DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention receives a set value from a higher-level device such as an air-conditioning monitoring device and a set value from a wireless transmitter, and fetches the set value as a new set value with a later priority. The present invention relates to a wireless air-conditioning control system including an air-conditioning control device that controls the operation of an air conditioner so that a value matches a detected value.

[0002]

2. Description of the Related Art As a wireless air-conditioning control system of this type, the present applicant has considered a system whose main part is shown in FIG. In the figure, 1 is an air conditioning monitoring device, 2
Is an air-conditioning control device, 3 is an air conditioner, 4 is a receiver provided on the ceiling of a room that is air-conditioned by the air conditioner 3, and 5 is a portable wireless device that is placed in a room that is air-conditioned by the air conditioner 3. It is a remote control.

[0005] The wireless remote controller 5 is of an infrared wireless communication system, and is a one-way communication only for transmission to the receiver 4 for the following reasons. I want to be a small object that can be held and operated (two-way communication: larger). I want to eliminate restrictions on the location (two-way communication:
It is restricted to a place where it can communicate reliably.) I want to use a simple dry battery as the power source (two-way communication: dry batteries are exchanged too often because communication is always possible). I want to be inexpensive with the minimum required functions (two-way communication: expensive).

The wireless remote controller 5 includes a temperature sensor T
1, a room temperature measured by the temperature sensor T1 is displayed on a display unit (liquid crystal) 5-1. The wireless remote controller 5 is provided with room temperature setting keys 5-2U and 5-2D. FIG.
(A) shows the measured value T _{Rp v} of the room temperature on the display unit 5-1.
Shows the display status of.

[0005] That is, in the wireless remote controller 5, usually, only the measured value T _Rpv of the room temperature is displayed on the display unit 5-1, room temperature setting key 5-2U, only measured values T _Rpv when operating the 5-2D Instead, the set value T _Rsp is displayed. Note that it is displayed in the measured value T _{Rp v} of the room temperature is informed by the appearance of a triangle mark M1. The fact that the set value T _Rsp is being displayed is notified by the appearance of the triangle mark M2.

Now, it is assumed that the display (room temperature display) of the measured value T _Rpv of the room temperature on the display unit 5-1 of the wireless remote controller 5 is 25 ° C. Further, in the air-conditioning control device 2, it is assumed that the control is stable, the set value T _sp is 25 ° C., and the detected value T _pv is 25 ° C. (point t ₁ shown in FIG. 8).
From such a state, in the wireless remote control 5,
When the room temperature setting key 5-2U is pressed once (t shown in FIG. 8).
_As shown in FIG. 7B, the triangular mark M1 disappears and the triangular mark M2 appears. As a result, the display is switched from the room temperature display to the setting display, and the set value T _Rsp = 25 ° C.
(Point t ₂ shown in FIG. 8).

When the room temperature setting key 5-2U is further pressed twice (point t ₃ shown in FIG. 8), the setting display becomes 27 ° C. (FIG. 7)
(C)). When a predetermined time has elapsed in this state, the set value T
_Assuming that _Rsp has been determined, the determined set value T _Rsp
Is transmitted to the receiver 4 side.

The receiver 4 receives the changed value α = + 2 ° C. from the wireless remote controller 5 and sends it to the air conditioning controller 2. As a result, the air-conditioning control device 2 adds the amount of change from the wireless remote controller 5 to the currently fetched set value _Tsp in the direction of the change, that is, if the change value α is +, α is added to the currently fetched set value _Tsp . adds, changes value α is - if subtracts α from a set value T _sp that incorporates current to the set value T _Rsp from the wireless remote controller 5. In this case, α = + 2 ° C. is added to the set value T _sp = 25 ° C., and the set value T _Rsp from the wireless remote controller 5 is set to 27 ° C.

[0009] Then, the air conditioning control device 2 takes the set value T _Rsp from the wireless remote controller 5 as a new set value T _sp, the air conditioner 3 so as this setting value T _sp and the detected value T _pv matches Control the operation of That is, the set value T _sp is changed to 27 ° C., and the current detected value T _pv = 25 ° C. is changed to 2 ° C.
The operation of the air conditioner 3 is controlled to be 7 ° C. (t ₃ to t ₆ shown in FIG. 8).

