Abstract
A method and system are disclosed for localization in an industrial wireless sensor network by identifying a sensor node of a field device for localization, and determining the location information of the sensor node associated with the field device. The determined location information is stored in the field device, in one or more modules of the wireless network management component, and/or an operator portal. Operation can be indicated upon the joining of the field device into the network or during the commissioning of the industrial wireless sensor.
Claims10
A method for localization in an industrial wireless sensor network having one or more field devices, an operator portal, and/or a wireless network management component including one or more modules such as a network manager, a security manager, access points, and/or gateways, the method comprising:
- identifying a sensor node of a field device for localization by a detection means being the field device, or by one or more modules of the wireless network management component, by a commissioning and configuration unit, by one or more field devices co-located with the field device in the industrial wireless network, and/or by a hand held device;
- determining location information of the sensor node associated with the field device by a determining means having tools configured in one or more modules of the wireless network management component in the field device, or the commissioning and configuration unit, and/or in the operator portal;
- and
- storing the determined location information in the field device, in the operator portal, and/or in one or more modules of the wireless network management component.
A system for localization in an industrial wireless sensor network, the system comprising:
- one or more field devices which are indoor and/or outdoor;
- a wireless network management component including one or more modules;
- an operational portal aiding an operator to operate the network;
- and
- means for adapting to and/or configured to function using one or more techniques and/or tools of selected from a group consisting of GPS, RFID, radio frequency beacons, sensor node signal strength, centralized node distance information, time of arrival, and an initial deployment plan of a wireless sensor.
