    • A remote diagnostic system for remotely diagnosing and developing a dynamic system including a dynamic system being controlled by a first control system and a device model being controlled by a second control system. The device model simulates the dynamic system and inputs and corresponding outputs are recorded to test the control system and operation of the dynamic system. During operation the dynamic systems inputs and outputs are recorded. The dynamic system input and outputs may then be compared to the device model inputs and outputs to check the accuracy of the device model. The device model may then be updated based on the results of the comparison.
    • 一种用于远程诊断和开发包括由第一控制系统控制的动态系统和由第二控制系统控制的设备模型的动态系统的远程诊断系统。 设备模型模拟动态系统,记录输入和相应的输出以测试控制系统和动态系统的运行。 在操作过程中,动态系统输入和输出被记录下来。 然后可以将动态系统输入和输出与设备模型输入和输出进行比较以检查设备模型的准确性。 然后可以基于比较结果更新设备模型。

    • A mobile lift crane (10) comprises a carbody (12) having movable ground engaging members (14, 16). A rotating bed (20) is rotatably connected to the carbody such that the rotating bed can swing with respect to the ground engaging members. A boom (22) is pivotally mounted on a front portion of the rotating bed. A mast (28) is mounted at its first end on the rotating bed. A backhitch (30) is connected between the mast and a rear portion of the rotating bed. The crane (10) further comprises a movable counterweight unit, at least one hydraulic cylinder, and at least one arm pivotally connected at a first end to the rotating bed and at a second end to the hydraulic cylinder. The arm and hydraulic cylinder are connected between the rotating bed and the counterweight unit such that extension and retraction of the hydraulic cylinder changes the position of the counterweight unit compared to the rotating bed.
    • 一种移动式起重机(10)包括具有可移动的地面接合构件(14,16)的车体(12)。 旋转床(20)可旋转地连接至车体,使得旋转床可相对于地面接合构件摆动。 吊杆(22)枢转地安装在旋转底座的前部上。 桅杆(28)的第一端安装在旋转床上。 后桅(30)连接在桅杆和旋转底座的后部之间。 起重机(10)还包括可移动的配重单元,至少一个液压缸和至少一个臂,所述臂在第一端处可枢转地连接至旋转底座并且在第二端处可枢转地连接至液压缸。 臂和液压缸连接在旋转床和配重单元之间,使得液压缸的伸出和缩回相对于旋转床改变配重单元的位置。
