[0039] like Figures 1 to 10 As shown, the present application provides a construction site dynamic monitoring system, including: a cloud platform, a plurality of basic monitoring bases 100 and a plurality of self-propelled monitoring components 200; the basic monitoring base 100 includes an installation base 1, a rotating mechanism 2 is arranged on the top of the installation base 1, a tilting mechanism 3 is arranged on the top of the rotating mechanism 2, a clamping sleeve 4 is hinged on the tilting mechanism 3, the tilting mechanism 3 drives the clamping sleeve 4 to rotate along a vertical plane, a first camera component 13 is arranged on the top of the clamping sleeve 4, a clamping slot is opened at the bottom of the clamping sleeve 4, and a clamping mechanism 41 is arranged in the clamping slot; the self-propelled monitoring component 200 includes a driving seat 8, mounting connecting rods 7 are arranged at both ends of the driving seat 8, a telescopic rod 6 and a fixed block 5 are connected in sequence on the side of the mounting connecting rod 7 away from the driving seat 8, a circular guide rail 9 is arranged on the outer periphery of the side of the telescopic rod 6 close to the fixed block 5, a shifting manipulator 10 is arranged on the slider of the circular guide rail 9, a second camera component 11 is movably connected to the shifting manipulator 10, and the fixed block 5 is movably arranged in the clamping slot.

[0040] A controller and a wireless transmission module are provided in the mounting base 1. The controller is wirelessly connected to the cloud platform via the wireless transmission module. The controller is electrically connected to the tilting mechanism 3, the clamping mechanism 41, and the first camera assembly 13. The controller is also electrically connected to the self-propelled monitoring assembly 200 via the clamping mechanism 41.

[0041] When necessary, the cloud platform controls the self-propelled monitoring component 200 to switch between the two basic monitoring bases 100. The self-propelled monitoring component 200 is combined with the basic monitoring base 100 at the corresponding position, and the shifting manipulator 10 is used to switch the second camera component 11 between the two telescopic rods 6. This can effectively improve the lifting ability of the camera, overcome the dynamically changing obstructions at the construction site, and improve the monitoring ability of the construction site. At the same time, it avoids the space occupation caused by each camera being equipped with a lifting bracket, reduces the probability of collision between moving objects and monitoring devices, and avoids hindering the transportation of materials.

[0042] The second camera assembly 11 includes an image recognition camera. The present application collects images through the image recognition camera to monitor the construction site. At the same time, the size and movement trajectory of the moving object are identified through the image recognition module embedded therein, and then it is determined whether it will collide with the camera. The identification of the size and movement trajectory of the moving object belongs to the prior art. The present application does not involve improvements to the recognition algorithm, and the use of the image recognition camera to identify dynamic obstructions and collision scenes is no longer traced here.

[0043] Specifically, the tilting mechanism 3 includes two mounting plates vertically arranged in parallel on the top of the mounting base 1. The relative end surfaces of the two mounting plates are rotatably provided with connecting shafts. The two connecting shafts are respectively connected to the two sides of the clamping sleeve 4. A tilting motor with an output shaft connected to the connecting shaft is embedded in the top of one of the mounting plates. The rotation of the tilting motor can drive the clamping sleeve 4 to tilt, and then drive the self-propelled monitoring component 200 clamped in the clamping sleeve 4 to tilt. In conjunction with the rotating mechanism 2, the self-propelled monitoring component 200 can also be tilted in all directions.

[0044] Specifically, a first connecting groove 501 is opened on the symmetrical side wall of the fixed block 5, the clamping part of the clamping mechanism 41 movably interferes with the first connecting groove 501, and the contact part between the clamping part of the clamping mechanism 41 and the first connecting groove 501 is provided with mutually adaptive electrical connection components, the clamping part interferes with the first connecting groove 501 to realize mechanical fixation and electrical connection of the fixed block 5, preferably, an in-position sensor 42 is provided on the end side wall of the clamping slide groove.

[0045] The electrical connection component can be a plug and socket combination, which is used to supply power to the self-propelled monitoring component 200 and communicate with the controller.

[0046] Specifically, the driving seat 8 is fixed to one of the mounting connecting rods 7 , a travel motor is embedded in the driving seat 8 , and an output shaft of the travel motor extends to the outside of the driving seat 8 and is connected to the other mounting connecting rod 7 .

