The invention belongs to the technical field of sea detection radar, and discloses a marine and ionosphere integrated detection high-frequency radar system and a control method thereof. Controller, integrated signal generator, ionospheric detection subsystem and ocean information detection subsystem. According to the principle of high-frequency ground wave radar and ionospheric vertical measuring instrument, the present invention designs a new type of ocean-ionospheric information integrated detection high-frequency radar system to realize the simultaneous acquisition of ocean-ionospheric information, which is the physical operation law of the near-earth ocean-atmosphere And scientific research such as principle analysis provides data support. At the same time, the present invention realizes the synchronous acquisition of ionospheric vertical survey and ocean information by designing a unified timing controller and designing mutually synchronized waveform parameters, avoiding mutual interference between the two, and ensuring the ionospheric vertical survey and ocean information acquisition. They do not interfere with each other, and can obtain ionospheric information and ocean information synchronously.

The invention discloses a conference synchronization method. A plurality of receiving terminals receive conference files transmitted by a sending terminal, and the receiving terminals encrypt the conference files to obtain encrypted files; the receiving terminal sends encrypted feedback information to the sending terminal; After receiving the encrypted feedback information from the terminal, the decrypted data is transmitted to the receiving terminal, and the receiving terminal decrypts the encrypted file according to the decrypted data to obtain the conference file; after receiving the conference file, multiple receiving terminals encrypt it and wait for the decrypted data of the sending terminal. , so that multiple receiving terminals can download and transmit conference files first, and after receiving the encrypted feedback information, the sending terminal sends decrypted data to multiple receiving terminals synchronously, so that multiple receiving terminals decrypt their encrypted files synchronously, so that The participants who hold the receiving terminal can obtain the access rights of the conference files synchronously, so as to realize the synchronous acquisition of the conference files.

The invention discloses a grain aflatoxin and external defect high-throughput sorting machine belonging to the field of sorting; wherein a photoelectric box is installed at the rear of the main frame, and a high-throughput 180-degree rotating high-throughput box is installed in the middle of the photoelectric box. On-line rejecting device, there are two front and rear material boxes under the high-throughput on-line rejecting device; a horizontal high-speed belt set is installed in front of the high-throughput on-line rejecting device, and sliding belts are arranged above the front end of the high-throughput on-line rejecting device in sequence from bottom to top. Groove, adjustable hopper and feeding box, the lower end of the adjustable hopper is fixedly connected to the vibrating feeder; a fluorescent detection device for toxic raw materials is installed directly above the high-speed belt group; a photoelectric detector installed outside the rear exit of the high-speed belt group Raw material external quality sorting device inside the box. The invention can not only detect toxin-containing grains, but also simultaneously remove damaged and inferior grains and sundries. It has advantages that traditional color sorters cannot match, and breaks through the problem of high-throughput real-time online sorting of toxic grains.
