Abstract
The invention discloses safe and convenient rapid input equipment based on a biological characteristic recognition technology. The device does not have one or more physical or virtual keyboards, and only has one exposed fingerprint identification module, so that when different fingerprints of one or more persons are pressed down, different texts or functions (keys or key combinations) represented by the fingerprints can be sent to an upper computer.
Description
Technical Field
The present invention relates to accessories for personal computers, including personal tablet devices, mobile phones, etc., and in particular to an input device.
Background
Personal computers (including personal tablet devices, mobile phones, etc.) all have standard input devices: the keyboard may be a physical keyboard or may be a virtual keyboard on a touch screen.
The keyboard is used for inputting arbitrary text content including a plurality of languages. When we use the keyboard to input some special contents (such as password, ID card number, bank card number, email address, mailing address, etc.), not only the input is tedious (text is long, such as address), error is easy (such as ID card number, bank card number, etc.), but also there is a peeping risk (such as password, etc.), especially on non-private computers or mobile devices.
Disclosure of Invention
The invention aims to provide a safe and convenient rapid input device based on a biological characteristic recognition technology, as shown in fig. 1. The device does not have one or more physical or virtual keyboards, and only has one exposed fingerprint identification module, so that when different fingerprints of one or more persons are pressed down, different texts or functions (keys or key combinations) represented by the fingerprints can be sent to an upper computer.
1. On the equipment, the fingerprint of the user and the corresponding text content are input at one time;
2. connecting the device with a personal computer (including personal tablet devices, mobile phones, etc.) through a USB cable or Bluetooth and simulating the device as a keyboard (an HID device);
3. by clicking different fingers on a fingerprint identification module on the device, after the device identification is confirmed, different text contents (such as passwords, identification card numbers, bank card numbers, email addresses, mailing addresses and the like) or functions (such as media keys) are quickly and automatically input into a personal computer (including personal tablet devices, mobile phones and the like).
In order to achieve the above purpose, the following technical scheme is adopted:
as shown in fig. 2, the device comprises a device body, wherein a control circuit, a rechargeable battery and a USB charging/data interface are respectively arranged in the device body, and the device is characterized in that the control circuit comprises a main control module, a fingerprint identification module electrically connected to the main control module, a wireless communication module (comprising a Wi-Fi module and a bluetooth module (BLE)) electrically connected to the main control module, and a power management module electrically connected to the main control module; a rechargeable battery electrically connected to the power management module; and the USB charging/data interfaces are respectively and electrically connected to the main control module and the power management module.
Working process
As in fig. 3, when the device is powered on, if it is not connected to a personal computer (including a personal tablet device, a mobile phone, etc.) or a power module via a USB cable, the device will declare itself to provide a BLEHID service (keyboard) and broadcast via a bluetooth module (BLE) for discovery and connection by the personal computer, etc. When the personal computer and the like find and connect the equipment, a user can press the finger on the fingerprint identification module of the equipment, the fingerprint identification module obtains fingerprint characteristics and compares the fingerprint characteristics with the fingerprint characteristics existing in the local fingerprint library, and the comparison result is transmitted to the main control module. And if the master control module receives the successfully identified fingerprint code, the master control module combines corresponding keys in the locally stored fingerprint/key combination library and sends a group of key information to a personal computer and the like through BLE HID service of a Bluetooth module (BLE).
As shown in fig. 4, when the Device is powered on, if connected to a personal computer (including a personal tablet Device, a mobile phone, etc.) through a USB cable, the Device will declare itself as a USB HID Device (keyboard), declare to provide BLE UART services (serial ports) and broadcast through a bluetooth module (BLE) for discovery and connection by the personal computer, etc. The user can press the finger at the fingerprint identification module of the device, the fingerprint identification module obtains the fingerprint characteristics and compares the fingerprint characteristics with the fingerprint characteristics existing in the local fingerprint library, and the comparison result is transmitted to the main control module. And if the main control module receives the successfully identified fingerprint code, the main control module combines corresponding keys in the locally stored fingerprint/key combination library and sends a group of key information to a personal computer and the like through a USB cable. When a personal computer or the like finds and connects to a serial port (BLE UART service) of the device, a user can configure the device on the personal computer or the like using a dedicated program, including: addition, deletion and modification of fingerprint/key combination library, connection setup (SSID and password) of local wireless lan, etc.
As shown in fig. 5, when the device is powered on, if the device is connected to the power module through the USB cable, the device will declare to provide the BLE UART service (serial port) and broadcast through the bluetooth module (BLE) for the personal computer or the like to find and connect, when the personal computer or the like finds and connects the serial port of the device (BLE UART service), the user can configure the device on the personal computer or the like using a dedicated program, including: addition, deletion and modification of fingerprint/key combination library, connection setup (SSID and password) of local wireless lan, etc.
Description of the drawings:
FIG. 1 is a schematic view of the external structure
FIG. 2 is a block diagram of the structure
The device of fig. 3 is connected with a personal computer or the like through bluetooth
The device of FIG. 4 is connected to a personal computer or the like via a USB cable
The device of fig. 5 is connected with the power module through a USB cable
In particular, when there is external power (connected to a personal computer or the like via a USB cable, or to a power supply module), and the user has set connection information (SSID and password) of the local wireless lan, the device will use this connection information to attempt to connect to the local wireless lan, if the connection is successful, the device will periodically access an update server on the internet and check the update information, if there is new device firmware, the device will download and automatically update. This function is not performed when battery power is used, and the purpose of saving power is achieved.
In particular, the device will automatically determine the insertion and connection mode (charging+data, charging only) of the USB cable, and adjust the working state of the device according to this: wireless keyboard, wired keyboard + wireless serial port (configurable state), or wireless serial port only (configurable state).
The foregoing description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, and other structures obtained by adopting the same or similar technical features as those of the foregoing embodiment of the present invention are all within the scope of the present invention.
