Low-temperature drift detection system of high-speed rail roadbed settlement monitoring static level gauge
The invention discloses a low-temperature drift detection system of a high-speed rail roadbed settlement monitoring static level gauge, which comprises an air pipe, a liquid pipe, a data bus, a liquid storage device, a bin body, a datum point level meter, a measuring point level meter and an air pressure control device, the liquid storage device, the datum point level meter and the measuring point level meter are communicated through an air pipe and a liquid pipe, and reading of measuring data of all nodes is achieved through a data bus. The datum point level meter and the measuring point level meter each comprise a water pipe connector, an air pipe connector and an installation support. The air pressure control device is connected with an air cavity of the liquid storage device and comprises a compressible springback air bag, stepping motors, lead screws, round flange copper nuts, an air bag connector unit, an upper pressing plate and a lower pressing plate, one ends of the two lead screws are connected with the two stepping motors and fix the lower pressing plate, the other ends of the two lead screws are connected with the round flange copper nuts to fix the upper pressing plate, and the compressible rebound air bag is controlled. The device can greatly reduce the influence of the environment temperature change on the system measurement result, and can accurately monitor the measured object.
本发明公开了一种高铁路基沉降监测静力水准仪的低温漂检测系统,包括气管、液管、数据总线、储液装置、仓体、基准点物位计、测点物位计、气压控制装置，储液装置、基准点物位计、测点物位计由气管、液管连通并由数据总线实现对各节点测量数据的读取。基准点物位计与测点物位计均包括水管接头、气管接头、安装支架。气压控制装置与储液装置的气腔相连，包括可压缩式回弹气囊、步进电机、丝杆、圆法兰铜螺母、气囊接口器、施压上板和施压下板，将两个丝杆一端连接两个步进电机并固定施压下板，另一端连接圆法兰铜螺母固定施压上板，控制可压缩式回弹气囊。该装置可使环境温度变化对系统测量结果的影响大大降低，对被测物体实施准确监测。
