A maintenance device () includes, for example, a clock (), a clock (), a selection unit (), and a recording unit (). The clock () outputs time information. The clock () outputs time information. The selection unit () selects at least one of the clock () or the clock () as a clock to be used. The recording unit () records elevator information by adding time information from the selected clock to the elevator information. The selection unit () selects the clock to be used according to the content of the elevator information to be recorded by the recording unit ().

Maintenance device and elevator device

A monitoring device () is provided at a building () in which an elevator () is provided and communicates with a center via an IP network (). The monitoring device () includes a communication unit () and a selecting unit (). The communication unit () can perform wireless communication in a plurality of communication modes. The selecting unit () selects a connection mode on the basis of a first evaluation value and a second evaluation value. The communication unit () transmits voice data and state data indicating a state of the elevator () to the center in the connection mode.

Monitoring device and monitoring system

An elevator preventive maintenance system capable of helping, when an abnormality of an elevator is predicted to occur, a concerned person needing no countermeasure information to grasp information quickly and easily, and helping a concerned person needing countermeasure information to react to the abnormality quickly and precisely. The system includes: a prediction section configured to predict an abnormality of an elevator to occur, based on abnormality prediction information; a storage section configured to pre-store concerned person information relating to the elevator; a communication section configured to transmit abnormality occurrence prediction information to concerned person in the case the abnormality is predicted to occur.

Elevator preventive maintenance system

A retrieval system includes a first storage unit (), a second storage unit (), a selection unit (), an extraction unit (), and a calculation unit (). The second storage unit () stores a plurality of signal tables. The selection unit () selects a first use table from the plurality of signal tables. The extraction unit () extracts a value of each signal registered in the first use table from the first signal group and the second signal group. The calculation unit () calculates a similarity level between the first signal group and the second signal group.

Retrieval system and monitoring system

An elevator system is provided, in which when a telephone in an information center receives an emergency call using an analogue public telephone network from an interphone of an elevator, a monitoring person in the information center can confirm information of the elevator which transmits the emergency call while responding to the emergency call by the telephone. To this end, the elevator system includes: means configured to add, as an identification voice signal, identification information to a call voice signal input to an intercom provided inside each of cars of elevators, the identification information enabling the elevator in which the intercom is installed to be specified; means configured to transmit, with an analog signal, the call voice signal to which the identification voice signal is added; means configured to reproduce the call voice signal included in the transmitted analog signal; means configured to extract the identification information from the identification voice signal included in the transmitted analog signal; and a monitoring terminal configured to acquire, from a server configured to store information on the elevator specified by the identification information in association with the identification information, information on the elevator associated with the identification information extracted from the identification voice signal and to display the acquired information.

Elevator system

An elevator system stores, in a server, information on an elevator installed in a building that is communicably connected to a data center in which the server is installed, the building and the data center being communicable independently via a first network and a second network, respectively, wherein the building includes: an information collection device configured to collect information on the elevator; a sorting device configured to determine which of the first network and the second network is to be used as a transmission path via which the information on the elevator collected by the information collection device is to be transmitted to the data center; and a communication device configured to transmit the information on the elevator collected by the information collection device to the data center via the transmission path determined by the sorting device.

Elevator system for monitoring a state of an elevator installed in a building

A display system is provided which determines an effective image area by automatically detecting a boundary between the effective image area and a non-image area created owing to the difference between the pixel numbers of the camera image sensor and television signal, to thereby display the images on a monitor by adjusting a display size and position suitable for the effective image area, whereby an inappropriate display size and position are avoided from being set while a lighting device for illuminating a camera's field of vision is off. The display system receives a signal notifying about activation of the lighting device from the lighting controller that provides on/off control of the device; the system then determines the effective image area if the device is on, and does not if it is off.
