[0017]
Furthermore, the transmission system to the left and right rear wheels 32 is provided with left and right side brakes that can be operated according to the front wheel turning angle, and the front wheel 31 is steered more than the set angle in either the left or right direction. When this is done, the side brake of the rear wheel 32 on the turning center side can be brought into a weak braking state. Thus, a technique for improving turning performance by braking the inner rear wheel 32 during turning is known as a braking turning mode.
[0018]
The controller 20 built in the control case 56 functions as the core of the ECU (electronic control unit) of the tractor, and creates various functions necessary for the tractor by hardware and / or software. . Various control devices (input devices and output devices) are connected to the controller 20. Here, only some devices suitable for the description of the present invention will be described with reference to FIG.
[0019]

[0020]
Next, as an example of a switch for inputting various control settings, regardless of the posture (tilt) of the traveling machine body, the rotary tiller 44 as an external work device equipped on the traveling machine body is set in a predetermined posture (usually horizontal). The first horizontal control changeover switch 62a, the second horizontal control changeover switch 62b, and the third horizontal control changeover switch 62c used for setting of several modes in the horizontal control maintained in the attitude) are connected to the controller 20. The first horizontal control changeover switch 62a is set to a mode in which the horizontal control is manually performed, and the second horizontal control changeover switch 62b is horizontal control on a flat ground with respect to a standard external work device (rotary tillage device 44). The third horizontal control changeover switch 62c is for setting a slope mode for performing horizontal control on a slope.
[0021]
Furthermore, the rolling UP switch 63a used for forcibly raising one side end of the rotary tiller 44 and the rolling DOWN switch 63b for forcibly lowering one side end of the rotary tiller 44 are also included in the controller 20. It is connected to the. Although not shown here, the plowing depth sensor 47, a potentiometer type position setter operated by the position lever 51, a plowing depth setter, a rolling angle setter, and a rotation operation position of the accelerator lever are measured. An accelerator sensor or the like is also connected to the controller 20.
[0022]
Among the control devices linked to the controller 20, output devices include a control display lamp and a solenoid for operating the various cylinders and brakes described above. Here, the front wheel acceleration mode described above is operating. A double speed lamp 60a for informing the driver of the above, a brake turning lamp 60b for informing the driver that the above-described braking turning mode is in operation, and informing the driver that the above-described horizontal control is in operation. A horizontal control lamp 60c is connected to the controller 20 as an example, and a horizontal control control solenoid 64, a left brake solenoid 65a, a right solenoid as solenoids for operating the rolling cylinder 46, the left and right side brakes and the front wheel transmission described above. The brake solenoid 65b and the double speed solenoid 66 are the controller 20 It is connected.
[0023]
In the controller 20, state data representing the states of various input / output devices as control devices linked to the controller 20, that is, ON / OFF values, voltage values, and the like are memories configured by a nonvolatile memory such as an EEPROM. 21 is stored in an address assigned to each device.
[0024]
This memory 21 is also used to specify a sensor when an abnormality occurs in a control device such as a sensor, and store abnormality occurrence data notifying the occurrence of the abnormality as one form of the status data of the present invention. Yes. For this reason, an abnormality check program is implemented in the controller 20 as the abnormality check unit 22. When the control is started with the engine 33 started after the key switch (not shown) is turned on, the abnormality check program checks whether the signal from the input / output device is within a normal range, for example, stroke In the case of the sensor 49, it is determined that the signal value output when the corresponding cylinder is mechanically operated for the full stroke is within a predetermined voltage range, and the signal value is outside the predetermined voltage range. It is judged as abnormal. This abnormality check program is periodically performed until the key switch is turned off. When an abnormality occurs, abnormality notification is also performed as necessary.
The device status data (including abnormality occurrence data) stored in the memory 21 can be transferred to the device status data display device 1 via the communication port 24 by the operation of the communication control unit 23 mounted on the controller 20. It is. As a data transmission connection between the controller 20 and the device status data display device 1, a cable connection form based on the RS232C protocol or the like may be adopted, or a wireless connection form based on a protocol such as IEEE 802.11 may be adopted.
