DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling a tunnel ventilation system provided to reduce soot in a road tunnel to a certain concentration or less.

[0002]

2. Description of the Related Art Generally, in a road tunnel, since the inside of the tunnel is contaminated by soot generated by a vehicle, a ventilator is provided in the tunnel to generate an air flow from one side of the tunnel to the other side, thereby producing soot. Is discharged outside the tunnel. As a ventilator, a jet fan that is provided at the top of the tunnel and simply generates air flow in one direction, a shaft blower that discharges air from the hole provided above the tunnel to the outside, generally installed adjacent to this shaft blower There is a vertical shaft blower that blows air into the tunnel through a hole provided above the tunnel, a dust collector that is provided on the side wall of the tunnel, and that captures soot with a filter provided inside while generating an air flow.

[0003] Since the amount of vehicles passing through the tunnel is not constant but varies depending on the day of the week and the time of day, the ventilation in such a tunnel is performed by always operating all the ventilators in the tunnel at an operation rate of 100%. Instead, it is reasonable to operate the ventilator in accordance with the amount of soot that is proportional to the traffic volume in the tunnel without wasting power. That is, it is desirable that the number of operating ventilators be controlled to the minimum number and the minimum ventilation air volume capable of suppressing the soot concentration in the tunnel within a predetermined range.

Therefore, conventionally, for example, the traffic volume of a vehicle is measured at the end of a tunnel, the traffic volume of the vehicle after a predetermined time has elapsed is estimated from the measured traffic volume, and the predicted traffic volume is set in advance. By multiplying the amount of soot emission per vehicle by multiplying the amount of soot emission by a predetermined time, the amount of soot emission after a lapse of a predetermined time is predicted, and the ventilation amount at the predetermined time is calculated accordingly, thereby controlling the ventilator. Was.

However, since this method does not consider the concentration distribution of soot in the tunnel, it is difficult to accurately predict the concentration of soot in the tunnel, and proper ventilation control cannot be expected. Therefore, Japanese Patent Application Laid-Open No. 7-23879
A method for predicting soot distribution based on a soot distribution model in a tunnel as disclosed in Japanese Patent Application Laid-Open Publication No. 9-1997 has been proposed.

In this method, first, a soot concentration meter provided at the exit of the tunnel and an anemometer provided in the tunnel are used to determine the amount of soot generated by all vehicles passing through the tunnel within a predetermined time period, and to measure the amount of soot generated by a ventilator or the like. The air volume is measured, and a smoke concentration distribution is generated by the smoke generated by all vehicles passing through the tunnel within a predetermined time in consideration of the movement of the smoke due to the air volume. Then, by superimposing these, a soot concentration distribution in the tunnel is generated. Subsequently, the amount of smoke generated by all vehicles in the control cycle is determined based on the smoke concentration distribution, and a traffic detector provided at a position (control cycle) × (average vehicle speed) in front of the tunnel entrance. Calculates the amount of smoke generated by one vehicle from the traffic amount counted in the previous control cycle and the amount of smoke generated by all vehicles. Then, from the traffic volume in the current control cycle and the current smoke distribution model, the amount of smoke generated by all vehicles passing through the tunnel in the current control cycle is predicted. Start the machine. In this method, since the air volume to be generated by the ventilator is calculated in consideration of the smoke distribution in the tunnel, the ventilation volume can be more appropriately controlled as compared with the former method.

[0007]

However, when the smoke concentration distribution in the tunnel is generated by the above method, the smoke concentration distribution generated over the entire length of the tunnel by the vehicle passing through the tunnel is superimposed. Since the distribution is generated, the generated smoke concentration distribution can be obtained only roughly. In addition, since it is assumed that the vehicle passes through the tunnel within a predetermined period, the measurement period becomes longer in the case of a long tunnel, and the control cycle becomes longer. Proper ventilation control cannot be achieved. Further, in the above method, the traffic volume predicted in the current control cycle is (control cycle) × from just before the tunnel entrance.
(Average vehicle speed) Measured by a traffic detector provided at a position just before the vehicle, the traffic volume inside the tunnel and the traffic volume just before the tunnel have considerably different speeds, and the predicted traffic volume and the actual traffic volume As a result of a large error from the amount, there is a high possibility that the predicted increase in the amount of smoke will be different from the actual increase.

In view of the above problems, the present invention can generate a more accurate soot concentration distribution, can be applied regardless of the length of a tunnel, and can more accurately determine the estimated amount of soot to obtain a more appropriate amount. It is an object of the present invention to provide a tunnel ventilation control device capable of performing efficient ventilation control.

