Abstract
The utility model relates to a monitoring system for an LED display screen, which comprises sensors, processing units and alarming units connected in sequence. The sensors are installed inside each of the cabinets with display screens to perform real-time monitoring of temperature, humidity, voltage and the like inside the cabinet. Data obtained by monitoring is sent through interfaces back to processing units which process relevant data and send the data back to the host computer which automatically take action according to a predetermined processing method and inform operators with aural and visual alarms. The monitoring system can catch work condition inside each of the LED display screen cabinets, thereby greatly reducing faults caused by excessively high temperature inside the cabinets, condensation or instable voltage and the like, and enabling technical staff to take measures of heat dissipation, moisture removal or other relevant measures to decrease the rate of faults of the LED display screen and prolong the service life of the LED display screen.
