Abstract

PURPOSE:To certainly read the identification card carried by a passenger and to enhance passage efficiency by mutually compensating the reading insensitive band region of the identification card generated by the passage position of the passenger in a passage control room. CONSTITUTION:The transmission levels of the question radiowaves of card readers 3, 11 are controlled to form a card reading region MNPQ. That is, the transmission levels of the question radio waves of the card readers 3, 11 are controlled to compensate the mutual reading insensitive band regions. It is assumed that a passenger passes, for example, in an A-direction in the passage control room 2 formed within a card reading range. When the passenger turns an entry switch 12 ON, a control door 4 is locked by the order signal from a CPU 14. The passenger entering the passage control room passes through the card reading region of either one of card readers 3, 11 to read the carried identification card.

Description

[Detailed Description of the Invention] [Object of the Invention] [Field of Industrial Application] The present invention relates to a traffic control device used for controlling passersby entering and exiting important facilities, for example, and particularly relates to a traffic control device carried by passersby. The present invention relates to a traffic management device that manages passersby by reading the contents of wireless identification cards.

[Conventional technology]

FIG. 2 is a perspective view showing a schematic configuration of a conventional traffic management device. The traffic management device 1 shown in the figure includes a traffic management room 2 through which passersby carrying wireless identification cards pass, and a wireless identification card installed on one side wall of the traffic management room 2 to allow passersby to carry their wireless identification cards. The main components are a card reader 3 that constantly transmits question radio waves to the traffic control room 2, and a control door 4.5 that controls entry and exit from the traffic management room 2. Note that the space (passage) of the traffic control room 2 is formed by side walls 2a and 2b, and is set to a size large enough for -1 passerby to pass through.

Further, the opening and closing of the control doors 4 and 5 is controlled so as to allow entry into the traffic management room 2 from both directions.

The traffic management device 1 configured as described above operates as follows. A passerby enters the traffic control room 2 and uses the card reader 3.
At this time, since the card reader 3 is transmitting the interrogation radio wave, the wireless nichubetsu card carried by the passerby receives the interrogation radio wave.

At this time, a response radio wave is sent from the identification card to the card reader 3. In this way, the identification card can be read by the card reader 3.

FIG. 3 is a diagram showing the readable range of the card reading device 3. That is, the range in which a card can be read varies greatly depending on the orientation and angle of the card relative to the interrogation radio wave. The solid line area M shown in the figure indicates the readable range when the card is directly facing the card reader 3, and
A broken line N indicates a readable range when the card is perpendicular to the card reader 3. Card reading area M
.

The portion other than N, that is, R becomes a reading dead zone area where the card cannot be read.

Therefore, if a passerby passes through the traffic control room 2 having the card reading areas M and N and the reading dead zone R as described above in the direction of arrow A in the figure while carrying an identification card in his left pocket, for example. At this time, if the identification card passes through the card reading area (M or N), the identification card is read by the card reader 3. However, if a passerby carrying an identification card in his left pocket passes through the traffic control room 2 in the direction of arrow B, there is a very high possibility that the identification card will not pass through the card reading area (M, N). There is a possibility that the vehicle passes through the traffic control room 2 without being read. Therefore, when a passerby passes through the identification card reading dead zone R, for example, he takes out the identification card from his pocket and brings it close to the card reader 3 to have the card read. This obstructed smooth passage.

In addition, in order to reduce the dead zone area as much as possible, the transmission level of the interrogation radio wave is increased, and the card reading area (M) is increased.

N) is widened to cover the area between the side walls 2a and 2b of the traffic control room 2, but as a result, when the transmission level of the interrogation radio waves is increased, the area between the side walls 2a and 2b of the traffic control room It even extends outside the control room 2. Therefore, there is a high possibility that even the cards of passersby waiting outside the traffic management room 2 will be read, resulting in the inconvenience that passersby cannot be accurately managed. In addition, since the size of the traffic control room 2 is set to be large enough for one person to pass through, we have installed a shielding plate to prevent interrogation radio waves from leaking outside the traffic control room 2. It is not possible to take measures such as providing a shield in the card reading dead zone R in the room 2 to prevent passage.

