[0034] In order to better understand the purpose, structure and function of the present invention, the modular layout and resource optimization layout method of a production line equipment of the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] This embodiment first provides a modular layout of production line equipment, and 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 the process flow are designed into a modular structure, and the layout adopts a layout method combining a linear layout and a modular layout; the modular layout is as Figure 1 shown, mainly including but not limited to: production line control area, test preparation area, normal temperature debugging area, regional laboratory environment debugging area, environment debugging area, vibration debugging area, troubleshooting debugging area, material distribution area and storage area. Next, in combination with Figure 2 , each modular area will be further elaborated.

[0037] The equipment configuration standards of the production line control area include the overall control system, production management system and production data acquisition system of the production line, and these three systems interact with personnel through a visualization terminal; as Figure 2As shown in the figure, the production line control area communicates with the troubleshooting and debugging area, normal temperature debugging area, regional laboratory environment debugging area, environment debugging area, material distribution area, and storage area, and collects data from each area in real time to the production data acquisition system; ensure that the location of the production line control area is adjacent to the storage area and the debugging preparation area. Generally, the distance constraint is ≤5m, reducing the distance of material and data transmission, thereby optimizing the operation efficiency of the production line. The overall control system of the production line is the command center of the entire production line, and realizes real-time monitoring and control of each device through a programmable logic controller (PLC) and an industrial computer (IPC). This system manages operations such as starting, pausing, and emergency shutdown of the production line by collecting and analyzing the device status, so as to ensure that the device operates safely and efficiently according to the preset process. The operator interacts with the system through a visual control panel or a touch screen terminal, facilitating 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 reasonable allocation and efficient execution of production tasks. This system stores data and schedules tasks through an industrial server and a database server, tracks the production progress, arranges task priorities, and coordinates the material supply of the storage area and the material distribution area. Managers can view the production status in real time through the production management software on a computer or a tablet, adjust the production plan and resource allocation to ensure the smooth implementation of the production plan. The production data acquisition system collects environmental and device status data from each production area in real time by connecting data acquisition terminals such as sensors and barcode scanners. This system transmits key data such as temperature, humidity, vibration, and production progress to the database, and issues an alarm when an abnormality occurs, assisting the overall control system to respond quickly. The data acquisition system processes data through edge computing devices to ensure the accuracy and timeliness of the data. Operators can monitor and analyze this data through a visual platform, providing a basis for optimizing the production line.

[0038] The production line control area conducts production plan scheduling through the overall control system of the production line. According to the order requirements and production plan, it reasonably distributes the task load of each debugging area, dynamically adjusts the production task priorities of each area, and ensures the overall coordination of the production line; it monitors the operating status of all devices in real time through the production data acquisition system, and collects information such as the working status, running time, failure rate, and device health status of the devices. Ensure that the production line operates on the basis of high efficiency, coordination, and flexibility.

[0039] The equipment configuration standards in the test preparation area include test fixtures and jigs for fixing and positioning the products to be tested; 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 normal temperature debugging area and the troubleshooting and debugging area. Generally, the distance constraint is ≤5m to minimize the material transmission time. In this way, by optimizing the transportation time, it can ensure that the equipment and materials can be quickly transferred to the normal temperature debugging area and other relevant areas.

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

[0041] Using RFID tags (radio frequency identification tags) or a two-dimensional code system, relevant test parameters and preliminary test data are recorded for each product when it is in the test preparation area. The independent data file of each product is transmitted to subsequent debugging areas through Internet of Things (IoT) devices. In this way, when the product enters other debugging areas, the production data acquisition system can automatically read the previous test data and set the debugging equipment accordingly to ensure seamless connection and test continuity.

[0042] Using an automated guided vehicle (AGV) or an intelligent conveyor belt, automatic transfer of products between various debugging areas is achieved. The conveyor system is equipped with an identification system (such as a laser or vision sensor) that can automatically identify product tags and accurately deliver them to the target debugging area according to the preset path.

