The controlling method based on the three lane tunneling aeration machine control system of PLC that realizes the invention described above main purpose is: press starting button, two of the worktable booster motors are according to I in each lane
A1→ I
A2→ II
A1→ II
A2→ III
A1→ III
A2Sequence interval Δ t start successively, in fact on the same stage two motors in the booster at interval 3 Δ t start, can realize the limited soft unlatching of booster air duct like this, prevent that the air duct interface from coming off, and avoids the generation of air leakage phenomena.After the normal operation of worktable, reserve position is in hot stand-by duty, if there is any one to break down and trip in each booster that worktable is controlled, as short circuit, overload, the phase failure etc., two motors of corresponding blower fan that reserve position is controlled can be according to setting time starting automatically at interval, and signal simultaneously gives the alarm.
In each portion of road bureau ventilator of controlling of operation platform, there is any one to break down and after the automatic trip, two motors of corresponding blower fan that reserve position is controlled can be according to setting time starting automatically at interval, this moment, so wherein one was tunneled the danger that the lane will face blowing-out as if the reserve position starting failure.For the continuity that guarantees that driving face ventilates, can manually control booster.At this moment, the PLC in the two cover control gear does not all participate in control, the control gear that the maintenance man must overhaul as early as possible and recover to break down, and after Awaiting Overhaul recovered, the control gear that in time will manually control operation switched in the control gear of having fixed.Behind normal the switching, the attendant must overhaul and recover to be in just now the control gear of manual operation as early as possible, makes it be in hot stand-by duty.
In three lane tunneling processes, if the gas density around the booster surpasses 0.5%, so all boosters must be out of service, and need discharge this moment to the gas in each tunnel, and the discharging program is decided according to the gas density in the tunnel.During firedamp drainage, can select the booster and the motor that will start arbitrarily, promptly a booster may only need a starting motor wherein.In this case, the attendant can select to need the motor of starting, can realize that the separate unit motor independently controls.
The continuity of booster air feed when considering three lanes driving, after certain control gear hinders tripping operation for some reason, reserve position puts into operation automatically, and the integrated control system that the attendant must overhaul as early as possible and recover to break down this moment is after maintenance finishes, in order to examine the maintenance effect, should carry out no-load test, at this moment, system's main circuit power is cut off, the used control power supply of centralized control system is taken from the insulating phase-change switch end of incoming cables, and each portion of road bureau ventilator that integrated control system is controlled does not move.After check finishes, should place hot stand-by duty by the integrated control system that maintenance is good.
