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 user end is used to measure the change data of the mobile phone angle and 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 Guarantees the effectiveness, reliability and security of data transmissi...

Abstract

The invention discloses a parking space-level parking inertial navigation system and navigation method based on MEMS sensors. The inertial navigation combines the inflection point correction algorithm, vehicle dynamics and BP model training to optimize the inertial navigation model, which is applied to underground parking lots and improves the accuracy of underground navigation. , Get rid of external information dependence, solve the terminal navigation problem of the underground parking lot; use NB-IOT to solve the parking lot information management problem, use the information management system established by computer technology, sensors and other equipment, intelligent and orderly management, improve the safety of the parking lot And economy and greatly improve the parking efficiency of the parking lot. On the basis of parking space-level navigation, big data analysis is integrated to realize parking space change prediction and preference analysis, improve user travel efficiency, and improve travel experience. Optimizing the allocation of regional resources, solving urban travel, urban traffic, improving the appearance of the city, and helping the development of urban traffic informationization can produce huge economic effects.

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] By 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-spot ...
