Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of Lighting Control Assembly and the control method that the utility model proposes are described in further detail.
Please refer to Fig. 1, is the structural representation of a preferred embodiment of a kind of Lighting Control Assembly that the utility model proposes shown in Fig. 1, and this system comprises an illumination monitoring modular 1, control module 2 and performance element 3.Illumination monitoring modular 1 comprises at least one optical sensor, by light sensors ambient light illumination, obtains illumination data.Performance element 3 can be one or more lighting apparatus, as street lamp, ceiling light etc.Control module 2 connects illumination monitoring modular 1 and performance elements 3, receives from the illumination data of illumination monitoring modular 1 and input signal is carried out to calculation process to produce all kinds of control commands.Performance element 3 can have light, close, different photochromic, different multiple operating states such as brightness, these can be controlled by the control command of control module 2.The control command that performance element 3 receives from control module 2, and change between each operating state according to these control commands, as control module 2 is sent the order of turning on light, performance element is lit a lamp and is entered the state of turning on light.Fig. 1 is only structural representation, and whole Lighting Control Assembly also may comprise other parts, and control module 2 can also connect other sensor devices, obtains temperature data etc., even by DMX512 agreement, Zigbee agreement, obtains external control information.What the present embodiment was mainly paid close attention to is according to ambient light illumination, to carry out the switch control of light fixture, therefore performance element 3 only has these two kinds of operating states of turning on light and turn off the light in the present embodiment, when here we claim to turn off the light, being closed condition, is the first operating state while turning on light.
Control module comprises following components in the present embodiment:
Memory module 201, storage is carried out threshold values and is closed threshold values, and the execution threshold values here and to close threshold values be all brightness value is according to the erecting bed value that bright needs set in advance of taking a group photo.Closing threshold values can recalculate when Lighting Control Assembly actual motion.But for preventing from moving first, cannot close, still set in advance one and close threshold values in system initialization, this value can be equal to or greater than execution threshold values;
Comparator 202, the illumination data that illumination monitoring modular 1 is recorded compares with carrying out threshold values or closing threshold values;
Carry out arithmetic unit 204, read the operation result of described comparator 202, carry out computing and produce control command.Basic processing rule is to be less than execution threshold values when illumination data, light fixture is opened Lighting Control Assembly and is entered the first operating state, when illumination data is greater than execution threshold values, light fixture is closed Lighting Control Assembly and is entered closed condition, the variation of this state is sent control command by carrying out arithmetic unit 204 to performance element 3, and performance element 3 switches according to control command;
Close threshold values computing module 203, for calculate adapt to current environment close threshold values to obtain accurate control, the calculating of closing each time threshold values all need to be triggered by the control command of carrying out arithmetic unit 204, this order is sent after performance element 3 sends the order of turning on light at execution arithmetic unit 204 conventionally, close threshold values computing module 203 by the illumination measured value after turning on light through certain computing, produce the new threshold values of closing, and result is write to memory module 201.
The definition of each functional module in above-mentioned control module, only for convenience, from the angle of practical function, divide, be not they will be defined as to resolution element, these modules can be a single-chip microcomputer, a circuit (as comparison circuit) or components and parts, or just in IC chip, can realize a part of circuit of this function, and control module can be completely also, an independent chip that comprises these functions.
In Fig. 1, arrow has represented the data flow in native system, and as shown in the figure, illumination monitoring modular 1 produces illumination data, input comparator 202 and close threshold values computing module 203; Comparator 202 is from memory module 201 read datas, and operation result sends to carrying out arithmetic unit 204; Carry out arithmetic unit 204 from comparator 202 reading out datas, to performance element 3 with close threshold values computing module 203 and send control commands; Close threshold values computing module 203 and receive order from carrying out arithmetic unit 204, and write data to memory module 201.
Lighting Control Assembly in the present embodiment, because performance element has two operating states, when Lighting Control Assembly moves, these two states are carried out respectively two different program circuits, and flow chart is shown in Fig. 2, Fig. 3.
Fig. 2 is the workflow of Lighting Control Assembly in closed condition, illumination monitoring modular 1 is measured illumination, comparator 202 judges whether illumination data is less than the execution threshold values that is recorded in described memory module 201, when illumination data is more than or equal to described execution threshold values, described illumination monitoring modular 1 continues to repeat aforesaid operations, until the illumination data recording is less than execution threshold values, illustrate that ambient light illumination too secretly need to turn on light, now carry out arithmetic unit 204 and send control command to performance element 3, described performance element 3 receives described control command and enters the first operating state.When sending the order of turning on light, carry out arithmetic unit 204 and send control command to closing threshold values computing module 203, make it recalculate and close threshold values.Close threshold values computing module 203 and receive after order, calculate and close threshold values and the new threshold values of closing is write to memory module 201.The computational methods of closing threshold values design in advance, but all with turn on light after illumination data relevant, the illumination now recording is the superposition value of illuminance of lamp and ambient light illumination.In the present embodiment, close illumination data that threshold values computing module 203 directly reads illumination monitoring modular 1 as closing threshold values.The illumination data that more preferably repeatedly reads illumination monitoring modular 1 calculates a mean value and is used as closing threshold values.Certainly, also can take into account and turn on light using current illumination as closing threshold values, but now as long as surround lighting has increased slightly, the illumination recording will break through closes threshold values, forms the flicker situation of at once closing opening.When threshold values is closed in calculating, can also in the illumination recording, be used as closing threshold values by an increment size of amplitude calculating by a certain percentage.When closing threshold values, write after memory module 201, originally the default threshold values of closing is just replaced during Lighting Control Assembly initialization, by original estimated value, replace with accurate measured value, thereby Lighting Control Assembly can be had in different installation environments, close accurately threshold values.
