Description

Technical Field

[0001] This invention relates to the field of building communication technology, and specifically to a communication method, device, equipment, and readable storage medium for collision prevention of lifting machinery. Background Technology

[0002] Crane lifting machinery is a key piece of construction equipment in the entire construction industry and poses a risk of collision. Current methods for preventing collisions with cranes involve transmitting the crane's operational data (from a crane safety monitoring system) via a wireless communication module to all other cranes within the same frequency band (typically 433MHz or 470MHz) and coverage area (received by the wireless communication module). The received operational data is then used to perform algorithmic calculations to prevent collisions. However, this method results in multiple cranes that do not pose a collision risk communicating with each other, leading to bandwidth redundancy and reduced efficiency. Furthermore, the low communication rates of modules at 433MHz and 470MHz result in a high data loss rate and limitations on data stability.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0021] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0022] Example 1

[0023] This embodiment provides a communication method for collision prevention in lifting machinery. Figure 1 A flowchart of the communication method for collision avoidance of this lifting machinery is shown, such as... Figure 1 As shown, the communication method for collision avoidance of lifting machinery may include steps S101 to S106, wherein:

[0024] Step S101: Obtain architectural CAD drawings for construction and extract first mechanical information from the architectural CAD drawings; wherein, the first mechanical information includes the attribute information of the fixed tower crane;

[0025] During construction, numerous lifting machines are often used to vertically transport construction materials and install components. These lifting machines are categorized into fixed tower cranes and mobile cranes (including luffing jib cranes, truck cranes, and overhead pumps, as well as other mobile lifting devices). Fixed tower cranes are anchored to the building, providing greater structural stability, and their properties can be represented in CAD drawings. Mobile cranes can be moved and dismantled at any time, making them suitable for construction sites requiring frequent relocation and non-fixed locations. Since performance data varies depending on the construction location, the property data of mobile cranes needs to be obtained in real-time. The property information of fixed tower cranes can include location coordinates, height, radius, rotation angle, wire rope, tower cap, boom ratio, model, and jib length.

[0026] Step S102: Based on the first mechanical information, the communication area of ​​the fixed tower crane is set, wherein the communication area of ​​the fixed tower crane is in a cellular form;

[0027] By dividing the various collision areas at the construction site into multiple independent small areas and enabling communication within these areas in a cellular pattern, effective communication between tower cranes is achieved, avoiding bandwidth redundancy and low communication efficiency.

[0028] Preferably, step S102 may include steps S1021 to S1024, wherein:

[0029] Step S1021: Extract one of the fixed tower cranes from the first mechanical information as the first center point;

[0030] By taking all fixed tower cranes as the center point for targeted analysis, the accuracy of calculating the communication area of ​​fixed tower cranes can be improved, thereby improving the accuracy of the anti-collision algorithm.

[0031] Step S1022: Determine the fixed tower crane that collides with the first center point by using the tower boom length and position coordinates of the fixed tower crane, and use it as the first peripheral point of the first center point;

[0032] Preferably, step S1022 may include steps A1 to A5, wherein:

[0033] Step A1: Determine the position coordinates and tower arm length of the first center point, and the position coordinates and tower arm length of other fixed tower cranes from the first mechanical information;

[0034] Other fixed tower cranes are those that are fixed in the CAD drawings except for the first center point.

[0035] Step A2: Calculate the distances between the other fixed tower cranes and the first center point using the position coordinates of the first center point and the position coordinates of the other fixed tower cranes respectively;

[0036] Step A3: Sum the jib lengths of other fixed tower cranes and the jib length at the first center point, and compare the sum with the distance;

[0037] Step A4: If the summation result is greater than or equal to the distance, then other fixed tower cranes are determined to be fixed tower cranes that have a collision relationship with the first center point;

[0038] Step A5: If the summation result is less than the distance, then it is determined that there is no collision relationship between other fixed tower cranes and the first center point.

[0039] Step S1023: Obtain the radiation area of ​​the first center point and the radiation area of ​​the first peripheral point from the first mechanical information, and determine the communication area of ​​the first center point based on the radiation area of ​​the first center point and the radiation area of ​​the first peripheral point, wherein the radiation area is the working surface of the crane tower arm.

[0040] Specifically, the coverage area of ​​the tower arm can be a cylindrical area centered on the tower crane, with the tower arm length as the radius and the tower arm height as the height, and the radiation area can be the working surface of the crane tower arm, that is, the cross-section of the cylindrical area.

