The present invention discloses an optimization method for an urban drainage scheduling system, which relates to the field of drainage scheduling data analysis, including dividing a two-dimensional surface model into multiple surface cells according to the average surface slope, generating a three-dimensional pipe network block by combining the two-dimensional position information of a closed area with the average depth data of the pipe segment in the corresponding node line segment according to the node distribution position data and the corresponding connected nodes, and calculating the flow of the three-dimensional pipe network block; calculating the vertical exchange flow between the surface cells and multiple three-dimensional pipe network blocks; dynamically adjusting the two-dimensional surface model to the surface cell division, coupling the one-dimensional pipe network model and the two-dimensional surface model, and generating a coupling model; inputting sensor acquisition data into the coupling model, and deriving the data results of the coupling model for drainage scheduling. The present invention provides a scientific reference for executing a reasonable drainage scheduling operation strategy, stops losses in time, prevents and controls in advance, and ensures property safety.

The invention relates to the technical field of financial data management, in particular to a cross-channel marketing financial data real-time collection and risk early warning method. According to the technical scheme, the method comprises the following steps: obtaining marketing expenditure and income channels of a current product, and obtaining financial data of the current product; a revenue and expenditure relation model is constructed through marketing expenditure and revenue financial data of the current product. And calculating and obtaining an optimal marketing expenditure channel set through the income and expenditure relation model of each time period. And judging whether the total marketing income and expenditure ratio is greater than a preset minimum profit ratio, if so, not sending an alarm signal, and if not, sending an alarm signal. According to the method, the expenditure utility coefficient can be extracted through construction of the income and expenditure relation model, then the optimal marketing expenditure channel set is constructed, and various optimal marketing expenditure channels are screened out, so that targeted selection and adjustment of the marketing expenditure channels can be performed, and invested funds are optimized and benefits are maximized.

This invention discloses a gas ball valve with automatic shut-off function for gas leak detection, relating to the field of gas ball valves. Addressing the problems of existing gas ball valves having limited functionality, lacking gas leak detection, failing to provide timely feedback on gas leaks, and exhibiting low safety, this invention proposes the following solution: It includes a ball valve protective tube body, within which a valve ball is disposed. A first valve stem is mounted on the top of the valve ball. A detection frame is mounted on the side of the first valve stem away from the valve ball. A second valve stem is mounted on the side of the detection frame away from the first valve stem. A rotating handle is mounted on the side of the second valve stem away from the detection frame. A threaded rotating rod is mounted inside the valve ball body. This invention features a novel structure, is easy to use, provides thorough gas leak detection with high accuracy and good detection effect, and promptly shuts off the gas ball valve upon gas leak, thus improving the safety of the gas ball valve.

This invention provides a continuous conveying capping device for beverage bottle caps and its capping qualification rate monitoring system, relating to the field of machining. The invention includes a housing, a display screen, a packaging feeding structure, a pushing structure, a packaging conveying structure, a first limiting conveying structure, a second limiting conveying structure, a bottle cap conveying structure, a bottle cap conveying diversion structure, a bottle cap feeding structure, an adhesive coating structure, and a camera. Multiple clamping structures are fixedly installed on the outer side of the bottle cap conveying structure. These clamping structures convert the pushing and pulling forces controlled by the telescopic hydraulic cylinders to the force required to detect the qualified capping of the outer packaging, enabling timely detection of the processing qualification rate. When consecutive processing failures occur, workers can promptly stop losses and reduce the cost of the conveying capping equipment.
