A person of ordinary skill in the art will appreciate that, with the evolution of the test standard determination system and the emergence of new business scenarios, the technical solution provided in the embodiments of the present application is equally applicable to similar technical problems.

[0062] The following describes it in detail with reference to specific embodiments.

[0063] In this embodiment, the method for determining the test standard is applied in the server.

[0064] The present invention provides a method for determining a test standard, which comprises: determining a signal scenario file corresponding to at least two target frequency bands that a positioning module needs to test; transmitting an analog signal of the target frequency band based on the signal scenario file by a signal generator; obtaining the signal strength of the analog signal received by the positioning module; and determining a target test standard required for each target frequency band based on the difference between the signal strength corresponding to each target frequency band and the reference signal strength, and the dependency between the target frequency bands in the positioning module, wherein the target test standard comprises a target transmission parameter of the analog signal, and a target signal strength of the analog signal received by the positioning module.

[0065] See also Figure 2 , is a flow chart of an embodiment of a method for determining a test standard in an embodiment of the present application, and the method for determining a test standard includes:

[0066] 101. Determine signal scenario files corresponding to at least two target frequency bands that the positioning module needs to test.

[0067] In an embodiment of the present application, the positioning module may include a GNSS module, which is generally composed of components such as a GNSS receiver, an antenna, a processor, and a memory. The GNSS module receives signals from multiple satellite navigation systems such as the Global Positioning System (GPS), the Galileo Satellite Navigation System, the GLONASS system, and the Beidou Navigation System, and uses the principle of triangulation to calculate the location of the device. After the signal is received, the processor in the module will interpret the signal and calculate the longitude, latitude, altitude and other location information of the device, and then transmit this information to the application for further processing.

[0068] Among them, GNSS modules can support one or more frequency bands, which are usually used by different satellite navigation systems. Each system has its own specific frequency bands and signal characteristics. GNSS modules have different configurations in terms of frequency band support, which are mainly determined by the design of the module and the application requirements.

[0069] For example, the frequency bands may include: L1 frequency band, L2 frequency band and L5 frequency band, etc. The center frequency of the L1 frequency band is: 1575.42 MHz; the center frequency of the L2 frequency band is: 1227.60 MHz; the center frequency of the L5 frequency band is: 1176.45 MHz.

[0070] Among them, according to the number of frequency bands and satellite navigation systems supported, GNSS modules can be divided into the following types: single-frequency single-constellation system positioning module: only supports one frequency band of one satellite navigation system; single-frequency multi-constellation system positioning module: supports one frequency band, but supports multiple satellite navigation systems at the same time; dual-frequency multi-constellation system positioning module: supports two frequency bands and supports multiple satellite navigation systems at the same time; multi-frequency multi-constellation system positioning module: supports multiple frequency bands and multiple satellite navigation systems at the same time. This module can achieve higher accuracy and more reliable positioning performance than dual-frequency.

[0071] In some embodiments, the positioning module may be a multi-frequency multi-constellation system positioning module.

[0072] The target frequency band refers to the frequency band supported by the positioning module, which may include multiple frequency bands.

[0073] The signal scenario file includes a signal transmitted by a simulated satellite navigation system on a frequency band, that is, a simulated signal corresponding to the frequency band. Different signal scenario files may include simulated signals corresponding to different frequency bands.

[0074] In some embodiments, the simulation signal may be generated by a signal simulator, and the signal simulator may simulate signals transmitted by different satellite navigation systems in different frequency bands.

[0075] For example, the frequency bands may include: L1 frequency band, L2 frequency band and L5 frequency band. The signal transmitted on the L1 frequency band can be simulated by a signal simulator to obtain the analog signal corresponding to the L1 frequency band, which is stored in signal scenario file 1; the signal transmitted on the L2 frequency band can be simulated by a signal simulator to obtain the analog signal corresponding to the L2 frequency band, which is stored in signal scenario file 2; the signal transmitted on the L5 frequency band can be simulated by a signal simulator to obtain the analog signal corresponding to the L5 frequency band, which is stored in signal scenario file 5, so that multiple signal scenario files can be obtained, each of which stores the analog signals corresponding to different frequency bands.