[Problem to be solved by the invention]

Therefore, as described above, the conventional traffic management device 1 may not be able to read the identification card carried by a passerby, or may read the identification card of a passerby other than the one it is supposed to read, and may not be able to accurately pass traffic. The system was unreliable as it was not possible to manage the personnel.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a traffic management device that can accurately manage passersby and allows passersby to pass smoothly, thereby improving traffic efficiency.

[Structure of the Invention] [Means for Solving the Problems] In order to solve the above problems and achieve the objects, the present invention takes the following measures. In other words, in a traffic management device that performs traffic management by reading the contents of wireless identification cards carried by passersby, the ID card reading dead zone area that occurs depending on the passerby's passage position within the traffic control room is complemented, and the card reading A plurality of card readers are installed so that the area does not extend beyond the traffic control room.

[Effect]

Therefore, by taking the above measures, the present invention suppresses the transmission level of a plurality of card readers, thereby preventing the card reading range from going outside the traffic control room, and supplementing the 4j7 areas in which identification cards are not read. , ID cards can be read reliably and accurately no matter what conditions the vehicle is passing through.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the configuration of a traffic management device that is an embodiment of the present invention. Note that the same parts as those of the traffic management device 1 shown in FIG. 3 are given the same reference numerals, and detailed explanation thereof will be omitted. That is, this device can be installed on each side wall 2a, 2 of the traffic control room 2.
Card readers 3 and 1] are installed at each of the terminals b.

12 and 13 are entry switches, and a passerby enters the traffic management room 2 after pressing the entry switch 12 or 13. 14 is composed of, for example, a CPU, and switch 1
This is a control means that unlocks the control door 4.5 upon receiving the ON signal of 2 or 13.

Note that this control means 14 can also be performed using a relay instead of the CPU.

Next, the operation of the traffic management device configured as above will be explained. The transmission level of the interrogation radio waves transmitted from the card readers 3 and 11 is adjusted to form card reading areas M, N, P, and Q as shown in the figure. That is, the transmission levels of the interrogation radio waves of the card readers 3 and 11 are adjusted to complement each other's reading dead zone areas. Note that P and Q are the card reading ranges formed by the card reader 11, P is the card reading range when the identification card faces the card reader 11, and Q is the card reading range when the identification card is directly facing the card reader 11. This is the card reading range when positioned perpendicular to the card. The traffic control room 2 formed in such a card reading range,
For example, suppose that a passerby passes in the direction of the arrow. A passerby who has come to the traffic management device presses the entry switch 12. When the entry switch 12 is turned on, the control door 5 is unlocked by a command signal from the CPU 14, and the control door 4 on the opposite side is locked. Passersby entering the traffic control room 2 pass through the card reading area of either the card reader 3 or 11, and the identification card they are carrying is read. The data of the read Kyoubetsu card is sent to the CPU14.
Or stored in the storage section of an external device. Further, when the identification card is read, a command signal is sent from the CPU 14 to the control door 4, the control door 4 is unlocked, and the passerby exits the traffic control room 2. Further, when the user presses the entry switch 13 and passes in the direction of arrow B, the same process as described above is performed. As passersby pass through the traffic management room 2 in this manner, data such as who entered and exited at what time and from which gate is obtained, and passersby are managed based on this data.

In this way, according to this embodiment, both side walls 2 of the traffic control room 2
Since the card readers 3 and 11 are installed on the side walls 2a and 2b, and the reading dead zone areas are complemented with each other,
The card reading area can be extended to the entire area between b and the identification card carried by a passerby can be reliably read. Furthermore, since the identification card can be read even if it is carried in a pocket or the like, passersby can pass through the traffic management room 2 smoothly. In addition, since the card reading area can be applied to the entire area between the both side walls 2a and 2b at a low output power transmission level, the card reading area does not leak outside the traffic control room 2, and the reader can wait outside the traffic control room 2. There is no chance of accidentally reading someone's identification card. Furthermore, a large number of similar traffic management devices can be arranged in close proximity, making traffic management more efficient.

In the above embodiment, both side walls 2a, 2 of the traffic control room 2
A card reader 3 is installed at the entrance of the facility, but it is also possible to install multiple card readers 3.11 near the entrance of the facility (for example, the entrance door) to manage passersby. good.

[Effects of the Invention] As detailed above, according to the present invention, identification cards carried by passersby can be reliably read, there is no misreading, the reliability is extremely high, and the efficiency of passing can be improved. We can provide traffic management equipment.
