Description

Technical Field

[0001] The embodiments of the present application relate to the field of intelligent terminal technology, and in particular to a control signal sending method, a control signal receiving method and related equipment. Background Art

[0002] With the rapid development of mobile communications, various mobile terminals emerge in an endless stream. In the production process of mobile terminals, various mobile terminals need to be subjected to performance tests, including radio frequency tests. Radio frequency is an electromagnetic frequency that can be radiated into space, with a frequency range of 300KHz-300GHz.

[0003] At present, in the process of performing radio frequency testing on mobile terminals, the problem of signal interference is usually encountered; for example, when performing an Over The Air (OTA) test on a mobile terminal, a control signal needs to be sent to the mobile terminal in order to control the frequency band of the mobile terminal, thereby performing a radio frequency test; however, if the signal of the mobile terminal is controlled by a wireless method such as WIFI, the WIFI signal will interfere with the test signal; and if the signal of the mobile terminal is controlled by a wired method such as a USB cable, the cable will reflect the test signal, thereby interfering with the test signal. Therefore, how to solve the interference of the control signal on the test signal during the radio frequency test has become a problem that needs to be solved urgently. Summary of the invention

[0004] The embodiments of the present application provide a control signal sending method, a receiving method and related equipment to provide a control signal sending and receiving method, which can realize signal control of the tested device through sound in a radio frequency test environment, thereby avoiding interference of the control signal to the test signal and improving the efficiency of radio frequency testing.

[0005] In a first aspect, an embodiment of the present application provides a method for sending a control signal, including:

[0006] detecting a first operation for generating control signaling;

[0007] Specifically, the first operation may be an operation input by a user, and the operation may be used to generate an instruction to control the device under test, for example, to adjust a radio frequency band of the device under test.

[0008] In response to the first operation, generating a control signaling, and converting the control signaling into a binary code stream;

[0009] The audio coding signal is modulated and then sent to a receiving end.

[0010] Specifically, the binary code stream obtained by converting the control signaling can be encoded to obtain audio code, and then the audio code is modulated to generate a sound waveform signal, and finally the sound signal can be transmitted through a speaker or the like.

[0011] In one possible implementation, performing audio encoding on the binary code stream to obtain an audio encoding signal includes:

[0012] Compressing the binary code stream to obtain a data frame, and adding a frame header to the data frame, wherein the frame header includes a synchronization code and a cyclic redundancy check (CRC) code;

[0013] The data frame is encoded to obtain an audio encoding signal.

[0014] Specifically, the compression is used to improve the data transmission efficiency. Since the data rate of sound transmission is low, the amount of data transmitted each time can be increased through compression, thereby improving data transmission efficiency; the data frame header is used to parse the compressed data frame at the receiving end.

[0015] In one possible implementation manner, before the detecting a first operation for generating a control signaling, the method further includes:

[0016] In response to the received correction signal, performing signal strength analysis on the correction signal to obtain channel compensation;

[0017] The step of modulating the audio coding signal and sending it to the receiving end comprises:

[0018] The audio coding signal is modulated according to the channel compensation and then sent to a receiving end.

[0019] Specifically, the correction signal is used to compensate for channels of different tested devices. Since different tested devices have different sound gains, the correction signal can be sent before sending the control signal to compensate for the channel, thereby avoiding bit errors or missing bits caused by channel differences.

[0020] In one possible implementation manner, after the audio coding signal is modulated and sent to the receiving end, the method further includes:

[0021] If a non-confirmation message is received from the receiving end, the audio coding signal is retransmitted.

[0022] Specifically, the non-confirmation message corresponds to the audio coding information. When the non-confirmation message is received, the corresponding audio coding signal can be retransmitted, thereby improving the efficiency of data transmission and further improving the efficiency of radio frequency testing.

[0023] The embodiment of the present application also provides a method for receiving a control signal, including:

[0024] receiving an audio coding signal from a transmitting end;

[0025] Specifically, the sound signal may be received by a microphone of the device under test. Since the sound signal is continuous, the sound signal within any time period may be sampled.

[0026] Demodulating the audio coding signal to obtain a frequency of the audio coding signal;

[0027] Specifically, the analog signal of the sound may be demodulated into a digital signal, and the demodulation method may be a fast Fourier transform, thereby obtaining the corresponding frequency and component in the sound signal.

[0028] The audio coding signal is decoded according to the frequency to obtain a binary code stream, and the binary code stream is parsed to obtain a control signaling.

[0029] Specifically, the transmitting end may perform encoding according to the codewords in the audio encoding table, and thus the receiving end may also perform decoding according to the codewords in the audio encoding table, thereby obtaining a binary code stream.

[0030] In one possible implementation manner, before receiving the audio coding signal from the transmitting end, the method further includes:

[0031] Send a correction signal to the transmitter.

[0032] Specifically, before the tested device waits to receive the control signal from the testing device, when initializing the communication module, it can send a correction signal to the testing device (transmitting end), and the correction signal can be a 5kHz or 8kHz pilot signal.

