The present disclosure provides a flight anti-collision method and apparatus based on electromagnetic field detection of an overhead transmission line. An example method includes: determining whether an overhead transmission line around is an Alternating Current (AC) transmission line or a (Direct Current) DC transmission line; if the overhead transmission line is an AC transmission line, determining a position relationship between an aircraft and the overhead transmission line on the basis of a phase distribution model and an electric field phase and a magnetic field phase measured by a phase detector on the aircraft; if the overhead transmission line around is a DC transmission line, determining the position relationship between the aircraft and the overhead transmission line on the basis of a magnetic field intensity distribution model and the magnetic field intensities collected by magnetic field intensity sensors on the aircraft; and thus controlling the aircraft.

Embodiments of this application provide a flash interface controller and an operation command processing method, and relate to the field of data storage. Programmable first type microcode and second type microcode are introduced to a flash interface controller. The first type microcode can be modified through programming to adapt to a procedure of parsing an operation command of a new protocol, and the second type microcode can be modified through programming to adapt to a flash bus operation required by a new flash interface standard. An operation command can be parsed by only fixing logics of physical modules in the flash interface controller and reading first type microcode and second type microcode that are related to the operation command. Therefore, various protocols and flash interface standards can be adapted to, and flexibility is good.

A hot swappable device includes a port, a firmware module, and an interrupt masking module. The port includes a Peripheral Component Interface express Physical Layer, and the Peripheral Component Interface express Physical Layer includes multiple lanes lanes. The Peripheral Component Interface express Physical Layer detects an analog signal in each of the multiple lanes, when it is detected that an amplitude of an analog signal in one of the multiple lanes is less than a preset threshold, generates an ALOS signal corresponding to the lane, and transmits the ALOS signal to the interrupt masking module. The interrupt masking module generates an ALOS interrupt signal corresponding to the lane and sends the ALOS interrupt signal to the firmware module. If the firmware module receives, in a preset time period, an ALOS interrupt signal corresponding to each lane, the firmware module resets the port.
