YZ-CCD型自动传高仪研制与测量方法研究
|
摘要
在大坝变形监测中都要遇到不同高程层面的高程传递问题,高程传递自动化监测系统无疑是解决不同层面高程传递的最佳解决办法。论述了自行研制并已投入应用的新型模具化制造的YZ-CCD型自动传高仪的原理,并简要介绍了其构成、技术指标等,特别对自动传高仪的测量方法及计算方法进行了初步研究。YZ-CCD型传高仪中的传感单元采用新型CCD光电器件,传感器的特点是无漂移、无摩擦,仪器较容易地解决了不同层面的高程传递问题,具有推广和应用价值。而且传高仪也可以很方便地与CCD型垂线仪、静力水准仪、引张线仪等仪器连成一个自动化变形监测系统。若将传高仪与坝顶布设的静力水准仪和廊道内布设的静力水准仪相结合应用,则可达到实时自动传递高程的效果。
In dam deformation monitoring,the hypsographic transmit automatic monitoring system is the best method to resolve the altitude measurement of different levels.The basic elements,machinery structure and technic parameters of YZ-CCD type automatic hypsometer are introduced in this paper. The measurement method and calculation formula are also presented.The sensor unit of YZ-CCD type automatic hypsometer,in which the CCD(charge coupled device) is used,has no excursion and friction in the work.Because the altitude measurement of different levels is settled,this kind of hypsometer has the very good prospects in economy and application.The YZ-CCD type automatic hypsometer can work together with other CCD deformation instruments,such as the pendulum system,settlement system and deflect meter.When the hypsometer is used with static level gages,which are installed on the top and base of the dam,the altitude data transmission can be realized in real time.
