Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data collecting device for collecting sensor information of agricultural machinery such as tractors and combine harvesters in order to grasp the working status of such machinery.

[0002]

2. Description of the Related Art With the rationalization of agricultural management and the high performance of agricultural machinery, various work data such as mileage per field or day, work area, fuel consumption, etc. are collected and used. It is becoming more and more important to weigh and compare the above items and use them for future work plans. The method that has been conventionally used to collect these data is to read the values of the fuel gauge and rangefinder attached to the agricultural machine at the start and end of the work and calculate the difference. The accuracy of the obtained data was low, and the data collection work and the data arrangement after the collection were troublesome.

Therefore, the applicant mounts the management terminal on an agricultural machine, connects the controller on the machine side and the management terminal with an optical communication line, and connects various data being worked to the management terminal. −
We have previously proposed a system that stores the data in a drive-type memory and analyzes the work efficiency with an analysis device such as a personal computer after the work is completed.

[0004]

By the way, in the case of the above device, the work efficiency must be analyzed exclusively by a personal computer installed in a farmer or a central management center, and a dedicated data database is used. It has the drawback that it requires softening and cannot be easily analyzed in the field. In order to be able to perform analysis in the field like a personal computer, it is necessary to install software for data base processing in the management terminal in addition to the data collection program. This is a handicap due to the complexity of the mechanical structure, which causes a costly disadvantage.

[0005]

SUMMARY OF THE INVENTION The present invention is proposed in view of the above-mentioned problems, and makes it possible to easily search and aggregate collected work data in a field or the like to analyze work efficiency. For the purpose of obtaining a data collection device that can be used, the following technical measures have been taken. That is, in a data collection device mounted on an agricultural machine and configured to transmit data on the machine side to a management terminal device via a communication line, the data collection device is set in the storage device of the management terminal device. It is configured to automatically create a data file, and the file name includes at least one of the elements of work date, machine identification code, operator name, and field number. The data collection device of an agricultural machine is characterized in that it is included.

Choose one. The corresponding one is extracted from the file list in the RAM card 29, and the corresponding one is displayed on the screen as a list. When printing this list, instruct it with the input key.When not only printing the corresponding list but also performing the totaling work, read the data of the corresponding file and add up the data. , Display the integration result. For example, the total of the distance traveled on that day, the work area, the work time of a specific worker, etc. is displayed. At this time, if necessary, the handy printer 50 may be instructed to print.

As described above, the operator searches for appropriate work data by using various searchable elements such as the work date, the field number, etc., which are incorporated in the data file name, as keys. ,
Or, since the data can be aggregated, work analysis can be easily performed in the field. Next, the flow chart of FIG. 13 will be described. The feature of the control system explained in this flow chart is that the printing function is used after collecting the work data in one field using the management terminal device and before collecting the work data in the next field. When is operated, the work data of the last field is printed. The feature is that the work data of the immediately preceding field can be printed immediately without selecting the file name.

In the figure, when the power ON switch 31 is pushed to start the data collection work, the worker inputs a header such as a work date, a model code, a machine number and the like. Immediately after the work start switch 33a is pressed, work data is sent to the terminal side, and data collection work is performed until the work end switch 33c is pressed. Work end switch 33c
When you press to enter the print menu and instruct to print, the management terminal asks if you want to select the latest file, that is, the field data just finished working, or the file before shaving. The operator selects either one and prints the field data.

FIG. 14 is a flowchart obtained by partially changing the flow shape and executing the totalization and printing of the work data described with reference to FIG. 8. FIGS. This is an example. As shown in the figure, printing is selected in the menu, and further data printing for each field or one-day data total printing for each worker or machine is selected. When you enter the work date you want to print, search for the corresponding data file on that day, and if there is a corresponding file, the field number or worker name,
Or enter the machine number. In the case of data for each field, the data of the corresponding field number is printed. In the case of totaling one day for each worker or machine, the files of the corresponding work date are sequentially read and only the data of the corresponding worker or machine number is totaled, and the total for one day is calculated. Print the results when done.
