DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example: Figure 1-Figure 13 As shown, the present invention provides a technical solution for a real-time monitoring alarm device and an early warning system for construction video based on big data, including a video monitoring structure 1, the video monitoring structure 1 includes a support box 11, an equipment box 14, a camera 17, a speaker 19 and a dual-axis motor 112, an output end of the dual-axis motor 112 is equipped with a detection structure 2, the detection structure 2 includes a clutch 216, a reciprocating screw 215 is fixedly installed at the output end of the clutch 216, the reciprocating screw 215 drives an air supply cleaning component and a detection target control component, the air supply cleaning component includes a transmission frame 1 219, a transmission frame 222, an air drum 223, a mounting frame 7 224 and an air guide elbow 225, the detection target control component includes a mounting frame 5 211, a transmission shaft 1 24 and a gear box 231, both ends of the outer side of the transmission shaft 1 24 are fixedly sleeved with circular frames 23, a mounting frame 8 227 is fixedly connected between the two circular frames 23, an electromagnet 229 is fixedly installed on the outer side of the mounting frame 8 227, and a pressure sensor 230 is fixedly installed inside the mounting frame 8 227.

[0022] Specifically, a plurality of mounting frames 110 are fixedly installed at the bottom of the support box 11 in the video monitoring structure 1, and two threaded holes 111 are provided on the outside of the mounting frame 110. The threaded holes 111 are arranged on one side of the bottom of the support box 11, and the bolts are not affected by the support box 11 when they are installed inside the threaded holes 111. The two threaded holes 111 are arranged perpendicular to each other. The upper threaded holes 111 meet the need to install the video monitoring structure 1 on a horizontal surface, and the side threaded holes 111 meet the need to install the video monitoring structure 1 on a vertical surface. The widening of the mounting frame 110 The adaptable range of buildings is conducive to the installation of the video monitoring structure 1 in various parts of the building. A battery 12 is fixedly connected inside the support box 11, and a charging port 13 is fixedly installed between one side of the battery 12 and the support box 11. The battery 12 is charged through the charging port 13, so that the power stored in the battery 12 is used to power the video monitoring structure 1. When an accident occurs to the power supply equipment of the video monitoring structure 1 at a construction site with a complex construction environment, the video monitoring structure 1 can still work, thereby ensuring the stability of the video monitoring structure 1 in monitoring the construction site.

[0023] An equipment box 14 is fixedly installed on the top of the support box 11, and a dual-axis motor 112 is fixedly installed inside the equipment box 14. A mounting frame 15 is fixedly installed on the output end of the dual-axis motor 112. A sun visor 16 fixedly installed on the top of the outer side of the camera 17 is fixedly connected to the mounting frame 15 to control the dual-axis motor 112 to work. The dual-axis motor 112 drives the mounting frame 15, the sun visor 16 and the camera 17 to rotate slowly, so that the camera 17 moves in a circle to shoot, thereby increasing the shooting range of the camera 17. The video shot by the camera 17 is transmitted to the construction early warning system based on big data through the controller 3. The monitoring and early warning system 4 in the construction early warning system analyzes the video (see below for the analysis process). When the monitoring and early warning system 4 determines that there are safety hazards such as workers not wearing safety helmets and open flames in the video shot by the camera 17, the monitoring and early warning system 4 controls the speaker 19 in the video monitoring structure 1 through the controller 3 to work, and the speaker 19 issues a corresponding warning to remind nearby staff to reduce the probability of safety accidents.

[0024] A clutch 216 is fixedly installed inside the equipment box 14, a transmission shaft three 217 is fixedly installed between the input end of the clutch 216 and the other end of the dual-axis motor 112, a reciprocating screw 215 is fixedly connected to the output end of the clutch 216, a transmission shaft two 212 fixedly connected to the bottom end of the reciprocating screw 215 is fixedly connected to a bevel gear one 213, a bevel gear two 214 is fixedly sleeved on the outer side of a mounting frame five 211 rotatably connected to the equipment box 14, and the bevel gear one 213 is meshed with the bevel gear two 214, so a transmission relationship is formed between the reciprocating screw 215 and the mounting frame five 211 through the transmission shaft two 212, the bevel gear one 213 and the bevel gear two 214. When the reciprocating screw 215 rotates, the mounting frame five 211 rotates.