[0076] In some embodiments, the step of “determining the signal scenario files corresponding to at least two target frequency bands that the positioning module needs to test” may include the following operations:

[0077] Obtain product attribute information of the positioning module;

[0078] According to the supported frequency band information in the product attribute information, determine the target frequency band that the positioning module needs to test;

[0079] A signal scene file corresponding to the target frequency band is determined from a plurality of candidate signal scene files.

[0080] The product attribute information may include the supported frequency band information of the positioning module, that is, the frequency bands supported by the positioning module, for example, supporting the L1 frequency band and the L2 frequency band, etc.

[0081] The product attribute information of the positioning module may be obtained by loading a configuration file corresponding to the positioning module and reading the product attribute information from the configuration file.

[0082] In the embodiment of the present application, after the product attribute information is acquired, the frequency band supported by the positioning module included in the attribute information can be used as the target frequency band that the positioning module needs to test.

[0083] For example, the frequency bands supported by the positioning module may include the L1 frequency band and the L2 frequency band, and the L1 frequency band and the L2 frequency band may be used as the target frequency bands that the positioning module needs to test.

[0084] In some embodiments, the product attribute information may also include other information, such as data transmission protocol, working status, etc., and other functional items that need to be tested in the positioning module can be determined based on this information, and then other functionalities can be tested.

[0085] 102. Transmit a simulation signal of a target frequency band based on a signal scenario file through a signal generator.

[0086] Among them, the signal generator is a device that can provide electrical signals of various frequencies, waveforms and output levels, also known as a signal source or oscillator. The principle of the signal generator is mainly to generate a low-frequency sinusoidal oscillation signal through the master oscillator, and this signal is amplified by the voltage amplifier to meet the voltage output amplitude requirements. After that, the signal can directly output the voltage through the output attenuator, and the master oscillator output adjustment potentiometer can be used to adjust the output voltage. This principle enables the signal generator to generate stable and adjustable electrical signals.

[0087] Among them, transmitting an analog signal of a target frequency band based on a signal scenario file through a signal generator may include: connecting the signal generator, sending the signal scenario file to the signal generator, and controlling the signal generator to send the analog signal in the signal scenario file (that is, the analog signal corresponding to the target frequency band).

[0088] In some embodiments, when transmitting an analog signal through a signal generator, the transmission parameters of the signal generator may be configured, for example, the transmission parameters may include transmission power, etc. The transmission power of a signal refers to the energy intensity radiated by a radio transmitter in the form of electromagnetic waves through an antenna within a given frequency band. It is an important parameter for measuring the ability of a wireless device to send signals, and directly affects the transmission distance, penetration ability and reception quality of the signal. The size of the transmission power determines the strength and coverage of the radio signal, and is one of the important indicators for evaluating the performance of wireless devices.

[0089] In the embodiment of the present application, the initial transmission power can be preset as a transmission parameter of the signal generator.

[0090] For example, the target frequency band may include the L1 frequency band and the L2 frequency band. Then, the signal scenario file 1 corresponding to the L1 frequency band and the signal scenario file 2 corresponding to the L2 frequency band may be sent to the signal generator, and then the signal generator is controlled to transmit the analog signal 1 in the signal scenario file 1 and the analog signal 2 in the signal scenario file 2.

[0091] 103. Obtain the signal strength of the analog signal received by the positioning module.

[0092] After receiving the analog signal, the positioning module can analyze the analog signal to determine the signal strength of the received analog signal, obtain signal information, and then send the signal information to the server. The signal information may include frequency band, signal strength, etc. In this way, the signal strength of the analog signal received by the positioning module can be obtained through the signal information.

[0093] For example, after the positioning model receives the analog signal 1 corresponding to the L1 frequency band, it can determine that the signal strength of the received analog signal 1 is n, and then it can send signal information 1 to the server, which includes: the signal strength of the analog signal 1 received in the L1 frequency band is n.

[0094] 104. Based on the difference between the signal strength corresponding to each target frequency band and the reference signal strength, and the dependency between the target frequency bands in the positioning module, determine the target test standard required for each target frequency band.

[0095] In the positioning module, the dependency between various frequency bands is mainly reflected in how they work together to improve positioning accuracy, stability and anti-interference capabilities.

