Problems solved by technology
The former generally requires different data acquisition and measurement equipment to support different types of transmission buses, which has a single function, high cost, and poor scalability; for the latter, commonly used signal conversion equipment usually only supports the conversion of one signal to PC serial signal , and collect data through a PC, the portability and ease of use are poor, and it is extremely inconvenient to debug in production or field experiments
In addition, these two calculation methods generally require large and expensive debugging equipment such as oscilloscopes and logic analyzers.

Embodiment Construction
[0023] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] In order to solve the problems of the prior art, the present invention provides a data calculation method based on an intelligent mobile terminal, which is implemented based on a vehicle bus debugging system, such as figure 1 As shown, the vehicle bus debugging system includes: a multi-mode signal converter 1, a signal synchronization adapter 2 and an intelligent mobile terminal data debugging module 3;
[0025] The multi-mode signal converter 1 has a multi-mode switching function, supports multiple bus types, can match and adapt to multiple types of bus signals and supports the USB peripheral protocol, and is used to convert bus data into a USB that matches the mobile terminal. Serial signals, convertible bus s...

The invention belongs to a vehicle electronic information system, and in particular relates to a data calculation method based on an intelligent mobile terminal. In the technical solution of the present invention, the data debugging module of the intelligent mobile terminal sets the bus type and bus parameters for the multi-mode signal converter, and the multi-mode signal converter switches to the corresponding bus type, and collects bus data according to the set bus parameters, and passes the signal The synchronization adapter sends it to the smart mobile terminal, and the data debugging module of the smart mobile terminal samples the data, analyzes the sampling results and displays them in real time. Compared with the prior art, the method has better adaptability and expansibility, is convenient to implement, and has low implementation cost.
Description
technical field [0001] The invention belongs to a vehicle electronic information system, and in particular relates to a data calculation method based on an intelligent mobile terminal. Background technique [0002] The network topology system based on the bus regards the initiator of each data exchange as a node, and each node uploads data to the bus according to the network protocol, and at the same time receives the data sent to it by the bus. There are generally two types of traditional bus data calculation methods: a. based on dedicated embedded data acquisition and measurement equipment; b. based on signal conversion equipment and PC data acquisition. The former generally requires different data acquisition and measurement equipment to support different types of transmission buses, which has a single function, high cost, and poor scalability; for the latter, commonly used signal conversion equipment usually only supports the conversion of one signal to PC serial signal ...
