Description
Technical field
The utility model relates to a kind of control system of blower fan filtering unit.
Background technique
FFU is an english abbreviation, and full name is Fan Filter Units, and the Chinese meaning is " blower fan filtering unit ".It exactly is a kind of self-powered, modular terminal blast device with filter efficacy.It is main that FFU mainly adopts the single phase alternating current Induction Motor Control, and mode of speed regulation has: many grades of speed governing of electron plate capacitance decompression, controllable silicon stepless speed regulation, all there is deficiency in various degree in this dual mode.
1. many grades of speed governing of electron plate capacitance decompression
Many grades of speed governing of electron plate capacitance decompression realize that one drags many control modes, can control more than 20 FFU at most, if FFU quantity is more, control is difficulty comparatively, and use is inconvenient, the staff to realize switching on and shutting down, and can only realize regional speed governing, can not the separate unit speed governing.If power of fan is bigger than normal, the electron plate output voltage can reduce, and has a strong impact on the FFU discharge quantity of fan.
2. controllable silicon stepless speed regulation
Controllable silicon stepless speed regulation realizes that by controllable silicon the utilization thyristor speed control can make motor produce noise, if many FFU move at clean room, the noise that is produced it is to be difficult to accept.And cut meeting generation harmonic wave, electronic apparatus is produced disturb.
The model utility content
The purpose of this utility model is, proposes a kind of FFU centralized monitoring system, solves the deficiencies in the prior art.
The technical solution adopted in the utility model is as follows:
The FFU centralized monitoring system comprises computer, main control system, control extension set and FFU unit controls module; FFU unit controls module comprises governor circuit, address setting unit, current detection circuit, output feeder loop, A/D conversion circuit and gear switch circuit, and address setting unit, current detection circuit, output feeder loop, A/D conversion unit and gear switch circuit all are electrically connected with governor circuit.
Preferably, described main control system comprises manual control circuit, digital display circuit and warning circuit.
Preferably, computer, main control system, control extension set and FFU unit controls module are equipped with the RS485 communication interface.
The beneficial effects of the utility model are, the FFU centralized monitoring system can link up thousands of FFU and monitor by the FFU monitoring host computer, and can be with data upload to computer, by the convenient functions such as the start and stop of blower fan subregion, malfunction alarm, historical record that realize of computer system.

Embodiment
As preferred embodiment, as shown in Figure 2, the FFU centralized monitoring system comprises with lower unit: computer 1, main control system 2,485 control extension sets 3, FFU control unit module 4, adopt the RS485 communication interface to carry out communication between each parts.
Manual control circuit is realized FFU start and stop, speed governing, and parameter and inquiry FFU state are set.
Digital display circuit utilizes nixie tube to show current FFU gear, element number, current values.
Warning circuit, main control system has buzzer, by single-chip microcomputer the current value that FFU detects is compared with setting current value, when the FFU current value surpasses the setting current value, triggers warning circuit, and buzzer is just reported to the police.
485 control extension sets 3 are the relay station of main control system 1 and FFU control unit module 4, adopt RS485 bus bind mode with main control system 1 and 4 controls of FFU control unit, receive main control system information and transmit information by the AT64 chip to the FFU unit module, and FFU unit module feedback data information analyzed, handles, and be uploaded to main frame, reach each unit controls module under the control signal that the reception main frame sends.
It is that core processor is realized the control function that FFU control unit module 4 adopts single-chip microcomputer, directly carries out main control system and provides order.
FFU control unit module comprises: governor circuit, address setting unit, current detection circuit, output feeder loop, A/D change-over circuit, gear switch circuit.
The address setting unit carries out dial-up by toggle switch to the FFU address, guarantees that every FFU address is inequality.
Current detection circuit is carried out monitoring by compact board live current transformer to the FFU electric current
The output feeder loop the numerical value of detected FFU electric current, is sent to main control system by the RS485 communication.
The A/D change-over circuit converts current signal to digital value and uploads to main frame again.
The gear switch circuit carries miniature relay by plate, carries out gear switch, is divided into 5 gears, utilizes five gears of extraction transformer to realize that different voltages switch, and FFU is carried out speed governing, does not produce extra noise.
The framework of FFU centralized monitoring system as shown in Figure 1, a computer can connect a plurality of main control systems, each main control system all is connected with a control extension set, each control extension set can connect many group FFU control units, each control unit can connect a plurality of FFU again.
Native system has following advantages:
1. highly versatile, reliability height: by using the RS485 communication, computer is monitored to all FFU, and to FFU feasible region or separate unit speed governing and start and stop, every FFU is carried out current monitoring.
2. perfect in shape and function, intellectuality: according to the filter life cycle, automatically regulate wind-speed gear by FFU computer Centralized Monitoring software. By increasing the timing task, reach each regional FFU automatic speed regulation and shut-off function. As long as set the task date, the staff need not carry out any operation to system, just reaches Based Intelligent Control. And can inquire about each zone at the historical record of the enterprising line operate of system. Can on deposit regional FFU plane.
3. do not produce the extra heating of motor and noise.
4. control is convenient: system carries out speed governing to FFU, can also can speed governing on main control system in the computer speed governing, and when system did not dispose computer or computer and is in off-mode, the FFU main control system can the monitoring of complete independently whole system.
5. overload protection function: when blower fan transshipped, automatic remote was reported to the police.
