このように、前記特許文献1乃至3に記載された発明にあっては、雨滴又は雨を検知するセンサ部と、その信号を処理する回路との接続及び前記センサ部へ電源を供給する手段が配線によって接続されており、これを物干し等へ適用する場合にあっては、ベランダ等の物干しとは別の位置に配線接続して設置する必要がある。つまり、雨滴又は雨を検知するセンサ部は、その配線部分がベランダ等における作業に支障のないように行う必要があり、設置場所に制限を受けるという欠点があった。   As described above, in the inventions described in Patent Documents 1 to 3, the connection between the sensor unit that detects raindrops or rain and the circuit that processes the signal, and means for supplying power to the sensor unit are provided. When they are connected by wiring and are applied to clothes drying etc., it is necessary to install them by wiring connection at a position different from clothes drying such as a veranda. In other words, the sensor unit for detecting raindrops or rain has to be performed so that the wiring portion does not hinder the work on the veranda or the like, and there is a disadvantage that the installation location is limited.

本発明は従来の前記課題に鑑みてこれを改良除去したものであって、雨滴又は雨を検知するセンサ部と、その信号を処理する回路部とが無線で接続された技術を提供せんとするものである。   The present invention is an improvement and removal in view of the conventional problems described above, and provides a technology in which a sensor unit that detects raindrops or rain and a circuit unit that processes the signal are connected wirelessly. Is.

而して、前記課題を解決するために本発明が採用した請求項1の手段は、無線電波を受信するアンテナと、無線電波を受信して電源の供給を受け、この電源を利用してデータをアンテナから送信するタグICと、データの送信をON/OFF制御するスイッチとから成る無線タグを配設し、前記スイッチの二つの電極を離間させて雨滴を感知する位置に配設し、雨滴によって前記電極間が短絡するようにしたことを特徴とする雨検知用の無線タグである。   Thus, the means of claim 1 employed by the present invention to solve the above-described problems is an antenna for receiving radio waves, receiving radio waves and receiving power supply, and using this power source for data Wireless tag comprising a tag IC that transmits a signal from an antenna and a switch for ON / OFF control of data transmission, the two electrodes of the switch are spaced apart from each other, and are disposed at a position to detect raindrops. The rain detection wireless tag is characterized in that the electrodes are short-circuited.

本発明が採用した請求項2の手段は、無線タグが物干し具に設置されている請求項1に記載の雨検知用の無線タグである。   According to a second aspect of the present invention, the wireless tag for rain detection according to the first aspect is provided, wherein the wireless tag is installed on the clothesline.

請求項1の発明にあっては、スイッチの二つの電極間に雨滴が付着し、これが短絡することによってスイッチがON動作し、アンテナ回路が形成されて当該アンテナがリーダ側から発信された無線電波を受信する。これにより、タグICに電源が供給され、当該電源を利用してタグICに保存されていたデータがアンテナを通じて送信される。この場合のデータは、雨滴又は雨を検知した旨の内容であり、必要に応じて光,音又は電波等で通知することができる。   In the first aspect of the present invention, raindrops adhere between the two electrodes of the switch, and when this is short-circuited, the switch is turned on, an antenna circuit is formed, and the antenna transmits the radio wave from the reader side. Receive. As a result, power is supplied to the tag IC, and data stored in the tag IC is transmitted through the antenna using the power. The data in this case is content indicating that raindrops or rain has been detected, and can be notified by light, sound, radio waves, or the like as necessary.

請求項2の発明にあっては、無線タグを物干し竿や放射状に展開する蛸足状等のその他の物干し具に設置しており、雨滴を検知することにより、直ぐに洗濯物を取り込むようにすることが可能である。   In the invention of claim 2, the wireless tag is installed in a clothes-drying basket or other clothes-drying tool such as a heel that is deployed radially, and the laundry is taken in immediately by detecting raindrops. It is possible.