[0009]

[0015]

Embodiments of the present invention will be described below with reference to the drawings. It should be noted that the tunnel ventilation control devices described in the respective embodiments can be appropriately combined. Embodiment 1 FIG. 1 shows a schematic configuration diagram of a tunnel ventilation system. As shown in the figure, the tunnel ventilation system includes a ventilator F provided with a jet fan or the like provided in a tunnel A, a speed detector 2 for detecting the speed of a vehicle passing through the tunnel A, The traffic volume that detects the number of vehicles coming and the type of vehicle
The vehicle type detecting unit 3 includes a control unit 1 that controls the ventilator F. Here, it is assumed that the tunnel A is a one-way street, and the ventilation direction of the ventilator F matches the traveling direction of the vehicle. Further, here, the entrance of the tunnel means the entrance of the airflow by the ventilator F, and the exit of the tunnel means the exit of the airflow.

The control unit 1 has a CPU 10 as shown in FIG.
1, RAM 102, ROM 103, A / D converter 10
4, constituted by the D / A conversion unit 105,
3 achieves the operation described below. The traffic / vehicle type detection unit 3 detects that the vehicle has passed by the current flowing when the vehicle passes through the coil embedded in the road, counts this, and determines the passing time by the time when the current flows. It is configured to detect whether the detected vehicle is a large vehicle or a small vehicle. Here, for convenience, the traffic volume / vehicle type detection unit 3 is referred to as a traffic volume detection unit 3a when detecting traffic volume, and a vehicle type detection unit 3b when detecting a vehicle type.

FIG. 3 shows a functional block diagram of a tunnel ventilation control device according to the present embodiment for controlling such a tunnel ventilation system. As shown in the figure, the tunnel ventilation control device includes a control unit 1A, a vehicle speed detection unit 2, a vehicle type detection unit 3b, and a wind speed detection unit 4. The control unit 1A further includes a vehicle position calculation unit 11, a smoke emission amount setting unit 12, a vehicle-specific smoke concentration distribution generation unit 13, a smoke concentration distribution generation unit 14, a predicted vehicle position calculation unit 15, a predicted vehicle-specific smoke concentration distribution generation unit. 16,
It comprises a predicted soot concentration distribution generation unit 17, a ventilation amount calculation unit 18, and a ventilator control unit 19.

The vehicle position calculating section 11 calculates the position of each vehicle from the vehicle speed of each vehicle detected by the vehicle speed detecting section 2 every predetermined measurement period. More specifically, the vehicle position calculation unit 11 records the speed and time of the vehicle every time the vehicle passes through the position of the vehicle speed detection unit 2, and based on this information, keeps the speed of the vehicle constant. As a predetermined measurement cycle,
Here, the position of each vehicle in the tunnel is calculated every minute. Here, the position of each vehicle is fixed, but a plurality of vehicle speed detection sensors are provided in the tunnel to measure the change in the speed of the vehicle, so that the position of the vehicle according to the change in the vehicle speed can be determined. It can also be calculated.

The soot emission setting unit 12 calculates a known equation from the vehicle speed calculated by the vehicle speed detection unit 2, the vehicle type calculated by the vehicle type detection unit 3b, and the gradient of the section where the vehicle travels during the measurement cycle. This is a part that calculates the soot emission amount of each vehicle by using the calculated values and sets it as the soot emission amount of the vehicle. Here,
Although different types of large vehicles and small vehicles are used as vehicle types, more specific types of vehicles are identified using an image recognition device or the like. Methods such as calculating the amount can also be adopted. In addition, the smoke emission amount setting unit 12 calculates the smoke emission amount of each vehicle. However, the smoke emission amount setting unit 12 uses the average smoke emission amount of the vehicle obtained experimentally as a fixed value. Can also.

The vehicle-specific soot concentration distribution generating unit 13 calculates the soot emission amount preset for each vehicle by the soot emission setting unit 12 and the position of each vehicle during each measurement cycle calculated by the vehicle position calculating unit 11. From the difference, the emission distribution of the soot discharged by each vehicle during the measurement cycle is generated as the soot concentration distribution for each vehicle. More specifically, for example, if the vehicle P advances from the entrance of the tunnel to the point a during a specific measurement cycle, and the set amount of soot emission is K1 (m ³ / m), the vehicle P Assuming that the smoke discharged during the measurement cycle of P remains in a width proportional to the amount of discharged smoke in the section where the vehicle has passed, the smoke distribution is as shown in FIG. Similarly, vehicle Q advances from point b1 to point b2,
Soot emission is K2 (m ³ / m), vehicle R is c2 from point c1
Point, soot emission is K3 (m ³ / m) and vehicle S is d
From point 1 to d2, smoke emission is K4 (m ³ / m)
In this case, the concentration distribution of the soot discharged by each vehicle is as shown in FIGS. 4 (b), (c) and (d).

