[0062] The foregoing embodiments are described in detail below.

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

[0064] The application provides a test standard determination method, which comprises the following steps: determining signal scenario files corresponding to at least two target frequency bands required to be tested by a positioning module; transmitting analog signals of the target frequency bands based on the signal scenario files by a signal generator; acquiring signal strengths of the analog signals received by the positioning module; determining target test standards required by the target frequency bands based on differences between the signal strengths corresponding to the target frequency bands and reference signal strengths and a dependency relationship between the target frequency bands in the positioning module, wherein the target test standards comprise target transmission parameters of the analog signals and target signal strengths of the analog signals received by the positioning module.

[0065] Please refer to Figure 2 An embodiment flowchart of the test standard determination method in the embodiments of the application is shown in the figure, and the test standard determination method comprises the following steps:

[0066] 101. Determine signal scenario files corresponding to at least two target frequency bands required to be tested by a positioning module.

[0067] In the embodiments of the application, the positioning module can comprise a GNSS module, which is usually composed of a GNSS receiver, an antenna, a processor, a memory and other components. The GNSS module calculates the position of the device by receiving signals from multiple satellite navigation systems such as the global positioning system (GPS), Galileo satellite navigation system, GLONASS system and Beidou navigation system, and using the principle of triangulation. After receiving the signals, the processor in the module will solve the signals and calculate the longitude, latitude, altitude and other position information of the device, and then transmit these information to the application program for further processing.

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

[0069] For example, the frequency bands can include L1, L2 and L5, 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, and the center frequency of the L5 frequency band is 1176.45 MHz.

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

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

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

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

[0074] In some embodiments, the simulated signals can be generated by a signal simulator, which can simulate the signals emitted by different satellite navigation systems on different frequency bands.

[0075] For example, the frequency bands can include L1, L2, and L5 frequency bands. The signal simulator can simulate the signals emitted on the L1 frequency band to obtain the simulated signals corresponding to the L1 frequency band and store them in the signal scenario file 1. The signal simulator can simulate the signals emitted on the L2 frequency band to obtain the simulated signals corresponding to the L2 frequency band and store them in the signal scenario file 2. The signal simulator can simulate the signals emitted on the L5 frequency band to obtain the simulated signals corresponding to the L5 frequency band and store them in the signal scenario file 5. Thus, multiple signal scenario files can be obtained, each of which stores simulated signals corresponding to different frequency bands.

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

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

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

[0079] From the multiple candidate signal scenario files, determining the signal scenario file corresponding to the target frequency band.

[0080] The product attribute information can include support frequency band information of the positioning module, that is, frequency bands supported by the positioning module, such as supporting L1 frequency band and L2 frequency band.

[0081] The product attribute information of the positioning module can 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 application, after obtaining the product attribute information, the frequency bands supported by the positioning module included in the attribute information can be used as target frequency bands to be tested by the positioning module.

[0083] For example, if the frequency bands supported by the positioning module include L1 frequency band and L2 frequency band, the L1 frequency band and the L2 frequency band can be used as target frequency bands to be tested by the positioning module.

[0084] In some embodiments, the product attribute information can further include other information, such as data transmission protocol, working state, etc. Other function items to be tested by the positioning module can be determined according to the information, and the other functions can be tested.

[0085] 102. Emitting, by the signal generator, the analog signal of the target frequency band based on the signal scenario file.

[0086] The signal generator is a device that can provide various frequency, waveform and output level electrical signals, also known as signal source or oscillator. The principle of the signal generator is mainly to generate a low-frequency sinusoidal oscillation signal through the main oscillator stage. This signal is amplified by the voltage amplifier to meet the voltage output amplitude requirement. Then, the signal can be directly output through the output attenuator, and the main oscillator output adjustment potentiometer can be used to adjust the size of the output voltage. This principle enables the signal generator to generate stable and adjustable electrical signals.

