Further, sampling module described in the sampling module includes sampling heated condition module and information storage module, institute The state of the control temperature of sampling heated condition module samples heating module is stated, described information memory module status information is stored up Deposit, the PLC calls the status information of sampling module storage, to judge to control heating module faster.

Further, the alarm module is alarmed when detection module detects that heating block temperature exceedes critical value, The alarm module is controlled by PLC.

Further, the display screen in the host computer shows that the operation information of whole system and the temperature of heating module become Change situation.

In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：

1. the utility model uses PLC and detection module, two are combined regulation are controlled to heating module, and Information is fed back, can realize that Millisecond controls heating module；

2. the utility model possesses sampling module, the operation of heating module and regulation process can be sampled, shape Into sampling model, PLC can call sampling model to realize that the faster startup of heating module is heated from sampling module；

3. the utility model uses single power plant module, entered respectively to PLC and heating module by transformer Row power supply, the electric voltage equalization regulation in whole system can be realized；

4. the utility model possesses human-computer interaction module, manual adjustment can be realized by the module so that whole system Use range it is bigger.
