Abstract

PROBLEM TO BE SOLVED: To provide a human body sensor which can easily and highly accurately detect users only on the main body side of itself with no wiring facility required for some of equipements by using a reflective sensor having a limited measurement range set for detection of users within a ticket examination path. SOLUTION: The reflective sensor 3a consists of a light emitting element 3a1 which radiates a light beam and a light receiving element 3a2 which generates a current on reception of the light beam. Thus, the sensor 3a can radiate the light beam in the direction orthogonal to the passing direction of a thicket examination path P. Then, the element 3a2 can receive only the light beam that is sent from the element 3a1 and reflected on an adult user or a child user existing in the path P, that is, can receive the light beams only in its own measurement range of the path P. Owing to use of such sensor 3a, it's not required to prepare some of equipements at its main body side opposite to the path P and accordingly no wiring facility is required for those equipments.

[0008]

However, since the above-mentioned conventional human detection device uses a photoelectric element type human detector, a part of the human detector is installed also on the opposite main body side. In addition, some of the devices have the trouble of requiring wiring, require adjustment of the optical axis with the opposing body, and frequently clean the light emitting and receiving surfaces. There was also a problem in terms of maintenance such as necessity. In order to solve such problems, it is also possible to irradiate the ticket gate with ultrasonic waves or infrared laser beams, receive reflected waves, and calculate and detect the users in the ticket gate from the time difference between transmission and reception. Although it has been proposed, the arithmetic processing circuit is complicated and expensive, and requires a long processing time. In addition, when such an ultrasonic wave or an infrared laser beam is used, there is a problem in detection accuracy that a user in an adjacent ticket gate is erroneously detected.

The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to eliminate the need to install a part of the device on the opposing main body, and therefore, to provide the device with a part thereof. It is an object of the present invention to provide a human detection device which can detect a user with high accuracy and simply by using only its own main body side without requiring the above wiring equipment.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a front view of an automatic ticket gate to which the human detection device according to one embodiment is applied, viewed from the ticket gate passage P side, and FIG. 1B is a right side view thereof.
The same components as those in the conventional example shown in FIG.

In the drawing, reference numerals 3a to 3h denote reflection sensors, of which the reflection sensors 3b, 3d and 3g are provided at positions which divide the length of the sensor mounting bar a 'into approximately three equal parts. , The remaining reflective sensors 3a, 3c, 3e,
Reference numerals 3f and 3h are provided at positions above the ticket gate P on the side of the main body a, which divide the ticket gate P approximately into four equal parts. The reflection type sensors 3b, 3d, and 3g provided on the sensor mounting bar a 'are provided for detecting an adult similarly to the conventional human detection device, and are provided on the body a. Sensors 3a, 3c, 3 located at
e, 3f and 3h are for detecting children. In addition, a pair of central human detectors 3d and 3e are provided at predetermined intervals along the passing direction of the ticket gate passage P. This is for detecting the passing direction of the user according to the detection order, similarly to the conventional human detector.

Since the reflection type sensors 3a to 3h have the same configuration, the reflection type sensor 3a will be described below with reference to FIG.

, And a commercially available distance-limited reflective sensor can be employed.

The detection signals detected by each of the reflection sensors 3a to 3h are configured to be input to a controller C comprising a microcomputer for controlling the main body a.

This controller C is, as shown in FIG.
System program and RA stored in ROM 4
It has a central processing unit (CPU) 6 that performs an entry / exit calculation process using the working data stored in M5.

The CPU 6 is connected via an I / O unit 7
In the course of transporting the ticket taken in from the slot 1 to the outlet 2 or to the collection box (omitted in FIG. 1) in the main body a, predetermined processing such as data reading, writing, punching, or printing is performed. A card handler (omitted in FIG. 1) 8;
A door driver 9 for driving and controlling the doors D1 and D2 is connected to a sensor amplifier 10 for processing signals received by the reflection sensors 3a to 3h. The I / O unit 7 is connected to a display unit for providing guidance to the user, but is omitted here.

In the automatic ticket gate having the above structure, the slot 1

On the other hand, an invalid ticket such as an expiration of the validity period
In the case of a judgment NG or a billless person, the billless person is the reflection type sensor 3d, 3 at the center position of the ticket gate passage P.
The structure is such that the door D1 is closed at the time when the detection is made at e.

When a user is detected by the reflection type sensors 3a and 3b on the entrance side of the ticket gate passage P, it is determined that the user has entered the ticket gate passage P, and the user enters the ticket gate passage P. When it is detected by the reflective sensors 3g and 3h on the exit side, and thereafter, the detection is stopped, it is determined that the user has advanced from the ticket gate passage P. Further, when the signal is detected by the reflection type sensor 3c between the center and the entrance of the ticket gate P or the reflection type sensor 3f between the center and the entrance of the ticket gate P, the user is pointed at the intermediate point.

According to the above configuration, the human detection device is a reflection type sensor having a limited measurement range. Therefore, only the user in his / her own ticket gate passage is detected with high accuracy, that is, by eliminating the influence of disturbance light. be able to. Moreover, since it is not necessary to mount the equipment on the opposite main body side, it is possible to not only have an advantage such that wiring equipment is unnecessary, but also, as shown in FIG. The sensor mounting bar a 'of the main body a on the side can be omitted, and the field of view of the attendant B can be widened.

In addition to the above-mentioned reflection type sensors 3a to 3h, a pyroelectric sensor capable of detecting infrared rays emitted from a user is provided so that an object such as a trunk can be distinguished from a user.
