Smart Transportation "Edge Cloud Brain" Solution

Dongtu Technology has launched the "Intelligent Transportation 'Edge Cloud Brain' Solution", which builds a distributed edge cloud brain based on intelligent transportation edge servers to achieve network wide computing and software defined traffic control. Through the collection, processing, release, exchange, analysis and utilization of information, focusing on the intelligent analysis of real-time and short cycle data, edge computing, decentralization, blockchain, traffic adaptive algorithm, two-wire Ethernet bus and other technologies can be used to simultaneously realize diversified services such as traffic signal collaborative control, event driven control, traffic information services, and auxiliary decision-making, while loading various third-party applications and different scenario plans.

1. System features

(1) Improve traffic control efficiency

Based on a networked computing model, the first dynamic computing unit centered around "bottlenecks" can achieve microsecond level clock synchronization and collaborative control across the entire network. The decision of each intersection is related to the information and decision of surrounding intersections, and the traditional central computing and control model is upgraded. edge computing and decentralization technology are used to establish the virtual center of edge cloud network. According to the traffic operation status, congestion points are taken as the center to realize the dynamic collaborative control of the whole network. At the same time, the traffic control process has undergone significant changes from manual optimization to machine learning. Once traffic optimization strategies and goals are set, the edge cloud brain can automatically generate the best solution that meets real-time traffic flow, and achieve real-time monitoring of the operation status of all elements in the entire system, realizing real-time control and closed-loop control.

(2) Reduce construction difficulty and maintenance costs

Based on two-wire Ethernet bus technology, energy supply and network data transmission can be achieved simultaneously on a single cable, realizing intelligent and IP based interconnection of peripheral devices in the transportation field, and constructing an Ethernet based traffic perception and control field network. In terms of construction and operation, we aim to solve the problems of increasing threading, disorderly wiring, and difficulty in locating faults, in order to reduce construction difficulty and operation costs. Simultaneously connect IP to intelligent devices to achieve multi network integration.

(3) Adapt to the future development of vehicle road collaboration

The edge cloud brain system has V2X vehicle road collaboration function, and HOUSSIS high-performance processing capability realizes comprehensive decision-making of road network information and real-time interaction of vehicle road information. The industrial grade network bus has a complete network and data security mechanism to ensure the safety, real-time, and reliability of vehicle road information exchange.

(4) Meet the needs of future smart city development

The "Edge Cloud Brain" solution can not only manage urban traffic, but also expand various applications based on artificial intelligence, extending from traffic management to smart city governance, serving smart city operations such as urban IoT access, key scene area control, vehicle and personnel positioning and tracking, urban public safety, and traffic emergency command. In the future, the "edge cloud brain" will become the basic unit of smart cities, serving as a carrier platform for software defined urban functions, and helping city managers embrace new opportunities brought by new technologies such as autonomous driving and the Internet of Things.

2. Cost advantage

HOURISIS Server intelligent transportation edge server is an integrated product that integrates access, computing, storage, network, security, and services. It realizes regional adaptive control at the edge without the need for a central platform to issue solutions. At the same time, the product comes with industrial grade switches, which can save construction costs such as central control platforms and deployment servers, central computer rooms, command centers, intersection to center communication, road network switches, etc. Taking the construction of five intersections as an example, the construction cost is one fourth of the traditional construction mode.

3. Application Cases

The product has been applied in multiple provinces and cities including Nansha in Guangzhou, Yichang in Hubei, Shijingshan in Beijing, and Haidian. It has achieved functions such as adaptive intersection, bidirectional green wave, queue overflow, and special duty control.
