Abstract

The invention provides a control device for a passenger transporting apparatus, and a control method thereof, which can reduce the total consumed power of all escalators and suppress the adverse effect on the flow of the passenger using the escalators to be a minimum, in a building, department store, or the like having multiple escalators. The control method of the invention comprises determining the load (consumed power) state of each escalator, and reducing the speed of the escalator with little passengers. Accordingly, when the number of the passengers is in the predetermined heavy duty state, by means of suppressing the speeds of the other escalators, the total consumed power of all escalators is reduced, and the adverse effect on the flow of the passenger using the escalators is controlled to be a minimum.

Description

technical field [0001] The present invention relates to a control device and a control method of passenger conveying equipment for controlling passenger conveying equipment such as escalators and moving walks. Background technique [0002] In recent years, the requirement for energy saving of escalators has become higher and higher. For this reason, technical solutions aimed at reducing the power consumption of escalators when no one is using them have been proposed. As such a technical solution, there has been proposed a technical solution in which a passenger number detection device is installed on the escalator so as to perform speed control according to a change in the number of passengers. As the above-mentioned related technology, Patent Document 1 discloses an operation control method of an escalator, which grasps the number of passengers based on the power value, and divides the power value into two settings: a small number of passengers and a large number of passeng...
