Problems solved by technology

However, if you want to monitor the entire life of the product, you can only use artificial calculations, and the monitored life can only be displayed through the host computer. The mobility is poor, and the monitoring level can only reach the box, and the modules that make up the box cannot be monitored. Life monitoring is carried out, so the monitoring of LED display life has limitations

Abstract

The invention discloses a handheld timing data reader, an LED display screen service life monitoring system and method. The LED display screen service life monitoring system comprises a timer and the handheld timing data reader. The handheld timing data reader is used for being connected with the timer and sending instructions to the timer. The timer is used for receiving the instructions and sending recorded data of modules or box bodies in an LED display screen to the handheld timing data reader, and the data comprise working time which is written into a storage of a microcontroller. The handheld timing data reader is used for displaying data returned by the timer through a TFT liquid crystal display board. The timing data reader can monitor service life of the multiple modules or box bodies in the LED display screen, displaying and timing are separated, and data can be preserved permanently.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a hand-held timing data reader, an LED display screen life monitoring system and a method. Background technique [0002] Digital display technology in modern society is changing with each passing day. As a new type of digital display medium, LED display is widely used in many fields such as news media releases and advertisements due to its vivid color reproduction, high brightness, and long life. It is mainly composed of a display screen and a display control system. The display screen includes a display panel, a power supply, and a structural steel frame. The display panel is spliced ​​by unit modules. The cabinets are combined to form a large screen, and then N cabinets are used to form a large screen; the control system consists of a sending card and a receiving card, and each cabinet is equipped with a receiving card. [0003] With the promotion of LED display applications...
