- each processing step will be described. First, the processing content of the car controller 11 will be described with reference to FIG.
- Step S301 The communication determination unit 202 in the car controller determines whether or not the communication with the control controller 14 is abnormal. If the communication is abnormal (Yes), the process proceeds to step 302, and if the communication is not abnormal (No), the process proceeds to step 303.
- Step S302 The car controller 11 stores the detection state of the detection sensor 9 determined by the detection determination unit 201 as the "current detection state” in the detection state memory 203. If the "current detection state” already stores the information of the detection state one cycle before (that is, 1 ms ago), the information is simultaneously moved to the "1 ms previous detection state”. Similarly, all the detection states stored in the "(N) ms pre-detection state” move to the "(N + 1) ms pre-detection state” (N is a natural number). Therefore, the detection state memory 203 stores the log in the detection state of the detected body 10 from the occurrence of the communication abnormality to the present. After step S302, this flow ends.
- Step S303 The car controller 11 transmits information on the detection state of the detection sensor 9 determined by the detection determination unit 201 to the control controller 14. Then, the process proceeds to step S304.
- Step S304 The car controller 11 determines whether or not the detection state information is stored in the detection state memory 203. If the detection status information is stored (Yes), the process proceeds to step S305, and if the detection status information is not stored (No), this flow ends.
- Step S305 The car controller 11 transmits all the detection state information stored in the detection state memory 203 to the control controller 14.
- the information to be transmitted is arranged in order from the current detection state, and the control controller 14 makes it possible to determine how many ms before the information of each detection state is the detection state. Then, the process proceeds to step S306.
- step S305 when a communication abnormality occurs, the detection state of the detected body 10 from a predetermined time before being detected by the detection sensor 9 to the present is memorized starting from the time when the communication abnormality occurs, and the communication abnormality is resolved. If so, the stored detection state of the detected body 10 is transmitted to the control controller 14.
- Step S306 The car controller 11 clears (erases) all the logs related to the detection state stored in the detection state memory 203. After that, this flow ends.
- Step S401 The communication determination unit 205 in the control controller determines whether or not the communication with the car controller 11 is abnormal. If the communication is abnormal (Yes), the process proceeds to step S402, and if the communication is not abnormal (No), the process proceeds to step S405.
- Step S402 The control controller 14 stores the car position information calculated by the car position calculation unit 204 as the "current car position" in the car position memory 209. If the "current car position” already stores the information on the car position one cycle before (that is, 1 ms before), it is moved to the "1 ms previous car position” at the same time. Similarly, all the detection state information stored in the "(N) ms front car position” moves to the "(N + 1) ms front detection state” (N is a natural number). Therefore, the car position memory 209 stores a log of the car position from the occurrence of the communication abnormality to the present. After step S402, the process proceeds to step S403.
- Step S403 The control controller 14 determines whether or not the car 1 is running based on the pulse signal from the encoder 8. If the car 1 is running (Yes), the process proceeds to step S404, and if not (No), this flow ends.
- Step S404 The control controller 14 slows down the rotation speed of the motor 4, gently decelerates the car 1, and stops it. If communication is abnormal, the car will be stopped for safety. However, in order to suppress the anxiety given to the passengers as much as possible, the car 1 is not suddenly stopped, but is gradually decelerated and then stopped. After the stop, the elevator operation is stopped. This flow ends after step S404.
- Step S405 The detection abnormality determination unit 206 determines the detection state of the detected body 10 received from the car controller 11, the current position of the car 1, and the detected body 10 on each floor stored in the floor position memory 208.
- the presence or absence of abnormality in the detection sensor 9 or the detected body 10 is determined based on the position (lower end position). Specifically, when there is a current car position between the lower end position of the detected body 10 on any floor and the position higher by the length of the detected body 10, the detection sensor 9 detects the detected body 10. It is determined that the detection sensor 9 or the object to be detected 10 has an abnormality if it is not detected and if the car position is outside the above range. If it is determined that the detection abnormality is (Yes), the process proceeds to step S406, and if it is not a detection abnormality (No), the process proceeds to step S407.
