  In order to provide information services to an existing building without network facilities, it is desirable that the cost of laying work is as low as possible. In order to transmit a large amount of information such as video, an optical cable is required, but in order to prevent signal attenuation, it is necessary to keep the bending and twisting of the optical cable within a predetermined range. The elevator described in Patent Document 1 does not sufficiently consider these problems when using an optical cable to transmit a large amount of information.

  In the network described in Patent Document 2, it is described that a cable is laid in an apartment, but it is difficult to perform unified work such as using a different provider for each home for Internet connection. Also, this publication does not take into account various problems when adding an information service when renewing an existing apartment. It is also difficult to determine the cost sharing when newly laying a communication cable in an existing apartment.

  The present invention has been made in view of the above problems of the prior art, and an object thereof is to easily construct a network not only in a new building but also in an existing building. Another object of the present invention is to create a unified network in a building.

In order to achieve the above object, the present invention is characterized in that an information service is provided in a building having an elevator in which a control signal is transmitted between a control panel in a hoistway and an elevator landing on each floor via a control cable. A separator provided for each floor in a hoistway and connected to each other by the control cable and for branching an external communication signal and a call signal for the information service; and any one of the separators An elevator control panel connected to a server connected to the Internet via the Internet, a call button connected to each separator via a converter, the separator, the converter, and the call button are accommodated from the separator to each floor. A call device having a terminal to which a communication cable can be connected. In which the terminals are connected.

Moreover, in the above, it is preferable that the connection of the separator from the control cable and the Internet, and the connection of the terminal from the separator are performed by an optical cable.

Furthermore, in the above, it is preferable that the terminal is attached upward.

  Hereinafter, some embodiments according to the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram of an embodiment of a communication system having a building communication apparatus according to the present invention. A network is constructed using the elevator hoistway 100. Connect the server 102 to the Internet 101. The server 102 is connected to an optical cable 103a disposed in the hoistway 100 of the building. The optical cable 103a is connected to a separator 104a provided in the hoistway 100, which is a basement or a lower floor.

  Optical cables 103b, 103c, 103d,... Leading to the upper floor are connected to the separator 104a via separators 104b, 104c, 104d,. Each of the optical cables 103b, 103c, 103d,... And the separators 104b, 104c, 104d,. The separator 104a is also connected to the elevator control panel 105 via a connection line 105a. Therefore, the output signal of the server 102 is supplied to the elevator control panel 105 on the one hand by the connecting line 105a connected to the separator 104a, and on the other hand to the separators 104b, 104c provided in the hoistway 100 corresponding to each floor. Are transmitted to each floor by optical cables 99b, 99c, 99d,.

  The signals transmitted through the optical cables 103b, 103c, 103d,... Connecting the separators 104b, 104c, 104d,. Branch to signal. For example, the elevator call signal generated by the elevator call button 106 provided on the c-th floor is converted into an optical signal by the converter 107 and output to the separator 104c. The call signal is transmitted from the separator 104c to the control panel 105 to control the elevator. At this time, the control panel 105 prevents an elevator control signal from flowing out of the server 102 to the outside, and prevents an external signal from interfering with the elevator control signal.

  Separator 104c, call button 106, and converter 107 are housed in call device 109. The calling device 109 has a terminal 108 to which an optical cable 99c is connected. A cable 98c branched from the separator 104c for communication on each floor is connected to the terminal 108. A hub 110 for developing signals on the floor is connected to the optical cable 98c on each floor. A terminal 111 is connected to the hub 110. In this embodiment, the calling device 109 connects the optical cables 103b, 103c, 103d,... Disposed in the hoistway 100 to the optical cables 98b, 98c, 98d,.

  FIG. 2 is a perspective view of the calling device 106 installed on each floor. The signal input to the separator 104 is input to a converter 107 that converts an optical signal into an electrical signal through the optical cable 103p and vice versa, and to an external connection terminal 108 through the optical cable 103q. The external connection terminal 108 is attached upward, and an optical cable 98 from the outside is wired upward along the wall. Thereby, when the optical cable 98 is wired along the wall, the bending of the optical cable 98 is reduced as much as possible to reduce the space necessary for the cable wiring.

  A connector 301 connected to the call button 106 is connected to the converter 107 via wiring. The separator 104, the converter 107, and the terminal 108 are accommodated in the apparatus base 109b. A cover 109a including a call button 106 is attached to the base 109b.

  According to the present embodiment, since the communication in the building is executed by the control cable for the elevator, there is no need to newly install a communication cable for in-building communication even when the existing building is renewed. . Moreover, since the calling device has a terminal, it is not necessary to form a hole for taking out the optical cable from the hoistway in the partition between the hoistway and the outside of the hoistway. Furthermore, since each terminal is connected to the calling device, a service application including control for calling an elevator from each terminal can be easily incorporated into each terminal. In the above-described embodiment, the cable extraction terminal 108 is attached upward. However, any direction may be used as long as the curvature at the extraction portion of the cable 99c for extraction does not increase.

  Another embodiment of the building communication apparatus according to the present invention is shown in a perspective view in FIG. The main difference between the present embodiment and the embodiment shown in FIG. 1 is that the information communication cables 103a, 103b, 103c,... , 202 are arranged separately, and the information communication cables 103a, 103b, 103c,... Transmit monitoring information in the car 204 as well. The server 102 is connected with a communication line 201 for elevator control and an optical cable 103a for in-building communication. The optical cable 103a is drawn into the hoistway 100 in the building by the bending take-out device 207.

