COMMUNICATION DEVICE, INDUSTRIAL MACHINE, AND COMMUNICATION-QUALITY-DETERMINING METHOD
The present invention provides a communication device, an industrial machine, and a communication-quality-determining method. A communication device is provided with: a transmission unit for transmitting a serial signal; a first phase difference determination unit for determining a first phase difference which is a phase difference between a first reference clock signal having the same period as the 1-bit period of a serial transmission signal which is the serial signal transmitted from the transmission unit and an edge of the serial transmission signal transmitted from the transmission unit; and a determination unit for determining that there is an abnormality with the serial transmission signal transmitted from the transmission unit when the first phase difference exceeds a first phase difference threshold.
VARIABLE-LEVEL INTEGRITY CHECKS FOR COMMUNICATIONS IN PROCESS CONTROL ENVIRONMENTS
The described methods and systems enable process control devices to transmit and receive device variable values in a manner that enables the receiving device to verify the integrity of the received values on a variable-by-variable basis. To facilitate verification of integrity, any desired number of variables in a message may have a data integrity check in the message. For each received value that has a data integrity check, the receiving device can calculate its own data integrity check based on the received value and a seed (known to both the transmitting and receiving devices), which it can then compare to the received data integrity check to verify if the received value has been altered during communication.
ELECTRONIC APPARATUS, ELECTRONIC SYSTEM, METHOD, AND COMPUTER READABLE MEDIUM
According to one embodiment, an electronic apparatus instructs an operation of at least a part of a control target device via wireless communication. The electronic apparatus comprises a processor configured to acquire communication quality information of the wireless communication between the electronic apparatus and the control target device, acquire first information indicating a degree or a risk that can be caused by the operation, and generate a control signal instructing the operation based on the communication quality information and the first information.
Variable-level integrity checks for communications in process control environments
The described methods and systems enable process control devices to transmit and receive device variable values in a manner that enables the receiving device to verify the integrity of the received values on a variable-by-variable basis. To facilitate verification of integrity, any desired number of variables in a message may have a data integrity check in the message. For each received value that has a data integrity check, the receiving device can calculate its own data integrity check based on the received value and a seed (known to both the transmitting and receiving devices), which it can then compare to the received data integrity check to verify if the received value has been altered during communication.
Closed-loop control system for robotic operation
Example systems and methods may allow for closed-loop control of robotic operation. One example method includes receiving input data that identifies data sources to monitor and indicates adjustments to make in response to deviations by at least one of the data sources from at least one predicted state during subsequent execution of sequences of operations by robotic devices, receiving data streams from the data sources during execution of the sequences of operations by the robotic devices, identifying a deviation by one of the data sources from a predicted state for which the received input data indicates adjustments to the sequences of operations for the robotic devices, providing instructions to the robotic devices to execute the adjusted sequences of operations, and providing instructions to a second computing device to update a visual simulation of the robotic devices based on the adjusted sequences of operations.
Technique for performing QoS control in a cloud robotics system
A technique for performing Quality of Service, QoS, control regarding control messages communicated from a robot controller to a robot via a mobile communication network in a cloud robotics system is disclosed. A method implementation of the technique comprises triggering applying a mapping of control messages communicated from the robot controller to the robot to QoS classes among a plurality of data session related QoS classes supported by the mobile communication network for transmission of traffic via the mobile communication network, wherein each of the control messages is mapped to a respective QoS class depending on a Quality of Control, QoC, tolerance associated with the respective control message.
