Each electromagnetic water valve 6 is all in series with diode 7, the effect of series diode is to make electromagnetic water valve unilateal conduction, this mode of connection can be energized and open any one electromagnetic water valve, an electromagnetic water valve is ranked second for a line 16 to open, then need to y1 low level, x2 high level, other xi low levels, y1 and x1, x2, x16 totally 17 lines are connected on plug-in type connection terminal, the connection terminal other end connects line, for being connected with control system, is convenient to like this be separated electromagnetic water valve and control system, be conducive to safeguarding, dismounting.
For Arduino Mega 2560 single-chip microcomputer, circuit design is described, the scheme of programming and control: single-chip microcomputer is that 5V-9V powers, definition single-chip microcomputer digital I/O port { 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52} is one-dimension array pinx [16], it controls totally 16 signal inputs of four driver L298N, totally 16 signal outputs of four driver L298N meet the x1 of electromagnetic water valve, x2, x3 ... x15, 16 lines of x16, define digital I/O mouth { 23, 25, 27, 29} is another one-dimension array piny [4], it controls totally 4 signal inputs of a driver L298N, totally 4 signal outputs of driver L298N meet the y1 of electromagnetic water valve one by one, y2, y3, 4 lines of y4, wherein only use y1 single line, for y1 is connect low level, electromagnetic water valve voltage is 24V, therefore the power supply terminal of L298N connects 24V power supply, output port voltage is made to be 24V or 0V.
Electromagnetic water valve in digital water curtain selects the electromagnetic water valve of ultra-high frequency, low pressure, life-span length, the circuit of electromagnetic water valve and the use of driver significantly can be reduced for it designs mode of connection, complexity, the difficulty of programming reduce, thus reduce cost, support can be built by various material, its bottom puts down water tank, and 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, will consider the flow losses of pipeline during selection, and 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, separately on rear side of upper water box, establish about two sensors in a distance, obtain upper water box water level information, when upper water box water level is started working lower than water pump during lower sensor, and quit work higher than water pump during upper sensor, above water pump water inlet and upper water box, screen pack is installed, prevent impurity to be mixed in water, at lower header, splash proof network is installed, prevent overboard faling apart from spattering.
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 ARM STM32f103zet6, 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.
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.
The control method of this digital water curtain wiring system invented reduces the cost of digital water curtain, 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.
The control method of digital water curtain wiring system of the present invention can also be simplified, arrange for a line 16, as Fig. 4, for drawing conveniently, electromagnetic water valve one four lines four is arranged placement, reality is that a line 16 arranges placement, electromagnetic water valve mode of connection is, in figure, the single line of each electromagnetic water valve of each row of electromagnetic water valve is connected a diode, model is 1N4001, then be connected in parallel, draw four with line, be defined as y1, y2, y3, y4, often the single line of each electromagnetic water valve of row electromagnetic water valve is connected in parallel extraction four with line, be defined as x1, x2, x3, x4.
For Arduino Mega 2560 single-chip microcomputer, circuit design is described, the scheme of programming and control: single-chip microcomputer is that 5V-9V powers, definition single-chip microcomputer numeral I/O mouth { 22, 24, 26, 28} is one-dimension array pinx [4], it controls 4 signal inputs of a driver L298N, 4 signal outputs of a driver L298N meet the x1 of electromagnetic water valve, x2, x3, 4 lines of x14, define digital I/O mouth { 23, 25, 27, 29, be another one-dimension array piny [16], it controls 4 signal inputs of a driver L298N, 4 signal outputs of a driver L298N meet the y1 of electromagnetic water valve, y2, y3, 4 lines of y4, electromagnetic water valve voltage is 24V, therefore the power supply terminal of L298N connects 24V power supply, output port voltage is made to be 24V or 0V, in order to the matrix ranking method of the electromagnetic water valve with design combines, devise this program, first word to display is determined, pattern, for " west " word, delivery bottom it, the part lighted is needed to represent with 1, 1 represents 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, one group of delivery can be merged into, last delivery result is:
