product of human economic activities and develops with the development of social economy. Irrigation areas usually have a complete water conveyance, water distribution, irrigation, and drainage engineering system, and can provide irrigation and drainage services according to the needs of crops and considering the water resources and environmental carrying capacity. Usually, planting areas are set near irrigation areas. For planting areas, the problems that are likely to occur are fires and thefts, and these problems are not easily avoided. Installing monitoring has a poor effect on monitoring and cannot give timely alarm reminders. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an irrigation area environment monitoring and early warning system based on distributed optical fiber sensing to solve the problems raised in the above background art.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: An irrigation area environment monitoring and warning system based on distributed optical fiber sensing, including an optical fiber embedding tube, with three-way connectors fixed at both ends of the optical fiber embedding tube. A bottom plate is provided on the top of the optical fiber embedding tube, and the bottom plate is fixed on the ground.

An air detection component is installed on the top of the hollow tube. The air detection component includes a dust collection box. A fan is installed on the front surface of the dust collection box. A temperature sensor is installed at the top end inside the dust collection box, and an air outlet is opened at the bottom of the dust collection box. A cover frame covers the bottom plate on the top after the hollow tube rotates and folds.

[0006] Further, a metal hose is installed at the position of the bottom of the hollow tube corresponding to the bottom plate and the interface of the optical fiber embedding tube. Both ends of the metal hose are fixedly connected with the hollow tube and the optical fiber embedding tube respectively. Fixing bolts are inserted at both ends of the bottom plate. A socket is fixed at the bottom of the optical fiber embedding tube corresponding to the fixing bolts, and the fixing bolts can be threadedly inserted into the socket.

[0007] Further, the driving component further includes a bidirectional electric push rod. The bidirectional electric push rod is fixed on the surface of the bottom plate between the two toothed plates, and a connecting frame is fixed at the extending end of the bidirectional electric push rod. The two connecting frames are fixedly connected with the corresponding toothed plates.

[0008] Further, a second rotating seat is fixed on the other side of the bottom plate where the first rotating seat is located, and a telescopic plate is rotatably installed on the surface of the second rotating seat. An outer plate is fixed on the bottom of the telescopic plate facing the side of the toothed plate. There is a certain distance between the front end of the toothed plate and the outer plate.

[0009] Further, a locking bolt is threadedly inserted at the receiving port of the telescopic plate, and the locking bolt is in pressing contact with the extending end of the telescopic plate. Plug frames are fixed on the backs of the first connection end and the second connection end. The upper and lower ends of the plug frames are hollowed out. Plug blocks are slidably inserted into the plug frames, and the plug blocks are fixedly connected with the extending end of the telescopic plate.

[0010] Further, the anti-theft component further includes a sliding cylinder, and the sliding cylinder is fixed inside the first connection end and the second connection end, and the sliding cylinder is slidably sleeved on the outer surface of the hollow tube.

[0011] Further, a baffle is fixed to the top of the insertion frame, and the baffle blocks a part of the upper hollowed-out area of the insertion frame, and the top of the insertion block is in pressing contact with the baffle.

[0012] Further, a rubber band is fixed to the back of the first connection end and the second connection end, and the other end of the rubber band is fixed to the surface of the bottom plate.

[0013] Further, the air detection component further includes a filter plate, a filter plate is rotatably arranged inside the dust collection box, a weighing element is fixedly installed at the bottom of the filter plate, the weighing element is in contact with the bottom of the filter plate, a rotating cylinder is fixed to one side of the dust collection box facing the hollow tube, and the rotating cylinder is rotatably installed on the outer surface of the hollow tube through a bearing and a torsion spring.

[0014] Further, vertical plates are fixed to the outer surfaces of the first connection end and the second connection end, and insertion posts are fixed to the tops of the vertical plates. Slots corresponding to the insertion posts are arranged on the surface of the rotating cylinder, and the opening ends of the slots of the rotating cylinder are in the same rotation path as the hollow tube.

