Technical field

The utility model relates to the automobile burglar technology, relates in particular to the alarms and security systems for automobiles that a kind of control oil channel opens and closes.

Background technology

Along with rapid development of economy, China's owning rate of private car per capita just increases with multiple.But the stolen problem of automobile also becomes very severe simultaneously.

Cause the reason of stolen problem many, fail to play a role but one of them important reasons is an automobile burglar equipment.Mainly contain electronic anti-theft in the market, network monitoring is antitheft, smart card is antitheft.But electronic anti-theft is poor stability not only, and is given a shock also and can makes a noise, and produces sound and pollutes.And the shortcoming of network monitoring is exactly, if power supply is cut off or the signal conductively-closed after, just lost efficacy.The current more advanced antitheft meeting of smart card starts a leak, for example smart card is lost, just must arrive the auto repair technique center and do for supplement smart card, bring great inconvenience to the car owner, smart card contingency is leaked and is not brought out onboard, the thief just just can drive away automobile with the slightest effort, or others comes by means of car, and smart card just might be by people's decoding of taking away.

The utility model content

At the shortcoming of prior art, the purpose of this utility model provides a kind of alarms and security systems for automobiles, utilizes palmmprint line recognition technology to improve security with combining of single-chip microcomputer.

To achieve these goals, the technical solution of the utility model is: a kind of alarms and security systems for automobiles, it comprises palmmprint collector, command input device, single-chip microcomputer and the explosion-proof solenoid valve that comes control oil channel to open and close by spool, the output terminal of described palmmprint collector is connected with the first input end of described single-chip microcomputer, described command input device is connected with second input end of described single-chip microcomputer, and first output terminal of described single-chip microcomputer is connected with explosion-proof solenoid valve.Second output terminal of described single-chip microcomputer is connected with the automobile primary controller.

It also comprises power-fail detection circuit and alarm, and described power-fail detection circuit is connected with the 3rd input end of described single-chip microcomputer, and described alarm is connected with the 3rd output terminal of described single-chip microcomputer.

It also comprises display, and described display is connected with the 4th output terminal of described single-chip microcomputer.

It also comprises transmission lock, engine case cover lock, back-up case lock and glove box lock, and described transmission lock, engine case cover lock, back-up case lock and glove box lock are connected with the 5th output terminal of described single-chip microcomputer.

Compared with prior art: the utility model has adopted advanced Palm Print Recognition System, and the palmmprint that utilizes the car owner is as unique key; Utilize single-chip microcomputer as master control, memory unit, single-chip microcomputer has independent CPUs, internal memory and storer, the instruction that can store, judge palmmprint information, operation logic computer program and send Control of Automobile circuit, oil circuit, alarm, various case lock; Adopt explosion-proof solenoid valve to come control oil channel, avoid theftproof lock to cause oil-break and improve security 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 synoptic diagram.

Fig. 3 is that oil circuit of the present utility model is closed synoptic diagram.

Embodiment

See also Fig. 1, the alarms and security systems for automobiles of present embodiment comprises the palmmprint collector, instruction keyboard, power-fail detection circuit, alarm, single-chip microcomputer, LCD display and the solenoid valve 1 that comes control oil channel to open and close by spool 1a, the output terminal of fingerprint capturer is connected with the first input end of single-chip microcomputer, command input device is connected with second input end of single-chip microcomputer, first output terminal of single-chip microcomputer is connected with solenoid valve 1 by relay, power-fail detection circuit is connected with the 3rd input end of single-chip microcomputer, alarm is connected with second output terminal of single-chip microcomputer, and display is connected with the 3rd output terminal of single-chip microcomputer.

The palmmprint collector uses far infrared scanning, gathers the palmmprint pattern of corium, obtains the palmmprint characteristic by special algorithm, and compares to determine one's identity with database.The palmmprint characteristic comprises the palmmprint number, position and joining etc.The capacitive transducer of palmmprint collector 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 skin of palm of hand, directly reads the palmmprint pattern, thereby has improved the security of system greatly.In Palm Print 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 palmmprint, dead palmmprint and residual palmmprint.The palmmprint collector is directly connected to the input interface of single-chip microcomputer, for single-chip microcomputer provides finger print information, so that single-chip microcomputer is preserved or the identification palmmprint, sends steering order then.
