Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent control of non-ferrous metal processing equipment, and specifically discloses an intelligent logistics equipment scheduling control system and method for heat treatment processes in a dark factory. Background Art

[0002] Dark Factory is a literal translation of "Dark Factory", that is, a smart factory. It mainly refers to the industrial production process where all processing, transportation, and inspection processes from raw materials to final products are completed in a factory area without any workers. Industrial robots and other industrial equipment are used to replace factory labor, enabling operation with the lights off, hence the name Dark Factory. Dark Factory is an important concept in the current industrial development of our country. At present, various types of industrial production enterprises, especially those in the fields of electronics, chemical industry, metal manufacturing, etc., have successively started practical explorations related to Dark Factories.

[0003] Aluminum sheet and strip factories in Western developed countries have accumulated rich experience in intelligent control aspects such as process software packages, ERP (Enterprise Information Management System), MES (Mechanical Manufacturing Management System), WMS (Warehouse Management System), and WCS (Warehouse Control System). Especially in recent years, the development of big data, 5G, and AI technologies has accelerated the intelligent manufacturing development of Western aluminum sheet and strip and even the aluminum processing industry. Currently, most domestic aluminum sheet and strip production enterprises do not manage materials informatization, and the traditional manual management mode still occupies the main market position. Only a few large enterprises have introduced intelligent warehouses, ERP, MES and other systems. Only a very small number of large enterprises manage finished products and on-site materials or are only limited to managing the finished product warehouse. These systems are still not popular in small and medium-sized enterprises, and the applications of WMS and WCS are very few.

[0004] For some medium and large-sized aluminum processing enterprises, there are many processes, and correspondingly, there are many raw material and finished product warehouses. Some enterprises do not code the storage locations of the warehouses, making management more difficult. If you want to manage information such as the warehouses and material flow of the entire factory using traditional methods, it is labor-intensive, resource-consuming, and time-consuming. With the rapid development of the domestic aluminum processing industry, enterprises urgently need to use new-generation information technologies such as modern logistics technologies, intelligent transportation equipment, and mobile Internet to achieve the rapid flow of internal materials of the enterprise, and use intelligent equipment for transportation to reduce labor costs and improve the safety of the logistics transportation process. Summary of the Invention

[0005] In order to solve the problems in the background art, the present invention discloses an intelligent logistics equipment scheduling control system and method for heat treatment processes in a dark factory, which interconnects the data of intelligent logistics scheduling, high-bay warehouses, AGVs, intelligent overhead cranes, industrial furnaces, etc., realizes the automatic flow of materials and intelligent annealing in heat treatment processes, and promotes the intelligent and digital transformation and upgrading of the non-ferrous metal processing industry in China.

[0035] To better understand the present invention, the content of the present invention will be further clearly elaborated below in combination with embodiments. However, the protected content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. Here, it should be noted that the intelligent logistics equipment scheduling control system and method for the heat treatment process in a black light factory are the innovative points of the present invention, and the material car and the overhead crane are not the innovative points of the present invention. Therefore, the structures of the material car and the overhead crane will not be described in detail.

[0036] Combined with the attached Figures 1-4 , the intelligent logistics equipment scheduling control system for the heat treatment process in the black light factory of the present invention is elaborated in detail. The control system adopts a multi-level industrial Ethernet interactive device structure, including an MES system, a WMS and scheduling system, and an automated central control system that are communicatively connected. It uses a 100M wired and wireless network to connect the WMS and scheduling system, the annealing furnace process equipment system, the elevated dock logistics system, and the intelligent overhead crane system, supports the Siemens industrial communication protocol, and has the characteristics of safety, stability, and reliability.

[0037] The MES system is used to formulate task instructions according to the work plan;

[0038] The scheduling control system of the present invention takes the WMS and scheduling system as the organizational core and the automated central control system as the control center. The WMS and scheduling system is connected to the MES system upwards, receives task instructions from the MES system, decomposes the received task instructions, and issues the decomposed instructions to the automated central control system. At the same time, it receives feedback information such as the execution status and warehouse location information from the automated central control system.

[0039] The automated central control system respectively issues automated control instructions to the elevated dock logistics system, the material car control system, the intelligent overhead crane system, and the annealing furnace, cooling chamber, and fan room control systems according to the received decomposed instructions, realizes the intelligent flow of the coil and automated annealing. The control terminals of the elevated dock logistics system, the material car control system, the intelligent overhead crane system, and the annealing furnace, cooling chamber, and fan room respectively feedback their execution status, status information, and / or warehouse location information to the automated central control system. The automated central control system returns the received execution status, status information, and warehouse location information to the MES system through the WMS and scheduling system.

