| 摘要 |
A data communication system includes a plurality of sensor initiators, each of which has first and second antennas; a communication control module and a plurality of sensor communication modules. The communication control module is connected with the plurality of sensor initiators through a LAN and is configured to control the plurality of sensor initiators such that a first electromagnetic wave signal for a command data signal is transmitted through the first antennas. Each of the plurality of sensor communication modules includes at least a sensor and third and fourth antennas. The sensor communication module is configured to receive the first electromagnetic wave signal for the command data signal by a resonance antenna as the third antenna to generate a reception voltage signal, to adjust a damping time of the reception voltage signal, and to transmit a measurement data signal obtained from the sensor to the communication control module from the fourth antenna by a second electromagnetic wave signal through the second antenna in response to the command data signal obtained from the reception voltage signal.
