振弦式传感器电子标签管理系统的设计与实现

Design and Realization about Management System of Vibrating-wire Sensors′ Electric Tags

振弦式传感器性能参数离散性很大,出厂时必须单独标定,并将编号写在一个套管上作为标签套在每个传感器的电缆上。在应用中,由于人为因素以及受施工环境的影响,标签很容易磨损或丢失,从而导致传感器因参数不可知而成为废品。为此,设计了一个应用系统,将传感器相关数据写入E2PROM芯片,然后置入传感器内部,形成一个电子标签,这样,即使外套标签磨损或丢失,依然可以利用手持设备从电子标签中读出传感器编号和参数,解决了应用中的一大难题。

The function parameters of the vibrating - wire sensors have great discreteness respectively. When the sensors are produced, they must be marked individually. The numbers are written down on the thimbles as tags and then attach the tags to the cables which are elicited by sensors. However, in the application, because of the artificial factors and the influence of the construction environment,the tags are easy to be obliterated or lost,which induces sensors to become waste products on account of unknown parameters. Therefore, an application system is designed. The relative data of the sensors is written into E^2 PROM and then put EEPROM into the sensors, which forms the electric tags. So, under the condition of the tags obliterated or lost, the numbers and parameters of the sensors can be read from the electric tags by using the portable device, which settles a difficult problem.
