Solution Overview
Problem
Existing systems for reporting environmental data from vehicles to cloud servers face challenges in ensuring data validity and reducing network and cloud server costs due to unreliable communication and the need for timely data transmission, particularly for time-dependent data like parking slot information.
Innovation Solution
A system installed in vehicles that includes sensors for geo-localization and environmental monitoring, an electronic control unit to buffer and transmit data in adjustable time intervals based on micro and macro environmental characteristics, and a communication unit for wireless communication, allowing for adaptive reporting that respects data validity and minimizes unnecessary data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is performed frequently to ensure data validity, then data freshness is improved, but network costs and server load increase
Solution Approach 1:
The system dynamically adjusts the reporting frequency based on vehicle speed and environmental context. When the vehicle is stationary or moving slowly in areas with many parking slots, reporting frequency increases to ensure data validity. When moving quickly through areas with fewer parking slots, reporting frequency decreases to reduce network costs. This dynamic adaptation resolves the contradiction between maintaining data validity and reducing network energy consumption.
Solution Approach 2:
The system changes the time parameter (reporting interval) based on vehicle speed and location. By modifying the reporting frequency parameter according to contextual conditions, the system optimizes the balance between data freshness and network resource consumption, addressing the contradiction between reliable data transmission and energy-efficient communication.
2Productivity
If reporting frequency is increased to capture timely environmental changes, then data freshness is improved, but network load and server processing increase
Solution Approach 1:
The system applies different reporting strategies to different spatial locations and time periods. In areas with high parking slot availability and low vehicle speed, the system increases reporting frequency to capture local environmental changes. In areas with fewer parking slots or high vehicle speed, reporting frequency is reduced. This localized adaptation optimizes data transmission timeliness while minimizing overall network load and server processing requirements.
3Reliability
If data transmission is performed continuously to ensure reliability, then communication reliability is improved, but unnecessary transmissions increase network costs
Solution Approach 1:
Instead of continuous transmission, the system employs periodic reporting with variable intervals. The reporting period is adjusted based on vehicle speed and environmental context, creating an optimized transmission schedule that maintains communication reliability while eliminating unnecessary transmissions. This periodic action with adaptive timing resolves the contradiction between ensuring reliable data delivery and reducing network costs.
Data Source
AI summary
A system for uploading data from a main vehicle to a cloud server is presented. The system includes a first sensor, a second sensor, a communication unit, and an electronic control unit. The first sensor obtains geo localization information of the main vehicle. The second sensor monitors first and second predetermined micro characteristics of the environment of the main vehicle. The communication unit transmits a report to an external cloud server and receives macro environment information indicating a predetermined macro characteristic of a geographic region in which the main vehicle is traveling. The electronic control unit repeatedly generates reports by collecting and buffering the first micro characteristic and transmits the reports in predetermined time intervals. The time intervals may be modified as a function of the second micro characteristic and the macro environment information.
