Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an electric lock device that is unlocked by inputting a password.

<Prior art> A keyboard switch is installed outside the entrance of a house or an office, and an electric lock can be unlocked by entering a password consisting of a combination of numbers or letters using the keyboard. Electric locking devices are well known, and the password can be configured using, for example, a four-digit number.
, a number is used. This PIN number must be used every time you open the door from the outside, or you must manually enter the 4-digit number each time you don't need to lock the door other than when you go out or sleep, that is, when you are normally at home. Opening the door is extremely cumbersome, wastes effort, and provides a potential trespasser with many opportunities to monitor the resident's attempts to unlock the door and decipher the password. The problem is that it is easy to invite

<Aspects of the Invention> The present invention focuses on these problems, and aims to provide an electric lock device that can be unlocked by simple keyboard operations when at home, without using the regular 1IN8i identification number. It is something that has been done.

<Structure of the Invention> In order to achieve the above object, the present invention is provided with a home unlock switch on the keyboard, which is effective only in the home mode and causes the control unit to output an unlock signal in response to an input operation. It is a feature.

As this at-home unlocking switch, a dedicated switch may be installed on the keypad Y, but it is also possible to use one of the key switches for inputting a PIN number.In the latter case, a normal PIN code In addition to the number, you can set a shortened PIN number to be used when in home mode, and use this to unlock the door. This abbreviated password may be selected from one or two of the numbers, letters, symbols, etc. on the keyboard switch. With such a configuration, the lock can be unlocked with one or two input operations, greatly improving operability.

<Example> Next, the present invention will be specifically described with reference to an illustrated example.

Figure 1 is a block diagram, in which 1 is a keyboard switch installed outside the entrance/exit door, 2 is an electric lock installed inside the door, 3 is a controller installed at a suitable location in the room, and 4 is a microcomputer. 5 is a PIN number setting section,
Reference numeral 6 indicates an unlocking switch setting section, 7 indicates a mode selection section, and 8 indicates a power supply section. The controller 3 is normally provided with other alarm devices, various indicator lights, unlocking switches, etc., but their explanation will be omitted.

The password setting section 5 is configured with a switch for setting a four-digit number, for example, and is used to set a commonly used password, and the unlocking switch setting section 6 is configured to set a commonly used password. The switch is selected as the unlock switch when the user is at home.

The mode setting section 7 is for selecting either at-home mode or alert mode.

Next, the operation will be explained with reference to the flowchart shown in FIG.

The control section 4 constantly monitors the presence or absence of any key force from the keyboard switch 1, and if there is any key force, it checks the state of the mode setting section 7, ie, whether it is in the at-home mode or the alert mode.

In the case of alert mode, the key force is compared with the number set in the PIN setting section 5, and if they match, the digit data is advanced by one, and if all the key forces up to the fourth digit match, an unlock signal is sent. is output, and the electric lock 2 is unlocked.

When the mode setting section 7 is in the at-home mode, the key force is compared with the number or symbol (e.g. "*") specified in the unlocking switch setting section 6, and if they match, an unlocking signal is output. The operation of unlocking the electric lock 2 is also performed.

In this embodiment, as is clear from FIG. 2, in the case of at-home mode, a comparison is made with the number specified in the unlock switch setting section 6; however, even in the case of at-home mode, It is also possible to use a regular password to unlock the lock, and the number setting by the unlock switch setting section 6 is not limited to one digit, but can be a multiple digit that is easy to remember and repeat. It is also possible to set and use the number as a shortened PIN number. <Effects of the Invention> As is clear from the above explanation, the present invention reduces the number of times the keyboard 1t switch is operated during the home mode. It can be unlocked, which has the advantage of improving operability when you are at home without reducing security.

Claims (1)

[Claims] ■ A control unit that compares the number entered from the keyboard switch with a preset 1-ID ID number and issues an unlock signal if the two match. and an electric lock that is electrically unlocked by an unlocking signal from the control unit, the at-home lock is enabled only in the at-home mode and causes the control unit to output an unlocking signal in response to an input operation. An electric lock device characterized in that a lock switch is provided on a keyboard.
