Description

Technical Field

[0001] This invention relates to the field of walkie-talkie technology, specifically to a walkie-talkie fingerprint battery authentication and power-on / off control system. Background Technology

[0002] Walkie-talkies, as a convenient wireless communication device, are widely used in public safety, engineering construction, logistics and transportation, and outdoor operations. Traditional walkie-talkies typically rely solely on physical power buttons for power on / off control, lacking user identification and authentication mechanisms. Anyone with a walkie-talkie can directly turn it on and use it, which can easily lead to problems such as leakage of communication content or illegal occupation of channel resources if the device is lost or stolen. At the same time, walkie-talkie batteries, as independent power supply modules, usually only have the functions of storing and discharging electricity. Batteries between different walkie-talkies can often be interchanged, further exacerbating the risk of device abuse.

[0003] Patent CN119232192B discloses a dustproof walkie-talkie, which reduces the intrusion of dust and impurities during sound transmission.

[0004] The aforementioned patent features a dustproof structure located in front of the speaker and microphone openings. This structure effectively prevents dust, sand, and other impurities from entering the microphone and speaker, protecting sensitive electronic components and extending the device's lifespan. The opening size of the dustproof structure is adjustable. However, there is still room for improvement in terms of safe use of the walkie-talkie.

[0005] Therefore, this application proposes an authentication and power-on / off control system for a walkie-talkie fingerprint battery with authentication functionality. Summary of the Invention

[0006] The purpose of this invention is to provide an authentication and power-on control system for a walkie-talkie fingerprint battery, in order to solve the technical problem mentioned in the background art that the power-on control of traditional walkie-talkies usually relies only on a physical power button, lacks a mechanism for identifying and authenticating the user's identity, and is prone to leakage of communication content or illegal occupation of channel resources.

Heat dissipation channels are provided on both sides of the inner wall of the groove, and first sliding grooves are provided on both sides of the outer wall of the base. The first sliding grooves are used to engage with the sliders on both sides of the walkie-talkie.

The main control chip is used to receive fingerprint features transmitted by the connection line. The main control chip transmits the fingerprint features to the fingerprint comparison module through the internal bus of the circuit board. The fingerprint comparison module calls the fingerprint data in the fingerprint storage module through the data line. The fingerprint comparison module compares the called fingerprint data with the received fingerprint features and returns the comparison result to the main control chip.

