The two-channel indoor parking guidance screen is the core terminal display device of the intelligent parking guidance system. Specifically developed and designed for the two-channel diversion scenario of parking lots, it is suitable for the parking space guidance needs of exclusive areas such as dual carriageways, cross intersections and dual entrances/exits in garages. The device integrates a high-brightness dual-color LED display module, an industrial-grade intelligent control and stable communication module. It can real-time receive the vacant parking space data of the two channels uploaded by the system, and clearly display it in separate areas in the intuitive form of numbers + direction arrows. It accurately guides car owners to quickly locate the vacant parking spaces in the corresponding channels, effectively solves the problems such as congestion in finding parking spaces and chaotic traffic diversion in the two channels of the garage, greatly improves the vehicle traffic efficiency and the refined utilization rate of parking spaces, and is the preferred device for realizing intelligent diversion guidance of two channels in various large and medium-sized indoor parking lots.
