Check the identification codes on modem 5 and modem 91,
After the connection is made, subsequent communication is performed via PC communication.

When it is confirmed that the modem 5 and the modem 91 are connected through personal computer communication, the central control device 3 of the terminal device l sends a terminal individual code to the central control device 92 of the central device 9. The central control unit 92 compares the terminal individual code with the terminal individual code registered in advance in the auxiliary storage device 93, and when the code is verified, sends a voice generation signal to the central control unit 3 of the terminal device 1. . Further, the central control device 92 of the central device 9 enters a state of receiving the personal identification code and the work code. The central control device 3 of the terminal device 1 sends the voice generation signal to the voice synthesis device 6 upon receiving the voice generation signal. Upon receiving this voice generation signal, the voice synthesizer 6 synthesizes a voice for operation guidance indicating that the personal identification code and work code should be entered into the operation panel 21, and also outputs the voice from the speaker 24 of the operation panel 21. send it out. In the above, when the central control unit W3 receives the voice generation signal through personal computer communication and sends it to the information input device 2, the information input device 2 enters the personal identification hood and work code reception state. Therefore, even while the above-mentioned voice is being generated, the person wishing to enter or leave the room can input the personal identification code and work code.

Next, when a person who wishes to enter (leave) an unmanned exchange or warehouse, etc. enters a personal identification code and a work code from the push button on the operation panel 21 of the information input device 2 of the terminal device 1, the code is converted into a binary coded decimal system. The converted code is sent by the code sending circuit 23 to the central control unit 3. The central control device 3 sends the input personal identification code and work hood to the central control device 92 of the central device 9 via personal computer communication. This central control device 92 stores the received personal identification coat and the personal identification coat in the work coat in the auxiliary storage device 9.

Register work hoods, etc. Furthermore, after registering the above-mentioned date, hour, person name, work hood, etc., the central control device 92 sends a key unlocking (locking) signal to the central control device 3 of the terminal device 1 through personal computer communication.

The central control device 3 activates the pulse signal generation and transmission circuit 7 upon receiving the key release (lock) signal. In response to this, the pulse signal generation and transmission circuit 7 sends a predetermined pulse signal to the pulse motor drive circuit 8.

When the pulse motor drive circuit 8 receives the pulse signal,
A pulse motor is driven, and the electric key is unlocked (locked) by the pulse motor. The pulse motor drive circuit 8 is
After unlocking (locking) the electric key, a key unlocking (locking) confirmation signal is sent to the central control device 3.

Upon receiving the key unlocking (locking) confirmation signal, the central control device 3 lights up the key unlocking (locking) confirmation lamp on the operation panel 21 (
(off) signal. Furthermore, the central control device 3 sends a voice generation signal indicating the completion of unlocking (locking) to the voice synthesis device 6, so that the person wishing to enter (leave) the room confirms that the key has been unlocked (locked) using the lamp 22 and the voice. Make it possible. Also,
Upon receiving the key unlocking (locking) confirmation signal, the central control device 3 sends a key unlocking (locking) confirmation signal to the central control device 92 through personal computer communication. Upon receiving the key unlock (lock) confirmation signal, the central control device 92 displays the above-mentioned registered date, hour, person name, work code, etc. on the display 94,
Even print it out.

As described above, this embodiment has excellent security because the terminal device 1 and the central device 9 exchange information (modulated signals) through personal computer communication using a public telephone line. In addition, since information such as a personal identification code and an action code is input, the personal name and work code are displayed on the display and printed out, thereby making it easier to manage entry and exit. In addition, in the past, the central device could not control multiple terminals, and the central device required manual intervention to exchange information using the PB double signal and send out audio from the central device, which took time to operate, and also made it difficult to However, in this embodiment, the central device 9 can communicate with a PC simultaneously with multiple terminal devices 1, so multiple terminal devices 1 can be controlled simultaneously, and voice and unlocking can be performed simultaneously. The (lock) signal is sent as a command signal, and the actual voice and unlocking (locking) drive is performed on the terminal device I side, so even if accesses are concentrated at the same time, waiting time is reduced.

