以下詳細に説明する。In the conventional system, the central controller 10 activates the autonomous operation of one of the trunk control signal processing devices 30 and 31 and puts the other in an idle state, and if the standby trunk control signal processing device is affected, it activates the autonomous operation. Trunk control signal processing devices 30 and 31 are installed in the controlled device TO to prevent the controlled device TO from receiving the erroneous control signal and malfunctioning even if it sends an erroneous control signal to the controlled device 1.0 due to runaway. A system switching signal storage and display device 20 is installed to instruct which one of the control signals should be received. or 131, which system is currently in use is notified to the controlled device TO via the system designated control line. That is, in the conventional system, the above-mentioned storage and display device 20 is installed as an independent device, and a power supply device 42 is installed that is independent of both the duplexing sections and supplies power to the device 20, so that the trunk control signal processing device 30 and the ，
Hardware devices for system switching, such as ensuring a system switching function even in the event of a failure of the power supplies 40 and 41 that supply power to the 31, have become expensive. The present invention enables the function of a system switching signal storage and display device that is expensive to be installed as a common unit for a device with a duplex configuration to be transferred to the duplex device without installing it independently from the duplex device. By distributing the distribution to each system of the heavy-duty section, we aim to reduce the cost of the system, and also
Even if the autonomous operation of the non-active system of the heavy equipment goes out of control, the controlled equipment that is under its control will not be affected.
This will be explained in detail below.

The system switching signal accumulation display circuit 6
0 and 61 mutually control the other's active system display signal accumulation by receiving the active system designation through the control line 150 or 1.
51, for one trunk device 70, one of the system switching signal accumulation and display circuits 60 or 61 is connected to the active system designated control line 140 or 14.

方式が実現できる利点を有する。Based on the notification signal, the trunk device 70 receives an operation control signal from only one of the trunk control signal processing devices 50 or 51 via the trunk operation control line 120 or 121. FIG. 3 shows an embodiment of a system switching circuit for realizing the system switching system according to the present invention, in which circuits consisting of flip-flops and the like are distributed in each system of the duplex component.
The meaning of each number in FIG. 3 is the same as that in FIG. 2. As is clear from the above embodiments, the present invention has two
For systems that include multiple devices and usually require system switching or system instructions to use one of them as the active system, a dedicated device for realizing the switching function and power supply to the dedicated device. By distributing the switching function within the duplex configuration device without installing a dedicated power supply for switching, there is an advantage that the system switching system can be realized at low cost and with simple hardware.
