- the priority setting unit 134 sets priorities for each of the six communication modes shown in Table 1 based on the first evaluation value and the second evaluation value obtained in S201. How to determine the priority based on the first evaluation value and the second evaluation value is set in advance. For example, the priority setting unit 134 creates a second priority list by correcting the first priority list stored in the storage unit 137 using the second evaluation value obtained in S201 (S202). The second priority list generated by the priority setting unit 134 is stored in the storage unit 137 (S203). Table 3 shows an example of the second priority list stored in the storage unit 137 in S203.
- the second measurement condition is a condition for the measurement unit 142 to start measurement of communication quality.
- the second measurement condition is set in advance.
- the second measurement condition may be the same as the condition for starting the communication for life and death monitoring.
- the measurement unit 142 measures communication quality between the communication unit 143 and the data center 200 again (S205).
- the priority setting unit 134 resets the priority for each of the six communication modes shown in Table 1 based on the first evaluation value and the second evaluation value obtained in S205.
- the priority setting unit 134 may reset the priority using both the latest value and the past value of the first evaluation value.
- the priority setting unit 134 may reset the priority using both the latest value and the past value of the second evaluation value.
- the priority setting unit 134 updates the second priority list based on the reset priority (S206). Thereby, the storage unit 137 stores the second priority list in which the latest second evaluation value is reflected.
- FIG. 5 is a flowchart showing another operation example of the monitoring device 120.
- the monitoring device 120 determines whether it is necessary to transmit data to the outside (S301). For example, the state data collected by the data collection unit 131 is periodically transmitted to the data center 200. When voice data is input from the intercom 113 to the interphone control unit 132, the voice data is immediately transmitted to the information center 300.
- the selection unit 133 selects one communication mode as a connection mode from the six communication modes shown in Table 1 (S302).
- FIG. 6 is a flowchart showing an example of connection mode selection. FIG. 6 shows the contents of processing performed in S302.
- the selection unit 133 determines whether the second priority list is stored in the storage unit 137 (S401). For example, immediately after the elevator 110 is installed in the building 100, the second priority list is not stored in the storage unit 137. In this case, the selection unit 133 selects the connection mode based on the first priority list stored in the storage unit 137 (S402). For example, the selection unit 133 selects, as the connection mode, the communication mode listed at the top of the first priority list. As a result, the communication mode in which the priority set by the priority setting unit 134 is the highest at that time is selected as the connection mode.
- the selection unit 133 selects the connection mode based on the stored second priority list (S403). For example, the selection unit 133 selects the communication mode listed at the top of the second priority list as the connection mode. As a result, the communication mode with the highest priority at that time reflecting both the first evaluation value and the second evaluation value is selected as the connection mode.
- the communication unit 143 transmits data to the outside of the building 100 in the communication mode selected in S302, that is, in the connection mode (S303). For example, the communication unit 143 transmits the state data collected by the data collection unit 131 to the data center 200 in the connection mode. The state data transmitted in S303 is received by the server 210 via the IP network 401.

- the storage unit 137 stores information on the connection prohibition mode.
- FIG. 10 illustrates an example in which the connection prohibition mode is excluded from the connection mode selection candidates according to the type of data transmitted by the communication unit 143.
- voice communication is performed in 3G or 4G. This is because 2G does not support voice communication. Therefore, the communication unit 143 can not transmit voice data using 2G of the communication carrier A or 2G of the communication carrier B among the six communication modes shown in Table 1.

On the other hand, if the second priority list is stored in the storage unit 137, the selection unit 133 selects the connection mode based on the second priority list (S805). That is, in S805, if voice data is included in the data to be transmitted by the communication unit 143, the selection unit 133 selects one of the six communication modes excluding the connection prohibition mode, among the six communication modes. Select the communication mode listed above as the connection mode.

- the selection unit 133 determines whether the second priority list is stored in the storage unit 137 (S901). If the second priority list is not stored in the storage unit 137, the selection unit 133 determines whether the data transmitted by the communication unit 143 to the outside includes audio data (S902). If voice data is not included in the transmission data, the selection unit 133 selects the connection mode based on the first priority list (S904). For example, the selection unit 133 selects, as the connection mode, the communication mode listed at the top of the first priority list.
- the correction unit 136 corrects the priority set by the priority setting unit 134. That is, the correction unit 136 corrects the first priority list (S903). In general, it is said that voices can be heard more clearly if voice communication is performed with 4G rather than 3G when an analog call terminal is used. Therefore, if the first evaluation value and the second evaluation value are the same value, the correction unit 136 corrects the priority so that the order of 4G is higher than 3G. For example, by adding the correction value to the second evaluation value or the first evaluation value of 4G, 4G can be more easily selected as the connection mode than 3G.
- the order itself may not change due to the correction. Also, since 3G voice communication is possible, it is not necessary to specify 3G as the connection prohibition mode.
- the selection unit 133 selects the connection mode based on the first priority list corrected by the correction unit 136 (S904). For example, the selection unit 133 selects, as the connection mode, the communication mode in the top of the first priority list corrected by the correction unit 136.
- the selection unit 133 determines whether the data transmitted from the communication unit 143 to the outside includes audio data (S905). If voice data is not included in the transmission data, the selection unit 133 selects the connection mode based on the second priority list (S907). For example, the selection unit 133 selects the communication mode listed at the top of the second priority list as the connection mode.
- the correction unit 136 corrects the priority set by the priority setting unit 134. That is, the second priority list is corrected by the correction unit 136 (S906). For example, if the first evaluation value and the second evaluation value are the same value, the correction unit 136 corrects the priority so that 4G is higher than 3G. For example, by adding the correction value to the second evaluation value or the first evaluation value of 4G, 4G can be more easily selected as the connection mode than 3G.
- the selection unit 133 selects the connection mode based on the second priority list corrected by the correction unit 136 (S907). For example, the selection unit 133 selects, as the connection mode, the communication mode listed at the top of the second priority list corrected by the correction unit 136.
