Principle of LED display wireless control!

Now the main control method of LED display basically adopts wireless control method. There are five wireless control methods for LED display screens. Below, Shenzhen Liansen describes the principles of these five wireless control methods!



One, RF wireless control



Working principle: One end of the RF module is connected to the control computer, and the other end is connected to the serial port of the control card. After the computer installs the driver, a virtual serial port is generated and data is sent through this serial port.



Two, WIFI wireless control



Working principle: By installing a wireless router or other wireless devices, bridge the user's original wireless network to build a wireless local area network, and easily integrate the network control card into the wireless network for wireless network control.



Three, GPRS wireless control



Working principle: After the GPRS module is powered on, it completes the process of dial-up Internet access and connects to the data center server. The client accesses the server through the client software, and the server forwards the information.



Four, 3G (WCDMA) wireless control



Working principle: The 3G module is also connected to the data center server through a wireless network, and the customer directly logs in to the Global Unicast cloud platform to publish the program, and the server sends the program directly to the control card.



Five, 4G full Netcom wireless control



Working principle: Basically the same as 3G/GPRS.
