DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key management device for centrally managing keys used for entering and exiting each room of an office building at an entrance or a floor.

[0002]

2. Description of the Related Art FIG. 5 is a perspective view showing an external structure of a conventional key management device. In this figure, the key management device 1 includes a key storage unit (cylinder) corresponding to each room in a building.
2 ₁ , 2 ₂ ,... 2 ₁₂ are provided.
_1, 2 _2, the ... 2 _12, as shown in FIG. 6, the key holder with a key 3 is housed. When using the key management device 1, an ID card issued in advance for each room or person is used. The ID card is passed through the card reader 4, and a password is input from the keypad 5. If the contents of the ID card and the personal identification number are registered in advance, the display LED is turned on, the lock of the corresponding key storage unit 2 is released, and the key storage unit 2 can be pulled out.

Normally, a security sensor and a magnet switch (a device for detecting opening and closing of a door) for one line are connected to one room, and when a key 3 with a key holder is stored in a key storage unit 2. After the elapse of the delay time, the room using the key 3 with the key holder becomes alert, and the room is released after the elapse of the delay time from the time when the key 3 with the key holder is removed from the key storage unit 2. In addition, when there is a part commonly used by each room (common part), for example, as shown in FIG. 7, if there is a corridor (common part A, B, C) on each floor of the building, all rooms on each floor are While the keys 3 with key holders are stored in each of the key storage units 2, the corridor of the floor is in the alert state, and when at least one key 3 with the key holder is taken out, the alert state is released. It should be noted that the numerical values “1”, “2”,
“3”,... ”Indicate individual lines to be controlled (hereinafter referred to as“ individual lines ”).
Is defined in terms of hardware by wiring or the like.

FIG. 8 (a) shows FIG. 7 in a table. As shown in FIG. 8, a key (or key storage unit) and an individual line have a one-to-one relationship. Further, a group of individual lines allocated to a key having the same common unit is designated as a common unit line to be controlled (hereinafter, referred to as a common unit line). In this case, both the individual line and the common unit line are defined in terms of hardware for the corresponding key by wiring or the like. In the case of FIG. 7, the line assigned to the common part shared by the room groups using the individual lines “1” to “4” is designated as the common line A, and the room using the individual lines “5” to “8” is specified. The line provided to the shared portion commonly used by the group is designated as shared portion line B.

A line assigned to a common part commonly used by the room groups of the individual lines "9" to "12" is designated as a common part line C. Common section lines A to C
The security sensors and the like installed in the corridors and the like on the 1st to 3rd floors are controlled and the lighting and the like are controlled. For example, when the key 1 is removed from the key storage unit 21, the common unit line A on the _first floor is controlled to release the security state of the security sensor installed in a corridor or the like and to light (one of the interlocking devices) Lights up.

[0006]

By the way, the above-mentioned conventional key management device has the following problems. (B) For example, when one key is used to control the individual lines on the first and second floors of a building, wiring processing such as tightening, crossing, and changing connection ports (change of hardware-related rules by wiring, etc.) is required. You need to do it. Since this work takes time, labor costs are high. In addition, since data registration must be performed to assign one key to at least two shared circuit lines, when a plurality of such keys are provided, data registration becomes complicated as well as wiring becomes complicated. Not suitable for practical use.

[0007] For example, as shown in FIG.
To control the individual lines of "1" to "4" for the common line A, and "5" for the common line B with the key 13
In the case of controlling the individual lines of “８” to “8”, it is necessary to change the hardware specification such as wiring. In this case, data registration for assigning the key 13 to both of the common unit lines A and B is required. Similarly, as shown in FIG.
When controlling the individual lines of “5” to “8” for the common unit line B by using the key 14, “1” to
In addition to controlling the individual line of “4” and controlling the individual lines of “9” to “12” with respect to the common unit line C, a change in hardware specifications such as wiring is required. Also in this case, data registration for assigning the key 14 to both of the shared unit lines A and C is required.

[0008] The case where a plurality of floors are controlled with one key is, for example, the case where a plurality of floors are cleaned. In this case, the cleaning company in charge of cleaning the 1F and 2F of the building is 1
It will have a key that can control both F and 2F. Note that a master key can play the role of all keys, and a submaster key can play a role of a plurality of keys, not the whole.

[0009] For example, the owner of the key 15 enters and exits the route indicated by the dotted line in FIG. 9, that is, enters and exits the rooms of the individual lines “3” and “7” and passes through the common part of the common part lines A and B. When only the access is permitted, the shared section data must be set as shown in FIG. 10, and also in this case, the individual line "3",
The hardware wiring process is performed for “7”. That is, when the key 15 controls the “3” individual line for the common unit line A and the “7” individual line for the common unit line B, hardware wiring processing is required.

