This invention discloses a low-temperature sterile nanofiltration membrane treatment process for high-quality direct drinking water, mainly comprising: tap water, which passes through a delivery pump and a precision filter, and enters a nitrogen-sealed inlet tank; a vacuum system expels air from the nanofiltration (NF) membrane treatment system; a nitrogen generation system produces nitrogen gas with 99.5% purity, which is independently controlled by valves to replenish nitrogen gas to the nitrogen-sealed inlet tank, the NF membrane treatment system, and the NF membrane direct drinking water tank; after the nitrogen purity in the NF membrane treatment system meets the standard, the NF membrane treatment system is turned on, and the NF membrane permeate enters the NF membrane direct drinking water tank, passes through a nano-silver sterilization device, and is then transported to the end user by an external pump; the NF membrane concentrate is discharged into a rainwater well or a sewage well through an NF membrane concentrate discharge pipe. The high-quality direct drinking water nanofiltration membrane treatment process provided by this invention has the following advantages: the process is safe and reliable, improves the taste of NF membrane direct drinking water, reduces NF membrane fouling, and is easy to maintain.

The application discloses a kind of electric engineering machinery cooling system control method and cooling system, system includes electric drive heat dissipation system, integrated air conditioning system and battery cooling system;Method includes: obtaining the monitoring data of cooling system, according to the monitoring data judges cab refrigeration demand degree and battery pack BMS cooling request mode;According to cab refrigeration demand degree and battery pack BMS cooling request mode, execute corresponding refrigeration instruction;When cab refrigeration demand degree or battery pack BMS cooling request mode changes, end operation.Obtain the monitoring data of cooling system, accurately determine cab refrigeration demand degree and battery pack BMS cooling request mode, adopt the mode of double electronic fan independent control to realize condenser and radiator accurate heat dissipation, adaptive adjustment compressor speed and electronic fan speed, to effectively realize the reasonable cold distribution of cab and battery pack by low energy consumption, guarantee ride comfort and safety.

The application discloses a time-varying path planning method, comprising the following steps: S1, determining path initial data of a mechanical arm, including a starting point x start and a termination point x end of the path; S2, acquiring feature information of an obstacle at a current time; S3, judging whether obstacle avoidance is needed; when obstacle avoidance is not needed, generating a path, and ending path planning; when obstacle avoidance is needed, obtaining a center point O0 of the path without obstacle avoidance in an obstacle space, and entering step S4; S4, determining a fuzzy center C of the obstacle according to feature points of the obstacle, and determining a direction of the path bypassing the obstacle according to the fuzzy center C of the obstacle and the path initial data of the mechanical arm; S5, determining feature points of the path according to the center point O0 and the direction of the path bypassing the obstacle; S6, generating the path at the current time according to the feature points of the path; and S7, returning to step S2 at a next time. The application can effectively improve path planning efficiency, adjust a smooth path in real time, and is particularly suitable for global dynamic obstacle avoidance of moving objects such as a snake-shaped mechanical arm.