[0043] Through the PLC (programmable logic controller) network and the HMI (human-machine interface) system, the operators in the test preparation area can monitor the equipment status of other debugging areas in real time and remotely control them through the network. When parameter adjustment or equipment reconfiguration is required in a certain area, the operators can set it in advance through the remote system to ensure that no additional equipment adjustment is needed when the product enters this area.

[0044] The equipment configuration standards in the normal temperature debugging area include: electrical performance test equipment, such as oscilloscopes, multimeters, etc.; function test equipment, such as special testers, programmers, etc.; preliminary detection equipment, such as a vision detection system. As Figure 2 shown, the normal temperature debugging area conducts equipment parameter transmission with the test preparation area, the vibration debugging area, and the environment debugging area, conducts communication transmission with the production line control area, and conducts product transfer with the domain laboratory environment debugging area; the normal temperature debugging area is adjacent to the debugging preparation area, the troubleshooting debugging area, and the laboratory environment debugging area, with a distance constraint ≤ 2m, thereby reducing the distance and time for product transfer between modules. After completing the preliminary debugging work in cooperation with the test preparation area, the normal temperature debugging area transfers the products to the domain laboratory environment debugging area and the environment debugging area.

[0045] The equipment configuration standards for the domain laboratory environment debugging area include equipment for simulating laboratory environments, such as high-precision power supplies and precision temperature control equipment; high-precision test equipment, such as high-precision oscilloscopes and spectrum analyzers; and professional laboratory software for data analysis and report generation. As Figure 2 shown, it conducts product transfer with the normal temperature debugging area and the environmental debugging area, transmits equipment parameters to the test preparation area, and conducts communication transmission with the production line control area; it is adjacent to the vibration debugging area, and generally, the distance constraint is ≤2m; the domain laboratory environment debugging area conducts debugging by simulating the laboratory environment to ensure the functions and performance of products under laboratory conditions. The domain laboratory environment debugging area cooperates with the normal temperature debugging area and the test preparation area to provide more stringent test conditions.

[0046] The equipment configuration standards for the environmental debugging area include high and low temperature test chambers for simulating different temperature environments; damp heat test chambers for simulating high humidity environments; and environmental simulation equipment, such as salt spray test chambers and aging test equipment. The environmental debugging area works in coordination with the domain laboratory environment debugging area and the normal temperature debugging area. As Figure 2 shown, it conducts product transfer with the domain laboratory environment debugging area and the troubleshooting debugging area, transmits equipment parameters to the normal temperature debugging area and the test preparation area, and conducts communication transmission with the production line control area. The environmental debugging area conducts debugging by simulating different environmental conditions (such as high and low temperatures, humidity, etc.) to ensure the reliability of products under various environments. The environmental debugging area closely cooperates with the domain laboratory environment debugging area and the normal temperature debugging area to provide comprehensive environmental debugging support.

[0047] The equipment configuration standards for the vibration debugging area include vibration test benches for simulating vibration environments; acceleration sensors for measuring vibration responses; and vibration control systems for controlling and monitoring vibration tests. The vibration debugging area is adjacent to the domain laboratory environment debugging area and the troubleshooting debugging area, conducts product transfer with the troubleshooting debugging area, conducts communication transmission and equipment parameter transmission with the test preparation area, and conducts equipment parameter transmission with the normal temperature debugging area. The vibration debugging area conducts vibration tests on products to ensure the stability and reliability of products under vibration environments. The vibration debugging area works in coordination with the environmental debugging area and the test preparation area to complete vibration tests on products.

[0048] The equipment configuration standards for the troubleshooting debugging area include fault diagnosis equipment, such as fault analyzers and X-ray detection equipment; repair tools, such as welding equipment and disassembly tools; and in-circuit test systems (ICT) for real-time diagnosis and repair of faults. The troubleshooting debugging area is adjacent to the normal temperature debugging area and the vibration debugging area to optimize the transmission efficiency between modules; it conducts product transfer with the environmental debugging area and the vibration debugging area, and conducts communication transmission with the production line control area. The troubleshooting debugging area is responsible for troubleshooting and repairing problems found during the debugging process to ensure that all problems are solved.

