の風圧によっては走行上危険でもある。(Problem to be Solved by the Invention) However, since the cross-sectional area of the vehicle (2) occupies most of the cross-sectional area of the tunnel (1), when the vehicle (2) runs inside the tunnel (1), the cross-sectional area of the vehicle (2) ) causes a piston action,
Wind pressure is generated in front of the vehicle, and the exhaust by the exhaust fan (4) cannot suppress the wind pressure, which in turn exposes the passengers on the platform (9) of the next underground station (8) to the wind pressure of the acid. Not only does it make you feel uncomfortable, but depending on the wind pressure, it can also be dangerous when driving.

The air volume of the blower/exhaust fan is controlled based on the air flow rate to suppress the wind pressure caused by the vehicle running.

うに構成されている。According to this embodiment, the platform of underground station (8)
(9) Vehicle (2) An airflow detector, that is, an anemometer (lO), which sequentially measures the airflow in the direction in which the vehicle is traveling in the tunnel, is installed at the end position on the approach side. This anemometer (lO) sequentially measures the change in wind speed in the direction of vehicle travel in the tunnel when the vehicle is running, that is, the train wind, and sends the detection results to the control device (7). The control device (7) is connected to the anemometer (l
Based on the wind speed information from O), the air volume of the blower (5) and the exhaust fan (6) is controlled so that the wind speed is below a set value.

歩行時の危険性を回避することができる。In other words, as shown in the figure, wind pressure is generated in front of the vehicle (2) by the piston action until the vehicle (2) reaches the platform (9).
In this embodiment, the exhaust air volume of the exhaust fan (6) is controlled to be increased via the control device (7) based on the detection result of the anemometer (lO). Therefore the vehicle
Platform (9) of underground station (8) where (2) enters
The wind pressure in the vehicle is suppressed, thereby avoiding discomfort for passengers or danger when walking.

の各方法を適宜組み合わせることによって風圧による弊
害を防止することができる。In addition, the wind pressure caused by the running of the vehicle can be reduced by reducing the amount of air blown from the blowing hunting ground (3) located behind the vehicle (2), or by reducing the amount of air blown from the blowing hunting ground (3) located in front of the underground station (8). It is also possible to suppress the wind pressure by causing wind pressure resistance by increasing the amount of air blown. In addition, by appropriately combining these methods, it is possible to prevent adverse effects caused by wind pressure.
風速計（ｌＯ）の出力が設定値以下となればその送排風

作動する制御装置（７）によって通常の換気運転に戻る
ことになる。When the output of the anemometer (lO) falls below the set value, the blower/exhaust fan (5), (6) will return to normal ventilation operation by the control device (7) which operates according to the time schedule.

は勿論のことであり、またその電動機としては回転数制
御、回生制動できるものとを用いることが好ましい。It goes without saying that the control of the blower (5) and the exhaust fan (6) must be able to sufficiently follow the travel interval of the vehicle (2), and the electric motor must be able to control the rotation speed, regenerative braking, etc. It is preferable to use one that can be used.

う利点がある。In this example, an anemometer (10) is used as the airflow detector, but a differential pressure gauge may also be used. This has the advantage that it is also possible to determine whether the train wind is the wind when the vehicle approaches the platform or the wind after the vehicle passes.

待することができる。In addition, in the above embodiment, the air volume detector is installed on the platform (
A device installed at the end position of the vehicle (2) on the approach side of 9) and controlling the air volume of the blowers and exhaust fans (5) and (6) until just before the vehicle (2) approaches the platform (9). However, the above air volume detector may be used as an exhaust fan (6
), and in this case, the same effects can be expected, although the control accuracy will be slightly lower than in the above embodiment.
