Abstract
An electric vehicle controller with a code keyboard comprises a keyboard processing circuit and a controller circuit. The keyboard processing circuit comprises a single chip microcomputer, keys, an indication lamp and a communication interface. The keys, the indication lamp and the communication interface are respectively connected to pins of the single chip microcomputer, and the keys are used for inputting code data, and setting and confirming codes. The controller circuit comprises a micro controller circuit, a power driving circuit, a loudspeaker and a sensor, the power driving circuit, the loudspeaker and the sensor are all connected onto pins of a micro controller, and the micro controller circuit is used for receiving and processing indication and codes of a keyboard processing circuit and controlling the power driving circuit to control operation of a motor. The loudspeaker is used for generating sound alarm, and the sensor is used for sensing moving or damaging an electric vehicle without authority. The electric vehicle controller increases anti-theft performance of the electric vehicle.
Description
Technical field the utility model relates to the controller of a kind of automaton, particularly electric motor car.
Background technology is current, and electric motor car often occurs stolen.Though the electric vehicle anti-theft alarm device has been arranged, as long as the power lead of alarm is cut off, burglar alarm has not just been worked; Burglar alarm and controller do not have communication interface, and the disabled user only needs the electronic lock of electric motor car is coupled together with lead, and controller powers on and just entered normal mode of operation, but just cruising of electric motor car; Burglar alarm separates with controller, has increased the installation procedure of hardware circuit cost and producer.Therefore, current alarm also fails fundamentally to solve the burglar alarm problem.
The utility model content
The purpose of this utility model provides a kind of controller for electric vehicle with cryptoguard, and this controller is integrated in one electronic password lock, burglar alarm and controller, increases theftproof performance, reduces hardware cost.If do not input password, controller for electric vehicle can not be worked.
The controller for electric vehicle of the band cryptoguard that the utility model proposes comprises keyboard treatment circuit and controller circuitry two large divisions.Described keyboard treatment circuit comprises singlechip chip, button, pilot lamp and communication interface, and button, pilot lamp and communication interface are received respectively on the end pin of single-chip microcomputer, and button is used to input password numerical value, setting and affirmation password.
Controller circuitry comprises microcontroller circuit, communication interface circuit, power driving circuit, loudspeaker and sensor again.Communication interface circuit, power driving circuit, loudspeaker and sensor are all received on the microcontroller end pin, communication interface circuit is used to receive the instruction and the password of keyboard treatment circuit, wherein instruction comprises the setting code instruction and imports two kinds of cipher instructions, microcontroller judges it is unlock instruction or setting command according to instruction, if unlock instruction, with the comparison among the password that receives and the EEPROM that is stored in microcontroller, if password correctly then unblank; If setting command then is stored in new password among the EEROM of microcontroller.Power driving circuit is used for the drive motor running, and loudspeaker is used to the alarm of sounding, and whether sensor is used to respond to has the people to move or destroy electric motor car under unauthorized situation.
The controller for electric vehicle of the utility model band cryptoguard; be provided with communication interface; burglar alarm and controller are as a whole; before not importing proper password, controller for electric vehicle will be in self-locking state, and controller can't use; electric motor car also can't cruising; increase theftproof performance, reduced hardware cost, can effectively prevent the stolen of electric motor car.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a keyboard treatment circuit schematic diagram of the present utility model;
Fig. 3 is a controller circuitry schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, keyboard treatment circuit 1 comprises a single-chip microcomputer 3, pilot lamp 4, input keyboard 5 and communication interface 6.The keyboard treatment circuit has two effects, first setting code, its two be the input unlocking cipher.The user uses after keyboard 5 input passwords and the instruction (instruction comprises setting and unblanks two kinds), all imports single-chip microcomputer 3, handles the microcontroller 7 that the back coding sends to instruction by communication interface 6 controller for electric vehicle circuit 2 in single-chip microcomputer.Microcontroller judges it is unlock instruction or setting command according to instruction, if unlock instruction, with the comparison among password that receives and the EEPROM that is stored in microcontroller, if password correctly then unblank; If setting command then is stored in new password among the EEROM of microcontroller.
When the car owner leaves electric motor car, electric motor car is opened antitheft by the keyboard treatment circuit.At this moment, the sensor 10 of electric motor car is started working, if having the disabled user to move or destroy electric motor car, controller will send instruction control loudspeaker 9 and send chimes of doom.Before not importing proper password, controller for electric vehicle will be in self-locking state, and controller can't use, power driving circuit 8 no-outputs, and electric motor car also can't cruising.
If the car owner wants to start electric motor car, can proper password be input to controller by keyboard, remove the warning of electric motor car, allow controller be operated under the normal mode.But at this moment open the just cruising of electronic lock electric motor car on the car.
Introduce the connection and the effect of circuit diagram 2 below: button Q1-Q16 is used to input password and instruction among Fig. 2, and each button all is connected on the end pin of single-chip microcomputer U1, so which button single-chip microcomputer identification is.J2 among Fig. 2 is a communication interface, and communication interface is also received on the end pin of single-chip microcomputer, is used for instruction and password are sent in the microcontroller of controller for electric vehicle.
The connected mode of the key component of Fig. 3 and effect: the U6 among the figure is microcontroller chip PIC16F72, it is the core of entire circuit, be used to receive the password and the instruction of keyboard treatment circuit, and power controlling driving circuit (being denoted as U3 and Q1-Q6 among the figure) operate as normal, wherein U3 is the mosfet driver chip, Q1-Q6 is MOSFET, and the two has constituted power driving circuit jointly.LS1 among the figure is a loudspeaker, is used for reporting to the police, and loudspeaker links to each other with microcontroller end pin by a triode Q8, and triode Q8 is used for power amplification, to improve the volume of loudspeaker.The circuit that frame of broken lines 11 is indicated among Fig. 3 is the auxiliary functional circuit of controller, the current detection circuit that comprises the power circuit be made up of chip U5, is made up of chip U4A, the temperature sensing circuit of being made up of U4B and the counter electromotive force detection circuit of being made up of R15, R16, R18, R19, R21, R23, R30.
