虽然通过提供特定的教育网络解决方案，教育内联网和电子学习环境的使用已经变得很熟悉，但对于需要更复杂的计算开发的在线实验室环境来说，这是不一样的。我们知道，在线实验室为学生提供了使用网络连接执行此类任务的可能性。在本文中，我们将提出一种不同于现有专有解决方案的方法，这些解决方案在软件环境方面具有特定要求。本文提出的解决方案是基于3D语言，如VRML和Java 3d用于互联网应用程序。认识到，在一个环境中的在线实验室的教育和通用的尺寸被添加到远程控制系统所带来的经典问题，它将是必要的，以满足学生使用的3D分布式接口的模块化和可重用性方面所需的标准，应用严格的标准的学习目标。基于虚拟环境，允许学生对嵌入式系统的操作部分进行3D可视化（PLC，微控制器）的开发，以允许所述系统的控制部分的编程，本文提供了可能性：a）、阐明在哪个间隔中可以使用3D标准语言来定义3D库，其中教学组件被颗粒化，以便教育单元由一组学生可以在实践活动中重新组合以满足不同培训需求的基本学习对象; B）在全局学习环境（包括在线课程、在线指导工作、在线项目等）中定义，在线实验室的一般概念。
Although the use of educational intranet and e-learning environments has become familiar by providing specific educational in-network solutions, it is not the same thing for the environments of online laboratories, which require much more complex computing developments. We know that on-line laboratories offer a student the possibility to perform such tasks using a network connection. In this paper we will present an approach differing from the available proprietary solutions, which have specific requirements in terms of software environment. Solutions presented in this paper are based on 3D languages such as VRML and Java3d used for Internet applications. Recognizing that in an environment of on-line laboratories an educational and generic dimension is added to the classic problems posed by systems of remote control, it will be necessary to apply rigorous standards to the learning objectives to meet required standards in terms of modularity and reusability for the 3D distributed interfaces used by students. Based on a virtual environment allowing the student a 3D visualization of the operative part of an embedded system (PLC, micro-controller) developed to allow programming of the control part of said system, this paper offers the possibility to: a) clarify in which interval one can use 3D standard languages to define a 3D library in which didactic components are granulized in order for an educational unit to consist of a set of elementary learning objects that student can recombine during a practical activity to meet different training needs; b) define in a global learning environment (including online course, online directed work, online project, etc.), a generic concept of an online laboratory.
