Abstract

PURPOSE:To constitute a gate without distinguishing entrance and exit passages by suppressing the change of status logic in a commutation ticket during the passing period of the gate and inverting the internal state of the commutation ticket at proper time after passing the gate. CONSTITUTION:The electronic commutation ticket is provided with a storage part FF for storing whether the user is going into or out the gate, detection parts 12 to 15 for detecting entrance/exit information generated from stations, output parts LO, LI for outputting after distinguishing between entrance and exit and logical circuits parts NA, NOT, MS, NOR for receiving the storage contents of the storage part FF and the outputs of the detection parts 12 to 15, outputting prescribed signals to the output parts LO, LI only for a prescribed time and inverting the contents of the storage part FF almost simultaneously with the end of the outputs. After the lapse of the prescribed time from the reception of the entrance/exit information generated from the station, the contents of the storage part FF are rewritten. Consequently, distinction between entrance and exit passages can be removed and a radio transmission part can be omitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to electronic commuter passes used in transportation facilities and computerized.

[Conventional technology]

Recently, research has been underway to use individual identification devices W (read or read and write memory devices W capable of contactless communication) in place of commuter passes. In this case, the commuter pass will contain information such as the available sections, available period of use, available routes, user name and individual identification (ID) number to identify the user in a memory that enables contactless communication. Necessary information will be set. Therefore, in this memory, for example, at the ticket gate you pass through when entering a station,
If you set a ride record when you board a public transportation such as a bus or train, you can keep a record of your ride.

Also, as a similar method, there are commuter passes that use magnetic cards, mainly on private railways. In this case, the valid section, period, usage classification, etc. are stored in the memory of the magnetic card in the same way as above, and the memory is read every time you enter or exit the transportation period, and the information is read out every time you enter or exit the transportation period. In addition to method 4, which determines whether or not the card can be used, there is a method that uses a prepaid card.

This card uses a card (often a magnetic card) that is purchased by paying a certain amount in advance, such as 1,000 yen, 3,000 yen, or 5,000 yen. As an example of such a system, an experimental system used in place of a coupon ticket on route buses has been reported in newspapers, and has been put into practical use in some cases. In this case, a method is used in which the boarding location is memorized when boarding the vehicle, and the fare for the boarding section is deducted from the available amount on the card when getting off the vehicle.

[Invention or problem to be solved]

With the memory device capable of contactless communication as described above, there is a problem in that in order to ensure the reliability of wireless communication, it is necessary to separate the paths for those entering the bath and those entering the bath, as shown in Figure 5. be.

In addition, in order to prevent unauthorized boarding and ticket purchases, it is necessary to read the commuter pass information as shown in Figure 6, but when using wireless communication means, a wireless transmitter is required inside the commuter pass, and the commuter pass information is read as shown in Figure 6. There is also the problem that it is expensive.

Therefore, the purpose of this invention is to
To provide an electronic commuter pass that can eliminate the number 1 and does not require a wireless transmitter.

[Means for solving the problem] - A memory unit that remembers whether the user is entering or participating, and a person issuing from the station;
a detection unit that detects hot spring exit information; an output unit that outputs information on entry and exit; and an output unit that receives the memory contents of the storage unit and the output of the detection unit, and outputs the output information depending on whether it is entry or exit. A logic circuit section is provided that outputs a predetermined signal to the output section for a predetermined period of time and inverts the contents of the storage section substantially simultaneously with the end of the output.

[Effect]

By receiving information about people and hot springs issued from the station and rewriting the contents of the storage part after a predetermined time based on the information, there is no distinction between entry and hot water exit in the passage, and a wireless transmitting part is not required.

〔Example〕

Fig. 1 is an overall configuration diagram showing an embodiment of this invention, Figs. 2C and 2C are time charts for explaining its operation, and Fig. 3 is a schematic diagram showing the arrangement of ticket gates in this invention. 4 are perspective views showing the appearance of the electronic commuter pass according to the present invention.

That is, in this embodiment, as shown in Fig. 3, the passageway of the ticket gate is structured without distinguishing between entry and exit, and basically the entrance 5 is clearly marked and oscillators etc. are arranged accordingly. (preferably), each passageway is equipped with a wireless communicator F that transmits an entry code.

and a wireless transmitter F2 that transmits a hot water tap code. Therefore, commuter passes passing through the aisles are exposed to these radio transmitters F. , and will definitely receive both radio waves from F2.

