The personal computer 33 searches the master data on the database 35 (step S13), and compares the optimum value and the actual value by pattern matching (step S15). Subsequently, in step S17, a trouble determination is made based on whether each information from the construction site 10 is within the range of the optimum value.

Here, when it is determined that there is no trouble within the range of the optimum value, the construction site 10 is notified via the public line 20 that there is no problem.
This information is displayed as needed on the display screen of the excavation propelling machine operating device 11 or the personal computer 13 of the construction site 10.

On the other hand, if it is determined in step S17 that there is a trouble state, the process proceeds to step S19, where a countermeasure method is determined, and the countermeasure method obtained from the support information of the master data on the database 35 is applied to the construction site 10.

Here, the countermeasures presented to the construction site 10 are the same as in the case of “no problem”, as in the excavation propulsion machine operating device 11 or the personal computer 1 of the construction site 10.
Only the display screen of No. 3 may be appropriately displayed as needed, but the remote control of the excavation propulsion machine of the construction site 10 may be used.

Next, a specific example will be described with reference to FIGS.

Here, the outline of the information shown in FIGS. 4 and 5 will be described.

First, the soil classification, which is the soil information, indicates the type of the soil such as gravel and clay. The N value is a parameter representing the hardness of the soil and is displayed as a numerical value from 0 to 50. The larger the value, the harder the soil is. The overburden indicates the distance from the ground to the propulsion unit, and the groundwater level indicates the distance from the ground to the groundwater. In addition,
This soil information is obtained in advance by a geological survey such as underground boring, transmitted to the support center 30, and stored in a database.

The mud pressure, which is the propulsion information, indicates the pressure between the excavator and the soil, and the mud here refers to a mixture of excavated soil and a mud agent. , The propulsion speed indicates the underground propulsion speed of the excavator, and the original pressing force indicates the force applied to the main pushing device when the excavator is pushed, and the amount of the mud-producing agent and Is the injection amount of the mud making agent injected into the soil from the tip of the excavator.
The mud excavated by the mud is imparted with fluidity to form mud and is carried out to the surface of the earth, and the mud is reduced in friction when the excavation propulsion machine advances in the soil.
Further, with respect to the mud-producing agent, see, for example,
No. 67, entitled "Method of producing aqueous mud-forming agent".

Similarly, the mud-forming agent injection pressure, which is the propulsion information, indicates the pressure at which the mud-forming agent is injected, and the cutter hydraulic pressure indicates the pressure applied to the cutter head at the tip of the excavator. It is. The promotion information is sequentially set at the time of construction, or is obtained by construction according to the setting.

The earth removal amount, which is the earth removal information detected by the earth removal information detecting unit, is a flow rate indicating the earth removal discharged by the propulsion unit every unit time. It indicates the type of soil removal (gravel, clay, etc.), viscosity, and the mixing state of the mud-producing agent into the soil removal. Further, the mud-forming agent information, which is the mud-forming agent type, indicates the type of mud-forming agent injected into the soil from the tip of the excavator, and the viscosity indicates the viscosity ratio of the mud-forming agent used. .

Next, with reference to FIG. 4, a description will be given of a support procedure in the trouble determination regarding the mud pressure of the remote support system.

In FIG. 4, soil information (soil classification, N value, earth covering,
It is assumed that groundwater level, etc.) and machine information (machine model number, pipe type, pipe diameter, etc.) are transmitted to the support center 30 and stored in the respective databases.

In step S21, the support center 30
The personal computer 33 performs pattern matching, and calculates an optimum mud pressure value from the database from the discharge information and the soil information. Trouble determination is performed by comparing the calculated mud pressure value with the actual mud pressure value (step S23). Here, when it is determined that the value is within the range of the optimum value, the fact that there is no problem is notified to the construction site 10 via the public line 20 and the process is terminated.
Further, when it is determined that there is a trouble outside the range of the optimum value, the trouble factor is determined from the database (step S25). Here, even in the same trouble state, the cause of the trouble is different depending on, for example, the amount of discharged earth and the nature of the discharged earth. When the cause of the trouble is determined (step S27), a countermeasure method corresponding to the cause of the trouble, for example, a propulsion speed of the excavation propulsion machine according to the pipe diameter, an injection amount of the mud-producing agent, and the like, are calculated. The determination is made by comparison with the optimal injection rate based on the parameters (step S29), based on which the optimal operation method is presented (step S31), and the support is terminated.

For example, as for the mud pressure, when it is reported from the construction site 10 that “the upper limit of the mud pressure is exceeded and no or little discharge is generated”, “the mud passage is closed or the discharge is blocked. Is determined to be a trouble.
An advice such as “decrease the propulsion speed and check whether the mud pressure is reduced” is provided to the construction site 10.

Next, with reference to FIG. 5, a description will be given of a support procedure in the trouble determination regarding the main pushing thrust, the injection pressure, and the cutter pressure of the remote support system.

In step S41, pattern matching between the original pushing thrust of the propulsion information of the construction site 10 and the optimum original pushing thrust value of the support center 30 is performed. In step S43, pattern matching is performed between the mud-forming agent injection pressure and the optimum injection pressure value of the propulsion information. In step S45, pattern matching is performed between the cutter oil pressure of the same propulsion information and the optimum cutter oil pressure value.

A trouble determination is made from these pattern matchings (step S47). Here, when it is determined that the value is within the range of the optimum value, the fact that there is no problem is notified to the construction site 10 via the public line 20 and the process is terminated. Further, when it is determined that there is a trouble outside the range of the optimum value, the cause of the trouble is determined from the database (step S49). When the cause of the trouble is determined, a countermeasure method corresponding to the cause of the trouble is determined, and an optimal operation method is presented based on the determined method (step S51), and the support ends.

As described above, according to this embodiment, since the construction site and the support center are connected by the public line, it is possible to collectively support the excavation propulsion machine at a plurality of construction sites from a remote place. This makes it possible to provide more support than the skilled operator. Further, since a single support center can support a plurality of construction sites, the cost of the system can be reduced.

Such optimal operation of the excavator from a remote place is realized by the remote support program for the excavator according to the present invention, and the remote support program is provided by being recorded on a recording medium.

[0047]

As described above, according to the present invention, since the construction site and the support center are connected by a public line, it is possible to remotely support the excavation propulsion machine at the construction site. Even if there are a plurality of construction sites, it is possible to provide support almost at the same time as that of a skilled operator.
