The invention discloses a solar radio storm detection method based on the decrease of the carrier-to-noise ratio of GPS / BDS. The method utilizes the influence of the solar radio storm on the carrier-to-noise ratio of the GPS / BDS signal to detect the solar radio storm and judge whether it occurs Solar radio burst. In this process, first calculate the solar elevation angle of the observation site and perform data preprocessing, then select the "fall point" and "rise point" to determine the trough time interval of a single satellite at a single observation site, and finally integrate multiple satellites and multiple observation sites to determine the detection results of solar radio bursts. The detection method does not rely on radio telescopes, has a high recognition rate, low cost, and can perform all-weather real-time monitoring.

The invention provides a solar radio total power radiometer system in radio astronomy protection frequency band based on a broadband detection chip. The system works in the radio astronomy protection frequency band and carries out filtering, gating, amplification, detection and analysis on frequency band signals. The system is characterized in that the system is formed by connecting a calibration module and a control unit thereof with a radio-frequency signal detection unit. The beneficial effects of the system are that the system has the advantages that the system receives less radio interference; and compared with a conventional superheterodyne mode, the detection broadband is wider and large in dynamic range, and the structure is simple and the like.

The invention relates to the field of electronic technology, in particular to a solar acousto-optic wireless control single-phase micro-motor stage curtain machine. Including solar power supply, bridge inverter, four stage curtains, four single-phase AC induction micro-motors M1, M2, M3, M4, sound and light control module, wireless remote control transmitter and receiver components, four-rail transmission mechanism, The solar power supply is put into long-term use at one time, and there is no electricity consumption, which is convenient for stage entertainment performances in parks and squares. The single-phase AC induction micro-motor has a large torque, which can pull a large stage curtain. The light becomes stronger when the plot starts. The single-phase AC induction micro-motor rotates forward, automatically pulls the curtain, when the performance ends, the sound drops, the light is dim, there is no signal from the sound and light sensor, the single-phase AC induction micro-motor reverses, the curtain is automatically pulled and closed, and the wireless remote control pulls and closes according to the performance content , flexible and convenient to use, and enhance the effect of cultural and entertainment performances. The invention is suitable for stage performance curtain control.

The present disclosure discloses a solar radio observation instrument, system and method, comprising: two antennas, each of which is connected to the antenna main circuit via a coupler, both antenna main circuits are connected to a digital receiver, and the two couplers The amplitude calibration unit and the phase calibration unit are connected to the digital receiver, and the digital receiver is connected to the host computer; two antennas are used to receive solar radio signals, and the two radio signals are received by the digital receiver after passing through the antenna main circuit to form two time For the data in the two time domains, the host computer calculates the time domain delay of the two time domain data, and sends the time domain delay to the digital receiver for delay compensation of the two time domain data. Eliminate the electromagnetic wave delay of solar radio through a single turntable and dual antennas, and the host computer calculates the compensation factor and sends the FPGA corresponding compensation to achieve real-time compensation while reducing FPGA resource consumption.
