1). The data logger processor 21 determines whether the collection time has been reached (S402) when the command to arbitrarily collect data is not included (S401; NO). The data logger processing device 21 waits for collection until the collection time is reached (S401-S402; NO).

Here, when the collection time has been reached (S402;
YES), the data logger processing device 21 outputs the main engine data and the EO flow rate from the various sensors 35, 35,.
The integrated range and the number of revolutions are taken in, and in the case of an analog signal, they are converted into an analog signal.

O), returning to step S411 again to continue the processing.
On the other hand, when the command indicating the last data is received (S413; YES), the server machine 20 ends the data collection and storage process.

FIG. 12 is a flowchart for explaining the operation in which the server machine 20 sends the onboard data to the land information processing apparatus 5. The flowchart shown in FIG. 12 is executed by the server machine 20 at regular intervals.

When the server machine 20 executes the flowchart shown in FIG. 12, first, it is determined whether it is time to send the onboard data to the land (S421). Here, when the server device 20 determines that the transmission time has not been reached (S421; NO), the server device 20 next determines whether an arbitrary transmission command has been entered (S422). Here, when an instruction to be arbitrarily transmitted is not included (S
422; NO), the process leaves this flowchart and shifts to another process.

On the other hand, when the time for transmitting the onboard data to the land (for example, 12:00) has been reached (S421;
YES), first, a file 60 as shown in FIG.

Reads out the inboard data from the storage device in a predetermined order and performs serial conversion (S424).

The server machine 20 stores the file 601
(See FIG. 5 (a)) first, and
01, the serialized data is transmitted (S42).
5). As a result, this data is transmitted from the maritime satellite communication device 22 to the communication satellite 3 via the hub 24 and the onboard personal computer 27.
Sent to The server machine 20 stores the file 601
It is determined whether or not all data has been transmitted (S42).
6), if not all have been transmitted (S426; NO), the data of the next channel in the storage device is designated (S42).
7), the process proceeds to step 424 again. Again, the server device 20 reads the data of the next channel (see FIG. 4) from the storage device, converts the data into a serial (S424), and sends out the serialized data (S425).

On the other hand, when the server machine 20 determines that the time for sending has not reached (S421; NO),
Next, it is determined whether or not an instruction to be sent arbitrarily is included (S422). Here, when an instruction to be sent arbitrarily is included (S422; YES), first, a file 602 ( N 01 1999 06 ) as shown in FIG.
08 12 05 . CSV ) is created (S423).
Then, the server machine 20 reads out the inboard data from the storage device in a predetermined order and performs serial conversion (S42).
4).

The server machine 20 stores the file 602
(See FIG. 5 (b)) first, and
02, the serially converted data is transmitted (S42).
5). As a result, this data is transmitted from the maritime satellite communication device 22 to the communication satellite 3 via the hub 24 and the onboard personal computer 27.
Sent to

The server machine 20 determines whether or not all the data of the file 602 has been transmitted (S426).
If all data has not been transmitted (S426; NO), the data of the next channel in the storage device is designated (S427), and the process returns to step 424 again. Again, the server machine 20
The data of the next channel (see FIG. 4) is read out from the storage device, serially converted (S424), and the serialized data is transmitted (S425).

The serialized inboard data transmitted in this manner includes “channel number”, “numerical data A”,
Since it is separated by a comma from “Numerical data B”, “Numerical data C”,..., There is no need to send a special framework or other data that maintains the signal format or display format. Becomes shorter. The first “numerical data” after the channel number is, for example, data collected at 16:00, and the second “numerical data” is, for example, data collected at 20:00. Since the data format is known in advance, the land information processing device 5
