Abstract

The present invention relates to a control system for opening and closing doors of subways, trains, and the like, and to reducing electric energy used for indoor air-conditioning of subways. The task is to reduce the energy required. All doors in the train are opened and closed simultaneously, regardless of the passenger who gets on or off, so that only the door can be opened and closed only when the passenger needs to get on and off. By not opening and closing at the same time, the indoor temperature of the electric vehicle is maintained at the maximum, thereby minimizing the change in the indoor temperature caused by the opening and closing of the door of the electric vehicle, thereby reducing the energy required for heating and cooling. Energy saving according to the number of door opening and closing and minimizing the temperature change of the indoor temperature maintenance in the train can greatly reduce the energy used to maintain the indoor temperature.

Description

Door opening and closing control method of subway electric train {METHOD FOR CONTROLLING OF SUBWAY DOOR}

The present invention relates to a method for controlling the opening and closing of a door of an electric vehicle for maintaining room temperature in a subway electric vehicle.

Subway, a means of public transportation, uses a lot of energy to maintain indoor temperatures in trains. Especially during the summer and winter, a lot of energy is required to maintain the room temperature inside the train. When stopping at each station over the entire section, the entrance and exit doors are opened and closed at the same time by the crew (one station, one door and four doors). It is efficient to open and close all the doors at the same time (e.g. transfer stations, crowded areas) with a large number of passengers. The opening and closing of the electric door has the most influence on the indoor temperature change in the electric car and the energy change for maintaining the temperature is the most severe. In addition, all the doors without getting on and off the passengers are automatically opened and closed to waste energy for maintaining the indoor temperature. Therefore, there is a need for a method for controlling the opening and closing of an electric vehicle door that can maintain room temperature in the electric vehicle.

The door opening / closing control method of the subway train is installed inside the subway train, and the touch of the passenger to get off the passenger detection signal to the door operation control unit (touch sensor) to operate the interior of the subway train to get off the subway platform Detecting presence; Is installed in the subway platform, if the movement is detected at a position spaced apart from the point where the door is located when the subway train is stopped from the operation of the infrared sensor for transmitting a passenger detection signal to the door operation control unit Detecting the presence of a passenger to board the subway train; And when the at least one of the getting off passenger detection signal and the getting on passenger detection signal is received by the door operation control unit and the subway train stops at the platform.

The operation of the subway to stop at the platform and to open and close the door for getting on and off the passengers has the greatest influence on the indoor temperature of the train. The subway uses a lot of energy to maintain room temperature while driving, and it uses more energy to change the temperature when getting on and off. In general, it is efficient to open and close all the doors at the same time because there are many passengers moving at the commute, passenger density station and transit station. However, in the history other than the above object, it can be said that it is not efficient to perform the operation of simultaneous opening and closing of all doors in the train. It is said that it requires a lot of energy consumption to minimize the number of doors operating (4 stations per station, 1 door) and the change in the indoor temperature. By detecting and applying the passengers to get on and off, the doors of the subway can be opened and closed to save energy for maintaining the temperature inside the train and to provide passengers with a more comfortable and quality ride by minimizing temperature changes in the train. Will be.

Figure 1 shows the opening and closing operation of the electric car door for getting on the subway in the platform.

Referring to FIG. 1, the passenger receives a notification broadcast that the subway is about to arrive at the platform and approaches the door, and stands in front of the door and stops in front of the yellow stop line 13 on the floor. On the basis of the yellow stop line 13, where passengers wait, the boarding board detects movement detection infrared sensors 10a and 10b for detecting movement, and indicators 11a and 12a indicating opening and closing of subway doors are provided at the lower end of the ceiling. Install. When the infrared sensor 10a detects a waiting passenger, the indicator 12a lights up and flashes to indicate that the door is opened. The designated door 36a is opened when the subway stops. The ride detection sensor 10b detects that there are no passengers waiting for a ride, and the door indicators 11b and 12b do not operate and notify that the door 36b does not open in a blinking state. The designated door 36b does not open when the subway stops.
