Description

短絡検査装置及び短絡検査方法Short-circuit inspection apparatus and short-circuit inspection method
　本発明は、非接触により電力を授受可能な電力伝送システムの短絡検査装置に関し、特に、電力伝送システムが備えるオープン型アンテナの短絡を検査する短絡検査装置及び短絡検査方法の技術分野に関する。 The present invention relates to a short-circuit inspection device for a power transmission system that can exchange power without contact, and more particularly to a technical field of a short-circuit inspection device and a short-circuit inspection method for inspecting a short circuit of an open antenna included in the power transmission system.
　この種の装置が検査対象とするオープン型アンテナとして、例えば、２層構造を有するスパイラルアンテナが提案されている（非特許文献１参照）。ここでは特に、導体の線径、巻き数、ピッチ等によってインダクタンス値を調整可能であることが記載されている。 For example, a spiral antenna having a two-layer structure has been proposed as an open type antenna to be inspected by this type of device (see Non-Patent Document 1). In particular, it is described that the inductance value can be adjusted by the wire diameter, the number of turns, the pitch, and the like of the conductor.
　しかしながら、上述の背景技術では、主に、アンテナを形成する導体の線径、巻き数、ピッチ等による電力伝送特性に対する効果のみに着目しており、該アンテナを実用化する際に問題となるであろう事項については検討されていないという技術的問題点がある。 However, the above-described background art mainly focuses only on the effect on the power transmission characteristics due to the wire diameter, the number of turns, the pitch, and the like of the conductor forming the antenna, which becomes a problem when putting the antenna into practical use. There is a technical problem that there is no study on what would be done.
　本発明は、例えば上記問題点に鑑みてなされたものであり、オープン型アンテナの短絡を適切に検知することができる短絡検査装置及び短絡検査方法を提案することを課題とする。 The present invention has been made in view of the above-mentioned problems, for example, and an object thereof is to propose a short-circuit inspection apparatus and a short-circuit inspection method that can appropriately detect a short circuit of an open antenna.
　本発明の短絡検査装置は、上記課題を解決するために、オープン型のアンテナと、前記アンテナと交流電源又は電気的負荷とを電気的に接続する主回路と、を備える電力伝送装置に搭載され、直流電源と、前記アンテナと前記直流電源とを電気的に接続する副回路と、前記副回路に係る電圧又は電流を検出する検出手段と、前記検出された電圧又は電流に基づいて、前記アンテナが短絡しているか否かを判定する判定手段と、を備える。 In order to solve the above-described problems, a short-circuit inspection apparatus according to the present invention is mounted on a power transmission device including an open antenna and a main circuit that electrically connects the antenna and an AC power supply or an electrical load. A DC circuit, a sub-circuit that electrically connects the antenna and the DC power source, a detection unit that detects a voltage or current associated with the sub-circuit, and the antenna based on the detected voltage or current Determining means for determining whether or not the circuit is short-circuited.
　本発明の短絡検査装置によれば、当該短絡検査装置は、オープン型のアンテナと、該アンテナと交流電源又は電気的負荷（例えば、バッテリ等）とを電気的に接続する主回路と、を備える電力伝送装置に搭載される。 According to the short-circuit inspection apparatus of the present invention, the short-circuit inspection apparatus includes an open-type antenna and a main circuit that electrically connects the antenna to an AC power source or an electrical load (for example, a battery). Installed in power transmission equipment.
　「オープン型のアンテナ」とは、２本の導線（エレメント）を有するアンテナを意味する。該アンテナは、例えばエナメル線等の導体がらせん状に巻かれることにより形成されてもよいし、例えばプリント基板上に導体が所定形状に配置されることにより形成されてもよい。尚、「オープン型のアンテナ」と対をなす概念として、１本の導線から構成されているクローズ型のアンテナがある。 “Open type antenna” means an antenna having two conductors (elements). The antenna may be formed by winding a conductor such as an enameled wire in a spiral shape, or may be formed by arranging a conductor in a predetermined shape on a printed board, for example. A concept that forms a pair with an “open type antenna” is a closed type antenna composed of a single conductor.
　電力伝送装置には、オープン型のアンテナと交流電源とが主回路により電気的に接続された送電側の電力伝送装置と、オープン型のアンテナと電気的負荷とが主回路により電気的に接続された受電側の電力伝送装置と、が存在する。 In the power transmission device, the power transmission device on the power transmission side in which the open type antenna and the AC power source are electrically connected by the main circuit, and the open type antenna and the electrical load are electrically connected by the main circuit. And a power transmission device on the power receiving side.
　送電側の電力伝送装置のオープン型のアンテナと、受電側の電力伝送装置のオープン型のアンテナとが所定の間隔を隔てて対向して配置された後、交流電源から送電側の電力伝送装置のオープン型のアンテナに交流電力が供給されると、例えば磁界共鳴等により非接触で、送電側の電力伝送装置から受電側の電力伝送装置に電力が供給される。 After the open type antenna of the power transmission device on the power transmission side and the open type antenna of the power transmission device on the power reception side are arranged to face each other at a predetermined interval, When AC power is supplied to the open antenna, power is supplied from the power transmission device on the power transmission side to the power transmission device on the power reception side in a non-contact manner, for example, by magnetic resonance.
