Display is able to achieve the function.
The video monitoring system includes parking lot monitoring module, and parking lot monitoring module is for obtaining parking lot picture number
According to, the data of parking lot monitoring module shooting are sent to central processing unit in real time, it is equipped with image zooming-out module in central processing unit,
For extracting empty parking space quantity and location information in parking lot, central processing unit deposits the output that image zooming-out module is extracted
Enter in shopping mall server, is obtained for consumer, the car statistics module is realized based on image feature extraction techniques, is
The prior art, therefore do not repeat them here.
The market service system that each mobile phone can be carried by the central processing unit of included WiFi function access, logs in
Can bind corresponding related information after account, related information refer to trailer-mounted radar number information, add good friend account information and
Store location information in market checks that trailer-mounted radar number information can be used for obtaining the location information that trailer-mounted radar finally occurs
(convenient for locking vehicle position), each account have independent coding, and the message that account is sent can be by corresponding coding one
And send, in order to trace signals source.
The automobile passes through trailer-mounted radar after a stop and location information is sent to communication terminal, then is transferred by communication terminal
To central controller, then the location information that the automobile is stopped is pushed to by central controller and binds the automobile mounted radar
Account removes the worry for looking for vehicle from order to which consumer can obtain the parking position of automobile in time, and the trailer-mounted radar is to be compatible with this
All models of system.
The principle of the present invention is: central processing unit is generated the module in the structure chart of market by three-dimensional modeling software three-dimensional
Three-dimensional model, then the data of that video monitoring system import in three-dimensional stereo model generated, while by existing
Image extraction method extracts the data and location information of empty parking space from the video module of parking lot, and by the empty parking space at extraction
Data and location information are loaded onto three-dimensional stereo model, and last central controller passes the three-dimensional stereo model of the production in real time
Enter in shopping mall server, is accessed for consumer.
Consumer's mobile phone open WiFi is connect with the WiFi module on communication terminal, and the data that WiFi module receives pass through
Signal adapter is converted into radiofrequency signal or/and digital signal, and radiofrequency signal passes through shortwave module B relayed transmitting to transmission
The shortwave modules A of module, digital signal is emitted by ZigBee module B is sent to transmission module through the receiving end ZigBee
ZigBee module A, after realizing that data interaction, central processing unit receive data, according to the request received from shopping mall server
In extract corresponding data after, the data transmission at extraction is turned round and stretched out the hand into machine along former road, to realize the transmission of data, the original road
Refer to the path that the data of acquisition are sent.
Application method of the invention is:
Consumer opens the interior nearest communication terminal in the WiFi and market of mobile phone and is connected by WiFi module, adds
Enter the communication system in market, account registration and information binding are then carried out by the communication system in market, information binding is
Refer to the information such as the store location in the number, the mobile phone IP address of good friend or market of addition trailer-mounted radar, when not knowing Road,
Consumer is according to destination name to communication terminal request data, and communication terminal will be locating for the destination locations and current account at this time
Store locations pass through ZigBee module B simultaneously or shortwave module B occurs to central processing unit, according to what is connected on central processing unit
Navigation module carries out path analysis according to starting point (position of consumer end) and terminal (destination), for obtaining mulitpath
Afterwards, navigation module path data generated is fed back to corresponding communication terminal and mobile phone by central processing unit, to realize navigation
Purpose；When anxious when consumer is to find the empty parking space in parking lot, empty parking space can be requested to communication terminal by mobile phone
Data, communication terminal, which repeats the above steps, sends a message to central processing unit, and central processing unit is according to bound in the account
The path is fed back to mobile phone, makes consumer by the position of car-mounted terminal position and empty parking space after calculating path by navigation module
Love vehicle is parked on empty parking space in time, eliminates and drives to saunter in parking lot, improve the service experience of consumer；Work as consumer
It makes an appointment and goes shopping with good friend, communication terminal nearest in WiFi and market on mobile phone is opened when good friend comes market and is connected,
After the communication system in market is added, the account of good friend is added, it can be with good friend's after then can uploading data by communication terminal
Position is shared, and shows from the three-dimensional structure figure on shopping mall server in mobile phone；If consumer's mobile phone electricity consumes
When to the greatest extent, the account that oneself can be logged in by touch display obtains vehicle or the position of good friend；If the mobile phone of consumer and good friend
When electricity all exhausts, can by after touch display login account on three-dimensional structure figure agreement meet address, to avoid
Two or more friends can not find the awkward situation of people in the same market；When consumer needs to drive to leave,
Can finally be issued by the trailer-mounted radar that mobile phone or touch display obtain vehicle signal position and nearest route.
The present invention, which is built market by short wave communication, can remove the cost for laying cable from a communication network, shorten
Transformation time in market, at the same can avoid in market dtr signal or to market structure it is not yet done caused by consumer get lost feelings
Condition is greatly improved consumption experience.
The above is only the preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, any
The transformation and replacement carried out based on technical solution provided by the present invention and inventive concept should all be covered in protection model of the invention
In enclosing.
