Problems solved by technology

Therefore, for example, when you want to acquire image information in an outdoor environment exposed to direct sunlight, the image information will be lost in a state exposed to direct sunlight during the day, in a state illuminated by the setting sun at dusk, or in a state with a small amount of light at night. produce large discrepancies, and thus may have great difficulty in recognizing images

Embodiment Construction

[0034] Embodiments of the passenger transfer facility of the present invention will be described below with reference to the drawings.

[0035] FIG. 1 is a schematic configuration diagram showing an embodiment of a passenger conveying facility of the present invention.

[0036] As shown in FIG. 1 , in the passenger conveyor of this embodiment, laser scanning sensors 1a, 1b are provided on the cover portion of the entrance and exit of the passenger conveyor. These laser scanning sensors 1a, 1b are connected to the signal processing device 2, and the data from the laser scanning sensors 1a, 1b are received through the serial communication receiving and transmitting part 5 arranged inside the signal processing device 2, and the data are processed in the CPU 3 Then output the processing result to the interface part 6. The memory 4 stores processing programs of the CPU 3 and the like, and can record obtained data. The output of the signal processing device 2 is sent to the passen...

Abstract

The invention provides a safety device for a passenger transporting apparatus, and a safety control method thereof. A laser scanning sensor (1a, 1b) is arranged near the exit of the passenger transporting apparatus to detect the movement of the passengers at a plane coordinate through the scanning of the laser scanning sensor. When the moving speed of the passengers is lower than a specified value, a voice prompt for prompting attention is generated by a speech synthesis device (11) and a loudspeaker (12a, 12b); when the jam of the passengers is lasted for a long time, a control inverter installation (8) generates frequency and voltage to reduce the speed of a drive motor (9) or stop the same. Thereby, under the states of direct sunshine by day, sunset shine at dusk, and less light at night, the moving speed of the passengers can be accurately detected to form the safety device.

Description

technical field [0001] The invention relates to a safety device and a safety control method for passenger conveying equipment such as escalators and electric passages. Background technique [0002] As a prior art, for example, in Patent Document 1, etc., it has been proposed to install a camera on the upper part of the passenger conveying equipment, and use image recognition technology to detect the situation when passengers step in and the technical solutions of congestion and other states. [0003] Patent Document 1: JP-A-2000-115750 [0004] Image recognition technology is based on image information acquired by a camera, which is obtained by capturing light and converting it into information. Therefore, for example, when you want to acquire image information in an outdoor environment exposed to direct sunlight, the image information will be lost in the state exposed to direct sunlight during the day, in the state illuminated by the setting sun at dusk, and in the state w...
