A control method, a control system, and a non-transient computer-readable storage medium are provided. The control method is applicable to a pumping station comprising one or more pumps. The method may include: comparing an inflow rate of the pumping station with a flow rate for optimal energy consumption of the pumping station; determining, based on whether the inflow rate of the pumping station is greater than or equal to, or less than or equal to, the flow rate for optimal energy consumption of the pumping station, a corresponding constraint that indicates whether a target outflow rate of the pumping station is to be greater than or equal to, or less than or equal to, the flow rate for optimal energy consumption of the pumping station; and setting a target outflow rate that meets the constraint, for constant flow rate control of the pumping station.

The invention relates to the technical field of fund transaction data processing, in particular to a security investment fund transaction data processing method and system, and the method comprises the following steps: capturing external original information, and completely storing the external original information in an undetermined information pool without content screening; identifying fund transaction; analyzing statistical characteristics of fund outflow behaviors; judging whether the fund transaction is in a collaborative low-speed outflow state or not; if it is judged that the state is the collaborative slow outflow state, first-level early warning is generated; when the total fund outflow rate of the fund exceeds a first preset threshold value in a preset first time window, extracting corresponding fund outflow information, and querying whether first-level early warning exists or not; if yes, the fund outflow information and the first-level early warning are combined to form an event record, and the potential external inducement information is attached to the event record to form a composite abnormal event report. Cooperative low-speed fund outflow caused by hidden external information can be effectively identified and early warned.

The invention relates to a multi-thread traffic control method under an MQTT protocol and communication equipment, relates to the technical field of Internet of Things, and solves the problem that traffic control is unreliable in a network instability or high-concurrency scene in a traditional scheme. The method comprises the following steps: determining the token generation rate of each thread group according to the weight of each thread group and the real-time total bandwidth of a network; according to the token generation rate of each thread group, determining the leaky bucket capacity of the thread group; and setting the leaky bucket outflow rate of each thread group to be the same as the token generation rate of the thread group. According to the invention, fine control of multi-thread flow is realized, the bandwidth utilization rate is improved, and the probability of system congestion collapse is reduced.

The utility model discloses an oscillating screw drill movable valve assembly with a flow switching function, which relates to the field of oil and gas drilling downhole tools and comprises an overflowing component and a flow adjusting part. The overflowing assembly comprises a movable valve plate, a flow dividing seat and a hollow anti-falling rod which are sequentially arranged from top to bottom and are axially through, an eccentric hole for drilling fluid to flow in is formed in the movable valve plate, and a center hole and a plurality of flow dividing holes located in the periphery of the center hole are formed in the flow dividing seat; the flow adjusting piece is detachably arranged between the center hole and the hollow anti-falling rod and comprises a center spray pipe and a center plug which are alternatively arranged so as to be used for changing the communication state between the center hole and the hollow anti-falling rod, and then the outflow flow of the flow dividing holes is adjusted. The drilling fluid flow can be conveniently and rapidly adjusted, the whole anti-falling rod does not need to be replaced, and the replacement efficiency is improved.

This application discloses a flow control method, apparatus, and medium for a spray device. The flow control method includes setting a target outflow rate at the outlet of the spray device; determining a predetermined liquid level within the spray device; introducing at least two chemical solutions into the inlet of the spray device to mix them within the device, forming a mixture, with the mixture being discharged from the outlet simultaneously with the inlet; and controlling the inlet flow rate such that when the inlet inflow time is a first predetermined time, the liquid level within the spray device increases to the predetermined level, and the inlet flow rate equals the target outflow rate, and the outlet flow rate is close to or equal to the target outflow rate, so that the mixing time of the mixture within the spray device is a second predetermined time. This application enables the mixture to mix within the spray device for a second predetermined time, which helps achieve better substrate treatment results when the mixture is supplied to the substrate surface.

This invention provides a wastewater pipeline network monitoring method and a computer-readable storage medium. The wastewater pipeline network monitoring method includes S1. a flow acquisition step and S2. a synchronous analysis step, analyzing the wastewater inflow Q of branch segment 1. in Wastewater outflow rate Q out The time synchronization between them, the optimal lag time ΔT; S3. Flow loss calculation steps, to make the sewage inflow Q in With wastewater outflow Q out Synchronize, and then calculate the flow loss Q based on the difference between the two time series. s =Q in -Q out S4. Fault confirmation steps, if the traffic loss Q s If the branch section is located outside the predetermined standard range, there may be a potential fault. This sewage pipe network monitoring method can detect potential seepage conditions in branch section 1, such as ruptures or gaps, and can also monitor the overall patency of the pipe in branch section 1. It facilitates the installation and maintenance of the monitoring system, enabling non-contact monitoring and maintenance, and allows for real-time detection and reporting, thus improving response speed.
