FIG. 2 is a block diagram of the elevator monitoring device and the determination device according to the first embodiment.
　図２に示されるように、監視装置１４は、運転モード設定部１４ａと画像情報取得部１４ｂとを備える。 As shown in FIG. 2, the monitoring device 14 includes an operation mode setting unit 14a and an image information acquisition unit 14b.
　運転モード設定部１４ａは、エレベーターの運転モードを設定する。画像情報取得部１４ｂは、運転モード設定部１４ａがエレベーターの運転モードを防犯カメラ１２の汚れを検知するための画像採取モードに設定したか否かを判定する。 The operation mode setting unit 14a sets the operation mode of the elevator. The image information acquisition unit 14b determines whether the operation mode setting unit 14a has set the operation mode of the elevator to the image collection mode for detecting the dirt on the security camera 12.
　運転モード設定部１４ａがエレベーターの運転モードを遠隔点検時における画像採取モードに設定した場合、画像情報取得部１４ｂは、防犯カメラ１２の汚れを検知するための画像の情報を取得する画像情報取得条件が成立しているか否かを判定する。 When the operation mode setting unit 14a sets the operation mode of the elevator to the image collection mode during remote inspection, the image information acquisition unit 14b acquires the image information acquisition condition for acquiring the information of the image for detecting the dirt on the security camera 12. It is determined whether or not is established.
　例えば、かご６の内部が無人である場合、画像情報取得部１４ｂは、当該画像情報取得条件が成立していると判定する。例えば、かご６の照明装置１０が点灯している際にかご６の内部が無人である場合、画像情報取得部１４ｂは、当該画像情報取得条件が成立していると判定する。例えば、かご６のドアが閉じている際にかご６の照明装置１０が点灯しており、かご６の内部が無人である場合、画像情報取得部１４ｂは、当該画像情報取得条件が成立していると判定する。例えば、かご６が停止している際に、かご６のドアが閉じており、かご６の照明装置１０が点灯しており、かご６の内部が無人である場合、画像情報取得部１４ｂは、当該画像情報取得条件が成立していると判定する。例えば、かご６が予め設定された特定階に停止している際に、かご６のドアが閉じており、かご６の照明装置１０が点灯しており、かご６の内部が無人である場合、画像情報取得部１４ｂは、当該画像情報取得条件が成立していると判定する。 For example, when the inside of the car 6 is unattended, the image information acquisition unit 14b determines that the image information acquisition condition is satisfied. For example, when the inside of the car 6 is unattended when the lighting device 10 of the car 6 is turned on, the image information acquisition unit 14b determines that the image information acquisition condition is satisfied. For example, when the illumination device 10 of the car 6 is turned on when the door of the car 6 is closed and the inside of the car 6 is unattended, the image information acquisition unit 14b determines that the image information acquisition condition is satisfied. Determine that For example, when the car 6 is stopped, the door of the car 6 is closed, the illumination device 10 of the car 6 is turned on, and the inside of the car 6 is unattended, the image information acquisition unit 14b It is determined that the image information acquisition condition is satisfied. For example, when the car 6 is stopped at a preset specific floor, the door of the car 6 is closed, the lighting device 10 of the car 6 is turned on, and the inside of the car 6 is unattended, The image information acquisition unit 14b determines that the image information acquisition condition is satisfied.
　当該画像情報取得条件が成立している場合、画像情報取得部１４ｂは、防犯カメラ１２の画像の情報を取得する。画像情報取得部１４ｂは、当該画像の情報を判定装置１５に送信する。 If the image information acquisition condition is satisfied, the image information acquisition unit 14b acquires information on the image of the security camera 12. The image information acquisition unit 14b transmits information about the image to the determination device 15.
　図２に示されるように、判定装置１５は、判定部１５ａを備える。 As shown in FIG. 2, the determination device 15 includes a determination unit 15a.
