Description

Technical Field

[0001] This invention relates to the field of electronic signal transmission technology, and in particular to an electronic signal transmission system with anti-interception function. Background Technology

[0002] Electronic signals are carriers of information transmitted, processed, and stored using electronic methods. They are divided into analog signals and digital signals. Analog signals use combinations of voltage amplitude and frequency to express information, while digital signals represent information using discrete numerical values. The five elements of electronic signals include DC, AC, frequency modulation, pulse width modulation, and serial data signals. These elements are widely used in fields such as automobiles and communications. During electronic signal transmission, physical interception devices can block electronic signals, affecting the stability of electronic signal transmission.

[0003] Existing technologies include methods to reach the location of communication transmission terminals by enhancing the frequency of electronic signals or by bypassing signal shielding areas through other nodes. However, the establishment of signal relays requires a long waiting time, and the signal transmission delay, energy consumption, and accuracy in the extended channel area do not meet the channel design requirements, leaving room for improvement. Summary of the Invention

[0004] This invention provides an electronic signal transmission system with anti-interception function, which is used to establish a fast electronic signal transmission channel while taking into account both anti-interception function and cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, an electronic signal transmission system with anti-interception function is provided. The method is applied to a communication terminal. The system is applied to the communication terminal, which includes: acquiring the signal strength (RSSI) values ​​and data packet transmission delay (τ) of M relay nodes, where M is an integer greater than 2; when the RSSI value is less than a threshold or τ is greater than a threshold, it is determined to be a weakened connection state, and a first communication power adjustment mode is initiated; when RSSI is greater than or equal to a threshold and τ is less than or equal to a threshold, it is determined to be a stable connection state, and a second communication power adjustment mode is initiated; when a stable connection cannot be established after the first communication power adjustment, a third communication power adjustment mode is initiated and a data network link reselection mechanism is triggered.

[0006] Optionally, the topology information of the M smart fuses indicates that the first communication power adjustment mode includes: Increase the transmission power to transmit a bandwidth detection signal; The presence of interference is determined by the spectral distortion rate β of the received signal: if β is greater than the preset delay threshold, active interception is confirmed.

[0007] Optionally, the second communication power adjustment mode includes: Construct the power optimization function:

[0008] Where δ is the safety margin, and the optimal power vector [P_1, P_2, ..., P_n] is solved by the Lagrange multiplier method.

[0009] Optionally, the third communication power adjustment mode includes: A judgment mechanism is activated. When multipath fading is detected, the space-time coding compression bandwidth is activated to improve the power spectral density. When the interception is determined to be active, frequency hopping spread spectrum (FHSS) technology is used to transmit chirp modulated signals in the 2.4GHz / 5.8GHz dual-band, expanding the signal bandwidth by 3 times to enhance penetration.

[0010] Optionally, the link reselection mechanism of the communication terminal includes: Establish concentric circle regions {} with increasing radius centered on the current communication terminal; Select the relay node with the highest signal-to-noise ratio (SNR) within the annular region C_k; If there is a shielded region in memory C_k, then construct a circumcircle topological path, and the path satisfies: Path loss: ; And node j ∉ the set of shielded regions S.

[0011] Optionally, selecting the relay node with the highest signal-to-noise ratio (SNR) within the annular region C_k specifically includes: the signal strength and data packet transmission delay indicating the signal relay topology of the M relay nodes, and the communication terminal selecting N relay nodes with key connection positions from the M relay nodes based on the signal relay topology of the M relay nodes.

[0012] Optionally, the communication terminal selects N relay nodes with key connection positions from the M relay nodes according to the signal relay topology of the M relay nodes, including: the shortest signal relay topology around the set of shielded areas S in the circumcircle topology path of the N discretely distributed relay nodes.

[0013] Optionally, the communication terminal selects N relay nodes with key connection positions from the M relay nodes according to the signal relay topology of the M relay nodes, including determining whether at least two branches of at least two nodes meet the quality score within the concentric circle range. If they do, the concentric circle scanning branch selection of the next branch continues until the transmission target node is selected. It also includes expanding the incremental concentric circle scan range when a node does not meet the quality score, and continuing to complete the signal relay topology after confirming that at least one branch of at least two other nodes that meet the quality score has been identified.

[0014] Optionally, it includes an electronic signal transmission device with anti-interception function, comprising: The signal acquisition module is used to acquire the signal strength and data packet transmission delay of the signal transmission relay node; A communication power adjustment module is used to adjust the communication power according to the current communication status; The communication power optimization calculation module is used to calculate the optimal electronic signal transmission power under steady-state conditions. The relay topology module is used to establish a signal topology based on the signal quality of the central node.

[0015] In a second aspect, an electronic device is provided, comprising: a processor and a memory; the memory is used to store a computer program, which, when executed by the processor, causes the electronic device to perform the method described in the first aspect.