[0033] In one possible implementation, decoding the audio coding signal according to the frequency to obtain a binary code stream includes:

[0034] Decoding the audio coding signal according to the frequency to obtain a data frame;

[0035] Performing frame synchronization detection according to a synchronization code in a frame header of the data frame, and performing integrity detection according to a cyclic redundancy check (CRC) code in a frame header of the data frame;

[0036] If the frame synchronization detection and integrity detection are successful, the data frame is decompressed to obtain a binary code stream.

[0037] Specifically, if the sender compresses the binary code stream, a data frame can be obtained after decoding the audio coding signal. Then, the data frame can be synchronized and checked for integrity based on the frame header in the data frame, and decompressed after the check is successful, thereby obtaining a binary code stream.

[0038] In one possible implementation, if the frame synchronization detection and integrity detection are successful, the data frame is decompressed to obtain a binary code stream including:

[0039] If the frame synchronization detection and integrity detection are successful, the data frame is decompressed to obtain a binary code stream, and a confirmation message is sent to the sending end;

[0040] If the frame synchronization detection or integrity detection fails, a non-confirmation message is sent to the sending end to request the sending end to retransmit the data frame.

[0041] Specifically, the confirmation message or non-confirmation message corresponds to a data frame. When the transmitting end receives a confirmation message or non-confirmation message of any data frame, it can determine whether to retransmit the data frame according to the message.

[0042] In the above-mentioned control signal sending method and receiving method, the control signal is carried by sound at the sending end, and the sound signal is modulated and sent to the receiving end. The sound signal is demodulated at the receiving end to obtain the carried control signal, thereby providing a control signal sending and receiving method, which can realize signal control of the tested device by sound in a radio frequency test environment, thereby avoiding interference of the control signal to the test signal and improving the efficiency of radio frequency testing.

[0105] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0106] In existing implementation schemes, the test equipment controls the signals of the tested device such as the mobile terminal by wired or wireless means, thereby performing RF testing on the tested device. However, in the process of sending the control signal, interference will be caused to the test signal sent by the tested device.

[0107] To this end, the present application proposes a method for sending and receiving a control signal, which can realize signal control of the device under test in a darkroom environment, thereby avoiding interference with the test signal during the RF test process, thereby improving the efficiency of the RF test.

[0108] Figure 1 This is a flow chart of an embodiment of a method for sending a control signal of the present application, as shown in FIG. Figure 1 As shown, the method for sending the control signal may include:

[0109] Step 101: Generate a binary code stream at the sending end.

[0110] Specifically, the transmitting end can be a test device, such as a radio frequency tester; the binary code stream can be generated based on a control signal, and the control signal can be input by a user. When the test device detects the user's current operation, it can generate a corresponding control signal based on the operation, and then the control signal can be converted into binary to obtain a binary code stream.

[0111] It should be understood that a binary code stream is a string of 0s and 1s, which can be parsed at the receiving end to obtain control signaling.

[0112] Step 102: Perform audio encoding on the binary code stream to obtain an audio encoding signal.

[0113] Specifically, after obtaining the binary code stream, the binary code stream can be encoded based on audio. Since the sound signal has the characteristics of a wireless signal in signal transmission, and has low development cost and small interference, the binary code stream can be encoded into audio code.

[0114] In the process of audio encoding, a dual tone multi-frequency (DTMF) signal can be used, that is, a binary code stream can be encoded into a DTMF code, and the DTMF code can be queried through a DTMF code table, so that the received DTMF code can be decoded into a binary code stream by querying the DTMF code table at the receiving end.

[0115] Optionally, since DTMF has only 14 characters, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C and D, and DTMF also includes the characters "*" and "#", the character "*" can be changed into the hexadecimal character "E", and the character "#" can be changed into the hexadecimal character "F", thereby forming a hexadecimal code, that is, the DTMF code can be a hexadecimal code.

[0116] Furthermore, since the audio transmission data rate is low, the binary code stream can be compressed before audio encoding is performed on the binary code stream, thereby improving the data transmission efficiency; wherein, the data compression can be performed using a control protocol; in specific implementation, after the binary code stream is compressed, a corresponding data frame can be obtained, and a frame header can be added to the data frame to identify the data frame. The frame header can include a synchronization code and a CRC code, wherein the synchronization code is used to check the synchronization of the data frame, and the CRC code is used to check the integrity of the data frame. Then the data frame is audio encoded.

[0117] Step 103: Send the audio coding signal to a receiving end.

[0118] Specifically, after obtaining the audio coding signal, since the audio coding signal is a digital signal, digital-to-analog conversion can be performed, that is, the digital signal is modulated and converted into an analog signal, and the analog signal can be transmitted through a sound card or a speaker so that the receiving end can receive the analog signal.

[0119] In one possible implementation, since different devices under test may have different sound gains for different frequencies, and the current environment may cause differences in the sound silencing effect, the gain curve of the transmission channel can also be estimated to obtain channel compensation; in specific implementation, the estimation can be performed by receiving a correction signal sent by the receiving end, and the correction signal can be sent when the receiving end (device under test) initializes the communication module in the RF test scenario. The correction signal can be a 5KHz or 8KHz pilot signal; when the transmitting end (test device) receives the correction signal, the signal strength analysis of the correction signal can be performed to calculate the gain curve of the channel, and the corresponding channel compensation can be determined based on the gain curve. For example, when modulating the signal, the following modulation function can be used:

[0120] W=A*k*sin(x1)+A*k*sin(x2),

[0121] Among them, W can be the waveform of the sound signal, A can be the signal amplitude, k can be the compensation factor, x1 and x2 can be the frequencies of DTMF. After the waveform of the sound is generated according to the modulation function, the sound card or speaker can be driven to make sound according to the sound signal, thereby sending the signal.

