Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment;
Fig. 1 is a structured flowchart of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with embodiment, further set forth the present invention.
Referring to Fig. 1; The present invention provides a kind of FFU fan filter unit control system; It comprises regional host computer 1, router two, repeater 3, fan driver 4 and FFU fan filter unit 5; Each fan driver 4 can be controlled a FFU fan filter unit 5 at least, every a plurality of fan drivers 4 of repeater 3 may command, and a plurality of repeaters 3 of each regional host computer 1 control; A plurality of said repeaters 3 are connected with regional host computer 1 through a router two, through connecting layer by layer and controlling, are convenient to line maintenance and monitoring, have guaranteed the normal operation of FFU fan filter unit.
What deserves to be mentioned is that fan driver 4 is provided with power supply/line tutorial light, fault indicating lamp, wind speed tutorial light, can selects to set and close FFU fan filter unit or FFU fan filter unit is dropped to the DI alarm input end of minimum wind speed and the rotation speed of fan gear key of control FFU fan filter unit wind speed.This fan driver also is provided with IP address function of reset key; Voltage is AC220V during its full-speed operation; Whenever the 10V that successively decreases is one section wind speed, and ten sections wind speed controls altogether send the electricity back according to state (power supply, wind speed) running before shutting down last time; On it and have motor overload protection (8A)/no-load protection and postpone the overload of prevention immediate current with start.
In the present embodiment, the input of fan driver 4:
Supply voltage: AC 100～240 single-phase 50/60Hz.
Electrical source consumption: in 5 watts.
Tutorial light: power supply/online, fault, wind speed.
Button: Switching power and wind speed.
Output voltage: maximum voltage 220V, the 10V that whenever successively decreases are one section wind speed, altogether ten sections wind speed controls.
One typhoon machine driver can drive 1 → 5 FFU simultaneously.
The communication specification:
