Sensor Data Gateway for Cross-Controller Protocol Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intelligent vehicles, sensors may have data interfaces that are not compatible with multiple controllers, leading to incompatible data protocols and the need for redundant sensor configurations.
Innovation Solution
A first controller converts sensor data to a compatible protocol for a second controller using a first communication protocol supported by both, allowing data transmission between controllers without requiring redundant sensor setups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a data interface of a sensor is not compatible with multiple controllers, then each controller requires its own dedicated sensor interface, but this leads to redundant sensor configuration and increased hardware complexity
Solution Approach 1:
The patent introduces a gateway as an intermediary device between sensors and controllers. The gateway receives data from sensors using their native protocols and converts/forwards it to controllers using compatible protocols. This mediator resolves the incompatibility between sensor interfaces and controller interfaces without requiring redundant sensors or direct adapter hardware at each controller.
Solution Approach 2:
The gateway is designed with multi-functional capability to support multiple sensor protocols and multiple controller protocols simultaneously. It can adapt to different data interfaces and communication protocols, making a single gateway device universally applicable to various sensor-controller pairing scenarios, thereby eliminating the need for dedicated interfaces for each controller-sensor pair.
2Adaptability or versatility
If protocol conversion is implemented at the controller level, then data compatibility is achieved, but this increases controller complexity and processing overhead
Solution Approach 1:
The patent moves the protocol conversion function from the controller level to a dedicated gateway intermediary. The gateway handles all protocol translation, format conversion, and data adaptation tasks, while controllers maintain their native protocol handling capabilities. This separation reduces controller complexity and processing overhead while achieving full data compatibility.
3Reliability
If redundant sensor configurations are deployed for each controller, then each controller can independently access sensor data, but this increases system cost and hardware quantity
Solution Approach 1:
The patent merges multiple sensor connections and protocol handling functions into a single gateway device. Instead of each controller having direct connections to sensors, multiple controllers share access to sensors through the gateway, which consolidates the communication infrastructure and reduces the total number of physical connections and components required.
Solution Approach 2:
The gateway provides universal access to sensor data for multiple controllers simultaneously. A single sensor configuration can serve multiple controllers through the gateway's protocol conversion capabilities, eliminating the need for redundant sensor deployments while maintaining reliable data access for all controllers.

AI summary
This application provides a data transmission method, apparatus, and a system. The data transmission method includes: A first controller receives a data obtaining request from a second controller, where the data obtaining request requests to obtain data of a first sensor, the first controller supports a data interface corresponding to the first sensor, and the second controller does not support the data interface corresponding to the first sensor; the first controller receives first data from the first sensor; and the first controller sends converted first data to the second controller according to a first communication protocol. In this way, a second electronic apparatus can obtain data from the first sensor from a first electronic apparatus. This helps avoid redundant sensor configuration.