　判定部１５ａは、監視装置１４からの画像の情報に基づいて防犯カメラ１２の汚れ具合を判定する。 The determination unit 15a determines the degree of contamination of the security camera 12 based on the image information from the monitoring device 14.
　例えば、判定部１５ａは、防犯カメラ１２が汚れておらずに画像情報取得条件が成立した状態、例えばかご６の内部が無人の場合における防犯カメラ１２の基準画像の情報とエレベーターの運転モードが画像採取モードである際に監視装置１４が取得した画像の情報との比較結果に基づいて、防犯カメラ１２の汚れ具合を判定する。この際、判定部１５ａは、画像の情報を数値化した上で、防犯カメラ１２の汚れ具合を判定する。 For example, the determination unit 15a displays the image of the reference image of the security camera 12 and the operation mode of the elevator when the security camera 12 is not dirty and the image information acquisition condition is satisfied, for example, when the inside of the car 6 is unattended. The degree of contamination of the security camera 12 is determined based on the result of comparison with the information of the image acquired by the monitoring device 14 in the sampling mode. At this time, the determination unit 15a digitizes the information of the image and then determines the degree of contamination of the security camera 12.
　判定部１５ａは、エレベーターの運転モードが画像採取モードである際に監視装置１４がかご６の内部が無人の場合における防犯カメラ１２の画像の情報を取得した際に、当該画像の情報に基づいて、防犯カメラ１２の故障を判定する。例えば、当該画像の情報の大部分が黒色を示す情報である場合、判定部１５ａは、防犯カメラ１２が故障していると判定する。 When the monitoring unit 14 acquires the information of the image of the security camera 12 when the inside of the car 6 is unattended when the elevator operation mode is the image collection mode, the determination unit 15a is based on the information of the image. Then, the failure of the security camera 12 is determined. For example, when most of the information of the image is information indicating black, the determination unit 15a determines that the security camera 12 is out of order.
　次に、図３を用いて、監視装置１４の動作の概要を説明する。
　図３は実施の形態１におけるエレベーターの監視装置の動作の概要を説明するためのフローチャートである。 Next, the outline of the operation of the monitoring device 14 will be described with reference to FIG.
FIG. 3 is a flowchart for explaining the outline of the operation of the elevator monitoring device according to the first embodiment.
　ステップ１では、監視装置１４は、現時刻がエレベーターの運転モードを画像採取モードに設定する時間帯であるか否かを判定する。 In step 1, the monitoring device 14 determines whether or not the current time is a time zone when the elevator operation mode is set to the image acquisition mode.
　ステップＳ１で現時刻がエレベーターの運転モードを画像採取モードに設定する時間帯でない場合、監視装置１４は、ステップＳ１の動作を行う。ステップＳ１で現時刻がエレベーターの運転モードを画像採取モードに設定する時間帯である場合、監視装置１４は、ステップＳ２の動作を行う。 If the current time is not the time zone for setting the elevator operation mode to the image acquisition mode in step S1, the monitoring device 14 performs the operation in step S1. If the current time is the time zone in which the elevator operation mode is set to the image acquisition mode in step S1, the monitoring device 14 performs the operation of step S2.