- Step S406 When it is determined that the detection sensor 9 or the object to be detected 10 has an abnormality, the control controller 14 slows down the rotation speed of the motor 4 and gently decelerates and stops the car 1. After the stop, the elevator operation is stopped. This flow ends after step S406.
- Step S407 The control controller 14 determines whether or not the car controller 11 has received the detection status information log (transmitted in step S305) stored in the detection status memory 203. If it is received (Yes), the process proceeds to step S408, and if it is not received (No), this flow ends.
- Step S408 The detection abnormality determination unit 206 includes a log of the detection status received from the car controller 11, a log of the car position information stored in the car position memory 209, and each floor stored in the floor position memory 208. Based on the information of the lower end position of the detected body 10, the abnormality of the detection sensor 9 or the detected body 10 during the occurrence of the communication abnormality is determined. Judgment is performed in step S405 by a logic in which the detection state is replaced with "(N) ms front detection state” and the car position is replaced with "(N) ms front car position" (N is a natural number), and all logs are determined. To carry out. If any of the logs is determined to be abnormal (Yes), the process proceeds to step S409, and if not (No), the process proceeds to step S410.
- Step S409 The control controller 14 slows down the rotation speed of the motor 4, gently decelerates the car 1, and stops it. After the stop, the elevator operation is stopped. After step S409, the process proceeds to step S411.
- Step S410 The control controller 14 resumes the operation of the elevator. When reaching this step, it is a case where a communication abnormality has been detected up to one cycle before, and at this time, the control controller 14 suspends the operation of the elevator in step S404. In steps S405 and S408, it is determined that no detection abnormality has occurred at present and during the communication abnormality, so that the elevator operation is restarted. After step S410, the process proceeds to step S411.
- Step S411 The control controller 14 erases (clears) all the logs of the car position information stored in the car position memory 209. After that, this flow ends.
- the car is put into hibernation by detecting an abnormality in communication and sensors.
- the car controller 11 stores the log of the detection state information in the detection state memory 203 (step S302), and the control controller 14 stores the log of the car position information in the car position memory.
- Step S402 after the communication is restored to normal, the control controller 14 determines the detection abnormality using these (step S408), so that the detection abnormality during the communication abnormality can be detected.

図３は、本発明の実施例に係るかごコントローラ１１の処理内容を示すフローチャートである。図４は、本発明の実施例に係る制御コントローラ１４の処理内容を示すフローチャートである。
FIG. 3 is a flowchart showing the processing contents of the car controller 11 according to the embodiment of the present invention. FIG. 4 is a flowchart showing the processing contents of the control controller 14 according to the embodiment of the present invention.
図３及び図４のフローは周期的に実行される。本実施例では、周期は１ｍｓそしている。以下、処理ステップごとに説明する。まず、かごコントローラ１１の処理内容について、図３を用いて説明する。
The flow of FIGS. 3 and 4 is executed periodically. In this example, the period is 1 ms. Hereinafter, each processing step will be described. First, the processing content of the car controller 11 will be described with reference to FIG.
ステップＳ３０１：かごコントローラ内通信判定部２０２は、制御コントローラ１４との通信が異常か否か判定する。通信が異常の場合（Ｙｅｓ）、ステップ３０２に移り、通信が異常ではない場合（Ｎｏ）、ステップ３０３に移る。
Step S301: The communication determination unit 202 in the car controller determines whether or not the communication with the control controller 14 is abnormal. If the communication is abnormal (Yes), the process proceeds to step 302, and if the communication is not abnormal (No), the process proceeds to step 303.
ステップＳ３０２：かごコントローラ１１は、検出判定部２０１で判定した検出センサ９の検出状態を「現在検出状態」として検出状態メモリ２０３に格納する。既に「現在検出状態」に１周期前（すなわち１ｍｓ前）の検出状態の情報が格納されている場合は、その情報を同時に「１ｍｓ前検出状態」に移動する。同様に、「（Ｎ）ｍｓ前検出状態」に格納されている検出状態は全て「（Ｎ＋１）ｍｓ前検出状態」に移動する（Ｎは自然数）。したがって、検出状態メモリ２０３には、通信異常が発生してから現在に至るまでの被検出体１０の検出状態におけるログが格納される。ステップＳ３０２の後、本フローを終了する。
Step S302: The car controller 11 stores the detection state of the detection sensor 9 determined by the detection determination unit 201 as the "current detection state" in the detection state memory 203. If the "current detection state" already stores the information of the detection state one cycle before (that is, 1 ms ago), the information is simultaneously moved to the "1 ms previous detection state". Similarly, all the detection states stored in the "(N) ms pre-detection state" move to the "(N + 1) ms pre-detection state" (N is a natural number). Therefore, the detection state memory 203 stores the log in the detection state of the detected body 10 from the occurrence of the communication abnormality to the present. After step S302, this flow ends.
