Abstract

The utility model discloses a three-phase brushless direct current motor controller with a card reading function for an electric vehicle. A radio frequency identification device (RFID) function module and a three-phase brushless direct current motor controller circuit unit are arranged in a same casing. The RFID function module is mainly formed by a carrier generation and power amplification circuit used for processing standard 125 kHz carrier signals generated by a single chip microcomputer, a detection and filtering amplification circuit and the single chip microcomputer used for decoding received signals. The three-phase brushless direct current motor controller has the advantages of intelligent two-way communication, low system cost, low frequency input, high sensitivity, low power consumption and compact equipment arrangement.

Description

Electric vehicle band card-reading function three-phase brushless dc motor controller

Technical field

The utility model belongs to the manufacturing of motor vehicle condition control unit, especially Electrical Bicycle vehicle condition control unit field.

Background technology

Electrical Bicycle has environmental protection, advantage conveniently; Electrical Bicycle is popularized day by day becomes the main walking-replacing tool of people in the city; Use the Electrical Bicycle of band remote keyless entering (Remote Keyless Entry RKE) function increasing at present; And vehicle-borne no key start-up control device needs to be provided with separately, and this configuration one side makes that the accommodation space of equipment is bigger, use RKE to need the user to unblank in addition at every turn and lock before all need click remote controller; Relatively trouble, and the possibility that exists quilt to cut sign indicating number, crack.

The utility model content

Above shortcoming in view of prior art; The purpose of the utility model is that a kind of battery-driven car of design does not have key start-up control device; Make it to adopt the mode of not having key operated PKE near formula; The vehicle-mounted control part is arranged in the same housing with the three-phase brushless dc motor controller, to reduce the installing space of equipment.

The purpose of the utility model is to realize through following design.

Electric vehicle band card-reading function three-phase brushless dc motor controller is characterized in that, RFID functional module and three-phase brushless dc motor controller circuitry unit are set in same housing; Said RFID functional module mainly is made up of the micro controller system that micro controller system is produced carrier wave generation that standard 125kHz carrier signal handles and power amplification circuit, detection and filter amplification circuit and decode to the received signal.

The utility model adopts the intercommunication of intelligence, and the equipment arrangement is compact low, and the low coverage recognized patterns is adopted in identification, greatly reduces by the possibility of cutting sign indicating number, cracking, and it is low to have system cost, low frequency input sensitivity height and advantage low in energy consumption.

Description of drawings

Fig. 1 is the structured flowchart of the utility model.

Fig. 2 is the circuit diagram of the utility model RFID functional module.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to detail.

Can see in conjunction with Fig. 1 and Fig. 2, RFID recognition function module and three-phase brushless dc motor controller circuitry DK are set in same housing (1); Said functional module RFID mainly is made up of the micro controller system that micro controller system is produced carrier wave generation that standard 125kHz carrier signal handles and power amplification circuit, detection and filter amplification circuit and decode to the received signal, and entire equipment is supplied power by power supply module DY.Three-phase brushless dc motor controller circuitry DK adopts the commercially available conventional electric machine controller of Chengdu Xuguang Science and Technology Co., Ltd; As the rising sun light KZQ-6B1 of section, KZQ-9B1, KZQ-12C, KZQ-15A all can, the control of functional module PKE is accepted in the keying of electric machine controller.

Fig. 2 has expressed the concrete structure of RFID recognition function module.Comprise that carrier wave produces and power amplification circuit (2), produce standard 125kHz carrier signal by micro controller system, the carrier signal after the amplification is launched through antenna L1.Detection and filter amplification circuit (3), detecting circuit restores the useful data signal with removing the 125kHz carrier signal, and the signal after filter amplification circuit adopts integrated transporting discharging LM358 to detection carries out filter shape and amplifies.Decode to the received signal by micro controller system (4) STC11F04E is little, thereby obtain the card number of ID card.STC11F04E accomplishes the decoding of Manchester code.Micro controller system STC11F04E accomplishes and communicates by letter with the electric machine controller singlechip chip through receiving next information, accomplishes identification, state recognition, and light, sound is reminded functions such as control.

After the identification success, Single-chip Controlling is accomplished electric machine controller standby operation automatically.That is, in service when getting into the electric machine control function status at motor, induction module monitoring motor status, two parts mutual communication is integrally formed.When the car owner leaves, need not the car owner and send instruction by on the key remote controller and lock door, but through identification car owner's identity automatically, decipherment distance is 1.8 meters.After the car owner gets off; Vehicle is identification car owner's identity constantly, and when the car owner left 1.8 meters on vehicle, vehicle can't recognize car owner's identity and will lock timely; Guaranteed the safety of vehicle and Che Nei treasure; Even near to have interference unit to disturb also of no avail because the interference of interference unit causes vehicle can't recognize car owner's identity more, vehicle locks door will be more timely.Thereby guaranteed user's property safety.Such design has realized that also the control convenience volume is compact more.

Claims

1. electric vehicle band card-reading function three-phase brushless dc motor controller is characterized in that, RFID functional module and three-phase brushless dc motor controller circuitry unit are set in same housing; Said RFID functional module mainly is made up of the micro controller system that micro controller system is produced carrier wave generation that standard 125kHz carrier signal handles and power amplification circuit, detection and filter amplification circuit and decode to the received signal.
