Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
The utility model comprises master system, the control system, and drive system and backlight four parts, package unit adopts the alternating current of input voltage 220V, the direct current of output voltage 24V, rated voltage 24V, rated current 2A, actual required maximum current is 1.9A.
Backlight mainly by 4 independently backlight form; The every long 45cm of backlight independently, wide 33cm closely rearranges by 32 backlight; The outside is formed by white acrylic board encapsulation; Leave the edge that punches about 5cm above, available hook is hung on the fish jar wall with backlight, can adapt to experiment under water.Said backlight plate face is processed by the reflective membrane at the LCD back side, and the backlight side is processed by another kind of light screening material.Every backlight long 40cm, wide 1cm, an end is used the electric wire connection control system, and the other end is a blind end.Every backlight inside red-green-blue LED lamp that evenly distributes can be lighted simultaneously, and continuing to light the time minimum of a value is 20ms.
Master system mainly is divided into two zones, viewing area and experimental implementation zone.The readable real-time experiment parameter in viewing area comprises current experiment model, red, green and blue control ratio, the bright speed of light source and frequency etc.The experimental implementation zone comprises experiment model for self-defined each the required parameter value of experiment that is provided with, red, green and blue control ratio, and the bright speed of light source etc., and can preserve.
The control system connects master system and drive system, mainly is made up of a control circuit board.Control panel is the experiment parameter through obtaining laboratory technician input and send command adapted thereto, data to drive plate mainly; Show current experiment parameter, comprise color, frequency, brightness, experiment model etc.The serial communication program is obtained the drive plate current information, is sent director data to drive plate, and obtains host computer instruction and data.Control panel can be selected several kinds of built-in test models, adjusted colors, brightness on these experiment models basis, backlight width, these parameters of frequency.Host computer can independently define experiment model by the experimenter as required, directly controls each regional experiment parameter.
The control panel program flow diagram is seen Fig. 2.Detailed process is following:
System's first initialization that powers on comprises global variable and interrupt system.Program gets into endless loop then, carries out two tasks: show current experiment parameter and read data in the serial ports buffer memory, obtain drive plate information and host computer data.(the buffer memory simulation is here come out to read buffer memory; Because 89S51 microcontroller serial port buffer memory is very little; So buffer memory of simulation all dumps to the data in the serial ports in the middle of the internal memory, carries out sign; The program that common mode is intended buffer memory reads) in information, distinguish concrete instruction and data according to sign.
When actuation of keys, can produce external interrupt, and then get into the key scan program.Change experiment parameter according to experimenter's concrete operations.
When serial ports interrupted taking place, the interrupt response program directly was put into simulated cache with received data, and changed the sign of simulated cache according to data type.The purpose of doing like this is in order not lose serial data, to respond experimenter's operation fast.
Drive system connection control system and backlight, mainly by 4 independently circuit board constitute, each piece circuit board one end is communicated with control system, the other end is communicated with an independently backlight.
Driver mainly divides initialization, PWM control and serial data to receive three parts.Initialization comprises system initialization and experiment parameter initialization.System initialization comprises interruption, system variable is set, and realizes that drive plate and control panel are synchronous; The experiment parameter initialization is provided with the preset experiment parameter.The PWM control program is an endless loop, and program is preserved the dutycycle data of red-green-blue, according to this data values output pwm signal, regulates the brightness of every kind of color.System is through serial communication, and control panel all is through serial ports to driving the transmission director data.It is unit with two bytes that control panel sends program, and first byte is instruction, and second byte is data.Drive plate receives serial data and analyzes, and RGB dutycycle data are set, and can send current state to control panel by the control panel requirement.The drive controlling program flow diagram is seen Fig. 3.Drive circuit designs according to the lighting mode of forming the red-green-blue LED lamp that is furnished with among every backlight of every independent backlight.Every backlight drive circuit is seen Fig. 4.RED, GREEN, BLUE are respectively the driving signals of three kinds of colors of RGB; SELECT is single backlight and selects signal.Through regulating the PWM duty cycle adjustment RGB intensity of light source of RED, GREEN, BLUE driving signal, realize that color and light intensity change; Can specify every backlight light on and off situation and light source scintillation frequency through regulating the SELECT signal.
The drive plate detail flowchart is referring to Fig. 3, in detail as follows:
After system powered on, first initialization comprised global variable and interrupt system.Program gets into endless loop then, drives the backlight circuit.At a driver in the cycle; Program is provided with the pattern terminal signals earlier, also promptly exports the light on and off of every backlight of signal controlling, and RED, GREEN, BLUE terminal are put height; Read PWD global variable value then; Judge whether consistently with RED, GREEN, BLUE value, when consistent with RED, the RED terminal is put low; If when consistent with GREEN, the GREEN terminal is put low; If when consistent with the BLUE terminal, the BLUE terminal is put low.So endless loop.
When serial ports interrupts taking place, handle function and can at first judge first byte data that receives,, then abandon these data if inconsistent with the sequence number of byte; If consistent, then further accept instruction, further handle according to command content.As, if being red data, instruction receives instruction, then program can receive next byte data, and the RED value is set is these data.Other detailed instructions types are referring to Fig. 3.
Fig. 4 is the LED crossing current driver of every drive plate, and SELECT, RED, BLUE, GREEN are control signals, are given by drive plate.SELECT is a mode control signal, controls the light on and off situation of current plank; RED, GREEN, BLUE are the color control signals.Through the logical AND gate circuit these two kinds of signals are affacted the control terminal of drive circuit, can change the switch and the size of current of drive circuit, and then light on and off and the brightness of control LED.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