The soot concentration distribution generator 14 generates the soot concentration distribution for each vehicle generated by the soot concentration distribution generator 13 for each vehicle, the wind speed in the tunnel A detected by the wind speed detector 4, From the generated smoke concentration distribution in the tunnel, a smoke concentration distribution in the tunnel is generated for each measurement cycle. Specifically, the per-vehicle soot concentration distribution generation unit 13 generates the per-vehicle soot concentration distribution as shown in FIGS. 4 (a), (b), (c), and (d), and the wind speed is m (m / min). It is assumed that the smoke concentration distribution in the tunnel before the measurement cycle is in a state as shown in FIG. Then, the soot concentration distribution generating unit 14 first superimposes the soot concentration distribution diagrams for each vehicle shown in FIGS. 4A, 4B, 4C, and 4D with the soot concentration distribution in the tunnel before one measurement cycle in FIG. . The result is as shown in FIG. Next, since the smoke concentration distribution is caused to flow by the wind, the measurement period is now 1 minute, so that the smoke concentration distribution moves downwind by m × 1 (m). As a result, the smoke concentration distribution is
The result is as shown in FIG.

The predicted vehicle position calculator 15 calculates the position of each vehicle after a predetermined control cycle has elapsed from the detected vehicle speed and the calculated position of each vehicle. Specifically, assuming that the control cycle is one minute similarly to the measurement cycle, the vehicle position calculation unit 1
The position of each vehicle after 1 minute is calculated from the position of each vehicle calculated by 1 and the speed of each vehicle stored in the vehicle position calculation unit 11. Note that the value calculated by the predicted vehicle position calculation unit 15 can be directly flown to the vehicle position calculation unit 11 after the next measurement cycle.

The predicted vehicle-specific soot concentration distribution generating unit 16 calculates the soot emission amount preset for each vehicle by the soot emission setting unit 12 and the soot concentration after the elapse of the control period which can be calculated by the predicted vehicle position calculating unit 15. Based on the movement amount of the position of the vehicle, the emission distribution of the soot discharged by each vehicle during the control cycle is generated as a predicted soot concentration distribution for each vehicle. Here, as for the vehicles P, Q, and R that form the soot concentration distribution as shown in FIGS. 4A, 4B, and 4C, the results are as shown in FIGS. 7A, 7B, and 7C. It is assumed that a predicted soot concentration distribution for each vehicle is generated. Since the vehicle S has already escaped from the tunnel, it is not considered here.

The predicted soot concentration distribution generating unit 17 calculates the soot concentration distribution generated by the soot concentration distribution generating unit 14 and the predicted soot concentration distribution generated by the predicted vehicle soot concentration distribution generating unit 16. A smoke concentration distribution after the control cycle period is generated as a predicted smoke concentration distribution. Here, the smoke concentration distribution shown in FIG. 6 and the smoke concentration distribution for each predicted vehicle shown in FIG. 7 are superimposed, and the smoke concentration distribution as shown in FIG. Generate as Note that the generated soot concentration distribution is a soot concentration distribution when the wind speed from the present time until the control cycle elapses is 0.

The ventilation amount calculating section 18 calculates the required ventilation amount during the control cycle from the predicted smoke concentration distribution generated by the predicted smoke concentration distribution generating section 17. Specifically, assuming that Ko in FIG. 8 is an allowable soot concentration and that the soot concentration in the tunnel is equal to or lower than the Ko, the soot concentration in the section from the exit of the tunnel to L (m) is Ko as shown in the figure. Is over. As described above, FIG. 8 shows the soot concentration distribution in the case where the air volume until the control cycle elapses is 0, so that by sending the wind from this state during the control cycle period, the air existing in this section is discharged. Good. That is, assuming that the sectional area of the tunnel is S, S × L (m ³ ) is the required amount of air to be discharged. Since the current control cycle is one minute, the required air volume is (S × L) / 1 (m ³ / min), that is, S × L (m ³ / min).
min) calculated as necessary.

In FIG. 8, there is a portion other than the section from the outlet to L (m), which exceeds the allowable soot concentration Ko.
It is assumed that the air in the section where the portion exceeding the area is continuous is exhausted. This is because the ventilator sends out the smoke toward the exit of the tunnel, so that the smoke concentration is generally higher at the exit of the tunnel, and it is sufficient to discharge a continuous high smoke concentration portion from the exit. However, it goes without saying that it may be possible to discharge a portion where the smoke concentration suddenly increases near the middle of the tunnel.

The ventilator control unit 19 controls the ventilator F according to the ventilation volume calculated by the ventilation volume calculation unit 18. Specifically, the number of ventilators F necessary to realize the above-mentioned air volume and the air volume of each ventilator F are determined, and the ventilators F are operated uniformly for the control period in accordance with the determined number. The operation of the tunnel ventilation control device having the above configuration will be described below. FIG. 9 is a flowchart showing the operation of the tunnel ventilation control device during one control cycle. When the ventilation amount is calculated in the previous control cycle and the operation of the ventilator is started, the process proceeds to the next control cycle. First, the vehicle speed detection unit 2 detects the vehicle speed of a vehicle entering the tunnel, and the vehicle position calculation unit 11 records the detected time and vehicle speed. This is performed during the above-described measurement cycle (S101, S10
2).

When the measurement cycle elapses, the vehicle position calculating section 11
Calculates the current position of each vehicle from the recorded vehicle speed and the time at which the vehicle passed the vehicle speed detection unit 2 (S103). Note that the vehicle speed and the time at which the vehicle passed the vehicle speed detection unit 2 are those recorded in the previous measurement cycle. Then, the soot concentration distribution generation unit 1 for each vehicle
3 is based on the movement amount of each vehicle derived from the difference between the position of each vehicle in the previous measurement cycle and the current position of each vehicle, and the smoke emission amount of each vehicle set by the smoke emission amount setting unit 12. A soot concentration distribution is generated for each vehicle for each vehicle (S104).

Next, the wind speed in the tunnel is detected by the wind speed detecting section 4 (S104), and the soot concentration distribution generating section 14 calculates the soot concentration, the soot concentration distribution for each vehicle, and the soot concentration distribution in the previous measurement cycle. Then, the current soot concentration distribution is generated (S105). The operations from S101 to S106 are repeated until the control cycle elapses (S107).
However, in this case, since both the measurement cycle and the control cycle are set to one minute, when the soot concentration distribution is generated by one measurement, the operation shifts to the next operation.

When the control cycle elapses, the predicted vehicle position calculator 15 calculates the position of each vehicle after the control cycle elapses based on the data of the vehicle position calculator 11 (S108), and generates a soot concentration distribution for each predicted vehicle. The section 16 controls the amount of movement of each vehicle derived from this position after the control cycle has elapsed and the amount of soot emission setting section 1
Then, a predicted soot concentration distribution for each vehicle, which is a soot concentration distribution generated by each vehicle after the control cycle elapses, is generated from the soot emission amount of each vehicle set by 2 (S109).

Then, the predicted soot concentration distribution generating section 17
Generates a predicted soot concentration distribution which is a soot concentration distribution after a control period when the wind speed in the control cycle is 0 from the predicted soot concentration distribution for each vehicle and the current soot concentration distribution (S110). . Then, the ventilation amount calculation unit 18 calculates the ventilation amount required for the next control period from the predicted soot concentration distribution (S111), and the ventilation device control unit 19 calculates the number of ventilation devices according to the ventilation amount. F is operated throughout the current control period (S112). With the above operation, a portion exceeding the allowable soot concentration can be discharged from the tunnel by the ventilation of the ventilator F during the current control period.

In the above example, the predicted soot concentration distribution generated by the predicted soot concentration distribution generator 17 is, in principle, discharged from the exit in the section where the portion where the soot concentration exceeds the allowable soot concentration Ko is continuous. In this case, for example, as shown in FIG. 10, the predicted soot concentration distribution has a concave portion in a very short section l, and this portion does not exceed the allowable soot concentration Ko. In the case where the long section L includes the allowable soot concentration Ko, it is appropriate to consider that there is no concave portion.

Therefore, in the present embodiment, if the estimated soot concentration distribution has a recess having a width equal to or less than a predetermined width, the ventilation amount calculating section 18 calculates the ventilation amount assuming that there is no such recess. I have. Here, the predetermined width is a value obtained by dividing the air volume that can be blown by one of the ventilators F during the control cycle by the cross-sectional area of the tunnel. That is, here, the air volume is usually adjusted by the number of operating ventilators F, and since the air volume can be adjusted only in steps, the air volume that can be discharged during the control cycle, that is, the distance to the point including the air that is discharged from the tunnel exit is It can only be adjusted in steps. Therefore, it is considered that the part below this step width cannot be adjusted. But this width is
It can be determined for various other reasons, for example, if it is required that the smoke concentration be strictly below the allowable concentration, this width increases, and vice versa. You may.

In the above embodiment, the predicted soot concentration distribution generating section 17 generates a predicted soot distribution when the wind speed during the control cycle is 0, and the ventilation amount calculating section 18 determines the control cycle based on this. It calculates the ventilation volume inside. However, in practice, even if the number of operating ventilators is zero in the tunnel, the wind caused by the running of the vehicle,
The soot concentration distribution shifts due to the natural wind.

Therefore, as shown in FIG. 11, for example, an underground airflow detecting unit 5A for detecting a parameter for obtaining the airflow of the underground air is provided, and the control unit 1 is provided with a control cycle period based on the detected parameter variation. A predicted airflow calculating means for calculating the airflow due to the underground wind as the predicted airflow may be provided. In this case, the predicted soot concentration distribution generation unit 17 generates the predicted soot concentration distribution in consideration of the predicted airflow due to the downhole wind.

The underground airflow detection unit 5A includes a vehicle speed detection unit 2, a vehicle type detection unit 3b, and a natural airflow detection unit 5 for detecting natural wind. The natural airflow detection unit 5 detects the air pressure and the air temperature on the entrance side and the exit side of the tunnel, and calculates the difference between them. If the difference between the air pressure and the air temperature is known, the natural wind volume can be calculated. . Note that this natural airflow detection unit 5
May detect the wind speed at the pilot pit of the tunnel to obtain the natural wind volume.

Based on the detection results of the vehicle speed detecting unit 2 and the vehicle type detecting unit 3b, the predicted air volume calculating unit 25 calculates the speed of each vehicle during the measurement cycle, the resistance coefficient of each vehicle determined for each vehicle type, and each vehicle. Is calculated from the projected area of the vehicle, and the total air volume of the vehicle is calculated. In addition, the air flow due to the natural wind is predicted from the amount of change in the air flow due to the natural wind from the detection result of the natural airflow detecting unit 5. This prediction is performed by performing a regression analysis or the like for each change in the airflow. Then, the sum of the calculated airflow by each vehicle and the airflow by the predicted natural wind is calculated as the predicted airflow.

In this case, the air flow of each vehicle is assumed to be the air flow obtained from the detected parameters as it is, because it is considered that there is no change in the parameters because the measurement cycle is short. . However,
A traffic volume prediction unit 22 as described in a second embodiment described later may be provided, and the airflow volume of each vehicle may be predicted from the amount of change in traffic volume for each vehicle.

The predicted soot concentration distribution generating unit 17 translates the predicted soot concentration distribution obtained as the air volume 0 by the calculated predicted air volume in parallel. For example, assuming that the predicted air volume is W and the wind speed is M (m / min) in consideration of the cross-sectional area of the tunnel, the control cycle is 1 minute, and the smoke concentration distribution is parallel by M (m). Moving, the predicted soot concentration distribution in FIG. 8 is as shown in FIG. This allows
The portion to be ventilated is L2 from the tunnel exit, and requires less ventilation than when the predicted airflow is not taken into account. In addition, when the wind during the control cycle is blowing from the exit to the entrance of the tunnel, if this is not taken into consideration, the necessary ventilation may not be obtained. , This can be prevented.

(Second Embodiment) In the first embodiment, the predicted vehicle position calculating section 15 does not consider a vehicle newly entering the tunnel. This is because, in the present invention, since the smoke distribution is generated by detecting the vehicle speed, the control cycle can be shortened regardless of the tunnel length. This is because it is possible not to affect the tunnel exit.

However, when the control cycle is long or when the inside of the tunnel is an oncoming lane, it is necessary to predict a new incoming vehicle. Therefore, Embodiment 2
Is configured to be able to predict a new incoming vehicle. FIG. 13 shows a functional block diagram of the tunnel ventilation control device according to the second embodiment. This apparatus is also assumed to be included in a system having a schematic configuration as shown in FIG. This tunnel ventilation control device is different from the tunnel ventilation control device according to the first embodiment in that a traffic volume detection unit 3a is provided.
C is provided with a traffic volume prediction unit 22 and a vehicle speed average value prediction unit 23.

The traffic detector 3a detects the traffic during the measurement period, and uses the traffic / vehicle type detector 3 shown in FIG. The traffic volume prediction unit 22 is a unit for predicting the traffic volume up to the elapse of the control cycle from the detected traffic volume variation, and specifically predicts the traffic volume from the traffic volume variation by regression analysis. The vehicle speed average value prediction unit 23 predicts the average value of the vehicle speed until the control cycle elapses from the vehicle speed change amount detected by the vehicle speed detection unit 2. Specifically, the average value of the vehicle speed is calculated for each measurement period, and the amount of change in the average value is also subjected to regression analysis, thereby predicting the average value of the vehicle speed until the control period elapses.

Next, the operation of the tunnel ventilation control device having the above configuration up to generation of the soot concentration distribution of the inflowing vehicle will be described. FIG. 14 shows a flowchart illustrating the operation according to FIG. First, the vehicle speed detector 2 and the traffic detector 3a detect the vehicle speed and the traffic of the vehicle entering the tunnel during the measurement cycle, respectively (S201, S202, S203). Subsequently, the vehicle speed average value prediction unit 23 calculates and records the average value of the vehicle speed during the measurement period (S204), and the traffic volume prediction unit 22 extracts and records the traffic volume during the measurement period (S205).

After performing the above operation for the control period (S20).
6), the vehicle speed average value prediction unit 23 predicts the average value of the vehicle speed until the next control cycle elapses from the recorded amount of change in the average value of the vehicle speed (S207). At the same time, traffic volume prediction unit 2
2 predicts the traffic volume until the next control cycle elapses from the recorded change amount of the traffic volume (S208). Then, the predicted vehicle position calculation unit 15 further calculates the predicted vehicle position of the vehicle predicted to flow into the tunnel (S209). That is, the vehicle predicted to flow first during the control cycle moves a distance of (average vehicle speed) × (control cycle) from the entrance of the tunnel after the control cycle has elapsed, and the amount of traffic predicted in this section Since there are vehicles of the same number traveling at the same speed, the inflow vehicles are calculated as being equally distributed in this section.

