Description

Technical Field

[0001] The present invention relates to the management technology of aluminum alloy formwork for construction, in particular to a system and method for generating and identifying identification codes of aluminum alloy formwork for construction. Background Art

[0002] Due to the characteristics of light weight, high strength, many turnover times, low amortization cost, high recycling value, etc., aluminum alloy formwork has become a new technology in the construction industry that is vigorously promoted by the Ministry of Housing and Urban-Rural Development.

[0003] Since the price of aluminum alloy formwork is relatively expensive and it can be recycled 150 - 300 times, therefore, carrying out informatization management on aluminum alloy formwork and identifying and managing each aluminum alloy formwork is an effective way to improve the turnover utilization rate of aluminum alloy formwork.

[0004] However, after the aluminum alloy formwork is used, large debris such as concrete and mortar will adhere to its surface. If it is not cleaned and repaired, it cannot be used again. Therefore, in the maintenance process of old aluminum formwork, a "dust cleaning" process needs to be set.

[0005] The traditional dust cleaning method is to rely on manual soaking and pickling to remove the residual concrete, mortar and other debris on the surface of the aluminum formwork. However, the pickling waste liquid pollutes the environment and is also very harmful to the human body. In recent years, shot blasting method and heating method have been developed, which can also achieve automatic dust cleaning of aluminum alloy formwork.

[0006] At present, all kinds of dust cleaning technologies require the aluminum alloy formwork to carry out maintenance operations under extremely harsh conditions. For example, the aluminum alloy formwork needs to be in a high-frequency impact, high-temperature and corrosive environment, and finally repainted for renovation.

[0007] In the prior art, generally, identification technologies such as RFID radio frequency chips, two-dimensional codes and barcodes are used to encode and manage aluminum alloy formwork. However, the application of conventional identification technologies such as RFID radio frequency chips, two-dimensional codes and barcodes is greatly limited by high-frequency impact, high temperature and corrosive environment. The RFID radio frequency chip is easily corroded and damaged by high-frequency impact, and the two-dimensional code and barcode are also easily worn during use and easily corroded and damaged during the dust cleaning process and become invalid, resulting in the inability to effectively identify each aluminum alloy formwork during subsequent reuse, and ultimately leading to the inability to effectively manage the entire set of aluminum alloy formwork and not knowing which aluminum alloy formwork is damaged, scrapped or lost.

[0008] For example, the patent application number: CN201820286879.4, publication number: CN208251611U, discloses an aluminum alloy formwork embedded with a radio frequency identification chip, which installs a radio frequency chip on the aluminum alloy formwork and has the disadvantage of being easily corroded and damaged by high-frequency impact during the dust cleaning process.

[0009] For another example, patent application number: CN201811543210.X, publication number: CN109436647A, discloses an automatic storage coding device and method for aluminum templates, wherein the aluminum template recognition device is surrounded by four distance detection units to form a rectangle, which can surround the aluminum template in the middle; the four distance detection units respectively detect the distance between each point on the four directions of the aluminum template and the corresponding point on the distance detection unit, and send the distance information to the shape generation unit, and the shape generation unit generates the position coordinates of each point on the periphery of the aluminum template in the coordinate system according to the distance information obtained by the four distance detection units and the position information of the four distance detection units themselves, thereby forming an aluminum template. The shape of the template, the X-axis and Y-axis of the coordinate system correspond to the slide rails of two adjacent distance detection units respectively; the outer lines of the aluminum template include straight lines and holes; the shape generation unit determines whether the aluminum template has holes based on the obtained coordinates, and if there are holes, obtains the positions of the holes on the periphery of the aluminum template, and then obtains the center position of the holes; the template recognition unit compares the generated template data with the template data stored in the template information database, and if the comparison error is within the set range, the model of the template is obtained, and finally, the identification code generation device is used to generate an identification code based on the recognition result of the aluminum template recognition device, and the generated identification code is printed by a coding device so as to be affixed to the corresponding aluminum template. First of all, the encoding method of this patent is very complex and cumbersome. At the same time, in order to realize its encoding, a large number of detection parts are required, which makes the device complex and the manufacturing cost expensive. Finally, it uses the method of printing the identification code and affixing it to the corresponding aluminum template. This method has the disadvantage that the identification code is easy to wear and fall off during use, and is easy to be corroded and invalid in the dust cleaning process, thereby causing management difficulties. Summary of the invention

[0010] The technical problem to be solved by the present invention is to provide a system and method for generating and identifying identification codes for aluminum alloy formworks for construction. The encoding method is simple and easy to implement, and different aluminum alloy formworks can be accurately and reliably identified. The structure is simple, the cost is reduced, and the management of aluminum alloy formworks is convenient.