S3. The main control chip transmits the comparison result to the execution module. The execution module controls the power on / off action of the walkie-talkie and grants the corresponding permissions according to the comparison result. If the comparison result is a successful match, the execution module turns on the walkie-talkie power system and grants the corresponding communication channel and system permissions according to the user's identity. If the comparison result is a failed match, the execution module prevents the walkie-talkie from turning on and prompts the authentication failure through the indicator light.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention integrates fingerprint collection and identification functions into the walkie-talkie battery by incorporating a fingerprint sensor, a housing, a circuit board, and a main control chip. This solves the technical problem of existing walkie-talkies being unable to authenticate users and lacking a fingerprint verification mechanism. The fingerprint sensor is embedded in the third slot at the bottom of the battery housing. The metal electrode plates on the surface of the fingerprint sensor directly collect the difference signals of the ridge and valley capacitance of the fingerprint as the finger is placed against it. These signals are transmitted to the main control chip on the circuit board via a connecting wire. This upgrades the walkie-talkie from a traditional unlocked device to a secure terminal with a biometric lock. Only authorized users who have registered with their fingerprints can turn on the walkie-talkie, avoiding security risks such as illegal communication and channel eavesdropping caused by lost or stolen equipment. This improves the security of walkie-talkies in sensitive fields such as public safety and military communications. 2. This invention, by incorporating a circuit board, a main control chip, and a fingerprint storage module, achieves stable storage and independent management of multiple legitimate user fingerprint templates. This solves the problems of traditional fingerprint recognition solutions, which can only record a unique administrator fingerprint and cannot support multiple users sharing a single walkie-talkie. The fingerprint storage module uses a non-volatile storage medium, which can permanently retain the registered fingerprint feature data after power failure. The main control chip transmits the fingerprint features recorded each time to the storage module through an internal bus, supporting administrators to batch record ordinary user fingerprints and add or delete users at any time. One walkie-talkie can authorize multiple legitimate users, and each user can quickly power on the device using their own finger without sharing passwords or borrowing devices from each other. This preserves the uniqueness of individual identities while meeting the needs of convenient multi-user access in team collaboration scenarios. At the same time, the administrator can independently manage the user list, improving the flexibility and maintainability of the device. 3. This invention, by incorporating a circuit board, a main control chip, and a fingerprint comparison module, achieves high-speed global comparison between collected fingerprints and stored templates. This solves the problem of not being able to accurately distinguish different user identities and avoid misidentification or rejection after storing multiple fingerprints. The fingerprint comparison module receives fingerprint features from the main control chip and performs similarity matching. Only when the similarity exceeds a preset threshold is the match considered successful. Even with a large number of user fingerprints, it can still achieve millisecond-level comparison speed with an extremely low false recognition rate. At the same time, it can accurately distinguish the identity differences between administrators and ordinary users, providing a reliable basis for subsequent differentiated access control and improving system security and user experience. 4. This invention, by incorporating a circuit board, a main control chip, and an execution module, enables automatic control of the walkie-talkie's power on / off actions and the granting of different levels of communication permissions based on comparison results. This solves the problem of not being able to perform differentiated operations and implement hierarchical permission management after identifying a specific user. The execution module receives the comparison results from the main control chip. If a match is successful, it immediately connects the walkie-talkie's power system and illuminates a green indicator light; if a match fails, it prevents power-on and illuminates a red indicator light. The execution module can automatically assign permissions based on user identity. Administrators can access all channels and system settings, while ordinary users can only use preset fixed communication channels and cannot switch to encrypted channels or administrator channels. This prevents unauthorized users from powering on the walkie-talkie and avoids unauthorized operations by legitimate users, effectively ensuring hierarchical management of the command and communication system and the orderly use of channel resources. It is particularly suitable for communication scenarios with strict permission divisions, such as security, disaster relief, and military operations. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of the present invention provides an authentication and power-on control system for a walkie-talkie fingerprint battery. The fingerprint sensor 2 is fitted with a third slot 29. The third slot 29 is located at the bottom of the outer wall of the outer shell 26. The left and right sides of the outer shell 26 are provided with first slots 27. The front side of the outer wall of the outer shell 26 is provided with a second slot 28. The top of the outer wall of the base 1 is provided with a connecting plate 3. The top of the outer wall of the connecting plate 3 is provided with a groove 5. The inner wall of the groove 5 is provided with a connecting line 6. The two sides of the inner wall of the groove 5 are provided with heat dissipation channels. The two sides of the outer wall of the base 1 are provided with first sliding grooves 7. Furthermore, the operator first aligns the outer casing 26 and the battery cell 17 with the battery slot of the walkie-talkie, ensuring that the physical interface between the battery assembly and the main body of the walkie-talkie is aligned to avoid poor circuit connection or mechanical jamming due to misalignment. Then, the operator aligns the third sliding grooves 20 on both sides of the battery cell 17 with the sliding groove in the battery slot to provide a precise guide path, allowing the battery cell 17 to slide smoothly into the battery slot and preventing the discharge port 21 from failing to connect with the walkie-talkie plug due to tilting or offset. Then, the operator pushes the outer casing 26 to push the battery cell 17 into the battery slot. At this time, the discharge port 21 at the top of the battery cell 17 is aligned with the plug inside the walkie-talkie. The operator pushes the outer casing 26 again to make the discharge port 21 of the battery cell 17 engage with the plug of the walkie-talkie, forming a stable electrical connection structure. This prevents power interruption due to vibration or collision during use and improves the reliability and stability of the system. At this time, the elastic latches on both sides of the walkie-talkie engage with the first slots 27 on both sides of the outer casing 26, completing the installation. The elastic latches and the first slots 27 are used to lock the battery assembly to prevent accidental dislodgement and facilitate subsequent disassembly. When the battery needs to be removed, simply press the elastic latches on both sides of the walkie-talkie and then pull the outer casing 26 to remove the battery cell 17, reducing the time cost for users to replace the battery. When charging is required, connect the external power cord to the charging interface of the charging board 19 for charging. The charging board 19 can convert external electrical energy into a charging voltage suitable for the battery cell 17. The current has overcurrent and overvoltage protection functions, extending battery life. The discharge protection board 22 monitors the current and voltage during battery discharge to prevent battery damage or safety accidents caused by short circuits, over-discharge or abnormal temperature, thus improving system safety. The silicone pad 24 buffers the mechanical vibration between the battery cell 17 and the outer casing 26, reducing damage to the internal structure of the battery due to impact or drop. It also has a heat dissipation function to help the battery maintain a suitable temperature range during operation. At the same time, the heat dissipation channel on the inner side of the connecting board 3 dissipates heat from the circuit board 8, thereby improving overall stability and service life.

