    摘要： 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.

    摘要： A hydraulic excavator 1 working in fields includes a controller 2 for measuring a working time for each of an engine 32, a front 15, a swing body 13, and a travel body 12, storing measured data in a memory of the controller 2, and then transferring it to a base station computer 3 via satellite communication, an FD, etc. The transferred data is stored as a database 100 in the base station computer 3. The base station computer 3 reads the data stored in the database 100 for each hydraulic excavator, calculates a working time of a part belonging to each section on the basis of the working time of that section, and compares the calculated working time with a preset target replacement time interval of the relevant part, thereby calculating a remaining time up to next replacement of the relevant part and managing the scheduled replacement timing thereof. Thus, the appropriate scheduled replacement timing of parts can be determined even in a construction machine having a plurality of sections that differ in working time from each other.

    摘要： A controller 24 includes function generators 151, 152. The function generator 151 is set to have such a characteristic that as the detected value P.sub.N of a negative control pressure from a pressure sensor 21 is reduced, a first target tilting amount .theta..sub.N increases from a minimum value to a maximum value, and the function generator 152 is set to have such a characteristic that as the detected value P.sub.B of a control input (pilot pressure) for driving a boom cylinder 6 is increased, a second target tilting amount .theta..sub.B increases from a predetermined minimum value to the same maximum value as the above maximum value. Minimum one of the two target tilting amounts from both the function generators is selected, and a proportional solenoid valve 25 is driven based on the selected minimum tilting amount. This makes it possible to surely suppress an unwanted speed increase of a specific hydraulic actuator other than a boom cylinder, such as a swing motor 9, that would be caused when the tilting amount is controlled based on only the negative control pressure.

    摘要： In a region limiting excavation control system for a construction machine, a region where a front attachment (1A) is movable is set beforehand. A control unit (9) calculates the position and posture of the front attachment based on signals from angle sensors (8a-8c), calculates a target speed vector (Vc) of the front attachment based on signals from control lever units (4a, 4b), and modifies the target speed vector such that the target speed vector is maintained as it is when the front attachment is within the set region but not near the boundary thereof. A vector component (Vcy) of the target speed vector in the direction toward the boundary of the set region is reduced when the front attachment is within the set region near the boundary thereof, and the front attachment is returned to the set region and when the front attachment is outside the set region. As a result, the excavation within a limited region can be implemented efficiently and smoothly.
