Abstract
If control periods at sensors are equal to each other, a control terminal transmits control commands intended for the sensors at a time to the sensors at the earliest control timing and the latest control timing among control timings at the sensors. If the control periods are different from each other, the control terminal transmits control commands intended for the sensors at a time to the sensors at the start timing and the end timing of the shortest control period. Further, if reception periods in data reception from a sensor is longer than a control period at the sensor, the control terminal transmits a control command to the sensor in response to data reception from the sensor.
