Definitions

  • the present invention relates to a controller for tunnel ventilating systems for ventilating a traffic tunnel through which transports such as automobiles that discharge exhaust gas run and, more specifically, to a controller for tunnel ventilating systems, capable of controlling tunnel ventilating systems for stable and economical operation by controlling both the flow speed and flow rate of the air in a traffic tunnel.
  • Automobile traffic tunnels and railway tunnels for trains with a diesel locomotive or a steam locomotive need to be ventilated continuously to prevent the danger of the tunnels being filled with the exhaust gas discharged by automobiles or the locomotives. Accordingly, such tunnels are equipped with ventilating holes, exhaust blowers and supply blowers.
  • Fig. l. Figs. 2A, 2B, 3A and 3B are pollution distribution characteristic diagrams showing the condition of air pollution within a tunnel equipped with such a tunnel ventilating system.
  • a vertical ventilating shaft l is formed substantially at the middle of a tunnel 2 and an exhaust blower 3 for discharging polluted air from the tunnel 2 is provided in the ventilating shaft 2. Jet fans 4a and 4b for driving the polluted air toward the ventilating shaft l is attached to the ceiling of the tunnel 2.
  • a controller l0 for controlling the ventilating system comprising the exhaust blower 3 and the jet fans 4a and 4b controls the ventilating system on the basis of data obtained by sensors 6 and 7 for detecting the degree of air pollution, wind flow direction and wind speed within the tunnel, including visibility index (VI) meters, attached to the ceiling of the tunnel 2 on the opposite sides of the opening la of the ventilating shaft l, respectively.
  • the controller l0 comprises a program notch control unit ll which determines the mode of operation of the exhaust blower 3 and the jet fans 4a and 4b, such as the number and rotating speed of the exhaust blower 3 and the jet fans 4a and 4b, according to a program notch stored in a memory device, not shown; a manual notch control unit l2 which determines the mode of operation of the exhaust blower 3 and the jet fans 4a and 4b, such as the number and rotating speed of the exhaust blower 3 and the jet fans 4a and 4b, according to a notch given to the controller l0; an input data processing unit l3 which receives detection signals periodically from the sensors 6 and 7 and averages the detection signals; a software switching unit l4 which sets the data processing timing of the program notch control unit ll; operation mode correcting unit l5 which receives the output signal of the program notch control unit ll controlled by the switching unit l4, the output signal of the manual notch control unit l2 and the output signal of the input data processing unit
  • a manual notch given by external means to the manual notch control unit l2 is switched by a switching unit l7.
  • the control pattern determining unit l6 of the controller l0 is connected to the exhaust blower 3 and the jet fans 4a and 4b by a control circuit l8.
  • the controller l0 thus constituted for controlling the tunnel ventilating system measures the degree of pollution of the air within the tunnel 2 by means of the sensors 6 and 7, and then controls the exhaust blower 3 and the jet fans 4a and 4b on the basis of the measured data.
  • Measured degrees of pollution x and y in sections A and B between the portal 2a of the tunnel 2 and the opening la of the ventilating shaft l and between the portal 2b of the tunnel 2 and the opening la of the ventilating shaft l, respectively, as shown in Fig. 2A vary along characteristic curves shown in Fig. 2B.
  • the degree of pollution is highest in a region in the vicinity of the opening la of the ventilating shaft l as illustrated in Fig. 2B, and hence it is possible to control the ventilation of the tunnel 2 on the basis of the data x and y measured by the sensors 6 and 7.
  • the flow of the fresh air within the tunnel 2 is affected by the difference between the portals 2a and 2b of the tunnel 2 in atmospheric pressure, the number, direction and type of vehicles, such as automobiles or trains, which run through the tunnel 2. Therefore, it is difficult to maintain the distribution of degree of pollution in such character­istics as illustrated in Fig. 2B.
