[0002] Tower crane is a tower crane. With the rise of high-rise and super-high-rise buildings, tower cranes play an increasingly important role in the modern construction process.

[0003] At present, in the construction process, due to the complex conditions on the construction site and the large number of obstacles in the tower crane operation area, the tower crane drivers on the construction site have visual blind spots. Tower crane accidents such as casualties and equipment damage caused by the drivers' visual blind spots occur frequently. The safety performance of tower cranes has become a public safety issue that threatens the lives of construction workers and corporate property. Therefore, how to ensure the safety of tower cranes during operation is an issue that needs to be urgently resolved. Summary of the invention

[0004] In order to reduce the visual blind spots of tower crane drivers at construction sites and reduce the possibility of tower crane accidents caused by visual blind spots, the present application provides a tower crane safety monitoring method, device, equipment, system and storage medium.

[0005] In the first aspect, the present application provides a tower crane safety monitoring method, which adopts the following technical solution:

[0006] A tower crane safety monitoring method, comprising:

[0007] Acquire first video information of the hook area captured by the first camera of the current tower crane at the construction site and second video information of the boom operation area captured by the second camera;

[0008] The display screen in the cab is controlled to display the first video information and the second video information.

[0009] By adopting the above technical solution, during the tower crane hoisting process, the driver can view the first video information and the second video information through the display screen, thereby reducing the visual blind spots of the tower crane driver at the construction site and reducing the possibility of tower crane accidents caused by visual blind spots.

[0010] Optionally, also include:

[0011] Receive third video information of a boom operation area shot by a second camera of at least one other tower crane in the construction site sent by a server, where a shooting time period of the third video information is the same as a shooting time period of the second video information;

[0012] comparing the shooting area in the third video information with the shooting area in the second video information;

[0013] If there is an overlapping area between a shooting area in at least one of the third video information and a shooting area in the second video information, the display screen is controlled to display at least one of the third video information.

[0014] By adopting the above technical solution, the video content in the third video information can provide a reference for the driver to understand the current operating area of ​​the tower crane boom, which is convenient for the driver to fully understand the current operating area of ​​the tower crane boom and reduces the possibility of visual blind spots for tower crane drivers at the construction site.

[0015] Optionally, the third video information includes basic information; if the shooting areas in the plurality of the third video information overlap with the shooting area in the second video information, controlling the display screen to display at least one of the third video information includes:

[0016] Classify the basic information corresponding to the plurality of third video information based on a preset rule to obtain corresponding levels;

[0017] Compare the levels corresponding to the multiple basic information to obtain an optimal level, obtain the third video information corresponding to the optimal level, and use the third video information as the optimal third video information;

[0018] Control the display screen to display the optimal third video information.

[0019] By adopting the above technical solution, there is a possibility that the reference value of the captured third video information is relatively low, so it is necessary to screen multiple third video information with overlapping areas, so that the display screen in the current tower crane gives priority to displaying the third video information with high reference value, reducing the workload of the driver in distinguishing multiple third video information with overlapping areas with the shooting area in the second video information.

[0020] Optionally, the basic information includes a horizontal distance between the second camera of the other tower crane and the second camera of the current tower crane, and the level classification of the basic information corresponding to the plurality of the third video information based on a preset rule includes:

[0026] If at least one of the shooting areas in the fourth video information overlaps with the area to be rotated, the display screen is controlled to display the fourth video information.

[0027] By adopting the above technical solution, when there is an overlapping area between the shooting area in at least one fourth video information and the area to be rotated, the driver can make an early judgment on the possible safety hazards in the area to be rotated based on the content of the fourth video displayed on the display screen, thereby reducing the visual blind spots of the tower crane driver at the construction site and reducing the possibility of tower crane accidents caused by visual blind spots.

[0031] If the current position information of the tower crane arm is within the overlapping range of the first rotation range and the second rotation range, an alarm prompt information is generated to remind the driver.

[0032] By adopting the above technical solution, if the boom of the current tower crane is located inside after it stops, it may affect the normal operation of the booms of other tower cranes. The driver is reminded through an alarm prompt message, so that the driver can adjust the position of the boom of the current tower crane in time, thereby improving the safety of the current tower crane and other tower cranes when the current tower crane stops.

