According to a second aspect of the present invention, the control device includes a determination unit (B) for determining whether or not the component specific information stored in the storage device (A) matches the newly read component specific information. The vehicle control device according to claim 1, further comprising:
(Operation of claim 2)
In the control device of the vehicle body (1), when the stored component specific information matches the newly read component specific information, for example, a notification of “conformity” is given, and if they do not match, a notification of “nonconformity” is given. To do.

  In short, in claim 1, the vehicle body (1) is stored in the storage device (A) for storing unique information such as the product number including the product type and the IC tag (21) provided in the detachable component (4). A reading device (26) for reading the unique information, and the component unique information registered in the storage device (A) can be confirmed on the display (24). Even if they are mixed, it is possible to install parts without error and improve the efficiency of inspection and replacement work.

  Further, in claim 2, since the control device of the vehicle body (1) determines whether or not the replacement part is appropriate, the operator who performs the inspection and replacement work does not need to memorize the combination of the vehicle body and the part accurately, The burden can be reduced.

A riding tractor equipped with the present invention will be described below with reference to the drawings.
FIG. 1 shows a side view of a tractor. This tractor has an engine E mounted in a bonnet 2 at the front of a vehicle body 1, and the rotational power of the engine E is transmitted to a transmission in a mission case 3. The rotational power decelerated by this transmission is transmitted to the left and right front wheels 4, 4 and the left and right rear wheels 5, 5.

  In addition, a cabin is mounted on the mission case 3, and a control space is configured by including a cockpit 8, a steering handle 6, various setting devices and an operation tool 12 in the cabin. A controller 20 is provided below the cockpit 8 as a control means.

  In addition, a hydraulic cylinder case 9 is provided at the upper part of the transmission case 3, and lift arms 10, 10 are pivotally attached to the left and right sides of the hydraulic cylinder case 9. The hydraulic cylinder case 9 is internally provided with a hydraulic lifting cylinder 11 for moving up and down various working machines (rotary working machine R in the illustrated example). When hydraulic oil is supplied into the hydraulic lift cylinder 11 via the lifting electromagnetic valve, the lift arm 10 is turned up, and when the hydraulic oil in the hydraulic lift cylinder 11 is discharged via the lowering electromagnetic valve, the lift arm 10 is lowered. It is designed to rotate. Reference numeral 12 denotes a hydraulic lift lever that moves the lift arms 10 and 10 up and down. The rotary work machine R is connected to a vehicle body via a so-called three-point link mechanism including a top link 16 and a lower link 17, and the lift arm 10 and the lower link 17 are connected by a lift rod 18.

  Further, as shown in FIG. 3, a meter panel 23 is provided on the handle column 7 in front of the steering handle 6. The meter panel 23 has various pilot lamps 39 and a liquid crystal monitor (display) 24. Furthermore, on the column below the meter panel 23, a communication device (corresponding to the reading device of the present application) 26 for reading information on the IC tag 21 and writing various information depending on the situation, and a screen of the liquid crystal monitor 24 are displayed. The display changeover switch 14 for switching is provided. Further, a working machine lifting / lowering one-touch lever 13 for operating the working machine up and down is projected from the upper side of the column 7 and a horn 40 is provided at the lower part of the column 7.

Next, the configuration of the controller 20 will be described with reference to FIG.
The controller 20 includes a CPU for processing various types of information therein, a storage device (EEPROM) A for storing component information in the IC tag of the present invention, and a control program B serving as means for determining the suitability or nonconformity of these pieces of information. It is the structure provided with ROM etc. which stored.

  When registering the information stored in the IC tag 21 with the tractor configured as described above, the IC tag 21 provided in various components is brought close to the communication device 26. Then, the component specific information stored in the IC tag 21 is read by the communication device 26 and displayed in order on the liquid crystal monitor 24. Thereafter, the component specific information is stored in the storage device A of the controller. Specifically, the data file area subdivided for each component is selected and registered in accordance with the guidance of the monitor 24.

  In addition, as shown in FIG. 4, the data file in the storage device A includes information divided into a fixed area and a variable area for each part provided in the tractor, for example, for each wheel on the left and right, front and rear, or for each of various work machines. It is the structure registered to. In the fixed area, for example, information such as parts classification, manufacturer, product type, serial number, date of manufacture, etc. that cannot be arbitrarily changed by the operator is stored, and in the variable area, for example, owner, purchase date, price, Information that can be arbitrarily changed by the operator, such as usage time, is configured by inputting various switches permanently installed on the vehicle and an external communication device having an input key to the controller 20.

  When the combination of parts is collated by the tractor, the IC tag 21 of the part to be mounted is brought closer to the communication device 26. As a result, the control program in the controller 20 determines whether or not information that matches the manufacturer, manufacturing model, and manufacturing number is stored in the storage device A among the read information. If there is something, “appropriate” is displayed on the liquid crystal monitor 24. If there is no coincident information, a message prompting “improper” or “new registration” is displayed on the monitor 24.

