The design of the wireless LED information release system implementation

Overview:

the traditional LED display by directly connected to the computer to change the display information, unable to realize the remote real-time update of the screen information, also can't build a networked information release system.

the wireless LED information release system adopts a kind of brand-new updated information screen, based on the GPRS/CDMA wireless network technology, provides a common RS - 232 interface, mobile data transmission platform of LED display and multimedia information publishing system, in a fixed place, mobile facilities installed in the wireless LED electronic display terminal, realize the network control of the LED display. Either a regular text of the screen, or the big screen by screen, can be covered by wireless information terminal, realize remote real-time update of the information. Regardless of their number, where LED display, the system of the main control center can be accurate, instant release the information to the specified one or more of the screen. The wireless LED information release system greatly enhance the flexibility of LED display as information display carrier release information and real-time performance, work to expand its application.

2, application scope,

as a new information carrier, the wireless LED information release system has a broad market and USES, and can be widely used in government, business, transportation, catering, construction, transportation, travel, sports and other industries and sectors.

LED display screen can also be used for tourist attractions, the group enterprise, the unit interior independent wireless networking, so as to realize multi-stage, across, flat Shared wireless information release system.

3, system structure ZWINFO remote information release system includes three parts: center control computer, wireless communication terminals and LED display. System schematic diagram is shown in figure 1.

figure 1, the golden color for Shanghai is wei digital technology co. , LTD ZWINFO products information release system.

screen set to publish the information of various remote locations, each display configuration a information terminals, information released through SM or GPRS terminal and center computer communication. Using GPRS mode, the terminal connected to the INTERNET the INTERNET through GPRS mode, at the same time, the computer is used to release information through the special line, ISDN, ADSL, dial a number of ways, such as connected to the INTERNET, network communication through the INTERNET connection, the center of the computer can be in the form of TCP/IP and the display screen for centralized data transmission and release, whether screen placed in the same city, the same area, can be cheap concentrated in the center of the management of information release, to achieve reunification of the information management and maintenance.

system can be many different areas or display real-time information release. Four, the function and characteristics:

in addition to the power supply without any wiring, save material and construction cost

is not restricted by time and region, climate, the screen can be placed anywhere in the

management center remote information update, without any site operation

can change the screen parameters and remote update screen information

update speed, information can be modified at any time, obvious advantages compared with the scene change

updates can be unified in full screen operation, also can be operated for any one or more

operation cost is low, compared with the artificial modification of information, no later use cost information published

release software can save and publish information, convenient query, is advantageous for the system to safeguard the unity of the

all screen management, maintenance, improve the efficiency of maintenance, lower maintenance cost

the whole system more controllable, reliable, give full play to the efficiency and superiority of system

by modifying the software to provide other required functionality

5, equipment technical parameters of the

ZWINFO remote information release the appearance of terminal diagram is shown in figure 3.

remote information release terminal interface and parameter is as follows:

power supply interface: dc 5 - 16V;

SIM card interface, 3 vsim card;

the antenna interface;

LED interface, female DB9 interface;

control input/output interface, RJ45 interface;

MICPHONE interface;

power consumption: 0. 1 - 2 w。 Asynchronous graphic control card parameters are as follows:

scope of monochrome/double colors

scan space than 1/4

maximum control point 124 k ( K=1024) Max point 1280

transverse longitudinal maximum 96

the storage capacity of the standard 512 KB ( Most customizable 1 MB)

the clock display is

string moving clock support only 16 points a CK

11 MHZ clock frequency, 5. 5米,3。 7米,2。 8 m >

the field scanning frequency 90 hz power supply power supply 5 v

6, software instructions

ZWINFO remote information release system is the center of the management software and monitoring terminal docking for information release, terminal control, terminal management, information management server software.

center management software running in the monitoring center server, the computer is connected to the Internet in many ways, the terminal of receiving information through the Internet and TCP connection to the server, or to directly communicate via the GSM SM, then is wei digital ZWMODEM - may be used SM wireless message sending and receiving terminal.

center management software mainly complete the management of multiple display screen, control functions, to display the data stored for editing. At the same time, through the software can be for all terminals for remote control and remote data acquisition.

center management software also complete the storage and management of information, terminal management, information update regularly, and other functions. Information release point can be set to release timing.

in the center of the same software, can to control the state of information release and multiple terminals.

center software interface as shown in figure 4.
