The visualization of the Internet of Vehicles promotes the innovation of the intelligent networked vehicle industry

Foreword

Since the end of the 20th century, the automobile era has gone from the mechanical stage, through the electronics and communication stages, to the connected stage and the intelligent stage so far. In the future, cars will realize cognition and autonomous driving.

In recent years, the Internet of Vehicles industry has attracted countless traditional companies, Internet companies, and innovative companies to join the game, and jointly build a new generation of smart cars around "new technologies, new concepts, and new models." The intelligent networked car integrates multiple technologies such as AI, IoT, visual computing, radar, and GPS.

The Internet of Vehicles realizes the intelligentization of people's "second space" cars, and is also a part of the intelligent connection of all things. Cars are no longer cold machines, but intelligent hardware with emotions and warmth. While the Internet of Vehicles promotes the upgrading of automotive products, the evolution of digital technology has also endowed cars with perception and wisdom, allowing cars to evolve from vehicles to intelligent terminals, with the ability to interact and serve.

Today, we will use the HT for Web visualization product independently developed by Hightopo to effectively integrate the upstream and downstream data of the Internet of Vehicles on one screen. Allow urban vehicle operation and maintenance personnel to manage and maintain more intuitively and transparently.

effect display

Using the polygonal presentation map block provided by the HT engine and stitching to achieve the desired effect, it is lighter and faster, and can be completed without modeling, which greatly reduces the implementation cost and cycle. HT also integrates open source solutions to realize the functions of WebGIS in 2D and 3D, which can superimpose various types of map base map data. The unique layout mechanism makes the page adaptive to various screens, and the ratio can be adjusted at will without affecting the picture quality.

The opening chapter is based on a global map, supplemented by animation. Searching for the data visualization of Tupu Internet of Vehicles in the world's vast information, use the longitude and latitude lines to locate Tianjin, click on the 2D panel of Tianjin cloud computing to drill down to the overall three-dimensional scene of Tianjin, and compare the network architecture in the real network space. , Simulate and reproduce the operating status and operating environment of system equipment, business processes.

The 5G base station on the main interface displays the radio waves emitted by the antenna in the form of dynamic water waves. In order to support a flexible networking architecture and adapt to different application scenarios, the 5G wireless access network has many different architectures and different forms of base station equipment. From the perspective of equipment architecture, 5G base stations can be divided into different architectures such as BBU-AAU, CU-DU-AAU, BBU-RRU-Antenna, CU-DU-RRU-Antenna, and integrated gNB. From the perspective of equipment morphology, 5G base stations can be divided into baseband equipment, radio frequency equipment, integrated gNB equipment, and other types of equipment.

The dynamic lines on urban roads represent the shuttle traffic, which echoes the 5G network at the top, showing the context of the Internet of Vehicles. At the bottom left of the interface, there are three buttons that can be clicked: 5G cloud computing, base station information, and traffic information. Operation and maintenance personnel can switch freely and quickly monitor data. Hightopo's visualization products can effectively integrate 2D and 3D images, making the presentation of data more intuitive.

5G calculation

The main goals of 5G are to increase the bandwidth and speed of data transmission, reduce latency, save energy, reduce costs, increase system capacity, and achieve large-scale device connections. 5G uses a series of technological innovations such as high compression density modulation and demodulation, 28GHz millimeter microwave communication, multiple-input multiple-output MIMO phased array antennas, etc., to increase the data transmission speed by a hundred times to 10Gbps.

5G will lead the technological and business innovation of the industrial Internet, and will be deeply integrated with technologies such as the Internet of Things, big data, artificial intelligence, virtual reality, and blockchain. As the new normal and cornerstone of information technology, cloud computing will continue to assume an important technology platform in the 5G era and become the key to enterprise innovation and digital transformation.

