Further, the search result of the management server 7 by this notification is notified to the user.

  The management server 7 is a computer that establishes a homepage on the Internet, and executes user authentication processing based on whether the access is made by a user who can use the property management system 1 through access by the personal computer 8 or the like. In addition, by this user authentication, a predetermined menu screen is provided for a user who can use the property management system 1 to execute a series of search processes.

  FIG. 1 is a flowchart showing the processing procedure of this search processing. When the user is correctly authenticated, the management server 7 moves from step SP1 to step SP2, provides a predetermined input screen to the personal computer 8, and inputs a date and time range to be searched by user input on the input screen. As a result, the management server 7 accepts an input of the date and time when it is considered that the user has lost his belongings.

  Subsequently, the management server 7 moves to step SP3, where any of the belonging detection devices 2 to 5 related to the management of the management server 7 is detected according to the user ID and search range of the user related to this access. The notification of the detection result recorded by the apparatus is instructed. Therefore, in this case, for example, when the user A designates the search range December 11 for the record in FIG. 4 and instructs the search, the management server 7 possesses the user A's belongings on the December 11 The detection result is inquired, and the corresponding inventory detection device returns the detection result of the PDA, mobile phone, employee ID card, and credit card on December 11th.

  As a result, the management server 7 proceeds to step SP4 and determines whether or not there is a record related to the user ID based on a response from the corresponding belonging detection device. If there is a record, the process proceeds from step SP4 to step SP4. After moving to SP5 and acquiring this record, the process moves to step SP6. On the other hand, if there is no record corresponding to the belonging detection device, the process moves directly from step SP4 to step SP6.

  In this step SP6, the management server 7 determines whether or not the inquiry has been completed for all the belonging detection devices. If a negative result is obtained here, the management server 7 moves to step SP7, where the inquiry destination is the next belonging detection. After setting the device, the process returns to step SP3. As a result, the management server 7 sequentially inquires and acquires records of the user's belongings related to access to all the belonging detection devices managed by the management server 7.

  In the acquisition of these belonging detection results, the management server 7 acquires the time at which the belongings are detected, and when the inquiry is completed for all the belonging detection devices, an affirmative result is obtained in step SP6. In step SP8, the acquired detection results are arranged in a time series according to the detection time, and the arrangement in the time series is displayed by the computer 8.

  FIG. 5 is a plan view showing an example of this display. In this example, a PDA, a mobile phone, an employee ID card, and a credit card are carried while leaving the home and entering the office. On the other hand, when leaving the office, only the PDA, the employee ID card, and the credit card were detected, and it can be seen that the mobile phone was lost in the office. In addition, after leaving the office and before entering the restaurant, even if you carry a PDA, employee ID card, or credit card, when you leave the restaurant, only the PDA and employee ID card are detected. It turns out that the credit card was lost in the restaurant. Also, when you get in the vehicle after leaving the restaurant, you carry your PDA and employee ID card, but when you get off the vehicle, you only carry your PDA and you forget to put your employee ID card on the vehicle. I know that. As a result, the management server 7 aggregates the detection results of the belonging detection device in time series and notifies the user of the location where the user has lost his belongings.

  By the way, in the history of belongings detected in this way, there may be a case where the user intentionally leaves the product on the go. In addition, there may be a case where the user actually has not carried it from the beginning, and the user thinks that he / she has carried away from home 10. In this way, the management server 7 displays the history on the computer 8 in this way, accepts the operation of the presence / absence of the loss by the user, determines whether or not the user has selected the lost menu in the subsequent step SP9, If a negative result is obtained in step SP10, the process proceeds to step SP10 and the processing procedure is terminated.

  On the other hand, if an affirmative result is obtained in step SP9, the management server 7 moves from step SP9 to step SP11, and the user decides whether or not to execute a lost item process by displaying a predetermined menu screen on the computer 8. Accept selection. Here, lost property processing is processing to contact the relevant organizations to find lost property and avoid damage caused by lost property. If a negative result is obtained here, the management server 7 moves from step SP11 to step SP10 and ends this processing procedure. On the other hand, if an affirmative result is obtained in step SP11, the management server 7 moves to step SP12 and executes the lost item processing, and then moves to step SP10 and ends this processing procedure.

  As a result, if the lost item is, for example, a credit card, the management server 7 contacts the card company so that the credit card cannot be used, and arranges for a reissue of the credit card. If this card is, for example, a commuter pass, contact the relevant transportation facility so that this commuter pass cannot be used, and arrange for a reissue of the commuter pass. On the other hand, in the case of a mobile phone or PDA and lost in a specific facility such as a restaurant, for example, the facility is contacted to confirm the presence or absence of a lost item.