For example, when the control cycle is one minute, the predicted traffic volume is three and the predicted average vehicle speed is 3a (m
/ Min), three vehicles will flow into the tunnel during the control cycle, and the first vehicle will be 3
Since the vehicle travels a × 1 (m) and the vehicles are equally distributed in this section, the positions of the vehicles are a (m), 2a (m), and 3a (m) from the entrance as shown in FIG. Becomes It should be noted that the predicted vehicle position calculator 15 also calculates the position of the vehicle already in the tunnel. This operation has been described in the first embodiment and will not be described.

Then, on the basis of this, the predicted soot concentration distribution generating unit 16 generates the soot emission distribution of each vehicle during the control cycle for each vehicle including the inflowing vehicle as the predicted soot concentration distribution for each vehicle. (S210). At this time, the smoke emission amount of the inflowing vehicle is set by the smoke emission amount setting unit 12 based on the average vehicle speed predicted by the vehicle speed average value prediction unit 23 and the vehicle type set as a fixed value. For example, when the predicted vehicle position as shown in FIG. 15A is calculated for the inflow vehicle, the soot emission amount of the inflow vehicle is K4 (m ³ /
When m) is set, the soot concentration distributions for the three inflow vehicles are as shown in FIGS. 15B, 15C, and 15D.

The predicted soot concentration distribution of each incoming vehicle generated as described above is as shown in FIGS. 7 (a), 7 (b) and 7 (c).
The predicted soot concentration distribution generation unit 17 superimposes the predicted soot concentration distribution of the vehicle that has already flowed in, and provides the predicted soot concentration distribution. With such an operation, it is possible to generate a predicted soot concentration distribution in consideration of the soot concentration of a vehicle that will newly flow.
The operation of the other configuration of the control unit 1C is the same as the operation of the control unit 1A of the tunnel ventilation system according to the first embodiment, and thus the description is omitted here.

(Embodiment 3) In the tunnel ventilation control apparatus according to Embodiment 1, the soot concentration distribution is generated by calculating the vehicle position for each vehicle entering the tunnel, which will be described below. It can be simplified like a tunnel ventilation control device. FIG. 16 shows a functional block diagram of a first tunnel ventilation control device according to the third embodiment. This device is also included in a tunnel ventilation control system having a schematic configuration as shown in FIG. This tunnel ventilation control device is different from the tunnel ventilation control device according to Embodiment 1 in that a traffic volume detection unit 3a is provided and an average vehicle speed calculation unit 20 is provided in the control unit 1D. .

The traffic detector 3a detects the traffic during the measurement cycle, and uses the traffic / vehicle type detector 3 shown in FIG. The average vehicle speed calculation unit 20 calculates an average vehicle speed that is an average value of the vehicle speed detected by the vehicle speed detection unit 2 during the measurement cycle. In the tunnel ventilation control device, the vehicle position calculation unit 11 does not calculate the position of each vehicle from the vehicle speed of each vehicle calculated by the vehicle speed detection unit 2 and the time when the vehicle passed the vehicle speed detection unit 2. The position of each vehicle is calculated from the traffic volume detected by the traffic volume detection unit 3a and the average vehicle speed calculated by the average vehicle speed calculation unit 20.

The operation up to generation of the soot concentration distribution for each vehicle in the tunnel ventilation control device having such a configuration will be described below. FIG. 17 is a flowchart showing this operation. First, the vehicle speed detector 2 and the traffic detector 3a detect the vehicle speed and the traffic of the vehicle entering the tunnel during the measurement cycle, respectively (S301, S302, S303). Next, the average vehicle speed calculation unit 20 calculates the average vehicle speed in the measurement cycle (S304).

Subsequently, the vehicle position calculation unit 11 extracts the detected traffic volume (S305), and calculates the position of each vehicle after the measurement cycle has elapsed from the traffic volume and the calculated average vehicle speed (S306). Specifically, from the entrance (average vehicle speed) ×
The vehicle position is calculated assuming that the vehicles of the traffic volume measured in the section up to (measurement time) are equally distributed. Also,
Naturally, the vehicle position calculator 11 also calculates the position of the vehicle already in the tunnel. The position of the vehicle already in the tunnel is the position of each vehicle calculated in the previous measurement cycle, (average speed in the previous measurement cycle)
What is necessary is just to move in parallel to the tunnel exit by X (measurement period).

Specifically, for example, if the average vehicle speed in the current measurement cycle is 2b (m / min) and the traffic volume is two, as shown in FIG. 18, 2b × 1 (m)
Are calculated so that two vehicles are distributed at equal intervals in the section of. If it is calculated at the end of the previous measurement cycle that three vehicles have already been equally distributed in the section c (m), the position of the vehicle already in the tunnel is After the measurement period elapses, it is calculated that the position is further advanced by c (m) while maintaining the distribution as shown in FIG. 19B.

Thereafter, the vehicle-specific soot concentration distribution generating unit 13 calculates the amount of movement of each vehicle derived from the difference between the position of each vehicle in the previous measurement cycle and the current position of each vehicle, and the soot emission setting unit 12. Then, a smoke concentration distribution generated for each vehicle is generated from the set smoke emission amount (S309). The following operation is the same as that of the tunnel ventilation control device according to the first embodiment, and a description thereof will be omitted.

