Vehicle information wireless collection method based on Internet of Vehicles

Abstract

The invention provides a vehicle information wireless collection method based on an Internet of Vehicles. The method comprises the steps of establishing a vehicle internal wireless sensor network between a terminal sensor node and a WSN coordinator through IEEE 802.15.4 wireless communication; the WSN coordinator receives data information sent by the terminal sensor node through a wireless network and transmits the data information to a monitoring master platform through a serial port, thereby finishing collecting and transmitting internal signals of a motor vehicle. According to the vehicle information wireless collection method based on the Internet of Vehicles, the reliability and timeliness in the wireless transmission process of the data are improved; the power consumption of the node is reduced; the life cycle of the network is prolonged; and reliable wireless data transmission is realized under a complicated electromagnetic environment in the vehicle.

Description

technical field [0001] The invention relates to information sensing and collection, in particular to a method for wireless collection of vehicle information based on the Internet of Vehicles. Background technique [0002] In recent years, my country's motor vehicle consumption demand has been strong, the process of motorization has been accelerating, and the annual production and ownership of domestic motor vehicles have continued to grow rapidly. Users have higher and higher requirements on the performance of motor vehicles, followed by the continuous improvement of related detection technologies for motor vehicles. At present, there are two methods for motor vehicle performance testing. One is the standard motor vehicle testing line for routine vehicle performance testing and safety testing, which requires a larger testing space and more testing equipment. The other is a portable on-board test equipment used for vehicle road testing that directly reflects the real-time co...

AI Technical Summary

Problems solved by technology

For the application of wireless sensor technology in vehicle testing, most of the wireless sensor networks built by various manufacturers currently use high-power RF modules, and no unified development and design standards have been formed, which increases the difficulty of development and later maintenance costs.