As shown in Fig. 4, the electronic commuter pass has a display section I on the commuter pass as an output section indicating entry and an output section indicating hot spring access.
A, IB are prepared (assumed). Note that it is also possible to generate a sound instead of displaying the display. Fig. 1 will be explained below. Here, the entrance code is represented by the frequency f1. , the hot water tap code is expressed by the frequency f2.Also, a method of using the code as a digital signal and controlling the wireless carrier frequency is also considered,
The principle is the same.

That is, the frequency 1m from the oscillator 31 is modulated by the modulator 32 using the carrier frequency fc, amplified through the amplifier 33, and the radio wave f:10fc is transmitted from the antenna 34. Similarly, the frequency 12 from the transmitter 21 is modulated by the carrier frequency fc in the modulator 22, amplified through the amplifier 23, and radio waves f, +fc are transmitted from the antenna 24.

When the commuter pass 1 passes through the ticket gate, the antenna 1 receives the radio waves, amplifies them with the amplifier 12A, and then sends them to the mixer 1.
3 and the carrier wave frequency fc from the carrier wave oscillator 14, and further amplified by the amplifier 12B, the frequencies f, , f are mixed by the band pass filters (BPF) 15A and 15B, respectively.

Take out.

The operation inside the commuter pass I will be explained with reference to FIGS. 2C to 20.

In commuter pass l, both frequencies f, , f are detected, and NA2. It is input to NAI, but NAl is the output of the Friab flop FF that stores the status of the commuter pass.
, that is, "active 0 when entering 1". On the other hand, NA2 is a flip-flop FF
Since the output of ``NOT'' is inverted by NOT, when the output of FF 1FF, which stores the status of the commuter pass, is 0, that is, it becomes active 0 when the bath is in January. indicates the state in which the participant is inside the station premises, and "entering" refers to the state in which the participant exits the station premises, and shall be included in the entering state when paying the bill.

FIG. 2C shows a flowchart for formal entry; at this time, the output of the Friab flop FF is 0, that is, the player is entering, and therefore the output of the Nantes gate NA2 is active "0". When the - output of Nant gate NA2 becomes active, one-shot circuit MS2
is turned on for a certain period of time (indicated as T in FIG. 2C), and this is applied to the input display element Ll via the driver DR2, causing it to light up. At the same time, the output of the one-shot circuit MS2 activates the NOR circuit NOR for a certain period of time, and after the period ends, the rising signal (■
) to invert the state of the FRIAB flop FF. As a result, the status of the commuter pass changes from "participating" to "entering".

Figure 2B shows a flowchart for officially dispensing hot water. In this case, since the state of the FF is 1", NA1 becomes active 0", and the output of the one-shot circuit MSI is maintained for a certain period of time ( In Figure 2B, T
2) is turned on and the driver DP
The output display element LO is turned on via I. Further, at the point (■) in the figure after a certain period of time has ended, the status of the FRIAB FLOW and FF is reversed, and the status of the commuter pass is rewritten to ``currently participating'' (0).

FIG. 2C is an example of unauthorized use of a commuter pass to access the hot springs without entering the facility (entering with a ticket ticket). In this case, the state of the flip-flop FF is 0, which means that it is "entering", and when entering, the frequency r1 is detected, the Nant gate NA2 becomes active 0", and the one-shot circuit MS2 is activated for a certain period of time T.

Since the input display element Ll is turned on, the input display element Ll lights up. In other words, an entrance display is displayed even though the user is about to enter the bath, and since there is a contradiction in the display, it is possible to determine that it is fraudulent.

The output method is, for example, yellow LED for entrance display.
(Light emitting element), a red LED is used to indicate hot water access, and when unauthorized entry/exit, both LEDs are turned on or flashed at the same time, making it easy to visually check the usage status of the commuter pass. In addition, although the state of the Furiabu Fluosop FF is reversed almost at the same time as the display ends, by providing another one-shot circuit on the output side of the NOR gate, the display confirmation and memory data rewriting time can be optimized. It becomes possible to aim for.

The above focuses mainly on preventing unauthorized use, and therefore does not explain decisions such as whether the commuter pass is used within the valid section or within the valid period. However, it goes without saying that these functions can be provided as appropriate depending on the purpose of use.

(Effects of the Invention) According to the present invention, the state logic inside the commuter pass is not changed while passing through the ticket gate, and the state inside the commuter pass is reversed at an appropriate time after passing through the ticket gate. As a result, a ticket gate can be configured without separating the entry and exit passages.Also, the usage status of the commuter pass can be changed without reading out the data inside it, so it is possible to reduce the cost without installing a wireless transmitter. This has the advantage of being able to prevent unauthorized use and incorrect Icheon.