[0024] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The present invention provides an embodiment of an identity authentication and power-on control system for a walkie-talkie fingerprint battery. A first connection hole 4 is provided at the top of the outer wall of the connecting plate 3, a communication interface 11 is provided on the side of the outer wall of the circuit board 8, the circuit board 8 is connected to the connecting line 6 through the communication interface 11, a second connection hole 10 is provided at the top of the outer wall of the circuit board 8, a connecting rod 16 is disposed in the first connection hole 4 and the second connection hole 10, and a main control chip 12, a fingerprint storage module 13, a fingerprint comparison module 14 and an execution module 15 are provided at the top of the outer wall of the circuit board 8. Furthermore, for ordinary users' fingerprints, the administrator places their fingerprint onto the metal plate of the fingerprint sensor 2. The surface of the metal plate is arrayed with multiple micro-electrodes, forming a capacitive sensing array. The fingerprint sensor 2 collects the ridge and valley structures of the fingerprint by detecting the capacitance change between the finger skin and the electrodes. When the finger is in contact with the metal plate, the ridges of the fingerprint are closer to the electrodes and have a larger capacitance value, while the valleys are farther from the electrodes and have a smaller capacitance value. The capacitance difference is converted into an electrical signal by the sensor, thereby generating a high-resolution fingerprint image, improving the accuracy and anti-interference ability of fingerprint acquisition, and adapting to the recognition needs under different environmental conditions. When the system detects that the currently recorded fingerprint is the administrator's fingerprint, the execution module 15 grants the administrator full access, including advanced functions such as fingerprint enrollment, user management, and system settings. This ensures that only authorized administrators can configure the system, preventing unauthorized users from tampering with the fingerprint database or modifying system parameters, thereby ensuring the security and manageability of the system. At this time, the indicator light on the top of the walkie-talkie is green, indicating that the user's fingerprint verification is successful, which makes it easy for the operator to confirm the system status. Then, under the guidance of the administrator, ordinary user A enters their fingerprint. The user places their fingerprint on the metal plate of the fingerprint sensor 2. The capacitive sensor detects the fingerprint feature again and collects the fingerprint feature data of ordinary user as the basis for subsequent identity authentication. The fingerprint sensor 2 transmits the collected fingerprint feature to the circuit board 8 through the connecting cable 6. The connecting cable 6 adopts a shielded twisted pair structure to reduce electromagnetic interference during signal transmission and ensure the integrity and accuracy of fingerprint data. The main control chip 12 on the circuit board 8 transmits the entered fingerprint feature to the fingerprint storage module 13 for storage through the internal bus. The administrator can enter the fingerprints of ordinary users in batches and add or delete users at any time according to permissions. The fingerprint storage module 13 adopts a non-volatile storage medium, which can retain fingerprint data even when power is off, ensuring that no re-entry is required after the system restarts, thus improving the user experience.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The present invention provides an embodiment of an authentication and power-on control system for a walkie-talkie fingerprint battery. The main control chip 12 is used to receive fingerprint features transmitted by the connection line 6. The main control chip 12 transmits the fingerprint features to the fingerprint comparison module 14 through the internal bus of the circuit board 8. The fingerprint comparison module 14 calls the fingerprint data in the fingerprint storage module 13 through the data line and compares the called fingerprint data with the received fingerprint features. The execution module 15 executes walkie-talkie actions and grants corresponding permissions according to the comparison results. A second sliding groove 9 is provided on the outer side of the circuit board 8. The circuit board 8 is connected to the first branch of the flexible circuit board 18. The flexible circuit board 18 is connected to the battery cell 17. The second branch of the flexible circuit board 18 is connected to the charging board 19. Furthermore, when ordinary user A performs fingerprint verification, ordinary user A first presses their finger onto the fingerprint sensor 2 area on the walkie-talkie battery casing 26, making the fingerprint part of the finger closely adhere to the surface of the metal electrode plate, ensuring that the ridges and valleys of the fingerprint can form a stable and clear capacitance difference distribution with the electrode plate. The metal electrode plates arrayed on the surface of the fingerprint sensor 2 start to work. When the finger skin touches the electrode plate, the fingerprint ridge is closer to the electrode plate, forming a higher capacitance value, while the fingerprint valley is farther from the electrode plate, resulting in a lower capacitance value. The capacitance difference is captured in real time by the detection circuit inside the fingerprint sensor 