Description
本発明は、建物に設備されるエレベータの昇降路における各階床間を昇降移動する乗りかごと制御盤との間でかご呼び、インジケータ表示、ドア制御等の各種情報の双方向信号伝送を非接触で行うテールコードレスエレベータ用信号伝送装置に関する。 The present invention provides non-contact bidirectional signal transmission of various information such as car calls, indicator display, door control, etc. between a car and a control panel moving up and down between floors in an elevator hoistway installed in a building The present invention relates to a signal transmission device for a tail cordless elevator performed by
従来、汎用的なエレベータでは、制御盤と乗りかごとの間のかご呼び、インジケータ表示、ドア制御等の各種情報の信号伝送を制御盤から直接テールコードと呼ばれる電線を行っている。ところが、高層な建物に設備されるエレベータでは、テールコードの総延長が長くなってしまうと、これに伴って電圧降下が大きくなってしまうため、テールコードが長くなる場合には相乗的に使用する導体の径(電線の径)を大きくして電圧降下を抑制する必要があるが、こうした場合にはコスト高を回避できなくなってしまう。 Conventionally, in a general-purpose elevator, various information signals such as a car call between a control panel and a car, an indicator display, door control and the like are transmitted directly from the control panel via a cable called a tail cord. However, in an elevator installed in a high-rise building, if the total length of the tail cord becomes longer, the voltage drop increases accordingly, so if the tail cord becomes longer, use it synergistically. Although it is necessary to increase the diameter of the conductor (the diameter of the electric wire) to suppress the voltage drop, in such a case, it becomes impossible to avoid high costs.
また、乗りかごにテールコードを固定する吊り芯が乗りかごの重心に対してずれていると、偏荷重による乗りかごの傾きやテールコードの揺れが乗りかごに伝播し、乗り心地に対して悪影響を与える虞もある。 In addition, if the suspension core that fixes the tail cord to the car is displaced with respect to the center of gravity of the car, the tilt of the car and the swing of the tail cord due to the unbalanced load will propagate to the car, adversely affecting the ride comfort. There is also a risk of giving.
そこで、このような状況を改善するため、制御盤と乗りかごとの間の信号伝送手段として、例えば昇降路の天井やピット等の一端に設けた固定側装置と乗りかごに設けた移動側装置との間で光信号を使用して非接触で光通信を行う光通信システムを構成することにより、テールコードレス仕様としたエレベータが開発されている。このような光通信システムでは、固定側装置と移動側装置との相対位置が乗りかごの移動により変化するため、その相対位置の変化に光通信装置の発光部や受光部が対応できるようにする必要がある。 Therefore, in order to improve such a situation, as a signal transmission means between the control panel and the car, for example, a fixed side device provided at one end of a ceiling or a pit of a hoistway and a moving side device provided in a car An elevator having a tail cordless specification has been developed by configuring an optical communication system that performs optical communication in a non-contact manner using optical signals. In such an optical communication system, since the relative position between the stationary device and the moving device changes due to the movement of the car, the light emitting unit and the light receiving unit of the optical communication device can cope with the change in the relative position. There is a need.
上述したテールコードレスエレベータ用光通信システムに係る周知技術として、テールコードの制限を受けることなく、既設のエレベータに対しても高い自由度で追加装備できる「エレベータの情報伝送システム」(特許文献1参照)が挙げられる。 As a well-known technique related to the optical communication system for tail cordless elevator described above, an “elevator information transmission system” that can be additionally equipped with high degree of freedom to an existing elevator without being restricted by a tail cord (see Patent Document 1). ).
上述した特許文献1記載の技術では、エレベータかごに設置された光受信装置と、昇降路の底部に設置された光送信装置と、光送信装置から送信される光信号の光軸を調整する光軸調整装置と、を備え、光受信装置で光信号を受信するとその受光レベルが光軸調整装置のコントローラへ出力され、光軸調整装置において受光レベルが最大となるようにモータを介して一対の調整歯車を微動制御することにより光送信装置の光軸を適切に調整して光信号の受信確率を向上させることができるものであるが、ここでは光受信装置で受信された受光レベルをフィードバックすることで光送信装置の光軸を調整しているため、移動体(乗りかご)が移動している際の光軸の調整に必要な構成が複雑になってコスト高を回避できないという問題があるばかりでなく、特に高層な建物に設備されるエレベータへの適用を想定すると、昇降路の長さが長い場合には光送信装置及び光受信装置の間における光軸合わせ(光送信装置の光軸調整)が困難になってしまうため、適用し難いという問題がある。 In the technique described in Patent Document 1 described above, an optical receiver installed in an elevator car, an optical transmitter installed at the bottom of a hoistway, and light for adjusting the optical axis of an optical signal transmitted from the optical transmitter. An optical axis adjusting device, and when the optical signal is received by the optical receiving device, the received light level is output to the controller of the optical axis adjusting device, and the optical axis adjusting device uses a pair of motors via the motor to maximize the received light level. By finely controlling the adjustment gear, the optical axis of the optical transmitter can be adjusted appropriately to improve the reception probability of the optical signal. Here, the received light level received by the optical receiver is fed back. As a result, the optical axis of the optical transmitter is adjusted, so that the configuration necessary for adjusting the optical axis when the moving body (car) is moving becomes complicated, and there is a problem that high costs cannot be avoided. If Assuming application to an elevator installed in a particularly high-rise building, if the length of the hoistway is long, the optical axis alignment between the optical transmitter and the optical receiver (the optical axis of the optical transmitter) (Adjustment) becomes difficult, and there is a problem that it is difficult to apply.
