04). That is, when the client side mobile phone 2 or the portable personal computer 3 accesses the key management server 4 to request the borrowing of the key, the key management server 4 is requested to use the client side mobile phone 2 or mobile phone in advance. It is assumed that the personal computer 3 is a registered personal computer. Then, the key management server 4 uses the mobile terminal 2 that has accessed the terminal.
Alternatively, in order to determine whether or not the portable personal computer 3 has been registered in advance, predetermined information transmitted from the mobile phone 2 or the portable personal computer 3, that is, terminal information is accepted. The terminal information is not limited to a specific one, but is, for example, the telephone number of the mobile phone 2, a password or an ID given in advance for terminal approval.

When the predetermined terminal information is received,
It is determined whether the terminal approval is established (see step S206 in FIG. 3). That is, the establishment of the terminal approval is performed by determining whether the terminal information transmitted from the mobile phone 2 or the portable personal computer 3, which is the terminal on the client side, matches the preset information. ing. Therefore, step S20
In FIG. 6, if the terminal information matches, it is determined that the terminal approval has been established (in the case of YES), and while the processing proceeds to step S208 described below, if the terminal information does not match, the terminal approval is not established (NO). In the case of), a series of processing is ended. In step S208, the key management server 4 requests the client side to send the password and ID, and the information is received. Then, when the password and ID are received, it is determined whether the received password and ID match those set in advance (see step S210 in FIG. 3). If it is determined that the password and the ID match (YES), the process proceeds to step S212 described below, while if it is determined that the password and the ID do not match (NO). If)
In this case, this series of processing is once ended and then repeated from the beginning.

In step S212, the key management server 4 issues an instruction to open and close the door to the key storage control box 5 via the data communication unit 8 as the password and ID are confirmed to match. Becomes That is, a predetermined signal is wirelessly transmitted from the data communication unit 8 to the mobile phone base station 9 in response to a control signal from the key management server 4, and the mobile phone base station 9 accordingly responds to the key storage control box. 5, that is, the mobile phone 7 connected to the control unit 6.
Call to establish a communication line with it. as a result,
The data communication unit 8 is in a data communicable state with the control unit 6 of the key storage control box 5 via the mobile phone base station 9. Then, the control unit 6 is instructed by the key management server 4 to unlock the electric lock so that the door (not shown) of the key storage control box 5 cannot be manually opened. Next, the key management server 4 enters a state of accepting information transmitted from the key storage control box 5 as described later, receives predetermined information, and repeats a series of processes.

Next, the operation of the key storage control box 5 will be described with reference to FIG. When the process starts
First, it is determined whether the above-described door opening / closing instruction is received from the key management server 4 (see step S302 in FIG. 4), and when it is determined that there is no door opening / closing instruction (NO). In the case of), the series of processes is ended, and once the process returns to the main routine process (not shown), the process is repeated again from the beginning. On the other hand, when it is determined that there is an instruction to open / close the door (in the case of YES), Means that the process of step S304 described below is performed. That is, in step S304, the door (not shown) of the key storage control box 5 is manually opened and closed so that a person who wishes to borrow the key can take out the key from the key storage control box 5. At the same time, the measurement of the elapsed time from that point will be started. This elapsed time is measured until it is determined that the door (not shown) is closed (see step S306 in FIG. 4). That is, when it is determined that the door of the key storage control box 5 is closed (see step S306 in FIG. 4), a person who wishes to borrow the key returns the key to the key storage control box 5 and manually closes the door. As a result, the measurement of the elapsed time is ended (see step S308 in FIG. 4). Then, the door of the key storage control box 5 is electrically closed again, and predetermined information is transmitted to the key management server 4 (see step S310 in FIG. 4), and a series of After the processing is once performed, the processing is repeated again from the previous step S302. Here, as the predetermined information transmitted to the key management server 4, for example, the time measured by the processing of the previous steps S304 and S308, the management number given in advance to the key storage control box 5, etc. Is preferred.

Next, FIG. 1 and FIG. 5 regarding the real estate agent system utilizing the Internet in the second invention.
It will be described with reference to FIGS. First, a real estate agent system according to an embodiment of the present invention will be briefly described. As the so-called hardware in the real estate agency system according to the embodiment of the present invention, FIG. 1 shown as a configuration example of an unmanned key management system is shown.
Based on such a configuration, the following functions are further added. First, in addition to the function of the unmanned key management system described above, the key management server 4 in this real estate placement system makes it possible to browse on the Internet the website for browsing real estate properties to be placement targets. -A well-known so-called Web server function is added. In addition,
For this Web server function, a dedicated server may be newly provided separately. Further, the key storage control box 5 is provided with a temporary contract button, a return button, and an extension button (all of which are not shown), and as will be described later, the control section 6 determines whether the button is on or off. Processing is performed according to the result. Further, the key storage control box 5 is provided with an alarm function, and as will be described later, when the key is returned within a predetermined time and the provisional contract button or the return button is not pressed, the control unit 6

