The electronic apparatus 100 may also calculate the touched position from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but have different touch operation intensities may correspond to different operation instructions. For example: and when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message.

The temperature sensor 180J is used to detect temperature. In some embodiments, electronic device 100 implements a temperature processing strategy using the temperature detected by temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 performs a reduction in performance of a processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, the electronic device 100 heats the battery 142 when the temperature is below another threshold to avoid the low temperature causing the electronic device 100 to shut down abnormally. In other embodiments, when the temperature is lower than a further threshold, the electronic device 100 performs a boost on the output voltage of the battery 142 to avoid abnormal shutdown due to low temperature.

The touch sensor 180K is also referred to as a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is used to detect a touch operation acting thereon or nearby. The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 194. In other embodiments, the touch sensor 180K may be disposed on a surface of the electronic device 100, different from the position of the display screen 194.

The front-end module may be an image preprocessor.

Optionally, in step 301, the virtual video device is set, which may be implemented as follows:

and setting the virtual video equipment through a Mobile Industry Processor Interface (MIPI) of the front-end module.

For example, if the amount of information generated by the front-end module in a certain time is small, the buffer register may be insufficiently filled, and the buffer register and the transmission bandwidth may be wasted, so that data may also be packed based on the principle of being filled and sent immediately, and the packed data and the next frame of data are transmitted to the AP together for processing, or the packed data may be time-stamped and sent to the AP for processing separately, so as to save the transmission bandwidth.

In a specific implementation, the electronic device may detect whether the electronic device is in an engineering mode, and may execute step 301 when the electronic device is in the engineering mode, otherwise, step 301 may not be executed. The engineering mode can be set by a user, or the electronic equipment automatically enters the engineering mode when the electronic equipment is abnormal.

The number of cache registers may be set at the discretion of the user or may be determined by the bandwidth and/or speed of generation of the operational data.

The electronic device may also display the operational data via a display screen. In the embodiment of the application, the first frame rate and/or the second frame rate can be dynamically adjusted, so that effective encapsulation and packet transmission of the operation data are guaranteed.

Specifically, whether the front-end module is abnormal or not may be determined at least partially based on adjusting the value of the first frame rate, or whether the front-end module is abnormal or not may be determined at least partially based on adjusting the value of the second frame rate, or whether the front-end module is abnormal or not may be determined at least partially based on adjusting the values of the first frame rate and the second frame rate, that is, in a specific implementation, it is possible to adjust some or all of the operation data at the first frame rate or the second frame rate, so as to facilitate efficient transportation data transmission by the front end in a rhythmic manner, and to facilitate fast extraction of the operation data by the back end in a rhythmic manner, and during the adjustment, the target data packet may be analyzed to obtain the operation data of the front-end module, and it may be determined whether the front-end module is abnormal or not by the operation data.

For example, in the embodiment of the present application, the electronic device processes the virtual video device of the abnormal information collection module in the front-end module, so that the abnormal information (including detection information during running) of different modules can be collected and packaged at the front end according to a certain rhythm and size, so as to be output to the PC side in real time, and when a developer needs to perform debugging, the reason why a problem occurs can be obtained by analyzing received monitoring data.

Further, for example, in the embodiment of the present application, when the operation data is image data, for example, a processing effect (for example, an effect of some areas) of each frame may be compared with a pre-stored standard effect graph to obtain a result of determining the processing effect of the current frame, and further, a processing parameter of a correlation algorithm is adaptively adjusted according to the result of determining, so that image processing of the camera system can stably perform image processing.

and C3, determining target abnormal information according to the target operation result.

The preset neural network model may be at least one of the following: convolutional neural network models, fully-connected neural network models, recurrent neural network models, and the like, without limitation.

The set of target features may include at least one feature, or the set of target features may include at least one class of features. When the operational data is image data, the characteristic may be at least one of: feature points, feature vectors, colors, pixels, feature lines, and the like, which are not limited herein.

When the operational data is debug data, the characteristic may be at least one of: level, waveform, voltage, current, power, log data, etc., without limitation.

Before executing step 301 in the embodiment of the present application, a neural network model may be trained through a large amount of sample data and labels corresponding to the samples, and after the neural network model converges, a preset neural network model may be obtained.

In a specific implementation, the electronic device may perform feature extraction on the operation data to obtain a target feature set, then input the target feature set to a preset neural network model to obtain a target operation result, where the operation result may be at least one tag and a corresponding probability value, then generate an anomaly analysis report according to the target operation result, and use the anomaly analysis report as target anomaly information, or may also store a mapping relationship between the operation result and the anomaly information in advance in the electronic device, and then determine target anomaly information corresponding to the target operation result according to the mapping relationship, where the anomaly information may be at least one of the following: the cause of the abnormality, the location of the abnormality, the duration of the abnormality, etc., are not limited herein.

