The invention belongs to the technical field of underwater sound velocity data measurement, and discloses an autonomous lifting type underwater sound velocity measuring instrument, a measuring system and a measuring method. The autonomous lifting type underwater sound velocity measurement method comprises the following steps: measuring reflection echo time delay at a fixed distance by using an underwater sound velocity measurement device, and calculating real-time underwater sound velocity data by using a pulse time method according to the measured reflection echo time delay by using a CPU of a main control core. According to the data transmission mode, high-cost and low-efficiency varnished wire transmission is abandoned, instead, the Wi-Fi wireless communication technology is used, after data acquisition, the system automatically floats to the water surface to conduct wireless data transmission with receiver equipment such as an unmanned aerial vehicle and a deck unit, and therefore low-cost accurate measurement of the ocean sound velocity profile in a specific area is completed. According to the invention, the circuit board is accurately customized according to the required functions, and components with reasonable sizes and proper power are selected for device assembly and arrangement, so that miniaturization and low power consumption can be realized.

    本发明属于水下声速数据测量技术领域,公开了一种自主升降式水下声速测量仪、测量系统及测量方法。所述自主升降式水下声速测量方法包括:利用位于水下的声速测量装置对在固定距离处的反射回波时延进行测量,主控核心的CPU对测量的反射回波时延利用脉冲时间法计算出实时的水下声速数据。本发明的数据传输方式摒弃了高成本低效率的漆包线传输,转而使用Wi‑Fi无线通信技术,在数据采集后系统自主上浮到水面与无人机、甲板单元等接收机设备进行无线数据传输,从而完成特定区域海洋声速剖面的低成本精确测量。本发明根据所需功能精确定制电路板以及选择合理尺寸、恰当功率的元器件进行器件组装与布放,可实现小型化、低功耗。
