Description

Technical Field

[0001] This invention relates to a novel integrated communication vehicle system, belonging to the field of tactical communication. Background Technology

[0002] Traditional communication vehicles employ a distributed equipment layout and independent wiring mode, which has significant technical drawbacks:

[0003] 1. Cable Redundancy Issue: Taking a certain type of communication vehicle as an example, it needs to integrate 12 types of communication equipment (including switches, servers, encryption machines, etc.). Each device is independently powered and connected point-to-point, resulting in more than 313 cables in the entire vehicle (including 130 power cables and 183 signal cables), with a total weight of 28 kg and occupying 0.2 m of space. 3 .

[0004] 2. Difficulty in system expansion: Adding new equipment requires redesigning the cabling path, and the typical expansion cycle takes more than 72 hours. In addition, the intertwined cables cause electromagnetic interference (tests show that crosstalk between adjacent cables reaches -28dB).

[0005] 3. Low maintenance efficiency: Fault location requires manual inspection segment by segment. Statistical data shows that the average time to repair a fault (MTTR) is as long as 4.5 hours, of which 68% of the time is spent on cable inspection.

[0006] 4. Poor clock synchronization accuracy: Each device uses an independent clock source, and the time deviation of the entire network exceeds ±500μs, which seriously affects the quality of collaborative communication. Summary of the Invention

[0007] To address the aforementioned problems, this invention discloses a novel communication vehicle integration system, which achieves a revolutionary approach to communication vehicle integration through two-level reconstruction at the physical and protocol layers:

[0008] A novel communication vehicle integrated system includes: a modular equipment carrier platform, which is composed of a 6061-T6 aluminum alloy frame and has a three-layer structure comprising an upper equipment installation area, a middle platform bus area, and a lower cooling fan area;

[0009] The upper-level equipment installation area integrates standardized equipment interfaces, including a shock-resistant locking mechanism and a 48-pin military connector, enabling blind-plug installation of modular equipment.

[0010] The five types of buses integrated within the middle-layer platform bus area are:

[0011] a) Switching bus: The modular device platform integrates switching modules and a switching bus; the switching modules construct a star topology network through the switching bus to send and receive services and support VLAN isolation;

[0012] b) Management Bus: The modular device platform integrates a management module and a management bus; the management module interacts with the management agent module of the modular device through the management bus, based on the device management protocol and device management messages, to achieve device health monitoring;

[0013] c) Clock bus: The modular device carrier platform integrates a clock module and a clock bus. The clock module interacts with the clock agent module of the modular device through the clock bus, based on the device clock protocol and device clock messages, to achieve nanosecond-level synchronization.

[0014] d) Cryptographic bus: The modular device carrier platform integrates a cryptographic module and a cryptographic bus. The cryptographic module interacts with the cryptographic proxy module of the modular device through the cryptographic bus, based on the device cryptographic protocol and device cryptographic messages. It supports SM2 / SM4 / SM9 encryption algorithms.

[0015] e) Power bus: The modular device carrier platform integrates power modules and power buses. The power modules interact with the power agent modules of the modular devices through the power bus, based on the device power protocol and device power messages, to support dynamic power distribution.

[0016] The lower cooling fan area integrates cooling fans and heat dissipation channels to achieve heat dissipation for modular equipment.

[0017] Furthermore,

[0018] The device management protocol interaction process is as follows:

[0019] Step 101: After the modular device is powered on, the management agent module sends a discovery message to the management module via broadcast, reporting that the modular device has been powered on and its status information after power-on, including temperature (T), voltage (V), vibration (G), CPU load (L), memory utilization (M), and packet loss rate (P).

[0020] Step 102: After receiving the discovery message from the modular device, the management module sends a polling message to the management module every 30 seconds by default to query the status information of the modular device.

[0021] Step 103: After receiving the polling message from the management module, the management agent module replies with a status report message, reporting the status information of the modular device, including temperature (T), voltage (V), vibration (G), CPU load (L), memory utilization (M), and packet loss rate (P).

