Abstract
In a communication system in which a plurality of master stations wirelessly communicate with a plurality of slave stations in a predetermined cycle, each of the plurality of slave stations being associated with one of the plurality of master stations, and the communication system includes: an allocation processor that allocates the plurality of master stations respectively to a plurality of temporal intervals resulting from time-division of the predetermined cycle, in a predetermined channel; and a communication processor that, in each of the plurality of temporal intervals, causes the master station to communicate with a plurality of slave stations associated with the master station, within that temporal interval.
Claims15
A communication system in which a plurality of master stations wirelessly communicates with a plurality of slave stations in a predetermined cycle, a plurality of first slave stations of the plurality of slave stations being associated with a first master station of the plurality of master stations, the communication system comprising:
- an allocation circuit that allocates the first master station to a first temporal interval of a plurality of temporal intervals resulting from a time-division of the predetermined cycle in a predetermined channel;
- and
- a communication circuit that outputs, to the first master station, an instruction for transmitting transmission data, including command information for causing a predetermined process to be executed and identification information of a plurality of second slave stations, among the plurality of the first slave stations, that is to execute the command information, so as to cause the first master station to transmit the transmission data to the plurality of first slave stations within the first temporal interval,
- the first master station transmits the transmission data to the plurality of first slave stations within a data transmission period in the first temporal interval, and
- each of the plurality of second slave stations transmits an acknowledgment, for the transmission data, to the first master station, at a different time in the first temporal interval, within a response reception period after the data transmission period.
A communication method in which a plurality of master stations wirelessly communicates with a plurality of slave stations in a predetermined cycle, a plurality of first slave stations of the plurality of slave stations being associated with a first master station of the plurality of master stations, the communication method comprising:
- allocating the first master station to a first temporal interval of a plurality of temporal intervals resulting from a time-division of the predetermined cycle in a predetermined channel;
- and
- outputting, to the first master station, an instruction for transmitting transmission data, including command information for causing a predetermined process to be executed and identification information of a plurality of second slave stations, among the plurality of first slave stations, that is to execute the command information, so as to cause the first master station to transmit the transmission data to the plurality of first slave stations within the first temporal interval, wherein
- the first master station transmits the transmission data to the plurality of first slave stations within a data transmission period in the first temporal interval, and
- each of the plurality of second slave stations transmits an acknowledgment, for the transmission data, to the first master station, at a different time in the first temporal interval, within a response reception period after the data transmission period.
A non-transitory computer-readable recording medium recording a communication program by which a plurality of master stations wirelessly communicates with a plurality of slave stations in a predetermined cycle, a plurality of first slave stations of the plurality of slave stations being associated with a first master station of the plurality of master stations, the communication program causing one or more circuits to perform:
- allocating the first master station to a first temporal interval of a plurality of temporal intervals resulting from a time-division of the predetermined cycle in a predetermined channel;
- and
- outputting, to the first master station, an instruction for transmitting transmission data, including command information for causing a predetermined process to be executed and identification information of a plurality of second slave stations, among the plurality of first slave stations, that is to execute the command information, so as to cause the first master station to transmit the transmission data to the plurality of first slave stations within the first temporal interval, wherein
- the first master station transmits the transmission data to the plurality of first slave stations within a data transmission period in the first temporal interval, and
- each of the plurality of second slave stations transmits an acknowledgment, for the transmission data, to the first master station, at a different time in the first temporal interval, within a response reception period after the data transmission period.
