Description

Indoor number control system and indoor number control method

The present invention relates to an indoor number control system and an indoor number control method, and more particularly to an indoor number control system for controlling the number of people present in an indoor space using a carbon dioxide concentration value, and an indoor number control method.

Nearly 90% of Chinese people are in indoor space. The quality of indoor air quality directly affects human health and work efficiency. Among them, carbon dioxide is regarded as the most important chemical indicator of indoor air quality. The concentration of carbon dioxide is mostly related to personnel. Breathing is relevant, so controlling the number of people in the indoor space becomes an important way to manage air quality.

Generally speaking, the old treatment method will convert the number of people in the indoor space by the empirical value according to the area of the indoor space, and then announce the number of people in the indoor space of the place. Further, a person flow calculation module is installed in the entrance and exit of the indoor space, and the number of people present in the indoor space is also announced, and the number of people in the room and the number of people present are used to remind the person in the indoor space whether to evacuate to the outside.

However, this kind of experience comparison method is easy to be distorted. For example, if the indoor space is filled with a lot of equipment or goods, the actual volume has become smaller. In reality, the actual number of safe people can be accommodated is not the original limit number. In addition, just the indoor space. The people are all those who breathe faster, and the number of safe people who can actually be accommodated in the current situation is not as large as the original limit.

Accordingly, it is a primary object of the present invention to provide an indoor number control system and an indoor number control method for controlling the number of people present in an indoor space using a carbon dioxide concentration value to solve the above problems.

An object of the present invention is to provide an indoor number control system and an indoor number control method capable of maintaining the number of people present in an indoor space within a safe number of people in consideration of air quality.

The present invention relates to an indoor number control system for dynamically adjusting the number of people in an indoor space to prevent the carbon dioxide concentration value of the indoor space from exceeding a safety threshold. The indoor number control system includes a processing module, a storage device, a flow calculation module, and a carbon dioxide concentration detector.

The storage device is coupled to the processing module for storing the first limited number of people as a limit number of people and storing the security threshold. The flow calculation module is coupled to the processing module for calculating the number of people present in the indoor space. The carbon dioxide concentration detector is coupled to the processing module and is installed in the indoor space for detecting the carbon dioxide concentration value.

When the processing module determines that the carbon dioxide concentration value exceeds the safety threshold, the processing module will lower the first limit number of people to the second limit number and limit the number of people, wherein the second limit number is lower than the number of people present.

For example, the indoor number control system, wherein the flow calculation module is at least one image recognition module, is installed in the entrance and exit of the indoor space, and faces the flow of people passing through the entrance and exit, and calculates the flow of people by image recognition.

The invention also relates to an indoor number control method for dynamically adjusting the number of people in the indoor space in the indoor number control system to prevent the carbon dioxide concentration value of the indoor space from exceeding the safety threshold. The indoor number control method includes the following steps:

Store the first limit number of people as a limit;

Calculate the number of people present in the indoor space;

Detecting the concentration of carbon dioxide in the indoor space;

When the carbon dioxide concentration value exceeds the safety threshold, the number of people who are reduced by the first limit is the second limit number and is the new limit number, and the number of the second limit is lower than the number of people present.

Therefore, according to the indoor number control system and the indoor number control method provided by the present invention, by dynamically changing the number of people according to the carbon dioxide concentration value, the number of people present in the indoor space can be safely determined by the air quality. Within the scope.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of the operation of the indoor number control system of the present invention in the indoor space 10. The illustration shows an indoor space 10 with an inlet and outlet 12, a display 52 visible above the inlet and outlet 12, and a display 52 that can display a limit of 16 persons and a presence of 14. In order to avoid excessive number of people in the indoor space 10 and a large amount of carbon dioxide causing low air quality, it is necessary to display the number of persons 16 and the number of people present 14 so that the person in the indoor space 10 knows whether it is necessary to evacuate to the outside to improve the air quality. As shown in the figure, the number of people is 16 and 20, and the number of people present is 14 and it is obviously safe. The people in the indoor space 10 will continue to operate with peace of mind. On the other hand, when the person in the indoor space 10 sees that the number of people present 14 is greater than the limit number of people 16, the alarm can be raised with the alarm, and all or part of the personnel in the indoor space 10 will actively evacuate.

