[0034] To better understand the purpose, structure, and function of this invention, the following detailed description, in conjunction with the accompanying drawings, provides a method for modular layout and resource optimization layout of production line equipment according to this invention.

[0035] This embodiment first provides a modular layout for production line equipment, which structurally arranges the equipment of the electronic information debugging production line.

[0036] Specifically, based on the modular debugging flexible production line equipment, the modular debugging production line equipment and process flow are designed into a modular structure, and the layout adopts a combination of linear and modular layouts; the modular layout is as follows: Figure 1 As shown, it mainly includes, but is not limited to: production line control area, test preparation area, ambient temperature debugging area, domain laboratory environment debugging area, environmental debugging area, vibration debugging area, troubleshooting and debugging area, material distribution area, and storage area. The following will combine... Figure 2 The various modular areas are further elaborated upon.

[0037] The equipment configuration standard of the production line control area includes the overall control system, production management system, and production data acquisition system of the production line. These three systems interact with personnel through a visual terminal; for example... Figure 2As shown, the production line control area communicates with the troubleshooting and debugging area, ambient temperature debugging area, domain laboratory environment debugging area, environmental debugging area, material distribution area, and warehousing area, collecting data from each area in real time to the production data acquisition system. The production line control area is ensured to be adjacent to the warehousing area and debugging preparation area, generally with a distance constraint of ≤5m, reducing the distance for material and data transmission and thus optimizing the production line's operating efficiency. The overall production line control system is the command center of the entire production line, using programmable logic controllers (PLCs) and industrial computers (IPCs) to achieve real-time monitoring and control of each piece of equipment. This system manages the start-up, pause, and emergency shutdown of the production line by collecting and analyzing equipment status data to ensure the equipment operates safely and efficiently according to preset procedures. Operators interact with the system through a visual control panel or touchscreen terminal for easy real-time monitoring and operation of the production process. The production management system is responsible for the overall scheduling and resource management of the production line, ensuring the rational allocation and efficient execution of production tasks. This system uses industrial servers and database servers for data storage and task scheduling, tracking production progress, prioritizing tasks, and coordinating material supply between the warehousing and material distribution areas. Managers can monitor production status in real time and adjust production plans and resource allocation using production management software on computers or tablets to ensure the smooth implementation of production plans. The production data acquisition system collects environmental and equipment status data from various production areas in real time by connecting to data acquisition terminals such as sensors and barcode scanners. This system transmits key data such as temperature, humidity, vibration, and production progress to a database and issues alarms when anomalies occur, assisting the overall control system in responding quickly. The data acquisition system processes data through edge computing devices, ensuring data accuracy and timeliness. Operators can monitor and analyze this data through a visualization platform, providing a basis for production line optimization.

[0038] The production line control area uses the overall control system of the production line to schedule production plans. Based on order demand and production plans, it rationally allocates the workload of each testing area and dynamically adjusts the production task priority of each area to ensure the overall coordination of the production line. A production data acquisition system monitors the operating status of all equipment in real time, collecting information such as equipment working status, running time, failure rate, and equipment health status. This ensures that the production line operates efficiently, in a coordinated and flexible manner.

[0039] The equipment configuration standard in the test preparation area includes test fixtures and jigs for fixing and positioning the product under test; test tooling, such as electrical connectors and adapters; and a parameter setting system for setting and managing test parameters. The test preparation area is adjacent to the ambient temperature test area and the troubleshooting test area. Generally, the distance is limited to ≤5m to minimize material transport time. This optimizes transportation time, ensuring that equipment and materials can be quickly transferred to the ambient temperature test area and other relevant areas.

[0040] Through an intelligent parameter setting system, the test preparation area works closely with the ambient temperature calibration area, domain laboratory environment calibration area, environmental calibration area, and vibration calibration area to provide necessary equipment and parameter support. It can uniformly manage and allocate equipment parameters in the environmental calibration area, domain laboratory environment calibration area, ambient temperature calibration area, and vibration calibration area, and share these parameters in real time with subsequent calibration areas (such as the ambient temperature calibration area and environmental calibration area). This ensures that the test conditions and parameters used in each calibration area are completely consistent with product requirements, avoiding calibration deviations caused by parameter mismatches.

