Method and system for the traceability of a tool vibratory charge and tool for use with the system

摘要

The system is intended to block the tool operation for an operator holding a badge the authorized working time of which is over. The system comprises: the operator badge, comprising a storage memory for the working time carried out by the operator and a communication unit; the tool, comprising an accelerometric sensor and a housing for control and vibratory traceability comprising a communication module, arranged to exchange data with the operator badge and means for blocking the tool operation. For the vibratory charge traceability of the tool, in the tool, the accelerations experienced by the tool while operating and its corresponding working times, forming traceability data, are measured; the traceability data in the tool are saved; the traceability data are transmitted to an operator personal badge.

1. A method of tracing vibration exposure of an operator of a tool that generates vibrations while operating, said method comprising:
measuring, in the tool, accelerations generated by the tool while operating and working times, which correspond to the accelerations, and forming traceability data; saving the traceability data in the tool; transmitting the traceability data to a badge carried by the operator and detached from the tool; recovering the working times from the badge and related to the operator; and then calculating a compensatory rest time related to the operator (i) to block the operation of the tool when an authorized working time overflows and (ii) to permit the operation of the tool when the authorized working time does not overflow, wherein the tool is only operable with the badge.