[0049] The equipment configuration standards for the material distribution area include an automated storage and retrieval system for storing and managing materials, an automated guided vehicle (AGV) for automatically transporting materials, and a material management system for tracking and managing material inventory. The material distribution area is adjacent to the storage area. Generally, the distance constraint is ≤10m. The material distribution area is responsible for timely delivering the materials and equipment required for production to each commissioning area to ensure the smooth progress of the commissioning work.

[0050] The equipment configuration standards for the storage area include storage racks for storing raw materials and finished products, a barcode scanning system for identifying and managing materials and products, and an inventory management system for managing and optimizing inventory. The storage area is located at the entrance and exit of the production line. The storage area is used to store the raw materials required for production and the products that have been successfully commissioned to ensure the orderly management of materials and the storage of products. The storage area works in coordination with the material distribution area and the production line control area to ensure an adequate supply of production materials and the storage management of products.

[0051] As Figure 3 shown above, the electronic information commissioning production line has been modularly laid out. The production line is divided into multiple independently operating modular units, and each module is arranged in a linear manner to achieve a highly flexible configuration of equipment and processes. This ensures product reliability and commissioning efficiency. However, further optimization is still required to ensure that the layout not only meets the actual requirements of space and equipment configuration but also minimizes the material flow time and production costs to the greatest extent. Therefore, this embodiment also provides a resource optimization layout method for the modular layout of the production line based on multi-objective constraint optimization to achieve the optimization and adjustment of the equipment transportation process. The specific steps are as follows:

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

[0053] First, analyze the information transmission and material transfer between each module to ensure the maximization of efficiency in terms of the distance and transportation time between modules. At the same time, considering the actual needs, ensure the minimization of the total cost of the production line. Therefore, the determined optimization objectives include the total cost C i , the equipment and operation costs of the i-th functional module, including equipment acquisition costs, daily maintenance costs, etc.; the distance D ij between the i-th module and the j-th module, which represents the Euclidean distance between these two modules and indicates the transportation distance of materials or products between them. The calculation formula is: where x i , y i are the position coordinates of the i-th model, and x j , y j are the position coordinates of the j-th model; the transportation time T ij between module i and module j, which depends on the distance D ij between the two modules and the transportation speed v. The calculation formula is:

[0054] Then determine the constraints, including:

[0055] Spatial constraint: The total area cannot exceed the available space, i.e., A i is the area of the i-th module in square meters, representing the space occupied by each module in the production line. This constraint means that the sum of the areas of all modules cannot exceed the total available area L of the production line.

[0056] Proximity constraint: Modules that need to cooperate closely must be within the maximum allowed distance range, i.e., D ij ≤D max . This constraint ensures that the distance D ij between modules that need to interact frequently does not exceed the maximum allowed distance D max .

[0057] Transportation time constraint: The transportation time for material flow between modules needs to be controlled within the specified time range, i.e., T ij ≤T max . This constraint limits the transportation time T ij between modules from exceeding the maximum transportation time T specified for the production line max .

[0058] Module equipment configuration constraint: This constraint ensures that the number of equipment M i for each module is not less than the minimum requirement of the module to ensure the normal operation of the functional module. That is

[0059] Module position non-overlap constraint: This constraint ensures that the position areas of any two functional modules do not intersect, i.e., to avoid physical overlap between modules. That is where P i =(x i ,y i ) represents the coordinate position of the i-th functional module, indicating the specific position of the module in the plane layout of the production line, where x i and y i are its abscissa and ordinate respectively.