Under the above-mentioned preconditions, concrete operations of the real estate agency system will be described below.
First, the operation on the client side will be described with reference to FIG. First, the key management server 4 (or Web
Those who wish to browse the homepage where the placement real estate property provided by the management dedicated server) is posted,
It is premised that a browsing ID and password for browsing the home page have been issued in advance by a company that manages the home page. That is, in principle, the home page of the placement real estate property according to the embodiment of the present invention can be viewed only by a pre-registered person, and the reliability and security of the information provided for viewing are improved. Then, a person who desires to browse accesses the key management server 4 from the client-side mobile phone 2 or portable personal computer 3 via the Internet 1. As a result, the home page of the mediation real estate property is displayed on the mobile phone 2 or the mobile personal computer 3, and a predetermined browse request tag provided on the home page is clicked or a predetermined numerical value or symbol is displayed. To receive the browsing ID and password input request from the key management server 4, and accordingly enter the browsing ID and password previously given as described above to enter the browsing state. That is, thereafter, the mobile phone 2 or the portable personal computer 3 is in a state in which various data of the real estate property to be searched is displayed.

FIG. 5 shows a processing procedure in the mobile phone 2 or the portable personal computer 3 on the client side when the real estate property to be brokered as described above is browsed and there is a property desired to be visited. Hereinafter, the processing procedure will be described with reference to FIG. This series of processing is performed by the mobile phone 2 or the portable personal computer 3 when a property desired to be visited is found while browsing the home page of the mediation real estate property.
It is started by clicking a visit tag on the homepage or after sending a predetermined command, etc., and the desired visit property information is entered (see step S402 in FIG. 5). That is, the key management server 4
When a request for a visit is made on the homepage, the client is requested to input information about a desired property to visit. Here, as the predetermined visit desired property information, for example, the property number of the property desired to be visited, so-called personal information such as the name, address, and telephone number of the applicant, and the desired date and time of the visit are suitable. The property number is the number assigned to each property on the home page.

When the input of the desired visit information is completed and the registration tag of the desired visit information on the home page is clicked, the input data is transmitted to the key management server 4 (see step S404 in FIG. 5), and then , The confirmation information transmitted from the key management server 4 is received, and a series of processing is ended (step S40 in FIG. 5).
6). Here, the "confirmation information" means predetermined information transmitted from the key management server 4 to the client side in order to inform the client side that the previous tour request information has been received from the key management server 4. Then, specifically, for example, a tour ID and password necessary for a property tour, a mobile phone number on the client side, a property application number of a property desired to be visited, a desired date and time, and the like are suitable.

Next, a series of processing steps in the key management server 4 in response to a request for browsing the contents of the property posted on the home page of the placement real estate property from the client side will be described with reference to FIG. When the processing is started, it is determined whether or not a browsing request is made from the client side (see step S502 in FIG. 6), and if it is determined that the browsing is requested (YES), step S504 described below. On the other hand, if it is determined that there is no desire to browse (NO), the series of processes is ended. Since this series of processes is a subroutine process, after the completion of this subroutine process,
The processing returns to the main routine processing (not shown) once, and after the predetermined processing in the main routine, this subroutine processing is repeated again.

In step S504, the browsing ID and password (PW) transmitted from the client side.
When these data (first predetermined data) are received, it is determined whether or not the data matches the one stored in the key management server 4 ( (See step S508 in FIG. 6). If it is determined in step S506 that they match (YES), the process proceeds to step S508 described below, while if it is determined that they do not match (NO).
In the case of), a series of processing is ended. Next, in step S508, it is determined whether or not there is a request to visit from the client side, and if it is determined that there is a request to visit (YES), a registration request is made to the client side. (See step S510 in FIG. 6) On the other hand, when it is determined that there is no desire to visit (NO), the series of processes is ended. Here, the “registration request” means the mobile phone 2 or the mobile personal computer 3 on the client side.
For requesting to enter and register the desired visit property information, the "visit desired property information" is the first step S in FIG.
This is as described in 402.