　ステップＳ２では、監視装置１４は、エレベーターの運転モードを画像採取モードに設定する。画像採取モードの設定において、監視装置１４は、画像情報取得条件の成立を促進するために促進指令を制御装置１３に出力してもよい。例えば、画像採取モードの設定において、上述した画像情報取得条件にかご６の照明装置１０が点灯していることが含まれる場合、監視装置１４は、かご６の照明装置１０が点灯しているか消灯しているかの判定を行う。この判定においてかご６の照明装置１０が消灯していると判定された場合、監視装置１４は、かご６の照明装置１０を点灯させるための促進指令を制御装置１３に出力する。例えば、画像採取モードの設定において、上述した画像情報取得条件にかご６のドアが閉じていることが含まれる場合、監視装置１４は、かご６のドアが閉じているか開いているかの判定を行う。この判定においてかご６のドアが開いていると判定された場合、監視装置１４は、かご６のドアを閉じるための促進指令を制御装置１３に出力する。例えば、画像採取モードの設定において、上述した画像情報取得条件に予め設定された特定階に停止していることが含まれる場合、監視装置１４は、かご６が予め設定された特定階に停止しているか否かの判定を行う。この判定においてかご６が予め設定された特定階に停止していないと判定された場合、監視装置１４はかご６を予め設定された特定階に移動させるための促進指令を制御装置１３に出力する。その後、監視装置１４は、ステップＳ３の動作を行う。ステップＳ３では、監視装置１４は、画像情報取得条件が成立しているか否かを判定する。 In step S2, the monitoring device 14 sets the elevator operation mode to the image acquisition mode. In setting the image acquisition mode, the monitoring device 14 may output a promotion command to the control device 13 in order to promote the establishment of the image information acquisition condition. For example, in the setting of the image acquisition mode, when the above-mentioned image information acquisition condition includes the lighting device 10 of the car 6 being turned on, the monitoring device 14 causes the monitoring device 14 to turn on or off the lighting device 10 of the car 6. Judge whether or not. When it is determined in this determination that the illumination device 10 of the car 6 is off, the monitoring device 14 outputs a promotion command for turning on the illumination device 10 of the car 6 to the control device 13. For example, in the setting of the image acquisition mode, when the above-mentioned image information acquisition condition includes that the door of the car 6 is closed, the monitoring device 14 determines whether the door of the car 6 is closed or open. .. When it is determined in this determination that the door of the car 6 is open, the monitoring device 14 outputs a promotion command for closing the door of the car 6 to the control device 13. For example, in the setting of the image acquisition mode, when the above-mentioned image information acquisition condition includes the fact that the car 6 is stopped at the preset specific floor, the monitoring device 14 stops the car 6 at the preset specific floor. It is determined whether or not When it is determined in this determination that the car 6 has not stopped at the preset specific floor, the monitoring device 14 outputs a promotion command for moving the car 6 to the preset specific floor to the control device 13. .. Then, the monitoring device 14 performs the operation of step S3. In step S3, the monitoring device 14 determines whether or not the image information acquisition condition is satisfied.
　ステップＳ３で画像情報取得条件が成立していない場合、監視装置１４は、ステップＳ１の動作を行う。画像情報取得条件が成立しないままステップ１の画像採取モードに設定する時間帯が経過した場合、一旦画像採取モードの設定動作を中止し、例えば翌日の同時間帯に画像採取モードの設定動作を再開するようにしてもよい。また、ステップＳ３で画像情報取得条件が成立していない場合に、監視装置１４は、上述した画像情報取得条件の成立を促進するために促進指令を制御装置１３に出力するようにしてもよい。ステップＳ３で画像情報取得条件が成立している場合、監視装置１４は、ステップＳ４の動作を行う。 If the image information acquisition condition is not satisfied in step S3, the monitoring device 14 performs the operation of step S1. If the time period for setting the image acquisition mode in step 1 elapses without satisfying the image information acquisition condition, the operation for setting the image acquisition mode is temporarily stopped and, for example, the operation for setting the image acquisition mode is restarted at the same time on the next day. You may do so. Further, when the image information acquisition condition is not satisfied in step S3, the monitoring device 14 may output a promotion command to the control device 13 in order to promote the satisfaction of the above-described image information acquisition condition. If the image information acquisition condition is satisfied in step S3, the monitoring device 14 performs the operation of step S4.
　ステップＳ４では、監視装置１４は、防犯カメラ１２の画像の情報を取得する。その後、監視装置１４は、ステップＳ５の動作を行う。ステップＳ５では、監視装置１４は、当該画像の情報を判定装置１５に送信する。その後、監視装置１４は、動作を終了する。 In step S4, the monitoring device 14 acquires information on the image of the security camera 12. After that, the monitoring device 14 performs the operation of step S5. In step S5, the monitoring device 14 transmits the information of the image to the determination device 15. After that, the monitoring device 14 ends the operation.

