Referring to fig. 1, a test system 1 provided in an embodiment of the present application is shown. The test system 1 includes: the device comprises a tested terminal 100, a detection device 200 and a test terminal 300, wherein the detection device 200 and the tested terminal 100 are connected with the test terminal 300, and the tested terminal 100 is connected with the detection device 200.
The terminal 100 to be tested can transmit a bluetooth signal, and a bluetooth transmitting device is arranged in the terminal, and the bluetooth transmitting device can transmit the bluetooth signal corresponding to the transmission parameter according to the preset transmission parameter. Specifically, the method and apparatus provided in the embodiment of the present application are applied to a non-signaling test of a bluetooth transmission signal of a terminal under test, and a paired bluetooth connection is established between the terminal under test 100 and the detection device 200 through the test terminal.
In the embodiment of the present application, the terminal 100 under test may be a mobile terminal device, and for example, may include an electronic device capable of transmitting a bluetooth signal, such as a smart phone, a tablet computer, an e-book reader, a laptop portable computer, a vehicle-mounted computer, and a wearable mobile terminal.
The detection device 200 can receive the bluetooth signal transmitted by the terminal 100 under test and can obtain the power value of the bluetooth signal. Specifically, the detection device 200 may be a radio frequency power meter, a radio frequency signal analyzer, or the like having a radio frequency test instrument that receives a bluetooth signal through an antenna and acquires a power value of the received bluetooth signal according to a predetermined algorithm.
The test terminal 300 is configured to instruct the terminal to be tested to transmit a bluetooth signal by sending an instruction to the terminal to be tested, and can obtain a power value of the bluetooth signal transmitted by the terminal to be tested, which is acquired by the detection device, and adjust the power transmitted by the terminal to be tested according to the power value.

Then, the test terminal 300 writes the power compensation parameter into the terminal under test through the data line. And when the tested terminal reads the power compensation parameter, adjusting the transmitted Bluetooth signal according to the power compensation parameter, wherein the specific adjustment mode is described in detail in the following embodiments.
Referring to fig. 2, in particular, fig. 2 shows a bluetooth signal adjusting method provided in the embodiment of the present application, which is applied to the test system shown in fig. 1, and in particular, a process of the method is described with a test terminal as an execution subject of the method, where the method includes: s201 to S205.
S201: and sending a transmitting instruction to the tested terminal to indicate the tested terminal to transmit a Bluetooth signal.
Specifically, the method and the device provided by the embodiment of the application are applied to a non-signaling test of a bluetooth signal of a tested terminal, and under the non-signaling test, the tested terminal controls the establishment of communication connection between the tested terminal and a detection device through data lines such as a USB or other communication modes, specifically, the tested terminal sets a frequency band and a frequency point of the tested terminal, so that the tested terminal and the detection device establish bluetooth communication connection according to the frequency band and the frequency point. The test terminal controls the tested terminal to transmit the Bluetooth signal by inputting the transmitting instruction to the tested terminal, and the detection device serves as a one-way receiver and can acquire the Bluetooth signal transmitted by the test terminal. The transmission instruction can be input into the terminal under test through a data line such as a USB by the test terminal, and the transmission instruction is used to instruct the terminal under test to transmit a bluetooth signal according to the stored transmission parameters, where the transmission parameters are parameters of each circuit element in the bluetooth transmitting apparatus of the terminal under test, such as a radio frequency gain index or a channel quality index.
In addition, before the test terminal sends the transmission instruction, an initialization operation is required, which specifically includes: loading a Bluetooth target power file, detecting the initialization operation of equipment and controlling a tested terminal to enter a non-signaling test mode, wherein the target power file comprises a target power value which is an expected value that the power of a Bluetooth signal emitted by the tested terminal can be expected to reach, and the testing terminal loads the Bluetooth target power file to obtain the target power value. And the initialization operation of the detection device is to clear the power value stored by the detection device and to set the frequency band of the wireless signal that the detection device is capable of receiving, for example, to the frequency band of a bluetooth signal.
S202: and acquiring the power value of the Bluetooth signal transmitted by the terminal to be detected and acquired by the detection equipment.
