A method and system is discussed for detecting distances between passengers walking onto escalators and moving sidewalks or travellators and for providing alerts to the passengers when minimum social distancing between the passengers is not being maintained.

The present invention provides a speed detection device and a speed detection method for a handrail of a passenger conveyor, and belongs to the technical field of passenger conveyors. A distance from the speed detection device provided by the present invention to a surface of a detected handrail is centimeter-scale or below centimeter-scale, wherein the speed detection device comprises a light source part, an imaging sensor and an image processing part. The speed detection device and the speed detection method provided by the present invention can accurately detect to obtain speed information of the running handrail, and the speed detection device is easy to install and maintain.

A power supply circuit of a passenger conveyor converts includes an electrolytic capacitor and a control power supply device configured to supply an electric power to a charging circuit configured to charge the electrolytic capacitor. A storage battery is disposed between a converter and an inverter in parallel with the electrolytic capacitor. When an operation of the passenger conveyor is stopped in response to a key operation, the power supply to the control power supply device is shut off. When the operation of the passenger conveyor is resumed in response to a key operation, a DC electric power charged in the storage battery is supplied to the inverter, to thereby allow the passenger conveyor to resume the operation.

There are provided measures for performing a configuration control in relation to an elevator, an escalator and automatic doors in a remote manner. Such measures exemplarily comprise determining a status of a component of said control apparatus, detecting whether a change with respect to said component has occurred based on said status, defining configuration parameters for said component, if it is detected that said change has occurred, and initiating transmission of said configuration parameters to said control apparatus.