以下に、本発明の構成を図面に示す発明の実施の形態に基づいて説明すると次の通りである。図1及び図2は本発明の第1の実施の形態に係るものであり、図1の図(A)は物干し竿1の部分断面図、同図の図(B)は無線タグ6の電気回路構成を示す図面、図2は雨検知装置2の全体を示す斜視図である。同図に示す如く、この実施の形態の雨検知装置2は、無線電波を受信するアンテナ3と、無線電波を受信して電源の供給を受け、この電源を利用してデータをアンテナ3から送信する無線タグIC4と、当該無線タグIC4のデータの送信をON/OFF制御するスイッチ5とからなる一つの無線タグ6を有している。そして、これらのアンテナ3と、無線タグIC4と、スイッチ5とは、物干し竿1の内部に埋め込まれており、前記スイッチ5を構成する二つの電極5A,5Bの先端側一部が外部(雨滴を感知する環境の場所)へ露呈している。   The configuration of the present invention will be described below based on the embodiment of the invention shown in the drawings. 1 and 2 relate to a first embodiment of the present invention. FIG. 1A is a partial cross-sectional view of a clothes-drying basket 1, and FIG. 1B is an electric diagram of a wireless tag 6. FIG. Drawing which shows a circuit structure and FIG. 2 are perspective views which show the rain detection apparatus 2 whole. As shown in the figure, a rain detection device 2 according to this embodiment includes an antenna 3 that receives radio waves and a radio wave that is supplied with power and uses this power to transmit data from the antenna 3. The wireless tag IC 4 includes a single wireless tag 6 including a wireless tag IC 4 and a switch 5 that performs ON / OFF control of data transmission of the wireless tag IC 4. These antenna 3, RFID tag IC 4, and switch 5 are embedded in the laundry basket 1, and a part of the tip side of the two electrodes 5 A and 5 B constituting the switch 5 is external (raindrops). It is exposed to the place where the environment is perceived.

一方、図2に示すように、物干し竿1を支える支柱7には、リーダ回路8と雨通知装置9とが内臓されており、リーダ側のアンテナ10は物干し竿1を支持するようにループ状に形成されている。   On the other hand, as shown in FIG. 2, a support circuit 7 that supports the hanging basket 1 includes a reader circuit 8 and a rain notification device 9, and an antenna 10 on the reader side is looped so as to support the hanging basket 1. Is formed.

次に、このように構成された雨検知装置2の動作態様を説明する。今、物干し竿1に洗濯物を干した状態で雨が降って来たと仮定する。雨滴が物干し竿1の外部へ露呈する二つの電極5A,5B間に付着すると、両電極間が短絡する。これによりリーダ側のアンテナ10から送信される無線電波を、無線タグIC4のアンテナ3が受信し、無線タグIC4内部の電圧回路に動作用の電圧を発生させる。   Next, the operation | movement aspect of the rain detection apparatus 2 comprised in this way is demonstrated. Assume that it is now raining with the laundry hanging on the clothesline 1. When raindrops adhere between the two electrodes 5A and 5B exposed to the outside of the clothes basket 1, the two electrodes are short-circuited. As a result, the radio wave transmitted from the antenna 10 on the reader side is received by the antenna 3 of the radio tag IC 4 and generates a voltage for operation in the voltage circuit inside the radio tag IC 4.

またスイッチ5がONになったことにより、無線タグIC4に記憶されているデータが無線通信インターフエイスを通じてアンテナ3からアンテナ10を経てリーダ回路8へ送信される。リーダ回路8は、送信されたデータに応じた設定動作を行い、雨通知装置9に雨が降って来たことを通知させる。この通知は、音や光、電波であってもよい。従って、前記通知を受けた者は、雨が降ってきたことを知ることができ、洗濯物を濡れさせずに雨が降ってきた直後に取り込むことができる。   When the switch 5 is turned ON, data stored in the wireless tag IC 4 is transmitted from the antenna 3 to the reader circuit 8 through the antenna 10 through the wireless communication interface. The reader circuit 8 performs a setting operation according to the transmitted data, and causes the rain notification device 9 to notify that rain has come. This notification may be sound, light, or radio waves. Therefore, the person who has received the notification can know that it has rained, and can take it in immediately after it rains without getting the laundry wet.

このように本実施の形態では、物干し竿1側に設けた雨滴検知センサ部と、リーダ側とは、無線インターフエイスを通じて電源の供給を受け、また雨滴を検知した旨の信号のやりとりを行うことができる。そのため、前記センサ部に電源を供給するための配線及びセンサ部の信号を出力するための配線が不要である。   As described above, in this embodiment, the raindrop detection sensor unit provided on the clothesline 1 side and the reader side receive power supply through the wireless interface and exchange signals indicating that the raindrop has been detected. Can do. For this reason, wiring for supplying power to the sensor unit and wiring for outputting a signal of the sensor unit are unnecessary.

This is intended to detect raindrops in many areas. In the figures (A) and (B), two pairs of strip electrodes are provided in series, and in the figure (C), four pairs of strip electrodes are provided in two rows. Is.
