Specific embodiment
The technical scheme that the present invention is provided is described in detail below with reference to specific embodiment, it should be understood that following specific
Implementation method is only illustrative of the invention and is not intended to limit the scope of the invention.
As shown in Figure 1 and Figure 2, a kind of interim unmanned plane traffic lights and intersection monitoring system include unmanned plane 1, on unmanned plane 1
It is provided with central control module, point duty lamp module 4, camera 2, loudspeaker 3, wireless communication module, memory and power supply
Device, central control module and above-mentioned each electronic component are connected to send control instruction and from these elements to them respectively
Receive data, electric supply installation be system in electronic component power.Central control module can use single-chip microcomputer, and 51 for such as commonly using are
Row.Communication module can be using WiFi communication module, Mobile Communication Chip, Bluetooth communication chip etc., it is also possible to be provided simultaneously with above-mentioned
Several communication chips, can be applied to different network environments.Memory can use TF read modules, coordinate TF cards to load
Different content.Point duty lamp module includes the DA chips, amplifying circuit and the traffic lights that are sequentially connected electrically, during DA chips are connected to
Centre control module.
Unmanned plane in this example has four rotor arms 5, and four rotor arms composition cross, loudspeaker is suspended on unmanned plane rotation
Immediately below Yi Bei centers, a camera is hung with each rotor arm, the rotor arm of camera distance four on each rotor arm
The distance at center is identical, keeps center of gravity in unmanned plane center of gravity.Electric supply installation uses battery pack, installed in the several of unmanned plane rotor arm
What center., TF read modules are onboard to be placed in the battery pack of rotor arm on pcb board.Traffic lights is also suspended on rotor
Under arm, the settable multiple of traffic lights.Need to keep balance in view of unmanned plane, therefore traffic should at least such as Fig. 1 shapes, dispersion suspension
Under two rotor arms relative to each other.Two traffic lights are hung with two rotor arms relative in Fig. 1.Traffic lights is preferably
Two-sided unrelated traffic lights, can carry out two-way commander on a road direction.As needed, can be hung under each rotor arm
Traffic lights, can command the traffic of four direction, during suspension with respect to the traffic lights on two cantilevers apart from rotor arm center distance
Should be equal so that center maintains the geometric center of gravity of four rotors, to keep unmanned plane to balance as far as possible.
Central control module on unmanned plane can read the content in memory, retransmit to traffic lights module,
Point duty lamp module is lighted, extinguishes and flashed according to the instruction that central control module sends.Camera can shoot multiple side
To live outdoor scene and send to central control module, central control module is stored in can sending data to memory,
Real scene image can also be transmitted to user by wireless communication module.
Based on wireless communication module, interim unmanned plane traffic lights and intersection monitoring system in the present invention can be moved with user
Dynamic terminal device(Such as mobile phone, IPAD)Connection.Control software can be installed on mobile terminal device, software is manipulated by,
User can manipulate unmanned plane and fly to fixed position, and the traffic lights that the central controller on operation unmanned plane is read in TF cards refers to
Wave data.The data is activation carries out digital-to-analogue conversion to the DA chips of point duty lamp module, then is amplified by amplifying circuit, finally
Transmit to traffic lights, control lighting, extinguish and flashing for traffic lights.When needing to be propagandaed directed to communicate, user is to mobile terminal
The microphone of equipment carries out voice recording, and speech data is delivered to central controller of the invention, center control by WiFi communication
Device processed is sent to the DA chips of loudspeaker module and be sent to after digital-to-analogue conversion after amplifying circuit is amplified and will finally be put into
Signal be sent to loudspeaker.Camera shoot scene can real-time Transmission to customer mobile terminal, for user's monitor in real time.
Traffic police obtains the real time status of all directions vehicle flowrate that camera under unmanned plane shoots, can be by central controller, flexibly
Control the time of traffic lights.Central control module in unmanned plane can also be according to the shooting picture of airborne camera, by mould
Formula recognizes that dynamic judges the vehicle flowrate situation of all directions, according to the rule of internal configuration, adds algorithm(Such as:Vehicle flowrate is divided into
5 grades, if 5 grades, the direction time of passing through is 60 seconds;4 grades, the direction time of passing through is 50 seconds, 3 grades of correspondences 40 seconds, 2 grades of correspondences 30
Second, 1 grade of correspondence 20 seconds;)Determine that traffic lights should allow the time for passing through in all directions, and according to all directions being calculated
On the traffic lights time carry out the work of Comprehensive Control each traffic lights.Market traffic flow detector is usually to detect a certain place
The vehicle of process, from a direction in the present invention will need by vehicle it is different, therefore using the common car of in the market
Flow detector is not used in carrying out flow anticipation in the present invention.The present invention provide vehicle flowrate determination methods be:Unmanned plane stops
In the middle of crossing, level altitude(Trapezoidal segmentation is conveniently carried out, and is contrasted with template), taken pictures, for capture image, such as
Shown in Fig. 3, according to the road conditions at this crossing(Keep straight on, turn left and turn right bend quantity)Trapezoidal segmentation is carried out, according to date and time
Day and night is drawn, the trapezoidal interior vehicle condition in each track in picture is analyzed, trapezium base is closest to the side at crossing
To, how many judgements are vacated according to trapezoidal top, analyze the vehicle queue distance for waiting to pass through and substantially quantity of per pass.Specific side
Method be first with several standard form comparative analyses, reuse intensity contrast pattern-recognition, the image of every 3 or 5 seconds of collection, car
The different situation of stream(1 grade:Without car, two grades:There are car, three-level:Compare many cars, level Four:Many cars, Pyatyi:Car is blocked up), according to
Template compares, and identical area is different, vehicle flowrate is judged according to how much of the same area, percentage how much, here
Do not need accurate vehicle flowrate numeral, as long as rank substantially, as long as be divided into 5 grades (by 5 grades of areas set in advance or
Percentage range value judges) just, the picture scope and time that can be recognized with the simplified mode.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned implementation method, also includes
Constituted technical scheme is combined by above technical characteristic.It should be pointed out that for those skilled in the art
