Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a method for changing, for example, a standard operation program for loading operation to an optional operation program among operation programs for causing a garbage truck to perform loading or discharging operation, for example.
[0002]
[Prior art]
The garbage truck can execute a loading / unloading operation, for example, by an operation program read from the memory ROM by the controller. Therefore, in the memory ROM, a standard operation program and an optional operation program corresponding to the standard operation program are stored in advance for each of the plurality of operation programs executed in the garbage truck. Of these operation programs, for example, a user may be required to change a standard operation program for a loading operation to an optional operation program. One such change method is proposed in Japanese Patent Application No. 2001-334229 of the present applicant.
The proposed change method is that when the standard operation program for loading operation described above is changed to an optional operation program, operation of the loading button, reverse button, push button, etc. provided on the operation panel is performed. By operating predetermined operation buttons among the buttons in a predetermined order according to a predetermined operation method, the read command value of the standard operation program for loading operation written in the internal memory of the controller is It is rewritten to the read command value of the option operation program, and the program is changed.
[0003]
[Problems to be solved by the invention]
However, in the change by the predetermined operation method by the combination of the predetermined operation buttons as described above, either the standard operation program or the optional operation program can be selected as in the above-described loading operation, and further, it can be selected. When there are many optional operation programs, it becomes too complicated, and it becomes easy to make mistakes in pressing the operation buttons and the operation method, so that there is a problem that it is not usable and is not practical. Further, depending on a mistake in pressing the operation button, a situation may occur in which the operation program for the operation button is executed.
Further, since it can be changed as long as it knows how to operate the operation buttons, the operation program cannot be completely disabled by the user.
[0004]
An object of the present invention is to provide a method for changing an operation program of a garbage collection vehicle that is simple and practical without any trouble.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a method for changing an operation program of a garbage collection vehicle according to claim 1 of the present invention is a standard operation for each operation program such as loading or discharging operation executed in the garbage collection vehicle. comprising a memory ROM option operation program for different control is stored in advance in the program and the normal operation program is read by the controller from the memory ROM, the optional operation standard operation programs such as the loading or discharge operation A method of changing a program to a program, wherein a memory holding type memory is provided in a main body of the controller, a read command value for selecting an operation program is stored, the memory ROM is removed, and the standard operation program of the controller The read command value of Attach the rewrite ROM for rewriting the read command value ® down operation program is obtained by allowing a program change by rewriting the read command value by operating the ROM.
This change method is different from the conventional method using a combination of operation buttons and the method of operation thereof, because it is a method using a rewrite program written in the rewrite ROM, so it is simple and practical and easy to use. In addition, even if the number of optional operation programs that perform control different from the standard operation program described above increases, it can be easily handled as compared with the conventional method using a combination of operation buttons. Also, in this change method, the memory ROM storing the operation program is removed, and a rewrite ROM is attached instead. Therefore, the operation program is executed during rewriting. Absent. Further, in this changing method, the operation program cannot be changed on the user side unless the rewrite ROM is passed to the user side.
[0006]
Further, in the method for changing the operation program of the garbage truck according to claim 2 of the present invention, the rewriting of the command value by the above-mentioned rewriting ROM is performed by the rewriting program stored in the rewriting ROM being loaded or discharged. It is performed by being executed based on the button operation of the predetermined operation button set for changing the operation program, and the predetermined operation button is provided on the operation panel of the garbage collection vehicle. For example, a load button, a discharge button, and the like. By a control signal from these button operations, for example, the controller executes a rewrite program, and a read command value of a standard operation program corresponding to the button operation is read as an optional operation. It is designed to be rewritten to the program read command value.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment according to a method for changing an operation program of a garbage truck according to the present invention will be described with reference to FIGS.
This change method is applied to the operation program of the garbage truck 1 having the rotary plate type loading device 13 as shown in FIG.
First, the configuration of the garbage truck 1 will be described with reference to FIGS.
