On the display unit 125, the storage number, the destination, and the key state are displayed in association with each other. For example, when the storage number "1", the destination "store A", and the key status are displayed in green on the display unit 125, the key 200 used in the destination "store A" is the key corresponding to the storage number "1". It shows that it is normally stored in the locking portion 123a.

The communication interface 114 may be any one provided with an information communication interface, and is, for example, a network cable insertion port, a wireless communication transmission / reception function unit, or the like. The communication interface 114, GPS 124, and speaker 127 are arranged on the right side surface of the key box main body 130, but this is only an example and may be in other positions.

The processor 111, RAM 112, HDD 113, etc. are realized by the control board provided inside the key box main body 130, but the illustration is omitted.
Next, the setting information of the second embodiment will be described with reference to FIG. FIG. 6 is a diagram showing an example of setting information of the second embodiment.

The setting information 600 is information for setting the storage number of the key 200, the position information of the destination (destination) where the key 200 is used, and the like in the key management device 100. The setting information 600 is information that is input by a staff member on the server 300, stored in a storage unit such as HDD 313 of the server 300, and then stored in a storage unit such as HDD 113 of the key management device 100. The clerk inputs the order of the destinations for guarding the key management device 100 as a storage number. In addition, the clerk shall input the destination matching the destination order (storage number) of the police as the destination, and input the key identification information of the key 200 used at the destination in association with each other.

The key management device 100 displays the storage number display unit 125a and the destination display unit 125b based on the setting information 600. Further, the key management device 100 determines the key identification information read by the tag reader 122 based on the setting information 600, and lights the key status display unit 125c.

The setting information 600 includes items of storage number, destination, key identification information, and location information. The storage number of the key 200 is registered in the storage number item. The storage number is the order of the destinations of the security route of the key management device 100, and is also the order of the keys 200 used at the destination (destination). For example, the key identification information of the key 200 used first and the storage number "1" are associated and stored in the setting information 600. In the destination item, the name of the destination (destination) of the security route of the key management device 100 is registered. In the key identification information item, the key identification information of the key 200 used at the destination is registered. The location information items include latitude and longitude items. The latitude of the destination is registered in the latitude item. The destination longitude is registered in the longitude item.

Here, the entry included in the setting information 600 will be described. For example, the setting information 600 includes information such as "1" for the storage number, "Store A" for the destination, "H023" for the key identification information, "35.6812" for the latitude of the location information, and "139.7671" for the longitude. Is registered. This indicates that the name of the destination (storage number "1") to go to No. 1 is "Store A" and the key identification information of the key 200 used in the store A is "H023". It also indicates that the destination store A is a facility located at latitude "35.6812" and longitude "139.7671".

In FIG. 6, the setting information 600 includes entries from the storage numbers "1" to "8", and the value at the end of the storage number is "8", but this is only an example. The clerk registers the entry with the storage number "1" as the information corresponding to the first destination of the security route, and the entry with the number at the end of the storage number as the information corresponding to the last destination of the security route. The clerk can determine the storage number according to the number of destinations (destination) included in the security route of the key management device 100. The information shown in FIG. 6 is only an example, and the setting information 600 may be information including one or more entries associated with the storage number, the destination, the key identification information, and the location information.

Further, in the setting information 600, the same destination may be registered for different storage numbers. For example, a case where there are two safes in branch office D and each safe is unlocked and locked using different keys 200 will be described. When the order of the police of the branch office D is next to the "branch office C (storage number" 3 ")", the destinations of the storage numbers "4" and "5" are both registered as "branch office D". Further, different key identification information "J429" and "I904" are registered in the entries corresponding to the storage numbers "4" and "5", respectively. Further, the same position information (latitude "35.6809", longitude "139.7729") is registered in the entries corresponding to the storage numbers "4" and "5".

Next, the sequence of the second embodiment will be described with reference to FIG. FIG. 7 is a diagram showing an example of a sequence of the server and the key management device of the second embodiment.
The sequence executed by the server 300 and the key management device 100 will be described. The processing executed by the server 300 is executed by the server control unit 310 (processor 311). The process executed by the key management device 100 is executed by the key management control unit 110 (processor 111).

