To achieve these goals, the technical solution of the utility model is: a kind of automobile oil circuit control setup, it comprises fingerprint capturer, command input device, micro controller system and first electromagnetic valve that comes control oil channel to open and close by spool, the mouth of described fingerprint capturer is connected with the first input end of described micro controller system, described command input device is connected with second input end of described micro controller system, and first mouth of described micro controller system is connected with first electromagnetic valve.
First mouth of described micro controller system is connected with first electromagnetic valve by relay.
It also comprises second electromagnetic valve, the spool of second electromagnetic valve is vertical mutually with the spool of first electromagnetic valve, the spool side of first electromagnetic valve is provided with recess and this spool can move up and down in oil circuit, and the spool of second electromagnetic valve is positioned at outside the oil circuit, and the spool of second electromagnetic valve is stuck on the described recess when the spool of first electromagnetic valve is moved upward to the oil circuit complete opening.
Control the power supply of described relay disconnection by the contact in the spool of second electromagnetic valve to first electromagnetic valve.
It also comprises power-fail detection circuit and annunciator, and described power-fail detection circuit is connected with the 3rd input end of described micro controller system, and described annunciator is connected with second mouth of described micro controller system.
It also comprises telltale, and described telltale is connected with the 3rd mouth of described micro controller system.
Compared with prior art: the utility model has adopted advanced fingerprint recognition system, and the fingerprint that utilizes the car owner avoids resembling the key of other form as unique key; Utilize micro controller system as master control, memory unit, micro controller system has independent CPUs, internal memory and memory device, can store, judge finger print information, operation logic computer program and the instruction of sending Control of Automobile oil circuit, annunciator; Adopt the electromagnetic valve of improvement to come control oil channel, avoid anti-theft column lock to cause oil-break because of unexpected outage in the driving process.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a composition frame chart of the present utility model.
Fig. 2 is that oil circuit of the present utility model is opened scheme drawing.
Fig. 3 is that oil circuit of the present utility model is closed scheme drawing.
The specific embodiment
See also Fig. 1, the automobile oil circuit control setup of present embodiment comprises fingerprint capturer, instruction keyboard, power-fail detection circuit, annunciator, micro controller system, LCD display and the electromagnetic valve 1 that comes control oil channel to open and close by spool 1a, the mouth of fingerprint capturer is connected with the first input end of micro controller system, command input device is connected with second input end of micro controller system, first mouth of micro controller system is connected with electromagnetic valve 1 by relay, power-fail detection circuit is connected with the 3rd input end of micro controller system, annunciator is connected with second mouth of micro controller system, and telltale is connected with the 3rd mouth of micro controller system.
See also Fig. 2 and Fig. 3, automobile oil circuit control setup also comprises and micro controller system bonded assembly electromagnetic valve 2, the spool 2a of electromagnetic valve 2 is vertical mutually with the spool 1a of electromagnetic valve 1, the spool 1a side of electromagnetic valve 1 is provided with recess 4 and this spool 1a can move up and down in oil circuit 3, and the spool 2a of electromagnetic valve 2 is positioned at outside the oil circuit 3, and the spool 2a of electromagnetic valve 2 is stuck on the recess 4 when the spool 1a of electromagnetic valve 1 is moved upward to oil circuit 3 complete openings.Contact control relay among the spool 2a of electromagnetic valve 2 disconnects the power supply to electromagnetic valve 1.
Fingerprint capturer has adopted the capacitive transducer technology, and has adopted small-signal to create the semiconductor equipment of mountain range shape fingerprint image.The capacitive transducer of fingerprint capturer sends electronic signal, and electronic signal will be passed the surface and the dead property skin layer of finger, and reaches the live body layer (skin corium) of finger skin, directly reads fingerprint pattern, thereby has improved the safety of system greatly.In fingerprint recognition system, sensor has the ability to discern real skin temperature, resistance and electric capacity.The measure of these anti-deceptions is used for stoping artificial fingerprint, dead fingerprint and residual fingerprint.Fingerprint capturer is directly connected to the input interface of micro controller system, for micro controller system provides finger print information, so that micro controller system is preserved or the identification fingerprint, sends control command then.
Micro controller system (8051 series mini computer) is as master control, memory unit.Micro controller system has independent CPUs, internal memory and memory device.Can store, judge finger print information, operation logic computer program and the instruction of sending Control of Automobile oil circuit, annunciator.By the input interface of micro controller system, the finger print information that acquisition is provided by fingerprint recognition system, decision operation instruction then: increase the finger print information in new finger print information or the comparison memory device.If what receive that the car owner sends is to increase operation, then preserve finger print information to memory device; If the instruction of receiving the comparison fingerprint, all finger print informations in the readout memory that then circulates, contrast one by one.The fingerprint and the intrasystem fingerprint of input do not match, and the information of then returning " not matching " is to read-out.If coupling, the information of then returning " coupling " is to read-out, and the operation control command, and control relay is connected electromagnetic valve 1 power supply, after the magnet coil energising picks up spool 1a, automobile oil circuit 3 is switched on, and when spool 1a is picked up fully, spool 2a will be stuck on the recess 4 of spool 1a automatically, simultaneously split power supply by the relay of the control of the contact among spool 2a spool 1a is disconnected, and spool 1 is blocked by spool 2, the state that maintenance is often opened, safety and power saving more.This design can guarantee traffic safety, avoids anti-theft column lock to cause oil-break because of unexpected outage in the driving process.When oil circuit is closed in parking, pick up spool 2a, spool 1a just gets back to normally off automatically under the effect of spring.
The utlity model has perfect abnormal condition warning handles: when thief's cut-out, short circuit power circuit, and power-fail detection circuit notice micro controller system, micro controller system output control command is opened annunciator (ring sound); When running into the thief and rob car, the car owner can press danger button, leaves then, ensures life security, after micro controller system is instructed, start to timing program, computer program sends instruction after 1 minute, pick up spool 2a, spool 1a just gets back to normally off automatically under the effect of spring, and oil circuit 3 is closed; After closing Fuel path lock at unusual condition, can utilize car owner's finger print information to unblank again, if fingerprint capturer is destroyed, then need car is delivered to servicing center, utilize computer (with the password of car owner's setting) control single chip computer to open Fuel path lock.