[0087] The signal generator can be connected, the signal scenario file can be sent to the signal generator to control the signal generator to send the analog signal (that is, the analog signal corresponding to the target frequency band) in the signal scenario file.

[0088] In some embodiments, when the signal generator emits the analog signal, the emission parameters of the signal generator can be configured, such as emission power, etc. The emission power of the signal refers to the energy intensity of the radio transmitter radiated in the form of electromagnetic waves through the antenna in a given frequency band. It is an important parameter for measuring the signal transmission capability of the wireless device, which directly affects the transmission distance, penetration ability and reception quality of the signal. The size of the emission power determines the strength and coverage range of the radio signal, and is one of the important indicators for evaluating the performance of the wireless device.

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

[0090] For example, the target frequency bands can include an L1 frequency band and an L2 frequency band. The signal generator can be sent a signal scenario file 1 corresponding to the L1 frequency band and a signal scenario file 2 corresponding to the L2 frequency band, and then controlled to transmit an analog signal 1 in the signal scenario file 1 and an 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] The positioning module can analyze the analog signal after receiving the analog signal, thereby determining the signal strength of the received analog signal, obtaining signal information, and then sending the signal information to the server. The signal information can include frequency bands, signal strengths, and the like. 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 send signal information 1 to the server. The signal information 1 includes: the signal strength of the received analog signal 1 of the L1 frequency band is n.

[0094] 104. Determine the target test standard required by 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 relationship between the target frequency bands in the positioning module.

[0095] In the positioning module, the dependency relationship between the frequency bands mainly reflects how they work together to improve the positioning accuracy, stability, and anti-interference ability.

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

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

[0098] The reference signal strength refers to the signal strength of the analog signal expected to be received by the receiving end for each frequency band. Different frequency bands can have different reference signal strengths.

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

[0100] In some embodiments, in order to determine the test standards according to different dependency relationships of the target frequency bands, the step of "determining the target test standards required by the target frequency bands based on the differences between the signal strengths corresponding to the target frequency bands and the reference signal strengths and the dependency relationships between the target frequency bands in the positioning module" can include the following operations:

[0101] determining a first target frequency band in which there is no dependency relationship in the 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 a first target transmission parameter based on the transmission power of the signal generator and determining a first target signal strength based on the reference signal strength;

[0103] obtaining a first target test standard corresponding to the first target frequency band based on the first target transmission parameter and the first target signal strength.

[0104] The first target frequency band refers to a target frequency band in which there is no dependency relationship in the target frequency bands required to be tested by the positioning module.

[0105] Specifically, whether there is a signal strength difference requirement can be determined to determine whether there is a dependency between the target frequency bands. The target frequency band in which there is no signal strength difference requirement can be used as the first target frequency band.

[0106] In the embodiments of the present application, for the first target frequency band in which there is no dependency relationship, the target test standards corresponding to the first target frequency bands can be respectively determined according to the signal strengths corresponding to the first target frequency bands and the reference signal strengths, that is, the first target test standards.

[0107] Specifically, for each first target frequency band, the target test standard thereof can be determined in the following manner:

[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 according to 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] The first target signal strength can be determined based on the reference signal strength and a preset value. The signal strength range can be determined according to the reference signal strength and the preset value. The signal strength range can be used as the first target signal strength.

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

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

[0112] For example, the transmission power of the current signal generator can be n, and the first target signal strength can be 41-45DB. The first target test standard of the first target frequency band can be obtained, that is, the transmission power of the signal generator is n, and the signal strength of the received signal of the positioning module is 41-45DB. 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 can be calibrated. The method can further include the following steps:

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

[0115] The transmission power value of the signal generator is adjusted based on the first difference value to obtain a target transmission power value.

[0116] The signal generator transmits the analog signal of the first target frequency band based on the target transmission power until the signal strength of the received analog signal of the positioning module is the same as the reference signal strength. The first target test standard corresponding to the first target frequency band is obtained based on the target transmission power and the reference signal strength.

