(2) Analyzing the speed of the users in the time section of the road section, and setting the proportion of the users to be chosen or rejecting the users or appointing the speed to be chosen or rejecting the users. The user rate is a value that the speed of the user on the road section is lower than the rate, and can be set to 0-100%.
(3) After determining the rate of accepting or rejecting users or the rate of accepting or rejecting, the anchoring rate is determined. The anchoring speed is the user speed in the user proportion.
(4) The switching time of the human eyes adapting to the two screens is set, and the switching time of the human eyes adapting to the two screens is recommended to be set to be not lower than the highest speed limit/anchoring speed of the road section by 1s due to the movement of people on the road, and the special environment (such as turning, ramp) and the like should be increased.
(5) Setting whether to turn on environmental factor switch
(6) And calculating the playing time delay of the display screens of the two adjacent lamp poles. The playing time delay is max (0, the distance between two adjacent lamp poles-the visual distance of the display screen)/the anchoring speed + the switching time of the two screens adapted by human eyes.
(7) Viewing blur distance: if two adjacent lamp pole distances > display screen visible distance, will have one section and watch fuzzy distance, two adjacent lamp pole distances watch fuzzy distance and do: the distance between two adjacent lamp poles is the visual distance of the display screen.
(8) Viewing blur time: the viewing blur distance/speed is the viewing blur time.

analyzing the speed of the user in a certain time period of the road section, and setting a user accepting and rejecting proportion or a designated accepting and rejecting speed; the user rate is set to be 0-100% when the speed of the user in the road section is lower than the rate; anchor speed = cut-off speed = user speed in cut-off user proportion.
4. The method as claimed in claim 3, wherein the method comprises the steps of: the specific setting of the human eye adaptive two-screen switching time is as follows:
the switching time of the set human eyes adapting to the two screens is set to be not less than the highest speed limit/anchoring speed of the road section by 1s, and the switching time of the human eyes adapting to the two screens in the special environment is increased.
5. The method of claim 1, wherein the method comprises the steps of: the setting whether to turn on the environmental coefficient switch specifically includes:
automatically adjusting the brightness of the LED screen according to the date, time, weather, the relative direction of the sun and the LED screen and the data of the light sensor, calculating an environment coefficient, wherein the environment coefficient acts on the optimal visible distance interval, and the optimal visible distance interval is enlarged or reduced; each factor of the environmental coefficient needs data accumulation and correction, and at present, the factor defaults to 1, and a switch is arranged, the current switch is closed, and the environmental coefficient = 1.
6. The method of claim 1, wherein the method comprises the steps of: the selected road section specifically comprises the following steps:
selecting user data of a certain time period of a road section, wherein the selected road section and the selected time period are self-defined, and road section identification is marked by an intelligent lamp pole number; type, display screen size, display screen height, the information of wisdom lamp pole position of every wisdom lamp pole LED screen are typeeed in the system.
7. The utility model provides a continuous play device of a plurality of wisdom lamp pole display screens which characterized in that: the method comprises the following steps:
the selection module is used for selecting a road section;
the system comprises a specifying module, a processing module and a processing module, wherein the specifying module is used for specifying a time period and analyzing user data of the time period;
the setting module is used for setting the proportion of accepting or rejecting users or the designated accepting or rejecting speed and determining the anchoring speed; setting the switching time of human eyes adapting to two screens; setting whether an environment coefficient switch is turned on or not;
the computing module is used for computing the playing time delay of the playing content of the intelligent lamp pole display screen;
wherein, calculate the broadcast time delay of wisdom lamp pole display screen broadcast content specifically does:
