    • A maintenance system of a hydraulic excavator (11) is provided with a maintenance monitoring device (21), a maintenance management server (12) for managing trouble information and operating information for each working machine, a model information server (13), and a service personnel mobile terminal (14) connected to one another through the Internet (15). When trouble occurs in the hydraulic excavator, the maintenance system (21) transmits trouble information to the maintenance management server (12), and the maintenance management server (12) transmits information on occurrence of trouble to the mobile terminal (14) and displays it on a display unit. This system manages the maintenance manuals and other data for each model in a model information database separate from the maintenance database and correlates the two databases based on the model data.

    • The present invention is applied to a system comprised of large number of hydraulic excavators 1 deployed at construction sites and a base station 16. Each hydraulic excavator 1 is provided with a storage unit (memory 402), a control unit (CPU 401) for executing the work operation and receiving as input a quantitative machine status relating to the work operation, and a communications device 42. The base station 16 is provided with a communications device 16a, a management server 17 for identifying the serial number of the hydraulic excavator 1 and transferring information, and a database 18 for storing various information. The control unit of the hydraulic excavator 1 and the management server 17 of the base station 16 transfer information. With this system configuration, the control unit measures the duration during which the quantitative machine status satisfies a predetermined condition and stores it in the storage unit and transmits the measurement data of the duration to the management server 17 of the base station 16 conditional on the power input key being in the off position, while the management server 17 receives the measurement data of the duration and calculates the cumulative operating time. Further, the quantitative machine status and various event data stored in the storage unit of the hydraulic excavator 1 are sent to the base station 1, while the management server of the base station 16 stores the quantitative machine status and various event data in the database 18 by a predetermined format.
    • 本发明应用于由在施工现场部署的大量液压挖掘机1和基站16组成的系统。每个液压挖掘机1设置有存储单元(存储器402),用于执行的控制单元(CPU401) 工作操作和接收作为输入与工作操作相关的定量机器状态以及通信设备42.基站16设置有通信设备16a,用于识别液压挖掘机1的序列号的管理服务器17 和传送信息,以及用于存储各种信息的数据库18。 液压挖掘机1的控制单元和基站16的管理服务器17传送信息。 利用该系统配置,控制单元测量定量机器状态满足预定条件的持续时间并将其存储在存储单元中,并将持续时间的测量数据发送到基站16的管理服务器17,该功能以功率为条件 输入键处于关闭位置,而管理服务器17接收持续时间的测量数据并计算累积操作时间。 此外,存储在液压挖掘机1的存储单元中的定量机器状态和各种事件数据被发送到基站1,而基站16的管理服务器将定量机器状态和各种事件数据存储在数据库18中 按预定格式。
