现场实验与远程分布式同步实验教学系统开发——以“轨道车辆制动实验”为例

Development of Teaching System of the Field and Distributed Remote Synchronous Experiment——A Case Study of Rail Vehicle Brake Experiment

以"卓越工程师培养计划"为代表的大学教育教学改革正在进行,探索培养具有工程背景,符合社会需求,具有我国教育特点的适用人才是目前工科大学面临的重要问题之一。以轨道车辆制动实验为例,针对现有的现场实验教学设备少、环境差、耗能多等问题,在原有在线测试平台的基础上,基于GPRS DTU远程数据传输技术,开发了远程分布式同步实验教学系统。实际应用表明,该系统很好地解决了上述问题,使多组学生可以同步开展实验,达到了远端与现场实验效果一致的目标,提升了学生的专业兴趣与实验参与度,符合卓越工程师培养目标。

One of the most significant tasks of technological universities in China is to cultivate engineering talents which are accordant to both the needs of our society and the characteristic of Chinese education. Taking the rail vehicle brake experiment for example, there are many problems in field experiment, such as few teaching equipment, poor environment, mass energy consumption, etc. Based on original online testing platform and GPRS DTU remote data transmission technology, a distributed remote synchronous experimental teaching system was built up. The application shows that the system can solve aforementioned problems commendably, multiple groups of students can experiment simultaneously. The system achieved the goal that the remote experimental results are consistent with the field. It elevated students＇ professional interests and participation in experiments, in line with ＂Excellent Engineer＂ training objective.
