Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction management system for performing unmanned construction management using a GPS (positioning system using an artificial satellite) in civil engineering work such as construction work, and more particularly to a remote control system. The present invention relates to the development of a GPS unmanned construction management system that realizes unmanned construction in which the operability equivalent to that of a manned construction machine is exhibited in a type using a construction machine.

[0002]

2. Description of the Related Art In recent years, debris flow countermeasure works in active volcanoes,
In special works such as industrial waste treatment countermeasures, it is necessary to carry out construction work with unmanned construction machinery from the viewpoint of ensuring health and safety. In the above, a positioning system using at least five GPS satellites, a fixed station that receives radio waves from the GPS satellites, and a construction machine that functions as a mobile station that transmits and receives data to and from the fixed station. There has been proposed a configuration in which a construction robot is used to perform unmanned construction using a GPS positioning system capable of measuring the position of a construction machine (Japanese Patent Laid-Open No. 4-2966).
No. 83).

[0003] However, the GPS positioning system is only one of the elemental technologies of an unmanned construction robot that simply runs an unmanned construction machine and runs the robot. However, it is extremely difficult to operate a construction machine so as to perform the essential functions of the machine such as excavation, embankment, and embankment, so that it is not possible to meet the demand for unmanned construction at this stage.

[0004] In addition, as for a technical means for realizing unmanned construction by remotely operating a construction machine, conventionally, a volumetric survey image and a plan image of a mountain being constructed are superimposed and monitored. It is disclosed that the construction machine can be remotely controlled by displaying it on a display device provided at the center so that the current formation of the ground can be grasped by comparing it with a plan drawing (Japanese Patent Laid-Open No. Hei 10-260,837). 4-290915).

However, in this type, a volume measurement image in each direction obtained by processing an image taken by each video camera previously arranged at each location in the site, and a corresponding plan in each direction. It is a configuration that superimposes the image and displays it on the display device, because the image in the direction in which the video camera is set in advance, that is, only the volume for the plan drawing in the direction can be grasped,
Even if the progress of the construction work can be grasped, it is practically impossible to finish the ground according to the planned position and the planned height while looking at the display device. Even so, considerable skill of the operator is required to operate the construction machine so that it can perform its essential functions without being able to obtain information such as the field of view and sense of balance when in the driver's seat. The fact is that empirical facts show that it is difficult to apply to on-site construction work, so it cannot meet the demand for unmanned construction.

[0006] Furthermore, when an earthwork such as a construction work is performed by manned construction equipment by man, it is necessary for the operator to carry out the work while sitting in a driver's seat. doing.

In other words, while the operator is still in the driver's seat, a surveying technician surveys the site in advance using a lightwave range finder or the like, and confirms the planned position and planned height indicated on the installed tent. Since it is not possible to do so, ask the counterpart worker to look at the tenement and check the exact plan position or plan height, or temporarily stop the construction machine if there is no counterpart worker It is necessary for the operator himself to get off the construction machine, adjust his eyes to the height of the stake and see several stakes, or adjust the scale by putting a water thread on the stake Therefore, besides the operator who directly performs the work such as excavation and excavation, a phase number worker who checks the stake is required and labor costs will increase, or complicated confirmation work by the operator himself Need construction machinery Also it will be Basel.

[0008]

SUMMARY OF THE INVENTION Therefore, the present invention
While unmanned construction machinery was used, the irrationality that actual construction could not be practically avoided was avoided. It is an object of the present invention to provide a GPS unmanned construction management system that can be completed, and thus eliminates play time of a construction worker or a construction machine required when operating a manned construction machine.

[0009]

That is, a GPS unmanned construction management system according to the present invention has a structure as shown in FIG.
Position detecting means 2 for detecting the position of the remotely controlled construction machine 3 in real time using at least five GPS satellites 1 and remote control functioning as a mobile station Y provided in an unmanned area A of the construction area Construction machine 3 and a television camera 4 for photographing the movement of the remote control construction machine 3, and a monitor screen 5 provided in a manned area B other than the unmanned area A
a, GPS unmanned construction management having a remote control room 5 having a computer 5b and a remote control panel 5c and functioning as a fixed station X, and a remote control vehicle 6 moving between an unmanned area A and a manned area B A construction information display means 7 for displaying the position of the remote control type construction machine 3 and the construction status grasped from the position on the monitor screen 5a together with the construction plan by the computer 5b; Is displayed on the monitor screen 5a in real time.

