Description
Technical Field
[0001] The invention belongs to the technical field of building monitoring, and in particular relates to a real-time monitoring device for building status. Background Art
[0002] Nowadays, there are many ways to monitor buildings, such as wall tilt monitoring, wall crack monitoring, and wall hole monitoring, etc. The monitoring of wall cracks, wall holes or other wall damage mostly uses recognition cameras to identify the wall surface in real time. However, nowadays, since the camera is outdoors for a long time, it is easy for the camera surface to be contaminated by external conditions, which leads to the stains on the camera surface being misjudged as a wall damage picture, thereby triggering an alarm. Such false alarms increase the manual burden, and multiple false alarms are likely to cause mental fatigue of the staff, and when a real alarm occurs, it cannot be handled in a timely and effective manner. Summary of the invention
[0003] The purpose of the present invention is to provide a real-time monitoring device for building status, so as to solve the problems raised in the background technology.
[0004] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:
[0005] A real-time monitoring device for building status comprises a body, a camera lens is arranged on the front side of the body, mounting blocks are arranged at the four corners of the front side of the body, a screw rod is rotatably mounted between two corresponding mounting blocks on the left side, a slide rod is rotatably mounted between the other two mounting blocks, a scraper strip is threadedly connected to the screw rod, the other end of the scraper strip is sleeved on the slide rod, the scraper strip is provided with a cleaning pad matching the camera lens, an electric control transmission mechanism is arranged on the upper end of the screw rod, a judgment module, a comparison module, an alarm module and a storage module are also arranged in the body, and the judgment module is electrically connected to the electric control transmission mechanism.
[0006] The lower side of the machine body is fixedly connected with a fixed block, the fixed block is equipped with an articulated seat through a damping shaft, and the lower end of the articulated seat is equipped with a support rod. With such a design, the support rod can support the whole, and the fixed block is equipped with an articulated seat through a damping shaft, so the fixed block can adjust the angle relative to the articulated seat, thereby adjusting the angle of the machine body.
[0007] The lower end of the support rod is equipped with a support plate, and the support plate is equipped with a plurality of fixing nails. With such a design, the staff can directly fix the support plate on the ground through the fixing nails, thereby completing the installation and fixing of the support rod.
[0008] The electric control transmission mechanism includes a motor arranged on the upper side of the machine body, the motor transmission is equipped with a first helical tooth, and the upper end of the screw rod is fixedly connected with a second helical tooth meshing with the first helical tooth through the mounting block. When the motor works in the forward direction, it can drive the first helical tooth to rotate, and the first helical tooth drives the screw rod to rotate in the forward direction through the second helical tooth. Similarly, when the motor works in the reverse direction, it can drive the screw rod to rotate in the reverse direction.
[0009] The machine body is equipped with a protective cover for the motor, the first bevel gear and the second bevel gear. The design of the protective cover can prevent the motor, the first bevel gear and the second bevel gear from being directly exposed to the outside world.
[0010] The real-time monitoring device also includes a control method, which includes the following steps:
[0011] Step 1: Install the machine around the building and ensure that the camera lens can shoot the front of the wall to complete the installation of the machine;
[0012] Step 2: When the detection camera lens transmits the captured image to the judgment module in real time, the judgment module judges and identifies the building exterior wall in the captured image, and judges whether there are cracks, holes or other wall damage on the wall surface in the captured image;
[0013] Step 3: When the judgment module determines that there are cracks, holes or other wall damage on the wall surface in the captured image, the judgment module takes a screenshot of the captured image and saves it in the storage module and records the image as S1, and at the same time controls the electric control transmission mechanism to start working. When the electric control transmission mechanism starts working, it first drives the screw to rotate forward for two seconds. When the screw rotates forward, since the screw is threadedly connected to the scraper bar, the scraper bar can be driven to move upward. When the scraper bar moves upward, the surface of the camera lens is cleaned by the cleaning pad. Then the electric control transmission mechanism drives the screw to rotate in the opposite direction for two seconds, drives the scraper bar to move downward, cleans the camera lens for the second time, and drives the scraper bar to reset. When the scraper bar moves up and down, the sliding bar limits the scraper bar to prevent the scraper bar from swinging.
