Design and Application of an Eccentric Semi-Submersible Buoy Type Automatic Surface Water Temperature Acquisition Device

本文设计了一种偏心半潜浮筒式表层水温自动采集装置，该装置主要包括偏心浮筒及无线接收单元两部分：偏心浮筒主要用来测量和发送表层水温数据，其设计可确保水温采集装置不受漂浮物及河流水位变化的影响，同时可在一定程度上防止漂浮物撞击；无线接收单元安装在控制室内，接收来自偏心浮筒发送过来的表层水温数据并与水情遥测终端接口，将水温与其他水情数据发送到中心站。偏心浮筒内的数据采集单元采用低功耗设计，可保证使用半年内不更换电池。该水温自动采集装置，在北碚水文站成功应用，为大水位变幅的水文站提供了一种表层水温自动采集方法。
This paper elaborates a design of automatic surface water temperature acquisition device with an ec-centric semi submersible buoy type. The device mainly includes two parts: eccentric buoy and wireless receiving unit. The eccentric buoy is mainly used to measure and send surface water temperature data. Within the eccentric buoy design, the water temperature acquisition device will not be affected by floating objects and changes of river level and can partially avoid impact from floating objects. The wireless receiving unit is installed in the control room and connected with the hydrological telemetry terminal which will send the water temperature and other hydrological data to the central station after receiving the surface water temperature data from the eccentric buoy. The data acquisition unit in the eccentric buoy uses low power consumption which can guarantee six months durable time without changing the battery. The automatic water temperature acquisition device has already been applied in Beibei hydrological station successfully, which provides a method for automatic collection of surface water temperature for shore cable hydrological station with large water level variation.