[0047] like Fig. 9As shown, when the self-propelled monitoring component 200 switches between the two basic monitoring bases 100, the cloud platform adjusts the orientation of the two clamping sleeves through the rotating mechanism 2 and the tilting mechanism 3 according to the positions of the two basic monitoring bases 100, and the walking motor in the driving seat 8 of the self-propelled monitoring component 200 rotates, so that the two walking arms composed of the mounting connecting rod 7, the telescopic rod 6, and the fixed block 5 are opened at a certain angle, so that the fixed block 5 of the walking arm located at the upper part of the self-propelled monitoring component 200 and equipped with an image recognition camera is aligned with the clamping sleeve of the target basic monitoring base 100, and the corresponding telescopic rod 6 drives the fixed block 5 to be inserted into the preset position of the corresponding clamping sleeve, and the in-place sensor The device 42 can be a pressure sensor, which is used to improve the insertion position accuracy of the fixed block 5. When the fixed block 5 is inserted into the preset position of the corresponding clamping sleeve 4 or the position sensor 42 senses the preset pressure value from the fixed block 5, the corresponding controller controls the corresponding clamping mechanism 41 to clamp the fixed block 5, completes the fixation and connection communication with the self-propelled monitoring component 200, and communicates with the original basic monitoring base 100 through the cloud platform, so that the clamping sleeve 4 of the original basic monitoring base 100 releases the corresponding fixed block 5, and the corresponding telescopic rod 6 retracts to drive the fixed block 5 to separate from the original basic monitoring base 100, completing the switching of the self-propelled monitoring component 200 between the two basic monitoring bases 100.

[0048] like Figure 7 As shown, the clamping mechanism 41 includes a first telescopic mechanism symmetrically arranged on the inner wall of the clamping sleeve, the telescopic end of the first telescopic mechanism is connected to a clamping block, and the electrical connection component is arranged on the clamping block.

[0049] Specifically, the second camera assembly 11 includes a connecting block and a first vertical rotating platform arranged on the top of the connecting block. The first vertical rotating platform is rotationally connected to the image recognition camera to drive the image recognition camera to rotate along a plane perpendicular to the top end surface of the connecting block.

[0050] Since the rotating mechanism 2 and the annular guide rail 9 can drive the image recognition camera to rotate horizontally, the first vertical rotating pan-tilt head only needs to drive the image recognition camera to rotate vertically to achieve the function of an ordinary pan-tilt head. The first vertical rotating pan-tilt head includes two mounting blocks vertically arranged in parallel on the top of the connecting block. Two rotating shafts are respectively rotatably arranged between the opposite end faces of the two mounting blocks. The two rotating shafts are respectively connected to the two sides of the image recognition camera. A horizontal rotating motor that drives the rotating shaft to rotate is arranged inside one of the mounting blocks.

[0051] Specifically, the shift robot 10 includes a horizontal telescopic mechanism fixed on the slider of the annular guide rail 9, two second connecting grooves are symmetrically arranged on the side of the connecting block, and a connecting seat is arranged at the telescopic end of the horizontal telescopic mechanism. The connecting seat is slidably arranged in the second connecting groove and a secondary clamping mechanism is arranged between the connecting seat and the second connecting groove. The connecting seat is fixedly connected to the horizontal telescopic mechanism and electrically connected to the corresponding controller through the secondary clamping mechanism.

[0052] After the self-propelled monitoring assembly 200 is switched between the two basic monitoring bases 100, the image recognition camera needs to be switched between the two telescopic rods 6 by two shifting manipulators 10. Figure 5 As shown, the driving seat 8 drives the two walking arms vertically downward, the telescopic rod 6 is telescoped so that the two annular guide rails are located in the same horizontal plane, the annular guide rail 9 drives the two shift manipulators 10 to be opposite to each other, and the horizontal telescopic mechanism of the shift manipulator 10 on the telescopic rod not clamped by the clamping sleeve 4 drives the corresponding connecting seat to insert into the corresponding second connecting groove on the connecting block, and the secondary clamping mechanism is arranged on the symmetrical inner wall of the second connecting groove, and the structure is the same as the clamping mechanism 41. The connecting seat and the second clamping mechanism are also provided with mutually compatible electrical connection components. The two sets of second clamping mechanisms complete the switching of the image recognition camera between the two telescopic rods 6 by clamping and releasing the two connecting seats.

