Information, information required when communicating via the narrow-area wireless network N2, and the like are stored.

  The wide area wireless communication unit 34 performs wireless communication via the wide area wireless network N1 by transmitting and receiving radio waves through an antenna (not shown). For example, when the base unit 30 receives a message including the pointer value of the measuring device 50 from the slave unit 40 through the narrow area wireless communication unit 35, the base unit 30 transmits the message to the server 10 on the center side.

  In addition, when the radio wave is received by the antenna, the wide area radio communication unit 34 acquires a message by decoding the received radio wave. The wide area wireless communication unit 34 outputs a message obtained by decoding to the control unit 31. When acquiring a message output from the wide area wireless communication unit 34, the control unit 31 performs a process corresponding to the message and a process of transferring to the slave unit 40 through the narrow area wireless communication unit 35.

  The narrow-area wireless communication unit 35 communicates with a plurality of slave units 40 by a predetermined wireless communication method by transmitting and receiving radio waves through an antenna (not shown).

  FIG. 5 is a block diagram illustrating an example of the configuration of the setting device 60 according to the first embodiment. The setting device 60 can be configured by, for example, a tablet terminal device, a notebook computer, a smartphone, or the like. The setting device 60 includes a control unit 61 that controls the entire setting device, a display unit 62, an operation unit 63, a mail transmission unit 64, a short-range wireless communication unit 65, a camera unit 66, a storage unit 67, and the like. The setting device 60 can be carried by an operator who performs work such as opening processing at the installation site where the handset 40 is installed. In the present embodiment, the installation site is an installation location where the handset 40 connected to the measuring device 50 is installed. Further, the opening process is a process for determining whether or not the connection between the slave unit 40 and the measuring device 50 is appropriate.

In this specification, acquiring through the input unit means acquiring the pointer value measured by the measuring device 50 without using the electric wire 1 (the electric wire connecting the slave device 40 and the measuring device 50). It is.

  The mail transmission unit 64 allows the worker to transmit the created mail to the server 10 via the wide area wireless network N1. The e-mail can include, for example, a request for opening as a subject, a customer number as a body, and a guideline value of the measuring device 50.

  The short-range wireless communication unit 65 can perform short-range wireless communication with the handset 40. For example, the short-range wireless communication unit 65 can transmit an opening instruction to the child device 40.

  Next, before explaining the operation of the communication system according to the present embodiment, a guide value confirmation determination process at the time of opening is explained as a comparative example.

  FIG. 6 is an explanatory diagram showing an example of a pointer value confirmation determination process at the time of opening as a comparative example. At the time of opening, it is a state in which preparations for opening processing are completed. More specifically, wireless pairing between the parent device and the child device is completed, and the child device and the measuring device are connected by wire. State. First, the worker at the site where the handset is installed makes a request for opening (A1). Specifically, the opening request is made by contacting the center by telephone and, for example, contacting the center operator such as “Please open the house for Mr. XX”.

  In the center, the operator who receives the telephone operation performs an operation, and transmits a pointer value request to the slave unit via the master unit (A2). The subunit | mobile_unit which received the guide value request | requirement transmits a guide value request | requirement to a measuring device (A3). When the measuring device transmits the guideline value to the slave unit, the slave unit acquires the guideline value (A4). The slave unit transmits a pointer value response to the center (A5). Thereby, the center acquires the guideline value of the measuring device via the slave unit.

  The operator visually confirms the guideline value of the measuring device (A6), and informs the center of the confirmed guideline value (A7). In this case as well, the operator contacts the center and contacts the center operator, for example, “The guideline value of Mr. XX's house is △△. Is it consistent?”. In the center, the guideline value acquired through communication from the operator is compared with the guideline value acquired via the slave unit (A8), and if the two guideline values match, the slave unit is connected to the measuring device. Can be determined as being performed correctly, and it can be determined that the opening process has been completed.

  In the case of the comparative example as shown in FIG. 6, since the pointer value is confirmed by telephone, human errors such as misreading and misreading may occur. In addition, a center operator is required to confirm the result of the opening process. In addition, the worker at the installation site must wait at the installation site until the opening process is completed. Thus, in the case of the comparative example, the burden on the operator at the center and the operator at the installation site was large.

  Next, the operation of the communication system according to the present embodiment will be described.

  FIG. 7 is an explanatory diagram illustrating an example of a guideline value confirmation determination process at the time of opening by the communication system according to the first embodiment. Wireless pairing between the parent device 30 and the child device 40 is completed, and the child device 40 and the measuring device 50 are in a state where they are connected by wire, that is, in a state where they can be opened. The operator at the installation site inputs the pointer value of the measuring device 50 to the setting device 60 (P1). The operation unit 63 or the camera unit 66 can be used to input the pointer value.

  The worker transmits mail from the setting device 60 to the server 10 (P2). The e-mail can include the opening request as the subject, the customer number as the body, and the guideline value of the measuring device 50. The server 10 receives the mail transmitted by the setting device 60, acquires the guideline value acquired by the setting device 60, and registers the acquired guideline value (P3).

  When the opening instruction is transmitted from the setting device 60 to the child device 40 (P4), the child device 40 transmits a pointer value request to the measuring device 50 (P5), and the measuring device 50 transmits the measured pointer value to the child device 40. Send. Thereby, the subunit | mobile_unit 40 acquires a guideline value (P6).