This garbage collection vehicle 1 is roughly configured by a cab 2 in front of the vehicle and a dust storage box 3 and a dust input box 4 disposed behind the cab 2. Of these, the cab 2 is provided with a driver's seat (not shown) as well as a controller 5 as a central control device having a built-in memory 5a. While sending and receiving signals to and from the memory ROM 6 in which various operation programs to be described in detail are stored, the main switch 7, the PTO switch 8 and the loading / discharging changeover switch 9a arranged on the control panel 9, While signals from the changeover switch 9b and the container box up / down changeover switch 9c are input, control signals to the discharge device 10 and the loading device 13 described later are output.
[0008]
On the other hand, the refuse storage box 3 is inclined so that the part located in the front of the vehicle is pushed up with the part located in the rear of the vehicle as a fulcrum. A discharge device 10 for discharging the loaded dust is provided. In addition, the dust input box 4 whose upper front portion is supported at the rear part of the dust container 3 is swingable with respect to the dust container 3 by the expansion and contraction of the lift cylinder 11 installed between the dust container 3 and the dust container box 3. The rear opening of the dust container 3 is opened and closed by such swinging, while the dust container 4 is locked to the dust container 3 by the lashing device 12 having the lock cylinder 12a. It has become so. In addition, a loading device 13 for loading the dust charged in the dust charging box 4 into the dust containing box 3 is provided in the dust charging box 4, and the loading plate 13 has a pressing plate 13a. 14 is swung in the direction indicated by the arrow (FIG. 1), and the rotating plate 13b is rotated in the direction indicated by the arrow (FIG. 1) by a hydraulic motor (not shown).
An operation panel 15 is provided at the lower rear surface of the dust box 4. The operation panel 15 includes a loading button 15a, a reverse button 15b, a push button 15c, a return button 15d, which are operated by an operator. A stop button 15e and the like are arranged, and signals from these switches 15a to 15e and the like are respectively input to the controller 5 (see FIG. 2).
[0009]
An example of the operation performed in the garbage collection vehicle 1 having such a configuration will be described in the ascending operation for raising the dust input box 4 in order to discharge the dust loaded in the dust container 3. The standard operation of the ascending operation is composed of operations A to D (hereinafter referred to as standard operations A to D), and these standard operations A to D correspond to the standard operations A to D stored in the memory ROM 6. Operation programs A to D (hereinafter referred to as standard operation programs A to D) are read out by the controller 5. That is, these standard operations A to D are performed by the controller 5 using the standard operation program A stored in the memory ROM 6 through the read command values of the standard operation programs A to D written in the memory address of the built-in memory 5a. This is done by calling and executing ~ D in order. Note that the built-in memory 5a is a storage-holding memory in which the storage is held even when the power is turned off.
[0010]
This will be briefly described with reference to the schematic diagram shown in FIG. Note that option operations A ′ to D ′ corresponding to the standard operations A to D can be selected (for convenience of explanation, there is one option operation), and therefore, an option operation program corresponding to the option operations A ′ to D ′. Assume that A ′ to D ′ are set. Then, each read command value of the standard operation programs A to D is set to logic “0” (hereinafter simply referred to as “0”), and each read command value of the option operation programs A ′ to D ′ is set to logic “1” (hereinafter referred to as “0”). Simply referred to as “1”).
As shown in FIG. 3, “0” is written in the addresses K to N of the built-in memory 5a of the controller 5 so that the standard operation programs A to D are called (however, K to K of the built-in memory 5a). It is assumed that information for operations A to D is written in address N). On the other hand, the memory K6 in the memory ROM 6 (the same symbols as those in the built-in memory 5a are used for easy understanding) corresponding to the command value “0” and the standard operation programs A to D. However, option operation programs A ′ to D ′ are written corresponding to the command value “1” (information for operations A to D are written at addresses K to N of the memory ROM 6, respectively). It goes without saying that this is the case).
In such a state, the controller 5 determines that each command value at the addresses K to N of the built-in memory 5a is “0”, and is stored in the addresses K to N of the memory ROM 6. Standard operation programs A to D corresponding to the command value “0” are sequentially called and executed. Thus, standard operations A to D are performed in the garbage truck 1.
