Abstract

The invention discloses a remote programmable logic controller (PLC) automatic control system for a light-emitting diode (LED) display screen. The remote PLC automatic control system comprises a PLC control module, a display screen control module, a power distribution cabinet, a PLC, a power supply module, a state monitoring module and an LED display screen, wherein the PLC and the power supply module are integrated in the power distribution cabinet; the PLC control module is used for sending instructions for starting and monitoring the LED display screen to the PLC; the PLC is used for controlling the power supply module to supply power to the LED display screen, controlling the state monitoring module to monitor state data of the LED display screen and transmitting the state data acquired by the state monitoring module to the PLC control module; and the display screen control module is connected with the PLC control module and is used for displaying an alarm and taking correspondingemergency measures when the state data of the LED display screen are abnormal. By the remote control system, the LED display screen can be remotely monitored and controlled conveniently without in-site control of personnel, and the display screen can be safely used.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a remote PLC automatic control system for LED display screens. Background technique [0002] With the continuous development of the LED display industry, people have higher and higher requirements for the LED display power supply system. The traditional power distribution power supply system is mainly based on manual control of the guillotine switch, and some are equipped with a simple timer to achieve simple Automatic timing control, this kind of control can't meet the requirements of modern automatic control and emergency automatic control of the emergency situation of the display screen, such as: time-sharing power-on of the display screen, automatic brightness adjustment, high-temperature automatic power-off protection, fire alarm Monitoring and power failure protection, etc. [0003] Chinese utility model patent CN201075249Y discloses a remote monitoring system for LED di...
