Embodiment 1

[0015] See figure 1 , The navigation device of the present embodiment comprises: CPU unit 1, and map database 4, GPS unit 6, touch screen 3, CMMB unit 2, sun azimuth calculation unit 8 and voice speaker 7 that are connected to CPU unit 1 in turn. Among them, the touch screen 3 is connected to the CPU unit 1 through a display control circuit and a map generating unit, and also has ROM, RAM, and auxiliary storage devices connected to the CPU unit 1 . CMMB is the abbreviation of China Mobile Multimedia Broadcasting in English.

[0016] The map database 4 stores: road section information suitable for pedestrians to walk, building information around each road section, and tree information suitable for shading or rain shelter around each road section.

[0017] CPU unit 1 obtains weather information from CMMB unit 2 .

[0018] If the current season is summer and the weather is sunny and the user chooses to adopt the sunshade path calculation mode, the CPU unit 1 obtains the sun ori...

Embodiment 2

[0037] On the basis of Embodiment 1, the map database 4 also stores: information on whether each road section is a bustling commercial road section, and information on whether each road section is a quiet landscape road section.

[0038] If the current season is summer and the weather is sunny and the user chooses to adopt the sunshade path calculation mode, while considering the bustling commercial road section or the quiet landscape road section, the CPU unit 1 obtains the sun orientation information of the current position according to the solar orientation calculation unit 8, and then calculates the solar orientation information according to the user's calculation method. The input destination, and the path information in the map database 4, the building information and tree information around the path, and whether the road section is the information of the bustling commercial road section or the quiet landscape road section are calculated to be suitable for shading and have...

Abstract

The invention relates to a navigation apparatus for foot passengers, which provides a guide path for foot passenger, adaptive to shading and rain shielding. The apparatus comprises: a CPU unit, a map database, GPS unit, a touch screen, a CMMB unit, a sun orientation calculating unit and a voice horn. The map database comprises: section information adaptive to foot passenger walking, building information surrounding each section, tree information surrounding each section for shading and shielding rain. The CPU unit acquires the weather information based on the CMMB unit. During summer and sunny day, when the user adopts the sunshade path calculating mode, the CPU unit acquires the sun orientation information in the current position based on the sun orientation calculating unit and calculates the guide path adaptive to shady walking. During rainy day, when the user selects the sunshade and rain shielding path calculating mode, the CPU unit calculates the guide path adaptive to rain shielding walking.

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...
