Abstract

The invention provides a method for transmitting state data of a motor vehicle in real time. The method comprises the following steps: transmitting state data acquired by a vehicle-mounted sensor to a router and a WSN (Wireless Sensor Network) coordinator through an IEEE 802.15.4 wireless channel; performing data reduction in a transmission process; performing analytical calculation on the data according to an information type to obtain an optimal reduction result; and transmitting an optimal value to a main monitoring platform through serial port communication. Through adoption of the method for transmitting the state data of the motor vehicle in real time, the reliability and real-time performance of the data in a wireless transmission process are improved; the node power consumption is lowered; the network life cycle is prolonged; and reliable wireless data transmission is realized finally under a complex electromagnetic environment inside the vehicle.

Description

technical field [0001] The invention relates to information sensing and collection, in particular to a method for real-time transmission of motor vehicle state data. 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 conditions of the vehicle du...
