The present disclosure discloses a system and method for measuring safety clearance between the steps and skirt panels of an escalator and positioning hidden dangers and, which improves the working efficiency of the detecting personnel and reduces labor intensity; the system and method of the present disclosure has high accuracy, and eliminates the detection error caused by manual observation and the sense of responsibility, thus helping the detecting personnel to comprehensively detect the hidden dangers to minimize the escalator safety accidents caused by such hidden dangers; and its accurate hidden danger positioning function can help the maintenance personnel to carry out maintenance and adjustment faster. Therefore, the present disclosure is of great significance to the safe operation of the escalator and the personal safety of the passengers, and plays a positive role in promoting the development of the whole quality supervision.

Power is recovered from an escalator or a moving walkway as the step orbits an endless track on rollers. A generator is connected to a roller orbiting the track. A battery backup is provided. The power is used for emergency lighting on the step, and for data transmission. Advertising and messages are displayed on a dynamic video screen mounted on the step. The apparatus is mostly contained within the escalator step. Information is communicated wirelessly to a remotely located central control station and back to the step, so as to display information in real time and to update advertising while the escalator is in operation. The central control station also monitors performance parameters. The visual display can include LED lighting.

A display system is provided with a display device; the display device including: a light source configured to emit light; and a light guide element configured to guide incident light from the light source; the light guide element including: an emission surface configured to output incident light; and a plurality of light focusing portions configured to change the path of the incident light toward the emission surface, causing the light output to converge toward a convergence point or convergence line outside the light guide element or to radiate from a convergence point or convergence line outside the light guide element and thereby form an image outside the light guide element. The display device presents information as an image, e.g., as a stereoscopic image.

A method for monitoring a conveying system with a monitoring device includes recording a signal pattern progression in relation to a functional unit of the conveying system. A reference signal progression is stored in a database as is a correlation data set for the reference signal progression, the correlation data set including instants or time segments in the reference signal progression and reference to the functional unit. The reference is linked to each instant or time segment, the recorded signal pattern progression is compared with the reference signal progression by a processing unit, and in the event of deviation between the signal progressions an entry in the correlation data set belonging to the reference signal progression is determined by the processing unit on the basis of an instant or time segment of such a deviation, and the functional unit referenced there is output as a cause.

Systems and methods are provided for monitoring one or more conveyance devices, such as elevators and escalators. A server obtains maintenance data, inspection data and performance data about a given conveyance device a web portal. At least a portion of this information is in a first format. The server reformats this portion of information into a second format using a mapping table, outputting reformatted data. The server populates a graphical user interface (GUI) with the reformatted code events. The GUI is accessible by another computing device over the Internet.

An escalator system includes a pit having an access cover plate, a detector indicating when the access cover plate is open and when it is closed, and a user interface which is located in said pit and which in an active state provides the escalator system with control signals controlling the operation of the escalator and which in a passive state does not affect the operation of the escalator. In order to improve the safety of the escalator system the escalator system is configured to stop movement of the escalator if the detector indicates that the access cover plate is closed while the user interface is in the active state.

A sensor system for controlling operation of an escalator arranged on a landing plate at the exit of the escalator includes a plurality of sensors arranged over a landing area of the landing plate. Each sensor is disposed at predetermined intervals with respect to the width direction along the width between two balustrades and the length direction along the moving direction of the escalator, and is configured to detect a predetermined pressure so as to obtain a transition of ON/OFF states in response to a load presence.
