Detection signal and fault diagnosis adjustment signal carry out fault diagnosis next time.
For example shown in Fig. 6, in production line running, W1 electronic scales weight is detected by external disturbance, fluctuation exceedes
Input arranges value, fault diagnostic program is diagnosed to be the system failure and produces fault-signal, before exception handles exports a failure
Feedback adjustment signal and fault diagnosis adjustment signal, after system program receives failure feedforward adjustment signal, lock M1 meters immediately
The speed of motor is measured, prevents the powder flow caused by external disturbance to fluctuate excessive, fault diagnostic program receives fault diagnosis tune
After entire signal, whether to judge flow in the setting upper and lower zone of reasonableness of flow, the interference of W1 electronic scales weight disappears adjustment fault diagnosis
Flow is in zone of reasonableness, reset failure, while reset failure feedforward adjustment signal and fault diagnosis adjustment signal after losing or adjusting.
As shown in figure 5, input operation program is that input signal and failure feedback adjustment signal are carried out into calculation process, to produce
Raw input computing signal；Fault diagnostic program is to be examined input computing signal, feedback signal and fault diagnosis adjustment signal
It is disconnected, and produce fault-signal；Exception handles is to be processed fault-signal, and produces failure feedback adjustment signal, event
Barrier diagnosis adjustment signal and failure feedforward adjustment signal；System program is by input computing signal, feedback signal and failure feedforward
Adjustment signal is processed, and produces output signal.
It is corresponding with Fig. 5, in production line running, go out or exceed when detection signal (feedback signal) is low first
During preset signals (input signal) of regulation, fault diagnostic program is diagnosed to be the system failure and produces fault-signal, then failure
Fault-signal is processed and produces failure feedback adjustment signal to be adjusted to operation program, failure feedforward is input into respectively by processing routine
Entire signal to system program and fault diagnosis adjusts signal to fault diagnostic program, is input into operation program by input signal and failure
Feedback adjustment signal carries out calculation process, to produce input computing signal, system program will be input into computing signal, feedback signal and
Failure feedforward adjustment signal carries out treatment and produces output signal, and it is current that fault diagnostic program adjusts signal adjustment according to fault diagnosis
The parameter of preset signals, then fault diagnostic program combination input computing signal, detection signal and fault diagnosis adjustment signal enter
Row fault diagnosis next time.
For example shown in Fig. 6, in production line running, normal discharging detects P3 pressure sensor pressure to finished pot
More than input setting value, fault diagnostic program is diagnosed to be the system failure and produces fault-signal, the event of exception handles output one
Barrier feedback adjustment signal, failure feedforward adjustment signal and fault diagnosis adjustment signal, input operation program receive failure
After feedback adjustment signal, adjustment powder, the input setting flow of liquid material produce input computing signal, system program to receive event
After barrier feedforward adjustment signal and input computing signal, M1 measure motors, M2 measure motors, M3 feeding motors, M4 master are adjusted immediately
The speed of screw rod, while being regulated the speed by input computing signal dynamics, reduces speed of production, prevents P3 pressure from rising too fast.Therefore
After barrier diagnostic program receives fault diagnosis adjustment signal, whether adjustment fault diagnosis is adjusted to P3 pressure high more than setting pressure
Limit, next ring fault diagnosis and exception handles are performed if exceeding；When P3 pressure sensors pressure recovers normal, reset event
Barrier, while reset failure feedback adjustment signal, failure feedforward adjustment signal and fault diagnosis adjustment signal.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
The present invention has been described in detail, it will be understood by those within the art that：It still can be to foregoing each implementation
Technical scheme described in example is modified, or carries out equivalent to which part technical characteristic；And these modification or
Replace, do not make the spirit and scope of the essence disengaging various embodiments of the present invention technical scheme of appropriate technical solution.
