The invention provides an optical fiber positioner and a positioning method thereof, the optical fiber positioner comprises a mechanical main body, an optical fiber assembly, a rotating assembly and a lens assembly, the mechanical main body is a whole composed of a hollow cylinder, an annular baffle plate and an annular platform provided with a preset number of grooves; the optical fiber assembly comprises an optical fiber mechanical part and an optical fiber, and the optical fiber assembly at least has an external shape complementary to the shape of the inner wall of the hollow cylinder; the rotating assembly comprises a rotating handle and at least one pressing block, and the optical fiber assembly at least has an external shape complementary to the shape of the pressing block; the lens assembly includes a mechanical cylinder and a lens. Dual positioning of the optical fiber assembly is realized through the inner wall of the mechanical main body and the annular baffle plate, and the optical fiber assembly is further fixed between the pressing block and the annular baffle plate to realize accurate positioning of the optical fiber assembly; the rotating handle rotates to drive the pressing block to move, and rapid installation and positioning of the optical fiber assembly are achieved.

The utility model relates to a car logo electric lifting device, especially a car logo electric lifting device. A car logo electric lifting device includes a car logo unit, further includes the sliding mechanism for connecting the car logo unit and driving car logo unit moves up and down, and the sliding mechanism is connected on the guide rail, and its bottom is connected with the driver assembly. The car logo electric lifting device has the anti -theft function and the pedestrian protection function, and the whole is through the guide rail, slider assembly and driver and is composed, and the space is small in structure, and the car logo can quickly retreat, thereby realizes car logo theftproof and pedestrian protection function.

The invention relates to the technical field of software, and provides a front-end publishing method, electronic equipment and a storage medium. The method comprises the following steps of: setting an independent access domain name for an HTML (Hypertext Markup Language) of an engineering static file, and setting a material static resource and other engineering static resources as a unified access domain name; continuous integration / continuous deployment access transformation of the project is carried out; and accessing an automatic publishing platform, and carrying out visual configuration and publishing on required functions. According to the technical scheme, the publishing and packaging product at the front end is transformed, a core HTML for WEB version management is independently managed, resource sharing of other static resource files is achieved, and an incremental publishing and configurable efficient caching strategy scheme is achieved; and through a CICD deployment platform, rapid version rollback is supported while the difference of the packaging environment is flattened. The operation and maintenance cost is greatly reduced, and meanwhile high efficiency is guaranteed.

This invention relates to an automatic software update method based on an in-vehicle embedded operating system, belonging to the field of computer software technology. It solves the problem that existing methods cannot simultaneously achieve reliable system startup and flexible, secure automatic software updates. The method includes: partitioning the physical disk into a system root partition, a user data partition, and an OverlayFS working partition; automatically entering safe mode by detecting kernel boot parameters, mounting the system root partition as read-only, and mounting specified directories as read-write overlays based on the OverlayFS file system and whitelist configuration files; dynamically switching the safe mode on and off via system services and command lines; upon detecting an external update device, entering maintenance mode, performing security verification on the update package from the external update device, and then performing an atomic update operation on the user data partition. This achieves both reliable operating system startup and flexible automatic software updates.
