Embodiment:
As shown in Figure 1, suppose in the A in city cross traffic main artery generation traffic jam, and numbering 100 arranged simultaneously at the A place, 102,103,104,105 vehicle, these vehicles all are equipped with the device that the unit described in of the present invention constitutes, numbering 100,102,103,104,105 vehicle can be simultaneously the speed that outwards sends this vehicle ' that obtains by GPS according to a certain order, and this speed has reason to think (exception is arranged also certainly owing to what traffic jam caused, about this problem further instruction is arranged in the back), be numbered 100 vehicle as setting and obtain this information at first, and with outside general the broadcasting of this information, and at this moment the vehicle in the effective radius of its transmitting range all can receive this information, as number 102,103,104,105 vehicle is all in this radius, and all receive this information, they can compare the information of reception and the information of having stored of memory cell, when memory cell does not have the information inconsistency of record or record, store this information, this information comprises the time, the place, car number; The vehicle of numbering 102,103,104,105 not only stores these information, and again the information that receives is continued outwards to propagate simultaneously.That is to say, at this moment there is a vehicle to continue to propagate this information earlier at first, as number 102 vehicles and propagate earlier, at this moment, having stored for numbering 103,104,105 vehicle has this information, and therefore, they can not carry out record to this information again, and when waiting until own transmitting time, the transmission task of finishing oneself gets final product.After numbering the propagation of 102 vehicles, vehicle 108,107 at a distance will receive this information, it is the same with the course of work of the vehicle reception information of above-mentioned numbering 102,103,104,105 equally, is record and storage information on the one hand, continues propagation by self more on the other hand; 106 can continue to finish above-mentioned task on following E road, and by 109 receptions on the E road, all vehicles receive and maybe can receive this information up to the incity, city again.
Certainly, the wireless transmitting unit of the vehicle of numbering 102,103,104,105 is when diffusing information, send information and can not produce interferences in order to be implemented in different time, areal (because there are a plurality of wireless transmitting unit transmission information same time, same place, can form and disturb), can whether there be the information of approval to exist by detecting radio receiving unit earlier, when not receiving the signal message of approval, just outwards send above-mentioned information signal as this moment; Its two mode that can adopt timesharing to propagate, just the processing unit of each control wireless transmitting unit all can be worked under the coordination of synchronised clock, does not allow the different automobile wireless transmitter unit of numbering be in same time service.A kind of effective way of precision problem that solves synchronised clock is that carry out synchronously in the high precision clock source that utilizes gps system to provide.
Influence the reception of wireless messages when not making emission information, the module that radio receiving unit and wireless transmitting unit can adopt stand-alone integrated circuit to constitute.Certainly under impregnable situation of time, radio receiving unit and wireless transmitting unit also can adopt can send out the monolithic integrated circuit that can receive.
The information that needs only reception in above-mentioned information communication process, even received this information, also no longer continued to send when this vehicle had sent this information through confirming.
In above-mentioned information communication process, the traffic jam information that receives a vehicle transmission can not think to be exactly that obstruction has taken place in described geographical position, has sent such information and need receive a plurality of vehicles simultaneously in the same period.Certainly, their car number difference.As the vehicle that numbering 100,102,103,104,105 is arranged simultaneously at the A place that is beginning to describe, at first by numbering 100 vehicle detection to the information that is considered to traffic jam, 102,103,104,105 vehicle will detect the information of traffic jam one by one subsequently, and will be to sending at a distance, vehicle 109,106 when at a distance receive simultaneously 102,103,104,105 send information the time (as set have 5 cars to send the information of same place, same time period the time), show that traffic jam information has taken place to provide this area.
When traffic jam takes place, very serious sometimes, not very serious sometimes, in order to describe the order of severity of described traffic jam information, can provide the order of severity amount of traffic jam information jointly by Vehicle Speed and this travel speed holding time.As a certain place of 6 vehicles at a certain route arranged in 10 fens kinds, only travelled 100 meters; And the another place of another time had a certain place of 6 vehicles at a certain route in 10 minutes in the kind, had only travelled 10 meters; Therefore their the traffic jam order of severity is different; Therefore be necessary to provide the value of the order of severity of traffic jam information for distinguishing them, this value can provide by the size of a byte, the order of severity of traffic jam information will be divided into 256 situations like this, certainly, actual classification can be carried out with reference to the traffic administration pertinent regulations.
