WORKER APPROACH NOTIFICATION SYSTEM
To provide a worker approach notification system capable of preventing an excessive alarm.SOLUTION: The present invention periodically changes magnetic field strengths of magnetic field signals 120A to 120D generated from magnetic field generators 21A to 21D, includes information including magnetic field ID, the magnetic field strength, and tag ID in information transmitted and received between an RFID tag 40 and a tag information receiving device 22, and detects a position of a worker carrying the RFID tag 40 based on the information. Further, an area for performing detection and approach notification of the RFID tag 40 is determined according to the work state of a hydraulic excavator 1, and the detection result is notified to an operator based on the determined content.SELECTED DRAWING: Figure 2
【課題】過度な警報を防止することができる作業員接近通知システムを提供すること。【解決手段】磁界発生装置２１Ａ〜２１Ｄから発生する磁界信号１２０Ａ〜１２０Ｄの磁界強度を周期的に変更し、磁界ＩＤと磁界強度とタグＩＤとを含む情報をＲＦＩＤタグ４０とタグ情報受信装置２２の間で送受信する情報に含ませ、その情報に基づいてＲＦＩＤタグ４０を形態した作業員の位置を検知する。また、ＲＦＩＤタグ４０の検知および接近通知を行うエリアを油圧ショベル１の作業状態に応じて決定し、その決定内容に基づいて検知結果をオペレータに通知する。【選択図】 図２