[0025] A sliding shaft 210 is arranged inside the mounting frame 5 211. The sliding shaft 210, which is arranged as a polyhedron, is in close contact with the inner wall of the mounting frame 5 211. Therefore, the mounting frame 5 211 can move inside the sliding shaft 210, and the rotation of the sliding shaft 210 can drive the mounting frame 5 211 to rotate. A transmission shaft 24 is fixedly installed at one end of the sliding shaft 210, and circular frames 23 are fixedly sleeved at both ends of the outer side of the transmission shaft 24. An electromagnet 229 is fixedly installed on the outer side of the mounting frame 8 227 fixedly connected between the two circular frames 23. The electromagnet 229 is arranged on one side of the top of the support box 11. The rotating camera 17 will not move to the top of the electromagnet 229, and the camera 17 will not affect the operation of the electromagnet 229.

[0026] Under normal circumstances, the electromagnet 229 is in an energized working state, and a magnetic field is generated on the outside of the electromagnet 229 to absorb dust and impurities in the air. At regular intervals, the controller 3 embedded in the battery 12 controls the pneumatic cylinder 27 to work once, and a mounting frame 4 26 is fixedly connected between the extended end of the pneumatic cylinder 27 and the extended end of the telescopic rod 28. A mounting frame 3 25 fixedly connected to one side of the mounting frame 4 26 is rotatably sleeved on the outside of the transmission shaft 1 24, so the working and extended pneumatic cylinder 27 pushes the mounting frame 4 26 to move, and the mounting frame 4 26 drives the mounting frame 3 25, the transmission shaft 1 24, the two circular frames 23 fixedly sleeved on the outside of the transmission shaft 1 24, the mounting frame 8 227 fixedly connected between the two circular frames 23, and the electromagnet 229 fixed on the outside of the mounting frame 8 227 to move, so that the electromagnet 229 slowly moves away from the equipment box 14, so that the electromagnet 229 completely enters the shooting range of the camera 17; When the pneumatic cylinder 27 has finished moving, the camera 17 rotates to align with the electromagnet 229, and the camera 17 takes a video of the top of the electromagnet 229. Then, the pneumatic cylinder 27 contracts to drive the transmission shaft 1 24, the mounting frame 8 227 and the electromagnet 229 to reset back to the inside of the arc plate 21; the video taken by the camera 17 is sent to the construction early warning system based on big data through the controller 3, and the monitoring and early warning system 4 in the construction early warning system analyzes the video. The monitoring and early warning system 4 analyzes the thickness of the dust adsorbed on the outside of the electromagnet 229. When the monitoring and early warning system 4 determines that the amount of dust impurities adsorbed by the electromagnet 229 per unit time exceeds a preset value, the monitoring and early warning system 4 controls the speaker 19 in the video monitoring structure 1 through the controller 3. The speaker 19 issues a corresponding warning to remind nearby staff to take relevant measures to avoid the situation where the concentration of building material particles that are invisible to the naked eye in the construction site is high and cannot be discovered in time, reduce the possibility of construction personnel inhaling building material particles, ensure the personal safety of construction personnel, and improve the effective monitoring range of the video monitoring equipment composed of the video monitoring structure 1 and the detection structure 2.

[0027] An arc groove 115 is provided on the top of the support box 11, and an arc plate 21 is arranged inside the arc groove 115 and fixedly connected to the support box 11. A slant plate 22 is fixedly connected to the top of the arc plate 21 near the side of the air guide bend 225. When the pneumatic cylinder 27 drives the electromagnet 229 to reset, the controller 3 controls the clutch 216 to work and enter the engaged state, and controls the electromagnet 229 to stop working. At this time, a transmission relationship is formed between the transmission shaft three 217 and the reciprocating screw rod 215 through the clutch 216. The working dual-axis motor 112 drives the reciprocating screw rod 215 to rotate through the transmission shaft three 217 and the clutch 216. The rotating reciprocating screw rod 215 is driven by the transmission shaft Second 212, bevel gear one 213 and bevel gear two 214 drive mounting frame five 211 to rotate, the rotating mounting frame five 211 drives transmission shaft one 24 to rotate through sliding shaft 210, and transmission shaft one 24 drives circular frame 23, mounting frame eight 227 and electromagnet 229 to rotate; since mounting frame eight 227 is provided with storage groove three 228 on the outside, and electromagnet 229 is arranged inside storage groove three 228, electromagnet 229 can rotate into the inside of arc plate 21, and during the rotation of electromagnet 229, inclined plate 22 cleans the dust and impurities on the outside of electromagnet 229, so that electromagnet 229 can be quickly cleaned and put into the next work.