Then, it is determined whether or not the above-described predetermined items have been input (see step S512 in FIG. 6), and if it is determined that the predetermined input has not been made (in the case of NO), When it is determined that the predetermined items have been input (YES) while the series of processing is completed, the confirmation information is transmitted to the client side (see step S514 in FIG. 6). That is, here, as the "confirmation information", for example, a visitor ID on the client side, a tour ID and a password (PW) required when actually visiting the real estate property, a mobile phone number on the client side, a tour The property number of the desired property, the desired date and time, etc. Next, the key management server 4 processes the home page of the placement real estate property,
A series of processing is completed (step S5 in FIG. 6).
16). That is, as described above, the homepage processing performed here corresponds to the fact that the visitor's request for the placement real estate property posted on the homepage has been registered, and the display portion of the corresponding real estate property is in the middle of a business negotiation. An appropriate tag to that effect is displayed so that tours and contract negotiations do not overlap.

Next, with respect to the real estate property for which the visit request is registered as described above, the processing procedure in the key management server 4 when the visit is actually performed will be described with reference to FIG. We will also explain the processing at the time of the visit on the client side. When the process starts
It is determined whether or not the visit request access is made from the client side (see step S602 in FIG. 7), and when it is determined that there is no visit request access (NO), a series of processes is ended. On the other hand, if it is determined that the visit request is accessed (YES), the client ID and password are requested to the client side (step S604 in FIG. 7).
reference). Although a flowchart is omitted for the processing procedure in the mobile phone 2 or the portable personal computer 3 on the client side at the time of the tour, as described above, the mobile phone 2 or the portable personal computer 3 is on the day of the tour.
By doing so, the key management server 4 is accessed via the Internet, and, for example, a visit request is made by clicking a visit request tag on the home page. Then, the key management server 4 requests the tour ID and password, so the tour ID and password (second predetermined data) are input and transmitted.

Next, it is determined whether or not the tour ID and password input from the client side match those issued by the key management server 4 (see step S606 in FIG. 7), and it is determined that they do not match. If it is (NO), a series of processing is ended, while if it is determined that they match (YES), the key storage control box is sent from the key management server 4 via the data communication unit 8. An instruction to open / close the door is issued to 5, and a series of processing is ended (see step S608 in FIG. 7). In the determination of step S606, whether or not the date and time the visit is desired in advance is also determined based on the data stored in the key management server 4, and together with the visit ID and the password. If they do not match, it is not determined that there is a match in step S606.

By the command from the data communication unit 8 connected to the key management server 4 as described above, the door (not shown) of the key storage control box 5 can be manually opened and closed, and the person who desires to observe the property himself or herself can open the door. You will be able to open the door, take out the key required to enter the property you are visiting inside, and use the key to enter inside the property and look inside.
Next, regarding the processing procedure in the key storage control box 5, FIG.
Will be described with reference to. When the processing is started, it is determined whether or not a door opening / closing instruction is issued from the key management server 4 (see step S802 in FIG. 9), and when it is determined that there is no opening / closing instruction (in the case of NO). Indicates that while the series of processing is terminated, it is determined that the opening / closing instruction is issued (YES
In this case), the control unit 6 manually opens and closes the door (not shown) of the key storage control box 5, and a person who wishes to borrow the key can take out the key from the key storage control box 5. This will be possible, and the measurement of the elapsed time from that point will be started (step S80 in FIG. 9).
4). Next, it is determined whether or not a temporary contract button (not shown) provided in the key storage control box 5 has been pressed (see step S806 in FIG. 9). This provisional contract button is provided as a button to be pressed when the visitor finishes the inspection of the property and returns the key to the key storage control box 5 when he / she has decided to make a contract for the property. It has been done. That is, if the visitor returns the key to the key storage control box 5 and presses the temporary contract button after manually closing the door, it is determined in step S806 that the temporary contract button has been pressed. It has become. Then, after it is determined that the temporary contract button has been pressed, the temporary contract data notifying that the key has been returned from the key storage control box 5 to the key management server 4 and the temporary contract button has been pressed. Is transmitted and a series of processing is ended (see step S808 in FIG. 9). The provisional contract button is provided outside the key storage control box 5, or when the door of the key storage control box 5 is opened by being provided inside the key storage control box 5, for example. It may be configured such that it can be pressed only.

On the other hand, if it is determined in step S806 that the temporary contract button has not been pressed (NO), the return button (not shown) provided in the key storage control box 5 has been pressed. Whether or not it will be determined (see step S810 in FIG. 9). As described above with respect to the configuration of the key storage control box 5, the key storage control box 5 is provided with an appropriate sensor inside the key storage control box 5 for detecting that the key has been returned. Even if only the temporary contract button is pressed without returning it, it is not judged that the temporary contract button has been pressed.In such a case,
It is determined that the temporary contract button has not been pressed. The return button (not shown) provided on the key storage control box 5 is for returning the key to the key storage control box 5 by a visitor who has finished viewing the property and is not willing to contract for the property. It is supposed to be pressed after the door is closed. That is, when the visitor returns the key to the key storage control box 5 and presses the return button after manually closing the door, it is determined in step S810 that the return button is pressed. ing. If it is determined that the return button has been pressed (YES), the key storage control box 5 returns to the key management server 4 that the key has been returned and the return button has been pressed. The return data to be notified is transmitted, and the series of processing is ended (see step S812 in FIG. 9). The above-mentioned return button is provided outside the key storage control box 5, and for example, when the door of the key storage control box 5 is closed,
The configuration may be such that the return button is automatically pressed.

