The invention is realized by a combination of electronic control technology and optical technology.

Referring to Figure 1, a system architecture of one embodiment of an LED sun and moon simulation system provided by the present invention is illustrated. As shown in the figure, the system has a simulation control unit 200 as a control core, and a mode selection unit 500, a timer 400, a mode storage unit 300, and an LED sun and moon simulation implementation device 100 coupled thereto.

The LED sun and moon simulation implementation device 100 is a terminal device that specifically implements LED day and month simulation. Environmental elements include elements that exert influence on a person's sensory organs, such as an effect of a light element on a human visual organ; a sound element exerts an influence on a human auditory organ; and a taste element exerts an influence on a human olfactory organ. Of course, it also includes elements that exert influence on the tactile organs. In a simulation environment, one environment element, such as a light element, can be simulated separately, or multiple environmental elements can be simulated simultaneously. In this preferred embodiment of the invention, three of the environmental elements are employed: light, sound and scent. Specifically, the LED sun and moon simulation implementation device 100 includes an LED light source array 110, a sound device 120, and an odor device 130. The LED light source array 110 is a device that provides light elements. LED light source is the main light source in the future, which has long life, energy saving, shockproof and environmental protection. Moreover, it is possible to control the light variation parameters such as the light intensity and the chromaticity of the light by controlling the magnitude and length of the current flowing through the LED, thereby making it possible to automatically control the light source. Of course, other automatically controllable light sources are also possible. By controlling the light intensity and chromaticity of the LED light source array 100, and simulating the light environment elements of various environments by selecting the LEDs, for example, it is possible to simulate sunny mornings, mornings, noon, afternoons, dusks, and nights. Light environment. The sound device 120 is an automatically controllable device pre-stored with a plurality of simulated sounds (such as bird sounds, stream sounds, etc.) or a plurality of music for simulating sound elements in the environment. The scent device 130 is pre-installed with different odor emission devices, and can control the odor elements in the environment by controlling the heating and heating of a device to automatically control the emission of different odors.

The mode selection unit 500 is coupled to the human machine interface 600. The human machine interface 600 can be an input device such as a keyboard, and the user can input a mode selection signal through the human machine interface 600. The mode can be preset, for example, you can set the natural environment mode such as sunny or rainy day, you can also set the normal indoor lighting mode, and you can also set the demonstration mode. Of course, you can freely set any desired mode. The mode selection unit 500 sends the received mode selection signal to the simulation control unit 200.

The timer 400 is used to generate a system time that is sent to the simulation control unit 200.

The mode storage unit 300 is configured to store a mode policy. Each mode policy corresponds to one of the mode selection signals. The mode policy uses the system time as a policy condition to adjust the parameters of the LED sun and moon simulation implementation device as the policy content. That is, each policy corresponds to a policy table, and each policy table includes two parts: a policy condition and a policy content. For example, the following table is a policy policy table: Policy condition strategy content

6:1:16 o'clock Adjust the LED light source to be the strongest (for example, the current value is the maximum), the chroma is the twilight white; adjust the sound to the bird; adjust the smell to the floral.

16:1:19: Adjust the light intensity of the LED light source to be weak, the color is reddish; adjust the sound to light music; adjust the smell to the earth's aroma.

19:1 to 6:00 Adjust the LED to light the interval, the light intensity is the weakest, the color is white; adjust the sound to none; adjust the smell to none.

That is, each strategy is a two-dimensional table, and these policies can be stored in the pattern storage unit 300 in advance, and can be added, deleted, and modified at any time.

Referring to Fig. 2, the detailed structure of the simulation control unit 200 in the system shown in Fig. 1 is illustrated. As shown, the simulation control unit 200 includes a mode selection signal receiving device 210, a mode policy selection device 220, a system time reading device 230, and a mode policy execution device 240.

The mode selection signal receiving device 210 is configured to receive a mode selection signal from the mode selection unit 500 and send the signal to the mode policy selection device 220.

The mode policy selection means 220 selects a mode policy corresponding to the mode selection signal stored in the mode storage unit 300 based on the received mode selection signal, and sends the policy to the mode policy execution means 240.

The system time reading device 230 sends the system time read in the timer 400 to the mode policy execution device 240. The system time reading device 230 can set a certain reading frequency and automatically read. For example, it can be set to read every hour or every 10 minutes.

The mode policy enforcement device 240 executes a specific policy based on system time and policy content. The simulation control unit 200, the mode selection unit 500, the mode storage unit 300, and the timer 400 may be integrated in one electronic chip, or may be implemented independently. The control logic device in the simulation control unit 200 (ie, the mode selection signal receiving device 210, etc.) can be implemented by software or by Hardware or firmware implementation.

The flow chart of the natural LED sun and moon simulation method provided by the present invention is shown in FIG. The method includes the steps of:

S301: The environment mode is selected by the mode selection unit, and the automatic control system receives the mode selection signal;

S302: Select an environment mode policy corresponding to the environment mode in the mode storage unit.

S303: Read the system time in the timer, and execute the environment mode policy according to the system time, where the mode policy is a real-time control LED sun and moon simulation implementation device, to implement environment simulation.

Referring to Figure 4, a detailed flow of one LED day and month simulation based on the system of Figure 1 is illustrated. As shown in the figure, the process includes the steps:

S410: Select an environment mode to be a sunny mode;

S411: Select a sunny mode policy corresponding to the sunny mode in the mode storage unit;

S412 - S424 is a specific step of implementing a sunny mode strategy, including:

S412: If the system time is from 6 o'clock to 9 o'clock, step S413 is performed; otherwise, step S414 is performed;

The above policy content can be changed according to preferences.

It can be seen that the execution of the strategy starts after the selection mode, and the various policy contents are executed in an infinite loop in a 24-hour cycle, and the following selection mode is the end condition.

If the simulation is more realistic, you can make the time division more fine, for example, by setting different simulation strategies for different hours at intervals of hourly, you can better feel the simulation environment without any transition. .

In addition to the sunny mode, it can also simulate the rainy days. It can not only simulate the light environment of the rainy day through the LED light source array, but also control the LED light source to make lightning effect, and cooperate with the sound device to make thunder and wind and rain sound, specific mode strategy. Those skilled in the art can fully implement the above description with reference to the above description. Now, we will not repeat them here.

There is also a general lighting mode, in which the strategy content is very simple, and it is sufficient to control the light intensity and chromaticity of the LED light source in general illumination. In this mode, the simulation system is compatible with prior art lighting systems.

It can also be an exemplary mode, which simulates a 24 hour environment in a short period of time, so that it can be completed in a short time during the demonstration.

Of course, there are more modes that can be implemented by adding a mode policy.

Referring to Fig. 5, a system configuration of another embodiment of the LED day and month simulation system provided by the present invention is illustrated. Referring to Fig. 1, in comparison with the embodiment shown in Fig. 1, this embodiment has one more human body data collecting unit 700 than in Fig. 1.

Specifically, the user of the system can input the sensation statistical report to the human body data collecting unit 700 according to the comfort of the body, and the human body data collecting unit 700 can report the sensation statistical report to the simulation control unit 200 to enable the simulation control. The unit 200 can adjust the LED sun and moon simulation implementation device in real time to increase the flexibility of the system.