[0011] The present invention is implemented as follows: a system for generating identification codes of aluminum alloy templates for construction, comprising a weighing device, an optical recognition subsystem and a coding processing unit; the optical recognition subsystem comprises an optical recognition target and an optical recognition module; the optical recognition module comprises a driving mechanism, a signal processing unit, and a light-emitting unit and a photosensitive unit arranged relatively; the photosensitive unit and the driving mechanism are respectively connected to the signal processing unit for communication; the signal processing unit and the weighing device are respectively connected to the coding processing unit for communication;

[0012] The weighing device measures the weight of the aluminum alloy template and sends the measured weight information to the encoding processing unit;

[0013] The optical recognition target is any side rib of the aluminum alloy formwork. A number of mounting bolt holes with equal spacing and equal diameter are provided on the side rib; identification holes are also provided between the mounting bolt holes, and the positions of the identification holes on the side ribs of different aluminum alloy formworks are not completely the same;

[0014] The driving mechanism drives the optical recognition module to move uniformly along the side rib;

[0015] The light-emitting unit generates a light source with stable intensity. During the process of the optical recognition module moving uniformly along the side rib, when passing through the mounting bolt hole or the identification hole, a light pulse signal is generated and received by the photosensitive unit;

[0016] The photosensitive unit measures the received light pulse signal and converts it into light pulse data to be sent to the signal processing unit;

[0017] The signal processing unit processes the light pulse data to generate an optical recognition code;

[0018] The coding processing unit generates the identification code of the final aluminum alloy formwork from the weight information and the optical recognition code.

[0019] Further, the side rib where the identification hole is located is the side rib with the longest side length of each aluminum alloy formwork.

[0020] Further, the aperture of the identification hole is smaller than the aperture of the mounting bolt hole.

[0021] The present invention also provides a method for generating an identification code of a building aluminum alloy formwork. The generation system as described above needs to be provided. The generation method includes the following steps:

[0022] Step 1: Before the initial use, first weigh the aluminum alloy formwork by a weighing device, and then the weighing device sends the measured weight information to the coding processing unit;

[0023] Step 2: Then drive the optical recognition module to scan the optical recognition target on the aluminum alloy formwork uniformly through the driving mechanism, so that the signal processing unit generates an optical recognition code and sends the optical recognition code to the coding processing unit;

[0024] Step 3: The coding processing unit generates the identification code of the final aluminum alloy formwork from the weight information and the corresponding optical recognition code of the aluminum alloy formwork and records it;

[0025] Step 4: Repeat Step 1 to Step 3 in sequence to generate the identification code of the next aluminum alloy formwork, and so on until the generation work of the identification codes of the whole set of aluminum alloy formworks is completed.

[0026] Further, in step 2, the optical recognition module is driven by a driving mechanism to scan the optical recognition target on the aluminum alloy template at a constant speed, so that the signal processing unit generates an optical recognition code specifically as follows: the optical recognition target is divided into several sections by the installation bolt holes arranged at equal intervals. When the optical recognition module scans the optical recognition target at a constant speed, the light emitted by the light-emitting unit only passes through one installation bolt hole or one identification hole at a time, thereby generating a light pulse signal; then the light pulse signal is received by the photosensitive unit, and the photosensitive unit converts the received light pulse signal into light pulse data and then sends it to the signal processing unit for processing. The signal processing unit forms a code according to the relative positions of the identification holes and the installation bolt holes in each section, and then concatenates the codes of each section to form the optical recognition code of a single aluminum alloy template.

[0027] Further, the signal processing unit forms a code according to the relative positions of the identification holes and the installation bolt holes in each section specifically as follows: the relative positions of the identification holes and the installation bolt holes in each section are numbered, and the same relative positions of the identification holes and the installation bolt holes in each section are numbered with the same number, and different ones are numbered with different numbers.

[0028] Further, in step 3, generating the identification code of the final aluminum alloy template specifically is: the coding processing unit concatenates the weight information of the aluminum alloy template and the corresponding optical recognition code.

[0029] Further, in step 3, generating the identification code of the final aluminum alloy template specifically is: the coding processing unit numbers the weight information of the aluminum alloy template, and different weight information is numbered with different numbers; then the numbers corresponding to the weight information and the optical recognition code corresponding to the aluminum alloy template are concatenated to form the identification code.

[0030] The present invention also provides an identification system for the identification code of a building aluminum alloy template, including the above-mentioned generation system, and also including an information-based aluminum formwork management system. The information-based aluminum formwork management system is communicatively connected to the coding processing unit of the generation system. The information-based aluminum formwork management system pre-stores the identification codes of aluminum alloy templates. The coding processing unit sends the generated identification codes to the information-based aluminum formwork management system, and the information-based aluminum formwork management system compares the received identification codes with the pre-stored identification codes, thereby identifying the received identification codes.

