Embodiment
A kind of modified model Control System of Tunnel Ventilation, is made up of visibility and CO concentration detector, anemoclinograph, Ventilation Control computer, axial-flow blower controller, jet blower controller and axial-flow blower and jet blower.
Wherein, visibility and CO concentration detector measure the synthesis visibility in tunnel under lighting automatically, and automatically measure CO CONCENTRATION DISTRIBUTION in tunnel, visibility and CO concentration detector are located in main tunnel, arrange 3 in each ventilation section.Setting space is different according to ventilation section length difference; Every Yin last establish dry apart within the scope of air shaft ventilation channel mouth or tunnel exit 100 ~ 150m.Wind speed and direction detector detects wind direction, the air speed data of parallel dry tunnel wall in tunnel in real time, in order to judge ventilation system operation conditions, wind speed and direction detector is located in Chu Zhu tunnel, air shaft gateway, within the scope of tunnel exit 100 ~ 150m and vertical shaft and tunnel got in touch with in air channel.Axial-flow blower is arranged in the underground wind machine room of tunnel three place vertical shaft.Jet blower homogenizing step is in tunnel, and interval is about 350m/ platform.
Ventilated control system mainly detects the ventilation condition in tunnel and the running state of blower fan, possesses the record function of data acquisition process function, air-blower control function and operating condition feedback function and full detail.And corresponding control program can be provided according to the data information of the wind speed in tunnel, wind direction, CO, VI and blower fan turning, to the unlatching of tunnel blower, stopping, clockwise and anticlockwise
Working state controls.System possesses the Ventilation Control function under normal condition condition and the Ventilation Control function under breaking out of fire condition.
This programme adopts zoning unit control mode, controls the operation of ventilation system.In ventilation supervisory system, the feature actual concrete according to garage direction, geographical feature and construction characteristic in tunnel etc., considers and tunnel ventilation situation is divided into the factors such as tunnel fire hazard situation region and carries out overall control.Under automatic control mode, ventilation system is controlled automatically by tunnel operation control center computer and on-the-spot Ventilation Control PLC.Ventilation system remained in the scope preset by the trap signal of CO, VI sensor measurement, the location measuring place and control algorithm.Under normal circumstances, the blower fan operating time is depended in the control sequence of blower fan, and the shortest blower fan of such operating time will be placed in preferential position of starting.
Wind speed and direction detect real-time elm survey tunnel meet with in be parallel to wind direction, the air speed data of tunnel wall, in order to judge ventilation system operation conditions.Axial-flow blower detects: axial-flow blower and control apparatus thereof are most important, the most expensive equipment ensureing tunnel normal operation, to be arranged near air shaft in the wind machine room of underground.Underground wind machine room is away from tunnel face, and cool, damp, air lemon dye is serious, is not suitable for staff on duty for a long time.For ensureing that the peace of driver and passenger in tunnel is striven with comfortable, axial-flow blower need operate continuously under rugged environment, therefore, should grasp the operating conditions of axial-flow blower in time, monitors the running parameter (temperature rise etc. as mair motor) of its critical piece.These parameter timings pass and spout to control room by well. carry out remote monitoring.Jet blower state-detection: detect the spline of jet blower, reversion and outage state in real time, and the blower fan operating time is carried out record.Visibility and CO concentration detector, anemoclinograph working state detects: the working state of periodic detection visibility and CO concentration detector, anemoclinograph, sends warning message during equipment failure.
