The new generation of vehicle-road coordination scenarios involves massive devices such as vehicle OBU and roadside RSU, and it is necessary to guarantee secure access to them.
Messaging and service processing in vehicle-road coordination scenarios are highly sensitive to latency. V2X message forwarding needs to solve the low-latency reliable transmission of the vehicle-road message at the ms level.
More specific scenarios of V2X can be realized by solving message coding and decoding of vehicle-road coordination and efficient multi-data streams to coordinate computing capability.
EMQ provides two-level distributed deployment architecture of MEC and Cloud for IoV scenarios. Based on the capability of 5G network slicing, traffic information service with ultra-low latency is realized through nearby access to personal subsystem, vehicle subsystem and roadside unit. Through MQTT, JT808, TCP and other protocols, the information of road conditions perceived by the vehicle and roadside facilities is pushed to the cloud platform, and the intelligent traffic scenarios such as road coordinate perception, safety reminder and remote coordinate control are realized through the cloud control platform combined with V2X algorithm.
It supports international standard TLS/DTLS encryption or national secret algorithm GMSSL encryption, and ensures secure communication of vehicle-road information and coordination by extending authentication system based on PKI/CA certificates.
The powerful rule engine and stream computing engine can realize V2X message processing and real-time triggering of alert events, and analyze the V2X protocol stack through the coding and decoding capability to improve the message processing efficiency of the cloud platform as well.