[0096] In some embodiments, the signal strength difference requirements between multiple frequency bands supported by the positioning module can be set according to actual needs. If there are signal strength difference requirements between the frequency bands, it can be determined that there is a dependency between the frequency bands; if there are no signal strength difference requirements between the frequency bands, it can be determined that there is no dependency between the frequency bands.

[0097] The signal strength difference requirement between frequency bands refers to the difference in signal strength received by the positioning module in different frequency bands.

[0098] The reference signal strength refers to the signal strength of the analog signal that is expected to be received by the receiving end for each frequency band, and different reference signal strengths can be set for different frequency bands.

[0099] In the implementation of the present application, the target test standard may include a target transmission parameter of the analog signal and a target signal strength of the analog signal received by the positioning module, wherein the target transmission parameter may be transmission power.

[0100] In some embodiments, in order to determine the test standard to meet the different dependencies of each target frequency band, the step of "determining the target test standard required for each target frequency band based on the difference between the signal strength corresponding to each target frequency band and the reference signal strength, and the dependency between the target frequency bands in the positioning module" may include the following operations:

[0101] Determine a first target frequency band that has no dependency relationship among at least two target frequency bands;

[0102] If the signal strength corresponding to the first target frequency band is the same as the reference signal strength, determining the first target transmission parameter based on the transmission power of the signal generator, and determining the first target signal strength based on the reference signal strength;

[0103] Based on the first target transmission parameter and the first target signal strength, a first target test standard corresponding to the first target frequency band is obtained.

[0104] The first target frequency band refers to a target frequency band that does not have a dependency relationship among the target frequency bands that the positioning module needs to test.

[0105] Specifically, it can be determined whether there is a signal strength difference requirement for multiple target frequency bands to determine whether there is a dependency between the target frequency bands. A target frequency band that does not have a signal strength difference requirement can be used as the first target frequency band.

[0106] In an embodiment of the present application, for first target frequency bands that have no dependency relationship, the target test standard corresponding to each first target frequency band, that is, the first target test standard, can be determined respectively according to the signal strength corresponding to each first target frequency band and the reference signal strength.

[0107] Specifically, for each first target frequency band, the target test standard may be determined as follows:

[0108] The signal strength corresponding to the first target frequency band is compared with the reference signal strength corresponding to the first target frequency band. If the signal strength is the same as the reference signal strength, the transmission power of the current signal generator can be used as the first target transmission parameter corresponding to the first target frequency band, and the first target signal strength can be determined based on the reference signal strength corresponding to the first target frequency band. In this way, the first target transmission parameter and the first target signal strength can be used as the first target test standard corresponding to the first target frequency band.

[0109] Determining the first target signal strength based on the reference signal strength may include: determining a signal strength range according to the reference signal strength and a preset value, and using the signal strength within the signal strength range as the first target signal strength.

[0110] For example, the reference signal strength corresponding to the first target frequency band may be 43DB, and the preset value may be 2. Then, according to 43-2 and 43+2, the signal strength range may be 41-45DB, and the first target signal strength may be 41-45DB.

[0111] In some embodiments, the preset value can be adjusted according to the actual application scenario and is not limited here.

[0112] For example, the current signal generator's transmission power can be n, and the first target signal strength can be 41-45 DB, then the first target test standard for the first target frequency band can be obtained as follows: the signal generator's transmission power: n, and the signal strength of the positioning module receiving signal is 41-45 DB. Then, the first target frequency band of the positioning module can be tested according to the first target test standard.

[0113] In some embodiments, in order to obtain the test standard corresponding to the target frequency band, the signal generator may be calibrated, and the method may further include the following steps:

[0114] If the signal strength corresponding to the first target frequency band is different from the reference signal strength, calculating a first difference between the signal strength corresponding to the first target frequency band and the reference signal strength;

[0115] Adjust the transmit power value of the signal generator based on the first difference to obtain a target transmit power value;

[0116] An analog signal of the first target frequency band is transmitted based on the target transmission power by a signal generator until the signal strength of the analog signal received by the positioning module is the same as the reference signal strength. The first target transmission parameters are determined based on the target transmission power, and the first target signal strength is determined based on the reference signal strength to obtain the first target test standard corresponding to the first target frequency band.

