For example, when a motion is detected, a packet for a token is transmitted to the gateway 140, and the packet type corresponds to a TOS_Msg rule, which is a basic message of TinyOS, an off-source operating system used for a wireless sensor network (WSN). In this case, the node ID is inserted in the payload.

For example, in a typical rectangular residential space, two temperature detectors 120 may be disposed one at a diagonally facing corner. Alternatively, only one can be placed in the central ceiling area.

The temperature sensor module is a component that periodically detects the temperature and delivers the result to the wireless communication module. The temperature sensor module includes a temperature sensor and a timer. The temperature sensor detects the temperature of the living space according to the time interval set in the timer. Will be transmitted to the wireless communication module.

Each temperature sensor module is configured to identify which temperature sensor module is installed in which position an identification number is assigned, and for example, each temperature sensor module may be designed to have a node ID.

Preferably, the sensing result processing method of the temperature sensor module may be of course adopted other methods to suit the purpose of the present invention.

The wireless communication module included in the temperature sensing means 120 is designed to basically follow the same operating system and message rules as the wireless communication modules included in the motion sensing means 101 to 10n.

The wireless communication module included in the temperature sensing means 120 is designed to include a predetermined number of temperature sensing results in the payload according to the setting.

As an example, the result of sensing the temperature periodically 10 times by a timer is designed to be inserted into the payload.

The wireless communication module included in the humidity sensing means 130 is designed to basically follow the same operating system and message rules as the wireless communication module included in the temperature sensing means 120.

The wireless communication module included in the humidity sensing means 130 is designed to include a predetermined number of humidity sensing results in the payload according to the setting.

Preferably, the number of times to be inserted into the payload is determined to correspond to the period set in the timer.

The gateway 140 is a means for controlling the heating to maintain the optimum temperature as a result of the integrated calculation by receiving the detection information of the motion detecting means 101 to 10n, the temperature detecting means 120 and the humidity detecting means 130. .

In addition, it is a means for controlling the heating to calculate and maintain the optimum temperature by using together with the optimal temperature database according to the characteristics of the space and the season already stored.

In addition, the user provides a setting screen interface such as setting the temperature, humidity and movement frequency directly, or setting hot water temperature, and controls the heating accordingly.

The gateway 140 includes a calculation module, a setting module, a memory module, a control module, and a communication module.

The calculation module is designed to calculate the motion frequency for each living space by using the motion detection information transmitted from the motion sensing means 101 to 10n installed in the various living spaces. For example, the motion frequency may be calculated by integrating motion detection information reached within a certain time from the motion detection means installed in a particular living space, and the motion detection information transmitted from the four motion detection means installed in the living room is within a certain time. The frequency of movement can be calculated from 0% to 100% depending on the transmission.

Here, the frequency of movement functions as an index corresponding to the amount of activity of the occupants. For example, when the frequency of movement is within 5% to 10%, the heating frequency is judged to be a signal to continuously stay in a specific space. For example, if 10% to 50% is used as the general activity of the occupant, the heating is mainly controlled according to other variables, and if it exceeds 50%, it means that the activity is increased. The heating is controlled in the direction, and if the frequency is more than 10% and the frequency is 0% for a long time, it means that the occupants do not occupy the space, so the heating is stopped.

Preferably, the numerical value of the frequency of movement can be further subdivided so that the amount of activity can be determined and the appropriate temperature can be matched with it.

Preferably, the calculation formula for calculating the motion frequency and the data for the appropriate temperature corresponding to the motion frequency are configured to be stored in advance in the calculation module or the memory module.
For example, as described above, the motion sensor module included in the motion detection means has a node ID. When a motion is detected, the wireless communication module included in the motion detection means transmits a packet for a token to the gateway 140. The node ID is inserted into the payload.
Therefore, the number of motion detection information that arrives within a certain time can be seen how many times the motion sensor module has detected a certain time.
Preferably, the reference value for calculating the number of transmissions from 0% to 100% for a predetermined time may be determined by using a statistical approach that is generally used as an example.

After calculating the movement frequency, the calculation module calculates the optimized temperature by integrally calculating the temperature sensing information transmitted from the temperature sensing means 120 and the humidity sensing information transmitted from the humidity sensing means 130.

For example, if the movement frequency is 10% to 50%, the general activity of the occupant is calculated, and thus the optimized temperature is calculated from the current temperature and humidity, and when the movement frequency is 50% or more, the optimized temperature data is mainly optimized. The temperature is calculated.