[0060] Weight coefficient constraint: λ1 and λ2 are the weight coefficients in the objective function, representing the relative importance of the transportation distance and transportation time between modules in the total cost. And it satisfies 0≤λ1≤1, 0≤λ2≤1, λ1 + λ2 = 1. It is used to adjust the influence of the distance D ij and the transportation time T ij on the final layout cost Z.

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

[0062]

[0063] Specifically, the production line control area is restricted by the distance D between modules ij , generally, the distance constraint D ij ≤ 5m, ensuring that the position of the production line control area is adjacent to the storage area and the commissioning preparation area, reducing the distance of material and data transmission, thereby optimizing the operation efficiency of the production line. The test preparation area is based on the space constraint A of the mathematical model i and the transportation time constraint T ij , the test preparation area is adjacent to the normal temperature commissioning area and the troubleshooting commissioning area. Generally, the distance constraint D ij ≤ 5m, to minimize the material transmission time. In this way, by optimizing T ij , it is ensured that equipment and materials can be quickly transferred to the normal temperature commissioning area and other relevant areas. The area A of the normal temperature commissioning area i is optimized through space constraints and is adjacent to the commissioning preparation area and the troubleshooting commissioning area. Through the D ij constraint ≤ 2m, thereby reducing the distance and time T of product transmission between modules ij . The number of devices M in this area i is optimized according to the module device configuration constraint to ensure that there are sufficient devices to guarantee the normal operation of product commissioning work. In the domain laboratory environment commissioning area, generally, the distance constraint D ij ≤ 2m, through the distance D between modules ij and the transportation time constraint T ij , ensuring efficient material transmission from the normal temperature commissioning area to the domain laboratory environment commissioning area. The environment commissioning area is independently set through the space constraint A i , ensuring a reasonable layout of each device in the area, maximizing space utilization, and working in coordination with the domain laboratory environment commissioning area and the normal temperature commissioning area. Through the optimization of D ij , generally, the distance constraint D ij ≤ 2m, ensuring that the product can complete the transition from one commissioning area to another with the shortest distance and time. The position of the vibration commissioning area is optimized by the non-overlapping constraint of the module position in the optimization model, that is through the optimization of D ij , generally, the distance constraint D ij ≤ 2m, ensuring adjacent to the domain laboratory environment commissioning area and the troubleshooting commissioning area and avoiding overlapping with other areas, maximizing the use of available space. The troubleshooting commissioning area is optimized through the distance constraint D ij , generally, the distance constraint D ij ≤ 5m, adjacent to the normal temperature commissioning area and the vibration commissioning area, optimizing the transmission efficiency between modules. By optimizing the number of devices Mi Ensure that the troubleshooting and debugging area has sufficient equipment to handle the faults that occur during the debugging process. The material distribution area optimizes the transportation time constraint T in the model ij , and the location of the material distribution area is optimized. Through the optimization of the distance constraint D ij , it is adjacent to the storage area. Generally, the distance constraint D ij ≤10m. By optimizing T ij and D ij , ensure that the material distribution can be carried out efficiently and economically, reduce the stagnation time of the production line, and improve the overall operation efficiency.

[0064] Step 2: Solve based on the multi-objective constraint optimization method; this mathematical model is a typical multi-objective optimization problem, and the genetic algorithm is used for solving. The following table is the pseudocode for the optimization of the equipment layout of the debugging production line based on the genetic algorithm.

[0065]

[0066]

[0067] The solution steps are as follows: First, encode each layout plan into the gene sequence of a genetic individual, which is represented as an individual in the population, and initialize several random layout plans. Then, calculate the fitness value of each individual according to the objective function Z. Next, select the individuals with higher fitness through the selection operation to enter the next generation. Then, generate new offspring individuals through the crossover operation, and mutate the individuals with a certain probability to increase the diversity of the population. After each round of iteration, recalculate the fitness values of all individuals, and retain the individual with the optimal fitness, and eliminate the inferior individuals. This process is repeated until the maximum number of iterations is reached or the fitness value converges, and finally output the layout plan with the optimal fitness.
