Abstract: A contactless power supply system includes a contactless power supply device and a power receiving device. Power is supplied from the contactless power supply device to the power receiving device while communication is performed therebetween. The power receiving device includes a power receiving coil unit, and a first communication unit that attaches information having continuity to data transmitted to the contactless power supply device. The contactless power supply device includes a power supply coil unit, a second communication unit, and a power supply control unit that, in a steady state where communication is performed between two communication units after the second communication unit begins receiving the data transmitted from the first communication unit, refers to information having continuity attached to the data, and if continuity has been lost, performs correction to increase the output value of the power from the power supply coil unit to the power receiving coil unit.

Abstract: A communication device 10 comprises a control unit 11b, a first communication unit 11, a second communication unit 12, and a communication control unit 11da. The control unit 11b acquires output signals from sensors 21a to 21d. The first communication unit 11 and the second communication unit 12 transmit the output signals acquired by the control unit 11b to a cloud server 31. The communication control unit 11da uses the first communication unit 11 to communicate with the cloud server 31 when the radio field strength of the signal transmitted from the first communication unit 11 to the cloud server 31 is over a specific threshold value, and switches from communication using the first communication unit 11 to communication using the second communication unit 12 when the radio field strength is at or below the specific threshold value.

Abstract: A communication system comprises a communication device that acquires output signals from sensors, a cloud server, a sensor, etc., and transmits these signals to a cloud server. The communication device has a control unit, a communication unit, and a communication control unit. The communication unit transmits the output signal acquired by the control unit to the cloud server. The communication control unit acquires the radio field strength of the output signal transmitted from the communication unit. The cloud server has a data input unit and a data analysis unit. The data input unit acquires data about the output signal and radio field strength from the communication unit. The data analysis unit analyzes the communication environment between the communication device and the cloud server on the basis of the radio field strength.