Preferably, the calculation formula for the integrated operation of the movement frequency, temperature and humidity and the data for the appropriate temperature corresponding to the temperature and humidity are configured to be stored in advance in the calculation module or the memory module.

Preferably, a method of integrating motion frequency, temperature, and humidity may be designed in various ways, such as weighting each variable based on the motion frequency or weighting each variable based on the temperature. .
For example, if the frequency of movement is 10% to 50%, a weight of temperature and humidity may be increased, and if the frequency of movement is 50% or more, a weight may be increased.

After calculating the movement frequency, the calculation module calculates the temperature sensing information transmitted from the temperature sensing means 120 and the humidity sensing information transmitted from the humidity sensing means 130, but includes a seasonal database constructed in the memory module and Additional integrated calculations of the residential space database can yield optimized temperatures.

The seasonal database contains temperature data for the four seasons of spring, summer, fall, and winter, for example, analyzing the spring season average temperature data over the past 10 years and covering a range of around 25 degrees, which is generally considered to be comfortable. Compared to, but by adjusting the comfortable temperature to match the average temperature of the spring season, the human body can calculate the optimized temperature more compliant with the natural environment.

Preferably, the seasonal database can be designed not only to include seasonal data but also to include data broken down by month or by season (15 days).

The living space database contains appropriate temperature data corresponding to living rooms, large rooms, and small rooms.For example, living rooms with the most utilization and large spaces, such as family members taking a break and interacting with each other, can respond to a slightly warm temperature. For example, a small room with low utilization and a small space can contain temperature data such as matching a slightly cool temperature.

Preferably, the small room is further subdivided by the size of the space to correspond to the appropriate temperature or the database can be constructed by functionally classifying the appropriate temperature to correspond to the appropriate temperature and not by dividing the space into sizes such as the large and small rooms. Of course.

Preferably, the method of integrating the motion frequency, temperature, humidity, seasonal database, and living space database may be performed in various ways such as weighting each variable based on the frequency of movement or weighting each variable based on the temperature. Of course, it can be designed.
For example, if the frequency of movement is 10% to 50%, the weight of the temperature, humidity, seasonal database, and residential database may be increased. If the frequency of movement is 50% or more, the weight may be increased.

The setting module provides a setting screen interface to the gateway so that the user can set the target temperature, and the target temperature is transmitted to the calculation module so that the heating can be controlled to be close thereto.

2 is an example of the main screen of the gateway of the intelligent heating system according to an embodiment of the present invention, the setting module provides such an interface.

As shown in FIG. 2, when each living space is selected, information on temperature, humidity, and movement frequency is displayed.

In addition, when the automatic setting button is pressed in FIG. 2, the calculation module calculates the optimized temperature by integrating each variable, and when the manual setting button is pressed, the target temperature is set for each living space as shown in FIG. 3, or As shown in Figure 4 it is possible to set the temperature of the hot water.

2 to 4 are merely examples of the present invention, but it is obvious that the present invention is not limited thereto.

Preferably, the setting module may be designed in various ways, such as setting the bedtime or study for each living space in addition to the target temperature of each living space.

The memory module may include a seasonal database and a residential space database, and may include various types of expressions and temperature and humidity data used in the calculation module.

In case of automatic setting, the control module receives the current temperature information provided from the calculation module and integrated optimal temperature to control heating to the optimum temperature.In the case of manual setting, the control module receives the current temperature information from the calculation module. The heating is controlled to the target temperature by receiving the target temperature from the setting module.

The communication module included in the gateway 140 is a component that receives a control signal from the control module and transmits the control signal to the valve adjusting means 150. The motion sensing means 101 to 10n, the temperature sensing means 120, and the humidity sensing means are provided. The same module as the wireless communication module applied to the 130 may be applied or may be configured by wire.

The valve control means 150 is a means for adjusting the heating valve connected to each living space in the heating device, and includes a valve control module and a communication module.

The valve control module receives the control signal from the gateway 140 and delivers the control signal to the valve control module, and the valve control module adjusts a heating valve connected to each living space.

Preferably, the valve control module may be designed as a means capable of relaying or switching to control the steam valve.

Preferably, the communication module may be designed by using the same type as the communication module of the gateway 140 or by a configuration capable of receiving only.