  The subunit | mobile_unit 40 transmits an acquisition guideline value to the server 10 via the main | base station 30 (P7). When receiving the acquired guideline value, the server 10 transmits the guideline value (registered guideline value) transmitted from the setting device 60 to the slave unit 40 (P8).

  The subunit | mobile_unit 40 compares the registration guideline value (received value) received from the server 10, and the guideline value (acquired value) acquired from the measuring device 50 (P9), and determines a match / mismatch of both. If the two match, it can be determined that the connection between the child device 40 and the measuring device 50 is appropriate. If the two do not match, the connection between the child device 40 and the measuring device 50 is inappropriate ( For example, it can be determined that the slave unit 40 is not connected to the target measuring device 50).

  The subunit | mobile_unit 40 transmits a determination result to the setting device 60 (notification) (P10), and displays a determination result on the display part 42 (P11). The setting device 60 receives the determination result and displays the received determination result on the display unit 62 (P12).

  As described above, the slave unit 40 connects the guideline value measured by the measurement device 50 to the measurement device 50 and acquires the guideline value (setting device 60) transmitted from the server 10 via the connection unit 46 and the master unit 30. The handset 40 based on the guideline value acquired by the narrow-range wireless communication unit 44 and the guideline value received by the narrow-range wireless communication unit 44. And a determination unit 45 that determines whether or not the connection with the measuring device 50 is appropriate.

  When the pointer value acquired from the measuring device 50 by connecting the slave unit 40 to the measuring device 50 matches the pointer value acquired by the setting device 60 via the operation unit 63 or the camera unit 66 (input unit) It can be determined that the handset 40 is connected to the measuring device 50, and the opening process can be completed. Further, by transmitting the pointer value from the setting device 60 to the server 10, the determination unit 45 of the slave unit 40 can determine whether the pointer value matches or does not match. However, since it is not necessary to check the telephone with the center operator, the work load related to the opening process can be reduced.

  The subunit | mobile_unit 40 is provided with the display part 42 which displays the information regarding the determination result in the determination part 45. FIG. Thereby, the operator does not need to perform confirmation work with the operator of the center, and can easily confirm that the slave unit 40 is connected to the target measurement device 50.

  Even if the operator leaves the installation site while carrying the setting device 60 by transmitting the determination result in the determination unit 45 from the narrowband wireless communication unit 44 to the setting device 60, the operator can Since the determination result can be confirmed, it is not necessary to stay at the installation site until the determination result is obtained. Thereby, since the worker can go to the next installation site, for example, the work efficiency of the worker can be improved.

  The setting device 60 includes a short-range wireless communication unit 65 that transmits an opening instruction (measurement instruction) to the child device 40. The subunit | mobile_unit 40 will acquire a pointer value from the measuring device 50, if the opening instruction | indication is received from the setting device 60. FIG. As shown in FIG. 7, when the operator operates the setting device 60 and transmits an opening instruction to the child device 40, the child device 40 can acquire the pointer value from the measuring device 50. Since the operator can complete the opening process only by sending the opening instruction, the operator can leave the current installation site and go to the next installation site, for example, until the opening process is completed. There is no need to wait, improving workability.

[Embodiment 2]
FIG. 8 is an explanatory diagram illustrating an example of a guideline value confirmation determination process at the time of opening by the communication system according to the second embodiment. The difference from the first example shown in FIG. 7 is that when the slave unit 40 receives the registered guideline value transmitted from the server 10, it transmits a pointer value request to the measurement device 50 and acquires the guideline value from the measurement device 50. It is a point to do.

  As shown in FIG. 8, the worker at the installation site inputs the pointer value of the measuring device 50 to the setting device 60 (P1). The worker transmits mail from the setting device 60 to the server 10 (P2). The e-mail can include the opening request as the subject, the customer number as the body, and the guideline value of the measuring device 50. The server 10 receives the mail transmitted by the setting device 60, acquires the guideline value acquired by the setting device 60, and registers the acquired guideline value (P3).

  When the server 10 transmits the registered guideline value to the child device 40 via the parent device 30 (P4), the child device 40 transmits a pointer value request to the measuring device 50 (P5), and the measuring device 50 performs the measurement. The guideline value is transmitted to the slave unit 40. Thereby, the subunit | mobile_unit 40 acquires a guideline value (P6).

  The subunit | mobile_unit 40 compares the registration guideline value (reception value) received from the server 10, and the guideline value (acquisition value) acquired from the measuring device 50 (P7), and determines a match / mismatch of both. If the two match, it can be determined that the connection between the child device 40 and the measuring device 50 is appropriate. If the two do not match, the connection between the child device 40 and the measuring device 50 is inappropriate ( For example, it can be determined that the slave unit 40 is not connected to the target measuring device 50).

  The slave unit 40 transmits (notifies) the determination result to the server 10 via the master unit 30 (P8), transmits (notifies) the determination result to the setting device 60 (P9), and transmits the determination result to the display unit 42. Display (P10). The setting device 60 receives the determination result and displays the received determination result on the display unit 62 (P11).

  As described above, in the second example, similarly to the first example, the handset 40 is connected to the measuring device 50 and acquired by the setting device 60 through the input unit and the pointer value acquired from the measuring device 50. If the pointer value matches, it can be determined that the slave unit 40 is connected to the target measuring device 50, and the opening process can be completed. Further, by transmitting the pointer value from the setting device 60 to the server 10, the determination unit 45 of the slave unit 40 can determine whether the pointer value matches or does not match. However, since it is not necessary to check the telephone with the center operator, the work load related to the opening process can be reduced.
