摘要:
A communication system for safe wireless control of an maneuverable object. A control unit includes an operator for operating the object and a receiver for receiving wireless information. A portable operating unit has a transmitter for transmitting wireless information. The information is divided in time slots, each including a data package. The receiver includes a detector for detecting in a time part of a time slot the presence of the data package and a calculator for calculating upon a reception failure the number of time parts having no presence of the data package following a time slot with presence of the data package. The control unit exercises a control command when a data package with a correct information has been received within a number of time parts just exceeding a full time slot.

A communication system for safe wireless control of an manoeuvrable object (3), comprising a control unit (1) having means for operating the object and receiving means for wireless information, and a portable operating unit (2) having sending means for wireless information, where said information is divided in time slots (ts), each containing a data package (21). The receiving means comprises detecting means for detecting in a time part (tp) of a time slot the presence of said data package and calculating means for calculating upon a reception failure the number of time parts having no presence of said data package following a time slot with presence of said data package. The control unit exercises a control command when a data package with a correct information has been received within a number of time parts just exceeding a full time slot.
摘要:
A robot controller including a control unit and a portable device (TPU) for teaching and manually operating the robot. The TPU includes safety equipment, a safety TPU-part having a first communication unit and a main TPU-part having a third communication unit. The control unit includes a safety control part having a second communication unit and a main control part having a forth communication unit. The first and second communication units form a first communication channel for transferring data from the TPU to the control unit. The third and fourth communication units form a second communication channel for transferring data between the TPU and the control unit. Each of the main TPU-part, safety TPU-part, main control part, and safety control part includes a processor for generating and/or handling the data. Each communication unit is connected to a network and forms a node in the network.

A robot controller including a control unit and a portable operating device (TPU) for teaching and manually operating the robot. The TPU includes safety equipment, a safety TPU-part having a first communication unit and a main TPU-part having a third communication unit. The control unit includes a safety control part having a second communication unit and a main control part having a forth communication unit. The first and second communication units are arranged such that they form a first communication channel for transferring communication data including information regarding the status of safety equipment from the TPU to the control unit. The third and fourth communication units are arranged such that they form a second communication channel for transferring general communication data between the TPU and the control unit. Each of the main TPU-part, the safety TPU-part, the main control part, and the safety control part includes a central processing unit adapted for generating and/or handling the communication data. Each of the communication units is connected to a network. Each of the communication units forms a node in the network.

摘要:
A transmitting node in an industrial wireless network transmits a first number of bits to a receiving node, where at least one bit is partitioned into segments and each segment is transmitted at a different frequency according to a frequency transmission scheme. The receiving node receives the number of bits, determines the quality of each segment of a received bit, collects quality determinations of segments, forms a quality measure for each frequency through combining quality determinations of the corresponding frequency, compares each quality measure with a quality measure criterion, determines at least one frequency that does not fulfill the quality measure criterion and informs the transmitting node about frequencies for which the corresponding quality measures do not fulfill the quality measure criterion. The transmitting node receives the information and updates the frequency transmission scheme.
