First, the concept:
3G asynchronous control system is a networked LED display content production, transmission, control system platform, through the 3G wireless network to connect the LED display to the Internet, users through PC, tablet PC, smart phone and other terminal equipment management platform For the management and maintenance of the LED display, a single LED display or a batch of multiple LED display management can be realized.
Second, the main components of the system:
Send box, receiving card, 3G module, LED sign management platform.
Third, how to use:
The user only needs to use the network terminal device to log in to the webpage management platform, and input the account password to control and manage the LED display screen. For example, the LED display information is released, updated, deleted, added, inserted, synchronized, and the like.
Fourth, the main application:
1, Â Â Outdoor LED display control, car LED display, high-speed road advertising LED display control, cluster management LED display control. At present, it mainly targets foreign trade, government agencies, institutions, transportation, advertising, and media.
Five, characteristics
1, 3G network transmission speed is faster than GPRS, 10-20 times that of GPRS. More suitable for streaming video content.
2, the management platform is based on the B / S structure, belongs to WEB web page management, so users can:
a, log in to the platform for management at any place , for example, users can also control Shanghai's LED display in Shenzhen.
b. The management platform has powerful terminal management functions, which enable real-time viewing of devices online and offline.
c, login management platform, you can remotely program, send, add, delete and other management.
d, remote time switch machine, remote insertion, remote monitoring screen play task.
3, the display can be divided into different groups or different customers, the content can be updated separately, can also be grouped, can play the same content, can also be different content.
4, through the timing and calibration, can achieve synchronous playback of the display content.
5 The best control scheme for outdoor LED display, no wiring, unlimited distance and fast transmission speed.
6, integrated design, low cost, simple operation.
7. The data center was established by Shenzhen Unisex, eliminating the need for customers to build and maintain servers.
8, easy maintenance and technical support to minimize system complexity.
9, for high-volume application customers, you can build your own server.
10, to solve the problem of communication restrictions between different operators, to achieve wireless connectivity.
11, rich information display: each information can be customized to its display mode and dwell time, can be arranged in any way, very flexible.
12, multiple language choices: such as numbers, letters, Chinese, English and so on.
13, a variety of information encryption methods: If you can set the information according to user needs to send information to add the identification code and check code, or only receive a dedicated number. Keep information safe.
14, easy to install and maintain: because there is no need to lay fiber optic cable or communication cable, the installation position of the wireless LED display is easy to choose. Modular design, easy to maintain and overhaul, and automatically save all information automatically dial-up Internet access, automatic redialing of dropped calls, ensuring reliable connection, wireless LED display automatically plays original information when power is turned off again after power off, anti-interference design, suitable for electromagnetic Harsh environment application, high and low temperature design, suitable for low temperature and high temperature working environment.
The advantage of the company's products and other companies is that we are WEB webpage management, do not need to download software, so it is more convenient for foreign trade customers.
Communication type | Communication distance | Display content | Accessories | Traffic cost |

GPRS | 2G signal is available, distance is not limited | Suitable for text, pictures | GPRS module | Depending on the local cost standard, the flow is generated |
WIFI | WIFI signal is available, distance is limited | Suitable for pictures, text, videos, weather, dates | WIFI module | No fee |
the Internet | Can access the Internet, the distance is limited | Suitable for pictures, text, video, weather, dates. | Wired connection and router | No fee |
Sixth, the system works:
1, Â Â Â Â Â Â Â Â Â After the control card, LED display, etc. are connected, it automatically connects to the 3G network data center and reports the serial number and affiliated users.
2, Â Â Â Â Â Â Â Â Â The data center manages all access control cards according to the user name; and monitors the online and offline status of the control card in real time.
3, Â Â Â Â Â Â Â Â Â After the user connects to the 3G network data center and logs in with his or her own username, the 3G network data center will naturally establish a mapping relationship with all the control cards of the user and control the user.
Six, the main product parameters:
1 control card parameters
3G one card (just one card, no need to receive cards, etc.)
3G cascade control card
receive card