  • blow-through occurs in the tunnel 2, in which fresh air flows only in one direction from the portal 2a toward the portal 2b or from the portal 2b toward the portal 2a and the air within the tunnel 2 is scarcely ventilated through the ventilating shaft l.
  • the distribution of the degree of pollution assumes a characteristic as illustrated in Fig. 3A or 3B.
  • blank arrows indicates the direction of flow of fresh air within the tunnel 2.
  • the degree of pollution at the outlet portal 2a or 2b exceeds an allowable level indicated by a dotted line.
  • a controller for tunnel ventilating systems which detects the degree of pollution, the flow rate and flow speed of air within the tunnel and the pressure difference between the interior and exterior of the tunnel by various sensors for data acquisition disposed within the tunnel, controls the tunnel ventilating system by the flow speed control device of an arithmetic data processing unit on the basis of the data acquired by the sensors so that air flows from the opposite portals of the tunnel toward the ventilating shaft of the same always at an appropriate flow speed, determines the rate of ventilation by the flow speed control device of the arithmetic data processing unit so that the degree of pollution of the air within the tunnel will not exceed a predetermined limit of pollution and the tunnel is ventilated at the least necessary rate of ventilation, and controls the operation of the tunnel ventilating system comprising jet fans, an exhaust blower or blowers, and a dust collector or collectors on the basis of the manipulated values determined by the arithmetic data processing unit.
  • FIG. 4 the constitution and arrangement of a ventilating shaft l, an inner opening la of the ventilating shaft l, a tunnel 2, portals 2a and 2b, and an exhaust blower 3 are the same as those of the conventional tunnel ventilating system and the tunnel shown in Fig. l, hence the description thereof will be omitted to avoid duplication.
  • a tunnel ventilating system l9 comprises the exhaust blower 3 and jet fans 4 and 5.
  • the jet fans 4 and 5 are disposed within the tunnel 2 on opposite sides of the opening la of the ventilating shaft l, respectively, to supply fresh air from the portals 2a and 2b toward the opening la, respectively.
  • a detecting system 20 for detecting various physical values is provided within the tunnel 2.
  • the detecting system 20 comprises air pollution sensors 2l and 22, such as visibility index meters (hereinafter designated as “VI meters”) or carbon monoxide concentration detecting meters (hereinafter designated as “CO meters”), anemometers 23 and 24 attached to the ceiling of the tunnel 2 on opposite sides of the opening la to detect the respective flow speeds of air flowing from the portal 2a toward the opening la and air flowing from the portal 2b toward the opening la, respectively, microbarometers 25a and 25b attached to the ceiling of the tunnel 2 near the portals 2a and 2b to measure the atmospheric pressure near the portals 2a and 2b, respectively; traffic volume detectors 26a and 26b disposed near the portals 2a and 2b, respectively, to detect the type, number and running speed of automobiles coming into the tunnel, and traffic volume detectors 27a and 27b disposed outside the tunnel at a fixed distance from the portals 2a and 2b, respectively, to detect the type, number and running speed of automobiles running toward the tunnel 2 on approaches to the tunnel 2.
  • VI meters visibility index meters
  • CO meters carbon
  • the data acquired by the detectors of the detecting system 20 are operated and processed by a processing unit 30 comprising a basic logic unit 3l which calculates a long-term traffic volume estimate, a degree of pollution, a required ventilating rate and a flow rate allocation on the basis of data acquired by the traffic volume detectors 26a, 26b, 27a and 27b, a flow rate correcting unit 32 which corrects the flow rate on the basis of data acquired by the air pollution sensors 2l and 22 and the output signal of the basic logic unit 3l, and a flow speed control unit 33 which controls the flow speed of air within the tunnel 2 on the basis of wind speed data detected by the anemometers 23 and 24, atmospheric pressures near the portals 2a and 2b detected by the microbarometers 25a and 25b, a traffic volume detected by the traffic volume detectors 26a, 26b, 27a and 27b and the output signal of the basic logic unit 3l.
