Description

[Technical field]

[0001] The invention relates to a method for carrying out construction operations, in particular foundation engineering operations, at a construction site with n construction machines, in particular foundation engineering machines, on which auxiliary parts, in particular construction tools, are fixed in a releasably and exchangeably manner, and N auxiliary parts are stored at the construction site, where N>n>2.

[0002] Furthermore, the present invention provides, as defined in the preamble of claim 8, a method for carrying out construction operations, in particular foundation engineering operations, on a construction site with n construction machines, in particular foundation engineering machines. system On the construction machine, attachments, particularly construction tools, are fixed in a releasably and exchangeably manner, N attachments are stored at the construction site, and N>n>2. system Regarding. [Background technology]

[0003] When carrying out construction procedures, it is often necessary to fasten other construction tools on the construction machine, for example on a drilling rig, during the construction work. For example, when creating a borehole with a drilling rig, in normal ground it may be necessary to use an auger, which allows efficient and rapid drilling progress under normal ground conditions. When the ground layer changes, for example when a rock layer is reached, it may be necessary to change the auger to a rock drill, and when a gravel layer is reached, it may be necessary to use a drilling bucket. In this connection, Individual It is known to equip construction tools with identification devices that can be automatically recognized by the machine. The machine can have detection means, e.g., transmitting and receiving means, and can for example interrogate the identification device on the attached construction tool in a wired or, as is often the case, wireless manner. In this way, the machine operator can reliably know which construction tool is currently fixed. However, this does not work well, since not all construction tools are permanently equipped with such identification devices. Furthermore, especially in the case of wireless-based interrogation, the influence of other construction tools in close proximity can prevent clear identification.

[0004] The control center can retrieve information via individual construction machines regarding which construction tools are currently being used on the construction machines. This information is relevant for scheduling work processes on the construction site and is necessary to identify which construction tools are still available and can be used on other construction machines on the construction site.

[0005] However, knowing the construction tools currently installed on a construction machine is not sufficient for reliable work scheduling: when performing a particular construction operation by operating the construction machine, in principle, other construction tools that are not currently installed on the construction machine but are located in the vicinity of the construction machine and will be required in the near future for retooling may also be involved with the construction machine. That is, in practice, several types of construction tools in a set may be involved with the construction machine.

[0006] As is known, a construction machine operator can determine which set of construction tools is required on the construction machine and therefore is not freely available. Individual The construction site manager is notified even if the construction tool is not installed on the construction machine. However, when this notification is made by the construction machine operator, the construction site manager himself may not receive any notification at all, may receive incomplete or inaccurate notification of the construction tool that is actually required, or may not be notified when the construction action is completed. Individual The availability of construction tools is often inadvertently not reported or reported incorrectly, and as a result, efficient construction site management with work process control as well as efficient provision of the construction tools required at the construction site becomes more difficult. Summary of the Invention [Problem to be solved by the invention]

[0007] The underlying object of the present invention is to provide a method and a method for the efficient implementation of construction procedures on a construction site. system The purpose of this invention is to provide [Means for solving the problem]

[0008] The object is, on the one hand, by a method having the features of claim 1 and, on the other hand, by a method having the features of claim 8. system This is achieved by: Preferred embodiments of the invention are set out in the respective dependent claims.

[0009] The method according to the invention is characterized in that the number n and type of construction machines and the number N and type of auxiliary parts present at the construction site are stored in a computer unit, which Individual It has data connections to construction machines and Individual To inquire about actuators for construction machinery, Individual In response to the received information, the computer unit determines which accessories are fixed on the construction machine and which accessories are available for use at the construction site.

[0010] The basic idea of ​​the invention is to provide a method for enabling a computer unit to reliably identify the construction tool currently installed on the construction machine. Individual The actuators of the construction machine, such as the drive system, rotary drives, linear positioning drives, etc., are interrogated for information about the position of the components of the construction machine, such as the mast, rotary drilling drive, boom, etc. The computer unit is designed to determine on the basis of this information which construction procedure is to be performed by the construction machine, and on the basis of the information stored in the database, the computer unit is able to identify whether and which construction tools are deployed by the construction machine. This information can be used by itself or in conjunction with other information to determine which construction tools are deployed and fixed. In this way, the computer unit: IndividualIt is possible to ascertain, in a largely automated manner, which construction tools are currently deployed by the construction machinery and, through a comparison with a given construction tool inventory, to ascertain which construction tools and how many are actually at hand at the construction site.

[0011] As a result, downtimes caused by lost construction tools on construction machines as well as excess inventory of construction tools can be prevented at construction sites, which leads to considerable cost savings.

[0012] A successful further development of the invention can be found in that Individual The computer unit determines, depending on the received information, which set of attachments is required for the construction machine. Therefore, not only the construction tools currently installed on the construction machine, but also the set of attachments required for the construction procedure are displayed. Each A method is provided which allows the computer unit to identify also the different construction tools which are needed at the time by the construction machine.

