The invention provides a control method for restraining gear shifting circulation of a gearbox, and relates to the technical field of gearbox control. When the gearbox is in the automatic gear shifting mode, the control method is adopted for beginning to count the number of times of gear shifting circulation after gear shifting circulation of the gearbox begins, and when the counting numerical value reaches the initial set threshold value, the control method is adopted for beginning restraining up-shifting of the gearbox. The control method can realize the restraining effect after the gear shifting circulation problem occurs and can be matched with prevention before gear shifting circulation, and therefore the gear shifting circulation problem can be completely solved, vehicles can adapt to complicated driving conditions, and the driving feelings of drivers can be improved.

Automatic cleaning, automatic water supplementing and automatic water draining functions can be achieved, and the self-cleaning evaporation sensor has the advantages of being high in automatic degree, stable and reliable in running and high in measurement accuracy.

The present application discloses an air conditioner control method, device, and air conditioner, wherein the method includes: identifying that the air conditioner is in a low-temperature refrigeration mode; detecting the temperature of the outdoor coil, and identifying the change trend of the temperature of the outdoor coil; According to the changing trend of temperature, adjust the heat exchange area in the outdoor heat exchanger. In this application, after identifying that the air conditioner is in the low-temperature cooling mode, the change trend can be determined based on the outdoor coil temperature, and then the adjustment method of the heat exchange area in the outdoor heat exchanger can be determined according to the change trend of the outdoor coil temperature, and the control The heat exchange area of ​​the outdoor heat exchanger is dynamically adjusted following the temperature change trend of the outdoor coil, no longer relying on the start and stop of the outdoor fan to control the flow of heat, and avoiding the phenomenon of frosting on the surface of the outdoor coil in low-temperature cooling mode , Overcome the technical problem that the air conditioner must frequently start and stop the outdoor fan in the low-temperature cooling mode, and ensure the cooling capacity of the air conditioner.

The invention relates to a water feeding and discharging control method of a leachate anaerobic treatment system. According to the water feeding and discharging control method of the leachate anaerobic treatment system, a PLC system is adopted for sequentially controlling water feeding and discharging of the leachate anaerobic treatment system. The water feeding and discharging control method of the leachate anaerobic treatment system has the advantages that the PLC system is adopted for automatically and sequentially controlling the water feeding and discharging of the leachate anaerobic treatment system, so that the water feeding and discharging control method of the leachate anaerobic treatment system is more intelligent compared with a field manual control method, control is simple, time and labour are saved, efficiency of operators is improved, labour intensity is reduced, and equipment can be automatically monitored and protected in real time.
