Abstract
The utility model belongs to the field of traffic lights, and particularly relates to an automatic switchover device for the time of traffic lights. The automatic switchover device is characterized in that the device at least comprises traffic lights, a vehicle speedometer detection device and a processing unit arranged on passages controlled by the traffic lights, and the processing unit continuously detects the vehicle flow and the speed information given by the vehicle speed detection device arranged on the cross passages; when the vehicle flow of a direction within a certain distance is more than 3 times larger than that of the other direction within a certain distance, the processing unit controls the traffic lights to ensure that the green time of one passage with lower vehicle speed is longer that that of the other passage; and when the traffic in one direction is jammed whereas the vehicle flow in the other direction is rare, the device can realize automatic time adjustment of the traffic lights.
Description
Technical field
The utility model belongs to the traffic lights field, particularly traffic lights time automatic switching control equipment.
Background technology
All be changeless traffic lights switching time of crossroad, city mostly, traffic hazard appears in the vehicle in the time of many on direction, cause this direction vehicle to stop up, vertical direction then traffic is normal, but the traffic lights of two vertical direction are still identical switching time, the vehicle that is easy to form a direction is quite a lot of, can't move ahead, and a direction is then gone everywhere without any hindrance here.Adopting image recognition to carry out transport information identification, be the feasible scheme of a kind of theory, but the problem that implements is many, because uncertain factor is too many.
The utility model content
The purpose of this utility model provides a kind of traffic lights time automatic switching control equipment, so that can stop up at a certain direction vehicle, and the other direction vehicle flowrate realizes adjusting automatically the traffic lights time seldom the time.
The purpose of this utility model is to realize like this, design a kind of traffic lights time automatic switching control equipment, it is characterized in that: which comprises at least traffic lights, vehicle speed pick-up unit and the processing unit arranged on the traffic lights control channel, processing unit constantly detects vehicle flow and the speed information that the vehicle speed pick-up unit arranged on the cross passage provides, vehicle in the vehicle of a direction in the stretch journey surpasses other direction stretch journey is more than 2 times the time, and processing unit control traffic lights make the time of the slow passage green time of flow velocity greater than another passage green light.
Described vehicle speed pick-up unit is to constitute by underground inductive coil and testing circuit that stretch journey before and after passage is provided with, and testing circuit offers processing unit by the vehicles passing in and out number that coil before and after detecting detects.
Described vehicle speed pick-up unit is that stretch journey vehicles passing in and out number offers processing unit before and after detecting by Flame Image Process by the video camera in the stretch journey setting of passage front and back.
The utility model has the advantages that: the utility model is owing to the stretch journey at different directions is provided with the vehicle speed pick-up unit, by the vehicle number in the stretch journey that detects different directions, by the vehicle fleet size in the stretch journey of different directions is compared, vehicle in the vehicle of a direction in the stretch journey surpasses other direction stretch journey is more than 2 times the time, processing unit control traffic lights make the time of the slow passage green time of flow velocity greater than another passage green light, realize adjusting automatically the traffic lights time, alleviate because the traffic jam that miscarriage causes.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment:
Fig. 1 is the utility model embodiment 1 structural representation.
Among the figure: 1, north and south traffic lights; 2, north and south second inductive coil; 3, thing highway section; 4, thing first inductive coil; 5, north and south first inductive coil; 6, highway section, north and south; 7, thing second inductive coil; 8, thing traffic lights.
Embodiment
As shown in Figure 1, as on the highway section, north and south 6 north and south first inductive coil 5 and north and south second inductive coil 2 being set at the parting of the ways, thing first inductive coil 4 and thing second inductive coil 7 are set on the thing highway section 3 at the parting of the ways.North and south first inductive coil 5 and north and south second inductive coil 2 detect the vehicle fleet size in highway section, north and south 6, thing first inductive coil 4 and thing second inductive coil 7 detect the vehicle fleet size in thing highway section 3, when highway section, north and south 6 when the vehicle fleet size in thing highway section 3 is more than 2 times, processing unit control north and south traffic lights 1 green time is greater than thing traffic lights 8.On the contrary, when highway section, north and south 6 when the vehicle fleet size in thing highway section 3 is more than 2 times, processing unit control north and south traffic lights 1 green time is less than thing traffic lights 8.
As different from Example 1, highway section, north and south 6 and thing highway section 3 respectively are equipped with video camera at the parting of the ways, by camera review processing detection highway section, north and south 6 and thing highway section 3 vehicle numbers are offered processing unit.Same when highway section, north and south 6 when the vehicle fleet size in thing highway section 3 is more than 2 times, processing unit is controlled north and south traffic lights 1 green time greater than thing traffic lights 8.On the contrary, when highway section, north and south 6 when the vehicle fleet size in thing highway section 3 is more than 2 times, processing unit control north and south traffic lights 1 green time is less than thing traffic lights 8.
Claims (3)
