Detailed Description
The term "in-vehicle terminal" in the present invention refers to an electronic device component mounted on a vehicle to acquire in-vehicle image or video data, vehicle driving state data, and/or in-vehicle environment data. The vehicle driving state data may include, but is not limited to, one or more of the following: the position coordinate, the angle, the speed, the angular speed, the steering angle of the front wheel relative to the vehicle body and the battery parameters of the new energy vehicle. In-vehicle environmental data may include, but is not limited to, one or more of the following: temperature and humidity, particulate matter concentration, carbon monoxide concentration, carbon dioxide concentration, and volatile organic matter (formaldehyde, toluene, etc.) concentration. The vehicle-mounted terminal can be used for monitoring petroleum and chemical transport vehicles, public transport vehicles and logistics vehicles.
Fig. 1 shows a block diagram of a vehicle-mounted terminal, which includes a processing device, a sensor, a camera, a communication module, and a display. And according to the actual monitoring requirement, configuring a sensor and acquiring vehicle running state data and/or vehicle internal environment data. The sensor refers to a non-image type sensor, and may include, but is not limited to, one or more of the following monitoring modules: a GNSS positioning module; the device comprises a temperature and humidity sensor, an infrared sensing module, a dust sensor, a formaldehyde, PM2.5, toluene, carbon monoxide or carbon dioxide gas sensor and the like; the monitoring module of the running state of hardware facilities such as air conditioners, engines and the like; vehicle motion information monitoring modules (speed, acceleration, angular acceleration, displacement); angle information monitoring modules (pitch angle, roll angle, azimuth angle); new energy automobile battery information monitoring module. The camera captures image or video data. The sensor establishes physical connection with the processing device through a serial port, and the selectable serial port may include: UART, RS232, RS485, I2C, SPI and USB. The camera can establish physical connection with the processing equipment through a USB interface, an MIPI interface or a DMI interface. The communication module is responsible for the wireless communication connection between the vehicle-mounted terminal and the server and can be connected with the processing equipment through a serial port. The vehicle-mounted terminal has strong mobility due to the fact that the vehicle-mounted terminal moves along with a vehicle, the data volume is small, the transmission frequency is high, and meanwhile long-distance transmission needs to be considered. The invention adopts the transmission mode of cellular communication (4G/5G) to realize remote transmission.
The camera collects video data, the sensor collects vehicle running state data and/or vehicle internal environment data, the vehicle running state and/or vehicle internal environment dynamic changes are displayed and reflected in real time through the displayer, and the displayer is connected with the processing equipment through a VGA (video graphics array), HDMI (high-definition multimedia interface) or USB (universal serial bus) interface.
Functional software of the vehicle-mounted terminal can be developed based on a Linux operating system. As shown in fig. 2, the in-vehicle terminal may include four functional modules: the system comprises a node registration module, a data acquisition module, a data processing module and a data transmission module.
The node registration module realizes the registration function of the vehicle-mounted terminal, mainly comprises an application demonstration theme, a node type, node related meta-information, the number of sensors and meta-data information of each sensor, and randomly generates 8-bit nodeID as the node ID for verifying the vehicle-mounted terminal after registration is finished.
The vehicle-mounted terminal has different requirements on observation perception of vehicle data according to different application demonstration scenes. Therefore, the terminal node registration module needs to include not only the node type and the related information, but also provide a corresponding application demonstration theme so as to facilitate data analysis and make an accurate judgment on the vehicle state. The application demonstration themes mainly comprise a logistics scene, a passenger carrying scene and the like. The logistics scene can be further divided according to the type attributes of goods, such as refrigeration, fragility, flammability and the like.
The sensors have different sampling frequencies, and each data can represent the running state information of the vehicle or the environmental element information in the vehicle in the sampling time. The data acquired by the vehicle-mounted terminal has heterogeneity, the acquired data has different formats and structural characteristics according to different standards, for example, the data acquired by the GNSS positioning module, the temperature and humidity sensor, the gas sensor and the like is semi-structured text information data, and the data acquired by the camera is a real-time video stream and is unstructured data. Therefore, the data acquisition module respectively realizes the acquisition of the semi-structured data and the unstructured data.
And the data processing module performs json format packaging on the acquired semi-structured data according to metadata information, wherein the json format is a lightweight packaging format, and the data processing module is concise and clear in hierarchy and easy to read. And the data processing module adopts H264 video coding for the unstructured video data.
The data transmission module is realized by adopting two process scripts and is divided into two channels for respectively transmitting video data and sensor data. Because the GNSS positioning data, the non-image sensor data and the clock data are semi-structured text data, the transmission of the automobile driving state information and the automobile internal environment data is realized by adopting socket communication programming based on a TCP/IP protocol; the video image data is structured file data, and the RTMP streaming protocol is adopted to carry out video streaming pushing.
The main characteristic of the data collected by the vehicle-mounted terminal is multisource heterogeneity. Considering that the subsequent storage is difficult due to different structural sources of various data, the unified description is carried out on the multi-source data by constructing the metadata dictionary, and the unit or format of the data is normalized. On the basis of the unified description, a data association model is established by using the registered vehicle-mounted terminal node ID, as shown in FIG. 3. And carrying out node registration on the vehicle-mounted terminal to form vehicle-mounted terminal registration information, and ensuring the specificity of the vehicle-mounted terminal deployed in each automobile. And simultaneously registering the vehicle-mounted terminal, registering the mounted sensor and the camera to form sensor and camera registration information. By inquiring the registered node ID of the vehicle-mounted terminal, all sensor and camera information related to the node ID can be inquired. The registered node ID is also added into the sensor data and the video data collected by the sensor and the camera as a label, and the corresponding non-image data and the video data collected by the camera can be inquired through the attribute of the registered node ID, so that the association among the automobile terminal, the sensor and the sensor data and the association among the sensor data and the sensor data are established through the node ID. On the basis, when multi-source heterogeneous data collected by the distributed vehicle-mounted terminals are accessed to a data center of the server side, the data of different vehicle-mounted terminals can be distinguished through the node IDs, and classified storage is carried out according to the data of the vehicle-mounted terminals and information of various sensors registered by the terminals, so that follow-up data query, the automobile driving state and the in-automobile environment can be conveniently and visually reproduced. The invention relates to a method for adding node ID and time labels into data generated by different data sources, which can associate multi-source heterogeneous data and fuse data while ensuring data integrity.
