Firstly, the target radio frequency power supply is detected in real time through a feedback quantity detection module in the intelligent control system, so that a real-time signal of the target radio frequency power supply, namely the target synchronous signal, is obtained. The target radio frequency power supply is any radio frequency power supply which is started and controlled by the intelligent control system, and is exemplified by a certain high-power radio frequency power supply in the laser processing industry. The feedback quantity detection module is embedded in the intelligent control system and is used for detecting the radio frequency power supply automatically controlled by the intelligent control system, related electric signals, voltage signals, current signals and the like in the circuit of the radio frequency power supply in real time. And by detecting the target synchronous signal, a signal basis is provided for the subsequent determination of the starting control decision of the target radio frequency power supply.

Specifically, after the intelligent control system detects the target synchronous signal, the intelligent control system analyzes and judges the target synchronous signal so as to determine whether to start and control the target radio frequency power supply.

Specifically, firstly, a historical synchronous signal time sequence is acquired based on big data, and the historical synchronous signal time sequence is screened, so that a historical signal data set is obtained. The history signal data set is used for training the synchronous signal support vector machine. And then extracting first historical signal data in the historical signal data set, and manually analyzing the first historical signal data to obtain the state condition of the target radio frequency power supply corresponding to the first historical signal data, namely, the state condition is used as the first state label. And obtaining a historical state label set based on the first state label, wherein the historical state label set corresponds to the historical signal data set one by one, and finally combining the historical state label set with the historical signal data set to obtain training data. And finally constructing the synchronous signal support vector machine based on the training data. And finally judging whether the target radio frequency power supply reaches a preset state requirement or not based on the target output result. The preset state requirement is that the target radio frequency power supply is in a starting state.
By constructing the synchronous signal support vector machine, the technical aim of providing a model foundation for intelligently analyzing the target synchronous signal of the target radio frequency power supply is achieved, the intelligent degree of signal analysis is improved, and the technical effects of improving the reliability and accuracy of state judgment of the target radio frequency power supply are achieved.
Further, as shown in fig. 3, step S220 of the present invention includes:
step S221: obtaining a signal screening processor, wherein the signal screening processor comprises a first screening layer and a second screening layer;
step S222: screening the target signal time sequence through the first screening layer to obtain a first screening result;
further, the invention comprises the following steps:
step S2221: extracting a first signal in the target signal time sequence, wherein the first signal has a first time sequence characteristic;
step S2222: determining a first adjacent time sequence and a second adjacent time sequence based on the first time sequence characteristic;
step S2223: sequentially matching the first adjacent signal of the first adjacent time sequence and the second adjacent signal of the second adjacent time sequence;
step S2224: calculating a first adjacent signal difference based on the first adjacent signal and the first signal, and calculating a second adjacent signal difference based on the second adjacent signal and the first signal;
step S2225: judging whether the first adjacent signal difference and the second adjacent signal difference meet a preset signal difference threshold value or not;
step S2226: if not, adding the first signal to the first screening result.
Step S223: extracting a preset lattice hopping scheme in the second screening layer, and carrying out secondary screening on the first screening result based on the preset lattice hopping scheme to obtain a second screening result;
step S224: and taking the second screening result as the target signal data set.
Specifically, before screening the target signal sequence, a signal screening processor is first constructed for intelligently screening and analyzing the target signal sequence. The signal screening processor comprises a first screening layer and a second screening layer.
And screening the target signal time sequence through the first screening layer in the signal screening processor to obtain the first screening result. And then taking the first screening result as input information of the second screening layer, intelligently screening by the second screening layer to obtain the second screening result, and taking the second screening result as a final processing result of the signal screening processor, namely, the target signal data set. When the first screening layer performs screening, each signal in the target signal time sequence is sequentially subjected to comparison analysis, for example, the first signal in the target signal time sequence is randomly extracted, meanwhile, the first time sequence characteristic of the first signal is extracted, further, based on the first time sequence characteristic, a corresponding previous time sequence, namely, a first adjacent time sequence and a corresponding next time sequence, namely, the second adjacent time sequence, then = a first adjacent signal and a second adjacent signal which are sequentially matched with the first adjacent time sequence, the first adjacent signal and the first signal are compared, further, a first adjacent signal difference is obtained through calculation, the second adjacent signal and the first signal are compared, and further, a second adjacent signal difference is obtained through calculation. And finally, judging whether the first adjacent signal difference and the second adjacent signal difference meet a preset signal difference threshold value. The preset signal difference threshold is a maximum difference range between signals obtained by continuous signal detection which is determined by analysis in advance based on historical signal data and operation experience of related technicians. And when the judging result shows that the first adjacent signal difference and the second adjacent signal difference do not meet the preset signal difference threshold, indicating that the extracted first signal has larger variation, and adding the first signal to the first screening result for an analysis basis of an intelligent control system.
