Automatic fault detection system and method for electric bicycle

Abstract

The invention relates to an automatic fault detection system and a method for an electric bicycle. The automatic fault detection system for the electric bicycle consists of an electric bicycle controller connected with a rolling handle, a brake lever, an electric motor and a battery; a communication port of the electric bicycle controller is connected with a communication port of the fault detection terminal of the electric bicycle; the automatic detection method comprises: establishing a communication mode between the electric bicycle controller and the fault detection terminal of the electric bicycle, reading state data of equipment through the electric bicycle controller, and analyzing and displaying the state data of the equipment through the fault detection terminal of the electric bicycle, so as to achieve automatic detection of fault of the electric bicycle. The system and the method achieve automatic detection of the fault of the electric bicycle, can display fault points clearly, solve the problem of difficult fault detection of the electric bicycle, reduce maintenance time, has the characteristics of simple structure and convenient use, and are quite suitable for factories and dealers of the electric bicycles.

Description

technical field [0001] The invention belongs to the field of electric bicycles, in particular to an electric bicycle fault automatic detection system and method. Background technique [0002] In recent years, electric bicycles have developed rapidly due to their advantages of lightness, speed, environmental protection, energy saving, and low price. With the increase in the number of electric bicycles, the fault detection of electric bicycles has also become a very headache for electric bicycle manufacturers and electric bicycle dealers. Because the control circuit of the electric bicycle is very complex, the control circuit not only includes the electric bicycle controller itself, but also includes various external devices such as motors, brake handles, handles, batteries and other external devices connected to the electric bicycle controller, so the point of failure is relatively Many, it is very difficult to find electric bicycle faults. At present, the fault detection o...

Problems solved by technology

Because the control circuit of the electric bicycle is very complicated, the control circuit not only includes the electric bicycle controller itself, but also includes various external devices such as motors, brake handles, handlebars, batteries, etc. connected to the electric bicycle controller, so the point of failure is relatively small Many, it is very difficult to find electric bicycle faults

At present, the fault detection of electric bicycles usually adopts the detection method of traditional instruments, such as using a multimeter and other equipment to measure the voltage, current, resistance, etc. in the control circuit to gradually analyze and find the fault point in the control circuit. This fault detection method requires professional Personnel use manual methods for measurement and analysis to achieve, so there are problems of difficult and time-consuming fault detection
