Abstract

The utility model relates to an intelligent traffic light controlling device formed by a camera head (101), a DSP image processor (102), a one-chip microcomputer (103) and a display screen (104); the camera head (101) is connected with the DSP image processor (102); the DSP image processor (102) is connected with the one-chip microcomputer (103); the one-chip microcomputer is used for controlling the traffic lights and simultaneously driving the display screen (104); the DSP image processor (102) is used for processing images shot by the camera head (101), detecting traffic flow through certain algorithm, and sending traffic flow at present crossing to the one-chip microcomputer (103); and the one-chip microcomputer (103) adjusts time of the traffic lights according to the traffic flow. The intelligent traffic light controlling device is suitable for traffic lights management at crossroads, can automatically adjust time length of the traffic lights according to the traffic flow, thereby maximizing traffic passing volume at the crossroad, alleviating traffic obstructions, and bringing convenience to travelers and management personnel.

Description

The intelligent transportation lamp control device

Technical field

The utility model belongs to traffic communication and control field, relate to the intelligent transportation lamp control device, be specially adapted to crossroad access fluorescent tube reason, can adjust traffic lights time length automatically by vehicle flowrate, thereby make the traffic volume of crossroad reach maximization, alleviate traffic jam, bring convenience to traveler and supvr.

Background technology

The traffic lights design of crossroad is to alleviate traffic pressure, avoids traffic accident, and improves a kind of important means of traffic efficiency; Along with improving constantly of urbanization process, the expansion gradually of city scope, the crossroad is more and more in the quantity in city, and this just means that the people that drive to go on a journey will run into more traffic lights, waits for that current probability also can increase greatly.

Now the administrative mechanism of crossroad is the vehicle flowrate that adds estimation by statistics, thinks the length that the traffic lights time is set, this set at be this crossroad vehicle flowrate maximum the time, the resource that satisfies under the maximum traffic volume situation is distributed; In the time of but more, the crossroad does not present maximum vehicle flowrate, and thus, this traffic lights time control just seems not too reasonable.

At this situation in the daily life, the utility model design intelligent transportation lamp control device, the length of this device control traffic lights time is based on the detection to current crossroad vehicle flowrate, reasonably arranges transit time by certain algorithm, thereby makes utilization of resources maximization.

Summary of the invention

The purpose of this utility model is to design the intelligent transportation lamp control device, be used for crossroad access fluorescent tube reason, can adjust traffic lights time length automatically by vehicle flowrate, thereby make the traffic volume of crossroad reach maximization, alleviate traffic jam, bring convenience to traveler and supvr.

The technical solution of the utility model is: the intelligent transportation lamp control device, by camera, DSP image processor, single-chip microcomputer, display screen; Wherein, camera is connected with the DSP image processor, and the DSP image processor is connected with single-chip microcomputer, and the Single-chip Controlling traffic lights drives display screen simultaneously.

Above-mentioned intelligent transportation lamp control device is characterized in that display screen is used for the traffic lights countdown.

Principle of work of the present utility model is: camera is monitored traffic intersection and is taken pictures, and picture data is transferred to the DSP image processor, the DSP image processor is by certain algorithm process, and the auto model on the comparison film extracts statistics, thereby obtains current intersection vehicle flux; The DSP image processor is transferred to single-chip microcomputer with detected information of vehicle flowrate, and single-chip microcomputer determines currently whether should adjust the time of traffic lights by certain algorithm, thereby reaches the purpose of adjusting traffic intersection.

Description of drawings

Be further described below in conjunction with the utility model of enforcement figure:

Fig. 1 is the synoptic diagram of the utility model intelligent transportation lamp control device;

Among the figure: 101, camera; 102, DSP image processor; 103, single-chip microcomputer; 104, display screen.

Embodiment

As shown in Figure 1, be the utility model intelligent transportation lamp control device, comprising: camera 101, DSP image processor 102, single-chip microcomputer 103, display screen 104; Wherein, camera 101 is connected with DSP image processor 102, and DSP image processor 102 is connected with single-chip microcomputer 103, and single-chip microcomputer 103 control traffic lights drive display screen 104 simultaneously; DSP image processor 102 is for the treatment of the image of being taken by camera 101, by certain algorithm inspection vehicle flow, and current crossing traffic flow is transferred to single-chip microcomputer 103, and single-chip microcomputer 103 is adjusted the time of traffic lights by vehicle flowrate; Display screen 104 is used for the traffic lights countdown.

During use, two cameras 101 are separately fixed on two circuits of crossroad intersection, camera 101 is monitored two traffic intersections respectively and is taken pictures, and picture data is transferred to DSP image processor 102, DSP image processor 102 is by the detection algorithm based on model, auto model on the comparison film extracts statistics, thereby obtains current intersection vehicle flowrate; DSP image processor 102 is transferred to single-chip microcomputer 103 with detected information of vehicle flowrate, single-chip microcomputer 103 is by comparing vehicle flowrate, determine the current time that whether should adjust traffic lights after the analysis-by-synthesis, thereby reach the purpose of adjusting traffic intersection, and the traffic lights countdown at each crossing is presented on the display screen.

Above embodiment does not constitute any restriction to the utility model content to of the present utility model with reference to explanation, obviously under thought of the present utility model, can make multi-form structure modify, but these are all at the row of protection of the present utility model.
