Abstract

A hazard management system for a construction site is provided, including a hazard sensor unit, a control unit, and a piece of construction equipment, wherein the hazard sensor unit is configured to determine at least one hazard measured value of the construction site for at least one hazard, wherein the control unit is configured to evaluate the hazard measured value, and wherein the control unit is configured to control the construction equipment to switch the construction equipment on and/or off and/or to set a working parameter, and/or to provide a user of the hazard management system with a control signal for controlling the construction equipment. A hazard sensor unit is also provided.

First claim

1 . A hazard sensor unit for a hazard management system for use on a construction site, wherein the hazard sensor unit is configured to determine at least one measured hazard value of the construction site for at least one hazard, and wherein the hazard sensor unit of is configured to detect a usage type of the hazard sensor unit.

2 . The hazard sensor unit according to claim 1 , wherein the hazard sensor unit is configured to detect a space-related and/or a person-related use of the hazard sensor unit as the usage type of the hazard sensor unit.

3 . The hazard sensor unit according to claim 1 , wherein the hazard sensor unit has an acceleration sensor, wherein the hazard sensor unit of is configured to determine the usage type with aid of the acceleration sensor.

4 . The hazard sensor unit according to claim 1 , wherein the hazard sensor unit is configured to record as the at least one hazard, a dust.

5 . The hazard sensor unit according to claim 1 , wherein the hazard sensor unit is configured to determine at least one of a particle concentration, a particle size, a particle distribution or a chemical particle composition as the at least one measured hazard value.

6 . The hazard sensor unit according to claim 1 , wherein the hazard sensor unit has an optical sensor unit for determining the at least one measured hazard value.

7 . The hazard sensor unit according to claim 1 , wherein the hazard sensor unit has a position detector for recording the position of the hazard sensor unit.

8 . The hazard sensor unit according to claim 1 , wherein the hazard sensor unit is configured to distinguish at least the usage modes of “arranged on a person at a construction site,” “deposited at a fixed location at a construction site” and/or “in motion at a construction site independently of a person” as the usage type.

9 . The hazard sensor unit according to claim 1 , wherein the hazard sensor unit can be operated with a glove.

10 . A hazard management system for a construction site comprising
a hazard sensor unit according to claim 1 , wherein the hazard sensor unit is configured to determine at least one measured hazard value of the construction site for at least one hazard, wherein the hazard sensor unit is configured to detect a usage type of the hazard sensor unit, a control unit, and a construction device, wherein the control unit is configured to evaluate the at least one measured hazard value, and wherein the control unit is configured to control the construction device.

11 . The hazard management system according to claim 1 , wherein the control unit is configured to control the construction device when the at least one measured hazard value exceeds a first limit value.

12 . The hazard management system according to claim 10 , the construction device is or at least comprises a suction device, a blowing device and/or a filtering device.

13 . The hazard management system according to claim 10 , wherein the construction device is a construction robot or a hand-held machine tool or comprises the construction robot or the hand-held machine tool.

14 . The hazard management system according to claim 10 , wherein the at least one measured hazard value is a dust-related characteristic value.

15 . The hazard management system according to claim 10 , wherein the hazard management system is configured to determine a malfunction and/or an operating state of an element of the hazard management system as a function of the at least one measured hazard value.

16 . The hazard management system according to claim 10 , wherein the control unit comprises at least one cloud-based computer unit.

17 . The hazard sensor unit according to claim 4 , wherein the dust is an alveolar dust, a silica-based and/or a wood-based dust.

18 . The hazard sensor unit according to claim 9 , wherein the hazard sensor unit can be operated with a construction glove.

19 . The hazard management system according to claim 10 , wherein the hazard sensor unit is configured to detect a space-related and/or a person-related use of the hazard sensor unit.

20 . The hazard management system according to claim 10 , wherein the
wherein the control unit is configured to control the construction device to switch the construction device on, to switch it off and/or to set a working parameter, in particular its working power, and/or to give a user of the of the hazard management system a control signal for controlling the construction device.