[0041] Using RFID tags (Radio Frequency Identification tags) or QR code systems, each product's relevant test parameters and preliminary test data are recorded in the test preparation area. Each product's independent data file is transmitted to the subsequent debugging area via Internet of Things (IoT) devices. In this way, when a product enters another debugging area, the production data acquisition system can automatically read the previous test data and set up the debugging equipment accordingly, ensuring seamless integration and testing continuity.

[0042] Automated guided vehicles (AGVs) or intelligent conveyor belts are used to automatically transfer products between various testing areas. The conveyor system is equipped with an identification system (such as laser or vision sensors) that can automatically identify product labels and accurately deliver them to the target testing area according to a preset path.

[0043] Through a PLC (Programmable Logic Controller) network and an HMI (Human Machine Interface) system, operators in the test preparation area can monitor and remotely control the equipment status of other test areas in real time via the network. When a certain area requires parameter adjustments or equipment reconfiguration, operators can make advance settings through the remote system to ensure that no additional equipment adjustments are needed when the product enters that area.

[0044] The standard equipment configuration for the ambient temperature testing area includes: electrical performance testing equipment, such as oscilloscopes and multimeters; functional testing equipment, such as dedicated testers and programmers; and preliminary inspection equipment, such as vision inspection systems. Figure 2 As shown, the ambient temperature debugging area transmits equipment parameters to the test preparation area, vibration debugging area, and environmental debugging area; it also communicates with the production line control area and transfers products to the domain laboratory environmental debugging area. The ambient temperature debugging area is adjacent to the debugging preparation area, troubleshooting debugging area, and laboratory environmental debugging area, with a distance constraint of ≤2m to reduce the distance and time of product transfer between modules. The ambient temperature debugging area works in conjunction with the test preparation area to complete initial debugging work before transferring the product to the domain laboratory environmental debugging area and the environmental debugging area.

[0045] The equipment configuration standard for the domain laboratory environment debugging area includes equipment simulating a laboratory environment, such as high-precision power supplies and precision temperature control equipment; high-precision testing equipment, such as high-precision oscilloscopes and spectrum analyzers; and professional laboratory software for data analysis and report generation. Figure 2 As shown, the product is transferred to the ambient temperature and environmental testing areas, equipment parameters are transmitted to the test preparation area, and communication is established with the production line control area. It is adjacent to the vibration testing area, with a typical distance constraint of ≤2m. The domain laboratory environmental testing area simulates a laboratory environment for testing, ensuring the product's functionality and performance under laboratory conditions. This area collaborates with the ambient temperature and test preparation areas to provide more stringent testing conditions.

[0046] The environmental conditioning area is equipped with standard equipment including high and low temperature test chambers to simulate different temperature environments; humidity test chambers to simulate high humidity environments; and environmental simulation equipment such as salt spray test chambers and aging test equipment. The environmental conditioning area works in conjunction with the domain laboratory environmental conditioning area and the ambient temperature conditioning area, such as... Figure 2 As shown, the system facilitates product transfer between the domain laboratory environmental testing area and the troubleshooting testing area; transmits equipment parameters with the ambient temperature testing area and the test preparation area; and communicates with the production line control area. The environmental testing area simulates different environmental conditions (such as high and low temperatures, humidity, etc.) to ensure product reliability under various environments. The environmental testing area works closely with the domain laboratory environmental testing area and the ambient temperature testing area to provide comprehensive environmental testing support.

[0047] The vibration testing area is equipped with a vibration test bench to simulate vibration environments; accelerometers to measure vibration response; and a vibration control system to control and monitor vibration testing. Adjacent to the environmental testing and troubleshooting areas, the vibration testing area facilitates product transfer with the troubleshooting area, communication and equipment parameter transmission with the test preparation area, and equipment parameter transmission with the ambient temperature testing area. The vibration testing area performs vibration tests on products to ensure their stability and reliability under vibration conditions. Working collaboratively with the environmental testing and test preparation areas, the vibration testing area completes the vibration testing of the products.

