A monitoring system includes: an imaging sensor configured to sense a lighting device of the passenger conveyor to acquire image data; and a processing apparatus configured to process the image data, the processing apparatus being configured to include: a background acquisition module configured to acquire a background model based on sensed image data; a foreground detection module configured to compare image data sensed in real time with the background model to obtain a foreground object; and a working condition judgment module configured to perform data processing at least based on the foreground object to judge whether the lighting device is in a normal state. Then, a failure or an abnormal lighting state of the lighting device can be timely diagnosed so that maintenance is performed.
