Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
It is noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of the present application and in the foregoing figures, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server comprising a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
Referring to fig. 1, fig. 1 is a schematic diagram of an application scenario of a data playing method according to an embodiment of the present application, where, as shown in fig. 1, the application scenario includes a perception layer 101, a decision layer 102, and an execution layer 103. The application scene is in an automatic driving automobile or an intelligent driving automobile. The perception layer 01 completes the identification of external environment information by receiving data, analyzing the data and playing the data, wherein the data playing function is realized by the data playing method in the embodiment of the application. The information receiving devices of the sensing layer 101 include environment sensing devices such as cameras, laser radars, ultrasonic radars and millimeter wave radars for receiving external information, and devices for assisting in vehicle positioning such as high-precision maps, inertial navigation, global satellite positioning and vehicle-to-external information exchange (vehicle to everything, V2X). The decision layer 102 plays a role in performing information fusion and analysis processing on the information data acquired from the perception layer 101, and converts useful external information into execution instructions, such as track path planning and processing of abnormal situations. The execution layer 103 performs corresponding operations, such as steering control, driving control and braking control, on the vehicle according to the instruction provided by the decision layer 102, so as to realize automatic driving of the vehicle. It can be seen that the efficiency of playing data in the perception layer 101 is important, and directly related to the efficiency of the subsequent decision layer 102 and the execution layer 103, thereby affecting the efficiency of automatic driving.
In this embodiment of the present application, a specific application scenario of the data playing method is the perception layer 101. In the sensing layer 101, data received from a camera, a laser radar, an ultrasonic radar, a millimeter wave radar, and the like are complicated, and the amount of data is large, and data analysis and data playback by an external tool are required. The current tool layer for analyzing and playing the data is endless, but a lot of inconveniences still exist in the process of playing the analyzed data. The current tool stores the data into the offline file, and then guides the offline file into analysis software for analysis, so that online data receiving, analysis and playing cannot be completed, and the efficiency is low. The online playing data is real-time playing, the system receives new data while analyzing the received data, analyzes the new data while playing the analyzed data, and the receiving data, the analyzing data and the playing data are continuously carried out, so that the online playing can realize faster and more timely playing of the data. Accordingly, the online playing technology has higher requirements on the system, and the system is required to support the rapid processing of a large amount of data to complete the data synchronization and the data playing; if the system cannot meet the performance requirement, the problems of data analysis errors, data playing clamping and the like are caused, namely, online data playing cannot be achieved. If the system performance is improved according to the requirement of playing the data online, the system becomes more complex and the cost is higher. At present, due to the requirements of environmental protection and energy conservation, the light weight of equipment has become the trend of world automobile development; in order to meet the light weight of equipment, the requirement of playing data online can be met by improving a data playing method.
Embodiments of the present application parse and play data via a data abstraction service (Data Abstract Service, DAS) tool based on the data distribution service (Data Distribution Service, DDS) protocol. The DDS is a new generation of distributed real-time communication middleware protocol, adopts a publish/subscribe system architecture, emphasizes the centering of data, provides rich service quality (Quality of Service, qoS) strategies, ensures the real-time, efficient and flexible distribution of data, and can meet the application requirements of various distributed real-time communication. In DDS, users only concern about the data that they want, the data is identified by Topic (Topic), publishers publish data according to Topic, subscribers subscribe data according to Topic that they are interested in. That is, the DDS can fulfill the data receiving requirement in the sensing layer 101, and the DAS tool performs data parsing and data playing on the data received by the DDS.
Referring to fig. 2, fig. 2 is an exemplary diagram of a functional module of a DAS tool provided in an embodiment of the present application, and as shown in fig. 2, the functional module of the DAS tool includes a data processing module 201 and a data display module 202, which are respectively configured to perform data analysis and data playing on data received through a DDS.
Fig. 3 is a flowchart of a data playing method according to an embodiment of the present application, as shown in fig. 3, the data playing method may be applied to an automobile with light equipment, and includes the following steps:
s301: the received first data is stored to a first buffer database of the double buffer databases.
S302: in the first data storage process, if the residual capacity in the first buffer database meets the preset capacity, copying the first data in the first buffer database to a second buffer database in the double buffer database to obtain second data in the second buffer database.