[0025]
The controller 20 is also equipped with a control program for work using the rotary tiller 44. In conjunction with the control device described above, for example, at the time of automatic tillage control, the rotary program is rotated at the depth set by the tillage setting dial. A control operation is performed to drive the lift cylinder 48 by feeding back the tilling depth signal obtained by the tilling depth sensor from the swinging amount of the rear cover 44A that contacts the tilling surface so that the tilling device 44 is tilled. During automatic horizontal control, the horizontal control display lamp 60c is turned on, and the amount of expansion / contraction of the rolling cylinder 46 is obtained based on the signal from the rolling sensor 50 so that the rotary tiller 44 maintains the set ground rolling posture, and , While feeding back the signal from the stroke sensor 49 so as to expand and contract by the calculated amount, It performs a control operation to stretch the ring cylinder 46.
[0026]
When the tractor 2 including the controller 20 is maintained as described above, it is necessary to know information necessary for the maintenance, for example, the state of a control device such as a control setting switch, a control display lamp, and a solenoid. 1 is connected to the communication port 24 of the controller 20 via a cable. The main body of the device status data display device 1 is a general-purpose personal computer. As shown in FIG. 4, a communication control unit 103 and a communication port 104 that enable data transfer from the controller 101 of the keyboard 101, mouse 102, and tractor 2, A video control unit 106 that displays device information including device state data acquired from the controller 20 and arranged in an easy-to-view form on the display 105, a printer 107 that prints out such device information, and a recording medium such as an MO or a floppy And a media drive 108 for recording the data. The personal computer functions as the device status data display device 1 by loading the device status data display program according to the present invention supplied on a CD or the like to the personal computer equipped as described above.
[0027]
Among the functions of the device status data display device 1 constructed by the device status data display program, those particularly related to the present invention include the keyboard 101 as shown in the form of a schematic block diagram in FIG. An operation input processing unit 11 that determines what operation input has been performed based on a key input of the mouse 102 or a click on the mouse 102; a data acquisition unit 12 that reads out device state data from the controller 20 of the tractor 2 through the communication control unit 103; A data display screen generation unit 13 that generates information for display screens of device status data based on the read device status data, and is loaded into the device status data display device 1 in the form of an independent file as part of the device status data display program Necessary from the attribute description file 70 describing the attribute information relating to each of the above-described control devices Search and extraction unit 14 searches extract data, such as data formatting unit 15 and the like for converting the device information displayed on the display in the print output data and media writing data.
[0028]
That is, the device status data display program is a program main body as a common program part that creates functions such as the operation input processing unit 11, the data acquisition unit 12, the data display screen generation unit 13, the search extraction unit 14, and the data format unit 15. 10 and the attribute description file 70 as the dedicated program portion described above. The attribute description file 70 has a text-based file structure, and will be described in detail later, but is prepared as an independent file for each model of the tractor 2 to be maintained.
[0029]
The data display screen generation unit 13 includes a basic frame generation unit 13a that generates basic frame data and character data that constitute various display windows for maintenance device information displayed on the display 105, and read device state data. A display pre-processing unit 13b that arranges the data into an easy-to-view form, and a combining unit 13c that combines these data into display screen information for device status data.
[0030]
As shown in FIG. 5, the attribute description file 70 is divided into a prescript area, a state data description area, and a failure history description area. However, the attribute description file 70 can be created and modified while being divided into cells by spreadsheet software. Each data is described in line units separated by line feeds. As described above, the attribute description file 70 is created for each model, and the model name is adopted as the file name. In the example of FIG. 5, the attribute description file 70 used for the model “King” has a file name of King.ini (ini is an extension). Therefore, when displaying a list of applicable models, the file names may be displayed as a list.
[0031]
As apparent from FIG. 5, the prescript area includes a communication protocol for data transmission with the controller 20 of the corresponding tractor 2, a failure history format indicating a storage format of the failure history stored in the memory 21 of the controller 20, The address range storing the device status data of the EEPROM constituting the memory 21 is described. When the attribute description file 70 is created or modified, the device status data is simply written in the form of “item name =...” In the line below each item using spreadsheet software or a text editor. The program main body 10 of the display program can extract and use necessary data from the text data described in the line below the item name. For example, if the EEPROM address range is “0,127”, data dump display is possible by reading data from address 0 to address 127.