The server 300 is in a state where information communication with the key management device 100 is possible via the network 410, receives input from a staff member, and starts processing.
[Step S11] The server 300 receives the input of the setting information 600 from the staff via the input device 315a, stores it in a storage unit such as the HDD 313, and transmits the setting information 600 to the key management device 100.

[Step S12] The key management device 100 receives the setting information 600 and stores it in a storage unit such as the HDD 113.
[Step S13] The key management device 100 unlocks the key box lid 131 and unlocks the key locking portion 123. The key management device 100 accepts the key 200 stored by the staff.

[Step S14] The key management device 100 reads the key identification information from the tag 201 included in the key 200 by the tag reader 122.
[Step S15] The key management device 100 displays the storage number, the destination, and the storage state of the key 200 on the display unit 125 based on the information read from the tag 201 and the setting information 600 in step S14.

The process of this step will be described in more detail. First, the key management device 100 displays the storage number and the destination included in the setting information 600 on the storage number display unit 125a and the destination display unit 125b in the order of the storage number. Next, the key management device 100 compares the key identification information read by the tag reader 122a with the key identification information “H023” of the entry of the storage number “1” of the setting information 600. When the key identification information matches as a result of comparison, the key management device 100 lights the key status display unit 125c corresponding to the storage number display unit 125a displaying the storage number “1” in green. When the key identification information does not match as a result of comparison, the key management device 100 lights the key status display unit 125c corresponding to the storage number display unit 125a displaying the storage number “1” in red. When the key identification information cannot be read by the tag reader 122a, the key management device 100 turns off the key status display unit 125c corresponding to the storage number display unit 125a displaying the storage number "1".

In this way, in the key management device 100, the keys 200 stored after the storage number "2" also have the key identification information "green" when the key identification information matches, "red" when the key identification information does not match, and the key identification information. If it cannot be read, the key 200 is indicated on the key status display unit 125c by turning off the light. The lighting method for indicating the key state in the key management device 100 is an example, and lighting or blinking may be performed in other colors.

By visually observing the lighting state (green lighting, red lighting, extinguishing) of the key status display unit 125c, the clerk can confirm whether or not the key 200 is correctly stored based on the setting information 600.

[Step S16] The key management device 100 determines whether or not the storage number and the key identification information match. In other words, the key management device 100 determines whether or not the storage number and the key identification information registered in the setting information 600 match the key identification information read from the tag 201 using the tag reader 122. For example, the key management device 100 compares the key identification information “H023” of the entry of the storage number “1” of the setting information 600 with the key identification information read by the tag reader 122a, and determines whether or not they match. The key management device 100 compares the key identification information “K095” of the entry with the storage number “2” with the key identification information read by the tag reader 122b, and determines whether or not they match. Similarly, the key management device 100 determines whether or not the key identification information of the setting information 600 and the key identification information read by the tag reader 122c, ... Are consistent with each other after the storage number "3".

When the key identification information is inconsistent (in the case of step S16 “No”), the key management device 100 transmits the inconsistent storage number and the key identification information to the server 300, and proceeds to step S13. When the key identification information is consistent (in the case of step S16 “Yes”), the key management device 100 transmits to the server 300 that the storage is completed, and proceeds to step S18.

[Step S17] The server 300 displays the information received from the key management device 100 and the instruction based on the received information on the display 314a. For example, when the server 300 receives the inconsistent storage number and key identification information, the server 300 displays an instruction "Please store the key correctly" on the display 314a together with the received information. In addition, when the server 300 receives the notification that the storage is completed, the server 300 is disconnected from the network after confirming the display of the first destination after locking the key box lid and "The key storage has been completed correctly." , Please send me a message. ”Is displayed on the display 314a.

[Step S18] The key management device 100 locks the key locking unit 123.
[Step S19] The key management device 100 detects that the key box lid 131 is closed, and locks the lid lock portion 121.

[Step S20] The key management device 100 highlights the first destination and ends the process. Specifically, the key management device 100 displays the storage number “1” and the corresponding destination in the display unit 125 differently from the other displays, and ends the process.

