A method and device for pushing business data of an Internet of Vehicles device gateway

Abstract

Embodiments of the present invention provide a method and device for pushing business data of a gateway service of an Internet of Vehicles device. The method includes: establishing a link between the Internet of Vehicles device and the data receiving thread; using the data receiving thread group to receive the The business data sent by the Internet of Vehicles device; the business data is sent to the data push thread group through the double buffer module; the business data is pushed to the distributed publish and subscribe by using the data push thread group message system, thereby avoiding the shocking phenomenon of the data receiving thread group caused by the vehicle network device when the connection is established with the gateway. Further, it also avoids the delay in a certain link in the process of connecting the vehicle network device to the gateway The jitter affects the entire process processing. Furthermore, it also avoids the use of locks between thread groups to exchange data, speeds up the process processing speed, and thus improves the processing speed of a single gateway, reducing the manufacturing cost of the Internet of Vehicles.

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. [0003] With the rap...

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
