[0020] The present invention is further explained below in conjunction with the drawings and specific embodiments of the specification. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0021] Combined with Figure 1 As shown, the present invention provides a PTT fast authentication system based on fingerprint recognition, including: a PTT button module with fingerprint recognition, based on the traditional PTT button, a fingerprint recognition module is embedded in the center, the entire PTT button module has a control module interface, the fingerprint recognition module is used to identify the user's fingerprint information, and transmit the identified fingerprint signal to the control module, and the PTT button is used to identify the call request sent by the user to the control module. The fast PTT authentication of fingerprint recognition requires that the PTT button module with fingerprint recognition is connected to the control module of the intercom, and the fingerprint recognition can be performed by touching the PTT button after the user turns on the machine, thereby authenticating the user's identity. Based on different users, different user identities and permissions are switched instantly during communication. When the user's fingerprint authentication fails, the user's call request is automatically rejected. The specific implementation consists of hardware and software, wherein the hardware includes a PTT button module with a fingerprint recognition module and a corresponding interface, and the software needs to be adapted in the intercom or other communication equipment used specifically. The PTT fast authentication system of the present invention can be applied to products such as intercoms, hand microphones or Bluetooth headsets. More specifically, the fingerprint recognition module adopts a touch-type capacitive fingerprint recognition module, which is embedded in the center of the PTT button and then connected to the entire intercom system.

[0022] According to an embodiment of the present invention, a PTT quick authentication method based on fingerprint recognition of the present invention, by pressing the fingerprint recognition area on the PTT button module, the fingerprint recognition module transmits the recognized user identity data to the control module, and then compares it with the user sample preset in the control module to determine the authenticity of the user identity, and then responds. If the user identity is true after comparison, the system will directly initiate a call or group call with the corresponding authority according to the user authority preset in the control module; if the user identity is distorted after comparison, the call will be rejected and the answering of this application product will be restricted until the next user identity is recognized to be true, and this application product resumes normal function. For different users, calls with different permissions can be made through the same application product, and the system will automatically switch to the authority level that matches their user identity according to the recognized true identity of the user. For different user talk groups, identity information can be bound to the same application product to make calls with different permissions, and the system will automatically switch to the corresponding user talk group according to the different user identities recognized.

[0023] According to an embodiment of the present invention, whether the user identity is authentic refers to whether the user identity information is preset in the user sample library. If it is authentic, the user identity information is preset in the user sample library; if it is not authentic, the user identity information is not preset in the user sample library.

[0024] Embodiment 1

[0025] Combined with Figure 2 As shown, a PTT button module with fingerprint recognition is applied to an intercom, and the intercom includes: an intercom system and a PTT button module, the control module in the intercom system is connected to the PTT button module, and the intercom system also includes: an audio module, a password module, a keyboard module, a display module, a radio frequency module, a positioning module and an antenna, the audio module, the password module, the keyboard unit, the display module, the radio frequency module and the positioning module are respectively connected to the control module, and the radio frequency module is also connected to the antenna.

[0026] According to an embodiment of the present invention, after the walkie-talkie is turned on, by touching the fingerprint recognition area on the PTT, the fingerprint recognition module transmits the recognized identity data to the control module on the walkie-talkie, and the control module performs user identity authentication by matching the built-in user fingerprint library. If the user identity recognition does not match the built-in fingerprint library, the walkie-talkie will not enter the normal receiving state until a legal or authentic user identity is matched. After the identity authentication is passed, the control module sets the call ID and the corresponding user authority based on the matched user identity. At this time, the walkie-talkie is in a normal receiving state. Through the RF antenna, the walkie-talkie receives the useful signal in the space and transmits it to the RF module. The RF module processes and demodulates the received signal and transmits the demodulated baseband signal to the control module. After the control module processes the baseband signal, it performs corresponding processing according to the content of the signal. If the signal is receivable by the walkie-talkie user who meets the authority, the signal is decrypted through the password module. If the decrypted signal is a call signal, the control module transmits the signal to the audio module. After the audio module performs digital-to-analog conversion, it plays the sound through the speaker. At the same time, the control module displays the corresponding call status through the display module. If the decrypted signal is a text message signal, the control module directly stores the text message data in the text message mailbox and sends a text message prompt tone through the audio module. After the user operates the keyboard unit to check, the control module displays the text message information through the display unit. In this way, the user can receive calls and text messages initiated by other users or the dispatch desk. When transmitting, when the user presses the PTT button, the fingerprint recognition area will be touched, and the intercom will perform identity authentication again. After the identity authentication is passed, the control module enables the audio module to turn on the microphone, and the user's voice is transmitted to the processing module of the audio module through the microphone. After audio sampling, the analog audio is converted into a digital signal and the signal is transmitted to the control module. After the control module encrypts the audio signal through the password module, it performs call encoding according to the user's identity information. The encoded baseband signal will be transmitted to the RF module. After the RF module modulates and amplifies the baseband signal, it is sent to the antenna. The antenna radiates the signal into space, and the transmission is completed.

[0027] When sending, the intercom can instantly adjust different permissions according to the latest user identity recognition status, so that when the traffic of a single user is not high, multiple users can use the same intercom at the same time, and different IDs and user permissions can be automatically switched. Even identities can be bound to different user talk groups. When users with different identities make calls, different talk groups are automatically switched, which simplifies user operations and improves communication efficiency. At the same time, the control module can provide user identity recognition prompts on the intercom display interface at any time according to the user recognition status.

[0029] Combined with Figure 3As shown, a PTT button module with fingerprint recognition is applied to a hand microphone, and the hand microphone includes: a hand microphone system and a PTT button module, and the hand microphone system and the PTT button module are respectively connected to the control module interface, and the hand microphone system also includes: a keyboard module, a display module, a microphone (MIC) and a speaker (SPEAKER), and the keyboard module, the display module, the microphone and the speaker are respectively connected to the control module interface.

[0030] In actual use, it needs to be matched with a corresponding vehicle-mounted station or other cluster communication equipment that can be equipped with a microphone to realize its functions, and is connected to the vehicle-mounted station or other cluster communication equipment through a control module interface. The specific function flow is the same as the walkie-talkie use process of the first embodiment.

[0031] The present invention is realized by combining software and hardware. The hardware part can be realized by using a PTT button module with fingerprint recognition, which is connected to an intercom control module through an interface. The software part is executed by the control module, and a fingerprint recognition process is added to the traditional intercom communication process.
