Abstract

A system for controlling and/or monitoring and/or visualizing construction sites, including a detection device for detecting the position of a construction unit at the construction site, wherein the detection device includes a signal transmitter to be mounted on the construction unit for providing an identification signal identifying the construction unit, and a signal evaluation device for receiving and evaluating the identification signal in order to determine the position of the construction unit at the construction site. The signal evaluation device includes at least one loop antenna that is laid at the construction site for receiving the identification signal of the signal transmitter and for determining the position of the signal transmitter.

First claim

The invention claimed is:

1. A logistics system for construction units comprising:
one or more signal transmitters, each configured to be mounted on a construction unit and to provide identifying information related to the construction unit to which it is mounted, the identifying information comprising an electromagnetic signal; and
a signal evaluation device comprising one or more loop antennas, each loop antenna configured to:
receive the identifying information from a first signal transmitter of the one or more signal transmitters by detecting a magnetic component of the electromagnetic signal when the first signal transmitter is in proximity to the loop antenna; and
evaluate the received identifying information;

wherein the one or more loop antennas are positioned about a construction site; and
wherein the system detects the presence and position of construction units at the construction site.

2. The logistics system of claim 1 , wherein:
the system is configured to monitor positions of at least a portion of the construction units about the construction site via the evaluated received identifying information from at least a portion of the loop antennas; and
at least a portion of the construction units are selected from the group consisting of construction machines, construction materials, building materials, and construction tools.

3. The logistics system of claim 2 , wherein one or more of:
at least a portion of the one or more signal transmitters are configured as transceivers;
at least a portion of the one or more signal transmitters comprise an energy accumulator for actively generating signals representative of the identifying information;
at least a portion of the one or more signal transmitters comprise a microprocessor with an associated memory module;
at least a portion of the one or more signal transmitters comprise at least one sensor from the group consisting of a temperature sensor, humidity sensor, acceleration sensor, brightness sensor, and pressure sensor; and
the signal evaluation device is configured to determine the position of a respective signal transmitter of the one or more signal transmitters relative to a respective loop antenna of the one or more loop antennas with reference to a signal strength induced in different loop antenna portions of the respective loop antenna.

4. The logistics system of claim 2 , wherein the one or more signal transmitters are further configured to directly communicate with each other in the manner of a peer-to-peer system.

5. The logistics system of claim 2 , further comprising a central information unit in information communication with the signal evaluation device;
wherein the central information unit is configured to store identification and position data of at least a portion of the construction units detected at the construction site.

6. The logistics system of claim 5 , wherein the central information unit comprises:
a visualization configurator module for configuring visualization data; and
a transmitter module for transmitting the visualization data;
wherein the visualization data is:
related to the stored identification and position data; and
presented on a display device in communication with the transmitter module.

7. The logistics system of claim 5 , wherein the central information unit comprises a monitoring module configured to:
monitor building progress of a building at the construction site;
match planning data from a building information model (BIM) with the stored identification and position data; and
determine from such matching whether a building step contained in the planning data of the BIM has been executed.

8. The logistics system of claim 6 , wherein the visualization configurator module is further configured to generate image data in dependence on signals representative of the identifying information detected by at least a portion of the one or more loop antennas and position data of at least a portion of the construction units determined therefrom;
wherein the image data defines a respectively updated image of the construction site.

9. The logistics system of claim 1 , wherein each signal transmitter of the one or more signal transmitters is further configured to provide the identifying information in a wavelength range between 50 kHz and 500 kHz.

10. The logistics system of claim 1 , wherein each loop antenna of the one or more loop antennas is further configured to respond to the identifying information in a wavelength range of 50 kHz to 500 kHz.

11. The logistics system of claim 1 , wherein each signal transmitter of the one or more signal transmitters is further configured as an inductive near-field communication module with a signal range of less than 100 m.

12. The logistics system of claim 1 , further comprising a server configured to:
receive the evaluated identifying information;
generate dynamic visualization of the construction site comprising presence of the construction units, position of the construction units, installation status of the construction units, or combinations thereof; and
transmit the dynamic visualization of the construction site to a display device, a mobile device, an augmented reality device, or combinations thereof.
