Problems solved by technology

[0002] Modern society advocates low-carbon and energy-saving culture. Bicycles are a low-carbon and environmentally friendly means of transportation, which are favored by the majority of users. However, when using bicycles to ride into wild tree-lined trails, valleys and tunnels, GPS satellite signals are affected. Obstacles obscuring traditional satellite navigation
In addition, many current navigators are not suitable for bicycle navigation. For example, the current stopwatch cannot provide the attitude information during bicycle driving.

Embodiment Construction

[0076] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0077] Reference herein to "one embodiment" or "an embodiment" refers to a particular feature, structure or characteristic that can be included in at least one implementation of the present invention. "In one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0078] see figure 1 . figure 1 It is a system block diagram of the MEMS-based bicycle navigation system of the present invention. Such as figure 1 As shown, the bicycle navigation system includes: a stroke measurement module, a vehicle speed detection module, a collision detection module, a rollover detection module, an attitude detection module and a navigation module.

[0079] The travel measurement module is mainly composed of an AMR geomagnetic ...

Abstract

The invention provides a bicycle navigation system based on MEMS (Micro-electromechanical Systems). The bicycle navigation system comprises a route measurement module, a vehicle speed detection module, a collision detection module, a rollover detection module, a posture detection module and / or a navigation module. By virtue of the bicycle navigation system, a navigation problem of a bicycle can be solved, a current position of a user is displayed in real time and dynamic posture information of the bicycle is output in real time; the speed and route of the bicycle can be detected, the user is reminded of preventing the bicycle of rollover, and the collision detection module can provide accident evaluation and rescue-calling services.

Description

technical field [0001] The invention relates to the field of navigation and positioning, in particular to a MEMS-based bicycle navigation system. Background technique [0002] Modern society advocates a low-carbon and energy-saving culture. Bicycles are low-carbon and environmentally friendly means of transportation, which are favored by the majority of users. However, when using bicycles to enter wild tree-lined trails, valleys and tunnels, GPS satellite signals are affected. Obstacles obscure the use of traditional satellite navigation. In addition, many current navigators are not suitable for bicycle navigation. For example, current stopwatches cannot provide attitude information during bicycle driving. [0003] Therefore, it is necessary to propose a new scheme. Contents of the invention [0004] The purpose of the present invention is to overcome the defect of prior art, provide a kind of bicycle navigation system based on MEMS, it can solve the navigation problem o...
