摘　　要：随着传感网络理论和技术的不断发展,对网络化传感器的开放性和互操作性提出了更高的要求,传感数据标准化描述正成为研究热点。提出了一种基于扩展SDP(Session Description Protocol)的传感数据描述协议SDDP(SensorData Description Protocol)。该协议以文本方式对传感器固有参数进行一定程度的定义,并用ABNF语言对其做了形式化描述,为网络化测控环境下传感器的互联和使用带来了方便。通过与在通信领域取得巨大成功的SIP协议结合,SDDP协议实现了网络化传感器与其它设备的高效互联。应用了RS232,OPC等接口标准来传输SDDP协议数据,并分析了其时间性能。实验表明SDDP具有较好的易用性和开放性,有助于形成传感器接口标准化。Sensor network, a new kind of distributed measurement and control system, has been developed rapidly with high requirements for openness and interoperability, and standard description of sensor data is becoming a popular re- search topic. The paper presented a kind of sensor data description protocol （SDDP） which was based on SDP （session description protocol）. SDDP defined some important parameters of sensors in a text-based way, and gave a formalization description for it in ABNF language, which offered convenience for connecting sensors in control-measurement system. Through cooperation with SDP, SDDP protocol can connect networked sensors more effectively. The experiment results indicated that SDDP-SIP has good real-time performance, handiness and openness.
