Description
Technical field
The invention belongs to burglary-resisting installation technical field, relate to a kind of intelligent space lock based on bluetooth.
Background technology
While motor vehicle offers convenience to the trip of people, the complication that parking difficulty has also become vehicles number to increase.When vehicle increases gradually, parking space is more and more nervous, the unrest of vehicle stops situation just unavoidable generations such as leaving about, fixing parking stall is preempted.To the unit or the individual that have fixing parking stall, how avoiding parking stall to be seized by other people, is headachy thing, and going out of berth lock just well solves this problem.
But the berth lock of current vehicle instigator is mostly mechanical type.When automobile turnover parking space, car owner will descend the landing bar of handlebar berth lock to prop up or put down and then lock, and uses and bothers very much.If encounter rainy day, use the car owner of mechanical berth lock just more inconvenient in the open.Now commercially also there are remote control parking stall lock and RFID radio-frequency intelligent berth lock to occur, but there is following problem:
(1) great majority are the effects can only playing remote controller lifting, such as present berth lock product does not all detect the function whether vehicle is parked in parking stall, if automobile is parked in parking stall and berth lock rises by car owner by mistake, make berth lock elevating lever be stuck at the bottom of car, vehicle can be caused to damage or berth lock damage.In addition, if when car owner drives to leave parking stall, forget and press remote keying, then berth lock can not work, and will make parking stall shared by other people.
(2) for RFID intelligent space lock, although can realize controlling berth lock automatic lifting, due to the Principle of Communication of RFID, the riding position of its vehicle-mounted RFID identification card must be arranged on car certain position outer, causes its installation very inconvenient.
(3) difficulty of intelligent space lock charging at present, charge in the place that car owner can only take 220V power supply; And for installing battery and carry out the berth lock of work, because powered battery makes berth lock, the working time is shorter, changing battery then becomes the thing that car owner frequently will do.
Automatic parking spot lock system for garage (application number: 201110334048.2, publication date: on April 4th, 2012).RFID chip is adopted to carry out finding range and information of vehicles differentiation; Wherein, the first, vehicle-mounted rfid card Intelligent Installation certain position outside car, its installation site is restricted; The second, comprise information of vehicles (such as license plate number) in vehicle-mounted rfid card, intelligence is write under professional person's operation by special rfid interrogator, is not easy to car owner and revises relevant information voluntarily.
The smart bluetooth networking control method that a kind of berth lock is multi-multipoint and device (application number: 201310491298.6, publication date: on April 9th, 2014) thereof.After it is mated with berth lock bluetooth module by Bluetooth remote control equipment (such as mobile phone), parking stall is that empty mode works to rely on elevation carrection sensor to judge whether; , there is the possibility of misoperation in this working method, as car owner forget situation such as band mobile phone etc. then berth lock then can not work.
Therefore, anxious the waiting of current berth lock needs the problem solved to be to reduce Overall Power Consumption, reduces landing electric current, reduces standby current, and the methods such as the dry cell power supply using self discharge less solve power issue; Further, make product more intelligent more humane, namely can see the eyes (sensor) of thing to product increase, make it more humane more intelligent; So design and aly possess Intelligent Recognition parking stall vehicle, and possess the intelligent space lock system of low-power consumption, while making individual parking stall not be preempted, can carry out easily stopping again has suitable realistic meaning and value.