2 and converted into a digital fingerprint feature image. After the fingerprint sensor 2 generates fingerprint feature data, it transmits the generated fingerprint feature data to the main control chip 12 on the circuit board 8 through the connection line 6. After receiving the fingerprint feature, the main control chip 12 transmits the fingerprint feature data to the fingerprint comparison module 14 at high speed through the internal bus. After receiving the fingerprint feature, the fingerprint comparison module 14 immediately calls all the registered legal fingerprint templates in the fingerprint storage module 13. The fingerprint comparison module 14 first preprocesses the collected fingerprint image, including median filtering for noise reduction and image enhancement, to eliminate image noise caused by fingerprint stains, minor scratches or changes in ambient light, and to highlight the clarity of the fingerprint ridge. Then, the fingerprint comparison module 14 extracts the fingerprint's detailed feature points, including endpoints, bifurcation points, island structures and core points, to form a unique high-dimensional feature vector. Finally, the generated feature vector is matched with each template in the fingerprint storage module 13 for similarity. When the similarity exceeds the preset threshold (e.g., 85%), it is determined to be a successful match. Under the premise of ensuring an extremely low false recognition rate, it realizes fast and accurate verification of the identity of ordinary users. The fingerprint comparison module 14 returns the comparison result as "matching ordinary user A" to the main control chip 12 via the internal data bus, providing the main control chip 12 with a clear identity recognition result as the basis for subsequent actions. After receiving the comparison result, the main control chip 12 transmits the comparison result to the execution module 15. The execution module 15 detects that the comparison result is "matching ordinary user A" and immediately performs the walkie-talkie power-on action, putting the device into working state. At the same time, the main control chip 12 controls the indicator light on the top of the walkie-talkie to light up green, indicating that the user authentication is successful and the power-on is completed, enhancing the user-friendliness and convenience of human-computer interaction. At this time, the execution module 15 automatically opens the preset fixed communication channel according to the permission policy pre-set for "ordinary user A" in the system, while prohibiting ordinary user A from accessing the administrator channel or other encrypted channels, preventing ordinary user from unintentionally or intentionally entering unauthorized communication areas, ensuring the hierarchical management and security of the communication command system, and avoiding the abuse of channel resources, thus improving the user's convenience and the system's security protection capabilities.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The present invention provides an embodiment of an authentication and power-on control system for a walkie-talkie fingerprint battery. A main control chip 12, a fingerprint storage module 13, a fingerprint comparison module 14, and an execution module 15 are disposed on the top of the outer wall of a circuit board 8. Third sliding grooves 20 are disposed on both sides of the outer wall of a battery cell 17. A discharge port 21 is disposed on the top of the outer wall of the battery cell 17, and the discharge port 21 is connected to the walkie-talkie plug. The top of the outer wall of the battery cell 17 is connected to a discharge protection board 22. A first rectangular groove 23 is disposed on the top of the outer wall of the discharge protection board 22. The top of the outer wall of the discharge protection board 22 is connected to a silicone pad 24. A second rectangular groove 25 is disposed on the top of the outer wall of the silicone pad 24. Furthermore, when an administrator performs fingerprint verification, the administrator places their fingerprint into the sensing area of ​​the fingerprint sensor 2. At this time, the fingerprint is in contact with the metal plate. The capacitance array on the surface of the metal plate quickly detects the capacitance changes caused by the fingerprint ridges and valleys. The fingerprint ridges are closer to the plate, resulting in a higher capacitance value, while the valleys result in a lower capacitance value. The capacitance difference is converted into a digital signal, forming a high-resolution fingerprint image. The fingerprint sensor 2 transmits the collected fingerprint features to the main control chip 12 via the connection line 6. After receiving the fingerprint features, the main control chip 12 transmits the fingerprint features to the fingerprint comparison device via the internal bus. In module 14, the fingerprint comparison module 14 calls the fingerprint template stored in the fingerprint storage module 13 for comparison. The fingerprint comparison module 14 finds that it "matches the administrator" and returns the result to the main control chip 12. The main control chip 12 transmits the comparison result to the execution module 15. The execution module 15 turns on the power system of the walkie-talkie and opens all channels. The administrator can use all preset channels and extended channels, enabling the administrator to switch communication frequency bands in emergencies, coordinate multiple communication tasks, improve the flexibility and efficiency of command and dispatch, and enhance the manageability and security of the system.

