Translated fromChinese技术领域technical field
本发明涉及实验系统，尤其涉及一种虚实融合的工业工程综合实验系统。The invention relates to an experiment system, in particular to an industrial engineering comprehensive experiment system integrating virtual reality.
背景技术Background technique
IE（Industrial Engineering，工业工程）是工程技术与管理科学相结合的交叉学科。国际上，工业工程的主要研究对象是生产系统和服务系统。在我国IE还处在发展初级阶段，主要研究工业系统的效率,它利用自然科学和其它技术对研究对象进行观察、实验、分析、设计。工业工程的许多重要技术和理论方法都来源于生产实际，IE工程师必然具有很强的实践和工程分析与设计能力。因此，IE具有很强的实践性和应用性，实践教学是其教学过程中不可缺少的一环，是培养学生实践和综合运用所学知识解决实际问题能力，保证人才培养质量的必要手段。IE (Industrial Engineering) is an interdisciplinary subject combining engineering technology and management science. Internationally, the main research objects of industrial engineering are production systems and service systems. In our country, IE is still in the primary stage of development, and it mainly studies the efficiency of industrial systems. It uses natural science and other technologies to observe, experiment, analyze and design the research objects. Many important technologies and theoretical methods of industrial engineering are derived from actual production, and IE engineers must have strong practical and engineering analysis and design capabilities. Therefore, IE has strong practicality and application. Practical teaching is an indispensable part of its teaching process. It is a necessary means to cultivate students' ability to practice and comprehensively use the knowledge they have learned to solve practical problems and ensure the quality of talent training.
1993年我国第一批IE专业在若干所高校设立以来，已经发展了20年，从专业规模、教学体系等方面取得了长足的进步。但IE专业的实验设施和实验条件都很薄弱，并且由于IE与生产实际的关联度高且涉及面广，在有限资金的条件下，难以将IE面临的各种系统及其运行状态在实验室中真实地展现出来，学生无法在实验过程中真正体会到真实的企业生产环境，导致整体实验效果差。因此，如何根据自己的专业特色，在现有资源条件下构建能够充分模拟企业生产实际环境，能够全面覆盖，并有机集成工业工程学科知识的实验体系，显得尤为重要。Since the first batch of IE majors in my country was established in several colleges and universities in 1993, it has developed for 20 years and has made great progress in terms of professional scale and teaching system. However, IE's professional experimental facilities and experimental conditions are very weak, and because IE is closely related to the actual production and involves a wide range of areas, it is difficult to integrate the various systems and their operating states faced by IE in the laboratory under the condition of limited funds. It is truly shown in the experiment, and students cannot really experience the real enterprise production environment during the experiment, resulting in poor overall experiment effect. Therefore, how to build an experimental system that can fully simulate the actual production environment of the enterprise, fully cover, and organically integrate the knowledge of industrial engineering disciplines under the existing resource conditions is particularly important.
目前国内大学工业工程的实验系统主要存在以下缺陷：At present, the experimental system of industrial engineering in domestic universities mainly has the following defects:
1）涉及面窄：由于硬件系统的限制，因此用于实验的对象一般比较简单，无法完全体现企业实际生产过程；1) Narrow coverage: Due to the limitations of the hardware system, the objects used for experiments are generally relatively simple and cannot fully reflect the actual production process of the enterprise;
2）成本高：由于需要模拟企业的硬件环境，需要购买各类硬件设备，如果需要更多的体现企业生产实际，就必须购买更多的硬件设备，导致实验平台的成本提高；2) High cost: Due to the need to simulate the hardware environment of the enterprise, it is necessary to purchase various hardware devices. If it is necessary to reflect the actual production of the enterprise, more hardware devices must be purchased, resulting in an increase in the cost of the experimental platform;
3）可扩展性不强：硬件一旦购买，就不容更换，因此，实验的内容就相对来说比较固定，不具有很好的扩展性；3) The scalability is not strong: once the hardware is purchased, it cannot be replaced. Therefore, the content of the experiment is relatively fixed and does not have good scalability;
4）实验不综合：各个实验相对独立，只注重单项知识和技术的实验，忽视工业工程各门课程紧密联系的特点，且实验不全面，学生缺乏对整个专业知识和技术的全面认识和融会贯通。4) Experiments are not comprehensive: each experiment is relatively independent, only focusing on the experiment of individual knowledge and technology, ignoring the characteristics of the close connection of various courses of industrial engineering, and the experiment is not comprehensive, students lack a comprehensive understanding and mastery of the entire professional knowledge and technology.

