  A preferred embodiment of a building management system according to the present invention will be described below with reference to the drawings. The present invention is not limited to this, and the embodiments can be modified or omitted as appropriate within the scope of the invention.

Embodiment 1 FIG.
FIG. 1 is a block configuration diagram of a building management system according to Embodiment 1 of the present invention. In FIG. 1, a building 1 includes an in-building device 2 such as a lighting device or an air-conditioning device, and a building management system 3 that manages the in-building device 2. The building management system 3 includes a building management control unit 5, a barcode reading unit 6, a camera 7, and a terminal that manage and control the in-building device 2 via a control interface (hereinafter referred to as a control I / F) 4. For example, a telephone notification unit 8 that issues a notification to the mobile phone 20 is provided. The building management system 3 includes a mobile phone database 9 and a building equipment database 10.

  The mobile phone 20 is configured to be able to access a web server 30 of a building maintenance company. The web server 30 of the building maintenance company has a barcode generation unit 31 and a barcode display unit 33 that displays a barcode 32. Is provided.

  The building management system according to the first embodiment is configured as described above, and the mobile phone 20 accesses the Web server 30 of the building maintenance company and inputs necessary items such as the building equipment 2 to be controlled. The barcode generation unit 31 converts the input data into a barcode and causes the barcode display unit 33 to display the barcode 32. The displayed barcode 32 is read by a camera provided in the mobile phone 20. In addition to reading the barcode 32 displayed on the barcode display unit 33 with the camera of the mobile phone 20, the building maintenance company may send the barcode 32 to the mobile phone 20 by e-mail.

The user causes the camera 7 of the building management system 3 provided in the building 1 to read the following three types of barcodes from the mobile phone 20.
(1) Mobile phone serial number bar code (2) Building equipment serial number bar code (3) Building equipment setting / control bar code and bar code reading unit 6 of building management system 3 converts bar code 32 To the building management control unit 5.

  The building management control unit 5 takes out the mail address of the mobile phone from the mobile phone database 9 using the mobile phone serial number, generates a random number, and converts the random number into a barcode. Then, a random number barcode is transmitted from the telephone notification unit 8 to the mail address. The generated random number is stored in the building management control unit 5.

  The cellular phone 20 reads the received random number barcode into the camera 7 and compares the random number stored in the building management control unit 5 with the random number extracted from the received barcode 32. If the two match, the building equipment 2 is selected from the building equipment database 10 using the building equipment serial number captured in advance. After the selection, the building device 2 is controlled from the control I / F 4 according to the setting / control of the building device 2.

  It should be noted that the identification number of the building 1 is added to the barcode transmitted from the mobile phone 20 to the building management system 3 so that only the setting for the building 1 is accepted, or the building management system 3 is received from the mobile phone 20. It may be possible to further enhance the security of the barcode by adding an expiration date to the barcode to be transmitted and not accepting settings outside the expiration date.

  FIG. 2 is an example of a mobile phone database. In this example, the mobile phone 20 that enables setting / control of the in-building device 2 is registered. A unique serial number is assigned to the mobile phone 20 that enables setting / control of the in-building device 2 and is managed together with the telephone number and the mail address.

  FIG. 3 is an example of the building facility database 10. It consists of a building identification number for accepting only control of the own building 1 and a serial number assigned to each in-building device 2.

  4 and 5 are process flows of the building management system 3 according to the first embodiment. Preparations are made for using this building management system 3. As advance preparation, the mobile phone 20 that enables setting / control of the in-building device 2 is accessed to the Web server 30 of the building maintenance company, and a mobile phone number, an e-mail address, etc. are input to the Web server 30. Then, in the server 30 of the building maintenance company, for example, the cellular phone database 9 illustrated in FIG. 2 is created and the cellular phone serial number is converted into a barcode and stored in the cellular phone 20 that enables setting / control of the in-building device 2. Let me. (Step S1)

  The updated mobile phone database 9 is sent to the building management system 3 in real time. Further, separately, for example, the building facility database 10 illustrated in FIG. 3 needs to be created for the in-building equipment 2 to be set / controlled, and the created building facility database 10 is also sent to the building management system 3 in real time.

  Next, when actually setting / controlling the in-building device 2, the building maintenance company's Web server 30 is accessed from the mobile phone 20 registered in advance, and the in-building device 2 to be controlled on the Web screen is selected. And input the contents of setting / control. The building equipment serial number corresponding to the inputted building equipment 2 is extracted from the building equipment database 10 and converted into a bar code. Similarly, the contents of the setting / control are converted into a barcode. (Step S2)

  Next, the bar-coded data is taken into the mobile phone 20. The camera 7 of the building management system 3 is made to read the two types of barcodes fetched this time and the mobile phone serial number barcodes fetched in advance. (Step S3)

  Next, the building management system 3 generates a random number and converts it into a barcode. From the mobile phone serial number, a random number that has been bar-coded is sent to the mail address set in the mobile phone database 9 and stored at the same time. (Step S4)

  Next, the mobile phone 20 causes the camera 7 of the building management system 3 to capture the bar-coded data attached to the received mail. (Step S5)

  In the building management system 3, the stored random number is compared with the random number read by the barcode, and the designated setting / control is performed for the designated in-building device 2 only when they match. If they do not match, the setting / control is discarded. (Step S6)

  As described above, according to the building management system according to the first embodiment, the building management system that includes the reading unit that reads the barcode and performs various settings and controls is performed between the building management system 3 and the mobile phone 20. A building management system that enhances the security of the barcode can be obtained by having the barcode that has been subjected to mutual authentication read by both parties.
