[0029] Figure 1 is a flow chart of a method for testing a vehicle-mounted communication device according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0030] Step S102, controlling a target vehicle equipped with a target communication device to be tested and a reference vehicle equipped with a reference communication device to be tested to be in the same preset area, and controlling the target communication device and the reference communication device to receive radio frequency signals.

[0032] The above-mentioned target communication device may refer to a communication device to be tested mounted on a vehicle. The target communication device may include but is not limited to a vehicle-mounted terminal (Telematics Box, referred to as T-BOX), a vehicle-mounted navigation device, a vehicle-mounted wireless network device, etc. The target communication device may be determined according to actual needs and is not limited here.

[0033] The above-mentioned reference communication device may refer to a reference device used to test the target communication device. The device type of the reference communication device is the same as the device type of the target communication device. The reference communication device may be determined based on the specific target communication device, which is not limited here.

[0034] The above-mentioned preset area may refer to a pre-set area where the target communication device needs to be tested. There may be one or more preset areas. The specific location and range of the preset area may be determined according to actual needs and are not limited here. The RF performance of the target communication device to be tested mounted on the target vehicle in various environments may be tested to ensure the stability of the RF performance of the target vehicle in various actual environments.

[0035] The above-mentioned preset RF performance may refer to a pre-set RF capability that meets the RF performance requirements. The preset RF performance may include frequency range, power output, bandwidth, sensitivity, anti-interference capability and other aspects. The preset RF performance of the vehicle-mounted communication equipment may include the supported frequency range, transmit power, receiving sensitivity, anti-interference capability, etc. By pre-setting these performance requirements and passing tests, it is ensured that the vehicle-mounted communication equipment can provide stable and reliable communication services. The preset RF performance can be determined according to actual needs and is not limited here.

[0036] The above-mentioned radio frequency signal may refer to an electrical signal with a frequency within the radio wave band. The emission source of the radio frequency signal may be each actual test environment, that is, the actual radio frequency signal emission source in each preset area, which may be managed by the communication operator. This application is used to test the radio frequency performance of vehicle-mounted communication equipment in various actual environments, and may be used for wireless communication and wireless transmission. The radio frequency signal has a high frequency and a shorter wavelength, and may propagate in space and carry information.

[0037] In an optional embodiment, in the RF performance test of the vehicle-mounted communication device, the present application proposes to adopt a comparative test method to ensure the accuracy and comparability of the test results. Specifically, the target vehicle equipped with the target communication device to be tested and the reference vehicle equipped with the reference communication device can be controlled to be in the same preset area, and the target communication device and the reference communication device are controlled to receive RF signals. In the comparative test, the reference communication device plays a reference role, the device type of the reference communication device is the same as the device type of the target communication device, and the RF performance reaches a preset RF performance level; by allowing the target communication device and the reference communication device to receive RF signals at the same time, the performance of the target communication device and the reference communication device can be directly compared. By comparing the quality and stability of the RF signals received by the target communication device and the reference communication device, the performance of the target communication device can be evaluated to detect whether it meets the preset RF performance standards. The above steps can ensure the objectivity and reliability of the test results. Through comparative testing, the RF performance of the target communication device can be more accurately evaluated, potential problems can be found and improved, and by comparison with the reference communication device, the performance of the target communication device can be better understood, providing more reliable data and conclusions for RF performance testing.

[0038] Step S104, obtaining a target reception record generated by the target communication device and a reference reception record generated by the reference communication device.

[0039] Among them, the target reception record is used to represent the reception record generated by the target communication device receiving the RF sub-signal of the same frequency band in the RF signal, and the reference reception record is used to represent the reception record generated by the reference communication device receiving the RF sub-signal of the same frequency band.

