Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is suitable for application to an in-building central management device used in an intelligent building that enables central management of the inside of a building using a building management processor. It relates to an air conditioning control device.

[Conventional technology]

Multiple rooms in buildings such as offices and hotels are each equipped with an air conditioner to adjust the temperature and humidity within the room, but these air conditioners can only be activated or stopped by the person entering the room. In some cases, it is controlled manually by a person, and in other cases, it is automatically controlled based on commands from a management device installed within the facility.

In the former case, the user has to turn on and off the air conditioner each time he or she enters the room, which is troublesome. In the latter case, the air conditioner automatically starts and stops, which is more convenient than the former, but even in the latter case, it does not control the entry and exit of users, so It often happens that the air conditioner is activated even when no one is present.

Therefore, in the past, not only was it not possible to achieve energy saving in air conditioners, but also it was not possible to ensure the optimum environment for a particular room, and it was still difficult to say that the air conditioning services were sufficient.

[Problem that the invention seeks to solve]

In view of the above-mentioned conventional problems, it is an object of the present invention to provide an air conditioning control device that can determine whether a user enters or leaves a room and can optimally air condition a room where the user is present.

[Means for solving problems]

The present invention provides an ID card to be worn, which includes a storage section storing air conditioner management information of a user, and which transmits this air conditioner management information in response to a call signal;
It has a receiving section that receives air conditioner management information transmitted from the card, and a control section that transmits the call signal and controls the air conditioner based on the received air conditioner management information.

In the present invention, the control unit sends a calling signal,
When the air conditioner management information is not received, the air conditioner can be controlled so that the power consumption of the air conditioner is smaller than when the air conditioner management information is received.

In the present invention, when the control unit transmits a call signal and the air conditioner management information is not received, the air conditioner is stopped, and when the control unit transmits the call signal and the air conditioner management information is received, the air conditioner is activated. can be done.

[Effect]

In the present invention, an air conditioner is controlled based on air conditioner management information transmitted from an ID card in response to a call signal. Therefore, it is possible to determine whether or not a user has entered the room based on whether or not the air conditioner management information has been received, so the room can be optimally air-conditioned based on the user's air conditioner management information.
It is possible to improve air conditioning services.

In addition, if the air conditioner is controlled so that the power consumption of the air conditioner is smaller when the air conditioner management information is not received than when the air conditioner management information is received, Since the power consumption of the air conditioner can be reduced when there is no user in the room, energy saving of the air conditioner can be easily achieved.

Further, if the air conditioner management information is not received, the air conditioner is stopped, and if the call signal is transmitted and the air conditioner management information is received, the air conditioner is activated, and the air conditioner management information is received. Since the air conditioner does not operate when the user is not in the room, that is, when there is no user in the room, it is possible to start and stop the air conditioner without bothering the user, and it is also possible to easily achieve energy savings in the air conditioner. It is possible to improve air conditioning services.

There is an in-house central control system that allows commands to be given.

FIG. 1 shows an intelligent building 10 to which an embodiment of the present invention is applied.

In this Intelligent Building 10, users entering the building must use the ID card 12 shown in FIG. 2 in advance.
It is mandatory to enter the museum with a transponder card (TRC). The ID card 12 is made of a thin plate made of synthetic resin, for example, and has a photograph 14 of the user pasted on its surface, and a field 16 for displaying the name of the affiliation, etc. corresponding to the photograph 14. A clip 18 is provided on the back side of the ID card 12 so that the ID card 12 can be attached to a chest pocket or the like.

This ID card 12 has a built-in circuit shown in FIG.
The calculation unit 24 calculates the signal from the reception unit 26, determines whether it is a call signal for your own ID card 12, and sends the signal to the notification unit 28 and the transmission unit when necessary. 30 are activated to notify and transmit information to the outside.

In addition, in this ID card 12, the calculation section 2 is
The power switching section 20 operates only when the main circuit of No. 4 is not energized and a call signal from the outside is received by the receiving section 26, and the main circuit such as the arithmetic section 24 is operated by the power supply section 22. By doing so, the life of the power supply unit 22 is extended.

As an example, the power supply unit 22 can be a thin card-shaped battery having a structure in which two conductive plastic films are coated with manganese dioxide powder on one side and zinc powder on the other, stacked on top of each other with a non-woven fabric sandwiched between them. Further, as an example, the circuits such as the calculation section 24, the reception section 26, the notification section 28, the transmission section 30, etc. can be configured with a thin IC device, and the ID card 1
2 can be an ID card in which the IC device is built into a thin plastic card.