Next, the operation of the communication/single automatic switching mode will be explained.

In the communication/single automatic switching mode, a person who wishes to enter (leave) an unmanned exchange or warehouse, etc. operates the operation panel 21 of the information input device 2 of the terminal device 1 installed at the entrance of the unmanned exchange or warehouse. When the password is input using the push button, the code converted by the binary coded decimal code sending circuit is sent to the central controller 3. The central control device 3 stores the manually entered password and the central control device 3 or the auxiliary storage device 31.
The PIN number registered in advance in
], etc., and sends a connection request to the modem 91 of the central unit 9 using the public telephone line 4 from the modem 5. When connection is not possible due to a failure of the central device 9 or a failure of the public telephone line 4, the central control device 3 of the terminal device 1 again sends the modem 5 to the central device 9 registered in advance in the central control device 3, etc. The telephone number is sent, and the modem 5 uses the public telephone line 4 to request connection to the modem 91 of the central unit 9. Once the connection is established, the modem 5 and modem 91 operate in the communication mode described above, confirm the identification code, establish a connection, and perform subsequent communication via personal computer communication, resulting in the operation of a communication mote.

If connection is not possible again due to a failure of the central device 9 or a failure of the public telephone line 4, the central control device 3 of the terminal device 1 automatically switches the terminal device 1 from the communication mode to the standalone mode, and the voice synthesizer 6 Sends a sound generation signal to. If a person wishes to enter (or leave) an unmanned exchange or warehouse, etc., the person confirms that the user has switched to the solo mode using a voice synthesized from the voice generated signal, and then the system is installed at the entrance of the unmanned exchange or warehouse, etc. The emergency password is input using the push buttons on the operation panel 21 of the information input device 2. In response to this, the converted code is sent to the central control unit 3 by the binary coded 10 quasi code sending circuit 23. The central control device 3 is
The input emergency password is compared with the emergency password registered in advance in the central control device 3 or the auxiliary storage device 31, and once the emergency password is verified, a voice generation signal is sent to the voice synthesizer. As a result, the information input device 2 enters the emergency personal identification coat and work code receiving state. Next, when a person who wishes to enter (or leave) an unmanned exchange or warehouse enters his or her emergency personal identification coat and work coat using the push buttons on the operation panel 21, the binary code sending circuit 2
2, the converted code is sent to the central control unit 3.

The central control device 3 compares the input emergency personal identification code and work code with the emergency personal identification code and work code registered in advance in the central control device 3 or the auxiliary storage device 31, etc. The pulse signal generation and transmission circuit 7 is activated only when the pulse signal is generated. Pulse signal generation and transmission circuit 7
sends a pulse signal to the pulse motor drive circuit 8.

The pulse motor drive circuit 8 receives this pulse signal and drives the pulse motor, and the electric key of the circuit is unlocked (locked) by the operation of the pulse motor. This key unlocks (locks)
After the completion of the process, the pulse motor drive circuit 8 is unlocked (locked).
A confirmation signal is sent to the central controller 3. The central control device 3 is
Upon reception of the key unlocking (locking) confirmation signal, a key unlocking (locking) confirmation lamp lighting (unlighting) signal is sent to the operation panel 21, and a voice generation signal is sent to the speech synthesizer 6. Thereby, a person who wishes to enter (leave) the room can confirm whether the key is unlocked (locked) by the lamp 22 and by voice. The central control device 3 automatically switches the terminal device 1 from the standalone mode to the communication mode upon receiving the key unlocking (locking) confirmation signal. As a result, the information input device W2 enters an input waiting state, preparing for recovery from a failure of the central device 9, a failure of the public telephone line 4, or the like.

