Abstract
The utility model discloses an anti-theft power supply switch for a microcomputer vehicle, which mainly comprises a single chip, a power supply control unit and a power supply opener. An identification and control procedure is written in the single chip; an I/O port of the single chip can control the power-on /power-off of a vehicle main power supply through the power supply control unit; and the power supply opener is connected with communication interfaces RXD and TXD and the I/O port of the single chip. The anti-theft power supply switch has reasonable design and simple structure. Because the anti-theft practice is carried out in a manner of controlling the vehicle main power supply by utilizing the single chip, the anti-theft power supply switch not only has good anti-theft performance, small volume and stable performance, but also omits a mechanical part with a complicated structure, thereby reducing the production cost and ensuring more convenient and quicker operation. Because an alarm delay opening procedure is set in the single chip, when a password is incorrect, an alarm device is opened through triggering the alarm delay opening procedure to issue an alarm and send out a self-locking signal simultaneously; and the vehicle main power supply and an electric lock only can be opened again after the delay. The delay open time can be arbitrarily set into 0-24 hours. Therefore, the anti-theft power supply switch has high safety.

Technical field
The utility model belongs to the vehicle anti-theft technical field, and what relate generally to is a kind of intelligent microcomputer Theft-proof power supply switch.Be applicable to self-propelled vehicle, especially vehicles such as battery-driven car, motor bike (two take turns, three-wheel) use.
Technical background
Existing all kinds of battery-driven car, motor bike (two take turns, three-wheel) etc., the measure of being taked aspect antitheft also have and take Vehicle Power is controlled except that the anti-theft column 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 switch, thus in the unlatching anti-theft column lock conducting Vehicle Power, play the effect of duplicate protection.The drawback that this anti-theft measure exists is: lock body mostly is physical construction greatly, complex structure not only, and fitting operation inconvenience, the manufacturing cost height, and destroyed easily; Control to Vehicle Power 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 switch; Perhaps direct short-circuit power supply with the power lead that connects the lock core contact switch directly and the Vehicle Power wire joint, 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 micro computer Car Burglar Alarm " have better solved this type of problem, but, " micro computer puzzle theft-proof lock " and " Vehicle Power micro computer Car Burglar Alarm " all is in the control anti-theft column lock Vehicle Power switch to be controlled, so its structure design relative complex, cost cost height is installed and used inconvenience.And its opening ways is for utilizing logic chip control anti-theft column 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 Theft-proof power supply switch.By taking the mode of Single-chip Controlling gross vehicle power supply, further improved the theftproof performance of vehicle, have characteristics such as stable performance, volume is little, fitting operation is convenient.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: it mainly is made up of micro controller system, power control unit, electric power starting device, identification and control program in micro controller system, have been write, the I/O mouth of micro controller system is by power control unit control vehicle source switch, the electric power starting device is connected with the I/O mouth with microcontroller communication mouth RXD, TXD, make Single-chip Controlling power control unit A by the electric power starting device, realize the opening and closing of Vehicle Power.
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, and is simple in structure, owing to take the mode of Single-chip Controlling gross vehicle power supply to carry out antitheft, not only theftproof performance is good, little, the stable performance of volume, and elliptical structure complicated mechanical latching segment, reduced productive costs, made more convenient to operate, quick.Warning delayed start-up program is arranged in micro controller system, 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 lorry once more.The delayed start-up time can be set to 0-24 hour arbitrarily.The safety performance height.
