Wind source control system

The invention relates to a wind source control system, in particular to a wind source control system capable of adjusting wind speed according to user information.

Under the influence of the greenhouse effect, global temperatures continue to increase. Especially for areas with a tropical monsoon climate like Taiwan, the temperature of the summer climate often exceeds 30 ° C or even 35 ° C. At this time, it is necessary to reduce the indoor temperature through the air conditioning system to reduce the high temperature in the summer and cause the human body to feel uncomfortable.

In the air blowing device of the conventional air conditioner, the air blowing direction is usually controlled by the blades that can swing back and forth, so that the air blowing device can uniformly blow the cold air to form a blowing range. However, since the air blowing direction and the air blowing range of the air blowing device are not immediately adjusted with the position of the user, the user's area is often not located within the air blowing range of the air blowing device. In this way, in addition to not allowing the user to effectively feel the air conditioning effect of the air conditioner, it will also cause waste of energy in the air supply device. Therefore, how to make the air conditioner effect of the air conditioner more direct and effective for the user to feel, and further avoid the waste of energy in the air conditioner, this will be one of the problems that the researcher should solve.

The invention provides a wind source control system and a wind source control method, so as to solve the problem that the air supply device maintains a constant speed and causes waste of energy regardless of whether the user's area is located within the air supply range of the air blowing device.

The wind source control system disclosed in one embodiment of the present invention comprises a wind source, an environment sensing module, a human body sensing module, a human-machine interaction module and a control module. The environment sensing module is used to sense the temperature and relative humidity of the environment. The human body sensing module is configured to sense a change in the distance between the person of the at least one user located in the environment and the at least one user and the wind source, and adjust the wind speed change of the wind source. The human-machine interaction module includes a communication device and a remote control device for providing an interactive message. The control module is configured to adjust the wind speed of the wind source according to the interactive information provided by the environment sensing module, the human body sensing module and the remote device communication device.

According to the wind source control system of the above embodiment, the control module can be flexibly transmitted through environmental information, personnel information, distance information and interactive information measured by the environment sensing module, the human body sensing module and the human-machine interaction module. Adjust the usage mode of the wind source. If the wind source is operating in comfort mode, the user can maintain similar comfort regardless of changes in environmental information and user location information. If the wind source is running in the energy-saving mode, when no one is used, the wind speed of the wind source can be reduced, and even more, the wind source can be turned off to reduce the energy loss. If the wind source is operating in a safe mode, when someone accidentally breaks in, the wind source will operate at the maximum wind speed, so as to achieve a small deterrent effect.

The above description of the present invention and the following description of the embodiments are intended to illustrate and explain the principles of the invention, and to provide a further explanation of the scope of the invention.

Please refer to Figure 1. 1 is a schematic plan view of a fan control system and a user according to a first embodiment of the present invention.

The fan control system 10 of the present embodiment includes a wind source 100, an environment sensing module 200, a human body sensing module 300, a human-machine interaction module 400, and a control module 500.

The wind source 100 is, for example, a ceiling fan, a ceiling fan, a fan, or an air conditioner. In the present embodiment, the wind source 100 is exemplified by a ceiling fan.

The environment sensing module 200 is configured to sense the temperature and relative humidity of an environment at an arbitrary time point. The comfortable wind speed S(T _i RH _j ) determined by the temperature and relative humidity at any point in time includes a temperature information and a relative humidity information.

The human body sensing module 300 is configured to sense a person information P of at least one user located in the environment and a wind speed change amount S(P _r ) to be adjusted by at least one distance change between the user and the wind source. The amount of change S(P _r ) may be positive or negative at least one wind speed difference.

The human-machine interaction module 400 includes a communication device 410 and a remote control device 420. The communication device 410 is, for example, a Bluetooth transceiver or a wireless network transceiver, and is electrically connected to the control module 500. The remote control device 420 is, for example, a remote controller coupled to the communication device 410. The remote control device 420 is configured for the user to operate and provides an interactive message to the communication device 410. In detail, the interactive information includes a general mode command, a comfort mode command, an energy saving mode command, a safety mode command, a smart mode command, and a wind speed setting command, so that the human interaction module 400 can control the wind source 100 in one The general mode, a comfort mode, an energy saving mode, a safe mode or a smart mode operates. Please refer to the description of each mode.

The control module 500 is configured to adjust the wind speed of the wind source 100 according to the information of the environment sensing module 200, the human body sensing module 300, and the communication device 410. If used in conjunction with an air conditioner, energy savings can be achieved.

When the user issues a general mode command through the remote control device 420, S=S(U), where S is the wind speed of the wind source and S(U) is the wind speed set by a user. That is to say, the wind speed S of the wind source 100 only changes with the user setting information S(U), and is not adjusted with the change of the distance information, the environmental information and the personnel information. Although the rotational speed of the wind source 100 is not adjusted according to the change of the distance information, the environmental information and the personnel information, the related information such as the distance information, the environmental information and the personnel information can still be transmitted to the remote control device 420 via the communication device 410.

