Patent number: 9930549Abstract: A method for communication between a wireless device node in a wireless sensor network (WSN) and control apparatus or control processes of an industrial control system is used to determine a method of radio transmission which provides a greater or a lesser measure of transmission quality between nodes. Thus a transmitter node measures a transmission quality metric of at least one packet received from two or more different switching branches, identifies which of the two or more switching branches has the greater transmission quality metric, distributes data packets with a first priority to the switching branch with the greater transmission quality metric, and transmits data packets with the first priority such as real-time data on the switching branch with the greater transmission quality metric. A wireless node, a sensor network system and a computer program for carrying out the method are described.Type: GrantFiled: January 25, 2013Date of Patent: March 27, 2018Assignee: ABB RESEARCH LTD.Inventors: Johan Åkerberg, Mikael Gidlund

Patent number: 9750083Abstract: A method for communication between a wireless device node in a wireless sensor network and control apparatus or control processes of an industrial control system. The wireless network includes a plurality of device nodes and at least one gateway. The method includes receiving at a gateway an aggregated data packet or a final address in the ICS. The gateway processes the data packet, detects that it is an aggregated data packet and reconstructs the original data packets contained therein. The gateway then sends each of the original data packets as standard data packets to the intended final address in the ICS. In other aspects of the invention a method, system and a computer program for carrying out the method are described.Type: GrantFiled: December 4, 2012Date of Patent: August 29, 2017Assignee: ABB Research Ltd.Inventors: Mikael Gidlund, Tomas Lennvall, Jonas Neander

Patent number: 9451498Abstract: A method for communication in a wireless sensor network of an industrial control system. The network includes a plurality of device nodes and at least one gateway. The method includes aggregating in at least one wireless device data originating from at least two data packets. The method includes receiving at a first node at least one first data packet for a first destination address and aggregating data from the at least one data packet with data from at least one second data packet, intended for the same first destination address, forming an aggregated data packet and sending the aggregated data packet to another node or to said gateway. In other aspects of the invention a method, system and a computer program for carrying out the method are described.Type: GrantFiled: September 14, 2012Date of Patent: September 20, 2016Assignee: ABB Research Ltd.Inventors: Mikael Gidlund, Tomas Lennvall, Jonas Neander

Patent number: 9338058Abstract: A network manager device in an industrial wireless network sends a network investigating message to other network nodes for processing and forwarding through the network, the message including a message weight. A wireless communication device providing a node in the network receives the message from another network node, determines a communication weight based on the quality of communication, adds the communication weight to the message weight and compares the sum with the node weight. If the sum is lower than the node weight, it is set as new node weight and as new message weight, whereupon the changed message is sent to other nodes in the network. The network manager device maps the topology of the network based on updated node weights, sets a communication scheduling scheme based on the mapped topology and informs the network nodes of the scheme.Type: GrantFiled: May 17, 2013Date of Patent: May 10, 2016Assignee: ABB RESEARCH LTDInventors: Mikael Gidlund, Johan Åkerberg, Pang Zhibo, Kan Yu