[0048] The equipment configuration standards for the troubleshooting and commissioning area include fault diagnosis equipment, such as fault analyzers and X-ray inspection equipment; maintenance tools, such as welding equipment and disassembly tools; and an online testing system (ICT) for real-time fault diagnosis and repair. The troubleshooting and commissioning area is adjacent to the ambient temperature commissioning area and vibration commissioning area, optimizing the transmission efficiency between modules; it also facilitates product transfer with the environmental commissioning area and vibration commissioning area, and communication transmission with the production line control area. The troubleshooting and commissioning area is responsible for investigating and repairing problems discovered during the commissioning process, ensuring that all problems are resolved.

[0049] The standard equipment configuration of the material distribution area includes an automated storage and retrieval system (AS / RS) for storing and managing materials; Automated Guided Vehicles (AGVs) for automated material transport; and a material management system for tracking and managing material inventory. The material distribution area is adjacent to the storage area, generally with a distance constraint of ≤10m. The material distribution area is responsible for the timely delivery of materials and equipment required for production to various commissioning areas, ensuring the smooth progress of commissioning work.

[0050] The standard equipment configuration of the storage area includes storage racks for storing raw materials and finished products; a barcode scanning system for material and product identification and management; and an inventory management system for managing and optimizing inventory. The storage area is located at the production line entrance / exit. It stores raw materials required for production and completed products, ensuring orderly material management and product storage. The storage area works in conjunction with the material distribution area and production line control area to ensure sufficient production materials and proper product storage management.

[0051] like Figure 3 As shown, the above-described electronic information debugging production line adopts a modular layout, dividing the production line into multiple independently operable modular units, and arranging the modules in a linear manner to achieve a high degree of flexibility in equipment and process configuration. This ensures product reliability and debugging efficiency, but further optimization is needed to ensure that the layout meets the actual requirements of space and equipment configuration while minimizing material flow time and production costs. Therefore, this embodiment also provides a resource optimization layout method for modular production line layout based on multi-objective constraint optimization, realizing the optimization and adjustment of equipment transportation processes. The specific steps are as follows:

[0052] Step 1: Determine the optimization objective and establish a mathematical model;

[0053] First, we analyze the information transmission and material handling between modules; ensuring maximum efficiency in balancing distance and transportation time between modules, while simultaneously minimizing the total production line cost based on actual needs. Therefore, the optimization objectives include the total cost C. i The equipment and operating costs of the i-th functional module, including equipment purchase costs and daily maintenance costs; the distance D between modules. ij The Euclidean distance between the i-th module and the j-th module represents the transportation distance of materials or products between these two modules, and is calculated using the following formula: Where x i ,y i Let x be the position coordinate of the i-th model. j ,y j Let T be the location coordinates of the j-th model; and T be the transportation time. ij The transport time between module i and module j depends on the distance D between the two modules. ij The formula for calculating the transport speed v is:

[0054] Then determine the constraints, including:

[0055] Space constraints: The total area cannot exceed the available space, i.e. A i Let be the area of ​​the i-th module, in square meters, representing the space occupied by each module in the production line. This constraint states that the total area of ​​all modules cannot exceed the total usable area L of the production line.

[0056] Proximity constraint: Modules that need to fit together must be within the maximum allowable distance range, i.e., D. ij ≤D max This constraint ensures the distance D between modules that require frequent interaction. ij Not exceeding the maximum allowable distance D max .

[0057] Transportation time constraints: The transportation time for materials between modules needs to be controlled within a specified time range, i.e., T. ij ≤T max This constraint limits the inter-module transport time T. ij The maximum transport time T specified by the production line must not be exceeded. max .

[0058] Module device configuration constraint: This constraint ensures that the number of devices M in each module is... i Minimum requirements for modules This is to ensure the normal operation of the functional modules.

[0059] Module location non-overlap constraint: This constraint ensures that the location regions of any two functional modules will not intersect, thus avoiding physical overlap between modules. Where P i =(x i ,y i ) represents the coordinate position of the i-th functional module, indicating the specific location of this module in the production line layout, where x i and y i These are its x-coordinate and y-coordinate, respectively.

