Description

Technical Field

[0001] The present invention belongs to the technical field of building safety systems, and particularly relates to a collision prevention system for tower crane group operations based on computer vision detection. Background Art

[0002] Tower cranes are one of the most commonly used lifting equipment on construction sites, also known as "tower cranes". They are extended (heightened) section by section (abbreviated as "standard sections") and are used to lift construction raw materials such as steel bars, wooden beams, concrete, and steel pipes for construction. Tower cranes are an essential piece of equipment on construction sites. During the operation of tower crane groups, ground workers need to communicate with the operators on the tower cranes using walkie-talkies. However, due to the perspective deviation of ground personnel, the safety of tower crane operations is not high, especially during the group operations of tower cranes, collisions are extremely likely to occur. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem in the prior art that during the operation of tower crane groups, ground workers need to communicate with the operators on the tower cranes using walkie-talkies, but due to the perspective deviation of ground personnel, the safety of tower crane operations is not high, especially during the group operations of tower cranes, collisions are extremely likely to occur. Therefore, a collision prevention system for tower crane group operations based on computer vision detection is proposed.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A collision prevention system for tower crane group operations based on computer vision detection includes a central main control system, a transmission module, a scheduling module, an early warning module, a processing module, and a calculation module. The central main control system is set on a computer, and the computer includes a first host located inside the tower crane and a second host connected to ground personnel;

[0006] The central main control system is connected to the transmission module, the calculation module, the scheduling module, the early warning module, and the processing module through network signals;

[0007] The central main control system includes the access rights of administrators and a login terminal. The access rights include password verification. The entered password value must be the same as the preset value in the central main control system to enter the central main control system. If they are inconsistent, entry is not allowed. The access rights also include a locking unit. Set the number of incorrect password attempts. When the set incorrect value is reached, the locking unit will lock the access rights, and entry into the central main control system will not be allowed. In the central main control system, set the locking time. When the locking time is reached, the password can be entered again to enter the central main control system.

[0008] Preferably, the login terminal includes a login account and a login password set by the administrator. Matching the login account with the corresponding login password allows access to the central main control system. The central main control system includes a log record that records the operation content after different accounts log in. The log record can set a storage time, and the log record is automatically deleted when the storage time is reached.

[0009] Preferably, the transmission module includes instruction reception, instruction correction, and instruction transmission. Instruction structure and instruction correction are used to transfer information between the first host and the second host. Instruction correction includes instruction withdrawal and re - input of instructions, and the re - input instructions do not affect the order of instruction issuance. Instruction correction includes sorting adjustment, which rearranges the order of multiple issued instructions, and can also lock the order arrangement. After locking, the order of the issued instructions cannot be adjusted.

[0010] Preferably, the calculation module calculates the height and length of the tower crane itself and transfers the values to the central main control system for system recording. The calculation module includes an independent system detection unit that determines the rotation and movement direction of the tower crane in real time.

[0011] Preferably, the warning module includes calculation value comparison, comparing the length and width of the tower crane recorded by the system, and displaying the unreasonable tower crane. The length and width of the tower crane are changed until it meets the safety operation requirements before it can operate.

[0012] Preferably, the scheduling module sets coordinate axes for the area of the installation construction site and sets the loading and unloading positions according to the coordinate axes. The tower crane operates along the specified path and works at the loading and unloading positions shown on the coordinate axes.

[0013] Preferably, when the tower crane operates beyond the positions set on the coordinate axes, the warning module is triggered. The warning module includes checking the work record of the tower crane. When the work record does not meet the regulations, a system pop - up window is triggered. The first host and the second host both receive a dangerous pop - up window prompt. When the system pop - up window is triggered, an alarm will sound in both the tower crane and the underground operation room, and the alarm uses a buzzer.

[0014] Preferably, the processing module includes the function of recording the issued or received instructions and information in the central main control system, recording this work content, and packaging and sending it to the log record unit.

