[0009]
As shown in FIG. 3, only the management number of the security area 1 is stored for each ID number, as shown in FIG. 3, instead of having the position information in the vicinity of the security area 1 corresponding to each ID number as the configuration of the management database 9. The data capacity can be reduced by having a management number of the security area 1 and position information in the vicinity of the security area 1 as separate files.
[0010]
(Operation)
Next, the operation of the security electronic lock system according to the embodiment of the present invention will be described with reference to FIG. First, a card registered in advance by a person who wishes to enter the room is passed by an ID number extraction unit 3 installed near the entrance of the security area 1 and an ID number for each card recorded on the card is extracted, or an ID by a numeric keypad is used. When a person who wants to enter a number or the like or who wants to enter a room registers and puts human characteristics and an ID number in advance, personal authentication is performed based on the human characteristics and an ID number corresponding to the individual is extracted. (Step S1)
[0011]
Next, the electronic lock control unit 4 searches whether or not there is an ID number registered in advance as an entry permitter. (Step S2)
[0012]
Each time whether or not the ID number is registered in advance in step S2, the number of searches Ma is counted, and a usage fee corresponding to the number of searches Ma and a connection number Mb described later is held for a certain period.
[0013]
When the electronic lock control unit 4 determines that the ID number is an ID number registered in advance as a room entry permitter, the ID number is transmitted to the authentication server 8 of the authentication service company 7. (Step S3)
[0014]
On the other hand, when the electronic lock control unit 4 determines that the ID number is not an ID number registered in advance as an entry permitter, or when personal authentication cannot be performed, the electronic lock control unit 4 does not open the electronic lock 2, An alarm is output by a buzzer, a speaker, or a display. (Step S4)
[0015]
When the ID number is transmitted to the authentication server 8 in step S3, the authentication server 8 searches the management database in FIG. 2 or the first database in FIG. 3 for a previously registered telephone number corresponding to the ID number. If a corresponding telephone number is found, a position information transmission request is transmitted to the mobile phone having the telephone number via the mobile network 11. (Step S6)
[0016]
In step S5, the connection number Mb is counted each time a location information transmission request is transmitted to the mobile phone having the telephone number via the mobile network 11, and the usage fee corresponding to the search number Ma and the connection number Mb is constant. Hold for a period. Here, the reason for counting the number of searches Ma and the number of connections Mb separately is that a separate connection fee is required for connection to the mobile phone. Therefore, the number of searches Ma and the number of connections Mb are counted separately. This is because it is necessary to charge the security service applicant for a fee corresponding to the count number. In the charge billing method, a delivery destination such as an email to a security service applicant is registered in the authentication server in advance, and the usage fee information held in the authentication server 8 for a certain period is automatically transmitted to the email delivery destination. You can also.
[0017]
On the other hand, when there is no telephone number corresponding to the ID number, although not shown, the information indicating that there is no corresponding is transmitted to the electronic lock control unit 4, and the received electronic lock control unit 4 receives the error in step S4. Perform processing.
[0018]
In response to the location information transmission request transmitted in step S6, the cellular phone 5 corresponding to the telephone number measures the current location of the cellular phone by the GPS receiver 6 (step S7), and transmits the current location to the authentication server 8. To do. (Step S8)
[0019]
Here, GPS (Global Positioning System) is known as a satellite navigation system, and can be measured with an error of several meters to several tens of meters on the ground. It is widely used as a positioning method in navigation systems and the like. In this GPS, the latitude and longitude can be measured by three to four satellites, and the current altitude can be measured by four or more satellites.
[0020]
After transmitting the position information transmission request to the mobile phone 5 corresponding to the telephone number in step 7, if there is no response from the mobile phone 5 even after a predetermined time has passed, the authentication server 8 sends the electronic lock control unit 4. On the other hand, when a message indicating no response from the mobile phone 5 is transmitted and the electronic lock control unit 4 receives a message indicating no response from the mobile phone 5, the power of the mobile phone is supplied to a buzzer, a speaker or a display (not shown). Is not forgotten to be turned on, or a warning is output whether the GPS receiver 6 is not forgotten to connect.
[0021]
When the current location of the mobile phone 5 is transmitted to the authentication server 8 in step 8, the authentication server 8 obtains location information in the vicinity of the security area 1 corresponding to the ID number or the phone number from the management database 9 of FIG. 2 or FIG. It is extracted and compared with the current position of the mobile phone to determine whether it is in the vicinity. Here, in the case of the management database 9 of FIG. 3, the security area management number corresponding to the ID number or telephone number is extracted from the first database, and the vicinity of the security area 1 corresponding to the security area management number is extracted from the second database. The location information is extracted and compared with the current location of the mobile phone to determine whether it is in the vicinity. (Step 9)
[0022]
If the position in the vicinity of the security area 1 is close to the current position of the mobile phone, the result of authentication OK is transmitted to the electronic lock control unit 4. (Step 10)
[0023]
Here, as a method of determining whether or not it is a neighborhood, latitude N0, longitude E0, and altitude H0 are set in advance as positions in the vicinity of the security area 1, and current location information from the mobile phone 5 is longitude N1, latitude E1, and altitude H1. If there is a difference between the latitude, longitude, and altitude, all are within the predetermined threshold values αn, αe, αh, it is determined to be near, and if one is greater than the threshold values αn, αe, αh, it is determined not to be near. To do. That is, when | N0-N1 | <αn and | E0-E1 | <αe and | H0-H1 | <αh, it is determined to be near, and | N0-N1 | ≧ αn or | E0-E1 | ≧ αe or | H0 When −H1 | ≧ αh, it is determined not to be near. When checking the position of a detached house, it is possible to ignore the difference in altitude and determine whether it is near by latitude and longitude alone. Since information is also important information, it is necessary to consider altitude.
[0024]
Then, the electronic lock control unit 4 that has received the result of the authentication OK outputs the authentication OK to a buzzer, a speaker, or a display (not shown) and opens the electronic lock 2. (Step S11)
[0025]
On the other hand, if the position in the vicinity of the security area 1 and the position of the mobile phone 5 are not in the vicinity, it is determined that the card has been illegally accessed due to theft or forgery of cards, theft of ID numbers, misrecognition of personal authentication, etc. Information indicating that there has been unauthorized access and the location of the security area 1 is transmitted. (Step 12)
[0026]
At this time, an image of what is accessed is acquired by a camera or the like provided in the vicinity of the security area 1 (not shown) and stored in a memory or the like in the electronic lock control unit 4.
This image data is used to identify unauthorized access.
[0027]
As described above, in the first embodiment of the present invention, the electronic lock control unit 4 is described as being in the security area 1. However, the electronic lock control unit 4 is disposed in the authentication server 8 and the electronic key 2 is remotely controlled by the authentication server 8. It is also possible to adopt a configuration. In this case, since the authentication server 8 sends an electronic lock lock or release command to each electronic lock via the Internet 12, it is necessary to perform communication with high security.
[0028]
Further, in the security management system that enters a room by inputting a specific key, the management database 9 has the same ID number, but has a plurality of different telephone numbers and a plurality of different location information in the vicinity of the security area 1. In this case, the telephone number that matches the keyed ID number or the like and the position information in the vicinity of the security area 1 are all searched, and if any one pair of position information matches, the room entry permission is performed.
[0029]
