Description

本発明は、主制御装置側と乗りかご側との間で信号の伝送を行なうエレベータの信号伝送装置に関する。   The present invention relates to an elevator signal transmission device that transmits signals between a main control device side and a car side.

従来、エレベータの信号伝送装置においては、テールコードを介してエレベータ制御装置あるいは群管理制御装置と乗りかご間で信号伝送を行なう方法が主流であった。   Conventionally, in an elevator signal transmission device, a method of performing signal transmission between an elevator control device or a group management control device and a car via a tail cord has been the mainstream.

しかしながら近年は建築物の高層化や情報伝送量の増加に伴いテールコードの重量が増加し、また、エレベータ高速化に伴うテールコードの挙動によってエレベータの乗り心地に悪影響を及ぼすようになってきたため、無線による信号伝送装置の開発が進められている。   In recent years, however, the weight of tail cords has increased with the increase in the number of buildings and the amount of information transmitted, and the behavior of the tail cords accompanying the increase in the speed of elevators has adversely affected the riding comfort of elevators. Wireless signal transmission devices are being developed.

このような信号伝送装置としては、エレベータホールの乗りかご呼び登録釦や現在階床案内表示やサービス階案内表示を制御する無線端末装置を設け、信号を無線端末経由で中継して、目的とする端末や制御装置に伝送する方式がある（例えば特許文献１及び特許文献２参照）。   As such a signal transmission device, an elevator hall car call registration button, a wireless terminal device for controlling the current floor guidance display and the service floor guidance display are provided, and the signal is relayed via the wireless terminal for the purpose. There is a method of transmitting to a terminal or a control device (see, for example, Patent Document 1 and Patent Document 2).

また、漏洩同軸ケーブルを用いてエレベータ制御装置と乗りかごの制御信号を無線送受信する方法（例えば特許文献３参照）が提案されている。
特開２００１−１５１４２９号公報 特開２００２−３４８０６１号公報 特開平２−６６０８６号公報 In addition, a method of wirelessly transmitting and receiving control signals for an elevator control device and a car using a leaky coaxial cable has been proposed (see, for example, Patent Document 3).
JP 2001-151429 A JP 2002-348061 A JP-A-2-66086

このような手法では一般に開発コストおよび運用コストを抑えるために無線免許が不要な周波数帯で信号の無線伝送を行なっている。しかし、この手法では同一周波数帯による信号の無線伝送を行なっている他の機器からの電波干渉を受ける場合がある。この場合には伝送エラーが頻発し、データ再送処理等が必要になるため、近年の乗りかご内へのインフォメーションシステムや、監視カメラなどを用いたセキュリティシステムなどのエレベータ付加価値製品に対して十分な実効データ伝送速度を確保できなかった。   In such a technique, in order to suppress development costs and operation costs, radio transmission of signals is generally performed in a frequency band that does not require a radio license. However, with this method, radio interference from other devices that perform radio transmission of signals in the same frequency band may occur. In this case, transmission errors frequently occur and data retransmission processing is required, which is sufficient for elevator value-added products such as information systems in recent cars and security systems using surveillance cameras. The effective data transmission speed could not be secured

そこで、本発明の目的は、主制御装置側と乗りかご側との間で信号の安定した無線伝送を行なうことが可能になるエレベータの信号伝送装置を提供することにある。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an elevator signal transmission device capable of performing stable radio transmission of signals between a main control device side and a car side.