ステップＳ３０３：かごコントローラ１１は、検出判定部２０１で判定した検出センサ９の検出状態の情報を制御コントローラ１４に送信する。その後、ステップＳ３０４に移る。
Step S303: The car controller 11 transmits information on the detection state of the detection sensor 9 determined by the detection determination unit 201 to the control controller 14. Then, the process proceeds to step S304.
ステップＳ３０４：かごコントローラ１１は、検出状態メモリ２０３に検出状態の情報が格納されているかを判定する。検出状態の情報が格納されている場合（Ｙｅｓ）、ステップＳ３０５に移り、検出状態の情報が格納されていない場合（Ｎｏ）は本フローを終了する。
Step S304: The car controller 11 determines whether or not the detection state information is stored in the detection state memory 203. If the detection status information is stored (Yes), the process proceeds to step S305, and if the detection status information is not stored (No), this flow ends.
ステップＳ３０５：かごコントローラ１１は、検出状態メモリ２０３に格納されている検出状態の情報を全て制御コントローラ１４に送信する。送信する情報は、現在検出状態から順に並べて行い、制御コントローラ１４にて各検出状態の情報が何ｍｓ前の検出状態か判別可能にする。その後、ステップＳ３０６に移る。ステップＳ３０５では、通信異常が発生した場合、通信異常が発生した時点を起点とし、検出センサ９によって検出される所定時間前から現在までの被検出体１０の検出状態を記憶し、通信異常が解消され場合、記憶された被検出体１０の検出状態を制御コントローラ１４に送信する。
Step S305: The car controller 11 transmits all the detection state information stored in the detection state memory 203 to the control controller 14. The information to be transmitted is arranged in order from the current detection state, and the control controller 14 makes it possible to determine how many ms before the information of each detection state is the detection state. Then, the process proceeds to step S306. In step S305, when a communication abnormality occurs, the detection state of the detected body 10 from a predetermined time before being detected by the detection sensor 9 to the present is memorized starting from the time when the communication abnormality occurs, and the communication abnormality is resolved. If so, the stored detection state of the detected body 10 is transmitted to the control controller 14.
ステップＳ３０６：かごコントローラ１１は、検出状態メモリ２０３に格納されている検出状態に関するログを全てクリア（消去）する。その後、本フローを終了する。
Step S306: The car controller 11 clears (erases) all the logs related to the detection state stored in the detection state memory 203. After that, this flow ends.
次に制御コントローラ１４の処理内容について、図４を用いて説明する。
Next, the processing content of the control controller 14 will be described with reference to FIG.
ステップＳ４０１：制御コントローラ内通信判定部２０５は、かごコントローラ１１との通信が異常か否か判定する。通信が異常の場合（Ｙｅｓ）、ステップＳ４０２に移り、通信が異常ではない場合（Ｎｏ）、ステップＳ４０５に移る。
Step S401: The communication determination unit 205 in the control controller determines whether or not the communication with the car controller 11 is abnormal. If the communication is abnormal (Yes), the process proceeds to step S402, and if the communication is not abnormal (No), the process proceeds to step S405.