[0040] The above-mentioned RF signals of the same frequency band may refer to RF signals within the same frequency range. In an optional embodiment, in the RF performance test of the vehicle-mounted communication equipment, the target reception record generated by the target communication equipment and the reference reception record generated by the reference communication equipment may be obtained, which can help evaluate the performance of the vehicle-mounted communication equipment when receiving RF signals. The target reception record is used to characterize the reception record generated by the target communication equipment receiving the RF sub-signal of the same frequency band in the RF signal. The target communication equipment will receive RF signals transmitted from other devices or base stations, and the RF signals will be demodulated and processed to eventually form a target reception record. The target reception record may include parameters such as the received signal strength, signal-to-noise ratio, and bit error rate, which are used to evaluate the performance of the target communication equipment. The performance of the vehicle-mounted communication device when receiving signals; the reference reception record is used to characterize the reception record generated by the reference communication device receiving the RF sub-signal of the same frequency band. When performing performance comparison, the reference communication device will receive the RF signal of the same frequency band and generate a reference reception record; by comparing the target reception record and the reference reception record, the performance difference between the target communication device and the reference communication device when receiving the signal of the same frequency band can be evaluated, thereby helping to optimize the performance of the vehicle-mounted communication device. By obtaining the reception records generated by the target communication device and the reference communication device, the present application can effectively evaluate the performance of the vehicle-mounted communication device when receiving RF signals, thereby guiding performance optimization and improvement work.

[0041] In particular, in the RF performance test of vehicle-mounted communication equipment, the present application takes into account that signals in different frequency bands will be affected by different propagation characteristics, interference and attenuation, etc. If signals in different frequency bands are used for comparison during testing, it is difficult to accurately evaluate the receiving performance of the target communication equipment. The present application proposes obtaining the reception records generated by the target communication equipment receiving the RF sub-signal of the same frequency band in the RF signal, and the reception records generated by the reference communication equipment receiving the RF sub-signal of the same frequency band. By determining the "RF signal of the same frequency band", it can be ensured that the reception performance of the target communication equipment and the reference communication equipment under the same signal conditions are compared during the test, so that the performance of the target equipment can be evaluated more accurately, and at the same time, errors caused by different frequency bands can be eliminated, thereby improving the credibility and accuracy of the test results.

[0042] Step S106: Determine the test result of the target communication device based on the target reception record and the reference reception record.

[0043] The test result is used to indicate whether the radio frequency performance of the target communication device reaches the preset radio frequency performance.

[0044] In an optional embodiment, in the RF performance test of the vehicle-mounted communication equipment, the target reception record and the reference reception record can be used for comparison to determine the test result of the target communication equipment. The target reception record is a data record collected when testing the target communication equipment, and the reference reception record is a data record collected using a reference equipment with known performance under the same test conditions. By comparing the target reception record and the reference reception record, it can be evaluated whether the RF performance of the target communication equipment meets the preset RF performance requirements. Specifically, the performance level of the target equipment can be judged by comparing indicators such as signal strength, signal-to-noise ratio, and bit error rate. If the test result of the target equipment is significantly different from the test result of the reference equipment, it may mean that the target equipment has performance problems or needs further optimization. Through the above steps, it can be ensured that the target communication equipment meets the preset requirements in terms of RF performance, so as to ensure that it can work normally and provide stable communication services in actual usage scenarios. Through comparative analysis based on the target reception record and the reference reception record, potential performance problems can be discovered and resolved in a timely manner, thereby improving the reliability and stability of the vehicle-mounted communication equipment.

[0045] In an embodiment of the present invention, a method for testing an in-vehicle communication device is provided. First, a target vehicle equipped with a target communication device to be tested and a reference vehicle equipped with a reference communication device are controlled to be in the same preset area, and the target communication device and the reference communication device are controlled to receive radio frequency signals. Then, a target reception record generated by the target communication device and a reference reception record generated by the reference communication device are obtained. Finally, based on the target reception record and the reference reception record, a test result of the target communication device is determined. It is easy to notice that the present application proposes to adopt a comparative test method to ensure the accuracy and comparability of the test results. By allowing the target communication device and the reference communication device to receive the RF signal at the same time, the performance of the target communication device and the reference communication device can be directly compared. By comparing the quality and stability of the RF signals received by the target communication device and the reference communication device, the performance of the target communication device can be evaluated to detect whether it meets the preset RF performance standards. The present application proposes to obtain the reception records generated by the RF sub-signals of the same frequency band in the RF signal received by the target communication device, and the reception records generated by the RF sub-signals of the same frequency band received by the reference communication device. By determining the RF signals of the same frequency band, it can be ensured that the reception performance of the target communication device and the reference communication device under the same signal conditions are compared during the test, and the performance of the target device can be evaluated more accurately. At the same time, it can also eliminate the errors caused by different frequency bands, improve the credibility and accuracy of the test results, and thus solve the technical problem of low efficiency in testing the RF performance of vehicle-mounted communication equipment in the related technology.

