低速作业时计程仪输出信号的必要改进

Improvement on log output signal during low-speed operation

计程仪是最基本的普航设备之一,它向许多设备输出接口信号。在运输船舶中,这些设备主要用于航行;而在海工等特种工程船舶中,这些设备主要用于辅助作业。所以,低速作业时计程仪输出信号需作必要改进。文中对计程仪设备在特种工程船舶应用时遇到的问题作了仔细的技术分析,并提出切实可行的解决方法。

As one of basic navigation facilities,log outputs interface signal to many other equipments.For shipment vessels,it is applied in navigation;while for offshore vessels,it is used for support operation.Therefore,the signal output during low-speed operation need to be improved.This paper analyzes the problems originated when log is applied on special-purpose engineering ships and proposes practical solutions.