Next, the key management process during the security of the second embodiment will be described with reference to FIG. FIG. 8 is a diagram showing an example of a flowchart of the key management process during the security of the second embodiment.
The key management process during guarding is a process of unlocking and locking the key box lid 131 and the key locking unit 123 and displaying the display unit 125 based on the setting information 600 while the key management device 100 is guarding.

The key management control unit 110 (processor 311) of the key management device 100 stores the setting information 600 in the storage unit as described with reference to FIG. 7, stores the key 200, and stores the key locking unit 123 and the key box lid 131. After locking and lighting the first destination, the key management process during police is executed.

[Step S31] The key management control unit 110 acquires the position information of the current position via the GPS 124, and determines whether or not it matches the position information of the current destination included in the setting information 600.

Here, the current destination is the destination corresponding to the storage number "1" included in the setting information 600 when this step is executed for the first time. Next, when this step is executed, the current destination is the destination corresponding to the storage number "2" in the following order. Similarly, for the storage number "3" and thereafter, the current destination is determined according to the order of the storage numbers registered in the setting information 600. As an exception, when the same position information is continuous in the setting information 600, the position information next to the continuous position information is acquired as the position information of the current destination. For example, in the setting information 600, the destination next to the destination "branch office D" (storage number "4" and "5") is "financial institution E" (storage number "6").

Further, the determination of the match of the position information may be determined as a match as long as it is within a predetermined error range (for example, + -2%), and is not an exact match with the position information included in the setting information 600. It is also good.

[Step S32] The key management control unit 110 accepts the unlocking process of the lid lock unit 121. In other words, the key management control unit 110 receives from the staff a password for authenticating the unlocking process of the lid lock unit 121 via the input unit 126.

[Step S33] The key management control unit 110 determines whether or not the unlocking process is appropriate. The key management control unit 110 determines that the unlocking process is appropriate when the password stored in the storage unit such as the HDD 113 in advance matches the password input from the input unit 126 (when the authentication results match). Then proceed to step S34. If the passwords do not match, the key management control unit 110 determines that the unlocking process is inappropriate, and returns to step S32.

[Step S34] The key management control unit 110 unlocks the lid lock unit 121.
[Step S35] The key management control unit 110 unlocks the key locking unit 123 of the storage number corresponding to the position information of the current position. The key management control unit 110 unlocks two or more key locking units 123 when there are two or more storage numbers corresponding to the current position. For example, when the position information of the current position matches the position information of the destination "branch office D", the key management control unit 110 includes key chains included in the key locking units 123d and 123e corresponding to the storage numbers "4" and "5". To unlock each.

The clerk takes out the stored key 200, unlocks the deposit / withdrawal machine and the safe at the destination (destination), and performs the work of collecting cash. The clerk shall store the key 200 used after the cash collection work is completed in the key management device 100.

[Step S36] The key management control unit 110 reads the key identification information from the tag 201 included in the key 200 via the tag reader 122.
[Step S37] The key management control unit 110 lights the key status display unit 125c based on the key identification information read in step S36 and the setting information 600 stored in the storage unit. When the key management control unit 110 compares and matches the storage number and key identification information registered in the setting information 600 with the key identification information read by the tag reader 122 corresponding to the storage number, the key state corresponding to the storage number is matched. The display unit 125c is lit in green. The key management control unit 110 compares the storage number and key identification information registered in the setting information 600 with the key identification information read by the tag reader 122, and if they do not match, the key status display unit 125c corresponding to the storage number is displayed in red. Lights up. When the key identification information cannot be read by the tag reader 122, the key management device 100 turns off the key status display unit 125c corresponding to the storage number.

[Step S38] The key management control unit 110 determines whether or not the key 200 is correctly stored. When the key management control unit 110 compares and matches the storage number and key identification information registered in the setting information 600 with the key identification information read by the tag reader 122 corresponding to the identification number, the key 200 is correctly stored. Judged as The key management control unit 110 proceeds to step S40 when the key 200 is correctly stored, and proceeds to step S39 when the key 200 is not stored correctly (when the key identification information does not match).

