Description

A kind of series connection digital data transmission intelligent control system
Technical field
The present invention relates to a kind of control system of digital data transmission, specifically a kind of series connection digital data transmission intelligent control system for Smart Home and light fixture control.
Background technology
Switch, controllable silicon dimmer that traditional light control is used all cannot be taken into account simultaneously and not increase wire, control multiple lamps simultaneously, cannot realize a controller and in controlling several lamps, also can control separately each lamp simultaneously; Traditional brightness adjustment control mode increases wire, and efficiency is low, and cost is high, and dimming scope is little, and degree of depth light modulation there will be flicker, the shortcomings such as complicated are installed.
Lamp pass through wire-controlled controller with controllable silicon dimmer the most typical case, the mode of controllable silicon light modulation is by input AC is cut to ripple, the driving power of lamp detects input waveform again, thereby adjustment output current is controlled the brightness of lamp, this dimming mode is simple, and single lamp switch light modulation is easily realized.
The shortcoming of silicon controlled dimmer for light control is: cut ripple because of dimmer, cause input voltage distortion, thereby reduce input power factor PF, also cause conducted interference; Controllable silicon dimmer will normally be worked also needs a minimum load current, in the time of input voltage zero passage, normally works in order to maintain dimmer, extra load need be provided, thereby can reduce overall efficiency; In the time that lamp light modulation is the darkest, because of input voltage, to cut wave angle degree large, causes the low-frequency ripple that input is larger to be coupled on lamp, easily occurs the low frequency flicker that naked eyes can be seen, and causes the visual fatigue of human eye; A controllable silicon dimmer can be controlled multiple lamps and carry out switch or light modulation simultaneously, but can not, in controlling multiple lamps, control single lamp, reaching this object needs each lamp to be equipped with a dimmer, be equipped with independently wire, thereby cause the increase of cost, the waste of resource.
Summary of the invention
Technical problem solved by the invention is to provide a kind of light to regulate controllability good, and input cost is few, the series connection digital data transmission intelligent control system economizing on resources.
In order to solve the problems of the technologies described above, series connection digital data transmission intelligent control system of the present invention, comprise that AC turns power module SPS1 and a master controller K1 of DC, the input of power module connects Alternating Current Power Supply end, the output of power module connects respectively wire L+ and wire L-, on wire L-, be connected with a switch MOS pipe Q1, the G of the output of master controller K1 and switching tube Q1, the S utmost point connects, on wire L+ and wire L-, be parallel with multiple lamp sources with independent control, power module SPS1 negative pole is connected with each lamp by L-, the positive pole of SPS1 is connected with another utmost point of each lamp by switching tube Q1.
Described controller K1 mass-sends out signal instruction, form by wire L+, wire L-transmission mass-sending passes on multiple light fixtures, each light fixture is adjusted relative operating state again at the code of the operating state that receives oneself, master controller K1 can control separately the brightness of each lamp, colour temperature, and the state such as switch.
Described controller K1 sends signal code by the break-make of control switch metal-oxide-semiconductor Q1.
The invention has the beneficial effects as follows: the present invention and traditional light modulation scheme ratio, whole efficiency is higher, wire used still less, more easily operation, when dimming, light fixture there will not be flicker, obtain higher PF value, a controller can arbitrarily be controlled any one lamp in many light fixtures in the situation that not increasing wire, reduces cost; This circuit can be applied in stage, hotel's light control, family's light control, the light control on industrial premises production line.Can reach energy-conserving and environment-protective, reduce costs, simplified design, installs simply effect.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention's digital data transmission intelligent control system in parallel.
Embodiment
Below in conjunction with the drawings and specific embodiments, series connection digital data transmission intelligent control system of the present invention is described in further detail.
As shown in the figure, series connection digital data transmission intelligent control system of the present invention, comprise that AC turns power module SPS1 and a master controller K1 of DC, the input of power module connects Alternating Current Power Supply end, the output of power module connects respectively wire L+ and wire L-, on wire L-, be connected with a switch MOS pipe Q1, the G of the output of master controller K1 and switching tube Q1, the S utmost point connects, on wire L+ and wire L-, be parallel with multiple lamp sources with independent control, power module SPS1 negative pole is connected with each lamp by L-, the positive pole of SPS1 is connected with another utmost point of each lamp by switching tube Q1.
Described controller K1 mass-sends out signal instruction, form by wire L+, wire L-transmission mass-sending passes on multiple light fixtures, each light fixture is adjusted relative operating state again at the code of the operating state that receives oneself, master controller K1 can control separately the brightness of each lamp, colour temperature, and the state such as switch.
Described controller K1 sends signal code by the break-make of control switch metal-oxide-semiconductor Q1.
Its operation principle is as follows:
In the time of power module SPS1 access civil power, output DC power supply is by control switch metal-oxide-semiconductor Q1, wire L+, wire L-is transferred on each light fixture, each lamp interior is provided with the particular code of various operating states, the different pulse signal that the break-make of master controller K1 control switch metal-oxide-semiconductor Q1 forms also passes through L+, L-is transferred on each light fixture in the mode of mass-sending, master controller K1 sends the signal specific of the various operating states of various light fixtures by changing the break-make control code of switch MOS pipe Q1, each light fixture is by wire L+, wire L-receives the signal that K1 sends, and recognized decoding, and according to the corresponding operating state of the signal adjustment light fixture of receiving, if receive unidentified signal, light fixture will be failure to actuate.Controller K1 can control by manual operation the various operating state instructions that the break-make of Q1 is sent each light fixture.Therefore system is to mass-send signal transmission by power line L+, wire L-, do not need separately to add wire, can save the cost of wire, each lamp interior has the function of the own operating state instruction of identification, can realize a controller K1 and can control multiple light fixtures simultaneously, again save wire and simplify installing engineering, because all light fixtures are all to have shared an AC TO DC DC power supplier SPS1, this also can save cost; SPS1 is a DC power supplier, this there will not be light adjusting system to affect the phenomenon of PF, again because of light fixture use be galvanic current source, in the time that light fixture dims, there will not be the ripple of power frequency, thereby solve flicker and the inefficient problem of traditional controllable silicon light modulation.
More than show and described general principle of the present invention and principal character and advantage of the present invention; the technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and claimed scope of the present invention is defined by appending claims and equivalent thereof.