[0040] The automated central control system is the bridge and link between the WMS and scheduling system and lower-level systems such as the annealing furnace process equipment system and the intelligent traveling crane system. It receives task instructions from the WMS and scheduling system upward and simultaneously feeds back execution information. After processing and decomposing the task instructions from the WMS and scheduling system, it issues task instructions downward, and processes the execution and status information from systems such as the intelligent traveling crane system and the annealing furnace process equipment system and uploads it to the WMS and scheduling system. Its role is crucial.

[0041] Data interaction and transmission among MES, WMS and scheduling system, automated central control system, intelligent traveling crane control system, skip control system, and control systems of annealing furnace, cooling chamber and fan room are as Figure 3 shown in the data information interaction and transmission. The system has rich communication interfaces, supporting multiple communication protocols, such as: OPC_UA, TCP / IP, UDP, MODBUS TCP, etc. The rich communication interfaces effectively support the seamless access of third-party systems, laying a good network foundation for the future expansion of the project;

[0042] The elevated dock logistics system is used to real-time regulate the storage location information of materials in the elevated dock and the import warehouse of materials in the elevated dock;

[0043] The intelligent traveling crane system is used to transport coil materials back and forth between the elevated dock or AGV material level and the designated material platform and rack or the designated material platform and rack. The intelligent traveling crane system realizes the driverless, precise positioning, and automatic lifting and lowering of the traveling crane through functions such as automatic control and drive control, automatic positioning, anti-collision, spreader control, and anti-sway control;

[0044] The skip control system is used to transfer coil materials back and forth between the designated material platform and rack and the annealing furnace. The skip control system performs automatic control of the skip according to the scheduling instructions of the superior system and monitors the fault and status information. The functions of the skip control system include: 1) Intelligent real-time perception of skip position: ① Intelligent real-time perception of the horizontal movement real-time position of trolley A, ② Automatic perception of trolley A's return to position, ③ Automatic perception of trolley A's horizontal movement in place; 2) Automatic / semi-automatic / manual operation mode switching of the skip; 3) Real-time safety protection of the skip: ① Safety scanning during skip operation; ② Skip operation warning, system Ethernet communication;

[0045] The annealing furnace automation control system is used for automatic control of furnace door opening and closing, annealing process, and monitoring of annealing furnace faults and / or status information. The annealing furnace control system can realize automatic control of the furnace door, automation of the annealing process, and monitoring of faults and status information. The functions of the annealing furnace control system include: 1) Automatic / semi-automatic / manual operation mode switching of the furnace door; 2) Automatic / manual mode switching under the annealing process; 3) Safety protection: ① Emergency operation for furnace door lifting and lowering; ② Maintenance mechanical protection safety device; 4) Ethernet communication;

[0046] Cooling chamber and fan room control system, used for the automatic control of the chamber door of the cooling chamber, automatically measuring the temperature of the material after cooling and annealing, monitoring the faults and status information of the cooling chamber and the fan room, and the automatic transfer request of the cooled material. The functions of the cooling chamber and fan room control system are as follows: 1) Switching between automatic / semi-automatic / manual operation modes of the chamber door; 2) Safety protection: ① Emergency operation for the lifting of the chamber door; ② Maintenance mechanical protection safety device; 3) Automation transformation of the electric control cabinets of the cooling chamber control system and the fan control system; 4) Real-time automatic monitoring of the temperature of the coil; 5) Real-time automatic measurement and remote monitoring of the fan speed;

[0047] Using the intelligent logistics equipment scheduling control system for the heat treatment process in the black light factory of the present invention, the automatic transfer process of the coil from the high-bay warehouse, annealing in the annealing furnace, cooling, and storage in the high-bay warehouse is realized. Real-time information interaction is carried out with the existing MES system, a series of operations are carried out according to the tasks of the MES system, and the execution results are fed back to the MES system; and the materials from the high-bay warehouse dock or the AGV stock level to the annealing furnace workshop are managed, and the status and location information of the coil are grasped in real time.

