Description

受電装置1は、有線インタフェースおよび無線インタフェースを備えたPoE規格に対応する無線通信装置である。例えば、受電装置1は、PoE規格に対応した少なくとも2つのLANポートを備える無線アクセスポイントであり、さらに通信端末10と無線インタフェースを介して無線通信リンク19により無線通信を行い、有線インタフェースを介して有線ケーブル18により周辺機器11と有線通信が行える。また、受電装置1は、有線インタフェースおよび無線インタフェースのどちらか一種類のインタフェースのみを備えていてもよい。ここで、有線インタフェースは、具体的にはUSB規格、HDMI(登録商標)規格、IEEE802.3規格に準拠したインタフェースなどである。また、無線インタフェースは、具体的にはIEEE802.11規格に準拠したインタフェースなどである。
The power receiving device 1 is a wireless communication device that has a wired interface and a wireless interface and that supports the PoE standard. For example, the power receiving device 1 is a wireless access point including at least two LAN ports compatible with the PoE standard, and further performs wireless communication with the communication terminal 10 via the wireless interface via the wireless communication link 19 and via the wired interface. The wired cable 18 enables wired communication with the peripheral device 11. The power receiving device 1 may include only one type of interface, a wired interface or a wireless interface. Here, the wired interface is, for example, an interface based on the USB standard, the HDMI (registered trademark) standard, or the IEEE802.3 standard. The wireless interface is, for example, an interface based on the IEEE 802.11 standard.

ステップS44にて、遮断部305は、ステップS4の通知をもとに、第1PHY回路23にデータ通信を一定時間、停止するように通知する。第1PHY回路23は、当該通知をもとに、データ通信を一定時間、停止する。以下に示すように、このデータ通信の停止は、上流の給電装置およびサーバPCに対し、応答を返さないことにより主経路の切り替えを知らしめるためである。
At step S44, the blocking unit 305, based on the notification of step S4 3, fixed time data communication to the 1PHY circuit 23 notifies to stop. Based on the notification, the first PHY circuit 23 suspends the data communication for a fixed time. As described below, the stop of the data communication is to notify the upstream power supply device and the server PC of the switching of the main route by not returning a response.

(まとめ)
従来のPoE受電による電源およびデータ通信の二重化システムにおいては、給電装置から受電装置にPoEによる給電を行っているときに1つの回線に電源障害(電力の授受ができない障害)が発生しても、当該システムが自動的(自律的に)に他方の経路に適切に切り替えることで給電経路を確保することが行われていた。しかし、当該システムでは、電源障害が発生した場合、自動的に回線を切替えることから、電源障害がいつ発生したかを知ることができず、システム管理者等が障害に気付かずにシステムを継続して使用した結果、もう一方の経路で新たな電源障害が発生した場合にはシステム全体に影響を及ぼしてしまう。また、従来システムにおいて、システム管理者等はサーバPCを介して障害通知を確認できるが、接続している給電装置までの間に障害が生じた場合、容易に障害を確認できるものの、給電装置に接続した受電装置で障害が発生した場合は、受電装置から障害が発生している旨の通知を受けない限りは障害を知り得ない。
(Summary)
In a conventional dual power supply and data communication system using PoE power reception, even when a power failure (a failure that cannot transfer power) occurs in one line while power is being supplied from the power supply apparatus to the power reception apparatus using PoE, The power supply route has been secured by the system automatically (autonomously) appropriately switching to the other route. However, in the system, when a power failure occurs, the line is automatically switched, so it is not possible to know when the power failure occurs, and the system administrator can continue the system without noticing the failure. As a result, if a new power failure occurs on the other path, it will affect the entire system. Also in the conventional system, the system administrator or the like can confirm the failure notification via the server PC, when a failure until the feeding device connected has occurred, although it can be confirmed easily disorders, feeding device If a failure occurs in the power receiving device connected to, the failure cannot be known unless the power receiving device notifies the power receiving device of the failure.

このような問題に対し、上述で説明した本発明は、特に、受電装置内の通常使用されるPoE受電回路部分に障害が発生した場合に、応答を停止させるという簡易な方法で電源障害発生を給電装置に認識させ、この通知をもとに給電装置あるいはその上流に位置するサーバPCは、受電装置の通常使用している経路に何らかの障害が発生したことを検知でき、例えば、その旨を接続しているシステム管理者等が使用する端末に通知できる。このようにして、システム管理者等は、早期にPoE受電による電源およびデータ通信の二重化システムの受電装置内の障害を認知でき、メンテナンスを行うことができるので、システムの信頼性向上に寄与する。
In response to such a problem, the present invention described above can prevent a power failure from occurring by a simple method of stopping the response, particularly when a failure occurs in the PoE power receiving circuit portion normally used in the power receiving device. feeding device is recognized, the notification based on the feed device or the server PC located upstream can detect that some failure occurs in the route being normal use of the power receiving device, for example, connected to that effect It can notify the terminal used by the system administrator. In this way, the system administrator or the like can recognize the failure in the power receiving device of the power supply and data communication duplication system due to PoE power reception and perform maintenance at an early stage, which contributes to improvement in system reliability.
