A device serves for determining the speed of a passenger-transporting system. The device includes an arrangement of auxiliary elements and a sensing device. The arrangement of the auxiliary elements rotates, in a manner corresponding to a movement of the passenger-transporting system. The sensing device can sense whether an auxiliary element is, or is not, located at a certain sensing location. The auxiliary elements are of a first configuration type and a second configuration type. The sensing device can sense whether an auxiliary element is of the first configuration type or of the second configuration type. Furthermore, the sensing device can assign an auxiliary element of the first configuration type and an auxiliary element of the second configuration type to one another such that the direction of rotation can be determined from the order in which the auxiliary elements are sensed.

The present invention relates to the field of passenger conveyor technologies, and provides a monitoring system of a passenger conveyor and a monitoring method thereof. In the monitoring system and detection method of the present invention, a monitored object of the passenger conveyor is sensed by using an imaging sensor and/or a depth sensing sensor to acquire a data frame, and the data frame is analyzed by a processing apparatus to monitor whether the monitored object is in a normal state. The monitored object may include a landing plate, a step, a barrier used in a maintenance and repair working condition and/or a step speed, and the like.

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 control device adapted to be connected to a conveyor system having a drive motor, a motor control unit which provides a motor control signal to the drive motor and a motor speed sensor adapted to output a motor speed signal to the motor control unit. The control device comprises: a motor speed alteration unit adapted to intercept the motor control signal and to provide a modified motor control signal to the drive motor so as to cause the motor speed to increase or decrease by a speed change value from a first motor operating speed to a target motor operating speed; and a feedback unit adapted to intercept the motor speed signal and to provide a scaled motor speed signal to the motor control unit based on the intercepted motor speed signal, the scaled motor speed signal indicating to the motor control unit that the motor speed has not been increased or decreased from the first motor operating speed by the speed change value.
