Summary of the invention

The purpose of this invention is to provide a kind of multifunctional intellectual bicycle lock, solve existing single function and the form of bicycle lock, strengthen the safety of bicycle, realize the intellectuality of bicycle lock.

The technical scheme that technical solution problem of the present invention is taked is: a kind of multifunctional intellectual bicycle lock comprises that smart lock is controlled system, lock body, unit and humiture collection unit test the speed; The cellular installation that tests the speed is fixed on the steel wire of tyre rim and on the bracing frame of bicycle front fork.

Described smart lock is controlled the pulse signal that system sends by the unit that tests the speed, and obtains the speed of a motor vehicle and accumulative total mileage number through algorithm, and the data that gather of humiture collection unit are processed through smart lock control system simultaneously, is presented in smart lock control system.

Described lock body comprises chain, tapered end, locking plate, binary coded keyboard, binary coded demonstration lamp panel and spring; Be provided with pressure sensor after spring.

Utilize above-mentioned a kind of multifunctional intellectual bicycle lock to carry out the method for lock and unlock: after tapered end enters the lockhole of smart lock control system when locking, the tapered end extrusion spring, spring stress also is sent to pressure sensor with power, pressure sensor is controlled system because stressed output corresponding signal feeds back to smart lock, and smart lock control system starts locks.

adopt binary system to carry out release when release, be comprised of 5 binary coded and 1 bit check codes, binary coded is random the generation, and the password of release each time is difference all, when smart lock control system receives outside unlock command, smart lock control system is by 5 binary coded and 1 bit check codes of one group of random sequence of 6 I/O mouth output of single-chip microcomputer MSP430, check code is randomized to either in binary coded keyboard key arbitrarily, all the other 5 keys are the locking key of binary system solution, the binary coded order of exporting by each I/O on binary coded demonstration lamp panel is carried out the LED lamp and is lighted prompting, check code prompts for Chang Liang on binary coded demonstration lamp panel, the user presses corresponding key according to the order of prompting at binary coded keyboard, after input is completed, press again the verification code key, complete release, password prompt disappears simultaneously, if continuous three input password mistakes, smart lock is controlled system will start alarm.

In described unlock method unlock command by the outside independently the release device carry out, the user presses the switch SW 1 in release circuit, causes light emitting diode SED utilizing emitted light, feeds back to single-chip microcomputer MSP430 by receiving circuit, smart lock control system starts release.

The invention has the beneficial effects as follows: the invention solves standard bicycle lock single function and form, adopts and binary codedly carry out release with check code, and password is change at random, strengthened the safety of locking.Simultaneously, strengthened informationization technology, shown in real time the speed of a motor vehicle, mileage number, current time and humiture, can satisfy the cyclist and understand current vehicle condition and environment.
