This invention discloses a method, apparatus, device, and storage medium for testing the charging gun insulation function of an electric vehicle. The method involves immersing the electric vehicle in a predetermined low-temperature environment and charging it to a preset SOC range, causing the temperature of the electric vehicle's power battery to drop below a predetermined low-temperature threshold. While maintaining a physical connection between the charging gun and the electric vehicle, the method monitors the temperature change of the power battery, the output parameters of the charging equipment, and the SOC value of the power battery. When the battery temperature drops to the predetermined low-temperature threshold, the charging gun insulation function is triggered, and key parameters during the function's operation are recorded. Based on the changes in key parameters and the SOC value, the energy source of the charging gun insulation function is determined. This comprehensively verifies the reliability of the function's triggering conditions, temperature control performance, and exit logic, ensuring the normal operation of the electric vehicle's battery thermal management function in low-temperature environments and improving the safety and user experience in cold climates.

This invention proposes a dust suppression system suitable for cold climates, comprising a chemical tank, a water supply pipeline, a mixer, a liquid storage tank, an air compressor, an air storage tank, a foaming tank, and a spraying device. The foaming outlet of the foaming tank is connected to the inlet of the spraying device via a pipeline, and the spraying device is located in the area to be suppressed. The advantages are: the foaming tank uses a low-pressure foaming principle to produce foam, which is then sprayed through spray nozzles to areas prone to dust generation, thereby achieving dust suppression. Simultaneously, since the coal conveyor belt vibrates during operation, it can cause secondary dust generation; the foam can form a continuous "covering film" above the belt, thus providing a continuous dust suppression effect. Due to the poor fluidity of the foam, it will not affect the working environment. By installing a dust detection probe and a spray nozzle at each belt transfer point, individual control of each spray valve is achieved, allowing for optimal dust control with minimal chemical dosage.

This invention relates to the field of agricultural planting technology, and in particular to an irrigation unit for outdoor agricultural planting in cold climates and its usage method. The unit includes an irrigation device, a storage tank, and a conveying pipe A. The storage tank is located at the rear end of the irrigation device, and the conveying pipe A is located at the front end of the irrigation device. A conveying pipe B is fixedly connected to the bottom end of the conveying pipe A. This invention uses an embedded temperature and humidity composite sensor to monitor soil conditions in real time, initiating irrigation only when the soil is water-deficient and the temperature is suitable, avoiding ineffective watering and achieving on-demand water supply, significantly improving water resource utilization efficiency. In low-temperature environments, water injection is automatically prohibited, and a mechanical knocking de-icing mechanism is activated. A servo motor drives a knocking block to periodically impact the outer wall of the extension pipe, generating vibration to shake off ice or prevent icing. In extremely low temperatures, the servo motor adopts an intermittent operation mode, ensuring continuous de-icing while reducing energy consumption, minimizing mechanical wear, and extending equipment lifespan.

This application discloses a vehicle idling control method, device, and vehicle, relating to the field of automotive control technology. The solution includes: when a target vehicle is in extreme temperature conditions and needs to idle, acquiring travel information for the subsequent journey of the target vehicle; the extreme temperature conditions refer to an ambient temperature at the target vehicle that is lower than a first temperature threshold used to determine cold climate conditions, or higher than a second temperature threshold used to determine hot climate conditions; based on the travel information, calculating a first fuel quantity required to complete the subsequent journey to obtain a safe fuel threshold; if the current fuel quantity of the target vehicle is lower than or equal to the safe fuel threshold, controlling the engine to shut off. This solution dynamically calculates the safe fuel quantity according to actual travel needs, replacing a fixed fuel reserve threshold, thereby preventing the vehicle from running out of fuel while ensuring the user can complete the subsequent journey.
