Embodiment 1.
FIG. 1 is a diagram showing an example of a traffic management system according to Embodiment 1. FIG. The traffic management system includes a door 1 , a reader 2 , a control device 3 and a monitoring device 4 .

In a building equipped with this system, a door 1 is provided at a place where it is necessary to control the passage of people. A large number of doors 1 are provided in the building. Each door 1 is provided with an electric lock 5 .

The reading device 2 reads identification information from the storage medium 6 . If the reading device 2 is a card reader, the storage medium 6 is a card such as an employee ID card. For example, a user of the system holds his or her employee ID card over a card reader. Thereby, the card reader reads the identification information from the tag embedded in the employee ID card.

FIG. 1 shows an example in which one reader 2 is provided for one door 1 . In the example shown in FIG. 1, the reader 2 is provided adjacent to the corresponding door 1 . If the door 1 is a door for entering and exiting a room, the reader 2 may be provided both inside and outside the room.

A control device 3 controls the door 1 and the reader 2 . For example, a power line is connected between the control device 3 and the reading device 2 . The control device 3 supplies the reading device 2 with a voltage necessary for its operation. A signal line is connected between the control device 3 and the reading device 2 . After reading the identification information from the storage medium 6 , the reading device 2 transmits the read identification information to the control device 3 .

The traffic management system may comprise a plurality of controllers 3. In the example shown in FIG. 1, one of the controllers 3 controls three sets of doors 1 and readers 2 . The control device 3 will be described in detail below. Further, when the door 1 and the reader 2 controlled by the control device 3 need to be individually specified, letters A to C are added after the reference numerals as shown in FIG. For example, reader 2A is a reader corresponding to door 1A. The door 1A has an electric lock 5A. Similarly, reader 2B is the reader corresponding to door 1B. A reader 2C is a reader corresponding to the door 1C.

FIG. 2 is a diagram for explaining the functions of the control device 3. As shown in FIG. The control device 3 includes a storage unit 10 , a communication unit 11 and a collation unit 12 .

Information of a person who is permitted to pass through the door 1 is stored in the storage unit 10 for each door 1. - 特許庁The information is the same information as the information read by the reading device 2 from the storage medium 6 . For example, the storage unit 10 stores a list of authorized passers for the door 1A. Identification information assigned to persons permitted to pass through the door 1A is registered in advance in the list.

Similarly, the storage unit 10 stores a list of authorized passers for the door 1B. Identification information assigned to a person who is permitted to pass through the door 1B is registered in advance in the list. The storage unit 10 stores a list of authorized passers for the door 1C. Identification information assigned to persons permitted to pass through the door 1C is registered in advance in the list.

FIG. 3 is a flow chart showing an operation example of the control device 3 . In the control device 3, it is determined whether or not identification information has been received from the reading device 2 (S101). As described above, when reading the identification information from the storage medium 6 , the reading device 2 transmits the read identification information to the control device 3 . When the control device 3 receives the identification information from the reading device 2, it is determined as Yes in S101.

If it is determined as Yes in S101, the collation unit 12 collates the identification information read by the reading device 2 with the registered information stored in the storage unit 10 (S102).

As an example, consider a case where the control device 3 receives the identification information from the reading device 2A in S101. In such a case, the collation unit 12 determines whether or not the identification information read by the reading device 2A matches the corresponding registered information (S103). In this example, the corresponding pre-registered information is the identification information pre-registered in the permitted passer list for the door 1A.

If the identification information read by the reading device 2A matches the corresponding registered information, the collation unit 12 determines Yes in S103. If determined as Yes in S103, the communication unit 11 transmits unlocking information to the electric lock 5A of the door 1A (S104). The door 1A is thereby unlocked. Further, in the control device 3, the identification information read by the reading device 2A and the information indicating that the unlocking information has been transmitted to the electric lock 5A are recorded as a log (S105).

On the other hand, if the identification information read by the reading device 2A does not match the corresponding registered information, the collation unit 12 determines No in S103. If determined as No in S103, the communication unit 11 does not transmit unlocking information to the electric lock 5A. For this reason, the door 1A is not unlocked if it is determined as No in S103.

If it is determined as No in S103, the communication unit 11 transmits mismatch information to the monitoring device 4 (S106). The discrepancy information is information indicating that the identification information read by the reading device 2A does not match the corresponding registered information. Further, in the control device 3, the identification information read by the reading device 2A and the information indicating that the information indicating that the identification information read by the reading device 2A does not match with the information is recorded as a log (S105).

FIG. 4 is a flow chart showing an operation example of the monitoring device 4 . The monitoring device 4 includes a display device 20, a communication section 21, and a display control section 22 as shown in FIG. In the monitoring device 4, it is determined whether or not mismatch information has been received from the control device 3 (S201). When the communication unit 21 receives the mismatch information transmitted from the control device 3 in S106, it is determined as Yes in S201.

If determined as Yes in S201, the display control unit 22 displays a warning on the display 20 (S202). The warning includes information indicating that a person who is not permitted to pass through the door 1A tried to pass through the door 1A. As an example, the monitoring device 4 is a computer provided in a building control room. A person in the control room can know that an inappropriate operation has been performed on the reading device 2A by looking at the warning displayed on the display 20 .

