[0014] Furthermore, the current status includes: idle, loaded, and faulty.

[0015] Furthermore, the step 4) is specifically as follows: when the C-hook with a predetermined number is installed on the steel billet, the space after the C-hook number corresponding to the current status column in the array is changed to "there is material", and the space after the C-hook number corresponding to the steel billet number column in the array is filled with the unique number of the steel billet.

[0016] Furthermore, the method also includes a step of displaying the position, current status and billet number of each C-hook in real time in the secondary system.

[0022] Figure 1 This is the system architecture of the present invention.

[0023] Figure 2 The figure is a flow chart of the C-hook mark and the steel billet matching tracking algorithm of the present invention. DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 As shown, the present invention mainly consists of the following parts:

[0029] 1. On-site equipment: including heating furnace, roughing mill, finishing mill, laying head, coiling machine, P&F line (Power & Free Conveyer), packaging and labeling equipment, etc.

[0030] 2. Automatic billet number generation system: an algorithm program that automatically generates billet numbers. The batch number of the billet is automatically generated according to the set rules for subsequent tracking and correspondence with the secondary system.

[0031] 3. Billet tracking system: automatically bind the generated billet number to the billet and track it throughout the production process.

[0032] 4. C-type hook number and billet matching tracking system: When the billet enters the P&F line, the C-type hook number is bound to the billet and tracked until the billet leaves the P&F line.

[0033] The core of the invention is two parts: an automatic generation algorithm of a steel billet number and a matching tracking algorithm of a C-type hook number and a steel billet.

[0034] Automatic generation algorithm for billet number:

[0035] The steel billets are put into the heating furnace in batches from the trolley frame for heating, and then sent to the roller table one by one by the heating furnace. The heating furnace is responsible for tracking the steel billets in the heating furnace. The steel billet number tracking responsible for the present invention starts from the time when the steel billets come out of the heating furnace.

[0036] First, the billet number is a 13-digit string. For example, 02202408100001, from left to right, 1-2 is the workshop number (the example is workshop 02), 3-6 is the year (the example is 2024), 7-10 is the month date (the example is August 10), and 11-14 is the batch number of the day. When midnight arrives every day, 1-10 digits are generated according to the date of the day, and 11-14 digits start with 0001 by default, and then accumulate.

[0037] The automatic generation algorithm of billet number mainly determines when to accumulate 11-14 digits. If there is an unexpected event such as flying steel during the production process, the current billet can be marked as scrap steel on the first-level screen, and the current serial number will be marked as scrap steel and no longer used, and subsequent billets will continue to be generated according to the original rules.

[0038] C-type hook and billet matching tracking algorithm:

[0039] After the high-speed wire production line is built, the number of C-hooks on the P&F line is determined, and the numbering is also determined. Assuming there are 30, they are numbered 1-30. The first-level PLC will mark the location of each numbered C-hook in advance, and then dynamically track and adjust it as the system runs normally. The first-level PLC is designed with a special array to maintain the location of the C-hooks and the corresponding billet number.

[0040] In addition, the algorithm has a built-in verification function. Separate signal detection devices are installed on the 10th, 20th, 30th, and so on C-type hooks on the P&F line. One signal detection device is added to every 10 C-type hooks. Whenever a C-type hook equipped with a signal detection device passes a specified position, the positions of all C-type hooks will be verified. If there is a difference, corresponding adjustments will be made. For example, when the 10th C-type hook reaches the verification point, it means that there are 9 C-type hooks in front. If only 8 or 11 are recorded at this time, it means that the record is wrong. At this time, all previous records are refreshed, and alarms are issued and recorded through the operation interface.

[0041] Whenever a rolled steel billet is hung on a C-hook, the billet number will be bound to the C-hook until the C-hook runs to the packaging area to unload the coil, at which time the billet number will be untied from the C-hook.

[0042] During the entire tracking process, the secondary system can obtain the number and location of a certain billet at any time.

[0043] The present application embodiment discloses a method for tracking hook numbers of a high-speed wire suspension conveyor, comprising the following steps:

[0044] a) The algorithm starts. First, the steel billet coming out of the heating furnace is numbered 02202408100001, and all C-hooks are set to idle state.

[0045] b) The primary PLC system (including roughing mill, finishing mill, laying mill, etc.) monitors the position of the steel billet at all times and transmits the corresponding position information to the coiler PLC. The coiler PLC receives the signal from the upper PLC and detects the steel billet with its own steel billet detection device. After detecting the steel billet, the corresponding number is bound to the steel billet.

[0046] c) After the coiler has finished coiling the billet, it waits for the arrival of the C-hook. Assuming that the C-hook numbered 5 arrives at this time, the coiler will install the billet on the C-hook and send the numbering information (02202408100001) to the P&F line PLC. After receiving the billet numbering signal, the P&F line PLC will bind it to the No. 5 C-hook and set the No. 5 C-hook to the billet status. It will also display the billet number and other related information on the corresponding first-level screen at the location of the No. 5 C-hook.

[0047] d) Schematic diagram of the C-hook status and number binding array in PLC:

[0048]

[0049]

[0050] e) A normal ending process:

[0051] When the No. 5 C-type hook runs to the packaging and unloading stage after a period of time, the P&F line PLC will reset the No. 5 C-type hook to the idle state and continue the next cycle.

[0052] f) An abnormal termination process:

[0053] Assuming that a steel billet with a certain number (taking number 02202408100010 as an example) has a flying steel failure during the production process, at this time, the operator is required to dispose of the steel billet with this number as scrap steel on the first-level screen, and the subsequent information of the steel billets with this number will be skipped, which will not affect the subsequent production of steel billets.

[0054] g)Steel billet tracking:

[0055] When the billet is on the roller table of the heating furnace, the corresponding billet number will be generated on the first-level screen, and the billet number will follow the billet until the unloading and packaging are completed. The first-level screen of the P&F line will display the location of each coded C-hook and the status of the C-hook (including idle, loaded, faulty, etc.) in real time. The C-hook with loaded material will display the billet number, and the second-level system can read these billet information in real time.

[0056] h) The billet number will be automatically reset in the early morning of the next day, that is, it will become 02202408110001.
