  Further, the security system 1 includes a center device 50 composed of a computer or the like. The security devices 40A, 40B, 40C and the center device 50 are connected to be communicable with each other via a network NW.

≪Security device≫
The security device 40 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read-Only Memory), an input / output circuit, and the like. As shown in FIG. Acquisition unit (authentication information acquisition unit) 41, storage unit 42, authentication unit 43, door control unit (gate control unit) 44, card reader control unit (authentication information reader control unit) 45, and table management unit 46 and a clock unit 47.

  The ID information acquisition unit 41 acquires the ID information transmitted from the corresponding card reader and outputs it to the authentication unit 43. Further, the ID information acquisition unit 41 can acquire passable ID information (passable authentication information) transmitted from any one of the other security devices 40 and the center device 50 and output it to the table management unit 46. .

  The storage unit 42 stores an authentication table 42a shown in FIG. 3A as a table for storing passable ID information. Here, the passable ID information is information that associates ID information with whether or not a person carrying the RFID card C having the ID information can pass through the doors 21 to 25.

  Further, the storage unit 42 stores a low level authentication time zone table 42b shown in FIG. 3B as a table for storing the low level authentication time zone information. Here, the low-level authentication time zone information is information in which the low-level authentication start time and end time are associated with each day of the week.

  Further, the storage unit 42 stores a door control table 42c shown in FIG. 3C as a table for storing information in which the authentication location and the security release target door candidate for each security level are associated with each other. The

Returning to FIG. 2, the authentication unit 43 uses the ID information acquired by the ID information acquisition unit 41 to determine whether the door security can be released. More specifically, the authentication unit 43 searches the authentication table 42a for passable ID information corresponding to the ID information. When the passable ID information corresponding to the ID information is found in the authentication table 42a, the authentication unit 43 refers to the low-level authentication time zone table 42b, and the time (currently) counted by the clock unit 47 described later It is determined whether or not (date and time) is a low level authentication time zone. When the current date and time is in the low level authentication time zone, the authentication unit 43 refers to the door control table 42c and recognizes the security release target door candidate in the low level authentication time zone. Further, when the current date and time is not in the low level authentication time zone (when it is in the normal level authentication time zone), the authentication unit 43 refers to the door control table 42c and selects the security release target door candidate in the normal level authentication time zone. recognize.
Subsequently, the authentication unit 43 specifies a security release target door that is actually controlled to be in a passable state from among the security release target door candidates based on the passable ID information in the authentication table 42a. According to the determination result, the door control unit 44 and the card reader control unit 45 are controlled.

  The door control unit 44 controls the corresponding door based on the determination result by the authentication unit 43. More specifically, the door control unit 44 transmits a security release signal to the corresponding door when the determination result by the authentication unit 43 is such that the door controlled by the door control unit 44 can be opened. Further, the door control unit 44 transmits a security release instruction to the other security device 40 when the result of determination by the authentication unit 43 includes a security release target door other than the door controlled by the door control unit 44.

  The card reader control unit 45 corresponds to the corresponding card reader based on either the determination result by the authentication unit 43, the security release signal from the door control unit 44, or the security release instruction from the door control unit 44 of another security device 40. To control. More specifically, when the result of determination by the authentication unit 43 is that the door can be opened, the card reader control unit 45 transmits a signal indicating that to the corresponding card reader. The card reader that has received such a signal drives a light emitting unit (not shown) to notify the human of the door security state.

  The table management unit 46 manages the authentication table 42a, the low level authentication time zone table 42b, and the door control table 42c. More specifically, the table management unit 46 deletes or updates data in the authentication table 42a, the low-level authentication time zone table 42b, and the door control table 42c in accordance with, for example, an instruction from the center device 50.

  The clock unit 47 counts year / month / day / hour / minute / second.

