Description

Technical Field

[0001] This invention relates to the field of automotive communication terminal testing technology, specifically a testing process for automotive multi-mode terminals that integrates Starlink technology. Background Technology

[0002] With the rapid development of intelligent connected vehicle technology, the communication capabilities of in-vehicle terminals have become a core factor affecting driving experience and safety. Currently, automotive in-vehicle terminals mainly rely on terrestrial communication technologies such as 4G / 5G, Bluetooth, and WiFi, and their application scenarios are limited to urban roads and areas with good signal coverage, only enabling basic functions such as remote control, navigation, and vehicle status reporting.

[0003] In the field of integrating satellite communication with intelligent connected vehicles, existing technologies are still in the initial exploratory stage. Some research focuses on the development of automotive communication terminals based on traditional geostationary orbit satellites, but traditional satellites have drawbacks such as high latency and limited coverage, making it difficult to meet the needs of vehicles for low-latency, wide-coverage communication during driving. Starlink technology, as a representative of low-Earth orbit satellite constellation communication technology, has advantages such as low latency, wide coverage, and high bandwidth, and its integration with automotive terminals has become an industry trend. However, a mature multi-mode automotive terminal product and supporting testing system integrating Starlink technology have not yet been formed.

[0004] The existing automotive terminal testing process has significant shortcomings: First, the testing scenarios are not fully covered, failing to include scenarios with signal obstruction or weak coverage, such as remote mountainous areas, tree-lined roads, densely populated high-rise areas, and tunnels, which are necessary for Starlink communication requirements. This makes it impossible to verify the terminal's communication adaptability in complex terrains / environments. Second, environmental adaptability testing is insufficient, only conducting basic testing under normal temperature conditions and lacking testing in extreme environments such as high and low temperatures and temperature and humidity cycles. Starlink terminals may experience hardware failures and communication performance degradation in common extreme environments such as high-temperature exposure and low-temperature freezing. There is an urgent need for a multi-mode automotive terminal testing process that integrates Starlink technology to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-mode terminal testing process for automobiles that integrates Starlink technology, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-mode automotive terminal testing process integrating Starlink technology, comprising a testing preparation stage, physical testing, high and low temperature testing, communication quality testing, special scenario testing, fault tracing testing, and test result processing stage. The testing process comprehensively covers the multi-mode characteristics of Starlink communication and terrestrial communication integration, the complex environmental requirements of vehicle driving, and the quality verification requirements of the entire terminal lifecycle through an AI-assisted testing module and a dynamic threshold adjustment mechanism. Specifically, it includes: building a composite testing environment combining laboratory and field testing, configuring multi-dimensional testing equipment, setting basic qualification thresholds and dynamically optimizing them, conducting multi-dimensional testing in stages, achieving fault tracing through AI analysis, and finally generating a standardized testing report containing improvement suggestions.

[0007] Preferably, the AI-assisted detection module is integrated into the detection preparation stage and the entire detection implementation process, specifically including: real-time collection of raw data (including physical parameters, environmental parameters, and communication indicators) of each detection item, analysis of data fluctuation trends through a preset algorithm model, automatic identification of abnormal detection nodes and triggering secondary verification; in communication quality detection, the AI ​​module can predict the timing of Starlink satellite switching, synchronize the sampling frequency of the detection equipment in advance, ensure the integrity of data collection during the switching process, and the abnormal warning response time is ≤0.5 s.

[0008] Preferably, the dynamic threshold adjustment mechanism is based on adaptive optimization of real-time parameters of the detection environment and terminal type. Specifically, in field scene detection, if the measured altitude in remote mountainous areas exceeds the benchmark value of 1500 m, the qualified threshold for Starlink communication transmission rate is reduced by 1 Mbps for every 500 m increase (not less than 5 Mbps); in temperature and humidity cycle test, if the terminal is a special model for new energy vehicles, the high and low temperature limits are extended to -45℃ and 90℃ respectively to ensure compatibility with the extreme temperature environment around the battery compartment of new energy vehicles.

[0009] Preferably, the fault tracing detection includes hardware fault location and communication anomaly tracing. The specific steps are as follows: In physical detection, stress sensors are used to record the impact force distribution on the terminal shell to locate vulnerable areas; in communication quality detection, Starlink satellite IDs, ground base station signal parameters, and switching trigger conditions are recorded simultaneously to establish a correlation mapping between abnormal data and the environment and equipment status; the tracing results need to clearly identify the fault type (hardware damage / communication protocol conflict / insufficient environmental adaptation) and the corresponding improvement direction to provide data support for terminal iteration.