本発明は、このような問題点を解決すべくなされたもので、その技術的課題は、簡単な構成で光軸調整が不要であり、乗りかごと制御盤との間における各種情報の双方向信号伝送を非接触で適確に行うことができると共に、昇降路の長い高層な建物への適用が有効なテールコードレスエレベータ用信号伝送装置を提供することにある。 The present invention has been made to solve such problems, and its technical problem is that the optical axis adjustment is not required with a simple configuration, and various types of information are interactively transmitted to and from the car and the control panel.

図3及び図4を参照すれば、昇降路壁部6に設けられる通信機能付ポジテクタ100の凹状部には、通信機能付遮蔽板200の位置を非接触で検出する位置検出手段として働く外側に対向して備えられた位置検出用発光部11、位置検出用受光部12以外に内側に各種情報を光通信により非接触で送受信する第1の通信手段として働く通信用発光部13、通信用受光部14が対向して備えられている。因みに、図1に示した通信機能付ポジテクタ101、102についても同様な構成とされるものである。また、通信機能付遮蔽板200には、通信機能付ポジテクタ100、101、102の凹状部にそれぞれ入り込み、位置検出用発光部11から位置検出用受光部12に対して照射されていた位置検出用の光線束(ビーム)を遮蔽した状態において、第1の通信手段の通信用発光部13、通信用受光部14との間で各種情報を光通信により非接触で送受信する第2の通信手段として働く通信用受光部21、通信用発光部22が備えられている。即ち、係る状態で通信機能付遮蔽板200には、通信用発光部13と対向する一方の主面の位置に通信用受光部21が備えられ、通信用受光部14と対向する他方の主面の位置に通信用発光部22が備えられている。 Referring to FIGS. 3 and 4, the concave portion of the communication function positive detector 100 provided on the hoistway wall portion 6 is provided on the outside serving as a position detection means for detecting the position of the communication function shielding plate 200 in a non-contact manner. In addition to the position-detecting light-emitting unit 11 and the position-detecting light-receiving unit 12 that are provided opposite to each other, a communication light-emitting unit 13 that serves as a first communication means for transmitting and receiving various types of information in a contactless manner by optical communication, and a light-receiving for communication The part 14 is provided facing. Incidentally, the same configuration is applied to the positioners 101 and 102 with communication function shown in FIG. Moreover, the shielding plate 200 with a communication function enters the concave portions of the positive detectors 100, 101, and 102 with a communication function, respectively, and is used for position detection irradiated from the position detection light emitting unit 11 to the position detection light receiving unit 12. As a second communication means for transmitting and receiving various information in a non-contact manner by optical communication between the communication light emitting section 13 and the communication light receiving section 14 of the first communication means in a state where the light beam (beam) of the first communication means is shielded. A working communication light receiving unit 21 and a communication light emitting unit 22 are provided. That is, in this state, the shielding plate with communication function 200 includes the communication light receiving unit 21 at the position of one main surface facing the communication light emitting unit 13 and the other main surface facing the communication light receiving unit 14. The communication light emitting unit 22 is provided at the position.