  The communication line 201 is connected to the elevator control panel 105. Call buttons 106 b, 106 c, 106 d,... On each floor are connected to the control panel 105 via communication lines 202. A signal photographed by the monitoring camera 205 installed in the elevator car 204 is input to the control panel 105 via the communication line 203. A signal from the monitoring camera 205 is transmitted to the server 102 via the communication line 203, the control panel 105, and the communication line 201.

  The signal of the monitoring camera 205 input to the server 102 is transmitted to the display 206 on each floor via the optical cables 103a, 103b, 103c,... And the separator 104 provided on each floor. A signal transmitted through the optical cable 402 branched by the separators 104b, 104c, and 104d is taken out to each floor via the bending take-out device 207, and is input to the terminal 111 from the hub 110 on each floor. According to the present embodiment, since the signal of the monitoring camera 205 provided in the car 204 can be distributed to the display 206 on each floor and each terminal 11, there is a crime prevention effect.

  FIG. 4 shows, in a longitudinal section, a bending take-out device 207 that is connected to the optical cable 402 and takes out the optical cable 403 to each floor. A bend take-out device 207 is attached to the partition wall 401 forming the elevator hoistway 100. Since the optical cables 402 and 403 need to have a large bending radius, the bend extraction device 207 has a mirror 404 that bends the direction of the light beam by approximately 90 degrees.

  According to the present embodiment, since information is communicated into the building with a cable for transmitting information to the display on each floor, it is necessary to newly lay communication cables in the building even when the existing building is renewed. There is no. Moreover, since the bending take-out device 207 is attached using the holes for taking out the optical cables 103b, 103c, 103d,... From the hoistway 100, the space necessary for bending the optical cables 103b, 103c, 103d,. Since the signal of the display device 206 installed in front of the hall is input to each terminal 111, the video of the security camera 205 in the car displayed on the display device 206 can be easily viewed on each terminal 111, There is a crime prevention effect.

  Another example of taking out the optical cable from the hoistway 100 to each floor is shown in FIG. FIG. 5 is a view of the elevator hoistway 100 as viewed from above. In the hoistway 100, an optical cable 103 is disposed on the partition wall 401. In addition to the optical cable 103 that transmits signals to the upper and lower floors, an optical cable 120 is branched from the separator 104. A through hole 402 is formed through the wall surface of the partition wall 401 obliquely. In this embodiment arranged in this way, the optical cable 120 passes through the wall 401 and through the wall 401 so as to be taken out to each floor, so that it does not disturb the passage space of the elevator car in the hoistway 100. Further, the curvature of the optical cable 402 can be increased.

  An example of a building system using the building communication apparatus according to the present invention will be described with reference to FIG. FIG. 6 is a schematic diagram of a building system. A personal computer or the like of each user 504 who lives in the building is connected to the communication cable taken out from the elevator hoistway 100 to each floor via the take-out means. The personal computer of each user 504 is connected to the Internet 101 connection service provided by the communication company 502. At that time, in order to enable each user 504 residing in the building to connect to the outside of the building via the Internet, the in-building wiring trader 506 manages the network owned by the user. Each user 504 individually makes a connection contract with the communication carrier 502 and pays a usage fee. At this time, the communication company 502 contracted for each user 504 may be different.

  The amount of information that each user 504 enjoys from the communication company 502 is measured by the server 102. The amount of information to be measured is, for example, the connection time of each user 504 and the amount of data transmitted / received. These pieces of information are stored in a database 505 attached to the server for each communication company 502 used by each user 504. The communication company 502 pays the laying construction cost and the network usage fee in the building to the in-building wiring company 506.

  In order to share the usage fee according to the usage amount of the network, the in-building wiring company 506 refers to the history database 505 stored in the server 102 and extracts the access history of each user 504. From the history for each user 504, the usage fee calculation means 507 calculates the network usage fee that the communication company 502 should bear. The usage fee calculation means 507 determines the share rate of the total fee based on the use rate of the user 504 to be borne by each communication provider 502 in the total connection time and / or the total amount of transmitted / received data. Each communication company 502 pays the determined usage fee to the in-building wiring company 506. According to the present embodiment, even if there are a plurality of communication companies 502, the cost according to the usage amount that the communication company should bear can be determined fairly.

  It should be noted that the data on the usage amount for each communication company 502 obtained by the usage amount calculation means 507 may be transmitted to the in-building delivery company 506 from a communication line used for remote monitoring of the elevator. In this case, it is not necessary for the in-building wiring company 506 to go to the site to calculate the usage amount. In addition, since a common communication line is used for remote monitoring of the elevator, a new communication service contract is unnecessary.

  FIG. 7 shows another example of a building system using the building communication apparatus according to the present invention. FIG. 7 is a schematic diagram of a building system. By connecting the optical cable to the communication means stretched around each floor of the existing or new building, the building residents can use the communication environment in the same way as the new building. The in-building wiring company 506 makes a contract with the communication company 502 so that each user 504 can use the network owned by the in-building wiring company 506. Each user 504 updates existing communication means to new communication means. Each user 504 pays the in-building wiring company 506 a fixed communication fee equivalent to the conventional communication means and a usage fee according to the communication amount. The in-building wiring company 506 pays the communication company 502 the communication cost for the new communication means. When the communication cost of the new communication means is small compared to the conventional communication cost, the initial construction cost is recovered from the difference, and the network maintenance cost is generated.

  According to the present embodiment, it is possible to construct a network of new communication means in a building without making a new investment for each user, and to share the costs associated with laying work fairly. Therefore, new communication means can be easily laid even when the building is sectioned and owned.
