Abstract
The utility model discloses an automobile seat memory device based on iris recognition, which comprises an iris image sensor, a position sensor, a DSP (Digital Signal Processor), a memory chip, a loudspeaker, an adjusting keyboard, an executing motor and a CAN expanding circuit, wherein the iris image sensor is used for collecting the iris information of a current driver; the position sensor is used for detecting the position information of the seat; the DSP is used for judging; the keyboard is used for adjusting the position of the seat; the executing motor is used for driving the seat to lift. According to the utility model, an iris recognition technology is adopted, so that the driver's identity information can correspond to the seat position information accurately, and the defects of keyboard mistakes, keyboard ageing, small memory capacity and insufficient intellectualization of memory in the conventional automobile seat memory system are overcome.
Description
Technical field
The utility model patent relates to a kind of automotive seat memory unit, refers to especially a kind of automotive seat memory unit based on iris recognition.
Background technology
The radical function of driver's seat is for chaufeur provides convenient operation, comfortable safety, tireless driver's seat again, is healthy closely bound up with chaufeur.According to the requirement of human engineering, chaufeur must have good static state and dynamic traveling comfort, thereby could improve the traveling comfort that chaufeur is taken, and reduces the fatigue of chaufeur long-duration driving.Seat is on automobile and inconspicuous parts, but is closely related with traffic safety with chaufeur is healthy.
Along with the develop rapidly of Eltec, automotive seat progressively progressively turn to motorized adjustment by manual regulation, and the high-grade automotive seat of part have increased memory storage function.Find by inquiry, it is aging that the memory unit of present stage exists button, key errors, and memory quantity is few, remembers the problems such as intelligent not.Given this: the utility model proposes a kind of automotive seat memory unit based on iris recognition.
Utility model content
This patent mainly solves the above problems: key errors, and button is aging, and memory quantity is few, remembers intelligentized not problem.
The utility model patent is to address the above problem adopted scheme to be: in automotive seat, introduce iris image sensor for gathering the iris information of current driver's, introduce position transduser for detection of the location information of seat, set up dsp processor, install additional and regulate keyboard for the position of adjusting seat, install actuating motor additional and be used for driving seat lifting, introduce storage chip for storage information simultaneously, install loud speaker additional, in the middle of chaufeur is adjusted seat position process and after completing, provide voice message.
Dsp processor has to be deleted the function of iris information and seat information and can be compared in the iris image storehouse in gathered iris image information and storage chip: if iris image stock is in this iris image information, dsp processor drives actuating motor to come into operation, in the feedback signal of the continuous receiving position sensor of dsp processor continuous and iris image storehouse, the corresponding seat information of this iris information of memory is compared, until actuating motor drives seat to arrive this seat information position; If do not exist, voice device can be pointed out in-position setting program, by regulating keyboard to drive actuating motor to carry out the adjusting of seat all directions and angle, after having adjusted, press definite key, current iris information is bound and is stored in storage chip together with seat information is corresponding.
In the utility model patent, provide a kind of reference method of deleting iris and seat information: after scanning iris, seat returns to home position, now pin and determine that key keeps a period of time, under voice message, longer pressing determines that key can be the iris of the storage of current driver's and seat information deletion.
The real-time modification of content needs due to memory storage, so can not use the storage space in dsp processor, and need to design separately a memory storage circuit, conventionally do not need the storage chip of disconnecting gear to realize, detailed iris information and corresponding seat position information are all stored in storage chip.
The storage chip of selecting in this patent should have can repeat erasable feature.
In addition, consider the feature of modern automobile Eltec: efficient, integrated control.This seat unit is not also an isolated system, and in the process of design, the dsp processor of selecting itself has carried the expansion of CAN bus, can be connected with car running computer easily, realizes the real-time Communication for Power of each node of network.
Technique effect of the present utility model: after adopting iris recognition technology, the described drawback of memory seat device all can be resolved originally.Iris has uniqueness, and along with the trend of development will be failure-free biological identification technology.Overcome storage key errors, the problem such as button is aging, memory is intelligent not.Select in addition erasable storage chip, guaranteed that device can overcome the few problem of memory quantity.
Accompanying drawing explanation
Fig. 1 is the device schematic diagram of the utility model patent.
In figure, 1. iris image sensor 2. position transdusers 3. regulate keyboard 4.DSP treater 5. actuating motor 6. loud speaker 7. storage chip 8.CAN bus expanded circuits.
The specific embodiment
Below in conjunction with 1 pair of the utility model patent specific implementation process of accompanying drawing, be described further.
First chaufeur enters automobile, inserts key, and device powers on automatically, enter wait state, wait state lower device carries out initialization, is about to the hardware system initialization such as all registers, port, storehouse, so that controller regulates, stores or the operation such as recovery.Then, after chaufeur scans eye alignment iris image sensor 1, whether dsp processor 4 detects the iris information gathering and is present in storage chip 7, if exist, dsp processor 4 drives actuating motor 5 to come into operation, the corresponding seat information of this iris information of the feedback signal of dsp processor 4 continuous receiving position sensors 2 continuous and storage chip 7 interior memories is compared, until actuating motor 5 drives seats to arrive this seat information position; If there is not this iris information, loud speaker 6 is pointed out in-position setting programs, by regulating keyboard 3 to drive actuating motor 5 to carry out the adjusting of seat all directions angle, and position transduser 2 can feed back to the location information of seat dsp processor 4 in time, each position or angular adjustment process have loud speaker 6 to send voice message, after seat adjustment completes, press definite key, current iris information and seat information store in storage chip 7 with regard to bound.
Because CAN bus has that real-time Communication for Power is strong, the few constant time range of the cost of later development and perfect international standard, be considered to one of the most promising fieldbus.In order to realize communicating by letter of seat unit and other automobile nodes, select tape CAN bus when choosing dsp processor.
For the deletion of iris, change the operation of part, can when writing the program of electronic control unit, set concrete operating mode.Present storage chip all has the feature that volume is little, memory capacity is large, wants, that is saved necessity of Delete superfluous iris information therefore storage chip can meet number needs, can not have any impact to operation.
Due to the uniqueness of iris recognition technology, can be by the starter gear of this technology binding engine, thus can reach the effect of automobile burglar, therefore, this device is not an isolated system.
The foregoing is only better embodiment of the present utility model, be not used for limiting practical range of the present utility model.Being that the equivalence that the content of every support the utility model patent application the scope of the claims is done changes and modifies, should be all technology category of the present utility model.