In step S15, the determination device 15 transmits information indicating that the security camera 12 is out of order to the information center device 16. Then, the determination device 15 ends the operation.

　ステップＳ２１では、情報センター装置１６は、判定装置１５からの情報が受信されたか否かを判定する。ステップＳ２１で判定装置１５からの情報が受信されていない場合、情報センター装置１６は、ステップＳ２１の動作を行う。ステップＳ２１で判定装置１５からの情報が受信された場合、情報センター装置１６は、ステップＳ２２の動作を行う。 In step S21, the information center device 16 determines whether the information from the determination device 15 has been received.

In step S24, the information center device 16 registers, as the maintenance history of the elevator, information indicating that the security camera 12 is not dirty and has not failed. After that, the information center device 16 ends the operation.
　ステップＳ２２で防犯カメラ１２が故障している場合、情報センター装置１６は、ステップＳ２５の動作を行う。ステップＳ２５では、情報センター装置１６は、防犯カメラ１２が故障していることを示す情報を当該エレベーターの保守履歴として登録する。この際、情報センター装置１６は、当該エレベーターが設けられた建築物付近にいる保守員の携帯端末に防犯カメラ１２が故障していることを示す情報を送信する。その後、情報センター装置１６は、動作を終了する。 If the security camera 12 is out of order in step S22, the information center device 16 operates in step S25.

After that, the information center device 16 ends the operation.
　以上で説明した実施の形態１によれば、エレベーターの運転モードが画像採取モードの際に、かご６の内部が無人である場合における防犯カメラ１２の画像が採取される。このため、プライバシーを確保しつつ、防犯カメラ１２の汚れを検知することができる。なお、かご６の内部が無人であるか否かは、秤装置１１の検出結果に基づいて判定すればよい。また、かご呼びが存在しないときにかご６の内部が無人であると判定してもよい。 According to the first embodiment described above, the image of the security camera 12 when the inside of the car 6 is unmanned is collected when the elevator operation mode is the image collection mode. Therefore, it is possible to detect dirt on the security camera 12 while ensuring privacy. Whether or not the inside of the car 6 is unattended may be determined based on the detection result of the weighing device 11. Alternatively, it may be determined that the inside of the car 6 is unattended when there is no car call.
　例えば、監視装置１４は、照明装置１０が点灯している際に、かご６の内部が無人である場合における防犯カメラ１２の画像の情報を取得する。このため、かご６の内部がより明るい状態のときに防犯カメラ１２の画像の情報を取得することができる。その結果、防犯カメラ１２の汚れをより確実に検知することができる。 For example, the monitoring device 14 acquires the information of the image of the security camera 12 when the inside of the car 6 is unattended when the lighting device 10 is turned on. Therefore, the information of the image of the security camera 12 can be acquired when the inside of the car 6 is in a brighter state. As a result, the dirt on the security camera 12 can be detected more reliably.
　例えば、監視装置１４は、かご６のドアが閉じている際に、照明装置１０が点灯しており、かご６の内部が無人である場合における防犯カメラ１２の画像の情報を取得する。このため、防犯カメラ１２の画像の情報を取得する際の条件を揃えることができ、かつ、かご６の内部がより明るい状態のときに防犯カメラ１２の画像の情報を取得することができる。その結果、防犯カメラ１２の汚れをより確実に検知することができる。 For example, the monitoring device 14 acquires the image information of the security camera 12 when the lighting device 10 is turned on when the door of the car 6 is closed and the inside of the car 6 is unattended. Therefore, the conditions for acquiring the image information of the security camera 12 can be made uniform, and the information of the image of the security camera 12 can be acquired when the inside of the car 6 is in a brighter state. As a result, the dirt on the security camera 12 can be detected more reliably.