これらの通信機能付ポジテクタ100の第1の通信手段となる通信用発光部13、通信用受光部14、並びに通信機能付遮蔽板200の第2の通信手段となる通信用発光部22、通信用受光部21は、それぞれ変調された光を用いて各種情報を光通信により非接触で送受信するものである。具体的には、通信機能付ポジテクタ100の第1の通信手段の通信用発光部13、通信用受光部14は、通信機能付遮蔽板200が乗りかご5の昇降移動に伴い、或る行先階の階床で停止して通信機能付ポジテクタ100の凹状部における位置検出手段である位置検出用発光部11、位置検出用受光部12により位置検出される位置で通信機能付遮蔽板200の第2の通信手段の通信用受光部21、通信用発光部22との間で各種情報を光通信により送受信する際、第1の通信手段の通信用発光部13が第2の通信手段の通信用受光部21を通信相手とし、第2の通信手段の通信用発光部22が第1の通信手段の通信用受光部14を通信相手として光通信を行うことになる。 The communication light emitting unit 13 and the communication light receiving unit 14 serving as the first communication unit of the positive detector 100 with the communication function, and the communication light emitting unit 22 serving as the second communication unit of the shielding plate 200 with the communication function and the communication unit. The light receiving unit 21 transmits and receives various information by optical communication in a non-contact manner using each modulated light. Specifically, the communication light-emitting unit 13 and the communication light-receiving unit 14 of the first communication means of the positive detector 100 with a communication function have a certain destination floor as the shielding plate 200 with a communication function moves up and down of the car 5. Of the shielding plate 200 with a communication function at the position detected by the position detection light emitting unit 11 and the position detection light receiving unit 12 which are position detection means in the concave portion of the communication function positive detector 100. When various information is transmitted / received between the communication light receiving unit 21 and the communication light emitting unit 22 of the communication means by optical communication, the communication light emitting unit 13 of the first communication means receives the communication light reception of the second communication means. The communication light-emitting unit 22 of the second communication means performs optical communication with the communication light-receiving unit 14 of the first communication means as the communication partner.
ところで、例えば図1に示される通信機能付ポジテクタ100については、図2中のかご位置表示装置51の呼び登録された行先階に表示されているように昇降路における5階用のものとする場合を例示でき、乗りかご5が5階の階床に停止したときにその凹状部に通信機能付遮蔽板200が入り込む。また、その他の図1に示される通信機能付ポジテクタ101については昇降路における4階用のものとし、同様に通信機能付ポジテクタ102については昇降路における3階用のものとする場合を例示できる。 By the way, for example, the communication function positive detector 100 shown in FIG. 1 is used for the fifth floor in the hoistway as displayed on the call destination registered floor of the car position display device 51 in FIG. When the car 5 stops on the fifth floor, the shielding plate 200 with a communication function enters the concave portion. Further, the other example of the positive detector 101 with communication function shown in FIG. 1 is for the fourth floor in the hoistway, and similarly, the positive detector 102 with communication function is for the third floor in the hoistway.
また、図3を参照すれば、通信機能付ポジテクタ100の第1の通信手段の通信用発光部13には、制御盤31からの乗りかご5のかごドア53の開閉動作やかご位置表示手段51の表示動作を制御するためのシリアル通信形式による制御信号が入力され、これを受けて第2の通信手段の通信用受光部21からは乗りかご5のかごドア53の開閉動作やかご位置表示手段51の表示動作を指示するための動作指示信号が出力される。これに対し、第2の通信手段の通信用発光部22には、乗りかご5内の操作盤52からの目的とする行先階への登録を行う登録操作指示やかごドア53の開閉操作指示を含む操作指示に関するシリアル通信形式による操作指示信号が入力され、これを受けて第1の通信手段の通信用受光部14からは乗りかご5内の機器の操作や装置状態を示す操作・装置状態信号が出力され、係る操作・装置状態信号が制御盤31に入力される。更に、通信機能付ポジテクタ100の位置検出用発光部11には、制御盤31からの位置検出を指示する位置検出指示信号が入力され、これを受けて位置検出用受光部12からは位置検出信号が出力され、係る位置検出信号がポジテクタ出力として制御盤31に入力される。 Referring to FIG. 3, the communication light emitting unit 13 of the first communication means of the positive detector 100 with a communication function includes the opening / closing operation of the car door 53 of the car 5 from the control panel 31 and the car position display means 51. In response to the control signal in the serial communication format for controlling the display operation of the car, the communication light receiving unit 21 of the second communication means receives the opening / closing operation of the car door 53 of the car 5 and the car position display means. An operation instruction signal for instructing the display operation 51 is output. On the other hand, the communication light-emitting unit 22 of the second communication means receives a registration operation instruction for performing registration to the target destination floor and an opening / closing operation instruction for the car door 53 from the operation panel 52 in the car 5. An operation instruction signal in the serial communication format related to the operation instruction including the input is received, and from the communication light receiving unit 14 of the first communication means, an operation / device state signal indicating the operation of the device in the car 5 and the device state is received. Is output, and the operation / device state signal is input to the control panel 31. Further, a position detection instruction signal for instructing position detection from the control panel 31 is input to the position detection light emitting unit 11 of the position detector 100 with communication function, and the position detection signal is received from the position detection light receiving unit 12 in response thereto. The position detection signal is input to the control panel 31 as a positive detector output.
