Abstract

A blower filter device includes a blower unit that draws and delivers ambient air; a filter unit that filters a harmful substance, or a filter coupling to couple and uncouple the filter unit. A control unit is configured to actuate the blower unit, to determine an operating state of the blower filter device and/or other respirator system components and/or a respirator system ( 100 ) as a whole and to generate an alarm if a determined operating state indicates a disturbance. An output unit is configured to receive the alarm from the control unit and to output the alarm. A communication interface ( 228 ) is configured for wireless network integration and to transmit the alarm via the network ( 238 ). A respirator system ( 100 ) with such a blower filter device, an operational infrastructure ( 300 ) with such a respirator system, as well as a method of blower filter operation and operational infrastructure monitoring are provided.

First claim

1 . A blower filter device for a respirator system, the blower filter device comprising:
a blower unit configured to draw in and deliver ambient air; a filter unit configured to filter at least one harmful substance out of the ambient air drawn in and delivered, or a filter coupling for coupling and uncoupling such a filter unit, a control unit configured to actuate the blower unit, to determine an operating state of the blower filter device or to determine an operating state of other components of the respirator system or to determine an operating state of the respirator system as a whole or to determine an operating state of any combination of the blower filter device other components of the respirator system and the respirator system as a whole and to generate an alarm based on a determined operating state indicating a disturbance; an output unit configured to receive the alarm from the control unit and to output the alarm; a communication interface configured to be wirelessly integrated in a network and to transmit the alarm to other participants of the network.

2 . A blower filter device in accordance with claim 1 , wherein the communication interface is further configured to receive alarms from other participants of the network.

3 . A blower filter device in accordance with claim 2 , wherein the output unit is further configured to output alarms received from other participants of the network.

4 . A blower filter device in accordance with claim 2 , wherein the output unit is configured to output alarms differently according to origin or alarm type or both alarm origin and alarm type.

5 . A blower filter device in accordance with claim 1 , wherein the communication interface is configured to operate with at least one wireless technology and with a corresponding protocol, which are selected from the group that comprises Bluetooth, ZigBee, Ant and WLAN.

6 . A blower filter device in accordance claim 1 , wherein the communication interface has a gateway function in order to transmit received messages to other participants.

7 . A blower filter device in accordance claim 1 , wherein the blower filter device is configured such that the blower filter device can be worn on a body of a user or on clothing of the user or on a belt of the user.

8 . A respiratory protection system, comprising:
a headpiece -configured to be worn on the head of a person; a blower filter device configured to deliver and filter ambient air; and a connection unit pneumatically coupling the headpiece with a delivery side of the blower filter device, the blower filter device comprising: a blower unit configured to draw in and deliver ambient air; a filter unit configured to filter at least one harmful substance out of the ambient air drawn in and delivered, or a filter coupling for coupling and uncoupling the filter unit; a control unit configured to actuate the blower unit, to determine an operating state of the blower filter device or to determine an operating state of other components of the respirator system or to determine an operating state of the respirator system as a whole or to determine an operating state of any combination of the blower filter device, other components of the respirator system and the respirator system as a whole and to generate an alarm based on a determined operating state indicating a disturbance; an output unit configured to receive the alarm from the control unit and to output the alarm; and a communication interface configured to be wirelessly integrated in a network and to transmit the alarm to other participants of the network.

9 . A respiratory protection system in accordance with claim 8 , wherein the headpiece is a helmet, a fixed or inflatable hood, or a gas mask.

10 . Operational infrastructure, comprising:
a wireless network; at least one respirator system comprising: a headpiece configured to be worn on the head of a person; a blower filter device configured to deliver and filter ambient air; and a connection unit pneumatically coupling the headpiece with a delivery side of the blower filter device, the blower filter device comprising: a blower unit configured to draw in and deliver ambient air; a filter unit configured to filter at least one harmful substance out of the ambient air drawn in and delivered, or a filter coupling for coupling and uncoupling the filter unit; a control unit configured to actuate the blower unit, to determine an operating state of the blower filter device or to determine an operating state of other components of the respirator system or to determine an operating state of the respirator system as a whole or to determine an operating state of any combination of the blower filter device, other components of the respirator system and the respirator system as a whole and to generate an alarm based on a determined operating state indicating a disturbance; an output unit configured to receive the alarm from the control unit and to output the alarm; and a communication interface configured to be wirelessly integrated in a network and to transmit the alarm to other participants of the network, wherein the wireless network is adapted to the communication interface of the blower filter device of the at least one respirator system.

11 . Operational infrastructure in accordance with claim 10 , further comprising at least one additional participant, which is selected from the group comprising:
a monitoring units; an alarm generator; and a measuring unit, wherein each participant has a wireless communication interface, which is configured to become integrated in the wireless network and to transmit alarms to all or selected participants or to receive alarms from all or selected participants or to both transmit alarms to all or selected participants and to receive alarms from all or selected participants.

12 . A method of operating a blower filter device for a respirator system, the method comprising the steps of:
providing the blower filter device, the blower filter device comprising: a blower unit configured to draw in and deliver ambient air; a filter unit configured to filter at least one harmful substance out of the ambient air drawn in and delivered, or a filter coupling for coupling and uncoupling the filter unit; a control unit configured to actuate the blower unit, to determine an operating state of the blower filter device or to determine an operating state of other components of the respirator system or to determine an operating state of the respirator system as a whole or to determine an operating state of any combination of the blower filter device, other components of the respirator system and the respirator system as a whole and to generate an alarm based on a determined operating state indicating a disturbance; an output unit configured to receive the alarm from the control unit and to output the alarm; and a communication interface configured to be wirelessly integrated in a network and to transmit the alarm to other participants of the network; determining an operating state of the blower filter device or of other components of the respirator system or of the respirator system as a whole or any combination of the blower filter device, other components of the respirator system and the respirator system as a whole; generating an alarm if the determined operating state indicates a disturbance; outputting the alarm; and transmitting the alarm via a network to other participants of the network by wireless communication.
