Abstract

Industrial vacuum cleaner configured for servicing at least one construction tool, said vacuum cleaner comprising a vacuum inlet, wherein said vacuum cleaner further comprises a controller and connected to said controller a wireless transceiver, a memory, and at least one location and/or orientation sensor configured for detection of vacuum cleaner location and/or localization of other objects in relation to the vacuum cleaner and wherein the vacuum cleaner further comprises means for propulsion controlled by said controller.

Claims (49)

1. A construction system comprising:

an automated vacuum cleaner; and

a construction tool that produces dust or debris due to operation of the construction tool, the construction tool being a mobile construction tool comprising a means for propulsion of the mobile construction tool;

wherein the automated vacuum cleaner is configured to receive a wireless communication of a service request from the construction tool; and

wherein the construction tool comprises:

a controller,

a wireless transmitter connected to the controller, and

a location sensor or an orientation sensor;

wherein the controller is configured to control the wireless transmitter to transmit a location of the construction tool to the automated vacuum cleaner to enable relocation of the automated vacuum cleaner based on the location of the automated vacuum cleaner,

wherein the automated vacuum cleaner is further configure to:

wirelessly connect the automated vacuum cleaner to the construction tool upon reception of the servicing request from the construction tool; and

continuously monitor the construction tool via a wireless connection and responsively move to maintain a following position with the construction tool by changing location or orientation to collect the dust or debris generated by the construction tool.

2. The construction system of claim 1 , wherein the system further comprises a server configured to wirelessly communicate with the automated vacuum cleaner and the construction tool.

3. The construction system of claim 1 , wherein the system further comprises a construction tool control device configured to wirelessly connect to the construction tool and remotely control the construction tool by an operator; and

wherein the automated vacuum cleaner is configured to ensure that the automated vacuum cleaner does not remain, for more than a threshold duration of time, in any location that is located in a line of sight between the construction tool control device and the construction tool.

4. The construction system of claim 1 wherein the automated vacuum cleaner is configured to approach the construction tool in response to the receipt of the service request and move into the following position.

5. The construction system of claim 1 wherein the automated vacuum cleaner is further configured to:

monitor a level of dust collected in a dust container of the automated vacuum cleaner;

in response to an indication of the dust container being filled beyond a threshold value, transmit a full dust container wireless signal to the construction tool to cause the construction tool to stop movement; and

subsequent to the construction tool stopping movement, stop suction.

6. The construction system of claim 5 , wherein the automated vacuum cleaner is further configured to:

store a position of a dust container emptying position; and

move to the dust container emptying position.

7. A method for operating a system for automated servicing of a construction tool by an automated vacuum cleaner, the construction tool being configured to produce dust and debris due to operation of the construction tool, the construction tool being a mobile construction tool comprising a means for propulsion of the mobile construction tool, the system comprising the construction tool and the automated vacuum cleaner, the method comprising:

transmitting a wireless signal comprising a servicing request by the construction tool;

receiving the wireless signal comprising the servicing request by the automated vacuum cleaner;

determining, by a vacuum cleaner controller of the automated vacuum cleaner:

a relative location based on a location of the construction tool in relation to a location of the vacuum cleaner by analyzing the servicing request, or

a relative orientation based on an orientation of the construction tool in relation to an orientation of the automated vacuum cleaner by analyzing the servicing request; and

relocating, by the vacuum cleaner controller, the automated vacuum cleaner based on the relative location or the relative orientation;

wirelessly connecting the automated vacuum cleaner to the construction tool upon reception of the servicing request from the construction tool, and

continuously monitoring and responsively moving by the automated vacuum cleaner to maintain a following position with the construction tool by changing location or orientation to collect the dust or debris generated by the construction tool.

8. The method of claim 7 further comprising approaching, by the automated vacuum cleaner, the construction tool in response to receipt of the service request and moving into the following position.

9. The method of claim 7 further comprising:

monitoring, by the automated vacuum cleaner, a level of dust collected in a dust container of the automated vacuum cleaner;

in response to an indication of the dust container being filled beyond a threshold value, transmitting, by the automated vacuum cleaner, a full dust container wireless signal to the construction tool; and

in response to receiving the full dust container wireless signal by the construction tool, stopping movement of the construction tool; and

subsequent to stopping movement of the construction tool, stopping suction by the automated vacuum cleaner.

10. The method of claim 9 further comprising:

storing a position of a dust container emptying position; and

moving the automated vacuum cleaner to the dust container emptying position.

11. The method of claim 7 further comprising using a location sensor or an orientation sensor to detect and avoid obstacles during movement of the automated vacuum cleaner.

12. The method of claim 7 further comprising detecting a position of a construction tool control device and ensuring that the vacuum cleaner does not remain, for more than a threshold duration of time, in any location that is in a line of sight between the construction tool control device and the construction tool.

13. A construction tool configured to be serviced by an automated vacuum cleaner, the construction tool comprising:

a controller;

a wireless transmitter connected to the controller; and

a location sensor or an orientation sensor;

wherein the controller is configured to control the wireless transmitter to transmit a location of the construction tool to the automated vacuum cleaner to enable relocation of the automated vacuum cleaner based on the location of the automated vacuum cleaner;

wherein the construction tool is a mobile construction tool and further comprises means for propulsion controlled by the controller.
