This application relates to the field of biscuit production technology, providing a fully asynchronous synchronous control system and method for a biscuit production line. The system includes a data acquisition module, a data processing module, a central control module, and an execution module. Dynamic adaptive adjustment is achieved through a closed-loop control process. The data acquisition module collects real-time data on the speed of each conveyor belt segment, biscuit density, and posture. The data processing module constructs and iteratively optimizes a speed control prediction model based on historical and real-time data to calculate the optimal speed for each segment. The central control module generates segmented acceleration commands for smooth rotation in the cooling section, gradual speed commands for smooth transitions between processes, and dynamic adjustment commands for coordinating the density across the entire line, based on the model output. The execution module responds to the commands with precise speed adjustment. This application achieves global synchronous matching of speed and biscuit density across multiple asynchronous conveyor belts, significantly improving production yield and efficiency while reducing material and energy waste.

This utility model discloses a novel geological exploration drilling device, relating to the field of geological exploration technology. It includes a base with self-locking casters on all four sides of its bottom. A fixing plate is fixedly connected to all four sides of the base's bottom, and each fixing plate has a threaded hole through which a fixing screw is threaded. A handle is fixedly connected to the top of each fixing screw, and the bottom of each fixing screw is conical. A first motor drives a reciprocating screw to rotate, which, combined with a limiting rod, restricts the rotation of the connecting plate, allowing the connecting plate to move precisely up and down axially. Simultaneously, a second motor on the connecting plate drives the drill bit to rotate at high speed. This combination achieves precise control of drilling depth and speed, helping to obtain more accurate geological samples, improving the accuracy of geological exploration, and providing a reliable basis for subsequent geological analysis.