In the above-described tunnel ventilation control device,
Although the calculation of the vehicle position is simplified by using the average value of the vehicle speed, it is possible to further simplify the calculation by setting the vehicle speed as a fixed value. The tunnel ventilation control device having such a configuration will be described as a second tunnel ventilation control device according to the third embodiment. FIG. 20 shows a functional block diagram of the second tunnel ventilation control device. The second tunnel ventilation control device is different from the first tunnel ventilation control device in that the vehicle speed detection unit 2 and the average vehicle speed calculation unit 20 are replaced with a vehicle speed setting unit 21.

The vehicle speed setting section 21 sets the vehicle speed of the vehicle flowing into the tunnel to a predetermined average vehicle speed. The average vehicle speed is determined based on past results. This setting may be completely fixed, or may be changed depending on the day of the week, time of day, or the like. The operation of the tunnel ventilation control device having such a configuration is almost the same as that of the first tunnel ventilation control device, and detects the vehicle speed (S301) and calculates the average vehicle speed (S30).
Only 4) is omitted. However, since the vehicle speed is constant over the continuous measurement cycle, the calculation in the vehicle position calculation unit 11 can be further simplified.

That is, a vehicle flowing from the entrance in one measurement cycle advances by (average vehicle speed) × (measurement cycle), and vehicles corresponding to the traffic volume in the measurement cycle are distributed at equal intervals in this section. This is the same as the first tunnel ventilation control device described above. However, since the average speed is always constant, each section moves in the traveling direction by the same distance as the section each time the measurement period elapses.

Referring to the drawing, it is assumed that the distribution of vehicle positions is as shown in FIG. Each of the blocks A to D is a section in which the vehicle travels in each measurement cycle, and the vehicles corresponding to the traffic amount detected at the time of inflow are located at equal intervals in each block. The width is equal to the distance that the average vehicle speed travels in one minute of the measurement cycle as d (m / min). After one measurement period, FIG.
In FIG. 21A, each block moves to the position of an adjacent block as shown in FIG. Note that the number and position of vehicles in each block do not change. However, FIG.
For the first block E in (b), a new calculation is made from the traffic detected in the current measurement cycle. As described above, since the vehicle position already existing in the tunnel only needs to be translated in the next block, the calculation is further simplified.

(Embodiment 4) The tunnel ventilation control system according to Embodiments 1 to 3 controls one tunnel with one control device. However, as shown in the tunnel schematically shown in FIG. 22, when not only the jet fan F but also a dust collector Ff, a shaft blower Fo, and a shaft exhaust Fi are provided in the tunnel as ventilators, these ventilators are used. Since soot can be removed at the place where the machine is located, the ventilation is controlled by using this portion as an outlet. In such a case, the tunnel may be divided into sections x1, x2,... Xn in FIG. 22, and the tunnel ventilation systems according to the first to third embodiments may be provided in series for each section.

FIG. 23 shows a functional block diagram of a system in which the tunnel ventilation control device according to the first embodiment or the like is provided in series as the tunnel ventilation control device system according to the fourth embodiment. In addition, this tunnel ventilation control device system does not simply provide the tunnel ventilation control device according to the first embodiment and the like in series.
The feature is that X is shared.

The shared ventilator control unit 19X adjusts the influence of the ventilation from the ventilator F in other sections in each section, and can achieve the ventilation rate calculated by the ventilation rate calculating means in each section. Next, the ventilator for all sections is controlled. That is, for example, when the ventilation volume in the section x2 is L2, the ventilation volume L2 is set only by the ventilator F2 in the section x2.
Need not be achieved. This is because, in the other sections, since the ventilator is operated to achieve the required ventilation rate, some airflow is also sent in the section x2 due to their influence. In other words, the ventilation by the ventilator F in each section affects each other, so that by adjusting these and operating the ventilator to the minimum necessary, power consumption can be saved.

The operation of the tunnel ventilation control system having the above configuration will be described. First, each section x1, x2,.
.. Xn calculates the required ventilation volume for each xn. At this time, in the section located second from the entrance, soot that has not been completely removed by the dust collector, the shaft blower, or the shaft exhaust is mixed into the air flowing from the entrance of the section. For this reason, when the smoke density distribution generating unit 14 generates the smoke density distribution, the entrance is outside air in a section (for example, section m in FIG. 6 (b)) in which the smoke density distribution is parallel-translated by the air volume detected by the wind speed detecting section. In the case of, the smoke concentration is set to 0, but the smoke concentration determined by the performance of the ventilator is added to the distribution in the second and subsequent sections from the entrance.