In order to calculate the number of people in the indoor space 10, an image recognition module 50 can be disposed at the entrance and exit 12, and the image recognition module 50 faces the flow of people passing through the inlet and outlet 12, and the image recognition technology is used to calculate the presence in the indoor space 10. The number of people is 14.

Please refer to FIG. 2. FIG. 2 is a schematic diagram showing the function association of the indoor number control system 30 of the present invention. The present invention is directed to an indoor number control system 30 for dynamically adjusting the number of persons 16 in the indoor space 10 to prevent the carbon dioxide concentration value of the indoor space 10 from exceeding a safety threshold. The indoor number control system 30 includes a processing module 32, a storage device 34, a human flow computing module 36, and a carbon dioxide concentration detector 38.

The storage device 34 is coupled to the processing module 32 for storing the first limited number of people as the limit number 16 and storing the security threshold.

The flow calculation module 36 can include the image recognition module 50, and calculate the number of people by the image. The flow calculation module 36 is coupled to the processing module 32, and can accumulate the number of people 14 in the indoor space 10 and display it on the display. 52.

The carbon dioxide concentration detector 38 is coupled to the processing module 32 and disposed in the indoor space 10 for detecting the concentration of carbon dioxide in the indoor space 10.

When the processing module 32 determines that the carbon dioxide concentration value detected by the carbon dioxide concentration detector 38 exceeds the safety threshold value in the storage device 34, the processing module 32 lowers the first limit number of people to the second limit number as a new limit. Number 16. For example, the approximate rate of the carbon dioxide concentration value and the safety threshold value in the most recent period is converted into a corresponding percentage value, and the percentage value is multiplied by the original limit number of people 16, so that a new limit number 16 can be calculated.

It should be noted that the newly calculated second limit number is less than the number of 14 people present. Otherwise, it is necessary to adjust the limit number 16 or change the percentage value. Because if the number of people in the second limit is not lower than the number of people in the 14th, the number of new restrictions 16 will not be able to alert the people in the indoor space 10, and no one will take the initiative to evacuate.

Please refer to FIG. 3. FIG. 3 is a flow chart of the indoor number control method of the present invention. The present invention is also an indoor number control method for dynamically adjusting the number of persons 16 in the indoor space 10 in the indoor number control system 30 to prevent the carbon dioxide concentration value of the indoor space 10 from exceeding the safety threshold. The indoor number control method includes the following steps:

Step 1 (S01): The indoor number control system 30 is activated.

Step 2 (S02): The first limited number of people is stored as the initial limit number of persons 16, and the number of persons 16 is displayed for reference by the personnel in the indoor space 10.

Step 3 (S03): Calculate the number of people 14 present in the indoor space 10, and display the number of persons 14 present, which is also referred to by the personnel in the indoor space 10.

Step 4 (S04): detecting the carbon dioxide concentration value in the indoor space 10, and determining whether the carbon dioxide concentration value exceeds the safety threshold value, and the safety threshold value may be multiplied by a predetermined safety according to the empirical value of the carbon dioxide concentration that can endanger the human body. The coefficient is used to make this security threshold. When the step S04 is NO, the above step two S02, the third step S03, and the fourth step S04 are repeated.

Step 5 (S05): When step S04 is YES, that is, the carbon dioxide concentration value exceeds the safety threshold, the first limit number is reduced to the second limit number and the new limit number is 16 and replaces the original limit number 16 The number of people who display this new limit of 16, is displayed for reference by the personnel in the indoor space 10. Among them, the second limit number of people needs to be lower than the number of people present 14 to make sense.

Therefore, according to the indoor number control system 30 and the indoor number control method provided by the present invention, the number of persons 16 in the indoor space 10 can be maintained by the air quality consideration by dynamically changing the number of persons 16 to be limited according to the carbon dioxide concentration value. It falls within the safe number of people.
