According to Japanese media reports, the East Japan Expressway Corporation (NEXCO East Japan) stated that using the quasi-zenith satellite “Guide” technology, it will realize the practical application of the snow removal vehicle automatic driving system as early as 2023, without the use of cameras. Snow plows can drive with an error of less than 20 cm in snowy days with poor visibility.

The quasi-zenith satellite “Guide” is known as the Japanese version of the Global Positioning System (GPS), and many Japanese companies currently hope to use this technology to achieve autonomous driving. According to reports, only using GPS will produce an error of several meters, but if the “Guide” number is used, the minimum positioning information error is only a few centimeters, no steering wheel is required, and snow removal vehicles with a width of more than 2 meters can basically drive automatically on the envisaged route. During snow removal operations on the highway, the snow removal vehicle will not deviate from the white line of the road, nor will it touch the roadside guardrail.

The first satellite was launched in 2010, and it was developed by Mitsubishi Electric and also operated by Nippon Electric Co., Ltd. NEC. In 2017, 3 satellites will be added, and the current 4 satellites will be operated by 2018. “With the increase in the number of applications, the driving stability has also been improved.” Abe Katsuyoshi said.

NEXCO East Japan confirmed the performance of the autonomous driving technology with the help of the signal of the “Guide” in the test in 2021, and strives to complete the system in 2022 and the Iwamizawa-Bibai Interchange (IC) in Hokkaido by 2023. Get started.

In the field of passenger cars, some autonomous driving and driving assistance technologies that use the “Guide” positioning information have been put into practical use. For example, Nissan’s pure electric vehicle “Ariya” supports positioning information with an error of only a few centimeters, Subaru (SUBARU) and Honda Some of the models will also use the “Guide” number.

In order to provide stable location information, the Japanese government plans to increase the number of “Guide” satellites, which will be increased from the current 4 satellites to 7 around 2023. It is expected to operate alone without relying on US GPS.

The vehicle operation monitoring system has long been the focus of the development of intelligent public transportation. Internationally, systems such as IVHS in the United States and VICS in Japan have realized the management and information services of intelligent public transportation by establishing effective information communication between vehicles and roads. And 3G/4G and other wireless technologies have also been applied in the intelligent management of transportation, such as intelligent bus positioning management and signal priority, operation scheduling management, real-time vehicle status and environmental information collection, etc. have achieved certain application results.

Under the background of the development of communication through science and technology, the transportation industry is undergoing an unprecedented major transformation. Traditional manual scheduling, semi-automatic scheduling, and pure GPS/BD scheduling will gradually be replaced by intelligent scheduling. The wide application of big data mining technologies based on the Internet of Vehicles and OBD can not only change the function and informatization degree of in-vehicle video terminals, and form an emerging industry, but will also innovate transportation management and service methods, and help the transformation and upgrading of the transportation industry. play an important supporting role.

In the construction of intelligent transportation system, “high-definition” has become an inevitable development trend. The entire video surveillance system has been transformed from a “visible” video security system to a “clearly seen” high-definition networking system, and following the principle of “build for use, use for war”, the intelligentization of “see clearly” has begun. , System construction of business integration applications.

High-definition is not only the application of a single high-definition technology, but starts from the actual business application requirements of intelligent transportation, which can adapt to the needs of all cities in the city to control the high-definition image quality. The control surface of the entire city is in a complex and diverse application “ecological environment”. Therefore, the construction of high-definition intelligent transportation systems needs to choose suitable high-definition solutions according to the different characteristics of different application scenarios. High-definition vehicle video recording is bound to be the future. a development direction.

Due to the large amount of car video data and limited local storage space, in order to completely back up all the video, we must use cloud storage.

Cloud storage is a new concept extended and developed from the concept of cloud computing. A system that works together through application software to provide data storage and business access functions to the outside world. Cloud storage is a cloud computing system with data storage and management as its core. Simply put, cloud storage is an emerging solution to put stored video resources on the cloud for human access. Users can connect to the cloud through any networkable device at any time, anywhere, and access data conveniently. The advantages are as follows:

Cost saving: The biggest feature of cloud storage in the short and long term is that it can reduce costs.