Please refer to FIG. 2. FIG. 2 is a block diagram showing the operation of the fan control system of FIG. 1 in a comfortable mode. When the user wants to use the comfort mode, the wind speed of the wind source 100 can be adjusted to the required wind speed S (U), or not adjusted (ie S (U) = 0), and then the comfort mode is released through the remote control device 420. The command causes the wind source control system 10 to enter the comfort mode as shown in step S101. Next, the control module 500 determines the calculation formula of the wind speed of the wind source 100 by using the relationship S(U)=S(T ₀ RH ₀ ) as shown in step S102. If the relationship is established, as shown in step S103, S = S(T _i RH _j ) + S(P _r ) + S(F _s ). If the relationship is not true, then S=S(U)-S(T ₀ RH ₀ )+S(T _i RH _j )+S(P _r )+S(F _s ) as in step 104. Where S is the wind speed of the wind source, S (U) is the wind speed setting information of a user, S (T ₀ RH ₀ ) is a comfort wind mode determined by the temperature and humidity, S (T _i RH) _j ) is the comfortable wind speed determined by the temperature and humidity at any time point according to Fig. 3, S(P _r ) is the change of the wind speed according to the change of the distance between the user and the wind source according to Fig. 4A, and the wind speed change amount The difference between the user and the wind source may be measured by the human body sensing module 300, and the S(F _s ) is determined according to FIG. 5 The adjusted wind speed change amount, the wind speed change amount may be positive or negative at least one wind speed difference, which is set by the user and may be set differently for different users. That is to say, in the comfort mode, the wind speed S of the wind source 100 will set the wind speed S(U) with the user, and the comfortable wind speed S (T ₀ RH ₀ ) determined by the temperature and humidity of the current time point in the user setting comfort mode. The comfortable wind speed S (T _i RH _j ) determined by the temperature and humidity at any time point, the distance between the user and the wind source is changed to determine the wind speed change amount S(P _r ) to be adjusted, and the user feels at the moment. The wind speed change S(F _s ), which is cold or hot and needs to be adjusted, is adjusted to allow the user to maintain a comfortable wind speed.

Please refer to Figure 3. Figure 3 is a graph showing the relationship between environmental information (temperature, humidity) and wind speed of the wind source control system of Figure 1. In Fig. 3, rh ₁ ~rh ₅ represents humidity, and rh ₁ < rh ₂ < rh ₃ < rh ₄ < rh ₅ .

Please refer to Figure 3. The above information is further introduced. The user sets the comfort wind speed S (T ₀ RH ₀ ) determined by the temperature and humidity at the current time point of the comfort mode and the comfortable wind speed S (T _i RH _j determined by the temperature and relative humidity at any time point). ) can be determined through Figure 3. For example, under ambient conditions of temperature T _x and relative humidity rh ₃ , the determined comfortable wind speed is S(T _x RH ₃ ). That is, S(T ₀ RH ₀ ) and S(T _i RH _j ) can be obtained according to the temperature and humidity chart, that is, when the temperature is T _x and the relative humidity is rh ₃ , the comfortable wind speed S (T _x can be found by the chart _). RH ₃ ).

As shown in FIG. 3, at the same ambient temperature, the higher the relative humidity, the higher the comfortable wind speed corresponding to the wind source 100; in the same relative humidity, the higher the temperature, the comfortable wind speed corresponding to the wind source 100. The higher. Therefore, if the ambient relative humidity or temperature becomes high, the control module 500 can increase the wind speed of the wind source 100 according to the relationship between the temperature, the relative humidity and the wind speed shown in FIG. 3, so that the user can maintain the same comfort.

Please refer to FIG. 4A and FIG. 4B. 4A is a plan view of the change in distance information between the user of FIG. 1 and the wind source. 4B is a graph showing the relationship between the distance information and the wind speed when the distance information between the user and the wind source of FIG. 4A changes.

As shown in FIG. 4A and FIG. 4B, when the user shifts from the P ₀ position to the P ₁ or P ₃ position based on the P ₀ position, the distance information between the user and the wind source 100 is reduced. The control module 500 will reduce the wind speed of the wind source 100 to allow the user to maintain similar comfort. If the user shifts from the P ₀ position to the P ₂ position, the distance between the user and the wind source 100 increases, so the control module 500 increases the wind speed of the wind source 100 according to the relationship shown in FIG. 4B. As can be seen from the above, the change in the distance between the user and the wind source 100 is proportional to the amount of wind speed change S(P _r ) that is required to be adjusted accordingly.

In addition, if the distance between the user and the wind source 100 is less than a safety threshold, the control module controls the wind source to be turned off. The so-called safety threshold is, for example, 30 cm. The purpose is to prevent the user from inadvertently touching the wind source 100 when it is too close to the wind source 100, thereby causing damage to the user.

Please refer to Figure 5. FIG. 5 is a graph showing the relationship between the body information of the user of FIG. 1 and the wind speed of the wind source.