[0013] Basically, the machine operator can manually input the attachments currently fixed on the construction machine into the control system, so that the computer unit can interrogate them. According to a further development of the invention, it is preferably provided that each construction machine has detection means, by means of which it is determined which attachments are fixed on the construction machine and / or are in the immediate vicinity. The detection means can be a camera system or a transmitting / receiving means. If desired, it is also possible in this case to detect only the tools that are actually fixed on the construction machine. On the other hand, it is also possible to detect construction tools in the immediate vicinity of the machine, but in that case no reliable and unambiguous assignment can be made as to whether a construction tool is actually needed on the construction machine or whether a construction tool is already fixed on the construction machine. This information, together with further information about the actuators, allows a reliable determination of the required and available construction tools. That is to say, the determination based on information from the actuators of the fixed and deployed construction tools can be checked and verified in the computer unit by means of additional information about the construction tools.

[0014] It is particularly preferred to provide the attachment with a machine-readable identification device. The machine-readable identification device on the attachment can be, for example, an RFID chip that can be interrogated wirelessly. This type of identification device can directly send back a response signal upon receiving a corresponding interrogation signal. This response signal can contain the requisite information about the attachment that has been interrogated. Basically, other identification devices can also be deployed.

[0015] Another preferred embodiment of the invention is that for each construction machine, storage is performed in the computer unit as to which construction action is performed by which set of attachments and which information is required thereby about the actuators of the construction machine. For example, when creating a foundation pile by means of a drilling rig, specific attachments are required simultaneously or alternately, such as Kelly bars, drilling tools, etc., as well as tools for cleaning the bottom of the borehole, etc. In any case, they must be operated with specific rotational speed and feed rate values.

[0016] For example, based on the position along the mast of the rotary drive, a check can be made as to which parts are needed and when, e.g. a tool for cleaning the bottom of a borehole. This can be used by a computer unit, which may be located in a control center, to release the attachments and reserve them for the construction machine. If applicable, the central computer unit can also initiate a procurement process for one or several further attachments to be transported to the construction site. In addition, a notification can be displayed for the construction site manager as to which attachments are no longer needed for further construction actions at the construction site and can be removed from the construction site.

[0017] The location point of another preferred method variant according to the invention is a point where at least one location determination means is provided, by means of which the location of the construction machine and / or the attachments at the construction site is determined and indicated, through which: Individual Construction machinery and Individual A precise location of the attachments can be performed, for example, a suitable construction tool can be assigned to a construction machine when the construction tool is available, and both can be located as close as possible to each other. In this way, the transport process within the construction site can be limited, further increasing the efficiency of the construction action to be performed.

[0018] The position determination means can be realized by a GPS system or a construction site position determination system, in which case the corresponding transmitting and / or receiving means are individual It can be equipped to machines and parts to emit / receive position signals.

[0019] As construction machines, basically all possible construction machines can be envisaged. Those for foundation engineering can be envisaged, inter alia, drilling rigs, grabs, diaphragm wall cutters, excavators, cranes, etc. As regards the accessories, preferably foundation engineering tools are envisaged, more particularly augers, rock drills, drilling buckets or pumps or drilling tools. Basically, other foundation engineering tools and other construction tools can also be envisaged.

[0020] Execution of construction procedures according to the present invention system The feature of the present invention is that a computer unit is provided, in which the number n and types of construction machines at the construction site and the number N and types of auxiliary parts can be stored, and the computer unit Individual It has data connections to construction machines, Individual It is designed to query information about actuators in construction machinery, Individual The computer unit is designed to ascertain, in response to received information, which attachments are fixed on the construction machine, and the computer unit can ascertain and indicate which attachments are freely available at the construction site.

[0021] this system This makes it possible, among other things, to carry out the above-mentioned method, thereby achieving the above-mentioned advantages.

[0022] According to a further development of the invention, it is advantageously possible to determine which set of attachment members is which Individual The computer unit is designed to determine, in response to the received information, whether the construction tool is required by the construction machine, i.e., whether the construction tool is currently installed on the construction machine, as well as the construction tool required to perform the construction action. EachDifferent construction tools that are needed at the time by the construction machine can also be identified, which facilitates and improves work scheduling.

[0023] It is particularly preferred in this context that each construction machine is equipped with detection means, which can detect which attachments are fastened to it and / or are in the vicinity, and which can in particular be transmitting and receiving means for wireless interrogation of the attachments, so that the identity of the fastened construction tools can be verified on the basis of the additional information received.

[0024] According to a further development of the invention, each accessory is preferably provided with a machine-readable identifier, which in particular may be an RFID chip fixed at a suitable position on the accessory.

[0025] By linking several sensor information of different attachments and comparing their motion, e.g. rotation, acceleration or tilt, the machine can conclude which attachments are connected to which other members and ultimately which are connected to the device, based on the sensor information. With this aim in mind, the machine compares the motion information of the sensor systems with the actuator information from the machine.