The International Organization for Standardization 3GPP has defined three main application scenarios for 5G:

增强移动带宽业务（enhanced Mobile Broadband ，eMBB）

大规模物联网业务（Massive Machine Type Communication，MMTC）

高可靠低延时连接业务（Ultra-Reliable Low-Latency Communication ，URLLC)

Based on this, Hightopo's visualization case is set up on the 5G cloud computing page, with 4 data panels including transmission rate monitoring, security inspection panel, SSL vulnerability distribution, and certificate type, which can access real-time data and perform comprehensive management of network security.

Security check

The operation of the system is simulated by radar scanning, and the image is vivid, and the number of intercepted attacks and the number of days of security protection are displayed eye-catchingly, so that the administrator can know the security of the system.

SSL vulnerability distribution

Show the number of devices affected by CVE. If the impact value soars, protection should be strengthened immediately. The SSL certificate is to comply with the SSL protocol, issued by a trusted digital certificate authority CA, after verifying the identity of the server, with server identity verification and data transmission encryption functions. Since SSL technology has been built into all major browsers and Web server programs, only the server certificate is required to activate this function.

Certificate type

SSL certificates are classified according to different functions and brands, and can be roughly divided into extended verification (EV) SSL certificates, organization verification (OV) SSL certificates, and domain verification (DV) SSL certificates.

A bar chart shows the usage ratio of different types of certificates. Operation and maintenance can popularize the deployment of certain types of certificates according to needs. For example, the EVSSL certificate is issued after strict inspection of its identity by a third-party authority, and the unit name can be displayed directly in the browser address bar, which helps increase the user's sense of security and trust in the website. Its strict inspection of the true identity of the website makes it difficult for criminals to obtain an EVSSL certificate, thereby reducing the risk of users being attacked by phishing websites. In general, DV certificates are only suitable for use in personal websites or test systems. Because of the low security level, it is not recommended for enterprise users to use DV certificates.

With the frequent occurrence of global automotive safety incidents and the continuous emergence of demand for networked functions, safety compliance has become an important prerequisite for enterprise market development, and the overall safety situation of the Internet of Vehicles industry is very severe. We can also adopt the end-to-end security linkage architecture model of vehicle-mounted trusted-level security SDK + roadside intelligent security gateway + security operation platform to build monitoring, detection, early warning, defense, response and emergency response security capabilities, covering the sensing side and transmission Side, platform/application side protection scenarios, escort network security in the field of intelligent transportation.

Base station information

The communication base station is the most critical infrastructure in the mobile communication network. Mobile communication base station room, wires, tower masts and other structural components. The base station room is mainly equipped with signal transceivers, monitoring devices, fire extinguishing devices, power supply equipment and air conditioning equipment. The tower poles include lightning protection and grounding systems, tower bodies, foundations, and supports. The structure of several parts such as cables and auxiliary facilities.

On the basis of static modeling, real-time perception and management are carried out by superimposing multi-dimensional real-time dynamic data. The rotating radar in the upper left corner of the interface scans the location of the base station for easy location management.

Base Station Monitoring System

The device name, power, maximum power, and status are displayed, down to the management of a single device. The base station monitoring system is for remote, real-time, and all-round wireless detection and control of base station power, security, and fire protection. The perfect early warning mechanism realizes multi-level warning, guarantees the reliability of the base station and effectively reduces operation and maintenance costs. The anti-theft detector and the camera are used to realize automatic alarm recording and video upload, and closed management of the entire base station, so as to achieve real-time monitoring and effective management of the base station. It can be remotely monitored through wireless network 5G transmission. The monitoring center (SC) and the monitoring unit (SU) can be connected by a 5G network, and each communication room is equipped with a monitoring unit site to realize single-point-to-multipoint centralized control.

base station signal processing system

The 5G radio frequency unit mainly completes the conversion of NR baseband signals and radio frequency signals and the transceiving and processing functions of NR radio frequency signals. In the downlink direction, the baseband signal from the 5G baseband unit is received, and after upconversion, digital-to-analog conversion, radio frequency modulation, filtering, signal amplification and other transmission link (TX) processing, it is transmitted through the switch and antenna unit. In the upstream direction, the 5G radio frequency unit receives the uplink radio frequency signal through the antenna unit, and after receiving link (RX) processing such as low noise amplifier, filtering, demodulation, etc., it performs analog-to-digital conversion, down-conversion, and conversion to baseband signals and sends them to 5G baseband unit. Stabilize the received signal before sending it out, which can effectively reduce or avoid the loss of the communication signal in wireless transmission and ensure the user's communication quality. Through the event processing rate, it can be determined whether the equipment power is appropriate and whether it needs to be replaced.

