Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an in-building calling device that can accurately call visitors to a building.

[Background technology and matters to be solved]

When calling a specific visitor in a building such as an office building, it is necessary to broadcast the message using speakers or the like in all areas where the visitor is expected to be present. This creates noise for people other than the visitors who are called, and may interfere with work.

For this reason, some buildings do not allow internal calls.

Furthermore, even if a call is made to a resident from outside, if the resident is away from his or her desk, it is impossible to reliably get the call to the resident, which may impede smooth office work.

The present invention has been made in consideration of the above-mentioned facts, and an object of the present invention is to obtain an in-building paging device that can directly send a paging signal to a visitor.

[Summary and operation of the invention]

The in-building paging device according to the present invention includes a transponder carried by a visitor, which is equipped with a transmitting section and a receiving section that transmits a signal for identifying the user, and a notifying section based on the received information, and a transponder installed at multiple locations in the building. receiving means for receiving the transmission signals of the transponders; general calculation means for ascertaining the location of each transponder based on the signals from these receiving means and supplying a calling command; It has a plurality of transmitting means for transmitting a calling signal to the transponder from the vicinity of the transponder.

Therefore, when calling a visitor, the transmitting means that receives the signal from the general calculation means directly transmits the calling signal to the transponder that received the calling command. Therefore, a visitor with a transponder can sense a call to himself or herself, and can make a direct and reliable call inside the building.

[Embodiments of the invention]

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

In this intelligent building IO, visitors are asked to
It is mandatory to enter the museum with the ID card 12 shown in the figure. The ID card 12 is made of a thin plate made of synthetic resin, for example, and has a photograph 14 of the visitor affixed to its surface, and a field 16 for displaying the name of the affiliation, etc. corresponding to the photograph 14. Also this ID card 12
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 breast pocket or the like.

This ID card 12 has a built-in circuit shown in FIG.
2 to all circuits such as the arithmetic unit 24, and this arithmetic unit 2
4, the signal from the receiving section 26 is calculated and it is determined whether it is a calling signal for the own [0 card 12], and when necessary, the notifying section 28 and the transmitting section 30 are activated to send a signal to the outside respectively. Announcements and transmissions are being made.

Furthermore, in this ID card 12, power is not supplied to the main circuit of the calculation section 24 at all times, and only when the receiving section 26 receives a call signal from the outside, the power switching section 24
By operating the power supply unit 22 to operate the main circuit of the calculation unit 24, the life of the power supply unit 22 can be extended.

- As an example, this power supply section 22 can use a thin card-shaped battery made of two conductive plastic films coated with manganese dioxide powder on one side and zinc powder on the other, stacked one on top of the other with a non-woven fabric sandwiched between them. , and the calculation section 24
, the receiving section 26, the notifying section 28, and the transmitting section 30 may be, for example, an IC card in which an IC device is built into a thin plastic card.

The transmitting section 30 can transmit a signal for identifying itself, such as a different frequency, for each ID card 12 produced, and the notifying section 28 can transmit a signal for identifying itself, such as a different frequency, for each ID card 12 produced. different types of notification signals can be emitted. For example, when transmitting a call signal to a visitor in possession of an ID card 12, a signal corresponding to the type of call, such as a call signal to a specific room or a call signal to an in-house telephone, is sent by changing the tone, frequency, signal period, etc. What is necessary is to control the output signal to the speaker so that the output signal is changed and emitted.

As shown in FIG. 1, a switching antenna 32 is installed in the population of the intelligent building 0. Since all visitors have an ID card 12, they must pass through this switching antenna 32 at the entrance of the intelligent building IO. The transmission signal from the switching antenna 32 activates the power switching section of the ID card 12 and the arithmetic section 24 starts operating, and at the same time, a signal is transmitted from the transmission section 30, which is detected by the switching antenna 32. Therefore, the repeater 34 individually stores each passing person, and supplies these stored contents to the general calculation means 36 shown in FIG. 4 as needed or by command.

Furthermore, as shown in FIG. 5, inside the intelligent building 10, bar antennas 40 are also disposed near a plurality of doors 38, and they send signals to the ID cards 12 of visitors passing through the doors 38 to identify them. The transmitter 30 of the card is activated, and the signal from the transmitter 30 is received again by the bar antenna 40 and sent to the repeater 34.

This repeater 34 is similar to the repeater 34 of the switching antenna 32, but it can also select ID cards 12 and control the opening/closing of the door 38 to select persons passing through or entering a specific floor or room. can.

Furthermore, FIG. 6 shows an example of a per antenna 40 placed in a conference room 42, which, like the bar antenna 40, sends outgoing signals to the ID card 12 and receives outgoing signals from the ID card 12. The signal is sent to a repeater 34. Therefore, this repeater 34 is connected to any I/O in the conference room 42.
Ascertain whether there is a visitor in possession of D card 12,
Like the other repeaters 34, it is connected to a general calculation means 36. The repeater 34 also controls the operating states of the air conditioner 43A, lighting 43B, etc. according to the number of people in the conference room 42, making it possible to provide appropriate air conditioning and lighting with the minimum amount of energy. There is.