[0060] Weighting coefficient constraints: λ1 and λ2 are weighting coefficients in the objective function, representing the relative importance of inter-module transportation distance and transportation time in the total cost, respectively. They satisfy 0 ≤ λ1 ≤ 1, 0 ≤ λ2 ≤ 1, and λ1 + λ2 = 1. These are used to adjust the distance D. ij and transportation time T ij Impact on the final layout cost Z.

[0061] Based on this, the following mathematical model is established:

[0062]

[0063] Specifically, the production line control area uses distance constraints between modules to define D. ij In general, distance constraint D ij ≤5m, ensuring the production line control area is adjacent to the storage area and debugging preparation area, reducing the distance for material and data transmission, thereby optimizing production line operating efficiency. The testing preparation area is based on the spatial constraints A of the mathematical model. i and transportation time constraints T ij The test preparation area is adjacent to the ambient temperature debugging area and the troubleshooting debugging area. Under normal circumstances, the distance constraint D is... ij ≤5m, to minimize material transfer time. This can be achieved by optimizing T. ij This ensures that equipment and materials can be quickly transferred to the ambient temperature test area and other relevant areas. The area of ​​the ambient temperature test area is A. i Through spatial constraint optimization, it is adjacent to the debugging preparation area and the troubleshooting debugging area. Through D... ij Constraints are ≤2m, thereby reducing the distance and time T for product transfer between modules. ij The number of devices in this area is M. i Based on module device configuration constraints Optimization is performed to ensure sufficient equipment is available to guarantee the normal operation of product debugging. In a typical domain laboratory environment debugging area, the distance constraint D... ij ≤2m, through inter-module distance constraint D ij and transportation time constraints T ij This ensures efficient material transfer from the ambient temperature test area to the domain laboratory test area. The environmental test area utilizes space constraints A... i Independent setup ensures a rational layout of equipment within the area, maximizes space utilization, and coordinates with the domain laboratory environment testing area and ambient temperature testing area. Through D ij In general, the optimization of distance constraint D ij ≤2m, ensuring the product can transition from one testing zone to another with the shortest distance and time. The location of the vibration testing zone is determined by non-overlapping module positions in the optimization model, i.e. Through D ij In general, the optimization of distance constraint D ij ≤2m, ensuring adjacency with the domain laboratory environment commissioning area and troubleshooting commissioning area, and avoiding overlap with other areas to maximize the use of available space. The troubleshooting commissioning area is constrained by distance D. ij In general, the optimization of distance constraint D ij ≤5m, adjacent to the ambient temperature test area and vibration test area, optimize the transmission efficiency between modules. This is achieved by optimizing the number of devices (M).i Ensure the troubleshooting and debugging area has sufficient equipment to handle faults that occur during debugging. The material distribution area optimizes the transportation time constraint T in the model. ij The location of the material distribution area has been optimized by using distance constraints D. ij The optimization, adjacent to the storage area, generally involves a distance constraint D. ij ≤10m, through optimization of T ij and D ij This ensures that material delivery can be carried out efficiently and economically, reducing production line downtime and improving overall operational efficiency.

[0064] Step 2: Solve the problem using a multi-objective constraint optimization method; this mathematical model is a typical multi-objective optimization problem, solved using a genetic algorithm. The table below shows the pseudocode for optimizing the layout of equipment on a production line based on a genetic algorithm.

[0065]

[0066]

[0067] The solution steps are as follows: First, each layout scheme is encoded into a gene sequence of a genetic individual, representing an individual in the population, and several random layout schemes are initialized. Next, the fitness value of each individual is calculated according to the objective function Z, and then individuals with higher fitness are selected to enter the next generation through a selection operation. New offspring individuals are then generated through a crossover operation, while individuals are mutated with a certain probability to increase population diversity. After each iteration, the fitness values ​​of all individuals are recalculated, and the individual with the best fitness is retained, while the individuals with poorer fitness are eliminated. This process is repeated until the maximum number of iterations is reached or the fitness values ​​converge, finally outputting the layout scheme with the best fitness.

Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
