Description

Technical Field

[0001] The present invention relates to the technical field of railway platform construction, and in particular to a platform carriage number dynamic display landmark system based on wireless signal and power supply technology. Background Art

[0002] In the prior art, high-speed railway platforms use fixed colored digital landmarks as a way to remind passengers to find their carriage numbers, which has many disadvantages:

[0003] 1) Color landmarks come in a variety of colors, each with a different carriage number, and stations often fail to provide adequate reminders when trains stop, making it difficult for passengers to obtain correct information and leaving them at a loss.

[0004] 2) Color landmarks are suitable for most people, but they are ineffective for people with color blindness or color weakness. This type of landmark method ignores the needs of minority groups and may have adverse consequences, leading to greater social impact.

[0005] 3) The existing landmarks are in the form of labels attached to the ground of existing platforms. The landmarks themselves are prone to wear and tear, and the colloid is prone to aging and falling off. Overall, this type of landmark facility has poor durability and requires a large amount of maintenance work in the later stage.

[0006] 4) The existing landmarks are fixed landmarks that can only indicate the carriage number, but not the size and direction of the seats in each carriage. This will cause passengers to walk towards each other when looking for seats on the train, greatly reducing the speed of passengers looking for seats, affecting their mood, and easily inducing conflicts between passengers. From the perspective of the station, it also prolongs the time it takes for passengers to board the train and reduces overall operational efficiency.

[0007] Therefore, how to improve the display accuracy and real-time performance of train carriage numbers on railway platforms has become a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0008] In view of the above-mentioned defects of the prior art, the present invention provides a platform car number dynamic display landmark system based on wireless signals and power supply technology.
