Brief description of the drawings
Fig. 1 is a kind of structural representation of modified Control System of Tunnel Ventilation of the present invention.
Embodiment
A kind of modified Control System of Tunnel Ventilation, including Ventilation Control computer and with Ventilation Control computer distinguish
The visibility and CO concentration detectors of connection, anemoclinograph, axial flow blower controller and jet blower controller composition；Axle
Flow fan controller is connected with axial flow blower, and jet blower controller is connected with jet blower.
Wherein, described visibility and CO concentration detectors are CO detectors and VI detectors；Visibility and CO concentration
Detector automatically determines the synthesis visibility under lighting in tunnel, automatically determines CO concentration distributions in tunnel, visibility and
CO concentration detectors are located in main tunnel, and 3 are set in each ventilation section；Set spacing according to ventilation segment length difference without
Together；Per Yin, last, which sets, does in the range of away from 100~150m of air shaft air exhaust passage mouth or tunnel exit.
Axial flow blower is arranged in the underground Ventilator Room of vertical shaft at tunnel three.Jet blower homogenizing step in tunnel,
Every about 350m/ platforms.
Ventilated control system mainly detects to the ventilation condition in tunnel and the running status of blower fan, possesses data and adopts
Collect processing function, air-blower control function and the writing function of operating condition feedback function and full detail.And can be according to tunnel
Interior wind speed, wind direction, CO, VI data message and blower fan turning provides corresponding control program, unlatching to tunnel blower,
Stop, rotating working condition is controlled.System possesses the Ventilation Control function under the conditions of normal condition and fire bar occurs
Ventilation Control function under part.
This programme uses subregion unit control mode, controls the operation of ventilating system.In monitoring system of divulging information, according to
The actual specific feature such as garage direction, geographical feature and construction characteristic in tunnel, it is contemplated that the factor such as tunnel fire hazard situation, will
Tunnel ventilation situation is divided into region and carries out overall control.Under automatic control mode, ventilating system is calculated by tunnel operation control center
Machine and live Ventilation Control PLC are automatically controlled.By CO, the trap signal of VI sensors measurement, measure place positioning and
Ventilating system is maintained at by control algolithm preset in the range of.Under normal circumstances, the control sequence of blower fan depends on blower fan
Working time, most short blower fan of such working time will be placed in the position preferentially started.
Wind speed and direction detects real-time elm and surveys interior wind direction, the air speed data parallel to tunnel wall of tunnel incident, to judge to divulge information
System operation situation.Axial flow blower detects：Axial flow blower and its control device are the most important, most high of guarantee tunnel normal operation
Expensive equipment, it is arranged near air shaft in the Ventilator Room of underground.Underground Ventilator Room is away from tunnel face, cool, damp, air lemon
Dye is serious, and it is on duty for a long time to be not suitable for staff.To ensure that the peace of driver and passenger in tunnel is striven and comfortably, axial flow blower need to be
Continuously run under rugged environment, therefore, the operating condition of axial flow blower should be grasped in time, monitor the work ginseng of its critical piece
Number (temperature rise of such as main motor).The timing of these parameters is passed to spout to control room and remotely monitored by well.Jet blower state is examined
Survey：Rotation stop, reversion and the stopped status of detection jet blower in real time, and the blower fan work time is recorded.Visibility and CO
Concentration detector, the detection of anemoclinograph working condition：Periodic detection visibility and CO concentration detectors, the work of anemoclinograph
Make state, alert during equipment fault.
