Abstract

<P>PROBLEM TO BE SOLVED: To provide a passenger detection device for an escalator capable of being easily added to an existing escalator without relying upon the structure of a handrail platform. <P>SOLUTION: Load sensors 11A, B, C, D, E, and F are installed in a preset detection range on the rear surface of a footboard 4. When any of them functions, it is assumed that passengers are present to detect all passengers. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a passenger detection device for an escalator or a moving sidewalk.

  As a device of this type for detecting a passenger without obstructing the flow of the passenger, a method of detecting a passenger by embedding an optical sensor in a railing boarding / alighting part is known (see Patent Document 1).

  The conventional escalator passenger detection device will be described with reference to FIGS. The same is true for moving walkways.

  Each of the ends of the balustrade boarding / unloading section 6 is filled with optical sensors 11LA, RA each composed of a pair of light emitters / receivers so that the projection lines R1, L3 of the respective optical sensors 11LA, RA intersect on the boarding / exiting plate 4. .

  A plurality of pairs of optical sensors such as left and right (11LA and 11RA, 11LB and 11RB, 11LC and 11RC, etc.) are provided to cover the detection ranges R, C, and L at the entrance and exit to detect all passengers getting in. .

As shown in FIG. 4, passengers approaching the boarding / lowering plate 4 from the building floor 3 trying to get into the escalator are respectively in the regions R before and after the point where the projected lights R1 and L3 from the left and right optical sensors 11LA and RA intersect. It is detected and detected as a passenger only when the left and right light sensors are activated simultaneously. When detected in this way, it is linked to the operation circuit of the escalator.
JP-A-6-87592 (paragraphs 0012 to 0014, FIGS. 1 and 2)

  In the escalator passenger detection device described above, an optical sensor is embedded in the balustrade boarding / exiting part, but when adding to an existing escalator, processing of the balustrade boarding / exiting part occurs, requiring a lot of work time. Become. Recently, for the purpose of saving installation space and improving the design, there are many structures having a balustrade boarding / exiting portion that is very narrow.

  In view of the above, an object of the present invention is to make it easy to add to an existing escalator regardless of the structure of the balustrade boarding / exiting portion.

  In order to achieve the above object, the present invention is configured such that a load sensor is installed on the back surface of the boarding board, detects that a passenger is on the boarding board, and the signal and the operation circuit of the escalator are linked. A plurality of load sensors are arranged to cover the range determined by the boarding / alighting plate.

  Since it is not necessary to bury the railing boarding / alighting part, the present invention can be installed without impairing the design, and functions can be easily added to existing escalators or moving walkways.

  The escalator passenger detection device of the present invention will be described based on the embodiment shown in FIGS.

  As shown in FIG. 1, load sensors 11 </ b> A, 11 </ b> B, 11 </ b> C, 11 </ b> D, 11 </ b> E, 11 </ b> F are installed in a predetermined detection range on the back surface of the boarding / alighting plate 4 at a predetermined distance from the boarding / alighting plate 4. The presence / absence of a passenger is detected by aging of the distance between the boarding / alighting board 4 and each sensor when boarding.

  As shown in FIG. 2, passengers walking on the boarding board 4 from the building floor 3 trying to get into the escalator are detected by the load sensors 11A, 11B, 11C, 11D, 11E, and 11F installed in the detection ranges F and B. Detect and detect as a passenger when any one operates. When detected in this way, automatic operation or variable speed operation is performed in conjunction with the operation circuit of the escalator.

  Since a passenger is detected without being embedded in the railing entrance / exit, as in the past, it is possible to cope without depending on the structure of the railing entrance / exit.

  Further, since the passenger plate always passes when getting into the escalator, there is no restriction on the detection area in the height direction from the floor surface.

Furthermore, since it is possible to deal with only the passenger plate part, it is possible to easily deal with existing escalators without impairing the design.

  In this embodiment, the case where a load sensor is used is described, but the same effect can be obtained even when a strain sensor is used.

It is a side view of the lower floor boarding / alighting part by this invention. FIG. 2 is a plan view of FIG. 1 (a diagram showing a detection range of a sensor). It is a perspective view of the conventional lower floor boarding part. FIG. 4 is a plan view of FIG. 3 (a diagram showing a detection range of a sensor).
