Multi-screen interaction system and method based on single host and single system

Abstract

The invention discloses a multi-screen interaction system and a method based on a single host and a single system. The system comprises an operation interface setting module, a multi-screen interaction manager, an interactive information control instruction module, a message management module, an input and state management module and a multi-screen interaction strategy configuration table, whereinthe multi-screen interaction manager is used for adapting to different screens and functions according to the corresponding relation of the strategy configuration table; the interactive information control instruction module is used for collecting input of a user on each screen, polling information input in each screen and inputting different requests to the host based on touch control and key operation; and the input and state management module is used for uniformly controlling and adjusting the state of each screen according to the function configuration in the multi-screen interaction strategy configuration table. According to the invention, multi-screen interaction is carried out in one system, the calculation overhead is low, the response speed is high, synchronous or asynchronous display control of each screen can be flexibly configured through the strategy configuration table, hardware only uses one host, and the hardware scheme is simple and low in complexity.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a multi-screen interactive system and method based on a single host and a single system. Background technique [0002] With the increasing development of science and technology, some existing cars are equipped with multi-screen devices, which are generally divided into the following two forms: low-end multi-screen interactive products are generally composed of the main driving instrument screen and entertainment center control screen; high-end car The instrument and the central control are made into a dual-screen form, and there is also a co-pilot screen or a rear headrest screen. Such as figure 1 As shown in , the traditional multi-screen system is equipped with a host (hardware unit) and a screen in each of the main driver, central control, co-driver, and rear headrests. The hosts are relatively independent, they control independent screens, and hardware resources cannot be...

AI Technical Summary

Problems solved by technology

The hosts are relatively independent, they control independent screens, and hardware resources cannot be shared. The display output, touch input, and application functions of the screen are realized by the software and hardware systems of their respective hosts, so the interaction between the screens is very low or basically non-existent. , and the overall solution cost is very high

At present, there is no solution for information interaction on one machine and multiple screens in this field