In this embodiment, the data processing module 201 in the DAS tool parses the information received from the information receiving device in the sense layer 101 and converts the parsed information into the first data that can be displayed in the data display module 202 in the DAS tool. In order to prevent the phenomenon of software blocking in the process of playing data, the DAS tool adopts a double-buffer storage mode to store the data into a double-buffer database in the process of storing the first data, wherein the double-buffer database comprises a first buffer database and a second buffer database. In the single buffer storage mode commonly used before the double buffer storage mode appears, only one buffer area is stored in the database, and the data is updated and the data to be displayed is prepared in the buffer area; after the data is updated, the data to be displayed can be displayed through the display device, so that the problems of flickering, tearing and the like can be easily caused in the refreshing process of the data playing. In the double-buffer storage mode, two buffer areas are arranged in the storage database, updated data are continuously stored in the rear buffer area (namely the first buffer database in the embodiment of the application), and when the updated data in the rear buffer area reach a certain capacity, the updated data are copied to the front buffer area (namely the second buffer database in the embodiment of the application) and then displayed through the display device; in the whole process, the updating and the displaying of the data can be performed simultaneously, so that the fluency of the data playing is greatly improved. Compared with the single buffer storage mode, the double buffer storage mode has complex program, but has high efficiency, can improve the fluency of data playing, and solves the possible phenomena of data blocking and software blocking in online playing.
In an alternative embodiment, when the preset capacity of the remaining capacity in the first buffer database is 0 or other preset capacity smaller than the total capacity of the first buffer database, the first data in the first buffer database is copied to the second buffer database, so as to obtain the second data. The DAS tool automatically deletes the copied first data in the first buffer database after completing the conversion of the first data and the second data according to the program setting, and the preset capacity of the residual capacity in the first buffer database is kept unchanged, so that the conversion process of the first data and the second data is continuously performed. The data is deleted in time, so that the capacity of a storage database can be reduced, the efficiency is improved, and the lightweight design of equipment is facilitated.
In another alternative embodiment, when the preset capacity of the remaining capacity in the first buffer database is 0 or other preset capacity smaller than the total capacity of the first buffer database, the first data in the first buffer database is copied to the second buffer database, so as to obtain the second data. The DAS tool temporarily retains the copied first data in the first buffer database after completing the conversion of the first data and the second data according to the program setting, appropriately changes the preset capacity of the residual capacity in the first buffer database, and deletes the copied first data in batches after reaching a certain capacity, so that the conversion process of the first data and the second data is continuously performed. Data is temporarily reserved, occurrence of unexpected situations can be effectively prevented, and data security is improved; after a period of time, the data is deleted, so that the capacity of the storage database can be reduced to a certain extent, the efficiency is improved, and the lightweight design of equipment is facilitated.
S303: performing block processing on the second data based on the equipment type and time to obtain a data set to be displayed; the data set to be displayed comprises data to be displayed corresponding to different devices in different time periods.
In the embodiment of the application, the second data is subjected to block processing based on the device type to obtain data to be displayed of a plurality of topics (Topic), such as Topic 1, topic 2 and Topic 3; and performing further blocking processing on the second data based on the time length to obtain data to be displayed of a plurality of themes (Topic), wherein each Topic comprises the data to be displayed of the same time length, for example, the data in Topic 1 are divided into Topic 1.1, topic 1.2 and Topic 1.3. The data set to be displayed comprises data to be displayed corresponding to different devices in different time periods, and the data set to be displayed is located in a data display module 202 in the DAS tool. According to the method and the device, based on equipment and time, the target data are played in different topics, the problems of software blocking and low data playing efficiency caused by overlarge data quantity are solved, and the data playing efficiency is improved.
In an alternative embodiment, after the second data is subjected to the blocking processing based on the device type, further blocking processing may be performed on the second data based on the size of the data capacity, so as to obtain data to be displayed of multiple topics (Topic), where each Topic includes data to be displayed of the same size. The second data is partitioned based on the equipment and the data capacity, so that the problems of software blocking and low data playing efficiency caused by overlarge data volume can be solved, and the data playing efficiency is improved.
S304: displaying target data in response to a data display instruction for the target data; the data set to be displayed includes target data.
