摘要： Elevator components can be equipped with an electronic information plate. The electronic information plates are associated with a particular electronic information plate that can store different properties of the associated component. The content of each electronic information plate is read manually or automatically and transmitted to a controller. The controller analyzes the received content and launches a predetermined action if the content indicates a need for maintenance.

摘要： The present invention discloses a multi-channel impact-resistant intelligent-constant-deceleration hydraulic braking system, and relates to the field of safety braking control for mine hoist systems. A technical point of the braking system is that the braking system includes a braking circuit formed by a constant-deceleration hydraulic system, a constant-deceleration electrical closed-loop control system, and a detection and feedback apparatus. The constant-deceleration hydraulic system is provided with N+1 independent complete oil return channels, where N is a positive integer greater than or equal to 3. The oil return channels are disposed in parallel to form parallel independent braking circuits, that is, are “multi-channel” and do not have a “common output point”. The oil return channel includes a backup oil source, an electro-hydraulic signal conversion and amplification component, an operating mode switching apparatus, and an execution component that are sequentially connected. The oil return channels include one backup channel and N working channels. Functions such as constant-deceleration braking, impact and vibration limiting, rope slip prevention, derailing prevention, and overwinding prevention can be safely and reliably achieved when a mine hoist system normally stops, performs operation braking or performs safety braking, thereby greatly reducing an accident rate.

摘要： An elevator system (1) including at least one refuge space (7, 8) and at least one light curtain (9). The at least one light curtain (9) is configured to detect at least one object in the at least one refuge space (7, 8) and produce at least one safety signal (21) indicating the presence of the at least one object in the at least one refuge space (7, 8). The system can be used to improve the safety in the at least one refuge space (7, 8) in the event that the usual safety procedures have either failed or not been followed.

摘要： An elevator control device recognizes a destination floor of a user from a voice of the user input to a voice input device, registers a voice car call corresponding to the recognized destination floor, generates stop floor information including a stop floor at which a car stops before the car arrives at the destination floor after the registration of the voice car call, and performs, as a voice announcement that follows the generated stop floor information, any one of a first announcement for notifying of the stop floor in order of floors at which the car stops and a second announcement for notifying of how many floors the car stops at before arriving at the destination floor.

摘要： An audio system for an elevator includes two or more speaker cabinets arranged inside a suspended ceiling fixed to a ceiling board of a car of the elevator, an input device to which sound content radiated to an inside of the car from each of the two or more speaker cabinets are input, and a sound field control device configured to conduct phase control and reverberation time control for the sound content and thereby cause a sound wave based on the sound content to be radiated from the speaker cabinet to the inside of the car. Each of the speaker cabinets includes a casing arranged inside the suspended ceiling, and a speaker unit arranged inside the casing and having a radiation surface that radiates the sound wave.
