Optimum.
Brief description of the drawings
Fig. 1 is the schematic diagram of this intelligent mobile traffic lights.
During Fig. 2 is this intelligent mobile traffic lights, one embodiment schematic diagram of vehicle detection apparatus.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
In the embodiment shown in Fig. 1, Fig. 2, the intelligent mobile traffic lights includes pedestal 1；The top of pedestal 1 is provided with lamppost
2, four sides of the lamppost 2 are respectively equipped with three kinds of traffic lamp holders 3 of red, yellow, and green；Handed in the pedestal 1 or lamppost 2 provided with described
The control module of logical lamp holder 3（It is not shown）；Four sides of the lamppost 2 further respectively have a vehicle detection apparatus 4；The vehicle
Detection means 4 exports a count signal when often detecting a vehicle by lamppost 2 to the control module；The control
What molding block controlled each traffic lamp holder 3 as follows lights duration：Using mutually back to two vehicle detection apparatus as A
Group, the time interval of the two neighboring count signal exported to A group vehicle detection apparatus is stochastic variable A, and A groups vehicle is examined
Survey device and continuously take N（0<N<10）Individual count signal, obtains stochastic variable A desired value E（A）；Simultaneously with remaining two cars
Detection means is B groups, and the time interval of the two neighboring count signal exported to B group vehicle detection apparatus is stochastic variable
B, M is continuously taken to B group vehicle detection apparatus（0<M<10）Individual count signal, obtains stochastic variable B desired value E（B）；Make A groups
The red light in track direction that vehicle detection apparatus is detected lights the track side that duration and B group vehicle detection apparatus are detected
Ratio=the E for lighting duration of upward red light（A）/ E（B）.
Here, stochastic variable A averages are smaller, then it is assumed that vehicle density is larger, on the contrary, it is believed that vehicle density is smaller；Equally,
Stochastic variable B averages are smaller, it is believed that vehicle density is larger, otherwise think that vehicle density is smaller；Make vehicle density compared with bridle road, it is red
Lamp duration is smaller, e.g., makes E（A）Value and the red light in the track corresponding to A group vehicle detection apparatus to light duration proportional；
Make E（B）Value and the red light in the track corresponding to B group vehicle detection apparatus to light duration proportional；Therefore, examine A groups vehicle
Survey the lighting in the track direction that duration is detected with B group vehicle detection apparatus of the red light in the track direction that is detected of device
Ratio=the E for lighting duration of red light（A）/ E（B）, that is, make it that the big track of vehicle density is waited red light, vehicle density is small
Waiting red light more in the track；Meet the principle of traffic order optimization.
In addition, the duration of lighting of the red light in the track direction that the A groups vehicle detection apparatus is detected is examined with B groups vehicle
The duration of lighting for the red light surveyed in the track direction that device is detected is respectively provided with lower limit T1 and higher limit T2, in order to avoid occur extreme
Situation；Also, when A groups vehicle detection apparatus not yet takes N number of count signal, just exceedes the higher limit T2, then
The duration of lighting of the red light in the track direction that A group vehicle detection apparatus detected is set to be set to higher limit T2；Equally, when B group cars
Detection means not yet takes N number of count signal, when just exceeding the higher limit T2, then makes B group vehicle detection apparatus
The duration of lighting of the red light in track direction detected is set to higher limit T2.The lower limit T1 can be set to 10s, the upper limit
Value T2 can be set to 100s.
In the present embodiment, the vehicle detection apparatus is described as shown in Fig. 2 including towards the outside work durm 41 of lamppost 2
The inside inner end of work durm 41 is fixed with and the work durm is coaxial, axial magnetized permanent magnetism post 42；In the work durm 41 at forward end
It is fixed with the induction coil 43 for being orthogonal to work durm axis；The Sequential output of induction coil 43 to amplification module, AC/DC change
Device, during so as to produce an inductive impulse in the induction coil, exports a high level by the AC/DC converters and is used as institute
State count signal.
Thus, only in face of the car body of the port of the work durm 41, obvious magnetic could be formed with the permanent magnetism post 42
Power, so as to change the Distribution of Magnetic Field at the external port of the work durm 41（Strengthen magnetic field）, so that the induction coil 43 produces sense
Answer pulse；And the car body of the side of work durm 41, then due to the magnetic screening action of work durm, it is difficult to form obvious magnetic to the permanent magnetism post 42
Suction, it is difficult to change the Distribution of Magnetic Field in work durm 41；
Above-mentioned intelligent mobile traffic lights is located at crossroad middle position, in the course of the work, crossroad can be detected in real time
Traffic state on two current directions, and make the red light stand-by period on the less track of vehicle density longer, and wagon flow is close
The red light stand-by period on the larger track of degree is shorter, so that traffic order is optimized to optimum.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification for being made, equivalent substitution should be included in the scope of the protection.