[0026] For example, after the Kelly bar and drilling tools are installed, the machine rotates its attachments at a certain speed, and by comparing the rotation speeds of all the associated components, the machine detects the components installed on it and eventually blocks them from access by other machines.

[0027] The rotational position or orientation of an attachment, such as a drilling bucket (upright, sideways), can differentiate which tools ultimately become a mounting concern on the machine.

[0028] The basic idea of ​​the invention is not limited to knowing which construction tools are installed. Based on the construction parts / attachments that are installed or connected, a knowledge can be made as to which construction parts are still available. This is important in terms of construction progress, since the tools can be used more efficiently. This allows the tools to be tracked.

[0029] The present invention will now be described in detail with reference to certain preferred embodiments. [Brief description of the drawings]

[0030] [Figure 1] FIG. 1 is a schematic plan view of a construction site with several construction machines and accessories. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] FIG. 1 shows a construction method for carrying out the construction procedure according to the present invention. system 1, a construction site 5 is diagrammatically illustrated together with a construction machine 10. As an example, three construction machines 10 are provided, each of which is equipped with a detection means 12 for detecting an attached member 20. The attached members 20 are specifically construction tools, and are equipped with a recognition device 22. The recognition device 22 can specifically be an RFID chip that can be wirelessly interrogated through the detection means 12 of the construction machine 10.

[0032] The detection means 12 Each It may be part of a control unit of the construction machine 10 , in which case the control unit may also have a wireless data connection to the central computer unit 8 .

[0033] At least one attachment 20 is mounted on each construction machine 10, for example for performing a specific construction procedure or a specific construction step. In addition, other attachments 20 are stored in the open space 6 or in close proximity to the construction machine 10. These currently uninstalled attachments 20 are prepared for rapid replacement on a specific construction machine 10 to perform a construction procedure that envisages a specific work step sequence with various construction tools or attachments 20. The computer unit 8 Individual 10. The construction machine 10 includes a data connection thereto, so that Individual The computer unit 8 queries for information about the actuators of the construction machine 10. In response to the received information, the computer unit 8 determines which attachments 20 are associated with the Individual It is confirmed whether the attachment 20 is fixed on the construction machine 10. The data can be compared and checked with the data of the detection means. This also makes it possible to confirm which attachments 20 are in the immediate vicinity of the construction machine 10 but are not fixed on the construction machine.

[0034] Furthermore, in the tool storage 9, further attachments 20 can be provided which are not in use and are basically freely available.

[0035] In the central computer unit 8, all the attachments 20 present at the construction site 5 are listed together with their number N. Similarly, the number n of construction machines 10 present at the construction site 5 is stored in the central computer unit 8. By querying the detection means 12 and actuator information via the associated control unit of each construction machine 10, the central computer unit 8 can determine which particular attachments 20 are installed on the construction machine 10. If desired, the computer unit 8 can also ascertain which other attachments 20 are in close proximity to each construction machine 10. However, IndividualWhen construction machines 10 are closely spaced relative to one another, such information is fundamentally insufficient and it is difficult to reliably determine which of the attachments 20 in close proximity to a construction machine 10 are assigned to that construction machine, as well as which will be required by that construction machine in the near future and, in some cases, which are already fixed on the construction machine 10.

[0036] Individual The data stored in the computer unit 8 in relation to the construction procedure is stored on the construction machine 10. Individual There is characteristic data about the construction tools or attachments 20 and their order and actuators that are required when the attachments 20 are in use. This allows the central computer unit 8 to check or verify which attachments 20 are in use and which attachments 20 that are not fixed on the construction machine 10 are required in the near future for the construction machine 10 and therefore are reserved for the construction machine and cannot be freely used. That is, through a comparison with a list of all the attachments 20 present, the computer unit 8 can determine which of the attachments 20 present on the construction site are in fact freely available. This can be taken into account by the construction site manager in scheduling the work and can be used in procuring or releasing the attachments 20.

[0037] By means of the machine control 14 on the construction machine 10, information about the actuators of the construction machine 10, i.e. information about the vertical feed movement, the set positions of the setting cylinders and drives, rotational speed information, etc., and other information, can be wirelessly queried via the machine's sensors and transmitted to the central computer unit 8. Within the meaning of the present invention, the term actuator is to be understood as an adjustable and / or movable member of the construction machine 10 which is driven by the attachment 20 to carry out a construction procedure.

[0038] In addition, the central computer unit 8 also detects, via detection means (not shown) in the tool store 9, the number and type of attachments 20 stored there and essentially freely available. The central computer unit 8 advantageously checks the current operation of each construction machine 10 and can determine the need for a particular attachment 20 in a timely manner, possibly in real time. As a result, an attachment 20 in the tool store 9 can be reserved or another attachment 20 at the construction site 5 can be released.

[0039] Furthermore, the construction machines 10 and the attachments 20 can be equipped with location determination means to determine their exact location on the construction site, which can then be displayed as a floor plan on the screen of the central computer unit 8 or, as in the illustrated example, on each construction machine 10.
