Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is further elaborated.
The present invention is with small-sized many rotor wing unmanned aerial vehicles for carrier, carry imaging device express highway section is performed road monitoring intelligent, quick, flexible, efficient and patrols and examines operation, improve road safety level, and by remote wireless transmission or 3G/4G transmission network, real-time vehicle violation data is transmitted to freeway management department and road information distribution platform. Being prone to judge owing to Expressway Road situation is simple and takies the situations violating the regulations such as urgent track, therefore this system easily realizes and flexible and efficient.
As it is shown in figure 1, a kind of highway based on unmanned plane monitoring system A violating the regulations, issue subsystem A4 including flight subsystem A1, monitoring subsystem A2, message transmission subsystem A3 violating the regulations and road information. Wherein flight subsystem A1 includes unmanned plane main body A 11 and flight control modules A12, monitoring subsystem A2 violating the regulations includes picture recognition module A21, camera module A22 and GPS locating module A23 violating the regulations, message transmission subsystem A3 includes wireless transport module A31, and road information is issued subsystem A4 and included freeway management department A41 and road information distribution platform A42. Wherein unmanned plane main body A 11 can adopt small-sized multi-rotor aerocraft. Relative to artificial and fixing camera recognition method, small-sized multi-rotor aerocraft has the advantages such as flexible and efficient, simple to operate, cost is low. By loading various kinds of sensors, image acquisition transmission equipment, control process chip and radio transmission apparatus on multi-rotor aerocraft, the real-time monitoring to road traffic condition both can be realized. Unmanned plane main body A 11 is made up of frame, brushless electric machine, electron speed regulator, propeller, flight controller, wireless receiver and high-capacity lithium battery. Flight control modules A12 includes main control chip, GPS module, barometer, gyroscope, accelerometer and radio receiving transmitting module. Wirelessly flight control modules A12 can be carried out the planning of flight path and checking of state of flight on ground. The image of camera collection is mainly analyzed by picture recognition module A21, it may be judged whether there is the situation of vehicle peccancy (mainly taking emergency relief track), and vehicles peccancy carries out the extraction of car plate locking identification and license plate number. If there is vehicle peccancy situation, needing to send a signal to flight control modules A12 and carrying out the adjustment of height so that car plate locking identifies and the extraction of license plate number. And judge whether vehicle takies Emergency Vehicle Lane and mainly extract the straight line of Emergency Vehicle Lane, judge whether there is vehicle on the right of straight line, again this vehicle being compared with emergency vehicles (ambulance, police car etc.) and hazard warning flasher situation if there is vehicle, if Emergency Vehicle Lane is not emergency vehicles, judging and not opening hazard warning flasher to it is determined that act of violating regulations. If Emergency Vehicle Lane is not emergency vehicles, judge and open hazard warning flasher to it is determined that urgent behavior. Camera module A22 and GPS locating module A23 violating the regulations is respectively used to the pictorial information of registration of vehicle act of violating regulations (urgent behavior) and the geographical position information in (needing emergency relief) section violating the regulations. Wireless transport module A31 can carry out point-to-point remote transmission by the remote transmission module of 2.4GHZ or use 3G/4G module construction information network to carry out the remote transmission of violation information, this mode is only small by the impact of distance, can make unmanned plane that highway system-wide section is covered, identify situation violating the regulations and send violation information. Freeway management department A41 and road information distribution platform A42 refers to the data base of current fastlink administration section and the road information platform of the information bulletin board of highway and highway respectively.Violation information is sent storage and to data base and on road information distribution platform, issues the management of the relevant administration section easily facilitating highway and the process of situation violating the regulations, substantially increase the efficiency of management of highway and the level of security of highway.
As in figure 2 it is shown, a kind of highway based on unmanned plane monitoring system violating the regulations includes below scheme: the first cruise route of setting high-speed highway and the flying height normaled cruise in flight subsystem A1, carry out normal flight cruise operation. Next the imaging device collection road image in monitoring subsystem A2 violating the regulations judges whether there is vehicle in Emergency Vehicle Lane, and this process is based on the visual identification algorithm of machine. If judging there is vehicle, carrying out next step and judging, namely judge that whether the vehicle in Emergency Vehicle Lane is the special car such as the vehicle carried out an urgent task and police car, fire fighting truck, breakdown lorry, ambulance or whether vehicle opens hazard warning flasher, if the special car carried out an urgent task then continues cruise and carries out next step monitoring. If taking Emergency Vehicle Lane vehicle to open hazard warning flasher, starting monitoring subsystem A2 violating the regulations and carrying out the collection of emergent image and gps data, in order to subsequent transmission carries out the arrangement of emergency relief to freeway management department A41. If not the special car carried out an urgent task and do not open hazard warning flasher and then send instructions to flight subsystem A1, unmanned plane is made to be reduced to certain altitude and start monitoring subsystem A2 violating the regulations and carry out the identification of the collection of image violating the regulations and the locking of car plate and license plate number. Meanwhile, gather gps data and draw road section information violating the regulations. The series of steps such as compression that the original image collected carries out image uses certain host-host protocol carry out point-to-point transmission or be transmitted by 3G/4G network by the wireless network of 2.4GHz together with license plate number violating the regulations and road section information violating the regulations. Following road information issues subsystem A4 by certain host-host protocol, the view data transmitted carries out decompression etc. and processes the data base being saved in freeway management department together with license plate number violating the regulations and road section information violating the regulations or show on road information distribution platform. Take Emergency Vehicle Lane vehicle if existing in above-mentioned flow process and open the situation of hazard warning flasher, then image information and section location information are sent to freeway management department A41 to facilitate bailout development by the step received by above wireless transmission.