On the other hand, the wireless remote controller 5 is, sending the determined set value T _Rsp to the receiver 4 side, returns to the original room temperature display (t ₄ points shown in FIG. 8). That is, FIG.
As shown in the figure, the triangle mark M2 disappears and the triangle mark M1
Appears, and the detected value T _Rpv at that time is displayed as 25 ° C. At this time, the wireless remote controller 5 stores the set value T _Rsp = 27 ° C. transmitted to the receiver 4 for T seconds. Thereafter, the operation control of the air conditioner 3 by the air conditioning control device 2
The room temperature display on the display unit 5-1 is 27 ° C. (point t ₆ shown in FIG. 8, FIG. 7E).

[0011]

However, in such a wireless air-conditioning control system, the air-conditioning control device 2
During operation control of the air conditioner 3, that is, while controlling the operation of the air conditioner 3 so that the set value _Tsp and the detection value _Tpv match, the change value transmitted from the wireless remote controller 5 When α is received, the set value T _sp may not be set to a value desired by the operator of the wireless remote controller 5.
That is, the set value T _sp may become a value unexpected by the operator of the wireless remote controller 5.

For example, suppose that the changed value α = −4 ° C. is transmitted from the wireless remote controller 5 to the receiver 4 at time t ₁₁ shown in FIG. In this case, the air-conditioning control device 2 subtracts the changed value α = −4 ° C. from the currently acquired set value T _sp = 30 ° C., and sets the set value T _Rsp from the wireless remote controller 5.
_Is set to 26 ° C., and the set value T _Rsp = 26 ° C. is taken in as a new set value T _sp , and the operation of the air conditioner 3 is performed so that the set value T _sp = 26 ° C. matches the detected value T _pv = 30 ° C. Control.

[0013] During operation control of the air conditioner 3 according to the air conditioning control device 2, in t ₁₄ points older than T seconds after sending to the receiver 4 side changes value alpha = -4 ° C. at t ₁₁ points, at room temperature It is assumed that the setting key 5-2D is pressed once. Then, the measured value T _Rpv = 29 ° C. of the room temperature at that time is displayed as the set value T _{Rsp on} the display unit 5-1 of the wireless remote controller 5. In this case, the set value T _sp which is incorporated in the air conditioning control device 2 is 26 ° C., between the T _sp of actually used in the setting value T _Rsp and the air conditioning control device 2 to be displayed in the wireless remote control 5 Mismatch.

[0014] Here, in order to decrease the set value T _Rsp, press 4 times at room temperature setting key 5-2D (t ₁₅ points shown in FIG. 8),
The setting display on the display unit 5-1 is 25 ° C. When a predetermined time has elapsed in this state, the changed value α = −4 ° C. is transmitted to the receiver 4 assuming that the set value T _Rsp has been determined. As a result, in the air-conditioning control device 2, α = −4 ° C. is subtracted from the currently acquired set value T _sp = 26 ° C.
_Let 2 ° C be the set value T _Rsp from the wireless remote control 5,
This set value T _Rsp = 22 ° C. is taken in as a new set value T _sp . In this case, the value desired by the operator of the wireless remote controller 5 is 25 ° C., but the new set value T _sp taken into the air-conditioning control device 2 is 22 ° C., which is lower than the value desired by the operator of the wireless remote controller 5. The set value T _sp is lowered by as much as 3 ° C., and the room temperature is lowered more than necessary, resulting in energy loss.

Further, in this wireless air-conditioning control system, the display unit 5-1 and the temperature sensor T1 are required in the wireless remote controller 5, and the wireless remote controller 5 has a small size.
Prevents weight reduction and cost reduction. In addition, power consumption increases, and a large capacity battery must be used, which also hinders miniaturization.

The present invention has been made to solve such a problem, and an object of the present invention is to set a desired value to a value desired by an operator of a wireless transmitter, that is, to set an unexpected value. It is an object of the present invention to provide a wireless air-conditioning control system that can avoid the situation of becoming a wireless transmitter and can promote reduction in size, weight, and cost of a wireless transmitter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments. [First Embodiment] FIG. 2 is a front view of a wireless remote controller used in a wireless air-conditioning control system according to the present invention. That is, in this embodiment, a wireless remote controller 6 as shown in FIG. 2 is used instead of the wireless remote controller 5 shown in FIG. In FIG. 2, 6-1 is an air conditioner start / stop key, 6-2U and 6-2D are room temperature setting keys, 6-3.
A, 6-3H, 6-3M, 6-3L are air volume setting keys, 6
-4 is a transmission unit. This wireless remote controller 6 has no display unit and no temperature sensor. Note that the wireless remote controller 6 is of an infrared wireless communication system, similar to the conventional wireless remote controller 5, and is one-way communication only for transmission to the receiver 4.