[0046] Optionally, the radio frequency signal includes multiple radio frequency sub-signals in different frequency bands; obtaining a target reception record generated by a target communication device and a reference reception record generated by a reference communication device includes: selecting any one of the multiple radio frequency sub-signals as the target radio frequency sub-signal; obtaining a reception record generated by the target communication device during the process of receiving the target radio frequency sub-signal to obtain a target reception record; obtaining a reception record generated by the reference communication device during the process of receiving the target radio frequency sub-signal to obtain a reference reception record.

[0047] The above-mentioned target RF sub-signal may refer to a RF signal in a pre-selected specific frequency band. For example, the target RF sub-signal may be selected from any one of the RF signals in different frequency bands such as N41, B39, B40, B41, GSM900, GSM1800, B1, B5, CDMA, N78, B3, B8 and WCDMA. The target RF sub-signal may be determined according to actual needs and is not limited here.

[0048] In an optional embodiment, in the RF performance test of the vehicle-mounted communication equipment, the performance of the target communication equipment and the reference communication equipment when receiving the target RF sub-signal can be compared and evaluated. Specifically, the present application takes into account that the RF signal is composed of multiple RF sub-signals in different frequency bands. In the test, one of the RF sub-signals can be selected as the target RF sub-signal for testing. This target RF sub-signal may be the RF signal frequency band that needs to be tested in the test, or it may be a typical sample representing the overall RF signal characteristics. In particular, the present application can determine multiple target RF sub-signals in sequence according to actual needs, and test each target RF sub-signal in sequence to test the vehicle-mounted communication equipment at each frequency. The RF performance of the target communication device under the same frequency band can be evaluated; the receiving records generated by the target communication device and the reference communication device when receiving the target RF sub-signal can be obtained respectively. The receiving records can include various parameters and indicators of the device in the process of receiving the signal, such as receiving power, signal-to-noise ratio, bit error rate, etc. By comparing the target receiving records with the reference receiving records, the performance of the target communication device can be evaluated and its condition when receiving the target RF sub-signal can be judged. The above steps evaluate the RF performance of the target communication device by comparing the performance of the target communication device and the reference communication device when receiving specific RF signals, which can help understand the performance of the device under signals in different frequency bands, guide product design and optimization, and improve the performance and stability of communication equipment.

[0049] Optionally, based on the target reception record and the reference reception record, determining the test result of the target communication device includes: determining the target similarity between the target reception record and the reference reception record; when the target similarity satisfies a preset similarity condition, determining the test result as that the RF performance of the target communication device reaches the preset RF performance; when the target similarity does not satisfy the preset similarity condition, determining the test result as that the RF performance of the target communication device does not reach the preset RF performance.

[0050] The above-mentioned preset similarity condition may refer to a preset condition set for determining the difference between the radio frequency performance of the target communication device and the radio frequency performance of the reference communication device. The preset similarity condition may be determined according to actual needs and is not limited here.

[0051] In an optional embodiment, in the RF performance test of the vehicle-mounted communication equipment, the target similarity between the target reception record and the reference reception record can be determined. Specifically, by comparing and analyzing the target reception record and the reference reception record, the similarity between the target reception record and the reference reception record can be determined. When the target similarity satisfies the preset similarity condition, that is, the performance data of the target reception record is slightly different from the performance data of the reference reception record, it can be determined that the RF performance of the target communication equipment has reached the preset RF performance standard; when the target similarity does not meet the preset similarity condition, that is, there is a large difference between the performance data of the target reception record and the performance data of the reference reception record, it can be determined that the RF performance of the target communication equipment does not meet the preset RF performance standard. By comparing and analyzing the target similarity between the target reception record and the reference reception record, it can be effectively judged whether the RF performance of the target communication equipment meets the preset standard, providing an important reference basis for subsequent performance evaluation and debugging.

