摘要： In a device management system (1) in which a plurality of devices (21) are managed by a management device (10) via a network (15), a device registration operation for registering the devices (21) in the management device (10) is assisted. A device-registration-operation assisting apparatus (2) includes an emission unit (26) of an electromagnetic wave, the emission unit (26) being integrated into or positioned near each of the plurality of devices (21), and a mobile terminal (40) to be carried by an operator. The mobile terminal (40) includes a receiving unit (41) that receives an electromagnetic wave, a display unit (42) that displays information on the device into or near which the emission unit from which the electromagnetic wave is emitted is integrated or positioned, and an input unit (43) that receives an input of registration information for registering the device displayed on the display unit in the device management system. The display unit (42) does not display the information of the device for which the registration information is input to the input unit, or changes display of the information.

摘要： A communication network system (90) includes a first transmission channel (50), a second transmission channel (60), a first device (70), a second device (20), and a third device (10). The second transmission channel (60) is different from the first transmission channel (50). The first device (70) is connected to the first transmission channel (50) and is not connected to the second transmission channel (60). The second device (20) is connected to the second transmission channel (60) and is not connected to the first transmission channel (70). The third device (10) electrically connects the first transmission channel (50) and the second transmission channel (60). The third device (10) does not transmit a short-circuit state occurring in one of the first transmission channel (50) and the second transmission channel (60) to a transmission channel other than the one of the first transmission channel (50) and the second transmission channel (60), thereby enabling communication between devices connected to the transmission channel other than the one.

摘要： In a network in which a plurality of devices are classified into a plurality of layers, in a case where communication independent of the layers and communication within the layers are performed through physical lines, the reliability of communication is improved. A physical first line (501) is connected to an outdoor unit (110) and a first indoor unit (121), which are first-layer devices, and a physical second line (502) is connected to a second indoor unit (122), which is a second-layer device. A first intermediary unit (150), which is a first intermediary device, includes a first filter (151) always connected to the first line (501) and the second line (502). The first intermediary unit (150) communicates with the outdoor unit (110) and the second indoor unit (122) via a first signal. The first filter (151) is installed so as not to attenuate a high-frequency first signal used for communication among the outdoor unit (110), the first indoor unit (121), the first intermediary unit (150), and the second indoor unit (122) and so as to attenuate a low-frequency second signal used for communication between the first intermediary unit 150 and the second indoor unit 122.

摘要： An indoor unit applicable to an air conditioner is configured to recognize physical connection between with an outdoor unit in a communication state suitable for each form of the air conditioner. An indoor unit (3) included in an air conditioner including an outdoor unit includes a power receiving circuit (PR2), a low-frequency transmission and reception circuit (306) as a first reception circuit, a high-frequency transmission and reception circuit (304) as a transmission and reception circuit, and an MCU (303) as a inner-controller. The low-frequency transmission and reception circuit (306) can receive a current signal transmitted from an outdoor unit (2) by using a current loop formed by a power line (L 1) included in power supply wiring (W1). Regarding a first communication state in which physical connection between with the outdoor unit (2) is recognized and a second communication state in which communication for operation of the air conditioner is performed between with the outdoor unit (2), the MCU (303) selects use of the low-frequency transmission and reception circuit (306) and the high-frequency transmission and reception circuit (304) in the first communication state and the second communication state.

摘要： Means is to be established for appropriately performing system recognition on devices connected to an identical system without recognizing a device of a different system as a device of the identical system in high-frequency communication. In a device network system, in a state in which a first device group is set in advance as a physically connectable system or in a state in which the first device group is recognized as a physically connectable system, in a case where the first device group or a second device detects occurrence of a state in which the second device outside the system is recognized as belonging to the system, the first device group or the second device causes the second device to leave the system. As a result, a network can be normally maintained even in high-frequency communication.

摘要： Means is to be established for appropriately performing system recognition on devices connected to an identical system without recognizing a device of a different system as a device of the identical system in high-frequency communication. In a device network system, an outdoor unit (101) selected from among all outdoor units (101, 102, 103) of a first network (10) performs a recognition process on the outdoor units (102, 103) and indoor units (104, 105, 106) of the first network (10). In the first network (10), communication between individual devices including the outdoor units (101, 102, 103) and the indoor units (104, 105, 106) is performed by using a high frequency, and the recognition process performed by the selected outdoor unit (101) uses a recognition signal having a low frequency.
