Problems solved by technology

[0002] Bicycle speed measurement products mainly have two methods according to different technologies and implementation methods: the first method is mechanical speed measurement, which mainly uses a mechanical counter, and the counter is triggered to add a number when the wheel turns a circle. This mechanical method is used on bicycles. There are many applications, but its measurement accuracy is low; the second method is electronic speed measurement, which mainly obtains electronic pulses through sensors to calculate the speed, but generally requires modification of the car body, which not only causes certain damage to the car body , and the cost is too high, and the simple use of electronic pulses to calculate the speed has certain limitations

Embodiment Construction

[0030] Such as Figure 1 to Figure 4 As shown, a track bicycle speed measurement device includes a signal detection circuit 2, a power supply circuit 3, a main controller 4, a voltage adjustment circuit 5, a wireless communication module 6 and a storage module 7; the signal detection circuit 2 includes a Hall sensor 602, magnet 601 and signal processing unit, described signal detection circuit 2 is arranged on the transmission plane of bicycle chain 603, and Hall sensor 602 is positioned between magnet 601 and bicycle chain 603, and is fixed by fixing mechanism 1 (can be by nut It can be fixed with the fixing ring, and it can also be fixed by the fixing clip. Since the similar fixing methods that can realize the above-mentioned fixing function are common and well-known fixing methods for those skilled in the art, they will not be described one by one here. .) because the junction of the bicycle chain 603 is an all-iron material, and there is no ferrous material at the non-join...

Abstract

The invention discloses a velocity measurement system of a track bicycle, consisting of a signal detection circuit, a power circuit, a main controller, a voltage regulation circuit, a wireless communication module and a memory module. The processing procedure comprises the steps that the signal detection circuit acquires signals generated by movement of a chain and performs the primary process on the signal; and the main controller can save the parameters such as the velocity and the like, and can control the wireless communication module to send the parameters to the user upper computer so as to finish the real time monitoring of the velocity of the track bicycle through the further analyzing of the processed signals. The velocity measurement system can send and save the data in real time without the need of transforming the bicycle body, save the use cost, and is suitable for masses of users.

Background technique [0002] Bicycle speed measurement products mainly have two methods according to different technologies and implementation methods: the first method is mechanical speed measurement, which mainly uses a mechanical counter, and the counter is triggered to add a number when the wheel turns a circle. This mechanical method is used on bicycles.
