Description

  The present invention relates to an entrance / exit management system for managing traffic, and for example, relates to an entrance / exit management system for managing entrance / exit of a building.

  2. Description of the Related Art In an automatic ticket gate system such as a railway organization, a wireless card system is disclosed in which an automatic ticket gate device performs bid or bid processing by holding a wireless card over a wireless card reader / writer (see, for example, Patent Document 1). .

  In addition, as an entrance / exit management system for managing entrance / exit of building passers-by, a combination of an ID card and a card reader is generally used. In the ID card, an ID number for identifying an individual is written in advance as personal identification information. On the other hand, the card reader is installed on a wall surface such as a doorway of a building or an indoor doorway in order to read the ID number in the ID card. In order to open the door of the entrance / exit, the passer-by passes the ID card held by the card reader. The ID number information read by the card reader is sent to the traffic management control unit connected to the card reader. The traffic management control unit decodes the transmitted ID number information and performs door opening / closing control based on the decoding result. As a result, it is possible to give permission to enter and leave only passers-by who have an ID number registered in advance in the traffic management control unit.

  In the above description, the card reader is connected to the traffic management control unit with a cable. That is, the card reader communicates with the traffic management control unit via this cable. Here, the card reader is installed in a general section corresponding to a room or a corridor through which a passerby passes. On the other hand, the traffic management control unit is not directly operated by a passer-by, and is often installed in an equipment section corresponding to a machine room or the like.

  However, the prior art has the following problems. As described above, a considerable amount of construction (wiring) costs are required to connect the card readers and traffic management control units installed in different sections with cables. Furthermore, in order to supply electric power to the card reader itself, cable wiring for taking in electric power from the power source or from the traffic management control unit is also required separately, and construction (wiring) costs are required. In particular, when an entrance / exit management system is additionally installed in an existing building, these additional wirings are required. The cost associated with additional wiring is considerably higher than when wiring in advance as in a new building.

  Further, when such additional wiring is performed, it is not practical to pass the wiring through the wall because of the great cost. Therefore, the wiring is usually routed along the wall surface. However, when the cable connecting the card reader and the traffic management control unit or the cable connecting the card reader and the power source is exposed particularly in the general section, it looks very bad. Furthermore, since the cable is exposed, there is a risk of causing cable disconnection or the like.

  The present invention has been made to solve the above-described problems, and an object thereof is to obtain an entrance / exit management system capable of reducing construction costs.

An entrance / exit management system according to the present invention includes an entrance / exit management including a personal information reading unit that reads personal identification information, and a traffic management control unit that performs traffic management based on the personal identification information read by the personal information reading unit. The system further includes a relay unit that is connected to the traffic management control unit and has a sending unit that sends energy to the personal information reading unit, and the personal information reading unit is installed in a different section from the traffic management control unit. And receiving means for receiving energy from the relay unit.

  The entrance / exit management system of the present invention uses the sending means and the receiving means to supply energy from the relay part to the personal information reading part, thereby eliminating the need for wiring of the personal information reading part accompanying the energy supply, and the construction cost. There is an advantage that it is possible to achieve reduction.

DESCRIPTION OF EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. The entrance / exit management system in the following embodiment performs entrance / exit management of building passers-by. FIG. 1 is a configuration diagram of an entrance / exit management system according to an embodiment of the present invention. The building section is divided into a general section 1 through which general users pass (specifically, a room and a corridor) and an equipment section 2 in which facilities such as electricity and water are installed (specifically, a machine room). It is divided roughly into.

  A card reader 3 corresponding to a personal information reading unit is installed in the general section 1 for the purpose of performing entrance / exit management. Further, a relay unit 4 is installed near the ceiling of the card reader 3. Communication between the card reader 3 and the relay unit 4 is wireless, and no communication cable is required. Further, the power necessary for operating the card reader 3 is configured to be supplied from the relay unit 4.

  On the other hand, a traffic management control unit 5 is installed in the facility section 2. Further, the traffic management control unit 5 is connected to the relay unit 4 installed in the general section 1 by a cable 6. With this configuration, the traffic management control unit 5 can communicate with the card reader 3 via the cable 6 and the relay unit 4. The card reader 3 wirelessly communicates the ID number read from the ID card 7 possessed by the passerby to the relay unit 4. Next, the relay unit 4 transmits the ID number received by wireless communication from the card reader 3 to the traffic management control unit 5 via the cable 6. The traffic management control unit 5 decodes the received ID number and outputs a control signal based on the decoding result to perform door opening / closing control.

  Next, details of energy supply and data communication between the card reader 3 and the relay unit 4 will be described below. FIG. 2 is an internal configuration diagram of the card reader 3 and the relay unit 4 according to the embodiment of the present invention. 2A is a top view and FIG. 2B is a side view.

  First, energy supply from the relay unit 4 to the card reader 3 will be described. The relay unit 4 includes a light source 8 that emits light energy toward the card reader 3. On the other hand, the card reader 3 includes a photoelectric converter 9 that receives light energy emitted from the light source 8 and converts it into electrical energy. The card reader 3 uses the power generated by the photoelectric converter 9 as operating power. Here, the light source 8 corresponds to a sending unit, and the photoelectric converter 9 corresponds to a receiving unit. Moreover, as the photoelectric converter 9, a solar cell can be used, for example.