As shown in FIG. 5, the broken line indicates the possible comfortable wind speed change determined by the composite wind speed, such as the temperature and humidity of the wind source 100 and the change of the wind speed adjusted by the distance between the user and the wind source when the comfort mode is activated. situation. The thick solid line indicates that when the user feels hot after starting, the user sets the wind speed change of the wind source 100 that increases the amount of change of at least one wind speed. The thin solid line indicates that when the user feels cold after starting, the user sets the wind speed change of the wind source 100 that reduces the amount of change of at least one wind speed. That is to say, in the comfort mode, the user can fine tune the wind speed to meet the comfortable wind speed required by different users.

Please refer to Figure 6. 6 is a block diagram showing the operation of the fan control system of FIG. 1 in a power saving mode.

When the user wants to use the energy-saving mode, the wind speed of the wind source 100 can be adjusted to the required wind speed, and then the power-saving mode command is issued through the remote control device 420, so that the wind source control system 10 enters the energy-saving mode as shown in step S201. . Next, the control module 500 sequentially takes the relationship P=0 shown in step S202, and t>t ₁ and the relationship P=0, t>t ₂ and t ₂ >t ₁ shown in step S204. Determine the wind speed of the wind source 100. In detail, P=0, and t>t ₁ represents that the human body sensing module 300 senses that no user appears in the environment, and at least maintains a first time t ₁ . At this time, the control module 500 controls the wind speed S of the wind source 100 to be reduced to the minimum wind speed S _min , so that the energy consumption is reduced when no one is used. P=0, t>t ₂ and t ₂ >t ₁ represents that the human body sensing module 300 senses that no user is present in the environment and at least maintains a second time t ₂ greater than the first time. At this time, the control module 500 controls the wind speed S of the wind source 100 to be reduced to zero, so that the energy consumption is further reduced when it is not used for a long time.

Please refer to Figure 7. 7 is a block diagram showing the operation of the fan control system of FIG. 1 in a safe mode.

When the user wants to go out and wants to use the security mode for theft prevention, the wind source 100 can be turned off first, and then the safety mode command is issued through the remote control device 420, so that the wind source control system 10 enters the safe mode as shown in step S301. Next, the control module 500 determines the wind speed of the wind source 100 according to whether the relationship P=1 and t>t ₃ are established in step S302. In detail, P=1, and t>t ₃ represents that a user appears and continues for a third time t ₃ . At this speed control module controls the air source 500 will start and stop the _execution Winds S 100. S _max-ts-OFF at time intervals t _s, to start and stop by the sudden high wind speed and the maximum wind speed between the segment to frighten Illegal intruder. Furthermore, there are two possibilities for the above-mentioned users. The first one is the original user. Since the original user is familiar with the security mode, it will not be scared by the security mode and can directly The security mode is turned off by the remote control device 420. The second type is a user who is illegally intruded. Because the illegal intruder is not familiar with the security mode, it is easily frightened by the sudden high wind speed and the intermittent speed of the wind speed. Even worse, it may be mistaken that the original user still In the house, and rushed to escape.

Please refer to Figure 8. 8 is a block diagram showing the operation of the fan control system of FIG. 1 in a smart mode.

When the user wants to use the smart mode, the wind speed of the wind source 100 can be adjusted to the required wind speed, and then the smart mode command is issued through the remote control device 420, so that the wind source control system 10 enters the smart mode as shown in step S401. . Next, the control module 500 determines the control mode of the wind source control system 10 according to whether the relationship P=0 shown in step S402 and t>t ₁ is established. In detail, as shown in step S403, if P = 0, and t> t ₁ is not satisfied, it represents a human body sensing module 300 senses the user environment has occurred, and at least a first sustain times t ₁ . At this time, the control module 500 controls the wind source 100 to operate in the comfort mode. As shown in step S404, the relationship if P = 0, and t> t ₁ holds, the human body sensing module 300 representative of the sensed environment without the user appears, and maintained at least a first time t _1. At this time, the control module 500 controls the wind source 100 to operate in the energy saving mode first. Next, the control mode of the wind source control system 10 is determined according to the relationship P=0, t>t ₃ and whether t ₃ >t ₁ is established according to step S405. As shown in step S406, if the relationship P=0, t>t ₃ , and t ₃ >t _{1 is} established, the control module 500 controls the wind source 100 to operate in the safe mode.

According to the wind source control system of the above embodiment, the control module can be flexibly transmitted through environmental information, personnel information, distance information and interactive information measured by the environment sensing module, the human body sensing module and the human-machine interaction module. Adjust the usage mode of the wind source. If the wind source is operating in comfort mode, the user can maintain similar comfort regardless of changes in environmental information and user location information. If the wind source is running in the energy-saving mode, when no one is used, the wind speed of the wind source can be reduced, and even more, the wind source can be turned off to reduce the energy loss. If the wind source is operating in a safe mode, when someone accidentally breaks in, the wind source will operate at the maximum wind speed, so as to achieve a small deterrent effect.

Furthermore, if the wind source is operating in smart mode, the control module can operate the wind source in a comfortable, energy-saving and safe mode according to the relevant information.
