The invention discloses a ship rope production scheduling method and scheduling system, and relates to the technical field of ship rope production, a production progress monitoring module can accurately master the production rate change per hour and generate an instant production progress index Pi by monitoring the equipment state and the production batch progress in real time. The data supports the real-time adjustment of a production plan, and ensures that the resource allocation and time arrangement are more reasonable in the production process, thereby improving the production efficiency and reducing the delay. Meanwhile, the system can predict the future production trend based on the change of the production schedule index, thereby facilitating the adjustment of the production strategy and avoiding the phenomenon of production bottleneck or shutdown. And the consumption analysis and feature extraction module can extract consumption parameters according to the current production progress and the production progress index, and accurately monitor the material consumption. By analyzing and extracting consumption characteristics, the system can identify whether an abnormal material consumption condition exists in the production process, so that potential production problems can be found in advance.

The invention relates to a photochromic coating. The photochromic coating comprises a component A and a component B, the component A is prepared from the following raw materials: a hydroxyl-containing acrylate copolymer and a photochromic dye; the hydroxyl-containing acrylate copolymer is prepared from the following raw materials: a copolymer monomer, wherein the copolymer monomer comprises an acrylate monomer and a styrene monomer; the equivalence ratio of a hydroxyl group of the hydroxyl-containing acrylate copolymer to an isocyanate group of the polyisocyanate curing agent is 1: (0.9-1.1). By optimizing the formula of the photochromic coating, the color changing performance and stability are remarkably improved, and the haze is effectively controlled.

This utility model relates to the field of oil leakage detection technology, and in particular to an oil leakage detection device for a lubricating oil air-cooled radiator filter element. It includes a filter element body installed on the circulating oil pipe of the radiator body, an oil pump for controlling the circulation of the circulating oil pipe on the circulating oil pipe, a collection cylinder located outside the filter element body, at least two proximity switches cooperating with a sensing element, and a controller. The upper end of the collection cylinder is open for collecting leaked oil from the filter element body. A buoyancy rod is slidably connected inside the collection cylinder via a connecting pipe, and a buoyancy ball is connected to the lower end of the buoyancy rod. This utility model utilizes the buoyancy of the buoyancy ball to drive the sensing element to contact the proximity switch at the corresponding position, thereby realizing a multi-position detection and graded early warning mechanism. This avoids misoperation or overreaction caused by single threshold detection, provides operators with more reasonable response time and decision-making basis, and reduces the workload of on-site personnel inspection.
