The principle of LED adapter generation: In this system, the generation of LED adapter uses a very key technology JNI, JNI is the abbreviation of Java Native Interface (Java local interface). The so-called local interface is relative to the Java program running in the "sandbox" of the Java virtual machine. It refers to the program that runs directly on the operating system and directly interacts with the operating system. It allows Java programs and programs written in other languages to program to interact. JNI was originally designed for the interoperability of Java programs and native compiled languages, especially C and C++, but this does not mean that other languages cannot be used. It is diverse for our underlying LED drivers. Need to adapt to various application platforms. JNI can be visually and intuitively regarded as the glue between Java and local applications. The JNI specification becomes an intermediary between C language class libraries and functions and Java objects.

With the glue of JNI, we can solve the problem of communication protocol conversion of Kua platform very well.

A plurality of LED driver modules 26 are connected to the LED adapter and the LED screen (for example, arranged between the LED adapter and the LED screen) for sending display data to the corresponding LED control card.

LED driver chip optimization algorithm: makes the application circuit very simple, and few peripheral parts are needed, which is in line with the concept of low cost and industrial production. The following figure is a typical application circuit. After adopting the primary side constant current technology, the secondary feedback circuit is no longer an obstacle in terms of power supply size and cost, which brings great convenience to occasions where the power supply volume is extremely demanding. The traditional optocoupler feedback structure still has the problems of optocoupler aging and safety testing. For the application environment temperature of 60-90℃ inside the bulb lamp, the reliability problem has become the focus of attention of manufacturers and customers. The maturity of constant current technology on the primary side, especially the new technology of innovative driver chip algorithm design, makes the application circuit insensitive to some difficult-to-quality-control parameters of transformers and inductors. For LED lighting power supply and lamp manufacturers It is a win-win choice that can not only improve product performance conveniently, but also reduce costs. There are fewer parts and devices around the circuit, but power circuit designers should choose high-quality devices for limited devices, such as MOS with high withstand voltage, and electrolytic capacitors with high sealing performance, high anti-hydration ability, and high anti-overload ability. 125°C 10,000-hour long-life product to adapt to long-term work in high-temperature environments.

-LED data processing step, refreshes LED and shows view, in real time control LED element layout, the reading of control card data and element data, renewal management work;

-LED screen template simulative display step, the LED screen interface of simulation, according to design data information, performance final design effect strictly according to the facts;

Described backstage display and control flow process comprises:

-parameterized template setting procedure, definition LED data source style of loading, makes it have being loaded by LED control card of format;

-LED screen template sets step, the pattern of definition light-emitting diode display display, and the parameter corresponding to often kind of display object;

-LED control card management process, the size parameter of definition LED control card, and hardware management communication mode, mailing address data message are LED adapter service;

The parameter information that-LED adapter provides according to LED control card and activation bit define the adapter of this control card, by JNI technology, LED data are converted to the logical information protocol that LED control card identifies and send to LED screen;

-some LED drive module send display data to corresponding LED control card.

7. the method for designing of LED Display designing system according to claim 6, is characterized in that:

The software interface of described system is divided into 6 regions, comprising:

First area, as LED parameterized template tree viewing area, is used for loading and shows available template field information;

Second area, as LED control card structure tree viewing area, is used for display control card and the element information that comprises thereof;

3rd region, as toolbar button region, places corresponding function button;

4th region, as main perform region, supports the display container of multiple Tab design drawing plate;

5th region, as information region, prompting message may be displayed on this part;

6th region, as object properties region, is used for display, editor control card or LED attribute of an element project.

8. the method for designing of LED Display designing system according to claim 6, is characterized in that:

The flow process of described parameterized template management process comprises:

Step S111, parsing LED parameterized template XML, the parameter class data set in traversal template and detailed class data set;

Step S112, parameter data set and detailed data collection are carried out JAVA object instantiation, stored in the JAVA object of correspondence;

Step S113, in Action by parameter JAVA object good for instantiation, translate into string by JSON object parser, then character string returned user requests webpage;

In JavaScript script in step S114, JSP, by the character string parsing tool method in ExtJS, the character information received is translated into the discernible JSON object information of JS from Action;

Step S115, JSON object information are packaged into can for the tree-shaped node of user operation.

9. the method for designing of LED Display designing system according to claim 6, is characterized in that:

The implementation procedure of described LED data processing step is as follows:

First from database, read out the data message of control card, LED element, convert it into corresponding JAVA and JSON object; In front page layout, first corresponding according to the quantity initialization of control card perform region panel Panel, is registered in the middle of global view by the panel object that instantiation is good, for other function quick calling later;

Then in the panel generated, a canvas object Canvas is increased, the attribute information of this object is according to control card data community, one_to_one corresponding and come, then, in control card structure tree, a newly-increased leaf nodes, sets up corresponding relation by the click event of this node and panel, painting canvas, and control card is carried out location registration process;

The all LED element datas of the current control card of last searching loop, according to the difference of element type, call corresponding object drawing practice respectively, control its display position, style content, simultaneously in LED structure tree, increase leaf nodes;

If the LED element of not drawing, then complete the loading procedure of a control card.
