Each output module on the master controller H1 is drawn an output interface P3; Connect one or behind the interface P3, have on the line and the corresponding interface P2 of system's required sub-controller EX quantity by the many lines that couple together.The input interface P1 of sub-controller docks one by one with P2, thereby makes master controller H1 and each sub-controller EX constitute an organic whole.
Need the tree lamp TL of control to be connected on the output module of sub-controller EX, tree lamp TL comprises the LED of 3 groups of different colours, is respectively red R, green G, blue B.Master controller comprises power module, central processing module, and the memory storage module, human-computer interaction module and two output modules, the vacant not usefulness of one of them output module, another is with five sub-controller EX.Sub-controller comprises input module, output module, and central processing module, memory storage module and 3 LED driver modules, each LED driver module drive one group of LED lamp on the tree lamp.Its connected mode shown in J2, in 4 lines, common port that line is three groups of LED wherein, its directly in succession anodal S of power supply.Other three lines are control line, are connecting the other end of three groups of LED respectively, and an other end of these three lines is connecting the driver module of sub-controller EX.
LED driver module is equivalent to the switch of route central processing module control, its circuit as shown in figure 11, wherein LED1 represents to set a lamp group on the lamp.When the P0.1 place is high level, the Q301 conducting, LED1 is equivalent to be connected on two poles S0, and between the S, at this moment LED1 is in illuminating state, extinguishes state otherwise be in.According to PWM (pulse width modulation mode) principle, can regulate the brightness of associated lamp group by regulating duty ratio, by adjusting to three primary colors (R, G, B) lamp group, the variable 16777216 kinds of colors that swap out under 8 PWM.
The power module of master controller H1 and sub-controller EX provides required DC5V voltage for controller, and it generally is made of rectification, filtering, voltage stabilizing three parts, as Figure 10.When system can just can realize with a typical application circuit of being made up of 78M05 (three terminal regulator), as Fig. 7 without rectifying part during by low-voltage DC supply.
The memory storage module can be made of AT24C02, but then can external serial EEPROM chip if contained EEPROM in the central processing element.
Central processing module is by 51 single-chip microcomputers and necessary peripheral circuit such as crystal oscillating circuit thereof, and electrify restoration circuit constitutes.
The output module of master controller adopts open collector output commonly used.As Fig. 8, it be three tunnel outputs of whole module (D1, D2, the D3) schematic diagram of a road (D1) wherein, all the other two-way are identical therewith.Wherein P0.1 connects an output pin of central processing element, and R602 is a pull-up resistor.
The output module of sub-controller similar with master control on circuit structure, but it has only one tunnel, i.e. D3.
The human-computer interaction module of master controller often comprises two parts, and the first is that autocoding is provided with number of repetition (can be understood as sub-controller quantity), and it mainly is made of toggle switch; It two is operating state control sections of indication and control master controller H1, and this part is made of power supply indicator, communication indicator light, coding key.Can push button when the needs recompile, central processing module detects actuation of keys promptly can enter encoding state; Power supply indicator is bright when master controller H1 is in power supply state; The indicator light of communicating by letter when master control is being transmitted data 0 (low level) with branch control is bright, otherwise goes out; Can also increase display screen and keyboard in case of necessity except that these two parts commonly used changes variation patterns at any time to make things convenient for the user.
Allow whole tree lamp system correctly show required variation patterns, each extension set must have correct numbering.Adopt the autocoding mode that each extension set is numbered in the present embodiment.
Master controller H1 sends interrupt requests for each sub-controller EX by output module through holding wire D1 earlier during automatic numbering, and sub-controller EX enters the interruption accepting state after receiving request.Master controller H1 sends particular data through holding wire D2 to each sub-controller EX more then, and this process of transmitting repeats with certain frequency.Each sub-controller EX whenever receives a secondary data, numbering increases by 1, finish information encoded if received before this that the serial signal line D3 that connects a sub-controller EX (for first sub-controller EX then be master controller H1) sends, then this sub-controller EX finishes numbering and is sent completely coded message to next sub-controller and finishes number of repetition up to master controller H1, and this number of repetition is provided with in advance by the man-machine interactively module.After coding was finished, numbering can be stored in the memory storage module of each sub-controller EX.Therefore if changing, sub-controller EX state then not need not to encode once more.
During variation, the flow chart of master controller H1 and sub-controller EX such as Fig. 4, shown in Figure 5, the central processing module of master controller H1 extracts the various parameters of variation patterns in the memory storage module and it is handled, pass through output module then, send interrupt requests for each sub-controller EX through holding wire D1, sub-controller EX enters the interruption accepting state after receiving request.Master controller H1 sends data through holding wire D2 to each sub-controller EX again.Each sub-controller EX does not handle output after receiving data immediately, but just can handle according to data parameters of receiving and numbering separately behind the lock-out pulse that master controller H1 sends by D2 by the time, and the result is reflected to driver module.And before the every processing once of each sub-controller EX in the middle of the whole variation process, all can wait for the lock-out pulse that master controller H1 sends, finish up to current variation.Master controller H1 reads the parameter of next variation again, and sub-controller EX then is in the wait interrupt status once more, and so circulation endlessly.