[Step S39] The key management control unit 110 outputs an error voice from the speaker 127. For example, if the key identification information of the key 200 stored in the storage number "1" does not match, the key management control unit 110 says, "The key of the storage number 1 does not match. Please store the key correctly." Instruct the speaker 127 to output the voice.

[Step S40] The key management control unit 110 locks the key locking unit 123 and the key box lid 131. When two or more key locking units 123 are unlocked, the key management control unit 110 locks two or more key locking units 123. Further, the key management device 100 detects that the key box lid 131 is closed (detects that the key box lid 131 is closed), and locks the lid lock portion 121.

[Step S41] The key management control unit 110 determines whether or not the next destination exists. When the value obtained by adding "1" to the storage number corresponding to the current position information is smaller than the value at the end of the storage number, the key management control unit 110 determines that the next destination exists. When the value obtained by adding "1" to the storage number corresponding to the current position information is larger than the value at the end of the storage number, the key management control unit 110 determines that the next destination does not exist.

The key management control unit 110 is different when the position information corresponding to the current storage number and the position information corresponding to the next storage number are the same (when the same position information is continuous in the setting information 600). Search for location information in ascending order of storage number. The key management control unit 110 searches the setting information 600, and if there is no position information different from the current position information after the current storage number, it determines that the next destination does not exist. The key management control unit 110 searches the setting information 600, and if there is position information different from the position information of the current destination after the current storage number, it determines that the next destination exists.

The key management control unit 110 proceeds to step S42 when the next destination exists, and ends the process when the next destination does not exist.
At the end of the process, the key management control unit 110 can keep the state in which the setting information 600 is encrypted and stored in the storage unit. As a result, the key management control unit 110 can prepare for the case where the security route registered in the setting information 600 is used again and maintain the security of the setting information 600.

Further, at the end of the process, the key management control unit 110 can receive the data erasure instruction via the communication interface 114 and erase the setting information 600 from the storage unit. As a result, the key management control unit 110 can maintain the security of the setting information 600 by erasing the data when the security route registered in the setting information 600 is not used again.

[Step S42] The key management control unit 110 highlights the next destination of the storage number display unit 125a and the destination display unit 125b, normally displays the current destination, and proceeds to step S31. By highlighting the next destination, the key management control unit 110 alerts the destination and reduces errors in the police route.

For example, it is assumed that the current destination is "store A", and the storage number "1" and the destination "store A" corresponding to the current destination are highlighted in the storage number display unit 125a and the destination display unit 125b. .. Based on the setting information 600, the key management control unit 110 displays the storage number "2" and the destination "financial institution B" corresponding to the next destination "financial institution B" on the storage number display unit 125a and the destination display unit 125b. Instruct to highlight the aspect. The key management control unit 110 instructs the storage number display unit 125a and the destination display unit 125b to normally display the display mode of the storage number "1" and the destination "store A" corresponding to the current destination "store A". Then proceed to step S31.

In this way, the key management control unit 110 determines whether or not to accept the unlocking of the key box lid 131 based on the current position. As a result, the key management device 100 can prevent the key 200 from being stolen or lost by restricting the removal of the key 200 from a place other than the destination.

Further, the key management control unit 110 unlocks only the key locking unit 123 corresponding to the destination, and locks the key locking unit 123 and the key box lid 131 after confirming that the key 200 is correctly stored. As a result, the key management device 100 can take out only the key 200 used at the destination, and cannot take out the other keys 200. Further, the key management device 100 can prevent a mistake when storing the key 200 by displaying the storage state indicating whether or not the key 200 is correctly stored on the key state display unit 125c.

In this way, the key management device 100 unlocks and locks the key box lid 131 and the key locking unit 123 based on the current position acquired via GPS 124, and the display unit 125 can display the destination and the key state. As a result, the key management device 100 avoids human error such as a mistake of the key 200 by the staff, and even if a storage error of the key 200 occurs, the display unit 125 notifies the storage state of the key 200. Therefore, the staff can be alerted.

In this way, the key management device 100 can improve the security when the key 200 is sent and used.
