ところで、前記地震計のうち、長周期地震を感知する地震計は、長周期の小さい加速度の振動を感知する装置であるため、保守点検時に外部から長周期地震と同等の長周期の小さい加速度の試験信号を与えて試験を行うことは困難である。   By the way, among the seismometers, seismometers that detect long-period earthquakes are devices that detect vibrations with long-period small accelerations. It is difficult to perform a test by giving a test signal.

本発明は、このような問題点に鑑みてなされたもので、長周期の小さい加速度の振動を感知する装置を備えた地震検出装置の故障を簡易に診断することのできるエレベータ装置を提供するものである。   The present invention has been made in view of such problems, and provides an elevator apparatus capable of easily diagnosing a failure of an earthquake detection apparatus provided with an apparatus that senses vibrations of acceleration with a small long cycle. It is.

本発明は上記課題を解決するため、次のような手段を採用した。   In order to solve the above problems, the present invention employs the following means.

長周期地震を検出する地震検出装置、および該地震検出装置の検出結果をもとにエレベータの運行を制御する制御装置を備えたエレベータ装置において、前記地震検出装置は、試験入力端子を有し長周期地震を検出する加速度センサ、前記加速度センサの試験入力端子に試験入力を供給する押しボタンスイッチ、および前記押しボタンスイッチが押下されたとき前記加速度センサが出力する擬似的な加速度検出信号を診断し、該診断結果を表示灯の点灯または消灯により表示する制御装置を備えた。   In an elevator apparatus equipped with an earthquake detection apparatus for detecting a long-period earthquake and a control apparatus for controlling the operation of the elevator based on the detection result of the earthquake detection apparatus, the earthquake detection apparatus has a test input terminal and is long. An acceleration sensor for detecting periodic earthquakes, a push button switch for supplying a test input to a test input terminal of the acceleration sensor, and a pseudo acceleration detection signal output by the acceleration sensor when the push button switch is depressed And a control device for displaying the diagnosis result by turning on or off the indicator lamp.

本発明は、以上の構成を備えるため、地震検出装置の故障を簡易に診断することができる。   Since this invention is provided with the above structure, it can diagnose easily the failure of an earthquake detection apparatus.

以下、本発明の実施形態を添付図面を参照しながら説明する。図１は、本実施形態にかかるエレベータ装置を説明する図である。   Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram illustrating an elevator apparatus according to the present embodiment.

図１において、１は長周期地震を検出する地震検出装置、２は加速度センサ４を診断する際に操作する押しボタンスイッチ、３は地震検出装置１全体を制御する制御装置（マイコン）であり、前記擬似加速度検出信号を受信し、受信した擬似加速度検出信号に演算処理を施して加速度センサ４の状態を診断する。４は長周期振動を検出する加速度センサであり、制御装置３から診断指令を受けたとき、擬似的な加速度検出信号（擬似加速度検出信号）を発生する。   In FIG. 1, 1 is an earthquake detection device that detects long-period earthquakes, 2 is a push button switch that is operated when diagnosing the acceleration sensor 4, and 3 is a control device (microcomputer) that controls the entire earthquake detection device 1, The pseudo acceleration detection signal is received, and arithmetic processing is performed on the received pseudo acceleration detection signal to diagnose the state of the acceleration sensor 4. Reference numeral 4 denotes an acceleration sensor that detects long-period vibration, and generates a pseudo acceleration detection signal (pseudo acceleration detection signal) when receiving a diagnosis command from the control device 3.