[0027] Please see Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 The present invention provides an embodiment of an authentication and power-on control system for a walkie-talkie fingerprint battery. The fingerprint sensor 2 and the third card slot 29 are interlocked. The surface of the fingerprint sensor 2 is arrayed with metal electrode plates, which are used to fit against the skin of the finger. The outer shell 26 is provided with first card slots 27 on the left and right sides, which are used to engage with the card block of the walkie-talkie. Furthermore, when the walkie-talkie is lost, unfamiliar users cannot authenticate via fingerprint. When a stranger finds the walkie-talkie, they may abandon its use because they are unaware of fingerprint verification. However, when a stranger tries to use it, the fingerprint adheres to the metal plate of the fingerprint sensor 2. The capacitance array on the surface of the metal plate detects the ridge and valley distribution of the unfamiliar fingerprint. The fingerprint sensor 2 generates a fingerprint image based on the capacitance difference. Even if the stranger is not authorized, the system can still collect their fingerprint data normally as a basis for identity verification. The fingerprint sensor 2 transmits the collected fingerprint features to the main control chip 12 via the connection line 6. After receiving the fingerprint features, the main control chip 12 transmits them to the fingerprint comparison module 14 via the internal bus. The fingerprint comparison module 14 calls all registered legal fingerprint features in the fingerprint storage module 13 and performs a one-to-many global comparison. Since there are no fingerprint features of strangers in the fingerprint storage module 13, the system does not find any matching items with similarity exceeding the threshold after traversing all templates. At this time, the fingerprint comparison module 14's comparison result is "not matched", clearly indicating that the current user is an unauthorized person, providing a basis for judgment for subsequent actions. The fingerprint comparison module 14 returns the comparison result to the main control chip 12. The main control chip 12 controls the indicator light on the top of the walkie-talkie to turn red according to the preset security policy, indicating that the fingerprint verification failed and the current device is in an unauthorized access state. At the same time, the main control chip 12 also sends an instruction to the execution module 15 to prevent the walkie-talkie's power system from being turned on, improving the walkie-talkie's security protection capability in the event of loss or theft and reducing the risk of the device being used illegally.

[0028] Working principle: After the user installs the walkie-talkie battery pack into the walkie-talkie body, the system is in an authentication state. When the user's finger touches the metal electrode plate on the surface of the fingerprint sensor 2, the electrode array generates a high-resolution fingerprint image signal by detecting the capacitance difference between the fingerprint ridges and valleys. The signal is transmitted to the main control chip 12 on the circuit board 8 through the connection line 6. The main control chip 12 sends the fingerprint feature data to the fingerprint comparison module 14 through the internal bus. The fingerprint comparison module 14 calls the registered legitimate fingerprint templates in the fingerprint storage module 13 to perform similarity matching. If the match is successful and the similarity exceeds the preset threshold, the comparison result is returned to the main control chip 12. The main control chip 12 then drives the execution module 15 to turn on the walkie-talkie power system and opens the corresponding communication channel and system permissions according to the user's identity (administrator or ordinary user). If the match fails, the execution module 15 will prevent the power-on and indicate that the authentication has failed through an indicator light (such as a red light). The entire identity authentication and power-on / off control process is automatically completed the moment the user presses their fingerprint, realizing walkie-talkie security management based on fingerprint recognition.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