[0053] Preferably, a collision warning unit 12 is provided on the annular guide rail 9 outside the monitoring angle of view of the image recognition camera. The collision warning unit 12 includes a plurality of sensing probes arranged on the annular guide rail 9. The sensing probes are any one or a combination of infrared sensing probes, ultrasonic probes, and laser probes.

[0054] The specific method of identifying the collision scene is: the image recognition camera itself identifies the collision scene in front of the lens, and the collision warning unit 12 performs warning identification on the collision scene in the blind spot of the lens field of view. Specifically, the moving object entering the preset range is detected by the sensing probe, and the size and movement trajectory of the moving object are identified by timely rotating the image recognition camera, and then the clamping sleeve 4 is controlled to cooperate with the rotating mechanism 2 to drive the self-propelled monitoring component 200 to tilt in various directions or the driving seat 8 controls the two walking arms to bend a certain angle to avoid collision.

[0055] Specifically, the first camera assembly 13 includes a second vertical rotating pan-tilt head and a main camera arranged on the top of the mounting base 1. The second vertical rotating pan-tilt head is rotatably connected to the main camera to drive the main camera to rotate perpendicular to the plane of the top end face of the mounting base. The horizontal orientations of the main camera and the image recognition camera are opposite. The outside of the first camera assembly 13 is provided with a glass cover, and the second vertical rotating pan-tilt head has the same structure as the first vertical rotating pan-tilt head.

[0056] like Figure 1 As shown, when the basic monitoring base 100 is used alone, the tilting mechanism 3 drives the clamping sleeve 4 to rotate, so that the first camera assembly 13 is vertically upward, the rotating mechanism 2 drives the main camera to rotate horizontally, and the second vertical rotating pan head drives the main camera to rotate vertically, so as to monitor the surroundings of the basic monitoring base 100; Figure 2 and Fig.10 As shown, when the basic monitoring base 100 and the walking monitoring component 200 are used in combination, the combination state of the self-propelled monitoring component 200 and the basic monitoring base 100 of the present application is in a normal state, and the two walking arms are driven by the driving seat 8 to be vertically arranged from top to bottom. At this time, the first camera component 13 is vertically downward, and the horizontal directions of the main camera and the image recognition camera mentioned above are opposite, that is, the horizontal directions of the main camera and the image recognition camera are opposite at this time, and the rotation mechanism 2 rotates to drive the image recognition camera and the main camera to rotate horizontally to monitor the surrounding scenes. At the same time, the image recognition camera collects surrounding images for image recognition, so as to identify and dynamically change the obstructions and cooperate with the upper and lower groups of collision warning units 12 to identify the collision scene, such as Fig.10 300a and 300b are dynamically changing obstructions, wherein the dotted portion of the obstruction 300b represents the continuously increasing height of the obstruction. At this time, the self-propelled monitoring component 200 on the basic monitoring base 100 located away from the obstruction 300b can be transferred to the basic monitoring base 100 close to the obstruction 300b. After the transfer is completed, the height of the image recognition camera can be adjusted by adjusting the telescopic length of the telescopic rod of the self-propelled monitoring component 200, and the position of the image recognition camera can be adjusted by the rotating mechanism 2, the tilting mechanism 3, and the annular guide rail 9, so as to adjust the position of the image recognition camera according to the position recognition of the dynamic obstruction, thereby monitoring the obstructed area.

[0057] A solar panel 101 is embedded on the side wall of the mounting base 1, and a battery assembly electrically connected to the solar panel 101 is arranged inside the mounting base 1. The solar panel 101 is used to enhance the endurance and energy saving of the present application and to avoid the present application being unable to connect to electricity. Moving wheels can be arranged at the four corners of the bottom of the mounting base 1 to enhance mobility.

[0058] This application also provides a panoramic monitoring method for a construction site, the specific steps are as follows:

[0059] S100: Arrange a plurality of separate basic monitoring bases 100 and a combination device of the basic monitoring base 100 and the self-propelled monitoring assembly 200 at the construction site to monitor the construction site;

[0060] S200: Switching and adjusting the positions of the main camera and the image recognition camera on the adjacent basic monitoring base 100 by the self-propelled monitoring component 200 to monitor the area blocked by the dynamically changing obstruction;

[0061] S300: The controller identifies the collision scene through the image recognition camera and the collision warning unit 12, and controls the corresponding basic monitoring base 100 and the self-propelled monitoring component 200 to automatically avoid the collision.

Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
