Crane windproof control system based on prediction model

Abstract

The invention discloses a crane windproof control system based on a prediction model. The crane windproof control system comprises a wind-speed prediction processor, a controller, a crane windproof anchoring device, a crane cart traveling mechanism and a wind speed sensor, wherein the wind speed sensor is used for detecting the wind speed of a wind force born by a crane cart; the wind speed prediction processor is used for processing a detection signal inputted by the wind speed sensor according to the wind speed prediction model; the controller controls the crane windproof anchoring device and the crane cart traveling mechanism according to a processing result signal u inputted by the wind speed prediction processor. According to the crane windproof control system, wind pressure which can damage a crane can be prejudged by the wind speed prediction processor according to a minimal wind speed and a wind speed variation rate, and then the crane windproof anchoring device can be controlled by the controller to open in advance, the crane cart traveling mechanism is closed, so that the problem of crane damage caused by incapability of enabling a crane windproof anchoring device to work in time of a traditional crane windproof control system can be solved, and the windproof effect is good.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a windproof control system of a crane. Background technique [0002] Cranes operating on the track in the open air are generally affected by natural wind. When the wind is greater than the specified value, the crane should stop working. When a crane in a non-working state is hit by a strong wind, it may overcome the braking force of the brake of the traveling mechanism of the cart and slide. This uncontrolled slide will cause the crane to cause a strong impact at the end of the track so that the whole body will tip over, causing serious losses. Therefore, cranes running on open tracks, such as gantry cranes, loading and unloading bridges, tower cranes and gantry cranes, should be equipped with windproof anchoring devices. [0003] The control systems of the windproof anchoring devices of existing cranes are based on the fact that they only function when the wind force increases ...