[0022] Step 104: Based on the status information received from the management module, the management module dynamically constructs a modular device health model. The modular device health calculation formula is as follows:

[0023] Y = a * X T+b*X V +c*X G +d*X L +e*X M +f*X P

[0024] Among them, X T X V X G X L X M X P These are the changes in temperature (T), voltage (V), vibration (G), CPU load (L), memory utilization (M), and packet loss rate (P) for the most recent two times, respectively, with a, b, c, d, e, and f being the corresponding weighting coefficients.

[0025] Step 105: The management module dynamically adjusts the polling interval based on the modular device health status. The polling interval is set as follows:

[0026]

[0027]

[0028] Step 106: The management module uses an LSTM model to predict the probability of failure (0-100%) of the modular device in the next 24 hours based on the received modular device temperature (T), voltage (V), vibration (G), CPU load (L), memory utilization (M), and packet loss rate (P).

[0029] Step 107: If the predicted probability of modular equipment failure is ≥80%, an alarm will be sent to the user to remind them to conduct an inspection or replace the equipment as soon as possible.

[0030] Device management messages are carried on Ethernet packets, with the Ethernet packet type field being 0x88D2. Device management messages include: discovery messages, polling messages, and status report messages.

[0031] Furthermore,

[0032] The device clock protocol interaction includes:

[0033] Step 201, the clock module periodically (synchronization interval T) new =2 seconds, basic period) to send a device clock message carrying timestamp t1;

[0034] Step 202: The clock proxy module records the message arrival time t2;

[0035] Step 203: After a random delay (between 0 and 1 millisecond), the clock agent sends a device clock message carrying timestamp t3.

[0036] Step 204: The clock module returns a device clock message carrying timestamp t4.

[0037] Step 205: The clock proxy module records the message arrival time t4, calculates the clock deviation OS_raw=(t2-t1-t4+t3) / 2, calculates the path delay DL=(t2-t1+t4-t3) / 2, and calculates the network jitter Jitter=|(t2-t1)-(t4-t3)|;

[0038] Step 206: Calculate the optimal synchronization interval T in real time based on network jitter and clock skew (OS). new =T base *(1+α*|OS_raw|+β*Jitter), and adjust the subsequent clock synchronization interval.

[0039] Wherein: T base = 2 seconds (base cycle), α = 0.1 (deviation weighting coefficient), β = 0.05 (jitter weighting coefficient)

[0040] Step 207: Calculate the temperature drift compensation amount T_T = k1*(T_current - T_cal) + k2*(T_current - T_cal) 2

[0041] Wherein, T_current is the ambient temperature value of the device acquired in real time by a temperature sensor, and T_cal is the reference temperature calibrated under standard laboratory conditions (e.g., 25℃), used to calculate the temperature deviation. k1 is the first-order temperature compensation coefficient (unit: ns / ℃), used to describe the linear effect of temperature changes on clock deviation, set to k1 = 0.05ns / ℃ (meaning that for every 1℃ increase, the clock deviation increases linearly by 0.05ns). k2 is the second-order temperature compensation coefficient (unit: ns / ℃²), used to describe the nonlinear effect of temperature changes (e.g., the frequency-temperature curve of a crystal oscillator exhibits parabolic characteristics), set to k2 = 0.001ns / ℃² (meaning that for every 1℃ deviation of the temperature from T_cal, the nonlinear deviation increases by 0.001ns).

[0042] Step 208: Calculate the phase noise compensation caused by the vibration of the communication vehicle. The calculation formula is as follows:

[0043] T_V=∫(a(t)*K)dt

[0044] (a(t) is the real-time vibration acceleration collected by an accelerometer (such as a MEMS triaxial accelerometer), and K is the vibration-time deviation conversion coefficient (unit: ns / g), which is used to describe the cumulative effect of unit vibration acceleration on clock deviation. The default K = 0.1 ns / g)

[0045] Step 209: Correct the local clock to achieve time synchronization with the clock module, ensuring dynamic adaptation to the network environment and maintaining clock synchronization accuracy. The calculation formula is as follows:

[0046] OS_corrected=OS_raw-(T_T+T_V)

[0047] Where OS_raw is the calculated uncorrected clock skew (in ns), and OS_corrected is the corrected clock skew (in ns).

