The application belongs to the signal reading part in the circuit system, and relates to a digital signal driving circuit and a driving method with multi-channel input and single-channel output. The driving circuit comprises an enabling pulse generating circuit, a time sequence generating circuit and m signal transmission circuits. The enabling pulse generating circuit has one clock signal input end, one enabling pulse signal input end and n column-level circuit output switch control signal output ends. The time sequence generating circuit has k column-level circuit output switch control signal input ends and k signal transmission control time sequence output ends. Each signal transmission circuit has n column-level circuit signal input ends, n column-level circuit output switch control signal input ends, k signal transmission control time sequence input ends and one single-tap data output end. In one signal transmission circuit, n columns of signals are divided into k sections for driving respectively, and each section has j columns of reading circuits, so that multi-channel input and single-channel output of single-tap signal transmission from the column-level circuit are realized.

This invention discloses an adaptive sliding mode control method for tower cranes based on an improved fruit fly optimization algorithm, comprising the following steps: Step 1): Designing an extended state observer to observe the load swing angle state; Step 2): Designing an adaptive sliding mode controller, feeding back the observed swing angle state to the adaptive sliding mode controller, which will enable the trolley to be precisely positioned while suppressing load swing angle oscillation; Step 3): Optimizing the parameters of the adaptive sliding mode controller through an improved fruit fly optimization algorithm, thereby improving the controller's control effect. This invention uses a combination of a linear extended observer and an adaptive sliding mode controller, which has the advantages of easy swing angle observation, simple physical implementation of the controller, and good control effect; in terms of parameter tuning, an improved fruit fly algorithm is used to strengthen the cooperation among fruit flies, avoid getting trapped in local optima, and improve the controller's control effect.
