为了研制和生产一种适合我国大量机帆渔船在浅海区使用的水平探鱼仪,在要求的探测距离下,我们除了考虑混响及水声干扰的影响外,设计中还主要考虑了要使仪器的体积小,重量轻,便于安装在机帆渔船或小型渔轮上,操作和维修方便,降低造价并着眼于国产元件进行生产,制造工艺简便等。换能器的结构与工作方式及研制的成败与上述目标的实现与否关系密切。 In order to develop and produce a horizontal fish finder that is suitable for use in a large number of Chinese sailing boats in the shallow sea area, in addition to considering the influence of reverberation and underwater noise in the required detection range, the design mainly considers Small size, light weight, easy to install in the machine sail fishing boat or small fishing vessel, easy operation and maintenance, reduce costs and focus on domestic components for the production, manufacturing process is simple and so on. Transducer structure and working methods and the success or failure of development and the realization of these goals or not.
