Abstract: A molding apparatus, a cigarette filter rod and a preparation method thereof are disclosed. The molding apparatus comprises a single-screw extrusion system and a cooling setting system. The single-screw extrusion system comprises a feeder and an extruder. The feeder is arranged on the extruder. The extruder comprises a cylinder. A heater is arranged outside the cylinder. A screw is arranged inside the cylinder, and a mouth mold is arranged at one end of the cylinder. The cooling setting system comprises a round tube and a cooler. The cooler (6) is arranged outside the round tube. One end of the round tube is butted with the mouth mold of the extruder; and multiple groups of grooves are formed on threads of the head of the screw.

Abstract: Provided is a control method, an electronic device and a storage medium. The method comprises: when determining that a yarn spindle transported on a transport channel enters a detection area, detecting the yarn spindle located in the detection area to obtain an appearance feature of the detected yarn spindle; wherein the transport channel is a channel for transporting yarn spindles in an automatic packaging workshop; and the detection area is at least a partial area on the transport channel; when the appearance feature of the detected yarn spindle does not meet a first preset requirement, determining the yarn spindle with the appearance feature not meeting the first preset requirement as a target yarn spindle; and detecting a physical attribute feature of the target yarn spindle.

Abstract: A monitoring system based on a digital converter station includes a first monitoring terminal deployed at a first-level monitoring side, a second monitoring terminal deployed at a second-level monitoring side, and a third monitoring terminal deployed at a third-level monitoring side; the monitoring terminal at each level includes a communication module, a human-machine interaction module, a device status monitoring module, a device alarm management module, a video fusion processing module, and a data transmission adjustment and control module.

Abstract: A method including establishing a communication connection of a first Internet of Things device with a trusted device; acquiring a first communication key, the first communication key being provided to the first Internet of Things device and/or a second Internet of Things device via the trusted device; performing, on the basis of the first communication key, encrypted communication with the second Internet of Things device, thereby ensuring that the first Internet of Things device and the second Internet of Things device are capable of acquiring the first communication key, and performing encrypted communication on the basis of the first communication key, thus enhancing the security and reliability of communication between the first Internet of Things device and the second Internet of Things device.

Abstract: Identity authentication method, system, and computing device are disclosed. The method includes: an identity authentication method is provided, which includes: a first device establishing a communication connection with a second device, and obtaining encrypted information through the Internet, where the first device is a device that is allowed to access the Internet, and the second device is a device that is not allowed to access the Internet; the first device encrypting identity information of an account that is logged into the second device by using the encrypted information, and sending the encrypted identity information to the second device; and the first device receiving a verification result that is returned by the second device, wherein the second device verifies the encrypted identity information based on verification information.

Abstract: The present disclosure provides a shift register unit, a gate electrode drive circuit and a display apparatus, which relates to a technical field of display. The shift register unit includes an input reset module, a pull up module, a control module and a pull down module. By inputting a high level into the second signal input end of the input reset module in the touch scan to maintain the level at the pull up control node, the electrical leak effects at the pull up control node may be avoided efficiently. In this way, the defects of insufficient charging rate of the row pixels may be avoided and the dark lines or bad bright lines may be suppressed.
