Problems solved by technology

like figure 1 As shown, the conventional LED display control system needs to install a graphics card 02 and a sending card 03 on the control host 01, and the DVI interface, audio interface, and USB interface of the graphics card 02 need to be output to the sending card 03, and the sending card 03 passes through Gigabit The network layer transmits the data to the receiving card 04, and then outputs it to the LED display 05 through the receiving card 04. During installation and debugging, it is necessary to install a graphics card driver, USB driver, etc. on the control host 01. The operation steps are cumbersome and cannot meet the requirements of the LED display. Market demand, and need to bear the cost of sending card and graphics card

Abstract

The invention discloses a transmitting-card-free low-cost light emitting diode (LED) synchronous display controlling system. The transmitting-card-free low-cost LED synchronous display control system comprises a controlling mainframe, an LED receiving card array, and an LED display screen. The mainframe is connected with the LED receiving card array through a network. The LED receiving card array is connected with the LED display screen. The LED receiving card array comprises more than one LED receiving card monomer, wherein LED receiving card monomers are connected in series. The LED receiving card monomers are provided with more than one network access module used for transmitting data, a field programmable gata array module (FPGA), a monitoring sensor, an audio output connector, a nonvolatile memory used for storing system parameters, a synchronous dynamic random access memory, an LED scanning driver interface, and a PFGA connecting module. The network access modules, the monitoring sensor, the nonvolatile memory, the audio output connector and the synchronous dynamic random access memory are connected with the LED scanning driver interface and the PFGA connecting module. The transmitting-card-free low-cost LED synchronous display control system can reduce a transmitting card needed by a normal LED synchronous display control system and avoid a series of installing steps of a computer video card and a transmitting card.

Description

technical field [0001] The invention relates to an LED synchronous display control system, in particular to an LED synchronous display control system without a sending card. Background technique [0002] With the rapid development of LED display screens, the requirements for LED display control systems are getting higher and higher, and the cost requirements are getting lower and lower. Such as figure 1 As shown, the conventional LED display control system needs to install a graphics card 02 and a sending card 03 on the control host 01, and the DVI interface, audio interface, and USB interface of the graphics card 02 need to be output to the sending card 03, and the sending card 03 passes through Gigabit The network layer transmits the data to the receiving card 04, and then outputs it to the LED display 05 through the receiving card 04. During installation and debugging, it is necessary to install a graphics card driver, USB driver, etc. on the control host 01. The operati...
