Embodiment：
The present invention in order to eliminate the security risk of system blowing-out during existing ventilation blower " zero wind pressure, zero air quantity switching ",
" Mine Ventilator air pressure air flow balance switching intelligence control system " pattern is innovatively proposed, and is ensured in handoff procedure
Air pressure air flow balances, and the characteristics of pattern is most prominent in the effective supply of the ventilation quantity in handoff procedure is realized and wind pressure, is
Mining ventilation and safety provides safeguard.In order to realize air balance switching, it is necessary to be pressed off by PLC control system to wind turbine, air door, height
Close cabinet, high voltage converter intelligent comprehensive coordinates control, carries out surveillance monitor by wind turbine on-line monitoring system.With reference to Fig. 2 and Fig. 3
Sketch its course of work and principle：
1st, manual switching mode：Driver only needs to rotate " PAU+FCU system " knob, and intelligence control system can be completed wind turbine and cut
The overall process changed (by taking the PAU+FCU system in 1# air passages to the wind turbine in 2# air passages as an example).
During 1. the wind turbine for setting 1# air passages runs well, at this point, the vertical flashboard valve ZFM1 of the related air door in 1# air passages, vertical
Linked network air door LFM1 is in opening, and horizontal air door SFM1 is closed；The related air door in 2# air passages is completely in pass
Closed state.Switching starts, and first opens two wind turbines in 2# air passages, closing is completely in due to the corresponding part of appliance in 2# air passages
State is equivalent to frequency converter No Load Start, reduces and starts the time, ensures to start success rate；Under manual switching pattern, rotate
" PAU+FCU system " knob, system automatically turn on the horizontal air door SFM2 in 2# air passages, at the same start high voltage converter GYBP3 and
GYBP4 and two wind turbine realizes pre- stand-by heat before start.At this point, PLC control system (4) and wind turbine on-line monitoring system (5) inspection
Whether two wind turbine operating conditions for surveying 2# air passages are normal；
2. after wind turbine operating condition and normal air passage index, system automatically opens vertical linked network air door LFM2 and vertical lock
Plate valve door ZFM2, close horizontal air door SFM2 (SFM2 is 1. opened from step 2. to open LFM2 and ZFM2 to step and close SFM2,
This process only needs about 13 seconds or so time)；Horizontal air door SFM1 is opened simultaneously, close vertical linked network air door LFM1 and is stood
Formula flashboard valve ZFM1 makes two, the 1# air passages wind turbine of former operating status be transitioned into dry run state, the wind turbine transition in 2# air passages
To normal band net operating condition.
In this process, any air door speed of change and the change of state between 0-90 ° is all monitored in real time
The influence of air quantity and negative pressure parameter inside air passage, in order to remain unchanged total blast volume wind pressure, needs to control during switching
The throttle opening size of two Fans is made, by 1# air door of air duct standard-sized sheets, opens a part of air door to 1# air passages, 2# opens a part in air passage
Air door stops to 1# air passages, and air door is closed, and 2# air passages are opened full trrottle transition and completed.It will thus be seen that the mistake of air passage switching
There are two sets of wind turbines in Cheng Zhonghui while operation and air passage open simultaneously (but opening angle needed according to control controllable),
The system is exactly to achieve the purpose that balance switching using the control in real time of this feature.
3. in handoff procedure, air channel volume, negative pressure parameter are detected in real time, on the premise of its basicly stable, balance is ensured
The opening and closing of each air door is controlled to coordinate the time, realizes balance transition.Specially：Monitoring 1# air passages, 2# air passages and underworkings in real time
The negative pressure of air outlet, wind speed and and then calculate the air quantity in 1# air passages, 2# air passages and underworkings air outlet, control it is substantially former
It is then the air quantity for progressively reducing 1# air passages, synchronous equal amount increases the air quantity in 2# air passages, ensures the air quantity of underworkings air outlet not
Become.If the air pressure air flow of underworkings air outlet decreases in handoff procedure, the unlatching of ZFM2 and LFM2 is controlled at this time
Speed is faster than the closing velocity of ZFM1 and LFM1, and the closing velocity of SFM2 is controlled to be faster than the opening speed of SFM1；If switching
The air pressure air flow of underworkings air outlet increases in the process, at this time control ZFM2 and LFM2 opening speed be slower than ZFM1 and
The closing velocity of LFM1 controls the closing velocity of SFM2 to be slower than the opening speed of SFM1；This process is PLC according to air quantity and bears
Pressure automatically adjusts the process of two air door of air duct.
4. after wind turbine on-line monitoring system 5 detects that the wind turbine linked network in 2# air passages works well, the 1# for former operating of stopping
The wind turbine in air passage, closes horizontal air door SFM1, and handoff procedure is completed.
2nd, automatic switching mode：System detectio is in the operating status and parameter with wind turbine, when finding its failure, intelligence control
System processed is automatically performed the overall process of PAU+FCU system, while implements to alarm, and fan trouble data is recorded, in order to malfunction elimination.
The action process of each equipment and " manual mode " are similar, are simply to be automatically performed switching.
3rd, automatic switching mode and manual switching mode difference lies in：Automatic switching mode is for air passage equipment
Control system is automatically performed the overall processes such as fault identification, switching confirmation, process control and switching result during failure；Manual switching
Mode is the process for being switched based on artificial wish and being implemented, and switching must be first completed by people and confirmed, cut afterwards by control system completion
It changes.And no matter common ground is automatic switching mode or manual switching mode, once into changeover program, what is entirely switched is excessively program-controlled
System (opening and closing of start-stop, air door including wind turbine and speed) is all completed by PLC control system.
The above described is only a preferred embodiment of the present invention, not doing limitation in any form to the present invention, appoint
What those skilled in the art, without departing from the scope of the present invention, is made a little using above-mentioned technology contents
It changes or the embodiment of modification, in the range of still falling within technical solution of the present invention.