[0031] The present invention also provides an identification method for the identification code of a building aluminum alloy template. The identification method needs to provide the above-mentioned identification system; the identification method includes the following steps:

[0032] Step 11: Pre-enter and store the identification codes of each aluminum alloy template into the information-based aluminum formwork management system; communicatively connect the coding processing unit to the aluminum formwork management system;

[0033] Step 12: After the aluminum alloy formwork is cleaned by the dust cleaning production line, it is first weighed by a weighing device, and then the weighing device sends the measured weight information to the coding and processing unit;

[0034] Step 13: Then, the driving mechanism drives the optical recognition module to scan the optical recognition target on the aluminum alloy formwork at a constant speed. The light source emitted by the light emitting unit passes through only one installation bolt hole or one identification hole at a time, thereby generating a light pulse signal. Then, the light sensing unit receives the light pulse signal, converts the received light pulse signal into light pulse data, and sends it to the signal processing unit for processing. Thus, the signal processing unit generates an optical recognition code and sends the optical recognition code to the coding and processing unit;

[0035] Step 14: The coding and processing unit generates an identification code for the aluminum alloy formwork based on the weight information and the optical recognition code of the aluminum alloy formwork;

[0036] Step 15: The coding and processing unit sends the generated identification code to the information-based aluminum formwork management system. The aluminum formwork management system compares the received identification code with the pre-stored identification code, thereby identifying the received identification code.

[0037] The present invention has the following advantages:

[0038] (1) For the generation and identification system and method of the present invention, the side ribs of the aluminum alloy formwork are used as the optical recognition target, and identification holes are provided on the side ribs. Coding is performed based on the positions of the respective identification holes, so that the identification system can adapt to high-frequency impact, high temperature, and corrosion environments, and has good adaptability to the repair and maintenance of aluminum alloy formworks.

[0039] (2) For the generation and identification system and method of the present invention, combined coding using weight information and optical information can significantly increase the coding capacity and facilitate the management of aluminum alloy formworks.

[0040] (3) For the generation and identification system and method of the present invention, it has good fault tolerance and can adapt to surface wear and a certain degree of deformation of aluminum alloy formworks.

[0041] (4) For the generation and identification system and method of the present invention, there is no need to provide special components on the aluminum alloy formwork. The bolt installation holes are already existing in the aluminum alloy formwork in the prior art. Therefore, the present invention only needs simple mechanical processing to open the identification holes, which can be completed at low cost. Description of the Drawings

[0054] Please refer to Figures 1 to 10As shown in the figure, a generation system for the identification code of an aluminum alloy formwork for construction includes a weighing device 2, an optical recognition subsystem 3, and a coding processing unit 4; the optical recognition subsystem 3 includes an optical recognition object 11 and an optical recognition module; the optical recognition module includes a driving mechanism 33, a signal processing unit 34, and a light emitting unit 31 and a photosensitive unit 32 that are oppositely arranged; the photosensitive unit 32 and the driving mechanism 33 are respectively communicatively connected to the signal processing unit 34; the signal processing unit 34 and the weighing device 2 are respectively communicatively connected to the coding processing unit 4;

[0055] The weighing device 2 measures the weight of the aluminum alloy formwork 1 and sends the measured weight information to the coding processing unit 4;

[0056] The optical recognition object 11 is any side rib 11 of the aluminum alloy formwork 1. The side rib 11 is provided with a plurality of mounting bolt holes 111 that are equidistant and of the same diameter; identification holes 112 are also provided between the mounting bolt holes 111, and the positions of the identification holes 112 on the side ribs of different aluminum alloy formworks 1 are not completely the same;

[0057] Here, an explanation needs to be made for the fact that identification holes 112 are also provided between the mounting bolt holes 111: it includes that identification holes 112 are provided between every two adjacent mounting bolt holes 111, or not all adjacent mounting bolt holes 111 are provided with identification holes 112, and this can be set according to the number of aluminum alloy formworks 1; on the other hand, if identification holes 112 are provided between two adjacent mounting bolt holes 111, the number of identification holes 112 can also be the same, not completely the same, or different from each other.

