Abstract

The utility model relates to an urban traffic signal system based on cooperative vehicle and infrastructure, which belongs to the technical field of traffic safety. The urban traffic signal system based on cooperative vehicle and infrastructure comprises a traffic light signal transmitting device arranged in a traffic light on the traffic crossing and a traffic light signal receiving device arranged in the vehicle. The present status that the road signal is judged by a driver only through the displaying state of the traffic light or the driving state of the vehicle ahead, is changed, and under the relevant procedure support, the information of the traffic light is displayed on the traffic light signal receiving device on the vehicle in a more intelligent and humanized way, thus the driver can more conveniently and accurately judge the road traffic status.

Description

A kind of based on the collaborative urban traffic signal system of bus or train route

Technical field

The utility model relates to a kind of based on the collaborative urban traffic signal system of bus or train route, belongs to the traffic safety technology field.

Background technology

At present, domesticly done a lot of related works about urban highway traffic, particularly along with the popularizing of onboard navigation system, road traffic progressively develops towards intelligent, hommization aspect.The road traffic system is also further perfect.But be faced with also simultaneously that vehicle is more and more, traffic safety, the more and more important difficult problem of driving efficient.In urban transportation, traffic pressure has been alleviated in the application of the job facilities such as viaduct, overpass to a great extent, but the traffic lights railway and highway system still is one of most important means of transportation in the urban transportation.Show that perhaps sight line is subjected to blocking of other oversize vehicles because the part traffic lights are not free, the perhaps factor such as inclement weather impact, the vehicle driver can not judge be open to traffic time or Waiting time effectively and timely, the impact driving is judged, has increased the weight of traffic pressure.

Summary of the invention

The purpose of this utility model provides a kind of collaborative commander of bus or train route who is used for the city intersection traffic light based on the collaborative urban traffic signal system of bus or train route.At vehicle more or traffic lights not free show or the situation of bad weather under the equal time information of passing through, wait of traffic lights is conveyed to the driver, make things convenient for the driver to judge driving.

The purpose of this utility model is achieved through the following technical solutions, a kind of based on the collaborative urban traffic signal system of bus or train route, the traffic lights that comprise traffic road junction different directions, it is characterized in that the traffic light signal receiving trap that arranges in the traffic light signal emitter that described traffic signal system is arranged by the traffic road junction and the vehicle consists of; Described traffic light signal emitter is comprised of wigwag and the traffic light signal transmitter of central processing unit, all directions traffic lights, the wigwag of all directions traffic lights connects the input end of central processing unit, the output termination traffic light signal transmitter of central processing unit; Described traffic light signal receiving trap is comprised of traffic light signal receiver, in-vehicle processor, display board and vehicle mounted guidance mechanism, the output of the output terminal of traffic light signal receiver, vehicle mounted guidance mechanism connects respectively in-vehicle processor, the output termination display board of in-vehicle processor.

Described central processing unit adopts AT89C51 type single-chip microcomputer.

Described in-vehicle processor adopts AT89C51 type single-chip microcomputer.

Described traffic light signal transmitter and traffic light signal receiver all adopt single-chip microcomputer radio receiving transmitting module DTD465 type.

Display board adopts the LMS700KF07 liquid crystal display.

The utility model has changed the driver can only be by the present situation of traffic lights show state or front vehicle travelling state judgement roadway sign, under the support of relative program, being presented on the signals of vehicles receiving trap of traffic lights information is more intelligent, hommization is convenient to that the driver is convenient to judge the road situation accurately.

Description of drawings

Fig. 1 is the utility model block diagram;

Fig. 2 is traffic lights emitter synoptic diagram;

Fig. 3 is signals of vehicles receiving trap synoptic diagram;

Among the figure, 1 traffic lights, 2 central processing units, 3 traffic light signal transmitters, 4 traffic light signal receivers, 5 vehicle mounted guidance mechanisms, 6 in-vehicle processors, 7 display boards.

Embodiment

Further specify the utility model with accompanying drawing in conjunction with the embodiments, as shown in Figure 1, the traffic light signal receiving trap that arranges in the traffic light signal emitter that the utility model is arranged by the traffic road junction and the vehicle consists of; Described traffic light signal emitter is comprised of wigwag and the traffic light signal transmitter 3 of central processing unit 2, all directions traffic lights 1, the wigwag of all directions traffic lights 1 connects the input end of central processing unit 2, the output termination traffic light signal transmitter 3 of central processing unit 2; Described traffic light signal receiving trap is comprised of traffic light signal receiver 4, in-vehicle processor 6, display board 7 and vehicle mounted guidance mechanism 5, the output of the output terminal of traffic light signal receiver 4, vehicle mounted guidance mechanism 5 connects respectively in-vehicle processor 6, and the output of in-vehicle processor 6 connects display board 7.

Take existing traffic lights 1 as chief component, central processing unit 2 gathers different directions traffic lights information and carries out collating sort according to different direction to the car notice signals, then process information is sent in the scope of 100-300m by traffic light signal transmitter 3, vehicle is when walking to this traffic lights scope, signals of vehicles receiver 4 can receive the signal that includes traffic lights information voluntarily, transfer to in-vehicle processor 6, according to the direction to the car of vehicle mounted guidance mechanism 5 judgement vehicles, in-vehicle processor 6 is selected the traffic lights information of needs and is shown through display board 7.

Principle of work: this traffic signal lamp is processed by central processing unit, traffic information to different directions is put in order, according to the crossing quantity blockette statistics of sending a car, by traffic light signal transmitter 4 signal is sent in the 100-300m scope of this crossing, the vehicle that travels to the 100-300m scope of this crossing will be by this signal of vehicle traffic light signal receiver 4 automatic receptions, and according to vehicle mounted guidance information, select the party to offer the driver to the traffic lights information of sending a car.Eliminate the not free demonstration of traffic lights or front truck and blocked the traffic safety hidden danger that traffic lights information or inclement weather etc. bring.

Vehicle mounted guidance mechanism 5 in the utility model adopts existing product.The power acquisition of traffic light signal emitter existing power supply circuit in the utility model, the traffic light signal receiving trap adopts vehicle power and existing power supply circuit in the utility model.
