    摘要:

    可靠的回收系统是海洋仪器进行有效观测和获取数据的关键一环,其中仪器在海面上与科考船 之间的通信信标是回收系统中的重要组成部分。该文设计的低功耗海上仪器回收通信信标是一套可用于 海洋仪器回收的轻量化信标机——集成了全球定位系统(GPS)定位模块和 Lora 低功耗远距离通信模块, 浮出海面后可自动切换为待机模式。该系统在低功耗待机模式下理论待机时间长达 5 年,正常工作模式 下可连续工作不少于 48 h。仪器上浮后可以将位置信息发送至客户端,有效通信距离达到 7 km,并满足 9 000 m 水深的深海适用要求。功耗测试与通信测试表明,该设备具有功耗低、定位精度高、可靠性高、 通信距离较远的优点。

    Abstract:

    A reliable recovery system is crucial to marine instruments for effective observations and data acquisitions. The communication beacon between the instrument on the sea and the scientific research ship is a key part of the recovery system. The low-power marine instrument recovery communication beacon designed in this paper is a set of lightweight beacon machines that can be used for marine instrument recovery. The system integrates a global position system (GPS) positioning module and a Lora low-power long-distance communication module. The system can automatically switch to the standby mode while it float up. The system can work continuously for 48 h. Under the low-power standby mode, the theoretical standby time is over 5 years. Once the instrument floats up, the location information can be sent to the nearby ships. The effective communication distance can reach 7 km. The system can bear the pressure up to 9 000 m water depth. Power consumption test and communication test showed that, the proposed instrument has low power consumption, high positioning accuracy, high reliability, and long communication distance.