Among the present invention in order to detect the travel speed of vehicle so that determine whether to take place traffic jam, the time period notion of introducing, the operating range that is to say the vehicle with how long at interval is as judgment basis.Generally in urban transportation, the red time of traffic cross is the longest to reach 1 fen more than the kind, and therefore, the above-mentioned time interval is greater than 2 fens kinds at least.And operating range can be examined the minimum resolution of filter GPS, also will examine the filter travel speed.Relatively poor GPS receiver module has only 14 meters or higher.Thereby whether definition traffic jam information takes place will be selected more than 5 minutes at least, and the vehicle ' distance is less than 50 meters values as a kind of order of severity of traffic jam information.
General in a city through regular meeting in some hotels, hotel or other public place of coming in and going out easily assembles a lot of vehicles, particularly taxi.If there is the vehicle of sufficient amount that device of the present invention is installed in these vehicles, the vehicle of gathering can provide the information identical with The above results, as to these information of receiving without analyse, will produce wrong traffic jam information.
As shown in Figure 2, G represents hotel, hotel or other public place of gathering easily, has at the G place to be numbered 203,205,206 vehicle, and G is again on a highway limit, be numbered 203,205,206 vehicle as being parked in the G place, can give the traffic jam information that makes mistake; Therefore, among the present invention, vehicle detection to the speed of a motor vehicle in a certain geographical position when being lower than a certain value, also to confirm the geographical position at place, not need to detect car speed as in prior program, having set this position, at this moment, be lower than a certain value even detect the speed of a motor vehicle, also do not carry out emission information.Can solve the problem that wrong traffic jam information occurs preferably by such definition.
Know where traffic jam takes place, the traffic jam area take place be eased that this information also will blaze abroad timely as traffic.This vehicle that just needs the traffic jam area to send block information constantly detects the travel speed of vehicle, again traffic jam alleviation information is sent regularly.Certainly send traffic jam and alleviated information and send at first not necessarily that those vehicles of traffic jam information send, it also may comprise other vehicle.In any case but the vehicle that sends traffic jam information constantly detects Vehicle Speed, after the traffic jam situation that detects this area has been eased, in time traffic jam alleviation information is sent again.
How many vehicles a city needs described device is installed at least, and it is fixed to come according to the area in city, and the wireless transmitting unit communication distance of general vehicle is between 300 meters-1000 meters.There are 100 square kilometres as a medium-sized city,,, just can set up the urban transportation information network as long as 1000 cars are arranged by adorning described device by 300 meters one.As shown in Figure 3, on a road, have two to be numbered 301 and 302 vehicle, their distances are D, and therefore when system design, communication distance D is between 300 meters-1000 meters.
In the city, set up the network described in the present invention by vehicle is highdensity, can set up the administrative center of control whole city transport information anywhere, it does not need to set up powerful wireless transmitting system, just can realize controlling each vehicle functions.Send as the vehicle in the city where road is carried out one-way road, where increase road etc.These information can send by different orders, are continued to propagate to other vehicle by nearest vehicle then.When these information of propagation, processing unit can be taked different priority treatment according to different command, propagates chronologically with guarantee information.
Certainly in the city of setting up network, any vehicle of device of the present invention that is equipped with is when the safety of oneself is subjected to danger, can send calling for help information to other vehicle by pressing emergent keyboard, other vehicle also can constantly be propagated this information after receiving this information, after this information sends to an administrative center, send distress signals to 110 by administrative center.The priority of calling for help information should be the highest.Distress signals comprise position, car number, send information time.Distress signals also can provide moving direction information, and this need work as processing unit when detecting emergency key, and the detection of completing place, the detection of moving direction send information then simultaneously.