すなわち、本発明に係わるエレベータの信号伝送装置は、主制御装置からの信号を当該主制御装置による走行制御対象の乗りかご側の制御装置に向けて無線伝送する伝送手段に接続する第１の漏洩同軸ケーブルと、乗りかご側の制御装置からの信号を主制御装置に向けて無線伝送する伝送手段に接続する第２の漏洩同軸ケーブルとを備え、第１の漏洩同軸ケーブルと第２の漏洩同軸ケーブルを並行して配置し、各々のスロットからの無線電波の送受信方向を対向させ、各々の漏洩同軸ケーブルが受信する電波の強度が予め定められた条件を満たすように各漏洩同軸ケーブルの間で間隔を設けて据付け固定することを特徴とする。   That is, the elevator signal transmission device according to the present invention is connected to a transmission means for wirelessly transmitting a signal from the main control device to a control device on the car side that is a subject of traveling control by the main control device. A first leaky coaxial cable and a second leaky coaxial cable, comprising: a coaxial cable; and a second leaky coaxial cable connected to a transmission means for wirelessly transmitting a signal from the car-side control device toward the main control device. Place the cables in parallel, make the radio wave transmission / reception directions from each slot face each other, and make sure that the intensity of the radio waves received by each leaky coaxial cable satisfies a predetermined condition. It is characterized in that it is installed and fixed at intervals.

本発明に係わるエレベータの信号伝送装置では、第１の漏洩同軸ケーブルと第２の漏洩同軸ケーブルを並行して配置し、各々のスロットからの無線電波の送受信方向を対向させて無線伝送するので、十分な電界強度が得られると共に電界強度の変動を抑制できるため、主制御装置側と乗りかご側との間で信号の安定した無線伝送を行なうことができる。   In the elevator signal transmission device according to the present invention, the first leaky coaxial cable and the second leaky coaxial cable are arranged in parallel, and radio transmission and reception directions of radio waves from each slot are opposed to each other, Since sufficient electric field strength can be obtained and fluctuations in electric field strength can be suppressed, stable radio transmission of signals can be performed between the main controller side and the car side.

以下図面により本発明の実施形態について説明する。
図１は、本発明の実施形態にしたがったエレベータの構成例を示す鳥瞰図である。

FIG. 1 is a bird's-eye view showing a configuration example of an elevator according to an embodiment of the present invention.
In an elevator according to an embodiment of the present invention, a car 5 is connected to a counterweight 4 via a main rope 3 wound around a sheave 2 provided on a motor shaft of a hoisting machine (not shown).

また、機械室１３にエレベータ制御装置（主制御装置）１が設置される。エレベータ制御装置１は機械室１３に限らず例えば昇降路１４内や図示しないエレベータホールドアの戸袋部に設置してもよい。乗りかご５は乗りかご制御装置１７を備える。乗りかご制御装置１７は当該乗りかご５に搭載される図示しないドアの開閉を制御するドア制御装置、図示しない荷重センサ、ドアの開閉状態を検出するセンサ、着床レベルを検出するセンサ、図示しない各種インジケータおよび図示しない行先階指定釦などと接続される。   An elevator control device (main control device) 1 is installed in the machine room 13. The elevator control device 1 is not limited to the machine room 13 and may be installed, for example, in the hoistway 14 or in a door pocket portion of an elevator holder (not shown). The car 5 includes a car control device 17. The car control device 17 is a door control device that controls the opening and closing of a door (not shown) mounted on the car 5, a load sensor (not shown), a sensor that detects the door open / closed state, a sensor that detects the landing level, a sensor that is not shown. It is connected to various indicators and a destination floor designation button (not shown).

機械室１３には無線ＬＡＮ機器や無線モデムからなる無線データ伝送装置９ａが設けられる。無線データ伝送装置９ａはエレベータ制御装置１と接続される。同様に、乗りかご５には無線ＬＡＮ機器や無線モデムからなる無線データ伝送装置９ｂが設けられる。無線データ伝送装置９ｂは乗りかご制御装置１７と接続される。   The machine room 13 is provided with a wireless data transmission device 9a including a wireless LAN device and a wireless modem. The wireless data transmission device 9a is connected to the elevator control device 1. Similarly, the car 5 is provided with a wireless data transmission device 9b including a wireless LAN device and a wireless modem. The wireless data transmission device 9b is connected to the car control device 17.

