Abstract

PURPOSE:To control a behavior without being known by a person by intentionally controlling person's warm comfortableness without being known. CONSTITUTION:The output of an M series signal generator 4 for generating a time series random number or quasi-random number and the output of a low-pass filter 5 inputting the output of the generator and having primary delay characteristics are selectively switched by a switch 2. The output of the switch 2 is added to a reference set value by adding means 6 to control an air conditioner 1. Since the output of the generator 4 obtains a signal of a power spectrum having a uniform distribution of a frequency range and the output of the filter 5 obtains a signal of a power spectrum having an inclination of 1/f to a frequency (f), a behavior can be controlled by varying comfortableness without being known by a person by selectively employing two fluctuations.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning control device for controlling behavior by controlling a psychological state of human comfort.

[0002]

2. Description of the Related Art Generally, in restaurants and the like, the number of customers and the turnover rate of customers are affected by the temperature of the air conditioning.

Conventionally, this type of air conditioning control device has a structure as shown in FIG. The configuration will be described below.

As shown in the figure, the set temperature of the air conditioner 1 is given through the switch 2, and the switch 2 can select an appropriate temperature and a lower temperature. Information for selection is given from the fuzzy reasoner 3. Fuzzy reasoner 3
Then, as shown in the membership function 3a, it is inferred to lower the set temperature in order to increase the turnover ratio of customers in the store when the number of customers is large, and when the number of customers in the store is small,
It is inferred to have an appropriate thermal environment. When the number of customers is small, the customers in the store stay for a long time so that new customers can easily enter. If there are many customers, it will be troublesome for some to stay longer, so the set temperature should be lowered. As the set temperature decreases, the feeling of not wanting to stay longer increases. Therefore, the rotation of the customer becomes faster. On the other hand, when the number of customers is small, the temperature for comfort is increased to increase the desire to stay longer. As a result, it is possible to avoid a situation where there are too few customers in the store and new customers are difficult to enter. Also, in the example of FIG.
Although the method of switching the switch 2 using the fuzzy inference has been described, a person can directly operate the switch 2 as a simple method.

[0005]

However, if the set temperature is lowered, the long-living customer becomes cold and uncomfortable and thus does not stay longer, but it is easily known to the customer that the setting has been changed. Therefore, the impression of the store is deteriorated. As described above, there is a problem in that it is obviously not preferable for the person whose behavior is controlled to notice that the behavior is controlled.

The present invention solves the above-mentioned problems. For example, in a restaurant, the air-conditioning temperature is intentionally controlled without letting the customer know the thermal comfort level of the customer, so that the number of customers in the shop can be appropriately maintained. The purpose is to do.

[0007]

In order to achieve the above object, the present invention provides a random number generating means for generating a time-series random number or a pseudo-random number, and an output of the random number generating means, which has a low first-order lag characteristic. A band pass filter, a switch for selectively switching the output of the random number generation means and the output of the low pass filter, an addition means for adding the output of the switch to a reference set value, and control by the output of the addition means The air conditioner is provided as a means for solving the problem.

[0008]

According to the present invention, the output of the random number generating means can obtain a power spectrum signal having a uniform distribution in the frequency domain, and the output of the low-pass filter is 1 / the frequency f. A power spectrum signal having a slope of f can be obtained. By selectively switching these two signals with a switch and adding them to the reference set value to control the air conditioner, it is possible to control the psychological state of human comfort and control the behavior. For example, in a restaurant, when the number of customers in the store is small, 1 for the frequency f
By changing the reference set value by the signal of the power spectrum having the slope of / f, the thermal comfort is improved and the desire to stay longer in the store is increased, and conversely, it is uniform in the frequency domain. By changing the reference set value according to the distributed signal, the thermal comfort level decreases, and the customer's desire to leave the store unintentionally increases. This makes it possible to control the number of customers in the store.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. The same components as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in the figure, an M-sequence signal generator (random number generation means) 4 generates an M-sequence signal such as a time-series random number or a pseudo-random number, and the M-sequence signal has a maximum period sequence (Ma).
ximum Period Sequence) signal, which is a kind of pseudo-random number signal, and its specific generation method is as described in Kashiwagi et al. “Measurement and Control” Vol.20, No.2, pp236-245,
It is a periodic signal that can be realized very easily by a shift register and an exclusive OR circuit. The output signal of the M-sequence signal generator 5 is input to the terminal B of the switch 2 via the primary low-pass filter 5 and directly to the terminal A of the switch 2. The output of the switch 2 is added to the reference set value by the addition means 6 and input to the air conditioner 1 to be input to the air conditioner 1
It is used as information for controlling the set temperature of. The reference set value is, for example, a temperature set value that is required from a comfortable thermal comfort.
The switching control of the switch 2 is performed according to the inference result of the fuzzy inference unit 3. The antecedent part of the fuzzy reasoning device 3 is the number of customers in the store, and the consequent part is the switching degree of the switch 2. As shown by the membership function 3a, the content of the inference is such that when the number of customers is large, it is controlled to the A side, and when it is small, it is controlled to the B side.

The operation of the above structure will be described with reference to FIG. 2. In FIG. 2, the two terminals A and B of the switch 2 are shown.
2 shows the power spectrum of the signal inputted to the terminal A, which is the signal of the M-sequence signal generator 4 at the terminal A.
As shown in (a), the power spectrum on the logarithmic frequency axis is uniform. On the other hand, at the terminal B, the same signal is connected via the first-order low-pass filter 5,
As shown in Fig. 2 (b), the power spectrum is small at "-20dB / decade" at medium and high frequencies, so-called 1 / f.
It is a characteristic signal. The 1 / f characteristic is the same as the fluctuation in the natural world, and it has been found that this fluctuation is comfortable for humans. On the other hand, the fluctuation as shown in FIG. 2A has a large high-frequency component, and it can be said that the fluctuation is faster than necessary. That is, by giving such fluctuations, the thermal comfort of human beings becomes over-vibrated, and the calmness of the mental state is reduced. The cause of this situation is unknown to the person himself.

By selectively using the signals having the two types of characteristics shown in FIG. 2 to generate fluctuations, it becomes possible to control human behavior. That is, when the number of customers in the store is small, the customer can stay longer by controlling the 1 / f fluctuation, and when the number of customers is small in the store, the customer can stay longer by controlling the uniform fluctuation. Can be controlled not to.

In the above embodiment, the number of customers in the restaurant was controlled, but the invention can be used to encourage the unwelcome visitors in a general household to return home. Further, in the present embodiment, the set temperature of the air conditioner is made to fluctuate, but it goes without saying that it can be carried out by making the air volume fluctuate instead of the set temperature.

[0014]

As is apparent from the above embodiments, according to the present invention, a random number generating means for generating a time-series random number or a pseudo-random number and a low-order delay characteristic having an output of the random number generating means are inputted. A band pass filter, a switch for selectively switching the output of the random number generation means and the output of the low pass filter, an addition means for adding the output of the switch to a reference set value, and control by the output of the addition means It is possible to control the behavior by controlling the psychological state of human comfort in a very simple way because it is equipped with an air conditioner that is operated. It can be controlled intentionally without being known to the customer, and the number of customers in the store can be appropriately maintained.
