  Main device 20 transmits a request signal for requesting transmission of sensor information to base station device 10 via communication line CL (S101).

  When receiving the request signal from the main device 20, the line unit 14 of the base station device 10 transmits the request signal to the control unit 12 (S102). The control unit 12 supplies an information transmission request for sensor information to the sensor unit 11 in response to the request signal received from the main device 20 via the line unit 14 (S103).

  The sensor unit 11 supplies a data signal indicating the sensor information to the control unit 12 in response to the information transmission request from the control unit 12 (S104). The sensor unit 11 may detect the state of the building only when there is an information transmission request from the control unit 12, for example, and may transmit the sensor information as a detection result to the control unit 12. Further, regardless of the presence or absence of the information transmission request from the control unit 12, the state of the building is periodically detected and the sensor information is held, and the held sensor information is used in response to the information transmission request from the control unit 12. May be supplied to the control unit 12.

  The control unit 12 transmits the data signal supplied from the sensor unit 11 to the line unit 14 (S105). The line unit 14 transmits the data signal transmitted from the control unit 12 to the main device 20 (S106).

  Main device 20 transmits the data signal received from line unit 14 of base station device 10 to monitoring center device 30 (S107). In the present embodiment, the main device 20 transmits a data signal to the monitoring center device 30 via the telephone network.

  The monitoring center device 30 receives the data signal, and collects, stores, and analyzes the data (S108). The monitoring center device 30 monitors the inclination of the building in which the base station device 10 is installed, for example, based on a temporal change of a data signal indicating a detection result by the sensor unit 11 of the base station device 10.

  Through the above processing steps, the inclination of the building where the base station device 10 is installed is monitored as the state of the installation location of the base station.

  The base station apparatus 10 according to the present embodiment has a function of detecting the inclination of the place where the base station apparatus 10 is installed by the sensor unit 11 in addition to the function as an original base station for providing a telephone service to the mobile terminal T1. Having. Therefore, it is not necessary to arrange another sensor or device outside the base station apparatus 10 or the like in order to monitor the state of the building or the like in which the base station apparatus 10 is installed. In addition, since it is possible to easily monitor the state of the building where the base station device 10 is installed, it is possible to prevent a reduction in inspection frequency.

  Next, a second embodiment of the present invention will be described. FIG. 4 is a block diagram illustrating the configuration of the communication system 200 according to the second embodiment.

  The communication system 200 according to the first embodiment is different from the communication system 100 according to the first embodiment in that the communication system 200 includes a And different.

  The wireless transceiver 31 is provided outside the base station device 10 and is connected to the monitoring center device 30 by wire or wirelessly. The wireless transceiver 31 receives a request signal for requesting sensor information from the monitoring center device 30 and transmits the received request signal to the base station device 10. Further, the wireless transceiver 31 receives a data signal indicating the sensor information from the wireless unit 13 of the base station device 10 and transmits the received data signal to the monitoring center device 30.

  Next, the operation of the communication system 200 of the present embodiment will be described with reference to the sequence diagram of FIG.

  The monitoring sensor 30 transmits a request signal for requesting transmission of sensor information to the wireless transceiver 31 (S201). The wireless transceiver 31 receives the request signal from the monitoring sensor 30, and transmits the received request signal to the base station device 10 by wireless (S202).

  The wireless unit 13 of the base station device 10 receives the request signal transmitted from the wireless transceiver 31 and transmits the received request signal to the control unit 12 (S203). The control unit 12 supplies an information transmission request for requesting transmission of sensor information to the sensor unit 11 in response to the request signal from the monitoring center device 30 received via the wireless unit 13 (S204).

  The sensor unit 11 supplies a data signal indicating the sensor information to the control unit 12 in response to the information transmission request from the control unit 12 (S205). The sensor unit 11 may detect the state of the building only when the information transmission request is received from the control unit 12, as in the first embodiment. Regardless, the state of the building may be periodically detected.

  The control unit 12 transmits the data signal supplied from the sensor unit 11 to the wireless unit 13 (S206). The wireless unit 13 wirelessly transmits the data signal transmitted from the control unit 12 to the wireless transceiver 31 (S207).

  The wireless transceiver 31 transmits the data signal received from the wireless unit 13 of the base station device 10 to the monitoring center device 30 (S208).

  The monitoring center device 30 receives the data signal, and collects, stores, and analyzes the data (S209). The monitoring center device 30 monitors the inclination of the building in which the base station device 10 is installed, for example, based on a temporal change of a data signal indicating a detection result by the sensor unit 11 of the base station device 10.

  Through the above processing steps, the inclination of the building where the base station device 10 is installed is monitored as the state of the installation location of the base station.

  According to the communication system 200 of the present embodiment, unlike the communication system 100 of the first embodiment, it is possible to monitor the state of the installation location of the base station without passing through the main device 20.

  Further, similarly to the first embodiment, the base station device 10 of the present embodiment is also provided with the base station device 10 installed by the sensor unit 11 in addition to the function as the original base station for providing the telephone service to the mobile terminal T1. It has a function to detect the inclination of the place where it is. Therefore, since it is not necessary to separately provide a sensor or device for monitoring the state of the building or the like where the base station is installed outside the base station apparatus 10, the monitoring can be easily performed and the frequency of inspection can be reduced. This can be prevented.

  Note that the present invention is not limited to the above embodiment. For example, in the above-described embodiment, a case has been described where the main device 20 is a telephone exchange such as an electronic exchange or a digital exchange and is connected to a telephone line network. However, the main device 20 may be an IP-PBX (Internet Protocol Private Branch Exchange). In this case, the main device 20 is connected to the monitoring center device 30 via IP instead of the telephone line network (IP connection), and transmits a data signal to the monitoring center device 30 via IP. According to such a configuration, it is also possible to perform monitoring by connecting to a higher-level IP network.

  Further, in the above-described embodiment, the case where the sensor unit 11 includes the acceleration sensor and detects the inclination of the installation location where the base station device 10 is installed based on the gravitational acceleration has been described. However, the type of the sensor is not limited to the acceleration sensor, and the sensor unit 11 may detect the inclination of the installation location using another sensor.

  The sensor unit 11 may detect information other than the inclination of the building as the state of the installation location (parameters of the installation location and its surrounding environment). For example, the sensor unit 11 may detect the temperature of the installation location using a temperature sensor. According to such a configuration, it is possible to monitor the temperature near the base station.

  Further, in the above-described embodiment, an example in which the base station apparatus 10 transmits a data signal indicating sensor information to the monitoring center apparatus 30 via the main apparatus 20 or the wireless transceiver 31 and performs collection, accumulation, and analysis will be described. did. However, the transmission destination of the data signal is not limited to the monitoring center device 30. For example, the base station apparatus 10 may wirelessly transmit a data signal indicating sensor information to a mobile terminal located within a range of its own communication area (cell). Thereby, the terminal user who uses the mobile terminal can perceive the state of the building in real time, and can take evacuation behavior or the like as necessary.

  In the above-described embodiment, a building is exemplified as a form of a building. For example, the building may be a gate, a fence, a telephone pole, a tunnel, a bridge, a culvert, a building, or the like, which is attached to land (ground or underground). Or a building having a roof and pillars or walls among the works fixed on the land (the ground or the underground). For example, a building is a cave (a hole made in a cliff or a rock) that is not something that a human or a machine (robot) has worked on (made by modifying materials), but that houses a living thing. Or used for other purposes.