[0058] The driving mechanism 33 drives the optical recognition module to move uniformly along the side rib 11;

[0059] The light emitting unit 31 generates a light source with stable intensity. During the process of the optical recognition module moving uniformly along the side rib 11, when passing through the mounting bolt hole 111 or the identification hole 112, a light pulse signal is generated and received by the photosensitive unit 32;

[0060] The photosensitive unit 32 measures the received light pulse signal and converts it into light pulse data and sends it to the signal processing unit 34;

[0061] The signal processing unit 34 processes the light pulse data to generate an optical recognition code;

[0062] The coding processing unit 4 generates the final identification code of the aluminum alloy formwork 1 based on the weight information and the optical recognition code.

[0063] In a specific embodiment, the side rib 11 where the identification hole 112 is located is the side rib 11 with the longest side length of each aluminum alloy formwork 1. Using the longest side rib 11 as the optical recognition target 11 enables a larger number of identification holes 112 to be opened thereon, thereby greatly increasing the capacity of the identification code and meeting the usage requirements of a larger number of aluminum alloy formworks 1.

[0064] In a specific implementation, in a preferred embodiment, the aperture of the identification hole 112 is smaller than the aperture of the installation bolt hole 111. The advantage is that the installation bolt hole 111 already exists in the existing aluminum alloy formwork 1 and is used for installing the formwork. The aperture of the identification hole 112 being smaller than the aperture of the installation bolt hole 111 can greatly reduce the impact on the strength of the aluminum alloy formwork 1 and ensure the usage strength of the aluminum alloy formwork 1. Although theoretically, the aperture of the identification hole 112 being larger than the aperture of the bolt installation hole is also possible, this will undoubtedly cause a greater impact on the strength of the aluminum alloy formwork 1. Similarly, the number of identification holes 112 opened between two adjacent installation bolt holes 111 cannot be increased indefinitely. Therefore, it is advisable to have 1 to 3 identification holes 112 opened between two adjacent installation bolt holes 111, and the aperture being smaller than the aperture of the bolt installation hole is optimal. When it is necessary to expand the capacity of the identification code, the above-mentioned other combination methods can be used for expansion.

[0065] In a specific embodiment, the optical recognition module further includes a fixing bracket 35; the fixing bracket 35 has an open receiving groove 351. During use, the side rib 11 is located in the open receiving groove 351; the output end of the driving mechanism 33 is connected to the fixing bracket 35; the light-emitting unit 31 and the photosensitive unit 32 are oppositely arranged on two side surfaces of the open receiving groove 351. The purpose of the driving mechanism 33 is to achieve uniform motion. As long as the light-emitting unit 31 can provide a light source with a stable intensity and the light can be received by the photosensitive unit 32 only through the bolt mounting holes or the identification holes 112, and for the signal processing unit 34 and the coding processing unit 4, there are already many mature technologies in the prior art, and any technology that can achieve these purposes can be used. For example, in a specific embodiment, the weighing device 2 is a weight sensor, the light-emitting unit 31 is an LED lamp bead, the photosensitive unit 32 adopts a CCD element or a CMOS device of a digital camera, the signal processing unit 34 is a single-chip microcomputer, the coding processing unit 4 is an encoder, the driving mechanism 33 includes a motor 331 and a ball screw nut pair. The screw rod 332 of the ball screw nut pair is connected to the output shaft of the motor 331, and the screw rod 332 is rotatably mounted on the support base 335 through a bearing 334. The nut 333 of the ball screw nut pair is fixedly connected to the fixing bracket 35. The motor 331 is communicatively connected to the signal processing unit 34. The signal processing unit 34 controls the motor 331 to rotate at a uniform speed, drives the screw rod 332 to rotate, and further drives the nut 333 to move linearly at a uniform speed, thereby driving the fixing bracket 35 to move at a uniform speed, and finally driving the light-emitting unit 31 and the photosensitive unit 32 on the fixing bracket 35 to move synchronously and uniformly. During use, it scans from one end of the optical recognition target 11 to the other end. In order to facilitate use, when generating the identification code in advance and identifying the identification code during the subsequent use process, the same scanning order can be set. For example, in the direction shown by Figure 6 From left to right or from right to left, which is convenient for workers to operate. The light-emitting unit 31 can be connected to the power supply alone or connected to the signal processing unit 34, and is uniformly controlled by the signal processing unit 34. After the signal processing unit 34 is powered on, the signal processing unit 34 supplies power. The area of the light emitted by the light-emitting unit 31 only needs to be greater than or equal to the area of the mounting bolt holes and the identification holes. There are no special requirements for the emitted light, as long as the light signal intensity is stable and can be received by the photosensitive unit 32. For example, it can emit ordinary light, infrared light, ultraviolet light, etc.

