Saving the fundamental policy that the energy is country, meaning of the present invention is to utilize employing PLC to control system
System, runs relevant parameter all include PLC control system, overall arrangement, section in by boiler, air stove
Learn and arrange, auto-control, intuitively show, it is achieved save the purpose of the energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention,
Detailed description of the invention
As it is shown in figure 1, the present invention includes combustion chamber draft sensor 1, oxygen content sensor 10, outdoor
Temperature sensor 9, PLC control cabinet 2, air-introduced machine converter 3, blower variable frequency device 5, fire grate become
Frequently device 8;The signal output part of combustion chamber draft sensor 1 and the first input port of PLC control cabinet 2
Connecting, the signal output part of oxygen content sensor 10 is connected with the second input port of PLC control cabinet 2,
The signal output part of outdoor temperature sensor 9 is connected with the 3rd input port of PLC control cabinet 2;PLC
First signal output port of switch board 2 connects the signal input part of air-introduced machine converter 3, air-introduced machine
The signal output part of converter 3 is connected with the controlled end of air-introduced machine 4;Second letter of PLC control cabinet 2
Number output port connects the signal input part of blower variable frequency device 5, and the signal of blower variable frequency device 5 is defeated
Go out end to be connected with the controlled end of aerator 6;3rd signal output port of PLC control cabinet connects fire grate
The signal input part of converter 8, the signal output part of fire grate converter 8 connects with the controlled end of fire grate 7
Connect.
The present invention is by oxygen-containing for the smoke evacuation of the pressure signal of combustion chamber draft sensor 1, oxygen content sensor 10
Concentration signal, the temperature signal of outdoor temperature sensor 9 are concurrently accessed PLC control cabinet 2, by PLC
Switch board 2 sends control instruction according to the signal of input, is defeated by air-introduced machine converter 3, air blast respectively
Machine converter 5 and fire grate converter 8, control boiler or air stove runs.
Outdoor temperature sensor 9 monitors outdoor temperature continuously, and outer variations in temperature enters a certain temperature
Duan Shi, PLC control cabinet 2 controls to air-introduced machine converter 3 output order, and air-introduced machine converter 3 is pressed