Mentioned above a kind of situation in being to use, in fact each part all more has scheme available, because can't all embodiments of limit, below only selects several main aspects to remark additionally:
One, anti-interference
When improving the interference free performance of system, needs also should between output triode in the output module of master controller H1 (Q801) and central processing module, add optical coupling isolation circuit, as Fig. 9.Wherein GND2 communicates with the power supply ground of all sub-controller EX, and GND then is the power supply ground of (comprising central processing module, man-machine interactively module, memory storage module) of other parts in the master controller.It by one independently power supply provide, as can in master controller H1, increasing a 9V small transformers, circuit as shown in figure 10 is set thereafter.
Two, the output interface of master controller
Each output module of master controller H1 can be drawn a plurality of output interface P3, that is to say same road signal identical signal of demultiplexing after entering module, but signal that ought wherein some interface P3 goes wrong, then so long as the interface that this module is drawn generally all can go wrong the concrete condition concrete analysis.
Master controller also can have a plurality of output modules, and these modules are independently of one another but signal source is identical, just say that also same road signal demultiplexing before entering module enters a plurality of output modules.
Three, the connected mode of controller
Mode commonly used also has sub-controller EX join end to end mode such as Fig. 3.Input module on the sub-controller EX is drawn an interface P1, and P1 can dock with the output interface P3 of master controller H1, maybe can link together by another line.
Draw an output interface P2 on the sub-controller EX again, P2 can dock with minute input interface P1 of control, maybe can link together by an other line.When system adopted the autocoding mode, the D3 signal among the P2 was connected on the output module of sub-controller EX, directly docking one by one among other line and the input interface P1.
During practice of construction, the input interface P1 of each sub-controller EX docks with previous sub-controller EX output interface P2, or links together by another line.The input interface of the sub-controller EX in foremost docks with the output interface P3 of master controller H1 or links together by another line, and the output interface P2 of last sub-controller is vacant need not.
Four, what sub-controller was numbered obtains
Autocoding makes installs more simple and fast, but it makes whole system additionally increase a serial signal line D3.
The also available if necessary replacement autocoding that manually is provided with, at this moment serial signal line D3 can omit.At this moment system's (when each sub-controller EX and tree lamp TL carry out when independently-powered, positive source line S can not want yet) except 2 power line S, S0, only remaining two parallel holding wires of D1, D2, thus reduce the failure rate of system.It is what to be undertaken by the encoding setting module CO on the sub-controller that numbering manually is set, as Fig. 6, the encoding setting module can be made of a toggle switch that is connected on the central processing module, only needs to adjust toggle switch by binary system during use and just can obtain required numbering.
Five, LED driver module and the connected mode of setting lamp
A sub-controller EX can have a plurality of LED driver modules, each driver module separate electric (control signal is also independent), each LED driver module is equivalent to the switch that a route central processing module is independently controlled, each switch can be controlled many group LED lamps, and these LED lamp groups are not must be on the same tree lamp.
So-called LED lamp group is meant on the tree lamp, and other LED lamp group can independently be controlled and the combination of the LED that can not independently control each other relatively.For example, a tree has the LED of 6 kinds of different colours on the lamp, but the lamp of these 6 kinds of colors all links together, and is bright together or go out together, and then this tree lamp has only a lamp group.Have only a kind of LED of color and work as a tree lamp, but but can be divided into 6 parts controls respectively, then this tree lamp has 6 lamp groups.
Six, the power supply plan of system
The power supply plan of system depends mainly on the electric power thus supplied of tree lamp:
1, the tree lamp low-voltage DC supply of DC3V-DC36V, voltage commonly used has DC12V, DC24V; Can be competent at fully for these situations system configuration mentioned above, the distance between lamp is short but its prerequisite is each tree, and tree lamp power is little, otherwise because electric current is too big or the line resistance causes on the line pressure drop big too greatly, impact effect.And the power of a power supply also can not be infinitely great.Can adopt separately power supply plan this moment, can be that a tree lamp is joined a power supply according to concrete condition, also can be that adjacent several tree lamp is joined a power supply, but the output negative pole S0 of each power supply must be connected together, otherwise signal cannot transmit.And anodal S must have the place that communicates scarcely, otherwise will make whole system produce imponderable consequence.
2, the tree lamp uses the high voltage that come by the direct rectification of civil power, according to the various places situation two kinds of 220V or 110V is arranged generally.System configuration mentioned above in this case will be changed slightly, for security consideration sub-controller EX and master controller H1 still adopt low-voltage DC supply (by S0, S), the LED driver module can adopt circuit as shown in figure 13, and wherein the effect of optocoupler is that power supply of tree lamp and sub-controller power supply are isolated.When the P1.1 place is high level, the Q901 conducting, tree lamp lamp group is equivalent to be connected between 220V or the 110V, and lamp is bright, otherwise lamp goes out.Rectifying part such as Figure 12 of the power supply of tree lamp also can be installed in the branch control together.
Seven, the voltage of the actual use of each module among master controller H1 and the sub-controller EX
There is not inevitable relation in the voltage of the actual use of each module with the supply power voltage of tree lamp TL among master controller H1 and the sub-controller EX.It depends mainly on the voltage of the central processing element (single-chip microcomputer) in the central processing module, DC3.3V is generally arranged, DC5V etc. are several, and the power module of each controller will to enter the voltage transformation of controller just be needed voltage, should be higher than required voltage 3V at least if use 3 end pressurizers to carry out the voltage that conversion then enters controller.So if use the single-chip microcomputer of DC5V, the power supply plan of the 6th of then remarking additionally tree lamp, the minimum DC8V that should be of dc low-voltage that described sub-controller EX of second and master controller H1 adopt, general DC12V or the DC24V of using in the reality.
