The wireless LED display operating mode and its characteristics -- LED display - knowledge

LED display is a high-tech display, its function is strong. Remote operation technology, it is not restricted by geography, distance, cabling, etc. So, how to operate the wireless LED display some of the ways and some of its characteristics is the following as an introduction to the wireless full-color LED display: full color LED display: the characteristics of wireless network scale: wireless LED display through GSM, GPRS, CDMA, 3 g wireless network to send information, such as by using TCP/IP network transport protocol, terminal connected to the Internet there is no limit on the number, can therefore large-scale network. Second, real-time release information: wireless LED display can receive information center issued by the ministry of information. Three, without being limited by the distance: wireless LED display can be used across the country, as long as there is you can use the wireless network signal coverage, not restricted by distance and location. Four, easy installation and maintenance: because do not need laying optical cable or communication cable, the installation position of the wireless LED display is easy to choose. Modular design, easy to maintain and repair, and automatically save all information automatic dial-up, drops automatic redial, ensure reliable connection, the wireless LED display when energized again when the power is automatically play the original information, anti-interference design, electromagnetic environment is suitable for application of high and low temperature design, adapt to the low and high temperature working environment. Five, a variety of ways to disseminate information: according to the selected network is different, you can choose different way to send information to update the wireless LED screen information, and can be mass, group, single point send information. Sent via Internet related websites, such as: computer, computer through a dedicated information delivery module to send, ordinary mobile phone to send, etc. Sixth, a variety of LED display options: all kinds of indoor, outdoor, outdoor single color, double colors, color, etc. Seven, choice of multiple languages, such as Numbers, letters, Chinese, English, etc. Eight, a wealth of information display mode: each information can customize it display mode and the residence time, can be arbitrary format, according to a very flexible. Nine, a variety of information encryption method: according to user needs, such as setting information is sent to join the identification number and the check code, or only receive special number. Ensure information security. Function, support a variety of special effects. Full-color LED display, wireless control way: a, RF wireless control working principle: the RF module end receives control computer, on the other side received serial port control card, computer after install driver, to create a virtual serial port, and through the serial port to send data. Second, the WIFI control working principle: by adding wireless router or other wireless devices, and original bridge wireless network, users build a wireless local area network (LAN), convenient control the network card into the wireless network, wireless network control. Three, GPRS wireless control works: GPRS module to add electricity after completed the course of dial-up Internet access, connect to the data center server, client access server through client software, by the server to forward information. Four, 3 g ( WCDMA) Wireless control works: 3 g module is through the wireless network connection to the data center server, client landing directly release programs broadcast cloud platform in the world, sent to the control card directly by the server.