[0057] The present application is further described in detail below in conjunction with the accompanying drawings.

[0058] The present application embodiment provides a tower crane safety monitoring method, which uses a controller installed on the tower crane as an execution subject, and refers to Figure 1 The main process of the method is described as follows (steps S101 to S102):

[0059] Step S101: Acquire first video information of a hook area captured by a first camera of a current tower crane at a construction site and second video information of a boom operation area captured by a second camera;

[0060] The first camera can be installed above the hook. After adjusting the angle, the first camera can shoot the area where the hook is lifted up and down. During the hoisting process through the hook, the first camera can move synchronously with the hook along the length direction of the boom. The second camera is installed at the end of the boom close to the tower crane. The second video information shot by the second camera includes the video along the length direction of the boom and the video below the boom, and the shooting angle is wider than the width of the boom.

[0061] Step S102: Control the display screen in the cab to display the first video information and the second video information.

[0062] During the tower crane hoisting process, the driver can view the first video information and the second video information through the display screen, thereby reducing the visual blind spots of the tower crane driver at the construction site and reducing the possibility of tower crane accidents caused by visual blind spots.

[0063] In one embodiment, the method also includes the following processing: receiving third video information of the boom operating area shot by a second camera of at least one other tower crane in the construction site sent by the server, the shooting time period of the third video information being the same as the shooting time period of the second video information; comparing the shooting area in the third video information with the shooting area in the second video information; if there is an overlapping area between the shooting area in at least one third video information and the shooting area in the second video information, controlling the display screen to display at least one third video information.

[0064] After the second camera is installed, the shooting angle is input according to the basic parameters of the second camera. Since the shooting direction of the second camera on the current tower crane and other tower cranes is consistent with the direction of the boom, the position of the second camera is obtained based on the GPS module, and the shooting area of ​​the second camera is drawn according to the position, shooting direction and shooting angle of the second camera. The second camera can capture the image of the boom and below the boom within the shooting area.

[0065] In this embodiment, refer to Figure 2 In the figure, T1 is the tower crane of the current tower crane, B1 is the boom of the current tower crane, G1 is the hook of the current tower crane, and the acute-angle area with a solid line as the boundary indicated by Q1 is the shooting area of ​​the second camera of the current tower crane; T2 and T3 are the tower cranes of other tower cranes, B2 and B3 are the booms of other tower cranes, G2 and G3 are the hooks of other tower cranes, and the acute-angle areas with dotted lines as the boundaries indicated by Q2 and Q3 are the shooting areas of the second cameras of other tower cranes respectively, and the dotted line of the boundary of the area indicated by Q3 is different in shape from the dotted line of the boundary of the area indicated by Q2.

[0066] When the shooting area of ​​the second camera of the current tower crane intersects with the shooting area of ​​the second camera of other tower cranes, the area of ​​the intersection is the overlapping area. Figure 2In the figure, the closed area formed by the intersection of the solid line of the boundary of the area pointed to by Q1 and the dotted line of the boundary of the area pointed to by Q2 is the overlapping area; the closed area formed by the intersection of the solid line of the boundary of the area pointed to by Q1 and the dotted line of the boundary of the area pointed to by Q3 is also the overlapping area.

[0067] If there is an overlapping area between the shooting area in the third video information and the shooting area in the second video information, it means that the second camera of the other tower crane can shoot the current tower crane boom operating area in the overlapping area from the direction opposite to the shooting direction of the second camera of the current tower crane, which can provide a reference for the driver to understand the current tower crane boom operating area, facilitate the driver to fully understand the current tower crane boom operating area, and reduce the possibility of visual blind spots for tower crane drivers at the construction site.

