Embodiment Construction

[0093] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0094] A MEMS sensor-based parking inertial navigation system, such as figure 1 shown, including:

[0095] The physical layer provides data support for the operation of the navigation system. The parking lot equipment provides the parking space distribution map and parking space status. The gyroscope at the mobile phone client is used to measure the change data of the mobile phone angle and the acceleration change data;

[0096] The transfer layer includes the information transmission layer. The information transmission layer includes the NB-IOT base station and the parking lot host. The NB-IOT base station is responsible for forwarding the data collected by the physical layer. The parking lot host forwards the instructions issued by the network layer. The transfer layer Guarantee the effectiveness, reliability and security of data transmiss...

Abstract

The invention discloses a parking space level parking inertial navigation system and navigation method based on an MEMS sensor. Inertial navigation combines an inflection point correction algorithm, vehicle dynamics and BP model training optimization inertial navigation model, is applied to an underground parking lot, improves the underground navigation accuracy, gets rid of external information dependence, and solves the terminal navigation problem of the underground parking lot; the information management problem of the parking lot is solved by applying NB-IOT, and intelligent and orderly management is realized by utilizing an information management system established by a computer technology, a sensor and other equipment, so that the safety and economy of the parking lot are improved, and the parking efficiency of the parking lot is greatly improved. Parking space change prediction and preference analysis are realized by fusing big data analysis on the basis of parking space level navigation, the user travel efficiency is improved, and the travel experience is improved. Regional resource allocation is optimized, urban travel and urban traffic are solved, urban appearance is improved, urban traffic informatization development is assisted, and huge economic effects can be generated.

Description

technical field [0001] The invention belongs to the technical field of vehicle navigation, relates to a MEMS sensor-based parking inertial navigation system, and also relates to a MEMS sensor-based parking inertial navigation method. Background technique [0002] As of the end of 2020, the number of cars in my country has reached 281 million, while the number of parking spaces in my country is only 119 million. According to the latest statistics from the Traffic Management Bureau of the Ministry of Public Security on April 6, 2021, the vacancy rate of parking spaces in Beijing, Shanghai, Guangzhou and Shenzhen parking lots has reached 44.6%, and the utilization rate of over 90% of parking spaces in cities across the country is less than 50%. Random parking, difficulty in finding parking spaces, and data isolation A series of problems such as "difficult to park" and "difficult to find a parking space" have aroused widespread concern in the society. [0003] Through on-the-sp...
