This invention discloses an electrically controlled cargo box heating device, method, and mining dump truck, including a heating box, a smoke baffle assembly, an electronic control device, a sealing pipe, an exhaust tailpipe assembly, and a cargo box. The heating box includes a box panel, a smoke baffle slide, an electronic control bracket, an air inlet, an exhaust outlet, and a heating outlet. The electronic control device includes a control unit, an electric push rod, and a lifting cylinder. This invention uses an electronic control system to reverse the engine exhaust during cargo box lifting and lowering, utilizing the high-temperature exhaust gas from the engine to heat the cargo box, achieving waste gas reuse and solving efficiency and safety issues caused by frozen cargo box materials in low-temperature environments. The simple mechanical structure ensures stable reliability, and the electronic control system ensures the orderly operation of each component. Operating the cargo box while disconnecting the heating channel for normal exhaust avoids cargo box blackening and carbon dust dispersion, ensuring a good vehicle appearance and driving environment while heating the cargo box.

The application provides a control method and system for an external circulation working state of a vehicle. The application constructs an evaluation index matrix through three dimensions of the vehicle, i.e. internal environment data and external environment data of the vehicle and positioning information of the vehicle, uniformly and standardly evaluates external air quality, obtains an external circulation evaluation value, and controls a working state of an external circulation device of the vehicle based on the external circulation evaluation value. Through intelligent and multi-dimensional real-time evaluation of the environment around the vehicle, the vehicle can quickly adapt to changes in the internal and external environment of the vehicle, and the air quality in the vehicle and a better driving environment are ensured.

The utility model relates to the technical field of metro silencing, and discloses a metro silencing air duct which comprises an air duct body, an external sound insulation felt, a middle partition plate, internal sound absorption cotton and a grating cover plate. A channel allowing airflow to pass through is arranged in the air duct body, an inlet of the channel is communicated with an air return opening in the bottom of a compartment, and an outlet of the channel is communicated with the interior of the compartment. The middle partition plate is fixed in the air duct in the airflow direction; internal sound-absorbing cotton is arranged on the middle partition plates and air ducts between the middle partition plates; the grating cover plate is arranged at the outlet of the channel, and vent holes are formed in the grating cover plate; and an external sound insulation felt is coated outside the air duct main body. Noise is isolated and eliminated through the silencing air duct, noise in a passenger room of a subway train is reduced, the middle partition plate separates the air duct and is provided with the internal sound absorption cotton, the noise is effectively eliminated by means of the structural characteristics of the middle partition plate and the use of silencing materials, and therefore a good riding environment is provided.
