Apparatus for collecting display parameter of LED display screen based on wireless digital transmission communication

Abstract

The invention relates to a device for acquiring display parameters of an LED display screen based on wireless data transmission communication, wherein an acquisition computer of the device is connected with a display parameter acquisition device through an acquisition data wire; a display control computer is connected with the LED display screen through a data transmission line of the display screen; and the acquisition computer, a first wireless data transmission communication station, a second wireless data transmission communication station and the display control computer form a wireless data transmission communication station communication network. The acquisition computer and the display control computer do not need wired connection, so that the device does not need secondary field wiring, is not influenced by field road surface barriers and so on, reduces the requirement of the device on a field environment, shortens the first-phase preparation time for acquiring the display parameters of the LED display screen, improves the work efficiency and the practicability of the display parameter acquisition device of the LED display screen, and can quickly and conveniently realize acquisition of the display parameters of the LED display screen.

Description

technical field [0001] The invention relates to a display parameter collection device of an LED display screen, in particular to a display parameter collection device of an LED display screen based on wireless data transmission communication. Background technique [0002] The existing LED display display parameter acquisition device includes display parameter acquisition equipment and a main control computer. The display parameter acquisition device is located in front of the LED display. The main control computer controls the display parameter acquisition device through the acquisition data line to collect the data of the display parameters, and sends display information to the LED display through the display data transmission line. [0003] The outdoor LED display screen is usually installed on the building facing the street, and the bustling market is under the screen body. The display parameter acquisition equipment and the LED display may be separated by road surface ...

AI Technical Summary

Problems solved by technology

The display parameter acquisition equipment and the LED display may be separated by road surface obstacles such as non-motorized lanes, motorized lanes, and road fences. The data transmission line of the display screen crosses the street, which is easily damaged by motor vehicles and pedestrians. In some cases, the actual wiring distance between the main control computer and the LED display screen will exceed the effective transmission distance of the display data transmission line, and the on-site wiring is difficult to meet Acquisition requirements for LED display display parameters

Moreover, the on-site main control computer is usually installed in the near end of the LED display screen or in the remote control room. If the display parameters are collected, the main control computer needs to be moved to the collection site, which increases the preparation time for the collection and is very inconvenient for the collection work.