The transmitter 30 is a plurality of ID cards 12 that are manufactured.
The notifying unit 28 can transmit a signal to identify itself, such as a different frequency for each unit, and the notifying unit 28
Different types of notification signals can be emitted depending on different types of received signals received at the terminal. for example
When transmitting a call signal to a user in possession of the ID card 12, the tone, frequency, signal cycle, etc. of the signal will be changed depending on the type of call, such as a call signal to a specific room or a call signal to an in-house telephone. What is necessary is to control the output signal to the notification section 28 so that the notification signal is emitted as follows.

In addition to the function of transmitting a code signal to identify the ID card holder, this ID card 12 has the following functions:
Furthermore, it is possible to transmit an air conditioning control code signal encoded with air conditioning device management information for controlling the air conditioner (air conditioner) in the room to a preset air conditioning state. The air conditioning control code signal is set by a setting section 32 shown in FIG.

The setting section 32 is provided with setting keys for setting the indoor temperature and humidity to the temperature and humidity desired by the card holder, and by operating these keys, the air conditioner management information of temperature and humidity can be changed to any desired value. Can be set to a value.

The air conditioning control code signal may be transmitted following the above-mentioned code signal for owner identification, or a part of the code signal for owner identification may include code content that can be distinguished from this code signal. It may be multiplexed.

Therefore, in this case, the code signal includes the owner identification code and the air conditioning control code.

FIG. 1 shows an example of an air conditioning control device 10 according to the present invention, and shows each room 2A, 2B, . . . in a building.
have antennas (bar antenna, etc.) 4A and 4, respectively.
B,... are attached to the ceiling etc., and room 2A,
The code signal transmitted from the ID card 12 owned by the person entering the room 2B,... is sent to the antennas 4A, 4B,
...received by radio equipment (TRT) 32A, 32B,
... and these TRT32A, 32B, ...
The code signals transmitted from the local radio controllers (LRCs) 34A, 34B, ... are sent to the central radio controllers via the local area network (LAN) 36. (CRC) 38 is received.

The code signal received by the CRC 38 is sent to a central control processor (GP) 40 in the building, where the contents of the code signal are determined, and if necessary, a display 42 is sent.
Alternatively, the data contents and the air conditioning status of the room where the code signal is sent are supplied to the printer 44,
Persons entering the room are displayed or printed out.

Furthermore, a transmitting device (not shown) is installed in each room 2A, 2B, . . . in the building. These transmitting devices are radios (TRT) 32A, 32B,
... and always sends out a calling signal for the ID card 12. As a result, when a user enters the room, the user's ID card 12
The receiving section 26 receives the calling signal, and the transmitting section 30 receives the calling signal.
A code signal containing the above-mentioned air conditioner management information is transmitted from the air conditioner. This signal is sent to antennas 4A, 4B,
By receiving the code signals and sending them to the processor (GP) 40, the processor (GP) 40 can determine whether a user has entered the room and can also determine the number of users in the room based on the number of received code signals. can. Similarly, the processor (GP) 40 determines that the user is not in the room when no code signal is received.

The CRC 38 receives data from a distributed processing processor (DDP) 46, is connected to an electronic exchange (EPBX) 48, and controls external lines as necessary.

In case of emergency, GP40 or
This is to provide a function that can secure a specific telephone line based on the commands of the DDP 46.

In the GP 40 that has received the code signal, data for air conditioning control for the specific room that received the code signal is sent to the air conditioning control unit (building control remote station, SRS) 50 via the CRC 38.
A, 50B, . . .

SRS50A, 50 that received air conditioning control data
In B,..., in order to control the air conditioning state corresponding to the control data, an air conditioner (AHL) 52 and a heater control system 54A, which is provided corresponding to each room, are installed.
54B, . . . and blowers 56A, 56B, . . . are individually and independently controlled.

The AHU 52 controls fan air volume, motor damper opening (air supply, ventilation), and coil valve opening. 58 is a fan air volume control motor, and 60 is a damper opening control motor.

A temperature and humidity sensor 64 is arranged in each room,
The respective sensor outputs are sent to the DP 40 via the SRSs 50A, 50B, . . . , and the temperature and humidity data of each room is input. As a result, the indoor temperature and humidity data before air conditioning and the temperature and humidity data after air conditioning are used as data for air conditioning control.

Now, when controlling the air conditioning of each room 2A, 2B,... by the code signal from the ID card 12,
The following control modes are possible.

First, when no one is present, the AHU 52 is completely stopped, and when a code signal from the ID card 12 is received, it is determined that there is a user in the room.
A mode in which the AHU 52 is activated and the air conditioning of the room is controlled to the optimum value based on the air conditioner management information included in the received code signal.

