The liquid crystal monitor 3 is configured as a touch panel, and is configured such that an operator directly presses display items displayed on the monitor 3 with his / her finger to select various items or switch screens.
The display on the monitor 3 shown in FIG. 1 is a screen in which "tractor" is selected in a "machine" mode described later, and is displayed together with other display items of a general work vehicle such as a vehicle speed, a traveling distance, and an engine speed. , And information specific to the tractor, such as the tillage value, is displayed in a predetermined format.
In addition, in the display of the monitor 3, in addition to the "machine" mode, a "field information" mode for displaying information for each field, and an "internet browser" mode for displaying weather information and various news, for each display mode. A display window is set, and the screen is switched by pressing a tab portion below the display window.
On the other hand, as shown in FIG. 2, a tractor T serving as a work vehicle is provided with a meter panel 21 in front of a steering handle 20 and a vehicle connected to the connector 15 of the management terminal 10 on a side of the meter panel 21. A side connector is provided, and the management terminal 10 is attached.
Thereby, the operator can compare the vehicle information displayed on the meter panel 21 of the tractor T with the various information displayed on the management terminal 10 and perform an operation.
Further, on the side of the cockpit 22 of the tractor T, various setting devices 23... And an operation lever 24 are provided to control the set values of these setting devices 23, the operation position of the lever 24, and the position information of a control drive unit such as a lift arm. The configuration is such that the data is transmitted to the controller C constituting the unit.
Next, the internal configuration of the management terminal 10 and the configuration of the controller C of the tractor T will be described with reference to FIG.
The management terminal 10 processes input / output information and processes the map data according to the present invention. The CPU 7 and various storage devices, specifically, a navigation control program, processed map data, and various information added thereto. And an RAM 6 for temporarily reading and storing various sensor values and control programs.
The input unit is provided with a GPS receiver 30, a gyro sensor 31, the power ON / OFF switches 11 and 12, and a touch panel operation unit 3b connected thereto.
The output section is connected to the liquid crystal monitor 3a, the speaker 33, and the like.
The management terminal 10 further includes a communication interface 1 serving as a communication unit with the controller C of the vehicle, and an external device interface 5 for reading data stored in the DVD-ROM 13.
In the management terminal 10, the map data 4 stored in the DVD-ROM 13 is read. However, if the map data is stored, another storage medium, for example, a stick-shaped storage device or An additional hard disk may be used.
Similarly to the management terminal 10, the controller C of the tractor T also has a CPU 35 for processing input / output information, an EEPROM 36 for storing various control programs such as tillage depth control, and various programs and sensor information. It has a configuration including a RAM 37 for storing.
The input unit is provided with, for example, various sensors 40 and setting devices 23 in addition to the tillage depth sensor 38 and the lift arm angle sensor 39 used for the tillage depth control.
The output unit includes, for example, solenoids 41 and 42 of control valves for raising and lowering the working machine for operating the lift arm, various actuators 43, a pilot lamp 44, and a vehicle-side liquid crystal monitor 45. Are connected.
In the management terminal 10 configured as described above, map data processing control is performed as shown in FIGS.
First, when the power is turned on by the power ON switch 11, the management terminal 10 calculates the current position from the GPS receiver 30 and reads the map data 4 from the DVD-ROM 13 (STEP 1-2).
Then, the display mode of the monitor 3a is determined, and more specifically, which tab below the window screen is selected is determined. If this is the tab indicating the machine name such as "combine" or "tractor" is selected. For example, the mode is determined to be the "machine" mode, the process proceeds to STEP4, communication with the controller C of each machine is performed, and vehicle information is displayed on the monitor 3a.
Further, the sensor information of the vehicle obtained in the “machine” mode is automatically input as data for the entire field or for each section of the field in the “field information” mode described later. For example, if the total discharge amount of the paddy obtained by the combine operation is input as the harvest amount of the entire field. Further, if the detected value is a tillage depth sensor obtained by the operation of the tractor T, the tillage depth is automatically recorded as a tillage depth value for each field section. Further, in the case of an agricultural work vehicle provided with a steering angle sensor on the handle 20, if a rapid steering operation at a certain angle or more is detected during work traveling, it is determined whether there is an obstacle in the field on the monitor 3 on the monitor 3. If there is an obstacle, select this type and set a specific mark (M1 in the figure, grove, M2: telephone pole) on the map of the field.
If the display mode is selected to the "navigation" mode, as shown in FIG. 9, the map data of the DVD-ROM is displayed on the monitor 3a, and based on the GPS receiver 30 and the gyro sensor 31, And the position of the field are displayed (STEP 5).
When the vehicle travels in the field in the “navigation” mode, the navigation in the field is performed based on the information of the field processing map that has already been created. Specifically, as shown in the display section of the field in FIG. 9, when traveling in the rice field B by combine, the planting direction of the seedlings is stored during past rice planting work, and the work route of the combine is displayed. It has a configuration. Thereby, even when an inexperienced operator works, or when an operator different from the planting operation is operated, useless traveling is eliminated, and work efficiency can be improved.
Also, if obstacles such as trees and muddy grounds or telephone poles are set in the course of the past in the past work, a warning or a speaker is sounded in advance to call attention, or with the controller C on the vehicle side. The vehicle speed is automatically reduced by the communication of the vehicle, or the steering wheel is turned by an actuator to change the course.
Thus, even when an inexperienced operator works on the field, it is possible to prevent the vehicle from coming into contact with obstacles or the like hidden behind crops, thereby preventing damage to the vehicle body and equipment.
If the display mode is set to the “field information” mode, the process proceeds to STEP 6 and the operator waits for an operation of selecting a specific field shown on the map. When this is completed, the data of the field is already stored. It is determined whether or not it has been set (STEP 7). If this is YES, the already set information is displayed on the monitor 3a.
On the other hand, if the determination in STEP 7 is NO, the outline of the field is fetched from the map data 4 and the partition setting processing is performed in STEP 9. Thereafter, the additional information is stored in the EEPROM 6 together with the field number.
Next, a control program of the section setting process will be described with reference to FIGS.
In the section setting process, first, the outer shape of the selected field is displayed, and guidance for designating the entrance of the field is displayed. When the entrance is designated, partition the standard from the entrance, where a square of 1 m 2 partition is set (STEP3). At this time, if there is an area that does not fit into the standard section, such as the end of the field, it is configured to be stored separately as a deformed section (STEPs 4 to 6).
Then, after the section is set in the processing of STEP 7, the result is displayed, the operator waits for the confirmation operation by the operator on the confirmation screen, and when the operation is completed, the state becomes END.
Next, a control program of the data manual input process will be described with reference to FIG.
The data manual input process is for manually inputting or correcting various information on a map in the field where the section is set.
In this process, first, the operator waits until a specific field is selected from the map data 4 by the operator, and when this is completed, displays the field set as a section. Then, various data is input for the entire field, for each section, or for the section range. In detail, the data to be set for the whole field is the owner, area, etc., and the data to be set for each plot of the field is the type of planted crop, the planting direction, the number of planted plants, the presence or absence of withering, the latest It is configured to set crop information such as the growth status of the vegetation, positional information of obstacles such as telephone poles, trees and irrigation blocks, and tillage depth and fertilizer application amount.
In the data setting operation, when one field is selected on the touch panel 3b, as shown in FIG. 9, a grid-shaped field divided into fields and setting items are displayed.
After that, the whole field, the section, or the section range is designated at a time, the setting item is selected, and character information or numerical information is input by an input key screen displayed separately. For example, in the case of character information such as the name of the planted crop, the name of the crop is input with a character input key, and in the case of numerical information such as the tillage value, a numerical value is input with a numerical input key.
Thereafter, after the confirmation screen is displayed, when the confirmation operation by the operator is completed, the data, that is, the information set for each field or each section is stored in the EEPROM 6.
The management terminal 10 configured as described above can use the external map data 4 to refer to local map data in the field together with information on the surroundings of the field. Regardless, anyone can work efficiently. In addition, since data only for the required fields is created and stored, the data storage capacity mounted on the management terminal 10 can be reduced as much as possible, and the production cost can be reduced.
Further, since the external map data 4 is sectioned and information is added for each section based on vehicle-side sensor information such as the running state or the working state of various agricultural work vehicles such as tractors, input operations by the operator can be reduced. In addition, an accurate field map can be created.
In addition, since the portable management terminal 10 can be attached to a plurality of types of machines, it is possible to know the past work state, and as described above, anyone can work efficiently regardless of the operator's experience or land review. .
Incidentally, as another form of the management terminal device 10, the "machine" mode, the "navigation" mode, and the "field information" mode are simultaneously processed by the CPU, and the information is appropriately recorded without switching the screen, It may be configured such that it guides the inside of the field and corrects each time. Further, the management terminal 10 and the controller C of the agricultural work vehicle may be divided into a plurality of parts according to their respective roles, and information may be transmitted and received between them by communication.
Further, as the machine to which the management terminal is attached, the installation type machine related to the work, for example, in the case of rice cultivation, it is configured to be able to communicate with a controller such as a drier or a huller, and the harvest amount and the growth status of the paddy in the entire field. It is also possible to adopt a configuration in which the setting amount, the drying time, or the roller adjustment of the huller are automatically set accordingly.
Further, the storage device provided in the management terminal 10 may be a detachable storage device that can be shared with home appliances and various information devices.
Next, an installation type work management device (hereinafter, work management system 9) composed of a personal computer PC and the auxiliary devices H1, H2,... Will be described with reference to FIG.
The description of the same configuration as above is omitted.
Here, at least a GPS receiver and a gyro sensor are provided on the working machine side such as the tractor T, and a communication modem 47 connected to the work management system 9 via a wireless telephone line and the Internet is provided. It is configured to store information transmitted from the work management system 9 or weather information on the Internet. The information received by the modem 47, that is, the information in the machine mode, the field mode, or the navigation mode is displayed on the existing monitor 45.
The work management system 9 includes a personal computer PC having a monitor, a keyboard, and a mouse, a hard disk H1 storing the map data 4, a communication modem H2 for communicating with the controller C of various work vehicles such as the tractor, and the like. Is configured to include a printer H3 capable of printing out various data as a list or as data for each field.
In the work management system 9 configured as described above, similarly to the above, the outer shape of the field is extracted from the map data 4 stored in the DVD-ROM, and a section is set for this outer shape. The sensor value transmitted from the controller C is automatically added as the whole field information or the section.
Further, the processed data can be manually input and corrected from a keyboard, and the processed data is stored in the hard disk H1.
As a result, the map information of the field can be centrally managed, and the efficiency of the work can be improved as described above, and the operation cost can be reduced when the work is performed in a group such as a corporation.