[0028] A mounting frame 6 218 is rotatably sleeved on the top of the outer side of the reciprocating screw 215, and the mounting frame 6 218 is fixedly connected to the outer wall of the clutch 216. A transmission frame 1 219 arranged at the bottom of the mounting frame 6 218 is sleeved on the outer side of the reciprocating screw 215 through a nut pair. A transmission frame 222 arranged at the bottom of the transmission frame 1 219 and both sides of the transmission frame 1 219 are fixedly connected with sliding blocks 226. Guide grooves 233 are opened on both sides of the inside of the equipment box 14, and the sliding blocks 226 are arranged inside the adjacent guide grooves 233. Under the action of multiple sliding blocks 226, the transmission frame 1 219 and the transmission frame 2 222 can only move up and down inside the equipment box 14; therefore, when the reciprocating screw 215 rotates, the bevel gear 2 214 drives the transmission frame 1 219 to reciprocate up and down; Since the bottom of the transmission frame 1 219 is fixedly connected with an insertion rod 220, and the insertion rod 220 is arranged on the top of the exhaust pipe 221 fixedly connected to the top of the transmission frame 222, during the downward movement of the transmission frame 1 219, the insertion rod 220 will first be moved downward and inserted into the interior of the transmission frame 222, and then the downwardly moving transmission frame 1 219 will push the transmission frame 222 to move downward. Since the outer bottom rotating sleeve of the reciprocating screw rod 215 is provided with a mounting frame 7 224, the mounting frame 7 224 is fixedly installed in the equipment box 14 and cannot move up and down, and the air drum 223 is fixedly installed between the transmission frame 222 and the mounting frame 7 224, so at this time, the transmission frame 222 moves downward to squeeze the air. Drum 223, since the exhaust pipe 221 on the upper part of the air drum 223 is blocked by the plug rod 220 at this time, the air pressure inside the air drum 223 increases as the transmission frame 222 moves downward, and a pressure relief valve 232 is fixedly connected between one end of the air guide elbow 225 and the mounting frame 7 224. When the air pressure inside the air drum 223 increases to a preset pressure, the pressure relief valve 232 is opened by the air flow, and the air flow is discharged through the air guide elbow 225, and the other end of the air guide elbow 225 penetrates the equipment box 14 and extends to the outside of the equipment box 14. The air guide elbow 225 is arranged on one side of the inclined plate 22, and the air flow blows the dust cleaned by the inclined plate 22, and blows the dust and impurities away from the electromagnet 229; When the transmission frame 219 moves down to the outer end of the reciprocating screw rod 215 and then turns to move upward, the insertion rod 220 leaves the exhaust pipe 221, the air pressure inside the air drum 223 is restored, and the pressure relief valve 232 is automatically closed. Then the transmission frame 219 moves up and resets, and the air pressure inside the air drum 223 is restored and then slowly returns to its original state. A filter screen 113 is fixedly connected to one side of the equipment box 14, and the outside air is filtered by the filter screen 113 and then enters the equipment box 14, so that the inside of the air drum 223 is connected with the outside through the exhaust pipe 221.

[0029] In addition, when the monitoring and early warning system 4 analyzes the video captured by the camera 17 and determines that it is raining, the controller 3 immediately controls the clutch 216 to work in the engaged state for a period of time and then stops working. During this period of time, the dual-axis motor 112 drives the mounting frame 8 227 to rotate 180° through the transmission shaft 3 217, the clutch 216, the reciprocating screw 215, the transmission shaft 212, the bevel gear 1 213, the bevel gear 214, the mounting frame 5 211, the sliding shaft 210, the transmission shaft 1 24 and other structures, and the pressure sensor 230 fixedly installed inside the mounting frame 8 227 faces upward, and the electromagnet 229 is sealed and protected by the mounting frame 8 227, the arc plate 21 and the two circular frames 23; after the concave part of the mounting frame 8 227 faces upward, the mounting frame 8 227 plays a role in storing water; Since the other end of the mounting frame 211 is fixedly connected to the input end of the gear box 231 fixedly installed on the support box 11, the output end of the gear box 231 is fixedly connected to the protective shell 18. When the clutch 216 stops working, the protective shell 18 rotates 90° so that the open end of the telescopic rod 28 faces the support box 11. At this time, the speaker 19 is arranged inside the protective shell 18 at a position away from the support box 11. The protective shell 18 is at a certain distance from the open end of the speaker 19, and rainwater cannot enter the inside of the protective shell 18. In rainy weather, the speaker 19 and the protective shell 18 are rotated 90° to prevent rainwater from damaging and polluting the speaker 19, thereby reducing economic losses.

