Recommended induction heating equipment for DSP+ FPGA full digital control melting and diathermy Compared with the advantages of traditional analog series resonance induction heating equipment:
1. In terms of core control :
For traditional analog power supplies, the parameters are determined by analog devices such as potentiometers. These devices are relatively affected by the environment, and temperature changes may cause parameter changes; the control process, data processing, and parameter storage of the DSP intelligent induction heating power supply are all in digital form The environment changes will not affect the calculation output process. Corresponding to the analog control system, the all-digital power supply has higher stability in different environments.
2. In terms of fault self-diagnosis and processing :
The DSP intelligent induction heating power supply displays the fault location and treatment method. When an error occurs or an alarm occurs in a special working condition, the touch screen will display the fault content. Click the help of the corresponding fault to find the corresponding fault solution. More than 90% of the common faults can be dealt with quickly by the operators, which greatly improves the production efficiency and reduces the dependence on the technical level of the operators.
DSP+ FPGA Full Digital Control Equipment Function Introduction:
1. Built-in process temperature PID closed loop program (optional), PID parameters can be set:
1) In many cases, the constant temperature operation mode can be used to automatically control the heating temperature of the workpiece and the output power of the power supply. After the temperature reaches the set value, the temperature is kept constant. Process PID temperature control program supports workpiece heating up to several grams and hundreds of tons, and its fast characteristics can be used for fast temperature control in seconds;
2) In the process type PID closed-loop program, the inert link transfer function is added to solve the measurement delay problem of the temperature signal. The exponential/logarithmic reduction operation can quickly restore the actual temperature of the workpiece. Now, whether it is thermocouple temperature measurement or infrared temperature measurement, excellent fast and no overshoot PID temperature control can be realized;
3) Temperature change rate controllable: Automatically raises and lowers temperature according to a certain slope.
2, With energy control features: The integration of power versus time can be controlled, which is very effective for constant temperature control, quenching, relatively fixed workpieces and processes, and can meet high level and complex process control requirements.
3, Accurate and fast internal control : Comprehensively improve system accuracy and speed, current display and control resolution is extremely high, stable output does not fluctuate, control speed is not affected;
4. The system adopts the self-innovated fast IGBT drive circuit: Compared with the current drive circuit, it can significantly improve the resonance waveform, reduce the dead time, further reduce the switching loss, and increase the stability of the frequency tracking. At the same time, each IGBT drive is With short circuit protection and under voltage protection;
5. Uninterrupted operation design: In the case of rapid switching or flickering of the power supply circuit or accidental protection, the device can perform automatic diagnosis and automatically return to normal operation state (automatic restart), which can avoid production loss caused by shutdown. ;
6, The grid voltage adapts to a wide range: can adapt to -30% - +10% of the grid fluctuation range (three-phase 380VAC models). And under the control of the DSP, the output operating value is not affected by the grid voltage fluctuations;
7. The output of the device is not equipped with transformer type, with transformer type, with transformer cord and long portable type, which can be used by our company according to the diversity of customer heating process and the special nature of the working condition. ;
8, Local fixed output function: Can be fixed in the digital fixed amount, the potentiometer shift will not affect the output, this function can be combined with the timer and energy control function;
10, Friendly human-computer interaction: Human-computer interaction can choose a variety of ways, LED indicator or digital tube display, touch screen display and control, text screen display, customers can choose as needed; comprehensive coverage from function implementation and operation settings The traditional mechanical button panel makes operation and maintenance simpler, more intuitive and more convenient;
