A communication system includes housing equipment, a relaying apparatus that communicates with the housing equipment, and a management device that communicates with the relaying apparatus via a communication network. The management device is configured to store user identification information sent from a communication terminal that communicates with the management device via the communication network, and association information associated with identification information of the relaying apparatus sent from the relaying apparatus, and permit first communication via the management device between the communication terminal and the relaying apparatus that have been associated with each other in the association information. After the first communication is permitted, if no communication is performed from the relaying apparatus or the communication terminal to the management device during a predetermined first period, the management device is configured to prohibit the first communication in and after the first period.

Communication system

A communication adapter for collecting various kinds of information from a water-heating system and providing the information to an administration center via a wireless LAN router functions as an access point for providing a direct wireless communication with a smartphone; in response to a request from the smartphone via the direct wireless communication, it provides pairing authentication information to the smartphone; in response to a request from the smartphone, it initializes the wireless LAN connection information for the wireless LAN router to disconnect the wireless link to the wireless LAN router; and, when the wireless LAN connection information is set by its WPS function, it establishes a wireless link to the wireless LAN router and transmits the pairing authentication information to the administration center via the wireless LAN router.

A communication adapter for transmitting information about a system being monitored, such as a multi-water-heater system, to a remote management apparatus and collecting information about the system being monitored allows the location of an abnormality in communication to be easily identified even when the adapter is communicably connected to the remote management apparatus via a communication relay unit, thereby improving the reliability of the information collection process. The communication adapterincludes a function for detecting an abnormality in communication between the communication adapterand system being monitored, a function for detecting an abnormality in communication between the communication adapterand communication relay unit, and a function for detecting an abnormality in communication between the communication relay unitand remote management apparatus

A method for attenuating aerodynamic noise from a landing gear may include researching a start point of a shear layer as a flow field characteristic of a region in the vicinity of an original shape of the landing gear, and adding a plate-shaped object in the vicinity of the start point, changing the start point to an edge portion of the plate-shaped object to make the shear layer farther from the original shape. Another method for attenuating aerodynamic noise from a landing gear may include researching a static pressure and an airflow velocity in a region in the vicinity of the landing gear as a flow field characteristic of the region, and adding a plate-shaped object covering a surface of the landing gear which is different from a surface facing an upstream side in an airflow direction, increasing the static pressure in the region to reduce the airflow velocity.
