Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is a blind control mechanism provided as part of a building management system for maintaining a comfortable internal environment of high-rise buildings and other buildings. This relates to a blind control mechanism that automatically changes the

[Conventional technology]

Blinds are generally opened/closed and their angles adjusted by pulling a string, but some blinds are opened/closed and their angles adjusted electrically using a drive device. Further, a blind control device is also known that controls such a drive device to automatically open/close the blind and adjust the angle at a predetermined time. Such a blind control device automatically operates, for example, to close the blinds during bright daytime hours and open them when it gets dark in the evening.

[Problem to be solved by the invention]

If the blinds are opened and closed at predetermined times like a conventional blind control device, the incident light can be adjusted in response to changes in sunlight throughout the day. However, sunlight changes depending on the season, or more precisely, from day to day, so after a few days, the times at which the blinds are opened and closed no longer correspond to daily changes in sunlight. Therefore, in this case, there is an inconvenience in that a person has to input the opening/closing times of the blinds into the control device again.

Also, even if you open and close the blinds in response to changes in sunlight each day, the amount of sunlight naturally differs between sunny and cloudy days, so for example, even if it is daytime, when it is cloudy, the blinds should be closed. Sometimes it's better to open it. Furthermore, even in the same building, depending on the direction of the windows and what floor the room is on, external factors such as being in the shadow of the next building or sunlight reflecting from the windows of the next building can affect the environment. Depending on the situation, it may be necessary to open and close the blinds.

In such a case, the conventional blind system '#B device
People had to open and close the blinds themselves depending on the weather and external factors.

The present invention has been made based on the above circumstances, and aims to provide a blind adjustment mechanism that automatically adjusts the amount of light incident through a window in response to changes in sunlight due to weather and external factors in the surroundings. This is the purpose.

〔Example〕

One embodiment will be described below with reference to the drawings. The attached drawing is a configuration diagram of a blind control mechanism that is an embodiment of the present invention.

The blind control mechanism shown in the figure includes a calendar and clock device 2 as clock means, a storage device 4 as storage means,
It is composed of a weather information input device 6 and a temperature sensor 8 that collect information for the day, a calculation device 10 that is a calculation means, and a blind drive device 12 that drives the blinds.

The calendar and clock device 2 inputs the time and date to an arithmetic device 10, which will be described later, with the same high precision as a normal digital clock. The storage device 4 stores data regarding the incident angle of sunlight and the influence of sunlight due to surrounding external factors.

These data are calculated by calculating the position of the sun in the sky from sunrise to sunset, which changes depending on the season, based on weather data. This is obtained by calculating the incident angle, the time period when the neighboring building is in the shade, and the time when the reflected light from the neighboring building's window is incident. The weather information input device 6 is configured by installing several sky illumination meters on the roof of a building, for example, to collect information regarding the weather of the day and input it to the arithmetic device 10. The temperature sensor 8 uses a temperature sensor of an air conditioner provided in a general building management system to sense the temperature in the center of the room and near the windows, and supplies the information to the arithmetic unit 10.

The computing device 10 includes a calendar and clock device 2, and a storage device 4.
After receiving information from the weather information input device 6 and temperature sensor 8 and performing predetermined calculations, a drive signal is sent to the blind drive device! Supply to f12. The blind driving device 12 uses an electric motor (not shown) to change the angle of each blade of the blind while keeping them parallel. At this time, for example, by making the rotation angle of the motor correspond to the change in the angle of the blind blades, it is possible to not only open and close the blinds, but also adjust the blinds to any angle to let in the appropriate light. .

In a normal operating state, the calculation device 10 calculates data stored in advance in the storage device 4 and signals from the calendar and clock device 2, and sends a predetermined drive signal to the blind drive device 12 according to the data stored in the storage device 4. supply to. This storage device 4 not only stores changes in sunlight conditions during the day and changes in sunlight conditions throughout the year, but also stores information on times when neighboring buildings are in the shade and reflected light from the windows of neighboring buildings. External factors such as time of day are memorized. Therefore, even if the sunlight conditions change depending on the season, the blinds can be opened/closed and the angle adjusted according to the changes in the sunlight conditions.

In addition, it is possible to perform detailed control tailored to the unique situation of a room, such as closing the blinds during times when strong reflected light is coming from a neighboring building, which greatly reduces the need for human intervention.

In addition to such control, the weather information input device 6 is activated to input information regarding the weather of the day to the calculation device 10, and the angle of the blind is adjusted according to the information, thereby making adjustments based on time and date. can be corrected. This weather information input device 6 may be configured such that a person directly inputs the weather information of the day, or a sky illuminance meter is provided on the roof of the building or in each room, and the output is sent to the computing device 1.
By providing the weather information input device 6, which may be input to 0, it is possible to automatically perform control such as opening the blinds on a cloudy day even during the day.

By the way, for example, in high-rise buildings where windows cannot be opened or closed, air conditioning equipment is used to keep the temperature inside uniform and constant, but if the sun's rays are strong, The temperature in the area near the window may be higher than the temperature in the area near the window.

In such a case, the temperature difference between the center of the room and the window is further measured based on the temperature information from the temperature sensor 8 for the air conditioning equipment, and if the temperature difference exceeds a certain temperature,
The arithmetic unit 10 determines that this temperature difference is due to sunlight, and adjusts the angle of the blind to automatically block sunlight coming in through the window. Therefore, by linking the temperature sensor for air conditioning equipment with the blind control mechanism of this embodiment, it is possible to supplement the function of the air conditioning equipment to maintain a uniform temperature throughout the room. Incidentally, the temperature sensor 8 may be provided separately instead of being used together with one for air conditioning equipment.

〔Effect of the invention〕

As explained above, according to the present invention, by storing annual sunshine information calculated in advance and external factors such as reflection of sunlight from neighboring buildings, the sunshine state changes depending on the season. This eliminates the hassle of having to re-enter that information, and also prevents unpleasant strong sunlight from reflecting off neighboring buildings.

Furthermore, according to the present invention, in addition to the above-mentioned effects, the angle of the blind can be automatically adjusted in response to changes in sunlight due to the weather, which eliminates the hassle of having to manually adjust the blinds according to changes in the weather. It can be resolved.

Furthermore, according to the present invention, in addition to the above effects, the angle of the blind can be automatically adjusted according to the temperature difference between the center of the room and the window, so that the temperature inside the room can be made uniform. A blind control mechanism can be provided that assists in temperature control of air conditioning equipment.
