Vehicle Data Collection System with Periodic Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles parked for extended periods consume battery power unnecessarily due to frequent connections with remote servers for data transmission, which can reduce battery life and increase energy consumption.
Innovation Solution
A vehicle data collection system that minimizes energy consumption by sending data only during specific times, such as when the vehicle is parked or when requested by a remote server, using a control module to manage power supply to sensors and communication modules, and classifying vehicles based on their position to optimize data requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data transmission is performed frequently to maintain accurate database updates, then data accuracy is improved, but battery consumption increases
Solution Approach 1:
The system implements periodic data transmission by establishing a time interval between successive data sending operations. The control module sends vehicle data to the remote server at predetermined periodic intervals rather than continuously, which maintains database accuracy while significantly reducing battery consumption during parked vehicle periods.
Solution Approach 2:
The system performs preliminary classification of vehicles into different groups based on their characteristics and parking locations before data transmission. This preliminary action allows the remote server to selectively request data only from specific vehicle groups, avoiding unnecessary transmissions and reducing overall battery consumption while maintaining data accuracy for relevant vehicles.
2Measurement precision
If sensors and communication modules remain active continuously, then data collection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the operational state of sensors and communication modules based on vehicle status. During parked periods, these components are activated only when necessary for data transmission and then deactivated, rather than remaining continuously active. This dynamic control maintains measurement precision when needed while significantly reducing energy consumption during idle parked periods.
3Loss of information
If vehicles transmit data at frequent intervals, then database update accuracy is improved, but battery life decreases
Solution Approach 1:
The system establishes a periodic transmission schedule where vehicle data is sent to the remote server at predetermined time intervals during parked periods. This periodic approach ensures the database remains accurately updated with vehicle information while significantly extending battery life compared to continuous or frequent transmission schemes.
Solution Approach 2:
The remote server performs preliminary classification of parked vehicles into different groups based on vehicle characteristics and parking location data. This classification allows the server to selectively request data from specific vehicle groups, reducing the total number of transmission requests and thereby extending battery life while maintaining database accuracy for classified vehicles.

AI summary
The invention relates to a vehicle data collection method and system comprising: detecting the start of parking (401) of a vehicle by means of an activation/deactivation indicator; detecting the position (402) of the vehicle by means of a positioning module (103) connected to a control module (101), based on the parking start detected; detecting at least one parameter of the vehicle by means of at least one sensor (106) of the vehicle connected to the control module (101) via a data collection module (104), based on the parking start detected; sending an activation signal to a remote server (108), by means of a communication module (105) connected to the control module (101), said activation signal being indicative of the vehicle parking start; a vehicle identifier; the position of the vehicle; and at least one parameter of the vehicle; and registering (403) the vehicle, by means of the remote server (108), in a parked vehicle database.
