As a scenario where autonomous driving technology is easier to implement, since 2017, many provinces and cities have piloted unmanned sweepers to save human resources. However, in the actual cleaning process, in addition to identifying vehicles, pedestrians, traffic lights and other routine recognition content of autonomous driving, it is also necessary to identify ground garbage, roadside branches, water pipes, stones, potholes, and safely avoid obstacles in real time.
So, how can unmanned sweepers achieve obstacle avoidance through remote control? What is the range of remote control command delay that needs to be controlled to ensure the safe driving of the vehicle? Agora Network, a leading enterprise in emerging industries that has developed and grown in Yangpu KIC World, gave the answer.
By providing a low-latency, low-lag, and highly reliable parallel control solution, Agora helps vehicles get out of trouble remotely.
In terms of audio transmission, the end-to-end delay of Agora is as low as 100ms, and the 95th percentile is 180ms. 60% anti-weak network packet loss boundary, measured 100ms jamming rate during stable operation 001%；Under 20% packet loss + 50ms network jitter, the 100ms lag rate is 01%。At the same time, relying on the SD-RTN developed by Agora Network, it can ensure that the real-time signaling transmission has a message arrival rate of 100% in the case of 70% packet loss, which greatly improves the safety of unmanned sweepers.
In order to improve the efficiency of operations, many enterprises will manage multiple unmanned sweepers at the same time in the background, and in the case of high signaling concurrency, the RTM and audio ** of Agora can support unlimited concurrency, support more than 100 billion message concurrency, and support 1 million concurrency in a single channel. On the operating side, Agora's RTM solution supports mainstream in-vehicle systems Linux and Android, and the control end supports Linux, Android, Web, Windows, iOS, Mac and other platforms.
Not only that, self-driving sweeper companies will also launch operation and maintenance centers in foreign countries such as the Middle East and Europe, while in overseas areas, the audio + signaling transmission often encounters difficulties such as no edge node coverage and weak network jamming, which will directly lead to serious problems such as service unavailability and vehicle safety inability for technical scenarios with high real-time accuracy requirements for unmanned sweepers.
Agora Parallel Control Solution is deployed at global nodes, providing high-quality real-time cloud signaling services covering more than 200 countries and regions around the world, achieving a global end-to-end median latency of 76ms, with excellent anti-weak network capabilities, and meeting the business needs of enterprises with low latency and high accuracy for remotely controlled sweepers worldwide.
In addition, Agora's parallel control solution can also be used in business scenarios such as emergency takeover, high-risk operations, and remote services. First of all, emergency takeover, taking unmanned vehicles as an example, unmanned vehicles are currently widely used in airports, docks, ports and other places, but in the application process, there are often some scenarios that cannot make independent decisions, such as storms, traffic control, and accidents. Compared to the previous need for human intervention in the field, parallel control can solve this problem faster and at a lower cost. Parallel control can also play a good role in high-risk work scenarios such as underground mining trucks, aerial work robots, and unmanned excavators, such as high danger index or harsh environments. Remote services, such as robots, cloud racing, drones, and other scenarios, operators can use cloud services to control these unattended devices.
