Development of sensor interface used on the education site and integration on the hyper media

首先，针对国产PC机所不具备的传感器接口，采用并行口设计了一种通用的传感器接口，包括数字I/O和模拟输入。其次，开发了利用微弱电波或红外线传输的无线方式的传感器接口。将传感器的模拟数据转换为不同的频率，并通过串口将数据转发给PC机。另一方面，考虑到环境和身体信息的重要性，研制了用于掌握学习情况的心跳呼吸变化测量装置和简单的三维地震传感器。此外，还对传感器信息与超媒体的融合进行了基础性研究，以期提高超媒体在互联网普及中的重要性。即通过网络交换信息的超媒体系统的考试操作是利用一个分散的数据库、Java和Java脚本来完成的，由于学校在现场讲授天气等信息时希望将各种信息与另一个区域进行比较，所以对传感器的测量结果进行了处理，改进等活动计划在以后继续系统运行的同时进行。

The purpose of this research was in developing the sensor interface which was able to be used on the education site and integration on the hyper media.First of all, a general-purpose sensor interface which including digital I/O and analog input was developed by using a parallel port because the sensor interface which the personal computer of the domestic production was not possessed. And next, the sensor interface of the wireless method transmitted by a slight electric wave or infrared rays was developed. Analog data of the sensor was converted to the different frequency and the data is forwarded to the personal computer through the serial port. In addition, the improvement was added while doing the class practice in which these sensor interfaces were used.On the other hand, a heart beat breath change measurement device for the grasp of the study situation and a simple three dimension earthquake sensor ware developed in consideration of an importance the environment and body information. In addition, the basic study was researched by which the integration of sensor information into the hyper media targeting HTML to which importance increased in the popularization of the internet. That is, the examination operation of the hyper media system which exchanged information by the internet was done by using a decentralized data base, Java and the Java script, which treated the measurement result of the sensor because the comparison between various information and another region was hoped when the weather etc.were taught in the school site.The activity of the improvement etc.is scheduled to be done while being continue the system operation in the future.
