【摘要】 主要介绍了一种应用于安全线路巡检的智能化系统,它通过利用串行RS-232接口实现数据通信,将已存储于通信座内的现场采集的巡检数据安全可靠地传入到计算机中,采用ADO.NET对数据库的访问技术,把这些数据保存到企业建立的SQL Sever2000数据库中,然后按照事先约定的排班规则对这些巡检数据进行分析比较和处理,最后得到巡检结果,并将巡检结果汇总到数据库中,可以实现历史数据查询、数据结果统计、数据报表打印等功能。 文章着重描述了智能巡检系统的线路排班机制,并通过深入剖析排班规则与巡检数据之间的关系,阐述了如何利用现有的排班规则得出合理的巡检结果。同时给出了远程数据传输的模型和实现机制,介绍了数据通信双方应遵循的通信协议格式和数据传输的可靠性保障机制,而且还对基于调制解调的远程数据通信作了进一步的阐述。另外,结合企业数据库实例着重分析了ADO.NET的数据库访问机制,阐述了它的工作机理,并利用ADO.NET的工作机理提出了企业网络数据传输模型,给出了联结于广域网的企业数据库之间实现数据传输的解决方案。文章还对智能巡检系统的关键技术做了更详细的描述,分析了如何利用最新的数据库访问技术ADO.NET实现对数据库的快速访问和对不同类型的数据源中的数据的访问。最后,对智能巡检系统的安全进行了探讨,介绍了系统数据库的安全性以及系统安全保护的实现。更多还原

【Abstract】 An intelligent system applied to line-patrolling and line-checking has been described there. By using the serial interface of RS-232 to transfer, the data collected in the process of line patrolling and checking can be put into a database which has been built in the local computer. A new technology of accessing database, ADO.NET, has been used to put the data collected into the enterprise SQL Server database. When the data has been handled, a result analyzed to attain the enterprise management object can be gotten by a rule which has been built earlier. When it has been transferred into the database, an action of inquiry or making report forms can be made. And the printed function also can be achieved.The description of constructing the rules of making schedule is put on the first place. Through a deeply analyzing about the relationship between the rules and the data, an appropriate result can be attained by using the rules existed. And a model of network communication has been given there, as well as its mechanism of implement. A protocol which the both sides of sender and receiver must be lay on is presented, and the dependability of data transfer also has been described. A method of remote communication based on modem has been made a further introducing there. Connected with the enterprise database, ADO.NET’s mechanism of accessing database also has been carried out. With it another model of network communication has been figured out. And a method of how the patrolling and checking data can be transferred between the two enterprise’s databases distributing in different areas through WAN also has been given. At last, the key technologies associated with the intelligent patrolling and checking system are widely discussed there. A deeply analyzing of how to use AD0.NET to access the database and different database has been given. And the security of this system has been described; include the database security and the implement of system security protecting.更多还原
