Problems solved by technology
[0004]
1. The STS cart is an open-loop control mode, with low control precision and easy to be disturbed by the outside world
The inconsistency between the actual walking speed of the STS cart and the given walking speed of the open-loop control mode cannot be compensated
[0005]
2. When the STS cart is affected by the strong wind, it is impossible to adjust and control the walking of the STS cart
[0006] 3. When the STS cart is affected by the strong wind, the speed of the traveling cart is too fast, which may easily cause the brake of the cart to fail, unable to stop safely and reliably, resulting in safety accidents

The invention provides an STS cart gust-proof control system, wherein a speed increasing gear is connected onto a wheel axle of a driven wheel, and is connected with a speed encoder; a frequency converter is connected with a speed encoder and a walking motor; "cart handle given speed" and "cart handle given maximum speed" are given by a cart handle operation controller, or a strong wind operationswitch command is utilized, and PLC is used for defining the maximum speed of the cart walking given speed as the 20% of the cart handle given maximum speed, then the frequency is used for operating the cart according to the cart walking given speed; and the frequency is used for compensating the deviation value of the cart walking given speed and the cart walking real-time speed in a real time manner output by the PLC controller; an anemograph sensor is used for acquiring and inputting real-time wind speed to the PLC controller, and the PLC controller is used for calculating out the "real-time wind speed giving cart walking speed". The entire control system can realize automatic control and manual control, as well as real-time fault detection function, and can guarantee that the STS cartaffected by gust can run safely, reliably and effectively.
Description
technical field [0001] The invention relates to a windproof control system for an STS cart (hereinafter referred to as the STS cart) of a shoreside container crane, in particular to an STS cart anti-gust control system. Background technique [0002] Such as Figure 6 As shown, in the prior art, the STS cart of the quayside container crane is equipped with protection devices such as wheel clamps to prevent strong winds in a static state, and the STS cart travel control method is to first open the driving wheel brake of the STS cart, The open-loop control mode of excitation driving the traveling motor of the STS cart is established after the protection device against strong wind such as the wheel gripper, and the STS cart is easily disturbed by the outside world when traveling. The actual traveling speed of the STS cart is different from that of the open-loop control mode. The given walking speed is inconsistent and cannot be compensated. When the STS cart is running, it cann...