[0011]
Specifically, the standard operation A is a loading / discharging operation performed when the main switch 7 is turned on and the engine is started and the PTO switch 8 is turned on, and the standard operation B is When the input box up / down changeover switch 9b of the control panel 9 is on the ascending side, the dust input box 4 is raised, and the standard operation C is a rotating plate 13b for raising the dust input box 4. Is reversed by a predetermined time or a predetermined angle, and in that state, the pushing plate 13a is swung back and returned, and the standard operation D is a dust throwing box 4 by the lashing device 12 by operating the lock cylinder 12a. In this state, the lift cylinder 11 is operated to lift the dust container 3.
[0012]
Next, a method for changing the operation program will be described with reference to FIG. In FIG. 4, the same components as those in FIG. 3 are denoted by the same reference numerals.
Here, a case will be described in which the option operation C ′ is selected instead of the standard operation C, and therefore the option operation program C ′ is executed instead of the standard operation program C.
When changing, the memory ROM 6 is removed after turning off the main switch 7 and the rewriting ROM 16 is attached instead, and then the rewriting program of the rewriting ROM 16 is executed by turning the main switch 7 back on. Create an environment.
In the present embodiment, the return button 15d of the operation panel 15 is operated, and the rewriting program is executed by the controller 5 based on the control signal from the button operation, and the memory M address of the built-in memory 5a is shown in FIG. As shown, the read command value “1” is written. That is, the read command value “0” of the standard operation program C of the operation C corresponding to the button operation is rewritten to the read command value “1” of the option operation program C ′ of the option operation C ′. Thereby, the change of this operation program is completed. After completion, the engine is stopped, the power is turned off, the rewriting ROM 16 is removed, and the memory ROM 6 is attached.
[0013]
Thereafter, the option operation program C ′ is executed instead of the standard operation program C, and therefore the option operation C ′ is performed instead of the standard operation C. That is, the controller 5 sequentially determines the command values at the addresses K to N of the built-in memory 5a, and determines that the command value is “0” at the addresses K and L. The standard operation programs A and B corresponding to the command value “0” stored in the memories K and L of the memory ROM 6 are sequentially called and executed. However, since the controller 5 determines that the command value is “1” at the memory M address, the controller 5 calls the option operation program C ′ corresponding to the command value “1” stored in the memory M address of the memory ROM 6. Execute. Then, since it is determined that the command value is “0” at the next memory address N, the standard operation program D corresponding to the command value “0” stored in the memory address N of the memory ROM 6 is called as described above. And execute. Thus, the standard operation A, the standard operation B, the option operation C ′, and the standard operation D are performed in the garbage collection vehicle 1 in this order.
Here, the optional operation C ′ is an operation in which the operation of swinging the pushing plate 13a backward and returning it is not performed among the operations of the standard operation C.
[0014]
As described above, in the present embodiment, the method of changing the program so that the optional operation C ′ is performed instead of the standard operation C has been described. For example, instead of the standard operation C, the optional operations C ₁ , C ₂ , C ₃ When either one can be selected, for example, the read command value of the standard operation program C is set to logic “00”, and each read command value of the option operation programs C ₁ , C ₂ , C ₃ is set to logic “01”. ”,“ 10 ”,“ 11 ”, and the optional operations C ₁ , C ₂ , C ₃ may be performed instead of the standard operation C. Also, the program can be changed so that a completely different standard operation E is performed instead of the standard operation C, or the program is changed so that a new standard operation F is added between the standard operation C and the standard operation D. In addition, if this change method is used, since this change method is a method using a rewrite program written in the rewrite ROM, it can be easily handled as compared with a conventional method using a combination of operation buttons.
[0015]
【The invention's effect】
According to the method for changing the operation program of the garbage truck according to the present invention, unlike the conventional method using the combination of the operation buttons and the operation method, the method is based on the rewrite program written in the rewrite ROM. In addition to being simple and practical and easy to use, even if the number of optional operation programs corresponding to the standard operation program described above increases, it can be easily handled as compared with the conventional method using a combination of operation buttons.
