COMMUNICATION APPARATUS, COMMUNICATION METHOD, AND COMPUTER READABLE MEDIUM

摘要

A gateway apparatus (103) receives a request frame transmitted from a system controller (101) to an indoor unit 1 (111), and determines whether a sensor specified in the request frame is a sensor 1-A (121) which is connected with the indoor unit 1 (111) or a sensor 1-B (123) which is not connected with the indoor unit 1 (111). When the sensor specified in the request frame is the sensor 1-B (123), the gateway apparatus (103) acquires a measurement value from the sensor 1-B (123), and responds to the system controller (101) with the acquired measurement value of the sensor 1-B (123).

主权项

1. A communication apparatus included in a network in which a device and a collection apparatus to collect a measurement value of a physical quantity used by the device are connected with each other, the communication apparatus comprising:
processing circuitry to: receive a measurement value transmission request which has been transmitted from the collection apparatus to the device, and specifies either of a connection sensor and a non-connection sensor and requests the device to transmit a measured value of the sensor specified to the collection apparatus, the connection sensor measuring a physical quantity used by the device and being connected to the device, the non-connection sensor measuring a physical quantity used by the device and not being connected to the device; determine whether the non-connection sensor is specified in the measurement value transmission request; acquire, when it has been determined that the non-connection sensor is specified in the measurement value transmission request, a measurement value of the non-connection sensor from the non-connection sensor; and transmit, to the collection apparatus, the acquired measurement value of the non-connection sensor in response to the measurement value transmission request.