[0010] Preferably, the testing preparation stage adds compatibility adaptation testing equipment, including vehicle system simulators for different brands of cars (covering mainstream operating systems for fuel vehicles and new energy vehicles) and multi-specification interface conversion modules. The real-world scenarios are expanded to include desert uninhabited areas (areas prone to sandstorms, visibility ≤50 m) and high-altitude snowfields (altitude ≥2000 m, snow thickness ≥30 cm). An electromagnetic interference simulator is added to the laboratory environment to simulate the electromagnetic environment when automotive electronic devices (radar, navigation system) are working, and to verify the terminal's anti-electromagnetic interference capability (communication performance attenuation ≤10% when interference intensity ≤50 V / m).

[0011] Preferably, the communication quality test adds a multi-terminal networking collaborative test, specifically: select 3-5 terminals to be tested, install them on different vehicles in the same test fleet (50-100 m apart), and simultaneously connect them to the Starlink constellation and the ground communication network to test the rationality of bandwidth allocation, signal interference suppression capability, and collaborative communication latency (average latency ≤60 ms in network state) when multiple terminals transmit concurrently; in the single-mode communication test, the Starlink mode adds an anti-Doppler frequency offset test to verify the signal compensation capability of the terminal when the vehicle is traveling at high speed (vehicle speed ≥120 km / h), with a frequency offset compensation error ≤5 Hz.

[0012] Preferably, the high and low temperature detection adds an extreme temperature and road condition coupling test, specifically: the terminal is fixed on a simulated bump test platform (bump frequency 5-10 Hz, amplitude 5-10 mm), and continuously tested for 12 hours each in a -40℃ low temperature environment and an 85℃ high temperature environment, while simultaneously monitoring the terminal's communication stability and structural integrity. It is required that the number of communication interruptions during the coupling test be ≤2, and that there be no new damage to the outer shell; in the temperature and humidity cycle test, the humidity gradient is adjusted by 10% every 8 hours (60%-80% range) to simulate the scenario of drastic changes in humidity between day and night.

[0013] Preferably, in the special scenario detection, the tunnel area detection adds a new long-distance tunnel segment test (tunnel length ≥ 1000 m, divided into 200 m segments), recording the Starlink signal penetration depth and communication quality of each segment; the high-rise dense area detection adds tests at different time periods (morning rush hour and nighttime light-intensive periods), analyzing the superimposed impact of electromagnetic interference and light reflection on Starlink communication, requiring that the packet loss rate at each time period be ≤ 1%; the remote mountainous area detection adds a cross-altitude driving test (altitude span ≥ 1000 m), verifying the terminal's signal adaptation speed when altitude changes rapidly (signal recovery time ≤ 2s when altitude change rate ≥ 500 m / h).

[0014] Preferably, the testing equipment is equipped with an automatic calibration closed-loop module, which specifically includes: automatically calibrating the Starlink signal simulator, transmission rate tester, and other equipment using a standard signal source before testing, with a calibration error of ≤±2%; triggering a calibration verification every 12 hours during testing, and automatically pausing testing and completing calibration if the equipment deviation exceeds the threshold, with calibration data synchronized to the test report in real time to ensure the accuracy and traceability of the test results; and ensuring that the deviation of the synchronous test data between the testing terminal and the standard comparison terminal is ≤3%.

[0015] Preferably, the test result processing stage adds a user scenario customization module, which can adjust the weight of test items according to the terminal application scenario (such as long-distance freight, outdoor adventure, urban commuting): for long-distance freight scenarios, strengthen the test time and mileage for remote mountainous areas and long tunnels (mountainous driving ≥200 km, tunnel testing ≥3 tunnels); for outdoor adventure scenarios, increase the number of extreme temperature and humidity cycle tests (cycles ≥8 times); the customized test report should clearly indicate the scenario adaptability level (excellent / qualified / needs improvement) and provide targeted hardware reinforcement and software optimization suggestions to provide accurate inspection basis for the scenario-based application of the terminal.

[0016] Compared with existing technologies, this solution designs a multi-mode vehicle terminal testing process that integrates Starlink technology, which has the following advantages: The testing system is complete and comprehensive: This invention covers multiple dimensions of testing items, including physical performance, extreme environments, communication quality, and special scenarios. It not only sets up exclusive testing indicators for the low latency and wide coverage characteristics of Starlink communication, but also takes into account the needs of terrestrial communication and multi-mode switching. It solves the shortcomings of existing testing processes that are not fully covered by scenarios and have only one dimension, and achieves comprehensive verification of the full performance of the terminal.

