Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of position identification, and specifically is a method for accurately identifying an installation position based on a wireless radio frequency standard node. Background Art
[0002] Tower cranes are also called tower cranes. They have a large operating space and are mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. With the digital requirements for safe construction, the concept of digital tower cranes has emerged. The topic of intrinsic safety of tower cranes has been continuously promoted. As a special construction equipment, standard sections are crucial to the safety of tower cranes. Standard sections have different installation positions and different stress deformations, resulting in differences in actual service life. How to effectively monitor standard sections, from traditional whole machine supervision to precise component supervision, to achieve health assessment of standard sections and avoid safety accidents and waste of resources, urgently requires a reasonable solution. Summary of the invention
[0003] In order to solve the above technical problems, the present invention provides a method for accurately identifying the installation position of a standard node based on wireless radio frequency, establishes a system relationship between the electronic tag TID and the standard node, realizes the correspondence between the standard node and the electronic tag, identifies the electronic tags within the vertical range through wireless radio frequency identification technology, and sorts them according to the strength of the sensing signal, so that the system records the position of the standard node.
[0004] To achieve the above object, the present invention adopts the following technical solution: A method for accurately identifying the installation position of a standard node based on wireless radio frequency. The process of identifying the installation position of the standard node is as follows: Step 1: Perform the first signal recognition of the anti-metal flexible tag of the standard section from bottom to top on the ground, determine the standard position F (N) by the signal strength, and record TID (N) and include it in the installation sequence array; Step 2: The RFID device goes up along the standard section, identifies and records the standard section signal, compares it with the installation sequence array, removes the interference data of the recorded electronic tags, sorts the newly added standard section signals according to the signal strength and incorporates them into the installation sequence array; Step 3: Repeat step 2 until all standard sections are identified to form a complete installation sequence array; Step 4: According to the binding relationship between TID and standard section, determine the installation position of each standard section on the tower, and save and generate a complete and ordered standard section installation list.
[0005] Furthermore, the process of the first signal recognition in step 1 is as follows: the signal of the anti-metal flexible label of the standard section is recognized, and the standard section with the strongest signal is determined to be the bottom F(1) and recorded as TID(1); the next is determined to be F(2) and recorded as TID(2); the next is determined to be F(3) and recorded as TID(3); and so on and so forth, F(N) is determined and TID(N) is recorded to form an initialization installation sequence array.
[0006] Furthermore, in step 2, the process of recording the standard node signal is as follows: comparing the installation sequence array, eliminating interference data TID(1) to TID(N), and sorting TID(N+1) to T(N+N) according to signal strength and incorporating them into the installation sequence array.
[0007] Furthermore, the anti-metal flexible labels are located on the same vertical plane. Beneficial Effects
[0008] Since the standard joints are installed in different positions, subjected to different forces and deformations, and have different service lives, the present invention establishes a system relationship between the electronic tag TID and the standard joint, realizes the correspondence between the standard joint and the electronic tag, and records the position of each standard joint. This can effectively monitor the standard joints at each position, manage the service life of the standard joints, realize the health assessment of the standard joints, and avoid safety accidents and waste of resources. DETAILED DESCRIPTION
[0009] The technical solution of the present invention is described in detail below through specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.
[0010] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0011] Radio Frequency Identification (RFID) is a type of automatic identification technology that uses radio frequency to conduct non-contact two-way data communication and read and write recording media (electronic tags or radio frequency cards) to achieve the purpose of identifying targets and exchanging data.
[0012] The tower of a tower crane is built up section by section with standard sections. The system identifies the installation position of the standard section of the tower crane, and can establish a digital model basis for the health assessment of the standard section. The standard section is posted with an anti-metal flexible tag at the nameplate position, and a system relationship is established with the standard section through the electronic tag TID, so that the standard section and the electronic tag correspond. The installation position of the tower crane standard section is a vertical structure installation. The electronic tags within the vertical range are identified through wireless radio frequency identification technology, and sorted according to the strength of the induction signal to realize the system recording the position of the standard section.
[0013] The height of tower cranes ranges from more than ten meters to several hundred meters, and the installation of standard sections also ranges from a few sections to hundreds of sections. The installation position of standard sections is on the same vertical plane and the height of standard sections is greater than 2 meters. Wireless radio frequency identification can effectively distinguish the signal strength. The wireless radio frequency identification equipment recognizes anti-metal flexible tags within a range of 5-8 meters. Personnel are required to climb the tower to record the positions of all standard sections of the tower crane. The process of standard section position recognition is as follows: Step 1: Perform the first identification from bottom to top on the ground, and identify the signal of the anti-metal flexible tag of the standard section. The standard section with the strongest signal is determined to be the bottom F (1) and recorded as TID (1); the next is determined to be F (2) and recorded as TID (2); the next is determined to be F (3) and recorded as TID (3); and so on, determine F (N), record TID (N), form the initialization installation sequence array, and include it in the installation sequence array; Step 2: Since the RFID device has a limited recognition range for anti-metal flexible tags, personnel carry the RFID device to climb the standard section to identify and record the standard section signal. During this process, the RFID device’s recognition range will repeatedly identify the electronic tags recorded below, compare the installation sequence array, remove the interference data TID(1) to TID(N), sort TID(N+1) to T(N+N) according to signal strength and include them in the installation sequence array; Step 3: Repeat step 2 until all standard sections are identified to form a complete installation sequence array.
[0014] Step 4: According to the binding relationship between TID and standard section, determine the installation position of each standard section on the tower, save and generate a complete and ordered standard section installation list, and establish a digital model basis for the health assessment of the standard section.
[0015] In the present invention, the strength of the wireless radio frequency identification signal is used as the basis for judging the distance, that is, the basis for serialization of the standard node. The stability and reliability of the electronic tag are the core indicators of this solution; on the other hand, the anti-metal flexible tag is located in the same vertical plane, which is also an important guarantee to ensure data accuracy.
[0016] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
