AI Technical Summary

Benefits of technology

This patented technology uses an improved car navigation device called Ground Microsensor (GMC) for detecting vehicles' movements during operation at different speeds or directions within a specific area. By capturing this movement with GMs it provides accurate location tracking capabilities even when there may have snow cover around them. Additionally, these systems work well under various environmental conditions such as temperature variations, rainwater levels, humidity changes, etc., making them ideal tools for managing traffic flow efficiently across multiple road networks. Overall, they provide efficient and reliable way to monitor cars while navigated through complex environments like airports.

Problems solved by technology

This patented technology solves issues with existing methods for detecting vehicles at different locations during traffic flow. These techniques have limitations due to poor visibility caused by rain water, snow coverings, fogging conditions, etc., which can affect their accuracy over longer periods of time. Additionally, these systems require expensive equipment that requires constant maintenance and updates from government agencies like FAA regulations.

Abstract

The invention provides a vehicle positioning and speed measuring system and method based on a grating array sensor. The system comprises a grating array module, a real-time data acquisition module, a vehicle position determination module and a vehicle speed determination module. The grating array module is used for acquiring a vibration signal of a vehicle in real time; the real-time data acquisition module is used for acquiring a vibration signal according to a preset acquisition time length and a preset sampling frequency to obtain a vibration sampling signal; the vehicle position determination module is used for determining the vehicle position based on the vibration sampling signal; the vehicle speed determination module is used for determining sampling point information corresponding to wheels of the vehicle based on the vibration sampling signals and determining the vehicle speed according to the sampling point information. According to the invention, all-weather monitoring of the vehicle is realized, and the efficiency and precision of positioning and speed measurement of the vehicle are improved.
