Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a fault self-checking system for the dynamic shelf display of the LED display screen of a taxi, so as to solve the lateral movement effect of the scrolling screen commonly used in the display of the LED light screen on the top of the taxi, At this time, the fault loss of a single lamp bead is not easy to be identified and detected. Because it is mixed between multiple lamp beads, after the single lamp is overloaded and the filament is turned off, it will cause the jumper bridge of the entire lamp board, skipping the load of the faulty lamp to the lower lamp. body, resulting in continuous and uninterrupted failure to turn off the lights until the entire lamp core is burned. This consumes too much high-precision and high-cost LED lights, and the fault cannot be found in time, which will cause a vicious cascading effect. People often pay attention to the roof lights. Staying on the scrolling instructions on the color screen, the extinguishing of the small lamp beads has a low degree of interference to the large screen, causing people to ignore the effect, resulting in delays in the jumper loss of the roof light screen

Abstract

The invention discloses a fault self-detection system for dynamic frame swinging demonstration of a taxi LED display screen. The fault self-detection system comprises a corner bracket seat, a bottom groove cover plate, a cross beam support plate, a conical top shell cover block, a buckling square box, a lamp bead display screen and a frame plate swinging demonstration mechanism. The lamp bead display screen is matched with the frame plate swinging demonstration mechanism to achieve the effect of easily adjusting a single chip microcomputer reorganized with a rectangular array composing algorithm, so that fault data storage, warning and triggering of a magnetic valve hinge wheel base are facilitated. A red foldable oscillating bar is called to swing, so that a dynamic visual acuity capturing effect is provided for people passing by a taxi; a driver can be conveniently informed that a roof light screen is worn and needs to be repaired immediately; rapid switching is formed for light sensation visual acuity capturing; the timely attention of the line of sight of people is guaranteed; and immediate warning after self-detection of failed lamp beads is facilitated. An oscillating bar rotating stand is supported by 60 degrees, so that the influence of knocking of a taxi roof due to excessive downward swinging on the driving of the driver is avoided, and the effects of protecting the taxi body and effectively and immediately informing people around of the lamp bead damage information are achieved.

Description

Technical field [0001] The invention is a fault self-checking system for a dynamic rack display of a taxi LED display screen, belonging to the field of LED display screens. Background technique [0002] The LED display of the taxi roof light provides the viewing effect for people on foot and in the car, and is convenient for text placement and promotion, and provides convenient advertising services for businesses. It is a subsidiary function of the continuous circulation of large numbers of taxis in the city, and also guarantees the practicality of taxis The shortcomings of current technology common to be optimized include: [0003] The LED light screen on the top of the taxi displays the horizontal movement effect of the commonly used scrolling screen. At this time, the failure and loss of a single lamp bead is not easy to be identified and detected. Due to the inclusion of multiple lamp beads, the single overload will burn out the filament after the lamp is turned off. Causes th...