After the detection equipment is started or initialized, the received Bluetooth signals can be collected in real time, and power analysis such as Fourier change is carried out on the collected Bluetooth signals so as to obtain the power value of the Bluetooth signals. The detection device sends the power value to the test terminal. Specifically, the power value of the bluetooth signal may be sent to the test terminal after the detection device collects the bluetooth signal sent by the terminal to be tested and analyzes the power value of the bluetooth signal. The detection device may collect the bluetooth signal sent by the terminal to be detected, analyze the power value of the bluetooth signal, and store the power value in the local memory. The test terminal sends an acquisition request to the detection equipment, and the detection equipment sends the power value of the Bluetooth signal to the test terminal after receiving the acquisition request.
S203: and judging whether the power value meets a preset compensation condition.
The preset compensation condition is set according to the expected target power value of the Bluetooth signal of the tested terminal and the power range which the Bluetooth signal of the tested terminal is supposed to reach under the condition of meeting the normal use requirement. Specifically, the manner of determining whether the power value satisfies the preset compensation condition is as follows:
judging whether the power value meets a preset qualified standard or not; if the power value meets the preset qualified standard, judging whether the power difference value between the power value and a preset target power value is within a preset compensation range; and if the power value is within the preset compensation range, judging that the power value meets the preset compensation condition.
Specifically, the preset qualified standard is used for detecting whether the power value of the bluetooth signal transmitted by the device to be tested reaches the qualified standard, and if the power value does not meet the preset qualified standard, the device to be tested is determined to be an unqualified product, and power compensation adjustment of the device to be tested is not needed. If the power value meets the preset qualified standard, the tested terminal is a qualified product, the power of the transmitted Bluetooth signal can meet the requirement of normal use, and the operation of judging whether the power difference value between the power value and the pre-acquired target power value is within the preset compensation range is continuously executed. The predetermined qualified criterion may be set according to a requirement of the transmission power of the bluetooth signal of the terminal under test in actual use, for example, the predetermined qualified criterion is greater than a first power value and less than a second power value, i.e., a range between the first power value and the second power value, where the first power value is a target power value plus a, and the second power value is the target power value minus a, where a may be 2mW, and the first power value is greater than the second power value. It is determined whether the power value is within a range between the first power value and the second power value, and if so, it is determined that the power value satisfies a preset qualification criterion, and if the power value is outside the range between the first power value and the second power value, it is determined that the power value does not satisfy the preset qualification criterion.
And under the condition that the power value meets a preset qualified standard, judging whether the power difference value between the power value and a pre-acquired target power value is within a preset compensation range. The preset compensation range is a criterion for judging whether the transmission power of the bluetooth signal of the terminal to be tested needs to be adjusted. Specifically, the predetermined compensation range is greater than a third power value or less than a fourth power value, the third power value being greater than the fourth power value, for example, the third power value is +0.5mW, and the fourth power value is-0.5 mW. And if the power difference value between the power value and the pre-acquired target power value is within the range between the third power value and the fourth power value, determining that the power difference value is not within the preset compensation range, and if the power difference value is smaller than the fourth power value or larger than the third power value, determining that the power difference value is within the preset compensation range. That is to say, if the absolute value of the power difference is less than 0.5mW, it is determined that the power difference is not within the preset compensation range, that is, the current power value has satisfied the standard, and it is not necessary to adjust the transmission power of the bluetooth signal of the terminal under test, if the absolute value of the power difference is greater than 0.5mW and less than 2mW, it is determined that the power difference is within the preset compensation range, and it is necessary to adjust the transmission power of the bluetooth signal of the terminal under test, so that the power of the bluetooth signal transmitted by the terminal under test can be closer to the target power value.
It should be noted that, in some embodiments, when the power value is determined to meet the preset qualified standard, step S204 may be directly performed, that is, whether the power difference between the power value and the pre-obtained target power value is within the preset compensation range or not, the transmission power of the bluetooth signal of the terminal under test may be adjusted according to the power difference.
S204: and acquiring a power difference value between the power value and a pre-acquired target power value.
And acquiring a power difference value between the power value and a pre-acquired target power value when the power value is judged to meet a preset compensation condition. The target power value is set according to the requirement of the transmission power of the Bluetooth signal of the tested terminal in actual use.
S205: and acquiring a power compensation parameter according to the power difference, writing the power compensation parameter into the tested terminal, and indicating the tested terminal to adjust the transmitted Bluetooth signal according to the power compensation parameter when reading the power compensation parameter.