無線データ伝送装置９ａには給電線１２ａを介して第１の漏洩同軸ケーブル１０ａが接続される。第１の漏洩同軸ケーブル１０ａの先端には終端抵抗１１ａが取り付けられる。無線データ伝送装置９ｂには給電線１２ｂを介して第２の漏洩同軸ケーブル１０ｂが接続される。第２の漏洩同軸ケーブル１０ｂの先端には終端抵抗１１ｂが取り付けられる。第２の漏洩同軸ケーブル１０ｂはこのケーブルの設置箇所の調整機構１５を介して乗りかご５に取り付けられる。この調整機構１５については後述する。   A first leaky coaxial cable 10a is connected to the wireless data transmission device 9a via a feeder line 12a. A terminating resistor 11a is attached to the tip of the first leaky coaxial cable 10a. A second leaky coaxial cable 10b is connected to the wireless data transmission device 9b via a feeder line 12b. A terminating resistor 11b is attached to the tip of the second leaky coaxial cable 10b. The second leaky coaxial cable 10b is attached to the car 5 via the adjusting mechanism 15 at the installation location of this cable. The adjustment mechanism 15 will be described later.

このように構成されたエレベータにおいて、エレベータ制御装置１は図示しない乗場呼び釦や行先階指定釦あるいは図示しないセキュリティ装置と連携して生成される呼び登録にしたがって巻き上げ機を駆動してシーブ２を回転させ、つり合いおもり４とともに互いに上下反対方向に昇降して乗りかご５を所定の階床に着床制御する。   In the elevator configured as described above, the elevator control device 1 rotates the sheave 2 by driving the hoist according to call registration generated in cooperation with a hall call button, a destination floor designation button (not shown) or a security device (not shown). Then, together with the counterweight 4, the elevator car 5 is moved up and down in opposite directions to control the landing of the car 5 on a predetermined floor.

無線データ伝送装置９ａはエレベータ制御装置１から乗りかご５への出力対象となる信号を変調して、この信号を第１の漏洩同軸ケーブル１０ａから無線データ伝送装置９ｂに送信する。無線データ伝送装置９ｂは無線データ伝送装置９ａから送信された信号を第２の漏洩同軸ケーブル１０ｂにより受信して、これを復調した上で乗りかご制御装置１７に出力する。   The wireless data transmission device 9a modulates a signal to be output from the elevator control device 1 to the car 5, and transmits this signal from the first leaky coaxial cable 10a to the wireless data transmission device 9b. The wireless data transmission device 9b receives the signal transmitted from the wireless data transmission device 9a through the second leaky coaxial cable 10b, demodulates it, and outputs it to the car control device 17.

同様に、無線データ伝送装置９ｂは乗りかご５からエレベータ制御装置１への出力対象となる信号を変調して、この信号を第２の漏洩同軸ケーブル１０ｂから無線データ伝送装置９ａに送信する。無線データ伝送装置９ａは無線データ伝送装置９ｂから送信された信号を第１の漏洩同軸ケーブル１０ａにより受信して、これを復調した上でエレベータ制御装置１に出力する。   Similarly, the wireless data transmission device 9b modulates a signal to be output from the car 5 to the elevator control device 1, and transmits this signal from the second leaky coaxial cable 10b to the wireless data transmission device 9a. The wireless data transmission device 9a receives the signal transmitted from the wireless data transmission device 9b through the first leaky coaxial cable 10a, demodulates it, and outputs it to the elevator control device 1.

図２は、本発明の実施形態にしたがったエレベータの昇降路１４側に取り付けた第１の漏洩同軸ケーブル１０ａおよび乗りかご５に取り付けた第２の漏洩同軸ケーブル１０ｂの位置関係を示す図である。   FIG. 2 is a diagram showing the positional relationship between the first leaky coaxial cable 10a attached to the elevator hoistway 14 side and the second leaky coaxial cable 10b attached to the car 5 according to the embodiment of the present invention. .

