Description

  The present invention relates to a passenger conveyor driving device for driving a passenger conveyor such as an escalator or a moving sidewalk.

Conventionally, passenger conveyors that improve safety by allowing children, elderly people and people with disabilities to get on and off with peace of mind connect an electric motor to a three-phase AC power source to drive an endless step, A power supply system with a power converter connected so that two different operating speeds can be selected between the three-phase AC power supply and the motor, and a time setting circuit that continuously operates at least the first floor for low speed operation Is provided. An operation panel for giving an operation command to the time setting circuit is provided in the vicinity of the entrance / exit, or is configured to perform low-speed operation in a preset time zone (for example, see Patent Document 1).

JP 2000-198653 A

  However, switching between high-speed operation and low-speed operation switches operation commands from the operation panel installed at the landing, or sets a timer to switch according to the time of day, so it is possible to switch the passenger conveyor due to external factors such as raining. There is a problem that it cannot be solved that the exit is crowded with passengers.

  An object of the present invention is to provide a passenger conveyor operating device that prevents a danger of being congested at an exit due to external factors such as rain.

  A passenger conveyor driving device according to the present invention is the passenger conveyor driving device that controls an inverter circuit that drives an electric motor that drives a passenger conveyor disposed so that the exit is located near the boundary between indoor and outdoor. A rain sensor that detects the rain that falls near the exit, a monitoring camera with a viewing angle near the exit and on the step, and an image recognition congestion that analyzes the images taken by each of the monitoring cameras and calculates the degree of congestion When the situation judgment circuit and the passenger conveyor are operating at steady speed, if it rains near the exit and the congestion level near the exit and on the step increases, the passenger conveyor should be slowed down slowly. When the passenger conveyor is in speed-controlled operation, if it rains near the exit and the degree of congestion increases both near the exit and on the steps, the passenger conveyor is gradually reduced. And and a control unit for controlling the inverter circuit so as to stop.

  The effect of the passenger conveyor operating device according to the present invention is that the rain sensor and the rain sensor are installed even when it is raining near the passenger conveyor exit located so that the exit is located near the boundary between the indoor and the outdoor. Based on information from the surveillance camera that monitors the mouth and on the step, the passenger conveyor operating speed is slowly decelerated, slowly accelerated, or stopped, so the number of passengers per hour that get off the exit by changing the passenger conveyor operating speed It is possible to prevent that many people gather near the exit and there is no place to go.

FIG. 1 is a schematic configuration diagram of a passenger conveyor provided with a passenger conveyor operating device according to an embodiment of the present invention.
The passenger conveyor driving device according to the embodiment of the present invention controls a motor 4 that drives an endless step to drive a passenger conveyor having a boundary between indoors and outdoors in the immediate vicinity of a passenger exit. .
The passenger conveyor driving device according to the embodiment according to the present invention determines whether or not it is raining from the signals of the rain sensors 1a and 1b and the rain sensors 1a and 1b whose output signals change when rain is attached to the surface. Rain judgment circuit 9, monitoring cameras 2a and 2b for photographing passengers on exits and steps, and image recognition congestion status judgment circuit for determining increase / decrease in the degree of congestion on exits and steps from images taken by surveillance cameras 2a and 2b 6, a control unit 7 for obtaining a passenger conveyor step control command and a voice guidance command according to the presence or absence of rain and the degree of congestion, an inverter control unit 5 for calculating a speed command value according to the control command, and an inverter for driving the motor 4 according to the speed command value Circuit 10, voice guidance device 8 for sending voice guidance content to directional speaker 3 according to voice guidance command, and voice guidance content Comprising a directional speaker 3 to broadcast.

The image recognition congestion situation determination circuit 6 captures images taken by the monitoring cameras 2a and 2b at a predetermined cycle. Then, the captured image is subjected to image analysis, and the current number of passengers photographed in the image is obtained and stored. In this way, the number of passengers per predetermined cycle is stored.
In addition, the image recognition congestion situation determination circuit 6 compares the obtained number of current passengers with the number of previous passengers obtained by taking in the previous time, and the degree of congestion is larger when the current number of passengers is larger. Determined to have increased. Since the surveillance camera 2a photographs passengers on the step, it is determined whether or not the degree of congestion on the step has increased from an image captured by the surveillance camera 2a.
Moreover, since the surveillance camera 2b images passengers at the exit, it is determined whether the exit congestion degree has increased from the image captured by the surveillance camera 2b.

The controller 7 varies the operation speed of the passenger conveyor according to whether it is raining, whether the exit congestion is increased, and whether the step congestion is increased.
When the passenger conveyor is operating at a steady speed and it starts to rain, a command is issued to slow down slowly when both the exit congestion level and the step congestion level increase. A command is issued to operate at a steady speed when at least one of them does not increase.
Conversely, when the passenger conveyor is operating at a steady speed and it is not raining, a command is issued to slow down slowly when both the exit congestion and step congestion increase, and the exit congestion or step A command is issued to operate at a steady speed when at least one of the congestion levels does not increase.

On the other hand, when the passenger conveyor is operated with speed control from the steady speed and it rains, a command is issued to slow down and stop when both the exit congestion and step congestion increase. A command is issued to maintain the current speed of the speed control when the degree of congestion at the exit is not increased and the degree of congestion at the step is increased and the degree of congestion at the exit is increased and the degree of congestion at the step is not increased.
On the other hand, if the passenger conveyor is operated with speed control from the steady speed and it is not raining, the current speed of speed control should be maintained when both the exit congestion level and the step congestion level increase. A command is issued so that the vehicle is slowly accelerated when at least one of the exit congestion degree or the step congestion degree does not increase.