In such technical means, any one of the 24 GPS satellites arranged around the earth is appropriately selected as the GPS satellite 1 from the viewpoint of enabling positioning from anywhere on the earth. G
The difference between the time when the radio wave transmitted by the high-precision atomic clock incorporated in all the PS satellites transmitted the GPS satellite and the time when the radio wave was received at the measurement point, that is, the arrival time of the radio wave, was measured from the GPS satellite. The distance to a point can be determined.

The reason why the minimum number of the GPS satellites 1 is set to 5 is that since the radio waves are greatly affected by the ionospheric interference and the like, an error of several tens of meters would be included in the measurement using a normal method. Therefore, the original three unknowns, that is, the error (correction value) must be included separately from the values x, y, and z of each coordinate of the observation point, and the actual unknowns are four in total. Therefore, it is necessary to obtain and analyze data from 4 GPS satellites, and from the viewpoint of adding an automatic initialization function (on the fly), 5 GPS satellites or more are required.

Further, the position means detecting means 2 may be any means capable of measuring the position of the remotely operated construction machine 3 in real time within a range that does not hinder the accuracy of the finishing work such as earthwork. At least 5 GPS
Two points on the ground to receive radio waves from satellites,
A GPS positioning system including a GPS antenna and a receiver installed at the fixed station X and the mobile station Y, respectively, and data relating to radio waves transmitted from GPS satellites between the fixed station X and the mobile station Y. And a wireless communication system that performs transmission and reception.

In this case, the remotely operated transport vehicle 6
Differs from the remote-controlled construction machine 3 in that it works across unmanned areas A and B, and serves to carry out the excavated earth and sand from the unmanned areas A to the manned areas B. Conversely, it plays a role of transporting materials such as ready-mixed concrete from the manned area B to the unmanned area B, and will be changed according to the use according to the construction content in the unmanned area A.

The television camera 4 only needs to be able to capture the operation of the remote-operated construction machine 3, but from the viewpoint of obtaining images from multiple directions and improving the operability of the operator, one TV camera 4 is required. Preferably, two or more television cameras 4 are installed for each remote-controlled construction machine 3.

In this case, from the viewpoint of not only obtaining images from multiple directions but also obtaining images from directions that are easier for the operator to operate, the work of the remote-operated aerial work vehicle is performed at a high place. It is preferable that the aerial work vehicle is mounted on a stand. If necessary, the aerial work vehicle can be moved to a desired position by remote control, and the television camera 4 itself can be remotely controlled. To the desired orientation.

Further, the remote control room 5 has a structure capable of surmounting the wind and snow so as not to damage the monitor screen 5a, the computer 5b and the remote control panel 5c. Since it functions as the fixed station X, it is necessary to maintain a stationary state at least during measurement by the GPS positioning system.

The remote control room 5 must be provided in a manned area B other than the unmanned area A because the operator performs remote control.

Further, as the construction information display means 7, the position data of the remotely operated construction machine 3 obtained by the position means detection means 2 and the construction status grasped from the position data together with the construction plan are displayed on the monitor screen 5a in real time.
Is required to be able to be visually displayed on the monitor screen 5a.
Means is displayed on the monitor screen 5a in real time, and the remotely operated construction machine 3 expressed according to the scale of the figure is displayed on the monitor screen 5a in real time.

The television image display means 8 is not limited as long as an image from the television camera 4 can be displayed on the monitor screen 5a in real time. From the viewpoint of ensuring a clear and clear monitor image, a remote-controlled relay van is provided at an appropriate location as a relay means, and the monitor screen 5a in the remote control room 5 is provided via the remote-controlled relay van. Preferably, screen data is transmitted.

An operator 35 for operating the radio control panel 37 is arranged.

The configuration of the communication system according to this embodiment includes three communication routes: (1) wireless transfer of TV camera image information, (2) detection of position data and the like and display on a monitor screen, and (3) radio control. Has become (1)
And (3) are routes using only the wireless communication system, while (2) is a route using both the GPS positioning system and the wireless communication system.

(1) Wireless transfer of TV camera images In the mobile radio control room 22 which is the fixed station X, the operator 35 obtains real-time information required for radio control operation from the monitor screen 33 while controlling the radio control panel 37. Is operated to control the first radio controlled bulldozer 14 as the mobile station Y, the first radio controlled bulldozer 14 operates to perform its original functions such as excavation and pushing soil as instructed by the radio control operation of the operator 35. Will be.

Then, the first radio controlled bulldozer 14
Is photographed from each direction by a television camera T disposed at each place in the site, and this image data is transferred to a television monitor 33a disposed in front of the operator 35 via the wireless relay device 19a. Is displayed.

(2) Detection of Position Data and Display on Monitor Screen In the first radio controlled bulldozer 14, distance data between the electric center point of the GPS antenna 14a and the GPS satellite 26 is measured in real time by the GPS receiver 14b. New measurement data N1 measured following the movement of the electrical center point is sequentially input to the computer 14f.

