The vehicle flow detection module comprises a double photoelectric tubes and a phototransistor. The double photoelectric tubes are double photoelectric tubes TCR5000 sensor. The wireless infrared receiving module is in a CX20106A type. The singlechip microcomputer is a STC89C51 singlechip microcomputer. The intelligent traffic system takes the STC89C51 singlechip microcomputer as a control core, the external traffic flow detection module feeds the collected information back to a main control chip, and the main control chip analyzes and processes the collected information to adjust the change of the traffic light through procedures, thereby reaching the intelligent effect.

Description

Intelligent transportation system

Technical field

The utility model belongs to the traffic signals equipment technical field, relates to a kind of intelligent transportation system.

Background technology

Along with fast development of society, the traffic problems in city also become focus thereupon.How to allow traffic system more efficiently become a urgent day by day problem in order.Therefore, intelligent transportation system also will become the inexorable trend in a kind of epoch.

Existing traffic system all is to be time and the program that configures by the people, and the replacement speed of traffic lights is that setting value is inconvenient to change, and is not intelligent, and does not have the function of caution.

Summary of the invention

The purpose of this utility model provides a kind of intelligent transportation system, by the information that collects can the Based Intelligent Control traffic lights variation, and possess prompt functions.

The technical solution adopted in the utility model is, intelligent transportation system, the input end of single-chip microcomputer is connected with vehicle Flow Detection module and Radio infrared receiver module respectively, and the output terminal of single-chip microcomputer is connected with traffic lights display module, countdown display module and warning indicating module respectively.

Feature of the present utility model is that also the vehicle Flow Detection module comprises photoelectric tube and phototriode, and photoelectric tube is a photoelectric tube TCR5000 sensor.

The Radio infrared receiver module adopts the CX20106A type.

Single-chip microcomputer is the STC89C51 single-chip microcomputer.

Intelligent transportation system of the present utility model, with the STC89C51 single-chip microcomputer is the control core, outside vehicle Flow Detection module is given main control chip with the information feedback that collects, the variation of regulation and control traffic lights is analyzed and handled to main control chip by program to the information of collecting then, thereby reach the effect of intelligence.

Description of drawings

Fig. 1 is the circuit theory diagrams of the utility model intelligent transportation system.

Fig. 2 is the circuit diagram of vehicle Flow Detection module in the utility model.

Among the figure, 1. single-chip microcomputer, 2. vehicle Flow Detection module, 3. Radio infrared receiver module, 4. traffic lights display module, 5. countdown display module, 6. warning indicating module, 7. photoelectric tube, 8. phototriode.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

The circuit structure of the utility model intelligent transportation system, as shown in Figure 1, comprise single-chip microcomputer 1, vehicle Flow Detection module 2 and Radio infrared receiver module 3 are connected to the input end of single-chip microcomputer 1, and the output terminal of single-chip microcomputer 1 is connected with traffic lights display module 4, countdown display module 5 and warning indicating module 6 respectively.

The circuit of vehicle Flow Detection module comprises photoelectric tube 7 and phototriode 8 as shown in Figure 2 in the utility model, and photoelectric tube 7 is a photoelectric tube TCR5000 sensor, and the output of photoelectric tube 7 is connected to a pin of phototriode 8.Photoelectric tube 7 is constantly launched infrared ray, when the infrared ray that sends be absorbed be not reflected or return come more weak the time, phototriode 8 blocking-up, the pin of "+" utmost point is a high level at this moment, holding relatively with "-", back voltage comparator output terminal is a high level.Otherwise output terminal is a low level.

Radio infrared receiver module 3 adopts the CX20106A type.The photodiode that receives infrared signal becomes the infrared signal of receiving into electric impulse signal and sends into CX20106A.These signals become low level and hold output by OUT after preposition amplification, amplitude limit, bandpass filtering, inspection filter, integration and hysteresis relatively.

Single-chip microcomputer 1 is the STC89C51 single-chip microcomputer.The P2.0 of single-chip microcomputer 1, P2.1 pin are used for scanning the control vehicle Flow Detection module 2 of horizontal vertical two-way and the level variation of Radio infrared receiver module 3 outputs respectively; P1.0 ~ P1.5 pin is controlled the traffic lights display module 4 of horizontal vertical two-way respectively successively; P1.6,1.7 pins are indicating module 6 taking alarm respectively; P3.4 connects the output terminal of Radio infrared receiver module 3, and is effective when scans I O mouth is low level; Single-chip microcomputer 1 is controlled these IO by program.

The utility model intelligent transportation system, this system serves as the control core with the STC89C51 single-chip microcomputer, outside vehicle Flow Detection module 2 is given main control chip with the information feedback that collects, the variation of regulation and control traffic lights is analyzed and handled to main control chip by program to the information of collecting then, thereby reach the effect of intelligence.This system mainly contains following function: have the general utility functions of all traffic lights in the reality, and can be according to the variation of vehicle flowrate, from the action time of master regulation traffic lights; Can select infrared wireless remote control or manually control traffic lights and open, stop, reset; The indication of reporting to the police appears for the behavior meeting of making a dash across the red light.
