Description

Technical Field

[0001] The present invention relates to the field of LED travel information technology, and in particular to a mobile LED travel information and control service terminal. Background Art

[0002] The mobile LED road traffic information display screen is an LED display device designed for mobile traffic environments. It uses a professional long-range high-brightness LED light array screen that can switch to display different patterns and text content. This display screen also has an original folding method that can be quickly unfolded and folded, which is not only convenient to use, but also enhances safety. The equipment is powered by a replaceable lithium battery and can continue to perform warning tasks. In addition, the product is sturdy and reliable and can be used normally in harsh weather environments. This display screen is widely used in traffic law enforcement, public safety, power repair, communication construction, and municipal construction.

[0003] The existing mobile LED travel information and control service terminal cannot fold and store the LED display screen for protection. Therefore, when the LED travel information and control service terminal is towed by a car, it is easy to cause the LED display screen to be damaged and unusable due to factors such as strong winds and accidental collisions during the movement. In addition, the existing mobile LED travel information and control service terminal is often powered by a battery, and the device will become unusable after the battery is exhausted.

[0004] Our R&D department considers the following solutions:

[0005] Improve the folding and storage design of LED display: In order to protect the LED display, it is possible to consider designing a foldable LED display so that it can be folded up during movement to reduce damage to the LED display caused by strong winds, accidental collisions, etc. At the same time, a protective cover or protective shell can be designed to wrap the LED display in it to further enhance its ability to resist damage.

[0006] Optimize the power management system: To solve the problem of battery exhaustion, you can consider optimizing the power management system, using rechargeable batteries, and equipping with renewable energy equipment such as solar panels or wind power generation devices to extend the battery life of the device. At the same time, you can design an energy recovery system to collect mechanical energy during the movement of the device and convert it into electrical energy for storage for later use.
