基于CAN总线开发了一套适应大型结构健康监测的信息采集、传输与预处理的传感器总线技术。为了使传感器总线具有信息共享与互操作的功能，在传感器总线中嵌入了开放与连接对象的操作规则，并将基于概率距离的数据存储策略嵌入传感器总线数据采集系统的应用层中。利用传感器总线开发的数据采集与数据存储系统的仿真结果表明，系统性能和存储效率是稳定可靠的，传感器总线系统为长期结构监测提供了高效的数据采集系统和途径。

A system for data acquisition and information preprocessing and transmitting for large complex structure damage monitoring was developed based on the field sensorbus. For sharing and cooperating the information coming from the sensorbus, the opened and linked object technique was embedded into the sensorbus. The strategy of saving data grounded on probability distance was developed and implanted into the application layer of data acquisition. The simulation of the sensorbus showed that the speed and efficiency of the sensorbus were reliable and precise. The result demonstrates that sensorbus is a useful tool and fundament for long term monitoring of large structure.
