Then, the management server system 102 waits for the input of the set value, and transmits the set value to the drive control device 44 of the work site system 101 when the set value is input. Then, the drive control device 44 outputs the set value received from the management server system 102 to the control device 28 via the serial communication cable 46.

The control unit 28 stores the received set value in a memory and controls each unit so that the set value is input from the drive control unit 44 (set value received from the management server system 102). It has become.

For example, when a set value for the pull-out stroke is input, the control device 28 sets the set value of the pull-out stroke (elevated amount of the lifting body 20 and the chuck 15) when the pile 2 is pulled out. By operating the fourth control valve 26, the upper and lower hydraulic cylinders 21 are driven. Further, for example, when a set value for the press-fitting stroke is input, the control device 28 sets the press-fitting stroke (the descending amount of the elevating body 20 and the chuck 15) to the set value when the pile 2 is press-fitted. By operating the fourth control valve 26, the upper and lower hydraulic cylinders 21 are driven.

For example, when a set value for the press-fitting speed or the pulling-out speed is input, the control device 28
Operates the fourth control valve 26 so that the set value is obtained when the pile 2 is pressed or pulled out, and the vertical hydraulic cylinder 2
1 is driven. Further, the control device 28 outputs a signal to the drive control device 44 via the serial communication cable 46 so that the set values for the press-fitting speed and the withdrawal speed are set, and the drive control device 44 controls the valves 43 and 43 and the engine 4.
By controlling 1, the vertical movement speed of the lifting / lowering body 20 (chuck 15) by the vertical hydraulic cylinder 21 may be set. Further, for example, when a set value for press-in is input, the control device 28 controls the fourth control valve 2 so that the set value of press-in is set when the pile 2 is press-fitted.
6, the upper and lower hydraulic cylinders 21 are driven. When a set value for the number of press-in / pull-out repetitions is input, the control device 28 repeats the operation of the fourth control valve 26 so as to reach the set value of the number of press-in / pull-out repetitions, and drives the up / down hydraulic cylinder 21 up and down. I do.

In the management server system 102, the set value of the clamp force of the clamp 11,
A setting value for the chucking force of No. 5 may be input. These setting values are also stored in the management server system 10.
2 to the drive control device 44, and further output from the drive control device 44 to the control device 28 via the serial communication cable 46. Then, the control device 28 can control the clamp force of the clamp 11 to the set value by operating the first control valve 23, and the fifth control valve 27
Is operated, the chucking force of the chuck 15 can be controlled to a set value.

In the above embodiment, if the system administrator inputs the optimum set values in the management server system 102, the work site system 101 can operate optimally. For example, when the operation state of the work site system 101 is abnormal, if a set value for correcting the abnormality is input in the management server system 102, the work site system 101 operates with the set value. , And can immediately respond to abnormalities. Also,
For example, by repeatedly pressing and pulling out the pile 2,
However, if the number of repetitions of the drawing stroke or the press-fitting / pulling-out increases, the construction efficiency of the pile 2 decreases. In particular, it is difficult for an inexperienced operator to set the drawing stroke and the number of press-pulling / pulling repetitions. However, a skilled worker of the pile press-in / pull-out machine can easily set the pulling stroke and the number of times of press-in / pull-out. For this reason, the skilled worker needs to
Even if the number is smaller than the number, if a skilled person is a system administrator, the number of repetitions of the withdrawal stroke and the press-in / withdrawal of each work site system 101 can be set via the management server system 102. System 101
Can operate efficiently. That is, since it is not necessary to dispatch a service engineer who is an expert to the work site to each work site, it is possible to reduce the cost, time, and personnel involved in operating the work site system.

Further, information on the operating state of the pile press-in / pull-out machine 10, that is, the stroke detector 29 and the press-in detector 3
0, the value detected by the clamping force detecting unit 31 and the chucking force detecting unit 32 and the value of the operating time of the pile press-in / pull-out machine 10 are transmitted to the control unit 28 via the serial communication cable 46.
Is output to the drive control device 44 from the controller. Pile press-in pull-out machine 10
Is also output from the drive control device 44 to the control device 28 via the serial communication cable 46.
On the other hand, a drive signal for controlling the engine 41 and the valve 43 of the drive device 40 is output from the control device 28 to the drive control device 44 via the parallel communication cable 47. That is, the driving signal for driving the driving device 40 is:
Serial communication cable 46 used for information collection
Since the output is performed using the parallel communication cable 47 different from the above, the communication speed of the drive signal does not decrease. Therefore, the drive control device 44 is controlled by the control device 28 more quickly, and the responsiveness related to the drive of the drive device 40 is improved, and the responsiveness related to the operation of the pile press-in / pull-out machine 10 is further improved. When the parallel communication cable 47 is disconnected, the control device 28 outputs a drive signal to the drive control device 44 via the serial communication cable 46.

Since the pile press-in / pull-out machine 10 performs an actual pile press-in operation, it is required to receive a large impact and to be compact. However, in the above embodiment, the management server system 102 and the work site system 1
01 is the communication unit 48 for performing the communication of the drive unit 4.
Since it is provided at 0, the installation location of the communication unit 48 does not need to be considered for the pile press-in / pull-out machine 10, and the pile press-in / pull-out machine 10 becomes compact. Furthermore, since the driving device 40 has less vibration than the pile press-in / pull-out machine 10, stable communication is performed as compared with the case where the communication unit 48 is provided in the pile press-in / pull-out machine 10. The communication unit 48
The communication unit 48 can be installed without considering the anti-vibration measures even when compared with the case where is provided in the pile press-in / pull-out machine 10.

The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention. For example, by adding a drilling device using an earth auger to the pile press-in / pull-out machine 10, while excavating the ground with the earth auger,
A stake may be press-fitted. Further, in the above embodiment, the pile press-in and pull-out machine 10 is used as the work site system 101.
Although the piles are pressed in by using the work, a work site system that suspends a suspended load by a crane, a work site system in which a tunnel is constructed by a shield, or the like can be used as long as the work is performed by a civil engineering machine. In any case, the information relating to the operating state of the civil engineering machine is transmitted to the management server system,
A set value is input in the management server system, and the civil engineering machine operates with the set value.
