Abstract

PURPOSE:To make it unnecessary to use a handrail-like frame body by arranging object detecting sensors directing fixed positions on the way of a passage in the down direction from the upper part to detect distances up to the object on the upper part of the passage to detect the height of the object passing the passage. CONSTITUTION:Distance sensors 21 to 23 are arranged on the ceiling just above the passage. The distance sensors 21 to 23 corresponding to respective object detecting sensors consist of distance definition type reflective photoelectric sensors or the like and point out the fixed position on the way of the passage from the upper part of the passage to detect the distances up to the object. Since the height of the sensors 21 to 23 are fixed, an object with a fixed height can be detected in accordance with their detecting result. Consequently, the handrail-like frame body can be omitted.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to automatic ticket gates installed at ticket gates in stations and the like.

(b) Prior Art The structure of a conventional automatic ticket gate is shown in FIGS. 5(A) to 5(C). (A) is a top view, (B) is X-X in (A)
(C) is a front view.

In the figure, 100a and 100b are automatic ticket gate units, respectively, and these two units 10Qa and 100b
are paired together to form one automatic ticket gate. Note that 101b is a unit on one side of another adjacent automatic ticket gate. The automatic ticket gate unit 100b has a ticket insertion slot 1.
, a winding outlet 2 and traffic blocking fields 5b, 6b are provided.

Further, the automatic ticket gate unit 100a is similarly provided with a ticket insertion slot 3, a roll exit 4, and a traffic blocking area 5a (not shown in the figure), 6a. The area between 100a and 100b is used as a passage, and when passing to the left in the figure, the ticket insertion slot 1 and winding exit 2 are used, and 5a and 5b are used as doors for blocking passage. In addition, when passing to the right in the figure, the ticket insertion slot 3 and the winding exit 4 are used, and 5a
, 5b are used as doors for blocking traffic.

Furthermore, the automatic ticket gate unit 100a shown in FIG.
100b is provided with a plurality of sensors for detecting the state of passage of people and objects. In the same figure, LOb~19b
are light receivers of transmission type photoelectric sensors, and opposite to this, the automatic ticket gate unit 100a has light transmitters 10a to 10a.
19a (not shown in the figure) is provided. Here, 10.16 is an entrance detection sensor, 15.19 is an exit detection sensor, 11 is an entrance side entrance detection sensor, and 14
12.13.1 can also be used as an exit side entry detection sensor.
7 and 18 are respectively used as central detection sensors.

Sensors 10-15 are provided on the main body side of knees 1-7 100a, 100b, whereas sensors 16-19 are provided on handrail-like frames 7a, 7 that protrude above the unit main body.
b. The height of the handrail-like frames 7a and 7b is provided to detect the height of the person (object) passing through the ticket gate. Specifically, all four photoelectric sensors 12°, 13, 17, and 18 in the center are on (detecting an object).
The object is counted as a child or baggage by turning on and turning off only the photoelectric sensors 12 and 13, and the direction of passage is determined by turning them all off. The determination is made based on the on/off timing of the other sensors and the four central sensors.

(C) Problems to be solved by the invention However, in such conventional automatic ticket gates,
Because it is necessary to detect the height of an object passing through the passageway, a handrail-like frame is provided. (1) The handrail-like frame gives a feeling of psychological pressure to people passing by.

(2) The handrail-like frame may become an obstacle, and luggage carried over the shoulder or the like may collide with it when passing.

(3) Since the mounting height and shape of the handrail-like frame are constant, the shape and installation method of the automatic ticket gate body are limited, and there are also significant design constraints.

There were other problems.

The purpose of this invention is to solve these conventional problems, and to make it possible to detect the height of an object (person, object) passing through a passage without using a conventional handrail-like frame. The purpose is to provide automatic ticket gates.

(d) Means for Solving the Problems The present invention provides an automatic ticket gate having a means for detecting the height of an object passing through the passageway, which is directed from above to below at a certain position in the passageway, and the height of the object passing through the passageway is oriented downward. It is characterized by being provided with an object detection sensor that detects distance.

(e) Function In the automatic ticket gate of this invention, the object detection sensor is
It points from the top of the passage to a certain point in the middle of the passage and detects the distance to the object. Since the height at which the object detection sensor is provided is constant, an object at a constant height can be detected based on the detection result of the object detection sensor. Therefore, the conventional handrail-like frame becomes unnecessary.

(f) Embodiment FIG. 1 shows the structure of an automatic ticket gate which is an embodiment of the present invention. The figure (A) is a top view, and (B) is the X-
A side view in the X direction, and (C) a front view. In the figure 1
00a and 100b are automatic ticket gate units, respectively, and these two units 100a and 10'Ob form a pair and constitute the main part of one automatic ticket gate. In addition, 1
01b is one unit of another adjacent automatic ticket gate. Similar to the conventional example shown in FIG. 5, the automatic ticket gate unit 100b is provided with a ticket insertion slot 1, a roll number exit 2, and traffic blocking areas 5b and 6b. Automatic ticket gate unit 100a
Similarly, there is a ticket insertion slot 3, a roll number exit 4 and a traffic blocking field 5.
a (not shown in the figure) and 6a are provided. Further, the automatic ticket gate unit 100b is provided with a plurality of light receivers 10b to 15b of transmission type photoelectric sensors, as shown in FIG. The automatic ticket gate unit 100a is provided with light transmitters 10a to 15a (not shown in the figure), which are transmission type photoelectric sensors, facing the automatic ticket gate unit 100a. Here, sensor 10 is an entrance detection sensor, 11 is an entrance side entrance detection sensor, and 1
2.13 is used as a center detection sensor, 14 is used as an exit side entrance detection sensor, and 15 is used as an exit detection sensor.

