A Smart City Positioning and Navigation System

Abstract

The invention discloses an intelligent city positioning navigation system comprising a vehicle inductor set, a position measuring and calculating unit, a distributed auxiliary unit, a positioning navigation processing unit, a radar distance measuring speed measuring unit, a small barrier identification unit, a first LTE wireless transmit-receive unit, a vehicle displaying unit, and a cloud navigation service center. The intelligent city positioning navigation system is capable of solving a problem of GPS system positioning blind area, and realizing accurate measuring on positioning navigation; accurate early warning on vehicles is realized via a plurality of barrier detection; and navigation convenience and real-time performance are improved via auxiliary of the cloud navigation service center.

Description

technical field [0001] The invention relates to the field of navigation, in particular to an intelligent city positioning and navigation system. Background technique [0002] A smart city is a system. Also known as network city, digital city, information city. It not only includes basic elements such as human brain wisdom, computer network, and physical equipment, but also forms a new economic structure, growth mode, and social form. A smart city integrates the sensor-based Internet of Things and the existing Internet, and through fast calculation and analysis processing, implements the implementation of personnel, equipment and infrastructure in the network, especially public industries such as transportation, energy, commerce, security, and medical care. A type of urban development that is managed and controlled in real time. [0003] As an important part of a smart city, smart transportation is getting more and more attention. Taking navigation as an example, the core...

Problems solved by technology

[0004] However, in the prior art, no matter whether the GPS unit or the Beidou positioning and navigation unit is used, the GPS signal fading is very large or the GPS signal cannot be received, the function of positioning and navigation will not be realized; when the number of receiving GPS is small, It will also lead to inaccurate positioning data, and there are problems such as random deviations, that is, in the prior art, there is a problem of positioning blind spots in both positioning and navigation systems that use GPS units or Beidou positioning and navigation units.

[0005] With the wide application of gyroscopes, in order to solve the problem of positioning blind spots in existing positioning and navigation systems, various vehicle positioning monitoring and navigation systems based on gyroscope inertial navigation, or GPS / Beidou and gyroscope integrated navigation have emerged one after another. However, In the prior art, the system implementation cost of the above solution is relatively high, and the error is also relatively large, resulting in inaccurate navigation and positioning

[0006] In addition, in order to reduce safety accidents, the existing vehicle navigation system generally installs a distance measuring unit to give an alarm when the distance between the vehicle and the obstacle is less than the safe distance. , the distance measuring device using the above technology still has monitoring blind spots, especially for small-sized obstacles, which is difficult to identify, so that there will be system omissions or false alarms, and the stability is poor
