Description

A kind of digital data transmission intelligent control system in parallel

Technical field

The utility model relates to a kind of control system of digital data transmission, specifically a kind of digital data transmission intelligent control system in parallel 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 carries out switch or light modulation when can controlling multiple lamp, 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 pilot, thereby cause the increase of cost, the waste of resource.

Utility model content

The technical problem that the utility model solves is to provide a kind of light to regulate controllability good, and input cost is few, the digital data transmission intelligent control system in parallel economizing on resources.

In order to solve the problems of the technologies described above, digital data transmission intelligent control system in parallel of the present utility model, comprise that AC turns the power module SPS1 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-respectively, on described wire L+ and wire L-, be connected with a master controller K1, be parallel with multiple sub-controller DIM on wire L+ and wire L-, the output of controller DIM is connected with respectively lamp source.

Described master controller K1 sends digital signal codes in the mode of broadcast, is transferred on multiple sub-controllers by wire L+, wire L-, and multiple sub-controllers are adjusted the operating state of lamp separately again by receiving master controller K1 signal instruction.

Described master controller by wire L+ and wire L-transfer instruction signal code to sub-controller.

The beneficial effects of the utility model are: the utility model and traditional light modulation scheme ratio, whole efficiency is higher, wire used still less, more easily operation, when dimming, lamp 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, and the light control on industrial premises production line, can reach energy-conserving and environment-protective, reduces costs, and simplified design, installs simply effect.

Brief description of the drawings

Fig. 1 is the schematic diagram of the utility model digital data transmission intelligent control system in parallel.

Embodiment

Below in conjunction with the drawings and specific embodiments, digital data transmission intelligent control system in parallel of the present utility model is described in further detail.

As shown in the figure, digital data transmission intelligent control system in parallel of the present utility model, comprises that AC turns the power module SPS1 of DC, master controller K1, sub-controller DIM1 ... DIMn, Lamp1 ... Lampn, wire L+, wire L-; Power module is provided with AC(L, N) incoming end, power module outlet be V+, V-, power module SPS1 output V+ is connected respectively wire L+, wire L-with V-, wire L+, wire L-connect respectively sub-controller DIM1 again ... the input of DINn, controller DIM1 ... the output of DIMn connects respectively Lamp1 again ... Lampn; Output two lines of master controller K1 are connected respectively on V+, V-again.

Its operation principle is as follows:

As shown in the figure, in the time of power module SPS1 access civil power, AC turns DC power module provides power supply to be transferred on each sub-controller by wire L+, wire L-, and each sub-controller processes and controls each light fixture again; Each controlled light fixture has the particular code of various states, master controller can send the code of the various states of each lamp, and be sent to by power line L+, L-on the sub-controller of each light fixture in the mode (mode of mass-sending) of broadcast, each sub-controller receives the signal code that master controller sends again, and can recognize the code of the operating state of the own lamp of controlling, and adjust the operating state of own lamp, in the time receiving the code of the operating state that is not own lamp, sub-controller does not move.Master controller K1 can send out the code of the operating state of each lamp by artificial operation, will on the power lead L+ of stack, wire L-, be transferred on the sub-controller of each lamp.

More than show and described general principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, that in above-described embodiment and specification, describes just illustrates principle of the present utility model, do not departing under the prerequisite of the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, claimed scope of the present utility model is defined by appending claims and equivalent thereof.