In the embodiment of the application, the DAS tool responds to the data display instruction for the target data, selects the target data corresponding to Topic and displays the data. The target data is located in a set of data to be displayed in a data display module 202 in the DAS tool.
In this embodiment, before step S301, the data playing method further includes obtaining first data. Fig. 4 is a flowchart of a method for acquiring first data according to an embodiment of the present application, where, as shown in fig. 4, the method for acquiring first data includes the following steps:
s401: acquiring third data;
in this embodiment, the third data is information data directly received in real time by the information receiving device in the sensing layer 101, such as data received by a camera, a laser radar, an ultrasonic radar, a millimeter wave radar, and the like.
In an alternative embodiment, the third data is not directly derived from the data received by the information receiving device in real time, but is data that is stored after the information receiving device receives the data, such as data stored in an offline file or a removable storage device. In this case, the third data may be derived from a lightweight car of a device using the data playback method, or may be derived from another car.
S402: and packaging the third data to obtain fourth data to be analyzed.
In this embodiment of the present application, due to the difference in data formats, the data processing module 201 in the functional module of the DAS tool encapsulates the third data, and converts the format of the third data into a format that can be used for data parsing, that is, the fourth data. Due to the difference of the information receiving devices, the data types of different topics, such as can data, struct data and proto data, are obtained.
S403: and analyzing the fourth data to obtain fifth data.
In the embodiment of the present application, in the data parsing process, the data processing module 201 establishes a mapping relationship between data types of different topics corresponding to different information receiving devices and different parsing modules, and parses the data types of the different topics through the different parsing modules, so as to obtain parsed fifth data. Wherein can data passes through the DBC analysis module, struct data passes through the struct analysis module, and proto data passes through the proto analysis module.
In an alternative embodiment, the parsed fifth data is recorded and analyzed, and the fifth data may be modified according to the analysis result, so as to optimize the data. The modified fifth data becomes new third data, and the operation from step S401 is continued.
S404: and converting the format of the fifth data to obtain the first data to be displayed.
In this embodiment of the present application, due to the difference in data formats, the data processing module 201 in the functional module of the DAS tool performs format conversion on the fifth data, and converts the format of the fifth data into a format that can be displayed in the data display module 202, that is, the first data. Also, in this process, format conversion is performed by using a format conversion module corresponding to data types (can data, struct data, proto data).
In this embodiment, after step S304, the data playing method further includes offline playing data, that is, transferring the target data to an offline database; displaying target data in response to a data display instruction for the target data; the display is an offline display. In the online broadcasting display data, the system receives new data while analyzing the received data, analyzes the new data while playing the analyzed data, and the receiving data, the analyzing data and the playing data are continuously performed; in contrast, the offline display of data only plays the data. The target data already stored in the offline database is displayed offline at any time as needed.
In some possible embodiments, the data display instructions include first data display instructions displayed in tabular form. In step S304, the target data is displayed in a tabular form in response to the first data display instruction for the target data. The data set to be displayed comprises device-based, time-based (or data volume) target data for different topics. Fig. 5 is a schematic diagram of a display interface for displaying target data in a table format, where, as shown in fig. 5, according to a first data display instruction, a specific Topic is selected from a left Topic list, and then the target data can be played in a right table display area. The table may display target data of one data type (selected Topic) or target data of multiple data types (based on more refined Topic of the selected Topic, such as Topic 1.1 including Topic 1.1.1 and Topic 1.1.2) simultaneously. The horizontal header of the table represents the data type, the vertical header of the table represents the time, and the table corresponding to a certain time and a certain data type is the target data of the time and the data type. In either an online or offline state, the target data may be displayed in tabular form. When playing data online, the form can automatically move down and automatically update the playing target data according to the time information without mouse operation; the mouse can be dragged up and down to play the target data. When the data is played offline, the mouse can be dragged up and down to play the target data. According to the method and the device, based on equipment and time (or data volume), the target data are played in different Topic modes, the problem that data playing efficiency is low due to overlarge data volume of the table is solved, and the data playing efficiency is improved.