下面将对本系统中各个模块及其功能做详细的介绍，并细化各个功能模块工作时的交互过程。In the following, each module and its function in this system will be introduced in detail, and the interaction process of each functional module will be detailed.
首先，可将ERP模块21分为三个部分来介绍：First of all, the ERP module 21 can be divided into three parts for introduction:
1）基础建模模块211，用于配置生产各个产品所需物料、加工和装配工艺及加工和装配时所需的资源。其主要分为三个部分：产品建模模块2111、工艺建模模块2112与资源建模模块2113。产品建模模块2111，用于建立生产各个产品所需物料的配置列表，例如，生产产品A需要部件a、部件b与部件c，同时，部件c由部件d与部件e制作而成等。工艺建模模块2112，用于建立对各个产品所需物料进行加工及装配的工艺列表，例如，建立生产产品A所需部件a、部件b与部件c的加工工艺列表，并建立将部件a、部件b与部件c进行装配的工艺列表等；另外，还可以在工艺列表中设置工艺特征信息、工序卡片、作业指导书、标准工时、工艺质量规范等工艺信息。资源建模模块2113，用于建立使用加工及装配工艺时所需资源的列表，包括硬件资源与虚拟仿真资源；此处的硬件资源主要表示实际存在的资源，例如，加工机床、装配线等；虚拟仿真资源主要包括仿真模型、视频等；其作用在于当生产某一产品对应的工艺无法通过硬件资源实现时，则系统会调出相应的视频或者仿真模型，可以通过视频或仿真模型了解相应的加工过程，并且系统可以通过质量和工时分布函数，计算出该工序加工结束的时间和加工的最后质量，这些数据跟实际动手操作的工序得到的数据一样，以便后续进行质量数据分析及生产性能分析。1) The basic modeling module 211 is used to configure the materials required for the production of each product, the processing and assembly process, and the resources required for processing and assembly. It is mainly divided into three parts: product modeling module 2111 , process modeling module 2112 and resource modeling module 2113 . The product modeling module 2111 is used to create a configuration list of materials required for the production of each product. For example, the production of product A requires component a, component b, and component c, and component c is made of component d and component e. The process modeling module 2112 is used to establish a list of processes for processing and assembling the materials required for each product, for example, to establish a list of processing processes for parts a, b and c required for the production of product A, and to establish a list of parts a, The process list for assembling parts b and c; in addition, process information such as process feature information, process cards, work instructions, standard working hours, and process quality specifications can also be set in the process list.

It mainly includes: a master production planning module 2121 , a material demand calculation module 2122 , a procurement planning module 2123 , a production operation planning module 2124 and a material distribution planning module 2125 . The master production planning module 2121 is used to determine the products to be produced, that is, to form the master production plan according to the production demand. The material requirement calculation module 2122 is used to calculate the required materials for the product, for example, calculate the type and quantity of the required materials for the production of the product in combination with the configuration list of the required materials for each product in the product modeling module 2111 . The procurement plan module 2123 is used to formulate a material procurement plan according to the materials required for the product to be produced, and can also formulate a procurement plan based on the settlement result of the material demand calculation module 2122 combined with the inventory. The production operation planning module 2124 is used to formulate and distribute the production plan of the product. The material distribution planning module 2125 is used to calculate the required materials according to the production plan of the product and formulate a distribution plan.
