Abandoned LED display screens are transformed into epidemic prevention early warning systems to help precise prevention and control of highways

Before the upgrade, the on-site epidemic prevention and control early warning system only relied on broadcast prompts from wireless broadcast transmitters and wireless speakers in the outer square. When the toll station crossing encountered peak traffic flow, inspectors were prone to be unable to hear or remember vehicle information. The Xianju Toll Center renovated the discarded TV sets and LED displays at the station. Through video transmission lines, relevant information such as vehicle license plates, entrance toll stations, and exit lanes from medium- and high-risk areas were directly projected in the form of text onto the LED display under the epidemic prevention greenhouse at the stuck point, reminding epidemic prevention inspectors to conduct accurate inspections of risk vehicles to ensure that no vehicle or person is missed.
