Abstract
The invention discloses an intelligent transportation system. The intelligent transportation system comprises a monitoring center, and further comprises a vehicle-mounted system, wherein the vehicle-mounted system is connected with the monitoring center through a wireless network; the vehicle-mounted system comprises a main controller, a GPS (global positioning system) module, input equipment, a display device, a signal processing circuit and an antenna; the GPS module, the input equipment, the display device and the signal processing circuit are connected to the main controller; the antenna is connected to the signal processing circuit. The intelligent transportation system has the advantages as follows: the intelligent transportation system is simple; the intelligent transportation system can display state information of road vehicles through the vehicle-mounted system so as to provide driving reference information for drivers, so that the drivers can timely regulate respective driving routes conveniently, and the road congestion is effectively reduced.
Description
Technical field
The present invention relates to field of traffic control, relate to a kind of intelligent transportation system in particular.
Background technology
Automobile since being born at the end of last century, more than 100 year of the trials and hardships of having passed by.Step into 21 century, along with continuous development and the growth in the living standard of science and technology, the popularity rate of automobile is more and more higher, and the thing followed is that road traffic also more and more blocks up.Cause the reason of traffic jam to have a lot, main cause is that travel time overlapping makes that the vehicle flowrate in some node area of transportation network is excessive, surpasses the peak load of this node.But the vehicle load in some highway section is also little, and this just causes the vehicle problem of uneven distribution.The what use is made of intelligent transportation system is dredged the traffic of blocking up or is guided, and a kind of traffic control system of real-time demonstration transport information is provided, and the smooth and easy communication of traffic is had important effect.
Summary of the invention
The invention provides a kind of intelligent transportation is, its system is simple, the information status of road vehicle can be shown by onboard system, for human pilot is provided by the steered reference information that provides, be convenient to human pilot and in time adjust the traffic route of oneself, effectively reduce the congestion in road problem.
For solving above-mentioned technical matters, the present invention by the following technical solutions:
Intelligent transportation system, it comprises Surveillance center, also comprise onboard system, described onboard system is connected by wireless network with Surveillance center, described onboard system comprises master controller, GPS module, input equipment, display device, signal processing circuit and antenna, described GPS module, input equipment, display device and signal processing circuit all are connected on the master controller, and described antenna is connected on the signal processing circuit.
Further technical scheme is:
Described display device is LCD.
Described Surveillance center comprises display device and warning device.
Described warning device is hummer or audible-visual annunciator.
Described master controller comprises chip MC9S12DG128.
Described signal processing circuit comprises A/D change-over circuit and D/A change-over circuit.
Compared with prior art, the invention has the beneficial effects as follows: system architecture of the present invention is simple, and can show by the real-time information of onboard system with road vehicle, be convenient to human pilot and in time adjust the traffic route of oneself according to traffic information, reduce the situation of traffic congestion.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is structured flowchart of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.Embodiments of the present invention include but not limited to the following example.
[embodiment]
Intelligent transportation system as shown in Figure 1, it comprises Surveillance center, also comprise onboard system, described onboard system is connected by wireless network with Surveillance center, described onboard system comprises master controller, GPS module, input equipment, display device, signal processing circuit and antenna, described GPS module, input equipment, display device and signal processing circuit all are connected on the master controller, and described antenna is connected on the signal processing circuit.
Described display device is LCD.
Described Surveillance center comprises display device and warning device.
Described warning device is hummer or audible-visual annunciator.
Described master controller comprises chip MC9S12DG128.
Described signal processing circuit comprises A/D change-over circuit and D/A change-over circuit.
The course of work of present embodiment is as follows:
Onboard system of the present invention is fixed on the automobile, the GPS module positions the positional information of vehicle and positional information is sent to master controller, master controller is sending to signal processing circuit with positional information, process digital signals into the simulating signal that is fit to the antenna transmission, and send to Surveillance center by antenna.Surveillance center shows information of vehicles on the road by display device, when monitoring center monitors the vehicle load in certain highway section when excessive, report to the police by warning device, give the staff of Surveillance center to remind, so that it in time takes measures to alleviate the traffic of blocking up.Surveillance center can send to onboard system with the information of vehicles in vehicle peripheral highway section of living in, after the antenna of onboard system receives information, by signal processing circuit with analog signal processing for being fit to the digital signal that master controller is handled, and show by the traffic information of display device with periphery, so that human pilot is according to the traffic route of traffic information adjustment in time oneself, to reduce the problem of traffic congestion.Input equipment is used for the human pilot input and wants the highway section understood, by antenna the information that the driver wants to understand certain highway section is sent to Surveillance center, and Surveillance center feeds back the traffic information in this highway section again to onboard system.
Be embodiments of the invention as mentioned above.The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