[0117] The first difference value represents the difference between the signal strength of the received analog signal of 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 is calculated to obtain the first difference value.

[0119] Wherein, the adjusting the transmission power value of the signal generator according to the first difference value can include increasing or decreasing the transmission power value. If the first difference value is greater than 0, it means that the signal strength is greater than the reference signal strength, and further the transmission power of the signal generator can be decreased, so as to decrease 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 value is less than 0, it means that the signal strength is less than the reference signal strength, and further the transmission power of the signal generator can be increased, so as to increase 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 value between the signal strength corresponding to the first target frequency band and the reference signal strength corresponding to the first target frequency band can be 2DB, and the transmission power of the signal generator can be increased by 2DB to obtain the target transmission power value.

[0121] Further, 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 adjustment, and the signal strength of the analog signal received by the positioning module is continued to be acquired, and the signal strength and the reference signal strength are compared again to determine whether the signal strength and the reference signal strength are the same. If not, the transmission power of the signal generator can be continued to be adjusted according to the difference value 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 last adjusted transmission power can be taken 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 taken as the first target test standard of the first target frequency band.

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

[0123] If the number of times of adjusting the transmission power value of the signal generator exceeds the preset number of times, the 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] Wherein, the number of times of adjusting the transmission power value of the signal generator refers to the number of times of adjusting the transmission power of the signal generator when the signal strength of the analog signal of the first target frequency band received by the positioning module does not meet the reference signal strength.

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

[0126] The calibration failure information indicates that the transmission power of the signal generator is still unable to make the signal strength satisfy the reference signal strength in the calibration test of the analog signal of the first target frequency band. The calibration failure information can be fed back to the tester to make the tester confirm the failure reason.

[0127] For example, refer to Figure 3 , Figure 3 is a calibration process schematic diagram of the test standard determination method provided in the embodiments of the present application. Figure 3 The calibration process of the test standard of the positioning module is shown, which can be specifically as follows:

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

[0129] The product configuration information of the positioning module is acquired, and the test frequency band information of the positioning module is determined according to the product configuration information. The test frequency band information can include the target frequency band supported by the positioning module;

[0130] According to the target frequency band in the test frequency band information, the signal scene file corresponding to each target frequency band is acquired. The signal scene file includes the analog signal corresponding to the target frequency band;

[0131] The signal generator is connected and detected to determine whether the connection of the signal generator is normal;

[0132] If the connection of the signal generator is abnormal, it is determined that the calibration fails, and then the calibration failure information is generated and fed back to the tester, so that the tester checks the signal generator and triggers the calibration process again;

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

[0134] It is determined whether the calibration times reach the preset times. The calibration times can indicate the number of times of calibrating the transmission power of the signal generator;

[0135] If the calibration times reach the preset times, it is determined that the calibration fails, and then the calibration failure information is generated and fed back to the tester, so that the tester checks according to the calibration failure information and triggers the calibration process again;

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

[0137] The fixture for fixing the positioning module is connected to the power supply, the positioning module is powered on, the positioning module is controlled to enter the working state, and the analog signal is received;

[0138] The signal strength of the analog signal received by the positioning module is acquired, and it is determined whether the signal strength reaches a 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, and it is indicated that the calibration is successful. Then, the test personnel can be fed back the information that the calibration is successful, so that the test personnel records the test standard for subsequent testing of the positioning module. Thus, the calibration process ends, and the various connections 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. Then, the process returns to the step of determining whether the calibration times reach the preset times.

[0141] In some embodiments, in order to determine the test standard according to the different dependency relationships of the target frequency bands, the step of determining the target test standard required by 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 relationship between the target frequency bands in the positioning module can include the following operations:

[0142] At least one group of target frequency bands having a dependency relationship in at least two target frequency bands is determined.

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

[0144] The second target test standard corresponding to the second target frequency band is obtained based on the second target transmission parameter and the second target signal strength.