[0052] Optionally, determining the target similarity between the target reception record and the reference reception record includes: obtaining a target reception sub-record in the target reception record corresponding to a first signal receiving end among multiple signal receiving ends of the target communication device, wherein the target reception sub-record is used to represent a record generated by the first signal receiving end receiving the target radio frequency sub-signal; obtaining a reference reception sub-record in the reference reception record corresponding to a second signal receiving end among multiple signal receiving ends of the reference communication device, wherein the reference reception sub-record is used to represent a record generated by the second signal receiving end receiving the target radio frequency sub-signal, and the second signal receiving end is of the same type as the first signal receiving end; and comparing the target reception sub-record with the reference reception sub-record to obtain the target similarity.

[0053] In an optional embodiment, in the RF performance test of the vehicle-mounted communication device, the acquisition and comparative analysis of the target reception record and the reference reception record can evaluate the reception performance of the target communication device, and obtain a target reception sub-record corresponding to a first signal receiving end among multiple signal receiving ends of the target communication device, and the target reception sub-record is used to represent the record generated by the first signal receiving end receiving the target RF sub-signal; the reference reception record may refer to a signal record received by the reference communication device, and a reference reception sub-record corresponding to a second signal receiving end among multiple signal receiving ends of the reference communication device can be obtained, and the reference reception sub-record is used to represent the record generated by the second signal receiving end receiving the target RF sub-signal, in particular, the second signal receiving end is similar to the first signal receiving end. The types are the same to ensure the accuracy of the comparison; after obtaining the target reception sub-record and the reference reception sub-record, it is necessary to compare and analyze the target reception sub-record and the reference reception sub-record. By comparing the similarity between the target reception sub-record and the reference reception sub-record, the receiving performance of the target communication device can be evaluated. The comparison process may include indicators such as signal quality, signal interference, and signal strength. The target similarity can be obtained through comparative analysis. The target similarity can reflect the difference between the receiving performance of the target device and the receiving performance of the reference device, and the performance of the target device in receiving signals can be evaluated. The above steps can effectively evaluate the receiving performance of the target device and provide a reference basis for performance optimization by obtaining and comparing the target reception record and the reference reception record.

[0054] In particular, in the RF performance test of the vehicle-mounted communication equipment, the present application compares the data records generated by the same type of signal receiving terminals of the target communication equipment and the reference communication equipment. Setting the same type of signal receiving terminals for comparing the data records of the test communication equipment and the reference communication equipment can ensure the accuracy and reliability of the test. By testing the same type of signal receiving terminals, two different devices are compared under the same environmental conditions, so as to more accurately evaluate the performance difference between the target communication equipment and the reference communication equipment. Using the same type of signal receiving terminals can also ensure the consistency of the test and the comparability of the test data. If different types of signal receiving terminals are used for comparative testing, it may lead to result deviations due to differences in the receiving terminals themselves, making the comparison results unreliable.

The higher the signal-to-noise ratio, the less interference the target communication device receives when receiving the signal, and the better the reception quality; the receiving end call comparison result is used to indicate the comparison result of the number of calls of the receiving end when the target communication device receives the signal and the number of calls of the receiving end when the reference communication device receives the signal.

[0058] In an optional embodiment, in the RF performance test of the vehicle-mounted communication equipment, the quality and stability of the RF signal received by the target communication equipment can be evaluated based on the received power comparison. When performing the received power comparison, the power similarity between the target received power and the reference received power can be determined.

The comparison result called by the receiving end can also provide information about the receiving performance of the target communication equipment, including comparison of receiving sensitivity, anti-interference capability, etc.; if it is found in the received power comparison that the power similarity is greater than or equal to the first preset threshold, it can be determined that the target similarity does not meet the preset similarity condition, which can indicate that the target communication equipment has some problems in receiving signals, such as insufficient sensitivity or poor anti-interference capability. At this time, the test results can be further analyzed to find out the problem and make corresponding adjustments and improvements to ensure that the performance of the communication equipment meets the expected requirements.

