Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an improvement in a control device for a mobile bridge construction device.

[Conventional technology]

FIG. 3 shows a control device for a conventional mobile bridge construction device (hereinafter referred to as construction device). Bridge body 1 as shown in the figure
1,12% Vehicle 13. A position sensor 20 and a solenoid valve 21 are installed in the erection device 10 having the main jib 14. The signal from the position sensor 20 is sent to the position sensor input circuit 31. of the control device 30. Arithmetic circuit 33, display drive circuit 3
4 on the display 41 in the operation panel 40. The operator of the erection device 10 uses the display 4 and the erection device 1.
0 status and commands the next operation from the operation panel 400 switch 42. The command signal is transmitted to the solenoid valve 21 through a switch input circuit 36, an arithmetic circuit 33, and a solenoid valve drive circuit 32 of the controller 30, and operates the construction device 10. The operator repeats the above operations depending on the erection or removal operation.

[Problem that the invention seeks to solve]

In the conventional control device for the construction equipment described above, the stain magnetic valve 21 is driven by the switch 42 on the operation panel 40 in response to the erection or removal operation, and the next operation ( switch selection).

The operation of the erection equipment flxo is as follows: Slide the divided bridge bodies 11 and 12 forward and remove the bridge body 11.
be integrated with. Slide the integrated bridge body forward again and lower the tip of the bridge body. Lower the rear end of the bridge body. Vehicle 13
and remove the main jib 14 from the bridge body.

In addition, in the case of withdrawal, the above operation can be performed in reverse.

As described above, the operation of the erection device 10 is extremely complicated.

If an operator considers and executes this complicated operation for each operation, it will take a long time to erect or take down the structure, and there is also a large possibility of erroneous operation.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a control device for a mobile bridge construction device that allows the operator to easily understand the operation to be performed next, reduces the number of decisions required by the operator, and thereby reduces the burden on the operator. With the goal.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention includes a storage means for storing operation details to be performed for each operation of a mobile bridge construction device;
Display content specifying means for specifying display content, selection means for selecting operation content stored in the storage means according to the specification of the display content specification means, and operation content selected by the selection means and actual execution. The selection means selects from the storage means a comparison means that produces an output when the two match, and an operation content to be executed next when an output is generated from the comparison means, from the storage means. It is composed of a display means for displaying.

[For production]

With this configuration, it is possible to notify the operator that the current operation has been completed, thereby reducing the burden on the operator.

〔Example〕

Hereinafter, the present invention will be explained with reference to FIGS. 1 and 2. Here, only the points that are different from FIG. 3 will be explained, and the other parts will be given the same reference numerals and the explanation thereof will be omitted. The operation panel 40 is provided with a display designation switch 50 for designating the content of the urgent operation to be performed. Switch input circuit #0 inputs the signal from this display designation switch 5o to the control device 30.
The display contents are input to the display contents calculation circuit 61 via the display contents calculation circuit 61 so that the display contents can be designated. Further, the control device 3o is provided with a display content storage circuit 63, in which the content to be displayed is stored in advance.The control device 30 is also provided with a display content selection circuit 62, in which the content to be displayed is stored in advance. The display contents stored in the display contents storage circuit 63 are selected based on the display contents stored in the display contents storage circuit 63. Further, the output of the display content selection circuit 62 is outputted to the display device 'IOK' via the display content output circuit 64. moreover,
A comparison circuit 8 compares the operation to be performed currently selected by the display content selection circuit 62 with the operation content of the erection device 1o actually executed by the position sensor circuit 31.
o, the two are compared, and if they match, a signal is sent to the display content calculation circuit 61.

FIG. 2 is a block diagram showing in detail the display content calculation circuit 61 and display content storage circuit 63 of FIG. 1. Erection signal gl & and withdrawal signal 61b
The content of is determined. The previous screen signal 1'fJC and the next screen signal 6zd enter the counter 61f. Here, the counter gzf is an up/down counter, and the previous screen signal 6
1c, the content is down, and the next screen signal 61d is up. The contents of the flip 70 knob 61e and the contents of the register sxf are added by an adder 1t1g, and the contents of the display are determined. The display content storage circuit 63 stores display content (I) r
; The display content (N) is divided from s a into display content (N) 63 n and selected by the display content selection circuit 62 . The selected display content is compared with the status of the erection device 10 detected by the 1-position sensor input circuit 3 in the comparison circuit 8o, and if they match, it is inputted to the counter 61f through the OR circuit 81.

As described above, according to one embodiment of the present invention, the content of the urgent operation currently being performed selected by the display content selection circuit 62 in the comparison circuit 80 is compared with the content of operation of the erection device 10 by the position sensor input circuit 31. If the two match, the next operation to be performed is displayed in the display content selection circuit 621.
Since the information is displayed in letters and stamps on the display 70 via the display content output circuit 64, it is possible to inform the operator of the work status, reduce the operator's judgment, and reduce the burden on the operator. .

〔Effect of the invention〕

According to the present invention described above, there is provided a storage means in which the contents of operations to be performed for each operation of the mobile bridge construction device are stored, and a display contents specifying means for specifying one display contents.

A selection means for selecting the operation contents stored in the storage means according to the specification of the display contents specification means, and a comparison between the operation contents selected by the selection means and the operation contents actually executed, and 1 when the two match. The present invention is constructed of a comparison means that generates an output when an output is generated from the comparison means, and a display means that the selection means selects from the storage means and displays the operation content to be performed when the output is generated from the comparison means. This allows the operator to be aware of the work status and reduces the operator's judgment.

This makes it possible to provide a control device for a mobile bridge construction device that can reduce the burden on the operator.