[0017] Strong adaptability to environment and scenarios: Through a combination of laboratory simulation and field testing, it covers extreme environments such as high and low temperatures and temperature and humidity cycles, as well as complex real-world scenarios such as remote mountainous areas, tree-lined roads, densely populated high-rise areas, and tunnels, ensuring that the terminal can work stably and reliably in various environments in which the car is driving, thereby improving driving safety.

[0019] Please see Figure 1The technical solution provided by this invention is a multi-mode vehicle terminal testing process integrating Starlink technology. The process includes a testing preparation stage, physical testing, high and low temperature testing, communication quality testing, special scenario testing, fault tracing testing, and test result processing. The testing process, through an AI-assisted testing module and a dynamic threshold adjustment mechanism, comprehensively covers the multi-mode characteristics of Starlink communication and terrestrial communication integration, the complex environmental requirements of vehicle operation, and the quality verification requirements throughout the terminal's entire lifecycle. Specifically, it includes: building a composite testing environment combining laboratory and field testing; configuring multi-dimensional testing equipment; setting and dynamically optimizing basic qualification thresholds; conducting multi-dimensional testing in stages; achieving fault tracing through AI analysis; and finally generating a standardized testing report containing improvement suggestions.

[0020] The AI-assisted detection module is integrated into the detection preparation stage and the entire detection implementation process. Specifically, it includes: real-time collection of raw data (including physical parameters, environmental parameters, and communication indicators) of each detection item; analysis of data fluctuation trends through a preset algorithm model; automatic identification of abnormal detection nodes and triggering secondary verification; in communication quality detection, the AI ​​module can predict the timing of Starlink satellite switching, synchronize the sampling frequency of the detection equipment in advance, ensure the integrity of data collection during the switching process, and the abnormal warning response time is ≤0.5s.

[0021] The dynamic threshold adjustment mechanism is based on adaptive optimization of real-time parameters of the detection environment and terminal type. Specifically, in field scene detection, if the measured altitude in remote mountainous areas exceeds the benchmark value of 1500m, the qualified threshold for Starlink communication transmission rate is reduced by 1Mbps for every 500m increase (with a minimum of 5Mbps); in temperature and humidity cycle test, if the terminal is a special model for new energy vehicles, the high and low temperature limits are extended to -45℃ and 90℃ respectively to ensure compatibility with the extreme temperature environment around the battery compartment of new energy vehicles.

[0022] The fault tracing and detection includes hardware fault location and communication anomaly tracing. The specific steps are as follows: In physical detection, stress sensors are used to record the impact force distribution on the terminal shell to locate vulnerable areas; in communication quality detection, Starlink satellite IDs, ground base station signal parameters, and switching trigger conditions are recorded simultaneously to establish a correlation mapping between abnormal data and the environment and equipment status; the tracing results need to clearly identify the fault type (hardware damage / communication protocol conflict / insufficient environmental adaptation) and the corresponding improvement direction to provide data support for terminal iteration.

[0023] The testing preparation phase includes the addition of compatibility testing equipment, including vehicle system simulators for different brands of cars (covering mainstream operating systems for fuel vehicles and new energy vehicles) and multi-specification interface adapter modules. The real-world scenarios have been expanded to include desert uninhabited areas (areas prone to sandstorms, visibility ≤50m) and high-altitude snowfields (altitude ≥2000m, snow thickness ≥30cm). An electromagnetic interference simulator has been added to the laboratory environment to simulate the electromagnetic environment of automotive electronic devices (radar, navigation system) during operation and to verify the terminal's anti-electromagnetic interference capability (communication performance attenuation ≤10% when interference intensity ≤50V / m).

[0024] The communication quality testing now includes a multi-terminal network collaborative test. Specifically, 3-5 terminals to be tested are selected and installed on different vehicles in the same test fleet (50-100m apart). They are simultaneously connected to the Starlink constellation and the ground communication network. The test assesses the rationality of bandwidth allocation, signal interference suppression capability, and collaborative communication latency (average latency ≤60ms in network state) during concurrent transmission of multiple terminals. In single-mode communication testing, the Starlink mode now includes an anti-Doppler frequency offset test to verify the terminal's signal compensation capability when the vehicle is traveling at high speed (≥120km / h), with a frequency offset compensation error ≤5Hz.