  According to the security system 1, for example, a person carrying the RFID card C having the ID information “012345789” in FIG. 3 enters the facility 10 and enters the first door 21, the second door 22, and the third door. The door 23, the fourth door 24, and the fifth door 25 can pass through. However, a person carrying the RFID card C having the ID information “98776543211” in FIG. 3 cannot enter the facility 10 and pass through the first door 21, the second door 22, and the third door 23. Although it is possible, the fourth door 24 and the fifth door 25 cannot pass through. In this way, the movement range can be restricted within the facility 10 according to the person, and the security of the facility 10 can be suitably set. And if it is a low level authentication time slot | zone, by performing authentication only once in the 1st door 21, the doors other than the 1st door 21 can also cancel security simultaneously, It can be reduced to improve convenience.

≪Operation example≫
Subsequently, an operation example of the security system 1 according to the embodiment of the present invention will be described with reference to FIGS. In this operation example, the RFID card C having the ID information “98765443211” is read by the first card reader 31. FIG. 4 is a diagram for explaining an operation example of the first card reader and the first security device according to the embodiment of the present invention. FIG. 5 is a diagram for explaining a detailed flow of step S4 of FIG. FIG. 6A is a diagram for explaining an operation example of the second security device according to the embodiment of the present invention, and FIG. 6B is a third security device according to the embodiment of the present invention. It is a figure for demonstrating the operation example of.

  As shown in FIG. 4, first, when a person carrying an RFID card C holds the RFID card C over the first card reader 31, the first card reader 31 displays the ID information that the RFID card C has. Acquire (Yes in step S1), and transmit the acquired ID information to the corresponding first security device 40A (step S2).

  Subsequently, when the ID information acquisition unit 41 of the first security device 40A acquires ID information (Yes in Step S3), the authentication unit 43 performs an authentication process (Step S4).

  In the authentication process (step S4), as shown in FIG. 5, the authentication unit 43 searches the authentication table 42a using the ID information (step S21). If passable ID information corresponding to the acquired ID information is found in the authentication table 42a (Yes in step S21), the flow proceeds to step S22. If the passable ID information corresponding to the acquired ID information is not found in the authentication table 42a (No in step S21), the flow returns to step S3 in FIG.

If Yes in step S21, the authentication unit 43 acquires the current date and time from the clock unit 47 (step S22).
Subsequently, the authentication unit 43 refers to the low level authentication time zone table 42b and determines whether or not the current date and time is in the low level authentication time zone (step S23).
Subsequently, the authentication unit 43 refers to the door control table 42c, and determines which door is the security release target door candidate according to the authentication location and the authentication level (step S24).
Here, when it is determined in step S23 that the current date and time is in the low level authentication time zone, in step S24, the authentication unit 43 determines that the first door 21, the second door 22, and the third door. 23, the 4th door 24 and the 5th door 25 are determined as a security cancellation | release object door candidate. If it is determined in step S23 that the current date and time is not in the low level authentication time zone (that is, the normal level authentication time zone), in step S24, the authentication unit 43 includes only the first door 21. Is determined as a security release target door candidate.

  Subsequently, the authentication unit 43 performs determination for identifying the security release target door from among the security release target door candidates based on the passable ID information (step S25). In this determination, the authentication unit 43 determines whether the passable ID information corresponding to the acquired ID information is “◯” or “X” in the security release target door candidate in the authentication table 42a of FIG. Find out if there is. For example, when the first door 21 is a security release target door candidate as a result of referring to FIG. 3C, the passable ID information corresponding to the acquired ID information in the authentication table 42a of FIG. However, when it is the first door “◯”, the authentication unit 43 determines that the first door 21 is a security release target door. In this operation example, since the ID information is “98765443211”, if it is determined in step S23 that the current date and time is in the low level authentication time zone, in step S25, the authentication unit 43 sets the security release target door. Among the first door 21 to the fifth door 25 that are candidates, the first door 21 to the third door 23 are determined to be security release target doors, and the fourth door 24 and the fifth door 25 are determined. Is not a security release target door. If it is determined in step S23 that the current date and time is in the normal level authentication time zone, in step S25, the authentication unit 43 selects the first of the first doors 21 that are security release target door candidates. It is determined that the door 21 is a security release target door.

