Intelligent early warning windproof system of portal crane

The invention discloses an intelligent early-warning windproof system of a portal crane, and belongs to the technical field of windproof early warning of cranes. The system comprises a logic control module, a network module, a man-machine interaction module, and a weather forecast monitoring module, an alarm module, a load detection module, a wind speed detection module and a crane windproof and antiskid module which are connected with the logic control module, alarm information is sent to inform safety management personnel so as to take windproof prevention measures in advance; the logic control module monitors the wind speed value collected by the wind speed detection module in real time, when the wind speed exceeds an alarm threshold value for a certain time, alarm information is sent to inform safety management personnel, and the load detection module displays the state of the crane and executes the windproof and antiskid device of the crane. According to the invention, wind prevention early warning and o