For example, according to the embodiment of the present application, anomaly detection may be actively initiated on a system and an image through a front-end module, when an anomaly occurs, the anomaly may be detected in advance and relevant anomaly information may be obtained, and then, under the condition that an upper layer is not affected, that is, under the condition that a user experiences and calls an image preprocessor by the upper layer, adaptive processing corresponding to the anomaly may be quickly performed, and further, a processed result and anomaly information may be reported, so that the upper layer may make further judgment and processing according to the adaptive processing result and the anomaly information in time, thereby better improving robustness of the system, reducing the impact of the anomaly on user experience, and improving user experience.

As shown in fig. 3C, any data packet in the destination data packet may include a header PH, operation data, and a trailer PF, where the header may be used to mark a start position of a data packet, and the trailer may be used to indicate an end position of the data packet.

Further, the packet header may include: the data packet comprises a packet header mark, an index packet mark and a packet data length, wherein the packet header mark is used for indicating the data type of a current data packet, the index packet mark is used for indicating an independent index of the current data packet, and the packet data length is used for indicating the data length of the current data packet, and the specific structure is shown in the following table:

baotou structure	Length in bytes
		Heading label	Byte3
Index packet tag	Byte2
		Packet data length	Byte1+Byte0

Further, the packet trailer may include: an end-of-packet flag indicating the end-of-packet position, a packet count indicating the count (the number) of the packet, and a frame count indicating from which frame the packet came, as shown in the following table:

tail wrapping structure	Length in bytes
		Tailing label	Byte3
Packet counting	Byte2

Optionally, the method may further include the following steps:

and receiving the target data packet through the AP, unpacking the target data packet to obtain the operating data, wherein the operating data is used for realizing data analysis.

The AP may receive the target data packet, unpack the target data packet according to the first frame rate and/or the second frame rate, obtain operation data, and implement data analysis by using the operation data, so as to achieve the purpose of anomaly detection.

Optionally, in step 302, the target data packet is unpacked to obtain the operation data, which may be implemented as follows:

and unpacking the target data packet through a hardware abstraction module to obtain the operating data.

The unpacking is a reverse operation of a packing action, the hardware abstraction module can analyze a target data packet according to a flag bit or a predetermined rule, and then process the analyzed data, for example, the storage sequence can be adjusted or abnormal information can be packed into image data of a secondary camera when multiple paths of image data exist (the size of the image data of the secondary camera is small, and space and bandwidth can be used for transmitting debugging information), and the cache register of the primary camera only transmits the image data.

For example, as shown in fig. 3D, taking debug data as an example, an internal signal of the front-end module may be forwarded from the MIPI of the front-end module to the AP-side DDR, and the AP-side triggers an interrupt after receiving the data. Since the front-end module performs the packing process on the debug data as a virtual camera device (virtual video device), a special pipeline (pipeline) needs to be started in the hardware abstraction module to serve the virtual video device. Furthermore, the USB service needs to allocate a relevant cache register and send the cache register to the hardware abstraction module, and the hardware abstraction module needs to copy the obtained debug data to the cache register allocated to the USB service in a frame-by-frame manner. For the rotation of the cache register, the USB service side may implement the rotation of the cache register in a callback function (callback).

In the embodiment of the application, for the customization of the AP to the engineering mode and the pipeline configuration parameter, because integrity and differentiability of monitoring information of the front-end module need to be ensured, a data processing module of the AP needs to be selectively accessed during customization, for example, some modules that may affect data content may not be accessed, such as a noise reduction function module, so as to avoid tampering data. Furthermore, the processing of the cache register by the pipeline is different from that of a traditional camera processing module, and the data needs to be split and processed when the monitoring data and the image data are packed and transmitted, so that the cache register of the original data can be analyzed and recombined in the pipeline, the analysis and recombination of the data can be analyzed according to a flag bit or an agreed rule, and then the analyzed data are respectively processed.

Optionally, in the step 302, unpacking the target data packet to obtain the operation data may include the following steps:

31. copying the target data packet into a target cache register distributed by a USB service in a frame-by-frame mode;

32. and unpacking the data in the target cache register to obtain the operating data.

In the concrete implementation, the electronic device can copy the target data packet into a target cache register allocated by the USB service in a frame-by-frame mode through the hardware abstraction module, unpack the data in the target cache register through the hardware abstraction module to obtain running data, and after the target cache register is occupied, the cache register can be rotated so as to provide the next cache register for accommodating the data copied by the hardware abstraction module, and certainly, after the running data is uploaded to an upper computer PC, the data analysis can be realized through the upper computer.