[0015] In summary, the technical effects and advantages of the present invention are as follows: The anti-collision system for group tower operations based on computer vision detection calculates the dimensions of tower cranes through a calculation module and a warning module, and plans a reasonable height difference according to the distribution of the tower crane group, effectively avoiding collisions caused by size problems of tower heights. Moreover, by relying on the scheduling module to establish a coordinate axis at the construction site, when the tower crane group operates, it can also work according to the coordinate directions, eliminating the need for frequent communication between ground personnel and tower crane drivers, improving the construction convenience, ensuring that the material fetching and loading of the tower crane are within a reasonable and safe range, meeting the conditions for safe use, and recording and collecting all tower crane operation records for easy future search, which plays a good restrictive role in standardizing tower crane operations.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Refer to Figures 1 - 5 , the anti-collision system for group tower operations based on computer vision detection includes a central main control system 1, a transmission module 2, a scheduling module 3, a warning module 4, a processing module 5, and a calculation module 6. The central main control system 1 is set on a computer, and the computer includes a first host located inside the tower crane and a second host connected to ground personnel;

[0024] The central main control system 1 is connected to the transmission module 2, the calculation module 6, the scheduling module 3, the warning module 4, and the processing module 5 through network signals;

[0025] The central master control system 1 includes the access rights of the administrator and the login terminal. The access rights include password verification. The entered password value must be the same as the preset value in the central master control system 1 to enter the central master control system 1. If they are inconsistent, entry is prohibited. The access rights also include a locking unit that sets the number of incorrect password attempts. When the set number of incorrect attempts is reached, the locking unit will lock the access rights, and entry into the central master control system 1 will be prohibited. In the central master control system 1, a locking time is set, and after the locking time has elapsed, the password can be entered again to enter the central master control system 1.

[0026] The login terminal includes the login account and login password set by the administrator. Matching the login account with the corresponding login password allows entry into the central master control system 1. The central master control system 1 includes a log record that records the operation content after different accounts log in. The log record can set a retention time, and the log record will be automatically deleted when the retention time has elapsed.

[0027] The transmission module 2 includes instruction reception, instruction correction, and instruction transmission. Instruction structure and instruction correction are used to transfer information between the first host and the second host. Instruction correction includes instruction withdrawal and re-entry of the instruction, and the re-entered instruction will not affect the order of instruction issuance. Instruction correction includes sorting adjustment, which rearranges the order of multiple issued instructions, and the order can also be locked. After locking, the order of the issued instructions cannot be adjusted.

[0028] The calculation module 6 calculates the height and length of the tower crane itself and transfers the values to the central master control system 1 for system recording. The calculation module 6 includes an independent system detection unit that continuously determines the rotation and movement directions of the tower crane.

[0029] The warning module 4 includes calculation value comparison, comparing the length and width of the tower crane recorded by the system and displaying the unreasonable tower crane. The length and width of the tower crane are changed until it meets the safety operation requirements before operation can proceed. The scheduling module 3 includes setting the coordinate axes for the installation construction site area and establishing the loading and unloading positions according to the coordinate axes. The tower crane operates along the specified path and works at the loading and unloading positions shown on the coordinate axes. If the tower crane operates outside the positions set on the coordinate axes, the warning module 4 is triggered. The warning module 4 includes checking the work record of the tower crane. When the work record does not meet the requirements, a system pop-up window is triggered, and both the first host and the second host receive a dangerous pop-up window prompt. When the system pop-up window is triggered, an alarm will sound both inside the tower crane and in the underground operation room. The alarm uses a buzzer. The processing module 5 includes the function of recording the issued or received instructions and information in the central master control system 1, recording this work content, and packing and sending it to the log record unit.

[0030] Working principle: When in use, the central main control system 1 is a server. The management personnel include the ground docking personnel and the tower crane driver. When the accounts and passwords of both match, they can enter the server for operation. The ground personnel set the coordinate axes according to the area of the construction site and set the loading and unloading points on the coordinate axes. The tower crane driver performs construction operations according to the set positions and communicates directly with the ground through the transmission module 2;

[0031] At the same time, the calculation module 6 will set the safety range according to the length, width and verticality of the tower crane and display it through the first host and the second host, which is viewed simultaneously by the tower crane driver and the ground docking personnel, avoiding the frequent calculation of the safety distance during tower crane group operations and effectively improving the operation efficiency. Through the analysis of the records during the tower crane operation by the warning module 4, the loading, unloading and rotation of the tower crane are all within the safety range, and the tower crane exceeding the operation range will be reminded to avoid the occurrence of safety accidents.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