[0030] After the pressure sensor 230 is used up, the clutch 216 is controlled to engage for a period of time. During this process, the mounting frame 227 rotates 540°, and the electromagnet 229 returns to its facing position. A drainage groove 29 is provided at the end of the arc plate 21 away from the equipment box 14. The water entering the arc plate 21 is discharged through the drainage groove 29 and the arc groove 115 provided on the support box 11. At the same time, the protective shell 18 rotates 270°, and the protective shell 18 and the speaker 19 are reset.

[0031] In addition, such as Figure 2 As shown, a reserved groove 114 is provided at the bottom of the protective shell 18 , and the reserved groove 114 is opened at the top of the supporting box 11 to provide a channel for the protective shell 18 to rotate.

[0032] In addition, such as Figure 3 , Figure 4 and Fig.11 As shown, a storage slot 116 and a storage slot 2 117 are opened on one side of the support box 11, and the pneumatic cylinder 27 arranged inside the storage slot 116 is fixedly connected to the support box 11, and the telescopic rod 28 arranged inside the storage slot 2 117 is fixedly connected to the support box 11, so that the pneumatic cylinder 27 and the telescopic rod 28 are stored, thereby reducing the space occupied by the pneumatic cylinder 27 and the telescopic rod 28, and reducing the space occupied by the video monitoring structure 1 and the detection structure 2 as a whole.

[0033] In addition, the monitoring and early warning system 4 in the construction early warning system includes a sub-wireless communication module 41, a work control module 42 and an alarm data storage module 43. A monitoring and early warning system 4 can be provided with multiple sub-wireless communication modules 41, multiple work control modules 42 and multiple alarm data storage modules 43. Each controller 3 is installed with a sub-wireless communication module 41, a work control module 42 and an alarm data storage module 43. Each controller 3 corresponds to a video monitoring structure 1 and a detection structure 2. It includes a main wireless communication module 44, which forms a communication channel for data transmission with the sub-wireless communication module 41; It includes a video analysis module 45, which analyzes the video; The model storage module 46 includes a model storage module 46, which stores various models trained in advance; It includes a violation determination module 47, which determines whether there is a violation according to the analysis result of the video analysis module 45; It includes an environment simulation module 48, which analyzes the environment parameters in the video; It includes an instruction generation module 49, which generates corresponding control instructions according to the analysis results of the violation determination module 47 and the environment simulation module 48; The video captured by the working camera 17 is transmitted to the main wireless communication module 44 through the sub-wireless communication module 41 on the controller 3. After receiving the video, the main wireless communication module 44 transmits it to the video analysis module 45 and the environmental simulation module 48. The video analysis module 45 compares the video with the violation reference model in the model storage module 46 to determine whether the worker is wearing a safety helmet. The comparison result of the video analysis module 45 is transmitted to the violation determination module 47. The violation determination module 47 determines whether there is a violation based on the comparison result. At the same time, the environmental simulation module 48 analyzes whether there are safety hazards such as open flames, raindrops, and electric sparks in the video. The analysis results of the violation determination module 47 and the environmental simulation module 48 are transmitted to the instruction generation module 49. The instruction generation module 49 generates corresponding control instructions. The control instructions are transmitted to the controller 3 through the main wireless communication module 44 and the sub-wireless communication module 41. The controller 3 controls the detection structure 2 to work.

[0034] The monitoring and early warning system 4 analyzes the video captured by the camera 17 to determine that it is raining, so that the concave part of the mounting frame 8 227 faces upward. After water is stored inside the mounting frame 8 227, the pressure sensor 230 detects the water pressure data, and the detection result of the pressure sensor 230 is fed back to the monitoring and early warning system 4 through the controller 3 in real time; since the shape of the mounting frame 8 227 is fixed, the size and shape of the internal space of the mounting frame 8 227 remain unchanged, and the time for the mounting frame 8 227 to rotate upward to receive rainwater is controllable, the model trained in advance in the model storage module 46 of the monitoring and early warning system 4 can roughly calculate the rainfall at the location of the mounting frame 8 227 per unit time based on the detection data of the pressure sensor 230, and at the same time, the video captured by the camera 17 is fed back to the monitoring and early warning system 4. When the monitoring and early warning system 4 determines that the drainage system of the construction site is working abnormally based on the water accumulation and rainfall at the construction site, the monitoring and early warning system 4 notifies the relevant personnel to avoid abnormal operation of the construction site due to blockage, damage, etc. of the drainage system, resulting in a large amount of economic losses caused by excessive water accumulation in the construction site, thereby reducing safety hazards at the construction site.