If it is determined in step S810 that the return button has not been pressed (in the case of NO), it is determined whether or not the measurement result of the elapsed time from the previous step S804 exceeds a predetermined time. Will be determined (see step S814 in FIG. 9). Here,
The case where the return button is not pressed is included when the return button is pressed and the key is not returned, as in the case where the previous provisional contract button is not pressed. It is like this. Step S814
In, when it is determined that the predetermined time has not elapsed (in the case of NO), the process returns to the previous step S806 and the series of processes is repeated, while when it is determined that the predetermined time has elapsed. In the case of (YES), an alarm device (not shown) provided in the key storage control box 5 is operated by the control unit 6.
Will be sounded by (step S816 in FIG. 9).
reference). Here, the “predetermined time” is a time preset as a time for viewing the property. Also, "alarm"
Is provided in order to cause a visitor to sound when the predetermined time has elapsed, meaning that the time has passed.
Then, it is determined whether or not an extension button (not shown) provided in the key storage control box 5 has been pressed (see step S818 in FIG. 9), and when it is determined that the extension button has been pressed (YES) ), The next step S820
On the other hand, when it is determined that the extension button is not pressed (NO) while proceeding to the processing of step S
The process proceeds to step 822. Here, the "extension button" is for extending the tour time and stopping the operation of the alarm device when the preset time for property inspection has passed and the alarm device is sounded as described above. In the embodiment of the present invention, the pressing of the extension button is effective only once. That is,
Extension of viewing time is permitted only once.

Then, in step S820, it is determined whether or not the extension button is pressed for the first time. If it is determined that it is the first time (YES), the alarm generation is stopped and the previous step is executed. Returning to S804, the time measurement is started from the beginning, and thereafter, the above-described processing is repeated. On the other hand, in step S820,
When it is determined that it is not the first time (in the case of NO), the notification process for notifying the key management server 4 of the abnormality is performed (see step S822 in FIG. 9). FIG. 10 shows a specific processing procedure of this notification processing in the form of a subroutine flowchart, and this notification processing will be described below with reference to FIG. When the process is started, it is determined whether or not a predetermined time has passed since the alarm was started (see step S822a in FIG. 10), and when it is determined that the predetermined time has passed (in the case of YES), the key storage control is performed. It is determined whether or not a reset switch (reset SW) for alarm (not shown) provided in the box 5 is pressed (see step S822b in FIG. 10). The determination in step S822a is repeated until it is determined that the predetermined time has elapsed.

When it is determined in step S822b that the reset switch has been pressed (in the case of YES)
On the other hand, when it is determined that the reset switch has not been pressed even if the predetermined time has elapsed (in the case of NO), the key management server 4 is notified. Then, the notification process of the abnormal situation is performed (see step S822c in FIG. 10). That is, the data communication function of the mobile phone 7 connected to the control unit 6 transmits a predetermined packet indicating the abnormal situation to the key management server 4, and the series of processes is ended.

FIG. 11 shows the key storage control box 5 as described above.
Server 4 for key management when an abnormal situation is reported from
The processing procedure in FIG. 11 is shown as a subroutine flow chart, and its contents will be described below with reference to FIG. When the process is started, it is determined whether or not there is a notification from the key storage control box 5 to inform the abnormal situation (see step S902 in FIG. 11), and when it is determined that there is no notification (in the case of NO). Means that a series of processing is ended. On the other hand, when it is determined that there is an abnormal situation report (in the case of YES), the key management server 4 notifies the abnormality occurrence through the data communication unit 8 together with the number of the article in which the abnormality has occurred in advance. It is transmitted to the contracted security company (see step S904 in FIG. 11), and the series of processing is ended. In addition, the security company that receives the abnormality report from the key management server 4 can identify the property in which the abnormality has occurred by the property number,
It is possible to take necessary measures.

Next, a processing procedure in the key management server 4 when the visitor finishes the visit will be described with reference to FIG. When the processing is started, it is determined whether or not there is data transmission from the key storage control box 5 (see step S702 in FIG. 8), and when it is determined that there is no data transmission (in the case of NO), On the other hand, when it is determined that there is data transmission (YES) while the series of processing is finished,