(B) In switching the alert state of each line, only one delay time can be set for one key storage unit 2. Therefore, for example, in the former case, FIG.
With the key 15 permitted the path indicated by the dotted line, the security state of the common unit A on the first floor is released after a lapse of a certain time from the time when the key 15 is taken out from the key management device. Then, the alert state of the individual line 7 is also released. For this reason, even if the holder of the key 15 is on the first floor, the alert on the second floor is released, so that the 2
Intrusion into F cannot be detected. The case of sequentially entering and exiting a plurality of sections includes the case where a cleaning person cleans and the case where a security patrol person patrols. Naturally, unlike the case where employees who use the tenant in the building enter and exit their own tenants, they will enter and exit multiple sections sequentially, so if you release alerts at the permitted section at once, you will be lacking caution Will be generated.

As described above, in the conventional key management device, when a line is arbitrarily set as an object to be controlled by each key irrespective of an individual line or a common part, the line is closed, crossed, and connected. It is necessary to perform a wiring process such as a change, so that the work is time-consuming and labor costs are high. In addition, since only one delay time can be set for one key storage unit 2, a partition that cannot be warned with a key capable of controlling a plurality of lines may occur, or a delay control by a tenant employee or a cleaning staff may be distinguished. There was something I could not do.

Therefore, according to the present invention, when any line is set as an object to be controlled by each key irrespective of an individual line or a common unit, the line can be easily set without the need for wiring processing. It is another object of the present invention to provide a key management device which can set a delay time of a line assigned to each key storage unit which is a control source of the line.

[0013]

The concept of the present invention will be described below. Each key is controlled individually,
Any of the common parts can be specified arbitrarily from existing lines. Using a host computer or key input means, an input for designating an individual line and a common line is made in correspondence with each key. For example, when the setting is made in the same manner as in FIG. 8A, an individual line and a common line are designated for each key as shown in FIG. 3A. After the designation is completed, the result is as shown in FIG. FIG. 3 (c)
Is an example in which a plurality of keys are specified. In this example, for the key 13, the individual lines "1" to "8" are designated, and the shared unit lines A and B are designated. Also key 14
, The individual lines “1” to “4” and “9” to “1”
"2" is specified, and the shared unit lines A and C are specified.
In FIG. 3 (c), the keys 1 to 12 can be operated by the registration data specifying the hardware specification of the individual line and the common unit as in the conventional case.
3 and 14 can be realized only by the means of the present invention.

Therefore, the individual line and the common unit line can be arbitrarily designated corresponding to each key by the host computer or the key input means, so that it is not necessary to perform wiring processing such as tightening, crossing, and changing the connection port. In addition, the workability is improved and the inspection is facilitated, and the labor cost can be reduced. Further, it is easy to change the assignment when a section is added due to a section change, an extension or the like.

Further, a plurality of individual lines or shared unit lines can be designated for one key, so that a plurality of submaster keys can be handled. Furthermore, since a plurality of sub-master keys can be operated, it is not necessary for the user to carry a large number of keys or to move between each room and the key storage device for taking in and out. In this case, since a detailed consideration has not been given to the operation of the sub-master key, a dedicated storage section is provided in the apparatus in addition to a general key storage section. In addition, since the line designation can be arbitrarily changed by rewriting data, the key storage location can be changed at any time, thereby improving security.

In addition, when a line is designated, a delay time can be set for each key storage unit serving as a control source for each line. Therefore, a delay time can be set for each line for a key capable of controlling a plurality of lines, so that even when a person in charge of cleaning or security patrol enters and exits a plurality of sections sequentially, the delay time is set in the direction of travel. Is set to be delayed, the unguarded section can be eliminated, and the security is improved.

According to the first aspect of the present invention, there is provided a key management apparatus comprising: a plurality of key storage units for storing a plurality of keys;
Individual lines or individual lines assigned to each room on each floor of the building consisting of the plurality of keys and the plurality of floors based on the designated information
Is optional for common area lines assigned to common areas such as corridors
On the basis of the contents designated by the designation means and the presence / absence of a key in each of the plurality of key storage units, to alert / not alert common rooms such as rooms or corridors on each floor of the building based on the presence or absence of a key. And a control means for controlling a caution or interlocking device.