[0117] The first difference represents the difference between the signal strength of the analog signal of the first target frequency band received by the positioning module and the reference signal strength corresponding to the first target frequency band.

[0118] Specifically, the signal strength corresponding to the first target frequency band is compared with the reference signal strength corresponding to the first target frequency band. If the signal strength is different from the reference signal strength, the difference between the signal strength and the reference signal strength can be calculated to obtain the first difference.

[0119] Wherein, adjusting the transmit power value of the signal generator according to the first difference may include increasing or decreasing the transmit power value. If the first difference is greater than 0, it means that the signal strength is greater than the reference signal strength, and the transmit power of the signal generator may be further reduced, thereby reducing the signal strength of the analog signal of the first target frequency band received by the positioning module to meet the reference signal strength; if the first difference is less than 0, it means that the signal strength is less than the reference signal strength, and the transmit power of the signal generator may be further increased, thereby increasing the signal strength of the analog signal of the first target frequency band received by the positioning module to meet the reference signal strength.

[0120] For example, the difference between the signal strength corresponding to the first target frequency band and the reference signal strength corresponding to the first target frequency band may be 2DB, and the transmit power of the signal generator may be increased by 2DB to obtain the target transmit power value.

[0121] Furthermore, after adjusting the transmission power of the signal generator, the analog signal of the first target frequency band can be transmitted again according to the target transmission power value obtained after the adjustment, and the signal strength of the analog signal received by the positioning module can be continued to be obtained. The signal strength is compared with the reference signal strength again to determine whether the signal strength is the same as the reference signal strength. If not, the transmission frequency of the signal generator can be further adjusted according to the difference between the signal strength and the reference signal strength until the signal strength of the analog signal received by the positioning module is the same as the reference signal strength. At this time, the transmission power after the last adjustment can be used as the first target transmission parameter, and the first target signal strength determined according to the reference signal strength, and the first target transmission parameter, can be used as the first target test standard for the first target frequency band.

[0122] In some embodiments, in order to obtain an accurate test standard, the method may further include the following steps:

[0123] If the number of times the transmit power value of the signal generator is adjusted exceeds a preset number, calibration failure information of the target test standard of the first target frequency band is generated, and the calibration failure information is fed back to the tester.

[0124] The number of times the transmit power value of the signal generator is adjusted refers to the number of times the transmit power of the signal generator is adjusted when the signal strength of the analog signal in the first target frequency band received by the positioning module does not meet the reference signal strength.

[0125] The preset number of times refers to the number of times the signal generator is allowed to calibrate the transmission power, and the preset number of times can be set according to actual conditions. For example, the preset number of times can be 10 times, etc.

[0126] Among them, the calibration failure information indicates that in the calibration test of the analog signal in the first target frequency band, adjusting the transmission power of the signal generator still fails to make the signal strength meet the reference signal strength. In this case, the calibration failure information can be fed back to the tester to enable the tester to confirm and analyze the cause of the failure.

[0127] For example, see Figure 3 , Figure 3 It is a schematic diagram of the calibration flow of the method for determining the test standard provided in the embodiment of the present application. Figure 3 The calibration process of the test standard for the positioning module is shown, which can be specifically as follows:

[0128] First, the signal generator can be configured to set the relevant parameters of the application scenario to be used in the signal generator;

[0129] Acquire product configuration information of the positioning module, and determine test frequency band information of the positioning module according to the product configuration information, where the test frequency band information may include a target frequency band supported by the positioning module;

[0130] According to the target frequency band in the test frequency band information, a signal scenario file corresponding to each target frequency band is obtained, where the signal scenario file includes a simulation signal corresponding to the target frequency band;

[0131] Connect the signal generator and test it to determine whether the connection of the signal generator is normal;

[0132] If the connection of the signal generator is abnormal, the calibration is determined to have failed, and then a calibration failure message is generated and fed back to the tester, so that the tester can check the signal generator and trigger the calibration process again;

[0133] If the signal generator is connected normally, the initial transmission power of the signal generator can be set;

[0134] Determining whether the number of calibrations reaches a preset number, wherein the number of calibrations may indicate the number of times the transmit power of the signal generator is calibrated;

