In the oil well's monitoring system, the information has the characteristics of diversity and complexity. this paper presents the oil well' s monitoring system based on Web Services. The data interface of the field devices are released in the form of Web Service, so data exchange of the different devices are changed into a standard data exchange that expressed as Web Service interface. This approach eliminates the heterogeneity of device interfaces, moreover it achieves a cross-language and platform independent and the integration of the field devices become easier to achieve.When single remote terminal is linked in LAN, the video server rates up to 25fps and can meet the general surveillance.%油井监控系统中的信息具有多样性、复杂性,为了解决不同信息、不同设备集成效率低的问题,使用Web Services技术将不同类型现场设备的数据接口以Web Service的形式发布,从而使远程监控终端与现场设备的数据交换变成了标准的Web Service方法调用;这种方法实现消除了不同类型现场设备接口的异构性,实现了设备集成的跨语言、跨平台特性,使得油井监控系统中温度、压力、流量以及视频监控等设备的集成变得容易;在局域网中、单个远程终端链接情况下,视频服务器速率达25fps,满足一般的监控要求.
