Description
Technical field
The present invention relates to parking stall lock control technology, more particularly to refer to a kind of control device intelligently locked.
Background technology
With automobile become increasingly popular and city in the nervous of parking stall supply, with there are various parking stalls
Lock.Lock and manually locked to be mechanical most commonly.In use, the unlocking of ground lock and shut and be required to user and get off
Operated, and its it is inconvenient.In recent years, lock with some distant control vehicle positions occur.Lock distant control vehicle position be broadly divided into it is as follows
Three classes.The first kind is locked for the ground of the remote control scheme based on NORDIC companies nRF24 series radio frequency chips.First kind ground Lock Lee
With special physical remote control opening and closing signal, control berth lock lifting are sent to berth lock.The shortcomings that such ground lock is to can be only done
The simple functions of wireless serial, cipher round results are poor, and power consumption is larger, and need autonomous device, can not carry out Direct Communication with mobile phone.
Lock with locking to second class parking stall the parking stall for the remote control based on WiFi.Lock to such parking stall the built-in control electricity based on WiFi module
Road, it is allowed to which user on built-in WiFi mobile device by clicking on button the switch locked with controlling parking stall.For example, patent
CN204001911U discloses a kind of berth lock remoting solution.The advantages of locking to second class parking stall is network coverage area
Greatly, can apply to be configured with the mobile devices such as WiFi mobile phone, but such ground lock total system energy consumption is big, chip cost
It is high.Lock to 3rd class for the remote control scheme based on the mobile communication technology such as 2G, 3G or 4G, such as patent CN203961400U institutes
State.The advantages of locking to 3rd class is to be directly accessed wide area network, can realize that connection is remotely controlled anywhere or anytime, but its energy consumption pole
Height, communication chip and module cost are high, also need to continue payment network traffic fee to mobile operator during follow-up use
With, therefore practicality is not high.Moreover, parking stall of the prior art lock, the central processing unit built in it is even in need not
Working condition is also constantly in during manipulation ground lock, causes unnecessary power consumption.Operated to lock over the ground, the centre of ground lock
Reason unit needs the various states locked with detecting always, also causes unnecessary power consumption.Further, parking stall of the prior art
Locking with being locked in can not be alarmed during abnormal operation.
Therefore, prior art exist to it is a kind of can be with the need for the control device that low-power consumption mode is easily operatively locked
Will.