The key management device according to the second aspect of the present invention
The designation means can designate a plurality of or arbitrary lines from the existing lines including the common part for one key storage unit. According to a third aspect of the present invention, in the key management device, the designation unit can set a delay time for each of the key storage units that are control sources designated for one line. This is to perform alert / unwatch or control of the interlocking device immediately after the delay time elapses for the line for which the delay time is set. A key management device according to a fourth aspect of the present invention further comprises an input unit for inputting specification information output from an external device, wherein the specification unit specifies a line based on the specification information input by the input unit. Things.

B. Operation of Key Management Apparatus FIG. 4 is a flowchart showing a line designation operation of the key management apparatus 9. First, it is determined in step S10 whether or not the line designation mode has been selected. In this determination, when it is determined that the line designation mode has been selected, the process proceeds to step S12, and it is determined whether or not a key number has been input. In this determination, if it is determined that there is no key number input, step S1
Repeat 2. On the other hand, if it is determined that a key number has been input, the process proceeds to step S14, and the input key number is temporarily stored. After performing the processing of step S14,
Proceeding to step S16, it is determined whether there is an input of an individual line. In this determination, if it is determined that there is an input of an individual line, the process proceeds to step S18, and the input individual line is temporarily stored. On the other hand, when it is determined that there is no input of the individual line, step S16 is repeated.

After the input individual line is temporarily stored, the flow advances to step S20 to determine whether there is an input for setting a delay time. In this determination, when it is determined that there is an input for setting the delay time, the process proceeds to step S22, and the delay time is temporarily stored. This delay time corresponds to the individual line temporarily stored in step S18. After temporarily storing the delay time, the process proceeds to step S24. On the other hand, when it is determined that there is no input for setting the delay time, the process directly proceeds to step S24.

In step S24, it is determined whether there is an input of a common line. In this determination, if it is determined that there is an input of the shared section line, the process proceeds to step S26,
This shared section line is temporarily stored. On the other hand, when it is determined that there is no input of the common line, step S24 is repeated. After temporarily storing the input common unit line, the process proceeds to step S28, and it is determined whether there is an input for setting a delay time. In this determination, when it is determined that there is an input for setting the delay time, the process proceeds to step S30, and the input delay time is temporarily stored. This delay time corresponds to the shared line temporarily stored in step S26. After temporarily storing the delay time, the process proceeds to step S32. On the other hand, if it is determined that there is no input for setting the delay time, the process proceeds to step S3.
Proceed to 2.

In step S32, it is determined whether or not there is another line designation. That is, it is determined whether or not there are a plurality of line designations for one key. In this determination, if it is determined that there is another designation, the process returns to step S16. On the other hand, if it is determined that there is no other designation, the process proceeds to step S34, and the setting of the temporarily stored key number, the individual line, the delay time of the individual line, the common unit line and the common unit line delay time is performed. It is determined whether or not it is OK. In this determination, when it is determined that each setting is OK, the process proceeds to step S36, and each setting value is written to the memory 28. On the other hand, if it is determined that each setting is NG, the process returns to step S12. After determining that each setting is OK, writing each setting value to the memory 28, the process returns to step S10.

As described above, in this embodiment, when the line designation command is supplied from the host computer 30, the mode is switched to the line designation mode.
If there is at least one designation of an individual line or a shared line assigned to the key, it is stored, and if a delay time is designated for the designated line, it is temporarily stored. After this processing is completed, when a write command to the memory 28 is supplied, each temporarily stored set value is written to the memory 28. When a command to perform the normal mode is supplied, the mode is switched to the normal mode,
Thereafter, based on the registration data written in the memory 28, control for each individual line and the common unit line is performed.

Therefore, the host computer 30 can arbitrarily designate an individual line and a common unit line corresponding to each key, so that wiring processing such as tightening, crossing, and changing connection ports is not required. As a result, the inspection is facilitated and labor costs can be reduced.
Further, since a plurality of individual lines or shared unit lines can be designated for one key, a plurality of submaster keys can be handled. Furthermore, since a plurality of sub-master keys can be operated, it is not necessary for the user to carry a large number of keys or to move between each room and the key storage device for taking in and out. In addition, since the line designation can be arbitrarily changed by rewriting data, the key storage location can be changed at any time, thereby improving security.

Further, since a delay time can be set for each line with respect to a key capable of controlling a plurality of lines, even if a person in charge of cleaning or security patrol enters and exits a plurality of sections sequentially, If the setting is made such that the delay time can be delayed, the unguarded section can be eliminated, and the security is improved. In the above embodiment, the individual line, the shared line, and the delay time are specified by the host computer 30, but the key input unit and the display unit are provided in the key management device, and the key management device itself is provided. Alternatively, the line may be designated.