A large amount of semi-structured sensor data and unstructured video stream data acquired by a vehicle-mounted terminal are accessed to a data access management platform of a server side in a multi-path parallel transmission mode. As shown in fig. 4, the server-side system may include four functional modules: the system comprises a log monitoring module, a data access module, a data management module and an in-vehicle environment reproduction module.
The method comprises the steps that non-image sensor data and video data collected by a vehicle-mounted terminal are parallelly accessed to a data layer in an access layer in a unified mode, different data are decoded in the data layer according to coding rules of a client to obtain corresponding data, the data in different formats are classified and packaged, type registration and standardized description are carried out on the sensor data, the data and metadata information of the data are stored in corresponding sets of a database according to storage rules of the database, unified packaging of the data and persistent management of the data are achieved, and corresponding services are provided for users by controlling the persistent data. The invention aims at the characteristics of different heterogeneous data structures, classifies data according to types or application scenes, and combines a database and a file system according to data characteristics so as to overcome the defects of a single storage form and meet the requirements on multi-source heterogeneous data storage.
The whole operation process of the server side is that before a user accesses the server, an access request is sent to the server, after the server receives the access request of the user, whether the request is received or not is judged according to relevant information, if the request is received, the server establishes a service thread for each user, and a special socket port is distributed. Since the data collected by the vehicle-mounted terminal is heterogeneous, a large number of service threads need to be established when massive heterogeneous data is accessed into the system for operation, which causes a high concurrency problem. In order to solve the problem, as shown in fig. 5, a master-slave multithreading mode is adopted on the basis of a netty framework, the mode does not use only a single thread when receiving data acquired by a vehicle-mounted terminal, the single thread is changed into a thread pool, the main thread of the thread pool is only responsible for connection requests, and the auxiliary thread is responsible for allocation of request tasks, so that massive concurrent requests can be processed. The data transmission that will gather of many sensors of deployment in the car is main for receiving the request to main Reactor, and under the condition of only receiving the client request, main Reactor can receive million grades of connection requests, can satisfy the simultaneous access of multichannel sensor in the car, in addition, can also compensate the unstable problem of Reactor thread pool when connecting concurrent request. The main Reactor only receives a connection request of data access transmitted by a vehicle-mounted terminal sensor, the concrete operation of the corresponding request after connection is that tasks are dispatched through the sub Reactor, the sub Reactor dispatches data of the sensor in the vehicle to the thread pool, different types of sensor data are injected into a certain thread in the sub Reactor thread pool, the data transmitted into the thread pool are packaged and encoded through a data format, the thread pool calculates the encoded sensor data, the associated different data are decoded to obtain corresponding vehicle driving state data and vehicle internal environment monitoring data, the heterogeneous data parallel access of various sensors deployed in the vehicle is further realized through a netty frame, and the vehicle driving state data and the vehicle internal environment monitoring data are stored after being successfully accessed into the system.
As shown in fig. 6, for the real-time reproduction requirements of videos in the distributed vehicle, the driving state and the environment in the vehicle, the invention aggregates data collected by different sensors and real-time video stream data transmitted by the vehicle-mounted camera, and visually displays the driving state and the environment in the vehicle on the web page platform according to the query requirements of the user. A user can log in a web webpage platform through a mobile phone or a computer to watch the running state of the automobile and real-time data and videos of the environment in the automobile. The web page platform is built on a web server, the web server interacts with the data server through a local area network to realize the query and feedback of data, and the data is fed back to the intelligent terminal of the user through the Internet. Real-time video stream collected by the vehicle-mounted camera and data measured by the sensor are provided with time empty labels. When a user logs in a webpage to select to view in-vehicle videos, in-vehicle environment data and vehicle running state data, a registered node ID corresponding to a vehicle-mounted terminal of a vehicle is selected, the registered node ID is clicked to play, a camera carried by the vehicle-mounted terminal pushes collected real-time videos to a web server, and the front end of the webpage is pulled to display in-vehicle pictures in real time. The video stream extracts a space-time label from the video stream, and the database searches sensor data which are closest to the video stream in time and space, such as coordinate data, temperature and humidity, gas content and the like according to the node ID and the space-time label registered by the vehicle-mounted terminal of the automobile, so that space-time matching of the real-time video stream, the environment data and the driving state data is realized. And sending the retrieved data to the front end of the webpage, and synchronously displaying the data on a video display page, so that the user can simultaneously see the real-time video in the vehicle and various data measured by the sensor. When the user clicks to stop playing, the camera stops pushing the stream, the webpage stops pulling the stream, the database stops data retrieval, and therefore the webpage stops displaying all data. Therefore, the user clicks playing and stopping to control push streaming and pull streaming of the video, and the bearing pressure of the server can be relieved. According to the invention, the multi-source heterogeneous data are aggregated and the aggregated data are visualized by a multi-source heterogeneous data space-time matching method. The functions of the sensor data and the real-time video stream through the air-space tag matching and synchronous display can well meet the requirements of intelligent logistics on reproduction and real-time monitoring of the environment in the vehicle.