Base station signal frequency

It can detect that the frequency of the base station is interfered. It must be considered that the same signal frequency produces co-frequency interference at the same base station or adjacent base stations, and adjacent signal frequencies produce adjacent frequency interference at the same base station. On this basis, base station signal frequency allocation should avoid co-frequency interference and adjacent frequency during communication. interference. If the interference is found in the visualization panel, the frequency can be re-allocated.

traffic information

The speed of infrastructure construction lags behind the growth rate of vehicles. As of March 2021, the number of motor vehicles in the country has reached 378 million; traffic congestion has become a common phenomenon in large and medium-sized cities; the traffic safety situation is severe and the losses caused are huge. The development of smart cars has become a national strategy and a national process. The development of smart cars has long not only emphasized "single-vehicle intelligence", but has promoted the implementation of vehicle-road collaboration.

Intelligent transportation system emerged as the times require. It effectively and comprehensively applies advanced science and technology (information technology, computer technology, data communication technology, sensor technology, electronic control technology, automatic control theory, operations research, artificial intelligence, etc.) to transportation, Service control and vehicle manufacturing strengthen the connection between vehicles, roads, and users, thereby forming a comprehensive transportation system that guarantees safety, improves efficiency, improves the environment, and saves energy.

The realization of intelligent transportation is a systematic project, and the lack of any link may cause "intelligence" but not "ability." For example, to support the upgrade of autonomous driving, in addition to "smart" cars, there must also be "smart" roads. This is inseparable from a vehicle-road collaboration network built up with perceptible infrastructure, data decision-making and management systems. The HT for Web visualization product independently developed by Hightopo presents relevant data to managers to efficiently manage road traffic.

monitoring system

HT 3D visualization technology adopts B/S architecture, lightweight design, and integrates monitoring screens of various road sections through H5 pages. The function of simultaneously monitoring four-channel, eight-channel or sixteen-channel to 64-channel front-end image on the same client terminal is convenient for users to conduct comparative monitoring and global control of the entire monitoring network. When the user clicks on a certain channel of image, it can be zoomed in for real-time monitoring, so that this channel of image appears in the full screen range, which is convenient for the user to observe the details.

Distribution of vehicles in the urban area

Shows the distribution of large, medium, and small vehicles at different times, which can remind citizens to avoid dangerous roads.

Speeding vehicle monitoring

Vehicle sensors convert information about various operating conditions during vehicle operation, such as vehicle speed, temperature of various media, and engine operating conditions, into electrical signals and output to the computer. It can be judged whether the speeding is a car fault or man-made, and take corresponding measures. Through the displayed license plate and the owner's name, the owner can be contacted for criticism and education in time, and the harm can be minimized.

Real-time environmental monitoring

When extreme weather is detected, an early warning can be given. For example, when two major hurricanes hit North America in September 2005, OnStar effectively provided customers with a lot of help during this catastrophic weather, reducing many unnecessary losses. Among the many services provided by OnStar, one is the "Stolen Car Location" service. In other words, once the vehicle is stolen, the OnStar service consultant will assist the police to quickly determine the specific location of the user's stolen vehicle. This technology can help police officers identify car theft criminals, and greatly improve the safety protection coefficient of police officers, road traffic and citizens in the process of hunting down.

event type statistics

Through the histogram and broken line graph, the statistics of vehicle intrusion and abnormal parking are analyzed to analyze whether the configuration of traffic police personnel is reasonable.

Urban traffic conditions

After accessing real-time data, it dynamically displays the traffic conditions of each road in the urban area at different times, and shares the data on the convenience service platform, so that citizens can effectively avoid congested road sections.
