MACHINE-POSITION-INFORMATION MANAGEMENT SYSTEM, CRANE, AND DATA MANAGEMENT APPARATUS

摘要

A machine-position-information management system is disclosed, which is capable of reducing the transmission and data management costs in management of the work positions of machines. In the machine-position-information management system for a crane, a transmission controller determines whether the crane has started work, based on a result of the detection by a work-state detector, and when determining that the crane has started work, the transmission controller outputs the position information acquired from a GPS sensor at this time to a data management unit from a remote communication system. The data management unit is configured to save the position information when the crane starts the work and to output the saved position information upon request for use.

主权项

1. A machine-position-information management system comprising:
a transmission controller configured to transmit position information of a machine to a data management unit at a remote location using a remote communication system, the position information being acquired from a positioning system, and the data management unit being configured to save the position information and to output the saved position information upon request for use, wherein; the machine includes a crane, and wherein the machine-position-information management system further comprising a work-state detector configured to detect whether the crane is disposed at a work position, thereby detecting whether the crane is in a work state, wherein the transmission controller determines whether the crane has started or ended work, based on a result of the detection by the work-state detector, and when determining that the crane has started or ended work, the transmission controller outputs the position information acquired from the positioning system at this time to the remote communication system.