[0068] In one embodiment, the third video information includes basic information; Figure 2 , when the shooting areas in multiple third video information overlap with the shooting areas in the second video information, when the shooting parameters such as the shooting pixels of the second cameras of other tower cranes are the same, there is a possibility that the reference value of the third video information shot is relatively low due to the long shooting distance, so it is necessary to screen the multiple third video information with overlapping areas, so that the display screen in the current tower crane gives priority to displaying the third video information with high reference value, reducing the workload of the driver to distinguish among the multiple third video information with overlapping areas with the shooting areas in the second video information;

[0069] In order to achieve the above-mentioned effect, the step of controlling the display screen to display at least one third video information includes the following processing: based on preset rules, the basic information corresponding to multiple third video information is graded to obtain corresponding grades; the grades corresponding to the multiple basic information are compared to obtain the optimal grade, and the third video information corresponding to the optimal grade is obtained, and the third video information is used as the optimal third video information; the display screen is controlled to display the optimal third video information.

[0070] The basic information includes the horizontal distance between the second camera of the other tower cranes and the second camera of the current tower crane.

[0071] In one embodiment, the step of leveling the basic information corresponding to multiple third video information based on preset rules includes the following processing: obtaining the first rotation range of the current tower crane arm, and receiving the second rotation range of other tower crane arms corresponding to multiple third video information sent by the server; if there is no overlapping range between the first rotation range and the second rotation range of the current tower crane arm, obtaining the distance interval where the horizontal distance is located; and determining the level of the basic information based on the distance interval.

[0072] Reference Figure 2 to Figure 4According to the GPS module, the location information of the tower crane and the location information of the current tower crane boom are obtained. In the figure, the area indicated by F1 is the first rotation range of the current tower crane boom, and the areas indicated by F2 and F3 are the second rotation ranges of other tower crane booms; the area indicated by F1 is the fan-shaped range in which the boom can rotate, with the tower crane of the current tower crane as the center and the boom as the radius; the areas indicated by F2 and F3 are the fan-shaped range in which the boom can rotate, with the tower crane of other tower cranes as the center and the boom as the radius.

[0073] The controller has a preset first mapping relationship between the distance interval and the level of basic information, refer to Figure 2 , the first rotation range and the second rotation range of the current tower crane arm do not overlap, Figure 2 It can be seen that the third video information captured by the second camera of other tower cranes that are closer to the current tower crane is clearer, so the first mapping relationship is that the smaller the distance interval, the better the level of the corresponding basic information;

[0074] For example, the levels of basic information include the first level, the second level and the third level, wherein the first level is the optimal level. In the first mapping relationship, the distance interval corresponding to the first level is less than 50m, the distance interval corresponding to the second level is 50m to 70m, and the distance interval corresponding to the third level is greater than 70m.

[0075] In one embodiment, the step of leveling the basic information corresponding to multiple third video information based on preset rules includes the following processing: obtaining the first rotation range of the current tower crane arm, and receiving the second rotation range of other tower crane arms corresponding to multiple third video information sent by the server; if there is an overlapping range between the first rotation range of the current tower crane arm and the second rotation range, the overlapping range is an a overlapping range, and the area value of the b overlapping range that overlaps the a overlapping range and the first rotation range is obtained; the ratio between the area value of the b overlapping range and the area value of the a overlapping range is obtained; and the level of the basic information is determined based on the ratio.

[0076] The calculation formula for the above ratio is:

[0077] Ratio = ,in, is the area value of the overlapping range b between the overlapping range a and the first rotation range, The area value of the overlapping range of a.

[0078] The first rotation range and the second rotation range are generated based on the GPS module, and the areas of the first rotation range and the second rotation range are obtained according to the location of the tower crane and the length of the boom, and the corresponding area values ​​are calculated according to the position coordinates of the overlapping range a and the overlapping range b.

[0079] The controller has a preset second mapping relationship between the distance interval and the level of basic information, refer to Figure 3 and Figure 4 , the first rotation range of the current tower crane arm and the second rotation range of other tower cranes have overlapping ranges, Figure 3 and Figure 4 It can be seen that the larger the area value of the overlapping range between the first rotation range and the second rotation range and the overlapping range between the first rotation range, the more images of the working area of ​​the current tower crane arm are contained in the image of the third video information, so the second mapping relationship is that the larger the above ratio is, the better the level of the corresponding basic information is;

[0080] For example, in the second mapping relationship, the ratio interval corresponding to the first level is greater than 70%, the distance interval corresponding to the second level is 50% to 70%, and the distance interval corresponding to the third level is less than 50%.

