Further, described to include wirelessly:Bluetooth, infrared, ZigBee.
The utility model has the beneficial effects that:The intelligent traffic light safety of the utility model is good, is conducive to vehicle saving
Stand-by period and quickly through.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment 1.
Fig. 2 is the scheme of erection of the utility model embodiment 2.
In figure:1. three color alternating lights, 2. shadow detection device, 3. searchlighting camera.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the utility model embodiment.
Embodiment 1
As shown in Figure 1, the intelligent traffic light of the utility model includes:Three color alternating lights 1, shadow detection device 2.
The three colors alternating light 1 and control unit signal transmission, and receive the command signal of described control unit transmission.Tool
Body, the mode of the signal transmission can be wired or wireless.Wherein, the three colors alternating light 1 and described control unit
When being connected by wired mode, the two is connected by traffic lights control line;The three colors alternating light 1 is logical with described control unit
When crossing wireless mode connection, the two can be connected by the modes such as bluetooth, infrared, ZigBee.
Described control unit sends command signal to the three colors alternating light 1, and controls the display of the three colors alternating light 1
State and display time.Specifically, described control unit includes control circuit and timing circuit, wherein the control circuit control
Make the dispaly state of the three colors alternating light 1, vehicle on this road that the timing circuit is detected by shadow detection device 2
How many information, controls the display time of the three colors alternating light 1, in this way, avoid other side's road also and have vehicle passage, when waiting
Between long problem.
Whether the shadow detection device 2 is for detecting on corresponding track with the presence of vehicle.Specifically, the shadow detection
The time lamp region setting at crossing where device 2 corresponds to three color alternating light of the intelligence, 1 system, the shadow detection device 2 and the control
Cell signal transmission processed.To, in the presence of shadow detection device 2 detects and has vehicle on a number of shadow detection device 2,
Detectable signal can be sent to described control unit.Control unit carries out the vehicle fleet size on the shadow detection device 2 in each track
After comparison, further, the shadow detection device 2 limits the size of search coverage.And be correspondingly arranged at any parking area
At least 3 in shadow detection device 2, spacing between any two can accommodate 2-5 vehicle and stop, at the parking area of a walkway
All shadow detection devices 2 be connected in series with, when the signal that concatenated all shadow detection devices 2 are transferred to control unit is vehicle
When more, the vehicle fleet size signal that control unit is transmitted in the shadow detection device 2 for being collected into other each parking areas,
In the case that a whole periodic signal lamp time span is constant, control unit is by three colors corresponding to the parking area more than vehicle
The time synthesis of 1 green light of alternating light adjusts length, the time of few corresponding three color alternating lights, 1 green light of vehicle fleet size of parking area
It is comprehensive to adjust short, reach and allows the channel more than vehicle or the few channel of vehicle as far as possible, the time phase difference that each vehicle all waits for parking
Diminution or even equality.If being obtained according to the detectable signal of shadow detection device 2, all without vehicle on the several channels of a direction, then
The green light of a whole periodic signal lamp time span is all adjusted to going on other roads more than vehicle, shadow detections device 2 is waited
, will be since next periodic signal lamp time span when transmitting out existing vehicle herein, it is suitable to be equipped with to the channel in this direction
Green time.
In conclusion the intelligent traffic light safety of the utility model is good, is conducive to vehicle and saves stand-by period and quickly
Pass through.
Embodiment 2
Fig. 2 gives the scheme of erection of the utility model embodiment 2, and in the present embodiment, unit provides each item in order to control
The how many information of vehicle on runway is detected by the searchlighting camera 3 being arranged above each three colors alternating light 1 and is provided, described
Searchlighting camera 3 is only limitted to the quantity information of vehicle on the corresponding runway in detection place, and detection length is set as 50 meters, then respectively
Processing of the information that a searchlighting camera 3 is detected Jing Guo control unit instructs the driving of all directions within the same period
The green time more than vehicle that road waits for lengthens, and the green time that the vehicle fleet size of waiting is few shortens;Without waiting for vehicle side
To green time can be adjusted to 0, by extra green time all leave for wait for vehicle more than direction;Realize crossroad
Vehicle waits for and the reasonable dredging of passing intelligent.
The utility model is illustrated by specific implementation process, in the case where not departing from the scope of the utility model,
Various transformation and equivalent substitute can also be carried out to the utility model.It is all that unsubstantiality is carried out to the utility model using this design
Change, should all fall into the utility model protection range.
