Description

Technical Field

Based on the IoT, wireless communications and cloud platforms enable data sharing and control between devices. This is the device interconnection solution.

The greatest advantage of device interconnection solutions is that they allow people to more conveniently manage and control their devices, while also enabling collaboration between devices, improving efficiency and enhancing the user experience.

[0003] When the current device interconnection solution is applied to biometric information collection, the back-end server is required to communicate with the front-end device and the collection device respectively. The front-end device sends a request message to the back-end server, and the back-end server then sends the request message to the collection device. After receiving the request message, the collection device collects the biometric information and returns the collected biometric information to the front-end device through the back-end server. This will cause the communication link between the front-end device and the collection device to be too long, the interaction process to be cumbersome, resulting in the overall communication speed to slow down and the service requirements to become higher.

[0036] To facilitate understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intervening elements can exist between them. In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance.

[0037] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0038] See also Figure 1 , the embodiment of the utility model provides a collection system, such as Figure 1 As shown, the acquisition system 100 includes an acquisition module 10 and a server 20 .

[0039] The collection module 10 is used to collect the user's biometric information, wherein the biometric information includes but is not limited to fingerprints, face, iris, palm prints and other information. In some embodiments, Figure 1 As shown, the acquisition module 10 includes a terminal device 11 and a acquisition device 12 .

[0040] Terminal device 11, serving as the front-end of collection system 100, is capable of implementing functions such as human-computer interaction, data collection, and data processing. Terminal device 11 is equipped with a collection plug-in, which is installed within the target application on terminal device 11 and is used to implement biometric information collection. When terminal device 11 runs the target application, the user can operate the collection plug-in to perform various operations. For example, the user can operate the collection plug-in to trigger a collection operation. A collection trigger operation is an operation that triggers the biometric information collection function through the collection plug-in, and the collection plug-in can respond to various user operations. Terminal devices 11 include, but are not limited to, electronic devices such as smartphones, laptops, and desktop computers.

[0041] The collection device 12 is communicatively connected to the terminal device 11, and is used to receive the collection signal sent by the collection plug-in through the terminal device 11 in response to the user's collection trigger operation. The collection signal is a signal used to instruct the collection device 12 to collect biometric information. The collection device 12 can respond to the collection signal, collect the user's biometric information and send the biometric information to the terminal device 11.

[0042] Since when collecting biometric information, the terminal device 11 does not need to communicate indirectly with the collection device 12 through the server 20, the terminal device 11 only needs to communicate directly with the collection device 12, thereby shortening the communication link, improving the overall communication speed, and helping to reduce service requirements.

[0043] The server 20 is in communication with the terminal device 11 and is configured to receive biometric information uploaded by the terminal device 11 and store the biometric information for subsequent access. In some embodiments, the server 20 may be a physical server or a logical server virtualized from multiple physical servers. In some embodiments, the server 20 may also be a server cluster consisting of multiple interconnected servers, with each functional module distributed across each server in the server cluster.

[0044] In some embodiments, see Figure 2 The acquisition device 12 includes an acquisition circuit 121 , a first interface circuit 122 and a controller 123 .

[0045] The collection circuit 121 is used to collect the user's biometric information.

[0046] The first interface circuit 122 is used to communicate with the terminal device 11. The communication connection here can be a wired communication connection. A wired communication connection refers to a connection method that uses tangible media such as metal wires and optical fibers to transmit information, such as a connection method that uses a USB cable to transmit information. The communication connection here can be a wireless communication connection. A wireless communication connection refers to a connection method that transmits information through radio waves or other wireless communication technologies, such as a connection method that transmits information through WiFi, Bluetooth, ZigBee, or mobile communications.

[0047] In some embodiments, the first interface circuit 122 is a wired interface circuit or a wireless interface circuit, wherein the wired interface circuit is an interface circuit for implementing a wired communication connection, and the wireless interface circuit is an interface circuit for implementing a wireless communication connection. When the first interface circuit 122 is connected to the terminal device 11 by wired communication, the first interface circuit 122 can be a wired interface circuit; when the first interface circuit 122 is connected to the terminal device 11 by wireless communication, the first interface circuit 122 can be a wireless interface circuit.

