Embodiment 1

[0029] combined with figure 1 A passive electronic guiding device based on an energy harvester is shown, which can be used in urban parks, living areas, campuses, and outdoor hiking trails. In this embodiment, the passive electronic guiding device based on an energy harvester is set In the campus, it includes an electronic luminescent signboard 2, a pedal 1, and several buttons 31. Below the pedal, there is a power generating device for converting the kinetic energy generated when stepping on the pedal into electrical energy. Below the key is a power generating device for converting the kinetic energy generated when the key is touched into electric energy. connect.

[0030] The electronic luminescent signboard 2 includes a map indicator board 21 and several illuminants 22 located below the map indicator board 21. The current location, several destinations corresponding to the keys, and the current location are marked on the map indicator board 21. The walking route between t...

Embodiment 2

[0040] combine Figure 4 As shown, the electret thin film energy harvester of this embodiment has been improved on the basis of the first embodiment, specifically in the gap between the electret thin film 43 and the upper electrode 41, and the electret thin film 43 A spring 46 is provided in the gap between the lower electrode 42 , and the spring 46 is used instead of the elastic film 44 in this embodiment, and the function of the spring 46 is the same as that of the elastic film 44 in the first embodiment.

Embodiment 3

[0042] combine Figure 6 As shown, a passive electronic guiding device based on an energy harvester can be used in occasions such as city parks, living areas, campuses, and outdoor hiking trails. In this embodiment, the passive electronic guiding device based on an energy harvester is set In the campus, it includes an electronic luminescent signboard 2, a pedal 1, and several buttons 31. Below the pedal 1, there is a power generation device for converting the kinetic energy generated when stepping on the pedal into electrical energy. The bottom of the button 31 is provided with a power generating device for converting the kinetic energy generated when the button is touched into electric energy. The power generating device adopts more than one electret thin film energy harvester, the electret thin film energy harvester and the electronic luminous indication brand electrical connections.

[0043] The electronic luminescent sign 2 adopts a liquid crystal display, and the liquid ...

Abstract

The invention relates to a passive electronic signpost based on an energy collector. The electronic signpost comprises a plurality of electronic luminous signposts, a pedal and a plurality of keys. Apower generation device used for converting kinetic energy generated when the pedal is treaded into electric energy is arranged below the pedal. A power generation device used for converting kinetic energy generated when the keys are touched into electric energy is arranged below the keys, the power generation device adopts more than one electret film energy collector, and the electret film energycollectors are electrically connected with the electronic light-emitting indication boards one by one. According to the passive electronic signpost based on the energy collector, a power supply doesnot need to be installed for power supply, line connection is relatively simple, installation and maintenance cost is low, the environment is not affected, and interestingness is improved.

Description

technical field [0001] The invention belongs to the technical field of electronic maps, and in particular relates to a passive electronic guiding device based on an energy harvester, which is suitable for occasions such as city parks, living quarters, campuses, and outdoor hiking trails. Background technique [0002] At present, most of the guide signs that have been widely used in urban parks, living areas, campuses, shopping malls and outdoor hiking trails are ordinary map guide signs. Due to the large area of ​​the park and many buildings or road forks, ordinary map-type signage is complicated, especially when several location information (such as current location and destination) need to be displayed at the same time, it is not convenient for tourists to find their way. Although AutoNavi Map or Baidu Map has a good positioning function, it cannot play its role in areas with weak or no signal for mobile phones. In multi-storey buildings such as shopping malls, AutoNavi Ma...