[0048] Furthermore, for the intelligent logistics equipment scheduling control system for the heat treatment process in the black light factory, the automated central control system provides multiple control modes for the equipment of the high-bay dock logistics system, the material car control system, the intelligent crane system, and the annealing furnace, cooling chamber and fan room control systems, making production safer and more reliable, namely manual control, semi-automatic control, full-automatic control, maintenance and emergency stop modes;

[0049] Full-automatic control: In the full-automatic control mode, the control commands of the automated central control system for the transportation, annealing, and cooling equipment come from the upper-level system. The production task is issued by the MES system. After the task is processed by the WMS and the scheduling system, multiple scheduling and process instructions are issued to the automated central control system. The automated central control system decomposes the scheduling and process instructions, and issues matching production scheduling and process instructions to the centralized control system for the annealing process equipment. After receiving the instructions, the centralized control system realizes the automatic control of equipment such as the material car, annealing furnace, cooling chamber, and fan room. The main operations reflected in the actuators include the start / stop, acceleration / deceleration of the motor, and the start / stop of the power devices, etc. Finally, the full process control of the transfer, annealing, and cooling of the coil is realized;

[0050] Semi-automatic control: In the semi-automatic control mode, the automated central control system refuses to receive the control commands from the upper-level system. All task instructions are all automatically issued by people according to the technological process in parts. The automated central control system receives the automatic instructions issued manually and directly issues them to the actuators of the corresponding equipment. After the equipment executes the instructions, the execution results are fed back and displayed on the L2-level system. According to the feedback prompt, people continue to issue the next instruction. All instructions are issued manually and the equipment execution is completed, and the processes such as the transfer, annealing, and cooling of the coil between the annealing process equipment are completed;

[0051] Manual control: In the manual control mode, the automated central control system does not receive any automatic instructions. All equipment related to the annealing process, such as the annealing furnace, cooling chamber, fan room, and charging car, need to be manually operated on-site.

[0052] Maintenance: The maintenance work mode is mainly for the maintenance or repair of a certain process equipment when it malfunctions. In this mode, the hardware emergency stop of this equipment needs to be pressed in cooperation. The L2-level system cuts off the task source from the source and issues a warning. The equipment no longer receives any production instructions. After the maintenance or repair is completed, switch back to other working modes.

[0053] Emergency stop: The emergency stop mode is an operation function set for emergencies. There are on-site and remote emergency stop buttons, which have the highest priority. Regardless of the fully automatic, semi-automatic, or manual control mode, the equipment in operation will stop immediately when the emergency stop button is pressed.

[0054] The intelligent logistics equipment scheduling control system for the heat treatment process in the so-called "dark factory" further includes a natural cooling rack system. The natural cooling rack system includes several storage positions and a monitoring module for automatically monitoring the temperature of the annealed coil placed on the storage position and the storage position rack. The functions of the monitoring module of the natural cooling rack system are as follows: 1) Automatic monitoring of the AGV storage position; 2) Automatic monitoring of the storage position of the natural cooling rack; 3) Automatic monitoring of the temperature of the coil on the natural cooling rack.

[0055] The working process of realizing the intelligent logistics equipment scheduling control for the heat treatment process in the dark factory by using the above-mentioned intelligent logistics equipment scheduling control system for the heat treatment process in the dark factory is as follows:

[0056] The MES system formulates task instructions according to the work plan and issues the task instructions to the WMS and the scheduling system;

[0057] The coil to be annealed is transported to the elevated dock through the high-rise warehouse and the transfer car according to the MES instruction, and the necessary information such as the coil information and coordinate information is issued to the WMS and the scheduling system. After the WMS and the scheduling system analyze the task, they issue instructions to the automated central control system;

[0058] The automated central control system distributes the transportation tasks and the annealing process-related information to the intelligent crane system, the charging car control system, and the annealing furnace control system according to the decomposed instructions;

[0059] The intelligent driving system controls the driving to lift the material coil on the elevated wharf or AGV material position to the designated material platform rack according to the received transportation task information. The detailed process of the driving work is as follows: the intelligent driving system instructs the driving to automatically run according to the material coil coordinate information and stops running after reaching the destination coordinate mark, and the hoisting device starts to automatically descend. When it descends to the set height according to the material coil coordinate information, the hoisting device automatically stops descending, and the clamp starts to close. After closing in place and detecting that the material coil is successfully lifted, the hoisting device automatically rises to the original position, and the driving starts to run automatically, lifting the material coil to the designated material rack saddle of the 1# or 2# material platform (hereinafter referred to as the material platform). After reaching the designated coordinate, the driving trolley B and the trolley B stop running, and the hoisting device starts to automatically descend. After descending to the set height coordinate and detecting that the material coil is successfully placed, the hoisting device starts to automatically open. After the hoisting device is opened in place, it starts to automatically rise, and the lifting of this material coil is completed. Then, according to the lifting quantity required by the automated central control system, the remaining material coils are sequentially lifted to the corresponding saddles of the material rack;

