This invention relates to a control method for the primary dust collector and dynamic sealing fan of a continuously feeding electric arc furnace, belonging to the field of metallurgical technology. The method includes the following steps: acquiring the power supply and oxygen supply intensity information of the electric arc furnace; setting the initial speed of the primary dust collector and dynamic sealing fan based on the acquired information; acquiring the pressure and temperature information of the preheating duct outlet A, the pressure and temperature information of the dynamic seal B, and the flue gas information; and the control system dynamically adjusting the speed of the primary dust collector and dynamic sealing fan in real time based on this information to achieve adaptive matching of exhaust volume to meet operating conditions during the smelting process. This invention enables the primary dust collector and dynamic sealing fan to adapt to the smelting state of the electric arc furnace, solving the problems of low outlet flue gas temperature, poor sealing effect, and flue gas discharge from the dynamic sealing fan caused by relying on manual experience in traditional horizontal continuous feeding systems.

The invention relates to a configuration method and device for order receiving setting items of online car-hailing drivers, computer equipment and a storage medium. The method comprises the following steps: acquiring multi-dimensional state data of an online car-hailing driver; determining one or more to-be-optimized setting items based on the multi-dimensional state data; generating optimization suggestion information of the order receiving setting item based on the one or more to-be-optimized setting items and the real-time position information of the online car-hailing driver, and sending the optimization suggestion information to terminal equipment of the online car-hailing driver; and in response to an optimization confirmation instruction sent by the terminal equipment of the online car-hailing driver, generating a batch operation instruction for starting or adjusting one or more to-be-optimized setting items, and sending the batch operation instruction to the terminal equipment of the online car-hailing driver, so that the terminal equipment configures the state of each to-be-optimized setting item based on the batch operation instruction. By adopting the method, the order receiving efficiency of the online car-hailing driver can be improved, and the overall operation efficiency and service quality of the online car-hailing platform can be improved.
