Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

3-dimensional digital water curtain control method of the present invention, based on 3-dimensional digital water curtain control system, as shown in Figure 1, 3-dimensional digital water curtain Control system architecture is: comprise the lower header 1 and upper water box 4 that are connected by water pipe 3, above lower header 1, splash proof network is installed, prevent the water column fallen from upper water box 4 from spattering to surrounding is loose, water pump 2 is provided with in lower header 1, above water pump 2 water inlet and upper water box 4, screen pack is installed, impurity is prevented to be mixed in water, electromagnetic water valve 5 is provided with in upper water box 4, the vertical height of electromagnetic water valve 5 is 3 ~ 12m, upper water box 4 side is vertically provided with two sensors 6, two sensors 6 obtain upper water box 4 water level information, two sensors 6 are all connected with water pump 2, when upper water box 4 water level is started working lower than water pump during lower face sensor 62, and quit work higher than water pump during upper face sensor 62, electromagnetic water valve 5 presses the arrangement of level matrix form, upper water box 4 is connection control system 7 also, control system 7 comprises single-chip microcomputer 8, single-chip microcomputer 8 model is Arduino Mega 2560, single-chip microcomputer 8 control and drive system 9 drives the Switching Power Supply 10 of each electromagnetic water valve 5, driver 9 is L298N module, single-chip microcomputer 8 controls the switching frequency of electromagnetic water valve 5,

Specifically implement according to following steps:

Step 1, first determine that electromagnetic water valve 5 sprays the word or pattern that water column will show, y1 is defined as successively by horizontally-arranged for electromagnetic water valve 5, y2, y3 ... yi, electromagnetic water valve 5 tandem is defined as x1 successively, x2, x3 ... xi, delivery from the bottom of the word that electromagnetic water valve 5 will show or pattern, needs the part lighted to represent with 1,1 expression high level, the part lighted is not needed to represent with 0,0 represents low level, if the display of neighbouring two row or multirow is identical, can merge into one group of delivery;

Step 2, according to step 1 want word or the pattern-information of delivery, the digital I/O mouth { 6 of definition single-chip microcomputer 8, 8, 10, 2i, 2i+4} is one-dimension array pinx [i], its control and drive system 9 signal input, the signal output of driver 9 meets the x1 of electromagnetic water valve, x2, x3 ... the i root line of xi, the digital I/O mouth { 5 of definition single-chip microcomputer 8, 7, 9, 2i+1, 2i+3} is another one-dimension array piny [i], the signal input of its control and drive system 9, the signal output of driver 9 meets the y1 of electromagnetic water valve, y2, y3 ... the i root line of yi,

Step 3, mould step 2 obtained give one-dimension array HLxi [i] and HLyi [i];

Step 4, use repeatedly circulation perform the one-dimension array HLyi [i] and HLxi [i] that obtain in step 3, often perform one-dimension array HLyi [i], perform all HLxi [i] once.

Electromagnetic water valve in digital water curtain selects the electromagnetic water valve of ultra-high frequency, low pressure, life-span length, the horizontal spacing of electromagnetic water valve should be equal with longitudinal pitch, and support can be built by various material, and its bottom puts down water tank, upper strata supports upper water box and electromagnetic water valve, is furnished with light above support with surrounding.

Choosing of water pump will be noted: water lift of pump is greater than the overall clear height of this device, the flow losses of pipeline will be considered during selection, the flow of its unit interval is larger than the specific discharge sum of all electromagnetic water valves, the water level of upper water box should keep certain height, to ensure that the pressure of electromagnetic water valve water delivering orifice is substantially for definite value.

In control system, single-chip microcomputer is Arduino Mega 2560, and single-chip microcomputer is that 5V-9V powers, a kind of AVR single chip, it has 54 digital I/O mouths, in-chip FLASH capacity 256KB, work clock 16MHz, SRAM is 8K, EEPROM is 4K, and later stage single-chip microcomputer will be replaced by ARMSTM32f103zet6, and driver is L298N module, one piece of exportable 4 road low and high level of L298N, and the low and high level exported between L298N also can drive electromagnetic water valve.

Music lamp photosystem in 3-dimensional digital water curtain is made up of stereo set and light units, music can increase the regular movements sense of digital water curtain, light can increase the picture sense of digital water curtain, light should be arranged in flowing water and fall to showing optimal position, with the best effects highlighted, water pump, light are 12V and power, and all use its switch of Control, also arrange hand switch, musical portions is responsible for by player, sound equipment.

When making large-scale three dimensional digital water curtain (total thousands of electromagnetic water valves), according to the method described above, its scanning time used is elongated, affect the precision of 3-dimensional digital water curtain, such as 3-dimensional digital water curtain totally 4096 electromagnetic water valves, when it arranges arrangement according to six Ariadnes 64, its mode of connection is not with the mode of connection that six above-mentioned Ariadnes 64 arrange, and make into 512 row eight arrange the mode of connection (electromagnetic water valve still with six Ariadnes 64 arrange arrangement, just its mode of connection changes), its principle does not change, if single-chip microcomputer does not have enough digital I/O mouths, then need to increase latch to expand its I/O mouth.

Distance between multiple electromagnetic water valves of digital water curtain cross direction profiles forms the level picture number of word or pattern, the time of electromagnetic water valve break-make forms the vertical picture number of word or pattern, in order to show word or the pattern of a suitable size, wherein, the vertical height of electromagnetic water valve and electromagnetic water valve total length are positively related relations, electromagnetic water valve is vertically highly higher, electromagnetic water valve total length should be longer, vertical height should at 3 ~ 12 meters, thus, delay time in program between circulation is after simple computation, verify the optimum delay time in an experiment, delay time is not a definite value, delay time is above short, delay time below increases gradually.

Institute's invention 3-dimensional digital water curtain control method, digital water curtain is made more to have wide market application foreground, stronger display effect and impact, can be applicable to the multiple uses such as amusement, advertisement, displaying, can be applicable to the places such as science and technology center, exhibition center, market, also can with building perfect adaptation, form a kind of new architectural design, all right environment purification, produces a large amount of negative ion, regulate humidity, purify air.
