Abstract

The utility model relates to a traffic light system capable of improving the vehicle passing efficiency. The traffic light system is mainly composed of a main controller, infrared sensors and traffic lights. A secondary road is provided with sensing areas. The infrared sensors are arranged in the sensing areas. Each infrared sensor is electrically connected with the main controller and provides a signal which indicates whether or not a body waiting for the green light is in the sensing area for the main controller. The traffic lights are electrically connected with the main controller and the main controller controls the traffic lights according to the signal. Because the secondary road is provided with the traffic condition monitoring devices, the provided secondary road information can be used as the basis of primary road release, the meaningless waiting of vehicles on the primary road is avoided, the energy is saved, and the driver mind is adjusted. The traffic light system is especially suitable for the crossroad in which the primary road is very different from the secondary road.

Fig. 2 is control principle drawing of the present utility model

Specific implementation method

Below with reference to accompanying drawing the utility model is described in further detail, but does not consist of any restriction of the present utility model.

Such as Fig. 1, shown in Figure 2, a kind of Novel traffic light system that improves main and secondary road intersection vehicle pass-through efficient, comprise traffic lights 1, traffic lights are major trunk roads 5, subsidiary road 6 provides right of way signal, be provided with induction zone 2 at subsidiary road, also comprise master controller 3, infrared ray sensor 4, infrared ray sensor 4 is used for monitoring and has or not the main body that waits for a green light in this induction zone 2, infrared ray sensor 4 is electrically connected and provides to master controller 3 signal that has or not the main body that waits for a green light in the induction zone with master controller 3, traffic lights 1 be electrically connected with master controller 3 and master controller 3 according to these signal controlling traffic lights 1, the time that green light shows on the main controller controls subsidiary road is B second, and the traffic lights on the main controller controls major trunk roads can show that the time of green light is by forming second basis time period X second and N time expand section Y; When this infrared ray sensor monitors in second when the main body that waits for a green light is arranged in the induction zone at basis time period X, then basis time period X drawer second completely after master controller control still that major trunk roads show green light until the full time expand section Y of drawer after second, the traffic lights that master controller is controlled on the major trunk roads again show that the traffic lights on red light and the control subsidiary road show green light B second; When the infrared ray sensor monitors in second when the main body that waits for a green light is arranged in the induction zone at time expand section Y, green light on the main controller controls major trunk roads continues to show Y second again, and the traffic lights that the completely rear main control of its drawer is controlled on the major trunk roads again show that the traffic lights on red light and the control subsidiary road show green light B second; When the infrared ray Sensor monitoring continues in the induction zone without the main body that waits for a green light and full N Y of time drawer that shows green light on the main controller controls major trunk roads after second, the traffic lights on the main controller controls major trunk roads show red light and control traffic lights demonstration B green light second on the subsidiary road.Particularly, choose 24, N with X and choose 6, Y and choose 12 for example, in front 24 seconds, as long as induction installation monitors the main body that waits for a green light is arranged in the induction zone on the subsidiary road, then completely postpone again to transfer on the subsidiary road in first 12 seconds red light after 24 seconds; Have the main body that waits for a green light then to postpone second subsidiary road after 12 seconds in the induction zone to transfer red light to as in first 12 seconds, monitoring ... the 3rd monitor in 12 seconds then four of delay controls after 12 seconds subsidiary road transfer green light to, by that analogy; Such as the main body of never waiting on the subsidiary road, green light i.e. 24 seconds+12 seconds * 6=96 after second after the 6th 12 on the major trunk roads then transfers red light to, subsidiary road transfers green light to and continues B second on the major trunk roads.Adopt and force to change traffic signals after this full N the time expand section and can avoid sometimes causing impassable phenomenon on the subsidiary road because the fault of uniting causes changing.In the present embodiment, induction zone is to be formed by the infrared ray sensor scope that monitoring can be covered to subsidiary road.As the direct distortion of present embodiment, X, N, Y also can choose other value.Wherein, the scope selected of N 2≤N≤6 preferably.The utlity model has and avoid vehicle in the characteristics of overhead grades of major trunk roads, energy savings, adjusting driver psychology, the especially suitable main and secondary road magnitude of traffic flow intersection that differs greatly.
