Embodiment Construction

[0027] attached figure 1 Schematic diagram of communication links for POI detection regions. The point of interest detection area can be divided into multiple detection areas according to the user's choice, and each detection area is equipped with a geomagnetic detection node. A geomagnetic detection node usually includes a magnetic sensor, a conditioning circuit, an A / D converter, and a microcontroller. Because it is the beginning of the construction of communication information, the quality of the obtained information affects the accuracy of the whole system, so this system uses the PNI sensor RM3100 which is 10 times higher than the Hall sensor. The geomagnetic detection node realizes data interaction with the data receiving end through wireless communication technology.

[0028] The handheld intelligent terminal device is an auxiliary tool for vehicle information management. The geomagnetic detection node uploads the detected local detection data to the platform to prov...

Abstract

The present invention proposes a geomagnetic positioning and intelligent terminal construction method based on block chain traceable technology, which approximates the boundary area of ​​the navigation path based on position information; receives the user's selection of the boundary area, and takes the selected boundary area as the interest Point detection area; receiving the user's split selection of the point of interest detection area; dividing the point of interest detection area into a first point of interest detection area and a second point of interest detection area; when an object enters the point of interest detection area, obtain the point of interest The data of multiple smart terminals and geomagnetic detection nodes in the detection area is used to perform fingerprint matching calculation on the data of multiple smart terminals and geomagnetic detection nodes in the detection area of ​​the point of interest, so as to determine the position information parameters in the detection area of ​​the point of interest; The blockchain system traces the source, and expresses the data transmitted by each source node in a matrix, thereby representing the location information chain within a fixed time and area.

Description

technical field [0001] The invention relates to a method for positioning and building an intelligent terminal using block chain traceability technology and earth magnetic field detection. Background technique [0002] With the rapid development of society, urban traffic problems such as travel difficulties and traffic jams have gradually emerged, and the construction of intelligent transportation systems has attracted more and more attention and attention. Through the intelligent transportation system, drivers can plan travel routes in advance, avoid urban road congestion during this period, shorten travel time, and improve travel efficiency. The prediction of short-term traffic flow is of great significance to the development of intelligent transportation. By extracting the sequence characteristics of historical traffic flow, it can predict the traffic flow information in a short period of time in the future, so as to improve the reasonable allocation of traffic resources. ...