[0048] The controller 123 is electrically connected to the acquisition circuit 121 and the first interface circuit 122. When the first interface circuit 122 is in communication with the terminal device 11, the controller 123 can interact with the terminal device 11 through the first interface circuit 122, thereby sending and receiving data between the two devices. The controller 123 can control the acquisition circuit 121 to collect biometric information, obtain the biometric information collected by the acquisition circuit 121, and send the biometric information to the terminal device 11 through the first interface circuit 122.

[0049] In some embodiments, the controller 123 can be any general-purpose processor, a DSP (Digital Signal Processing), an FPGA (Field Programmable Gate Array), an ARM (Advanced RISC Machines) processor, an ASIC (Application Specific Integrated Circuit), a single-chip microcomputer or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of these components. In addition, the controller 123 can also be any conventional processor, controller, microcontroller, or state machine. The controller 123 can also be implemented as a combination of computing devices, such as a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in combination with a DSP, and / or any other such configuration.

[0050] In some embodiments, see Figure 3 The acquisition circuit 121 includes a collector 1211 and a signal processing circuit 1212 .

[0051] The collector 1211 is used to sense user biometrics and generate analog signals. User biometrics are physiological characteristics inherent to the human body, including but not limited to fingerprints, facial features, iris features, palm print features, etc. In some embodiments, the collector 1211 is a fingerprint sensor or an image sensor.

[0052] A fingerprint sensor is a sensor for sensing a user's fingerprint. In some embodiments, the fingerprint sensor includes an optical fingerprint sensor, a semiconductor capacitive sensor, a semiconductor thermal sensor, a semiconductor pressure sensor, an ultrasonic sensor, and a radio frequency (RF) sensor.

[0053] An optical fingerprint sensor uses optical principles to detect and identify fingerprints. Its operating principle is based on the optical properties of fingerprint texture and surface reflection. An optical fingerprint sensor consists of a light source and an optical lens. The light source emits light, which is focused by the optical lens and then illuminates the fingerprint surface. The uneven texture of the fingerprint surface causes light to reflect and refract, resulting in varying brightness and color distributions. The optical fingerprint sensor records these reflected and refracted light and converts it into an electrical signal. By detecting the brightness and color distribution of the light, the optical fingerprint sensor can accurately reconstruct fingerprint texture information.

[0054] Semiconductor capacitive sensors mainly use the principles of capacitance, electric field (also known as inductance), temperature, and pressure to collect fingerprint features.

[0055] Semiconductor thermistors use temperature differences to identify fingerprints. When a finger is placed on a semiconductor thermistor, the temperature difference between the fingerprint's ridges (raised areas) and valleys (concave areas) creates when they come into contact with the semiconductor thermistor. The temperature at the ridges approaches body temperature, while the temperature at the valleys approaches ambient temperature. The semiconductor thermistor quickly scans these temperature differences to identify the fingerprint's ridges and valleys. Specifically, the temperature difference between the ridges and the semiconductor thermistor is greater than the temperature difference between the valleys and the semiconductor thermistor. This difference is captured by the semiconductor thermistor and converted into an electrical signal.

[0056] The principle of semiconductor pressure sensors is primarily based on a combination of pressure sensing and capacitance (or inductance). The surface of a semiconductor pressure sensor consists of an array of elastic dielectric materials. When a finger presses against the surface of the semiconductor pressure sensor, the ridges (raised areas) of the fingerprint exert a downward force on the elastic dielectric, causing it to deform downward. Meanwhile, the valleys (concave areas) of the fingerprint do not contact or only slightly contact the elastic dielectric. These states of contact and non-contact (or slight contact) are converted into electrical signals by the circuitry within the semiconductor pressure sensor.

[0057] The ultrasonic sensor contains an ultrasonic transmitter module and an ultrasonic receiver module. The ultrasonic transmitter module is responsible for emitting high-frequency ultrasonic pulses. These ultrasonic pulses can penetrate the surface of objects, including the skin epidermis, and continue to propagate. When ultrasonic waves encounter interfaces of different materials, such as the ridges and valleys of a fingerprint, they are reflected. Because the ridges and valleys of a fingerprint differ in height and material, their reflection characteristics for ultrasonic waves are also different. The ridges (raised areas) of a fingerprint reflect more ultrasonic energy, while the valleys (concave areas) reflect less. The ultrasonic receiver module is responsible for receiving the ultrasonic pulses reflected from the fingerprint surface. These reflected waves contain information related to the fingerprint characteristics.

