The communication module of the present invention can be applied to electronic devices such as notebooks, tablet computers, mobile phones, and wearable devices that require communication functions, which are not specifically limited herein.

The communication module abnormality detection method in this embodiment includes:

Step S101: acquiring the radio frequency signal transmitted by the radio frequency output terminal, and calculating an analog-to-digital conversion ADC value according to the radio frequency signal;

Step S102: Obtain a preset analog-to-digital conversion ADC value range corresponding to a working mode of the communication module, wherein the working mode includes a wireless transmission standard protocol and a transmission rate;

The method for detecting abnormality of a communication module in this embodiment will be described in detail below with reference to FIG. 1 . In the following description, a Wi-Fi communication module will be used as an example for description, and it can be understood that the method for detecting abnormality of a communication module can also be applied to other types of communication modules. The Wi-Fi communication module cannot be used to limit the scope of application of the present invention.

In step S101, when starting to detect the Wi-Fi communication module, the external device will send an instruction to the Wi-Fi communication module, so that the Wi-Fi communication module transmits a radio frequency signal with a corresponding power according to the instruction. Specifically, the radio frequency output end of the Wi-Fi chip will transmit radio frequency signals of corresponding power. The radio frequency signal is passed to the detector through the coupler. Here, the coupler can completely couple the radio frequency signal, or can couple a part of the power radio frequency signal according to a certain ratio, which is not specifically limited here.

After the detector receives the radio frequency signal coupled by the coupler, it will perform detection processing on the radio frequency signal, convert the high frequency radio frequency signal into a low frequency baseband signal, and transmit the low frequency baseband signal to the analog-to-digital converter, wherein The low-frequency baseband signal is an analog signal.

After receiving the low-frequency baseband signal, the analog-to-digital converter converts the analog baseband signal into a corresponding digital signal. At the same time, the analog-to-digital conversion ADC value corresponding to the digital signal is calculated, that is, the analog-to-digital conversion ADC value corresponding to the radio frequency signal output by the radio frequency output terminal of the Wi-Fi chip is calculated. It can be understood that the analog-to-digital conversion ADC value is a value output by an analog-to-digital converter (Analog to Digital Converter, ADC for short).

In step S102, after the analog-to-digital converter calculates the analog-to-digital converted ADC value, the analog-to-digital converted ADC value is transmitted to the processing chip in the communication device. At the same time, the processing chip will acquire the preset analog-to-digital conversion ADC value range corresponding to the working mode of the Wi-Fi communication module. It should be noted here that the working mode of the Wi-Fi communication module includes wireless transmission standard protocols and transmission rates. For example, the Wi-Fi communication module adopts the wireless transmission standard protocol of 802.11g and the working mode of the transmission rate of 54Mb/s.

Because the preset analog-to-digital conversion ADC value range of the Wi-Fi communication module is different when it is in different working modes, the preset analog-to-digital conversion ADC value range corresponding to each working mode of the Wi-Fi communication module is stored in the memory of the communication device. Digital conversion ADC value range. After the processing chip obtains the analog-to-digital conversion ADC value, it first obtains the current working mode of the Wi-Fi communication module, and then reads the corresponding preset analog-to-digital conversion ADC value from the memory according to the current working mode of the Wi-Fi communication module. scope. It should be noted that, there is no clear sequence between step S101 and step S102, and step S102 may be performed first, and then step S101 may be performed, which is not specifically limited here.

In steps S103 and S104, the processing chip will determine whether the analog-to-digital conversion ADC value is within the preset analog-to-digital conversion ADC value range. If the processing chip determines that the analog-to-digital conversion ADC value is within the preset analog-to-digital conversion ADC value range, it indicates the power value of the radio frequency signal transmitted by the Wi-Fi chip and the specified power value in the command sent by the external device. Basically the same, that is, the Wi-Fi communication module is in a normal state in the current working mode, and the technician can detect the next working mode or the next test item at this time.

If the processing chip determines that the analog-to-digital conversion ADC value is not within the preset analog-to-digital conversion ADC value range, it indicates the power value of the radio frequency signal transmitted by the Wi-Fi chip and the specified power value in the command sent by the external device. The size deviation is very large, that is, the Wi-Fi communication module is in an abnormal state in the current working mode. At this time, the communication device will send out abnormal prompt information, so that the tester can use the abnormal prompt information to the abnormal cause in the working mode. Analyze and judge.

In the method for detecting abnormality of a communication module in this embodiment, an analog-to-digital conversion ADC value is calculated according to the radio frequency signal by acquiring the radio frequency signal transmitted by the radio frequency output end. Then, a preset analog-to-digital conversion ADC value range corresponding to the working mode of the communication module is obtained, and it is determined whether the analog-to-digital conversion ADC value is within the preset analog-to-digital conversion ADC value range. If the analog-to-digital conversion ADC value is not within the preset analog-to-digital conversion ADC value range, an abnormal prompt message is sent, so that the tester can analyze and judge the abnormal situation of the communication module in the working mode according to the prompt message.

