s101, judging whether the basic supercharger breaks down or not.
For example, in this embodiment, the manner of determining whether the basic supercharger fails may be:

The air outlet of the intercooler is connected with the air inlets of the A-side pipelines A1-AN and the B-side pipelines B1-BN, the air outlet of the A-side pipeline is connected with the air inlet of the basic supercharger T1, the air outlet of the A-side pipeline is connected with the air inlet of the controlled supercharger T2 through a gas valve VB1, the air outlet of the B-side pipeline is connected with the air inlet of the basic supercharger T3, and the air outlet of the B-side pipeline is connected with the air inlet of the controlled supercharger T4 through the gas valve VB2 (the cylinder of the engine M is also connected with the A-side pipeline and the B-side pipeline).
The air outlets of the basic supercharger T1 and the basic supercharger T3 are connected with the diffuser 1, and the air outlets of the controlled supercharger T2 and the controlled supercharger T4 are connected with the diffuser 2.
Referring to fig. 2, exemplarily, in this step, identifying a faulty basic supercharger to be disassembled and a basic supercharger pipeline to be repaired specifically include:
if the basic booster T1 fails, the basic booster T1 is identified as the failed basic booster to be disassembled, while the line associated with the basic booster T1 is identified as the basic booster line to be repaired.

acquiring the air pressure change rate of an air inlet of the controlled supercharger, and if the air pressure change rate of the air inlet of the controlled supercharger is greater than a set value, judging that the controlled supercharger fails;
and acquiring the air pressure change rate of the exhaust port of the controlled supercharger, and if the air pressure change rate of the exhaust port of the controlled supercharger is greater than a set value, judging that the controlled supercharger fails.
And S204, if the controlled supercharger fails, generating a controlled supercharger control instruction.
In this step, the controlled supercharger control command is used for controlling the valve group action of the fault controlled supercharger to actively isolate the fault controlled supercharger.

As an implementable embodiment, it may also be detected whether the valve group is successfully closed, and if the valve group is not successfully closed, a passive valve group control instruction is generated, where the passive valve group control instruction is used to identify a valve group to be closed.
Illustratively, when the controlled supercharger breaks down and the valve group cannot be automatically placed in the closed state, the designated valve group is manually controlled to be locked in the closed state according to the passive valve group control instruction, a passive isolation instruction is formed after the designated valve group is manually controlled to be locked in the closed state, and the isolated controlled supercharger is determined after the passive isolation instruction is received.
And S205, generating a supercharger operation mode adjustment log.
For example, when a main supercharger fails and the controlled supercharger is normal, the supercharger operation mode adjustment log may be:
one controlled supercharger and the normal main supercharger are marked as normally open superchargers, after the diesel engine is started, the normally open superchargers are controlled to be immediately put into operation, and if the operation working condition of the engine reaches the specified working condition, the rest controlled superchargers are controlled to be put into operation.

and marking the basic supercharger as a normally open supercharger, controlling the normally open supercharger to immediately work and operate after the diesel engine is started, and controlling the rest normal controlled superchargers to work if the operating condition of the engine reaches the specified working condition.

And the controlled supercharger control instruction is used for controlling at least one fault controlled supercharger to stop running when the diesel engine runs. And the supercharger operation mode adjustment log is used for stopping the diesel engine, disassembling the failed basic supercharger, trimming a pipeline of the basic supercharger, and controlling the rest normal basic supercharger and the controlled supercharger to operate according to a specified mode after the diesel engine is restarted.
On the basis of the schemes shown in fig. 1 and 3, the sequential supercharger control method further comprises the following steps:
if the basic supercharger and the controlled supercharger are normal, the basic supercharger is marked as a normally open supercharger, the normally open supercharger is controlled to work after the diesel engine is started, and if the running working condition of the engine reaches the specified working condition, the controlled supercharger is controlled to work.
Referring to fig. 2, if the basic supercharger and the controlled supercharger are normal, the basic superchargers T1 and T3 are immediately put into operation after the diesel engine is started, and the controlled superchargers T2 and T4 are put into operation in a designated order after the operation condition of the engine reaches a designated condition. For example, the controlled supercharger T2 is first placed into operation, and the controlled supercharger T4 is subsequently placed into operation.
Specifically, referring to fig. 2, after the diesel engine is successfully started, the basic superchargers T1 and T3 are immediately put into operation, and under a low-speed low-load operating condition, the controlled superchargers T2 and T4 do not operate, the air valve VA1, the air valve VA2, the gas valve VB1 and the gas valve VB2 are all in a closed state, so that exhaust gases on the a side and the B side are all and intensively supplied to the basic superchargers T1 and T3 respectively to drive the basic superchargers T1 and T3 to rotate, the basic superchargers T1 and T3 drive the gas compressors C1 and C3 respectively to press fresh air into an intercooler, and then the cylinders of the engine M are uniformly distributed.
When the rotating speed, the load and the supercharging pressure of the engine M are increased, an air valve VA1 and a gas valve VB1 are opened based on the operation working condition of the engine, so that the controlled supercharger T2 is put into operation; the air valve VA2 and the gas valve VB2 are opened to activate the controlled supercharger T4.