[0016] In one possible design, the electronic device described in the third aspect may further include a transceiver. This transceiver may be a transceiver circuit or an interface circuit. The transceiver can be used for communication between the electronic device described in the third aspect and other electronic devices.

[0017] In the embodiments of the present invention, the electronic device described in the third aspect may be a terminal, or a chip (system) or other component or assembly disposed in the terminal, or a system containing the terminal.

[0018] Thirdly, a computer-readable storage medium is provided, comprising: a computer program or instructions; when the computer program or instructions are executed on a computer, the computer causes the computer to perform the method described in the first aspect.

[0019] In summary, the above methods and systems have the following technical effects: In this invention, the communication power adjustment mode can be changed according to the signal strength and data packet delay of the relay node. This is beneficial for achieving low-power operation in a stable state, as well as adaptive control in a weakened connection state and a signal loss state. It meets the needs of electronic signal transmission in the presence of anti-interception measures. Furthermore, by setting concentric circles, the relay node with the highest signal-to-noise ratio can be quickly scanned and established. And by using the topological path of the outer circle of the component, electronic signal transmission around the shielded interception area can be achieved. Attached Figure Description

Alternatively, the terminal device may also be a customer-premises equipment (CPE).

[0032] A relay node can be a signal repeater or a signal relay gateway that is connected to a communication terminal.

[0033] Figure 1 This is a flowchart illustrating the method provided in an embodiment of the present invention. This electronic signal transmission system with anti-interception function can be applied to the aforementioned communication terminal. The specific process is as follows: The communication terminal acquires the RSSI values ​​of the signal strength of M relay nodes and the data packet transmission delay τ, where M is an integer greater than 2; When the RSSI value is less than the threshold or τ is greater than the threshold, it is determined to be a weakened connection state, and the first communication power adjustment mode is activated. When RSSI≥ and τ≤, the connection is determined to be stable and the second communication power adjustment mode is started. If a stable connection cannot be established after the first communication power adjustment, the third communication power adjustment mode is activated and the data network link reselection mechanism is triggered.

[0034] Scenario 1: The topology information of the M smart fuses indicates that the first communication power adjustment mode includes: Increase the transmission power to transmit a bandwidth detection signal; The presence of interference is determined by the spectral distortion rate β of the received signal: if β is greater than the preset delay threshold, active interception is confirmed.

[0035] Based on this, the second communication power adjustment mode includes: Construct the power optimization function:

[0036] Where δ is the safety margin, and the optimal power vector [P_1, P_2, ..., P_n] is solved by the Lagrange multiplier method.

[0037] Furthermore, the third communication power adjustment mode includes: A judgment mechanism is activated. When multipath fading is detected, the space-time coding compression bandwidth is activated to improve the power spectral density. When the interception is determined to be active, frequency hopping spread spectrum (FHSS) technology is used to transmit chirp modulated signals in the 2.4GHz / 5.8GHz dual-band, expanding the signal bandwidth by 3 times to enhance penetration.

[0038] Optionally, the link reselection mechanism of the communication terminal includes: Establish concentric circle regions {} with increasing radius centered on the current communication terminal; Select the relay node with the highest signal-to-noise ratio (SNR) within the annular region C_k; If there is a shielded region in memory C_k, then construct a circumcircle topological path, and the path satisfies: Path loss:

[0039] Where node j ∉ the set of shielded regions S.

[0040] Scenario 2: The selection of the relay node with the highest signal-to-noise ratio (SNR) within the annular region C_k specifically includes: the signal strength and data packet transmission delay indicating the signal relay topology of M relay nodes, and the communication terminal selecting N relay nodes with key connection positions from the M relay nodes based on the signal relay topology of the M relay nodes.

[0041] The communication terminal selects N relay nodes with key connection positions from the M relay nodes based on the signal relay topology of the M relay nodes, including: the shortest signal relay topology around the set of shielded areas S in the circumcircle topology path of the N discretely distributed relay nodes.

[0042] In one example, the communication terminal selects N relay nodes with key connection positions from the M relay nodes based on the signal relay topology of the M relay nodes. This includes determining whether at least two branches of at least two nodes meet the quality score within the concentric circle range. If they do, the terminal continues to select the next branch in the concentric circle scanning until the target node for transmission is selected. It also includes increasing the incremental concentric circle scan range when a node does not meet the quality score, and continuing to complete the signal relay topology after confirming that at least one branch of at least two other nodes that meet the quality score has been identified.

[0043] It also includes electronic signal transmission devices with anti-interception capabilities, including: The signal acquisition module is used to acquire the signal strength and data packet transmission delay of the signal transmission relay node; A communication power adjustment module is used to adjust the communication power according to the current communication status; The communication power optimization calculation module is used to calculate the optimal electronic signal transmission power under steady-state conditions. The relay topology module is used to establish a signal topology based on the signal quality of the central node.
