Description

Technical Field [0001] The present invention relates to an emergency exit door control circuit for an unmanned electric vehicle and a control circuit for the unmanned electric vehicle,

The present invention relates to an emergency exit door control circuit for an unmanned electric vehicle and, more particularly, to a control circuit for forcibly opening an emergency door installed in front of an unmanned electric vehicle only when a special condition is met, To an unmanned electric vehicle equipped with a control circuit.

A train can connect several vehicles to carry and carry hundreds to thousands of passengers at once, thus playing a major role in relieving traffic accidents in densely populated urban areas.

The train is riding or getting off the passenger through a door that is automatically opened or closed in a station installed on the ground or the ground.

In other words, the door can be opened and closed automatically by the train control device under the control of the control room managing the train operation.

When the above-mentioned electric vehicle is used, the electric power of the electric train is sometimes not supplied, so that a trouble occurs, or even an emergency such as a fire accident or an explosion accident occurs.

Rapid evacuation of passengers is very important when the emergency occurs. For this purpose, the doors must be opened promptly regardless of the failure of the train, and manual opening and closing means must be provided to manually open and close the doors.

However, the above door is installed on the left or right side of the electric vehicle. When the door is lowered by using the left door or the right door, there is a danger due to vehicle interchange in the underground section, and there are many sections without emergency escape route. There is a safety risk of the vehicle.

Therefore, in recent years, the importance of passenger safety is rising, so it is required to provide a door structure capable of emergency evacuation (escape) of passengers such as a front entrance door of a train car. In addition, an emergency door, Allowing passengers to evacuate quickly.

On the other hand, Article 39 (Cab) ② of the Urban Railway Act states that 'the cab must have at least one emergency exit in case of an emergency, and the passenger should be able to escape easily' As described above, if a passenger escapes by using a passenger access door on the side of the underground section, the passenger may be more dangerous by the interchange vehicle.

In Korea, it is possible to automatically operate the subway or each local government light railway through the signal system. However, in some railway vehicles except for the light railway, the driver will be aboard the driver's cab even in automatic operation.

In the event of an emergency situation, the driver can directly handle the front door emergency doors, so no special control is required. However, in the case of an unmanned train in which the driver does not board, the passenger must handle the front door emergency doors directly in case of an emergency.

Therefore, in a train, the emergency door should be controlled so that passengers can manually open and exit the front emergency door, but emergency doors should be controlled in consideration of safety.

For example, there is a problem that if a passenger can handle an emergency door by opening an unmanned train, the risk may be increased.