[0025] The high and low temperature testing now includes an extreme temperature and road condition coupling test. Specifically, the terminal is fixed on a simulated bump test bench (bump frequency 5-10Hz, amplitude 5-10mm) and continuously tested for 12 hours each in environments with a low temperature of -40℃ and a high temperature of 85℃. The terminal's communication stability and structural integrity are monitored simultaneously. The coupling test requires that the number of communication interruptions be ≤2 times and that there be no new damage to the outer shell. In the temperature and humidity cycle test, the humidity gradient is adjusted by 10% every 8 hours (60%-80% range) to simulate a scenario of drastic changes in humidity between day and night.

[0026] In the special scenario detection, the tunnel area detection adds a new long-distance tunnel segment test (tunnel length ≥ 1000m, divided into 200m segments), recording the Starlink signal penetration depth and communication quality of each segment; the high-rise dense area detection adds tests at different time periods (morning rush hour and nighttime light-intensive periods), analyzing the superimposed impact of electromagnetic interference and light reflection on Starlink communication, requiring a packet loss rate ≤ 1% for each time period; the remote mountainous area detection adds a cross-altitude driving test (altitude span ≥ 1000m), verifying the terminal's signal adaptation speed when altitude changes rapidly (signal recovery time ≤ 2s when altitude change rate ≥ 500m / h).

[0027] The newly added automatic calibration closed-loop module of the testing equipment is as follows: before testing, the Starlink signal simulator, transmission rate tester and other equipment are automatically calibrated by a standard signal source, with a calibration error of ≤±2%; during the testing process, a calibration verification is triggered every 12 hours. If the equipment deviation exceeds the threshold, the testing is automatically paused and the calibration is completed. The calibration data is synchronized to the test report in real time to ensure the accuracy and traceability of the test results; the deviation of the synchronous test data between the testing terminal and the standard comparison terminal is ≤3%.

[0028] The newly added user scenario customization module in the test result processing stage can adjust the weight of test items according to the terminal application scenario (such as long-distance freight, outdoor adventure, urban commuting): for long-distance freight scenarios, the test duration and mileage of remote mountainous areas and long tunnels are strengthened (mountainous driving ≥200km, tunnel testing ≥3 tunnels); for outdoor adventure scenarios, the number of extreme temperature and humidity cycle tests is increased (cycles ≥8 times); the customized test report should clearly indicate the scenario adaptability level (excellent / qualified / needs improvement) and provide targeted hardware reinforcement and software optimization suggestions to provide accurate inspection basis for the scenario-based application of the terminal.

The automotive multi-mode terminal testing process integrating Starlink technology according to claim 1, characterized in that: In the special scenario detection, the tunnel area detection adds a new long-distance tunnel segment test (tunnel length ≥ 1000 m, divided into 200 m segments), recording the Starlink signal penetration depth and communication quality of each segment; the high-rise dense area detection adds tests at different time periods (morning rush hour and nighttime light-intensive periods), analyzing the superimposed impact of electromagnetic interference and light reflection on Starlink communication, requiring a packet loss rate ≤ 1% for each time period; the remote mountainous area detection adds a cross-altitude driving test (altitude span ≥ 1000 m), verifying the terminal's signal adaptation speed when altitude changes rapidly (signal recovery time ≤ 2 s when altitude change rate ≥ 500 m / h).

9. The automotive multi-mode terminal testing process integrating Starlink technology according to claim 2, characterized in that: The newly added automatic calibration closed-loop module of the testing equipment is as follows: before testing, the Starlink signal simulator, transmission rate tester and other equipment are automatically calibrated by a standard signal source, with a calibration error of ≤±2%; during the testing process, a calibration verification is triggered every 12 hours. If the equipment deviation exceeds the threshold, the testing is automatically paused and the calibration is completed. The calibration data is synchronized to the test report in real time to ensure the accuracy and traceability of the test results; the deviation of the synchronous test data between the testing terminal and the standard comparison terminal is ≤3%.

10. The automotive multi-mode terminal testing process integrating Starlink technology according to claim 1, characterized in that: The newly added user scenario customization module in the test result processing stage can adjust the weight of test items according to the terminal application scenario (such as long-distance freight, outdoor adventure, urban commuting): for long-distance freight scenarios, the test duration and mileage of remote mountainous areas and long tunnels are strengthened (mountainous driving ≥200 km, tunnel testing ≥3 tunnels); for outdoor adventure scenarios, the number of extreme temperature and humidity cycle tests is increased (cycles ≥8 times); the customized test report should clearly indicate the scenario adaptability level (excellent / qualified / needs improvement) and provide targeted hardware hardening and software optimization suggestions to provide accurate inspection basis for the scenario-based application of the terminal.
