Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, the intelligent street lamp display screen synchronous display method provided by the present application can be applied to the application environment shown in fig. 1. Wherein, the synchronous control terminal 102 communicates with the control platform 104 through the network. Each synchronous control terminal 102 is in communication connection with the intelligent street lamp display screen 106. The synchronization control terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. In one embodiment, the synchronization control terminal 102 may be an intelligent gateway, and the intelligent gateway and the intelligent street lamp display 106 may be connected by wire. The control platform 104 may be a computer device, server, or the like. The smart street lamp display 106 may be an LED display or other display.
Referring to fig. 2, in an embodiment, an intelligent street lamp display screen synchronous display method is provided, which is applied to the control terminal in fig. 1, and the control terminal is an intelligent gateway for example, and the method includes the following steps:
and S10, acquiring the video to be displayed.
The to-be-displayed video refers to video data needing to be displayed by the intelligent street lamp display screen. The video to be displayed has a certain playing time. The video to be displayed can be issued to the intelligent gateway by the control platform, and the intelligent gateway receives the video to be displayed and acquires the playing time of the video. Of course, the video to be displayed may also be pre-stored in the memory of the intelligent gateway and retrieved from the memory as needed.
And S20, dividing the 24 hours from 0 point to 24 points into a plurality of time periods by taking the time length of the video to be displayed as time granularity.
For example, if the duration of the video to be displayed is 305s, then, in one day, 0: 00: 00 to 24: 00: the number of time periods can be obtained by dividing the 24 hours in 00 hours by 305 s. The starting point of the division can be selected according to actual requirements, such as: with the duration of the video to be displayed as the time granularity, and the 0 point as the starting point, dividing 24 hours from the 0 point to the 24 points into a plurality of time periods, which may also be 03: 15: 00 is the starting point, and the division is carried out. If the division is performed by taking the point 0 as the starting point, the division result is as follows: the first time period: 0: 00: 00-0: 05: 05, carrying out a reaction; the second time period is as follows: 0: 05: 05-0: 10: 10; a third time period: 0: 10: 10-0: 15: 15 … …, and so on.
It is to be understood that the 24 hour period is divided by the time granularity, and when not divided, the last period of time may be less than the time granularity. Continuing with the above example, the nth time period is: 23: 58: 35-24: 00: 00.
in addition, the unit of the time granularity can be selected according to actual requirements, for example, the unit can be milliseconds ms, and can also be seconds s.
And S30, acquiring the starting time of each time period to obtain the playing time.
Continuing with the above example, the playing time is: 0: 00: 00. 0: 05: 05. 0: 10: 10 … …, 23: 58: 35.
and S40, synchronizing the local time to the network time.
And each intelligent gateway synchronizes the local time into the network time so as to ensure that the absolute time of all the intelligent gateways is synchronized uniformly. The time synchronization method can be selected according to actual requirements, and the application is not limited at all.
And S50, when the local time reaches the playing time, controlling the intelligent street lamp display screen to play the video to be displayed from the beginning.
And the intelligent gateway adds all the playing moments into a timer for timing. The timer program carries out monitoring once according to a period (can be one second), and when the fact that the local time reaches the playing time is detected, the intelligent street lamp display screen is controlled to play the video to be displayed from the beginning. Therefore, the local time of all the intelligent gateways is consistent, the played videos are the same, and the starting time points of the played videos are consistent, so that the synchronization of the played pictures of all the intelligent street lamp display screens can be ensured.
In this embodiment, the duration of the video to be displayed is used as the time granularity, 24 hours a day is divided, and the starting time of the divided time period is used as the playing time. On the basis of synchronizing the local time, the display screen is controlled to play the video at the playing time, and synchronous display of the pictures is realized. Like this, guarantee that every wisdom gateway's local time is unanimous, broadcast content and time length are unanimous, and the broadcast inception moment is unanimous, can guarantee all display screen picture synchronous broadcast, and synchronous effectual to increase substantially the city looks. In addition, the intelligent gateway and the display screen are in direct communication connection in the method provided by the embodiment, the connection quantity is small, the problem that interference of surrounding environment is easy to occur in the communication networking process of the LOAR module and the GPS module in the traditional technology is solved, and therefore the synchronization effect is good. In addition, the method provided by the embodiment realizes the picture synchronization of the display screen through the intelligent gateway, and the intelligent gateway is a standard component of each intelligent street lamp, so that compared with the prior art, no additional hardware facility is needed, the hardware cost is greatly saved, and the maintenance is also more convenient.

s410, judging whether the local time reaches the playing time or not;
if yes, go to S420;
if not, returning to execute the step S410;
s420, controlling the intelligent street lamp display screen to play the video to be displayed from the beginning;
with continued reference to fig. 3, in an embodiment, when the local time reaches the play time, before S420, the method further includes:
s60, determining whether a cancel playing command is received;
if yes, go to step S70;
if not, go to step S420;
and S70, controlling the intelligent street lamp display screen to quit playing.
With continued reference to fig. 3, in an embodiment, when the local time does not reach the play time, before returning to execute S410, the method further includes:
s60, determining whether a cancel playing command is received;
if yes, go to step S70;
if not, the process returns to step S410.
And the canceling play command is used for indicating the intelligent gateway to control the display screen to quit playing. The cancel play command can be sent to the intelligent gateway by the control platform. And when the intelligent gateway receives the command of canceling the playing, exiting the current playing. In the embodiment, whether the playing canceling command is received or not is determined, so that the playing quit in time when the playing canceling command is received, and the intelligence and the practicability of the method are improved.
In one embodiment, the synchronizing the local time to the network time S40 includes:
based on Network Time Protocol (NTP), local Time is synchronized to Network Time.
The intelligent gateway can be internally provided with an NTP client, and the intelligent gateway controls and starts the NTP client to carry out time synchronization, so that the local time is consistent with the time of the NTP server, and the local time of all the intelligent gateways is guaranteed to be consistent. The intelligent gateway realizes that the local time synchronization can be carried out at regular time or according to the period for the network time, namely, the time synchronization is carried out once at intervals of preset duration, so as to further improve the accuracy of the time synchronization.
