[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved secret electric lock operating device and an electric locking/unlocking system using the same.

0002

[Prior Art] Recently, a secret electric lock operating device has been installed at the entrance, etc., and when a password is input using this operating device, the electric lock at the entrance is automatically unlocked and the door can be opened. Electric locking and unlocking systems have been developed. Figure 4
shows an example of the configuration of such an electric lock/unlock system, in which a secret electric lock operator 200 is installed on the gatepost of the entrance (not shown) to which the electric lock unit 100 is attached, and a password is installed inside the residence. A number setting device 300 is installed and these are connected by signal lines L100 and L101, and a power transformer 400 that steps down the AC power source is connected to the password setting device 300.

[0003] In such a system, a password setting switch (rotary switch) 300a on the setting device 300 side
If you set a 4-digit PIN in advance, it will be transmitted to the controller 200 side via the signal line L101, and when the PIN is input by operating the numeric keypad 200a of the controller 200, the input PIN will be set. The password is compared with the password set on the device 300 side, and when a match is determined, the unlock operation key 200b is operated. Then, an unlocking command signal is transmitted from the operating device 200 to the setting device 300 side via the signal line L101, and the setting device 300 receives the unlocking command signal and transmits the unlocking command signal to the electric lock unit 100 side via the signal line L100. A signal can be output to unlock the lock, and the lock status signal output from the electric lock unit 100 is transmitted through the signal line L100.
The signal is transmitted to the setting device 300 installed in the dwelling unit, and is displayed by driving a lock indicator light 300c or an unlock indicator light 300d. In addition to the secret electric lock operation device 200, electricity can also be generated by operating the lock/unlock operation key 300e provided on the setting device 300 or the operation key 500a of the electric lock display operation device 500 added to the setting device 300. In addition to being able to lock and unlock the lock unit 100, the lock status can also be displayed on the operating device 500 using a lock indicator light 500b and an unlock indicator light 500c. It can be controlled remotely, and when residents return home, they can immediately unlock the electric lock unit by operating the secret electric lock operator.

However, in such an electric locking/unlocking system, there is a risk that the secret operating device 200 is intentionally removed and the password is read by another person, and for this reason, a password setting device 300 installed inside the room is used to store the password. Since the settings are made on the side, the operating device 200 and the setting device 300 are inevitably separated, and a large number of signal lines L101 have to be laid between them, which is cumbersome to install. Wiring errors tend to occur, and improvements are desired. In the example,
The PIN number is 4 digits, and there are 4 signal lines that transmit the set PIN number for each digit as a BCD code, and 1 to 10.
In addition to the four signal lines that transmit switching signals for each digit up to 00, there are two power lines for supplying power,
A total of 12 wires, two signal wires for transmitting the unlocking signal, are required.

[0005]

[Problems to be Solved by the Invention] The present invention, proposed in view of the above circumstances, reduces the number of signal lines to be laid by providing a secret electric lock operating device with the function of a conventional password setting device. In addition, we have developed a secret electric lock operating device that prevents the password from being read by others by storing it in a rewritable manner in memory, which improves both workability and reliability, and the electric power using this device. The purpose is to provide a lock/unlock system.

[0006]

[Means for Solving the Problems] A secret electric lock operating device of the present invention proposed to achieve the above object includes a key operating section having at least a numeric keypad for inputting a password and an unlock key, and a password key. A registration mode for registering a number,
A mode switching means with a mode switching switch for switching between control modes for locking and unlocking operations, an electric lock unit for locking and unlocking the door, and a rewritable registration of the password entered using the numeric keypad. A multiplex signal line for connecting a memory unit to be connected to an electric lock display operating device that remotely controls locking and unlocking of the electric lock unit and displays the locking and unlocking status of the electric lock unit. a signal control unit, and when in registration mode, stores a password entered by the numeric keypad in the memory unit;
In the control mode, the password entered using the numeric keypad is input and compared with the password stored in the memory section, and when a match is determined, the lock drive control section is connected to the electric lock unit connected through the control line. and a signal processing unit that outputs an unlock signal through the electric lock unit and inputs a lock state detection signal from the electric lock unit connected via a signal line and sends it to the multiplex transmission control unit. The secret electric locking/unlocking system of the present invention proposed in claim 2 displays the locked/unlocked state of the electric lock unit on the secret electric lock operating device according to claim 1, In addition, an electric lock display and operation device installed on the indoor side, which is equipped with an operation switch for remotely locking and unlocking the electric lock unit, is connected via multiple signal lines.

[0007]

[Operation] In the secret electric lock operating device of the present invention, when the mode changeover switch is operated to switch to the registration mode, the password entered using the numeric keypad of the key operation section can be registered in the memory section. After this registration operation is completed,
When the mode selector switch is operated to switch to the control mode, the password entered using the numeric keypad is compared with the password registered in the memory section, and when a match is determined, the electric lock unit is unlocked.

Further, in the electric lock/unlock system of the present invention, the locked/unlocked state of the electric lock unit is inputted to the secret electric lock operating device via the signal line, processed by the signal processing unit, and then multiplexed. Since the signal is displayed by an electric lock display operating device installed indoors, the locked/unlocked status is not visible to outsiders and confidentiality is maintained. Furthermore, the electric lock unit can also be remotely controlled by the electric lock display operator.
