The invention discloses a single-stop-type internal monitoring design method for a satellite communication vehicle station. An industrial computer is adopted to centrally manage all the truck-loading facilities of the satellite communication vehicle station, and the interfaces of the industrial computer are expanded so as to be connected with all the external devices of the satellite communicationvehicle station; the working state of the external devices are monitored by single-stop-type internal monitoring software; coding is respectively carried out aiming at the interface protocol of eachexternal device to finally form operation interfaces with unified styles; the working flow of the internal monitoring to control a power amplifier switch is as follows: at first, the internal monitoring sends a control command to an Ethernet switch; the control command is encapsulated into an IP data package according to an agreed technical protocol; then the switch switches and transmits the IP data of the control command to the network port of a channel unit according to the target address of the IP data package; afterwards, the channel unit resolves the command according to the protocol togenerate a control signal which controls the high and low power levels of the power amplifier switch; and finally the power amplifier switch is controlled by controlling the power levels of the signal.
