Embodiment 1 FIG.
FIG. 1 is a diagram showing an example of the configuration of an access control system according to the present invention. Briefly describing the present invention, at least one terminal controller 2 that controls the locking and unlocking of each electric lock on the network 10 and the center device 1 that instructs these terminal controllers 2 to lock and unlock via the network 10 are provided. When the mobile terminal 5 and the network terminal device 8 are connected to the center device 1 via the network 10 and are permitted by terminal authentication in the center device 1, the terminal controller 2 is instructed to give an instruction to lock and unlock the electric lock. In the management system, each terminal controller 2 is provided with a switch 4 for unlocking communication, and when the switch 4 for unlocking communication is pressed, the communication with the center device 1 is confirmed and communication is not performed. It is characterized by unlocking the electric lock when it is confirmed. Access / exit management system Connected to a network 10 comprising a public line or the like, a center device 1 (comprising a computer, etc.), a plurality of terminal controllers 2 (also comprising computers, etc.) installed at remote locations, and the network 10 A network terminal 8 (network terminal device) composed of a computer or the like and a base station 6 (network terminal device) of the portable terminal 5 are connected. The terminal controller 2 is connected with an electric lock 3, an unlocking switch 4 when communication is not established, and a sensor 7 for detecting opening and closing of a door (not shown) to be controlled by the electric lock 3. A database 1a is stored which stores personal authentication data such as numbers, network addresses, ID numbers, passwords, etc. and registration data (permission table) of doors that are permitted to be unlocked for each individual.
[0009]
The locking and unlocking control of the electric lock 3 is performed by remote control through communication from the center device 1. The center device 1 can be accessed from a mobile terminal 5 such as a mobile phone or a network terminal 8 formed of a computer connected to the network 10. If you want to open the locked door, you can access the center device 1 from the mobile terminal 5, perform personal authentication with a phone number or PIN, and if you are authorized to unlock the door, you can communicate from the center device 1. An unlock message (instruction) is transmitted to the terminal controller 2 to unlock the electric lock 3.
[0010]
The processing flow of the center apparatus 1 at this time is shown in FIG. In FIG. 2, the center device 1 is waiting for access from, for example, the portable terminal 5 (which may be the network terminal 8, the same applies hereinafter), and the person who wants to open the door accesses the center device 1 and requests the door to be opened (step S21). There are many means for accessing the center device 1, such as NTT Docomo's i-mode, Internet access, and telephone control. Also, a human response by the operator is possible. When access from the mobile terminal 5 is received, it is judged whether or not the requested door can be unlocked by authenticating the individual with the telephone number or personal identification number of the mobile terminal (step S22).
[0011]
For this determination, a permission table in the database 1a in which doors permitted to be unlocked for each individual are registered in advance. If unlocking is not permitted in step S22, an access error is returned to the portable terminal 5 and the process is terminated (step S23). If unlocking is permitted in step S22, a communication message (instruction) for temporary unlocking is transmitted to the terminal controller 2 controlling the designated door (step S24). At this time, there is a case where the request from the portable terminal is continuous key unlocking or locking.
[0012]
Next, the processing of the terminal controller 2 when receiving a communication message for controlling the electric lock 3 from the center device 1 by communication will be described according to the processing flow shown in FIG. Waiting for reception of a communication message regarding control of the electric lock 3 from the center device 1 (step S31). When a communication message is received, the processing is divided into unlocking, locking, and temporary unlocking processes of the electric lock 3 according to the content of the message. In the case of an instruction to unlock the electric lock 3, the electric lock 3 is unlocked and the process ends (step S32). In the case of an instruction to lock the electric lock 3, the electric lock 3 is locked and the process ends (step S33).
[0013]
Steps S34 to S37 are processes for temporary unlocking (unlocking for a predetermined time (unlocking time)), unlocking the electric lock 3 (step S34), and then detecting opening / closing of a door (not shown) The sensor 7 and timer (not shown, which may be a program or hardware) may wait for the door to open within a predetermined time (unlocking time) (step S35). The electronic lock 3 is locked (step S37). If the door is not opened after a predetermined time in step S35, the electric lock 3 is locked (step S37). This is the remote electric lock control process when communication between the center apparatus 1 and the terminal controller 2 is normally performed.