And converting the power difference value into a power compensation parameter which can be identified by the tested terminal, specifically, converting the power difference value into the power compensation parameter according to the electrical parameter of the Bluetooth transmitting device of the tested terminal which is acquired in advance. The electrical parameter of the bluetooth transmitting apparatus of the terminal to be tested includes a data format that can be recognized by the bluetooth transmitting apparatus of the terminal to be tested, and specifically, may be a format standard of an interface of a chip of the bluetooth transmitting apparatus for received data. For example, the format standard of the data received by the MTK or high-pass chip to its interface is different, for example, the requirement of high-pass is that the data must be a number greater than a certain value, for example, the power difference is-1, then the conversion mode may be-1 × 10+100 to obtain 90, and the obtained power compensation parameter is 90.
And then, writing the power compensation parameter into the tested terminal, instructing the tested terminal to adjust the transmission parameter of the Bluetooth transmitting device according to the power compensation parameter when reading the power compensation parameter, and transmitting a Bluetooth signal according to the adjusted transmission parameter. The transmission power of the bluetooth signal transmitted by the tested terminal is related to the transmission parameter of the bluetooth transmitting device, wherein the transmission parameter can be a radio frequency gain index or a channel quality index, and the like, and a compensation algorithm is arranged in the tested terminal, and the transmission parameter can be adjusted by utilizing the power compensation parameter according to the compensation algorithm, so that the transmitted bluetooth signal is adjusted.
It should be noted that, after the test terminal writes the power compensation parameter into the tested terminal, the tested terminal stores the power compensation parameter, when the bluetooth signal is transmitted, it is read first whether the power compensation parameter is stored, and if the power compensation parameter can be read, the transmitted bluetooth signal is adjusted according to the power compensation parameter.
In some embodiments, the power compensation parameter is set reasonably, so that the terminal to be tested can directly adjust the transmitted bluetooth signal to be close to the target power value according to the power compensation parameter obtained this time, that is, within the preset compensation range, that is, no readjustment is needed.
In other embodiments, after the power compensation parameter is written into the terminal to be tested, the terminal to be tested is controlled to transmit the bluetooth signal again, and whether the power value meets the preset compensation condition is determined again, and multiple iterations are performed to make the power value transmitted by the terminal to be tested continuously approach the target power value, i.e. under the condition that the power value meets the preset qualified condition, the power difference value can be located outside the preset compensation range finally, and power adjustment is not needed any more.
Specifically, referring to fig. 3, fig. 3 shows a bluetooth signal adjustment method provided in the embodiment of the present application, which is applied to the test system shown in fig. 1, and specifically, a process of the method is described with a test terminal as an execution subject of the method, where the method includes: s301 to S311.
S301: and sending a transmitting instruction to the tested terminal to indicate the tested terminal to transmit a Bluetooth signal.
S302: and acquiring the power value of the Bluetooth signal transmitted by the terminal to be detected and acquired by the detection equipment.
S303: and judging whether the power value meets a preset qualified standard.
S304: and judging whether the power difference value between the power value and the pre-acquired target power value is within a preset compensation range.
S305: and judging whether the power difference value obtained last time is stored.
The power difference value obtained by the test terminal every time is correspondingly stored in the history obtaining record, and whether the power difference value obtained this time is obtained for the first time is judged according to the history obtaining record, namely whether the power difference value obtained last time is stored is judged.
S306: and summing the power difference obtained last time and the power difference obtained this time to obtain an accumulated power difference.
When it is determined that the power difference value acquired last time is not acquired for the first time, that is, it is determined that the power difference value acquired last time is stored, the power difference value acquired last time and the power difference value acquired this time are summed to obtain an accumulated power difference value. For example, if the stored power difference value obtained last time is a and the power difference value obtained this time is B, the accumulated power difference value is a + B.
S307: and taking the accumulated power difference value as the power difference value obtained at this time and storing the power difference value.
The accumulated power difference, for example, a + B described above, is used as the power difference acquired this time and is stored in the corresponding history acquisition record.
Specifically, the following table is stored:
reference numerals Obtained by After accumulation Stored
1 A A A
2 B A+B A+B
3 C A+B+C A+B+C
Where the reference numeral is used to indicate the number of times, for example, reference numeral 1 indicates the power difference value obtained for the first time, and reference numeral 3 indicates the power difference value obtained for the third time, then the value in the column of "stored" is recorded as the corresponding stored power difference value for the time, for example, the power difference value stored for the first time is a, and the power difference value stored for the third time is a + B + C. According to the table, whether the power difference value is stored before the current time can be judged, and the power difference value stored before can be obtained.
