Synchronous play method based on LED text advertisements

Abstract

The invention discloses a synchronous play method based on LED text advertisements, comprising the following steps: a computer processing system of a vehicle-mounted terminal operates an LED screen timing program in regular time, the LED screen automatically realizes timing, so that the LED screen and the vehicle-mounted terminal share synchronous system time, each time of LCD screen timing is correct to second, the timing result error is confined to an error range of several milliseconds, so the timing accuracy is very high; as a result, the requirement that the LEC screen and the vehicle-mounted play advertisements synchronously is completely realized; in the process of LED screen timing, each time of the implementation of the timing program sees three times of continuous timing, thus ensuring timing effect, improving system fault-tolerant capacity and ensuring normal operation of the system; the vehicle-mounted terminal transmits a programme to a far-end server every half an hour and carries out LED screen timing; or when the programme of the far-end server is updated, the far-end server automatically issues advertisements to the vehicle-mounted terminal, so that the vehicle-mounted terminal can obtain new advertisements entered by the far-end server in time and plays the advertisements according to flight information on time.

Description

technical field [0001] The invention relates to a method for synchronously playing LED text advertisements, in particular to a method for realizing synchronously playing on LED screens with a control flow. Background technique [0002] LED screen is a new type of imaging electronic equipment made of light-emitting diodes arranged in sequence. As a new display medium, LED screen has developed rapidly with the rapid development of large-scale integrated circuits and computer technology. Compared with traditional display media, it is widely used in all walks of life due to its advantages of high brightness, good dynamic image display effect, low failure, low energy consumption, long service life, various display contents, rich display methods, and high performance-price ratio. industry, such as in the automotive field. As more and more LED screens are used as vehicle-mounted display devices in the vehicle-mounted field, using vehicle-mounted LED screens to publish text informa...

AI Technical Summary

Problems solved by technology

As more and more LED screens are used as vehicle-mounted display devices in the vehicle-mounted field, using vehicle-mounted LED screens to publish text information advertisements has become another position for advertising operators to carry out advertising business. The time requirement must be synchronized. The time synchronization between the car LED screen and the car station (i.e. car terminal) means that the time of the LED screen and the time of the car station are only a millisecond difference, and they should be exactly the same in seconds. Only in this way can the text advertisement be accurate to Seconds on time to achieve system requirements, however, because the time of the existing vehicle-mounted terminal and vehicle-mounted LED screen is not completely synchronized, it affects the synchronous playback of text advertisements on the LED screen
