[0019] The rail transit equipment has a cultural tourism planning mode. The dynamic map records the time H when the rail transit equipment is about to arrive at the station and transmits it to the video playback system. The video playback system stores several city cultural tourism promotion videos, and each city has several promotion videos. The duration of each promotion video is different. The first step is to select a city. According to the location of the rail transit equipment, the corresponding city cultural tourism promotion video is selected. The second step is to select a promotion video with a duration less than or equal to H according to the duration H, so that passengers can watch the entire city cultural tourism promotion video before arriving at the station. If there is no promotion video with a duration less than or equal to H, the city cultural tourism promotion video with a duration closest to the H value is selected, so that passengers on the rail transit equipment can spend time on the rail transit equipment to understand the local conditions and customs of the destination city before arriving at the city. Passengers who are not in the destination of this city will also have some understanding of this city after watching it. The culture and tourism of each city are promoted during this time period to avoid ineffective waste of travel time. The video playback system is only used during non-boarding and alighting hours.

[0020] The video surveillance system is divided into in-car monitoring and out-car monitoring. The out-car monitoring is to monitor the people on the platform through a panoramic camera, and before the door is opened, the infrared video of the waiting people outside the door in front of each carriage is displayed on the internal display at the door. Passengers in the rail transit equipment can observe the images of the waiting people outside and choose the corresponding door with fewer people to get off, so as to avoid the concentration of people getting on and off at one door, thereby reducing the probability of accidents. In-car monitoring uses a dome camera to monitor passengers on the inside of the door, and displays the infrared image of the people on the inside of the door on the LCD monitor. Passengers who have not left their seats can choose the door with fewer people by watching the LCD monitor. Through in-vehicle and out-vehicle monitoring, passengers can be diverted to avoid large-scale gathering of people in the same area; For passengers over 70 years old and pregnant women, the broadcasting system is used to broadcast reminders. When purchasing a ticket, each passenger enters whether she is a pregnant woman into the crew system, and the passenger information is transmitted to the video system through the crew system. The broadcasting system plays the seat numbers of passengers over 70 years old and pregnant women through the passenger compartment speakers, reminding passengers in rail transit equipment to give way to passengers with the above seat numbers, and urging passengers to let passengers over 70 years old and pregnant women get off first to avoid squeezing. At the same time, the side display shows that the passengers getting off this car include passengers over 70 years old and pregnant women, and the external speaker broadcasts the voice "The passengers getting off this car include passengers over 70 years old and pregnant women".

[0021] The video surveillance system uses panoramic cameras to observe the external climate of the rail transit equipment, which is divided into rainy days and sunny days. After the LCD display plays the city's cultural and tourism promotional video, if the station has not been reached, the LCD lighting system will control the internal lighting system according to the external weather conditions. If it is a rainy day, the brightness of the interior lighting of the car will be automatically dimmed. If it is a sunny day, the internal lighting system will be turned on as usual, reminding passengers of the external climate of this section of the road in the form of lights, so that they can be prepared for the weather after getting off the train.

[0022] The front-view camera and rear-view camera observe the movement of rail transit equipment and the path ahead in real time. If an emergency occurs in front or behind the observation value, and emergency parking and evacuation of passengers are required, the driver will report the situation through the microphone in the driver's cabin, and control the video system to emergency mode on the LCD touch screen. The video mode of all passenger emergency intercom units is turned on, and the evacuation path of this car is displayed on the display of the passenger emergency intercom unit and the LCD display; The evacuation route is determined by the real-time video recorded by the panoramic camera, and is divided into the safety window evacuation route and the door opening and closing evacuation route. The video system analyzes the current environment of the rail transit equipment and displays the specific escape method on the display of the passenger emergency intercom unit and the LCD display. The evacuation route of each carriage is different. Whether this evacuation route can be used is determined based on the environment of each carriage. The safety window evacuation route requires flat ground on both sides of the carriage. Evacuation cannot be carried out in the slope area to avoid passengers being injured during the evacuation. The door opening and closing evacuation route can be carried out in all environments. The terrain outside the rail transit equipment is also displayed on the LCD display to guide personnel to leave the vicinity of the rail transit equipment to avoid people being blocked near the rail transit equipment, causing passengers inside the rail transit equipment to be unable to get out. Automatically plan the evacuation route. Passengers evacuate according to the evacuation route shown on the LCD display to avoid blind evacuation and passenger squeezing. At the same time, prompt voice is played in the external speakers and cabin speakers, with children, pregnant women and the elderly given priority. The dome camera uses dynamic capture mode to check if there are people with mobility problems. If so, the camera locates the passenger and calls the driver's cab for help. The internal display, side display, and destination display of the display are long strip displays, and the LCD display is an LCD display screen, and the electronically controlled bearing is installed in the car for passengers to use; If it is nighttime, all lighting systems will be turned on to help people evacuate.