  • a processing unit 30 comprising a basic logic unit 3l which calculates a long-term traffic volume estimate, a degree
  • the exhaust blower 3 of the tunnel ventilating system l9 is controlled by a blower control circuit 34 according to the output signals of the flow rate correcting unit 32 of the processing unit 30.
  • the jet fans 4 and 5 of the tunnel ventilating system l9 are controlled by a jet fan control circuit 35 on the basis of the output signals of the flow speed control unit 33.
  • the basic logic unit 3l of the processing unit 30 executes a long-term traffic volume estimating task 4l to estimate a traffic volume at a time in the subsequent 30 to l20 min on the basis of various traffic volume data T D concerning automobiles passing through the tunnel 2, such as the time series data of the number of automobiles classified by type and the running speed of automobiles, detected by the traffic volume detectors 26a, 26b, 27a and 27b, and then the basic logic unit 3l executes a pollution level calculating task 42 to calculate a pollution level within the tunnel 2 under the estimated traffic volume. Then, the basic logic unit 3l executes a ventilation demand calculating task 43 to calculate a ventilation rate necessary to maintain the degree of pollution within the tunnel 2 below an allowable degree of pollution.
  • the exhaust blower 3 and the jet fans 4 and 5 of the ventilating system l9 are operated for a ventilation rate exceeding the ventilation demand calculated in the ventilation demand calculating task 43 to attain a control target.
  • the operation of the ventilating system l9 at an excessively high rate increases the power cost wastefully.
  • a flow rate allocation calculating task 44 is executed. After accomplishing the tasks 4l to 44, the basic logic unit 3l provides a reference wind speed S R , a reference ventilation rate R R , and a reference jet fan number N R .
  • the reference wind speed S R is wind speeds in the sections of the tunnel 2 on the opposite sides of the opening la, respectively, when the ventilating system l9 is operated in the operation pattern selected through the flow rate allocation calculating task 44.
  • the reference ventilation rate R R is an exhaust rate of the exhaust blower 3 when the ventilating system l9 is operated in the selected operation pattern.
  • the reference jet fan number N R is the number of jet fans to be operated among the jet fans 4 and 5 when the ventilating system l9 is operated in the selected operation pattern.
  • the tunnel ventilating operation is carried out on the basis of those reference values provided by the basic logic unit 3l.
  • the basic logic unit 3l is actuated every 30 to l20 min to update the reference values.
  • the flow rate correcting unit 32 of the processing unit 30 carries out the following functions. Traffic volume in the tunnel 2 is variable and does not remain constant for 30 to l20 minutes. Since the basic logic unit 3l is actuated every 30 to l20 minutes, the traffic volume data T D needs correction, and hence the reference values calculated by the basic logic unit 3l also need correction.
  • the flow rate control unit 32 executes a short-term traffic volume estimating task 45 on the basis of the time series data provided by the traffic volume detectors 26a, 26b, 27a and 27b to estimate a short-term traffic volume.
  • a traffic volume feed forward control task 46 is executed to calculate a correction by comparing the estimated short-term traffic volume and the estimated long-term traffic volume obtained through the long-term traffic volume estimating task 4l by the basic logic unit 3l.
  • An air pollution feedback control task 47 is executed to calculate an air pollution degree correction by comparing a measured air pollution degree P M and an air pollution degree target P T .
  • the air pollution degree feedback control operation is a VI feedback control operation based on a measured haze transmis­sivity and its reference value, or a CO feedback control operation based on a measured CO concentration and its reference value.
  • the flow rate correcting unit 32 adds the reference ventilation rate R R and corrections obtained through the traffic volume feed forward task 46 and the air pollution feedback control task 47 by means of an adder 48 to provide a final control value 50 of flow rate for the exhaust blower 3.
