Abstract
Description
Technical Field
[0001] This utility model relates to the field of visual recognition technology, specifically to an automatic identification system for steel coil numbers when a vehicle enters a warehouse. Background Technology
[0002] In the steel metallurgical industry, leveling units in hot rolling production are used to level hot-rolled steel coils stored in the hot-rolled product warehouse after hot rolling, in order to improve the shape and surface quality of the hot-rolled coil products. Currently, the ID verification of incoming steel coils in the hot-rolled product warehouse is done manually. The manual operation method is as follows: ① Recording steel coil IDs: The steel coil IDs provided by the manufacturer or upstream process are entered into the warehouse management system to complete the recording of the steel coil IDs to be stored. ② On-site verification: First, the warehouse entrance area is sealed off, and all steel coil IDs to be stored are manually copied and verified against the warehouse management system to determine if the ID numbers match. If they match, the next step is performed; otherwise, the material is returned or manually marked and modified. The manual verification method for steel coil IDs results in a large amount of manual work, low production efficiency, and the risk of human error, leading to the risk of mixed steel production. Therefore, how to accurately and efficiently complete the identification and verification of incoming steel coil IDs is very important for improving production efficiency and saving labor and production costs. Utility Model Content
[0003] The purpose of this utility model is to disclose an automatic identification system for steel coil numbers when a vehicle enters the warehouse, so as to improve the efficiency of steel coil number identification.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An automatic identification system for steel coil numbers entering a warehouse via a cross-pass vehicle includes an industrial control computer. The industrial control computer is connected to a photoelectric position sensor and an industrial camera located next to the cross-pass vehicle's entry station. A laser rangefinder is also installed at the front end of the cross-pass vehicle's entry station. The laser rangefinder is connected to the industrial control computer, which is also connected to a warehouse management system.
[0006] Furthermore, multiple photoelectric position sensors are provided, and each corresponds to a position of a steel coil on the crossing vehicle.
[0007] Furthermore, the industrial camera employs multiple CCD cameras positioned vertically to facilitate comprehensive scanning of the steel coil and quickly capture its ID number.
[0008] Compared with the prior art, the present invention has the following beneficial effects:
[0009] This system overcomes the challenges of the complex environment in steel production (high temperatures, dust, oil, etc.) while ensuring equipment accuracy and durability. By automating coil number identification, it reduces manual intervention and data entry time, improving work efficiency, especially in large-scale production where it accelerates coil turnover and management. Automatic coil number identification effectively reduces input errors that can occur with manual entry, improving data accuracy. Furthermore, it records the production, transportation, and inventory status of coils in real time, helping companies better monitor and manage inventory and optimize resource allocation.

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.
[0011] In the diagram: 1-Industrial control computer, 2-Photoelectric position sensor, 3-Industrial camera, 4-Laser rangefinder. Detailed Implementation
[0012] The present invention will be further explained below with reference to the accompanying drawings.
[0013] like Figure 1 As shown, an automatic identification system for steel coil numbers for cross-passage vehicle entry into the warehouse includes an industrial control computer 1, which is connected to a photoelectric position sensor 2 and an industrial camera 3 located next to the cross-passage vehicle entry station. A laser rangefinder 4 is also installed at the front end of the cross-passage vehicle entry station, which is connected to the industrial control computer 1. The industrial control computer 1 is also connected to the warehouse management system.
[0014] Multiple photoelectric position sensors 2 are installed, each corresponding to a position of a steel coil on the crossover vehicle. They are used in conjunction with a laser rangefinder 4 to determine whether the crossover vehicle is parked in place.
[0015] The industrial camera 3 uses multiple CCD cameras arranged vertically to facilitate comprehensive scanning of the steel coil and quickly capture the steel coil ID number.
[0016] The working process of this utility model is as follows:
[0017] When the transfer vehicle carrying hot-rolled raw material coils arrives at the warehousing station (up to four coils, with coil numbers painted on the end face), photoelectric position sensor 2 and laser rangefinder 4 simultaneously detect the parking position and forward direction of the transfer vehicle to ensure that it is parked in place. The arrival signal is uploaded to industrial control computer 1, which calls industrial camera 3 to capture an image of the end face of the coil and sends it back to industrial control computer 1 for processing and identification of the coil number. The identification result is then verified against the coil number in the warehouse management system. If there is a discrepancy, an alarm is issued to remind manual verification and handling to prevent incorrect material loading. At the same time, the alarm information is sent back to the warehouse management system for note-taking, guiding the transfer vehicle to stack the coils with mismatched numbers in the temporary storage area of the warehouse for subsequent processing.
[0018] The automatic steel coil number identification system disclosed in this utility model saves labor costs, improves work efficiency, and avoids the risk of production accidents caused by human error and mixed steel. It has positive significance for the efficient operation of the hot rolling production leveling unit production line.
