Abstract: A heating control apparatus and method for an escalator system or automatic walkway system, an escalator system and automatic walkway system including the heating control apparatus, and a computer-readable storage medium on which a computer program for implementing the method is stored. A heating control apparatus for an escalator system or automatic walkway system includes: memory; a processor coupled with the memory; and a computer program stored on the memory and running on the processor, the running of the computer program causes: A. obtaining ambient status and device status of the escalator system or automatic walkway system, the ambient status includes ambient temperature and ambient humidity; and B. generating a control command regarding a heater of the escalator system or automatic walkway system based on the ambient status and the device status.

Abstract: A passenger conveying device, including: an entrance, an exit, and a plurality of steps disposed between the entrance and the exit. A skirt guard panel is respectively disposed on two sides of the step, and the step is constructed to reciprocally move between the entrance and the exit along a path defined by the skirt guard panel. The step includes a tread, a tread guard panel is attached to each of two sides of tread, and the tread guard panel is located between the tread and the skirt guard panel. The tread guard panel includes two or more protrusions, each protrusion is constructed to protrude with respect to an upper surface of the tread, and a protrusion farther away from the tread has a larger protrusion height. The passenger conveying device of the present invention has the advantages of simple structure, reliable installation, and convenient maintenance.
