Example four:
FIG. 4 is a flow diagram illustrating a method for controlling a fleet round robin scheme applied in a first fleet, as shown in FIG. 3, in accordance with an exemplary embodiment, including:
s1, detecting whether a fault exists and receiving a fault signal or a non-fault signal sent by a second unit;
s2, when a non-fault signal of the second unit is input, the second unit is kept to be shut down, or when the second unit is judged to have no fault and a fault signal of the second unit is input, the second unit is controlled to be started, and the non-fault signal is sent to a second switch input module of the second unit through a first fault output module of the second unit;
s3, when the fault is judged, the power-off of the power-off control system is controlled, and a fault signal is sent to a second switch input module of a second unit through a first fault output module of the power-off control system;
it can be understood that the first unit receives a fault signal or a non-fault signal sent by the second unit, when the first unit receives the input of the non-fault signal of the second unit, the first unit keeps self-shutdown, when the first unit receives the input of the fault signal of the second unit and detects that the first unit is not faulty, the first unit controls self-startup and sends the non-fault signal to the second unit through the first fault output module of the first unit, and in the operation process, when the first unit is faulty, the first unit controls self-shutdown, sends the fault signal to the second unit through the first fault output module of the first unit, starts the second unit, and realizes the round-robin use of the first unit and the second unit.
Preferably, the detecting whether a fault exists or not is specifically:
whether an accident signal sent by a fault detection module of the device is received;
it can be understood that the fault detection module is configured to detect whether a fault exists in the unit itself, and a detection process of the fault detection module is conventional fault detection of an air conditioning unit, and the prior art is quite mature, and is not described herein in detail.
Preferably, the method further comprises the following steps:
after self fault is repaired, controlling a first switch input module to be started, so that a non-fault signal sent by a second unit can be received after self fault is repaired, and keeping a self shutdown state;

Preferably, the method further comprises the following steps:
when the power-on device is started, the power-on device controls the first switch input module to be closed, and shields a fault signal or a non-fault signal sent by the second unit;
it can be understood that, when the first unit is powered on, the first switch input module of the first unit is synchronously turned off, and the first unit stops receiving the fault signal or the non-fault signal sent by the second unit, because, in the process of operating the first unit, the second unit is faulty, the first unit continues to operate, if the fault of the second unit is recovered, the second unit sends the non-fault signal, at this time, the first unit will not be faulty but turned off because of the non-fault signal of the second unit, in order to avoid this situation, when the first unit operates, the signal of the second unit is shielded, which is why, in the above method, the first unit is in the power-off state when receiving the fault signal or the non-fault signal of the second unit, because in the power-on state, the first unit only sends the signal, but does not receive the signal.
Preferably, the method further comprises the following steps:
a time threshold T is preset, when the self starting operation time reaches the time threshold T, the self closing is controlled, and a fault signal is sent to the second unit through a self first fault output module, so that the second unit is started to operate;

Example five:
fig. 5 is a flow chart illustrating a method for controlling a unit round robin according to an exemplary embodiment, the method being applied to a second unit, as shown in fig. 4, and including:
s101, detecting whether a fault exists and receiving a fault signal or a non-fault signal sent by a first unit;
s201, when a non-fault signal of the first unit is input, the first unit is kept to be shut down, or when the first unit is judged to have no fault and a fault signal of the first unit is input, the first unit is controlled to be started up, and the non-fault signal is sent to a first switch input module of the first unit through a second fault output module of the first unit;
s301, when a fault is judged, the control device is controlled to shut down and sends a fault signal to a first switch input module of a first unit through a second fault output module;
it can be understood that the control principle of the second unit corresponds to the first unit, the second unit receives a fault signal or a non-fault signal sent by the first unit, when the second unit receives the input of the non-fault signal of the first unit, the second unit keeps self-shutdown, when the second unit receives the input of the fault signal of the first unit and detects that self is not fault, the second unit controls self-startup and sends the non-fault signal to the first unit through the second fault output module of the second unit, in the operation process, when self is fault, the second unit is controlled to self-shutdown, and sends the fault signal to the first unit through the second fault output module of the second unit, the first unit is started, and the round-robin use between the first unit and the first unit is realized.
Preferably, the first and second liquid crystal display panels are,
after self fault is repaired, controlling a second switch input module to be started, so that a non-fault signal sent by the first unit can be received after self fault is repaired, and keeping a self shutdown state;
it can be understood that, after the second unit closes itself due to a fault and starts the second unit by sending a fault signal, and the fault of the second unit is recovered, the second switch input module of the second unit is turned on, at this time, the second unit can receive a non-fault signal sent by the first unit, and the second unit continues to be turned off to wait for the fault signal of the first unit.
Preferably, the first and second liquid crystal display panels are,
when the mobile terminal is started, the second switch input module is controlled to be closed, and a fault signal or a non-fault signal sent by the first unit is shielded;
it can be understood that, similarly, the second unit also shields the signal of the first unit in the process of starting up and running, that is, no matter the first unit or the second unit, as long as starting up and running, only sends the signal to the other side, but does not receive the signal of the other side.
Preferably, the first and second electrodes are formed of a metal,
a time threshold T is preset, when the self starting operation time reaches the time threshold T, the self closing is controlled, and a fault signal is sent to the first unit through a self second fault output module, so that the first unit is started to operate;
it can be understood that a time threshold T is also preset in the second controller of the second unit, and when the startup operation time of the second unit reaches the time T, the second unit closes itself, and the simulated fault signal is sent to the first switch input module of the first unit through the second fault output module of itself, so as to realize active duty cycle between itself and the first unit.
The embodiment also discloses that, in an initial state, when the terminal control module does not start one unit but starts two units simultaneously, the first unit and the second unit operate simultaneously, and simultaneously shield a non-fault signal sent by the other unit, when one unit fails, the other unit operates continuously, and when the fault of the failed unit is recovered, the switch input module of the terminal control module is started, so that the terminal control module can receive the non-fault signal sent by the unit in operation, the terminal control module keeps shutting down, waits for the fault signal of the other unit, and enters the round robin method.
The embodiment also discloses that when the first unit and the second unit are in the fault state at the same time, the unit with the preferred fault recovery starts due to the fault signal sent by the unit in the fault state because the switch input module of the unit is turned on, and then the round robin method is subsequently entered.
