Next, in step S <b> 203, input / output with the elevator control circuit 20 in the elevator control device 2 is performed via the transmission line 106.

通信が正常に行われていないと判断された場合には、ステップＳ２０１へ進み、ＣＰＵ３２０１は、共通信号の入力先を、第１の伝送路１０１から第３の伝送路１０３に切り換える。次に、ステップＳ２０２では、パラレル−シリアル変換装置１２からの入力は、パラレル−シリアル変換装置１２→第２の伝送路１０２→伝送インターフェース１１→第３の伝送路１０３を介して行う。エレベーター制御装置２内のエレベーター制御回路２０との入出力は、ステップＳ２０３で伝送線１０６を介して行う   When it is determined that the communication is not normally performed, the process proceeds to step S <b> 201, and the CPU 3201 switches the input destination of the common signal from the first transmission path 101 to the third transmission path 103. In step S 202, the input from the parallel-serial conversion device 12 is performed via the parallel-serial conversion device 12 → the second transmission path 102 → the transmission interface 11 → the third transmission path 103. Input / output with the elevator control circuit 20 in the elevator control device 2 is performed via the transmission line 106 in step S203.

以上のように、この実施例１によれば、第１の伝送路１０１と、第２の伝送路１０２と、第３の伝送路１０３とを設けたので、第１の伝送路１０１が故障した場合でも、第２の伝送路１０２→伝送インターフェース１１を介して、必要な共通信号（例えば、フロアーカット情報、災害管制情報）を正常に群管理制御装置１内の群管理制御回路１０に入力できるとともに、第２の伝送路１０２→伝送インターフェース１１→第３の伝送路１０３→伝送インターフェース３１を介して、制御回路２０に必要な共通信号を正常にエレベーターの制御盤２０００内の制御装置２内の制御回路２０に入力できるという効果を奏する。   As described above, according to the first embodiment, since the first transmission path 101, the second transmission path 102, and the third transmission path 103 are provided, the first transmission path 101 has failed. Even in this case, necessary common signals (for example, floor cut information, disaster control information) can be normally input to the group management control circuit 10 in the group management control device 1 via the second transmission path 102 → the transmission interface 11. At the same time, the common signal necessary for the control circuit 20 is normally transmitted in the control device 2 in the elevator control panel 2000 via the second transmission path 102 → the transmission interface 11 → the third transmission path 103 → the transmission interface 31. There is an effect that it can be input to the control circuit 20.

また、群管理制御装置１が故障した場合においても、第１の伝送路１０１を介して、エレベーター制御装置２内の制御回路２０は、制御回路２０に必要な共通信号を入力できる。

Further, even when the group management control device 1 fails, the control circuit 20 in the elevator control device 2 can input a common signal necessary for the control circuit 20 via the first transmission path 101.
