a Traffic Control System Using Inductiveloop Detector

 

This article introduces an intelligent traffic light controller based on loop ground-sensing coils, including a signal acquisition module buried under the ground surface of each lane at the intersection. It also includes a controller that can control the on and off time of traffic lights based on vehicle traffic. It can be extended to control traffic lights at multiple intersections, with high reliability, good electromagnetic compatibility, and can withstand noise and humidity. low cost solution for your Traffic light control corners or single way road control.

The system include the following products:
Vehicle loop detectors
Vehicle loop detectors use for detecting the vehicle passing the road lane, which send the data and signal to the controller, controller receive the signal, and promotes the display state of the LED traffic light through the central processing.
LED traffic light
Normally use JUTAI high flux LED traffic light Red+Green, 100mm/200mm size.
Another type is high flux LED traffic light Slow+Green, 200mm size.
It is suitable for barrier gate vehicle control system. We also accept customized one light or two lights.
Smart traffic controller
Different projects the controller program is different, We have customized several different projects for the customers. In fact, we only need our engineers to deal with the controller. Please communicate with our team about any project requirements

There are the client's successful project solutions:
Solution 1
1.The vehicles on the curve both exit and entrance.
Products list:
2pcs small traffic controller,
2pcs traffic LED light
2pcs dual channel loop detector
1pcs single loop detector
2pcs Warning light
1 unit barrier gate
loop cable and power line
2. Working principle:
When there is no vehicle on both sides, both sides show green light, when there is a car
When entering CH1B to CH2B (or when a car enters CH1Ato CH2A),The alarm W1(W2) sounds.
At this point the light LB remains green (LA remains green), while LA(LB) is composed of Turn red, no vehicles allowed, wait 3 seconds (6 seconds by dial code).
Set the selection. If the car continues in direction B (direction A), After a large number of vehicles are released, it is forced to switch to a red light and wait for 3 seconds (6).
If no vehicle passes in direction A (direction B) after seconds by the dial code, Both sides are in green light status.
Note: count when entering CH2B in direction B or CH2A in direction A As a notation.
Solution 2

1.The vehicles for three entrances and exits 
Products list:
3pcs small traffic controller,
3pcs traffic LED light
3pcs dual channel loop detector
1pcs single loop detector
3pcs Warning light
1 unit barrier gate
loop cable and power line
2. Working principle:
When there is no vehicle on the three sides, the three sides all show green light, when there is a car entering CH1B to CH2B, alarms W1 and W2 sound.
At this time, the light LB is still green, while LA and LC change from green to red,No vehicles allowed, wait 3 seconds (6 seconds by dial code).
If there are more cars in direction B, After a large number of vehicles are released, it is forced to switch to a red light and wait for 3 seconds (6).
If no vehicle passes in direction A and direction C after seconds (dial code).
All sides are green.
Note: count when entering CH2B in direction B or CH2A in direction A As a notation.

 Solution 3
1. For one entrance and one exit
Products list:
2pcs barrier gates
2pcs smart traffic light
4pcs single loop detectors
1pcs single LED light "SLOW"
1pcs traffic LED light "SLOW"+Green"
2. Working Principle:

When the car coming on the loop1, entry light 6 and exit light 5 shows SLOW.

After the car leave the loop 1, it will have 6s relay delay output.

After 6s, the light 5 and 6 will change to BLACK, light 2 Green. (the state of the light is determined by relay output or ground pressure)

Another side same working.
Solution 4
1 .For same entrance and exit
Products list:
1pcs barrier gate
1pcs UHF reader
1pcs smart traffic light controller
2pcs traffic lights
2pcs dual channel loop detectors
1pcs single loop detector
Uhf card or sticker
 Working Principle:
Entrance to Exit:
When the car on loop1, and trigger the card reader, reader will read the card ,if card is valid, S1 will be green, S2 become red,and barrier open.
When car on loop 2 the S1 become red and S2 will be remaining green .
When car passed loop 2, the S1 become green and S2 Remaining green.
If no car, the green color at entrance and exit always keep on.
Exit to Entrance:
When car on Loop2, the loop detector will trigger barrier open, S2 will be green, S1 become red.
when car on loop1,the S2 become red and S1 will be remaining green.
when car passed loop 1, the S2 become green and S1 Remaining green.
If no car, the green color at entrace and exit always keep on.

Solution 5
1. For one gate access
Product list:
1pcs traffic light
1pcs smart traffic controller
2.Working Principle:
When the car presses loop A, the IU is triggered and the red light is on
IU judge whether the car is registered or not, if it is invalid, the turn will not open, and keep the red light on; When the car leaves the red light, it goes out.
If valid, red light off, green light on
When the vehicle passes loop B, the road gate closes and the green light goes out.
