Automatic ticket checker

Abstract

PROBLEM TO BE SOLVED: To provide a highly reliable automatic ticket gate with no erroneous detection and erroneous determination by positively tracking a position of a person by sensors. SOLUTION: A plurality of sensors 1-16 are linearly arranged in a passage direction, and each sensor interval y is set so that adjacent sensors detect one person at the same time. A plurality of sensors including at least the adjacent sensors is considered as one group, and a status corresponding to a sensor position is assigned to each group. In a state wherein all of the plurality of sensors in one group are outputting detection signals, it is determined that a person is positioned in a status of the group, and the position of the person is managed on a real time basis by tracking transition of the status.

Description

technical field [0001] The present invention relates to an automatic ticket checking device installed at railway stations and the like. Background technique [0002] Figure 18 It is a schematic side view showing an example of a conventional automatic ticket gate. The automatic ticket checking device 100 has a pair of upper and lower sensors 101a, 101b installed on the entrance side (right side in the figure), a pair of upper and lower sensors 102a, 102b installed in the center, and an upper and lower pair of sensors installed on the exit side (left side in the figure). A pair of sensors 103a, 103b. These sensors are composed of light sensors, and when the upper and lower sensors are blocked from light at the same time, it is detected that a person has reached the position. 104 is a door on the entrance side, and 105 is a door on the exit side. [0003] When a passenger puts a ticket into the ticket opening (not shown) of the automatic ticket gate 100 and passes through, ...

AI Technical Summary

Problems solved by technology

As a result, even if a passenger with a normal ticket is put in, the door 105 will be closed and the inappropriate phenomenon of prohibiting passage will occur.

Second, when people pass through the central part in a state of contact with each other, or pass through in a state of contact between people and luggage, since the sensors 102a and 102b in the central part are in a light-shielding state at the same time, it is one time. The device side will judge that one person has passed, and the ticket count remains (2-1=1), and as a result, one passenger can pass without a ticket

Third, when a passenger performs complicated movements such as wandering back and forth in the passage of the automatic ticket checking device 100, since the sensor cannot track the person correctly, it may be detected that someone enters the exit side, or a second passenger enters the entrance side. and so on

Fourth, since the detection of people is only performed by the light shielding and light transmission of the sensor, there is a possibility of misjudging the moving direction of the passenger

Regarding the above problems and countermeasures thereof, none of the above-mentioned Patent Document 1 and Patent Document 2 is disclosed.
