Abstract

The invention discloses a multi-protocol switching method and device based on data transmission, and is applied to the technical field of automobile data transmission, and the method comprises the steps that an application layer is connected with an automobile and reads vehicle information of the automobile, and a function instruction is obtained; the application layer sends function instructions to the system layer, wherein each function instruction corresponds to a first function protocol in the application layer; the system layer receives the function instruction and analyzes the function instruction to obtain any one of a tire pressure monitoring instruction, an automobile fault scanning instruction, an automobile diagnosis instruction, a data transmission instruction, an information acquisition instruction and an ECU ID reading instruction; and the system layer switches a second function protocol contained in the system layer according to a first function protocol corresponding to the function instruction, so that the system layer and the application layer transmit data under the same type of protocol. According to the invention, when data transmission is carried out on the automobile, transmission protocols can be switched randomly, so that detection of different functions can be carried out.

Description

technical field [0001] The present application relates to the technical field of automobile data transmission, and in particular, to a method and device for multi-protocol switching based on data transmission. Background technique [0002] The demand for automobiles has remained quite hot. With the economic growth and the improvement of international competitiveness, commercial vehicles have grown steadily and the market competition structure has tended to be reasonable; the combined effect of the sharp decline in the price of passenger vehicles and the increase in per capita income has led to rapid growth in demand. [0003] The formation of the national expressway network, the construction of new rural areas to improve rural road conditions, and the vigorous development of the logistics industry provide conditions for the development of the automobile industry. [0004] The more cars there are, the car diagnosis industry will follow. Cars are inseparable from daily mainte...
