Bluetooth-technology-based accurate tire air pressure monitoring system for electric bicycle

Abstract

The invention discloses a Bluetooth-technology-based accurate tire air pressure monitoring system for an electric bicycle. The system mainly comprises an ARM (advanced reduced instruction-set computer machine) processor, a sound and light prompting module, a display, a signal conversion circuit, a Bluetooth 4.0 module II and an air pressure data acquirer, wherein the air pressure data acquirer comprises an air pressure sensor and a Bluetooth 4.0 module I, and is fixedly arranged in a vacuum tire of the electric bicycle; the ARM processor, the signal conversion circuit and the Bluetooth 4.0 module II are fixedly arranged in a headstock of the electric bicycle; the sound and light prompting module and the display are fixedly arranged on a display panel of the electric bicycle; the sound and light prompting module, the display and the signal conversion circuit are connected with the ARM processor respectively; the Bluetooth 4.0 module II is connected with the signal conversion circuit; the air pressure sensor is connected with the Bluetooth 4.0 module I; information data is wirelessly transmitted between the Bluetooth 4.0 modules I and II. The system is simple in structure, reasonable in design, safe, reliable and low in using cost.

Description

technical field [0001] The invention belongs to auxiliary equipment for electric bicycles, and in particular relates to a precise monitoring system for tire air pressure of electric bicycles based on bluetooth technology. Background technique [0002] An electric bicycle refers to a mechatronic personal vehicle that uses a battery as an auxiliary energy source on the basis of an ordinary bicycle, and is equipped with operating components such as a motor, a controller, a battery, a steering handle, and a display instrument system; the 2013 "China According to data from the Electric Bicycle Industry Innovation Summit Forum, the number of electric bicycles in China exceeded 200 million by 2013. It can be seen that electric bicycles have become one of the common means of transportation for people to go out. Because electric bicycle is much heavier than general bicycle, so the tire that it uses is bigger, and the air pressure in the tire is also higher, usually needs special-pur...

AI Technical Summary

Problems solved by technology

However, users of electric bicycles seldom take the initiative to inflate, and it is difficult to know whether they need to inflate. They often realize it after the tire slips due to low air pressure during driving; at this time, If there is no car repair shop nearby, you can only push the car forward, which is time-consuming and laborious; and there are certain safety hazards

In addition, in summer, when electric bicycles are exposed to the sun, the tire pressure may increase due to high temperature, which may cause tire explosion in severe cases