５は入出力回路であり、制御装置３の診断結果を外部システム７との間で送受信する。また、この入出力回路５の動作状態をもとに地震検出装置１の故障を検出することができる。６は表示部であり、制御装置３の診断結果を表示灯の状態等により表示する。７は入出力回路と接続する外部システムである
図２は、地震検出装置１の外観を説明する図である。図２に示すように地震検出装置１は筐体９内に収納され、前記筐体９の保守員が作業を行う部分には開閉自在のカバー８が取り付けてある。地震検出装置の保守点検に際しては、地震検出装置１本体を収納する筐体を開くことなく、前記カバー部分を開くだけで、保守点検の作業を行うことができる。 また、前記カバーを透明のカバーにすることで、地震検出装置の状態を前記カバーを開くことなく、表示灯の状態で確認することができ、一目で装置が正常であるか異常であるかを判断することができる。また、透明カバーを使用することで、カバーを開閉する必要はないので、塵や埃が装置内に入ることは抑制される。 Reference numeral 5 denotes an input / output circuit that transmits and receives the diagnosis result of the control device 3 to and from the external system 7. Further, a failure of the earthquake detection device 1 can be detected based on the operation state of the input / output circuit 5. Reference numeral 6 denotes a display unit that displays the diagnosis result of the control device 3 according to the state of the indicator lamp or the like. 7 is an external system connected to the input / output circuit. FIG. 2 is a diagram for explaining the external appearance of the earthquake detection apparatus 1. As shown in FIG. 2, the earthquake detection device 1 is housed in a housing 9, and an openable / closable cover 8 is attached to a portion of the housing 9 where a maintenance person works. At the time of maintenance and inspection of the earthquake detection device, maintenance and inspection can be performed simply by opening the cover portion without opening the housing that houses the main body of the earthquake detection device 1. Also, by making the cover a transparent cover, the state of the earthquake detection device can be confirmed in the state of the indicator light without opening the cover, and whether the device is normal or abnormal at a glance. Judgment can be made. Moreover, since it is not necessary to open and close a cover by using a transparent cover, it is suppressed that dust and dust enter into an apparatus.

図３は、地震検出装置の自己診断処理を説明する図である。まず、ステップ１において、保守員は保守点検を行うため押しボタンスイッチ部の透明カバーを開き、ステップ２において、押しボタンスイッチ部の押しボタンスイッチを押下する。ステップ３において、制御装置（マイコン）３は、押しボタンスイッチの押下に応答して、加速度センサ４に対して擬似信号を出力させるための指令信号を出力する。   FIG. 3 is a diagram for explaining self-diagnosis processing of the earthquake detection apparatus. First, in step 1, the maintenance staff opens the transparent cover of the push button switch unit for maintenance inspection, and in step 2, presses the push button switch of the push button switch unit. In step 3, the control device (microcomputer) 3 outputs a command signal for causing the acceleration sensor 4 to output a pseudo signal in response to pressing of the push button switch.

ステップ４において、制御装置より指令を受けた加速度センサ４は、擬似加速度信号を制御装置３に出力する。制御装置３は前記擬似加速度信号の有無を監視し、擬似加速度信号が検出できたときステップ５に進み、検出できないときステップ８に進む。ステップＳ８において、ステップ７と異なる表示灯の状態に駆動する。すなわち、この状態は加速度センサから擬似加速度信号が発生していない状態であるので、装置の異常を表示する。   In step 4, the acceleration sensor 4 that has received a command from the control device outputs a pseudo acceleration signal to the control device 3. The control device 3 monitors the presence or absence of the pseudo acceleration signal. If the pseudo acceleration signal can be detected, the control device 3 proceeds to step 5; In step S8, the display lamp is driven to a state different from that in step 7. That is, since this state is a state in which no pseudo acceleration signal is generated from the acceleration sensor, an abnormality of the apparatus is displayed.

ステップ５において、検出した擬似加速度信号に対して、制御装置３により演算を施し、長周期地震を検出したときに検出する信号と同等の信号を検出する。検出した信号は、外部システム７と接続する入出力回路５へ出力する。   In step 5, the control device 3 performs an operation on the detected pseudo acceleration signal, and detects a signal equivalent to a signal detected when a long-period earthquake is detected. The detected signal is output to the input / output circuit 5 connected to the external system 7.

ステップ６において、ステップ５にて出力した信号により、入出力回路５が正常に動作しているか否かを確認する。   In step 6, it is confirmed from the signal output in step 5 whether the input / output circuit 5 is operating normally.

ステップ６において入出力回路５が正常に動作していると判断した場合には、ステップＳ７において特定の表示灯の状態にする。なお、ステップ６において入出力回路５が正常に動作していないと判断した場合には、ステップ７と異なる表示灯の状態に駆動する。   If it is determined in step 6 that the input / output circuit 5 is operating normally, a specific indicator lamp is set in step S7. When it is determined in step 6 that the input / output circuit 5 is not operating normally, the display lamp is driven to a state different from that in step 7.

このようにして表示灯の状態によって、長周期地震を検出する地震検出装置が故障しているか否かを判断することができる。   In this way, it is possible to determine whether or not the earthquake detection device that detects a long-period earthquake has failed according to the state of the indicator lamp.