S308: and converting the power difference value into a power compensation parameter according to the electric parameter of the Bluetooth transmitting device of the tested terminal, which is acquired in advance.
S309: and sending the power compensation parameter to the tested terminal, indicating the tested terminal to adjust the transmission parameter of the Bluetooth transmitting device according to the power compensation parameter when reading the power compensation parameter, and transmitting a Bluetooth signal according to the adjusted transmission parameter.
S310: and clearing the power compensation parameters stored in the tested terminal.
And under the condition that the judgment power value does not meet the preset qualified standard, judging that the tested terminal is unqualified, and returning the tested terminal to the calibration link to perform calibration operation again. The power compensation parameters stored in the terminal under test are deleted, where the power compensation parameters input by the calibration step are stored in the terminal under test, and also include the power compensation parameters written in the process of adjusting the bluetooth signal of the terminal under test, and these power compensation parameters are the reasons that the power value does not meet the preset qualified standard, so that it is necessary to return to the calibration step after clearing all the power compensation parameters, that is, S311 is executed.
S311: and executing recalibration operation to write a preset initial power compensation parameter into the tested terminal, wherein the preset initial power compensation parameter is used for adjusting the power parameter of the Bluetooth signal transmitted by the tested terminal to meet a preset qualified standard.
Wherein the initial power compensation parameter is preset, i.e. the inherent power compensation parameter input in the calibration operation. The calibration operation is to calibrate certain specific frequency points of the Bluetooth transmitting signals of the tested terminal in the production process of the tested terminal, then generate certain preset initial power compensation parameters through certain algorithms and temperature compensation algorithms, and write the preset initial power compensation parameters into the tested terminal. However, in the calibration operation, the calibration is inaccurate due to the contact of the thimble or the influence of inaccurate temperature or line loss compensation of a production line or the difference of the algorithm, so that the power value of the bluetooth signal actually transmitted by the terminal to be tested cannot meet the preset qualified standard.
Therefore, in the case that the power value is judged not to satisfy the preset qualified standard, the calibration operation is executed again, namely, the power compensation parameters causing the power value not to satisfy the preset qualified standard are deleted, and the preset initial power compensation parameters are input again, so as to adjust the power value of the bluetooth signal transmitted by the tested terminal to satisfy the preset qualified standard, wherein the newly input preset initial power compensation parameters are generated in the calibration operation, and the algorithm in the calibration operation is adjusted to input new preset initial power compensation parameters again so as to enable the power value of the bluetooth signal transmitted by the tested terminal to satisfy the preset qualified standard in the case that the transmission power of the bluetooth signal of the tested terminal does not satisfy the preset qualified standard based on the previously input preset initial power compensation.
It should be noted that, after the preset initial power compensation parameter is written in, it may be determined again whether the power value of the bluetooth signal transmitted by the terminal to be tested meets the preset qualified standard, and if the power value of the bluetooth signal transmitted by the terminal to be tested is still unqualified, the power compensation parameter stored in the terminal to be tested is cleared again, and the recalibration operation is performed again until the power value of the bluetooth signal transmitted by the terminal to be tested meets the preset qualified standard. Further, the number of times of executing the recalibration operation is recorded, and when the number of times is equal to a preset upper limit value, the power compensation parameter stored in the tested terminal is not cleared and the recalibration operation is not executed any more, and the tested terminal is judged to be a defective product and is discarded.
It should be noted that, for the parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not described herein again.
In addition, considering that, when a plurality of iterations are performed to make a difference between a power value of a bluetooth signal transmitted by a terminal under test and a target power value meet a requirement, that is, the power value meets a preset qualification standard, and a power difference between the power value and a target power value obtained in advance is outside a preset compensation range, if the number of iterations is too large, a stress is imposed on a test system, a test resource is excessively occupied, and a cost is excessively increased, so that a limitation needs to be imposed on the number of iterations, specifically, referring to fig. 4, fig. 4 shows a bluetooth signal adjustment method provided by an embodiment of the present application, which is applied to the test system shown in fig. 1, and specifically, a process of the method is described by taking a test terminal as an execution subject of the method, the method includes: s401 to S413.
S401: and sending a transmitting instruction to the tested terminal to indicate the tested terminal to transmit a Bluetooth signal.
S402: and acquiring the power value of the Bluetooth signal transmitted by the terminal to be detected and acquired by the detection equipment.
S403: and judging whether the power value meets a preset qualified standard.
