    • A calculating portion 7a calculates a distance from the tip end of a front device to an interference prevention area, and a detection line 7m detects a moving speed of a boom 1. If the tip end of the front device comes close to the interference prevention area when the boom 1 is moving upward, control is made such that, while continuing to move the boom 1 upward, a control gain calculating portion 7h and a multiplier 7i cooperatively calculate a target speed of an arm in the arm dumping direction (interference avoiding direction) corresponding to the boom-up speed, and an input limit value calculating portion 7c, an adder 7j and a minimum value selecting portion 7f cooperatively control the arm to move in the interference avoiding direction relative to a vehicle body. Interference avoidance control enabling the tip end of the front device to be moved smoothly along the vicinity of a boundary of the interference prevention area is thereby effected and the front device can be prevented from interfering with the vehicle body without reducing the maneuverability and the working efficiency.
    • 计算部7a计算从前部装置的前端到防干扰区域的距离,检测线7m检测吊杆1的移动速度。如果前部装置的前端靠近防干扰区域 当吊杆1向上移动时,进行控制,使得在继续向上移动吊杆1的同时,控制增益计算部分7h和乘法器7i协同地计算臂倾倒方向上的臂的目标速度(干扰避免方向 ),并且输入限制值计算部分7c,加法器7j和最小值选择部分7f协调地控制臂相对于车身在干扰避免方向上移动。 从而能够使前端装置的前端能够沿着防干扰区域的边界附近平滑移动的干扰避免控制,并且可以防止前部装置与车身干涉而不会降低机动性和工作效率 。

    • A method and system for managing a construction machine and processing apparatus therefor includes a controller 2 mounted on a hydraulic excavator 1 working in fields. An operating time for each of an engine 32, a front 15, a swing body 13 and a travel body 12 is measured and stored in a memory of the controller 2. The measured data is transferred to a base station computer 3 and stored in a database 100 inside the base station computer 3. The base station computer 3 reads, per hydraulic excavator, the data stored in the database 100 and then prepares and outputs a distribution graph of the number of operated machines with respect to the working time (engine running time) of the hydraulic excavator. While looking at the distribution graph, a machine maker estimates the number of hydraulic excavators to be renewed and estimates the sales quantity of hydraulic excavators, thereby setting up a production plan of hydraulic excavators.
    • 一种用于管理建筑机械及其处理设备的方法和系统,包括安装在在田间工作的液压挖掘机1上的控制器2。 发动机32,前15,摆动体13和行驶体12的运转时间被测量并存储在控制器2的存储器中。测量数据被传送到基站计算机3并存储在 基站计算机3内的数据库100.基站计算机3每液压挖掘机读取存储在数据库100中的数据,然后准备并输出相对于工作时间的操作机器数量的分布图(发动机运行 时间)的液压挖掘机。 在查看分布图时,机器制造商估计要更新的液压挖掘机的数量,并估计液压挖掘机的销售量,从而制定液压挖掘机的生产计划。