Then, the ventilator control unit 19X adjusts and selects the optimum combination of the ventilators that can achieve the required ventilation volume in each section, and selects the ventilators F1, F2,.
Activate Fn. In FIG. 23, the vehicle type detection unit and the vehicle speed detection unit are provided separately, but those provided at the entrance of the first section may be shared, and the wind speed detection unit is also installed in the tunnel in the shaft. If there is neither a wind fan nor a shaft blower, the wind speed in the tunnel is constant and can be used.

As described above, the present invention has the following effects. First, in the present invention, the wind speed detecting means detects the wind speed in the tunnel, and the vehicle speed detecting means detects the speed of the vehicle passing through the tunnel. Then, the vehicle position calculating means calculates the position of each vehicle at a predetermined measurement cycle from the detected vehicle speed, and the vehicle-specific soot concentration distribution generating means sets a soot emission amount preset for each vehicle; From the amount of movement of the position of each vehicle during the measurement cycle, the distribution of soot discharged by each vehicle during the measurement cycle is generated as a soot density distribution per vehicle, and the soot density distribution generating means generates the soot density per vehicle. A smoke concentration distribution in the tunnel is generated for each measurement cycle from the distribution, the detected wind speed in the tunnel, and the smoke concentration distribution in the tunnel one measurement cycle before. On the other hand, the predicted vehicle position calculation means calculates the vehicle speed and the position of each vehicle after a predetermined control cycle has elapsed from the calculated position of each vehicle. From the previously set soot emission amount and the movement amount of the position of each vehicle after the control period has elapsed, the distribution of the soot discharged by each vehicle during the control period is generated as a predicted soot concentration distribution for each vehicle, The predicted soot concentration distribution generating means generates the soot concentration distribution after the control cycle period as the predicted soot concentration distribution from the generated soot concentration distribution and the predicted soot concentration distribution for each vehicle. Then, the ventilation amount required during the control cycle is calculated from the predicted soot concentration distribution generated by the ventilation amount calculation unit, and the ventilation unit control unit controls the ventilation unit according to the calculated ventilation amount.

As described above, since the tunnel ventilation control device according to the present invention calculates the soot concentration distribution in the tunnel based on the vehicle speed of the vehicle in the tunnel, the soot concentration in the tunnel is accurate regardless of the length of the tunnel. Since the distribution can be generated and predicted, more precise and detailed tunnel ventilation control can be realized. Further, in this tunnel ventilation control device, a traffic amount detecting means is provided, and further, an average vehicle speed calculating means or a vehicle speed setting means is provided, and the vehicle position calculating means is provided with a detected traffic amount, and a calculated or set traffic amount. If the position of each vehicle is calculated for each elapse of the measurement cycle from the average vehicle speed, the calculation in the vehicle position calculating means can be simplified, and the load on the arithmetic unit can be reduced, and the vehicle position can be calculated more quickly. It becomes possible.

Further, the above-mentioned tunnel ventilation control device is provided with a traffic volume detecting means, a traffic volume predicting means, and a vehicle speed average value predicting means, and the predicted vehicle position calculating means is adapted to calculate the average value of the predicted traffic volume and the vehicle speed. Taking into account, including the predicted inflow vehicle, if the position of each vehicle after the control cycle elapses is calculated, when the control cycle is long, soot discharged by the newly inflowing vehicle will be reduced. , When it affects the amount of soot emissions
A predicted soot concentration distribution is generated in consideration of the soot concentration of the vehicle that is predicted to newly flow in, and appropriate tunnel ventilation control can be performed.

In the above tunnel ventilation control device, if the vehicle type discriminating means and the soot emission setting means are provided,
The vehicle type determining means determines the type of vehicle passing through the tunnel, and the smoke emission amount setting means sets the smoke emission amount preset for each vehicle according to the determined vehicle type and the detected vehicle speed. As a result, the soot concentration distribution for each vehicle can be generated more accurately according to the vehicle type, and the accuracy of tunnel ventilation control can be improved.

Then, in the tunnel ventilation control device, underground air flow detecting means and predicted air flow calculating means are provided.
If the predicted soot concentration distribution generating means generates the predicted soot concentration distribution in consideration of the calculated predicted air volume, the movement amount of the predicted soot concentration distribution due to the mine wind blown into the tunnel during the control cycle period. In consideration of this, more effective tunnel ventilation control can be performed.

When the ventilation amount calculating means determines that the predicted soot concentration distribution has a concave portion having a predetermined width or less,
If the ventilation amount is calculated assuming that there is no concave portion, when a part where the smoke concentration distribution is partially low suddenly occurs, this is ignored, and the smoke exceeds the predetermined value as a whole. The ventilation volume can be calculated from the area, more appropriate control can be performed, and control in consideration of the ventilation capacity per one ventilator can be performed.

In the tunnel ventilation control device system according to the present invention, the ventilator control means shared by each tunnel ventilation control device adjusts the influence of the ventilation from the ventilation means in other sections in each section, In each section, so as to achieve the ventilation rate calculated by the ventilation rate calculation means,
Since the ventilation means in all sections is controlled, efficient control of the ventilation means can be performed, which can contribute to saving power consumption and the like.