Above process is that hypothesis light fixture is in a normal running environment, it is around natural daylight, so the variation of surround lighting be one bright or by the bright process Lighting Control Assembly to a dark gradual change still by secret tunnel, when powering on first, it is just in time a very dark environment, even if ambient light illumination has been superimposed with illuminance of lamp and has also still been less than default execution threshold values, will cause like this and close the situation that threshold values is less than execution threshold values, make ceaselessly switch of light fixture.In order to solve such problem, the utility model provides the second embodiment, and structured flowchart is shown in Fig. 4.Compare with previous embodiment, in control module 2, increase threshold values and calculated judge module 5, in memory module 201, store in addition judgment value, threshold values calculates judge module 5 comparing according to 202 pairs of illumination data from illumination monitoring modular 1 of described comparator and described judgment value, and according to operation result, to closing threshold values computing module 203, send module starting command, and close threshold values computing module 203 only when receiving module starting command, and just can close threshold values while having the control command of carrying out arithmetic unit 204 simultaneously and calculate.Idiographic flow is as follows: receive to calculate and close after the order of threshold values closing threshold values computing module 203, do not calculate immediately, but add a determining step F01 here, see Fig. 2, a default judgment value, judges whether current illumination is less than this judgment value.Be more than or equal to judgment value and carry out the operation of closing the calculating of threshold values and writing described memory module 201, otherwise skip, close threshold values calculation procedure, still retain the former threshold values of closing.When Lighting Control Assembly enters normal running environment, ambient light illumination all the time or the process of a gradual change, like this by bright in dark process, when illumination approaches critical point, the calculation procedure of closing threshold values can obtain operation, thereby obtains closing accurately brightness value.Here said judgment value is to add a definite value at execution threshold values, this definite value can be an estimated value, this definite value is the brightness value that performance element produces in the present embodiment, and the brightness value only recording after lighting a lamp is greater than this judgment value, just can recalculate and close threshold values.
Fig. 3 is the workflow of Lighting Control Assembly in the first operating state, and illumination monitoring modular is the same with closed condition or measure illumination, but the data that now contrast become, closes threshold values, and this closes threshold values is the data that were stored at that time memory module.Comparator judges whether illumination data is greater than the threshold values of closing that is recorded in memory module, illumination data is less than or equal to closes threshold values, illumination monitoring modular continues to repeat aforesaid operations, until being greater than, illumination data closes threshold values, show that environment brightens, do not need to have turned on light, carry out arithmetic unit and send control command to performance element, performance element receives the order of turning off the light and enters closed condition.
In the present embodiment, Lighting Control Assembly switches between in off position and the first operating state all the time, therefore the workflow in these two operating states is actually a continuous each other process, as shown in Figure 2 and Figure 3, the end node of closed condition, is exactly the start node of the first operating state, in figure, be expressed as B, and the end node of the first operating state is exactly the start node of closed condition, in figure, be expressed as A.
In above-described embodiment, performance element can be turned on light and turn off the light according to the bright moving secretly of environment, has both met the demand in people's focus ring border, has also saved the energy.But only according to environment, control light fixture, can cause the light fixture Chang Liang in unmanned situation, also can cause waste.The utility model also provides the 3rd embodiment to solve this problem for this reason.In the 3rd embodiment, thereby light fixture adopts LED light source can realize the adjusting of different brightness.The system architecture diagram of the 3rd embodiment is shown in Fig. 5, throw light on when having realized people, nobody time energy-conservation, in Lighting Control Assembly, increased a human body induction module 4, it can detect in field of illumination, whether there is people, and will detect transfer of data to the execution arithmetic unit 204 in control module.Human body induction module is infrared sensor in the present embodiment.The operating state of Lighting Control Assembly has also increased by the second operating state except closed condition and the first operating state simultaneously.Compare with the first operating state, during the second operating state, the brightness of performance element 3 is greater than the first operating state, and during the first operating state, performance element 3 is lighted, but only export a lower illumination, and performance element 3 output maximal illuminations during the second operating state.Such Lighting Control Assembly can be realized: when environment is bright, close performance element 3, and environment is when dark, if nobody only maintain one dark but be unlikely to invisible luminous environment, have people to realize a bright luminous environment.Concrete execution step in off position with the first embodiment is consistent, just repeats no more here.Difference is the executive program in the first operating state, particular flow sheet is shown in Fig. 6, on the basis of the first embodiment, increased personnel's determining step F02, concrete steps comprise: receive and judged whether people according to human body sensing data: have people, performance element 3 enters the second operating state, and continues cycle criterion and whether have people, until be judged as nobody described performance element 3 enter the first operating state.After personnel's determining step F02 finishes, illumination monitoring modular 1 is measured illumination, comparator 202 judges whether illumination data is greater than the threshold values of closing that is recorded in described memory module 201, as being less than or equal to, close threshold values and turn back to original position operational staff's determining step again, illumination data as contrary in situation is greater than closes threshold values, carry out arithmetic unit 204 and send control command to performance element 3, performance element 3 receives order and enters closed condition.
To the description of the utility model preferred embodiment, be above in order to illustrate and to describe, not want the utility model limit or be confined to disclosed concrete form, obviously, may make many modifications and variations, these modifications and variations may be obvious to those skilled in the art, within should being included in the scope of the present utility model being defined by appended claims.