In this embodiment, the terminal device 1 is connected to the central control device 3.
．． It has a built-in auxiliary storage device 31, a voice synthesizer 6, etc., and can operate independently, and can generate pulse signals and drive a pulse motor under the control of the terminal device 1 from the central device 9 or even when the terminal device 1 is alone. By doing this, the key can be unlocked (locked), so if the terminal device 1 and the central device 9 cannot be connected via PC communication due to a failure of the central device or a failure of the public telephone line, the terminal device 1 By automatically operating independently, the key can be unlocked (locked) and reliability can be increased.

Next, a description will be given of an operation for changing a password, etc. (hereinafter referred to as a password) used for verification.

First, when changing the password of the terminal device 1 from the central device 9, the supervisor inputs the telephone number of the terminal device 1 by typing on the central device 9. The central control device 92 of the central device 9 sends the telephone number of the terminal device 1 to the modem 91, and the modem 91 requests the modem 5 of the terminal device 1 to connect using the public telephone line 4. The modem 5 and modem 91 confirm their identification codes, establish a connection, and perform subsequent communication via personal computer communication. When it is confirmed that the modem 5 and the modem 91 are connected through personal computer communication, the central control device 3 of the terminal device 1 sends the terminal individual food to the central control device 92 of the central device 9. The central control device 92 compares the terminal individual code sent from the central device 3 with the terminal individual code registered in advance in the auxiliary storage device 93, and displays the current PIN and confirmation information on the display 94 only when the verification is successful. It will be displayed and waiting for input. The supervisor inputs the new PIN number by typing when the confirmation information is displayed, and the central controller 92 confirms and registers the input information, and also sends the new PIN number to the central controller 3 of the terminal device 1 through PC communication. send. The central control device 3 stores the sent new password and sends a change completion signal back to the central control device 92. Central control device 9
In step 2, a change completion indication is displayed on the display 94. From now on, the new PIN will be used as the current PIN.

When changing the password from the terminal device 1, a display device (not shown) is connected. A person who wishes to change his/her password inputs information on changing his/her password by typing on the central controller 3. As a result, the central control device 3 displays the current password on the display device and enters an input waiting state, and the person who wishes to change the password inputs the new password by typing. Central control device 3
stores the input password, and displays the current password, new password, and change completion on the display device. From now on, use your new PIN as your current PIN.

In this way, in this embodiment, the password (including emergency passwords) of the terminal device 1 can be easily changed by typing on the central device 9 or by typing on the terminal device 1. Security is ensured by changing the password separately.

Similarly, the personal identification hood and work code can be easily changed by typing on the central device 9, so it becomes impossible to verify anything other than the specific personal identification code, which prevents unauthorized use by anyone other than the person scheduled to work. can.

Incidentally, in the above, it is naturally possible to change the password on the central device 9 side at the same time by the terminal equipment operator's typing operation. As described above, the present invention can be applied in various ways and can take various embodiments in accordance with its gist.

[Effects of the Invention] As is clear from the above explanation, according to the information communication and monitoring device of the present invention, entry/exit management can be performed by communicating verification information regarding a person requesting unlocking of a terminal device to the central device in real time. Since it is now possible to do this in real time, it is no longer necessary to carry the keys of multiple unmanned exchange stations when carrying out construction work and various maintenance tasks, etc., and it is no longer necessary to carry the keys of multiple unmanned exchange stations when carrying out construction work and various maintenance tasks. The huge amount of time required to manage entry and exit for re-arrangement and wide-area maintenance will be reduced, making daily work more efficient.

In addition, by monitoring cases where the terminal device cannot be connected to the central device and allowing it to operate independently, if the terminal device is normal by using an uninterruptible power supply, etc., it is possible to detect a failure of the central device or a failure of the public telephone line. It is possible to deal with such cases.

In addition, it is possible to easily change the settings of the verification means for those who wish to enter and exit the terminal device and the central device. For example, by changing the PIN number by month, two days, or day of the week, or by changing the personal identification code and work code, Security can be ensured and unauthorized use by anyone other than the person scheduled to perform the work can be prevented.