Further, FIG. 7 shows an office computer 44 as an example of an OA device. An ID card insertion section 46 is provided in a part of the office computer 44, and the office computer 44 is activated by inserting the ID card 12 into this section. For this purpose, the insertion section 46 is provided with a transmitting/receiving means or a device that directly contacts the 10 card 12 to transmit and receive data. In this office computer 44, the office computer 4
ID cards 12 can be sorted to identify the operator of 4 and the person who can access a specific storage device. Also, this office computer 44 is connected to the repeater 34.
A signal can be sent to the general calculation means 36 via the ID card to notify the location of the ID card.

As shown in FIG. 1, a bar antenna 40 is similarly arranged in the elevator hall 50, which is the entrance to the plurality of elevators 4B in the intelligent building 10, and performs the same transmission and reception as the bar antennas. The repeater 34 detects the number of ID cards 12 present in the hall 50, that is, how many people are waiting in the elevator hall 50 on each floor.

The overall calculation means 36 receives a signal from the repeater 34 and controls elevator control means such as a drive motor according to the number of users.

FIG. 9 shows evacuation guidance means 52 in an emergency. This evacuation guidance means 52 is preferably provided at a branching route on each floor, and guidance displays 54 and 56 indicating different evacuation routes are provided.
．． 58 are provided.

In addition, these guidance displays 54 are included in this evacuation display means 52.
．． 56. A light source corresponding to 58 is provided, and either one of the guidance displays 54 is
．． 56 and 58 to display the optimal taxi route for each level and the different taxi routes for each time.

In other words, when there are many people entering the building on each floor, these people can be dispersed and guided safely to multiple emergency exits, and in the event of a fire, the safe evacuation route can be sequentially changed depending on the progress of the fire. (Figure 9 shows guidance display 5.
4 is illuminated).

As shown in FIG. 4, the building management device 60 is operated by the general calculation means 36. This building management device 60 is controlled by a general calculation means 36 that grasps the location of each visitor using signals from a repeater 34, and controls electricity, air conditioning, etc. according to the total number of visitors in the building IO. Optimal control becomes possible. - For example, by calculating the amount of fresh air required according to the number of visitors and the set temperature and humidity, and adjusting the amount and temperature of cold and hot water in the air conditioner, efficient and accurate predictive control can be performed. I can do it.

Further, the electronic exchange 6 controlled by the general calculation means 36
2 allows for appropriate electronic exchange depending on the number of visitors, making it possible to secure a large number of lines only in the necessary areas. Furthermore, since the location of the ID card 12 is confirmed for calls to individuals from inside and outside, the line can be quickly routed to the location.

Similarly, the plurality of OA systems 64 controlled by the integrated calculation means 36 are controlled by the I/O system 64 as explained based on FIG.
You can select the storage devices that can be accessed depending on the type of D card 12, check the operating status of each OA system,
It is also possible to check and calculate the usage time of each worker. Furthermore, the external communication system 66 controlled by the integrated calculation means 36 can be similarly controlled efficiently.

Next, the operation of this embodiment will be explained.

Each visitor carries an ID card 12 in advance, and each visitor is handed an ID card 12 at the reception desk, and each visitor enters the intelligent building 10 with the ID card 12 in hand. In this case, the ID card 12 that is handed out is an ID card 12 that has different call types depending on the degree of need, and is shown in FIG. 5 so that only a specific visitor can move to a specific floor or a specific room. Opening/closing control of the door 38 and the like is performed.

In this way, the repeater 34 recognizes that the visitor is in a specific location on a specific floor using the switching antenna 32, the bar antenna 40, and the like.

The overall calculation means 36 receives the signal from the repeater 34 as necessary, and grasps the number of people in each floor, each room, and each location such as the elevator hall.

This allows efficient control of the elevator 48. In other words, if a large number of visitors gather on a specific floor and move to the same elevator hall 50,
By moving a large number of elevators 48 to this elevator hall 50, these visitors can be quickly moved to a desired floor.

Further, when a specific visitor is called from outside the intelligent building 10 or from other parts within the intelligent building 10, the call can be made quickly.

As an example, when calling a holder of a specific ID card from another part of a building, the caller calls the electronic exchange 62 using a call dial from a handset at hand. In this case, the handset to be used is equipped with an office computer 44 and a fil ID card insertion part 46,
This may be connected to the general calculation means 36 via the repeater 34.

The electronic exchange 62 sends a signal to the general calculation means 36 to investigate where the called ID card 12 is located. That is, the integrated calculation means 36 calculates all the repeaters 3.
4 to find out which repeater 34 is aware of the called ID card 12. This ID card 1
The repeater 34 that knows the ID card 2 sends a confirmation signal that it knows the ID card and the repeater number to the integrated calculation means 36, and a calling signal is sent to the called ID card via this repeater. Sent.

As a result, the calling unit 30 of the called ID card 12
Since a calling signal is transmitted from the station, the called visitor can sense this. This visitor calls the electronic exchange 62 using the nearest handset. Here electronic exchange 6
2 not only tells the called visitor who is the caller, but also connects the caller's handset to the called visitor's handset.

Furthermore, in the event of an emergency such as a fire, the general calculation means 3G can provide evacuation guidance according to the number of people entering the building on each floor. In other words, the optimal evacuation route is determined according to the number of people entering the building on each floor, and the guidance display of the evacuation guidance means 52 shown in FIG. This enables prompt and safe evacuation guidance.

In addition, since each repeater 34 knows in which floor and in which part of the building occupants who were unable to evacuate after a fire broke out, it is possible to determine whether or not rescue operations are necessary. In addition, it is efficient because it is possible to go directly to the location of the remaining person and rescue them.