In this case, energy saving of the AHU 52 can be achieved. In addition, since such control controls the transmission of control commands from the GP 40 depending on whether or not a code signal is received, the control program is relatively simple.

The second method is to set the air conditioning temperature to a higher temperature in the summer and lower in the winter when no one is present, in other words to reduce the power consumption of the air conditioner, and to control the air conditioning to the optimum state from the time the person enters the room.

In this case as well, it is easy to execute because the above-mentioned values are input in advance as the initial conditions for air conditioning control, and a control program is created so that the optimum value is obtained when the code signal is received. Furthermore, energy savings can be achieved compared to when the AHU 52 is operated in its normal state regardless of the presence or absence of people.

Thirdly, in addition to the first or second aspect described above,
A mode in which the air conditioner management information is set in advance to the temperature and humidity desired by the user, and after receiving a code signal, the temperature and humidity are controlled to the desired temperature and humidity of the user who enters the room based on this air conditioner management information.

In this case, it is possible to achieve an air conditioning condition that best suits the occupant. For example, it is most suitable for a boardroom where there are not many people going in and out and the people who enter the room are elderly. This type of air conditioning control uses the contents of the air conditioning control code signal as described above.
40 and send the corresponding control data to SRS5.
It is sufficient to send it to 0A, 50B, . . .

Fourth, in the case of the first and second control modes described above, the number of people entering the room is predicted and the optimum air conditioning state is controlled accordingly.

This case is suitable for use when the number of people entering the room is not constant, such as in a conference room. it is,
If you set the optimal air conditioning conditions by anticipating a certain number of people entering the room, if the number of people entering the room is significantly less than this or, conversely, more than this, the room will be controlled to the optimal air conditioning condition. This is because it becomes impossible to do so.

FIG. 4 is a control flowchart showing an example of the third mode among the air conditioning control modes described above.

When a user with an ID card 12 enters a room, for example 2A, and the GP 40 receives a code signal from the ID card 12, the air conditioning control program is started by a reception interrupt, and in step 70, the air conditioning control code signal is sent. Accepted. That is, the individual's desired room temperature data is input into the GP 40 by the air conditioning control code signal.

Thereafter, in step 72, the sensor output from the temperature/humidity sensor 64 of the room 2A is
Control data for the AHU 52 and the blower 56A are determined and determined by the GP 40 based on the air conditioning conditions.

The determined control data is sent to SRS5 in step 74.
It is sent to the AHU 52 and the blower 56 via 0A.

The room temperature of the room 2A is controlled based on this control data, and at this time, it is checked whether the desired room temperature in step 76 is higher than the set temperature based on the feedback of the sensor output described above, and if it is lower than the set temperature, step 76 is performed. At 78, the blower 56A reduces the amount of air blown while ensuring the necessary ventilation amount. At the same time, the rotation speed of the fan provided in the AHU 52 and the opening degree of the motor damper are also controlled.

Then, in step 80, the control result of step 78 is determined. To this end, after a certain period of time has elapsed, it is determined whether the room temperature has reached the desired value based on the above-mentioned sensor output. If the room temperature is the desired room temperature, the air conditioning control operation is terminated; if not, step 82 is performed. Then, the temperature is heated using the heater 54A, and then the process returns to step 80, and the same control operation is repeated.

On the other hand, if it is determined in step 76 that the temperature is higher than the set temperature, the process moves to step 88, where the blower 56A increases the air volume and
The damper openings of the fan and motor in the AHU 52 are also controlled at the same time.

The control result is checked in step 90.
That is, it is checked whether the room temperature has reached the set temperature based on the sensor output, and if it is below the set temperature, the process returns to step 90, and when the set temperature has been reached, the process moves to step 94, where the air volume is maintained as it is. After a certain period of time has elapsed in step 96, it is determined whether the room temperature has reached the desired temperature, and if the desired temperature has been reached, the control operation ends.

However, if the desired temperature is not reached after a certain period of time, the cooling coil valve provided in the AHU 52 is opened in step 98 to increase the flow rate of chilled water, and then in step 100, the room temperature is checked after a certain period of time has elapsed. If the desired temperature is reached, the control operation ends, but if not, step 102
The ID card holder is notified by means such as a buzzer that the room temperature cannot be lowered any further.

Through the control flow described above, the air conditioning state of the room 2A is automatically controlled to the air conditioning state desired by the user who has entered the room 2A.

〔Effect of the invention〕

As explained above, in the present invention, the air conditioner is controlled based on the air conditioner management information transmitted from the ID card in response to the call signal, so the room is optimized based on the user's air conditioner management information. It has the excellent effect of improving air conditioning services.
