Detailed description of the invention
Fig. 1 is integral module schematic diagram of the present invention.Battery-driven car is after electric door lock is opened, motor identification module 2 in controller part 1 transmits key to the controller identification module 4 in motor part 3 by bus, controller identification module 4 in motor part 3 returns confirmation to the motor identification module 2 in controller part 1 receiving after accurate key, open the feed circuit 5 of Hall element simultaneously, allow motor part 3 normally to work.Controller part 1 proceeds to normal working after motor identification module 2 is received confirmation.As controller identification module 4 does not receive key or wrong cipher key, and motor identification module 2 do not receive the confirmation information, and controller part 1 and motor part 3 all will quit work.
Fig. 2 is controller part of the present invention, on the CPU of common controller part (STM8S903), defined motor identification communication interface pin9 (PB7) and connected motor identification communication interface circuit one end, the motor identification communication interface circuit other end connects the pin6 of CON4 socket.
Fig. 3 is the recognition control circuit schematic diagram of motor part of the present invention, and in Fig. 2, JZ1 socket is burning program interface; JZ2 socket is motor hall signal input interface, connects motor; JZ3 socket is motor hall signal output interface, connects controller; U4 is the CPU (STM8S903) of motor part, and the pin9 (PB7) in U4 is defined as controller identification communication port, connects controller identification communication port circuit; Pin32 (PD7) in U4 is defined as Hall power control signal delivery port, connects Hall power control signal output circuit.
The CON4 socket of controller part is connected with the JZ3 socket of recognition control circuit in motor part, and the communication port of two parts is linked togather.
Battery-driven car is after electric door lock is opened, the CPU of controller part transmits the CPU U4 of key to the control identification circuit of motor part, and communication signal transmission approach is: pin6 → CON4 socket of the resistance R 39 → CON4 socket in the motor identification communication interface circuit of pin9 (PB7) → controller part of the CPU of controller part connects the pin9 of the CPU U4 of the resistance R 4 → recognition control circuit of pin6 → controller identification communication port circuit of the JZ3 of the recognition control circuit of JZ3 socket → motor part.
The recognition control circuit CPU U4 of motor part is receiving the CPU of passback confirmation in accurate key Hou Jingyuan road to controller part, the high level of the pin32 of the U4 of motor part output simultaneously, aerotron Q2 (2N5551) in Hall power control signal output circuit opens, aerotron Q1 (A1013) conducting, give motor Hall power supply+5V-hall opens, motor is normally worked.
The CPU of controller part, receiving after the confirmation of recognition control circuit passback of motor part, proceeds to normal working.Like this, controller and motor are all in normal working, and battery-driven car is normally worked.
As the CPU U4 of the recognition control circuit of motor part does not receive key or wrong cipher key, motor Hall power control circuit will be closed, motor will quit work, as the CPU of controller part does not receive the confirmation of the recognition control circuit CPU U4 passback of motor part, controller part will quit work.
Whole identifying is only done once in the time powering on, as more changer controller or motor, or recognition failures, must re-power just and can identify for the second time.As long as like this controller with in motor, have the same being tampered, battery-driven car all will quit work.
Components and parts in foregoing circuit are commercial goods.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the spirit and concept in the present invention, within all should thinking and being included in protection scope of the present invention.