[0014] Step 4: After the camera lens is cleaned, the judgment module takes a screenshot of the image captured and transmitted by the camera lens at this time and stores it in the storage module, and records the screenshot as S2. At this time, the judgment module controls the comparison module to start working, and the comparison module compares the overlapping images of the S1 image and the S2 image in the storage module. At this time, if the comparison module recognizes that the S2 image does not contain the damaged wall image in the S1 image, and there are no other damaged wall images, then the signal is transmitted to the judgment module. The judgment module determines that the situation is that there is an obstruction on the mirror surface according to the signal transmitted by the comparison module, resulting in the erroneous judgment that the wall is damaged, and then the camera lens continues to work normally;
[0015] Step 5: When the comparison module recognizes that there is still a damaged wall in the S2 picture, but after cleaning the camera lens, the damaged picture in the S2 picture is displaced from the damaged picture in the S1 picture, or cannot be completely overlapped, the comparison module transmits the signal to the judgment module. The judgment module judges based on the transmitted signal that there is an obstruction on the mirror surface, resulting in a false judgment that the wall is damaged. However, the first cleaning did not clean the camera lens. At this time, the judgment module controls the electric control transmission mechanism to start working again, so that the scraper slides up and down to clean the surface of the camera lens for the second time. Then the judgment module recognizes and judges the shooting picture at this time again. If there is no damaged wall in the shooting picture at this time, the camera lens continues to work normally. If the judgment module determines that there is still a damaged picture in the picture taken at this time, the judgment module controls the alarm module to start working. The alarm module works to alarm the staff, so that the staff can check the situation on site and deal with it according to the actual situation.
[0016] Step 6: If the comparison module recognizes that there is still a damaged wall image in the S2 image, and the damaged image in the S2 image completely overlaps with the damaged image in the S1 image, the comparison module transmits the signal to the judgment module. At this time, the judgment module directly controls the alarm module to start working. The alarm module works to alert the staff, so that the staff can check the situation on site and deal with it according to the actual situation.
[0017] The alarm module uses a buzzer to give an alarm.
[0018] The present invention has a simple structure and a reasonable design. When a damaged image is first found on a wall, the lens is cleaned, and then the cleaned captured image is identified and compared with the damaged image of the wall when it is first found, to identify whether a false alarm is caused by stains on the lens. After cleaning, if the damaged image of the second captured image is displaced from that of the first captured image but still exists, it can be determined that the lens was not cleaned thoroughly in the first cleaning, and can be cleaned again. When the first image completely overlaps with the damaged image of the first captured image, an alarm is directly issued. Such a design can perform an initial investigation on the alarm, reduce the possibility of a false alarm, and can timely clean the lens when it is determined that there are stains on the lens.

DETAILED DESCRIPTION
[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0026] like Figure 1-3 As shown, a real-time monitoring device for a building status of the present invention comprises a body 1, a camera lens 11 is arranged on the front side of the body 1, mounting blocks 12 are arranged at the four corners of the front side of the body 1, a screw rod 13 is rotatably mounted between two corresponding mounting blocks 12 on the left side, a slide bar 14 is rotatably mounted between the other two mounting blocks 12, a scraper bar 15 is threadedly connected to the screw rod 13, the other end of the scraper bar 15 is sleeved with the slide bar 14, the scraper bar 15 is provided with a cleaning pad matching the camera lens 11, an electric control transmission mechanism is arranged on the upper end of the screw rod 13, a judgment module 2, a comparison module 21, an alarm module 23 and a storage module are also arranged in the body 1, and the judgment module 2 is electrically connected to the electric control transmission mechanism.
[0027] A fixing block 3 is fixedly connected to the lower side of the machine body 1, and the fixing block 3 is equipped with a hinge seat 31 through a damping shaft, and a support rod 32 is installed at the lower end of the hinge seat 31. In this design, the support rod 32 can support the whole, and the fixing block 3 is equipped with the hinge seat 31 through the damping shaft, so the fixing block 3 can adjust the angle relative to the hinge seat 31, thereby adjusting the angle of the machine body 1.
[0028] The lower end of the support rod 32 is equipped with a support plate 33, and the support plate 33 is equipped with a plurality of fixing nails 34. With such a design, the staff can directly fix the support plate 33 on the ground through the fixing nails 34, thereby completing the installation and fixing of the support rod 32.
