Abstract
The utility model discloses an intelligent trouble surveymeter of an electric motor car, which comprises a motor detecting circuit, a controller detecting circuit, a handle detecting circuit, and a motor Hall detecting circuit. The intelligent trouble surveymeter has the advantages that the surveymeter is provided with the motor detecting circuit, the controller detecting circuit, the handle detecting circuit, and the motor Hall detecting circuit, so the fault detection of the electric motor car is convenient, quick and obvious, the professional knowledge requirement of the detection personnel is not high, the motor fault, the controller fault, the handle fault, and the Hull component fault occurred in the electric motor car can be quickly detected, and the measuring ability is more. When in detection, a power link or a signal wire of a detection part needing to be tested is connected with the corresponding detection contact only, the detection can be obviously and quickly performed through observing the display state of the corresponding LBD.
Description
Technical field
The utility model relates to the vehicle trouble detector, especially relates to the electric motor intelligent fault locator.
Background technology
Electric bicycle, electro-tricycle are subjected to people's the favor and the approval of city traffic control department deeply with its laborsaving, convenient, economic environmental protection, thereby are widely used in riding instead of walk and means of transport of people.But in use inevitably some faults can appear, as electrical fault, controller failure, handle fault, Hall element fault etc.The detection of above-mentioned fault adopts specific purpose tool to finish by the specialized maintenance personnel often, because the instrument that the fault different mining is used is also inequality, this brings inconvenience not only for the maintenance testing, and testing staff's professional knowledge is had relatively high expectations.
The utility model content
The utility model purpose is to provide a kind of maintenance to detect electric motor intelligent fault locator easily.
For achieving the above object, the utility model can be taked following technical proposals:
Electric motor intelligent fault locator described in the utility model, it comprises motor testing circuit, controller testing circuit, handle testing circuit, motor Hall testing circuit; Described motor testing circuit is joined end to end successively by three resistance R 14, R15, R16 and constitutes delta connection, draw detection contact a, b, c at the contact place of per two resistance respectively, on the resistance branch of every road, be in series with light emitting diode D11, D12, D13 respectively; Described controller testing circuit is made of integrated circuit (IC) 1, IC2, and 13 pin of described integrated circuit (IC) 1,4 pin, 3 pin, 2 pin are electrically connected with detection contact d, e, f, g respectively; 8 pin of described integrated circuit (IC) 2,4 pin are electrically connected with detection contact h respectively; The series arm ground connection that 14 pin of integrated circuit (IC) 1 and 3 pin of integrated circuit (IC) 2 are formed via resistance R 13, light emitting diode D10; Described handle testing circuit is made up of series arm and resistance R 11 branch roads that resistance R 12, light emitting diode D6 constitute, and a termination of resistance R 11 branch roads detects contact j, another termination direct supply; Series arm one termination that resistance R 12, light emitting diode D6 constitute detects contact k, and the other end is connected with ground with detection contact i, p respectively; Described motor Hall testing circuit is that the series arm that three routing resistances, light emitting diode constitute is formed, the upper end of three tunnel series arms all with direct supply, detect contact l and be connected, its lower end is connected with the input amplifier of being made up of triode BG1, BG2 with detecting contact m, n, o is connected and passes through resistance R 7 respectively; Described detection contact l, h are electrically connected by diode D14.
The utility model advantage just is the motor testing circuit, controller testing circuit, handle testing circuit, the motor Hall testing circuit that are provided with; Therefore easy, quick, directly perceived to the detection of electric motor car fault, less demanding to testing staff's professional knowledge, the electrical fault that can occur electric motor car, controller failure, handle fault, Hall element fault etc. are carried out fast detecting, and measuring ability is many.During detection, the power supply line or the signal wire that only need needs are detected the position are connected with the relevant detection contact, can be intuitively by observing corresponding diode displaying state, detect fast.