Further, when the second screening layer performs secondary screening on the first screening result, a preset tab scheme in the second screening layer is called first, and then the second screening result is subjected to secondary screening based on the preset tab scheme, so that the second screening result is obtained. The preset tab scheme refers to the minimum interval times between extracting abnormal signals. Exemplary, for example, after the signal a is added to the first filtering result, a signal B also meets the condition of being added to the first filtering result, so that the number of intervals between the signal B and the signal a is calculated, and when the corresponding number of intervals is smaller than the number of intervals in the preset tab scheme, the signal B is removed. And finally, taking the second screening result obtained after the secondary screening as the target signal data set.
The target signal data set is obtained through screening, so that the aim of providing an input data basis for the subsequent intelligent analysis of the support vector machine is fulfilled, and the technical effects of improving the system processing efficiency and the system performance are achieved.
Step S300: if yes, calling a preset control scheme, extracting a first preset control scheme in the preset control scheme, and performing starting control on a target thyristor to obtain a steadily rising voltage;
step S400: if the steadily rising voltage reaches a preset rated voltage, extracting a second preset control scheme in the preset control schemes;
step S500: starting control is carried out on the target current based on the second preset control scheme, and a current control result is obtained;
specifically, after the system intelligently judges that the current state of the target radio frequency power supply meets the preset state requirement, the intelligent control system automatically invokes a preset control scheme, extracts a first preset control scheme in the preset control scheme, and performs starting control on the target thyristor to obtain a steadily rising voltage. Further, when the steadily rising voltage rises to meet the preset rated voltage, the system automatically extracts a second preset control scheme in the preset control schemes, and starts and controls the target current based on the second preset control scheme to obtain a current control result. For example, if a certain thyristor module is connected between a power frequency power supply and a transformer, when a main circuit is started, a thyristor can control voltage output, the voltage output by the thyristor can gradually rise, and along with the rising of the output voltage of the thyristor, the voltage of the transformer gradually rises until the thyristor is completely conducted. When the high-voltage transformer works at rated voltage, smooth starting can be realized. Thereby reducing the starting current and avoiding the tripping of the starting current. The soft start target of the target radio frequency power supply is realized, the heating phenomenon of the system is slowed down, and the control safety of the system is improved.
Step S600: determining a target trigger circuit according to the current control result, and preprocessing the target trigger circuit to obtain a target trigger circuit preprocessing result;
further, as shown in fig. 4, the invention comprises the following steps:
step S610: obtaining a pulse transformer, wherein the pulse transformer comprises a transistor, a voltage stabilizing tube and a diode;
step S620: and isolating the target trigger circuit through the transistor, the voltage stabilizing tube and the diode to obtain a target trigger circuit preprocessing result.
Specifically, to ensure safe and stable operation of the trigger circuit, the trigger circuit and the main circuit are generally separated, and a low-voltage direct-current power supply in the trigger circuit is relatively independently supplied. And analyzing the current control result to determine a current trigger circuit of the intelligent control system, namely the target trigger circuit, so as to preprocess the target trigger circuit and obtain a target trigger circuit preprocessing result. Firstly, a pulse transformer is called, and the target trigger circuit is isolated through a transistor, a voltage stabilizing tube and a diode in the pulse transformer, namely, the interference factors of the trigger circuit and a control circuit are reduced through electric isolation, so that the target trigger circuit preprocessing result is obtained. The transistor is used for preventing high voltage breakdown at the moment of switching off the transistor, and the diode is used for preventing high voltage secondarily induced by the pulse transformer from being loaded to the grid electrode of the transistor when the transistor is switched off.
Step S700: and starting and controlling the target radio frequency power supply based on the target trigger circuit preprocessing result.
Further, step S700 of the present invention includes:
step S710: the target trigger circuit is detected in real time through the feedback quantity detection module, and the real-time state of the trigger circuit is obtained;
step S720: the trigger circuit real-time state comprises trigger circuit real-time voltage and trigger circuit real-time current;
step S730: judging and analyzing the trigger circuit real-time voltage and the trigger circuit real-time current to obtain real-time judgment information;
step S740: and starting control is carried out on the target radio frequency power supply based on the real-time judgment information.
Specifically, when the target radio frequency power supply is started and controlled based on the target trigger circuit preprocessing result, the target trigger circuit is detected in real time through the feedback quantity detection module, and the real-time state of the trigger circuit is obtained. And then sequentially extracting the trigger circuit real-time voltage and the trigger circuit real-time current in the trigger circuit real-time state, further judging and analyzing the trigger circuit real-time voltage and the trigger circuit real-time current, judging whether the trigger circuit real-time voltage is in a preset voltage range or not, judging whether the trigger circuit real-time current is in a preset current range or not, and finally obtaining the real-time judgment information. When the real-time judgment information shows that the real-time voltage of the trigger circuit and the real-time current of the trigger circuit are in the preset normal range, the system starts and controls the target radio frequency power supply, so that potential safety hazards caused by voltage or current overload in the trigger circuit are effectively avoided, and the control stability of the system is improved.
