Abstract

The invention discloses a method for controlling switching of VSAT (Very Small Aperture Terminal) satellite communication L-band up and down converters, comprising the following steps of: step 1, system initialization; step 2, entering into a waiting state; and if an input command is detected in the waiting state, entering into step 3; step 3, command determination, and if the determination is true, starting step 4, otherwise, returning to the step 2; step 4, command processing; and step 5, control event processing, and returning to the step 2 if processing is finished. The invention also discloses a device for controlling switching of the VSAT satellite communication L-band up and down converters. With the method and device for controlling switching of the VSAT satellite communication L-band up and down converters provided by the invention, quick control is realized for the control of related modules of the up converter and the down converter, and parameter adjustment and control; real-time operation is realized for the input instructions; the parameter adjustment time is shortened; and the operation reliability and keenness of the satellite signal transmitting / receiving equipment are enhanced.

Description

technical field [0001] The invention belongs to the field of satellite communication, and relates to a switching control method and device for L-band up and down converters of VSAT satellite communication. Background technique [0002] VSAT (Very Small Aperture Terminal, Very Small Aperture Antenna Earth Station) for satellite communication has the characteristics of strong flexibility, high reliability, convenient use, and small stations can be directly installed on the user end. Using VSAT user terminals can be directly connected to the computer network, Complete communication tasks such as data transfer, file exchange, and image transmission, thus getting rid of the problem of long-distance communication ground interruption stations. So it is a good choice to use VSAT as a dedicated long-distance communication system. The so-called small aperture specifically refers to the small aperture of the satellite signal receiving antenna, usually only 1.2 to 2.4 meters. [0003]...
