Abstract
In a control device (10), a determination unit (11) determines “a plurality of collision-occurrence-estimated devices” for which “transmission collision” is estimated to occur due to overlapping of transmission schedule timings among the plurality of communication devices. A transmission control unit (12) executes transmission control of transmitting, to each of some of the plurality of collision-occurrence-estimated devices, each of a plurality of “timing distribution control signals” for distributing transmission timings of the plurality of collision-occurrence-estimated devices determined by the determination unit (11).
Claims12
A control device which controls transmission timings of a plurality of communication devices existing under a network device and each transmitting a data signal toward the network device at a transmission period being associated with each of the communication devices, the control device comprising:
- hardware including at least one processor and at least one memory;
- determination unit implemented at least by the hardware and that determines a plurality of collision-occurrence-estimated devices for which transmission collision is estimated to occur due to overlapping of transmission schedule timings among the plurality of communication devices;
- and
- transmission control unit implemented at least by the hardware and that executes transmission control of transmitting, to each of some of the plurality of collision-occurrence-estimated devices, each of a plurality of timing distribution control signals for distributing transmission timings of the plurality of collision-occurrence-estimated devices.
A control method of controlling transmission timings of a plurality of communication devices existing under a network device and each transmitting a data signal toward the network device at a transmission period being associated with each of the communication devices, the control method comprising:
- determining a plurality of collision-occurrence-estimated devices for which transmission collision is estimated to occur due to overlapping of transmission schedule timings among the plurality of communication devices;
- and
- executing transmission control of transmitting, to each of some of the plurality of collision-occurrence-estimated devices, each of a plurality of timing distribution control signals for distributing transmission timings of the plurality of collision-occurrence-estimated devices.
A non-transitory computer-readable medium storing a control program causing a control device which controls transmission timings of a plurality of communication devices existing under a network device and each transmitting a data signal toward the network device at a transmission period being associated with each of the communication devices, to execute processing of
- determining a plurality of collision-occurrence-estimated devices for which transmission collision is estimated to occur due to overlapping of transmission schedule timings among the plurality of communication devices, and
- executing transmission control of transmitting, to each of some of the plurality of collision-occurrence-estimated devices, each of a plurality of timing distribution control signals for distributing transmission timings of the plurality of collision-occurrence-estimated devices.