[0015] Advantages of the present invention:

[0016] 1. When the hollow tube is vertically arranged on the bottom plate in the present invention, a person inserts the insertion post of the vertical plate into the slot of the rotating cylinder. It is a common insertion structure. The opening of the slot is in the same rotation path as the hollow tube, which means that when the insertion post is inserted into the slot, the hollow tube does not rotate. When folded, the rotating cylinder is always limited by the insertion post and cannot rotate through its own torsion spring to keep the fan end facing the planting area. At the same time, when the hollow tube rotates and folds through the driving component, it will not be interfered by the rotating cylinder. After the insertion post is separated from the slot, the rotating cylinder rotates the fan and the dust collection box in a direction parallel to the bottom plate through the action of the torsion spring, which is convenient for subsequent covering of all structures on the bottom plate by the cover frame.

[0017] 2. In the present invention, the height of the connecting line is adjusted by manually adjusting the height of the telescopic plate. The telescopic plate can lock the length through the locking bolt, and then insert the insertion block into the insertion frame. At this time, the first connection end and the second connection end tend to move downward under the traction of the rubber band, and the baffle at the top of the insertion frame is in pressing contact with the insertion block to keep the first connection end and the second connection end from moving downward and maintain the position height. At the same time, the baffle only contacts a part of the surface of the insertion block and can be misaligned by external force extrusion, which neither interferes with the rotation of the hollow tube nor affects the height maintenance of the first connection end and the second connection end.

[0018] 3. When the hollow tube rotates in the present invention, it is elastically pulled by the rubber band. The first connection end and the second connection end slide along the surface of the hollow tube. When the hollow tube rotates completely to the horizontal state, the positions of the connection ends can just meet the state where the connection lines are still taut, avoiding the influence of the slack connection lines on the covering of the cover frame on the bottom plate.

[0019] 4. In the present invention, the bidirectional electric push rod is used to push the connecting frame and the toothed plate to move. The two toothed plates are engaged with the gear to drive the hollow tube to rotate. It can realize the monitoring and early warning of the environment in the vertical state of the hollow tube, and can also realize the folding of the hollow tube. The length of the bottom plate meets the requirement of the opposite folding of the two hollow tubes, which is convenient for the internal structure to be stored and protected after the cover frame covers the bottom plate, and is convenient for people to enter the irrigation area for planting work.

[0020] 5. The hollow tube of the present invention is connected to the optical fiber buried tube through a metal hose. The hollow tube can rotate the angle. Through the insertion of the fixing bolt into the socket, the locking connection between the bottom plate and the optical fiber buried tube can be realized, and the corresponding installation of a section of optical fiber buried tube and a group of bottom plates can be realized. At the same time, the bottom plate can be fixed on the ground through the fixing bolt to maintain the stability of the monitoring and early warning system.

[0021] 6. Compared with the prior art, the present invention arranges the anti-theft component and the air detection component through the driving component and the two unfolded hollow tubes, and cooperates with the optical fiber buried tube to monitor the temperature and prevent fires respectively from underground and above the ground. At the same time, anti-theft early warning is carried out in the enclosed area, which can improve the overall protection effect and can respond more quickly when problems occur.

Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Please refer to Figures 1 to 8, the present invention provides a technical solution: an irrigation area environment monitoring and early warning system based on distributed optical fiber sensing, including an optical fiber embedding pipe 1. Three-way connectors 11 are fixed at both ends of the optical fiber embedding pipe 1. A bottom plate 2 is provided on the top of the optical fiber embedding pipe 1, and the bottom plate 2 is fixed on the ground. Two first rotating seats 21 are symmetrically fixed on the top of the bottom plate 2, and a hollow pipe 3 is rotatably installed in the first rotating seat 21. A buzzer 31 is fixed on the top of the hollow pipe 3, and an alarm lamp 32 is installed on the top of the buzzer 31. The bottom of the hollow pipe 3 passes through the bottom plate 2 and communicates with the optical fiber embedding pipe 1. A driving component 6 is provided on the surface of the bottom plate 2. The driving component 6 includes a gear 64. The gear 64 is rotatably installed on the outside of the first rotating seat 21, and the gear 64 is fixedly connected with the hollow pipe 3. The bottom of the gear 64 is meshed with a rack 63. An anti-theft component 4 is provided on the middle surface of the hollow pipe 3. The anti-theft component 4 includes a first connection end 41 and a second connection end 42. The first connection end 41 and the second connection end 42 are respectively installed at the same height positions on the two hollow pipes 3 on the top of the bottom plate 2, and a connecting wire 43 is electrically connected between the first connection end 41 and the second connection end 42. An air detection component 5 is installed on the top of the hollow pipe 3. The air detection component 5 includes a dust collection box 52. A fan 51 is installed on the front surface of the dust collection box 52. A temperature sensor is installed at the top end inside the dust collection box 52, and an air outlet 55 is opened at the bottom of the dust collection box 52. A cover frame 22 covers the bottom plate 2 on the top after the hollow pipe 3 rotates and folds. The cover frame 22 is an ordinary direction frame, which can wrap the folded hollow pipe 3 to play a role in protection and storage. The optical fiber embedding pipe 1 in this article is the same as the existing distributed optical fiber sensing technology. The three-way connector 11 can achieve multi-angle connection, so that the monitoring area runs through the irrigation area, and it can also perform wrapped anti-theft and environment monitoring on the irrigation area from the periphery. When using the device, the optical fiber embedding pipe 1 is pre-buried underground, and the bottom plate 2 is installed on the ground. The hollow pipe 3 on the bottom plate 2 is unfolded into a vertical shape through the driving component 6, and the temperature and dust on the ground are detected by the air detection component 5 and the anti-theft component 4 to play a role in fire prevention and anti-theft protection monitoring.

[0033] In this embodiment, a metal hose 24 is installed on the bottom plate 2 corresponding to the bottom of the hollow tube 3 and the interface of the optical fiber embedding tube 1. The two ends of the metal hose 24 are respectively fixedly connected to the hollow tube 3 and the optical fiber embedding tube 1. Fixing bolts 23 are inserted at both ends of the bottom plate 2. A socket 12 is fixed to the bottom of the optical fiber embedding tube 1 corresponding to the fixing bolts 23, and the fixing bolts 23 can be threadedly inserted into the socket 12. The hollow tube 3 is connected to the optical fiber embedding tube 1 through the metal hose 24. The hollow tube 3 can rotate at an angle. By inserting the fixing bolts 23 into the socket 12, the locking connection between the bottom plate 2 and the optical fiber embedding tube 1 can be realized, and the corresponding installation of one optical fiber embedding tube 1 and a group of bottom plates 2 can be achieved. At the same time, the bottom plate 2 can be fixed to the ground through the fixing bolts 23 to maintain the stability of the monitoring and warning system.

[0034] In this embodiment, the drive assembly 6 further includes a bidirectional electric push rod 61. The bidirectional electric push rod 61 is fixed on the surface of the bottom plate 2 between the two toothed plates 63, and a connecting frame 62 is fixed to the extending end of the bidirectional electric push rod 61. The two connecting frames 62 are fixedly connected to the corresponding toothed plates 63. A second rotating seat 66 is fixed on the other side of the bottom plate 2 where the first rotating seat 21 is located, and a telescopic plate 67 is rotatably installed on the surface of the second rotating seat 66. An outer plate 65 is fixed to the side of the bottom of the telescopic plate 67 facing the toothed plate 63. There is a certain distance between the front end of the toothed plate 63 and the outer plate 65. The bidirectional electric push rod 61 pushes the connecting frame 62 and the toothed plate 63 to move, and the two toothed plates 63 engage with the gear 64 to drive the hollow tube 3 to rotate. It can realize the monitoring and warning of the environment when the hollow tube 3 is in the vertical state, and it can also realize the folding of the hollow tube 3. The length of the bottom plate 2 meets the requirement that the two hollow tubes 3 are folded towards each other, which is convenient for covering the internal structure with the cover frame 22 after covering the bottom plate 2 for storage and protection, and is convenient for people to enter the irrigation area for planting work.