本発明の実施形態にしたがったエレベータでは第１の漏洩同軸ケーブル１０ａに漏洩同軸ケーブル被覆３３ａが設けられる。漏洩同軸ケーブル被覆３３ａの中の外部導体にはスロット３１ａ〜３１ｈと呼ばれる多数の孔が設けられる。同様に第２の漏洩同軸ケーブル１０ｂには漏洩同軸ケーブル被覆３３ｂが設けられる。漏洩同軸ケーブル被覆３３ｂの中の外部導体にはスロット３２ａ〜３２ｆと呼ばれる多数の孔が設けられる。   In the elevator according to the embodiment of the present invention, the first leaky coaxial cable 10a is provided with the leaky coaxial cable covering 33a. The outer conductor in the leaky coaxial cable sheath 33a is provided with a number of holes called slots 31a to 31h. Similarly, the leaky coaxial cable coating 33b is provided on the second leaky coaxial cable 10b. The outer conductor in the leaky coaxial cable coating 33b is provided with a number of holes called slots 32a to 32f.

第１の漏洩同軸ケーブル１０ａ内の隣接する複数のスロット３１ａ〜３１ｈが相互に作用して送受信アンテナとして機能する。同様に第２の漏洩同軸ケーブル１０ｂ内の隣接する複数のスロット３２ａ〜３２ｆが相互に作用して送受信アンテナとして機能する。   A plurality of adjacent slots 31a to 31h in the first leaky coaxial cable 10a interact with each other to function as a transmission / reception antenna. Similarly, a plurality of adjacent slots 32a to 32f in the second leaky coaxial cable 10b interact with each other to function as a transmission / reception antenna.

スロット３１ａ〜３１ｈ及びスロット３２ａ〜３２ｆで送受信する主たる電波は指向性を有する。エレベータシステムで用いる無線データ伝送装置９ａ，９ｂでは電波をできるだけ効率よく必要な範囲内でのみ送受信できることが望ましい。   Main radio waves transmitted and received in the slots 31a to 31h and the slots 32a to 32f have directivity. It is desirable that the radio data transmission devices 9a and 9b used in the elevator system can transmit and receive radio waves as efficiently as possible within a necessary range.

そこで、本発明の実施形態では第１の漏洩同軸ケーブル１０ａと第２の漏洩同軸ケーブル１０ｂを並行して配置し、第１の漏洩同軸ケーブル１０ａのスロットからの主たる漏洩電波の方向２１が第２の漏洩同軸ケーブル１０ｂのスロットからの主たるの漏洩電波の方向２２と対向するように第１の漏洩同軸ケーブル１０ａ及び第２の漏洩同軸ケーブル１０ｂの間に間隔を設けて乗りかご５および昇降路１４内および乗りかご５にそれぞれ据付け固定する。   Therefore, in the embodiment of the present invention, the first leaky coaxial cable 10a and the second leaky coaxial cable 10b are arranged in parallel, and the direction 21 of the main leaked radio wave from the slot of the first leaky coaxial cable 10a is the second. The car 5 and the hoistway 14 are provided with a space between the first leaky coaxial cable 10a and the second leaky coaxial cable 10b so as to face the direction 22 of the main leaked radio wave from the slot of the leaky coaxial cable 10b. Install and fix to the inside and the car 5 respectively.

ただし、前述した漏洩電波の方向２１は第１の漏洩同軸ケーブル１０ａの方向に対して斜めの方向であり、漏洩電波の方向２２は第２の漏洩同軸ケーブル１０ｂの方向に対して斜めの方向である。   However, the direction 21 of the leaked radio wave described above is an oblique direction with respect to the direction of the first leaky coaxial cable 10a, and the direction 22 of the leaked radio wave is an oblique direction with respect to the direction of the second leaky coaxial cable 10b. is there.