FIG. 5 is a flow chart showing another operation example of the control device 3 . The control device 3 further includes detectors 13 to 15, as shown in FIG. The detection units 13 to 15 constitute means for detecting failures occurring in this system.

The detection unit 13 determines whether or not a voltage abnormality has occurred in the reading device 2 (S301). As mentioned above, the voltage for reader 2 is supplied by controller 3 . As an example, when the voltage supplied to the reading device 2 falls below the threshold, the detection unit 13 detects a voltage abnormality with respect to the reading device 2 (Yes in S301). The detection unit 13 performs the determination of S<b>301 for each reading device 2 .

If determined as Yes in S301, the communication unit 11 transmits the first abnormality information to the monitoring device 4 (S302). The first abnormality information includes information indicating that a voltage abnormality has occurred and information about the reader 2 in which the voltage abnormality has occurred. Further, in the control device 3, information corresponding to the first abnormality information is recorded as a log (S307).

When determined as No in S301, the detection unit 14 determines whether or not the signal line connected between the reading device 2 and the control device 3 is broken (S303). Any method may be used for the detection unit 14 to detect disconnection. The detection unit 14 performs the determination of S<b>303 with respect to the signal line connected to each reading device 2 .

When the detection unit 14 detects disconnection of the signal line connected to the reading device 2 (Yes in S303), the communication unit 11 transmits second abnormality information to the monitoring device 4 (S304). The second abnormality information includes information indicating that a disconnection has occurred and information about the reader 2 to which the signal line in which the disconnection has occurred is connected. Further, in the control device 3, information corresponding to the second abnormality information is recorded as a log (S307).

If the determination in S303 is No, then an appropriate voltage is being supplied to the reading device 2 and the signal line is not disconnected. When it is determined No in S303, the detection unit 15 determines whether or not the reading device 2 has a response abnormality (S305). As an example, the detection unit 15 transmits an interrogation signal from the communication unit 11 to the reading device 2 . If the detection unit 15 cannot receive a response signal to the question signal from the reading device 2, it detects a response abnormality of the reading device 2 (Yes in S305). The detection unit 15 performs the determination of S<b>305 for each reading device 2 .

If determined as Yes in S305, the communication unit 11 transmits the third abnormality information to the monitoring device 4 (S306). The third abnormality information includes information indicating that a response abnormality has occurred and information about the reader 2 in which the response abnormality has occurred. Further, in the control device 3, information corresponding to the third abnormality information is recorded as a log (S307).

FIG. 6 is a flow chart showing another operation example of the monitoring device 4 . In the monitoring device 4, it is determined whether or not the first abnormality information has been received from the control device 3 (S401). When the communication part 21 receives the 1st abnormality information transmitted from the control apparatus 3 by S302, it will be determined as Yes by S401. When determined as Yes in S401, the display control unit 22 displays the information indicating that the voltage abnormality has occurred and the information of the reading device 2 in which the voltage abnormality has occurred on the display 20 based on the received first abnormality information. (S402). That is, when the detection unit 13 of the control device 3 detects a voltage abnormality, the display device 20 of the monitoring device 4 displays that effect.

If it is determined No in S401, the monitoring device 4 determines whether or not the second abnormality information has been received from the control device 3 (S403). When the communication unit 21 receives the second abnormality information transmitted from the control device 3 in S304, a determination of Yes is made in S403. If determined as Yes in S403, the display control unit 22, based on the received second abnormality information, displays information indicating that the disconnection has occurred and information about the reading device 2 to which the signal line in which the disconnection has occurred is connected. is displayed on the display 20 (S404). That is, when the detection unit 14 of the control device 3 detects a disconnection, the display 20 of the monitoring device 4 displays that fact.

If it is determined No in S403, the monitoring device 4 determines whether or not the third abnormality information has been received from the control device 3 (S405). When the communication unit 21 receives the third abnormality information transmitted from the control device 3 in S306, it is determined as Yes in S405. When determined as Yes in S405, the display control unit 22 displays the information indicating that the response abnormality has occurred and the information of the reading device 2 in which the response abnormality has occurred on the display device 20 based on the received third abnormality information. (S406). That is, when the detection unit 15 of the control device 3 detects a response abnormality, the display device 20 of the monitoring device 4 displays that effect.

When a failure occurs in this system, maintenance personnel are dispatched from the maintenance company. When the maintenance worker arrives at the site, the maintenance worker checks the display 20 of the monitoring device 4 installed in the control room. In this system, if the detection unit 13 detects a voltage abnormality, the display 20 displays that effect. Similarly, if the detection unit 14 detects disconnection, the display 20 displays to that effect. If the detection unit 15 has detected a response abnormality, the display 20 displays to that effect. Therefore, by checking the display 20, maintenance personnel can isolate the cause of the failure. Maintenance personnel do not need to perform useless work to identify the cause of the failure, and the time required for restoration work can be shortened.

It should be noted that the voltage abnormality detected by the detection unit 13 may occur temporarily. Therefore, when the detection unit 13 no longer detects the voltage abnormality after the first abnormality information is transmitted in S302, the display control unit 22 may erase the content displayed on the display 20 in S402. Similarly, a response abnormality detected by the detection unit 15 may occur temporarily. Therefore, when the detection unit 15 no longer detects a response abnormality after the third abnormality information is transmitted in S306, the display control unit 22 may erase the content displayed on the display 20 in S406.
