Detailed ways

The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Referring to FIG. 1 , FIG. 1 is a flow chart of a first embodiment of a radio frequency device detection method provided by the present application, which is applied to a radio frequency module. The radio frequency module includes a plurality of paths, each path includes a plurality of radio frequency devices, and the radio frequency device detection method includes:

Step 11: Test the target path to obtain a test loss value; and calibrate based on the test loss value to obtain a calibration loss value corresponding to the target path.

In some embodiments, the RF module to be tested is connected to the detection terminal, the RF module to be tested includes several paths, each path includes several RF devices, and the detection terminal can be used to send instructions to the RF module to be tested, power on the RF module to be tested, and write the parameters in the initialization file into the memory of the RF module to be tested, and then use the parameters in the initialization file (such as the initialization file) to test the RF module to be tested, and obtain the test results, wherein the test results include the test loss value. Wherein, the RF module can be a printed circuit board.

In some embodiments, after the RF circuit board to be tested is connected to the port of the detection terminal, the detection terminal can be used to power on the RF circuit board to be tested, and the corresponding test software on the detection terminal can be used to issue instructions to the RF circuit board to be tested, and the parameters in the initialization file are written into the RAM (Random Access Memory) in the RF circuit board to be tested, and then each RF path is tested to obtain the test loss value. Among them, the detection terminal can be a comprehensive tester.

In some embodiments, a calibration loss value corresponding to the target path is obtained by acquiring a parameter calibration range corresponding to the target path and then calibrating the test loss value using parameters within the parameter calibration range.

The parameters within the parameter calibration range are the insertion loss values of each RF device in the path.

Specifically, after testing the target path, the parameter calibration range of the target path can be obtained from a configuration file (such as a configure file) to calibrate the test loss value using the parameters within the parameter calibration range to obtain the calibration loss value corresponding to the target path. The calibration loss value can be represented by RX_path_loss.

In some embodiments, after obtaining the calibration loss value, the calibration loss value may be compared with a preset loss range of the corresponding target path to determine whether the calibration loss value exceeds the preset loss range of the corresponding target path.

Among them, the preset loss range is the loss threshold range from each RF device to the antenna port of the RF module or the RF chip, which can be expressed as [LL _nm , HL _nm ], where LL represents Low Limit, HL represents High Limit, the RF path in the RF module is identified by n (n is a positive integer greater than or equal to 1, that is, n∈N*), and the RF device in the RF path is identified by m (m is a positive integer greater than or equal to 1, that is, m∈N*), that is, n represents the path to which the RF device belongs, and m represents that the RF device is the mth RF device on a certain path. For example, nm is 12, which means the second RF device on the first path, and nm is 24, which means the fourth RF device on the second path. In addition, the identification order of the RF devices on each path can be determined according to the actual situation, and the path can be a receiving path or a transmitting path.

Specifically, RX_path_loss is compared with [LL _nm , HL _nm ] to determine whether RX_path_loss is within [LL _nm , HL _nm ], and if not, step 12 is executed.

Step 12: In response to the calibration loss value exceeding the preset loss range corresponding to the target path, compare the test loss value with the preset loss range.

It can be understood that if the calibration loss value exceeds the preset loss range of the corresponding target path, it indicates that there is an abnormal RF device in the target path, and further operation is required to confirm the abnormal RF device on the target path. Among them, the reason for the abnormal RF device may be that the RF device is defective or poorly soldered in the RF module.

In some embodiments, when the calibration loss value exceeds the preset loss range of the corresponding target path, the test loss value is compared with the preset loss range to complete one step of confirming the abnormal RF device, and then step 13 is executed.

In other embodiments, in response to the calibration loss value not exceeding the preset loss range of the corresponding target path, the test loss values of the remaining paths are calibrated to obtain the calibration loss values corresponding to the remaining paths. If the calibration loss values corresponding to the remaining paths exceed the preset loss range of the corresponding paths, step 12 and subsequent steps can be performed to determine the abnormal RF device.

Step 13: Associating the test loss value exceeding the preset loss range with the corresponding target RF device identifier, and treating the target RF device corresponding to the target RF device identifier as an abnormal RF device to be determined.

In some embodiments, the test loss value exceeding the preset loss range is associated with the corresponding target RF device identification, and the associated related information is stored as a test log, and the target RF device corresponding to the target RF device identification is treated as an abnormal pending RF device.

Among them, the test log is a log file; the target RF device identifier is nm; the test loss value is associated with the corresponding target RF device identifier, and the obtained associated information can be represented by RX_path_loss_nm to indicate that the mth RF device of the nth path is abnormal.

After obtaining RX_path_loss_nm, RX_path_loss_nm can be uploaded to a log file for storage, and the target RF device corresponding to RX_path_loss_nm can be used as an abnormal RF device to be determined.

Step 14: In response to the error between the calibration loss value and the preset path loss value exceeding the preset error range, the target RF device is regarded as an abnormal RF device and is located according to the target RF device identifier.

Each RF device is set with a preset path loss value, which can be represented by RX_path_loss1; the preset error range can be represented by △n, and the range of △n can be set according to actual conditions, such as [-0.1, 0.1]; the error between the calibration loss value and the preset path loss value can be represented by δ.

Specifically, if δ exceeds △n, the target RF device can be regarded as an abnormal RF device. Since the target RF device identifier nm includes the specific position of the target RF device, the target RF device can be located according to the target RF device identifier.

Different from the prior art, the RF device detection method provided by the present application tests the target path to obtain a test loss value, and calibrates based on the test loss value to obtain a calibration loss value corresponding to the target path; in response to the calibration loss value exceeding the preset loss range of the corresponding target path, the test loss value is compared with the preset loss range; the test loss value exceeding the preset loss range is associated with the corresponding target RF device identifier, and the target RF device corresponding to the target RF device identifier is regarded as an abnormal pending RF device; in response to the error between the calibration loss value and the preset path loss value exceeding the preset error range, the target RF device is regarded as an abnormal RF device and located according to the target RF device identifier. In the above manner, the abnormal RF devices on the path can be detected and synchronously located according to the loss value, which can save time instead of checking one by one.

Step 21: Determine the expected loss range for each channel based on the channel budget and the data sheet of each RF device.

It is understandable that the preset path loss of each path can be determined based on the path budget/link budget of the path to which the RF device belongs and the data sheet of the RF device. The preset loss range is the loss threshold range from each RF device to the antenna port of the RF module or the RF chip.

Step 22: Write the preset loss range to the configuration file.

The configuration file is a configure file. The preset loss range can be written into the configure file to configure the RF device.

Step 23: Test the target path to obtain a test loss value; and calibrate based on the test loss value to obtain a calibration loss value corresponding to the target path.

Step 24: In response to the calibration loss value exceeding the preset loss range corresponding to the target path, compare the test loss value with the preset loss range.

Step 25: Associating the test loss value exceeding the preset loss range with the corresponding target RF device identifier, and treating the target RF device corresponding to the target RF device identifier as an abnormal RF device to be determined.

Step 26: In response to the error between the calibration loss value and the preset path loss value exceeding the preset error range, the target RF device is regarded as an abnormal RF device and is located according to the target RF device identifier.
