The invention relates to a
bus-
system LED display system point-by-point fault detection method and the application thereof. The method is based on a parallel
bus-
system LED
lighting control system. The system is composed of an upper computer, an LED controller and a plurality of LED lamps which are connected in parallel and controlled by the LED controller. The LED controller is connected with the upper computer through an
optical fiber or a network cable. The LED controller is composed of a TCP / IP communication module, a center processor, an
information storage module (which is selectable) and a first communication module. Each
LED lamp is composed of a second communication module, a processor and data storage module, a display monitoring module and a display module, wherein the second communication module of the
LED lamp is connected with the first communication module of the LED controller through an address writing line and a communication
bus. The system has the functions of remote monitoring, fault detection, fault feedback, automatic fault shielding, brightness adjustment, automatic encoding and the like, and managers can grasp system working conditions immediately; due to the fact that the system has the automatic fault shielding function, fault points are in the perfectly-black state, and damage caused by
color loss, flashing and other phenomena on the whole picture vision is avoided.
