Description

Technical Field

[0001] The present invention relates to the technical field of electronic communications, in particular to a multi-band satellite beacon receiver. Background Art

[0002] The satellite beacon receiver is one of the key parts of the antenna servo in the satellite communication system. It processes the satellite beacon signal (L band) and demodulates the AGC signal and lock indication signal for the antenna servo, so that the antenna can be accurately aligned with the satellite.

[0003] Currently, all beacon receivers on the market are single-band beacon receivers, which are generally divided into L-band, C-band, Ku-band and Ka-band. If a certain earth station has multiple mid-band satellite antennas, it is necessary to configure beacon receivers with multiple frequency bands. Summary of the invention

[0004] The present invention proposes a multi-band satellite beacon receiver, which can receive a variety of different frequency bands, is suitable for antennas of commonly used frequency bands on the market, and has strong compatibility with different frequency bands.

[0005] The technical solution of the present invention is as follows:

[0006] A multi-band satellite beacon receiver includes a power module, the power module is used to power the receiver, and includes a multi-band frequency conversion module, an analog-to-digital integration unit, a main control unit and an interaction module.

[0007] The multi-band frequency conversion module is used to unify the received signals of different frequency bands. The output end of the multi-band frequency conversion module is connected to the analog-to-digital integration unit. The analog-to-digital integration unit signal is connected to the main control unit. The output end of the main control unit is connected to the interactive module.

[0008] The working principle and beneficial effects of the present invention are:

[0009] In the application, the multi-band frequency conversion module receives external RF signals, can receive RF signals of multiple frequency bands, and convert them into L-band signals. The converted signals are removed from the noise by the filtering module and sent to the analog-to-digital integration unit. The analog-to-digital integration unit uses zero intermediate frequency technology to process the input RF signals, converts them into electrical signals and outputs them to the main control unit. The main control unit integrates the input signals and outputs them through the interactive unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] Figure 1 This is a block diagram of the system composition of this application. DETAILED DESCRIPTION

[0012] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] As the instruction manual Figure 1 As shown, a multi-band satellite beacon receiver includes a power module, and the power module is used to power the receiver. It is characterized in that it includes a multi-band frequency conversion module, an analog-to-digital integration unit, a main control unit and an interaction module.

[0014] The multi-band frequency conversion module is used to unify the received signals of different frequency bands. The output end of the multi-band frequency conversion module is connected to the analog-to-digital integration unit. The analog-to-digital integration unit signal is connected to the main control unit. The output end of the main control unit is connected to the interactive module. A filtering module is also arranged between the multi-band frequency conversion module and the analog-to-digital integration unit.

[0015] The main working principle of the multi-band satellite beacon receiver is: the multi-band RF signals such as L-band, C-band, Ku-band and Ka-band are down-converted to L-band through the frequency conversion module and filter module, and then the pre-processing unit filters and differentially processes the signal, and sends it to the analog-to-digital integration unit, which uses zero intermediate frequency technology to convert the RF signal into bit stream data, and at the same time, the signal amplitude information is converted into a voltage signal output through the internal digital-to-analog converter. The power module completes the conversion between AC and DC, and supplies power to each module inside the beacon receiver.

[0016] The multi-band satellite beacon receiver adopts multi-frequency conversion module, digital phase-locked loop, large-scale integrated circuit, high-performance microprocessor and embedded real-time operating system, which makes the product have high stability and humanized human-machine interface.

[0017] The interaction module includes an OLED display screen, buttons, indicator lights and an RS232 transceiver. The receiver realizes human-computer interaction or interaction with other systems with the help of the interaction module.

[0018] The OLED display, buttons and indicator lights are used to realize human-computer interaction, and can be connected to other video modules with the help of RS232 transceiver.

[0019] The analog-to-digital integrated unit is also signal-connected to an analog voltage output port for outputting an analog voltage.

[0020] The analog-to-digital integration unit is used to convert the radio frequency signal into bit stream data, and convert the signal amplitude information into a voltage signal output via an internal digital-to-analog converter.

[0021] The multi-band frequency conversion module outputs an L-band radio frequency signal. The L-band radio frequency signal is relatively stable, and the technology is mature, so that the radio frequency signal can be stably output to the analog-to-digital integrated unit.

[0022] The main control unit can process the digital signal sent by the analog-digital integrated unit, process the signal according to the internal algorithm, and output it through the interactive module.

[0023] The multi-band satellite beacon receiver has a remote monitoring function and is also suitable for application scenarios where large satellite antennas are far away from the control room.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