Now, in the air conditioning control system using the wireless remote controller 6, it is assumed that the control is stable, the set value T _sp is 25 ° C., and the detected value T _pv is 25 ° C. (FIG. 1)
T ₁ point) shown in. From this state, the wireless remote control 6, pressing once the room temperature setting key 6-2U (t ₂ points shown in FIG. 1), is + 1 ° C. as a change value α is transmitted to the receiver 4 side.

The receiver 4 receives the changed value α = + 1 ° C. from the wireless remote controller 6 and sends it to the air conditioning controller 2. As a result, the air-conditioning control device 2 adds the changed value α = + 1 ° C. to the currently acquired set value T _sp = 25 ° C. to _obtain the set value T _Rsp from the wireless remote controller 6, and this set value T _Rsp = 26 ° C. As a new set value T _sp .

If the room temperature setting key 6-2U is pressed again on the wireless remote controller 6 before T seconds have elapsed since the previous transmission (point t ₃ shown in FIG. 1), the changed value α is set to +
1 ° C. is transmitted to the receiver 4 side. As a result, the air-conditioning control device 2 adds the changed value α = + 1 ° C. to the currently acquired set value T _sp = 26 ° C. to _obtain the set value T _Rsp from the wireless remote controller 6, and this set value T _Rsp = 27 ° C. As a new set value T _sp .

If the next change value α is not transmitted from the wireless remote controller 6 within T seconds after the new set value T _sp = 27 ° C. is acquired, the set value T _sp
= 27 ° C. and the detected value T _pv = 25 ° C. begin to control the operation of the air conditioner 3 (point t ₄ shown in FIG. 1). At this time, the air conditioning control device 2 sends a command to the receiver 4 and
Is displayed to indicate that the operation is being controlled.

In this embodiment, a light emitting diode (not shown) is provided in the receiver 4 toward the indoor side. The light emitting diode is lit green when the system is operating, and is turned off when the system is stopped. In addition, wireless remote control 6
When the data is received, the light emitting diode is illuminated in red for one second. Further, while the air-conditioning control device 2 is controlling the operation of the air conditioner 3, the operator of the wireless remote controller 6 is informed that the control is being performed by lighting the light emitting diodes. That is, when the detection value T _pv is being controlled to increase (room temperature rise), the lighting state of the light emitting diode is controlled as shown in FIG. When the detection value T _pv is being controlled to decrease (room temperature decrease), the lighting state of the light emitting diode is controlled as shown in FIG.

[0026] During operation control of the air conditioner 3 according to the air conditioning control device 2, the _five points t, and press once the temperature setting key 6-2U. Then, + 1 ° C. is transmitted from the wireless remote controller 6 to the receiver 4 as the changed value α. The receiver 4 changes the value α = + 1 from the wireless remote controller 6
C is received and sent to the air conditioning controller 2. Here, in the air-conditioning control device 2, the change value α from the wireless remote controller 6 is used.
Allowing changes settings T _sp-based, although the operator of the wireless remote control 6 hopes to early T _pv = 27 ° C. from the delay in the control, i.e., T _sp is 27 ° C.
Although it is considered that the temperature may be kept as it is, T _sp = 28 ° C., the room temperature rises more than necessary, and energy is lost.

Therefore, in this embodiment, while the operation of the air conditioner 3 is controlled in the air conditioning control device 2 so that the set value T _sp and the detected value T _pv match, the wireless remote control 6 The transmitted change value α is not accepted. That is, in this embodiment, the change of the set value _Tsp from the wireless remote controller 6 is refused during the operation control of the air conditioner 3 in the air conditioning control device 2. Therefore, in this embodiment, the change value α is transmitted from the wireless remote controller 6 at the point t ₅ shown in FIG.
= + 1 ° C, this wireless remote controller 6
Change of the set value T _sp from the air conditioning control device 2 is rejected,
The set value T _sp in the air conditioning control device 2 is maintained at 27 ° C. (t ₅ to t ₇ shown in FIG. 1), and no energy loss occurs.

