Method of detection of actual operating time of machinery deployed at construction sites, data collection and management system, and base station
First Claim
1. A method of detection of the actual operating time of machinery characterized by being applied to a system including:
- machinery each provided with a storage unit, a control unit receiving as input a quantitative machine status for work operations, and a first communications device enabling communication with an outside unit present at a distant location and deployed at a construction site; and
a base station provided with a second communications device enabling communication with an outside unit present at a distant location, a center server for identifying a serial number of machinery and transferring information with said control unit, and a database managed by said center server and storing information for each model of said machinery and information relating to the operation for each machinery;
wherein said control unit of said machinery and said center server of said base station are configured to be able to transfer information with each other through said communications devices and a communication line;
wherein said control unit measures the duration where a quantitative machine status satisfies a predetermined condition and stores it in the storage unit and transmits the measurement data of said duration to said center server of said base station; and
said center server receives the measurement data of said duration and calculates the cumulative operating time.

Abstract
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.
