Internet-of-vehicles data acquisition system based on embedded software secondary development

Abstract

The invention belongs to the technical field of Internet of Vehicles, and particularly relates to an Internet-of-vehicles data acquisition system based on embedded software secondary development, the system is divided into a vehicle-mounted terminal, a monitoring terminal and a cloud platform, and main functional modules of the vehicle-mounted terminal comprise an equipment control module, a programming module, a visualization module, an MCU control module, a communication module and a positioning module. The monitoring terminal processes related vehicle-mounted big data according to the cloud platform. Main functional modules comprise a data management module, a data analysis module and a data storage module. According to the invention, various data in the driving process of the vehicle can be collected and recorded in real time, and the driving state and the vehicle using state of the target vehicle can be monitored in real time and positioned and tracked in real time; and meanwhile, aiming at different user requirements, a system operation command can be designed by oneself, and the humanized design of the system based on different users is realized. Based on the cloud platform, analysis and management of vehicle-mounted big data are facilitated.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and in particular relates to a data acquisition system for the Internet of Vehicles based on secondary development of embedded software. Background technique [0002] At present, with the continuous development of the Internet of Things technology, in the field of smart car control, a large amount of local data of the car needs to interact with remote servers. The traditional vehicle terminal is developed based on an embedded system, which has a complex structure and high development costs. At the same time, it is compatible with the existing The equipment compatibility is poor and the scope of application is limited. [0003] Data transmission terminals often contain sensitive information of users, such as power-on passwords, user privacy, biometric information, etc. The traditional solution is to use software to encrypt, use an encryption algorithm and encryption key to generat...

AI Technical Summary

Problems solved by technology

Due to the openness and standardization of modern encryption technology, the encryption algorithm is not a secret, but the key is the real secret, and there are inevitably loopholes in the operating system, and attackers can break through the restrictions of the operating system to obtain the key, so pure software methods cannot guarantee key security

The terminal has powerful functions such as network connection, data upload, device control, and remote monitoring. The traditional method for authorized operators is to confirm the identity of the remote terminal through information such as IP address and MAC address, and these identities are easily forged, leading to attacks. the occurrence of the event

[0004] Through the above analysis, the problems and defects of the existing technology are: the security of the traditional data transmission terminal is insufficient, and it is extremely vulnerable to attack; the traditional vehicle terminal is developed based on an embedded system, and it is difficult to carry out secondary development

At the same time, the traditional vehicle-mounted terminal has complex structure, high development cost, poor compatibility of equipment, and limited application range
