Embodiment
The utility model mainly comprises main control cabinet 20 and blower fan control box 8, blower fan control box 8 external many table glass steel explosion-proof roof fans 1, Electric air valve 2, temperature transducer 3, differential pressure transmitter 4.
The panel of blower fan control box 8 is provided with terrain diverter switch 6, respectively temperature digital Displaying Meter 5 and the pressure reduction read out instrument 7 that links to each other with differential pressure transmitter 4 with temperature transducer 3.Be provided with contactor assembly 21 in the blower fan control box 8, relay assembly 22, I/O wiring terminal 23.
The panel of main control cabinet 20 is provided with touch screen 14, power supply indicator 15, and power switch 16, emergency stop push button 17, alarm signal is changeed lamp 10, warning noise elimination answer button 18, warning buzzer 12, ammeter 11, voltmeter 13, print windows 19.The cabinet of main control cabinet 20 is provided with draught fan 9.Be provided with switch power 25 in the main control cabinet 20, PLC programmable controller 24, input relay group 26, output relay group 30, air-break switch 31 is pressed tentaculum 32, isolating transformer 33, printer 28, lead-in clamp 27, output wiring terminal 29.
" SF1 type windward " ventilation plant intelligent control application program is installed in the PLC programmable controller 24, can realize temperature, pressure, solar term, time, start-up routine, working time, the isoparametric setting of operation quantity, demonstration, printing and control, fault are shown and warning by the operation of touch screen 14, printer 28 etc.
Specific implementation process is: 1. summer:
---touch screen 14 shows " summer " page or leaf automatically by the date of setting.
---all air-valves 2 are in opening state automatically;
---all blower fans 1 just are in and change, exhausting exhaust operating mode;
When room temperature is 40 ℃, the signal value of temperature transducer 3 outputs reaches the setting value on the touch screen 14, PLC programmable controller 24 starts corresponding blower fan 1 automatically by the control program of having set, the startup of every typhoon machine is spaced apart 20 seconds (can set), if fan trouble can't start, system can report to the police automatically, and shows the numbering of fault blower fan on touch screen 21, and eliminates the noise by warning noise elimination answer button 18.
When room temperature was 37 ℃, the signal value of temperature transducer 3 outputs reached the setting value on the touch screen 14, and PLC programmable controller 24 cuts out corresponding blower fan 1 automatically by the control program of having set.
In the actual moving process, can be by usage quantity grouping operation, to carrying out reasonable distribution the working time of each blower fan.2. transition season:
---touch screen 14 shows " transition season " page or leaf automatically by the date of setting;
---all air-valves 2 still are in opening state;
---all blower fans 1 still just are in and change, exhausting exhaust operating mode;
Because transition season, room temperature reduces, and need not blower fan and all moves, and only needs a small amount of fan operation, at this moment the operation number of PLC programmable controller 24 automatic switchover blower fans.The general standby fan that starts earlier turn-offs the operation blower fan again.3. winter:
---touch screen 14 shows " winter " page or leaf automatically by the date of setting;
---all air-valves 2 are in closed condition automatically;
---all blower fans 1 are in counter-rotating air-supply operating mode automatically;
---must open air-valve 2 earlier when starting blower fan and restart blower fan 1;
---must close blower fan 1 when closing blower fan earlier and close air-valve 2 again;
When outdoor temperature was lower than 0 ℃, system's automatic setting entered winter condition.When indoor malleation is lower than 5Pa, the pressure mean values signal of differential pressure transmitter 4 outputs of ± 0.00mm layer is delivered to the malleation value lower limit that touch screen 14 is set, 24 of PLC programmable controllers increase by the Automatic Program of having set and start blower fan 1, the startup of every typhoon machine is spaced apart 20 seconds (can set), when blower fan 1 is increased to 3 (can set) when reaching requirements not yet, then system alarm checks whether door and window closes.
When indoor malleation value reached 30Pa, the pressure mean values signal of the differential pressure transmitter of ± 0.00mm layer 4 outputs reached the malleation value lower limit that touch screen 14 is set, and 24 of PLC programmable controllers reduce by the Automatic Program of establishing output and turn-off blower fan 1.
In the time of (can setting) fan operation more than 2, also can be by organizing into groups program control operation working time, to carrying out reasonable distribution the working time of each blower fan.When general blower fan switches, start standby fan earlier, cut off the operation blower fan again.Fan trouble can't start, can automatic sound-light alarm, and on touch screen 14, show the numbering of fault blower fan, eliminate the noise by warning noise elimination answer button 18.
Blower fan control box 8 of the present utility model is provided with automatic/hand diverter switch 6, when switching to manual position, can manually start, stop blower fan 1 and air-valve 2 at terrain.Temperature digital Displaying Meter 5 and pressure on the number Displaying Meter 7 also are housed on the blower fan control box 8, are used for showing the temperature and the air pressure of terrain.