  As a result, the operator determines whether the part is a part registered in the vehicle body at the time of inspection or replacement work, that is, whether the combination of the vehicle body 1 and the part matches, and an incorrect part is mounted. Can be prevented.

  In addition, by attaching the IC tag 21 to which this component-specific information is input to the machine, it is possible to read the IC tag 21 when the label such as the model is peeled off and lost, and the past repair history, etc. If it is entered, it becomes easier to investigate the cause of the failure, and if the owner is registered, theft can be prevented.

  The IC tag 21 self-transmits information stored in response to electromagnetic waves sent from the communication device 26. When this IC tag is attached to the part to be replaced, for example, the part is shown in FIG. In the case of using a wheel (front wheel 4 or rear wheel 5) as shown in FIG. 4, if a concave portion 25a is formed inside the wheel 25 and the IC tag 21 is attached inside the concave portion and covered with the vehicle body side parts, Corrosion and wear due to the above can be prevented and the durability of the IC tag is not impaired, and it is difficult to remove even if it is stolen.

  In the control block diagram shown in FIG. 2, on the input side of the controller 20, an input key switch 30 for starting the engine, a steering angle sensor 31 for detecting the steering angle of the vehicle body, and the height of the work implement are set. Working machine lifting / lowering potentiometer 32, Raising position setter 33 for setting the working machine lift height, Lift arm angle sensor 34 for detecting the working machine height, Rolling control mode for setting various rolling control modes of the working machine A setting device 35, a tilt adjustment dial 36 for manually adjusting the tilt of the work implement, a tilt setting switch 37 for setting the tilt to be held, a slope sensor 38 for detecting the left / right tilt angle of the vehicle body, and the like are connected. On the output side, various pilot lamps 39 on the meter panel 23, a horn 40, a solenoid valve for raising and lowering the work machine De 41a, 41b, solenoid 42a of the telescopic control valve for rolling cylinders, 42b, etc. are connected. Reference numeral 43 denotes a connector serving as a connection means with an external communication device.

  Next, based on FIG. 6, an operation procedure for initializing the component specific information of the IC tag stored in the storage device A of the tractor will be described. Conventionally, in this data initialization operation, after the mode switch provided separately was turned on and the engine input key was turned on, an unfamiliar operator inadvertently turned the mode switch on. There was a risk that the engine would start and the various information would be erased.

Therefore, here, after turning on the power of the electrical system of the tractor, the guidance is displayed on the liquid crystal monitor 24, and the IC tag information is initialized according to this guidance.
Specifically, when the input key switch 30 of the engine is turned on to turn on the electrical equipment, a guidance screen for selecting a normal (operation) mode and a maintenance mode is displayed. Then, when this maintenance mode is selected and items are determined according to the following guidance, data is initialized.

  The item selection operation is performed by turning on the raising switch 13a or the lowering switch 13B of the lever base by raising or lowering the one-touch lever 13 for raising / lowering the work machine projected from the side of the handle column 7. In addition, the item is determined by switching the display screen to the next screen by turning on the display changeover switch 14 at the top of the column.

  The symbol M in the screen is a mark indicating that the display item is hidden below the monitor screen. By turning on the lowering switch 13b of the lever 13, the screen is scrolled downward line by line. By turning on 13a, it is configured to scroll upward line by line.

  The sensor reference value mode on the guide screen is a mode for setting the neutral position when various sensors and dial type setting devices are exchanged, and this also operates each member according to the guide screen to change the switch 14. The configuration is determined by switching the monitor screen.

  FIG. 7 shows another form of the control means, in which the single controller 20 is divided into a plurality of controllers 20a, 20b,... According to various controls, and these controllers are connected by a CAN line 53 to share various information. It is configured.

  In this case, a “controller check mode” is provided in the maintenance mode, communication is performed between the controllers 20a to 20d in this mode, a controller that cannot communicate within a predetermined time is determined to be defective, and the LCD monitor 24 It is configured to display.

  Conventionally, the main function of the maintenance mode is to check individual sensors, but there are many problems with the controller itself in workplaces where vibrations and temperature differences are severe. For example, if one controller is defective, In many cases, a controller failure is found while searching for the cause of the sensor trouble, and a great deal of time is spent at the time of shipping inspection.

  In the “controller check mode” of this example, the controller 20a for the meter panel diagnoses whether each controller, for example, the controller for work implement attitude 50b and the controller for traveling parts 50c is normal through communication, and is set in advance. When communication is performed, the controller is determined to be “normal”, and a controller having a communication failure or no response is determined to be “bad”, and the “bad” controller is displayed on the liquid crystal monitor 24. Thereby, as described above, the trouble of the sensor and the trouble of the controller itself can be immediately discriminated, and the man-hours for maintenance can be greatly reduced.