[0041] Preferably, step S1023 may include steps B1 to B2, wherein:

[0042] Step B1: Determine the first overlapping area between the radiation area of ​​the first center point and the radiation area of ​​the first peripheral point;

[0043] Step B2: Extract the endpoints of the first overlapping region and connect the endpoints of all overlapping regions sequentially to form a closed structure, generating the communication region of the first center point.

[0044] There are two ways to select the endpoints of the first overlapping region:

[0045] In the first method, if the radiation areas of different first peripheral points do not overlap (i.e., they are either separate or tangent), then all the endpoints of each first overlapping area are taken as vertices and connected clockwise or counterclockwise to form a polygonal closed structure, which is the communication area of ​​the first center point.

[0046] In the second approach, if there are overlapping areas (i.e., intersecting areas) between the radiation areas of different first peripheral points, then according to actual needs, a corresponding number (1 or 2) of endpoints are randomly selected from each first overlapping area as vertices and connected clockwise or counterclockwise to generate a closed polygonal structure, which is the communication area of ​​the first center point.

[0047] It should be noted that if the first center point has only one surrounding point, the endpoints of the first overlapping region are generally two. The endpoints of the first overlapping region alone are insufficient to form a closed structure. In this case, a number of feature points can be randomly determined on the boundary line of the radiation region of the first center point, and the feature points can be connected sequentially with the endpoints of the first overlapping region to form a polygon, thereby generating the communication region of the first center point. The number of feature points can be determined by actual needs and is not limited here.

[0048] Furthermore, the communication area of ​​the first center point can also be generated as follows: determine the first peripheral point farthest from the first center point, and generate a closed structure with the distance between the first center point and the first peripheral point as the radius and the first center point as the center, which serves as the communication area of ​​the first center point. Within this communication area, subsequent anti-collision algorithms for lifting machinery will eliminate the first peripheral points that have no collision relationship with the first center point, thus avoiding bandwidth redundancy.

[0049] Step S1024: The communication areas of all first center points are spliced ​​together to generate the communication area of ​​the fixed tower crane.

[0050] Since the number of surrounding points at each first center point is not exactly the same, the communication area of ​​a fixed tower crane is a honeycomb pattern formed by splicing multiple polygons. These polygons can be triangles, quadrilaterals, pentagons, hexagons, etc., and their specific shapes are determined by the number of surrounding points. The splicing can be done at the common boundary line of the communication areas at different center points.

[0051] Step S103: Receive second mechanical information obtained from the sensor monitoring of the fixed tower crane, wherein the second mechanical information includes the attribute information of the mobile machinery;

[0052] The attribute information of mobile machinery may include location coordinates, height, amplitude, rotation angle, wire rope, tower cap, magnification, model, tower arm length, etc.

[0053] Preferably, before receiving the second mechanical information obtained from sensor monitoring of the stationary tower crane, the process includes:

[0054] Determine whether the mobile machinery is within the radiation area of ​​the fixed tower crane; and whether the power of the signal received from the fixed tower crane is greater than a preset threshold.

[0055] If so, the second mechanical information is obtained through the sensors of the fixed tower crane, and the attribute information of the fixed tower crane is sent to the sensors of the mobile machinery;

[0056] If not, the monitoring of the surrounding environment will continue through the sensors on the fixed tower crane.

[0057] Step S104: Set the communication area of ​​the mobile machinery according to the first mechanical information and the second mechanical information;

[0058] Since the location of mobile machinery is not fixed, it is necessary to collect the signals emitted by the sensors of the mobile machinery in real time through the sensors of the fixed tower crane in order to locate the mobile machinery. Furthermore, the communication area of ​​the mobile machinery is set according to the first and second mechanical information, so that the communication area of ​​the mobile machinery is more clearly defined, avoiding bandwidth redundancy and invalid communication.

[0059] Preferably, step S104 may include steps S1041 to S1044, wherein:

[0060] Step S1041: Extract one mobile machine as the second center point;

[0061] Step S1042: Determine the fixed tower crane and mobile machinery that send signals to the sensor at the second center point, and designate them as the second peripheral points of the second center point;

[0062] Step S1043: Obtain the radiation area of ​​the second peripheral point and the radiation area of ​​the second center point from the first mechanical information and the second mechanical information, respectively.

[0063] The determination principles for the second center point, the second perimeter point, the radiation area of ​​the second perimeter point, and the radiation area of ​​the second center point are the same as those for the first center point and the first perimeter point, and will not be elaborated here.

