Description

Quick key finding device

The present invention relates to a key, and more particularly to a quick key finding device.

According to the door locks commonly found in public places such as schools and offices, they are usually commissioned by the same manufacturer. The door locks are all the same. The keys are roughly the same in appearance. The difference lies in the nicks on the key handles. Convenient, often the keychains are made into a whole string for easy use, but when you want to open the door, a bunch of keys can't tell which key it is. You have to spend time with a key to try it out, or in each one. The key number is attached to the key, but the key is used for a long time. The sticker is easy to be dirty or dropped, which makes it unrecognizable. It is not a long-term solution. Therefore, it is very difficult to find the corresponding key from a series of keys, and it needs to be consumed. a lot of time.

It can be seen that there are still many shortcomings in the above-mentioned household items, which is not a good designer and needs to be improved.

In view of the shortcomings derived from the above-mentioned customary keys, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in researching and developing the rapid key finding device.

The object of the present invention is to provide a fast key finding device, which is compared with an authentication code provided on a key by a wireless authentication device. When the authentication code is met, the visual display device provided on the key will be illuminated or Blinks to quickly find the key relative to the door lock.

A quick key finding device capable of achieving the above object includes: a door lock; a key, a setting device, an authentication code, a solar battery, and a visual display device, wherein the visual display device is used The setting device sets a visual display information of a conditional rule, and the authentication code can be driven by the microprocessor of the wireless authentication device to drive the solar cell to turn on the visual display device to use a preset condition rule as a reminding function; The authentication device is disposed on the door lock and electrically connected to a microprocessor, a setting device, a reading device, a visual display device and a power module, and the visual display device sets a visual display of the conditional rule by the setting device Information, the reading device receives an authentication code, and provides a microprocessor read and verification (Examination and Verification), so that the power module turns on the visual display device to use a preset condition rule as a reminder function.

1 is a perspective view of a quick key finding device of the present invention; and FIG. 2 is a flow chart of the quick key finding device.

Referring to FIG. 1 and FIG. 2, the quick key searching device provided by the present invention mainly includes: the present invention relates to a quick key searching device, which is mainly provided with a setting device 21 on the door lock 1 and the key 2, 31, wherein the key 2 is provided with a setting device 21, 31, an authentication code, a solar battery 23, and a visual display device 24, 34, and the setting device 21, 31 and the authentication code 22, the solar battery 23, and The visual display devices 24 and 34 are electrically connected. The visual display devices 24 and 34 set a conditional display visual display information by the setting devices 21 and 31. The authentication code 22 can be read by the microprocessor 32 of the wireless authentication device 3. After the driving, the solar cell 23 is driven to turn on the visual display devices 24 and 34 as a reminder function by using a preset condition rule. The visual display device 24, 34 may be a plurality of LEDs, and the visual display device 24, 34 receives solar energy. After the battery 23 is driven, it will be constantly bright or blinking, or bright green for communication, bright red for non-passage, etc.; a wireless authentication device 3, which is disposed on the door lock 1 and A microprocessor 32, a setting device 21, 31, a reading device 33, a visual display device 24, 34 and a power module 35 are provided. The visual display device 24, 34 sets a condition by the setting device 21, 31. The visual display information of the rule, the reading device 33 receives an authentication code 22, and provides the microprocessor 32 for reading and checking. And certifying that the power module 35 turns on the visual display devices 24 and 34 as a reminder function by using a preset condition rule; that is, the above-mentioned parts of the quick key finding device of a preferred embodiment are provided by the author. The introduction of the components and their assembly methods, and then the use characteristics and advantages are described as follows: When the user wants to open a door in the house, the key 2 is first approached or touched by the door lock 1 provided on the door panel. The reading device 33 of the wireless authentication device 3 on the door lock 1 senses the authentication code 22 on the key 2, and the authentication code 22 is read by the microprocessor 32 of the wireless authentication device 3, and then inspected and authenticated to make the solar energy. The battery 23 turns on the visual display devices 24 and 34 on the key 2 as a reminder function according to a preset condition rule, and causes the power module 35 to turn on the visual display devices 24 and 34 on the door lock 1 by a preset condition rule. As a reminder function, when the authentication code 22 matches the authentication code 22 set by the microprocessor 32 in the key 2, the visual display devices 24, 34 provided on the key 2 will emit light or flash, whereby the user can Quickly find the corresponding door through the invention The key 2 of the door lock 1 on the board.

The user can change the authentication code 22 through the setting device 21, 31, generate a new set of authentication data by the authentication code 22, and receive the new authentication code 22 by the reading device 33 of the wireless authentication device 3. The authentication code 22 is read and verified by the microprocessor 32, and the power module 35 is turned on to the visual display device 24, 34 as a reminder function by using a preset condition rule, thereby changing the authentication code 22 on the key 2. To provide users who have long-term replacement of tenants, In order to prevent the old tenant from copying the authentication code 22 on the key 2, the illegal action is performed, so that the key 2 is more convenient and safe; the authentication code 22 can also be set as a tag (RFID), the wireless authentication. The reading device 33 of the device 3 can also be configured as a tag reading device 33 (RFID READER), which transmits data from a tag attached to the key 2 via a radio signal modulated by an electromagnetic field of a radio frequency. The reading device 33 reads and writes a label data by sensing the label of the key 2, and the label is read and verified by the microprocessor 32, and the power module 35 is turned on to the visual display device 24, 34 to preset.