[0066] Before the first use, first use the identification system described in the present invention to generate identification codes for the entire set of aluminum alloy formworks 1. First, weigh the aluminum alloy formwork 1 through the weighing device 2, and then the weighing device 2 sends the measured weight information to the encoding processing unit 4; then drive the optical recognition module to scan the optical recognition target 11 on the aluminum alloy formwork 1 at a constant speed through the driving mechanism 33, so that the signal processing unit 34 generates an optical recognition code and sends the optical recognition code to the encoding processing unit 4; the encoding processing unit 4 generates the final identification code of the aluminum alloy formwork 1 according to the weight information and the optical recognition code of the aluminum alloy formwork 1 and records it; repeat steps 1 to 3 in sequence to generate the identification code of the next aluminum alloy formwork 1, and so on until the generation of the identification codes of the entire set of aluminum alloy formworks 1 is completed. In a specific embodiment, an existing information-based aluminum formwork management system 5 is used to manage the entire set of aluminum alloy formworks 1, and the encoding processing unit 4 is communicatively connected to the information-based aluminum formwork management system 5, and the identification codes of each aluminum alloy formwork 1 are pre-entered into the management system.

[0067] In the design of existing aluminum alloy formworks 1, for the consideration of reasonable formwork configuration, building aluminum alloy formworks 1 usually have significant differences in shape and weight. At the same time, the weight of a single aluminum alloy formwork is not too heavy, generally one person can pick it up and it is convenient to carry, such as about 10 Kg, and the heaviest generally does not exceed the weight that two people can lift, such as generally not exceeding 50 Kg. If it is heavier, it does not meet the actual production requirements. For example, taking the longest side as an example, the specification sizes of the aluminum alloy formwork 1 adopt a series of general standard sizes in the industry in the prior art, such as 0.6 m, 1.2 m, etc. The weight differences of aluminum alloy formworks 1 of different specifications are large. For example, the weights of these two aluminum alloy formworks 1 with different size specifications are about 5 Kg and 10 Kg respectively, and the weight difference is about: 5 Kg. Although the aluminum alloy formwork 1 may have problems such as wear and local deformation during on-site construction, its weight is basically unchanged after cleaning and refurbishment. Therefore, by combining the fact that the weight is basically unchanged after cleaning and refurbishment and the large difference in the weights of aluminum alloy formworks 1 of different weights, in actual use, a weight error range can be set for each weight series of aluminum alloy formworks 1. This error range can be designed to be relatively large, making the actual operability strong. Therefore, when re-identifying and warehousing after cleaning and refurbishment, the reliability of weight identification is improved. Therefore, the identification system described in the present invention uses the weighing device 2 to weigh a single aluminum alloy formwork 1. According to the weight measurement value, the encoding processing unit 4 can first classify the aluminum alloy formworks 1 according to their weights during prior encoding, and classify each aluminum alloy formwork 1 with the same weight into one category. When re-identifying and warehousing after cleaning and refurbishment, the category of the current aluminum alloy formwork 1 can be determined according to the pre-entered comparison information, which is convenient for management.

[0068] Meanwhile, the present invention adopts the method of opening identification holes 112 on one side rib 11 of the aluminum alloy formwork 1. The optical recognition area is divided into several sections by the installation bolt holes 111 arranged at equal intervals. Codes are formed according to the relative positions of the identification holes 112 in each section, and the codes of each section are connected in series to form the optical recognition code information of a single aluminum alloy formwork 1. In actual use, the positions of the identification holes 112 of each aluminum alloy formwork 1 are set to be not completely the same, which can ensure the uniqueness of the optical recognition codes of each aluminum alloy formwork 1. For example, in a specific implementation, in order to ensure the reliability of the code information, the last recognition code can also be used as a check bit. Finally, the present invention generates the final identification code of the aluminum alloy formwork 1 through the code processing unit 4 based on the weight information measured by the weighing device 2 and the optical recognition code recognized by the signal processing unit 34, so that each aluminum alloy formwork 1 has a unique identification code.

[0069] During use, after the optical recognition object 11 moves at a constant speed, when the optical recognition module passes through an area without the installation bolt holes 111 or the identification holes 112, the light emitted by the light emitting unit 31 is blocked by the optical recognition object 11 and cannot be received by the photosensitive unit 32; when passing through the installation bolt holes 111 or the identification holes 112, due to the existence of the installation bolt holes 111 and the identification holes in the optical recognition area, the light emitted by the light emitting unit 31 can pass through the installation bolt holes 111 or the identification holes 112 and be received by the photosensitive unit 32, enabling the photosensitive unit 32 to record a group of light intensity pulse signals. Since there are differences in the light transmission areas of the installation bolt holes 111 and the identification holes, the peak differences of the light pulse signals formed by the installation bolt holes 111 and the identification holes can be used for identification. Also, because the positions of the identification holes 112 on the side ribs 11 of different aluminum alloy formworks 1 are not completely the same, the entire group of connected light pulse signals obtained by the optical recognition module after scanning the optical recognition objects 11 of each aluminum alloy formwork 1 are also different, resulting in different optical recognition codes for each aluminum alloy formwork 1, ensuring uniqueness. The signal processing unit 34 processes the light pulse signals to correctly identify each coding information of the optical recognition object 11.