[0064] Step S1044: Determine the second overlapping region between the radiation region of the second center point and the radiation region of the second peripheral point, extract the endpoints of the second overlapping region, and connect the endpoints of all the second overlapping regions in sequence to form a closed structure to generate the communication region of the second center point.

[0065] The communication area of ​​the second center point can be spliced ​​with the communication area of ​​the first center point according to the layout of the construction environment to generate a complete communication area for the construction environment.

[0066] Preferably, after extracting the endpoints of the second overlapping region, the method further includes steps C1 to C3, wherein:

[0067] Step C1: Extract the communication area of ​​the fixed tower crane in the second surrounding points as the target adjustment area;

[0068] Since the location of mobile machinery is not fixed, it may enter the radiation area of ​​a fixed tower crane and become a peripheral point of that center point. In this case, in order to ensure the communication accuracy of the fixed tower crane, it is necessary to make adaptive adjustments to the communication area of ​​the fixed tower crane.

[0069] Step C2: Determine the boundary line closest to the second center point within the target adjustment area;

[0070] Step C3: Connect the endpoints of the boundary line to the endpoints of the second overlapping area in sequence, and enclose the target adjustment area with the other boundary lines to form a closed structure, so as to adjust the communication area of ​​the fixed tower crane.

[0071] It should be noted that when the mobile machinery moves outside the radiation area of ​​the fixed tower crane, the communication area of ​​the fixed tower crane will be restored to the communication area form in step S102 to adapt to the real-time construction environment and reduce bandwidth redundancy.

[0072] Step S105: Construct a three-dimensional communication area structure for the lifting machinery in the building CAD drawings based on the communication areas of the fixed tower crane and the mobile machinery.

[0073] The communication area, being a two-dimensional structure, cannot fully cover all effective communication signals of tower cranes in the construction environment. A three-dimensional construction of the communication areas for both fixed tower cranes and mobile machinery is then implemented, generating a three-dimensional communication area structure capable of enabling all effective communication for the tower cranes. Furthermore, centered on its own lifting machinery, communication and collision calculations are only permitted with lifting machinery with which it is likely to collide. The communication range is small and configured in a cellular pattern, resolving the issue of mutual interference between multiple projects.

[0074] Preferably, step S105 may include steps S1051 to S1052, wherein:

[0075] Step S1051: Obtain the position coordinates, height, and radius of the fixed tower crane from the first mechanical information, and obtain the position coordinates, height, and radius of the mobile machinery from the second mechanical information;

[0076] Step S1052: The communication areas of the fixed tower crane and the mobile machinery are constructed in three dimensions using the position coordinates, height and amplitude of the fixed tower crane and the position coordinates, height and amplitude of the mobile machinery. The three-dimensional construction area is then covered by a wireless communication network to generate a three-dimensional communication area structure.

[0077] The signal frequency of the wireless communication network can be randomly set according to actual construction needs and is not restricted here. In conventional construction environments, wireless signal frequencies are often set to 433MHz or 470MHz, resulting in high channel occupancy, low communication efficiency of lifting machinery, high data packet loss rate, and limitations on data stability. Furthermore, the number of lifting machines that can be used at these frequencies in a single project is limited. This embodiment, by specifically setting the signal frequency, achieves high communication speed and reduces the probability of packet loss. In addition, this three-dimensional communication area structure allows for an unlimited increase in the number of lifting machines without any quantity restrictions, making it highly applicable.

[0078] Step S106: Obtain the operating information of all lifting machinery through three-dimensional communication area structure monitoring to realize collision avoidance calculation of the lifting machinery.

[0079] This three-dimensional communication area structure ensures that lifting equipment at risk of collision can obtain mechanical operation information from each other, so that it can be promptly sent to the anti-collision algorithm for calculation, which is conducive to the orderly construction of lifting machinery.

[0080] This embodiment sets the communication area of ​​the fixed tower crane in a cellular state, dividing the construction site into multiple independent small areas. At the same time, the operation information of the mobile machinery is collected in real time and combined with the communication area of ​​the fixed tower crane to jointly construct the communication area of ​​the mobile machinery, so as to achieve precise coverage of the communication of the mobile machinery. Finally, by constructing a three-dimensional communication area structure through the fixed tower crane and the mobile machinery, effective communication between cranes that have collision relationships is realized, avoiding bandwidth redundancy.