Please refer to FIG. 2 , which is a flowchart of a second preferred embodiment of the method for detecting abnormality of a communication module of the present invention. The communication module of the present invention can be applied to electronic devices such as notebooks, tablet computers, mobile phones, and wearable devices that require communication functions, which are not specifically limited herein.

Step S201: setting the maximum power value and the minimum power value of the radio frequency signal transmitted by the communication module in each working mode;

Step S202: obtaining the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value corresponding to the maximum power value and the minimum power value according to the calibration file;

Step S203: Store the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value, wherein the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value are two of the preset analog-to-digital conversion ADC value range. endpoint value;

Step S204: acquiring the radio frequency signal transmitted by the radio frequency output end, and calculating an analog-to-digital conversion ADC value according to the radio frequency signal;

Step S206: judging whether the analog-to-digital conversion ADC value is within the preset analog-to-digital conversion ADC value range;

Step S207: If the analog-to-digital conversion ADC value is not within the preset analog-to-digital conversion ADC value range, display the analog-to-digital conversion ADC value through the display screen of the communication device, and issue a text prompt that the communication module is abnormal information;

Step S208: Save the working mode of the communication module and the analog-to-digital conversion ADC value.

The method for detecting abnormality of a communication module in this embodiment will be described in detail below with reference to FIG. 2 . In the following description, a Wi-Fi communication module will be used as an example for description, and it can be understood that the method for detecting abnormality of a communication module can also be applied to other types of communication modules. The Wi-Fi communication module cannot be used to limit the scope of application of the present invention.

Because the preset analog-to-digital conversion ADC value range of the Wi-Fi communication module is different when it is in different working modes, before abnormal detection of the Wi-Fi communication module, it is necessary to store the communication with Wi-Fi in the memory of the communication device. The preset analog-to-digital conversion ADC value range corresponding to each operating mode of the module. The specific setting method of the preset analog-to-digital conversion ADC value range is shown in steps S201 to S203. It should be noted here that the working mode of the Wi-Fi communication module includes wireless transmission standard protocols and transmission rates. For example, the Wi-Fi communication module adopts the wireless transmission standard protocol of 802.11g and the working mode of the transmission rate of 54Mb/s.

In step S201, the Wi-Fi communication module has different requirements on the power value of the transmitted radio frequency signal in each working mode. Generally, the power value of the transmitted radio frequency signal is between the maximum power value and the minimum power value, so as to ensure the quality of the radio frequency signal transmitted by the Wi-Fi communication module. Therefore, the maximum power value and the minimum power value are set according to Chinese or international requirements on the power value of the transmitted radio frequency signal. Of course, the maximum power value and the minimum power value can also be set according to the needs of each communication device, which is not specifically limited here.

In step S202, since each communication device has a calibration file, the tester performs a calibration operation on each communication device according to the calibration file, so that each communication device can achieve good communication quality. The corresponding relationship between the power value of the transmitted RF signal and the analog-to-digital conversion ADC value is stored in the calibration file. Therefore, according to the calibration file, the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value corresponding to the maximum power value and the minimum power value can be obtained.

In step S203, after the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value are obtained, the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value are stored in the communication device. Specifically, the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value are stored in the radio frequency parameters of the Wi-Fi communication module. In this way, when the Wi-Fi communication module is subsequently detected, the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value can be read from the radio frequency parameter. It should be noted that the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value are respectively two endpoint values of the preset analog-to-digital conversion ADC value range.

In step S204, when the tester starts to detect the Wi-Fi communication module, the external device will send an instruction to the Wi-Fi communication module, so that the Wi-Fi communication module transmits a radio frequency signal with a corresponding power value according to the instruction. Specifically, the radio frequency output end of the Wi-Fi chip will transmit a radio frequency signal with a corresponding power value. The radio frequency signal is transmitted to the detector through the coupler. Here, the coupler can completely couple the radio frequency signal, or can couple a part of the power radio frequency signal according to a certain ratio, which is not specifically limited here.

After the detector receives the radio frequency signal coupled by the coupler, it will perform detection processing on the radio frequency signal, convert the high frequency radio frequency signal into a low frequency baseband signal, and transmit the low frequency baseband signal to the analog-to-digital converter, wherein The low-frequency baseband signal is an analog signal.

After receiving the low-frequency baseband signal, the analog-to-digital converter converts the analog baseband signal into a corresponding digital signal. At the same time, the analog-to-digital conversion ADC value corresponding to the digital signal is calculated, that is, the analog-to-digital conversion ADC value corresponding to the radio frequency signal output by the radio frequency output terminal of the Wi-Fi chip is calculated.

In steps S205 and S206, after the analog-to-digital converter calculates the analog-to-digital converted ADC value, the analog-to-digital converted ADC value is transmitted to the processing chip in the communication device. At the same time, the processing chip will obtain the preset analog-to-digital conversion ADC value range corresponding to the working mode of the Wi-Fi communication module. Specifically, the processing chip will obtain the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value from the radio frequency parameters of the communication module. Convert the ADC value to digital.

