The user equipment may be fixed or mobile. It should be noted that the ue may support at least one wireless communication technology, such as LTE, new Radio (NR), wideband Code Division Multiple Access (WCDMA), and so on. For example, the user device may be a mobile phone (mobile phone), a tablet (pad), a desktop, a notebook, a kiosk, a car terminal, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote management), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (city), a wireless terminal in smart home (smart home), a cellular phone, a cordless phone, a session initiation protocol (session initiation protocol), SIP) phones, wireless Local Loop (WLL) stations, personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, wearable devices, terminal devices in future mobile communication networks or terminal devices in future evolved public mobile land networks (PLMNs), and the like.

At present, in the test of delay of a touch sound loop of a screen on an electronic device, an additional mobile phone is used for shooting a device to be tested at a high frame rate, a shot video is copied to a computer, image tracks are manually consulted frame by frame, color change of a certain area of the screen is used as an initial signal, a time point when a sound signal of a sound track in the video changes is used as an end signal, and the delay is calculated. The delay test of the screen touch sound-emitting loop is incomplete, and the delay from the clicking of the screen to the color-changing reaction is lacked, generally speaking, the delay is about 100ms, so that it is difficult to ensure that the image and the sound track of the mobile phone for shooting the test action are synchronously acquired, and errors are introduced due to the asynchronous process. Different mobile phones are used for shooting, the obtained delay values are inconsistent, and the error is caused by the fact that the images and sound of the mobile phones are shot asynchronously. Manual frame-by-frame viewing is required and is inefficient.

In view of the above problems, embodiments of the present application provide an operation time-consuming test system, a signal processing device, and a signal processing method, which are described below with reference to the accompanying drawings.

Referring to fig. 1a, fig. 1a is a schematic diagram of an architecture of an operation time-consuming test system 10 according to an embodiment of the present disclosure, where the operation time-consuming test system 10 includes a signal processing device 100, a sound pickup device 200, a touch device 300, and a device under test 400, the signal processing device is respectively connected to the sound pickup device and the touch device, and in this case,

the touch device 300 is configured to contact the touch screen 410 of the device under test 400 to generate a pressure signal.

Wherein the touch device 300 simulates a scene where a human hand touches the display screen by contacting the touch screen 410.

For example, the touch device 300 may be a stylus.

The device under test 400 is configured to detect a touch signal and output a sound signal according to the touch signal when the touch device 300 contacts the touch screen 410.

For example, the device under test 400 may be, for example, the aforementioned user equipment, a mobile phone, a tablet, or the like.

The sound pickup apparatus 200 is configured to collect the sound signal.

Illustratively, the sound pickup apparatus 200 may be a high-sensitivity microphone.

The signal processing device 100 is configured to collect the pressure signal and the sound signal, and determine operation time consumption of a preset operation according to the pressure signal and the sound signal, where the preset operation is the following operation performed by the device under test 400: and detecting the touch signal and outputting a sound signal according to the touch signal.

For example, the signal processing device 100 may be a platform device integrating a computer, a sound card and a pressure strain signal acquisition card, and running codes for testing the delay of a touch acoustic loop of a screen. The platform device simulates the brain of a user, is used for sensing the delay of a screen touch sound-producing loop and gives ms-level delay feedback.

In some embodiments, please refer to fig. 1b, where fig. 1b is a schematic structural diagram of a signal processing apparatus 100 according to an embodiment of the present disclosure; the signal processing device 100 is provided with an on-board clock 110, a sound card 120 and a pressure strain signal acquisition card 130, wherein the on-board clock 110 is respectively connected with the sound card 120 and the pressure strain signal acquisition card 130;

the on-board clock 110 is configured to provide a first sampling clock for the sound card 120, and provide a second sampling clock for the pressure strain signal acquisition card 130;

the sound card 120 is configured to collect the sound signal;

the pressure strain signal acquisition card 130 is configured to acquire the pressure signal.

Illustratively, the offset of the first sampling clock and the second sampling clock is less than 10 microseconds, and the synchronous sampling frequency of 100KHz can be set at the highest.

Therefore, in the example, the signal processing device can achieve synchronous acquisition precision of 0.01ms (far below the reaction time of people) level sound and strain, so that errors caused by asynchronous signal acquisition are eliminated, and delay of a screen touch sound-emitting loop is accurately calculated.

