Problems solved by technology
At this time, the central point repeatedly appears and disappears irregularly, and multiple such phenomena occur at the same time, so the moving speed of each object to be detected cannot be accurately calculated
That is, it is virtually impossible to capture the movement of individual passengers with laser scanning sensors when crowded
In addition, in the conventional people detection device, the laser sensor head is arranged at a high place near the predetermined target area, and the laser sensor head arranged obliquely above is used to irradiate laser pulses from the front of the body toward the head, so it is not like transporting passengers. Laser scanning of the footsteps of passengers near the entrance and exit

PURPOSE: A congestion level detecting device and a passenger conveyor are provided to prevent conduction by outputting control commands based on the number and walking speed of users. CONSTITUTION: A passenger conveyor(1) comprises a platform bottom plate(4), an approach passage(6), and a scan-type distance sensor(7). The platform bottom plate is installed in each entrance and comprises a comb plate(5) in a step side of the passenger conveyor. An approach passage is installed in the half of the comb plate of the platform bottom plate and is formed to approach the platform bottom plate. The scan-type distance sensor is installed around the entrance and irradiates laser beam to a scanning zone including the platform bottom plate and the approach passage. The scan-type distance sensor is installed to see the steps of passengers; accumulates the distance of each measured angle; and outputs control commands based on the number of the passengers in the scanning zone and walking speed.

Description
technical field [0001] The present invention relates to a retention degree detection device for detecting the retention degree near an entrance, and to a passenger conveyor such as an escalator and a moving walkway provided with the retention degree detection device. Background technique [0002] In the passenger conveyor, when a user (passenger) gets off the running passenger conveyor at the entrance, if the person stays near the entrance, there is a possibility of a mistake and a fall. Therefore, in order to prevent such fall accidents, if the degree of stagnation near the entrance, that is, the crowded state of passengers can be detected, control commands such as an alarm and / or stop can be issued in advance. [0003] Conventionally, a safety device for a passenger conveyor has been proposed (for example, refer to Patent Document 1). The movement of the user on the plane coordinates, when the moving speed of the user measured by the laser scanning sensor (the information...
