Description

The intelligent microcomputer theftproof lock

Technical field

The utility model belongs to the vehicle anti-theft technical field, and what relate generally to is a kind of intelligent microcomputer theftproof lock.Be applicable to motor vehicle, vehicles such as especially electric motor car, motorcycle (two take turns, three-wheel) use.

Technical background

Existing all kinds of electric motor car, motorcycle (two take turns, three-wheel) etc., the measure of being taked aspect antitheft also have and take vehicle power supply is controlled except that the theftproof lock of selecting various functions for use.Generally the mode of Cai Yonging is that a contact switch is set in the anti-theft lock rear end, and this contact switch and lock core rotate synchronously.During use, the rotating band movable lock core by key rotates, and contact switch rotates thereupon and contact with the vehicle power supply switch, thus in the unlatching theftproof lock conducting vehicle power supply, play the effect of duplicate protection.The drawback that this anti-theft measure exists is: lock body mostly is frame for movement greatly, complex structure not only, and fitting operation inconvenience, the manufacturing cost height, and destroyed easily; Control to vehicle power supply is to control by the contact/disconnection of contact switch, because one of them contact switch is arranged on the lock core and with lock core and rotates synchronously, as long as force rotational lock core, contact switch is contacted and conducting with the vehicle power supply switch; Perhaps the direct short-circuit power supply directly is connected the power line that connects the lock core contact switch with the vehicle power supply line, also can make power turn-on, and its theftproof performance has certain limitation.For this reason, " the micro computer puzzle theft-proof lock " that the inventor successively applies for and " vehicle power supply micro computer alarm " have better solved this type of problem, " but micro computer puzzle theft-proof lock " and " vehicle power supply micro computer alarm " all is in the control theftproof lock vehicle power supply switch to be carried out, so its structure design relative complex, cost cost height is installed and used inconvenience.And its opening ways is for utilizing logic chip control theftproof lock, because the employing logical course is realized control circuit, so certain limitation is arranged aspect interchangeability; And utilize remote controller control power supply, and because radio has certain requirement to environment for use, conductively-closed easily, so application facet has certain limitation.

Summary of the invention

The purpose of this utility model produces thus, proposes a kind of intelligent microcomputer theftproof lock.By taking the mode of Single-chip Controlling gross vehicle power supply and antitheft gear lock, further improved the theftproof performance of vehicle, have stable performance, open convenient, flexible characteristics.

The utility model realizes that the technical scheme that above-mentioned purpose is taked is: it mainly is made up of gear lock, lock body, single-chip microcomputer, power control unit and electric power starting device, single-chip microcomputer is arranged in the lock body, identification and control program in single-chip microcomputer, have been write, the electric power starting device is connected with the I/O mouth with microcontroller communication mouth RXD, TXD, the I/O mouth of single-chip microcomputer is realized the opening and closing of vehicle power supply and gear lock by the driving mechanism of power control unit control vehicle power supply switch and gear lock.

What electric power starting device described in the utility model adopted is known IC chip or Fingerprint Identification Unit or key passwords device.Or other similar products like.

The utility model is reasonable in design, simple in structure, owing to take the mode of Single-chip Controlling gross vehicle power switch and gear lock driving mechanism to carry out antitheft, not only theftproof performance is good, little, the stable performance of volume, and elliptical structure complicated mechanical latching segment, reduced cost of production, make more convenient to operate, quick.Warning delayed start-up program is arranged in single-chip microcomputer, behind the password bad, trigger warning delayed start-up program, warning device is opened, and sends warning, and sends simultaneously from lock signal, needs delay time later unlocking vehicle general supply and electric lock once more.The delayed start-up time can be set to 0-24 hour arbitrarily.The security performance height.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Embodiment 1

As Figure 1-1, intelligent microcomputer anti-theft switch described in the utility model mainly comprises gear lock, lock body, single-chip microcomputer, power control unit and electric power starting device composition, the reducing motor of single-chip microcomputer and gear lock is arranged in the lock body, identification and control program in single-chip microcomputer, have been write, what single-chip microcomputer adopted is the AT89C51 single-chip microcomputer, has write identification and control program, time-delay control supervisor in it.It is the patented technology that the inventor has applied for that gear lock, lock body and power control unit adopt, shown in Fig. 2-1,2-2, and the rotating of Single-chip Controlling DC speed-reducing 1, driving gear 2 drives driven gear 3, makes driven gear realize the opening and closing lock.The I/O mouth control motor control unit of single-chip microcomputer is realized motor positive and inverse, realizes vehicle is automatically locked by the motor-driven annular rack.What the electric power starting device adopted is the intelligent IC chip, and the IC read module of IC chip communicates by radio or electromagnetic induction and IC chip, and communication module is connected with TXD, RXD with the I/O of single-chip microcomputer.The IC chip is divided into contact IC and non-contact IC.Contact IC directly is connected IC-card and external interface device by tangible electrode contacts and carries out exchanges data in use; The non-contact IC chip is by the mode of radio wave or electromagnetic induction, with the data and the peripheral interface equipment communication of IC inside.Contact IC chip in use must be connected with electrode contacts, so the IC chip surface is easy to wear, water resistance is poor.The non-contact IC chip is embedded in card inside, and need not contact during use and can start power supply and gear control section power supply, so the preferred non-contact IC chip of this institute example.Non-contact intelligent IC chip encryption performance height, advantage such as transfer of data is stable.The IC-card key is card 6 structures, and IC-card chip 5 is embedded on this card 6 (as shown in Figure 3), IC-card chip 5 adopts be the data memory that is difficult for losing (ROM, EPROM), protection logic circuit, perhaps CPU.IC-card carries out communication by the mode and the communication module of radio wave or electromagnetic induction.
