Abstract

PURPOSE:To obtain a comfortable indoor environment by generating the voltage having the 1/f fluctuation with use of a random number train and securing the correlation of time changes among the illumination, the temperature, the air blast flow, and the dark noises in a room. CONSTITUTION:The random numbers are set 101 and at the same time the linear conversion coefficients aj (a1 - an) are set 102. Based on these set random numbers and coefficients, a q-series is produced as a numerical train having the fluctuation of about 1/f shown by an equation (n = 1, 2...). Then this obtained 1/f numerical train undergoes the D/A conversion 104. A 1/f fluctuating voltage generating circuit 105 produces the voltage having the fluctuation of about 1/f based on the analog value of the converted 1/f numerical train. The correlation is secured by the voltage of the circuit 105 among the illuminance 2a, the temperature 3a, the air blast flow 4a, and the dark noise 5a of a light source device 2, a temperature controller 3, a ventilator 4, and a dark noise generator 5 respectively. As a result, the residents can enjoy the comfortable feeling similar to a phenomenon of the natural world.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to indoor brightness. temperature. This article relates to a method for making indoor environments more comfortable in environments affected by air flow and background noise.

[Conventional technology]

In the past, efforts have been made to improve the indoor environment so that people can enjoy their lives, but although the aim is to rationalize it, it is far from a natural environment that gives a sense of pleasure, and the individual designers Lighting,
The reality was that the basic idea was to keep things like temperature constant.

[Problem to be solved by the invention]

However, the above-mentioned conventional indoor environment has a problem in that the general public does not necessarily sympathize with it and feel peace of mind.

The present invention has been made in view of the above problems. The present inventor has been conducting research on "1/f fluctuation" for many years, Journal of Applied Physics, 1965, 427-43.
Published a paper on ``Biological information and 1/f fluctuation'' on page 5,
In addition, in the Journal of the Precision Machinery Society, 1984, Vol. 50, No. 61, “
He has published a paper on ``Biological control and 1/f fluctuation''. The gist is that ``1/f fluctuation is a fluctuation that gives humans a comfortable feeling, and the reason why 1/f fluctuation gives a comfortable feeling is that the basic rhythm fluctuations of the human body have a 1/f spectrum.'' Another way to look at this is that humans get tired of receiving the same stimulation over and over again, and conversely, stimulation that changes too rapidly can actually cause discomfort. It is disclosed that the fluctuation is 1/f fluctuation.

The present invention was made based on the above research and results.
1/f fluctuation gives humans a comfortable feeling.

This principle is based on the principle that brightness and temperature due to indoor lighting. It is applied to the air flow rate and background noise, and creates approximately 1/f fluctuations in each, and also follows the law of nature that states, for example, when the brightness of lighting decreases, the temperature decreases, but the air flow rate and noise increase. The brightness. temperature. Air flow rate. An object of the present invention is to provide a method for making an indoor environment more comfortable by correlating the time changes between each approximately 1/f fluctuation of background noise.

[Means to solve the problem]

As a means for solving the above problems, the present invention provides a random number sequence Pt. Pz... is generated by a computer and is expressed as a linear series by qn-Σ ajPll-j (n=1.2...+, aj...linear conversion coefficient), which is a numerical sequence with approximately 1/f fluctuation. A q series is created, and the numerical value sequence is digital/analog converted into an analog information signal with approximately 1/f fluctuation, and the voltage is controlled by the analog information signal so that it has approximately 1/f fluctuation. A power supply circuit is created using the above power supply circuit, and the light source device, temperature control device,
This system is designed to correlate the time changes of each output signal of the blower and the background noise generator.

[Effect]

By the above means, the indoor illuminance can be calculated based on the q-sequence, which is a numerical sequence of random numbers with approximately 1/f fluctuation. Indoor temperature. In addition to providing a sense of comfort for people with the amount of air blown and background noise each having a fluctuation of approximately 1/f, each of the above four factors was made to have a correlation with the change over time, so illuminance, temperature, amount of air blown, and background noise changes according to the laws of nature, giving people a greater sense of comfort.