[0122] In one possible implementation, due to the uncertainty of the wireless communication channel, the data sent through the wireless signal may fail to be received. Therefore, in order to improve the efficiency of data transmission, the transmitted data can be retransmitted; in the specific implementation, physical layer retransmission, that is, hybrid automatic repeat request (HARQ) can be used. After the data frame is sent by the transmitting end, the data frame can be stored in a pre-set cache. If a non-acknowledgement (NACK) message is received from the receiving end, the corresponding data frame can be retransmitted. If an acknowledgment (ACK) message is received from the receiving end, the corresponding data frame can be deleted from the cache; Figure 2 As shown, the sending end sends the audio coding signal A and the audio coding signal B in sequence. When the receiving end receives the audio coding signal A, it performs synchronization check and integrity check. After success, it sends an ACK message to the sending end. When the receiving end receives the audio coding signal B, it performs synchronization check and integrity check. After failure, it sends a NACK message to the sending end. When the sending end receives the ACK message, it deletes the audio coding signal A. When the sending end receives the NACK message, it retransmits the audio coding signal B. After receiving the audio coding signal B, the receiving end performs synchronization check and integrity check again. After success, it sends an ACK message to the sending end. When the sending end receives the ACK message, it deletes the audio coding signal B.

[0123] In this embodiment, a control signal is carried by sound at the transmitting end, and the sound signal is modulated and sent to the receiving end, thereby providing a method for sending a control signal. Signal control of the device under test can be performed by sound in a radio frequency test environment, thereby avoiding interference of the control signal on the test signal and improving the efficiency of radio frequency testing.

[0124] Figure 3 This is a flow chart of an embodiment of a method for receiving a control signal of the present application, as shown in FIG. Figure 2 As shown, the method for receiving the control signal may include:

[0125] Step 301: Receive an audio coding signal from a transmitting end.

[0126] Specifically, an audio coding signal can be received at the receiving end. Since the audio coding signal is an analog signal, the audio coding signal can be sampled and the sampled signal can be demodulated, that is, the analog signal is converted into a digital signal. In a specific implementation, the demodulation method can be a fast Fourier transform (FFT) calculation to obtain the frequency of the sampled signal.

[0127] In the sampling process, the audio coding signal can be sampled by a continuous sliding window method to ensure the continuity of the data.

[0128] In one possible implementation, before step 201, a correction signal may be sent to the transmitting end to compensate for the channel; the correction signal may be sent when the receiving end initializes the communication module, and the correction signal may be a 5KHz or 8KHz pilot signal.

[0129] Step 302: Obtain a binary code stream according to the audio coding signal.

[0130] Specifically, after the audio coding signal is demodulated, the corresponding DTMF code can be obtained, and then the DTMF code can be decoded according to the obtained frequency. The decoding process can be to query the DTMF coding table according to the code corresponding to the signal frequency to obtain decoded data. The decoded data can be a data frame, that is, a compressed binary code stream.

[0131] Optionally, due to the changeable environment of the wireless channel, the duration of data transmission varies, that is, the data sent after the sending end may arrive at the receiving end first, resulting in inconsistent order of arrival of different data frames at the receiving end; therefore, after obtaining the data frame, a synchronization check can be performed based on the synchronization code in the data frame header, thereby ensuring the synchronization between the sending end and the receiving end, thereby ensuring the correctness of the data frame decoding.

[0132] Furthermore, since data may be erroneous or lost during transmission, the data frame may be integrity checked to ensure the integrity of the received data frame, wherein the integrity check may be completed by checking the CRC code in the data frame header.

[0133] Furthermore, if both the synchronization check and the integrity check are passed, the data frame can be decompressed to obtain a corresponding binary code stream, wherein the decompression method can correspond to the compression method of the sending end.

[0134] Optionally, the receiving end may also send an ACK message to the sending end to confirm that the data frame has been correctly received.

[0135] If any of the synchronization check and integrity check fails, a NACK message may be sent to request the sender to retransmit the data frame.

[0136] Step 303: parse the binary code stream to obtain control signaling.

[0137] Specifically, after obtaining the binary code stream, the binary code stream can be parsed, and the parsing process can correspond to the binary conversion process of the transmitter, thereby obtaining the corresponding control signaling to achieve control of the device under test, for example, setting the RF test frequency band of the device under test.

[0138] In this embodiment, a sound signal is demodulated at the receiving end to obtain a carried control signal, and the device under test is controlled by the control signal, thereby providing a control signal receiving method that can realize signal control of the device under test by sound in a radio frequency test environment, thereby avoiding interference of the control signal on the test signal and improving the efficiency of radio frequency testing.