ステップＳ４０２：制御コントローラ１４は、乗りかご位置算出部２０４で算出した乗りかご位置の情報を「現在乗りかご位置」として乗りかご位置メモリ２０９に格納する。既に「現在乗りかご位置」に１周期前（すなわち１ｍｓ前）の乗りかご位置の情報が格納されている場合は、それを同時に「１ｍｓ前乗りかご位置」に移動する。同様に、「（Ｎ）ｍｓ前乗りかご位置」に格納されている検出状態の情報は全て「（Ｎ＋１）ｍｓ前検出状態」に移動する（Ｎは自然数）。したがって、乗りかご位置メモリ２０９には、通信異常が発生してから現在に至るまでの乗りかご位置のログが格納される。ステップＳ４０２の後、ステップＳ４０３に移る。
Step S402: The control controller 14 stores the car position information calculated by the car position calculation unit 204 as the "current car position" in the car position memory 209. If the "current car position" already stores the information on the car position one cycle before (that is, 1 ms before), it is moved to the "1 ms previous car position" at the same time. Similarly, all the detection state information stored in the "(N) ms front car position" moves to the "(N + 1) ms front detection state" (N is a natural number). Therefore, the car position memory 209 stores a log of the car position from the occurrence of the communication abnormality to the present. After step S402, the process proceeds to step S403.
ステップＳ４０３：制御コントローラ１４は、エンコーダ８からのパルス信号に基づき乗りかご１が走行中か否かを判定する。乗りかご１が走行中の場合（Ｙｅｓ）はステップＳ４０４に移り、そうでない場合（Ｎｏ）は本フローを終了する。
Step S403: The control controller 14 determines whether or not the car 1 is running based on the pulse signal from the encoder 8. If the car 1 is running (Yes), the process proceeds to step S404, and if not (No), this flow ends.
ステップＳ４０４：制御コントローラ１４は、モータ４の回転速度を落とし、乗りかご１を緩やかに減速し、停止させる。通信異常時は安全のために乗りかごの走行を中止する。ただし、乗客へ与える不安を極力抑えるために乗りかご１を急停止させることなく、緩やかに減速させたのちに停止させるものとする。停止後はエレベーターの運転を休止する。ステップＳ４０４後に本フローを終了する。
Step S404: The control controller 14 slows down the rotation speed of the motor 4, gently decelerates the car 1, and stops it. If communication is abnormal, the car will be stopped for safety. However, in order to suppress the anxiety given to the passengers as much as possible, the car 1 is not suddenly stopped, but is gradually decelerated and then stopped. After the stop, the elevator operation is stopped. This flow ends after step S404.
ステップＳ４０５：検出異常判定部２０６は、かごコントローラ１１からの受信した被検出体１０の検出状態と、乗りかご１の現在位置、および階床位置メモリ２０８に格納された各階の被検出体１０の位置（下端位置）に基づいて検出センサ９または被検出体１０の異常の有無を判定する。具体的には、いずれかの階の被検出体１０の下端位置から被検出体１０の長さ分高い位置までの間に、現在乗りかご位置がある場合に検出センサ９が被検出体１０を検出していないこと、および乗りかご位置が上記範囲以外の場合に検出していることを、検出センサ９または被検出体１０に異常があると判定する。検出異常と判定される場合（Ｙｅｓ）はステップＳ４０６に移り、検出異常でない場合（Ｎｏ）はステップＳ４０７に移る。
Step S405: The detection abnormality determination unit 206 determines the detection state of the detected body 10 received from the car controller 11, the current position of the car 1, and the detected body 10 on each floor stored in the floor position memory 208. The presence or absence of abnormality in the detection sensor 9 or the detected body 10 is determined based on the position (lower end position). Specifically, when there is a current car position between the lower end position of the detected body 10 on any floor and the position higher by the length of the detected body 10, the detection sensor 9 detects the detected body 10. It is determined that the detection sensor 9 or the object to be detected 10 has an abnormality if it is not detected and if the car position is outside the above range. If it is determined that the detection abnormality is (Yes), the process proceeds to step S406, and if it is not a detection abnormality (No), the process proceeds to step S407.
ステップＳ４０６：検出センサ９または被検出体１０に異常があると判定された場合、制御コントローラ１４は、モータ４の回転速度を落とし、乗りかご１を緩やかに減速し、停止させる。停止後はエレベーターの運転を休止する。ステップＳ４０６後に本フローを終了する。
Step S406: When it is determined that the detection sensor 9 or the object to be detected 10 has an abnormality, the control controller 14 slows down the rotation speed of the motor 4 and gently decelerates and stops the car 1. After the stop, the elevator operation is stopped. This flow ends after step S406.
