Described engine lock main frame 100 is also included as the power supply 8 of microprocessor 1, bluetooth module 2 and CCU power supply, and the voltage range of described power supply 8 is 9V to 16V; Or, also can in engine lock main frame 100, be provided with power connection points, be connected with Vehicular direct-current power supply, the voltage range of described Vehicular direct-current power supply is 9V to 16V.Use vehicle power, can reduce the cost of engine lock main frame, also make the design of its internal circuit more succinct.
Described startup controller 5 is for controlling the startup of vehicle motor motor, and it comprises at least one group of open contact, and the moving contact of described open contact connects the mouth of drive IC 4, and its static contact is connecting engine motor.
Use an engine lock for above-mentioned engine lock main frame 100, comprise engine lock main frame 100 and the mobile phone with Bluetooth function.In present embodiment, the iPhone mobile phone that described mobile phone 200 is current main-stream, described iPhone mobile phone is mated, is connected with the bluetooth module 2 of engine lock main frame 100 by the bluetooth unit (not shown) of iOS system.In other embodiments, described mobile phone 200 can also, for using mobile phone Android system, that have bluetooth applications, be mated, be connected with bluetooth module 2 by inner bluetooth applications.
In the present embodiment, the principle of work of engine lock is: car owner rotates to ACC shelves with key by OFF shelves, the variation of the detection ACC vehicle doorn state by ACC testing circuit, input to microprocessor 1 through its mouth, microprocessor 1 changes the behavior that judges car owner according to the level of input end, high level represents that ACC does not trigger, and low level represents that ACC triggers.If ACC triggers for a long time, represent that car owner, using in vehicle, removes engine lock.If microprocessor 1 judges ACC and meets at continuous trigger number of times the Bluetooth matching state that enters, represent that car owner will carry out Bluetooth matching, now, a control signal of input end output of microprocessor 1 is to bluetooth module 2, make bluetooth module 2 in can matching connection state, can mate with the iPhone mobile phone 200 with bluetooth applications function.Especially, the match is successful with bluetooth module 2 to only have iPhone mobile phone 200, and this iPhone mobile phone 200 just can become legal user, just can carry out bluetooth connection.While not carrying out the mating of iPhone mobile phone 200 and bluetooth module 2, the bluetooth mark of bluetooth module 2 is in show state not, in case mated connection by illegal car owner.
The iPhone mobile phone 200 having mated approaches after engine lock main frame 100, automatically carrying out bluetooth with engine lock main frame 100 is connected, after bluetooth connects, bluetooth module 2 sends and connects signal to microprocessor 1, after microprocessor 1 in engine lock main frame 100 detects that bluetooth connects, export a prompt tone signal to drive IC 4, through the mouth output of drive IC 4, drive buzzer phone 9 to send " ticking ", the two sound prompt tones that " tick ", this prompt tone represents that engine lock removes, now, when microprocessor 1 detects that ACC continues to trigger, be that ACC-DET holds while being low level, microprocessor 1 is exported an actuation signal, drive the open contact (50 that starts controller 5, 51) adhesive, the startup line that starts controller 5 is connected, in the time that rotating to START shelves by ACC shelves, key just can successfully start the motor of vehicle motor.ACC testing circuit 3 is detecting that ACC-DET end became low level after 20 seconds, and microprocessor 1 is exported a control signal, drives the contact (50,51) that starts controller 5 to disconnect adhesive.
At switch-off, and the iPhone mobile phone 200 that bluetooth has connected leaves after main frame, bluetooth connects disconnection, microprocessor 1 in engine lock main frame 100 detects that bluetooth module 2 is connected and disconnects with the bluetooth of iPhone mobile phone 200, at switch-off after 20 seconds, microprocessor 1 is exported a prompt tone signal to drive IC 4, output after drive IC 4 is amplified, drive buzzer phone 9 to send a sound prompt tone of " ticking ", this prompt tone represents that engine is locked, do not allow to start vehicle, now ACC testing circuit 3 detects when ACC triggers again, microprocessor 1 output alarm signal, output after drive IC 4 is amplified, drive alarm module to report to the police 6, one group of contact switch (60 of alarm module 6, 61) control external loudspeaker, the horn switch of bearing circle or LED circuit, sound and report to the police and/or LED lamp flicker warning, microprocessor 1 output alarm signal simultaneously, output after drive IC 4 is amplified, drives buzzer phone 9 to send alarm sound.
In present embodiment, bluetooth module 2, according to the control command of microprocessor 1, enters Bluetooth matching state.After Bluetooth matching, bluetooth module 2 records the MAC Address of matching unit, and be operated in coupled condition or the company's of returning state by the control command of microprocessor 1, the MAC Address of 4 iPhone mobile phones 200 that can the company of looping back have recorded, and the bluetooth coupled condition signal of exporting iPhone mobile phone 200 and bluetooth module 2 is to microprocessor 1, whether the electrical level judging that microprocessor 1 is exported by bluetooth module 2 bluetooth connects, high level represents not connect, and low level represents to connect.The blue teeth wireless data communication that after connecting, bluetooth module 2 is responsible between microprocessor 1 and iPhone mobile phone 200, implements the setting operation between the APP of iPhone mobile phone 200 and the microprocessor 1 of engine lock main frame 100.
Further, in order to strengthen the safety of engine lock, engine lock main frame 100 is provided with a CP trusted authentication chip 7 communicating to connect with bluetooth module 2.In the time that bluetooth module 2 connects iPhone mobile phone 200, iPhone mobile phone 200 is first and CP trusted authentication chip 7 communications by bluetooth module 2 meetings, carry out CP authentication.After iPhone mobile phone 200CP authentication success, could be connected with bluetooth module 2, otherwise this iPhone mobile phone 200 cannot be connected with bluetooth module 2.In other embodiments, while using mobile phone 200 Android system, that there is bluetooth applications function to be connected with bluetooth module 2 couplings, do not need to authenticate by CP trusted authentication chip.
Further, at bluetooth module 2, the password mating with outside bluetooth equipment is set, only has and input correct password with mobile phone 200, could the match is successful with bluetooth module.
The engine lock main frame 100 of present embodiment has seven terminal points, described seven point of connection comprise positive source 80, power cathode 81 terminal points, the warning output moving contact 60 of alarm module 6, break back contact 61 terminal points, the entrance point 30 of the ACC testing circuit of moving contact 50, break back contact 51 and a detection ACC vehicle doorn state of the startup controller 5 being connected with engine motor.For intelligent-induction built-in lock has nine terminal points, additional installation induction antenna, engine lock of the present utility model only needs corresponding 7 terminal points that connect, and its installation is more simplified, also more easily installed.
In present embodiment, the key door of vehicle has 4 gears, i.e. four vehicle doorn states.Wherein, one is " OFF ", and one is " ACC ", and one is " ON ", and also having one is exactly " START ".In other embodiments, the key door of vehicle can be other the many gears key doors containing " ACC " gear.