[0070] Since the present invention uses different hole diameters for the identification holes 112 and the bolt installation holes, there are differences in their light transmission areas, realizing different peak values of the light intensity pulse signals to generate the optical recognition code. Combined with the fact that the weight of the aluminum alloy formwork 1 remains basically unchanged after dust cleaning and refurbishment, the identification code of the aluminum alloy formwork 1 is generated. Its advantage is that after use, compared with the existing technologies such as using radio frequency chips, steel stamping, or bar code sticking, the influence of deformation, wear, and corrosion on the present invention is greatly reduced because the difference in the light transmission areas of the two types of holes, namely the bolt installation holes and the identification holes 112, remains basically unchanged after deformation, corrosion, and wear.

[0071] Thus, for the generation system of the present invention, one side rib 11 of the aluminum alloy formwork 1 is used as the optical recognition target 11, and identification holes 112 are provided on the side rib 11. Based on this as the coding basis, due to the different hole diameters and different light transmission areas of the identification holes 112 and the mounting bolt holes 111, the peak values of the light pulse signals are different. Coding is carried out through the positions of the respective identification holes 112, so that the recognition system can adapt to high-frequency impact, high temperature and corrosion environments, and has good adaptability to the maintenance of the aluminum alloy formwork 1.

[0072] The generation system of the present invention combines weight information and optical information for coding, which can significantly increase the coding capacity and facilitate the management of the aluminum alloy formwork 1.

[0073] The generation system of the present invention has good fault tolerance and can adapt to the surface wear and a certain degree of deformation of the aluminum alloy formwork 1.

[0074] The generation system of the present invention does not require special components to be provided on the aluminum alloy formwork 1. The bolt mounting holes are already existing in the aluminum alloy formwork 1 itself in the prior art. Therefore, the present invention only needs simple machining to open the identification holes 112, which can be completed at low cost.

[0075] When the generation system of the present invention is adopted, there are various ways to generate the identification code according to the combination of weight information and optical recognition coding. For example, different weights can be classified and represented by one or more English letters, such as A, B, C..., or AB, AC, AD... and so on. This greatly increases the coding capacity and can meet the usage requirements of a larger number of aluminum alloy formworks 1. Of course, weight can also be directly used as the code. Similarly, for each section of the optical recognition coding, first, there can be various positional relationships of the identification holes 112. For example, Figures 6 to 9Taking the embodiment as an example, identification holes 112 may or may not be provided between two adjacent mounting bolt holes 111 of one side rib 11, which can be set according to the quantity of the whole set of aluminum alloy formwork. Secondly, the number of identification holes 112 provided between two adjacent bolt mounting holes can also be one or more. Theoretically, the more the number, the more optical recognition codes are generated by combination, that is, the larger the capacity of the identification codes that can be achieved. Thirdly, the positional relationships between the identification holes 112 and the bolt mounting holes are different, which can generate larger combined codes and further expand the capacity. Moreover, if more than two identification holes 112 are provided between two adjacent bolt mounting holes, the different positional relationships between the identification holes 112 there can generate different combinations, which also expands the capacity of the codes and has a wider range of applications. Finally, the diameters of the identification holes 112 can also be not completely the same, so the peak values of the generated optical pulse signals are different, and the capacity of the combined identification codes can be greatly increased. In a specific implementation, taking Figure 6 as an example, the codes 1, 2,... can be represented by numbers, for example, 1, 2,... or 01, 02,...; different codes are represented by different numbers. For example, for the convenience of manufacturing, several kinds of hole spacings can be set corresponding to different digital codes, so that it is convenient to open the identification holes 112. Finally, the optical recognition code is directly formed by connecting the codes of each section in series, such as 123..., and combined with the code of the weight information and directly connected in series to generate the final identification code, such as A123 or AB112, etc.