  Thus, by performing energy supply using the light source 8 and the photoelectric converter 9, cable wiring for supplying power to the card reader 3 can be eliminated. This makes it possible to reduce the construction cost, especially when an additional entry / exit management system is installed later. Further, the light source 8 can bring stable power generation to the photoelectric converter 9 even when the illuminance in the building is insufficient, such as at night or overcast. Furthermore, the card reader 4 and its surroundings can be illuminated even when the corridor is completely dark, such as at midnight.

  In the present embodiment, the relay unit 4 is installed near the ceiling almost directly above the card reader 3. Thereby, it becomes possible to eliminate the influence of an obstacle between the relay unit 4 and the card reader 3 and to install the relay unit 4 and the card reader 3 close to each other, and to efficiently generate the photoelectric converter 9. be able to.

  Next, power supply when a power storage unit is further provided will be described. In FIG. 2, the card reader 3 further includes a storage battery 10 corresponding to storage means. The storage battery 10 is charged using a part of the power generated by the photoelectric converter 9. The storage battery 10 serves to supply power supplementarily when the operating power supplied from the photoelectric converter 9 is insufficient. Thereby, it is not necessary to select the capacity of the photoelectric converter 9 according to the maximum power of the card reader 3, and the capacity and size of the photoelectric converter 9 can be reduced. Furthermore, even when the photoelectric converter 9 is blocked by some cause (such as mischief) and cannot generate power, the card reader 3 can be operated by supplying power from the storage battery 10.

  Next, a wireless communication means for performing data communication between the relay unit 4 and the card reader 3 will be described. In FIG. 2, the relay unit 4 and the card reader 3 further include infrared communication means 12 that is a kind of wireless communication means. By installing the relay unit 4 near the ceiling of the card reader 3 and eliminating intermediate obstacles, wireless communication by infrared communication is possible. The card reader 3 can transmit the ID number read from the ID card 7 possessed by the passer-by to the relay unit 4 using the infrared communication means 12.

  Data communication between the card reader 3 and the traffic management control unit 5 can be directly performed by radio using radio waves without using the relay unit 4. On the other hand, when the relay unit 4 is installed and data communication between the card reader 3 and the traffic management control unit 5 is performed using infrared communication between the card reader 3 and the relay unit 4, the following advantages are obtained. . In other words, by using infrared communication, it is possible to avoid interference with radio waves of mobile phones and radio waves of wireless LANs that are rapidly spreading in offices in recent years. In addition, power consumption can be reduced compared to radio using radio waves.

  In addition, in FIG. 2, although the case where infrared communication was utilized for communication with the card reader 3 and the relay part 4 was demonstrated, wireless communication methods other than infrared communication are also applicable. When wireless communication other than infrared communication is used, there are the following merits as in the case of using infrared communication. That is, the data communication cable between the card reader 3 and the relay unit 4 can be made unnecessary, and the card reader 3 becomes an obstacle to wireless communication by performing wireless communication with the relay unit 4 at a short distance. Stable data communication can be performed while suppressing the influence of other radio waves and obstacles.

  Next, another method that can reduce power consumption will be described. In FIG. 2, the relay unit 4 further includes a person sensor 11 corresponding to a person detection unit. The relay unit 4 is installed near the ceiling of the card reader 3, and the person sensor 11 detects whether there is a passerby near the card reader 3 from the upper part of the card reader 3. Furthermore, the detection signal from the person sensor 11 can be transmitted from the relay unit 4 to the card reader 3 by the infrared communication means 12.

  The card reader 3 can identify whether or not a passerby is nearby based on the received detection signal of the person sensor 11. When the detection signal of the person sensor 11 is in the OFF state (that is, the passerby is not in the vicinity), the card reader 3 sets its own operation mode to the standby state. On the other hand, when the detection signal of the person sensor 11 is in the ON state (that is, the passerby is in the vicinity), the card reader 3 returns its operation mode to the normal state and prepares for the reading operation of the ID card 7. .

  As described above, the card reader 3 can suppress power consumption by switching the operation mode based on the detection signal of the person sensor 11 and setting the operation mode to a standby state when there is no passerby. As a result, the capacity and size of the photoelectric converter 9 and the storage battery 10 can be reduced. Further, when the passer wants to use the card reader 3, the card reader 3 can detect in advance the state where the passer is present based on the detection signal of the person sensor 11, and can return the operation mode to the normal state. .

  In order to switch the operation mode of the card reader 3 and reduce power consumption in this way, a method of attaching the person sensor 11 to the card reader 3 itself instead of the relay unit 4 is also conceivable. When the card reader 3 itself includes the person sensor 11, the card reader 3 does not need to receive the detection signal from the relay unit 4, but the operating power for the person sensor 11 is received from the photoelectric converter 9 or the storage battery 10. It is necessary to supply.

  On the other hand, when the relay unit 4 includes the person sensor 11, the relay unit 4 needs to transmit a detection signal to the card reader 3. However, on the other hand, the person sensor 11 can be attached to the vicinity of the ceiling, the detection area can be widened, and a stable detection signal can be obtained from the top without an obstacle. Furthermore, it is not necessary to supply operating power for the person sensor 11 from the photoelectric converter 9 or the storage battery 10. As a result, the card reader 3 does not have to bear the power consumption of the person sensor 11, and the power consumption can be suppressed.