[0035] In this embodiment, a locking bolt 68 is threadedly inserted at the receiving port of the telescopic plate 67, and the locking bolt 68 is in pressing contact with the extending end of the telescopic plate 67. Plug frames 46 are fixedly provided on the backs of the first connecting end 41 and the second connecting end 42. The upper and lower ends of the plug frame 46 are hollowed out. A plug block 69 is slidably inserted into the plug frame 46, and the plug block 69 is fixedly connected to the extending end of the telescopic plate 67. The anti-theft component 4 further includes a sliding cylinder 44. The sliding cylinder 44 is fixedly provided inside the first connecting end 41 and the second connecting end 42, and the sliding cylinder 44 is slidably sleeved on the outer surface of the hollow tube 3. A baffle 47 is fixedly provided at the top of the plug frame 46, and the baffle 47 blocks a part of the hollowed-out area at the upper end of the plug frame 46. The top of the plug block 69 is in pressing contact with the baffle 47. A rubber band 48 is fixedly provided on the backs of the first connecting end 41 and the second connecting end 42, and the other end of the rubber band 48 is fixedly provided on the surface of the bottom plate 2. The first connecting end 41 and the second connecting end 42 slide along the surface of the hollow tube 3 through the sliding cylinder 44 and are adjusted to an appropriate height. For example, in the fruit tree area, the first connecting end 41, the second connecting end 42, and the connecting line 43 need to be adjusted as high as possible. When someone steals fruits, it is easy to break the connecting line 43. For some areas with a lower height, the position of the connecting line 43 is set slightly lower to prevent people from stepping into the planting area to steal. The height of the connecting line 43 is adjusted by manually adjusting the height of the telescopic plate 67. The telescopic plate 67 can lock the length through the locking bolt 68, and then the plug block 69 is inserted into the plug frame 46. At this time, the first connecting end 41 and the second connecting end 42 are pulled by the rubber band 48 and tend to move downward. However, the baffle 47 at the top of the plug frame 46 is in pressing contact with the plug block 69, keeping the first connecting end 41 and the second connecting end 42 from moving downward and maintaining the position height. At the same time, the baffle 47 only contacts a part of the surface of the plug block 69 and can be misaligned by external force extrusion, neither interfering with the rotation of the hollow tube 3 nor affecting the height maintenance of the first connecting end 41 and the second connecting end 42. When the hollow tube 3 rotates, under the elastic traction of the rubber band 48, the first connecting end 41 and the second connecting end 42 slide along the surface of the hollow tube 3. When the hollow tube 3 rotates completely to a horizontal state, the positions of the connecting ends can just meet the state where the connecting line 43 is still taut, avoiding the connecting line 43 from being slack and affecting the cover frame 22 from covering the bottom plate 2. The technical principle between the first connecting end 41, the second connecting end 42, and the connecting line 43 is the same as that of the existing wire-breaking alarm.

[0036] In this embodiment, the air detection component 5 further includes a filter plate 53. The filter plate 53 rotates inside the dust collection box 52, and a weighing element 54 is fixedly installed at the bottom of the filter plate 53. The weighing element 54 is in contact with the bottom of the filter plate 53. A rotating cylinder 56 is fixed on one side of the dust collection box 52 facing the hollow tube 3, and the rotating cylinder 56 is rotatably installed on the outer surface of the hollow tube 3 through a bearing and a torsion spring. Vertical plates 45 are fixed on the outer surfaces of the first connection end 41 and the second connection end 42, and a plug post 49 is fixed at the top of the vertical plate 45. Slots corresponding to the plug post 49 are provided on the surface of the rotating cylinder 56, and the opening ends of the slots of the rotating cylinder 56 are in the same rotation path as the hollow tube 3. When the hollow tube 3 is vertically arranged on the bottom plate 2, the plug post 49 of the vertical plate 45 is manually inserted into the slot of the rotating cylinder 56. The position of the slot is not shown in the figure and is a common plug-in structure. The fact that the opening of the slot is in the same rotation path as the hollow tube 3 means that when the plug post 49 is inserted into the slot, the hollow tube 3 does not rotate. When folded, the rotating cylinder 56 is always limited by the plug post 49 and cannot rotate through its own torsion spring to keep the fan 51 end facing the planting area. At the same time, when the hollow tube 3 rotates and folds through the driving component 6, it will not be interfered by the rotating cylinder 56. After the plug post 49 is separated from the slot, the rotating cylinder 56 rotates the fan 51 and the dust collection box 52 in a direction parallel to the bottom plate 2 through the action of the torsion spring, which is convenient for subsequently covering all the structures on the bottom plate 2 with the cover frame 22. The fan 51 can be powered by the electric wire sent through the hollow tube 3, sucking the air in the planting area into the dust collection box 52. The dust weight on the filter plate 53 can be monitored by the weighing element 54. If the dust weight is always within a certain range, it is a normal situation. If the weight on the filter plate 53 obtained by the weighing element 54 surges, it may indicate that the air quality is very poor or there is a fire with a lot of floating ashes in the air. Such a situation will trigger the warning of the warning light 32 and the buzzer 31. The filter plate 53 of the dust collection box 52 can be flipped by a motor so that the accumulated dust can be sent out before each monitoring to maintain the accuracy of the weighing measurement.