Returning to FIG. 4, when the door controlled by the first security device 40 </ b> A includes a security release target door (that is, when the door should be able to pass through, Yes in step S <b> 5), the door control unit 44 performs security. A release signal is transmitted to the corresponding door (step S6). The corresponding door opens automatically based on the security release signal.
Here, when it is determined in step S23 that the current date and time is in the low level authentication time zone, the door control unit 44 transmits a security release signal to the first door 21 and the second door 22. The first door 21 and the second door 22 are automatically opened based on the security release signal. If it is determined in step S23 that the current date and time is not in the low level authentication time zone (that is, the normal level authentication time zone), the door control unit 44 releases the security only to the first door 21. Send a signal. The first door 21 is automatically opened based on the security release signal.

In the case of No in step S5 or after execution of step S6, there is a security release target door in the door controlled by the second security device 40B, which is another security device 40 other than the first security device 40A (step S7). Yes), the door control unit 44 of the first security device 40A transmits a security release instruction to the second security device 40B (step S8). Note that which security device 40 controls which door may be determined based on a table (not shown) in which the correspondence between the security device and the door is registered.
Here, when it is determined in step S23 that the current date and time is in the low level authentication time zone, the door control unit 44 of the first security device 40A controls the security of the third door 23 in step S8. A security cancellation instruction for canceling is transmitted to the second security device 40B. If it is determined in step S23 that the current date and time is not in the low level authentication time zone (that is, the normal level authentication time zone), the door control unit 44 issues a security release instruction to the second security device. There is no transmission to 40B.

If No in step S7 or after execution of step S8, if there is a security release target door on the door controlled by the third security device 40C (Yes in step S9), the door control of the first security device 40A is performed. The unit 44 transmits a security release instruction to the third security device 40C (step S10).
However, in the case of this operation example, the fourth door 24 and the fifth door 25 are not security release target doors. Therefore, in step S23, the current date and time is determined to be in the low level authentication time zone. However, even if it is determined that the current date and time is not in the low level authentication time zone (that is, the normal level authentication time zone), the door control unit 44 issues a security release instruction to the third security device 40C. Never sent to.

Subsequently, as illustrated in FIG. 6A, when the second security device 40B acquires the security release instruction transmitted from the first security device 40A (Yes in step S11), the second security device 40B The door control unit 44 transmits a security release signal to the corresponding door (in this case, the third door 23) (step S12).
Then, the third door 23 is automatically opened based on the security release signal.

  Further, as shown in FIG. 6B, when the third security device 40C acquires the security release instruction transmitted from the first security device 40A (Yes in step S13), the door control unit 44 releases the security. A signal is transmitted to the corresponding door (step S14).

  The door that automatically opens based on the security release signal is automatically closed after a person passes based on the detection result of a human sensor (not shown), and security is set to prohibit the passage of the person. There may be. Further, the door that is automatically opened based on the security release signal may be configured to automatically close after a lapse of a certain time, and security is set so that human traffic is prohibited.

The security device 40 according to the embodiment of the present invention determines whether or not security can be released for a plurality of doors based on ID information read by a single card reader, and controls the doors that are determined to be passable. Since security is released, the number of human movements associated with authentication can be reduced and convenience can be improved.
In addition, the security device 40 according to the embodiment of the present invention also releases the security for the door corresponding to the card reader other than the card reader from which the ID information is read in the low level authentication time period, In the authentication time zone, security is not released for doors corresponding to card readers other than the card reader from which the ID information has been read, so that convenience can be improved without sacrificing security.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A design change is possible suitably in the range which does not deviate from the summary of this invention. For example, in the above-described embodiment, the security device 40 is provided in a distributed manner. However, the security device 40 includes a single security device 40 that can control all doors and card readers of the facility 10. Also good. Further, instead of the low-level authentication time zone table 42b, a normal level authentication time zone table that stores normal level authentication time zone information, which is information relating the start time and the end time of normal level authentication for each day of the week, is used. It may be a configuration. Moreover, the structure which changes the time until the door which opened automatically based on the security cancellation | release signal automatically closes according to the distance from an authentication place (it lengthens so that it is far) may be sufficient. In addition, when using a door with an electric lock instead of a door that is an automatic door, the security device 40 sends a security setting signal (locking signal) to the door with an electric lock after a lapse of a certain time after transmitting the security release signal. It may be configured to transmit to the door and lock the door with the electric lock.
