The present application relates to the technical field of online car-hailing risk control, and particularly relates to a method for implementing an online car-hailing pick-up and drop-off abnormality risk control dynamic rule engine based on flink CEP. In the online car-hailing service, after a passenger issues an order on a mobile phone, the driver is affected by external environmental factors, vehicle condition factors, other human factors and complex environments during the process of picking up and dropping off the passenger, which may result in a variety of abnormal situations such as pick-up timeout, driver driving in the opposite direction, driver not moving and the like. A related risk control system is established in each service system. The present application uses mysql to dynamically load rules to ensure the dynamic scalability of the rules, and uses flink CEP to calculate the rules to ensure the timeliness and accuracy of the calculation results. The overall scheme supports the timeliness and dynamic scalability requirements of abnormal indicators in the risk control system under the premise of not stopping service when the rules are changed.

This utility model belongs to the technical field of chemical analysis and detection devices, specifically relating to an auxiliary device for a bottle-mouth pipette. It includes, from bottom to top, an annular plug, an angle adjustment assembly, and a second annular plug connected to the adapter port of the bottle-mouth pipette. The angle adjustment assembly includes a support ring plate, an elastic rubber ring, and an angle adjustment ring plate. The support ring plate and the angle adjustment ring plate are connected by a coaxially arranged elastic rubber ring. The annular plug is connected to the bottom of the support ring plate, and the second annular plug is connected to the upper surface of the angle adjustment ring plate. The edges of the support ring plate and the angle adjustment ring plate are bonded together with matching Velcro. This utility model has a simple structure, low cost, and is easy and controllable to operate. It can stably and conveniently connect a bottle-mouth pipette to a reagent bottle, especially a conical flask, and facilitates adjustment of the insertion angle of the pipette tip in the reagent bottle, preventing air bubbles from forming during aspiration due to excessively low liquid levels in the reagent bottle.

This utility model discloses a high-pressure microenvironment vapor deposition device, relating to the field of vapor deposition technology. It includes a fixed structure, with a sample structure mounted at the bottom of its inner cavity. The fixed structure includes a base, and a sealing cover is mounted at the bottom of the base. A sealing cover door is rotatably connected to one side of the outer wall of the sealing cover. Air inlets are provided on both sides of the outer wall of the sealing cover. Through the coordinated operation of a stepper motor, a transmission rod, and a rotating rod, the opening and closing of the sealing plug is precisely controlled, thereby controlling the opening and closing of the nozzle of the first spray tube and thus precisely controlling the thin film processing flow. Furthermore, a high-pressure automatic valve and specific structure in the second sealing tank can automatically open the nozzle to precisely coat the defective area upon detection of coating defects. Combined with real-time infrared thermal imaging monitoring, compared to traditional devices, this achieves intelligent and controllable operation of thin film processing, not only ensuring the quality of film coverage but also efficiently repairing defects and improving the overall processing effect.
