The invention discloses a military garbage sorting device based on the Beidou system, and relates to the technical field of garbage sorting. The present invention includes a collection area, a low-temperature plasma waste gas processor and a control room. A plurality of first garbage rooms and two second garbage rooms are fixed in a ring shape on the ground of the collection area, and the plurality of first garbage rooms and the two second garbage rooms are connected to each other. , several first garbage rooms and two second garbage rooms form a closed space on the back side, and a number of underground pools are ring-shaped on the ground of the collection area, and several underground pools are respectively located in several first garbage rooms and two second garbage rooms Inside. In the present invention, by setting up a buried pool, and designing a lift-type detachable garbage compartment in the buried pool for storage of garbage, using a garbage truck matched with the compartment can directly replace the compartment in the buried pool, It facilitates the transfer of garbage, and solves the problems of insufficient efficiency of existing garbage transfer and garbage spillage during transfer.

The invention relates to an optical current sensor and a high-frequency signal measurement system. The optical current sensor comprises an optical sensing part, a polarization maintaining fiber, an insulator and a demodulation module. The optical sensing part, the polarization maintaining fiber and the demodulation module are connected in sequence. The optical sensing part is supported by the insulator. The polarization maintaining fiber locates in an inner cavity of the insulator. The optical sensing part comprises a first sensing fiber ring, a second sensing fiber ring, a first wave plate, a first reflector, a second wave plate, a second reflector and a support, wherein the first wave plate, the first reflector, the second wave plate, the second reflector and the support are all made of nonmetal material. The first sensing fiber ring and the second sensing fiber ring are opposite in current direction. The demodulation module outputs two linearly-polarized beams passing the polarization maintaining fiber and the optical sensing part, the linearly-polarized beams carrying measured current information are returned and received by the polarization maintaining fiber, the beams are operated on the basis of differential induction, and measured current is obtained. The optical current sensor is capable of measuring high-frequency signals, and measurement is higher in accuracy and reliability.

The invention relates to a command transmission method between a spacecraft and a carrier. The command transmission method is implemented based on a command transmission system that comprises a mechanical triggering sub-system and an electrical triggering sub-system. The command transmission method comprises the steps of S1, triggering a first command in the mechanical triggering sub-system, and separately sending the first command to the carrier and the electrical triggering sub-system; and S2, receiving the first command by using the electrical triggering sub-system, and triggering a secondcommand in the electrical triggering sub-system and sending the second command to a sub-system in the spacecraft. High reliable command transmission when the spacecraft and the carrier fly normally orescape during an ascent flying phase by using the way of combining the mechanical triggering sub-system with the electrical triggering sub-system. The method provided by the invention has a redundantdesign of dual-channel, multi-touch and multi-command-center, and completely eradicates the hidden dangers of mistakenly transmission and leaking of the commands.
