Abstract
A communication device has: a sensor configured to output sensing data; a count signal communication part configured to count a count signal received from a control device directly or via another communication device and transmit the counted count signal and to store a value of the received count signal; and a data communication part configured to transmit the sensing data outputted by the sensor or the sensing data received from another communication device, in correspondence with the stored value of the count signal.
Claims6
A communication device, comprising:
- a sensor configured to output sensing data;
- a communication circuit configured to
- count a count signal received from a control device directly or via
- another communication device and transmit the counted count signal and to store a value of the received count signal;
- and
- transmit the sensing data outputted by the sensor or the sensing data received from the another communication device, in correspondence with the stored value of the count signal, wherein when the stored value of the count signal is smaller than a threshold value set in advance, the communication of circuit is configured to transmit, with high priority, the sensing data received from another communication device instead of transmission of sensing data outputted by the sensor.
A communication device, comprising:
- a sensor configured to output sensing data;
- a communication circuit configured to
- count a count signal received from a control device directly or via
- another communication device and transmit the counted count signal and to store a value of the received count signal;
- and
- transmit the sensing data outputted by the sensor or the sensing data received from the another communication device, in correspondence with the stored value of the count signal, wherein when the stored value of the count signal is smaller than a first threshold
- value set in advance, the communication circuit is configured to not perform transmission of the sensing data outputted from the sensor but transmit the sensing data received from the another communication device, and
- when the stored value of the count signal is larger than a second threshold value set in advance, the communication circuit is configured to transmit one of:
- the sensing data outputted by the sensor and the sensing data received from the another communication device.
A communication system, comprising:
- a plurality of communication devices;
- and
- a control device,
- wherein each of the plurality of communication devices comprises:
- a sensor configured to output sensing data;
- a communication circuit configured to
- count a count signal received from the control device directly or via another communication device and transmit the counted count signal and to store a value of the received count signal;
- and
- transmit the sensing data outputted by the sensor or the sensing data received from another communication device, in correspondence with the stored value of the count signal, wherein
- when the stored value of the count signal is smaller than a threshold value set in advance, the communication circuit is configured to transmit, with high priority, the sensing data received from the another communication device instead of transmission of sensing data outputted by the sensor.
A control method of a communication device which has a sensor outputting sensing data, the method comprising:
- counting a count signal received from a control device directly or via another communication device to transmit the counted count signal and storing a value of the received count signal;
- and
- when the stored value of the count signal is smaller than a threshold value set in advance, transmitting, with high priority, the sensing data received from the another communication device instead of transmission of sensing data outputted by the sensor.