In some embodiments, the signal processing apparatus 100 is specifically configured to: determining a first time according to the pressure signal, where the first time is used to indicate a time of a first touch signal detected by the device under test 400, and the first touch signal corresponds to a starting time of contact between the touch device 300 and the touch screen 410; determining a second time according to the sound signal, wherein the second time is used for indicating the starting moment of the sound production of the device under test 400; and determining an operation time consumption of a first preset operation according to the first time and the second time, wherein the preset operation refers to the following operations executed by the device under test 400: and detecting the first touch signal, and outputting a sound signal according to the first touch signal.

And the operation time obtained by subtracting the first time from the second time is delayed for a screen touch sound-emitting loop in a scene where touch contact is generated.

As can be seen, in this example, the signal processing device can accurately calculate the delay of the screen touch sounding loop in the scene where the touch is sounding.

In some embodiments, the signal processing apparatus 100 is specifically configured to: generating a signal waveform diagram according to the acquired pressure signal and the acquired sound signal, identifying a first rising edge pulse signal and a second rising edge pulse signal in the pressure signal waveform diagram, determining the first time corresponding to the first rising edge pulse signal, and determining the second time corresponding to the second rising edge pulse signal.

In the specific implementation, when the touch device is used for simulating a user touch screen, because the touch device integrates a strain sensor (a pressure detection unit), when the strain changes, a voltage signal changes simultaneously, when the touch device leaves the screen, the strain recovers, and the voltage also recovers to a stable state, so that in the whole touch process, the touch device can generate a section of pulse signal, wherein a rising edge corresponds to a moment T1 (namely a first time) when the touch device initially contacts the screen, a falling edge corresponds to a moment T2 (namely a third time) when the touch device leaves the screen, and the width of the pulse signal corresponds to a time when the touch device applies pressure and the screen contacts. The electronic equipment detects a touch signal of the touch screen, and finally excites devices such as a loudspeaker to emit a sound signal through a series of internal signal processing including screen response, network response, system response and the like, wherein the sound signal can be collected by sound pickup equipment which is arranged near the devices. The change that sound signal was received to the adapter equipment can change into the change of voltage signal, and this voltage signal can be gathered by the sound card. Since the voltage signal generated by the sound pickup apparatus that receives the sound signal in the sound emission environment is significantly changed from the voltage signal generated in the quiet environment, the time T3 (i.e., the second time) when the device emits sound can be detected by setting a threshold value to the voltage waveform.

For a scene where touch contact is sounding, the loop delay value of the screen touch sounding is: Δ T1= T3-T1.

For the scenario where the touch release is only used for sounding, the loop delay value of the screen touch sounding is as follows: Δ T2= T3-T2.

For example, as shown in fig. 1c, fig. 1c is an exemplary diagram of a signal waveform diagram provided in this embodiment, where a dotted line is a voltage signal acquired by a pressure strain signal acquisition card, and a solid line is a voltage signal waveform acquired by a sound card, and time values of T1, T2, and T3 can be calculated very quickly by detecting a threshold. Therefore, the delay of the touch sounding loop of the screen is calculated according to the formula.

As can be seen, in this example, the signal processing device can identify the critical moment through analysis of the signal waveform diagram, and accurately calculate the delay of the screen touch sounding loop in the scene where the touch contact is sounding.

In some embodiments, the signal processing apparatus 100 is specifically configured to: determining a third time according to the pressure signal, where the third time is used to indicate a time of a second touch signal detected by the device under test 400, and the second touch signal corresponds to a termination time of contact between the touch device 300 and the touch screen 410; determining a second time according to the sound signal, wherein the second time is used for indicating the starting moment of the sound production of the device under test 400; and determining an operation time consumption of a second preset operation according to the third time and the second time, wherein the second preset operation refers to the following operations executed by the device under test 400: and detecting the second touch signal and outputting a sound signal according to the second touch signal.

And the operation time obtained by subtracting the first time from the third time is delayed for a screen touch sounding loop in the scene sounding only by touch release.

As can be seen, in this example, the signal processing device can accurately calculate the delay of the screen touch sounding loop in the scene where the sound is generated only by the touch release.