In some possible embodiments, the data display instructions include second data display instructions that are displayed in graphical form. In step S304, the target data is displayed in a graphic form in response to the second data display instruction for the target data. The data set to be displayed comprises device-based, time-based (or data volume) target data for different topics. Fig. 6 is a schematic diagram of a display interface for displaying target data in a graphic form, as shown in fig. 6, according to a second data display instruction, a Topic is selected from a Topic list on the left side, and the target data can be played in a graphic display area on the right side. With respect to the table, the graph can only display the target data of one data type (selected Topic), the horizontal axis of the graph represents time, the vertical axis of the graph represents data of a certain data type, and the target data corresponding to a certain time can be determined in the graph. The target data may be displayed in graphical form, either online or offline. When the data is played online, the graph can automatically and continuously update and play the latest displayed target data from right to left according to the time information without mouse operation; the mouse can be dragged left and right to play the target data. When the data is played offline, the mouse can be dragged left and right to play the target data. According to the method and the device, based on equipment and time (or data volume), the target data are played in different Topic modes, the problems of software blocking and low data playing efficiency caused by overlarge graphic data volume are solved, and the data playing efficiency is improved.
In some possible embodiments, the second data display instructions include third data display instructions that indicate display in a waveform diagram. In step S304, the target data is displayed in the form of a waveform diagram in response to the third data display instruction for the target data. Fig. 7 is a schematic diagram of a second display interface for graphically displaying target data according to an embodiment of the present application, where, as shown in fig. 7, a waveform chart includes at least one time-value calibration control 701. The time value calibration control 701 can move left and right in the waveform diagram, and when the time value calibration control 701 stays at a certain moment, the target data corresponding to the moment can be displayed. When the data at a certain moment is required to be acquired, a time value calibration control 701 is selected, and the time value calibration control 701 is dragged to the moment, so that the data corresponding to the moment can be displayed in real time on the ruler line toolbar; when the data range of a certain time period needs to be acquired, two time value calibration controls 701 are selected, and the two time value calibration controls 701 are dragged to the starting time and the ending time of the time period respectively, so that the difference value between the data corresponding to the two time value calibration controls 701 can be displayed in real time on the ruler line toolbar. In this embodiment of the present application, the target data corresponding to a certain time and the data range within a certain time period may be conveniently and accurately obtained through the time value calibration control 701.
In some possible embodiments, the data playback method further comprises receiving a time inquiry instruction, the time inquiry instruction comprising at least one data value. If the value corresponding to the target data displayed in the waveform pattern includes the data value, the control time value calibration control 701 is moved to the position corresponding to the data value, where the position is the position included in the waveform pattern. That is, if a certain data value in the time inquiry command is also a value corresponding to the target data in the waveform diagram, after receiving the time inquiry command of the data value, at least one time value calibration control 701 in the waveform diagram moves to a position corresponding to the data value in the waveform diagram, and displays the moment corresponding to the data value in real time in the ruler line toolbar. And if the two data values in the time inquiry command are both data values corresponding to the target data in the waveform diagram, after the time inquiry command of the two data values is received, at least two time value calibration controls in the waveform diagram can be moved to positions corresponding to the data values in the waveform diagram, and the difference between the moments corresponding to the two data values is displayed in real time in the ruler line toolbar. Since there may be a case where the same data value corresponds to a plurality of times in the waveform diagram, a plurality of results may occur when a time corresponding to a certain data value is queried by the time query command. In this case, the appropriate result is selected as needed in the process of analyzing the displayed data. In the embodiment of the application, the time corresponding to a certain data value and the time period corresponding to a certain data value range can be conveniently and accurately obtained through the time inquiry instruction.
In the embodiment of the application, in an online or offline state, the data playing method can play the target data in a form of a table and a graphic, can manually play the target data in a dragging mode, and can automatically play the target data in a scrolling mode. In addition, in the target data in the form of a waveform diagram, the target data corresponding to a certain time and the data range in a certain time period can be conveniently and accurately obtained through the time value calibration control 701, and the time corresponding to a certain data value and the time period corresponding to a certain data value range can also be conveniently and accurately obtained through the time query instruction. Therefore, the data can be acquired more conveniently, quickly and intuitively by the data playing method, so that existing data can be analyzed more accurately and quickly by a research and development or test engineer in the field of automatic driving or intelligent driving, and vehicle system algorithm optimization or product verification can be carried out.