次に、各図を参照し、実施例に係るテールコードレスエレベータ用信号伝送装置における各種情報を含む各種信号の送受信の手順に係る基本動作を説明する。まず、乗りかご5が昇降路における呼び登録のある階床(乗場)でない位置(例えば階床間)にある場合には、通信機能付ポジテクタ100の凹状部に通信機能付遮蔽板200が入り込んでいないため、位置検出用発光部11から照射された光線束が遮蔽されずに位置検出用受光部12に到達し、この状態で通信機能付ポジテクタ100は位置検出信号を出力せず、ポジテクタ出力が無い状態となり、制御盤31に対して乗りかご5が停止位置でない旨の信号を入力する。 Next, with reference to each figure, the basic operation | movement which concerns on the procedure of transmission / reception of the various signals containing the various information in the signal transmission apparatus for tail cordless elevators concerning an Example is demonstrated. First, when the car 5 is in a position (for example, between floors) where the call registration is not performed in the hoistway (for example, between floors), the shielding plate 200 with the communication function enters the concave portion of the positive detector 100 with the communication function. Therefore, the beam bundle irradiated from the position detection light-emitting unit 11 reaches the position detection light-receiving unit 12 without being blocked. In this state, the positive detector 100 with a communication function does not output a position detection signal, and the positive detector output is A signal indicating that the car 5 is not at the stop position is input to the control panel 31.
これに対し、乗りかご5が昇降路における呼び登録のある階床(乗場)の停止位置にある場合には、通信機能付ポジテクタ100の凹状部に通信機能付遮蔽板200が入り込んでいるため、位置検出用発光部11から照射された光線束が遮蔽されて位置検出用受光部12に到達せず、この状態で通信機能付ポジテクタ100は位置検出信号を出力してポジテクタ出力が有る状態となり、制御盤31に対して乗りかご5が停止位置にある旨の信号を入力する。このように、制御盤31がポジテクタ出力の有無を確認し、通信機能付ポジテクタ100の凹状部に通信機能付遮蔽板200が位置されている状況を検出すると、通信用発光部13を制御して通信機能付遮蔽板200の通信用受光部21に向けて乗りかご5のかごドア53の開閉やかご位置表示装置51の表示を動作制御するための制御信号をシリアル通信形式に変換した信号により変調した光線束を照射する。これにより、通信用受光部21は光線束を受光すると、乗りかご5のかごドア53の開閉動作やかご位置表示手段51の表示動作を指示するための動作指示信号を出力するため、かごドア53やかご位置表示手段51を制御盤31で制御できることになる。 On the other hand, when the car 5 is at the stop position of the floor (landing) with call registration in the hoistway, the communication function shielding plate 200 enters the concave portion of the communication function positive detector 100, The beam bundle irradiated from the position detection light emitting unit 11 is shielded and does not reach the position detection light receiving unit 12, and in this state, the positive detector 100 with a communication function outputs a position detection signal and has a positive detector output. A signal indicating that the car 5 is at the stop position is input to the control panel 31. In this way, when the control panel 31 confirms the presence or absence of the output of the positive detector and detects the situation where the shielding plate 200 with the communication function is positioned in the concave portion of the positive detector 100 with the communication function, the control light emitting unit 13 is controlled. A control signal for controlling the opening / closing of the car door 53 of the car 5 and the display of the car position display device 51 toward the communication light receiving unit 21 of the shielding plate with communication function 200 is modulated by a signal converted into a serial communication format. Irradiate the light beam. Thus, when the communication light receiving unit 21 receives the light beam, the car door 53 outputs an operation instruction signal for instructing an opening / closing operation of the car door 53 of the car 5 and a display operation of the car position display means 51. The cage position display means 51 can be controlled by the control panel 31.
更に、乗りかご5内の操作盤52は、行先階への呼び登録等の操作指示に関する情報をシリアル信号に変換し、通信機能付遮蔽板200の通信用発光部22を制御して通信機能付ポジテクタ100の通信用受光部14に向けてシリアル信号に変換した操作指示信号により変調した光線束を照射する。これにより、通信用受光部14は光線束を受光すると、行先階への呼び登録等の操作指示の情報を操作・装置状態信号として制御盤31へ送出するため、操作盤52による行先階への呼び登録等の操作指示に関する情報が制御盤31に伝送されることになる。 Further, the operation panel 52 in the car 5 converts information related to an operation instruction such as call registration to the destination floor into a serial signal, and controls the communication light emitting unit 22 of the shielding plate 200 with a communication function to provide a communication function. The light beam modulated by the operation instruction signal converted into a serial signal is emitted toward the communication light receiving unit 14 of the positive detector 100. As a result, when the communication light receiving unit 14 receives the light beam, it sends information on operation instructions such as call registration to the destination floor to the control panel 31 as an operation / device state signal. Information regarding operation instructions such as call registration is transmitted to the control panel 31.
