Abstract: An automatic uncoupled charging device includes a control system, a power system, a charging system, and an auxiliary system. The control system is equipped with a programmable circuit to control a screw speed. Explosives are charged into a container through manual handling or flowing from a mixed explosive vehicle. Explosive bags with different diameters are installed at the bottom of a discharge port. The device is set to start with one click, and the screw drives the explosive into the bag, achieving uncoupled charging. An automatic uncoupled charging method applying to the automatic uncoupled charging device not only reduces labor intensity, achieves fast charging, improves labor efficiency, but also achieves the goal of “mechanization reducing personnel”, further advancing towards the essential safety of blasting construction.

Abstract: The present disclosure relates to code scanning methods based on vehicle-mounted cameras. One example method includes collecting a first image by using a vehicle-mounted camera, parsing a target encoding pattern included in the first image, and when no parsing information is obtained, collecting, based on image data obtained by the vehicle-mounted camera, another image that is close to the first image in a time relationship for parsing to attempt to obtain parsing information in the target encoding pattern.

Abstract: An information recording method includes obtaining image information; displaying prompt information on a head-up display based on the image information, where the prompt information is used to guide a user to record facial information; and obtaining the facial information.

Abstract: An optimization method for a directional preparation technique and efficient use of semi-coke for blast furnace injection. Firstly, the volatile and the ash content of target semi-coke are preset, and then the volatile and the ash removal percentages of a raw coal are calculated; after ash removal, several sets of dry distillation carbonization temperatures and carbonization times are obtained according to the volatile removal percentage, and the relationships between a combustion rate, abrasiveness, explosiveness and jet flow property and the carbonization temperature are respectively established to obtain the optimal actual carbonization temperature; and semi-coke for blast furnace injection is obtained at an actual carbonization temperature.