[0060] The information of the completion of the lifting of the material coil is fed back to the automated central control system, and the automated central control system sends the confirmation signal and operation instruction of the completion of the lifting of the material coil to the material trolley control system. The material trolley control system controls the material trolley to transport the material rack with the material coil placed on the designated material table to the annealing furnace. The detailed working process of the material trolley is as follows: After the material trolley receives the confirmation signal and operation instruction of the automated central control system that the material coil has been lifted, the trolley A of the material trolley automatically moves forward along the material table track. After it moves into position, the material rack pallet of trolley A automatically rises. After the pallet is lifted into position, it lifts up the material rack with the material coil placed on it. The trolley A of the material trolley automatically returns. After it returns to its position; the material rack pallet It automatically descends. After it automatically descends into place, the material cart starts to automatically move horizontally. After it automatically detects that it has reached the material position in front of the annealing furnace, the material cart automatically stops. The material rack tray of the material cart automatically rises. After it is lifted into place, trolley A automatically moves forward to send the material rack into the annealing furnace. After it moves into place, the material rack tray automatically descends and places the material rack containing the coils on the support frame in the annealing furnace. Trolley A automatically returns. After the annealing furnace receives the trolley return signal, the furnace door automatically closes and closes into place, and heating and annealing begin. The transfer task before the coil annealing is completed, and the execution result information is returned to the MES system through the automated central control system, WMS and scheduling system in turn;

[0061] The annealing furnace control system controls the annealing furnace to start annealing according to the received annealing process information;

[0062] After annealing is completed, the annealing furnace control system feeds back information to the MES system through the automated central control system, WMS, and scheduling system. Based on the production tasks issued by the MES and the operation plans formulated by the WMS and scheduling system, the automated central control system instructs the trolley control system to control the trolley to transport the annealed coil in the annealing furnace to the cooling chamber for cooling and / or to a designated rack for natural cooling. The detailed process of the trolley is as follows: The trolley automatically traverses horizontally to the corresponding annealing furnace and automatically stops after detecting that it is in place. After the annealing furnace control system receives the signal that the trolley is in place, it automatically opens the furnace door. After the trolley control system receives the signal that the furnace door is opened in place, trolley car A automatically moves forward. After moving forward in place, the rack tray automatically rises and holds the rack. After the rack rises in place, the trolley car automatically retreats and after retreating in place, the trolley automatically traverses horizontally to the front of the designated cooling chamber. After the trolley detects that it is in place, it automatically stops and the rack tray automatically rises. After the cooling chamber receives the signal that the trolley has arrived, the chamber door automatically opens. After the trolley receives the signal that the chamber door is opened in place and the rack tray has risen in place, the trolley car automatically moves forward and after moving forward in place, the rack tray automatically descends, placing the rack on the support frame in the cooling chamber. After the rack tray descends in place, the trolley car automatically retreats. After the cooling chamber receives the signal that the trolley car has retreated in place, it automatically closes the chamber door. After the chamber door is closed in place, it automatically starts the cooling fan to start forced air cooling. The cooling chamber and fan room control system and / or the natural cooling rack system online monitor the temperature of the coil. After the coil is cooled to the set temperature, the fan automatically stops;

[0063] After cooling is completed, the cooling chamber and fan room control system or the natural cooling rack system feeds back the cooling completion information to the MES system through the automated central control system, WMS, and scheduling system. After the MES confirms, it issues a transfer task instruction to the trolley control system and / or the intelligent crane system through the WMS, scheduling system, and automated central control system;

[0064] According to the received task instruction, the trolley control system controls the trolley to transfer the cooled coil from the cooling chamber and / or the natural cooling rack to the designated rack, and the intelligent crane system controls the crane to transfer the cooled coil on the designated rack to the high-level dock position or the AGV position. After the transfer is completed, the intelligent crane system sends the execution result information to the MES system through the automated central control system, WMS, and scheduling system respectively. The work of one scheduling cycle is completed, and a new scheduling cycle is entered. Repeating the above steps is sufficient.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