As shown in Fig. 1 (B) and (C), three distance sensors 21 and 2 are installed along the passage of the automatic ticket gate on the ceiling directly above the passage.
2 and 23 are provided. Each of these distance sensors corresponds to the object detection sensor according to the present invention, and is, for example, a distance-limited reflective photoelectric sensor.

This device integrates a light beam irradiation section and a light receiving section such as a two-split photodiode, and uses a triangulation method to detect reflected light from within a certain distance. As shown in FIG. 2B, this distance sensor detects an object within the detection range of the sensor and within a distance L from the ceiling. Therefore, objects whose height from the floor does not have a H type groove are not detected.

The distance sensor 21 performs entrance detection together with the transmission type sensor 10, the distance sensor 23 performs exit detection together with the transmission type sensor 15, and the distance sensor 22 performs exit detection together with the transmission type sensor 12.
Performs central detection together with 13.

FIG. 2 is a block diagram of the control section of the automatic ticket gate. C.P.
U40 is in charge of controlling the entire automatic ticket gate. ROM41
A processing program for the CPU 40 is written in advance. The RAM 42 has an area for temporarily storing the on/off state of each sensor and counting the number of people passing by. The transport mechanism 43 is a mechanism for transporting the inserted ticket along a predetermined route, and the transport control circuit 44 controls the transport. The magnetic head 46 reads or writes magnetic data recorded on the ticket being conveyed, and the read/write control circuit 47 controls the successive output or writing of data.

5.6 is a traffic blocking field, and the door opening/closing control circuit 49 performs opening/closing control thereof. The distance sensors 21 to 23 are sensors provided on the top surface of the automatic ticket gate unit as shown in FIG. 1, and the distance sensor control circuit 51 performs distance detection control of each distance sensor. The light transmitter 10a, the light receiver 10b, . . . the light transmitter 15a, the light receiver 15b, etc. are transmission type photoelectric sensors as shown in FIG. 1, and a transmission type sensor control circuit 53 performs detection control thereof. Each of the above control circuits is connected to the pass line via interface circuits 45, 48, 50, 52 and 54, respectively.

Next, the processing procedure of the automatic ticket gate control section will be explained according to the flowchart of FIG.

First, the transmission type photoelectric sensor 10 and distance sensor 21 perform entrance detection, the transmission type photoelectric sensor 15 and distance sensor 23 perform exit detection, the transmission type photoelectric sensor 11 performs entrance side approach detection, and the transmission type photoelectric sensor 11 performs exit side approach detection. By detecting the state of each sensor of the type photoelectric sensor 14,
Check the entry and passing conditions for automatic ticket gates. Furthermore, if there is an approach, the direction is memorized (nl).

Next, the states of the transmission type photoelectric sensor 12, 13 that performs center detection and the center distance sensor 22 are read, and if all three sensors are in the on state, all three sensors are then in the off state. The number of people (adults) passing through is counted up (n2 to n6). If only the transmissive photoelectric sensors 12 and 13 turn on, but the sensors 12 and 13 turn off without turning on the central distance sensor 22, the passing object is assumed to be a small person or luggage, and the number of people passing is counted. No upload is performed (n7→n1).

In the embodiment, a so-called distance-limited reflective photoelectric sensor is used as the object detection sensor, but a distance-measuring sensor that directly measures the distance to the object may also be used. An example of this case is shown below.

The configuration of the device is almost the same as that shown in Figure 1, but here the sensor 2 is installed on the ceiling side of the central detection section.
As the second sensor, a distance measuring sensor is used.

The processing procedure of the automatic ticket gate control section is shown in FIG. First, the transmission type sensor 10 and distance sensor 21 perform entrance detection, the transmission type sensor 15 and distance sensor 23 perform exit detection, and the transmission type sensor 1 performs entrance side entrance detection.
By detecting the state of each sensor of 1 and the transmission type sensor 14 that performs entrance detection on the exit side, the state of entry into and passage through the automatic ticket gate is confirmed. If there is an approach, the direction is stored (n20). Next, the states of the central transmission type sensors 12 and 13 are read, and if both are turned on, distance measurement is performed using the distance measuring sensor 22 (
n21→n22). This distance measurement is repeated until both the center transmissive sensors 12 and 13 are turned off (
n23 → n22), when both the transmissive sensors 12 and 13 are turned off, calculate the average value of the distance l obtained in n22 (n24), and then calculate the average value of the distance l obtained in n22. The average height h is calculated (n25).

Here, H is the mounting height of the distance measuring sensor as shown in FIG. 1(B). The height h of the object obtained in this way
It is determined whether or not is higher than a predetermined reference height Htyp (n26). Here, Ht)Fp is a threshold value for determining adults and dwarfs, as shown in FIG. 1(B). n2
If 6 is YES, the passing object is regarded as an adult and the number of passing persons is counted up (n'27). Otherwise, the passing object is regarded as a small person or luggage, and the number of passing persons is not counted up (n26→n20).

Note that as the distance sensor or distance measuring sensor, a sensor that uses traveling waves such as ultrasonic waves or microwaves and detects the distance based on the time until the arrival of the reflected wave from the object can also be used.

(Effect of the Phantom Invention According to this invention, an object detection sensor is provided at the top of the passage, pointing from above to downward at a certain position in the passage, and detecting the distance to the object. Since the height of the object is detected, the following effects can be obtained.

+1) Since there is no need for a handrail-like frame, there is no psychological pressure on those passing through, and ticket gates can be checked smoothly.

(2) Since there are no obstacles, it is possible to pass through with relatively large items slung over one's shoulders.

(3) The automatic ticket gate main body is not subject to design limitations due to the provision of a handrail-like frame, and the degree of freedom in terms of usage and design is increased.
