Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing 1-2.
Embodiment one
Referring to Fig. 1, Fig. 2; normally starting car: the driver inserts key and twists; the S terminal that ignition switch 6 is connected on the protector 2; do not generate electricity signal output of generator 4 before this; voltage in the simultaneity factor electric voltage observation circuit 8 is lower than 13V (26V); protector 2 is connected starting relay (11) at once; make direct current motor 3 self magnetic switch 5 electric work; drive engine running; through 2-5 rear engine second normal car; the driver judge motor car, twist back key, ignition switch 6 disconnects finishes startup.
Embodiment two
Improper starting: referring to Fig. 1, Fig. 2
1, motor is being difficult for car; the driver starts continuously, and igniting process starts identically with normal, but is being difficult for car because of motor; the driver is twisting key does not put; surpass 15-20 second when starting time, the prescribe a time limit delay time of control circuit 7 of the igniting in the protector 2 arrives, and power switch 10 is turn-offed; 50 terminals of protector 2 disconnect and being connected that B+ holds; startup is forced to interrupt, and at this moment the driver must twist back key, just can enter next time and start.
2; motor normal car; but ignition switch electric contact adhesion: the ignition trigger process is with normally to start car identical; motor normally moves; but because of ignition switch 6 electric contact adhesions or the vehicle-mounted relay electric contact of front end sticking; perhaps firing switch lock Returnning spring elastic force is not enough and can not reset and cause the S terminals in the protector 2 to get electric can not normally the disconnection; this moment generator 4 because of motor car begin the generating; N/W or D+ terminal on its generating signal spontaneous motor 4 reach protector 2, cut off the electricity supply after the 5-10 delay time second operation of termination starting electrical machinery of the generator signal delay circuit 9 in the protector 2.
3, engine start difficulty: the ignition trigger process is with normally to start car identical; but, multiple reason is being in like non-unstable state because of causing motor; this moment, generator 4 also can and then produce generating signal off and on; the N/W end or the D+ terminal of the spontaneous motor 4 of its generating signal reach protector 2; generator signal delay circuit 9 in the protector 2 is because of there being the 5-10 delay function of second; can not make at once to start and interrupt; in most cases motor can step into stable operation in second at 3-5; subsequently, twist back ignition key by the driver again and cut off ignition switch.
4; motor is logical in normal operating igniting misconnection: because of vehicle jolts and vehicle-mounted relay setting angle mistake causes being in operation; the S terminal of protector 2 is unexpected to be got; but because generator 4 is in normal power generation; its signal has been delivered to the N/W end of protector 2; therefore the drive circuit of the power switch 10 in the protector 2 is in blocking; although fire signal is arranged comes; protector 2 can conducting yet. simultaneously because be carved with system voltage observation circuit 8 detection system voltages during the B+ of protector 2 end; system voltage is above 13 (26V) under the normal condition, and the drive circuit of protector 2 inside is therefore locking also.Be that the following 2 kinds of protections of this kind state are worked simultaneously, even guarantee that firing tip S is electricly unexpected, starting circuit can not connected yet.