[0032]
As shown in FIG. 6, in the status data description section, attribute information including a plurality of field items of each control device is delimited by a line feed code, that is, described as a record in units of lines. The field items include a record number, device name, function classification, storage address, mask data, category 1, category 2, unit, proper judgment criterion, and remarks. Here, the name of the device is an easy-to-understand name of the input / output device whose state data is stored in the memory 21 of the controller 20, for example, “first horizontal SW”, “rolling sensor”, etc. The function classification describes the name of function control in which the device is used. By using this function classification as a search key, it is possible to extract only the attribute information related to the device related to the specific function control, which is convenient when displaying status data for each specific function control. The storage address is an address of the memory 21 in which the state data is stored, and the corresponding state data can be acquired by requesting data transfer to the controller 20 using this address as an argument. The mask data is used to extract only the corresponding status data when the data transferred from the corresponding address includes the status data of a plurality of devices in bit units. The mask data is ANDed with the transfer data. It will be calculated. Category 1 classifies whether the corresponding device is an input system or an output system, which is convenient when displaying status data separately for an input system and an output system. Category 2 indicates the type of data. For example, “BIN” represents binary data, and AD10 represents voltage data representing 5 V in 10 bits. In the unit, a unit symbol when the state data has a unit is described. When the state data transferred from the memory 21 is simply displayed numerically, there are cases where the unit is amperage, volts, or an expert. In such a case, by displaying the unit symbol read from the unit field together with the numerical value of the state data, a more user-friendly display is realized. Finally, the appropriate criteria used to determine whether the transferred status data is correct are also described in some cases. It is also possible to draw the user's attention by using colors or flashing.
[0033]
The failure information description unit is used when displaying the failure data written in the address of the memory 21 given in advance to the control device determined to be abnormal by the abnormality check unit 22 of the controller 20 while the tractor 2 is in operation. Attribute information to be described is described, and as shown in FIG. 7, the description information is similar to the state data description portion. By retrieving and extracting only the records described as “ERR” in category 1 from the device attribute description file 70 of the corresponding model, it is possible to obtain attribute information such as a memory address related to failure occurrence data. Further, here, it is defined that if the value of the state data (failure occurrence data) acquired from the designated address of the memory 21 is “0”, it is regarded as a failure if it is “1”.
[0034]
Next, the procedure for displaying the status data of the control equipment equipped in the tractor 2 using this equipment status data display device 1 is shown in the display of this equipment status data display device 1 shown in FIGS. This will be described with reference to the display screen diagram displayed in 105.
[0035]
When the program body 10 of the device status data display program loaded in the device status data display device 1 is activated, a maintenance model selection screen as shown in FIG. 8 is displayed. This screen is composed of input frames having items such as model name, model name, and serviceman name. This portion is created by the basic frame generation unit 13a of the data display screen generation unit 13. However, for example, each item of a so-called pop menu displayed in the model name selection area has all attributes loaded in the device state data display device 1 extracted by the display preprocessing unit 13b via the search extraction unit 14. It consists of the file name of the description file 70. When three attribute description files 70 as shown in FIG. 5 are loaded, “King”, “Queen”, and “Prince” are displayed in this pop menu. Of course, when another attribute description file 70 is added, the file name is also added to the pop menu. That is, the program main body 10 is left as it is, and an attribute description file 70 for the new model is added as the new model appears, and the new model name is added to the pop menu.
[0036]
When an appropriate model is selected on the maintenance model selection screen in FIG. 8 and the “Next” button is clicked, an item selection menu screen as shown in FIG. 9 is displayed. On this screen, when an input / output check item is checked and a “Next” button is clicked, an input / output check general screen as shown in FIG. 10 is displayed. Here, when the “Save” button is clicked, it is transferred from the controller 20 of the tractor 2 regarding the selected item, that is, any of input / output check, ECU basic information, failure information, or a combination thereof. The state data is processed by the display preprocessing unit 13b based on the attribute information recorded in the attribute description file 70, transferred to the data format unit 15 together with necessary attribute information, arranged in a predetermined layout, and then processed by the media drive 108. It is stored in a predetermined recording medium. Similarly, when the “print” button is clicked, the above-described status data and attribute information associated therewith are printed out by the printer 107 in a predetermined print style.
[0037]
In this input / output check general screen, the basic layout configuration is created by the basic frame generation unit 13a, but the screen pre-display processing unit refers to the contents of the attribute description file 70 to create the screen of information representing the state of each control device. 13b. In other words, here, the attribute description file 70 of the model to be checked is read into the working memory and sorted using the values of category 1 and category 2 as keys, so that the input device group whose state data is a voltage value is obtained. An input device group that is listed in the first display field and that has switch data (binary data) whose status data is ON / OFF is listed in the next display field, and the status data is the rotation speed. The output speed of the engine speed sensor 66 is listed.