ステップＳ４０７：制御コントローラ１４は、かごコントローラ１１から検出状態メモリ２０３に格納されていた検出状態の情報のログ（ステップＳ３０５にて送信）を受信しているか否か判定する。受信している場合（Ｙｅｓ）、ステップＳ４０８に移り、受信していない場合（Ｎｏ）、本フローを終了する。
Step S407: The control controller 14 determines whether or not the car controller 11 has received the detection status information log (transmitted in step S305) stored in the detection status memory 203. If it is received (Yes), the process proceeds to step S408, and if it is not received (No), this flow ends.
ステップＳ４０８：検出異常判定部２０６は、かごコントローラ１１から受信した検出状態のログと、乗りかご位置メモリ２０９に格納された乗りかごの位置情報のログ、および階床位置メモリ２０８に格納された各階の被検出体１０の下端位置の情報に基づいて通信異常発生中における検出センサ９または被検出体１０の異常を判定する。判定は、ステップＳ４０５において、検出状態を「（Ｎ）ｍｓ前検出状態」、乗りかご位置を「（Ｎ）ｍｓ前乗りかご位置」に置き換えたロジックで行い（Ｎは自然数）、全てのログに対し実施する。いずれかのログで異常と判定される場合（Ｙｅｓ）はステップＳ４０９に移り、そうでない場合（Ｎｏ）はステップＳ４１０に移る。
Step S408: The detection abnormality determination unit 206 includes a log of the detection status received from the car controller 11, a log of the car position information stored in the car position memory 209, and each floor stored in the floor position memory 208. Based on the information of the lower end position of the detected body 10, the abnormality of the detection sensor 9 or the detected body 10 during the occurrence of the communication abnormality is determined. Judgment is performed in step S405 by a logic in which the detection state is replaced with "(N) ms front detection state" and the car position is replaced with "(N) ms front car position" (N is a natural number), and all logs are determined. To carry out. If any of the logs is determined to be abnormal (Yes), the process proceeds to step S409, and if not (No), the process proceeds to step S410.
ステップＳ４０９：制御コントローラ１４は、モータ４の回転速度を落とし、乗りかご１を緩やかに減速し、停止させる。停止後はエレベーターの運転を休止する。ステップＳ４０９後、ステップＳ４１１に移る。
Step S409: The control controller 14 slows down the rotation speed of the motor 4, gently decelerates the car 1, and stops it. After the stop, the elevator operation is stopped. After step S409, the process proceeds to step S411.
ステップＳ４１０：制御コントローラ１４は、エレベーターの運転を再開する。本ステップに至るとき、1周期前まで通信異常を検出していた場合であり、このとき、制御コントローラ１４はステップＳ４０４にてエレベーターの運転を休止している。ステップＳ４０５，Ｓ４０８にて、現在および通信異常中に検出異常が発生していないと判定されたため、エレベーターの運転を再開する。ステップＳ４１０の後、ステップＳ４１１に移る。
Step S410: The control controller 14 resumes the operation of the elevator. When reaching this step, it is a case where a communication abnormality has been detected up to one cycle before, and at this time, the control controller 14 suspends the operation of the elevator in step S404. In steps S405 and S408, it is determined that no detection abnormality has occurred at present and during the communication abnormality, so that the elevator operation is restarted. After step S410, the process proceeds to step S411.
ステップＳ４１１：制御コントローラ１４は、乗りかご位置メモリ２０９に格納されている乗りかご位置情報のログを全て消去（クリア）する。その後、本フローを終了する。
Step S411: The control controller 14 erases (clears) all the logs of the car position information stored in the car position memory 209. After that, this flow ends.
以上のように、本実施例では通信、センサの異常を検出して乗りかごを休止状態にする。このように、通信異常時に、かごコントローラ１１が検出状態メモリ２０３に検出状態の情報のログを格納し（ステップＳ３０２）、制御コントローラ１４が乗りかご位置メモリに乗りかご位置の情報のログを格納し（ステップＳ４０２）、通信が正常復帰した後に、これらを用いて制御コントローラ１４が検出異常を判定する（ステップＳ４０８）ことで、通信異常中の検出異常を発見することができる。
As described above, in this embodiment, the car is put into hibernation by detecting an abnormality in communication and sensors.
