The purpose of this invention is to provide an elevator rope tension checking device and an elevator rope tension checking system that can monitor changes in rope tension regardless of car position. An elevator rope tension checking device (18) comprises a storage unit (183), a generation unit (184), and a determination unit (185). The storage unit (183) stores learning data indicating sound or vibration measured during a learning operation by a measuring device (17) that measures the sound or vibration generated when an elevator rope (10) impacts a sheave (3a). The generation unit (184) generates reference data on the basis of the learning data stored in the storage unit (183). The determination unit (185) determines changes in the rope tension on the basis of differences between the reference data and diagnosis data indicating the sound or vibration measured by the measuring device (17) during a diagnosis operation.
本发明的目的在于提供能够与轿厢的位置无关地监视绳索张力的变化的电梯的绳索张力确认装置以及电梯的绳索张力确认系统。电梯的绳索张力确认装置(18)具备存储部(183)、生成部(184)以及判定部(185)。存储部(183)存储学习数据,该学习数据表示在学习运转期间由对电梯的绳索(10)碰到绳轮(3a)时所产生的声音或振动进行测定的测定装置(17)所测定的声音或振动。生成部(184)根据存储在存储部(183)中的学习数据生成参照数据。判定部(185)根据表示在诊断运转期间由测定装置(17)所测定的声音或振动的诊断数据与参照数据的差分来判定绳索张力发生了变化的情况。