[0135] If the calibration times reach the preset times, the calibration is determined to have failed, and then calibration failure information is generated and fed back to the tester, so that the tester can check according to the calibration failure information and trigger the calibration process again;

[0136] If the calibration times do not reach the preset times, the signal generator may be controlled to play the signal scene file, that is, the analog signal in the signal scene file is transmitted by the signal generator according to the initial transmission power;

[0137] Connect the fixture that fixes the positioning module through the power supply, power on the positioning module, control the positioning module to enter the working state, and receive the analog signal;

[0138] Obtain the signal strength of the analog signal received by the positioning module, and then determine whether the signal strength reaches the reference signal strength;

[0139] If the signal strength reaches the reference signal strength, the test standard can be determined according to the initial transmission power and the reference signal strength, indicating that the calibration is successful. Then, the information of successful calibration can be fed back to the tester so that the tester can record the test standard for subsequent positioning module testing. At this point, the calibration process ends and each connection can be disconnected.

[0140] If the signal strength does not reach the reference signal strength, the difference between the signal strength and the reference signal strength can be calculated, and the transmission power of the signal generator can be adjusted according to the difference, and then return to the step of "determining whether the number of calibrations reaches the preset number".

[0141] In some embodiments, in order to determine the test standard to meet the different dependencies of each target frequency band, the step of "determining the target test standard required for each target frequency band based on the difference between the signal strength corresponding to each target frequency band and the reference signal strength, and the dependency between the target frequency bands in the positioning module" may include the following operations:

[0142] determining at least one group of target frequency bands having a dependency relationship among at least two target frequency bands;

[0143] If the signal strength corresponding to the second target frequency band is the same as the reference signal strength, determining the second target transmission parameter based on the transmission power of the signal generator, and determining the second target signal strength based on the reference signal strength;

[0144] Based on the second target transmission parameter and the second target signal strength, obtaining a second target test standard corresponding to the second target frequency band;

[0145] According to the second target test standard, a third target test standard corresponding to a third target frequency band belonging to the same group of target frequency bands as the second target frequency band is determined.

[0146] Among them, each group of target frequency bands refers to multiple target frequency bands with dependencies among the target frequency bands that the positioning module needs to test. Each group of target frequency bands includes a second target frequency band that is dependent and a third target frequency band that is dependent on the second target frequency band. That is, there is a signal strength difference requirement between the second target frequency band and the third target frequency band.

[0147] For example, in the same group of target frequency bands, the signal strength difference requirement between the second target frequency band and the third target frequency band may include: the difference between the signal strength of the analog signal received by the positioning module in the second target frequency band and the signal screen strength of the analog signal received in the third target frequency band meets the preset difference.

[0148] Specifically, it can be determined whether there is a signal strength difference requirement for multiple target frequency bands to determine whether there is a dependency between the target frequency bands. The target frequency bands that have a signal strength difference requirement can be taken as a group of target frequency bands.

[0149] In an embodiment of the present application, for a group of target frequency bands that have a dependent relationship, the target test standard corresponding to the second target frequency band in each group of target frequency bands, that is, the second target test standard, can be first determined. Furthermore, based on the signal strength difference requirement between the second target frequency band and the third target frequency band, the third target test standard corresponding to the third target frequency band can be determined according to the second target test standard.

[0150] Specifically, for each second target frequency band, the target test standard may be determined as follows:

[0151] The signal strength corresponding to the second target frequency band is compared with the reference signal strength corresponding to the second target frequency band. If the signal strength is the same as the reference signal strength, the transmission power of the current signal generator can be used as the second target transmission parameter corresponding to the second target frequency band, and the second target signal strength can be determined according to the reference signal strength corresponding to the second target frequency band. In this way, the second target transmission parameter and the second target signal strength can be used as the second target test standard corresponding to the second target frequency band.

[0152] Determining the second target signal strength based on the reference signal strength may include: determining two signal strength ranges according to the reference signal strength and a preset value, and using the signal strength within the signal strength range as the second target signal strength.

[0153] For example, the reference signal strength corresponding to the second target frequency band may be 41DB, and the preset value may be 2. Then, according to 41-2 and 41+2, the signal strength range may be 39-43DB, and the second target signal strength may be 39-43DB.