[0048] The device clock message is carried on an Ethernet packet, and the Ethernet packet type field is 0x88D3.

[0049] Furthermore,

[0050] The specific device cryptographic protocol interaction process is as follows:

[0051] Step 301: The cryptographic module integrates a quantum random number generator (QRNG) to collect photon polarization states in real time and generate a quantum entropy source QRNG_output. Simultaneously, it combines a chaotic mapping (Logisticμ = 3.999) to generate a chaotic sequence Chaos_sequence, which is then XORed with the quantum entropy source to generate the session key Sec. The calculation formula is as follows:

[0052] Sec=QRNG_output⊕Chaos_sequence

[0053] Step 302: When the modular device is connected, the cryptographic proxy module is used to collect hardware fingerprints (SHA3-256 (FPGA bit stream), acoustic features (MFCC coefficients + Gaussian mixture model) and dynamic power consumption signatures (power consumption trace of running specific instructions), and send authentication and encryption request messages to the cryptographic module.

[0054] Step 303: Upon receiving the data, the cryptographic module verifies it. If verification fails, it refuses to send the session key, determines that an attack may exist, and sends a power-off command to the corresponding modular device to the power module; if verification succeeds, it sends the session key to the cryptographic proxy module.

[0055] Step 304: The password proxy module calls the encryption algorithm, encrypts the data using the session key, and sends it to the receiving end.

[0056] Furthermore,

[0057] The device power protocol interaction process includes:

[0058] Step 401: After the modular device is powered on, the power proxy module sends a registration request message to the power module, carrying the device hardware fingerprint (SHA3-256), rated power (16-bit), security certificate (SM2 signature), and dynamic power consumption feature code information. This requests the power allocation required by the modular device.

[0059] Step 402: Upon receiving the power module, the certificate validity is verified, and the power consumption feature code is compared with the database to prevent cloned devices from accessing the system. If verification fails, power supply to the modular device is refused; if verification passes, power is dynamically allocated according to the power requirements of the modular device.

[0060] Step 403: The power module uses an LSTM neural network model, inputting historical power sequences (sampled every 1 second), device type, and task queue depth, to predict the modular device power consumption Ppred for the next 30 seconds, and dynamically pre-allocates power. This transforms traditional reactive power allocation into predictive power allocation, shortening the power supply response time for sudden load increases and avoiding instantaneous overload.

[0061] Step 404: The power proxy module monitors the device-side voltage in real time. If it finds that the voltage change does not meet the usage requirements of the modular device, it sends feedback to the power module in real time, and the power module makes dynamic adjustments.

[0062] Step 405: The power module receives the power-off command sent by the password module and directly cuts off the power to the corresponding modular device.

[0063] Step 406: When the power module detects a current greater than 110% of the rated value, it sends an overload power-off message to the power agent module of the modular device and cuts off the power supply.

[0064] Compared with the prior art, the present invention has the following advantages:

[0065] This invention proposes a communication vehicle integration method that addresses the problem of excessive cable count in traditional distributed cabling methods. It proposes a modular equipment carrier platform where communication equipment is modularly designed and deployed. Interconnect cables between devices are integrated into the modular equipment carrier platform for connecting the modular devices deployed on it. The modular equipment carrier platform employs a bus-based cabling system, primarily composed of five types of buses: switching, management, clock, cryptography, and power. This provides five types of connections for the modular devices integrated on the platform: information exchange, health management, clock information, cryptography management, and power management. This significantly reduces the number of cables required for integration in the communication vehicle. Attached Figure Description

A 48-pin military-grade connector is mounted on the back, interconnecting with the modular device's platform and interacting via corresponding buses and protocols.

[0084] like Figure 1 As shown, this invention designs a novel integrated communication vehicle system. By designing a modular equipment carrier platform, communication equipment is modularly designed and deployed on the platform. Interconnecting cables between devices are built into the modular equipment carrier platform for connecting the modular devices deployed on it. The modular equipment carrier platform adopts a bus-type cabling method, mainly composed of five types of buses: switching, management, clock, cryptography, and power. It can integrate the modular devices mounted on the platform, providing five types of connections: information exchange, health management, clock information, cryptography management, and power management.

