  • Patent number: 9843506
    Abstract: In a distributed control system including a central communication device, terminal communication devices to which target devices to be controlled are connected, and a network including multiple communication paths connecting the central communication device and terminal communication devices, each terminal communication device includes a calculation input/output performance storage unit storing input/output performance of a calculation unit for controlling the target devices to be controlled and a control input/output performance storage unit storing the performance of the input/output control units of the target devices to be controlled, and the central communication device collects input/output performance information previously stored in these storage units, determines communication paths of the terminal communication units and a packet division method in such a manner that an amount of a communication data of a network and response performance requested of the distributed control system are satisfied, on

  • Publication number: 20170094200
    Abstract: An image processing apparatus performs fast image transfer of an image sensor and can easily satisfy required performance of image transfer. The image processing apparatus includes a sensor and a processing unit, the sensor obtains a first image including a recognition target at a first time, obtains a second image including the recognition target at a second time later than the first time, and obtains a third image including the recognition target at a third time later than the second time, and the processing unit determines first setting information of the sensor from the first image and the second image so as to satisfy a predetermined condition when the third image is obtained. Furthermore, the first setting information includes a dimension of the third image and a frame rate at the time of obtaining the third image.
