Outdoor projection device

Abstract

The invention discloses an outdoor projection device, and the device comprises a central processing unit, a Flash storage module, a GPRS wireless communication module, a GPS positioning module, a miniature projection module and a liquid crystal display module. The central processing unit and the GPRS wireless communication module are in bidirectional connection, and an input port of the central processing unit is connected with an output port of the GPS positioning module and an output port of the Flash storage module. The output port of the central processing unit is connected with an input port of the miniature projection module and an input port of the liquid crystal display module. The device provides outdoor navigation through a GPRS wireless network and GPS positioning, and displaysthe current location information through micro-projection. In the case of no base station signal, a big-capacity flash chip can be used for storing the map information, so the device is suitable for field exploration and training activities.

Description

technical field [0001] The invention belongs to an electronic device, in particular to an outdoor projection device, which is especially suitable for a miniature projection device for displaying maps for Google and Baidu. Background technique [0002] At present, with the improvement of people's living standards, the tourism industry at home and abroad is booming, and there are more and more donkey friends for wild adventures, and the equipment provided for wild adventures is also becoming more and more complete. However, wild adventures often visit places without base station signals. , so it is particularly important to provide complete map display and navigation services for donkey friends in places without base station signals. In the past, navigation services could be provided through maritime satellites, but the equipment was too expensive, so there is an urgent need for an electronic device to replace it in the market. Here On the basis of GPRS+GPS, field projection a...