[0058] The principle of RF sensor is mainly to emit a small amount of radio frequency signal through the sensor itself, penetrate the epidermis of the finger to detect the inner layer of texture, and thus obtain the corresponding electrical signal.

[0059] An image sensor is a sensor used to sense a user's biometric characteristics using the photoelectric conversion function of a photoelectric device. Its main operating principle is to use the photoelectric conversion function of the photoelectric device to convert the light image on the photosensitive surface into an electrical signal proportional to the light image. In some embodiments, image sensors include but are not limited to CCD (Charge-Coupled Device) sensors, CMOS (Complementary Metal Oxide Semiconductor) sensors, CIS (Contact Image Sensor), ToF 3D Image Sensors (Time of Flight 3D Image Sensors), and TIS (Thermal Image Sensor).

[0060] In some embodiments, see Figure 4 The signal processing circuit 1212 includes a preamplifier circuit 12121 , a filter circuit 12122 and an analog-to-digital conversion circuit 12123 .

[0061] The preamplifier circuit 12121 is electrically connected to the collector 1211 and is configured to amplify the analog signal output by the collector 1211 to obtain an analog amplified signal. In some embodiments, the preamplifier circuit 12121 is an integrated operational amplifier.

[0062] Filter circuit 12122 is electrically connected to preamplifier circuit 12121 and is configured to filter the analog amplified signal output by preamplifier circuit 12121 to produce an analog filtered signal. Specifically, filter circuit 12122 is configured to filter out high-frequency noise and low-frequency interference from the analog amplified signal, thereby retaining valid signals related to fingerprint features. In some embodiments, filter circuit 12122 can be any type of filter circuit, including but not limited to low-pass filter circuits, high-pass filter circuits, and band-pass filter circuits.

[0063] The analog-to-digital conversion circuit 12123 is electrically connected to the filter circuit 12122 and the controller 123, respectively, and is configured to convert the analog filtered signal output by the filter circuit 12122 to obtain biometric information. It will be appreciated that this biometric information is a digital signal. Since the analog-to-digital conversion circuit 12123 can convert analog signals into digital signals, it facilitates digital signal processing by the controller 123.

[0064] In some embodiments, see Figure 5 The terminal device 11 includes a second interface circuit 111, a processor 112 and a wireless communication module 113.

[0065] The second interface circuit 111 is used to communicate with the acquisition device 12. The communication connection here can be a wired communication connection. A wired communication connection refers to a connection method that uses tangible media such as metal wires and optical fibers to transmit information, such as a connection method that uses a USB cable to transmit information. The communication connection here can be a wireless communication connection. A wireless communication connection refers to a connection method that transmits information through radio waves or other wireless communication technologies, such as a connection method that transmits information through WiFi, Bluetooth, ZigBee, or mobile communications.

[0066] In some embodiments, the second interface circuit 111 is a wired interface circuit or a wireless interface circuit. When the second interface circuit 111 is connected to the acquisition device 12 via wired communication, the second interface circuit 111 can be a wired interface circuit. When the second interface circuit 111 is connected to the acquisition device 12 via wireless communication, the second interface circuit 111 can be a wireless interface circuit.

[0067] The processor 112 is electrically connected to the second interface circuit 111 and is configured to transmit the acquisition signal from the acquisition plug-in to the acquisition device 12 via the second interface circuit 111, so that the controller 123 responds to the acquisition signal, acquires biometric information, and transmits the biometric information to the processor 112 via the first interface circuit 122. In some embodiments, the processor 112 includes, but is not limited to, a single-core processor, a multi-core processor, an embedded processor, and the like.

[0068] The wireless communication module 113 is electrically connected to the processor 112 and is used to communicate with the server 20. The processor 112 controls the wireless communication module 113 to upload biometric information to the server 20. The wireless communication module 113 can be a short-range communication module such as WiFi, Bluetooth, or ZigBee, or a long-range communication module such as 4G or 5G.

[0069] Finally, it should be noted that the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification.
