FIG. 12B is a schematic diagram showing a second procedure for installing wireless communication apparatus 102 at a predetermined place. FIG. 12C is a schematic diagram showing a third procedure for installing wireless communication apparatus 102 at a predetermined place.

  First, as a first procedure, as shown in FIG. 12A, a predetermined command is transmitted from a wireless terminal device 1201 such as a smartphone or a tablet to the wireless communication device 102 through a short-range wireless interface. Then, the wireless terminal device 1201 receives the device ID 805 from the wireless communication device 102 and acquires the device ID 805 of the wireless communication device 102.

  Next, as a second procedure, as shown in FIG. 12B, the wireless terminal device 1201 wirelessly transmits the accessory ID 401 encoded with the two-dimensional code attached to the first housing 103 or the second housing 108. The image is captured by a camera built in the terminal device 1201 and decoded. Then, the wireless terminal device 1201 acquires the accessory ID 401 of the wireless communication device 102.

Finally, as a third procedure, as shown in FIG. 12C, the wireless terminal device 1201 adds a user ID and a wireless ID in addition to the device ID 805 acquired in the first procedure and the accessory ID 401 acquired in the second procedure. A set of latitude and longitude information that can be obtained from GPS incorporated in the terminal device 1201 is transmitted to the measurement data server 105.
The measurement data server 105 additionally records the device ID 805, the accessory ID 401, the user ID, and the latitude / longitude information received from the wireless terminal device 1201 in the device master 1006.

[First Embodiment: Measurement Data Server 105: Service for Terminal Device]
FIG. 13 is a timing chart showing a procedure in which the measurement data server 105 transmits data obtained by performing predetermined arithmetic processing in response to a request from the wireless terminal device 1201.
First, when the wireless terminal device 1201 executes a predetermined application program, the wireless terminal device 1201 performs user authentication on the measurement data server 105 according to a predetermined procedure (S1301). At this time, the user ID has been transmitted from the wireless terminal device 1201 to the measurement data server 105 (S1302), and the measurement data server 105 has grasped the user ID of the wireless terminal device 1201.

  Next, when the user operates the touch panel display of the wireless terminal device 1201, the wireless terminal device 1201 displays a map of the paddy field 503 where the wireless communication device 102 is installed and the surrounding area on the touch panel display (S1303). Then, simultaneously with the display of the map, the latitude and longitude range on which the map is displayed is transmitted to the measurement data server 105 (S1304).

  Upon receiving the latitude and longitude range from the wireless terminal device 1201, the search processing unit 1004 of the measurement data server 105 refers to the device master 1006. The search processing unit 1004 narrows down the device master 1006 using the user ID acquired in step S1302 and the latitude and longitude range acquired in step S1304. Then, a record of the wireless communication device 102 belonging to the user ID and included in the latitude and longitude range is hit. That is, the measurement data server 105 acquires the device ID 805 from the device ID field of the hit record and the latitude / longitude from the latitude / longitude field (S1305).

  Next, the search processing unit 1004 acquires the accessory ID 401 from the accessory ID field of the record hit in step S1305. Then, the accessory master 1007 is searched by the accessory ID 401. The search processing unit 1004 acquires the process ID from the process ID field of the record that has been found in the search, and specifies a function for processing data of the wireless communication device 102 (S1306).

  Next, the search processing unit 1004 searches the log table 1003 with the device ID 805 obtained at the time of step S1305, and obtains necessary data from the data group field of the hit record. Then, the search processing unit 1004 performs a predetermined calculation process by giving the data acquired from the data group field to the function associated with the process ID acquired in step S1306. Then, the search processing unit 1004 transmits the processed data obtained as a result of the arithmetic processing to the terminal device together with the latitude and longitude acquired in step S1305 (S1307).

Upon receiving the latitude and longitude of the wireless communication device 102 and the processed data from the measurement data server 105 (S1308), the wireless terminal device 1201 displays a marker at a corresponding location on the map displayed on the touch panel display and processes the marker. The data is embedded (S1309).
Thereafter, each time the latitude and longitude or the scale of the map displayed on the touch panel display is changed, the processing from step S1303 to step S1309 is repeated.

  In general, measurement data is often recorded in a log file or a log table 1003 without any processing. On the other hand, the wireless communication device 102 according to the embodiment of the present invention assumes that various types of sensors are connected. For this reason, it is necessary to change the arithmetic processing on the data according to the types of the sensors.

  For example, the water level sensor 501 converts the voltage data into water level data through a predetermined calculation. For example, in the case of a barometric pressure sensor, voltage data is converted into barometric pressure data through an operation involving an offset value, a multiplication value, and the like.

Further, for example, in the case of the wireless communication device 102 mounted in the second housing 108, the application program of the wireless terminal device 1201 does not need the function of displaying a map. Therefore, if user authentication is performed in step S1301 and the user ID is passed to the measurement data server 105 in step S1302, steps S1303 and S1304 are unnecessary.
Then, in step S1305, the search processing unit 1004 narrows down and searches the device master 1006 by the user ID to obtain a list of device IDs 805.
Further, in the search processing of the log table 1003 in step S1307, temperature data and humidity data for a predetermined period from the latest are acquired and transmitted to the wireless terminal device 1201. The application program of the wireless terminal device 1201 displays a list of the wireless communication devices 102 belonging to the user ID, and displays a change in temperature and humidity in the selected wireless communication device 102 on a graph.

  As described above, the measurement data server 105 selectively uses appropriate data processing according to the operation mode of the common wireless communication device 102. The switching of the data processing is performed by a function related to the accessory ID 401 attached to the accessory associated with the wireless communication apparatus 102.
