Problems solved by technology
[0004] When a bicycle is running on a straight road, it can be regarded as only affected by rolling resistance and not affected by gradient resistance. Therefore, the coefficient of rolling resistance can be detected separately. friction, so the slope resistance coefficient cannot be detected separately, the present invention provides a method of using a bicycle to detect the road slope resistance coefficient and then obtain road slope information

The invention discloses a bicycle for collecting road information. The bicycle is used for carrying out segmented detection on road information according to detection intervals. The detection intervals are used for dividing a to-be-detected road segment into a plurality of segmented intervals. The bicycle comprises a collection controller which is mounted on the bicycle and is configured with a collection control program, a force sensor, a weighing sensor and an angle coder. The collection controller is fixedly mounted on a frame. The force sensor is mounted on a rear wheel rotation shaft andis used for detecting driving force applied to the rear wheel rotation shaft in real time. The angle coder is mounted on a front wheel or rear wheel rotation shaft. The invention also discloses a roadinformation collection method. Through adoption of the bicycle for collecting the road information provided by the invention, road surface comprehensive resistance information and slope of each segmented interval can be collected. The bicycle and the method can be used for collecting the road information and reducing road information collection cost and are convenient for popularization and application.
Description
technical field [0001] The invention relates to the technical field of bicycles and traffic information, in particular to a bicycle used for collecting road information and a method for collecting road information. Background technique [0002] When the bicycle is running on the road, the resistance it receives includes: road rolling resistance, road slope resistance, bicycle acceleration resistance, and bicycle air resistance. Among them, the road surface rolling resistance and slope resistance of the bicycle are directly related to the road surface and are proportional to the weight of the bicycle. The sum of the two road surface resistances can be called the comprehensive resistance of the road surface. [0003] The existing collection and recording technology of traffic road information rarely involves the collection and recording of road surface information. In order to characterize the obstruction effect of the road on bicycles, the inventor hereby proposes the index o...