It is now _{assumed that} 29 ° C. is given as the set value T _Bsp from the air conditioning monitoring device 1 at a point t ₈ shown in FIG. In this case, the air conditioning controller 2 fetches the set value T _Bsp from air conditioning monitoring device 1 as a new set value T _sp, the air conditioner 3 so as this setting value T _sp and the detected value T _pv matches
Control the operation of That is, the set value T _sp is changed to 29 ° C., and the operation of the air conditioner 3 is controlled such that the current detected value T _pv = 27 ° C. is set to 29 ° C. (t ₈ to t ₁₀ shown in FIG. 1).
Even during the operation control of the air conditioner 3, the air conditioning control device 2
Sends a command to the receiver 4 to display an indication that the operation of the air conditioner 3 is being controlled. Also in this case, the change of the set value _Tsp from the wireless remote controller 6 is rejected by the air conditioning control device 2.

Further, in this embodiment, during the operation control of the air conditioner 3, the change of the set value T _sp from the wireless remote controller 6 is rejected by the air conditioner controller 2 regardless of the sign of the change value α. That is, when the changed value α = + 1 ° C. is transmitted twice from the wireless remote controller 6 at the point t ₁₃ shown in FIG. 1, the changing direction of the set value _Tsp is the increasing direction, and the control direction (detection direction) at that time is changed. Although the direction is opposite to the direction in which the value T _pv is decreased), that is, the direction in which energy loss does not occur, in order to avoid that the set value T _sp becomes an unexpected value of the operator of the wireless remote controller 6 ( In this case, T _pv
(= 29 ° C., the desired value is 31 ° C.), and the change of the set value T _sp from the wireless remote controller 6 is rejected by the air-conditioning control device 2.

[Second Embodiment] In the first embodiment, while the operation of the air conditioner 3 is controlled in the air-conditioning control device 2 so that the set value _Tsp and the detected value _Tpv coincide with each other, The change value α transmitted from the wireless remote controller 6 is not accepted. That is, during the operation control of the air conditioner 3, the change of the set value _Tsp from the wireless remote controller 6 is rejected regardless of the sign of the change value α.

[0031] In contrast, in the second embodiment, the change of the set value T _sp to the control direction rejected, the control direction is changed settings T _sp in the reverse direction to allow. That is, when the change value α = + 1 ° C. is transmitted from the wireless remote controller 6 at the point t ₅ shown in FIG. 4, the change direction of the set value _Tsp is a direction of increasing, and the control direction (detection value T _pv Change value α = + 1
The change of the set value _Tsp by ° C is rejected.

On the other hand, when the change value α = + 1 ° C. is transmitted twice from the wireless remote controller 6 at the time t ₁₃ shown in FIG. 4, the change direction of the set value T _sp is a direction in which the set value T _sp is increased. (The direction in which the detected value T _pv is lowered) is opposite to the control direction, so that the change of the set value T _sp by the change value α = + 2 ° C. is permitted. As a result, the set value _Tsp in the air conditioning control device 2 becomes 27 ° C., that is, the desired value of the operator of the wireless remote controller 6 (T _pv = 29 in this case).
The desired value slightly deviates from 31 ° C., but no energy loss occurs.

Here, in the first embodiment, when the change value α is transmitted from the block B1 during the operation control of the air conditioner 3, in response to YES in the function block 203, the current set value T _sp The operation control of the air conditioner 3 based on is continued (functional blocks 201 and 202). That is, the air conditioner 3
When the change value α is transmitted from the block B1 during the operation control of, the change of the set value _Tsp based on the change value α is refused, and the operation control of the air conditioner 3 based on the current set value _Tsp is continued. I do.

On the other hand, in the second embodiment, the air conditioner 3

In the above-described embodiment, the temperature of the indoor environment to be air-conditioned is set to a temperature. However, the temperature is not limited to the temperature, and may be humidity, CO ₂ concentration, or the like. In addition, although the wireless remote controller 6 uses the infrared wireless communication system, it is not limited to the infrared system. Also,
Although the data from the receiver 4 to the air conditioning control device 2 is transmitted by wire, the data may be transmitted wirelessly.
