Description
Technical Field
The invention belongs to the technical field of communication of the Internet of things, and particularly relates to a control method and device for remotely controlling an in-vehicle system.
Background
The internet of things is in the industrial germination stage, and the application fields are diversified, so that the industry has difficulty in achieving consensus on related communication standards and protocols. For example, semiconductor IC intellectual property authorizers, IC designers, terminal device brand owners, operating systems, and network service owners try to seize the internet-of-things service business in the beginning based on the existing economic scale advantages of the mobile device industry through a vertical integration strategy and active research and development and purchase. Some of the manufacturers further develop an operating system of the internet of things that can integrate or widely support communication standards and protocols, thereby creating a complete application service ecosystem. Therefore, with the mature technology, the function difference provided by each brand owner between the terminals or the sensing devices will be reduced and the mutual substitution will be greatly improved in the future, whereas the networking operating system platform serving as the basis for promoting services will become one of the true competitive cores of the internet of things.
In the internet of things, especially on a sensing layer, due to the existence of different sensor devices, the internet of things is cross-domain and cross-platform, and the used operating environment can be changed according to different industries or different fields. Therefore, cross-platform internet of things communication typically has the following problems:
the reusability is as follows: with the increase of the complexity of a cross-platform system, the internet of things embedded system with multiple Processors has various communication modes, and most of the current system designs independently realize communication aiming at respective application and hardware configuration, so that the communication modes are incompatible and the reusability is poor.
Reliability: communication between components, between processors, and between devices requires high communication reliability, but within the same Device, communication between different processors is not reliable and is susceptible to adverse environments such as electromagnetic interference, radiation, high and low temperatures, and the like. In addition, communication errors can occur in the communication between different devices.
Safety: communication between components under the same Processor may generally be without security measures. However, if the Processor is connected to the internet of things, even if the Processor communicates internally, there is a safety hazard. In addition, communication security problems also exist between different devices.
How to realize the in-vehicle service corresponding to the in-vehicle system remotely controlled by the intelligent terminal based on the intercommunication among the internet of things devices is a technical problem to be solved urgently at present, but at present, a technical scheme capable of solving the technical problem does not exist, and specifically, a control method and a device for remotely controlling the in-vehicle system are lacked.