[0076] The present invention also provides a method for generating an identification code of an aluminum alloy formwork for construction. The generation system needs to be provided, and the generation method includes the following steps:

[0077] Step 1: Before the first use, first weigh the aluminum alloy formwork 1 through the weighing device 2, and then the weighing device 2 sends the measured weight information to the coding processing unit 4;

[0078] Step 2: Then drive the optical recognition module to scan the optical recognition target 11 on the aluminum alloy formwork 1 at a constant speed through the driving mechanism 33, so that the signal processing unit 34 generates an optical recognition code and sends the optical recognition code to the coding processing unit 4;

[0079] Step 3: The coding processing unit 4 generates the final identification code of the aluminum alloy formwork 1 according to the weight information of the aluminum alloy formwork 1 and the corresponding optical recognition code and records it;

[0080] Step 4: Sequentially repeat Steps 1 to 3 to generate the identification code of the next aluminum alloy formwork 1, and so on until the generation work of the identification codes of the whole set of aluminum alloy formwork is completed.

[0081] In a specific implementation, a preferred embodiment is as follows: In step 2, the optical recognition module is driven by the driving mechanism 33 to scan the optical recognition target 11 on the aluminum alloy template 1 at a constant speed, and the optical recognition code is generated by the signal processing unit 34 specifically as follows: The optical recognition target 11 is divided into several sections by the equally spaced installation bolt holes 111. When the optical recognition module scans the optical recognition target 11 at a constant speed, the light emitted by the light emitting unit 31 passes through only one installation bolt hole 111 or one identification hole 112 at a time, thereby generating a light pulse signal. Since the apertures of the bolt installation holes or the identification holes 112 are different, the light transmission areas of the two are different, and thus the peak values of the generated light pulse signals are different. Therefore, after being received by the photosensitive unit 32, the light pulse signals generated by the light source passing through the two can be recognized; then the light pulse signal is received by the photosensitive unit 32, and the photosensitive unit 32 converts the received light pulse signal into light pulse data and then sends it to the signal processing unit 34 for processing. The signal processing unit 34 forms a code according to the relative positions of the identification holes 112 and the installation bolt holes 111 in each section, and then concatenates the codes of each section to form the optical recognition code of a single aluminum alloy template 1.

[0082] In a specific implementation, a preferred embodiment is as follows: The signal processing unit 34 forms a code according to the relative positions of the identification holes 112 and the installation bolt holes 111 in each section specifically as follows: The relative positions of the identification holes 112 and the installation bolt holes 111 in each section are numbered, and the same numbers are used for the same relative positions of the identification holes 112 and the installation bolt holes 111 in each section, and different numbers are used for different ones.

[0083] In a specific implementation, a preferred embodiment is as follows: In step 3, the generation of the identification code of the aluminum alloy template 1 is specifically as follows: The coding processing unit 4 concatenates the weight information of the aluminum alloy template 1 and the corresponding optical recognition code.

[0084] In a specific implementation, a preferred embodiment is as follows: In step 3, the generation of the identification code of the aluminum alloy template 1 is specifically as follows: The coding processing unit 4 numbers the weight information of the aluminum alloy template 1, and different weight information uses different numbers; then the numbers corresponding to the weight information and the optical recognition code corresponding to the aluminum alloy template 1 are concatenated to form the identification code.

[0085] The present invention also provides an identification system for the identification codes of building aluminum alloy formworks, which includes the aforementioned generation system and also includes an information-based aluminum formwork management system 5. The information-based aluminum formwork management system 5 is communicatively connected to the coding processing unit 4 of the generation system. The information-based aluminum formwork management system 5 pre-stores the identification codes of the aluminum alloy formworks 1. The coding processing unit 4 sends the generated identification codes to the information-based aluminum formwork management system 5, and the information-based aluminum formwork management system compares the received identification codes with the pre-stored identification codes, thereby identifying the received identification codes.

[0086] In a specific embodiment, the information-based aluminum formwork management system 5 is installed on a computer 6. The coding processing unit 4 is connected to the computer 6 through a data cable. The identification codes of the entire set of aluminum alloy formworks are pre-stored in the information-based aluminum formwork management system 5. When the aluminum alloy formwork 1 is used and then undergoes dust cleaning and refurbishment and is re-stored in the warehouse, it is scanned by the identification code generation system in the aforementioned identification system, and then the obtained identification codes are transmitted to the information-based aluminum formwork management system 5 in the computer 6 for comparison, thereby performing identification. If the scanned identification codes are the same as the pre-stored identification codes, it indicates that the re-storage of this aluminum alloy formwork 1 is successful. When they are different, it means that this aluminum alloy formwork 1 does not belong to this set of aluminum alloy formworks. The identification code can be queried in the entire information-based aluminum alloy formwork to see which set of aluminum alloy formworks it belongs to and needs to be re-classified and stored. When the entire set of aluminum alloy formworks after dust cleaning and refurbishment is completely stored in the warehouse, it can be directly viewed in the information-based aluminum formwork management system 5 to see which ones of this set of aluminum alloy formworks are missing or scrapped. In the entire identification process, there will be no situation where the radio frequency chips, barcodes, or steel stamping codes used in the prior art are damaged or corroded, resulting in inability to identify, thus leading to inability to distinguish whether the formwork belongs to this set of aluminum alloy formworks and which formwork in the pre-stored ones, resulting in confusion in inventory and property management. By using the identification system of the present invention, the recycling situation of the entire set of aluminum alloy formworks can be clearly tracked and managed.

