I believe that everyone has the experience of taking a high-speed rail or a bullet train, and also has an impression of the display screen inside, on the top of the two ends of the carriage, so important position, in addition to displaying speed, temperature, station name, arrival time, toilet use status, etc., basically there is no other information, and the screen is also the most primitive Led bulb, a high-speed rail is so expensive to manufacture costs, no matter how not bad is an advanced LCD screen?
For this reason, I specifically checked it, and the above information is displayed, mainly because:
1. Passenger Information Request:
Speed: High-speed rail is known for its high speeds, and for many passengers, learning about the actual speed at which the train is running is a novel and interesting experience. The display in the high-speed rail carriage shows the speed, satisfying the passengers' curiosity about the train's performance, while also providing intuitive travel status information. Passengers can use real-time speed to know whether the train is running on time and how the speed changes in different sections (e.g., acceleration, cruise, deceleration).
Temperature: The temperature inside the cabin has a direct impact on the comfort of passengers. High-speed trains are usually equipped with a thermostatic air conditioning system, and the display screen shows the temperature inside and outside the carriage to help passengers determine whether they need to adjust their clothing or report temperature discomfort to the crew for a better travel experience. In addition, for passengers with special needs, such as children, the elderly, or special health conditions, knowing the real-time temperature can help them take personal measures to keep warm or cool down.
2. Security and trust building:
The display speed can convey the stability and safety of the high-speed rail system. Passengers will be able to see that the train remains smooth at high speeds, increasing trust in the technical maturity and operational management of the high-speed rail. This transparent information transmission helps to alleviate the tension that some passengers may have due to high-speed driving, and improves their sense of safety.
The temperature display is also relevant to the passenger's sense of safety, especially in extreme weather conditions, and passengers can be sure that the climate control system in the cabin is working properly to ensure that the environment is suitable during the journey.
3. Technology display and brand image:
- As a high-end and modern means of transportation, high-speed rail displays advanced data such as speed on its internal display screen, which is not only a display of its advanced technology, but also a means to enhance the brand image of a country or enterprise. Through real-time speed display, high-speed rail operators can demonstrate their technological strength and service level in the field of rail transit to domestic and foreign passengers.
4. Practical functions and resource utilization:
The interior space of high-speed rail carriages is limited, and the design of the display screen needs to take into account the effective transmission of information and the simplicity of the interface. Speed and temperature are among the most important parameters directly related to passengers, and the priority display of this information is in line with the principles of practicality and resource optimization. Other information that may need to be displayed (e.g. arrival time, station ahead, carriage number, etc.) is usually provided via a separate display or PA system.
5. System design and technical limitations:
The electronic display system inside the high-speed rail is pre-designed and integrated, and its function settings, information presentation format and update frequency are all based on specific technical standards and user research. When designing, engineers focus on presenting in real time the key data that passengers care about most and that has a significant impact on travel. Speed and temperature, as the core indicators that directly affect passenger perception, are naturally the first choice.
Based on the above considerations, the display screen in the high-speed rail carriage displays this information. It's just that I don't understand why such an advanced high-speed rail still uses such an old display screen, and we spend so much money that we can't even afford a decent LCD screen?
If you can advertise to generate income, I'm afraid you will replace it with an LCD screen as soon as possible, I'm afraid it's still the iron boss's sense of service that is doing tricks, in their consciousness, I'm afraid there is no such concept, right?