In some embodiments, the signal processing apparatus 100 is specifically configured to: generating a signal waveform diagram according to the pressure signal and the sound signal, identifying a falling edge pulse signal and a second rising edge pulse signal in the pressure signal waveform diagram, determining the third time corresponding to the falling edge pulse signal, and determining the second time corresponding to the second rising edge pulse signal.

In this example, the signal processing device can analyze and identify the critical moment through the signal oscillogram, and accurately calculate the delay of the screen touch sounding loop in the scene where the sounding is performed only by the touch release.

In some embodiments, please refer to fig. 1d, where fig. 1d is a schematic structural diagram of a touch device 300 according to an embodiment of the present disclosure; the touch device 300 is integrated with a pressure detection unit 310, and the pressure detection unit 310 is used for generating the pressure signal.

The touch device can be a stylus with a nib integrated with a pressure-strain sensor.

Therefore, in this example, when the touch device contacts the touch screen of the device to be tested, strain occurs, and thus a voltage signal changes, and the signal is collected by the pressure strain signal collection card integrated in the signal processing device. The touch control equipment realizes the operation of simulating a user to touch the screen by hands.

In some embodiments, please refer to fig. 1e, where fig. 1e is a schematic structural diagram of a device under test 400 provided in the present embodiment; the device under test 400 includes a speaker 420, and the speaker 420 is configured to output the sound signal.

As can be seen, in this example, the device under test plays the sound signal through the speaker.

In some embodiments, please refer to fig. 1f, where fig. 1f is a schematic structural diagram of a signal processing apparatus 100 according to an embodiment of the present disclosure; the signal processing apparatus 100 further comprises a display screen 140, and the signal processing apparatus 100 is further configured to display a delay detection interface on the display screen 140, where the delay detection interface is configured to set at least one of the following parameters: sampling rate, acquisition length, test scheme, file saving path, and filter configuration.

The sampling rate is used for synchronously setting the sampling frequency of the sound signal and the pressure signal, the sampling length corresponds to the sampling duration, the test scheme corresponds to different selectable modes, if the touch contact is tested, namely, the sound is generated to be the first mode, the touch release is performed, the sound is generated to be the second mode, and the filter is configured to configure specific filtering parameters and the like.

For example, the exemplary diagram of the delay detection interface shown in fig. 1g includes a waveform diagram display area and a function configuration area, the waveform diagram display area displays coordinate information, and the function configuration area displays a start test, a stop test, a time consumption calculation result display component, and the like.

As can be seen, in the present example, the signal processing device supports intuitive presentation of the delay calculation result and the auxiliary parameter configuration through the interface.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a signal processing device 100 according to an embodiment of the present disclosure, where the signal processing device 100 includes a processor 150, an on-board clock 110, a sound card 120, a pressure-strain signal acquisition card 130, and a display screen 140, the on-board clock 110 is respectively connected to the sound card 120, the pressure-strain signal acquisition card 130, and the processor 150 is connected to the display screen 140;

the sound card 120 is configured to collect the sound signal;

The signal processing apparatus 100 is further configured to display a delay detection interface on the display screen 140, where the delay detection interface is configured to set at least one of the following parameters: sampling rate, acquisition length, test scheme, file saving path, and filter configuration.

Referring to fig. 3, fig. 3 is a schematic flowchart of a signal processing method applied to a signal processing apparatus according to an embodiment of the present application, where the method includes the following steps:

step 301, collecting a pressure signal and a sound signal, where the pressure signal is a signal generated by the touch device when the touch device contacts the touch screen of the device to be tested, the sound signal is a sound signal output by the device to be tested collected by the pickup device according to the touch signal, and the touch signal is a signal detected by the device to be tested when the touch device contacts the touch screen.

Step 302, determining an operation time consumption of a preset operation according to the pressure signal and the sound signal, where the preset operation is performed by the device under test as follows: and detecting the touch signal and outputting a sound signal according to the touch signal.

It can be seen that, in the embodiment of the application, because the touch device and the sound pickup device can simulate the delay of a complete loop from the time when a user touches a screen to the time when the user hears sound, the signal processing device can automatically calculate the delay, thereby simplifying manual operation and improving the testing efficiency and accuracy.
