摘要
为了解决水文测验工作中的泥沙采样问题，根据水下电流通信和数字脉冲编码调制原理，研制了四仓遥控悬移质采样器，实现了一次下探可采集1～4个样点的水样和无线遥控采样的目的，提高了泥沙采样的工作效率，降低了劳动强度，保证了采样的准确性，具有较高的自动化程度，为水文泥沙测验工作提供了有效的泥沙采样手段。本文介绍了四仓遥控悬移质采样器的组成结构、遥控通信原理及其在泥沙测验中的应用情况。
To solve the problem of sampling suspended sediment in hydrology test, a new four-container sampling instrument with remote control was developed. The instrument is based on the Pulse Code Modulation（PCM） theory and can collect 1 - 4 samples each time. The instruement has many advantages such as high efficiency, good accuracy, high automation degree, and low labor-consuming. This paper focuses on the intreduetion of the basic prineiph, structure, and application of the instrument.