  • the flow rate control unit 32 is actuated every approximately l0 minutes, because excessively frequent change of the operating condition of the exhaust blower 3 having a large capacity affects adversely to the durability of the exhaust blower 3 and the variation of air pollution degree within the tunnel 2 in a time about one minute is insignificant.
  • the flow speed control unit 33 of the processing unit 30 carries out the following functions. Generated in the tunnel 2 are various forces affecting the movement of air within the tunnel 2, such as wind force generated by the running of vehicles (ventilating force generated by traffic), natural wind force attributable to the difference between the portals of the tunnel 2 in atmospheric pressure, pressure raising force resulting from the ventilating operation of the tunnel ventilating system l9, frictional resistance of the wall of the tunnel 2 against the flow of air, resistances at the portals causing a loss in wind force and other various forces.
  • various forces affecting the movement of air within the tunnel 2 such as wind force generated by the running of vehicles (ventilating force generated by traffic), natural wind force attributable to the difference between the portals of the tunnel 2 in atmospheric pressure, pressure raising force resulting from the ventilating operation of the tunnel ventilating system l9, frictional resistance of the wall of the tunnel 2 against the flow of air, resistances at the portals causing a loss in wind force and other various forces.
  • a pressure balance calculating task 5l is executed to calculate a pressure balancing value on the basis of the traffic volume data T D , a natural inflow rate R N and the reference wind speed S R . Then, a wind speed feedback control task 52 is executed to calculate a correction by comparing the reference wind speed V R and a measured wind speed S M measured by the anemometers 23 and 24.
  • the flow speed control unit 33 adds the reference jet fan number N R provided by the basic logic unit 3l, the pressure balancing value obtained through the tasks 5l and 52, and a feedback wind speed correction, and then provides a jet fan control value 55 for controlling the number of the jet fans to be operated among the jet fans 4 and 5, and the rotating speed of the jet fans.
  • the calculating operation of the flow speed control unit 33 needs to be executed at an interval smaller than those of operation of the basic logic unit 3l and the wind speed correcting unit 32, because, when an automobile runs through the tunnel 2, for example, from the portal 2b toward the portal 2a (Fig. 4), the automobile passes through the section A in L1/V sec and the section B in L2/V sec, where L1 (m) is the distance between the portal 2a and the opening la of the ventilating shaft l, L2 (m) is the distance between the portal 2b and the opening la of the ventilating shaft l, and V (m/sec) is the running speed of the automobile.
  • the wind speed correcting unit 32 executes the traffic volume feed forward control task 46 and the air pollution degree feedback control task 47 to obtain two corrections.
  • a control value 50 for controlling the exhaust blower 3 may be obtained on the basis of one or the other of the two corrections.
  • the flow rate correcting unit 32 may be omitted and the processing unit 30 may comprise only the basic logic unit 3l and the wind speed control unit 33.
  • the first embodiment of the present invention has been described as applied to the tunnel ventilating system l9 comprising the exhaust blower 3 and the jet fans 4 and 5, the application of the present invention is not limited thereto, but may be applied, in a second embodiment as illustrated in Fig. 6, to a tunnel ventilating system 59 comprising an exhaust blower 3, jet fans 4 and 5, and electric dust collectors 6l and 62 for collecting dust from the air within the tunnel.
  • the controller may include an exhaust and dust collection control circuit 64, and an electric dust collector control unit 60 for controlling the operation of the electric dust collectors on the basis of a flow rate correction value.
  • the control value 50 for controlling the exhaust blower 3 is used as a controlled value for controlling the exhaust blower 3 and the dust collectors 6l and 62.
  • the controller for tunnel ventilating systems controls the tunnel ventilating system to regulate the flow speed and flow rate of air within the tunnel on the basis of control values obtained by operating and processing information detected by detectors for detecting various physical values representing the degree of air pollution within the tunnel, and thereby the ventilating system is controlled for stable, economical ventilating operation, in which air flows always from both the portals of the tunnel toward the ventilating shaft.