ここでは、漏洩電波の方向２１，２２が対向するように第１の漏洩同軸ケーブル１０ａ内を伝わる送信電力の進行方向と第２の漏洩同軸ケーブル１０ｂ内を伝わる送信電力の進行方向とが反対になるようにしている。具体的には、昇降路１４内に取り付けた第１の漏洩同軸ケーブル１０ａの上端部に無線伝送手段９ａを接続し、乗りかご５に取り付けた第２の漏洩同軸ケーブル１０ｂの下端部に無線伝送手段９ｂを接続する。つまり終端抵抗１１ａは第１の漏洩同軸ケーブル１０ａの下端部に取り付けられ、終端抵抗１１ｂは第２の漏洩同軸ケーブル１０ｂの上端部に取り付けられる。   Here, the traveling direction of the transmission power transmitted in the first leaky coaxial cable 10a and the traveling direction of the transmission power transmitted in the second leaky coaxial cable 10b are opposite so that the leaked radio wave directions 21 and 22 face each other. It is trying to become. Specifically, the wireless transmission means 9a is connected to the upper end of the first leaky coaxial cable 10a attached in the hoistway 14, and wirelessly transmitted to the lower end of the second leaky coaxial cable 10b attached to the car 5. Connect the means 9b. That is, the termination resistor 11a is attached to the lower end portion of the first leaky coaxial cable 10a, and the termination resistor 11b is attached to the upper end portion of the second leaky coaxial cable 10b.

また、第１の漏洩同軸ケーブル１０ａと第２の漏洩同軸ケーブル１０ｂの漏洩電波の送受信角度がケーブルに対して垂直の角度である場合、第１の漏洩同軸ケーブル１０ａに対して第２の漏洩同軸ケーブル１０ｂの上下を逆にして、第１の漏洩同軸ケーブル１０ａと第２の漏洩同軸ケーブル１０ｂを並行して配置し、各々のスロットからの主たる漏洩電波の方向を対向させてこれら漏洩同軸ケーブルの据付け位置を定めても良いし、第１の漏洩同軸ケーブル１０ａの終端に設けられる終端抵抗１１ａの取り付け方向に対して第２の漏洩同軸ケーブル１０ｂの終端方向を上下逆にして終端抵抗１１ｂを取り付けて該第１及び第２の漏洩同軸ケーブルの据付け位置を定めても良い。   When the transmission / reception angle of the leaked radio waves of the first leaky coaxial cable 10a and the second leaky coaxial cable 10b is an angle perpendicular to the cable, the second leaky coaxial cable with respect to the first leaky coaxial cable 10a. The first leaky coaxial cable 10a and the second leaky coaxial cable 10b are arranged in parallel with the cable 10b turned upside down, and the directions of the main leaked radio waves from the slots are opposed to each other. The installation position may be determined, or the termination resistor 11b is attached with the termination direction of the second leakage coaxial cable 10b upside down with respect to the attachment direction of the termination resistor 11a provided at the termination of the first leakage coaxial cable 10a. Thus, the installation positions of the first and second leaky coaxial cables may be determined.

このような形態とすれば、漏洩同軸ケーブルにより形成された無線伝送路近傍で十分な電界強度が得られると共に、乗りかご５の位置によらず電界強度の変動が抑制されるので、より安定した無線伝送が行なえる。   With such a configuration, a sufficient electric field strength can be obtained in the vicinity of the wireless transmission line formed by the leaky coaxial cable, and fluctuations in the electric field strength are suppressed regardless of the position of the car 5, so that it is more stable. Wireless transmission can be performed.

前述したように、本発明の実施形態にしたがったエレベータでは第２の漏洩同軸ケーブル１０ｂの設置箇所の調整機構１５を備える。図３は、本発明の実施形態にしたがったエレベータの乗りかご５に取り付ける第２の漏洩同軸ケーブル１０ｂの設置箇所の調整機構１５の一例を示す図である。
この調整機構１５はかご側固定具４１、ケーブル固定具４３およびボルトネジ４４でなる。 As described above, the elevator according to the embodiment of the present invention includes the adjusting mechanism 15 for the installation location of the second leaky coaxial cable 10b. FIG. 3 is a diagram showing an example of the adjusting mechanism 15 for the installation location of the second leaky coaxial cable 10b attached to the elevator car 5 according to the embodiment of the present invention.
The adjustment mechanism 15 includes a car-side fixture 41, a cable fixture 43, and a bolt screw 44.

