Development of observation information server of educational

1.研究流程(1)制定规范考察了单位的种类、精度、数据量、单位制等，将可作为教材的观测数据的气象信息(温度、湿度、照度、大气压力、风向、风速、降雨量)、环境信息(紫外线强度)、地震波(三轴方向加速度)作为测量项目。在此基础上，选择了能够作为教材使用的性能良好的传感器，并对其进行了技术指标的选择。该观测系统由数据控制单元和三台带观测部的地震仪组成。数据传输假定通过有线系统的串口通信来完成。在与观测部的数据控制单元中安装了串口通信电路。为了固定，测震仪部分与主体分离。TH…将更多的地震数据通过模拟信号发送到主机。(2)试制和程序开发根据规范进行了电路设计和样机制作。控制单元的程序开发与硬件开发同步进行。WEB数据服务器采用现成的H8-MPU板卡，安装了网络操作系统。开发了服务器端软件，实现了观测数据的Web显示。(3)观测数据格式的审核制作了观测数据的Web格式。制定了监控系统的软件规范，并进行了程序开发。2.通过开发发现：(1)实现了易操作性和安装性、断电措施、免维护等。(2)我认为所开发的装置在学校等方面是有效的设置。观测点数据的推广和有线综合服务器是必要的。较少

1. Flow of research(1)Making of specificationThe kind, accuracy, data amount, and system of units, etc. were examined, and a weather information (temperature, humidity, illuminance, atmospheric pressure, wind direction, velocity of the wind, and rainfall), environmental information (ultraviolet rays strength), and the seismic wave (acceleration in the direction of tri-axis) of the observation data which was able to be used as a teaching material were assumed to be a measurement item. The selection of the sensor which had the performance which was able to be made a teaching material based on this and the specification were made. The observation system decided to be composed of data control unit and three seismographs with Observation Department. The data transfer was assumed to do by serial communications of the wired system. The serial communications circuit was installed in data control unit with Observation Department. To fix, the seismometry part was separated with the main body. Th … More e seismic data is sent to the main body by analog signal.(2)Trial manufacture and program developmentThe design of the circuit and the prototype were manufactured based on the specification. The program development of control unit was done at the same time as developing hardware. The Web data server adopted a ready-made H8-MPU board equipped with the network operating system. Software for the server which displayed the observation data in Web was developed.(3)Examination of observation Data FormatThe form for Web of the observation data was made. The specification of software which controlled the observation system was made, and the program development was done.2.Finding obtained by development(1)The achievement of the easiness of easy operativeness and the installation, the power failure measures, and maintenance free, etc is indispensable.(2)I think that the developed device is effective to set up in the school etc.The data of the observation place is generalized and the wired generalization server is necessary.
