摘要
计算机监控系统由实行监测控制的主机、监测仪器、执行机构与被监测的目标共同构成。通常采用总线结构连接各个设备的传感器和监控设备,各个管理站点的服务用局域网连接起来,形成一个内部网络。针对网络通信技术对传输数据及编程灵活性和安全性的局限、集成网络中不同平台之间通信的困难、远程监控系统在教室增加时产生大量监控数据的问题,研究提出面向对象技术的软件设计、数据库设计和索引使用策略、高代价查询的数据库策略;应用程序的空间和时间权衡、高效查询语句选择、数据备份及权限控制机制几方面的实现方案。
The system of computer monitoring and control is composed of the host of implementing monitoring and control,monitoring instruments,the actuator and the object being monitored. The sensors and the monitoring equipment of each device are usually connected by field bus structure; the service of each management site is connected by LAN; thus an Intranet is formed. On the limitations of network communications technology on data transmitting as well as the programming flexibility and security,the difficulties of communication between different platforms in an integrated network,and on the problems of producing a large number monitoring data by the increase of remote monitoring and control system in classrooms,this study proposes software design,database design and index use strategy,and database strategy of high cost query based on object- oriented technology; and it also puts forward the implementation scheme of balancing the space and time of application program,of choosing efficient query,and of data backup and access control mechanism.