[0029] The electric control transmission mechanism includes a motor 35 arranged on the upper side of the body 1, and the motor 35 is equipped with a first bevel gear 36. The upper end of the screw rod 13 passes through the mounting block 12 and is fixedly connected with a second bevel gear 37 meshing with the first bevel gear 36. When the motor 32 works in the forward direction, it can drive the first bevel gear 36 to rotate, and the first bevel gear 36 drives the screw rod 13 to rotate in the forward direction through the second bevel gear 37. Similarly, when the motor 32 works in the reverse direction, it can drive the screw rod 13 to rotate in the reverse direction.
[0030] The body 1 is equipped with a protective cover 38 for the motor 35, the first bevel gear 36 and the second bevel gear 37. The design of the protective cover 38 can prevent the motor 35, the first bevel gear 36 and the second bevel gear 37 from being directly exposed to the outside.
[0031] The real-time monitoring device also includes a control method, which includes the following steps:
[0032] Step 1: Install the machine body 1 around the building and ensure that the camera lens 11 can shoot the front of the wall, thereby completing the installation of the machine body 1;
[0033] Step 2: When the detection camera lens 11 transmits the shooting picture to the judgment module 2 in real time, the judgment module 2 judges and identifies the building exterior wall in the shooting picture, and judges whether there are cracks, holes or other wall damage on the wall surface in the shooting picture;
[0034] Step 3: When the judgment module 2 determines that there are cracks, holes or other wall damage on the wall surface in the captured image, the judgment module 2 takes a screenshot of the captured image and saves it in the storage module and records the image as S1, and at the same time controls the electric control transmission mechanism to start working. When the electric control transmission mechanism starts working, it first drives the screw 13 to rotate forward for two seconds. When the screw 13 rotates forward, since the screw 13 is threadedly connected with the scraper 15, the scraper 15 can be driven to move upward. When the scraper 15 moves upward, the surface of the camera lens 11 is cleaned by the cleaning pad. Then the electric control transmission mechanism drives the screw 13 to rotate in the opposite direction for two seconds, drives the scraper 15 to move downward, cleans the camera lens 11 for the second time, and drives the scraper 15 to reset. When the scraper 15 moves up and down, the slide bar 14 limits the scraper 15 to prevent the scraper 15 from swinging.
[0035] Step 4: After the camera lens 11 is cleaned, the judgment module 2 takes a screenshot of the image captured and transmitted by the camera lens 11 and stores it in the storage module, and records the screenshot as S2. At this time, the judgment module 2 controls the comparison module 21 to start working. The comparison module 21 compares the overlapping images of the S1 image and the S2 image in the storage module. At this time, if the comparison module 21 recognizes that the S2 image does not contain the damaged wall image in the S1 image, and there are no other damaged wall images, the signal is transmitted to the judgment module 2. The judgment module 2 determines that the situation is that there is an obstruction on the mirror surface according to the signal transmitted by the comparison module 21, resulting in the erroneous judgment that the wall is damaged, and then the camera lens 11 continues to work normally;
[0036] Step 5: When the comparison module 21 recognizes that there is still a damaged wall in the S2 picture, but after the camera lens 11 is cleaned, the damaged picture in the S2 picture is displaced from the damaged picture in the S1 picture, or cannot be completely overlapped, the comparison module 21 transmits the signal to the judgment module 2. The judgment module 2 judges based on the transmitted signal that at this time, there is an obstruction on the mirror surface, resulting in a false judgment that the wall is damaged. However, the first cleaning did not clean the camera lens 11. At this time, the judgment module 2 controls the electric control transmission mechanism to start working again, so that the scraper 15 slides up and down to clean the surface of the camera lens 11 for the second time. Then the judgment module 2 recognizes and judges the shooting picture at this time again. At this time, if there is no damaged wall in the shooting picture, the camera lens 11 continues to work normally. If the judgment module 2 determines that there is still a damaged picture in the picture taken at this time, the judgment module 2 controls the alarm module 23 to start working. The alarm module 23 works to alarm the staff, so that the staff can check the situation on site and deal with it according to the actual situation.
[0037] Step six: If the comparison module 21 recognizes that there is still a damaged wall image in the S2 image, and the damaged image in the S2 image completely overlaps with the damaged image in the S1 image, the comparison module 21 transmits the signal to the judgment module 2. At this time, the judgment module 2 directly controls the alarm module 23 to start working. The alarm module 23 works to alarm the staff, so that the staff can check the situation on site and deal with it according to the actual situation.
[0038] The alarm module 23 alarms in the form of buzzing.
[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