[0154] In some embodiments, for target frequency bands with a dependency relationship, in order to improve the efficiency of determining the test standard, the step of “determining, according to the second target test standard, a third target test standard corresponding to a third target frequency band that belongs to the same group of target frequency bands as the second target frequency band” may include the following operations:

[0155] Calculate the difference between the signal strength corresponding to the third target frequency band and the signal strength corresponding to the second target frequency band to obtain a second difference;

[0156] If the second difference does not meet the reference difference, signal strength abnormality information of the second target frequency band and the third target frequency band is generated, and the signal strength abnormality information is fed back to the tester.

[0157] Among them, the signal strength corresponding to the third target frequency band refers to the signal strength of the analog signal of the third target frequency band received by the positioning module; the signal strength corresponding to the second target frequency band refers to the signal strength of the analog signal of the second frequency band received by the positioning module.

[0158] The reference difference refers to a signal strength difference corresponding to a signal strength difference requirement between the second target frequency band and the third target frequency band.

[0159] For example, the signal strength difference between the second target frequency band and the third target frequency band may correspond to a signal strength difference of 2 DB, and the reference difference may be 2 DB.

[0160] The second difference value not satisfying the reference difference value may include that the second difference value is greater than or less than the reference difference value.

[0161] In an embodiment of the present application, if the second difference does not meet the reference difference, the operation needs to be terminated and the tester needs to be informed to inspect and confirm. That is, signal strength abnormality information of the second target frequency band and the third target frequency band can be generated, and the signal strength abnormality information can be fed back to the tester so that the tester can analyze the positioning module and the signal generator according to the signal strength abnormality information.

[0162] In some embodiments, the method may further include the following steps:

[0163] If the second difference satisfies the reference difference, adjusting the second target signal strength according to the second difference to obtain an adjusted target signal strength;

[0164] A third target test standard is determined based on the second target transmission parameter and the adjusted target signal strength.

[0165] The second difference value satisfying the reference difference value may include the second difference value being equal to the reference difference value.

[0166] In an embodiment of the present application, if the second difference satisfies the reference difference, the second target signal strength in the second target test standard corresponding to the second target frequency band can be adjusted according to the second difference to obtain the adjusted target signal strength, and then the third target test standard corresponding to the target third target frequency band can be obtained according to the second target transmission parameters and the adjusted target signal strength.

[0167] Adjusting the second target signal strength according to the second difference may include reducing the second target signal strength according to the second difference to obtain an adjusted target signal strength.

[0168] For example, the second target signal strength may include: 39-44 DB, the reference difference value may be 2 DB, then 39-2 and 44-2 may be calculated, so that the adjusted target signal strength is 37-42 DB.

[0169] In some embodiments, in order to obtain accurate test standards, for the second target frequency band and the third target frequency band that are dependent on each other, if the test standard of the second target frequency band is abnormal during the calibration process, there is no need to continue to determine the test standard of the third target frequency band. The reason why the test standard of the second target frequency band is abnormal during the calibration process can be analyzed, and the calibration process of the test standard of the second target frequency band can be re-executed until the test standard of the second target frequency band is successfully determined. The test standard of the third target frequency band can be determined based on the test standard of the second frequency band. In this way, the test standards corresponding to each target frequency band can be obtained.

[0170] Furthermore, after determining the test standard for each target frequency band, each target frequency band of the positioning module can be quickly tested according to the test standard to obtain the test result, thereby improving the test efficiency of the positioning module.

[0171] The embodiment discloses a method for determining a test standard, including: determining the signal scenario files corresponding to at least two target frequency bands that the positioning module needs to test; transmitting the analog signal of the target frequency band based on the signal scenario file through a signal generator; obtaining the signal strength of the analog signal received by the positioning module; based on the difference between the signal strength corresponding to each target frequency band and the reference signal strength, and the dependency between the target frequency bands in the positioning module, determining the target test standard required for each target frequency band, the target test standard including the target transmission parameters of the analog signal, and the target signal strength of the analog signal received by the positioning module. In this way, multiple frequency bands supported by the positioning module can be quickly tested according to the test standard, thereby improving the test efficiency of multiple frequency bands of the positioning module.
