Example Embodiment

[0020] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0021] like figure 1 As shown, the passenger conveying apparatus of the present embodiment has: a motor 1 for driving pedals, not shown, which are annularly connected to convey passengers and the like; an inverter 2 connected to the motor 1; and a control section that performs operation control 3; an overload detection section 3a which detects an overload state and outputs an output signal indicating the overload state; an alarm section 4 which is provided on the passenger conveying apparatus main body side for issuing an alarm; and a notification section 5 which is provided in the presence of an administrator. The duty room on duty is used to issue notifications. Among them, the overload detection part 3a is built in the control part 3, detects the overload state according to the inverter load information of the inverter 2, for example, and outputs an output si...

Abstract

The present invention provides a passenger conveying equipment which can more authentically release an overloading state and can prevent unlimited duration of light overloading state. The passenger conveying equipment is provided with the following components: an overload detection part (3a) which detects the overloading state and outputs an output signal that represents the overloading state; an alarm part (4) which sends out an alarm according to the output signal; and a control part (3) which performs operation control and outputs a first alarm instruction according to an output signal of the overload detection part, and furthermore the alarm part sends out the first alarm. Afterwards, when the output signal has output for first preset time, the control part outputs second alarm instruction and notification instruction, and the alarm part sends out a second alarm. Simultaneously the notification part notifies to a duty room. Afterwards, when the output signal is output for a second preset time period, the control part outputs an operation stopping instruction, thereby stopping operation of the passenger conveying equipment.

Description

technical field [0001] The present invention relates to a passenger conveying device, and more particularly, to a passenger conveying device capable of coping with the problem of overloading that occurs due to overloading of passengers. Background technique [0002] Generally, in passenger conveying equipment, an overload caused by overloading of passengers is detected, and when the overload is detected, the operation of the passenger conveying equipment is stopped in order to protect the motor. However, in conventional passenger conveyance facilities, there is a danger of causing passengers to fall because no notice is given when the operation is stopped. In addition, since the operation of the passenger conveying equipment is stopped every time an overload occurs, there is also a problem that operation efficiency and service quality are greatly reduced. [0003] To this end, solutions have been proposed in the prior art. For example, a technology has been proposed in Pate...