　短絡検査装置は、直流電源、副回路、検出手段及び判定手段を備えて構成されている。上述の如く、本発明に係る電力伝送装置のアンテナはオープン型であり、該アンテナのグランド線と芯線との間は開放状態となっている。このため、アンテナが正常であれば、該アンテナに直流電源を電気的に接続したとしても、直流電流は流れない。従って、副回路に係る、例えば電圧は、０Ｖとなる。他方で、例えば製造時の不備や、外部からの衝撃等に起因するアンテナの変形、等により、該アンテナを構成する２本のエレメントが電気的に接触すると、アンテナに直流電源を電気的に接続した場合に、副回路に直流電流が流れることとなる。 The short-circuit inspection device includes a DC power supply, a sub circuit, detection means, and determination means. As described above, the antenna of the power transmission device according to the present invention is an open type, and the ground wire and the core wire of the antenna are open. For this reason, if the antenna is normal, no DC current flows even if a DC power supply is electrically connected to the antenna. Therefore, for example, the voltage related to the sub circuit is 0V. On the other hand, when the two elements constituting the antenna come into electrical contact due to, for example, inadequacy during manufacturing or deformation of the antenna due to external impact, etc., a DC power supply is electrically connected to the antenna. In this case, a direct current flows in the sub circuit.
　従って、副回路に係る電圧又は電流を検出すれば、比較的容易にして、オープン型のアンテナが短絡しているか否かを判定することができる。尚、副回路の直流電源ではなく、主回路の交流電源を用いても、反射電力を観察することにより、電力伝送装置に異常があるか否かを判定することはできるが、異常の原因を特定することはできない、ことが本願発明者の研究により判明している。 Therefore, if the voltage or current relating to the sub-circuit is detected, it can be determined relatively easily whether or not the open-type antenna is short-circuited. Even if the AC power supply of the main circuit is used instead of the DC power supply of the sub circuit, it is possible to determine whether or not there is an abnormality in the power transmission device by observing the reflected power. It has been found by the inventor's research that it cannot be specified.
　以上の結果、本発明の短絡検査装置によれば、オープン型のアンテナの短絡を適切に検知することができる。特に、直流電源は、オープン型のアンテナの短絡を検知可能な程度の出力を有していればよいので、短絡検査装置自体の小型化や製造コストの低減を図ることができる。 As a result, according to the short circuit inspection apparatus of the present invention, it is possible to appropriately detect a short circuit of the open type antenna. In particular, since the DC power supply only needs to have an output that can detect a short circuit of the open antenna, it is possible to reduce the size and manufacturing cost of the short circuit inspection device itself.
　本発明の短絡検査装置の一態様では、前記主回路と前記副回路とを相互に切り換え可能な切換手段と、前記アンテナの短絡を検査する際に、前記副回路を選択するように前記切換手段を制御する制御手段と、を更に備える。 In one aspect of the short circuit inspection apparatus of the present invention, the switching means capable of switching between the main circuit and the sub circuit mutually, and the switching means so as to select the sub circuit when inspecting the short circuit of the antenna. And a control means for controlling.
　この態様によれば、比較的容易にして、主回路と、副回路とを切り換えることができ、実用上非常に有利である。 According to this aspect, the main circuit and the sub circuit can be switched relatively easily, which is very advantageous in practice.
　尚、例えばメモリ、プロセッサ等を備えてなる制御手段は、例えば、電力伝送の開始直前に、所定周期で、オープン型のアンテナの短絡が検査されるように、副回路を選択するように切換手段を制御すればよい。 Note that the control means including, for example, a memory, a processor, and the like is, for example, a switching means so as to select a sub-circuit so that a short circuit of the open antenna is inspected at a predetermined cycle immediately before the start of power transmission. Can be controlled.
　或いは、本発明の短絡検査装置の他の態様では、前記主回路は、ＤＣブロッキングコンデンサを含む。 Alternatively, in another aspect of the short circuit inspection apparatus of the present invention, the main circuit includes a DC blocking capacitor.
　この態様によれば、部品点数を低減することができる。加えて、例えば、主回路と副回路とを切り換えるスイッチ素子等の機械的動作部品を用いることなく、電力伝送と短絡検査とを切り換えることができるので、短絡検査装置及び電力伝送装置の故障を抑制することができる。 According to this aspect, the number of parts can be reduced. In addition, for example, it is possible to switch between power transmission and short circuit inspection without using mechanical operation parts such as a switch element that switches between the main circuit and the sub circuit, thereby suppressing the failure of the short circuit inspection device and the power transmission device. can do.
　本発明の短絡検査方法は、上記課題を解決するために、オープン型のアンテナと、前記アンテナと交流電源又は電気的負荷とを電気的に接続する主回路と、を備える電力伝送装置に搭載され、直流電源と、前記アンテナと前記直流電源とを電気的に接続する副回路と、を備える短絡検査装置における短絡検査方法であって、前記副回路に係る電圧又は電流を検出する検出工程と、前記検出された電圧又は電流に基づいて、前記アンテナが短絡しているか否かを判定する判定工程と、を備える。 In order to solve the above problems, a short circuit inspection method of the present invention is mounted on a power transmission device including an open antenna and a main circuit that electrically connects the antenna and an AC power supply or an electrical load. A short circuit inspection method in a short circuit inspection apparatus comprising a direct current power source and a sub circuit electrically connecting the antenna and the direct current power source, and detecting a voltage or current associated with the sub circuit; And a determination step of determining whether or not the antenna is short-circuited based on the detected voltage or current.
　本発明の短絡検査方法によれば、上述した本発明の短絡検査装置と同様に、オープン型のアンテナの短絡を適切に検知することができる。 According to the short circuit inspection method of the present invention, it is possible to appropriately detect a short circuit of the open type antenna as in the case of the short circuit inspection apparatus of the present invention described above.
　尚、本発明の短絡検査方法においても、上述した本発明の短絡検査装置の各種態様と同様の各種態様を採ることができる。 In addition, also in the short circuit inspection method of this invention, the various aspects similar to the various aspects of the short circuit inspection apparatus of this invention mentioned above can be taken.
　本発明の作用及び他の利得は次に説明する実施するための形態から明らかにされる。 The operation and other advantages of the present invention will be clarified from the embodiments to be described below.