本発明の実施形態にしたがったエレベータでは、乗りかご５の側面にかご側固定具４１が少なくとも２箇所に取り付けられる。かご側固定具４１には長穴４２が設けられる。
また、第２の漏洩同軸ケーブル１０ｂはケーブル固定具４３のリング部分で漏洩同軸ケーブル被覆３３ｂを把持して取り付けられる。ケーブル固定具４３のリング部分には側板が連なる。ケーブル固定具４３の側板にはボルトネジ４４をねじ込むための穴が設けられ、ボルトネジ４４をかご側固定具４１の長穴４２を介してケーブル固定具４３の穴にねじ込む事で第２の漏洩同軸ケーブル１０ｂの位置が固定される。 In the elevator according to the embodiment of the present invention, the car-side fixture 41 is attached to the side surface of the car 5 in at least two places. The car-side fixture 41 is provided with a long hole 42.
The second leaky coaxial cable 10b is attached by gripping the leaky coaxial cable covering 33b at the ring portion of the cable fixture 43. A side plate is connected to the ring portion of the cable fixture 43. The side plate of the cable fixture 43 is provided with a hole for screwing the bolt screw 44, and the second leaky coaxial cable is screwed into the hole of the cable fixture 43 through the elongated hole 42 of the car side fixture 41. The position of 10b is fixed.

このような形態とすれば、かご側固定具４１に設けた長穴４２の前後方向の長さの範囲内（矢印Ａ）でかご側固定具４１とケーブル固定具４３の前後方向の位置関係を調整することができる。つまり第２の漏洩同軸ケーブル１０ｂの設置箇所を調整することができる。これにより、第２の漏洩同軸ケーブル１０ｂと第１の漏洩同軸ケーブル１０ａとの間隔及び漏洩電波の対向角度を調整する事ができ、最良の電界強度が得られるように調整することができる。   With this configuration, the positional relationship between the car-side fixing tool 41 and the cable fixing tool 43 in the front-rear direction is within the range of the length in the front-rear direction of the elongated hole 42 provided in the car-side fixing tool 41 (arrow A). Can be adjusted. That is, the installation location of the second leaky coaxial cable 10b can be adjusted. Thereby, the space | interval of the 2nd leaky coaxial cable 10b and the 1st leaky coaxial cable 10a and the opposing angle of leaked electromagnetic waves can be adjusted, and it can adjust so that the best electric field strength may be obtained.

また、かご側固定具４１をＬ字型とした上で、このかご側固定具４１における長穴９２が設けられた板と連なる側板に別の長穴をさらに設け、乗りかご５にネジ止め用の穴を設け、前述したように第２の漏洩同軸ケーブル１０ｂを取り付けたケーブル固定具４３をかご側固定具４１に固定した状態で、長穴９２が設けられた板と連なる側板の長穴と乗りかご５側の穴に新たなボルトネジをねじ込む事で第２の漏洩同軸ケーブル１０ｂの位置を固定する構成としても良い。このような構成とすれば第２の漏洩同軸ケーブル１０ｂの位置を左右方向にも調整することができる。   In addition, the car-side fixture 41 is L-shaped, and another long hole is further provided in the side plate connected to the plate provided with the long hole 92 in the car-side fixture 41 so that the car 5 can be screwed. In the state where the cable fixture 43 to which the second leaky coaxial cable 10b is attached is fixed to the car-side fixture 41 as described above, the slot on the side plate connected to the plate on which the slot 92 is provided It is good also as a structure which fixes the position of the 2nd leaky coaxial cable 10b by screwing a new volt | bolt screw in the hole by the side of the car 5. FIG. With such a configuration, the position of the second leaky coaxial cable 10b can also be adjusted in the left-right direction.

