Problems solved by technology
[0003] Purpose of the invention: In view of the above problems, the purpose of this invention is to provide a portable personal radar system for blind navigation, which can detect the shape, position and moving state of objects in the scanning range by using the radar system, which solves the problem of blind navigation. The problem is to reduce the damage caused by blind people because of obstacles around them. At the same time, the use of small millimeter-wave radar components reduces the cost of the radar system, solves the shortcomings of expensive personal radar systems, and solves the high cost of large-scale application of personal radar systems. The problem

The invention discloses a portable personal radar system used for navigation for the blind. The portable personal radar system comprises millimeter-wave radar assemblies, a high performance lithium battery, a signal processing apparatus, an earphone, and Bluetooth assemblies. The millimeter-wave radar assemblies are disposed on the head and the waist of a user respectively, can detect moving and static objects in front of a human body, and enables a detection result to form an electric signal, and then the electric signal is input to the signal processing apparatus. The signal processing apparatus processes the electric signal and obtains a concrete direction of a barrier in front of a human body, the concrete direction forms a voice signal, and the voice signal is then input to the earphone. The whole system is powered by the high performance lithium battery. The parts of the system, except the high performance lithium battery, are all provided with the Bluetooth assemblies. The advantages of the system are that a voice signal is output by means of the millimeter-wave radar assemblies and the signal processing apparatus, so a user is prevented from being hurt because the user fails to discriminate a barrier; and moreover, the main parts of the system are connected via the Bluetooth assemblies, so the system is more comfortable for a user to use.
Description
technical field [0001] The invention relates to a personal radar system, in particular to a portable personal radar system for blind people to navigate. Background technique [0002] The radar system can effectively detect the shape, position and moving state of objects within the scanning range. It has been widely used in ships, airplanes and other vehicles to navigate these vehicles. However, the current radar system equipment is expensive, complex in structure, and bulky. It is large and consumes a lot of power. It is generally used for large-scale equipment. Because the radar system can effectively detect the surrounding situation, the current technological progress, the volume of the radar system is continuously reduced, and the energy consumption is continuously reduced. The radar system is reduced and applied to the blind. Navigation becomes possible. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of this inv...
