Description
Technical field
The utility model relates to traffic grade field, particularly relates to a kind of traffic lights delays time to control device.
Background technology
For now, along with increasing of vehicle, traffic jam has been a difficult problem for China's traffic. Traffic lights it be a kind of equipment of intelligence commander's traffic, but the stationarity due to the traffic lights time, and to wagon flow amount without detection function, it is easy to when wagon flow amount is bigger like this form traffic jam, even sometimes, there is traffic lights, but also want traffic police to releive traffic, very inconvenient like this.
For single file passage arranges walkway and traffic lights device, owing to the traffic lights device time arranges fixing, like this, even if there is no pedestrian or fewer in number time, if reaching red light setup times, vehicle will stop, thus cause traffic jam to increase further.
Practical novel content
In view of this, the purpose of this utility model is to provide a kind of traffic lights delays time to control device, when traffic lights switch, if flow of the people walkway being detected postpones switching time more at least, make vehicle leading, thus emergency traffic congestion.
The utility model is solved the problems of the technologies described above by following technique means:
A kind of traffic lights delays time to control device, comprises traffic light controller, traffic lights switching circuit and traffic lights, and described traffic light controller is connected traffic lights switching circuit and traffic lights successively; Its key is: be parallel with the first switch and the 2nd switch between described traffic light controller and traffic lights switching circuit, described first switch first termination traffic light controller, traffic lights switching circuit described in its 2nd termination;
Described 2nd switch first termination traffic light controller, its 2nd end series connection time delay unit, described time delay unit connects traffic lights switching circuit;
Also comprising population flow detection device, described population flow detection device output terminal is connected to the first switch and the action coil of the 2nd switch respectively.
Its effect is: when population flow detection device detects that flow of the people is less, then connection in order to switch between traffic lights switching circuit and traffic light controller, when flow of the people is more, traffic light controller is directly connected with traffic lights switching circuit by the first switch, then switch to traffic light controller when flow of the people is less to be connected with traffic lights switching circuit by time delay unit and the 2nd switch, thus alleviate flow of the people less time automobile blocking.
Further, described first switch is normally closed relay switch, and described 2nd switch is normal open relay switch.
Further, described population flow detection device comprises sensor, counter and comparer, and described sensor, counter and comparer are connected successively, and described comparer is connected to the first switch and the action coil of the 2nd switch respectively.
Preferably, described sensor is the one in infrared sensor, radar sensor and pressure transmitter; Use these sensors can calculate the flow of the people at People's Bank of China road junction at that time accurately.
Further, the time-delay action of described time delay unit is 5 to 10 seconds.
The beneficial effects of the utility model: by increasing a switching circuit with detection device between traffic lights control switching circuit and traffic light controller, if when flow of the people is less, then postpone the switching time between traffic lights, thus alleviate the blocking of automobile, the efficient scheduling situation of careful traffic congestion.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is connection diagram of the present utility model;
Fig. 2 is the connection diagram that the utility model is detailed.
Embodiment
Below with reference to accompanying drawing, the utility model is described in detail:
As shown in Figure 1:
A kind of traffic lights delays time to control device, compare with the traffic light control device of routine, specifically being provided with traffic light controller 1 in the present embodiment, in order to the switching time controlled between traffic lights traffic lights, the control of traffic light controller 1 is consistent with the controller of conventional traffic lights for switching time;
Above-mentioned traffic light controller 1 is the switching being realized traffic lights 3 by traffic lights switching circuit 2, instead of the switching of traffic lights 3 is directly controlled by traffic light controller 1, the output switching instruction of traffic light controller 1, to traffic lights switching circuit 2, realizes the switching of traffic lights 3 by traffic lights switching circuit 2;
In the present embodiment in order to alleviate walkway flow of the people less time the blocking up of vehicle, therefore two change-over switches in parallel between traffic light controller 1 and traffic lights switching circuit 2;
Article 1, branch road comprises the first switch 4, first switch one termination traffic light controller 1, another termination traffic lights switching circuit 2, and the type of this first switch 4 is normally closed relay switch;
Article 2 branch road comprises the 2nd switch 5 and time delay unit 5, connect between 2nd switch 5 and time delay unit 5, another termination traffic light controller 1 of 2nd switch 5, the type of the 2nd termination traffic lights switching circuit the 2, two switch 5 of time delay unit 5 is normal open relay switch;
In order to realize the first switch 4 and the control of the 2nd switch 5, being also provided with population flow detection device 7 in the present embodiment, the output of this population flow detection device 7 connects the first switch 4 and the control coil of the 2nd switch 5 respectively; Once population flow detection device 7 exports high level, switch the first switch 4 and the state of the 2nd switch 5, if output lower level first switch 4 and the 2nd switch 5 are failure to actuate;
As shown in Figure 2:
Above-mentioned population flow detection device 7 comprises sensor 71, counter 72 and comparer 73; Connecting successively between sensor 71, counter 72 and comparer 73, the output data of comparer 73 connect the first switch 4 and the control coil of the 2nd switch 5 respectively; The data of detection are passed to the comparison end of comparer 73 by sensor 71 after counter 72 counts, the benchmark termination preset value of comparer 73, this preset value can be arranged according to the people flow rate statistical in section, when the data of counter 72 are greater than benchmark value, now mean that flow of the people is bigger, comparer 73 exports lower level, and the first switch 4 and the 2nd switch 5 are failure to actuate, and traffic lights 3 normally switches; When being less than benchmark value when the data of counter 72, now meaning that flow of the people is less, comparer 73 exports high level, the first switch 4 and the 2nd switch 5 action, and traffic lights 3 time delay switches; Wagon flow amount according to this section and people flow rate statistical, the preset value of time delay unit 5 can freely set, and is generally arranged on 5 seconds to 10 seconds for best.
Can having multiple choices in order to detect the sensor 71 of flow of the people in the present embodiment, infrared sensor, radar sensor and pressure transmitter can detect the data of flow of the people accurately.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to better embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, and not departing from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