[0059] Optionally, determining the target similarity based on the signal-to-noise-interference ratio comparison result and the receiving end calling comparison result includes: when the signal-to-noise-interference ratio comparison result is that the signal-to-noise-interference similarity between the target signal-to-noise-interference ratio and the reference signal-to-noise-interference ratio is less than a second preset threshold, determining the target similarity based on the receiving end calling comparison result, wherein the target signal-to-noise-interference ratio is used to represent the signal-to-noise-interference ratio of the target radio frequency sub-signal received by the target communication device, and the reference signal-to-noise-interference ratio is used to represent the signal-to-noise-interference ratio of the target radio frequency sub-signal received by the reference communication device; when the signal-to-noise-interference ratio comparison result is that the signal-to-noise-interference similarity is greater than or equal to the second preset threshold, determining that the target similarity does not meet the preset similarity condition.

[0060] In an optional embodiment, in the radio frequency performance test of the vehicle-mounted communication device, the performance of the target communication device can be determined by comparing the similarity between the target signal-to-noise-interference ratio and the reference signal-to-noise-interference ratio.

The signal-to-noise-interference ratio is used to represent the ratio of signal to noise and is used to measure the quality of the signal received by the communication device. If the signal-to-noise-interference ratio comparison result shows that the similarity between the target signal-to-noise-interference ratio and the reference signal-to-noise-interference ratio is less than a second preset threshold, it can be determined that the signal quality received by the target communication device is significantly different from that of the reference device. Based on the comparison result called by the receiving end, the similarity of the target communication device can be determined, and the performance of the target communication device can be further evaluated.

[0062] In an optional embodiment, in the RF performance test of the vehicle-mounted communication device, when performing the receiving end call comparison, it can be determined whether the target receiving end call number and the reference receiving end call number are the same. The target receiving end call number represents the receiving end call number when the target communication device receives the target RF sub-signal, and the reference receiving end call number represents the receiving end call number when the reference communication device receives the target RF sub-signal; when performing the comparison, if the target receiving end call number is the same as the reference receiving end call number, it can be determined that the target similarity meets the preset similarity condition, that is, the target communication device performs similarly to the reference device when receiving the target RF signal, and meets the expected performance requirements; if the receiving end call comparison result shows that the target receiving end call number is different from the reference receiving end call number, further analysis can be performed to determine that the target similarity does not meet the preset similarity condition, indicating that the target communication device has performance differences or problems when receiving the target RF signal, and further debugging and optimization are required. The receiving end call comparison is used to evaluate the performance of the target communication device when receiving the RF signal to ensure that it meets the expected requirements and can work normally. Through the testing and analysis of the above steps, potential performance problems can be discovered and solved in a timely manner to ensure the normal operation and reliability of the vehicle-mounted communication equipment.

[0064] In an optional embodiment, in the radio frequency performance test of the vehicle-mounted communication equipment, the radio frequency performance of the target vehicle and the reference vehicle when they travel along a preset circular path in the same preset area can be tested. By controlling the target vehicle and the reference vehicle to start from different positions, the relative position and speed changes between vehicles on a real road can be simulated, so as to more realistically evaluate the performance of the vehicle-mounted communication equipment. The target vehicle and the reference vehicle can be controlled to travel along the preset circular path, and the target vehicle and the reference vehicle have the same driving direction, so as to ensure that the target vehicle and the reference vehicle maintain a certain relative position during the test, so as to effectively compare the communication performance between the target vehicle and the reference vehicle. Since the target vehicle and the reference vehicle start from different positions, the relative position and mutual influence between different vehicles on a real road can be simulated, so as to more comprehensively evaluate the performance of the vehicle-mounted communication equipment. Through the above steps, the performance of the vehicle-mounted communication equipment at different relative positions and speeds can be evaluated, including indicators such as signal transmission quality and communication stability. By comparing the performance of the target vehicle and the reference vehicle, the performance of the vehicle-mounted communication equipment in a complex environment can be better understood, providing a reference for further optimizing and improving the vehicle-mounted communication equipment.