図４は、本発明の実施形態にしたがったエレベータの昇降路への漏洩同軸ケーブルの取り付け形態の一例を示す図である。
本発明の実施形態にしたがったエレベータでは、昇降路１４内の建屋梁５１などを利用してブラケット（固定部材）５２が取り付けられる。また、レールクリップ５４がガイドレール１０３に取り付けられる。レールクリップ５４はブラケット５２にガイドレール５３を固定するための部材である。レールクリップ５４はガイドレール５３の長辺の一方および他方からそれぞれ突出する。レールクリップ５４にはボルトネジ５５をねじ込むためのねじ穴が設けられる。ねじ穴はブラケット５２にも設けられる。 FIG. 4 is a diagram showing an example of a configuration of a leaky coaxial cable attached to the elevator hoistway according to the embodiment of the present invention.
In the elevator according to the embodiment of the present invention, a bracket (fixing member) 52 is attached using a building beam 51 in the hoistway 14 or the like. A rail clip 54 is attached to the guide rail 103. The rail clip 54 is a member for fixing the guide rail 53 to the bracket 52. The rail clip 54 protrudes from one of the long sides of the guide rail 53 and the other. The rail clip 54 is provided with a screw hole for screwing the bolt screw 55. Screw holes are also provided in the bracket 52.

また、第１の漏洩同軸ケーブル１０ａはケーブル固定具５６のリング部分で漏洩同軸ケーブル被覆３３ａを把持して取り付けられる。ケーブル固定具５６のリング部分に連なる側板にはボルトネジ５５をねじ込むためのねじ穴が設けられる。ボルトネジ５５をブラケット５２のねじ穴、レールクリップ５４のねじ穴およびケーブル固定具５６のねじ穴にねじ込むことでガイドレール５３の位置および第１の漏洩同軸ケーブル１０ａの位置が固定される。
また、ケーブル固定具５６を固定するための新たなねじ穴をブラケット５２に設け、このねじ穴とケーブル固定具５６のねじ穴に別のボルトネジをねじ込むことで第１の漏洩同軸ケーブル１０ａの位置を固定する構成としても良い。 The first leaky coaxial cable 10 a is attached by gripping the leaky coaxial cable covering 33 a at the ring portion of the cable fixture 56.

Further, a new screw hole for fixing the cable fixing tool 56 is provided in the bracket 52, and another bolt screw is screwed into the screw hole and the screw hole of the cable fixing tool 56 to thereby position the first leaky coaxial cable 10a. It is good also as a structure to fix.

このような形態とすれば、昇降路側の第１の漏洩同軸ケーブル１０ａの位置が固定されるので、第１の漏洩同軸ケーブル１０ａと第２の漏洩同軸ケーブル１０ｂとの距離及び電波の対向角度を一定に維持できる。よって、より安定した無線伝送を行なうことができ、第１の漏洩同軸ケーブル１０ａにかかる荷重を低減させることができる。   With this configuration, since the position of the first leaky coaxial cable 10a on the hoistway side is fixed, the distance between the first leaky coaxial cable 10a and the second leaky coaxial cable 10b and the opposing angle of the radio wave are set. Can be kept constant. Therefore, more stable wireless transmission can be performed, and the load applied to the first leaky coaxial cable 10a can be reduced.

また、この形態では、ガイドレール５３を取り付けるためのブラケット５２に対しケーブル固定具５６を介して第１の漏洩同軸ケーブル１０ａを取り付けているので、第１の漏洩同軸ケーブル１０ａを取り付けるために昇降路１４側に新たな固定用部材を設ける必要はなく、経済的に優れている。   In this embodiment, since the first leaky coaxial cable 10a is attached to the bracket 52 for attaching the guide rail 53 via the cable fixture 56, the hoistway is used to attach the first leaky coaxial cable 10a. There is no need to provide a new fixing member on the 14 side, which is economical.