[0081] In this embodiment, the equipment technician can manually adjust the first pair of mapping relationships and the second mapping relationship according to actual conditions such as the tower crane density and the tower crane boom length in the construction site.

[0082] In one embodiment, the boom needs to be rotated during the work of lifting and transferring goods by the tower crane, and the second camera shoots the boom operating area in real time. Therefore, during the rotation of the boom, the driver cannot know whether there are safety hazards in the direction of the boom rotation. Therefore, in order to enable the driver to know the situation in the boom rotation area in advance, after step S101, the following processing is also included: in response to the operation of the driver of the current tower crane to set the target position for the boom rotation, the area to be rotated of the boom of the current tower crane is obtained and the fourth video information of the boom operating area shot by the second camera of at least one other tower crane in the construction site sent by the server is received; if there is an overlapping area between the shooting area in at least one fourth video information and the area to be rotated, the fourth video information is controlled to be displayed on the display screen.

[0083] When the boom needs to be rotated, the driver sets the target position for the boom rotation, which can be set by keyboard input, selection from the displayed overall map of the construction site, and voice input. The target position coordinates corresponding to the target position and the current position coordinates are obtained based on the GPS module. With the tower crane of the current tower crane as the center and the boom as the radius, the fan-shaped area formed when the boom rotates from the current position to the target position is drawn. This fan-shaped area is the area to be rotated.

[0084] Reference Figure 5In the figure, T4 is the tower crane of the other tower crane, B4 is the boom of the other tower crane, G4 is the hook of the other tower crane, the acute angle area with the dotted line as the boundary indicated by Q4 is the shooting area of ​​the second camera of the other tower crane, the area indicated by F4 is the fan-shaped range in which the boom of the other tower crane can rotate, the position indicated by B11 is the target position of the current tower crane boom rotation, and the fan-shaped area between B1 and B11 is the area to be rotated.

[0085] Reference Figure 5 When there is an overlapping area between the shooting area in at least one of the fourth video information and the area to be rotated, the driver can make an early judgment on the possible safety hazards in the area to be rotated based on the content of the fourth video displayed on the display screen, thereby reducing the visual blind spots of the tower crane driver at the construction site and reducing the possibility of tower crane accidents caused by visual blind spots.

[0086] In this embodiment, the fourth video information may be taken in real time by the second camera of other tower cranes, or it may be historical video information taken by the second camera of other tower cranes within a preset time.

[0087] In one embodiment, there may be multiple tower cranes operating at the construction site, and there is a possibility that the rotation ranges of the tower crane booms overlap. Figure 6 In the figure, T5 is the tower crane of other tower crane, B5 is the boom of other tower crane, G5 is the hook of other tower crane, the acute angle area with dotted line as boundary indicated by Q5 is the shooting area of ​​the second camera of other tower crane, the area indicated by F5 is the fan-shaped range in which the boom of other tower crane can rotate, and the intersection of the area indicated by F5 and the area indicated by F1 is the overlapping range of the boom rotation range.

[0088] If the boom of the current tower crane is located within the first rotation range after it is shut down, it may affect the normal operation of the booms of other tower cranes. Therefore, the method also includes the following processing: obtaining the first rotation range of the boom of the current tower crane, receiving the second rotation range of at least one other boom of the tower crane in the construction site sent by the server, and waiting for the shutdown operation of the driver of the current tower crane; obtaining the position information of the boom of the current tower crane in response to the shutdown operation of the driver of the current tower crane; if the position information of the boom of the current tower crane is within the overlapping range of the first rotation range and the second rotation range, generating an alarm prompt message for reminding the driver.

[0089] The controller can control the buzzer or voice announcer to give an alarm according to the alarm prompt information, thereby reminding the driver so that the driver can adjust the position of the current tower crane boom in time, thereby improving the safety of the current tower crane and other tower cranes when the current tower crane is shut down.