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

[0146] Each group of target frequency bands refers to a plurality of target frequency bands having a dependency relationship in the target frequency bands required to be tested by the positioning module. Each group of target frequency bands includes a second target frequency band that is dependent and a third target frequency band that depends 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 can include that the difference between the signal strength of the analog signal received by the positioning module for the second target frequency band and the signal strength of the analog signal received for the third target frequency band meets a preset difference.

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

[0149] In the embodiments of the present application, for a group of target frequency bands with a dependency relationship, the second target test standard corresponding to the second target frequency band in each group of target frequency bands can be determined according to the signal strength corresponding to the second target frequency band and the reference signal strength. Further, the third target test standard corresponding to the third target frequency band can be determined according to the second target test standard and based on the signal strength difference requirement between the second target frequency band and the third target frequency band.

[0150] Specifically, for each second target frequency band, the target test standard thereof can be determined in the following manner:

[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 taken 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 taken as the second target test standard corresponding to the second target frequency band.

[0152] The second target signal strength can be determined based on the reference signal strength, which can include determining two signal strength ranges according to the reference signal strength and a preset value, and taking the signal strength in the signal strength range as the second target signal strength.

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

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

[0155] The difference between the signal strength corresponding to the third target frequency band and the signal strength corresponding to the second target frequency band is calculated to obtain a second difference value;

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

[0157] The signal strength corresponding to the third target frequency band refers to a signal strength of an analog signal received by the positioning module at the third target frequency band; and the signal strength corresponding to the second target frequency band refers to a signal strength of an analog signal received by the positioning module at the second target frequency band.

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

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

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

[0161] In the embodiments of the present application, if the second difference does not satisfy the reference difference, the operation needs to be ended, and the tester needs to be informed to overhaul and confirm, that is, signal strength abnormal information of the second target frequency band and the third target frequency band can be generated, and the signal strength abnormal information is fed back to the tester, so that the tester analyzes the positioning module and the signal generator according to the signal strength abnormal information.

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

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

[0164] Based on the second target transmission parameter and the adjusted target signal strength, a third target test standard is determined.

[0165] The second difference satisfying the reference difference can include that the second difference is equal to the reference difference.

[0166] In the embodiments 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 an adjusted target signal strength, and then the third target test standard corresponding to the third target frequency band can be obtained according to the second target transmission parameter and the adjusted target signal strength.

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

[0168] For example, the second target signal strength can include 39-44DB, the reference difference can be 2DB, 39-2 and 44-2 can be calculated, and the adjusted target signal strength is 37-42DB.

[0169] In some embodiments, in order to obtain accurate test standards, for the second target frequency band and the third target frequency band with a dependency relationship, if the test standard of the second target frequency band is abnormal in the calibration process, the test standard of the third target frequency band does not need to be determined continuously, the reason why the test standard of the second target frequency band is abnormal in the calibration process can be analyzed, the calibration process of the test standard of the second target frequency band is re-executed, and after the test standard of the second target frequency band is successfully determined, the test standard of the third target frequency band can be determined according to the test standard of the second frequency band. In this way, the test standards corresponding to the target frequency bands can be obtained.

[0170] Further, after the test standards of the target frequency bands are determined, the target frequency bands of the positioning module can be quickly tested according to the test standards, and test results are obtained, so that the test efficiency of the positioning module can be improved.

[0171] The embodiment discloses a test standard determination method, including: determining signal scene files corresponding to at least two target frequency bands that need to be tested by a positioning module; emitting analog signals of the target frequency bands based on the signal scene files by a signal generator; obtaining signal strengths of the analog signals received by the positioning module; determining target test standards required by the target frequency bands based on differences between signal strengths corresponding to the target frequency bands and reference signal strengths, and a dependency relationship between the target frequency bands in the positioning module, the target test standards including target transmission parameters of the analog signals and target signal strengths of the analog signals received by the positioning module. In this way, multiple frequency bands supported by the positioning module can be quickly tested according to the test standards, and the test efficiency of the multiple frequency bands of the positioning module can be improved.
