DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below.

FIG. 1 is a block diagram of the entire data acquisition system. Reference numeral 1 in the same figure is a control device for an agricultural machine (for example, a tractor), and this control device 1 is responsible for overall control of the traveling unit and each operating part. Signals from the various sensors 2, ..., Operation switches 3, ... And setting devices 4, ... Are input to the CPU 7 through the input interface 6, and based on the input signals, the CPU 7 outputs the motor through the output interface 9, An output signal is output to the actuator 10 such as a solenoid or a valve. Required input information and output information are display devices such as meters and lamps 1
It is displayed in 1.

The vehicle speed sensor 2A and the fuel flow rate sensor 2B among the sensors generate sensor pulses according to the instantaneous value of the vehicle speed or the fuel flow rate, and the sensor pulse count number n ₁ within a fixed period T. , N ₂ , ...
Is transmitted to the CPU 7 with a communication pulse (see FIG. 2).

Other sensors include a lower link sensor, a lift arm angle sensor, and a horizontal sensor in the case of a tractor, and a cutting width sensor in the case of a combine. Since these sensors are DC detection signals, the detection signals are converted by the A / D converter 13 and then input to the CPU 7.

Reference numeral 20 in FIG. 1 denotes a data collection device (management terminal device), which is used by being connected to the control device 1 so as to be communicable. The data collection device 20 includes a CPU 21 and an operation unit 2.
2, a display unit 23, a RAM 25, a Chinese character ROM 26, and the like, a main body 20a, and a ROM card 28 and a RAM card 29 as memory means that are selectively attached to the main body. The ROM card 28 individually stores control programs for each model and model of the agricultural machine. It is convenient to record a control program common to all models in the ROM card 28 because the versatility is improved. Further, the RAM card 29 can record data for each predetermined item. FIG. 9 shows an example of data items.

Even if the ROM part and the RAM part of the memory means are recorded in separate memory cards as in this embodiment, the ROM part and the RAM part of the memory means are recorded in a common memory card. You may keep it.

The data collection device 20 is shown in, for example, FIGS.
It has the appearance as shown in. On the front of the box-shaped main body 20a, an ON / OFF switch 31 as the operation unit 22,
32, operation switches 33, ..., Input keys 34 ,.
Insertion ports 36 and 37 for the card 28 and the RAM card 29
And a printer connector 38.

Communication between the control device 1 and the data collection device 20 is performed via the communication interfaces 40 and 41. The illustrated example is a method by optical communication, in which the optical interface 41 is provided on the bottom surface of the mounting groove 43 of the main body of the data collection device, and the communication interface unit 44 (illustrated in FIG. 6) on the control device side is provided. Is also provided with a similar optical interface. When the data collecting device main body 20a is attached to the communication interface unit 44, both optical interfaces face each other, and information can be exchanged between both devices. By performing the optical communication in this way, there is an advantage that the data collection device 20 can be easily attached to and detached from the agricultural machine, is not easily affected by vibration, and can perform good communication without noise.

When the agricultural machine is a tractor, for example, as shown in FIG. 7, if the communication interface unit 44 is attached to the center pillar 46 in the cabin 45, the data collecting device 20 while sitting in the cockpit is provided.
It is convenient because you can perform the operation.

The operation method of the data collection device 20 will be described below. (See Figure 8).

When the data collecting device 20 is attached to the communication interface unit 44 and the ON switch 31 is pressed (power ON), communication between the data collecting device 20 and the control device 1 is started. If the communication status is good, it is first checked whether the control program stored in the ROM card 28, which is the ROM portion of the memory means, matches the actual model and model of the agricultural machine. This confirmation operation is performed by transmitting a connection confirmation command from the data collection device 20 to the control device 2.

If the control program matches the model and model of the agricultural machine, the field No. Is input using the input keys 34, .... This is the case according to the data items in FIG. Instead of customer number. And worker N
o. You may enter. In short, it can be any one that is convenient for identification.

Subsequently, the control device 1 to the data collecting device 2
The vehicle speed conversion coefficient a ₁ and the fuel flow rate conversion coefficient a ₂ are transmitted to 0. a ₁ and a ₂ are coefficients set for each model and model of the agricultural machine, and are multiplied by the number of detection pulses of the vehicle speed sensor 20A and the fuel flow rate sensor 20B to be converted into the instantaneous values of the vehicle speed and the fuel flow rate. It These conversion factors a ₁ and a ₂ are stored in the RAM 25 until the end of work.

After the above operation is completed, the start switch 3
When 3A is pressed (start SW is ON), the start time is recorded and displayed on the liquid crystal display unit 23 as shown in FIG. At the same time, transmission of the pulse numbers n and m of the vehicle speed sensor and the fuel flow rate sensor is started. During work, these pulse numbers n and m are successively added.

Press the end switch 33B (the end SW is O
N) and the integrated value l of the vehicle speed pulse are multiplied by the conversion coefficient a ₁ to calculate the traveling distance L, and the integrated value w of the fuel flow rate pulse is also multiplied by the conversion coefficient a ₂ to calculate the fuel consumption amount W. The obtained traveling distance L and fuel consumption amount W are recorded in the RAM card 29 which is the RAM portion of the memory means,
Further, the end time is also recorded in the RAM card 29, and all the collected data are displayed on the liquid crystal display unit 23 as shown in FIG.

Further, when the work is interrupted due to meals or the like, if the interruption switch 33C is pressed, the work data being collected can be kept in a suspended state even if the agricultural machine is stopped. When restarting the work, the interruption switch 33
When C is pressed again, the data collection work is restarted. In addition,
I intended to suspend the work temporarily, but for some reason I could finish the work of the day as it is, so there is an automatic end function that automatically closes the data file after a certain period of time in the suspended state. You should keep it.

As described above, since the sensor information of the agricultural machine is received and necessary work data is calculated, the accuracy of the obtained work data is extremely high. Further, since the predetermined conversion coefficient determined for each model and model of the agricultural machine is transmitted to the data collection device 20 in advance, and then the sensor information is transmitted, various data collection devices 20 can be used. It can be shared with other agricultural machines.

The sensor that receives information in this data collecting device is a type of sensor that transmits information by pulse signals. As this type of sensor, in addition to the vehicle speed sensor and the fuel flow rate sensor, a chemical spray amount sensor, etc. There is. Moreover, it goes without saying that the agricultural machine can be used not only as a moving machine such as a tractor and a combine machine but also as a stationary machine.

FIG. 6 is an explanatory diagram of the management system, in which the handy printer 50 is connected to the printer connector 38 of the data collecting device 20 and the obtained work data can be directly printed on the recording paper or the PAM card 29. The recorded data can be read by the memory card reader 51, input to the personal computer 52, and the work data can be printed on the printer 53 connected to the personal computer 52.

Further, the communication interface unit 44
The work data can be directly input from the data collection device 20 to the personal computer 52 by connecting the communication interface unit to the personal computer 52 so that the work can be detached from the agricultural machine.
