【摘要】：由多单位协作承担的“气候观测综合计量检定系统”课题,采用多变量联合控制模拟大气环境的方法,研究气象仪器、传感器在模拟环境状态下的数据质量、检测技术手段、探测仪器及传感器的设计效果、计量检定业务管理等内容,建立科学合理的仪器评估方法,为国民经济和政治军事提供更加强有力的气象保障。本论文以该课题需求为依据,设计并实现计量检定业务管理系统。论文首先对研究背景和国内外发展现状作了介绍,其次介绍了系统开发所用到的技术,包括RS232协议,MFC框架,B/S架构,MySQL数据库等技术,然后对本系统的需求进行了详细分析,并据此完成系统设计。最后详细描述了数据采集系统和数据管理系统的实现。数据采集系统主要用于实现对气象传感器输出数据的自动化采集,并以标准化格式存储。数据管理系统围绕检定数据的业务需求,用于对传感器检定数据的管理,有系统管理、数据管理、公告管理等模块。数据采集系统基于MFC框架开发,上位机利用MSComm控件控制计算机与数据采集器Keithley2000通信,通过发送相应的SCPI命令,使采集器按要求完成数据的自动化采集。上位机获取采集数据后,对其进行处理并以标准化格式写入相应的文件中。数据管理系统基于Django框架开发,采用B/S三层架构,有利于系统的可维护性和可扩展性。以用户权限为基础,实现对检定数据的录入、查询、修改和删除等一系列数据管理功能。
[Abstract]:The subject of "Comprehensive Measurement and Verification system for Climate observation", which is carried out by multi-unit cooperation, adopts the method of multi-variable joint control to simulate the atmospheric environment, studies the data quality of meteorological instruments and sensors under the simulated environment, and measures the technical means. The design effect of detecting instruments and sensors, the management of metrological verification and so on, and the establishment of scientific and reasonable instrument evaluation methods can provide more powerful meteorological support for national economy and political and military affairs. Based on the demand of this subject, this paper designs and implements the business management system of metrology verification. Firstly, this paper introduces the research background and the current development situation at home and abroad, and then introduces the technologies used in the system development, including RS232 protocol, MFC framework, B / S architecture, MySQL database and so on. Then, the requirements of the system are analyzed in detail, and the system design is completed. Finally, the implementation of data acquisition system and data management system is described in detail. The data acquisition system is mainly used to realize the automatic collection of meteorological sensor output data and to store it in a standardized format. Data management system is used to manage sensor verification data, such as system management, data management, announcement management and so on. The data acquisition system is developed on the basis of MFC framework. The upper computer controls the computer to communicate with the data collector Keithley2000 by using the MSComm control. By sending the corresponding SCPI command, the collector completes the automatic data acquisition according to the requirements. After the upper computer acquires the collected data, it is processed and written to the corresponding files in a standardized format. The data management system is based on the Django framework and adopts the B / S three-tier architecture, which is beneficial to the maintainability and expansibility of the system. Based on user rights, a series of data management functions such as input, query, modification and deletion of verification data are realized.