[0087] The information-based aluminum formwork management system 5 is a prior art, and an existing inventory management system such as ERP can be directly adopted.

[0088] The present invention also provides an identification method for the identification codes of building aluminum alloy formworks. The identification method requires the aforementioned identification system; the identification method includes the following steps:

[0089] Step 11: Pre-enter and store the identification codes of each aluminum alloy formwork 1 into the information-based aluminum formwork management system 5; communicatively connect the coding processing unit 4 to the aluminum formwork management system;

[0090] Step 12: After the aluminum alloy formwork 1 is cleaned by the dust cleaning production line, it is first weighed by the weighing device 2, and then the weighing device 2 sends the measured weight information to the encoding and processing unit 4;

[0091] Step 13: Then, the driving mechanism 33 drives the optical recognition module to scan the optical recognition target 11 on the aluminum alloy formwork 1 at a constant speed. The light source emitted by the light emitting unit 31 passes through only one installation bolt hole 111 or one identification hole 112 at a time, thereby generating a light pulse signal. Since the apertures of the bolt installation hole or the identification hole 112 are different, the light transmission areas of the two are different, and thus the peak values of the generated light pulse signals are different. Therefore, after being received by the photosensitive unit 32, the light pulse signals generated after the light source passes through the two can be recognized; then the photosensitive unit 32 receives the light pulse signal, and the photosensitive unit 32 converts the received light pulse signal into light pulse data and then sends it to the signal processing unit 34 for processing. Thus, the signal processing unit 34 generates an optical recognition code and sends the optical recognition code to the encoding and processing unit 4;

[0092] Step 14: The encoding and processing unit 4 generates an identification code for the aluminum alloy formwork 1 based on the weight information and the optical recognition code of the aluminum alloy formwork 1;

[0093] Step 15: The encoding and processing unit 4 sends the generated identification code to the information-based aluminum formwork management system 5. The aluminum formwork management system compares the received identification code with the pre-stored identification code, thereby identifying the received identification code.

[0094] In the generation system, generation method, recognition system, and recognition method of the present invention, the side rib 11 of the aluminum alloy formwork 1 is used as the optical recognition target 11, and the identification hole 112 is provided on the side rib 11. By using the different apertures of the identification hole 112 and the installation bolt hole 111, their light transmission areas are different, and the peak values of their light pulse signals are different. Thus, coding can be performed through the positions of the respective identification holes 112, so that in the subsequent use process, it can adapt to high-frequency impact, high temperature, and corrosion environments. The identification holes 112 will not fall off, have little deformation influence, are not easily worn or corroded, and have good adaptability to the repair and maintenance of the aluminum alloy formwork 1.

[0095] Moreover, in the generation system, generation method, recognition system, and recognition method of the present invention, combined coding using weight information and optical information can significantly increase the coding capacity and facilitate the management of the aluminum alloy formwork 1.

[0096] At the same time, in the generation system, generation method, recognition system, and recognition method of the present invention, by using the opened identification holes 112 as the basis for coding, it has good fault tolerance and can adapt to the surface wear and a certain degree of deformation of the aluminum alloy formwork 1.

[0097] Finally, by adopting the generation system, generation method, recognition system, and recognition method of the present invention, there is no need to set up dedicated components on the aluminum alloy formwork 1. The bolt mounting holes are already existing in the aluminum alloy formwork 1 in the prior art. Therefore, the present invention only needs simple machining to open the identification holes 112, which can be completed at low cost. Compared with the method of setting radio frequency chips or sticking barcodes in the prior art, it is safer, more reliable, and has lower costs.

[0098] Ultimately, by using the generation system, generation method, recognition system, and recognition method of the present invention to manage the aluminum alloy formwork 1, the management can be made more convenient. During the recycling process, the identification code is safer and more reliable. Compared with the prior art, it will not cause the aluminum alloy formwork 1 to be unrecognizable due to the damage of the radio frequency chip or the wear, shedding, or corrosion of the barcode, resulting in management chaos. By adopting the generation system, generation method, recognition system, and recognition method of the present invention, these adverse effects are greatly reduced.

[0099] Although the specific embodiments of the present invention have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered by the scope protected by the claims of the present invention.
