Pedestrian navigation device

Abstract

In order to provide users with a guiding path suitable for shading, sheltering from rain, etc. for pedestrians, the present invention relates to a navigation device for pedestrians, which includes: a CPU unit, a map database, a GPS unit, a touch screen, a CMMB unit, a sun Azimuth calculation unit and voice speaker; the map database stores: road section information suitable for pedestrians to walk, building information around each road section, tree information suitable for shading or rain shelter around each road section; CPU unit obtains weather according to CMMB unit Information; if the current season is summer and the weather is sunny and the user chooses to use the sunshade path calculation mode, the CPU unit obtains the sun orientation information of the current position according to the sun orientation calculation unit, and then calculates a walking guide path suitable for shade; If the current weather is rainy and the user chooses to adopt the sunshade and rain avoidance route calculation mode, the CPU unit calculates a walking guide route suitable for rain avoidance.

Description

technical field [0001] The invention relates to a navigation device for pedestrians. Background technique [0002] The processing of the existing navigator for pedestrian navigation is as follows: from the starting point to the destination, only the recommended route is given, and the recommendation is unilaterally based on factors such as the length of time, the distance, whether the traffic is smooth or the cost required , the result of such navigation cannot satisfy users with more choices. [0003] For example: Chinese patent document CN201069361 discloses a navigation device that can provide traffic information, which includes: a CPU unit, a GPS receiver, a map database, a program database, a touch screen control unit, and a TMC receiving module for wirelessly receiving traffic information . The CPU unit of the navigation device receives traffic information through the TMC receiving module and displays it through the touch screen control unit, providing users with rea...

Problems solved by technology

[0004] The disadvantage of the above-mentioned navigation device in the prior art is that when it is applied to pedestrians, it cannot provide a guiding path suitable for pedestrians such as shading and rain shelter.

[0006] But the existing navigation device still can't draw the guiding path suitable for shady walking after adopting the automatic calculation method of the above-mentioned solar orientation.