[0085] 1. Construction of Modular Equipment Support Platform

[0093] The physical layer uses CAT7 shielded twisted pair cable (AWG24 gauge), and each device is allocated one 10 Gigabit port (10GBase-T).

[0094] 3. Management bus implementation:

[0095] The management module is deployed on an ARM Cortex-A53 processor (1.2GHz).

[0096] (1) The device management protocol interaction includes:

[0097] Step 101: After the modular device is powered on, the management agent module sends a discovery message to the management module via broadcast, reporting that the modular device has been powered on and its status information after power-on, including temperature (T), voltage (V), vibration (G), CPU load (L), memory utilization (M), and packet loss rate (P).

[0098] Step 102: After receiving the discovery message from the modular device, the management module sends a polling message to the management module every 30 seconds by default to query the status information of the modular device.

[0099] Step 103: After receiving the polling message from the management module, the management agent module replies with a status report message, reporting the status information of the modular device, including temperature (T), voltage (V), vibration (G), CPU load (L), memory utilization (M), and packet loss rate (P).

[0100] Step 104: Based on the status information received from the management module, the management module dynamically constructs a modular device health model. The modular device health calculation formula is as follows:

[0101] Y = a * X T +b*X V +c*X G +d*X L +e*X M +f*X P

[0102] Among them, X T X V X G X L X M X PThese are the changes in temperature (T), voltage (V), vibration (G), CPU load (L), memory utilization (M), and packet loss rate (P) for the most recent two times, respectively, with a, b, c, d, e, and f being the corresponding weighting coefficients.

[0103] Step 105: The management module dynamically adjusts the polling interval based on the modular device health status. The polling interval is set as follows:

[0104] Health Polling interval ≥80 300 seconds 60-79 120 seconds <60 30 seconds

[0105] Step 106: The management module uses an LSTM model to predict the probability of failure (0-100%) of the modular device in the next 24 hours based on the received modular device temperature (T), voltage (V), vibration (G), CPU load (L), memory utilization (M), and packet loss rate (P).

[0106] Step 107: If the predicted probability of modular equipment failure is ≥80%, an alarm will be sent to the user to remind them to conduct an inspection or replace the equipment as soon as possible.

[0116] Step 201, the clock module periodically (synchronization interval T) new =2 seconds, basic period) to send a device clock message carrying timestamp t1;

[0117] Step 202: The clock proxy module records the message arrival time t2;

[0118] Step 203: After a random delay (between 0 and 1 millisecond), the clock agent sends a device clock message carrying timestamp t3.

[0119] Step 204: The clock module returns a device clock message carrying timestamp t4.

[0120] Step 205: The clock proxy module records the message arrival time t4, calculates the clock deviation OS_raw=(t2-t1-t4+t3) / 2, calculates the path delay DL=(t2-t1+t4-t3) / 2, and calculates the network jitter Jitter=|(t2-t1)-(t4-t3)|;

[0121] Step 206: Calculate the optimal synchronization interval T in real time based on network jitter and clock skew (OS). new =T base *(1+α*|OS_raw|+β*Jitter), and adjust the subsequent clock synchronization interval.

[0122] Wherein: T base = 2 seconds (base cycle), α = 0.1 (deviation weighting coefficient), β = 0.05 (jitter weighting coefficient)

[0123] Step 207: Calculate the temperature drift compensation amount T_T = k1*(T_current - T_cal) + k2*(T_current - T_cal) 2

[0124] Wherein, T_current is the ambient temperature value of the device acquired in real time by a temperature sensor, and T_cal is the reference temperature calibrated under standard laboratory conditions (e.g., 25℃), used to calculate the temperature deviation. k1 is the first-order temperature compensation coefficient (unit: ns / ℃), used to describe the linear effect of temperature changes on clock deviation, set to k1 = 0.05ns / ℃ (meaning that for every 1℃ increase, the clock deviation increases linearly by 0.05ns). k2 is the second-order temperature compensation coefficient (unit: ns / ℃²), used to describe the nonlinear effect of temperature changes (e.g., the frequency-temperature curve of a crystal oscillator exhibits parabolic characteristics), set to k2 = 0.001ns / ℃² (meaning that for every 1℃ deviation of the temperature from T_cal, the nonlinear deviation increases by 0.001ns).

