Internet of vehicles device gateway business data pushing method and device

Abstract

The embodiment of the invention provides an Internet of vehicles device gateway business data pushing method and device. The method comprises the steps of establishing links between Internet of vehicles devices and data receiving threads; receiving business data sent by the Internet of vehicles devices through adoption of a data receiving thread group; sending the business data to a data pushing thread group through a double-buffer module; and pushing the business data to a distributed issuing and subscription message system through adoption of the data pushing thread group. The thundering herd occurs in the data receiving thread group resulting from the fact that the Internet of vehicles devices access a gateway and establish the links is avoided, further, in a process of accessing the gateway by the Internet of vehicles devices, the fact that the whole flow processing is influenced when delay jitter occurs in certain step is also avoided, further the fact that the data exchange is realized through locks between thread groups is also avoided, the flow processing speed is accelerated, the processing speed of the single gateway is improved, and the production cost of the Internet ofvehicles is reduced.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a method for pushing service data of an Internet of Vehicles device gateway and a device for pushing service data of a Internet of Vehicles device gateway. Background technique [0002] The Internet of Vehicles (Internet of Vehicles) is a huge interactive network composed of information such as vehicle location, speed and route. Through GPS, RFID, sensors, camera image processing and other devices, vehicles can complete the collection of their own environment and state information; through Internet technology, all vehicles can transmit and gather their own various information to the central processing unit; through computer technology, these Information from a large number of vehicles can be analyzed and processed to calculate optimal routes for different vehicles, report road conditions in a timely manner, and arrange signal light cycles.

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of the Internet of Vehicles, a large number of Internet of Vehicles devices put a lot of pressure on the gateway when they are connected to the gateway. To forward the data to the distributed publish-subscribe message system, if a single thread is used to complete the entire data transmission process, any delay in any link will affect the processing speed of the entire data transmission process, and when a large number of terminal devices access the gateway At the same time, although the access pressure of a single gateway can be dispersed by using LVS to horizontally expand the cluster of gateways, if the processing speed of a single gateway is not increased, the number of clusters cannot be reduced, which will eventually lead to a very high cost of the Internet of Vehicles