On the other hand, in the mobile radio control operation room 22, the electric center point of the GPS antenna 22a and the GPS

(3) Radio control As described in (1), the operator 35 looks at the image information including the first radio-controlled bulldozer 14 displayed on the television monitor 33a in real time, and can communicate with other construction machines. Of the first radio controlled bulldozer 14 displayed in real time on the computer-dedicated monitor 33b as described in (2). By looking at the plan view or cross-sectional view including the diagram, it is possible to grasp the construction status and the position of the first radio-controlled bulldozer 14 with a precision of 1 to 2 cm with respect to the construction plan which could only be confirmed by the conventional method in the past. The first radio-controlled bulldozer 14 can be securely operated through a simple operation of the radio-controlled operation panel 37.
Can be radio controlled.

Next, a construction management process performed by controlling the radio-controlled construction machine according to this embodiment will be described with reference to the overall configuration diagram of the GPS unmanned construction management system shown in FIG. Here, as the radio-controlled construction machine, for example, the first radio-controlled bulldozer 14 will be described.

First, image information captured by the television camera T is transferred in real time to the wireless relay device 19a mounted on the radio crawler dump 19, and then transferred from the wireless relay device 19a to the television monitor 33a for display. .

As a method of transferring image information in this embodiment, a method of relaying by the wireless relay device 19a is employed, so that it plays a particularly effective role against a communication failure in a mountain area or the like. Since the wireless relay device 19a is mounted on the radio-controlled crawler dump, it is possible to flexibly respond to a change in the communication state.

In this way, each piece of information is displayed on a separate monitor on the monitor screen 33. In the present embodiment, however, a plurality of screens are installed in one place instead of being separated. Moreover, since the operator 35 operates the radio control operation panel 37 so as to face the monitor screen 33, all of this information can easily enter the field of view of the operator 35.

For this reason, it is possible to effectively appeal to the visual sense of the operator 35, and there is a situation in which information such as a field of view and a sense of equilibrium, which should be obtained when the driver gets into the driver's seat, cannot be obtained. As a result, the radio control operation panel can be operated as easily and reliably as possible, and as a result, the functions of the first radio controlled bulldozer 14, such as excavation and earth pressing, are sufficiently exhibited.

In addition, visual information based on the position data of the first radio-controlled bulldozer 14 with extremely high accuracy of 1 to 2 cm, that is, the construction status with respect to the construction plan and the positional relationship of the first radio-controlled bulldozer 14 are updated in real time. Computer dedicated monitor 33
b), so that not only the work of surveying and setting up the stakes, which had been performed in the previous construction, can be eliminated, but also the work of confirming the planned position and planned height indicated on the stakes Since the operation can be performed without stopping the operation of the radio control panel, unmanned construction can be continuously performed until the final finishing work.

When the first radio controlled bulldozer 14 is radio-controlled in this manner, image information that fluctuates following this operation is displayed on the television monitor 33a by the television camera T via the radio relay device 19a. The construction information based on the position data of the first radio-controlled bulldozer 14 grasped by the GPS positioning system and the wireless communication system is also displayed on the computer-dedicated monitor 33b via the computer. On the basis of the above, each radio-controlled construction machine is controlled, and the construction is properly and safely managed throughout the site.

Further, according to this embodiment, the position of the radio-controlled construction machine is grasped through the computer, so that, for example, at the end of a day's work, various radio-controlled construction machines can be moved to the unmanned area A. By running over the entire area and accurately measuring the ground shape on the day, and calculating the difference from the ground shape on the previous day, it is possible to easily know the construction work on the day, The construction machine can be specified to easily grasp the construction frequency, construction capacity, and the like of the construction machine, and these results can be recorded and used when necessary.

Further, not only is it possible to operate the construction machine while simply grasping its own position data and the like, but at the same time, real-time physical work and construction frequency in a specific area can be obtained from the construction machine position data. The grasped result can be easily recorded in a record, and high-quality construction management can be performed without any person.

Further, since the present invention realizes unmanned construction, when operating manned construction machinery, a check number for confirming the required plan position and plan height indicated on the tonnage, which was required. Not only is the operator unnecessary, but also the operator himself does not need to perform the work of checking the tension, which can eliminate complicated work, and also eliminates the play time of the construction machine associated with the work of checking the tension of the operator. You can also.

Furthermore, not only can the construction machine be operated while simply grasping its own position data, etc., but at the same time, the physical work and the construction frequency in a specific area can be determined in real time from the construction machine position data.