The processing chip will determine whether the analog-to-digital conversion ADC value is within the preset analog-to-digital conversion ADC value range. Specifically, the processing chip determines whether the analog-to-digital conversion ADC is within the preset analog-to-digital conversion ADC value range by comparing the analog-to-digital conversion ADC value with the maximum analog-to-digital conversion ADC value and the minimum analog-to-digital conversion ADC value. If the processing chip determines that the analog-to-digital conversion ADC value is within the preset analog-to-digital conversion ADC value range, it indicates the power value of the radio frequency signal transmitted by the Wi-Fi chip and the specified power value in the command sent by the external device. Basically the same, that is, the Wi-Fi communication module is in a normal state in the current working mode, and the tester can detect the next working mode at this time, that is, step S204 is executed.

If the processing chip determines that the analog-to-digital conversion ADC value is not within the preset analog-to-digital conversion ADC value range, it indicates the power value of the radio frequency signal transmitted by the Wi-Fi chip and the specified power value in the command sent by the external device. The size deviation is very large, that is, the Wi-Fi communication module is in an abnormal state in the current working mode. At this time, the display screen of the communication device will display the analog-to-digital conversion ADC value, and send out a text prompt message that the Wi-Fi communication module is abnormal, that is, step S207 is executed. In this way, the tester can watch the analog-to-digital conversion ADC value in this working mode on the display screen, and analyze and judge the abnormal cause in the working mode.

In step S208, when the Wi-Fi communication module is tested, its multiple working modes are often tested continuously. In addition, the test items are not limited to the radio frequency signal power test, but also other types of tests. In order to make a unified judgment and analysis of abnormal items, when it is detected that the power value of the radio frequency signal transmitted by the Wi-Fi communication module in a certain working mode is abnormal, the communication device will save the working mode and phase of the Wi-Fi communication module. The corresponding analog-to-digital conversion ADC value, so that after completing the whole test of the Wi-Fi communication module, the tester can read the abnormal working mode and the corresponding analog-to-digital conversion ADC value from the communication device, and carry out the abnormal phenomenon. Analysis and judgment to improve test efficiency.

In the method for detecting abnormality of the communication module in this embodiment, the two end values of the preset analog-to-digital conversion ADC value range are obtained by setting the power value of the radio frequency signal transmitted by the communication module. When the communication module is detected, the radio frequency signal emitted by the radio frequency output terminal is obtained first, the analog-to-digital conversion ADC value is calculated according to the radio frequency signal, and then the preset analog-to-digital conversion ADC value range corresponding to the working mode of the communication module is obtained, and Determine whether the analog-to-digital conversion ADC value is within the preset analog-to-digital conversion ADC value range. If the analog-to-digital conversion ADC value is not within the preset analog-to-digital conversion ADC value range, an abnormality prompt message will be sent, and the working mode and the corresponding analog-to-digital conversion ADC value will be saved, so that the tester can detect the abnormality after completing the test. In the working mode, unified analysis and judgment are carried out, so as to improve the efficiency of abnormal detection of communication modules.

At this time, the judgment unit 405 will send a sixth signal to the prompting unit 406, so that the prompting unit 406 will display the analog-to-digital converted ADC value on the display screen of the communication device according to the sixth signal, and issue a warning that the Wi-Fi communication module is abnormal. Text prompt information. In this way, the tester can watch the analog-to-digital conversion ADC value in this working mode on the display screen, and analyze and judge the abnormal cause in the working mode.

In addition, the test items are not limited to the RF signal power test, but also other kinds of tests. In order to make a unified judgment and analysis of the abnormal situation, when it is detected that the power of the radio frequency signal transmitted by the Wi-Fi communication module in a certain working mode is abnormal, the prompting unit 406 will send the abnormal prompting information to the saving unit 407 after completing the sending. The seventh signal enables the storage unit 407 to save the working mode of the Wi-Fi communication module and the corresponding analog-to-digital conversion ADC value according to the seventh signal, so that after completing the entire test of the Wi-Fi communication module, the tester can The device reads the abnormal working mode and the corresponding analog-to-digital conversion ADC value, and analyzes and judges the abnormal phenomenon.

In the communication module abnormality detection device 400 in this embodiment, the setting unit 401 sets two end-point values of the preset analog-to-digital conversion ADC value range, and the storage unit 402 stores the two end-point values. When abnormality detection is performed on the communication module, the acquisition and calculation unit 403 will acquire the radio frequency signal transmitted by the radio frequency output end, and calculate the analog-to-digital conversion ADC value according to the radio frequency signal. Then, the acquisition unit 404 acquires the preset analog-to-digital conversion ADC value range corresponding to the working mode of the communication module. The determination unit 405 determines whether the analog-to-digital conversion ADC value is within a preset analog-to-digital conversion ADC value range. If the judging unit 405 judges that the analog-to-digital conversion ADC value is not within the preset analog-to-digital conversion ADC value range, the prompting unit 406 sends an abnormal prompt message, and the saving unit 407 saves the working mode and the corresponding analog-to-digital conversion ADC value, so that the tester can make a unified analysis and judgment on the abnormal working mode after completing the test, so as to improve the efficiency of abnormal detection of the communication module.