[0038]
If the items listed in each display column cannot be displayed, these items are scrolled, but the category display buttons located in the upper left of each display column, here "Voltage" button, "Switch input" By clicking the button, “Output” button, all items listed in each display field are displayed in the input / output check individual screen as shown in FIG. 11 and FIG.
[0039]
In the display column of the input device group having a voltage value as the status data, as shown in FIG. 10 and FIG. 11, the status data is shown in a box arranged on the right side of the sensor name as the name of the corresponding control device. As a unit, “V” as a unit on the right side, and a value of an appropriate measurement standard. In addition, a button is placed on the left side of the sensor name. If the status data of the corresponding sensor, that is, the voltage value is out of the proper measurement standard, it is red as a failure, and if it is within the proper measurement standard, it is blue as normal. Is displayed.
[0040]
On the other hand, in the display column of the input device group having ON / OFF binary data as the status data, as shown in FIG. 10 and FIG. 12, the sensor name as the name of the corresponding control device, and the sensor name Only the buttons arranged on the left side are displayed, but the color of each button is used to indicate the ON or OFF state of each sensor. Here, blue represents ON and yellow represents OFF. .
[0041]
When a check mark is entered in the item of failure information on the item selection menu screen in FIG. 9 and the “Next” button is clicked, the abnormality check unit 22 of the controller 20 as shown in FIG. A failure information screen listing the control devices determined to be abnormal by the above-described acquisition of the failure occurrence data is displayed.
[0042]
In any case, the display screen data displayed on the screen should be requested by the data acquisition unit 12 to transfer data to the controller 20 with the value of the “address” field extracted as the content of the record of the corresponding control device as an argument. The display value and the “name” field value obtained by processing the data acquired in the above processing by the display preprocessing unit 13b based on the value of the “mask data” field and the value of “category 2” are combined with the combining unit 13c. Created by incorporating into the basic display frame created in
[0043]
FIG. 14 illustrates a procedure for displaying the state data of the various control devices described above on the display 105 in a manner that is easy for the user to understand, taking up state data of the rolling sensor 50 as one of such state data. To do.
First, the model selected using the mouse 102 on the maintenance model selection screen in FIG. 8 is internally processed by the operation input processing unit 11, and “King.ini” is obtained from the attribute description file 70 prepared for the number of models. The search extraction unit 14 extracts a record that matches a predetermined search condition from the loaded attribute description file 70. It is assumed that a record with a record number 11 is extracted therein. The most important field in the record is a field representing the address of the memory 21. In this example, “30H40” is extracted and sent to the data acquisition unit 12 and used as an argument of the data request function to the controller 20 to acquire the data. Unit 12 receives raw state data as a response to this function. The display preprocessing unit 13b recognizes that this raw state data is voltage data representing 5V in 10 bits from "AD10" which is the field value of category 2, and converts this into a decimal value. For example, “1.18” is obtained. The unit field value “V” is used as the unit. Further, the display preprocessing unit 13b checks whether the value satisfies the criterion described in the appropriateness criterion field, and if satisfied, the color of the item button created by the basic frame generation unit 13a is green. If you are not satisfied, specify red. Furthermore, the name of this state data, here “rolling sensor” is taken out and sent together with the above-mentioned data to the synthesizing unit 13c, as display data on the display 105, as a basic frame including a button (image) and character data. “Rolling sensor 1.18V 0.20 to 4.90” (see FIG. 14) is generated. Similarly, the status data of other control devices is also the display data as described above.
[0044]
What is important in the description with reference to FIG. 14 is that a device status display program that accesses the controller 20 to read the status data of the control device, converts it into a format that can be easily understood by the user, and displays it on the display 105 is an operation input. It consists of a basic program part that creates functions such as the processing unit 11, data acquisition unit 12, basic frame generation unit 13a, pre-display processing unit 13b, synthesis unit 13c, and the like, and an attribute description file 70. Since the part depending on the device is described in the attribute description file 70, even if a new model appears, it can be dealt with by only creating a new attribute description file 70. In addition, even if the specification is changed in the same model, it can be dealt with only by changing the contents of the corresponding attribute description file 70.
