Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1.The utility model provides a kind of novel intelligent PLC control system for induction heating power, PLC, power panel, drive plate that it comprises induction heating power master control borad and is attached thereto; Described PLC comprises the high-speed counter of CPU, analog input interface, touch display screen, sample devices real-time working frequency, and described PLC connects the status monitoring sensor be arranged on equipment by analog input interface.
The parameters such as described PLC adopts SIEMENS PLC, connects 50 status monitoring sensors by analog input interface, the given and temperature of the real-time voltage of collecting device, electric current, power, power, determine the real-time status of equipment with this; The real-time working frequency of sample devices is carried out by high-speed counter.Described PLC has higher sampling precision (16) and sample rate (grade) faster.
Described PLC is connected with alarm, and described alarm adopts syllogic alarm, and namely the glittering indication equipment of amber light carries out initialization, and initialization terminates rear amber light and do not work; Green light indication equipment works; When red indication equipment breaks down, now buzzer rings.
Described PLC is connected with external control interface, comprises power external controlled interface (4-20mA), starts and stops external controlled interface, fault IO interface etc.External control interface connects external control devices by connecting terminal block, the external signal inputted by external control devices realizes device start, stopping, power adjustments, increase the extensibility of induction heating power, facilitate and support the use with other automation equipments.
Described PLC is also connected with filter capacitor voltage detecting circuit, temperature sensing circuit, hydraulic pressure testing circuit etc.
Described master control borad is also connected with other signal plate, comprises phase shortage plate, voltage detecting plate, power external control plate, signal division board.
Principle of work of the present utility model: PLC converts the live signal that the collection of status monitoring sensor is come to corresponding digital signal, according to the signal such as startup, stopping, power adjustments sent equipment that duty and the external control interface of equipment receive, send corresponding response signal and pass to equipment.When master control borad works according to equipment, resonance current, the voltage signal of feedback, according to certain requirement, carry out waveform conversion, produce pwm pulse signal, pass to drive plate and open or turn off inversion device IGBT, and then carry out frequency-tracking, simultaneously also can the size of regulation output power.
