摘要当今，船舶行业快速发展，回转式液压起货机是船舶行业用于装卸货物的一种起 重设备。回转式液压起货机是一个复杂系统，不能直接在外部进行观察。当内部发生 不合理操作时，会造成设备损坏。为了预防不合理操作，本论文基于 ARM 嵌入式开 发系统以 MiniGUI 移植和开发界面为主，研究了起货机的监控系统以及其界面设计。79791

首先，在系统硬件设计方面，以天嵌科技的 TQ2440 为开发板，介绍开发板的主 要硬件如电源电路、串口接口电路、JTAG 接口。熟悉开发板的基本组成、工作线路 图并完成监控系统硬件设计。

其次，在软件设计方面，采取 Linux 作为嵌入式操作系统，完成 Linux 系统在嵌 入式设备上的移植，并重点研究 MiniGUI 在开发板上的移植和监控系统界面设计。 将监控系统直接显示在开发板液晶屏幕上，使得本系统能够直接观测监控信息。

最后，在各个模块正常工作的前提下，进行系统测试。经测试表明：该系统能实 现起货量、起货机大臂角度两个状态参数的实时检测与显示，并可根据起货量等级进 行报警或停机保护处理。

Abstract Nowadays, with the rapid development of boats and ships, the rotary hydraulic winch is a lifting device for loading and unloading cargo in the shipping industry。  Rotary hydraulic is a complicated system, which can not directly observe on the outside。 when the internal unreasonable operation occurs, it will cause the damage of the equipment。 In order to prevent the unreasonable operation, this paper based on ARM embedded development system, mainly depends on MiniGUI transplantation and interface design, to study the monitoring system and design the interface。

Firstly, in the aspect of the system hardware design, based on TQ2440 plate which support by EmbedSky, this paper introduces the development board of hardware such as power supply circuit, serial interface circuit, JTAG interface。Then studying with the basic composition, working circuit diagram and completing monitoring system hardware design。

Secondly, in the aspect of software design, adopt the Linux as an embedded operating system, complete Linux system on the transplant of embedded devices, and focus on MiniGUI transplantation and monitoring system。 The monitoring and control system directly displayed on the board LCD screen, so that this system can be directly observed。

Finally, under the premise of normal work of the various modules, then perform system testing。 The test shows that the system can realize the two requirements of the volume and Crane angle detection at the same time。 According to the information to alarm or stop running。