[0125] Step 208: Calculate the phase noise compensation caused by the vibration of the communication vehicle. The calculation formula is as follows:

The default K = 0.1 ns / g)

[0128] Step 209: Correct the local clock to achieve time synchronization with the clock module, ensuring dynamic adaptation to the network environment and maintaining clock synchronization accuracy. The calculation formula is as follows:

[0129] OS_corrected=OS_raw-(T_T+T_V)

[0130] Where OS_raw is the calculated uncorrected clock skew (in ns), and OS_corrected is the corrected clock skew (in ns).

[0139] (1) The device cryptographic protocol interaction includes:

[0140] Step 301: The cryptographic module integrates a quantum random number generator (QRNG) to collect photon polarization states in real time and generate a quantum entropy source QRNG_output. Simultaneously, it combines a chaotic mapping (Logisticμ = 3.999) to generate a chaotic sequence Chaos_sequence, which is then XORed with the quantum entropy source to generate the session key Sec. The calculation formula is as follows:

[0141] Sec=QRNG_output⊕Chaos_sequence

[0142] Step 302: When the modular device is connected, the cryptographic proxy module is used to collect hardware fingerprints (SHA3-256 (FPGA bit stream), acoustic features (MFCC coefficients + Gaussian mixture model) and dynamic power consumption signatures (power consumption trace of running specific instructions), and send authentication and encryption request messages to the cryptographic module.

[0143] Step 303: Upon receiving the data, the cryptographic module verifies it. If verification fails, it refuses to send the session key, determines that an attack may exist, and sends a power-off command to the corresponding modular device to the power module; if verification succeeds, it sends the session key to the cryptographic proxy module.

[0151] (1) The device power protocol interaction includes:

[0152] Step 401: After the modular device is powered on, the power proxy module sends a registration request message to the power module, carrying the device hardware fingerprint (SHA3-256), rated power (16-bit), security certificate (SM2 signature), and dynamic power consumption feature code information. This requests the power allocation required by the modular device.

[0153] Step 402: Upon receiving the power module, the certificate validity is verified, and the power consumption feature code is compared with the database to prevent cloned devices from accessing the system. If verification fails, power supply to the modular device is refused; if verification passes, power is dynamically allocated according to the power requirements of the modular device.

[0154] Step 403: The power module uses an LSTM neural network model, inputting historical power sequences (sampled every 1 second), device type, and task queue depth, to predict the modular device power consumption Ppred for the next 30 seconds, and dynamically pre-allocates power. This transforms traditional reactive power allocation into predictive power allocation, shortening the power supply response time for sudden load increases and avoiding instantaneous overload.

[0155] Step 404: The power proxy module monitors the device-side voltage in real time. If it finds that the voltage change does not meet the usage requirements of the modular device, it sends feedback to the power module in real time, and the power module makes dynamic adjustments.

[0156] Step 405: The power module receives the power-off command sent by the password module and directly cuts off the power to the corresponding modular device.

[0157] Step 406: When the power module detects a current greater than 110% of the rated value, it sends an overload power-off message to the power agent module of the modular device and cuts off the power supply.

Step 402: After receiving the power module, verify the validity of the certificate and compare it with the power consumption feature code database to prevent cloned devices from accessing the device; if the verification fails, refuse to supply power to the modular device; if the verification passes, dynamically allocate power according to the power requirements of the modular device. Step 403: The power module uses an LSTM neural network model, inputting historical power sequences, device type, and task queue depth, to predict the modular device power consumption Ppred for the next 30 seconds and dynamically pre-allocate power. This transforms traditional reactive power allocation into predictive power allocation, shortening the power supply response time for sudden load increases and avoiding instantaneous overload. Step 404: The power proxy module monitors the device-side voltage in real time. If it finds that the voltage change does not meet the usage requirements of the modular device, it sends feedback to the power module in real time, and the power module makes dynamic adjustments.