[0014]
Next, the processing of the terminal controller 2 when the communication disconnection unlocking switch 4 connected to the terminal controller 2 is pressed will be described according to the processing flow shown in FIG. This switch 4 is installed outside the door and can be pressed at any time. Waiting for a signal to press the switch 4 to be input to the terminal controller 2 (step S41), when the switch 4 is pressed, a communication confirmation message determined in advance by the communication specifications is transmitted to the center apparatus 1 (step S42). .
[0015]
When the center apparatus 1 receives this communication message, it returns a response message to the control terminal 2 that has transmitted it. The terminal controller 2 waits for a response message to the transmitted confirmation message to be returned within a predetermined time (step S43). If there is a reply, pressing the switch 4 is ignored. If there is no response from the center device 1, the electric lock 3 is temporarily unlocked (step S44). Whether the processing in step S44 is temporarily unlocked or continuous unlocked is determined by operation.
[0016]
A process is added to the process of the terminal controller 2 of FIG. 4 to prevent the electric lock 3 from being unlocked due to mischief or the like. The processing of the terminal controller 2 in that case will be described according to the processing flow shown in FIG. In FIG. 5, it is determined that the switch 4 is pressed by a predetermined number of times within a predetermined time (step S51). This is a determination as to whether or not the pressing of the switch 4 is performed in a predetermined pattern and method. When the switch 4 is pressed by a predetermined operation, it is checked whether or not a predetermined time has elapsed since the time when the switch was temporarily unlocked by this series of processes (step S52). This is to reduce the possibility that a person who does not understand the operation of the terminal controller 2 will open the door by temporarily unlocking it by chance and not performing the same operation again even if the same operation is performed again. In addition, as will be described later, even if the door is accidentally unlocked by shortening the temporary unlocking time in the process of step S55, the door cannot be opened unless it is prepared to open the door.
[0017]
If the predetermined time has elapsed, a communication confirmation message determined in advance by the communication specifications is transmitted to the center apparatus 1 (step S53). When the center apparatus 1 receives this communication message, it returns a response message to the terminal controller 2 that has transmitted it. The terminal controller 2 waits for a response message to the confirmation message transmitted in step S53 to be returned within a predetermined time (step S54). If there is a reply, pressing the switch 4 is ignored. If there is no reply, it is assumed that a failure has occurred in the network 10, and the unlocking time is shortened (shorter than the temporary unlocking in FIG. 3) and temporarily unlocked (step S55). Next, the unlocked time is recorded (computer memory or register (not shown)), and the elapsed time can be processed in step S52 (step S56).
[0018]
For example, if the pressing time of the switch 4 is set to 10 seconds, the number of pressings is 3 times, the temporary unlocking time is set to 5 seconds, and the elapsed time is set to about 10 minutes in the process of FIG. The probability of unlocking and opening the door is very low. Considering that the unlocking process by the switch 4 is performed only when a failure originally occurs in the network, safety can be ensured.
[0019]
Further, when the unlocking time of the temporary unlocking is relatively long in step S55 or when the unlocking is performed without the time limit, the door (not shown) is further opened and closed as shown by the wavy line in FIG. Wait until the door is opened within a predetermined time (shorter than the unlocking time for temporary unlocking) by the sensor 7 and the timer to be detected (step S57). When the door is opened, the unlocking time for the temporary unlocking and until the door is closed Whichever comes first or until the door closes (step S58), then locks the electric lock 3 (step S59), and locks the electric lock 3 if the door does not open after a predetermined time. You may make it do.
[0020]
In this way, in an access control system that unlocks an electric lock remotely using a mobile terminal or the like, communication between the terminal controller and the center device is possible due to a network failure, a center device failure, a terminal controller failure, etc. Even if it is not possible, the door can be opened by unlocking the electric lock with an inexpensive switch installed in the terminal controller, so it is especially important to manage the access to unmanned facilities scattered in remote locations. Time loss such as returning to can be reduced. Moreover, it can be realized at low cost with a switch rather than an expensive device such as a numeric keypad device or a card verification device. Safety is also ensured by checking for network failures and not unlocking by simply pressing the switch.
[0021]
