摘要拖曳线列阵声呐（以下简称拖线阵）作为拖曳声呐中的一种，用线列阵型式，将一定间隔的水听器，放置到具有中性浮力的透声保护导管内。拖线阵的声学段前后，分别有仪表段、数字段、隔振段、稳定尾绳和拖缆等。拖线阵声呐在探测性能上，具有声阵孔径大、探测距离远、工作频率低，声阵配置不受舰体安放空间的限制等优势。由于我国海上运输事业的蓬勃发展以及海上设施的大规模建设，拖线阵拖曳绞车作为拖船的主要设备，得到了广泛的应用。 

为了适应现代机械对自动化的需要，本文提出一种电液控制的拖线阵拖曳绞车，将比例多路阀和可编程序控制器（PLC）应用于拖曳绞车的控制系统。通过合理的设计和选择，该设计不但提高了拖曳绞车的可靠性、可维护性以及灵活性，而且延长了绞车的使用寿命，缩短了绞车的开发周期。于此同时本次设计的绞车系统提高了拖曳控制水平，改善了拖曳运行的操作性能，使的操作更加人性便捷。50895

Abstract Towed line array sonar (hereinafter referred to as the towed linear array) as one of the towed sonar, and array type with lines, to a certain interval of hydrophone, placed in a neutral buoyancy entrant acoustic protection. Towed line array acoustic before, during and after the period of the meter, digital section respectively, isolation period, and stable tail rope and towing and so on. Towed line array sonar on the detection performance, with large acoustic array aperture, detection distance, low working frequency, acoustic array configuration is not restricted by hull put space etc advantages. Due to the rapid development of our country Marine transportation enterprise and offshore facility of large-scale construction, towed line array as tugboat towing winch main equipment, has been widely used.

In order to meet the need of modern machinery for automation, this paper proposes a towed line array towing winch, electric hydraulic control proportional cult-way valve and programmable controller (PLC) is applied to the towing winch control system. Through the reasonable design and selection, the design not only improves the reliability and maintainability of the towing winch and flexibility, and prolongs the service life of the winch; shorten the development cycle of the winch. At the same time the design improves the towing winch system control level, improve the operating performance of towing operation, make the operation more convenient and Human nature.

 This topic according to the structure characteristics of the electro hydraulic control winch, in-depth analysis of the composition of electro-hydraulic proportional control system, established the pump motor control of the hydraulic winch hydraulic system; write the control algorithm based on PLC. This paper mainly analyzes the towing winch electric hydraulic control system hardware design and software design, research and winch electro-hydraulic proportional control design based on PLC is put forward the implementation of the plan, finally the research content of this paper is summarized.

Key words: electric hydraulic servo control; Proportional cult-way valve; PLC; winch
