The invention provides a safety confirmation system and a safety confirmation method, which can more reliably detect unsafe actions of maintenance workers and reduce false alarm and missing alarm. The present invention is provided with: a first transmitter (501) provided to an external opening key (401) for opening a landing door; a second transmitter (502) provided to a hook part (402) of the fall prevention tool; a reception unit that is carried by a maintenance worker and that receives radio waves transmitted by the first transmitter (501) and the second transmitter (502); and a control unit that measures the received signal strength of the received radio waves. After the control unit detects that the received signal strength from the first transmitter (501) has decreased to a predetermined ratio with respect to an initial value measured at the start of the maintenance work, the control unit controls the second transmitter (502) during a period in which the received signal strength of the radio waves from the second transmitter (502) has not decreased to the predetermined ratio with respect to the initial value. An alarm for urging hooking of a falling prevention tool is alarmed.
本发明提供一种安全确认系统以及安全确认方法,能够更可靠地检测维护作业人员的不安全的行动,减少误报、漏报。具备:第一发送机(501),其设置于用于打开层站门的外部打开钥匙(401);第二发送机(502),其设置于坠落制止用器具的钩部(402);由维护作业人员随身携带的接收部,其接收第一发送机(501)以及第二发送机(502)发送的电波;以及控制部,其测定接收到的电波的接收信号强度。控制部在检测到来自第一发送机(501)的接收信号强度相对于在维护作业开始时测定出的初始值降低到预定的比率之后,在来自第二发送机(502)的电波的接收信号强度相对于初始值没有降低到预定的比率的期间,使催促坠落制止用器具的钩挂的警报鸣响。
