The theft preventing method of a kind of electric vehicle parking field of the present invention wireless supervisory control system, monitoring and identification verification method of picking up the car are deposited in employing, namely delimit appointed area and unify parking place as electric motor car, parking stall blocking is carried out in this region, each unit is numbered, and the camera of correct position installation nearby monitors this region, as pilferage candid photograph equipment; Porch, each parking stall is provided with buried inductive coil, during for stealing generation, signal is sent to the main frame at identity registration recognition center, again by host driven wireless transmitter module, give candid photograph main frame by theft signal, by the figure and features feature of stealer under Taking Pictures recording.
Electric motor car deposit identity registration and identification proof procedure of picking up the car as follows:
(1) during car owner's bicycle parking, through identity registration recognition center, press stop button and carry out the registration of bicycle parking identity, now mini-printer prints a bar code, and be shown as the parking stall that car owner arranges on a display screen, and through ground buried coil when car is stopped the parking stall to specifying by car owner, now ground buried coil detecting sensor work, identity registration recognition central record inductive coil variable signal, now signal is odd-times;
(2) when car owner does not pick up the car and theft occurs, not by bar code scanning checking car owner identity, and directly car is taken away, inductive coil variable signal again detected, now signal is even-times, and this variable signal is sent to by wireless transmitter module and captures host machine part by single-chip microcomputer, the figure and features feature of stealer under this candid photograph master camera, be convenient to follow the trail of stealer, play anti-theft deterrence effect;
(3), when car owner normally picks up the car, by bar code scanning checking car owner identity, directly car can be taken away, not start candid photograph.
The theft preventing method step of electric vehicle parking field wireless supervisory control system is:
The first step: judged whether that key is pressed, when there being key to press, if bicycle parking key then forwards step 2 to, if key of picking up the car then goes to four, if under not having key to press to continue to have judged whether keyed jointing, button adopts interrupt mode.
Second step: judged whether empty parking space, if having, type slug shape code, display parking stall number, and have voice message.Otherwise to step one, and provide that voice message is current does not have empty parking space.
3rd step: car owner puts into parking stall car, the evidence that printer prints shape code is picked up the car as client, and start inductive coil and detect theft situation, and the data message of printing is passed to control single chip computer, facilitate single-chip microcomputer main frame to carry out unified management to parking stall.
4th step: when pressing key of picking up the car, then barcode scanner work, scanning bar code judges the car will getting which parking stall, and closes this parking stall inductive coil probe; If incorrect at bar code, authentication is unsuccessful, or when not carrying out authentication, is pushed away away by car by force, then alerting signal is sent to candid photograph main frame, records the figure and features feature of stealer.
5th step: when car owner loses type slug shape code time, then need car owner to collect evidence unblock to administrative office voluntarily.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention.All any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