[0037] When using the device, bury the optical fiber into the pre-buried underground pipe 1. The hollow pipe 3 is connected to the optical fiber burying pipe 1 through the metal hose 24. The hollow pipe 3 can rotate at an angle. Through the insertion of the fixing bolt 23 into the socket 12, the locking connection between the bottom plate 2 and the optical fiber burying pipe 1 can be realized, achieving the corresponding installation of a section of the optical fiber burying pipe 1 and a group of bottom plates 2. At the same time, the bottom plate 2 can be fixed to the ground through the fixing bolt 23. The first connection end 41 and the second connection end 42 slide along the surface of the hollow pipe 3 through the sliding cylinder 44 to adjust them to an appropriate height. For example, in the fruit tree area, the first connection end 41, the second connection end 42, and the connecting wire 43 need to be adjusted as high as possible because it is easy for people to break the connecting wire 43 when stealing fruits. For some areas with a lower height, the position of the connecting wire 43 is set slightly lower to prevent people from stepping into the planting area to steal. This process realizes the adjustment of the height of the connecting wire 43 by manually adjusting the height of the telescopic plate 67. The telescopic plate 67 can lock its length through the locking bolt 68, and then insert the plug block 69 into the inside of the plug frame 46. At this time, the first connection end 41 and the second connection end 42 are pulled by the rubber band 48 and tend to move downward. The baffle 47 at the top of the plug frame 46 is in extrusion contact with the plug block 69, keeping the first connection end 41 and the second connection end 42 from moving downward. Regarding the position height, at the same time, the baffle 47 only contacts a part of the surface of the plug block 69 and can be misaligned by external force extrusion, neither interfering with the rotation of the hollow pipe 3 nor affecting the maintenance of the height of the first connection end 41 and the second connection end 42. When the hollow pipe 3 rotates, under the elastic traction of the rubber band 48, the first connection end 41 and the second connection end 42 slide along the surface of the hollow pipe 3. When the hollow pipe 3 rotates completely to a horizontal state, the positions where the connection ends are located can just meet the state where the connecting wire 43 is still taut, avoiding the slack of the connecting wire 43 from affecting the covering of the cover frame 22 on the bottom plate 2. The fan 51 can be powered by the electric wire sent through the hollow pipe 3. The air on the planting area is sucked into the dust collection box 52. The weight of the dust on the filter plate 53 can be monitored through the weighing element 54. If the dust weight is always within a certain range, it belongs to the normal situation. If the weight on the filter plate 53 obtained by the weighing element 54 surges, it may be that the air quality is very poor or there is a fire with a lot of floating ashes in the air. In such a situation, it will cause warnings from the warning lamp 32 and the buzzer 31. The filter plate 53 of the dust collection box 52 can be driven by the motor to turn over so that before each monitoring, the accumulated dust can be sent out to maintain the accuracy of the weighing measurement.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.
