Example Embodiment

[0034] Hereinafter, embodiments of the passenger conveying equipment of the present invention will be described with reference to the drawings.

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

[0036] As shown in FIG. 1, in the passenger conveying device of the present embodiment, laser scanning sensors 1a and 1b are provided on the cover part of the passenger conveying device in and out part. The laser scanning sensors 1a and 1b are connected to the signal processing device 2, and the data from the laser scanning sensors 1a and 1b are received through the serial communication receiving and sending part 5 provided in the signal processing device 2, and the data is processed in the CPU 3 Then output the processing result to the interface part 6. The memory 4 stores the processing program of the CPU 3 and the like, and can record the obtained data. The output of the signal processing device 2 is sent to the ...

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...
