摘要：【中文】本发明的作业管理系统高精度地推定电梯作业的作业人员的行动历史。追踪实施电梯作业的作业人员的行动历史的作业管理系统(1)包括：作业人员所携带的智能设备(300)、以及能与智能设备(300)通信的中心(400)。在该作业管理系统(1)中，中心(400)的基准值校正指令部(408)在电梯作业过程中作业位置所确定的多个特定的作业点的每个时刻，将与该作业点相关的现场信息以及基准值校正指令一起发送至智能设备(300)，智能设备(300)的测定值处理部(传感器值处理部(304))每当接收到基准值校正指令时，使用现场信息及测定部(气压传感器(302))在当前时刻的测定值，计算基准点在当前时刻的基准值，并更新现有的基准值。 【EN】The invention provides an operation management system which can estimate the action history of an operator in elevator operation with high precision. An operation management system (1) for tracking the action history of an operator who performs elevator operation comprises: a smart device (300) carried by the worker, and a center (400) capable of communicating with the smart device (300). In the operation management system (1), a reference value correction command unit (408) of a center (400) transmits field information related to a plurality of specific operation points specified by operation positions during elevator operation to an intelligent device (300) together with a reference value correction command at each time of the operation points, and a measurement value processing unit (sensor value processing unit (304)) of the intelligent device (300) calculates a reference value of a reference point at the current time and updates an existing reference value using the field information and a measurement value of a measurement unit (air pressure sensor (302)) at the current time each time the reference value correction command is received.
