Document Type and Number:
Japanese Patent JP2023039146
Kind Code:
A
Abstract:
To provide a communication device which makes a communication load between a center device and the communication device difficult to increase, a communication method, and a communication system.SOLUTION: A communication device 1 comprises a communication unit 11, a storage unit 16, and a control unit 15. The communication unit 11 transmits a telegraphic message D to a center device 2 and receives a response R from the center device 2. The storage unit 16 stores a transmission interval ΔT which is a time interval in which the center device 2 can transmit the response R to the communication unit 11. The control unit 15 controls the communication unit 11 so as to transmit a first telegraphic message D1 to the center device 2 and receive a first response R1 from the center device 2, and acquires a response reception time which is a time in which the communication unit 11 receives the first response R1 from the center device 2. When causing the communication unit 11 to transmit a second telegraphic message D2 after acquiring the response reception time, the control unit 15 determines a time Tb in which the second telegraphic message D2 is transmitted based on the transmission interval ΔT and the response reception time.SELECTED DRAWING: Figure 7