Better backup of local data and remote processing of daily data: In the previous storage system management of on-board terminals, managers needed to face different storage devices, and devices from different manufacturers had different management interfaces, which made managers need to understand each The work of the usage status (capacity, load, etc.) of each storage medium is complex and heavy. Moreover, in the vehicle vibration environment, the traditional storage medium hard disk is easily damaged, resulting in data loss, while cloud storage does not. If the hard disk is damaged, the data will be automatically migrated to other hard disks, which greatly reduces the work of management personnel burden.

With the rapid development of technology, the vehicle video surveillance system is also constantly developing, bringing a more convenient experience for managers. Combined with the characteristic needs of the industry, it creates a more intimate industry application for users.

The residual heat of Wi-Fi6 has not dissipated, and Wi-Fi7 has become a new hot topic that has been discussed a lot in the industry recently. More and more manufacturers have entered the game, and the commercialization of Wi-Fi 7 seems to be coming soon. Recently, Qualcomm released the Wi-Fi7 networking solution, and said that the Wi-Fi7 chip has been shipped to customers, and the terminal products are expected to be launched before the end of this year. It is expected that the Wi-Fi7 penetration rate will reach 10% from 2023 to 2024.

After the emergence of 5G and gigabit optical broadband, the applications of online video conferencing, remote office, cloud computing, ultra-high-definition (3D) video, augmented reality, and virtual reality have also quietly approached our lives, and also meet the needs of the Internet of Vehicles, Smart home, industrial control, environmental monitoring, mobile medical and other IoT application requirements. Compared with 5G mobile communication technology, Wi-Fi6 wireless network technology has also accelerated its sinking into industrial IoT applications.

With the rapid development of WLAN technology, families and enterprises are increasingly relying on Wi-Fi as an important means of accessing the network. A few days ago, the Wi-Fi Alliance created a wireless local area network technology based on the IEEE 802.11 standard, namely Wi-Fi6, and allows it to communicate with up to 8 devices at a maximum rate of 9.6Gbps. In January 2022, the Wi-Fi Alliance announced the Wi-Fi 6 version 2 standard.

It is understood that the Wi-Fi 6 version 2 standard improves the uplink and power management of all supported frequency bands (2.4GHz, 5GHz and 6GHz) and is suitable for routers and devices in the home and workplace, as well as smart home IoT devices. In general, compared with previous generations of WiFi technology, the new generation of Wi-Fi 6 has the advantages of faster speed, lower latency, larger capacity, more security, and more power saving.

Even so, due to the increasingly high throughput and latency requirements of new scene applications, such as 4K and 8K video (the transmission rate may reach 20Gbps), immersive AR/VR, real-time collaboration, wireless games (low latency requirements) 5ms), telecommuting, online video conferencing and cloud computing, etc., the new generation of WiFi6 still cannot fully meet the demand. In response to this, the IEEE 802.11 standards organization expects to release a new revised standard IEEE 802.11be EHT, namely Wi-Fi 7, by the end of 2022.

WiFi7 has the characteristics of high network throughput, low latency, high transmission volume, high reliability, and high stability, which can greatly improve the networking performance, which is very important for various experiences of future applications in new scenarios. Based on this, the three major chip manufacturers Qualcomm, MediaTek, and Broadcom are sparing no effort to promote the development of Wi-Fi 7. For example, Qualcomm said that Wi-Fi7 chips have already started shipping at this stage, and terminal products are expected to be available before the end of this year, and will be shipped in large quantities in 2023.

MediaTek released Wi-Fi7 chips, Filogic880 and Filicic380, which provide industry-leading router and gateway solutions for high-bandwidth applications in the carrier, retail, commercial and consumer electronics markets. At the 2022 Mobile World Congress, Qualcomm released the 14nm chip FastConnect7800 that supports Wi-Fi7 and Bluetooth 5.3. ZTE also showed the world’s first Wi-Fi7 terminal MC888 Flagship in the form of CPE (Customer Premises Equipment).

In the era of the Internet of Things, whether it is 5G mobile communication technology or Wi-Fi technology, it is closely related to production and life. From consumer electronics, industry, automobiles, to smart homes and other fields, Wi-Fi technology can be seen everywhere and contains very large development potential. As more and more manufacturers enter the game and preempt the pit, will Wi-Fi7 land and multi-scenario integrated applications such as edge computing, metaverse, extended reality (XR), remote office, and social games still be far behind?