Optionally, in step 302, after unpacking the target data packet to obtain the operating data, the method may further include the following steps:

and calling a USB service to upload the running data to external equipment through the target cache register so that the external equipment can perform data analysis on the running data.

Further, optionally, the method may further include the steps of:

and performing rotation operation on the target cache register, so that the target cache register after rotation is continuously used for accommodating the data packet received by the AP.

For example, when the front-end module performs debugging data and processing, information division and packing may be performed based on an interval between frames, for example, each interval is 33ms or 16.6ms, so as to perform packing processing on the debugging data of a forward corresponding time length, which may ensure that the packed debugging data may correspond to image data (acquisition time) according to an index or a timestamp of a data packet, and the AP may distinguish accordingly when performing processing. The debugging data and the image data of the camera can be packed into the same cache register. When the monitoring data and the image data are packed and transmitted, the data need to be split, so that the cache register of the original data can be analyzed and recombined in the pipeline.

For example, in practical applications, when the infringement detection is required, whether the front-end module is virtualized into a video recording device or not can be identified by checking the working state of the camera during use. Furthermore, by determining the size of the data uploaded by the camera module and the output speed (frame rate), if the sizes are consistent within a certain time and the output speed is output at a fixed speed, it can be basically determined that the implementation method provided by the embodiment of the present application is used, and it can be further determined whether infringement is formed.

For example, in practical application, for debugging data transmitted by the front-end module, because the data volume is large, a file can be scanned on a platform side (a mobile phone side), whether large-size data is generated in real time is checked, when the large-size data is detected in real time, the data can be pulled in an adb mode, and then the data content is analyzed, so as to determine whether the debugging data packet is transmitted by the front-end module.

It can be seen that, the data transmission control method described in the embodiments of the present application is used for testing an electronic device, setting a virtual video device, where the virtual video device is configured to encapsulate operating data of a front-end module of the electronic device at a first frame rate, and utilize the virtual video device to package the operating data at a second frame rate to obtain a target data packet, and send the target data packet to a processor, where whether an abnormality exists in the front-end module is determined based at least in part on adjusting a value of the first frame rate and/or the second frame rate.

As shown in the figure 4, fig. 4 is a schematic flowchart of a data transmission control method provided in an embodiment of the present application, and is applied to an electronic device, where the electronic device includes a front-end module and an application processor AP, and the data transmission control method includes:

401. turning on a camera function to invoke a hardware abstraction module, wherein the hardware abstraction module is configured to: for performing unpacking operations.

402. And acquiring target pipeline configuration parameters.

403. And determining a target packaging processing parameter corresponding to the target pipeline configuration parameter according to a mapping relation between preset pipeline configuration parameters and packaging processing parameters.

404. Setting a virtual video device configured to encapsulate operating data of a front-end module of the electronic device at a first frame rate.

405. And packaging the running data according to the target packaging processing parameters by using the virtual video equipment to obtain a target data packet.

406. And sending the target data packet to a processor.

407. And receiving the target data packet through the AP, and copying the target data packet into a target cache register distributed by the USB service in a frame-by-frame mode through the hardware abstraction module.

408. And unpacking the data in the target cache register through the hardware abstraction module to obtain the operating data.

409. And calling a USB service to upload the running data to external equipment through the target cache register so that the external equipment can perform data analysis on the running data.

For the detailed description of the steps 401 to 409, reference may be made to the related description of the data transmission control method described in fig. 3A, and details are not repeated here.

For example, in a specific implementation, the following steps may be performed:

s1, opening a camera;

s2, configuring related customized pipeline configuration parameters and performing resource allocation;

s3, the front-end module configures a packaging mode according to the pipeline configuration parameters, namely, the data size after packaging is ensured to be consistent with the cache register distributed on the AP side;

s4, starting a data stream, acquiring and outputting running data of the module by each sub-module in the front-end module, packaging the data by the MIPI of the front-end module, and rotating a cache register by each module according to set parameters;

s5, the AP receives the data through the hardware abstraction module, analyzes the data according to the data packaging mode, performs copy operation on the analyzed data, and copies the data into the USB service in real time;

s6, the USB service transmits the received data to external equipment;

and S7, rotating the cache register based on the steps to ensure that the monitoring data at the front end is packed in real time and transmitted to the rear end for storage or transmission processing to the PC side.

Furthermore, due to the fact that the MIPI can perform virtual video device processing on the operation data, the operation data can be output to external equipment according to a certain frame rate and size, and then the operation information of the front-end module can be efficiently captured to be analyzed by developers.
